Description

Clamping device for feeding plastic sucking disc Technical Field The invention relates to the technical field of plastic sucking disc feeding, in particular to a clamping device for plastic sucking disc feeding. Background The plastic sucking disc is used as one kind of common plastic product and is produced through mainly vacuum molding process, and has the specific operation of heating and softening plastic sheet, adhering the plastic sheet to the surface of mold with vacuum or pressure, cooling to form dish with specific shape and structure, portability, high durability, high waterproof and moistureproof performance, etc. and is used in packing and showing fresh food, such as fruit, vegetable, meat, etc. in food industry, the plastic sucking disc is used as antistatic tray for providing safe transportation and storage environment for precise electronic components. The Chinese patent document with the publication number of CN216104778U discloses a tray material taking clamp which comprises a sliding rail and a clamping assembly, wherein the clamping assembly comprises a base and a clamp, the base is longitudinally and slidably connected with the sliding rail, the clamp is fixedly connected with the base, a plastic sucking disc for sucking a plurality of materials is placed at one end of the sliding rail, and one end of the plastic sucking disc is clamped by the clamp to longitudinally move into a tray storage mechanism. When the automatic feeding device is used, hard product trays are manually fed, the hard product trays are separated, the separated hard product trays flow out to a conveying belt, a plurality of materials are arranged on each hard tray, a camera is used for shooting and positioning, a goods placing suction nozzle sucks the products on the hard tray, namely the materials, if the empty hard trays flow to the tail of a belt for collection, otherwise, a fly shooting fine positioning machine performs secondary positioning, the goods placing suction nozzle transversely moves along a portal frame to suck the materials from the hard tray respectively, then transversely moves to the upper side of the plastic sucking tray, places the materials on a plastic sucking placing grid of the plastic sucking tray, circularly places the materials until the plastic sucking placing grid is completely placed, a tray material taking clamp clamps the plastic sucking tray, the fully placed plastic sucking tray is retracted into a storage mechanism, the storage mechanism downwards moves a station, the tray material taking clamp clamps a new plastic sucking tray, and the operation is repeated to start placing the materials. However, the above patent document has the disadvantage that in the feeding process of the plastic trays, since the plastic trays are generally stacked together, the gravity of the upper plastic tray will press the lower plastic tray, resulting in a certain degree of deformation, which may not be significant when stacking single or small number of plastic trays, but as the stacking number increases, the pressure born by each plastic tray also increases, especially when stacking to a certain height, the four corners of the plastic tray will have a significant height difference due to uneven stress, and this height difference easily causes that the fixture cannot accurately clamp the target plastic tray, thereby affecting the subsequent operation efficiency. Disclosure of Invention The invention provides a clamping device for feeding plastic sucking discs, and aims to solve the problems that in the prior art, a plurality of plastic sucking discs are stacked, the pressure applied to the plastic sucking discs below is large, and obvious height differences are easily generated at four corners of the plastic sucking discs due to uneven stress, so that a clamp cannot accurately clamp a target plastic sucking disc.
