Gantry group slide rails 6 are provided on both sides of the frame 1. The front gantry group 2 and the rear gantry group 3 both slide on the gantry group slide rails 6. The riveting mechanism 4 slides horizontally on the front gantry group 2, and the riveting mechanism 5 slides horizontally on the rear gantry group 3. The rivets are transported to the front gantry group 2, and the riveting mechanism 4 accurately places the rivets into the holes of the battery shell. The battery shell is moved to the rear section on the frame 1, and the rivet is pulled and fixed into shape by the riveting mechanism 5 on the rear gantry group 3.

[0027] A conveying square tube 30 is installed on both sides of the interior of the frame 1. A conveying roller 31 is rotatably connected to the conveying square tube 30. A lifting and positioning cylinder 32 is fixed on the conveying square tube 30. The driving end of the lifting and positioning cylinder 32 is vertically upward. During the rotation of the conveying roller 31, the battery shell is driven to move backward until the battery shell stops under the control of the lifting and positioning cylinder 32.

[0028] A conveying slide 33 is fixed on the frame 1 along the horizontal direction. The conveying square tube 30 on one side is fixedly connected to the frame 1, and the conveying square tube 30 on the other side slides on the conveying slide 33. According to the width of the battery shell, the distance between the conveying square tubes 30 on both sides can be adjusted, thereby changing the position of the conveying roller 31 serving as the conveying structure.

[0029] Gantry group racks 34 are fixed on both sides of the frame 1 along the front and rear directions, and front and rear motors 35 are provided on the front and rear motors 35. The driving ends of the front and rear motors 35 are connected with front and rear gears, which are engaged with the gantry group racks 34 for transmission. Left and right motors 36 and left and right slide rails 37 are installed on the front and rear gantry groups 2 and 3, and the driving ends of the left and right motors 36 are connected with left and right screws 38. The riveting mechanism 4 is threadedly connected to the left and right screws 38 through the nut seat and makes the riveting mechanism 4 slide on the left and right slide rails 37 of the front gantry group 2. The riveting mechanism 5 is threadedly connected to the left and right screws 38 through the nut seat and makes the riveting mechanism 4 slide on the left and right slide rails 37 of the rear gantry group 3.

[0030] The front and rear motors 35 provide power, and the front and rear gears cooperate with the gantry group rack 34 to enable the front gantry group 2 and the rear gantry group 3 to move forward and backward. In the left and right directions, the left and right motors 36 provide power, and the left and right screws 38 drive the rivet mechanism 4 to slide on the front gantry group 2 under the action of the left and right slide rails 37, and also drive the rivet pulling mechanism 5 to slide on the rear gantry group 3. The front and rear and left and right combinations can accurately control the positions of placing rivets and pulling rivets.

[0031] A feeding vibrator 39 and an electronic control device 40 are respectively provided on both sides of the frame 1. The electronic control device 40 is connected to the frame 1 signal, and the output end of the feeding vibrator 39 is connected to the riveting mechanism 4 through a hose. The electronic control device 40 controls the automated actions within the entire frame 1. The feeding vibrator 39 places the rivets one by one into the riveting mechanism 4 through the hose and prepares to place them into the battery shell.

[0032] The riveting mechanism 4 includes a riveting transverse sliding plate 7, a riveting cylinder 8 and a rivet tool head 9. A riveting vertical moving module 10 is installed on the riveting transverse sliding plate 7. The driving end of the riveting vertical moving module 10 is connected to a riveting vertical moving plate 11. A riveting slide cylinder 12 is fixed on the riveting vertical moving plate 11. The riveting cylinder 8 and the rivet tool head 9 are both fixed on the driving end of the riveting slide cylinder 12.

A rivet head spring is connected between the rivet clamp 15 and the rivet tool head 9. A rivet lens 16 and a rivet light source 17 are installed on the riveting vertical moving plate 11.

[0033] The feeding vibrator 39 inputs the rivet into the rivet tool head 9, the rivet light source 17 is responsible for providing light, and the rivet lens 16 photographs the hole position of the battery shell. Under the action of the riveting transverse moving plate 7 and the riveting vertical moving plate 11, the rivet tool head 9 moves horizontally and vertically to align with the hole position on the battery shell. Due to the presence of the rivet head spring, the rivet clamp 15 is closed and the rivet cannot fall into the battery shell. When the rivet cylinder 8 controls the rivet push rod 13 to push downward, the rivet clamp 15 is forced to open, and the rivet passes through the rivet tool head 9 and enters the battery shell.

[0034] The rivet mechanism 5 includes a rivet transverse moving frame 18, a rivet moving motor 19, a rivet rotating motor 20 and a rivet screw 21. The rivet transverse moving frame 18 is equipped with a rivet vertical moving module 22. The driving end of the rivet vertical moving module 22 is connected to a rivet vertical moving plate 23. The rivet moving motor 19 is fixed to the upper end of the rivet vertical moving plate 23. The rivet rotating motor 20 is fixed to the outer side of the rivet vertical moving plate 23. The driving end of the rivet moving motor 19 is connected to a rivet screw 24. The rivet screw rod 24 is threadedly connected to a rivet nut seat, and the rivet nut seat is fixed to the upper end of the rivet screw rod 21. The rivet screw rod 21 and the driving end of the rivet rotating motor 20 are both equipped with rivet synchronous wheels 25. A rivet synchronous belt 26 is connected between the rivet synchronous wheels 25. A sleeve 27 is fixed to the lower end of the rivet vertical moving plate 23. The lower end of the rivet screw rod 21 passes through the sleeve 27. A rivet lens 28 and a rivet light source 29 are installed on the rivet vertical moving plate 23.

[0035] The rivet light source 29 illuminates the battery shell, the rivet lens 28 grasps the position of the rivet, and the rivet moving motor 19 controls the up and down movement of the rivet screw 21. After the rivet is docked, the rivet rotating motor 20 controls the rivet screw 21 to rotate and rotate and fix it together with the inner thread of the rivet. Then the rivet moving motor 19 controls the rivet screw 21 to lift it vertically upward, and the rivet is pulled, expanded and fixed to the inside of the battery shell. Then the rivet rotating motor 20 controls the rivet screw 21 to rotate out the rivet. At this time, the rivet can be fixed to the battery shell to complete the riveting operation.

[0036] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be covered within the scope of protection of the present invention.
