[0002] With the continuous development of science and technology, cars have gradually entered every household and become an irreplaceable means of transportation. In the process of car manufacturing, the sensors and internal wiring clips used in car bumpers need to be glued inside the bumper. Currently, most car bumper parts are glued manually.

[0003] Most existing automotive bumper parts are glued manually. During the gluing process, the operator needs to manually support the parts. Since the glue takes time to adhere, the operator must maintain the same posture to hold the parts firmly and cannot move them during this process. This is very inconvenient. If the parts are accidentally moved, the glue will be affected, resulting in an unstable connection. Therefore, manual gluing is time-consuming and the unstable connection makes it easy to install the wrong position, which has certain limitations. Utility Model Content

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figures 1-5 As shown, this utility model provides a technical solution: a bumper parts bonding device, including a fixed top plate 1, with adsorption and fixing devices 2 fixedly connected to both sides of the lower end of the fixed top plate 1, and limiting grooves 3 extending through both ends of the surface of the fixed top plate 1. Limiting sliders 4 are slidably connected inside the limiting grooves 3 at both ends, and clamping devices 5 are fixedly provided at the lower ends of the limiting sliders 4 at both ends. A driving device 6 is provided at the upper end of the fixed top plate 1, and the driving device 6 is fixedly connected to the limiting sliders 4. An adhesive applicator 7 is provided at the center of the lower end of the fixed top plate 1, and an applicator head device 8 is fixedly connected to the lower end of the adhesive applicator 7.

[0020] During use, the top plate 1 is fixed to both sides of the area to be glued, allowing the overall structure to be fixed in place. This ensures that subsequent gluing and part bonding can be performed in a precise location. Once the top plate 1 is fixed, the gluing device 7 is pushed down. After it moves down, the coating head device 8 presses onto the bonding area to apply the glue. After gluing, the gluing device 7 resets. Then, the rotating drive device 6 moves the two limit sliders 4 closer together, which in turn drives the two clamping devices 5 to clamp the parts. After clamping, the parts are then released from the outside. The air supply system simultaneously supplies a fixed amount of air pressure to the clamping devices 5 on both sides, which can drive the clamped parts to move downwards and abut against the adhesive position. After a period of time, when the adhesive has fully exerted its effect, the limit slider 4 is driven to move to both sides to release the parts. The air supply cylinder is cut off and returns to its original position. At this time, the adsorption fixing device 2 is removed, and the bonding work is completed. This design method uses an adsorption support device, which will not damage the bumper. After fixing, the glue application and parts docking work can be completed. The whole is removed after the glue has been applied to both sides. There is no need for manual support to wait for the glue to solidify. The entire docking process is stable and will not shift, resulting in a good docking effect.

[0021] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the adsorption and fixing device 2 includes a threaded rod 201, a threaded sleeve 202, a pneumatic suction cup 203, and an air pipe interface 204. The lower end of the threaded rod 201 is threadedly fitted with the threaded sleeve 202, and the lower end of the threaded sleeve 202 is fixedly connected to the pneumatic suction cup 203. The side wall of the pneumatic suction cup 203 is provided with an air pipe interface 204 for connecting to an external air source.

[0022] The pneumatic suction cup 203 can be connected to an external air source, such as a common air pump, to perform negative pressure adsorption and fixation, which can avoid the problem of easily damaging the bumper by clamping. By using a threaded sleeve 202 threaded onto the outer surface of the threaded rod 201, the adsorption height can be adjusted by thread, which can adapt to non-planar bumper designs and has a wide range of applications.

[0023] As one implementation method in this embodiment, please refer to Figure 3 As shown, the clamping device 5 includes a lifting cylinder 501 and a clamping head 503. The lifting cylinder 501 is threadedly fixed to the lower end of the limiting slider 4. A cylinder interface 502 is provided on one side of the lifting cylinder 501 for communicating with an external air source. One end of the output shaft of the lifting cylinder 501 is fixedly connected to the clamping head 503. A clamping groove 504 is fixedly opened on the inner wall of the clamping head 503.

[0024] Here, the cylinder interface 502 provided on the side of the lifting cylinder 501 can be connected to an external air source to perform pneumatic lifting and drive the clamped parts to lift. The clamping head 503 provided at the lower end of the lifting cylinder 501 is rectangular and close to the center to avoid the influence of the central adhesive applicator 7 from not being able to clamp the parts.

[0025] As one implementation method in this embodiment, please refer to Figure 3 The drive device 6 includes two fixed ear plates 601, a lead screw 602, a dividing block 604 and two threaded connecting blocks 605. The two fixed ear plates 601 are fixedly connected to the upper two sides of the fixed top plate 1, and the dividing block 604 is fixedly connected to the upper center of the fixed top plate 1. The lead screw 602 is rotatably connected between the two fixed ear plates 601. The center of the lead screw 602 is rotatably connected to the dividing block 604, and the threads at both ends of the lead screw 602 are opposite.

[0026] A lead screw 602 is rotatably mounted between the fixed ear plates 601. The lead screw 602 is divided into two end faces by the dividing block 604, and the threads on the two end faces of the lead screw 602 are opposite.

[0027] As one implementation method in this embodiment, please refer to Figure 4 As shown, threaded connecting blocks 605 are threaded onto the outer surfaces of both ends of the lead screw 602. The threaded connecting blocks 605 at both ends are symmetrical to each other. The lower ends of the threaded connecting blocks 605 at both ends are fixedly connected to the limiting slider 4. A rotary knob 603 is fixedly connected to one end of the lead screw 602.

[0028] The lead screw 602 can be rotated by the rotary knob 603. After the lead screw 602 rotates, it can rotate with the threaded connecting blocks 605 at both ends. The threaded connecting blocks 605 are limited by the limiting slider 4 and can only slide. This allows the lead screw 602 to drive the threaded connecting blocks 605 to move in a threaded translation after rotation. Since the threads on the surface of the lead screw 602 are opposite, it can drive the threaded connecting blocks 605 at both ends to move closer or further away, thereby clamping or loosening the parts.

[0029] As one implementation method in this embodiment, please refer to Figure 4As shown, the glue application device 7 includes a glue cylinder 701, a fixing block 702, a telescopic shaft 703, a fixing seat 704, a return spring 705, a push plate 706, a push rod 707, and a protective rubber sleeve 708. The fixing seat 704 is fixedly connected to the center of the fixing top plate 1. The telescopic shaft 703 is fixedly connected to both sides of the lower end of the fixing seat 704. The fixing block 702 is fixedly connected to both sides of the lower part of the glue cylinder 701. One end of the telescopic shaft 703 is fixedly connected to the fixing block 702 to limit the glue cylinder 701 to only move up and down. The return spring 705 is sleeved on the outer surface of the telescopic shaft 703. One end of the return spring 705 is fixedly connected to the fixing seat 704, and the other end of the return spring 705 is fixedly connected to the fixing block 702.

[0030] The telescopic shaft 703 limits the glue cylinder 701 to only moving up and down. When the glue cylinder 701 descends to apply glue, it can stretch the return spring 705, causing the return spring 705 to undergo elastic deformation. After the glue application is completed, the glue cylinder 701 returns to its original position under the elastic action of the return spring 705, thus avoiding affecting the docking of subsequent parts.

[0031] As one implementation method in this embodiment, please refer to Figure 4 As shown, push plates 706 are fixedly connected to both sides of the upper end of the glue cylinder 701. Push rods 707 are fixedly connected to one end of the push plates 706 at both ends for pushing the glue cylinder 701 down to apply glue. Protective rubber sleeves 708 are sleeved on the outer surface of the push rods 707 to provide certain protection.

[0032] By manually pressing down on the push rod 707, the glue cylinder 701 can be pushed down to perform the glue application work. The protective rubber sleeve 708 on the surface of the push rod 707 makes it more comfortable to hold.

[0033] As one implementation method in this embodiment, please refer to Figure 5 As shown, the coating head device 8 includes a connecting pipe 801, an internal threaded groove 802, an adapter 803, internal threaded teeth 804, an adhesive flow box 805, and an adhesive sponge 806. The lower end of the connecting pipe 801 is fixedly provided with an internal threaded groove 802. The upper end of the inner wall of the adapter 803 is fixedly provided with internal threaded teeth 804 that mesh with the adapter 803. The lower end of the adapter 803 is connected to the adhesive flow box 805, and the lower end of the adhesive flow box 805 is fixedly connected to the adhesive sponge 806.

[0034] By using a threaded coating sponge head, the size of the 806 coating sponge can be changed according to the size of the bonding surface, avoiding excessive coating that affects the appearance. This design allows for the replacement of different sizes of coating sponges, and the coating brush head can be adjusted according to the size of the bonding surface, making it more convenient and applicable.

[0035] Working Principle: During use, the pneumatic suction cup 203 can be connected to an external air source, such as a common air pump, for negative pressure suction and fixation. This avoids the problem of easily damaging the bumper when clamped. The threaded sleeve 202 is threaded onto the outer surface of the threaded rod 201, allowing for adjustment of the suction height to accommodate non-planar bumper designs. After fixation, manually pressing down the push rod 707 lowers the glue cylinder 701 for glue application. When the glue cylinder 701 descends for glue application, it stretches the return spring 705, causing it to elastically deform. After glue application, releasing the spring allows the glue cylinder 701 to return to its original position, preventing interference with subsequent parts assembly. This is achieved by using the rotary knob 6. 03 The lead screw 602 can be rotated. After the lead screw 602 rotates, it can rotate with the threaded connecting blocks 605 at both ends. The threaded connecting blocks 605 are limited by the limiting slider 4 and can only slide. This allows the lead screw 602 to rotate and drive the threaded connecting blocks 605 to move in a threaded translation. The threads on the surface of the lead screw 602 are opposite, which can drive the threaded connecting blocks 605 at both ends to move closer or further away, thereby clamping or loosening the parts. After the parts are clamped and fixed, a certain amount of air pressure is simultaneously introduced into the clamping devices 5 on both sides through the external air source system. This can drive the clamped parts to move downward and abut against the adhesive position. After a period of time, when the adhesive has fully played its role, the limiting slider 4 is driven to move to both sides to release the parts. The air source is cut off and the cylinder returns to its original position. At this time, the adsorption and fixing device 2 is removed to complete the bonding work.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
