The upper guide rod devices 4 and lower guide rod devices 5 are arranged in a one-to-one correspondence, meaning that the number of upper guide rod devices 4 and lower guide rod devices 5 is the same, and one upper guide rod device 4 and one lower guide rod device 5 work together. The assembly layer 6 is arranged upwards around the 3rd circumference, and the lower guide rod device 5 is located below the assembly layer 6. Specifically, the negative electrode bottom of the battery is assembled on the assembly layer 6 through the linkage of the upper guide rod device 4 and the lower guide rod device 5. The assembly layer 6 has a mold inlet 7, a negative electrode bottom inlet 8, a manganese sheet inlet 9, and an iron ring inlet 10 that are connected to it. The components for assembling the negative electrode bottom are transported into the assembly layer 6 through their corresponding inlets for assembly. The assembly materials enter the assembly layer 6 through the corresponding mold inlet 7, negative electrode bottom inlet 8, manganese sheet inlet 9, and iron ring inlet 10, and are then assembled as the assembly layer 6 rotates, and are assembled through the linkage of the upper guide rod device 4 and the lower guide rod device 5 during the rotation.

The upper cam bushing 22 is fitted onto the upper end of the rotating shaft mechanism 1, allowing the rotating shaft mechanism 1 to rotate within the upper cam bushing 22. The upper cam 21 is fitted onto and fixedly connected to the upper cam bushing 22, meaning the upper cam 21 is stationary. The upper working turntable 23 is fitted onto and fixedly connected to the rotating shaft mechanism 1, meaning the rotating shaft mechanism 1 drives the upper working turntable 23 to rotate together. The upper working turntable 23 is located below the upper cam 21. Several upper guide rod devices 4 are all located around the upper working turntable 23 and are clearance-fitted to it, meaning that several upper guide rod devices 4 can move back and forth inward around the upper working turntable 23. The upper cam 21 has an upward convex shape around its circumference. The wheel guide mechanism 24 and the upper cam guide mechanism 24 are designed to guide the upper guide rod device 4 to move up and down according to the work requirements. The upper ends of several upper guide rod devices 4 are all located inside the upper cam guide mechanism 24. The working method of the upper working plate mechanism 2 is that when the upper working turntable 23 rotates, each upper guide rod device 4 rotates with the upper working turntable 23. Then, each upper guide rod device 4 is guided by the upper cam guide mechanism 24 so that the upper guide rod device 4 can move up and down around the upper working turntable 23 to complete the work. In order to improve the service life of the assembly machine and prevent more dust from falling into the assembly machine, a cover plate 11 is provided above the upper working plate mechanism 2. The cover plate 11 is sleeved on the upper end of the upper cam bushing 22 and fixedly connected to it.

[0024] As shown in Figure 3, the upper guide rod device 4 includes an inner core rod device 41 and an outer guide rod device 42. The inner core rod device 41 is the device that works on the manganese sheet, and the outer guide rod device 42 is the device that works on the iron ring. The outer guide rod device 42 is located circumferentially on the upper working turntable 23 and is in clearance fit with it. It can be understood that the outer guide rod device 42 moves back and forth circumferentially on the upper working turntable. The inner core rod device 41 is located inside the outer guide rod device 42 and is in clearance fit with it. It can be understood that the inner core rod device 41 can move back and forth on the outer guide rod device 42. The upper cam... The guiding mechanism 24 includes an inner core guide groove 25 and a guide rod guide groove 26. The inner core guide groove 25 is located above the guide rod guide groove 26.

The upper end of the outer guide rod device 42 is provided with a guide rod connecting protrusion 44, one side of which is located within the guide rod guide groove 26. The function of the inner core guide groove 25 is to guide the upward movement of the inner core rod device 41 to achieve the operation of the inner core rod device 41. The function of the guide rod guide groove 26 is... The outer guide rod device 42 is moved up and down to achieve its operation. To improve the operational stability of the inner core rod device 41 and the outer guide rod device 42, a fixed plate 231 is provided around the upper working plate 23. The fixed plate 231 is provided with an inner core rod guide channel 232 and a guide rod guide channel 233. The inner core rod guide channel 232 is located above the guide rod guide channel 233. The inner core rod guide channel 232 has the same guide path as the inner core guide groove 25. It can be understood that the inner core rod guide channel 232 and the inner core guide groove 25 are connected by a guide rod guide channel 232 and a guide rod guide channel 233. The path of the groove 25 is set accordingly, so that the inner core rod device 41 moves up and down along the inner core guide groove 25 during rotation. The guide rod guide channel 233 has the same guide path as the guide rod guide groove 26. It can be understood that the guide rod guide channel 233 and the guide rod guide groove 26 are set accordingly, so that the outer guide rod device 42 moves up and down along the guide rod guide groove 26 during rotation. The other side of the inner core connecting protrusion 43 is located in the inner core rod guide channel 232, and the other side of the guide rod connecting protrusion 44 is located in the guide rod guide channel 233.

[0025] The inner core rod device 41 has an upper vacuum channel 45 at its lower end, and the outer guide rod device 42 has an upper vacuum port 46 on its side wall. The upper end of the upper vacuum channel 45 is connected to the upper vacuum port 46 through the gap between the inner core rod device 41 and the outer guide rod device 42. That is, the external vacuum equipment controls the operation of the inner core rod device 41 by drawing a vacuum through the vacuum port 46. The inner core rod device 41 adsorbs the manganese sheet through the upper vacuum channel 45. The outer guide rod device 42 acts as a pressing force on the iron ring component.

[0026] The lower working disc mechanism 3 includes a lower cam 31, a lower cam bushing 32, and a lower working turntable 33. The lower cam bushing 32 is located at the lower end of the rotating shaft mechanism 1, which can rotate within the lower cam bushing 32. The lower cam 31 is sleeved on and fixedly connected to the lower cam bushing 32, meaning the lower cam 31 is stationary. The lower working turntable 33 is located on and fixedly connected to the rotating shaft mechanism 1, meaning the lower working turntable 33 rotates together with the rotating shaft mechanism 1. The lower working turntable 33 is located above the lower cam 31. Several lower guide rod devices 5 are located around the lower working turntable 33 and are clearance-fitted to it; these can be understood as lower guide rods. The device 5 can move up and down around the lower working turntable 33. The lower cam 31 is provided with a lower cam guide mechanism 34. The lower ends of several lower guide rod devices 5 are provided with lower connecting protrusions 53. The lower connecting protrusions 53 are all located in the lower cam guide mechanism 34. The function of the lower cam guide mechanism 34 is to guide the lower guide rod devices 5 to move up and down according to the guide path set according to the work needs. The lower working turntable 33 is provided with an assembly layer 6. The negative electrode bottom is assembled in the assembly layer 6. The assembly layer 6 is provided with a protective fence 61 around its perimeter. The function of the protective fence 61 is to prevent the parts on the assembly layer 6 from falling off.

[0027] As shown in Figure 4, the lower guide rod device 5 has a lower vacuum channel 51 at its upper end and a lower vacuum port 52 on its side wall. The lower vacuum channel 51 and the lower vacuum port 52 are connected. The lower guide rod device 5 performs adsorption on the negative electrode bottom through the lower vacuum channel 51.

[0028] As shown in Figure 5, the assembly layer 6 includes a manganese sheet working layer 62, an iron ring working layer 63, and a negative electrode bottom working layer 64. The manganese sheet working layer 62, iron ring working layer 63, and negative electrode bottom working layer 64 are arranged from top to bottom. The manganese sheet working layer 62 has a manganese sheet station 621 on its circumference, the iron ring working layer 63 has an iron ring station 631 on its circumference, and the negative electrode bottom working layer 64 has a negative electrode bottom station 641 on its circumference. The negative electrode bottom and the mold sleeve both enter the lower working turntable 33 within the negative electrode bottom layer. The upper guide rod device 4, manganese sheet station 621, and iron ring station 631 are also included. The negative electrode bottom station 641 and the lower guide rod device 5 are set up one-to-one. This can be understood as an upper guide rod device 4, a manganese sheet station 621, an iron ring station 631, a negative electrode bottom station 641, and a lower guide rod device 5 all being located in the same vertical space. That is, when an upper guide rod device 4 moves downwards, it can pass through a manganese sheet station 621, an iron ring station 631, a negative electrode bottom station 641, and dock with the lower guide rod device 5 to complete the work. The mold sleeve inlet 7 and the negative electrode bottom inlet 8 respectively dock with the negative electrode bottom working layer 64, i.e., the mold... Both the sleeve and the negative electrode bottom enter the negative electrode bottom station 641 from the circumference of the negative electrode bottom working layer 64. The manganese sheet inlet 9 connects with the manganese sheet working layer 62, meaning the manganese sheet enters the manganese sheet station 621 from the circumference of the manganese sheet working layer 62. The iron ring inlet 10 connects with the iron ring working layer 63, meaning the iron ring enters the iron ring station 631 from the circumference of the iron ring working layer 63. In the rotation direction of the assembly layer 6, the sleeve inlet 7 is set before the negative electrode bottom inlet 8, the negative electrode bottom inlet 8 is set before the manganese sheet inlet 9, and the manganese sheet inlet 9 is set before the iron ring inlet 10. That is, the sleeve inlet 7... The negative electrode bottom inlet 8, manganese sheet inlet 9, and iron ring inlet 10 are connected to the assembly layer 6 in sequence. This arrangement is to enable each assembly component to be combined at the next inlet after entering its respective working area, thereby improving work efficiency. A support plate 632 is provided below the iron ring working layer 63. The front end of the support plate 632 is located at the iron ring inlet 10, and the rear end of the support plate 632 is located behind the iron ring inlet 10 in the direction of rotation. The function of the support plate 632 is to support the entering iron ring and prevent the iron ring from falling off before assembly.

[0029] According to the configuration position requirements of the external equipment, the rotating shaft mechanism 1 rotates counterclockwise. In the plane of the assembly layer 6, in the counterclockwise rotation direction of the assembly layer 6, the included angle between the negative electrode bottom inlet 8 and the mold sleeve inlet 7 is 45° to 49°, the included angle between the manganese sheet inlet 9 and the negative electrode bottom inlet 8 is 148° to 152°, and the included angle between the iron ring inlet 10 and the manganese sheet inlet 9 is 43° to 47°.

[0030] As shown in Figure 6, the working method and principle of the negative electrode bottom assembly machine are as follows: The rotating shaft mechanism 1 rotates counterclockwise. First, at the mold sleeve inlet 7 of the negative electrode bottom working layer 64, the mold sleeve (the mold sleeve is ring-shaped) is scraped into the negative electrode bottom station 641 of the negative electrode bottom working layer 64. As the negative electrode bottom working layer 64 rotates, when the mold sleeve rotates to the negative electrode bottom inlet 8, the negative electrode bottom is scraped into the negative electrode bottom station 641 using the negative electrode bottom station 641. At this time, the lower guide rod device 5 passes through the middle of the mold sleeve. The lower vacuum channel 51 at the front end holds the negative electrode bottom, and then the lower guide rod device 5 is moved downward by the lower cam guide mechanism 34 to put the negative electrode bottom into the mold sleeve. Continue to rotate counterclockwise. When it rotates to the manganese sheet inlet 9, the manganese sheet station 621 scrapes the manganese sheet into the manganese sheet station 621 of the manganese sheet working layer 62. At this time, the inner core rod device 41 moves downward through the upper vacuum channel 45 to hold the manganese sheet and continues to rotate to maintain a distance. When it rotates to the iron ring inlet 10, the iron ring is scraped into the iron ring by the iron ring station 631. Working layer 63, because a support plate 632 is provided below the iron ring working layer 63, the iron ring will be supported by the support plate 632 and will not fall. In the area where the support plate 632 is located, the inner core rod device 41 guides the manganese sheet into the iron ring by descending through the inner core guide groove 25. When it continues to rotate to the end of the support plate 632, the lower guide rod device 5 supports the bottom of the negative electrode and rises. The outer guide rod device 42 presses the iron ring containing the manganese sheet into the bottom of the negative electrode through the guide rod guide groove 26 to complete the assembly. Finally, the lower guide rod... The assembled negative electrode base is vacuum-held and sucked downwards into the mold sleeve, then connected to the next process. When the negative electrode base assembly machine starts, the negative electrode base at negative electrode base inlet 8, the manganese sheet at manganese sheet inlet 9, and the iron ring at iron ring inlet 10 will simultaneously enter their respective working stations. Because the working stations rotate synchronously, a certain number of negative electrode bases, manganese sheets, and iron rings cannot be assembled when the machine starts. These negative electrode bases, manganese sheets, and iron rings on their respective working stations will be rejected after their inlets.
