Description

Technical Field

[0001] This invention relates to the technical field of automobiles, and more specifically to an integrated tailgate pressing device with an upper mold. Background Technology

[0002] A car tailgate consists of an upper trim panel, glass, a middle trim panel, a lower trim panel, taillights, high-mounted brake lights, an inner lining panel, hinges, and wiring harnesses. With the development of the new energy vehicle industry and the rise of emerging car manufacturers in recent years, automakers have transformed their tailgate manufacturing processes. Traditional tailgate manufacturing involved assembling painted sheet metal and injection-molded inner lining panels. In the new process, sheet metal parts are replaced by injection-molded materials, and assembly processes are replaced by gluing processes.

[0003] The existing technology still has the following areas for improvement: the existing tailgate pressing fixtures are all split-type, with the upper trim panel fixture and the middle and lower trim panel fixtures being separate. The robot gripper has to extract the two sets of fixtures in two separate steps, which cannot press multiple parts at the same time. An additional set of fixtures is required, and the bonding and pressing are done in two steps, which is costly. The process is cumbersome, with secondary positioning and bonding and pressing of the inner panel, resulting in low efficiency. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention provides an integrated tailgate pressing device with an upper mold, which can simultaneously bond three exterior trim panels to the inner lining panel, achieving rapid, stable, and efficient bonding, precise positioning, and simultaneous pressing of multiple workpieces, thereby improving cycle efficiency.

[0005] The objective of this invention can be achieved through the following technical solutions:

The base plate is fixedly connected to the frame, and the two second upper mounting plates are both fixedly connected to the frame. The two second upper mounting plates are both located on the rear side of the base plate.

[0008] Each of the second upper mounting plates is fixedly connected to the middle position of a second cylinder, one end of each of the two second cylinders is fixedly connected to the second lower mounting plate, and multiple upper contour blocks are fixedly provided on the other end of the second lower mounting plate.

[0009] The floating assembly includes a first lower mounting plate, two first upper mounting plates, and two first cylinders. The two first upper mounting plates are fixedly connected to the frame and are located on the front side of the base plate.

[0010] Each of the first upper mounting plates is fixedly connected to the middle position of one of the first cylinders, one end of each of the two first cylinders is fixedly connected to the first lower mounting plate, and multiple side contour blocks are fixedly provided on the other end of each of the first lower mounting plates.

[0011] The lower mold assembly includes a base frame, eight air distribution blocks, and eight clamping components. Two air distribution blocks and two clamping components are fixedly connected to the four sides of the base frame, and the two clamping components on each side are located outside the two air distribution blocks. Multiple lower contour blocks are fixedly arranged on the top of the base frame.

[0012] Furthermore, the tailgate assembly includes an inner panel, an upper trim panel, a middle trim panel, and a wiring harness. The upper trim panel and the middle trim panel are both located above the inner panel, the middle trim panel is located in front of the upper trim panel, and the wiring harness is located on the inner panel.

[0013] Furthermore, two first mounting seats and two upper connectors are respectively provided on the front and rear sides of the frame, and the two upper connectors on the same side are respectively located outside the two first mounting seats. Two second mounting seats are respectively provided on the left and right sides of the frame.

[0014] Furthermore, an upper positioning component is fixedly installed at the middle position on both the front and rear sides of the frame, and a flange is fixedly installed on the top of the frame, with a robotic arm connected to the flange.

[0015] Furthermore, each of the upper contour blocks is provided with an upper suction cup, and each of the side contour blocks is provided with a side suction cup.

[0016] Furthermore, two bottom brackets are fixedly installed on the lower end of the bottom frame, and a lower positioning component is fixedly installed in the middle position on both the front and rear sides of the bottom frame.

[0017] Furthermore, an electrical box is fixedly installed on the rear side of the bottom frame.

[0018] Furthermore, a sensor is fixedly installed at the connection between each of the first cylinders and the first lower mounting plate, and a limiter is fixedly installed at the lower end of each of the first upper mounting plates.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) By setting up an upper mold assembly and a lower mold assembly, the technical effect that can be achieved is that the upper mold assembly and the lower mold assembly can simultaneously bond the upper trim panel and the middle trim panel to the inner panel. By driving the upper mold assembly to press down through the robotic arm, the upper trim panel and the middle trim panel adsorbed on the upper mold assembly are moved downwards at the same time. The inner panel is located on the lower mold assembly, the distance between the upper mold assembly and the lower mold assembly is reduced, and the upper trim panel, the middle trim panel and the inner panel are pressed together, so that they can be quickly bonded, stable and efficient, and improve cycle efficiency. Through the cooperation between the upper connector and the lower connector, precise positioning can be achieved, preventing the phenomenon of part damage or insecure pressing caused by displacement during pressing.

[0022] (2) By setting up a floating component, the technical effect that can be achieved is that the floating component drives the first lower mounting plate to move downward through the first cylinder, which in turn drives the side suction cup to move downward. The side suction cup located at the center of the side profile block adsorbs the middle trim panel, which can fix the middle trim panel and facilitate the movement of the middle trim panel. The limiter is fixedly set on the first lower mounting plate. When the first cylinder retracts, the first upper mounting plate will stop the movement of the first cylinder when it contacts the limiter, which can help ensure the stability of the up and down movement of the first cylinder. The sensor is located on the first upper mounting plate. The sensor can monitor the up and down movement process of the first cylinder and output the equipment signal.

[0023] (3) By setting the upper mold assembly, the technical effect that can be achieved is that the upper suction cup located at the center of the upper contour block can adsorb the upper trim panel, which can fix the upper trim panel, facilitate the movement of the upper trim panel and prevent the upper trim panel from falling off. The first mounting base and the upper connecting piece are located on the front and rear sides of the frame, which facilitates the positioning and fixing of the front and rear sides of the upper mold assembly. The second mounting base is located on the left and right sides of the frame, which facilitates the positioning and fixing of the left and right sides of the upper mold assembly.

[0024] (4) By setting the lower mold assembly, the technical effect that can be achieved is that the clamping part rotates inside, the clamping part contacts and presses the upper end of the first mounting seat and the second mounting seat, which is convenient for fixing and positioning the position of the lower mold assembly, preventing the upper mold assembly and the lower mold assembly from being misaligned and unable to press together, the lower contour block fits with the inner plate, which is convenient for placing and positioning the inner plate, and the lower connecting parts are all located on the front and rear sides of the bottom frame, which is convenient for positioning and fixing the front and rear sides of the lower mold assembly.
