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 for protecting the adhesive layer. When the car logo is pasted with the adhesive backing, it is necessary to remove the protective layer on the surface, align the adhesive layer with the back of the logo, and paste it.

[0004] The above glue laminating equipment can only realize the loading, tearing, laminating and discharging of the back glue, and cannot perform front glue laminating, so there is room for improvement. Utility Model Content

[0005] The utility model aims to provide a workpiece upper and lower laminating production line in view of the disadvantages of the existing glue-laminating production line that can only laminar back glue but cannot have upper and lower laminating functions.

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

[0007] A workpiece upper and lower laminating assembly line comprises a workbench and a workpiece back laminating mechanism arranged on the workbench, a workpiece front laminating mechanism and a discharge station spaced apart from the workpiece back laminating mechanism are arranged on the workbench, the workpiece front laminating mechanism comprises an automatic tape dispenser that can automatically spit out adhesive tape of a preset length, a supporting platform for receiving the adhesive tape spitted out by the automatic tape dispenser, and a transfer film laminating assembly, the transfer film laminating assembly comprises a suction module with a suction port facing downward and the suction port switchable between positive pressure and negative pressure, a guide lifting assembly that drives the suction module to rise and fall vertically, and a translation assembly that drives the guide lifting assembly to reciprocate between the discharge station, the supporting platform and the discharge station of the workpiece back laminating mechanism.

[0008] By adopting the above scheme, a front-side laminating mechanism for the workpiece is added, and the workpiece with back-laminated film is transferred to the top of the carrier platform with the front side facing down by using the transfer film-sticking component, and is adhered to the film above the carrier platform during the descent to achieve front-side lamination. The workpiece with upper and lower lamination is then moved to the discharge station for release. The automatic tape machine is an existing equipment. After being combined with the carrier platform and the transfer film-sticking component, it can quantitatively deliver the required film to the carrier platform for the transfer film-sticking component to perform front-side lamination. The assembly line can achieve upper and lower lamination of the workpiece, and the front-side lamination is fully automatic, thereby improving the efficiency of operation.

[0009] Preferably, the translation assembly includes a second bracket fixed on the workbench and a first screw slide assembly arranged on the second bracket, and the guide lifting assembly is arranged on the slide of the first screw slide assembly.

[0010] By adopting the above solution, the screw slide assembly, as a standard part, has the advantage of high precision, which can realize the movement and stop of the guide lifting assembly, thereby realizing the precise stop of the suction module at the discharge station, the load platform and the discharge station.

[0014] By adopting the above solution, the supporting platform can be close to or away from the automatic tape dispenser and the transfer film assembly, reducing assembly errors and lowering the requirements for the installation position and installation spacing of the automatic tape dispenser and the transfer film assembly.

[0015] Preferably, the supporting platform is a film absorption block with adsorption ports evenly distributed on the upper surface thereof, and the adsorption ports of the film absorption block can be switched between positive pressure and negative pressure.

[0016] With the above solution, the supporting platform is a film-absorbing block with an air pressure switching function. The advantage is that it can prevent the film above it from shifting during the movement of the supporting platform, thereby improving the accuracy of the front film lamination.

[0017] Preferably, a downwardly inclined unloading inclined plate is provided at the discharging station, and after the suction module is lowered, it is clearance-matched with the upper end of the inclined surface of the unloading inclined plate.

[0018] With the above solution, when the suction module releases the workpiece, the workpiece slides down along the inclined surface of the unloading ramp into the receiving frame, and the unloading ramp can reduce the collision of the workpiece.

[0021] Preferably, a gluing station is provided between the back glue pasting station and the discharging station to ensure that the adhesive layer of the back glue is firmly adhered to the workpiece. A gluing assembly is provided on the gluing station, which includes a gluing block, a guide assembly for driving the gluing block to vertically guide and lift, and a gluing cylinder.

[0022] By adopting the above solution, the glue pressing component can further compact the adhesive, making the combination of the adhesive and the workpiece more uniform and firm.

[0023] Preferably, a plurality of groups of positioning components for positioning and storing redundant workpiece positioning molds are provided on the working turntable, and each group of positioning components includes at least two positioning pins which are vertically arranged and can be plugged into the workpiece positioning mold.

[0024] By adopting the above solution, the positioning component can position multiple idle workpiece positioning molds, thereby increasing space utilization.

[0025] The utility model has significant technical effects due to the adoption of the above technical solutions: the assembly line is equipped with both a workpiece back laminating mechanism and a workpiece front laminating mechanism. After the back of the workpiece is laminarized, the transfer film laminating assembly is used to transfer the workpiece with the back film laminarized to the top of the carrier platform with the front side facing down, and during the descent process, it is adhered to the film above the carrier platform to achieve front lamination.
