[0025] The technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0026] Combination Figure 1-Figure 5 As shown, the present invention discloses an automobile seat belt latch bolt assembly machine, comprising a frame 10, a washer moving mechanism, a pressing mechanism 11, an upward movement mechanism 12 and two bolt assembly mechanisms 13 arranged on the frame 10. Through the cooperation between various components, the fixed installation of the lock head 14, the washer and the bolt 15 is realized, and the automation of the installation is realized.

[0027] The washer moving mechanism includes a vibration plate 16, a clamping mechanism 17 and a first cylinder 18. A toothed washer 19 is placed in the vibration plate 16. The vibration plate 16 is connected to a washer slideway 20, so that the toothed washer 19 moves to the end of the washer slideway 20, thereby realizing the subsequent operation of the clamping mechanism 17. The vibration plate 16 is also connected to a loading box 21. When loading, the toothed washer 19 is poured into the loading box 21 and enters the vibration plate 16 through the opening of the loading box 21. Furthermore, the loading box 21 is set as needed. When the entire device is small, the loading box 21 may not be set, and the toothed washer 19 can be directly poured into the vibration plate 16 to save space.

[0028] The clamp mechanism 17 includes a moving clamp 22 and a third cylinder 23. The third cylinder 23 drives the moving clamp 22 to grasp the toothed washer 19 downward and then return to the original position upward. The first cylinder 18 is provided with a slide rail 24. The moving clamp 22 is slidably connected to the slide rail 24. After the moving clamp 22 grasps the toothed washer 19, it moves horizontally on the slide rail 24 of the first cylinder 18 to deliver the toothed washer 19 to the pressing mechanism 11. After the delivery is completed, it returns to the original position along the original path to perform the next operation, and the action is repeated.

[0029] The pressing mechanism 11 includes a dispensing controller 25, a power source 26 and a pressure device. The dispensing controller 25 is fixedly mounted on the frame 10 and is arranged on the upper outer surface of the frame 10, so that the operator can adjust and control it. By setting different times or pressures, the pressure device can achieve different downward pressures. The pressure device includes a displacement sensor 27, a pressure column 28 and a second cylinder 29. A connecting rod 30 is also arranged in the pressure column 28. The second cylinder 29 drives the connecting rod 30 to move axially, and then presses with the bolt 15. While pressing, the displacement sensor 27 measures the height of the toothed washer 19 and the bolt 15, so as to detect whether the installation position of the bolt 15 and the toothed washer 19 is correct. If it is correct, the next step of operation will be carried out, otherwise the work will be stopped.

[0030] A mounting plate 31 is provided between the pressure device and the power source 26, and the power source 26 and the pressure device are fixedly mounted on the mounting plate 31. The power source 26 is also connected to a lower pressing plate 32, and the lower pressing plate 32 is in contact with the pressure column 28. When the power source 26 moves, the lower pressing plate 32 is driven to move, thereby driving the pressure column 28 to move, thereby realizing the installation of the automobile seat belt latch.

[0031] The upward movement mechanism 12 includes a moving column 33 and a fourth cylinder 34. The fourth cylinder 34 drives the moving column 33 to move upward to contact the bolt assembly mechanism 13, and has a large upward force to support the bolt assembly mechanism 13 to achieve better installation of other steps.

[0032] The bolt assembly mechanism 13 is fixedly mounted on a disc 35, and the disc 35 is fixedly mounted on the frame 10, and the lower side thereof is provided with the upward movement mechanism 12 and the servo motor 36, and the servo motor 36 is used to drive the disc 35 to rotate. The frame 10 is provided with a button 37 for controlling the servo motor 36. After the bolt 15 and the lock head 14 are placed, the button 37 is pressed to make the servo motor 36 drive the disc 35 to rotate, and the bolt assembly mechanism 13 is rotated to perform the next step. After the complete installation is completed and the previous bolt assembly is completed, the next installation is performed, and the fixed installation of the automobile seat belt latch bolt is realized by repeating the cycle. The direction of rotation of the disc 35 is set according to the actual situation. If it rotates clockwise at the beginning, it rotates counterclockwise at the end; if it rotates counterclockwise at the beginning, it rotates clockwise at the end. Optionally, a wire take-up box 38 is also provided on the disc 35 to integrate the wiring, which is convenient for the influence caused by the disorderly placement of the wiring during the assembly process.

[0033] The bolt assembly mechanism 113 includes a fixing plate 39, a boss 40, a bolt mounting assembly 41, a cylinder assembly 42 and a pushing assembly 43. The fixing plate 39 is fixedly mounted on the disc 35. The bolt mounting assembly 41 extends downward to form a top ring 44. When the upward movement mechanism 12 moves upward, it contacts the top ring 44 and continues to move upward until it moves to the correct position.

[0034] Optionally, the frame 10 is also provided with an NG box 45, a barcode reader 46 and a display screen 47. The NG box 45 is used to place incorrect models of lock heads 14, bolts 15 and toothed washers 19. The barcode reader 46 is used to read the QR code on the lock head 14. If it does not match, it will be placed in the NG box 45. The display screen 47 is used to display data during the operation process, which is convenient for the operator to observe in real time.

[0035] Optionally, the frame 10 is also provided with an oil filling mechanism, which includes an oil reservoir 48, an oil filling valve 49 and an oil filling body 50. Before installing the lock 14, the lock 14 is first placed on the oil filling body 50 for oil filling. The oil filling valve 49 will monitor whether there is oil on the oil filling body 50. If there is no oil, oil will be drawn from the oil reservoir 48 column and sent to the oil filling body 50.

[0036] The working principle of the present invention is as follows: first, the lock head 14, the bolt 15 and other components are placed in the bolt assembly mechanism 13, and the combination after placement is preliminarily fixed, and then the button 37 is pressed to rotate the bolt assembly mechanism 13 placed outside to the inside, and then the vibration plate 16 sends the toothed washer to the end of the washer slide 20, and the toothed washer 19 is placed on the bolt 15 by moving the clamping claw 22, and finally the power source 26 drives the pressure column 28 to press downward to complete the installation of the car seat belt latch, and after the installation is completed, the disk 35 is rotated by pressing the button 37 while waiting for the next installation to realize the removal of the car seat belt latch.
