Abstract

The invention relates to the technical field of spraying production lines, and discloses an automatic hanging device for a part to be sprayed of a spraying production line, which comprises two fixing plates, a conveyor belt is arranged between the two fixing plates, the first push plate with the special triangular pointed cone-shaped positioning block is driven by the electric push rod to actively move, so that the accurate forced positioning and posture correction of the workpiece on the conveying belt are realized. When the workpiece is conveyed to the vicinity of the grabbing area, the first positioning block and the second positioning block form physical blocking and guiding at the front of the advancing direction of the workpiece, and through the cooperation of the fixed rod and the inclined hole on the inclined plate, the second positioning block can horizontally move and simultaneously generate transverse displacement in the advancing process of the push plate, so that the workpiece is righted from the side surface, and the workpiece is accurately guided and fixed below the grabbing center of the mechanical arm. The mechanism fundamentally avoids the grabbing failure caused by random stopping of the workpieces, ensures the unification of the reference positions of each hanging action, and greatly improves the grabbing success rate and precision of the mechanical arm.

Description

Automatic hanging device for to-be-sprayed part of spraying assembly line Technical Field The invention relates to the technical field of spraying pipelines, in particular to an automatic hanging device for a part to be sprayed of a spraying pipeline. Background In the process of manufacturing the lifting table, plastic spraying treatment is required to be carried out on the surfaces of the table frame, the table legs and other metal parts of the lifting table so as to prevent the surfaces of the metal parts from rusting. At present, the plastic spraying of the metal parts of the lifting table is generally carried out on a spraying assembly line, and the spraying assembly line generally comprises the process steps of feeding, transporting, cleaning, drying, plastic spraying and the like. When spraying the metalwork, the manipulator is usually adopted to grab the metalwork on the conveyor belt onto the hanging conveying chain, the front-stage staff can place the workpiece on the conveyor belt in a group of every two, and the later-stage manipulator is convenient for grab the metal part after the conveyor belt conveys the workpiece to the locating area, but because the problems of belt deviation, uneven tensioning and the like can lead to the metal part to be unable to be accurately positioned to the locating area below the manipulator, and the grabbing effect of the manipulator is affected. Disclosure of Invention The invention aims to solve the technical problem of providing an automatic hanging device for a piece to be sprayed of a spraying assembly line, aiming at the defects in the prior art. In order to solve the technical problems, the automatic hanging device for the to-be-sprayed parts of the spraying assembly line comprises two fixing plates, a conveying belt is arranged between the two fixing plates, a hanging conveying chain is arranged on the right side of the conveying belt, a supporting box is fixedly connected to the bottom of the fixing plate, a supporting plate is fixedly connected to the front side of the supporting box, a mechanical claw hand is arranged at the top of the supporting plate, two suckers are arranged at one end, far away from the supporting plate, of the mechanical claw hand, a positioning mechanism is arranged at the top of the conveying belt, the positioning mechanism comprises an electric push rod, the electric push rod is fixedly connected to the front side of the fixing plate, a transverse plate is fixedly connected to the front side of the electric push rod, a first movable rod is fixedly connected to the back of the transverse plate and movably penetrates through the fixing plate to the back of the fixing plate, a first push plate is fixedly connected to the back of the first movable rod, a first positioning block is fixedly connected to the back of the first push plate, a second positioning block is arranged at the back of the first push plate, and one end, far away from the first conical tip angle positioning block is arranged at the back of the first push plate. Preferably, a sliding groove is formed in the back of the first pushing plate, a sliding block is connected inside the sliding groove in a sliding mode, the sliding block is fixedly connected with the second positioning block, and a first spring is fixedly connected between the sliding block and the sliding groove. Preferably, the top fixedly connected with riser of fixed plate, the top fixedly connected with swash plate of riser, the inclined hole has been seted up to the inside of swash plate, the top fixedly connected with dead lever of second locating piece, the inclined hole cover is established at the top of dead lever, and the conveyer belt is continuous to be operated, will be preceded the manual work or the equipment is placed wait to spray the work piece and snatch the station transport to the right side, when the work piece moves to being close to snatch the station along with the conveyer belt, through control system control conveyer belt stop operation, after control system received the signal, start positioning mechanism's electric putter stretches out. The electric push rod drives the first push plate to move towards the direction of the conveying belt through the transverse plate and the first movable rod, and when the first push plate moves forwards, the first positioning block on the first push plate is driven to synchronously move forwards. Meanwhile, the square plate of the deviation preventing mechanism is driven to transversely move through the first connecting plate. The second positioning block is matched with the inclined hole fixed on the inclined plate through the fixed rod at the top of the second positioning block. Due to the guiding function of the inclined hole, the fixed rod slides along the inclined hole while the first push plate horizontally advances, so that the second positioning block is forced to overcome the elastic force of the first spring under the constraint of the
