[0002] In the battery manufacturing field, especially in the production of power / energy storage battery, the accurate positioning and stable installation of the sealing ring are crucial to ensure the air tightness and assembly quality of the battery.

DETAILED DESCRIPTION

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0035] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0036] To address the problems of inconvenient gripping and poor installation stability of existing sealing rings, this application provides a battery manufacturing apparatus. The battery manufacturing apparatus includes at least a sealing ring positioning device, a sealing ring 1300, a battery cell 1400, and an adapter plate. The adapter plate is disposed on the top of the battery cell 1400 and has an adapter plate terminal 1200. The sealing ring positioning device has a suction nozzle 370. After the sealing ring 1300 is picked up through the suction nozzle 370, the sealing ring 1300 is positioned and fitted onto the adapter plate terminal 1200, thus completing the installation and fixation of the sealing ring 1300.

[0037] The battery manufacturing equipment in this embodiment can accurately install and position the sealing ring 1300 onto the adapter terminal 1200 through the suction nozzle 370 on the sealing ring positioning device, which helps to ensure the installation accuracy of the sealing ring 1300 and improves the efficiency of battery production and assembly.

[0038] like Figures 1 to 12 As shown, the sealing ring positioning device includes a bracket 10, a vibratory plate 20, and a material picking component 30. The vibratory plate 20 is mounted on the bracket 10 and has a mounting groove 210 with a top opening. The mounting groove 210 is used to accommodate the sealing ring 1300. The material picking component 30 is used to adsorb the sealing ring 1300 and pick up the sealing ring 1300 inside the mounting groove 210.

[0039] The bracket 10 is used to provide installation for the vibratory feeder 20 and the material handling assembly 30. The bracket 10 has a base plate 110, and the vibratory feeder 20 and the material handling assembly 30 are fixedly installed on the top surface of the base plate 110.

[0040] The vibratory feeder 20 of this application includes a vibration source and a disc body disposed on the vibration source. The disc body has a mounting groove 210 with a top opening. During use, a sealing ring 1300 is disposed inside the mounting groove 210. By starting the vibration source, the vibration source drives the disc body to vibrate, thereby adjusting the orientation of the sealing ring 1300 inside the mounting groove 210, which facilitates the material picking component 30 to adsorb the sealing ring 1300. The vibration source can be a vibration motor, the disc body has a cubic structure, and the opening of the mounting groove 210 is rectangular.

[0041] Specifically, the material handling assembly 30 includes a support column 310, a driving mechanism, and an adsorption mechanism. The support column 310 is mounted on the support bracket 10, and the driving mechanism is mounted on the support column 310. The driving mechanism is driven to move the adsorption mechanism toward or away from the mounting groove 210. The adsorption mechanism has a suction nozzle 370. The end of the suction nozzle 370 facing the mounting groove 210 has an annular protrusion 372. After the sealing ring 1300 is adsorbed, at least a portion of it is accommodated in the inner cavity of the annular protrusion 372. The annular protrusion 372 has a plurality of notches 373 spaced apart along the circumference. The notches 373 communicate with the inner cavity. After the sealing ring 1300 in the inner cavity is deformed, a portion of it is squeezed into the notches 373.

[0042] like Figure 6 As shown, the suction nozzle 370 of the sealing ring positioning device of this application has an annular protrusion 372. When adsorbing the sealing ring 1300, the sealing ring 1300 can be installed and fixed by positioning at least a part of the sealing ring 1300 in the inner cavity of the annular protrusion 372. The annular protrusion 372 has the effect of limiting the sealing ring 1300, ensuring the stable connection between the sealing ring 1300 and the suction nozzle 370, which is beneficial to improving the adsorption stability of the sealing ring 1300.

[0043] like Figure 6 As shown, this application provides multiple notches 373 on the annular protrusion 372. When the sealing ring positioning device positions and fits the sealing ring 1300 onto the adapter plate post 1200, the sealing ring 1300 is compressed by the adapter plate post 1200, causing it to deform and partially extend into the notches 373. The notches 373 provide clearance for the deformation of the sealing ring 1300, thus avoiding interference between the sealing ring 1300 and the adapter plate post 1200, which would lead to low installation efficiency. The notches 373 facilitate the installation of the sealing ring 1300. After the sealing ring 1300 is installed, the notches 373 facilitate the disengagement of the nozzle 370 from the sealing ring 1300, thereby improving the positioning accuracy of the sealing ring 1300 and increasing the battery assembly efficiency.

[0044] In this embodiment, the suction nozzle 370 has a pressure chamber and an adsorption port 374. The pressure chamber is used to provide positive and negative pressure, and the adsorption port 374 is used to adsorb the sealing ring 1300. The structure of the suction nozzle 370 in this application is not completely the same when it is applied to adsorb sealing rings 1300 with different structures.

[0045] In one specific implementation of this embodiment, such as Figure 12 As shown, the sealing ring 1300 has an O-shaped structure, the suction nozzle 370 includes a housing 371, a pressure chamber is formed inside the housing 371, and an annular protrusion 372 is provided on the side of the housing 371 facing the mounting groove 210.

[0046] The housing 371 has an adsorption port 374 communicating with the pressure chamber on the side facing the mounting groove 210. The adsorption port 374 is located in the inner area of ​​the annular protrusion 372. By setting the adsorption port 374 on the housing 371 in the inner area of ​​the annular protrusion 372, the suction force of the adsorption port 374 can position and install the sealing ring 1300 in the inner cavity of the annular protrusion 372 when the nozzle 370 adsorbs the sealing ring 1300. When the sealing ring 1300 is positioned and fitted onto the adapter plate pole 1200, the sealing ring 1300 can partially extend into the notch 373 after being squeezed and deformed, thereby improving the installation accuracy and efficiency of the sealing ring 1300.

[0047] The housing 371 has a columnar structure to facilitate the placement of the annular protrusion 372 on the end face of the housing 371, and to facilitate the placement of the adsorption port 374 on the end face of the housing 371.

[0048] In this embodiment, multiple adsorption ports 374 are provided, and the multiple adsorption ports 374 are equally spaced along the circumference of the annular protrusion 372. The arrangement of multiple adsorption ports 374 is beneficial to improving the uniformity of the suction force on the sealing ring 1300, and thus improving the stability of the adsorption and positioning of the sealing ring 1300 in the inner cavity of the annular protrusion 372. Similarly, when it is necessary to fit the sealing ring 1300 onto the adapter plate pole 1200, the gas discharged from the adsorption port 374 can make the sealing ring 1300 receive a uniform thrust, so that the sealing ring 1300 is stably positioned on the adapter plate pole 1200.

[0049] In one specific implementation of this embodiment, such as Figures 9 to 11 As shown, the sealing ring 1300 has a stepped structure, the suction nozzle 370 includes a housing 371, a pressure chamber is formed inside the housing 371, and an annular protrusion 372 is provided on the side of the housing 371 facing the mounting groove 210.

[0050] The annular protrusion 372 has an axially extending adsorption channel that communicates with the pressure chamber, and the adsorption port 374 of the adsorption channel is located on the end face of the annular protrusion 372 away from the housing 371.

[0051] Specifically, the sealing ring 1300 has an inner edge 1320 disposed in the inner cavity of the annular protrusion 372 and an outer peripheral edge 1310 abutting against the end face of the annular protrusion 372. When the suction nozzle 370 adsorbs the sealing ring 1300, the suction port 374 adsorbs the outer peripheral edge 1310 of the sealing ring 1300 to position and adsorb the sealing ring 1300. When the sealing ring 1300 is positioned and fitted onto the adapter plate pole 1200, the inner edge 1320 of the sealing ring 1300 is deformed by compression and can partially extend into the notch 373 to improve the installation accuracy and installation efficiency of the sealing ring 1300.

[0052] The housing 371 has a columnar structure to facilitate the placement of the annular protrusion 372 on the end face of the housing 371.

[0053] In this embodiment, multiple adsorption ports 374 are provided, and the multiple adsorption ports 374 are equally spaced along the circumference of the annular protrusion 372. The arrangement of multiple adsorption ports 374 is beneficial to improving the uniformity of the suction force on the outer periphery 1310 of the sealing ring 1300, and thus improving the stability of the adsorption and positioning of the sealing ring 1300 on the annular protrusion 372. Similarly, when the sealing ring 1300 needs to be fitted onto the adapter plate pole 1200, the gas discharged from the adsorption port 374 can make the sealing ring 1300 receive a uniform thrust, so that the sealing ring 1300 is stably positioned on the adapter plate pole 1200.

[0054] In this embodiment, the adsorption mechanism also includes a cylinder, which is mounted on the bracket 10. The cylinder is connected to the pressure chamber via an air pipe. When the sealing ring 1300 needs to be adsorbed, the cylinder provides negative pressure to generate suction at the adsorption port 374. When the sealing ring 1300 needs to be mounted and positioned on the adapter plate pole 1200, the cylinder provides positive pressure to generate thrust at the adsorption port 374.

[0055] like Figure 3 and Figure 5 As shown, the driving mechanism is used to adjust the position of the adsorption mechanism, that is, to adjust the position of the suction nozzle 370. The driving mechanism includes a rotary drive 320, a connecting frame 330, a first drive 340, and a mounting frame 350.

[0056] Among them, the rotary drive component 320 is a rotary motor or rotary cylinder or other structural component used to provide rotational force, and the first drive component 340 is a telescopic motor or telescopic cylinder or other structural component used to provide telescopic force.

[0057] Specifically, the rotary drive 320 is disposed on the support column 310 and is drivenly connected to one end of the connecting frame 330. The first drive 340 is disposed at the other end of the connecting frame 330. The first drive 340 has an output shaft that is telescopically disposed along the height direction of the support column 310. The mounting frame 350 is disposed on the output shaft and the suction nozzle 370 is disposed on the mounting frame 350.

[0058] The rotary drive 320 drives the connecting frame 330 to rotate, thereby adjusting the positions of the first drive 340, the mounting frame 350 and the suction nozzle 370 set on the connecting frame 330. After the suction nozzle 370 adsorbs the sealing ring 1300, the rotary drive 320 drives the suction nozzle 370 to rotate above the adapter plate pole post 1200 to transfer the sealing ring 1300.

[0059] In this embodiment, the first driving member 340 is used to adjust the height of the mounting bracket 350 and the suction nozzle 370 so that when it is necessary to adsorb the sealing ring 1300 or to fit the sealing ring 1300 onto the adapter plate pole 1200, the first driving member 340 drives the suction nozzle 370 to move downward.

[0060] like Figure 3 and Figure 5 As shown, in order to improve the installation efficiency of the sealing ring 1300, the suction nozzles 370 of this application are arranged in pairs. The two suction nozzles 370 arranged in pairs correspond to two adapter plate posts 1200, namely the positive adapter plate post and the negative adapter plate post, which is conducive to improving the assembly efficiency of the sealing ring 1300.

[0061] It should be noted that different models of battery cells 1400 are compatible with positive and negative electrode terminals with different spacing. To improve the application scenarios of this application, the driving mechanism of this application also includes a second driving component 360. The second driving component 360 is disposed on the mounting bracket 350, and two suction nozzles 370 arranged in pairs are respectively disposed on the two second driving components 360.

[0062] In this embodiment, the second driving component 360 is a structural component such as a motor or a cylinder. The second driving component 360 can drive the suction nozzle 370 to move in position so that the two suction nozzles 370 move toward each other or toward each other, thereby making the two suction nozzles 370 suitable for matching positive and negative electrode terminals with different spacing.

[0063] like Figure 1 and Figure 2As shown, the bracket 10 has a mounting plate 130 disposed on one side of the top of the mounting groove 210 and a support column 120 supported between the base plate 110 of the mounting plate 130. The sealing ring positioning device also includes a light source 40, a first positioning detection element 50 and a controller. The controller is signal connected to the drive mechanism, the adsorption mechanism, the vibrating plate 20, the light source 40 and the first positioning detection element 50.

[0064] The first positioning detection component 50 is a positioning camera used to detect the sealing ring 1300. It is used to provide feedback on the coordinates of the sealing ring 1300 with the correct orientation inside the mounting groove 210, and transmits the feedback information to the controller. The controller controls the drive mechanism and the adsorption mechanism to move the suction nozzle 370 toward the sealing ring 1300 at the coordinate position and adsorb the sealing ring 1300, which helps to improve the adsorption efficiency of the sealing ring 1300.

[0065] The light source 40 is set on the mounting plate 130 and is used to provide illumination. Specifically, it can be an LED light source. The light from the light source 40 covers the opening of the mounting groove 210 to facilitate the first positioning detection element 50 to fully detect the sealing ring 1300 inside the mounting groove 210.

[0066] Specifically, the first positioning detection element 50 is disposed on the mounting plate 130, and the projection of the first positioning detection element 50 on the bottom surface of the mounting groove 210 is located in the central area of ​​the bottom surface of the groove, so as to be able to perform the seal detection directly facing the mounting groove 210.

[0067] In this embodiment, the light source 40 may be disposed on the outer periphery of the first positioning detection element 50 to avoid the phenomenon of the first positioning detection element 50 affecting the light and the light source 40 interfering with the imaging of the positioning camera.

[0068] like Figure 1 , Figure 2 and Figure 7 As shown, to ensure accurate positioning of the sealing ring 1300 and the adapter post 1200, the sealing ring positioning device also includes a positioning frame 60, a second positioning detection element 70, a third driving element 80, and a third positioning detection element 90. The second positioning detection element 70 and the third driving element 80 are disposed on the positioning frame 60. The second positioning detection element 70 is used to detect the position of the positive adapter post and the negative adapter post to determine the setting position and corresponding spacing of the positive adapter post and the negative adapter post, and to feed the detection information back to the controller.

[0069] Specifically, the positioning frame 60 is disposed on one side of the vibratory feeder 20, and the third positioning detection element 90 is disposed at the telescopic end of the third driving element 80. The third driving element 80 drives the third positioning detection element 90 to move toward or away from the mounting groove 210. The third driving element 80 is a telescopic cylinder or a telescopic motor to drive the third positioning detection element 90 to telescopically move.

[0070] In this embodiment, the second positioning detection element 70 is a positioning camera. The positioning camera is used to image the positive and negative adapter poles and feed back the coordinate and spacing information to the controller. The controller controls the rotation drive 320 to rotate and adjust the suction nozzle 370 to the coordinates of the corresponding adapter pole 1200. At the same time, the controller controls the second drive 360 ​​to adjust the distance between the two suction nozzles 370, thereby adapting to the corresponding positive and negative adapter poles.

[0071] In this embodiment, the third positioning detection element 90 is a 3D profiler. After the sealing ring 1300 is installed to the adapter plate pole post 1200, the third positioning detection element 90 extends towards the mounting groove 210 under the drive of the third driving element 80, detects whether the installation position of the sealing ring 1300 is correct, and feeds back the detection information to the controller.

[0072] like Figure 4 As shown, the sealing ring positioning device includes a feeding assembly 1100, which is mounted on the bracket 10. The feeding assembly 1100 is used to feed the sealing ring 1300 into the mounting groove 210 of the vibratory plate 20.

[0073] Specifically, the feeding assembly 1100 includes a housing 1110, a conveyor belt 1120, and a fourth drive member 1130. The housing 1110 is mounted on the support 10 and has a mounting cavity and an inlet 1111 and an outlet 1112 communicating with the mounting cavity. The outlet 1112 is located at the end of the housing 1110 and above the opening of the mounting groove 210. The inlet 1111 is located at the top of the housing 1110 and on the side of the outlet 1112 away from the mounting groove 210. The conveyor belt 1120 is rotatably mounted inside the housing 1110. The fourth drive member 1130 is mounted on the support 10 and is drivenly connected to the conveyor belt 1120.

[0074] The fourth driving component 1130 is a motor. The two ends of the conveyor belt 1120 are sleeved on the transmission rollers. The transmission rollers are rotatably connected to the outer shell 1110. The fourth driving component 1130 is driven to one end of the transmission roller to drive the transmission roller to rotate, thereby driving the conveyor belt 1120 to rotate.

[0075] In this embodiment, the sealing ring 1300 enters the conveyor belt 1120 inside the housing 1110 through the feed inlet 1111 and moves with the conveyor belt 1120 toward the discharge outlet 1112, and moves from the discharge outlet 1112 to the inside of the mounting groove 210; in order to ensure that all the sealing rings 1300 entering the housing 1110 are on the conveyor belt 1120, the width of the conveyor belt 1120 is greater than the width of the feed inlet 1111.

[0076] In this embodiment, the height of the end of the outer shell 1110 with the discharge port 1112 is greater than the height of the other end of the outer shell 1110, that is, the distance between one end of the inlet 1111 and the bottom plate 110 is greater than the distance between the other end of the outer shell 1110 and the bottom plate 110, so as to facilitate the addition of the sealing ring 1300 at the inlet 1111, and at the same time, to facilitate the sealing ring 1300 at the discharge port 1112 to fall into the interior of the mounting groove 210; the outer shell 1110 is arranged in an inclined structure, and the conveyor belt 1120 is simultaneously inclined and arranged inside the outer shell 1110. The conveyor belt 1120 has a protrusion plate arranged in the width direction. The protrusion plate is arranged to support the sealing ring 1300, so as to push the sealing ring 1300 towards the discharge port 1112 and push it out from the discharge port 1112.

[0077] The implementation method of the sealing ring positioning device in this embodiment is as follows:

[0078] The sealing rings 1300 are batch-loaded into the feeding assembly 1100. The feeding assembly 1100 automatically feeds the sealing rings 1300 periodically according to the number of sealing rings 1300 in the vibratory feeder 20. After feeding is completed, the vibratory feeder 20 starts vibrating for 1-3 seconds, changing the orientation of the sealing rings 1300. The first positioning detection element 50 starts scanning after the vibration is completed, detects the sealing rings 1300 with the correct orientation, identifies the coordinates and uploads them to the controller, and sends a feedback signal to the adsorption mechanism. At the same time, the incoming sealing rings 1300 are placed into the set position on the adapter plate pole 1200. The second positioning... The position detection element 70 extends to detect the position of the adapter post 1200 and reads the coordinates of the adapter post 1200, which are then uploaded to the controller and fed back to the adsorption mechanism. After the adsorption mechanism reads the coordinates, it moves the suction nozzle 370 above the appropriate sealing ring 1300 and opens the negative pressure. The first driving element 340 drives the suction nozzle 370 to descend so that the suction nozzle 370 picks up the sealing ring 1300. Then, the first driving element 340 drives the suction nozzle 370 that has picked up the sealing ring 1300 to rise. The suction nozzle 370 on the other side repeats this action to complete the pick-up. The rotary drive 320 drives the suction nozzle 370 to rotate, and moves the suction nozzle 370 above a certain adapter plate post 1200 according to the signal. The first drive 340 drives the suction nozzle 370 to descend, so that the sealing ring 1300 picked up by the suction nozzle 370 is inserted into the adapter plate post 1200 and kept in a compressed state. The suction nozzle 370 closes the negative pressure and opens the positive pressure. The first drive 340 drives the suction nozzle 370 to rise and disengage from the sealing ring 1300. The positive pressure plays a holding role, keeping the sealing ring 1300 in contact with the adapter plate post 1200. The suction nozzle 370 on the other side repeats this action. The suction nozzle 370 rises and moves to the vibratory plate 20 for the next set of installation and material picking. The third drive 80 starts and extends above the adapter plate post 1200. The third positioning detection element 90 scans the overall position of the two sealing rings 1300.

[0079] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0080] The sealing ring positioning device of this application uses a suction nozzle 370 with an annular protrusion 372. When adsorbing the sealing ring 1300, at least a portion of the sealing ring 1300 can be positioned in the inner cavity of the annular protrusion 372 to achieve the installation and fixation of the sealing ring 1300, which is beneficial to improving the adsorption stability of the sealing ring 1300. Furthermore, by providing multiple notches 373 on the annular protrusion 372, when the sealing ring positioning device positions and fits the sealing ring 1300 onto the adapter plate pole 1200, the sealing ring 1300 is subjected to the adapter plate pole 1200. After compression by 200, the sealing ring 1300 deforms and partially extends into the notch 373. The notch 373 provides clearance for the deformation of the sealing ring 1300, thus avoiding interference between the sealing ring 1300 and the adapter post 1200, which would lead to low installation efficiency. The notch 373 facilitates the installation of the sealing ring 1300. After the sealing ring 1300 is installed, the notch 373 facilitates the separation of the nozzle 370 from the sealing ring 1300, thereby improving the positioning accuracy of the sealing ring 1300 and improving the battery assembly efficiency.
