Description

Positioning device of film sticking machine Technical Field The utility model belongs to the technical field of electronic product film sticking equipment, and particularly relates to a positioning device of a film sticking machine. Background Currently, electronic devices are increasingly used, and for these intelligent electronic devices, a screen is generally provided with a touch function, and a user touches a key to conduct communication or touches a menu to acquire information on the screen through the conductive characteristic of a finger. In order to prevent scratches caused by frequent touching or friction by external force on the screen surface, a film needs to be attached to the screen. The traditional film sticking machine is mainly used for carrying out preliminary positioning on film sticking materials (such as a protective film, an optical film and the like) and products to be stuck with films (such as a screen, a glass panel and the like) in a mechanical clamping or vacuum adsorption mode. However, the prior art suffers from the following significant drawbacks: 1. The positioning accuracy is insufficient, the conventional film sticking machine depends on a positioning reference (such as edge alignment) in a single direction, and a multi-degree-of-freedom cooperative adjustment mechanism is lacked. In the process of film tearing, due to the accumulation of tiny displacement between the film material and the product, bubble residues or film layer wrinkles are easily caused during subsequent pushing and exhausting, and the film is more obvious especially in curved surfaces or special-shaped products. 2. The dynamic stability is lost, and when the existing device is used for switching the film tearing process and the pushing process, the preset spatial relationship between the film material and the product is difficult to maintain. For example, vacuum adsorption positioning is prone to local detachment due to film tension changes, while mechanical clamping may cause product surface scratches due to rigid contact. 3. The adaptability is limited in that the prior art generally adopts a fixed positioning structure, and cannot be compatible with the combination of film materials and products with different sizes or thickness specifications. Although some devices are additionally provided with manual adjusting modules, the adjusting efficiency is low and high-precision repeated positioning is difficult to realize. Disclosure of utility model The utility model aims to provide a positioning device of a film sticking machine, which can accurately position film sticking materials and products to be film sticking so as to ensure that the film sticking materials and the products to be film sticking always maintain a preset spatial relationship in the follow-up film tearing and pushing and exhausting processes, and improve film sticking precision. In order to solve the technical problems, the utility model adopts the following technical scheme: A positioning device of a film sticking machine comprises a machine body and a positioning mechanism, wherein a top plate of the machine body is provided with a placement area for placing a film sticking product and positioning blocks which are arranged on the outer side of the placement area and used for positioning film sticking materials, the positioning blocks are matched with positioning holes preset in a first release film of the film sticking materials, the positioning mechanism is arranged on the machine body and can position and fix the film sticking product to be placed on the placement area so that the center line of the film sticking product to be placed coincides with the center line of the film sticking materials, the positioning mechanism comprises a centering component and a pushing component, the centering component comprises a centering chuck and a first driving component, the two centering chucks and the first driving component are symmetrically arranged on the left side and the right side of the placement area, the output ends of the first driving component are respectively connected with the two centering chucks and can drive the two centering chucks to move in opposite directions or move in the back direction, the pushing component is provided with a pushing chuck and a second driving component, the pushing chuck is arranged on the side of the placement area and can be abutted against the front end of the machine body, and the driving end can be abutted against the front end of the machine body and the front end of the driving chuck is arranged on the front end of the machine body, and the front end of the driving chuck can be abutted against the front end of the machine body to realize the positioning of the positioning. As a preferable scheme of the utility model, the front side of the machine body is provided with a boss, and the boss protrudes upwards from the top plate of the machine body and forms the limit flange at the front end of the p
