[0002] In the automotive parts manufacturing industry, the application of automotive bright trim strips is an important process to enhance the appearance and texture of vehicles. Among them, the application accuracy and efficiency of the bright trim strips for license plate frames directly affect the smoothness of the production process. Currently, the traditional application of bright trim strips for license plate frames mainly relies on manual operation. From the positioning of the bright trim strips and the application of adhesive to the alignment and application with the license plate frame, each step requires excessive manual intervention.

[0003] This manual bonding method not only suffers from low operational efficiency, but is also prone to quality problems such as misalignment of the bright trim strip and weak bonding due to human error, increasing subsequent rework costs. More importantly, the traditional bonding process lacks an automated unloading mechanism. After the license plate frame bright trim strip is bonded, the finished product cannot be automatically pushed to the designated area, and manual handling and unloading are still required, further extending the production cycle. It is also difficult to adapt to the automation and assembly line operation requirements of modern automotive parts production, thus restricting the improvement of overall production efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This embodiment of a device for bonding automotive trim strips includes an operating table 1. A base 9, a support frame 2, and side frames 241 symmetrically distributed on both sides of the base 9 are fixed to the top of the operating table 1. A pressing assembly is installed on the support frame 2 for pressing the trim strip onto the upper edge of the license plate frame. A clamping assembly is installed on the side frames 241 for clamping and fixing the license plate frame. A sliding plate 10 is slidably connected to the top of the base 9 and is fixed with screws; its position is adjustable. Two sets of support blocks 11 are slidably connected to the sliding plate 10. Multiple rubber pads 14 are fixed to the top of each support block 11. The support block 11 is used to support the license plate frame and avoid contact with the support block to prevent wear. An elastic component is provided between the support block 11 and the slide plate 10. The elastic component is used to drive the support block to automatically reset. The opposite sides of the support block 11 form a slope. A push component is also installed on the surface of the slide plate 10. The push end of the push component is fixed with a trapezoidal protrusion 22, which can extend to the support block 11. The slope opens the two sets of support blocks 11, so that the upper edge of the license plate frame can avoid sticking to the pad. The top of the protrusion 22 is fixed with a push block 23 extending to the top of the support block 11, which is used to push the finished license plate frame to be unloaded.

[0024] like Figure 5The elastic component includes a slot formed between the support block 11 and the slide plate 10. A protrusion 12 is fixed on the opposite side of the support block 11 and the slide plate 10 in the slot. A spring 13 is sleeved between the opposite protrusions 12. The spring 13 can drive the support block 11 to automatically reset.

[0025] Among them, the top of the slide plate 10 is fixed with a T-shaped rubber head 261 between the support blocks 11. The bottom of the T-shaped rubber head 261 is a metal rod and the top end is a rubber head. The support blocks 11 are provided with grooves that fit the T-shaped rubber head 261 on opposite sides. The support blocks are moved and reset by the spring. With the cooperation of the groove and the T-shaped rubber head, the support blocks can be limited to avoid collision and damage during the reset process.

[0026] like Figure 3 The clamping assembly includes a clamping plate 251 fixed to the top of the side frame 241. A push cylinder 26 and a guide rod 27 are installed on the clamping plate 251. The piston rod of the push cylinder 26 is fixed with a clamping plate 28 connected to the guide rod 27. The clamping plate 28 is L-shaped. The guide rod 27 can ensure that the clamping plate 28 moves smoothly during clamping. At the same time, the L-shaped clamping plate can be moved by the push cylinder to clamp and fix the license plate frame placed between the support blocks.

[0027] like Figure 1-5 The pressing assembly includes two sets of lower-push cylinders 7 fixed to the top of the stand 2 and two sets of columns 8 passing through. The piston rod of the lower-push cylinder 7 is fixed to the mounting plate 3 which is fixedly connected to the column 8. The bottom of the mounting plate 3 is slidably connected to a pressure plate 4 which is fixed by screws. The pressure plate 4 is L-shaped and can be adjusted to match the fitting position of the license plate frame. A pair of guide posts 5 and a pair of first buffers 6 are fixed to the bottom of the pressure plate 4. Correspondingly, a first guide cylinder 15 adapted to the guide post 5 is fixed to the top of the slide plate 10, and a second guide cylinder 16 adapted to the first buffer 6 is fixed on the support block 11. The guide post 5 and the guide cylinder cooperate to ensure the pressing positioning accuracy, and the first buffer 6 can prevent the impact force from damaging the workpiece during pressing.

[0028] like Figure 3-6 The pushing assembly includes an upper plate 17 fixed to the top of the slide plate 10 and a side plate 18 on the back. A pushing cylinder 19 is installed on the side plate 18. A pushing plate 20 is fixed to the piston rod of the pushing cylinder 19. A pair of connecting rods 21 that pass through the upper plate 17 are fixed on the pushing plate 20. A connecting plate 211 is fixed between the connecting rods 21. A protrusion 22 is fixed on the connecting plate 211. The pushing action is stable by sliding the connecting rods with the upper plate. During pushing, the protrusion and the pushing block move synchronously, so that the support block can move relative to each other, so that the license plate frame and the pad block do not stick together. At the same time, the license plate frame can be pushed out by the pushing block to complete the unloading. During the pushing process, the rod of the T-shaped rubber head 261 limits the protrusion.

[0029] Each support block 11 has a baffle 25 installed on its back, and the slide plate 10 has two sets of second buffers 24 installed on its back, which are respectively opposite to the baffles 25, to prevent the support block 11 from being stretched too much and to play a buffering role.

[0030] The working principle of the above embodiments is as follows:

[0031] First, loosen the locking screws between the slide plate and the base, and slide to adjust the overall position of the slide plate. Then, loosen the locking screws between the pressure plate and the mounting plate, and adjust the pressing position of the pressure plate to ensure it meets the requirements for the bright trim strip. At this time, the support block is in the reset state under the action of the elastic component. The T-shaped rubber head cooperates with the groove of the support block to achieve limit and prevent the support block from colliding. Place the license plate frame on the pads on top of the two sets of support blocks, and start the counter-push cylinder of the clamping component. The counter-push cylinder drives the clamping plate to be guided along the guide rod. The clamping plates move relative to each other, clamping and fixing the two sides of the license plate frame to ensure the stability of the license plate frame position during the pressing process. Place the bright trim strip in the upper edge of the license plate frame for the bonding position through the external feeding group. Start the lower push cylinder of the pressing component. The lower push cylinder pushes the mounting plate to move downward along the column. The mounting plate drives the pressure plate to move downward synchronously. During the downward movement, the guide post at the bottom of the pressure plate and the first buffer are inserted into the first guide cylinder of the slide plate and the second guide cylinder of the support block, respectively, to ensure accurate pressing positioning. The pressure plate then presses the bright trim strip onto the upper edge of the license plate frame. When the first buffer contacts the second guide cylinder, it absorbs the impact force of the pressing, preventing damage to the workpiece. After pressing, the lower top cylinder drives the pressure plate to move upward and reset, while the push cylinder drives the clamping plate to retract and release the license plate frame. The push cylinder of the push assembly is activated, which drives the push plate to move. The push plate moves the connecting plate, protrusion, and push block synchronously through the connecting rod. The protrusion extends between the two sets of support blocks, using the slope of the opposite side of the support blocks to open the two sets of support blocks, separating the license plate frame from the rubber pad block and preventing adhesion. At the same time, the push block pushes the finished license plate frame to move outward of the slide plate, realizing automatic unloading. During the opening process of the support block, the baffle on its back contacts the second buffer, limiting the opening range of the support block and buffering it. When the push cylinder retracts, the support block resets along the protrusion under the spring tension of the elastic assembly, and the T-shaped rubber head cooperates with the groove again to limit the position. The device returns to the initial state, waiting for the next processing cycle.
