The inner wall of the placement part 62 and the inner walls of the two placement plates 61 are coplanar with the three inner walls of the bottom component 57. The radar bracket between the two placement plates 61 can be moved into the bottom component 57.

[0078] The side of the placement plate 61 is provided with a temporary opening 68, and a rotating shaft 69 is rotatably arranged in the temporary opening 68. A temporary plate 70 is fixedly arranged on the rotating shaft 69, and one end of the rotating shaft 69 is located on the outside of the placement plate 61.

[0079] The receiving member 29 has a receiving opening 71 on its side, which is located above the receiving frame 56. In the standby state, one end of the temporary plate 70 is located between the two placement plates 61, and the inner end of the temporary plate 70 supports the bottom of the mounting plate a located at the bottom. After the temporary plate 70 is moved into the receiving opening 71, the placement plate 61 is moved downwards. The inner wall of the receiving opening 71 drives the outer end of the temporary plate 70 to rotate upwards until the temporary plate 70 is received into the temporary opening 68, wherein:

[0080] A fifth elastic element 72, preferably a torsion spring, is provided between the rotating shaft 69 and the placement part 62. When no radar bracket is placed, the fifth elastic element 72 causes the inner end of the temporary plate 70 to be horizontal or tilted upward. After the radar bracket is placed, the pressure between the radars causes the temporary plate 70 to rotate to a horizontal state. Then, after being installed in the receiving part 29, the temporary plate 70 rotates to be completely received in the temporary opening 68, so that the radar bracket can directly pass over the temporary plate 70.

[0081] The integrated equipment for punching and installing radar brackets on bumpers provided by this invention involves manually placing the bumper upside down onto the support beam 2 and support part 3 during the processing of the bumper. The shape formed by the support beam 2 and support part 3 is adapted to the inner wall shape of the bumper. At the same time, a negative pressure suction cup can be pre-embedded in the support part 3. After the bumper is fitted and fastened onto the support part 3, the negative pressure suction cup generates negative pressure, which can make the bumper stably connected to the support part 3 and support beam 2.

[0082] Then, the first drive mechanism drives the bumper to move, causing the inner side of the bumper to abut the top of the punching cylinder 5. The first power component 6 drives the punching column 7 to move downward, punching a hole in the bumper for mounting the radar bracket. The excess material punched out is discharged outward through the punching cylinder 5. The support part 3 is spaced out, and the punching cylinder 5, ultrasonic welding head 10, etc., do not interact with the support beam 2 and the support part 3.

[0083] After punching is completed, the first drive mechanism moves the bumper to a position above the welding frame 8 and stops, maintaining the bumper's position. Then, the second drive mechanism drives the pressing plate 14 downwards and abuts against the top of the bumper; subsequently, the welding seat 9 rises, causing the mounting plate a of the radar bracket on the support column 12 to fit against the lower side of the bumper. The welding seat 9 continues to rise, compressing the first elastic element 13 until the ultrasonic welding head 10 abuts against the lower side of the mounting plate a and is activated. Thus, the mounting plate a can be fixed to the bumper via ultrasonic welding. The ultrasonic welding head 10 is a commercially available product, preferably an ultrasonic piercing welding head. It should also be understood that other supporting structures, such as the ultrasonic generator, are existing technologies and will not be elaborated upon here. Simultaneously, there are several welding frames 8 and punching frames 4, preferably four, allowing radar brackets to be installed at the ends and sides of the bumper.

[0084] In the actual production process, workers first need to place several radar brackets in the structure formed by the placement plate 61 and the placement part 62 outside the equipment, so that the placement plate 61 with radar brackets can be directly installed into the receiving part 29 and the empty placement plate 61 can be taken out, thereby improving production efficiency. The edges of the mounting plate a of the placed radar bracket are all attached to the placement plate 61 and the placement part 62, while the bottom of the mounting cylinder b at the bottom abuts against the temporary plate 70. The placement plate 61 can be placed horizontally when it is outside the housing 29, thus requiring less elasticity from the fifth elastic member 72. After all the radar brackets inside the housing 29 have been used, first, a finger or other tool (such as a screwdriver) is passed through the reset groove 63 (the status of the radar brackets inside can also be observed through the reset groove 63, such as the number, angle, and whether they have descended smoothly). Then, the counterweight 58 (which has a groove on its outer side for inserting a finger or tool) is raised, and the counterweight 58 is separated from the placement plate 61 and then attached to the top of the housing 29 by the positioning magnet 54. At this point, simply raise the placement plate 61 to remove the placement column 67 from the housing 56, and then the empty placement plate 61 and placement part 62 can be removed from the housing 29 horizontally outward.

[0085] Afterwards, the worker manually moves the placement plate 61, which is filled with radar brackets, to the receiving part 29. The placement plate 61 is then adjusted to be vertical (the placement plate 61 in the middle of the bumper) or slightly tilted (the placement plate 61 at the edge of the bumper). The placement plate 61 is then inserted into the receiving part 29, and the outer end of the temporary plate 70 is inserted into the receiving opening 71. The placement plate 61 is then moved downward along the inner wall of the receiving part 29 until the bottom of the placement plate 61 and the placement part 62 touches the top of the bottom part 57. At the same time, the placement column 67 is also engaged in the opening formed by the receiving frame 56 and the receiving part 29. During the descent, the bottom of the receiving opening 71 touches the outer side of the temporary plate 70, causing the outer side of the temporary plate 70 to swing upward. This causes the inner side to swing downward, thus eliminating the support for the radar bracket on the inner side and allowing the radar bracket to move smoothly downward into the bottom part 57. The inner walls of the placement plate 61 and the placement part 62 are coplanar with the inner wall of the base component 57. Thus, the periphery of each mounting plate a is movably fitted against the inner wall of the placement plate 61, the placement part 62, or the base component 57. Simultaneously, the inner side of the mounting plate a is movably fitted against the inner wall of the receiving member 29, allowing each radar bracket to move smoothly downwards. The mounting plate a has a certain thickness, which helps maintain the angular stability of the radar bracket during downward movement.

[0086] After the placement plate 61 is properly positioned, the counterweight 58 and positioning magnet 54 are manually separated downwards, allowing the counterweight 58 to move past the two anti-detachment plates 64. The counterweight part 59 then moves through the through-hole 65 and engages in the engagement slot 66. This allows the counterweight 58 to apply downward pressure to the radar bracket, facilitating its downward movement. Simultaneously, the presence of the counterweight 58 prevents the placement plate 61 from rotating outwards towards the receiving part 29, ensuring the stability of the connection between the placement plate 61 and the receiving part 29. Furthermore, the counterweight 58 allows the radar bracket to move downwards relatively smoothly, ensuring that even with small gaps between the mounting plate a and the inner walls of the placement plate 61, placement part 62, and bottom part 57, the radar bracket can still descend smoothly, further guaranteeing its angular stability. Since the radar placement into the placement plate 61 can be performed simultaneously with punching and welding processes, operational efficiency is improved. Moreover, the subsequent automatic mounting of the radar bracket onto the support column 12 further enhances production efficiency.

[0087] After the worker attaches the bumper to the support part 3 and the support beam 2, it is held in place by a suction cup. Then, the cylinder on the support seat 16 (or other power structure, such as an electric actuator or hydraulic cylinder, hereinafter referred to as a cylinder) drives the lifting plate 19 to move upward, thereby raising the support beam 2 and the bumper, making the bumper higher than the punching cylinder 5. Then, the cylinder drives the support seat 16 to move towards the punching cylinder 5, and after the bumper is higher than the punching cylinder 5, the lifting plate 19 lowers the bumper, so that the inner side of the bumper abuts against the top of the punching cylinder 5. Then, the first power component 6 drives the punching column 7 to move downward, which also causes the clamping frame 21 to move downward. Before the clamping plate 22 abuts against the top of the bumper, the bottom of the clamping plate 22 is higher than the punching column 7. At this time, the clamping plate 22 and the clamping frame 21 are connected by the second elastic element 23. As the punching column 7 continues to descend, the clamping plate 22 first contacts the top of the bumper until it presses the bumper firmly against the punching cylinder 5. Then, the punching column 7 contacts the top of the bumper and punches the portion of the bumper that is being pressed down. The punching column 7 pushes the punched disc into the punching cylinder 5, thus achieving a better punching effect. Then, the punching column 7, clamping frame 21, etc., rise, and then the lifting plate 19 raises the height of the bumper and moves outward to above the welding frame 8. The lifting plate 19 descends a certain distance and then stops (preferably stopping in place, but it can also stop in place), waiting for welding.

[0088] The support base 16 and the first track 15, the lifting plate 19 and the second track 18, and the clamping frame 21 and the third track 20 are all connected by fastening. For example, the first track 15, the second track 18, and the third track 20 are dovetail-shaped, and the support base 16, the lifting plate 19, and the clamping frame 21 have dovetail grooves.

[0089] During welding, the second power component 25 (preferably a cylinder) first lowers the pressing plate 14, pressing the bumper firmly against the support part 3. Then, the welding seat 9 is driven upwards by the cylinder, and the support column 12 first causes the mounting plate a to fit against the inner side of the bumper. The mounting cylinder b, which is higher than the mounting plate a, is inserted into a punched hole in the bumper. This insertion not only improves the positional stability of the radar bracket and subsequent radar, but also allows the outer end of the subsequent radar to be coplanar with the outer end of the bumper, improving aesthetics and reducing stains.

[0090] After the mounting plate a is attached to the inside of the bumper, the welding seat 9 remains raised, causing the first elastic element 13 (which has a large elastic coefficient, ensuring that the mounting plate a is stably attached to the bumper and providing sufficient support when attaching a new radar bracket) to undergo elastic deformation until the ultrasonic welding head 10 contacts the lower side of the mounting plate a and applies an upward force, until the welding is finally completed and the welding seat 9 moves downward. During the downward movement of the welding seat 9, the ultrasonic welding head 10 separates from the mounting plate a first, and then the support column 12 separates from the mounting cylinder b. Thus, during the initial separation process, the first elastic element 13 still applies pressure to the mounting cylinder b upward through the support column 12, preventing the mounting cylinder b from sticking to the ultrasonic welding head 10 and separating the mounting plate a from the bumper. The support column 12 has a thinner diameter at the top and a thicker diameter at the bottom. The thinner diameter part is used to fit the mounting cylinder b, while the thicker diameter part moves to fit against the inner wall of the support cylinder 11, and the top of the thicker part supports the mounting cylinder b.

[0091] After welding is completed, the pressing plate 14 is raised, and the worker directly removes the bumper from the support part 3 (the negative pressure of the negative pressure suction cup disappears) and places the new bumper directly. Then the bumper is sent to the punching frame 4 for punching.

[0092] During the lifting process of the pressing plate 14, the pushing arm 37 also rises and acts on the lower side of the pushing frame 39. Since the pushing frame 39 is inclined, it can drive the pushing arm 37 to move towards the punching frame 4. At the same time, the pushing member 36 and the temporary support member 51 move towards the punching frame 4, pushing the bottom radar bracket of the receiving member 29 towards the unloading groove 31. During this pushing process, the side of the radar bracket is simultaneously pushed by the pushing member 36 and the side wall of the temporary support groove 52, that is, both the top and bottom of the radar bracket are pushed, so that the radar bracket can be stably pushed into the unloading groove 31. Moreover, after the bottom radar bracket is driven to move by the pushing member 36, the top of the pushing member 36 can limit the radar bracket above, thus preventing the radar bracket above from falling naturally.

[0093] During the process of pushing the radar bracket, the side of the top of the mounting cylinder b will first come into contact with the lower part of the driving slope 48, causing the unlocking column 45 and the unlocking block 46 to move upward. At the same time, the unlocking block 46 drives the two third limiting parts 43 to move outward through the unlocking slope 47, and the two limiting plates 40 move outward. After the mounting cylinder b passes the driving ramp 48, the auxiliary ramp 49 acts on the inner side of the mounting cylinder b and accelerates the inward movement of the mounting cylinder b (or the auxiliary ramp 49 does not play an accelerating role, but only shortens the length of the driving ramp 48, in which case the auxiliary ramp 49 is vertical); until finally the radar bracket is pushed to completely fit against the inner wall of the feeding trough 31, at this time the two fourth elastic elements 44 make the two third limiting parts 43 approach each other, and at the same time, under the action of their own gravity, the unlocking block 46 and the unlocking post 45 move downward. At this time, the back of the unlocking post 45 abuts against the inner wall of the mounting cylinder b, and the limiting plate 40 abuts against the lower side of the mounting plate a, ensuring that the radar bracket has sufficient positional stability.

[0094] During the process of the radar bracket being pushed into the feeding trough 31, the limiting plate 40 does not support the mounting plate a, but the bottom inner wall of the auxiliary trough 53 supports the bottom of the mounting cylinder b. This ensures that the radar bracket enters the feeding trough 31 stably without falling down, until the limiting plate 40 finally resets and supports the mounting plate a. The top of the mounting cylinder b, located in the feeding trough 31, abuts against the inner wall of the feeding trough 31. The outer sides of both ends of the mounting plate a are attached to the inner wall of the feeding trough 31, and the lower sides of both ends are supported by the limiting plate 40. The side of the mounting plate a closer to the punching frame 4 abuts against the inner wall of the feeding trough 31, and the side away from the punching frame 4 abuts against the radar bracket in the receiving member 29. The tops of the opposing ends of the two limiting plates 40 are inclined, chamfered, or rounded, thus facilitating the smooth movement of the mounting plate a to its lower side.

[0095] Then, after the receiving part 29 moves down a short distance, under the pulling force of the third elastic part 38, the pushing part 36, the pushing arm 37, and the temporary support part 51 all move outward until the pushing arm 37 touches the end of the pushing opening 35. At this time, the upper radar bracket moves downward under its own weight and the pressure of the counterweight 58, and the bottom radar bracket can limit the radar bracket in the feeding trough 31. Depending on the actual situation, the top and bottom of both sides of the mounting plate a can be designed as chamfered or rounded, so that the two mounting plates a can easily abut against each other.

[0096] As the receiving member 29 continues to descend, there is no bumper below the pressing plate 14, allowing the radar bracket in the feeding slot 31 to be fitted onto the support column 12 (the ultrasonic welding head 10 can pass through the clearance hole 33 depending on the actual situation). As the receiving member 29 continues to descend, the bottom of the unlocking column 45 will contact the top of the support column 12, and the unlocking column 45 will move upwards under the action of the support column 12 (during this process, the support column 12 also moves downwards, but the elastic force of the first elastic member 13 is greater than that of the fourth elastic member 44, preventing the ultrasonic welding head 10 from acting on the mounting plate a). Simultaneously, the unlocking block 46 drives the two third limiting parts 43, the second limiting part 42, the first limiting part 41, and the limiting plate 40 to move outwards via the unlocking ramp 47, separating the limiting plate 40 from the mounting plate a. The pressing plate 14 then continues to descend until the top of the support column 12 finally contacts the top of the feeding slot 31. Depending on the actual situation, the welding seat 9 can be raised or not raised during this process.

[0097] After the radar bracket is fitted onto the support column 12, the receiving part 29 rises. At this time, there is a certain distance between the limiting plate 40 and the mounting plate a, and the mounting plate a is relatively thin. Therefore, even if the fourth elastic element 44 causes both limiting plates 40 to move inward toward the material feeding groove 31, the limiting plates 40 will only reset after passing the mounting plate a, thus completing the automatic fitting of the radar bracket. During this automatic fitting process, punching is in progress, which makes the overall production efficiency higher.

[0098] Although the automatic installation process of the radar bracket involves several steps, in practice it simply involves raising the receiving component 29 to a designated height and then lowering it back to that height. Simultaneously, the depth to which the limiting plate 40 extends into the unloading groove 31 is minimal, only needing to prevent the mounting plate a from slipping. Secondly, after the radar bracket is automatically fitted onto the support column 12, the receiving component 29 rises to a certain height, but the pushing arm 37 does not need to act on the pushing frame 39. Also, if the welding seat 9 was previously raised, it needs to be lowered to await welding. During welding, because the bottom of the temporary support 51 is at the same height as or higher than the bottom of the pressing plate 14, the function of the pressing plate 14 can be achieved normally.

[0099] In another embodiment, such as Figure 22As shown, the free end of the rotating shaft 69 is provided with a vertical shaft 73 perpendicular to the rotating shaft 69, and a sixth elastic element 74 is provided between the free ends of the two vertical shafts 73. In the standby state, the free ends of the two vertical shafts 73 are connected through the sixth elastic element 74, so that the inner end of the temporary plate 70 is horizontal or tilted upward. After the radar bracket is placed, the temporary plate 70 is rotated to a horizontal state. Subsequently, after the temporary plate 70 is driven by the receiving port 71, it can be completely received into the temporary port 68. At the same time, the sixth elastic element 74 also undergoes corresponding deformation and is in a compressed state.
