TECHNICAL FIELD

[0001] The utility model relates to camera module assembly production technical field especially relates to a kind of stripping single tear film structure. BACKGROUND

[0002] In the production process of small camera module, PCB (product) will be usually fixed on the steel sheet with adhesive film, to facilitate the production of front-end process. And after completing certain process, automatic stripping single equipment is needed to strip PCB from the adhesive carrier plate (steel sheet).

[0003] At present, most of the automatic stripping single equipment is only applicable to the front-end carrier plate (steel sheet) with notch, that is to say, the film tearing clamp must pass through the notch in the front end of the steel sheet to clamp the adhesive film. However, the steel sheet used by some customers is complete without notch, and the adhesive film is not exposed, so the film tearing clamp cannot clamp the adhesive film, and automatic online stripping single cannot be performed, which affects the production efficiency. Therefore, the technical personnel in the field provide a kind of stripping single tear film structure to solve the problems raised in the above background technology. UTILITY MODEL CONTENT

[0004] The utility model discloses a kind of stripping single tear film structure to solve the shortcomings in the prior art, can satisfy the automatic stripping single production demand of customer using no-notch steel sheet, eliminate the investment cost of customer to transform steel sheet, overall structure is compact, can be installed in the online stripping single equipment of small space, high degree of automation is integrated, improve production efficiency.

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] A kind of stripping single tear film structure, including tear film lifting assembly and tear film platform component, the upper end surface of the tear film lifting assembly is fixedly connected with pressure film component, installation seat is slidably arranged in the tear film lifting assembly, the side of the installation seat is movably provided with film clamping component, the film clamping component includes mounting bracket, the front end surface of the mounting bracket is fixedly connected with film clamping fixed plate at rear, the front end surface of the mounting bracket is rotatably connected with film clamping movable plate, the front end surface of the mounting bracket is connected with film clamping cylinder below, the active end of the film clamping cylinder is fixedly connected with film clamping movable plate, the tear film platform component includes fixed frame, the upper end inner wall of the fixed frame is fixedly connected with one avoids position cylinder, the upper end surface of the one avoids position cylinder is fixedly connected with carrier plate track platform, one side of the carrier plate track platform is fixedly connected with adsorption plate, the pressure film component includes two avoids position cylinders, one side of the two avoids position cylinders is fixedly connected with pressure film lifting cylinder, the lower end of the pressure film lifting cylinder is fixedly connected with pressure film plate;

[0007] With the above technical solution, during use, the steel sheet is pushed out by the steel sheet pushing structure until its front end overlaps with the front end of the carrier plate track platform by about 1mm and then stops. The film pressing lifting cylinder and the second avoidance cylinder move simultaneously, thereby driving the film pressing plate to move. The film pressing plate presses off a small section of adhesive film at the front end of the steel sheet and causes it to droop. The film clamping assembly moves upward under the action of the film tearing lifting assembly, and through the operation of the film clamping cylinder, the film clamping movable plate is tilted under force. The film clamping movable plate contacts the film clamping end of the film clamping fixed plate, thus clamping the small section of adhesive film that has detached. The stripping platform at the end changes from its original open state to a closed state, leaving a narrow gap between it and the fixed platform, allowing only the adhesive film to pass through. The film clamping assembly moves downward under the action of the film tearing lifting assembly, pulling the adhesive film away from the steel sheet, so that the PCB is peeled off row by row on the plane. The product is then picked up by the material picking wall. This can meet the customer's needs for automatic stripping production using steel sheets without gaps, eliminating the investment cost for customers to modify the steel sheets. The overall structure is compact and can be installed in online stripping equipment in small spaces. It has a high degree of automation integration and improves production efficiency.

[0008] Furthermore, both sides of the mounting frame are fixedly connected to lower fixing rings, and each of the lower fixing rings is fixedly connected to a return spring. Both sides of the membrane movable plate are fixedly connected to upper fixing rings, and the upper ends of the two return springs are respectively fixedly connected to the corresponding upper fixing rings.

[0009] The above technical solution, with its upper fixing ring, reset spring, and lower fixing ring, can achieve a better reset effect on the membrane clamping plate.

[0010] Furthermore, a fixing plate is fixedly connected to one side of the front end face of the film-tearing lifting assembly, a chain is fixedly connected to the fixing plate, and a connecting pad is fixedly connected to the other end of the chain, with the connecting pad being fixedly connected to the fixing plate.

[0011] The above technical solution allows for better positioning of the membrane clamping assembly via the set chain.

[0012] Furthermore, a steel sheet recycling box is fixedly connected to one side of the film-tearing platform assembly;

[0013] The above technical solution achieves the recycling of steel sheets after the adhesive film has been removed by setting up a steel sheet recycling box.

[0014] Furthermore, limit pads are fixedly connected to the lower end face of the carrier track platform at both the front and rear positions.

[0015] The above technical solution achieves stable movement through the setting of limiting pads.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes a single-piece film-peeling structure. In use, a steel sheet is pushed out by a steel sheet pushing structure until its front end overlaps with the front end of the carrier plate track platform by approximately 1mm, then stops. Simultaneously, the film-pressing lifting cylinder and the second-stage avoidance cylinder move, thereby moving the film-pressing plate. The film-pressing plate presses off a small section of the film at the front end of the steel sheet, causing it to droop. The film-clamping assembly moves upward under the action of the film-peeling lifting assembly, and through the operation of the film-clamping cylinder, the film-clamping movable plate tilts under force. The film-clamping movable plate contacts the film-clamping fixed plate at its clamping end, thus clamping the drooping small section of film. The lower stripping platform of the adhesive film changes from its original open state to a closed state, leaving a narrow gap between it and the fixed platform, allowing only the adhesive film to pass through. The film clamping assembly moves downward under the action of the film tearing lifting assembly, pulling the adhesive film away from the steel sheet, so that the PCB is peeled off row by row on the plane. The product is then picked up by the material picking wall. This can meet the customer's needs for automatic stripping production using steel sheets without gaps, eliminating the investment cost of modifying the steel sheet for the customer. The overall structure is compact and can be installed in online stripping equipment in small spaces. It has a high degree of automation integration and improves production efficiency.
