Description

Technical Field

[0001] The utility model relates to the technical field of marking workpiece processing, in particular to a workpiece adhesive pasting device. Background Art

[0002] Logo parts, such as car logos, need to have adhesive backing pasted on the back after production. The adhesive backing consists of three layers when leaving the factory: the middle layer is the adhesive layer, and the two layers on the upper and lower surfaces are protective layers that protect the adhesive layer. When the car logo is pasted to the adhesive backing, it is necessary to first remove the protective layer on the surface, align the adhesive layer with the back of the logo and paste it. When the car logo is pasted to the rear of the car, remove the other protective layer.

[0003] Initially, both the adhesive backing and the surface lamination required manual labor. During the pasting process, alignment was difficult, and the pasting efficiency and quality were both low. To address the problems caused by manual operation, Chinese Patent Publication No. CN203045285U discloses an assembly device for automobile identification plates, which includes a workbench, a cylinder, an adsorption plate for adsorbing decorative parts, and a placement table for accurately placing a lower base with adhesive tape. The placement table is fixedly mounted on the workbench, directly below the adsorption plate. A support frame is fixedly mounted on the workbench, and the cylinder is fixedly mounted on the support frame. The cylinder is connected to the adsorption plate via a drive shaft. The advantage of this solution is that the adsorption plate's adsorption effect on the decorative parts and its mechanical positioning function allow for accurate and rapid assembly with the lower base with adhesive tape placed on the placement table.

[0004] In the above-mentioned equipment, the workpiece is sucked and placed on the adhesive backing for pasting. However, in actual operation, the positioning of the workpiece is easy and quick to achieve, and the adhesive backing is a thin layer, and its bottom protective layer is difficult to tear off. As a result, the steps of taking the adhesive backing, removing the bottom protective layer, and positioning and pasting on the back of the workpiece are very time-consuming, affecting efficiency. In the above-mentioned scheme, the steps of taking the adhesive backing, removing the adhesive backing protective layer, etc. still require manual operation, so there is room for improvement. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art that manual operation is required for taking the adhesive and removing the adhesive protective layer, and provides a workpiece adhesive pasting device which can automatically load the adhesive and automatically paste the adhesive to the workpiece.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A workpiece back glue pasting device includes a glue suction module with a suction port facing downward, a workbench, and a gluing station, a glue tearing station and a glue sticking station arranged on the workbench in sequence. The glue suction module can be raised and lowered vertically and absorb, press down or release the back glue during the lifting and lowering process. The glue suction module can reciprocate and translate between the three stations. The lifting or translation of the suction module is controlled by a driving component. The gluing station is provided with a glue storage and gluing component that can stack multiple back glues vertically and deliver the back glues upward one by one. The glue tearing station is provided with a glue tearing component that can absorb the bottom protective layer of the back glue and tear it from one end of the protective layer to the other end.

[0008] Using the above solution, the glue storage and gluing component is used to store glue and deliver the back glue upward one by one. The film pasting process is as follows: the glue suction module first descends and uses negative pressure to suck the back glue on the top of the glue storage and gluing part; then, it carries the back glue up and moves horizontally to the glue tearing component; then, the glue tearing component tears off the bottom protective layer; then, the glue suction module carries the back glue with the protective layer removed and moves horizontally to the top of the product at the film pasting station; then, the glue suction module descends and presses the back glue down for gluing; finally, the glue suction module switches to normal pressure and rises to reset. The equipment can automatically take glue, tear off the protective layer and stick glue, with a high degree of automation, which significantly improves the efficiency of back glue pasting.

[0009] Preferably, the glue tearing assembly includes a glue tearing module with an upward suction port and switchable between positive pressure and negative pressure, a lifting guide assembly that drives the glue tearing module to rise and fall vertically, and a translation drive assembly that drives the lifting guide assembly to translate in a direction perpendicular to the translation direction of the glue suction module.

[0010] Preferably, the lifting guide assembly includes a horizontally arranged mounting plate and a guide seat vertically fixed to the mounting plate and capable of vertically guiding the glue tearing module. A first lifting cylinder for driving the glue tearing module to move up and down along the guide seat is installed at the bottom of the mounting plate.

[0011] Preferably, the translation drive assembly includes a fixed plate fixed to the workbench and coordinated with the horizontal guide of the mounting plate, a drive motor arranged at the lower end of the fixed plate, and a drive gear arranged on the motor shaft of the drive motor. The drive gear is located between the fixed plate and the mounting plate, and a rack meshing with the drive gear is fixed at the lower end of the mounting plate.

[0012] Using the above solution, the glue-tearing module first rises and sucks one end of the bottom of the adhesive backing; then, the glue-tearing module descends and lifts the end part of the protective layer; then, the glue-tearing module translates toward the other end and peels off the entire protective layer from the bottom of the adhesive backing during the translation; then, the glue-tearing module carries the protective layer down away from the adhesive backing; finally, the glue-tearing module switches to positive pressure or normal pressure, allowing the protective layer to slide off it.

[0013] Preferably, the length of the glue-tearing module along its translation direction is ≤ 1 / 3 of the length of the glue-absorbing module in the same direction.

[0014] With the above solution, the effective contact area between the glue tearing module and the protective layer needs to be as small as possible, and tearing the film will be more labor-saving. Therefore, it is necessary to reduce the adsorption area while ensuring adsorption with one end of the protective layer.

[0015] Preferably, the glue storage and gluing assembly includes a glue lifting platform for stacking the back glue, a vertical guide assembly for driving the glue lifting platform to vertically guide and lift, and an electric push rod for driving the glue lifting platform to lift and lift.

[0016] Preferably, at least two positioning posts are vertically protruded on the glue lifting platform, which can pass through the adhesive protective layer without contacting the adhesive layer.

[0017] By adopting the above solution, the glue storage and gluing assembly can vertically stack the adhesive and vertically lift the adhesive one by one. The above design can ensure the lifting accuracy.

[0018] Preferably, the drive assembly includes a bracket vertically fixed on the workbench and a screw slide assembly installed on the bracket, a mounting seat is fixed on the slide of the screw slide assembly, and a guide drive component for driving the glue suction module to vertically rise and fall is installed on the mounting seat.

[0019] Preferably, the guide drive component includes a second lifting cylinder fixed on the mounting seat, the piston rod of the second lifting cylinder is vertically downward and the end is fixed with a connecting plate fixed to the bottom and the top of the glue suction module, the connecting plate is vertically guided and slid on the mounting seat, and a makeshift groove is provided on the connecting plate for the screw of the screw slide assembly to pass through and move vertically relative to the screw.

[0020] By adopting the above scheme, the glue suction module realizes vertical lifting movement under the guidance of the second lifting cylinder and the connecting plate, and the mounting seat equipped with the second lifting cylinder and the connecting plate can realize precise translation with the cooperation of the screw slide assembly, and realize the precise positioning of the glue suction module at the gluing station, glue tearing station and glue sticking station.

[0021] The utility model adopts the above technical scheme, which has significant technical effects: the adhesive backing pasting device stores adhesive and delivers the adhesive upward one by one by the adhesive storage and gluing component, and tears off the protective layer at the bottom of the adhesive backing by the adhesive tearing module. Under the action of a adhesive suction module and a driving component that drives it to rise, fall and translate, the adhesive backing provided by the adhesive backing component is absorbed at the adhesive backing station, and the adhesive backing provided by the adhesive backing component is carried to the adhesive tearing station for the adhesive tearing module to tear off the protective layer. Finally, the adhesive backing with the torn protective layer is carried to the adhesive pasting station, and the adhesive backing is released and automatically reset after being lowered to paste the adhesive. The device can automatically take out adhesive, tear off the protective layer and adhere adhesive, with a high degree of automation, which significantly improves the efficiency of adhesive pasting.
