Description

Technical Field

[0001] The utility model relates to the field of automobile headlamp production, and particularly relates to a through-type front headlamp assembly device with a fixing structure. Background Technique

[0002] The through-type front headlamp assembly device involves technologies and designs in multiple aspects. Generally, it includes a numerical control frame, which serves as the basic frame of the entire assembly device, providing a stable support and operation platform; a robotic arm, which is usually located on the top of the numerical control frame and is used to grab, move, and assemble headlamp components; and a positioning mechanism, through which the headlamp is fixed. The general assembly principle is as follows: Place the headlamp to be assembled between the two clamping plates of the positioning mechanism, and adjust the position of the clamping plates through the positioning mechanism to ensure that the headlamp is firmly fixed; the robotic arm uses existing technologies (such as visual recognition, precise control, etc.) to perform assembly operations on the headlamp, such as installing a light-emitting unit module, a high-low beam integrated module, etc.

[0003] However, in the prior art, the two clamping plates of the positioning mechanism generally need to be operated one by one, which is time-consuming and laborious. Moreover, after clamping, due to the force on the headlamp during the assembly process, the clamping plates are frequently stressed, which easily causes the headlamp to loosen, thereby affecting the assembly accuracy. In addition, the existing positioning mechanisms only clamp and position the workpiece from the side, ignoring the positioning in the vertical direction, and sometimes the workpiece is prone to vertical deviation.

[0004] Therefore, it is very necessary to propose a through-type front headlamp assembly device with a fixing structure to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a through-type front headlamp assembly device with a fixing structure, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A through-type front headlight assembly device with a fixed structure, comprising an assembly table, a positioning seat arranged at one end of the top of the assembly table, and an assembly manipulator arranged at the top of the assembly table corresponding to the positioning seat. A positioning groove adapted to the shape of the headlight and used for placing the headlight is arranged at the top of the positioning seat. A lateral positioning mechanism is arranged on the positioning seat. The lateral positioning mechanism comprises a concave cavity arranged on the outer periphery of the inner side of the positioning groove. A bidirectional lead screw is rotatably connected to the lower end of the inner cavity of the concave cavity. One end of the bidirectional lead screw extends to the outside of the positioning seat and is provided with a handwheel for screwing the bidirectional lead screw. Traction arms are symmetrically and threadedly connected to the outer sides of both ends of the bidirectional lead screw. A clamping block corresponding to the lower end of the inner side of the positioning groove and used for clamping the side of the headlight is fixedly arranged at the upper end of the traction arm. A groove is arranged on one side of the clamping block close to the positioning groove. A pressing block used for pressing against the side of the headlight is movably connected to the groove. A first spring is arranged between the pressing block and the inner wall of the groove, and the end of the pressing block far from the first spring protrudes from the end of the clamping block under the initial state of the first spring.

[0008] Preferably, the ends of both the pressing block and the clamping block are adapted to the shape of the side wall of the headlight.

[0009] Preferably, a first through groove communicating with the concave cavity and used for the clamping block to enter and exit is arranged at the lower end of the inner side of the positioning groove.

[0010] Preferably, a longitudinal positioning mechanism is further included. The longitudinal positioning mechanism comprises vertical rods fixedly arranged at the ends of the tops of the two clamping blocks far away from each other. Moving frames are symmetrically and movably arranged on the opposite sides of the two vertical rods. A second spring is arranged between the moving frame and the vertical rod. A pressing block used for pressing the top of the headlight is vertically and movably connected to the moving frame. A traction block is fixedly arranged at one end of the bottom of the pressing block close to the moving frame. An inclined groove is arranged on the traction block. A driving arm corresponding to the traction block is arranged on the side of the vertical rod close to the moving frame. A roller corresponding to the inclined groove is rotatably connected to the end of the driving arm far away from the vertical rod, and the roller is movably connected to the inner side of the roller and is configured to displace the traction block downward when the distance between the moving frame and the vertical rod is reduced.

[0011] Preferably, a second through groove communicating with the concave cavity and used for the pressing block to enter and exit is arranged at the upper end of the inner side of the positioning groove, and the height of the inner cavity of the second through groove is greater than the thickness of the pressing block.

[0012] Preferably, a guide groove is arranged on one side of the moving frame. One end of the pressing block is slidably connected to the inner side of the guide groove. A guide post is vertically fixedly arranged on the inner side of the guide groove, and the pressing block is movably connected to the guide post through a guide sleeve.

[0013] Compared with the prior art, the utility model provides a through-type front headlight assembly device with a fixed structure, which has the following beneficial effects:

[0014] The through-type headlight assembly device with a fixed structure can simultaneously clamp both sides of the headlight through the set lateral positioning mechanism with one operation, and there is always a reverse acting force after clamping, which can also increase the stability of the headlight, reduce the possibility of loosening, and is convenient to operate. Based on the above, through the linkage setting of the longitudinal positioning mechanism and the lateral positioning mechanism, the headlight can be limited at the bottom and top while the lateral positioning is being clamped, ensuring the longitudinal stability of the headlight and facilitating the assembly process, thereby improving the assembly accuracy.

A positioning groove 4 adapted to the shape of the headlight and used for placing the headlight is provided at the top of the positioning seat 3. A lateral positioning mechanism is provided on the positioning seat 3. The lateral positioning mechanism includes a concave cavity 5 provided on the inner periphery of the inner side of the positioning groove 4. A bidirectional lead screw 6 is rotatably connected to the lower end of the inner cavity of the concave cavity 5. One end of the bidirectional lead screw 6 extends to the outside of the positioning seat 3 and is provided with a handwheel 7 for screwing the bidirectional lead screw 6. Clamping arms 8 are symmetrically threadedly connected to the outer sides of both ends of the bidirectional lead screw 6. A clamping block 9 corresponding to the lower end of the inner side of the positioning groove 4 and used for clamping the side of the headlight is fixedly provided at the upper end of the clamping arm 8. A groove 12 is provided on the side of the clamping block 9 close to the positioning groove 4. A pressing block 10 for pressing against the side of the headlight is movably connected to the groove 12. The ends of the pressing block 10 and the clamping block 9 are both adapted to the side wall shape of the headlight. A first spring 11 is provided between the pressing block 10 and the inner wall of the groove 12, and in the initial state of the first spring 11, the end of the pressing block 10 away from the first spring 11 protrudes from the end of the clamping block 9. A first through groove 21 communicating with the concave cavity 5 and used for the clamping block 9 to enter and exit is provided at the lower end of the inner side of the positioning groove 4.

[0022] Furthermore, it also includes a longitudinal positioning mechanism. The longitudinal positioning mechanism includes vertical rods 14 fixedly provided at the opposite ends of the tops of the two clamping blocks 9 away from each other. Moving frames 15 are symmetrically and movably provided on the opposite sides of the two vertical rods 14. A second spring 18 is provided between the moving frames 15 and the vertical rods 14. A pressing block 13 for pressing the top of the headlight is vertically movably connected to the moving frames 15. A traction block 19 is fixedly provided at one end of the bottom of the pressing block 13 close to the moving frames 15. An inclined groove 23 is provided obliquely on the traction block 19. A driving arm 20 corresponding to the traction block 19 is provided on the side of the vertical rod 14 close to the moving frames 15. A roller 24 corresponding to the inclined groove 23 is rotatably connected to the end of the driving arm 20 away from the vertical rod 14, and the roller 24 is movably connected to the inside of the roller 24 and is configured to displace the traction block 19 downward when the distance between the moving frames 15 and the vertical rods 14 decreases. A second through groove 22 communicating with the concave cavity 5 and used for the pressing block 13 to enter and exit is provided at the upper end of the inner side of the positioning groove 4, and the height of the inner cavity of the second through groove 22 is greater than the thickness of the pressing block 13.

[0023] In order to guide the pressing block 13, a guide groove 17 is provided on one side of the moving frames 15. One end of the pressing block 13 is slidably connected to the inside of the guide groove 17. A guide post 16 is vertically fixedly provided inside the guide groove 17, and the pressing block 13 is movably connected to the guide post 16 through a guide sleeve.

[0024] It should be noted that the present utility model is a through-type headlight assembly device with a fixed structure. When in use, the headlight is placed in the positioning groove 4 at the top of the positioning seat 3, so that the bottom of the headlight is in contact with the inner wall of the positioning groove 4. After adjusting the position of the headlight, the two-way lead screw 6 can be driven to rotate by the handwheel 7. The two-way lead screw 6 drives the displacement of the two traction arms 8, the traction arm 8 drives the displacement of the clamping block 9, and the clamping block 9 drives the pressing block 10 to contact the side wall of the headlight through the first through groove 21. Then the pressing block 10 remains stationary, and the clamping block 9 continues to displace. The first spring 11 is compressed, and the first spring 11 generates a reverse acting force on the pressing block 10. The pressing block 10 acts on the headlight. Moreover, when the clamping block 9 displaces, it will also drive the vertical rod 14 and the moving frame 15 to displace. When the moving frame 15 drives the pressing block 13 to displace, the pressing block 13 enters the upper end of the positioning groove 4 through the second through groove 22. When the moving frame 15 contacts the inner wall of the concave cavity 5, it is blocked. Subsequently, only the vertical rod 14 follows the displacement of the clamping block 9, and then the second spring 18 is compressed. At this time, the distance between the vertical rod 14 and the moving frame 15 is reduced. Under the action of the inclined groove 23 and the roller 24, the traction block 19 drives the pressing block 13 to displace downward. When the clamping block 9 tightly clamps the side wall of the headlight, the bottom of the pressing block 13 just fits and presses the corresponding position at the top of the headlight. This rotating shaft can realize the simultaneous displacement of the clamping structures in two directions through the operation on one side, which can not only realize the clamping on the side, but also ensure the longitudinal positioning. Moreover, the pressing block 13 is initially hidden in the concave cavity 5 and will not affect the taking and placing of the headlight. When positioning, the pressing block 13 first moves out and then moves down to press, with a compact structure and convenient operation.
