Description

Technical Field

[0002] Most existing electronic devices use sealed batteries such as lithium-ion or nickel-metal hydride batteries. During the production of sealed batteries, after the electrolyte is injected, the electrolyte injection port needs to be sealed with a pin to prevent leakage. This pinning process is typically done manually, where the sealing pin is manually pressed into the electrolyte injection port.

[0078] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0079] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0080] Please see details. Figure 1-2 This application provides a battery sealing nail mounting device 1000, including a frame and a nail mounting mechanism 100, a first positioning mechanism 200, and a second positioning mechanism 300 disposed on the frame, wherein:

[0081] The nailing mechanism 100 includes multiple nailing stations, and each nailing station is provided with a nailing mechanism 400 for obtaining sealing nails and a nailing drive mechanism 500 for driving the nailing mechanism 400 to move along the first direction Z.

[0082] The first positioning mechanism 200 is disposed below the upper nailing mechanism 100, and the first positioning mechanism 200 is used to position the sealing nails at each of the upper nailing stations.

[0083] The second positioning mechanism 300 is disposed on one side of the nailing mechanism 100. The second positioning mechanism 300 is used to position the battery to be nailed, so that the nailing device 1000 performs the nailing operation based on the positioning of the sealing nail and the battery to be nailed.

[0084] The battery sealing nail mounting device 1000 provided in this application embodiment can mount multiple sealing nails simultaneously through the mounting mechanism 100. The first positioning mechanism 200 below the mounting mechanism 100 can simultaneously position the acquired multiple sealing nails during the nail removal process, thereby improving positioning efficiency. The second positioning mechanism 300 can simultaneously position the battery during the nail removal process. During the mounting process, the mounting is controlled by the positioning of the sealing nail and the positioning of the battery, thereby improving the mounting efficiency, positioning accuracy, and mounting accuracy of the battery sealing nails.

[0085] It is understood that in this embodiment, the method by which the nail-attaching mechanism 100 acquires the sealing nail is not limited to suction and gripping. In different embodiments, the appropriate method can be selected as needed. This embodiment uses suction as an example for illustrative description. For the positioning methods of the first positioning mechanism 200 and the second positioning mechanism 300, image processing technology can be used for positioning. For example, image segmentation, analysis, transformation, and extraction can be performed using computer vision, computer graphics, and digital image processing methods to complete the relevant functions. This embodiment uses a CCD camera as an example for illustrative description. In different embodiments, other image capturing devices (such as 3D cameras) or positioning devices with other positioning methods can also be selected; this application does not limit this.

[0086] In this application, the process of moving the mounting mechanism 100 to the dismounting mechanism 900 to obtain the sealing nail and then moving the obtained sealing nail to the mounting position is called the nail removal process. The process of placing the obtained sealing nail onto the battery using the mounting mechanism 100 is called the mounting process. In this application, the first direction is defined as the Z-axis direction, the second direction is defined as the Y-axis direction, and the third direction is defined as the X-axis direction. In different embodiments, the second direction Y and the third direction X can be interchanged.

[0087] like Figure 3As shown, the nailing device 1000 includes a first nailing moving mechanism 600, a second nailing moving mechanism 700, and a positioning driving mechanism 800. The first nailing moving mechanism 600 is used to drive the nailing mechanism 100 and the second positioning mechanism 300 to move along a second direction Y; the second nailing moving mechanism 700 is used to drive the nailing mechanism 100 and the second positioning mechanism 300 to move along a third direction X; and the positioning driving mechanism 800 is used to drive the first positioning mechanism 200 to move along a first direction Z.

[0088] In this embodiment, the upper nail drive mechanism 500, the first upper nail moving mechanism 600, the second upper nail moving mechanism 700, and the positioning drive mechanism 800 can be linear moving mechanisms such as cylinders, linear motors, gear rack mechanisms, and lead screw and nut mechanisms, which are selected as needed in different embodiments. In this embodiment, the first upper nail moving mechanism 600 and the second upper nail moving mechanism 700 are described as linear motors, and the positioning drive structure is a lead screw and nut mechanism, as an example.

[0089] The first nail-attaching moving mechanism 600 is used to drive the nail-attaching mechanism 100 to move back and forth during the nail-attaching process, and the second nail-attaching moving mechanism 700 is used to drive the nail-attaching mechanism 100 to move left and right during the nail-removing process. The second nail-attaching moving mechanism 700 is fixedly mounted on the first slide block 31 of the first nail-attaching moving mechanism 600, and the second nail-attaching moving mechanism 700 moves back and forth together with the first slide block 31; wherein, as shown in the figure Figure 4 As shown, the linear motor of the second nail-attaching mechanism 700 includes a linear guide rail and two second slides 32 mounted on the linear guide rail. The nail-attaching mechanism 100 and the second positioning mechanism 300 are respectively mounted on the two second slides 32, which simplifies the mechanism, saves costs, and conserves space. Simultaneously, it allows the movement of the second positioning mechanism 300 and the nail-attaching mechanism 100 to be separated and independent, enabling battery positioning during nail removal and improving work efficiency.

[0090] The second positioning mechanism 300 is mounted on the positioning drive mechanism 800, which in turn is mounted on the second slide 32 of the second nail-mounting mechanism 700. It can move left and right together with the second nail-mounting mechanism 700. It is understood that the positioning drive mechanism 800 can control the vertical height of the CCD camera and its field of view. In different embodiments, based on the number of batteries to be nailed on the fixture 140, all batteries are placed within the field of view of the CCD camera, thus omitting the need for the positioning drive mechanism 800. This can be selected as needed in different embodiments. Similarly, the first positioning mechanism 200 can be fixed or movable. In this application, it is described as follows: the first positioning mechanism 200 is fixedly mounted on the frame and located below the nail-mounting mechanism 100. By setting the movement range of the nail-mounting mechanism 100 within the field of view of the CCD camera of the first positioning mechanism 200, each acquired sealing nail can be positioned during the movement of the nail-mounting mechanism 100, improving positioning accuracy and simplifying the structure.

[0091] Specifically, such as Figure 5 As shown, the nailing device 1000 further includes a nailing mechanism 900 and a fixture 140 disposed on the frame. The nailing mechanism 900 is disposed on one side of the nailing device 1000 along the second direction Y. The fixture 140 is provided with a plurality of batteries to be nailed and is disposed on the other side of the nailing device 1000 along the second direction Y. The plurality of nailing stations are arranged in an array along the second direction Y. The first positioning mechanism 200 is disposed on the movement trajectory of the nailing station along the second direction Y. The second positioning mechanism 300 is disposed on the side of the nailing device 1000 along the second direction Y near the fixture 140.

[0092] The arrangement and movement of the stapler mechanism 900, stapler mechanism 100, fixture 140, first positioning mechanism 200, and second positioning mechanism 300 in this application can simplify the footprint of the stapler device 1000, save costs, and improve stapler efficiency. This application does not limit the number of stapler stations on the stapler mechanism 100; there can be one, two, three, or more stapler stations. This application provides an example of four stapler stations. The stapler stations on the stapler mechanism 100 can be arranged in a single row or multiple rows, and the arrangement can be along a straight line or along an arc; this application does not limit this arrangement.

[0093] like Figure 6As shown, in this embodiment of the application, the nail-separating mechanism 900 includes a sealing nail vibratory plate 910 disposed on one side of the frame. The sealing nail vibratory plate 910 is a precision vibratory plate, which uses vibration to convey the sealing nails. According to the equipment design capacity, it can be configured with multi-channel conveying to improve the efficiency of nail separation and nail picking. In addition, when arranging the various mechanisms, this application uses the second moving mechanism to drive the nailing mechanism 100 to pick up the sealing nails in the picking area of ​​the nailing mechanism 900. After that, the nailing mechanism 100 moves to the camera of the first positioning mechanism 200 and the sealing nails on the nailing station are photographed and positioned by the camera in sequence. The positional deviation between the sealing nail and the center of the suction head 29 is obtained by image processing technology. During the nail picking process, the second moving mechanism drives the second positioning mechanism 300 to move above the battery and the camera on the second moving mechanism takes a picture of the sealing opening at the top of the battery to obtain the positioning of the sealing opening on the fixture 140. Based on the positioning of the sealing nail on the nailing mechanism 100 and the positioning of the battery sealing opening on the fixture 140, the motion parameters of the first moving mechanism and the second moving mechanism are calculated. The first moving mechanism and the second moving mechanism drive the nailing mechanism 100 to move above the corresponding battery, and the nailing of the four batteries is completed sequentially or simultaneously.

[0094] This application embodiment also provides a nail-driving mechanism 500 to drive the acquisition mechanism 400 at each nail-driving station to perform individual up-and-down movements. For example... Figure 7-9 As shown, specifically, the acquiring mechanism 400 includes a lifting rod 11 arranged along the first direction Z, and the lifting rod 11 is provided with a suction head 29 for adsorbing the sealing nail; the nail-attaching driving mechanism 500 includes a driving unit 110 and a clamping unit 120, wherein the driving unit 110 includes a synchronous motor 12, a driving wheel 13 connected to the synchronous motor 12, and a driven wheel 14 connected to the driving wheel 13 via a synchronous belt 15, and the driving wheel 13 and the driven wheel 14 are arranged vertically along the first direction Z; the clamping unit 120 includes a pressure block 16 fixedly arranged on one side of the synchronous belt 15, and the pressure block 16 is fixedly connected to the lifting rod 11.

[0095] In this embodiment, the linear motion is driven by the upper nail drive mechanism 500 using a synchronous belt 15. The lifting rod 11 is fixedly mounted on the synchronous belt 15 by the clamping unit 120. The synchronous belt 15 is arranged vertically on both sides, and the pressure block 16 presses against one side of the synchronous belt 15. Figure 10 As shown, the synchronous motor 12 rotates and drives the synchronous belt to move. The synchronous belt 15 on one side drives the lifting rod 11 to move up and down. For example, when the synchronous motor 12 rotates forward, the lifting rod 11 moves upward and when the synchronous motor 12 rotates in reverse, the lifting rod 11 moves downward. The upper nail drive mechanism 500 can simplify the floor space, save costs, and improve the motion accuracy and control accuracy of the upper nail mechanism 100.

[0096] Among them, such as Figure 11-13 As shown, the clamping unit 120 includes a clamping plate 17 fixedly connected to the lifting rod 11. The clamping plate 17 is provided with a pressure block 16 at each of the upper nailing positions. The pressure block 16 includes a first pressure part 161 and a second pressure part 162 that are detachably connected. The first pressure part 161 and / or the second pressure part 162 are provided with pressure teeth 30 that contact the synchronous belt 15. The clamping unit 120 also includes two locking rings 18 fixedly connected to each of the lifting rods 11. The two locking rings 18 contact the upper surface and the lower surface of the clamping plate 17, respectively.

[0097] In the embodiments of this application, such as Figure 13 As shown, the clamping plate 17 is sleeved on the lifting rod 11 and pressed onto the clamping plate 17 by two locking rings 18 provided on the lifting rod 11. The clamping plate 17 is provided with a pressure block 16 fixedly connected to the synchronous belt 15. The pressure block 16 presses the synchronous belt 15 onto the pressure block 16 by two detachably connected first pressure parts 161 and second pressure parts 162. The pressure teeth 30 provided can improve the fixation degree of the clamping plate 17 and prevent slippage on the conveyor belt. The clamping plate 17 and the lifting rod 11 move up and down by the conveyor belt.

[0098] In this embodiment, as Figure 14 As shown, the locking ring 18 has an opening, and the tightening degree is adjusted by a horizontally arranged bolt to improve the fixing effect. The locking rings 18 on the upper and lower sides of the clamping plate 17 realize the positioning and clamping of the lifting rod 11, improving the movement accuracy. For example, the clamping plate 17 includes a first surface and a second surface arranged vertically. A first locking ring 167 is provided on the first surface, and a second locking ring 168 is provided on the second surface. Further, in order to improve the installation accuracy and fixing degree of the clamping plate 17 and the lifting rod 11, two rolling bearings, such as a first bearing 163 and a second bearing 164, are provided between the two locking rings 18 on the lifting rod 11. Figure 15 As shown, the clamping plate 17 has a first mounting hole 165 on the first surface and a second mounting hole 166 on the second surface. A stop is provided between the first mounting hole 165 and the second mounting hole 166. The first bearing 163 is installed in the first mounting hole 165. One end of the first bearing 163 is pressed by a first locking ring 167, and the other end of the first bearing 163 is pressed by the stop. The second bearing 164 is installed in the second mounting hole 166. One end of the second bearing 164 is pressed by a second locking ring 168, and the other end of the second bearing 164 is pressed by the stop.

[0099] Additionally, the nailing device 1000 includes a fixing plate 19 for fixing the acquiring mechanism 400 and the driving mechanism, such as... Figure 16 As shown, the fixed plate 19 is provided with at least one guide unit 150 for guiding the upper nailing mechanism 100. The guide unit 150 includes a guide plate 20 fixedly mounted on the fixed plate 19, and the guide plate 20 is provided with a guide sleeve 21 that slides with each of the lifting rods 11, such as... Figure 18 As shown.

[0100] The upper nailing device 1000 is fixedly mounted on the second slide block 32 of the second moving mechanism via the fixing plate 19. The synchronous motor 12, driving wheel 13, and driven wheel 14 of the driving mechanism are fixedly mounted on the fixing plate 19. The lifting rod 11 is guided by the guide unit 150 mounted on the fixing plate 19. The lifting rod 11 slides up and down in the guide sleeve 21. The guide sleeve 21 is provided with multiple contact edges 28 extending along the Z-axis. The contact edges 28 are slidably connected to the lifting rod 11. The contact edges 28 reduce the sliding friction between the lifting rod 11 and the guide sleeve 21, prevent the guide unit 150 from vibrating or deviating during movement, improve the movement accuracy, and increase the service life of the lifting rod 11 and the guide sleeve 21.

[0101] The fixing plate 19 is provided with mounting positions for the driving wheel 13 and the driven wheel 14. These mounting positions ensure that the driving wheel 13 and the driven wheel 14 are on the same vertical line, allowing the synchronous belt 15 to be vertically positioned along the Z-axis. The fixing plate 19 improves positioning and installation accuracy. The synchronous belt 15 is tensioned in the Z-axis direction, and the clamping mechanism is installed along the Z-axis travel of the synchronous belt 15. The motor's forward and reverse rotation drives the two sides of the synchronous belt 15 to move up and down, which in turn drives the lifting rod 11 to move up and down, thus enabling the nail removal and installation operations.

[0102] In the embodiments of this application, such as Figures 19-20 As shown, the guide sleeve 21 is fixedly connected to the guide plate 20 via fixing units 130 sleeved at both ends. The fixing unit 130 includes:

[0103] A bushing 22 is sleeved on the lifting rod 11, and the bushing 22 is provided with a limiting hole 23 for limiting the end of the guide sleeve 21;

[0104] A limiting bearing 24 is sleeved on the bushing 22, and a limiting platform 33 is provided on the bushing 22 for limiting one end of the limiting bearing 24.

[0105] A bearing cover 25 is disposed on the surface of the guide plate 20, the bearing cover 25 being used to limit the other end of the limiting bearing 24.

[0106] In this embodiment, the guide sleeve 21 is made of a wear-resistant material, such as stainless steel. By processing it separately, the installation and positioning accuracy can be improved. Both ends of the guide sleeve 21 are fixedly mounted on the guide plate 20 via bushings 22, limit bearings 24, and bearing covers 25. The guide plate also has limit mounting holes 34 that mate with the limit bearings 24. The limit mounting holes 34, limit platforms 33, and bearing covers 25 improve the fixing accuracy of the guide sleeve 21 and the movement accuracy of the lifting rod 11. In a specific configuration, the guide sleeve 21 has a keyway. The two bushings 22 are fixedly connected to the guide sleeve 21 via a mounting key. The bushings 22 and the bearing covers 25 are located at both ends of the limit bearings 24 to achieve the clamping and fixing of the limit bearings 24.

[0107] In the embodiments of this application, please continue to refer to Figure 8 The fixing plate 19 is provided with two guide units 150, and the clamping unit 120 is located between the two guide units 150. Each guide unit 150 is also provided with a guide post 26 corresponding to the upper nailing position. The clamping unit 120 is provided with a guide hole 27 that mates with the guide post 26. The guide units 150 on both sides of the clamping unit 120 provide limiting and guiding functions, and the guide post 26 further improves the movement accuracy of the lifting rod 11, preventing wobbling or offset during movement and improving multi-positioning accuracy.

[0108] In the embodiments of this application, such as Figure 9 and Figure 16 As shown, the fixing plate 19 is equipped with a sensing sensor 160 for positioning the drive mechanism and an adjustment unit 170 for adjusting the tension of the synchronous belt 15. The clamping mechanism is mounted on the synchronous belt 15, which is driven to move by the synchronous motor 12. The sensing sensor 160 can detect or control the motor parameters, thereby enabling the detection or control of the movement of the lifting rod 11. For example, the sensing sensor 160 can be a grating encoder for detecting motor speed or position. Different sensing methods or limiting methods can be used in different embodiments, and this application does not limit this.

[0109] In this embodiment, the tension of the timing belt 15 can be adjusted by the adjustment unit 170 disposed on the fixed plate 19, which also facilitates the maintenance and replacement of the timing belt 15. The adjustment unit 170 can be a manual adjustment unit 170. For example, the adjustment unit 170 includes a sliding groove disposed on the fixed plate 19 along the Z-axis direction. The driven wheel 14 is fixed in the sliding groove by bolts. The position of the driven wheel 14 can be freely adjusted by adjusting the bolts, so that the driven wheel 14 can fit against the timing belt 15 and the tension of the timing belt 15 can be adjusted.

[0110] Based on the same inventive concept, such as Figure 21 As shown, this application provides a battery sealing nail welding device, including a battery sealing nail mounting device 1000 as described above, and a cleaning device 2000, a flatness inspection device 3000, a pre-welding device 4000, a full-welding device 5000, and a post-welding inspection device 6000 disposed on the frame, wherein the mounting device 1000 is disposed between the cleaning device 2000 and the flatness inspection device 3000.

[0111] The cleaning device 2000 is used to perform a cleaning operation on the welding area of ​​the battery to be nailed.

[0112] The nailing device 1000 is used to perform a sealing nailing operation on the cleaned battery;

[0113] The planar detection device 3000 is used to perform a nailing detection operation on the nailed battery;

[0114] The pre-welding device 4000 is used to perform multi-point pre-welding operations on batteries that have already been nailed.

[0115] The full welding device 5000 is used to perform sealing nail welding operations on pre-welded batteries;

[0116] The post-weld inspection device 6000 is used to perform welding inspection operations on the welded batteries.

[0117] It is understood that the arrangement of the various mechanisms in this application is not limited to a linear arrangement, and various feasible structural forms can be adopted, such as a circular arrangement. In this application, a linear arrangement is used as an example for illustrative purposes. The sealing nail welding equipment provided in this application integrates the various functional devices used in the battery sealing nail welding process onto the same welding equipment. Specifically, it integrates functions such as pre-welding area cleaning, nail positioning, flatness detection, laser pre-welding / full welding, and post-welding inspection, realizing a standard process for cylindrical battery sealing nail welding. In different embodiments, one or more of the various functional devices in this application can be selected as needed, and this application is not limited in this regard.

[0118] like Figure 22 As shown, the battery sealing nail welding equipment includes a conveying device 7000 disposed on the frame along the second direction Y. The conveying device 7000 is used to convey the fixture 140 to a preset position. The conveying device 7000 includes a first linear motor 710, a first linear guide rail 720 disposed on both sides of the fixture 140, and a conveying platform 730 that slides with the first linear motor and the first linear guide rail. The fixture 140 is disposed on the conveying platform 730. Figure 23 As shown, the fixture 140 includes a battery tray 116 and a lifting mechanism 117 disposed below the battery tray 116. The battery tray 116 includes a plurality of placement holes 118, and the lifting mechanism 117 includes lifting mechanisms 117 corresponding to the plurality of placement holes 118.

[0119] According to the above-mentioned equipment functions, in this application, the jig 140 loaded with cylindrical batteries is directly transported to the operation position of each process by the conveying device 7000. The conveying device 7000 is composed of linear guide rails, linear motor modules, and a conveying platform. The conveying device 7000 is used to support the jig 140, transport the batteries to be produced into the work area, and realize movement in the X-axis direction. The linear motor module and the linear guide rails form a wide conveying device 7000. The linear motor module is controlled and driven by PLC, which provides power to the transfer module and can accurately run the position, moving to the corresponding position according to the PLC program instructions.

[0120] The jig 140 directly uses the tray 116 for feeding, eliminating the need for a robotic arm to pick up and place batteries, thus reducing loading time. In this application, the jig 140 consists of two parts: a cylindrical battery tray 116 and a lifting assembly. The jig 140 is designed for large-scale loading of cylindrical lithium batteries. The cylindrical battery tray 116 is used to place and position cylindrical cells. The tray 116 has multiple placement holes 118 for placing cylindrical batteries, allowing for equidistant alignment and positioning with a planar positioning accuracy of ±0.5mm. The parts in contact with the cells are made of non-metallic materials to maximize the protection of the product surface. It is understood that the number of placement holes 118 on the tray 116 is not limited in this application embodiment; it can be selected according to needs in different embodiments. The placement holes 118 can be arranged in a single row, single column, or multiple rows and columns. For example, the tray 116 can be used to load 8*8=64 battery products and perform sealing nail welding.

[0121] The lower lifting assembly is designed to work in conjunction with each process, enabling individual lifting of batteries, single-row lifting for overall positioning, or multi-row lifting. It is powered by an independent cylinder. The lifting mechanism 117 is fixed to the conveying device 7000 below, while the battery trays 116 are mounted on the lifting mechanism 117 and positioned by positioning guide pins. They can be manually removed. During operation, multiple cylindrical battery trays 116 are used alternately to achieve cyclic loading and unloading of materials during equipment operation.

[0122] The lifting mechanism 117 provided in this embodiment may include multiple lifting functions, such as a first-stage lifting mechanism 117 for individually lifting individual defective products detected during operation; a second-stage lifting mechanism 117 for simultaneously lifting a single row of batteries; and a third-stage lifting mechanism 117 for simultaneously lifting all batteries on the tray 116. This ensures consistent battery lifting in each process, especially ensuring that the top surface of the battery aligns with the surface of the welding fixture 140, thus ensuring consistent focal length during laser welding of multiple batteries. The appropriate mechanism can be selected or configured as needed in different embodiments.

[0123] In the embodiments of this application, such as Figure 24-25 As shown, the frame includes a base 111 and a cover 112. The base 111 includes a gantry frame disposed above the conveying device 7000. The gantry frame includes a second linear motor 113 and a second linear guide rail 114 arranged in parallel. The second linear motor 113 includes a plurality of slides 115 for driving the cleaning device 2000, the nail mounting device 1000, the plane detection device 3000, the pre-welding device 4000, the full welding device 5000, and the post-welding detection device 6000.

[0124] In practical implementation, the base 111 is assembled from welded steel components and sheet metal door panels. A horizontally arranged plate on the base 111 supports the conveyor device 7000. Double gantry linear motor modules are mounted on both sides of the plate for the Y-axis movement of each functional module. The gantry linear motor modules use high-precision linear motors and are equipped with six sets of slides 115 according to the functional modules, with a load capacity greater than 60KG and a running speed of 1M / S. By arranging multiple functional modules on the same electrode module, the footprint is reduced, and the process operation efficiency is improved. The machine cover 112 is made of aluminum profile and includes a human-machine interface touchscreen, laser display, laser protective window, and profile machine cover 112 itself; it provides safety protection for the laser, CCD, and moving mechanism inside the equipment, and also isolates the laser inside the equipment to prevent injury to external personnel. The doors around the machine cover 112 can be opened and closed, and a safety access control system is configured to prevent unauthorized opening of the doors during equipment operation. The aluminum profile machine cover 112 is the main protective and isolation component for the upper functional area of ​​the equipment.

[0125] The gantry frame also includes a plurality of crossbeams disposed between the second linear motor 113 and the second linear guide rail 114. The crossbeams are provided with a second cleaning moving mechanism 220 for driving the cleaning device 2000 to move along the second direction Y, a second nailing moving mechanism 700 for driving the nailing device 1000 to move along the second direction Y, a second plane detection moving mechanism 320 for driving the plane detection device 3000 to move along the second direction Y, a second pre-welding moving mechanism 420 for driving the pre-welding device 4000 to move along the second direction Y, a second full-welding moving mechanism 520 for driving the full-welding device 5000 to move along the second direction Y, and a second post-welding detection moving mechanism 620 for driving the post-welding detection device 6000 to move along the second direction Y.

[0126] The crossbeam is provided with a first cleaning moving mechanism 230 for driving the cleaning device 2000 to move along the first direction Z, a first nailing moving mechanism 600 for driving the nailing device 1000 to move along the first direction Z, a first plane detection moving mechanism 330 for driving the plane detection device 3000 to move along the first direction Z, a first pre-welding moving mechanism 430 for driving the pre-welding device 4000 to move along the first direction Z, a first full-welding moving mechanism 530 for driving the full-welding device 5000 to move along the first direction Z, and a first post-welding detection moving mechanism 630 for driving the post-welding detection device 6000 to move along the first direction Z.

[0127] In this application, the various functional modules are arranged using crossbeams mounted on a double-gantry linear motor module. Each crossbeam is fixedly connected to the slide block 115 of the double-gantry linear motor module, enabling each crossbeam to move linearly along the second direction Y. Each crossbeam is equipped with a precision moving mechanism that moves in the first direction Z and the third direction X, allowing each functional module to be individually driven to move linearly along a preset direction, thus achieving a preset function. In this application, the first moving mechanism is a Z-axis moving mechanism, the second moving mechanism is a Y-axis moving mechanism, and the third moving mechanism is an X-axis moving mechanism. The functions of each module are described in detail below.

[0128] like Figure 26 As shown, the cleaning device 2000 includes a laser cleaning head 210 and a laser dust collection hood 220. The laser cleaning head is moved by an X-axis moving mechanism 230 and a Z-axis moving mechanism 240. The laser cleaning head 210 cleans the surface of the liquid injection port at the top of the battery within the fixture 140, removing the oxide layer from the product surface. The laser-cleaned liquid injection port area improves the weld quality of the sealing nail welding during welding, reducing welding defects such as bursts and blackening. During the laser cleaning of the liquid injection port surface, the laser dust collection hood in the work area uses an exhaust device to collect the generated fumes.

[0129] The nailing device 1000 is equipped with an X-axis moving mechanism 700 and a Z-axis moving mechanism 500, which move the nailing mechanism 100 and the second positioning mechanism 300. The nailing mechanism 100 uses four sets of independent lifting suction heads 29. After the suction head 29 picks up the sealing nail in the material picking area of ​​the nailing mechanism 900, it first moves to the camera of the first positioning mechanism 200. The X-axis drives the suction head 29 to be photographed and positioned by the first positioning mechanism 200 in sequence. The positional deviation between the sealing nail and the center of the suction head 29 can be quickly obtained by image processing technology. The suction head 29 then moves to the top of the battery fixture 140. During the movement, the second positioning mechanism 300 takes a picture of the sealing opening at the top of the battery. The image processing technology calculates the positional deviation of the sealing opening center. The image processing technology feeds back the position data collected by the first positioning mechanism 200 and the second positioning mechanism 300 to the main control program of the equipment, and then controls the movement of the X / Y moving mechanism to move the suction head 29 to the battery nailing position, and completes the sealing of four batteries in sequence.

[0130] like Figure 27 As shown, the planar inspection device 3000 includes a 3D line scan camera 310, which is moved by the X-axis moving mechanism 320 and the Z-axis moving mechanism 330. The 3D line scan camera scans the top of the battery with the sealing nail installed. The 3D camera calculation software processes the data and provides corresponding data, which can be used to determine the front and back, defects, and flatness information of the sealing nail. The device stores product OK (good) / NG (bad) information. NG products are not welded in subsequent welding processes, while OK products are welded normally in subsequent processes.

[0131] like Figure 28 As shown, the pre-welding device 4000 is a galvanometer laser welding device, including a galvanometer laser head 410 and a CCD system 420 coaxially arranged with the galvanometer laser head 410. The galvanometer laser head 410 is moved by the X-axis moving mechanism 430 and the Z-axis moving mechanism 440. The field lens range of the galvanometer laser head 410 is 150mm*150mm. Combined with laser galvanometer welding control software, the product within the field lens range can be imaged by CCD. The software will locate the welding area, and then the galvanometer laser will weld along the welding contour. The laser system can store 100 welding recipes according to process requirements, which can be automatically called by the main control program to realize automated welding. It can realize large-area pre-spot welding of single batteries and multiple battery arrays (2*2, 3*3, etc.). The galvanometer laser head 410 is equipped with a nitrogen air knife and a dust collection device to provide gas protection for the welding area and extract the welding fumes.

[0132] like Figure 28As shown, the full-welding device 5000 is a galvanometer laser welding equipment, including a galvanometer laser head 510 and a CCD system 520 coaxially arranged with the galvanometer laser head 510. The galvanometer laser head 510 is moved by the X-axis moving mechanism 530 and the Z-axis moving mechanism 540. The field lens range of the galvanometer laser head 510 is 150mm*150mm. Combined with the laser galvanometer welding control software, the product within the field lens range can be imaged by CCD. The software will locate the welding area, and then the galvanometer laser will weld along the welding contour. The laser system can store 100 welding recipes according to process requirements, which can be automatically called by the main control program to realize automated welding. It can realize large-area pre-spot welding of single batteries and multiple battery arrays (2*2, 3*3, etc.). The galvanometer laser head 510 is equipped with a nitrogen air knife and a dust collection device to provide gas protection for the welding area and extract the welding fumes. The configurations of the full welding and pre-welding devices 4000 are basically the same, the difference being that the full welding device welds the entire weld seam of the sealing nail.

[0133] like Figure 29 As shown, the post-weld inspection device 6000 includes a 3D line scan camera 610 and a 2D camera 620. The 3D line scan camera 610 and the 2D camera 620 are mounted and moved by the X-axis moving mechanism 630 and the Z-axis moving mechanism 640. The 3D line scan camera 610 and the 2D camera 620 can detect various defects in the sealing nail weld through AI vision algorithm software: pinhole diameter ≥0.2mm, burst points, pits, molten beads (size ≥0.2mm), missing welds or broken welds (≥1mm), weld line offset (≥0.2mm), over-welding (welds with black or yellow smoke are unacceptable), and crack detection accuracy: width ≥0.02mm, depth ≥0.2mm, length ≥0.5mm. The defective products are selected and the defect information is stored in the equipment. The equipment can be equipped with a defective product sorting device at the back end. According to the defective product information provided by the sealing nail welding equipment, the defective batteries are taken out and stored in separate areas for subsequent manual processing. Good products are paired and placed on trays before entering the next process equipment.
