Description

[0002] The manufacturing of batteries includes three main links: electrode manufacturing, battery cell assembly, and formation testing. The battery cell assembly link mainly involves major processes such as tab welding, top cover welding, and battery cell shelling.

[0003] In the conventional process, in the lug welding process, the battery cell is placed in a fixture in a side-lying form, and the lug of the battery cell extends from one side and is connected to the adapter plate in the fixture by welding. In the top cover welding process, the transfer mechanism transfers the welded battery cell and the adapter plate to the top cover welding fixture. At this time, the battery cell is still placed in the fixture in a side-lying form. In the above-mentioned lug welding process and top cover welding process, the adapter plate and the top cover are both placed in the fixture, and the end face of the fixture provides support for the adapter plate and the top cover. The adapter plate and the lug, or the adapter plate and the top cover are pressed together by the welding protection mechanism to assist in the welding operation. Therefore, in the conventional process, in order to meet the quality requirements of welding, it is only necessary to adjust the fixture used to place the adapter plate and the top cover in advance to avoid the occurrence of welding problems such as cold welding.

[0004] In a new process, whether it is the tab welding process or the top cover welding process, the battery cell is placed in a vertical state in the fixture. During the welding process of the tab and the adapter, or the adapter and the top cover, the adapter and the top cover are mainly supported by the end faces of the battery cell. Since the battery cell itself is not a rigid structure, the supporting end faces of the battery cell may have flatness problems, that is, one side of the battery cell placed in the fixture is higher and the other side is lower. This problem will directly affect the quality of the battery cell assembly process, resulting in poor consistency of the produced batteries, and may even cause product safety issues.

[0005] From the above, it can be seen that for batteries using vertical welding, the battery cells placed on the fixture have a problem of poor flatness, which in turn affects the production quality of the battery. Summary of the invention

[0047] The frame 10 includes a top plate and a plurality of legs arranged at the bottom of the top plate.

[0048] Specifically, the battery manufacturing equipment used in the present application can be applied to a new process for vertical welding of the battery cell 40. During the vertical welding of the battery cell 40, the area 411 to be welded remains located on the top side of the battery cell 40. The present application clamps and fixes the mounting fixture 30 of the battery cell 40 through the battery manufacturing equipment, thereby ensuring the flatness of the battery cell 40. The welding part 610 can be used to directly perform welding operations on the area 411 to be welded on the top of the vertical battery cell 40. The operation is simple and the area 411 to be welded is formed as a horizontal surface. This is conducive to improving the uniformity of welding and thus improving the accuracy of welding, which is conducive to ensuring the production quality of the battery. The battery manufacturing equipment of the present application overcomes the problem that there is no welding equipment suitable for vertical welding of the battery cell 40 in the prior art and the problem that the uneven area 411 to be welded of the battery cell 40 affects the welding quality of the battery cell 40.

[0052] The present application adopts an installation jig 30 to install and limit the battery cell 40, thereby pre-fixing the battery cell 40, and uses the technical means of lifting and moving the jig through the lifting mechanism 20 to keep the battery cell 40 upright, thereby avoiding the phenomenon that the lifting mechanism 20 directly contacts the battery cell 40 and causes damage to the battery cell 40. At the same time, the technical means of installing the jig 30 facilitates the coordination and positioning with the lifting mechanism 20, simplifies the operation, and is conducive to improving the efficiency of manufacturing the battery cell 40.

[0053] In this embodiment, the mounting jig 30 has a mounting cavity with a top opening, the battery cell 40 is vertically placed inside the mounting cavity, and the area to be welded 411 on the top of the battery cell 40 is exposed from the top opening of the mounting jig 30.

[0074] The elastic member 2344 may be a plate structure capable of elastic deformation, or may be a spring.

[0075] Specifically, the setting of the pad 2343 is used to provide an installation position for the installation of the lower clamping plate 2342 , and the setting of the pad 2343 can also increase the contact area with the elastic member 2344 .

[0076] In this embodiment, a structural setting is adopted in which an elastic member 2344 is set between the pad 2343 and the lower clamping plate 2342. The elastic member 2344 has a buffering clamping effect. When the upper clamping plate 2341 and the lower clamping plate 2342 clamp the installation fixture 30, the elastic member 2344 has the function of buffering external force and can be fine-tuned through elastic deformation to achieve a horizontal correction effect, so as to ensure that the installation fixture 30 is horizontally clamped at the clamping structure 234.

[0077] In this embodiment, the clamping structure 234 further includes a positioning pin 2345, which is disposed on the bottom plate 211 and extends along the height direction of the frame body 210, and the positioning pin 2345 penetrates the pad 2343 and is slidably connected to the pad 2343. The positioning pin 2345 has a limiting effect, so that the pad 2343 and the lower clamping plate 2342 can be partially or completely fine-tuned along the height direction of the frame body 210, so as to avoid the pad 2343 and the lower clamping plate 2342 from being offset in the horizontal plane direction.

[0078] In this embodiment, the lifting assembly also includes a display and a controller, which are arranged on the frame 210. The controller is connected to the display, the pressure sensor 250 and the lifting drive 220 by signals to display the real-time value of the pressure through the display.

[0079] like Figures 7 to 10 As shown, the welding positioning mechanism 50 also includes a buffer structure, which is arranged between the pressing mechanism and the reference plate 501. The setting of the buffer structure has the effect of buffering external force, and the setting of the buffer structure also has the effect of fine-tuning, so as to ensure that the opening of the welding channel 511 of the pressing mechanism is completely pressed against the top cover assembly on the top of the battery cell 40, that is, the peripheral edge of the opening of the welding channel 511 is completely in contact with the top of the top cover assembly, so as to ensure that the battery cell 40 is limited in the subsequent welding operation, and avoid shaking or offset that affects the welding accuracy.

[0080] Specifically, the buffer structure is a spring or a gasket that can undergo elastic deformation.

[0081] In this embodiment, the reference plate 501 is mounted on the top plate of the frame 10 by a plurality of fasteners, and the plurality of fasteners can independently adjust the distance between the reference plate 501 and the top plate of the frame 10. The fasteners are bolts, and the distance between the reference plate 501 and the top plate of the frame 10 can be adjusted by turning the bolts, thereby adjusting and ensuring the flatness of the reference plate 501 during installation; at the same time, the structural setting of the fasteners also facilitates the disassembly of the reference plate 501. When a different type of mounting fixture 30 is required, the reference plate 501 and the holding mechanism can be replaced. The overall structure is simple and has a wide range of applications.

[0082] like Figures 7 to 10 As shown, the pressing mechanism includes a first pressing plate 510 and a second pressing plate 520 arranged on the side of the first pressing plate 510 away from the reference plate 501, the first pressing plate 510 has a first through hole 512, the second pressing plate 520 has a second through hole 521 connected to the first through hole 512, the first through hole 512 and the second through hole 521 form a welding channel 511 on the pressing mechanism.

[0083] The present application adopts a method of forming a welding channel 511 on the pressing mechanism, so that when the pressing mechanism abuts against the area to be welded 411, the welding operation can be performed on the area to be welded 411 through the welding channel 511, so as to achieve the effect of non-interference between welding and positioning. The setting of the welding channel 511 of the present application provides a welding space for the welding head, which is beneficial to improving the welding accuracy; the setting of the welding channel 511 realizes that the welding action is carried out inside the welding channel 511, which is beneficial to avoid the phenomenon of welding slag splashing, and also avoids the welding process from being easily affected by the outside world, plays a protective role, and further improves the welding quality.

[0084] Wherein, along the length direction of the first pressing plate 510 , two second pressing plates 520 are arranged at intervals on the first pressing plate 510 .

[0085] The length direction of the first pressing plate 510 is Figure 8 In the X direction shown, the width direction of the first pressing plate 510 is Figure 8 In the Y direction shown, the height direction of the first pressing plate 510 is Figure 8 The Z direction is shown.

[0086] like Figures 7 to 10 As shown, the area of ​​the end of the second pressing plate 520 of the present application connected to the first pressing plate 510 is larger than the area of ​​the end of the second pressing plate 520 away from the first pressing plate 510 .

[0087] Specifically, the area of ​​the end where the second pressure plate 520 is connected to the first pressure plate 510 is larger than the area of ​​the end of the second pressure plate 520 away from the first pressure plate 510, which is beneficial to improving the connection strength between the second pressure plate 520 and the first pressure plate 510; the area of ​​the end of the second pressure plate 520 away from the first pressure plate 510 needs to be suitable for cooperating with the top of the pole assembly 413, so as to achieve abutment with the top surface of the pole assembly 413 to limit the pole assembly 413. In actual applications, the area of ​​the pole assembly 413 is relatively small, so the area of ​​the end of the second pressure plate 520 away from the first pressure plate 510 is small. At the same time, the end of the second pressure plate 520 away from the first pressure plate 510 can avoid occupying the space on the pole assembly 413, thereby improving the welding accuracy.

[0088] In this embodiment, the pressing mechanism further includes a connecting piece, and the first pressing plate 510 and the second pressing plate 520 are connected by the connecting piece, wherein the connecting piece can buffer the external force by elastic deformation, and the connecting piece can be a spring or an elastic gasket. Specifically, the cooperation between the second pressing plate 520 and the connecting piece can realize a floating setting relative to the first pressing plate 510, and then when pressing the pole assembly 413, the second pressing plate 520 can realize a complete abutment with the pole assembly 413 through a floating setting, further improving the stability of the pole assembly 413 during welding.

[0089] In this embodiment, the opening area of ​​the welding channel 511 on the holding mechanism toward the reference plate 501 is larger than the opening area away from the reference plate 501. The opening area of ​​the welding channel 511 formed by the first pressing plate 510 and the second pressing plate 520 gradually increases in the direction away from the pole assembly 413 to form a flared structure. The flared structure can better adapt to the welding head of the welding equipment, ensuring that the welding head can accurately enter the area to be welded 411, thereby improving the accessibility and accuracy of welding. The setting of the flared structure facilitates the welding operation and provides a wider working space for the welding equipment, thereby improving the convenience and efficiency of welding.

[0090] In this embodiment, the first via hole 512 and the second via hole 521 are connected to form a welding channel 511, and the center lines of the first via hole 512 and the second via hole 521 are arranged in a colinear manner to avoid the phenomenon of interference welding between the inner wall surfaces of the first via hole 512 and the second via hole 521. The welding channel 511 formed by the connection of the first via hole 512 and the second via hole 521 simplifies the structural setting, ensures that the welding head can accurately enter the area to be welded, and then weld. During the welding process, the accurate entry of the welding head and the accessibility of the area to be welded ensure the welding quality and efficiency, while reducing the risk of component displacement and avoiding the performance problems of the battery caused by poor welding.

[0091] In this embodiment, the pressing mechanism is used for welding the pole ear and the adapter plate, and can also be used for welding the pole assembly 413 and the adapter plate pole 414. Since the structure of the pole ear and the adapter plate is different from the structure of the pole assembly 413 and the adapter plate pole 414, the specific structure of the pressing mechanism is not exactly the same when applied to different welding scenarios.

[0092] Specifically, due to the different specific structures of welding, the structure of the second pressure plate 520 of the pressing mechanism is different. When the pressing mechanism is used for welding the pole ear and the adapter plate, the opening of the abutting end of the second pressure plate 520 is square. The welding scenario at this time does not involve the pole assembly 413, so there is no need to set a positioning block 530 for positioning the pole assembly 413; when the pressing mechanism is used for the welding scenario of the pole assembly 413 and the adapter plate pole 414, a positioning block 530 needs to be set to improve the welding efficiency.

[0093] In this embodiment, when the pressing mechanism is used for welding the pole tab and the adapter, the top cover assembly includes the adapter, the top of the battery cell 40 has a pole tab, the adapter and the pole tab are at least partially overlapped, and the bottom of the second pressure plate 520 of the pressing mechanism abuts against the adapter and the pole tab, forming a welding area 411 between the adapter and the pole tab, and the welding part 610 welds the adapter and the pole tab at the welding area 411 through the welding channel of the pressing mechanism.

[0094] In this embodiment, when the pressing mechanism is applied to the welding of the pole assembly 413 and the adapter pole, the top cover assembly includes the adapter and the battery top cover 410, the adapter has the adapter pole 414, the battery top cover 410 includes the cover plate 412 and the pole assembly 413 arranged on the cover plate 412, the adapter pole 414 penetrates the pole assembly 413, the bottom of the second pressing plate 520 of the pressing mechanism abuts against the peripheral edge of the pole assembly 413, and the area where the adapter pole 414 penetrates the pole assembly 413 forms a weld, and the weld is the area to be welded 411. The pole assembly 413 is a directional sheet structure, so the bottom end of the second pressing plate 520 forms a circular opening structure to be suitable for the structure of the pole assembly 413, so as to facilitate pressing on the pole assembly.

[0095] Among them, two pole assemblies 413 are arranged on the cover plate 412, one pole assembly 413 is a positive pole, and the other pole assembly 413 is a negative pole. Both pole assemblies 413 are pole sheet structures, which facilitates the installation of the pole assembly 413 into the inside of the pole installation groove on the cover plate 412, thereby realizing the positioning installation of the pole assembly 413.

[0096] A positioning block 530 is disposed on the outer side of each pole assembly 413 , and the positioning block 530 limits the pole assembly 413 .

[0097] The positioning block 530 abuts against the outer portion of the pole assembly 413 protruding from the pole installation groove, thereby positioning the pole assembly 413 .

[0098] like Fig.14 As shown, the present application adopts a structure arrangement in which the second pressing plate 520 and the positioning block 530 cooperate. In the process of welding the polar column assembly 413, it is necessary to ensure that the top end face of the polar column assembly 413 and the top end face of the adapter plate polar column 414 have a height difference (i.e. Fig.14 The height difference H) in the diagram remains consistent. To ensure the consistency of the step difference, the second pressing plate 520 presses the pole assembly 413 in the height direction of the pole assembly 413 to ensure that the pole assembly 413 is positioned relative to the adapter plate pole 414 in the height direction. The positioning block 530 limits the pole assembly 413 in the width direction of the pole assembly 413 to ensure the center position of the pole assembly 413 relative to the adapter plate pole 414, thereby avoiding the poor center position of the pole assembly 413 and the adapter plate pole 414. The impact of the second pressing plate 520 on the holding effect of the pole assembly 413 leads to poor consistency of the step difference between the pole assembly 413 and the adapter plate pole 414.

[0099] The top of the adapter pole 414 is located on the upper side of the top of the pole assembly 413. The top end surface of the pole assembly 413 and the top end surface of the adapter pole 414 form a step difference in height direction. The height H of the step difference satisfies 0-1mm, and preferably H is 0.3mm.

[0100] It should be noted that when detecting the step difference, Fig.15 The height of the step difference is detected in the eight directions indicated by the arrows of the positive pole and the negative pole, so as to detect the step difference in real time, thereby facilitating the consistency of the step difference. Specifically, the height of the step difference can be detected by the sensor 830 of the detection component 80, and compared with the preset step difference to determine whether the preset welding quality is achieved.

[0101] like Fig.11 As shown, the battery manufacturing equipment further includes a detection assembly 80 , and the detection assembly 80 includes a first driving member 810 , a fixing plate 820 and a sensor 830 .

[0102] The first driving member 810 is a motor or a slide cylinder, and the sensor 830 is a defocus sensor. The defocus sensor is a sensor that determines position information by calculating the displacement based on the information reflected after the laser is emitted and contacts an object.

[0103] The first driving member 810 is arranged on the frame 10, the fixing plate 820 is arranged at the driving end of the first driving member 810, and the sensor 830 is arranged on the fixing plate 820 for welding detection. The first driving member 810 drives the sensor 830 to move toward or away from the area to be welded 411 through the fixing plate 820.

[0104] Among them, the fixed plate 820 is used to provide installation for the sensor 830, and the first driving member 810 drives the fixed plate 820 to slide along the frame 10, so that the first driving member 810 drives the fixed plate 820 to be set toward or away from the welding area 411 to detect welding through the sensor 830.

[0105] Specifically, the frame 10 has a slide rail, and the fixed plate 820 is slidably arranged on the inner wall of the slide rail. Under the driving action of the first driving member 810, the fixed plate 820 and the sensor 830 reciprocate along the extension direction of the slide rail. When the sensor 830 is in the extended position, it is used to detect the welding quality. When the sensor 830 is in the retracted position, it is used to avoid the welding member 610 to avoid affecting the execution of the welding action. The sensor 830 realizes flexible movement through the setting of the first driving member 810, improves the flexibility of the structure, and can detect the welding quality through the sensor 830, which is conducive to realizing remote real-time monitoring of the welding situation, without the need for manual on-site inspection, and reduces safety risks.

[0106] The positioning block 530 abuts against the outer portion of the pole assembly 413 protruding from the pole installation groove, thereby positioning the pole assembly 413 .

[0107] Specifically, the welding positioning device of the present application adopts a structural setting in which a pressing mechanism and a positioning block 530 cooperate. During the welding process of the battery top cover 410, the positioning block 530 and the pressing mechanism can accurately position the pole assembly 413 in the battery top cover 410, ensuring the stability of the pole assembly 413 during the welding process, avoiding displacement during welding, and thus improving the welding quality.

[0108] Furthermore, after the positioning block 530 abuts against the pole assembly 413, it is fixed to the frame 10 of the battery manufacturing equipment by fasteners, so that the positioning block 530 is fixed to ensure that the positioning block 530 remains in abutment with the pole assembly 413. The end of the positioning block 530 in the present application facing the pole assembly 413 is the abutment end 531, and the abutment end 531 has two abutment portions 5312 spaced apart along the length direction of the mounting plate 201, and an avoidance opening 5313 is formed between the two abutment portions 5312, and the abutment portion 5312 abuts against the pole assembly 413. The structural setting of the positioning block 530 using two abutment portions 5312 can be applied to positioning pole assemblies 413 of different shapes, which is conducive to improving the scope of use; at the same time, the structural setting of the avoidance opening 5313 formed between the two abutment portions 5312 can also reduce the space occupied and avoid affecting the pressing effect of the pressing mechanism.

[0109] like Figures 7 to 10 As shown, the side of the positioning block 530 away from the mounting plate 201 along the thickness direction of the mounting plate 201 has a protrusion 540, and the protrusion 540 is arranged on the end of the positioning block 530 away from the pole assembly 413. The cover plate assembly includes a cover plate 412 and a pole assembly 413 arranged on the cover plate 412, and the protrusions 540 are abutted on both sides of the cover plate 412 along the width direction of the mounting plate 201.

[0110] Specifically, when the pole assembly 413 is placed on the cover plate 412, the limit block 270 moves toward the pole assembly 413 and abuts against the pole assembly 413, and both sides of the cover plate 412 abut against the protrusion 540. Such a design can further limit the displacement of the pole assembly 413 during the welding process and ensure the welding accuracy.

[0111] In this embodiment, the structure of the protrusion 540 is used to clamp the limiting cover plate 412, and the abutment portion 5312 on the positioning block 530 abuts against the limiting pole assembly 413. The protrusion 540 on the positioning block 530 limits the cover plate 412, and thus the positioning block 530 has the effect of limiting the pole assembly 413, which is beneficial to ensure the installation accuracy of the overall structure of the pole assembly 413.

[0112] In this embodiment, the battery manufacturing equipment also includes a dust suction component 70, which includes a dust removal duct 710 and a fan. The dust removal duct 710 is arranged on one side of the top of the reference plate 501. The suction end of the dust removal duct 710 is connected to the welding channel 511, and the fan is connected to the dust removal duct 710 to provide negative pressure to the interior of the dust removal duct 710.

[0113] Among them, there are two dust suction pipes, which are arranged corresponding to the two welding channels 511 to collect the welding slag in the welding area 411 in the two welding channels 511. The fan and the dust suction pipe are arranged one by one to facilitate the two dust suction pipes to perform independent dust suction work.

[0114] During the welding process, welding slag is generated, so the dust suction component 70 is provided to absorb the welding slag to avoid problems affecting the welding accuracy. The fan provides negative pressure for the dust removal pipe 710, so that the welding slag is absorbed into the dust removal pipe 710 under the action of the negative pressure, and the provision of the dust removal component is conducive to improving the cleanliness of the overall device.

[0115] In this embodiment, the battery manufacturing equipment also includes a second driving member 620 and a welding movable frame 630. The second driving member 620 is a motor or a cylinder. The second driving member 620 is arranged on the frame 10. The second driving member 620 is driven and connected to the welding member 610. The welding movable frame 630 is arranged on the frame 10. The welding member 610 is slidably arranged on the welding movable frame 630. The welding member 610 generates laser for laser welding.

[0116] The welding part 610 is a galvanometer, which is used to emit laser for laser welding.

[0117] In this embodiment, the welding piece 610 is suitable for welding the pole ear and the adapter plate and welding the adapter plate pole 414 on the adapter plate and the pole assembly 413 .

[0118] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0119] The battery manufacturing equipment used in this application can be applied to a new process for vertical welding of the battery cell 40. During the vertical welding of the battery cell 40, the area 411 to be welded remains on the top side of the battery cell 40. This application clamps and fixes the mounting fixture 30 of the battery cell 40 through the battery manufacturing equipment to ensure the flatness of the battery cell. The welding part 610 can be used to directly perform welding operations on the area 411 to be welded on the top of the vertical battery cell 40. The operation is simple and the area 411 to be welded is formed into a horizontal structure, which is conducive to improving the uniformity of welding and thus improving the accuracy of welding, and thus helping to ensure the production efficiency of the battery. The battery manufacturing equipment of this application overcomes the problem that there is no welding equipment suitable for vertical welding of the battery cell 40 in the prior art and the problem that the unevenness of the battery cell 40 affects the quality of battery welding.

[0120] The present application adopts a lifting mechanism 20 to support the installation fixture 30, and the welding positioning mechanism 50 abuts against the top cover assembly on the top of the battery cell 40, thereby doubly positioning the battery cell 40 in the height direction, which is beneficial to ensure the stability of the battery cell 40 during the welding process, and thus helps to improve the welding accuracy and avoid the phenomenon of affecting the welding quality due to shaking or deviation of the battery cell 40 during the welding process.

[0121] The present application adopts an installation jig 30 to install and limit the battery cell 40, thereby pre-fixing the battery cell 40, and uses the technical means of lifting and moving the jig through the lifting mechanism 20 to keep the battery cell 40 upright, thereby avoiding the phenomenon that the lifting mechanism 20 directly contacts the battery cell 40 and causes damage to the battery cell 40. At the same time, the technical means of installing the jig 30 facilitates the coordination and positioning with the lifting mechanism 20, simplifies the operation, and is conducive to improving the efficiency of manufacturing the battery cell 40.
