[0038] like Figure 1 As shown, a plug assembly machine includes a frame, on which a plug conveying mechanism 200 and a plug assembly tower 300 are installed. The plug conveying mechanism 200 is located outside the plug assembly tower 300, and the plug conveying mechanism 200 conveys the plug to the plug assembly tower 300, and the plug assembly tower 300 assembles the plug on the battery. The plug conveying mechanism 200 and the plug assembly tower 300 are prior arts, and their structures and working principles are not described in detail. A battery polishing mechanism 400 and a plug pressing mechanism are also installed on the frame. Mechanism 500, the battery polishing mechanism 400 is located between the plug pressing mechanism 500, and the plug assembly tower 300 transports the battery after the plug is assembled to the battery polishing mechanism 400, the battery polishing mechanism 400 transports the polished battery to the plug pressing mechanism 500, the battery polishing mechanism 400 polishes the bottom of the battery, and then grinds off the residue at the bottom of the battery, and then the plug and the battery shell are compressed for the second time by the plug pressing mechanism 500, thereby ensuring the assembly quality of the plug.

[0039] In this embodiment, if Figure 7 , Figure 8 and Fig. 9As shown, the battery grinding mechanism 400 includes a battery conveyor tray 109, and the battery conveyor tray 109 is driven by a driving motor. A card slot for placing the battery is opened on the battery conveyor tray 109, and the driving motor is installed on the frame. When the battery plug is assembled, the battery is conveyed to the battery conveyor tray 109 through the conveyor tray, and then the battery conveyor tray 109 conveys the battery to the secondary pressing mechanism of the battery. In this embodiment, a support plate 102 is also installed on the frame, and a fixing plate 105 is horizontally installed on the support plate 102. A rotating motor 104 is installed on the fixing plate 105, and a power output shaft of the rotating motor 104 is installed There is a grinding wheel 107 for grinding the bottom of the battery shell, and the grinding wheel 107 is located below the fixed plate 105. The rotating shaft 508 of the battery conveying plate 109 is also equipped with an abutment plate 31, and the abutment plate 31 is located outside the battery conveying plate 109. A battery guide sleeve 108 is also installed on the frame, and the battery guide sleeve 108 is located above the battery conveying plate 109. An arc-shaped cavity for accommodating the battery is formed between the battery guide sleeve 108 and the battery conveying plate 109. When the battery is conveyed in the battery conveying plate 109, due to the existence of the arc-shaped cavity, the reliability of the battery conveying is guaranteed. In this embodiment, the rotating motor 104 belongs to The battery is usually a workpiece, so that the grinding wheel 107 is always in a rotating state. When the battery is conveyed upward through the battery conveying plate 109, the bottom of the battery gradually approaches the outer edge of the grinding wheel 107. When the bottom of the battery contacts the outer edge of the grinding wheel 107, the outer edge of the grinding wheel 107 applies a thrust to the battery, so that the head of the battery abuts against the abutment plate, so that the battery cannot move axially. Moreover, due to the existence of the battery guide sheath 108, the battery cannot be tilted. Therefore, as the battery gradually moves to the top of the battery conveying plate 109, the battery gradually approaches the outer edge of the grinding wheel 107. The bottom of the rear battery contacts the outer edge of the grinding wheel 107. Since the grinding wheel 107 is always in a rotating state, the grinding wheel 107 can grind off the residue on the bottom of the battery. In this embodiment, since the grinding wheel 107 rotates on the horizontal plane and the battery conveyor disc 109 rotates on the vertical plane, and the grinding wheel 107 is a circular part and the battery conveyor disc 109 is also a circular part, the angle between the grinding wheel 107 and the battery conveyor disc 109 on the projection surface of the horizontal plane provides space for the battery to be conveyed upward, and the grinding wheel 107 is always in a rotating state, and the battery can still be conveyed through the battery conveyor disc 109.

[0040] In this embodiment, the position of the grinding wheel 107 is adjusted by a technician according to design requirements. When the position of the grinding wheel 107 is adjusted, the grinding wheel 107 can just grind the bottom of the battery. However, in actual use, the grinding wheel 107 will be worn after long-term use. At this time, the position of the grinding wheel 107 needs to be adjusted. In this embodiment, Figure 7 , Figure 8 and Fig. 9 As shown, a strip groove is provided on the fixing plate 105, and the rotating motor 104 and the fixing plate 105 are locked by a bolt assembly installed in the strip groove. When adjusting, the bolt assembly is loosened, and then the position of the rotating motor 104 on the fixing plate 105 is adjusted, and then the distance between the grinding wheel 107 and the battery conveying plate 109 can be adjusted. When the position of the grinding wheel 107 is adjusted, the bolt assembly is locked.

[0041] In this embodiment, if Figure 7 , Figure 8 and Fig. 9 As shown, a linear motion pair 113 is provided on the support plate 102, and a lifting plate 103 is installed on the linear motion pair 113. The fixed plate 105 is horizontally installed on the lifting plate 103. By controlling the height of the lifting plate 103, the horizontal height of the fixed plate 105 can be controlled, so that the horizontal height of the grinding wheel 107 can be adjusted. Further, the linear motion pair 113 includes a slide rail, a slider and a driving device for driving the slider to slide on the slide rail. The slider is installed on the lifting plate 103, the slide rail is installed on the support plate 102, and the slider is slidably installed on the slide rail. In this embodiment, the driving device includes a servo motor 101 and an eccentric wheel 111. The servo motor 101 is installed on the support plate 102, and the eccentric wheel 111 is installed on the power output shaft of the servo motor 101. A support plate is provided on the side wall of the lifting plate 103, and a ball bearing 112 is installed on the support plate through the rotating shaft 508, and The ball bearing 112 is rolled and placed on the eccentric wheel 111. In this embodiment, the size of the battery is usually a standard part, so the height adjustment of the grinding wheel 107 is usually within a range, so there is no need to significantly adjust the height of the grinding wheel 107. In this embodiment, the servo motor 101 rotates, thereby driving the eccentric wheel 111 to rotate, and the eccentric wheel 111 rotates, so that the distance between the ball bearing 112 and the power output shaft changes, so that the vertical height of the lifting plate 103 can be adjusted. In this embodiment, the ball bearing 112 is located directly above the power output shaft of the servo motor 101. When the farthest end of the eccentric wheel 111 rotates to the top, the lifting plate 103 is in the upper stroke, and when the farthest end of the eccentric wheel 111 rotates to the bottom, the lifting plate 103 is in the down stroke. After the vertical height of the lifting plate 103 is adjusted, the height adjustment of the wear wheel can be achieved.

[0042] In this embodiment, if Figure 7 , Figure 8 and Fig. 9As shown, a protective cover 106 is also installed on the frame to cover the grinding wheel 107, and the side wall of the protective cover 106 close to the battery guide sleeve 108 is open. By setting the protective cover 106, the chips after grinding can be located in the protective cover 106 to prevent the chips from splashing randomly.

[0043] In this embodiment, if Fig.10 , Fig.11 and Fig.12 As shown, the rubber plug pressing mechanism 500 includes a rotating shaft 508, one end of which is rotatably mounted on the frame, and the other end of which is rotatably mounted on the mounting frame 507. The rotating shaft 508 is driven by a driving device, and the driving device is mounted on the frame. A rotating disk 501 is mounted on the end of the rotating shaft 508 away from the mounting frame 507, and a cam seat 506 is mounted on the mounting frame 507. A cam track is provided on the cam seat 506. The rotating shaft 508 passes through the cam The wheel seat 506 is provided with a bow rod mounting seat 504 on the rotating shaft 508. The bow rod mounting seat 504 is located between the cam seat 506 and the rotating disk 501. A limiting disk 502 is also installed on the side wall of the rotating disk 501 away from the bow rod mounting seat 504. A plurality of pressing bow rods 503 are installed on the bow rod mounting seat 504, and one end of the pressing bow rod 503 is located on the cam track. The pressing bow rod 503 moves axially under the action of the cam track. In this embodiment, Fig.13 and Fig.14As shown, the pressing bow rod 503 includes a rod body 511, one end of the rod body 511 is installed with a rolling bearing 112, the rolling bearing 112 is installed in the cam track, the other end of the rod body 511 passes through the bow rod mounting seat 504, and the other end of the rod body 511 is installed with a pressing head 517, further, a guide groove 512 is opened on the rod body 511, and a guide protrusion 505 that cooperates with the guide groove 512 is provided on the bow rod mounting seat 504, and the guide protrusion 505 is slidably fitted in the guide groove 512, through The cooperation of the guide protrusion 505 and the guide groove 512 prevents the compression bow rod 503 from rotating circumferentially relative to the bow rod mounting seat 504. In this embodiment, the other end of the rod body 511 has a guide rod 518, and a spring 514 is sleeved on the guide rod 518. A pressure head 517 is slidably sleeved on the guide rod 518. A buffer groove 515 is axially opened on the outer side wall of the pressure head 517. The buffer groove 515 is a waist-shaped hole. A limit pin 516 is radially installed on the guide rod 518. The end of the limit pin 516 cooperates with the installation The spring 514 is installed in the buffer groove 515 and is pressed between the pressure head 517 and the rod body 511. The spring 514 makes the pressure head 517 and the rubber plug in elastic contact, thereby preventing the rubber plug from being crushed. When the limit pin 516 abuts against the buffer groove 515, the pressing force on the rod body 511 can be transmitted to the pressure head 517, thereby ensuring the reliability of the rubber plug compression. When the compression is performed, the drive setting works, thereby driving the rotating disk 501, the limit disk 502, and the bow rod mounting seat 504 to rotate simultaneously. During the rotation of the bow rod mounting seat 504, the rolling bearing 513 rolls along the cam track, thereby causing the pressing bow rod 503 to move axially. During the plug pressing process, one end of the battery contacts the limit plate 502, so that the battery cannot move axially, thereby causing the plug to be pressed. Then, the pressing bow rod 503 is reset under the action of the cam track. At this time, the battery exits the plug pressing mechanism 500, and the battery enters the next process through the battery conveying device.

[0044] In this embodiment, if Figures 2 to 5As shown, the glue spreading mechanism 100 includes a battery feed tray 10, a battery rubbing mechanism 20, a battery glue coating transition tray 30, a battery discharge tray 40 and a glue liquid pool.
