[0003] This invention aims to solve the technical problems existing in the prior art and provides a glue-coated solar cell string welding machine. It can automate the welding of solar cell strings in the glue-coating process, achieving functions such as automatic tape production and pulling, precise alignment and positioning of cell loading and transmission, camera-based digital alignment and correction for gripping and placement, and reusable clamps. With advantages such as high-speed loading and unloading, dense grid wire sorting, alternating double-claw tape pulling, precise control of tape bending position, and hot air circulation in the curing oven, it solves various problems existing in the prior art while meeting production cycle and efficiency requirements. The machine has good overall operational stability and environmental safety, and can greatly improve product quality and the economic benefits of the string welding industry.

[0004] The technical solution of the present invention is: a glue-applying battery cell string welding machine, comprising a tape supply mechanism, a tape making mechanism, a tape pulling mechanism, a glue pressing mechanism, a curing oven mechanism, a curing conveyor line mechanism, a battery cell loading and handling mechanism, a battery cell handling fork mechanism, a robot handling mechanism, a pressure fixture conveying mechanism, a pressure fixture recycling mechanism, a string cutting mechanism, and an EL detection mechanism;

[0005] After the welding wire of the feeding mechanism is inserted into the belt making mechanism, it is clamped and fixed by the belt pulling mechanism. The belt making mechanism performs bending and cutting actions and feeds the welding wire a certain distance. After the belt pulling mechanism clamps and pulls out the required length of two half-pieces of welding wire, the belt making mechanism repeats the aforementioned actions to cut the welding wire pulled out by the belt pulling mechanism, and at the same time prepares for the next belt pulling.

[0006] The tape-making mechanism and the tape-pulling mechanism are jointly mounted on the mounting plate. The tape-making mechanism includes a tape-threading mechanism, a bending mechanism, a tape-feeding power mechanism, and a first cutting mechanism. The welding wire passes through the tape-threading mechanism into the bending mechanism. The tape-feeding power mechanism is connected to the bending mechanism to drive the bending mechanism to move and send the cut end of the welding wire a certain distance out of the end of the first cutting mechanism. The tape-pulling mechanism includes an inner tape-pulling handle and an outer tape-pulling handle respectively mounted on the linear motor moving module, as well as a tape-supporting mechanism. The inner and outer tape-pulling handles can pull the tape up and down alternately. After the pulled welding wire is cut, the tape-supporting mechanism supports the tail end of the welding wire.

[0007] The battery cell loading and handling mechanism moves the battery cells from station one to station two of the battery cell handling fork mechanism. At the same time, the pressing and conveying mechanism conveys the pressing and conveying mechanism. The battery cells and pressing and conveying mechanism are aligned and converge to the handling station of the robot handling mechanism. The robot handling mechanism takes pictures for inspection and then grabs the battery cells and pressing and conveying mechanism.

[0008] The battery cell transport fork mechanism includes a rear transport fork and a front transport fork. Both the input end of the rear transport fork and the output end of the front transport fork are equipped with battery cell alignment mechanisms. Each transport fork includes a fixed fork and a movable fork. Multiple battery cells can be transported synchronously through the multiple lifting and forward movement of the movable fork. A battery cell loading and transport mechanism is set between the two transport forks for transferring battery cells. A pressure conveying mechanism transports the pressure from opposite directions. The robot transport mechanism includes a camera imaging and detection mechanism, a robot, a pressure and battery cell gripper mechanism, and a second vacuum generator. After the camera imaging and detection mechanism takes pictures of the battery cells and pressure, the robot drives the pressure and battery cell gripper mechanism to descend to a designated position for gripping based on the photographic results. The second vacuum generator provides suction force for the pressure and battery cell gripper mechanism to pick up the battery cells.

[0009] The wire pulling mechanism pulls the welding wire to the welding wire battery cell assembly station of the curing conveyor mechanism to perform a straightening and tightening action. Then, the robot handling mechanism aligns the pressure plate and battery cell and places them on the welding wire. The first pressure plate presses the front section of the welding wire without air, and the battery cell is then pressed on the rear section of the welding wire in sequence. Then, the previous action is repeated. The battery cell and pressure plate flow to the handling station. The robot handling mechanism takes pictures and detects, grabs and waits. The feeding, making and pulling mechanism produces two half-lengths of welding wire and pulls them above the battery cell placement position in the first step. At this time, the pressure plate and battery cell are aligned and placed again. The pressure plate presses the welding wire above the first battery cell, and the battery cell in sequence presses the rear section of the welding wire. The above actions are repeated to produce a continuous battery string assembly.

[0010] The glue pressing mechanism is located at one end of the curing conveyor mechanism, and the curing oven mechanism is located above the curing conveyor mechanism. The battery string assembly flows forward through the curing conveyor mechanism. Before entering the curing oven mechanism, the glue is discharged by pressing the pressure plate through the glue pressing mechanism. After curing in the curing oven mechanism, the battery string flows out, and the pressure plate is transported by the pressure plate recycling mechanism to the pressure plate conveyor mechanism for reuse.

[0012] The cured battery strings flow into the string cutting mechanism, which cuts the battery strings at the string spacing to form finished battery strings.

The module gripping and rotating mechanism is installed on the finished product transverse transfer module and is driven by the finished product transverse transfer module to move above the battery string. The battery string on the cylinder gripping and rotating mechanism is picked up and rotated 90° for manual inspection.

[0021] Furthermore, the power-on gripper mechanism described in this invention takes a picture through the EL detection dark box below at the moment of power-on detection to detect whether the current in the battery string is flowing. On one side of the feeding conveyor line, there is also a discharging conveyor line and a waste line. OK products are discharged through the discharging conveyor line, and NG products are transported to the waste line.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1) This invention features a linear layout and a U-shaped flow of the press, with two channels for process implementation. The upper channel is for the convergence of the press and the battery cells, while the right half of the lower channel is for welding wire fabrication, and the left half is for assembling and curing the battery cells and welding wire into strings. The battery cells are transported using a forklift, with two sets of alignment structures for coarse alignment during transport. The press moves via a conveyor line with press alignment functionality. Both converge at a camera detection point for image capture, and the coordinate data is transmitted to a high-speed transport robot for correction and grasping. Simultaneously, the lower channel performs tape production, including a tape feeding mechanism, a tape production mechanism, a tape pulling mechanism, and a curing conveyor mechanism. The high-speed robot in the upper channel moves in tandem with the press and pick-up of the battery cells. The lower channel repeats the same action, with the press and battery cells being handled by the robot in the upper channel. The adjacent battery cells are then welded alternately at the battery string assembly station on the curing conveyor line. The cells are then transported to the curing oven for conductive adhesive curing via the curing conveyor line. After curing, the cells flow into the string cutting mechanism, which cuts the continuous battery cells into 11 half-cell modules at the string spacing. The modules then flow into the EL inspection mechanism for dark box imaging and inspection. Finally, the robotic arm transports the modules to the discharge conveyor line for discharge. This system can meet the requirements of fast-paced production and high-efficiency production, with high welding efficiency and good operational stability.

[0024] 2) The adhesive-coated battery cell string welding machine of the present invention comprises:

[0025] ① Each welding wire has an independent working position and feeding process, with good traction and positioning accuracy and convenient maintenance;

[0026] ② The belt pulling and belt making mechanisms are assembled in one piece, ensuring alignment accuracy from the most fundamental part precision. All welding wire bending work is carried out simultaneously and the bending effect is uniform, avoiding hidden cracks at the gaps between cells when the cells are connected in series. The belt pulling adopts an uninterrupted alternating up and down method, resulting in a fast production cycle and good tension and holding capacity of the grippers.

[0027] ③ The press and the battery cells are transported synchronously. A camera is added at the material confluence point to ensure the integrity of the battery cells and prevent them from flowing into the next process. The camera also interacts with the robot signal, and the robot adaptively corrects its gripping, thereby improving the alignment accuracy of the welding wire and the glue application point of the battery cells.

[0028] ④ Add a pressure bonding mechanism to the curing conveyor to ensure that the welding wire is fully bonded to the grid of the battery cell and increase conductivity;

[0029] ⑤ To prevent positional accuracy deviations during battery string transportation, the conveyor belt is tensioned by a tensioning mechanism to ensure it remains taut and does not deviate during thermal deformation. Hot air circulation is used above the battery cells, and constant-temperature heating elements are used below to ensure uniform heating of the conductive adhesive during curing. The curing conveyor mechanism uses a high-flow-rate fan to maintain vacuum, ensuring the battery cells do not deviate during placement and transportation. A cooler and filter are installed before the vacuum fan to prevent high-temperature air and impurities from damaging the fan and affecting its lifespan. Furthermore, a pressure retrieval and alignment function is added to ensure centering accuracy when simultaneously gripping the battery cells. Attached Figure Description

[0089] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0090] Example:

[0091] The accompanying drawings illustrate a specific embodiment of the glue-applying battery cell string welding machine of the present invention. Figure 1 As shown, the string welding machine mainly includes a tape feeding mechanism 1, a tape making mechanism 2, a tape pulling mechanism 3, a glue pressing mechanism 4, a curing oven mechanism 5, a curing conveyor line mechanism 6, a battery cell loading and handling mechanism 7, a battery cell handling fork mechanism 8, a robot handling mechanism 9, a pressure tool conveying mechanism 10, a pressure tool recycling mechanism 11, a string cutting mechanism 12, and an EL detection mechanism 13.

[0092] Combination Figures 3 to 5 After the welding wire a of the feeding mechanism 1 is inserted into the feeding mechanism 2, it is clamped and fixed by the pulling mechanism 3. The feeding mechanism 2 performs bending and cutting actions and sends the welding wire a a certain distance. After the pulling mechanism 3 clamps and pulls out the required length of welding wire for two half pieces, the feeding mechanism 2 repeats the above actions to cut the welding wire a pulled out by the pulling mechanism 3, and at the same time prepares for the next pulling.

[0093] Specifically, the feeding mechanism 1 includes twenty-four wire coils 103 mounted on the feeding mounting plate 101 and driven by a stepper motor assembly 102. The wire coils 103 are inserted into the coil shaft 102a of the stepper motor assembly 102 and pressed and fixed by the clamping assembly 102b. In this embodiment, there are a total of 4 feeding mounting plates 101 and 24 stepper motor assemblies 102. By sliding and adjusting the position of the clamping assembly 102b on the coil shaft 102a, the unwinding position of the wire coils 103 can be adjusted (the inside of the wire coils 103 is pressed by springs). The unwinding is controlled by rotating the stepper motor assembly 102.

[0094] Welding wire a passes through guide wheel assembly 104, feed auxiliary wheel 105, and counterweight wheel 106, then enters welding wire guide anti-jump assembly 107 before being fed out. The counterweight wheel 106 is mounted on linear bearing assembly 109 via counterweight seat 108. One side of linear bearing assembly 109 is equipped with a low-position inductive detection switch 110 and an extreme position photoelectric switch 111 for detecting the counterweight wheel 106. When the counterweight wheel 106 is pulled up by the subsequent belt pulling mechanism 3, the low-position inductive detection switch 110 loses its signal, indicating insufficient welding wire length. Stepper motor assembly 102 begins unwinding. When a certain length is unwound, the counterweight wheel 106 returns to position L, the low-position inductive detection switch 110 receives a signal, stepper motor assembly 102 stops unwinding, and the extreme position photoelectric switch 111 provides detection and protection for the extreme position H of the counterweight wheel 106. The welding wire guide anti-jump assembly 107 mainly guides the welding wire through multiple guide posts. Each welding wire has an independent working position and feeding process, which has good traction and positioning accuracy and is easy to maintain.

[0095] Combination Figures 6 to 16 The tape-making mechanism 2 and the tape-pulling mechanism 3 are jointly mounted on the mounting plate 14 to ensure accuracy during the tape-pulling and tape-making processes. The tape-making mechanism 2 includes a tape-threading mechanism 201, a bending mechanism 202, a tape-feeding power mechanism 203, and a first cutting mechanism 204. The welding wire a passes through the tape-threading mechanism 201 into the bending mechanism 202. The tape-feeding power mechanism 203 is connected to the bending mechanism 202 to drive the bending mechanism 202 to move and send the cut end of the welding wire a certain distance out of the end of the first cutting mechanism 204. The tape-pulling mechanism 3 includes an inner tape-pulling handle 302 and an outer tape-pulling handle 303 respectively mounted on the linear motor moving module 301, and a tape-supporting mechanism 304. The inner and outer tape-pulling handles can pull the tape alternately up and down. After the pulled-out welding wire a is cut, the tape-supporting mechanism 304 supports the tail end of the welding wire.

[0096] Specifically, in combination Figure 7The threading mechanism 201 includes several first guide post groups 201b arranged on the threading base plate 201a. The welding wire a passes through two guide posts of the first guide post group 201b. A threading mounting plate 201d is rotatably mounted on the threading base plate 201a via a first rotating shaft 201c. The threading mounting plate 201d is equipped with 24 threading cylinders 201e, each of which drives one threading pressure post 201f to move up and down, pressing down to hold the welding wire a. The other end of the threading mounting plate 201d is connected and fixed to the threading base plate 201a via a first pin 201g. The threading mounting plate 201d is rotatable to facilitate threading.

[0097] Combination Figures 9 to 11 The bending mechanism 202 includes a base 202a, on which a guide plate 202b is mounted. Several second guide post groups 202c are arranged on one side of the guide plate 202b. The welding wire a passes through two guide posts of the second guide post group 202c. A bending block 202d is mounted on the guide plate 202b for bending the welding wire. A movable frame 202f is rotatably mounted on the base 202a via a second rotating shaft 202e. The other end of the movable frame 202f is connected and fixed to the base 202a via a second pin 202g. The movable frame 202f is rotatable for easy wire threading. A pressing cylinder 202h and a bending power cylinder 202i are respectively mounted on both sides of the movable frame 202f. The pressing cylinder 202h is connected to a pressing hammer 202j to press down and hold the welding wire a. The bending power cylinder 202i is connected to a bending hammer 202k to cooperate with the bending block 202d to perform the bending action. In practice, the pressure hammer 202j first presses down on the welding wire, and then the bending hammer 202k strikes downwards on the bending block 202d. The welding wire is struck downwards by the protruding part at the end of the bending hammer 202k, forming a Z-shaped deformation, thus achieving bending.

[0098] Combination Figure 8 The belt feeding power mechanism 203 includes a mounting assembly 203a connected to the bottom of the bending mechanism 202 and a first ball screw assembly 203b connected to drive the mounting assembly 203a. The belt feeding power mechanism 203 provides the bending mechanism 202 with a power to move back and forth.

[0099] Combination Figure 12 The first cutting mechanism 204 includes a cooperating upper cutting blade 204a and a lower cutting blade 204b. The lower cutting blade 204b is slidably mounted on a guide rail 204c and is driven to move up and down by a cutting blade cylinder 204d. The cutting blade cylinder 204d provides an upward tangential force, while the guide rails 204c on both sides provide vertical movement guidance. The lower cutting blade 204b is tightly fitted with the upper cutting blade 204a by the internal spring force, ensuring that there is no gap between the two cutting blades affecting the tangential force. The upper cutting blade 204a is mounted on a cutting blade holder, which is rotatably mounted at one end and fixed at the other end by a third pin. The cutting blade holder can rotate to facilitate threading.

[0100] Combination Figure 13 , Figure 14 The inner pull handle 302 and the outer pull handle 303 are respectively mounted on the lifting mechanism 305. The lifting mechanism 305 includes a second ball screw assembly 305b driven by a belt servo power assembly 305a. The inner and outer pull handles are mounted on a slider guide rail assembly 305c and are driven to rise and fall by the second ball screw assembly 305b. The lifting mechanism 305 is mainly used to realize the rising and falling action of the two pull handles.

[0101] Combination Figure 15 , Figure 16 The inner and outer pull handles each include a mounting body 306, a fixed clamping assembly 306a mounted on the mounting body 306, a movable clamping assembly 306b cooperating with the fixed clamping assembly 306a, a tension spring 306c located between the fixed clamping assembly 306a and the movable clamping assembly 306b, and a stop bolt 306d. The movable clamping assembly 306b is driven to move by a push cylinder 306e to achieve clamping. (Not shown) The push cylinder 306e is connected to a guide block with a guide ramp. When the push cylinder 306e extends, the movable clamping assembly 306b can move to the right as a whole under the guidance of the guide block to complete the clamping action. Each movable jaw 306f of the movable clamping assembly 306b is positioned and installed by a positioning post 306g and a compression spring 306h. Under the action of the compression spring 306h, each movable jaw 306f can adapt to the clamping environment and will not have uneven clamping force, thus avoiding situations where the welding wire is not clamped tightly or is easily dislodged.

[0102] The belt support mechanism 304 includes a belt support platform that is driven to rise and fall by a lifting cylinder, which can realize belt pulling and avoidance and belt lifting actions.

[0103] The coordinated operation of the belt feeding mechanism 2 and the belt pulling mechanism 3 is as follows: the belt threading mechanism 201, bending mechanism 202, and first cutting mechanism 204 are rotated and moved inwards, and the welding wire led out by the previous belt feeding mechanism 1 is sequentially threaded into and fixed on the inner belt pulling hand 302. Then, the belt threading mechanism 201, bending mechanism 202, and first cutting mechanism 204 are closed in sequence. The belt pulling operation begins. The bending mechanism 202 drives the end pressure hammer 202j through the pressure cylinder 202h to press the welding wire and fix it. The bending power cylinder 202i drives the end bending hammer 202k to bend the welding wire. The first cutting mechanism 204 cuts the welding wire. The belt feeding power mechanism 203 then drives the bending mechanism 202 forward by 10 mm, sending the cut end of the welding wire out 10 mm from the end of the first cutting mechanism 204, so that the next belt pulling mechanism 3 can pull out the welding wire. When the pulling mechanism 3 pulls the wire, the supporting mechanism 304 lowers to avoid it. After the welding wire is pulled out, the supporting mechanism 304 raises to support the tail of the welding wire. The inner pulling hand 302 and the outer pulling hand 303 pull the wire alternately. The welding wire is pulled out and cut in a direction away from the supporting mechanism 304 by the pulling hand. The tail end is supported by the supporting mechanism 304. After cutting the wire and completing the subsequent action, the pulling hand is raised to a certain height and returns to avoid it. At the same time, the other pulling hand lowers to a certain height to continue pulling and cutting the wire. Similarly, after completing the pulling action, it is raised and returns. The two pulling hands do not interfere with each other and form a "U" shaped movement path, alternating back and forth to pull the wire.

[0104] Combination Figure 2 , Figures 23 to 30 The battery cell loading and transporting mechanism 7 moves the battery cell b from station b1 of the battery cell transporting fork mechanism 8 to station b2. At the same time, the press conveying mechanism 10 transports the press c. The battery cell b and the press c are aligned and converge to the transport station j1 ​​of the robot transporting mechanism 9. The robot transporting mechanism 9 performs photo detection and aligns and grabs the battery cell b and the press c.

[0105] Specifically, the battery cell transport fork mechanism 8 includes a rear transport fork and a front transport fork. Both the input end of the rear transport fork and the output end of the front transport fork are equipped with a battery cell alignment mechanism 801. Both transport forks include a fixed fork 802 and a movable fork 803, the difference being the position of the battery cell alignment mechanism 801. To avoid further detail, the structure of the rear transport fork will be used as an example, combined with... Figure 26 , 27The movable fork 803 specifically includes a movable fork assembly 803a that is lifted and lowered by a fourth ball screw assembly 803b. The movable fork 803 is driven by a belt traverse assembly 804, which includes a belt 804a connecting the main and driven pulleys, a belt connecting plate 804b clamping the belt 804a, and a slider assembly 804c connected to the belt connecting plate 804b. The movable fork 803 is mounted on the slider assembly 804c. The four battery cells are initially located in the four rightmost positions of the movable fork assembly 803a. Each movement of the movable fork 803 moves the battery cells forward by two positions. After two lifting and forward movement operations, the four battery cells are transported to the four leftmost positions.

[0106] The battery cell loading and conveying mechanism 7 is set between two conveying forks for transferring battery cells b, combined with Figure 24 , Figure 25 The battery cell loading and conveying mechanism 7 includes a gripper assembly 702 mounted on the battery cell loading transverse module 701. The gripper assembly 702 includes a first suction cup 702b driven to rise and fall by a third ball screw assembly 702a, and a first vacuum generator 702c connected to the first suction cup 702b. The first suction cup 702b contacts the battery cell, the first vacuum generator 702c provides the vacuum required by the suction cup, the third ball screw assembly 702a provides the power for vertical movement, and the battery cell loading transverse module 701 provides the power for horizontal movement.

[0107] The press conveying mechanism 10 conveys the press c from the opposite direction, in conjunction with Figure 28 The press conveying mechanism 10 includes a press conveying line 1001. The output end of the press conveying line 1001 is equipped with a press alignment mechanism 1003 mounted on a press transverse module 1002. The press transverse module 1002 can drive the press alignment mechanism 1003 to move, thereby adjusting the distance between the press c and the battery cell b. Specifically, the press alignment mechanism 1003 includes an alignment frame 1003b with a position contact switch 1003a mounted at its front end. On both sides of the alignment frame 1003b are a press alignment cylinder 1003c and a side limit switch 1003d, respectively. After the press c is conveyed to contact the position contact switch 1003a, the press alignment cylinder 1003c extends, and the press c is pushed to contact the side limit switch 1003d, completing the alignment.

[0108] The robot handling mechanism 9 includes a camera detection mechanism 901, a robot 902, a clamping and battery cell gripper mechanism 903, and a second vacuum generator 904. After the camera detection mechanism 901 takes pictures of the battery cell b and the clamping device c, the robot 902 lowers the clamping and battery cell gripper mechanism 903 to a designated position to grip the battery cell b based on the photographic results. The second vacuum generator 904 provides suction force to the clamping and battery cell gripper mechanism 903 to pick up the battery cell b. In addition, after the camera detection mechanism 901 takes pictures and calculates, it can also precisely adjust the distance between the clamping device and the battery cell by moving the clamping device lateral movement module 1002 so that the robot 902 can grip it.

[0109] The camera photo detection mechanism 901 includes a camera 901a, a camera light source 901b that provides an auxiliary light source for the camera 901a to take pictures, and a backlight 901c.

[0110] The structural combination of the clamp and the battery cell gripper mechanism 903 Figure 29 As shown, it mainly includes a suction cup base 903a. One end of the suction cup base 903a is equipped with a second suction cup 903b for picking up the battery cell b, and the other end is elastically mounted with an electromagnet 903d for adsorbing the pressure fixture c via a lifting seat 903c. The lifting seat 903c is also connected to a proximity switch 903e for detecting whether the pressure fixture c is adsorbed in place. When the robot 902 moves the pressure fixture and battery cell gripper mechanism 903 downward, the second suction cup 903b picks up the battery cell b, the second vacuum generator 904 provides a vacuum to the second suction cup 903b, the electromagnet 903d presses down on the adsorbing pressure fixture c, and at the same time the lifting seat 903c moves upward. When the proximity switch 903e receives a signal, the robot 902 stops moving downward, completing the simultaneous gripping of the battery cell b and the pressure fixture c. Figure 30 As shown.

[0111] The overall operation of the battery cell loading and transport mechanism 7, the battery cell transport fork mechanism 8, the robot transport mechanism 9, and the fixture conveying mechanism 10 is as follows: Four battery cells, after being coated with adhesive, are first transported by the rear transport fork to the loading position of the battery cell loading and transport mechanism 7. The battery cell loading and transport mechanism 7 then transports the battery cells to the front transport fork, which repeats the reciprocating transport motion until the battery cells are transported to the camera detection position of the camera detection mechanism 901. The synchronous fixture is aligned and conveyed into place by the fixture conveying mechanism 10. The camera 901a begins taking pictures. The camera light source 901b and backlight 901c are constantly on to provide auxiliary lighting for the camera 901a. After taking pictures, the XY axis coordinate data of the battery cells are transmitted to the robot program, enabling linkage with the robot 902. The robot 902 aligns, corrects deviations, and grasps the fixture synchronously.

[0112] The pulling mechanism 3 pulls the welding wire a to the welding wire battery cell assembly station a1 of the curing conveyor mechanism 6 to perform a straightening and tightening action. Then, the robot handling mechanism 9 aligns the pressure fixture c and the battery cell b on the welding wire a. The first pressure fixture c presses down on the front section of the welding wire a, and the subsequent battery cell b presses down on the rear section of the welding wire a. This process is repeated, and the battery cell and pressure fixture flow to the handling station j1. The robot handling mechanism 9 takes a picture for inspection, grabs and waits, and the feeding, making, and pulling mechanisms produce two half-lengths of welding wire, pulling them above the first battery cell placement position. At this time, the pressure fixture and battery cell are aligned again, with the pressure fixture pressing down on the welding wire above the first battery cell, and the subsequent battery cell pressing down on the rear section of the welding wire. This process is repeated to create a continuous battery string assembly, such as... Figure 38 As shown.

[0113] Combination Figures 17 to 22 The pressure bonding mechanism 4 is located at one end of the curing conveyor mechanism 6, and the curing oven mechanism 5 is located above the curing conveyor mechanism 6. The battery string assembly flows forward through the curing conveyor mechanism 6. Before entering the curing oven mechanism 5, the pressure bonding mechanism 4 presses down on the pressure fixture c to discharge the adhesive. After curing in the curing oven mechanism 5, the battery string flows out, and the pressure fixture c is transported by the pressure fixture recycling mechanism 11 to the pressure fixture conveyor mechanism 10 for reuse.

[0114] Specifically, in combination Figure 18 The adhesive pressing mechanism 4 includes a lifting plate 402 driven to rise and fall by an adhesive pressing cylinder 401, a pushing cylinder 403 mounted on the lifting plate 402, a pushing frame 404 connected to the pushing cylinder 403, and a plurality of adhesive pressing needles 405 elastically mounted on the pushing frame 404. The adhesive pressing needles 405 can apply a downward pressure to the top of the pressing tool. This pressure is transmitted to the welding wire to press out the conductive adhesive between the welding wire and the grid of the battery cell for full adhesion. The pushing cylinder 403 can adjust the position of pressing the pressing tool.

[0115] Combination Figure 17 , Figure 19 The curing conveyor mechanism 6 includes a conveyor power mechanism 601, a conveyor belt 602, a tensioning mechanism 603, a tail clamp mechanism 604, a vacuum cooling and filtration system 605, and a vacuum pipe 606. A thermocouple is installed below the conveyor belt 602 to heat the battery strings. The conveyor power mechanism 601 drives the conveyor belt 602 to feed the battery cells into the curing oven mechanism 5 step by step at intervals between the cells. The tensioning mechanism 603 is used to adjust the tension or relaxation of the conveyor belt 602. The tensioning mechanism 603 includes a tensioning wheel 603b driven by a double cylinder 603a, which tensions the conveyor belt 602.

[0116] Tail clamp mechanism 604 is installed on one side of conveyor belt 602 to cooperate with belt pulling mechanism 3 to straighten welding wire a. The structure of tail clamp mechanism 604 is as follows: Figure 21As shown, it mainly includes a lifting plate 604b driven by a lifting cylinder 604a, a fixed claw 604c disposed on the lifting plate 604b, and a sliding plate 604e driven by a clamping cylinder 604d mounted on the lifting plate 604b. The sliding plate 604e is provided with a movable claw 604f that cooperates with the fixed claw 604c. The tail clamp mechanism 604 can descend to avoid the pulling action of the pulling mechanism 3, and can also rise to straighten the welding wire a in cooperation with the pulling mechanism 3.

[0117] The vacuum cooling and filtration system 605 provides adsorption force to the surface of the conveyor belt 602 and cools the inhaled hot air through the vacuum pipe 606. Specifically, the vacuum cooling and filtration system 605 includes a vacuum fan 605a, a filter 605b, and a cooler 605c connected in sequence. The cooler 605c is connected to the vacuum pipe 606. The vacuum cooling and filtration system 605 not only assists in fixing the battery cells, but also, because the internal temperature of the curing conveyor mechanism 6 and the curing oven mechanism 5 is too high, if the vacuum fan 605a inhales excessively hot air, it will reduce its lifespan. Therefore, a cooler 605c is added before the fan to prevent damage to the fan.

[0118] Combination Figure 19 , Figure 22 The curing oven mechanism 5 includes a heating oven 501, a hot air circulation mechanism 502, and a pull rod mechanism 503. As the battery cells and molds enter the heating oven 501 and exit, the welding wire of the entire string of batteries is cured at the glued area of ​​the battery cell grid. To ensure the curing effect, the hot air circulation mechanism 502 is connected to the heating oven 501 to circulate hot air to blow onto the surface of the battery string assembly. The hot air circulation mechanism 502 includes an air inlet box 502a, a circulating fan 502b, and an air outlet box 502c connected in sequence. The air outlet box 502c is connected to the bend pipe 501a of the heating oven 501, and the top pipe 501b of the heating oven 501 is connected to the air inlet box 502a. When the circulating fan 502b draws in hot air, it passes through a long pipe, naturally reducing the temperature during blowing. Therefore, a heating element 502d is also provided in the air inlet box 502a to heat the hot air that has lost temperature due to the long pipe, ensuring the auxiliary curing temperature during blowing. The tie rod mechanism 503 is connected to the heating furnace 501, which can flip the heating furnace 501 to one side for easy maintenance.

[0119] Furthermore, in combination Figure 31 The pressure vessel recycling mechanism 11 includes a Z-axis lifting module 1102 mounted on the recycling transverse module 1101 and a forward / backward moving module 1103 connected to the Z-axis lifting module 1102. The forward / backward moving module 1103 is equipped with an electromagnet adsorption assembly 1104 for adsorbing the pressure vessel c. The electromagnet adsorption assembly 1104 has three pairs and can simultaneously pick up three sets of pressure vessels c. The stopping action of the Z-axis lifting module 1102 moving downward to pick up the pressure vessel is consistent with the downward movement of the pressure vessel and the battery cell gripper mechanism 903 to pick up the pressure vessel.

[0120] Combination Figure 20 This is the assembly station for connecting the battery cells and welding wire in series, and the placement position for the welding wire after the inner and outer pull straps are bent, as well as the placement position for the clamps and battery cells transported by the robot handling mechanism 9. When the pull strap mechanism 3 pulls the welding wire a to this station, the length of the pulled welding wire is two and a half pieces of welding wire length L. The tail clamp mechanism 604 first moves to a low position to avoid the pull strap action, and then uses the lifting cylinder 604a to lift the clamping jaws. After the welding wire a falls into the opened tail clamp mechanism 604, the clamping cylinder 604d extends, the clamping jaws close, clamp the welding wire and tighten it, so that the robot handling mechanism 9 can align and attach the glued part of the battery cell to the welding wire.

[0121] Combination Figures 32 to 37 The cured battery string flows into the string cutting mechanism 12, which cuts the battery string at the string spacing to form the finished battery string. Then, the battery string is powered on and photographed by the EL detection mechanism 13 to detect the current flow of the battery string. OK products flow out of the conveyor line, and NG products are placed in the waste chip position.

[0122] Specifically, in combination Figure 33 , Figure 34 The string cutting mechanism 12 includes a timing belt assembly 1201, a second cutting mechanism 1202, a first through-beam photoelectric group 1203, a second through-beam photoelectric group 1204, and a lead screw power assembly 1205. The battery string is conveyed by the timing belt assembly 1201. The first through-beam photoelectric group 1203 and the second through-beam photoelectric group 1204 are respectively connected to both sides of the second cutting mechanism 1202. The first through-beam photoelectric group 1203 is used to count the number of battery cells, and the second through-beam photoelectric group 1204 is used to detect the cutting position. The lead screw power assembly 1205 is connected to the second cutting mechanism 1202 to compensate for the conveying error of the timing belt assembly 1201.

[0123] The EL testing mechanism 13 includes a feeding conveyor line 1301, a cylinder gripping and rotating mechanism 1302, a module gripping and rotating mechanism 1303, a power-on gripper mechanism 1304, and a finished product transverse transfer module 1305. The feeding conveyor line 1301 conveys the cut battery strings forward to their designated positions. The cylinder gripping and rotating mechanism 1302 picks up the battery strings and rotates them to a higher position. The module gripping and rotating mechanism 1303, mounted on the finished product transverse transfer module 1305, moves to above the battery strings, picking them up from the cylinder gripping and rotating mechanism 1302 and rotating them 90° for manual inspection. The power-on gripper mechanism 1304, mounted on the module gripping and rotating mechanism 1303, closes the exposed welding wires on both sides of the battery string after manual inspection, and then powers on the battery string to test its quality.

[0124] The feeding conveyor line 1301 is equipped with a position detection switch 1301a, which is used to detect whether the battery string has been conveyed to the correct position.

[0125] Structural integration of cylinder gripping and rotating mechanism 1302 Figure 35 As shown, it mainly includes a rotating beam 1302a with a first suction cup assembly 1302b and a sensor switch 1302c arranged thereon. The two ends of the rotating beam 1302a are respectively mounted on a lifting guide 1302f via a bearing assembly 1302d and a first rotating cylinder 1302e. The lifting guide 1302f is mounted on a lifting guide rail 1302g and is driven to move up and down by a first pen cylinder 1302h. The first rotating cylinder 1302e provides 180° rotational power.

[0126] Structural integration of module gripping and rotating mechanism 1303 Figure 36 As shown, it mainly includes a support beam assembly 1303b mounted on the Z-axis module 1303a, and a semi-rotating assembly 1303d mounted on the support beam assembly 1303b and driven to rotate by a second rotary cylinder 1303c. The semi-rotating assembly 1303d is provided with several second suction cup assemblies 1303e. The second rotary cylinder 1303c provides 90° rotational power.

[0127] The power-on gripper mechanism 1304 is fixedly mounted on the semi-rotating assembly 1303d, and the structure of the power-on gripper mechanism 1304 is combined with... Figure 37 As shown, it mainly includes a moving electrode claw 1304c driven by a second pen cylinder 1304a to rotate around a third rotating axis 1304b, and a fixed electrode claw 1304d that cooperates with the moving electrode claw 1304c to close and be energized. The moment the energized gripper mechanism 1304 is activated, an image is taken through the EL detection dark box below. Figure 1 (g1 is a reserved station for EL detection dark box) to detect whether the current of the battery string is flowing. On one side of the feeding conveyor line 1301, there is a discharging conveyor line 1306 and a waste line 1307. OK products are discharged through the discharging conveyor line 1306, and NG products are transported to the waste line 1307.

[0128] The overall operation of the string cutting mechanism 12 and the EL detection mechanism 13 is as follows: when the battery string comes out of the curing conveyor line mechanism 6, it is first conveyed forward by the synchronous belt assembly 1201 of the string cutting mechanism 12. When it passes the first photoelectric group 1203, it will count 11 half-cells. When it irradiates the head of the eleventh cell, the battery string stops transporting. Then, the second cutting mechanism 1202 is compensated by the bottom lead screw power assembly 1205 to transport a small distance. The second cutting mechanism 1202 is aligned with the center of the string spacing to punch. The second photoelectric group 1204 is used to precisely control the punching position to prevent the cell from being cut.

[0129] After the cutting is completed, the battery string moves forward through the feeding conveyor line 1301 of the EL detection mechanism 13. When the battery string reaches the position of the position detection switch 1301a, the transport stops. At this time, the cylinder gripping and rotating mechanism 1302 moves downward. When the first suction cup assembly 1302b contacts the battery string, the induction switch 1302c senses the battery string, the first rotating cylinder 1302e rotates, and the first pen cylinder 1302h pulls up, rotating the battery string to the upper position.

[0130] Next, the finished product transverse module 1305 drives the module gripping and rotating mechanism 1303 to move to the battery string. The module gripping and rotating mechanism 1303 moves downward a certain distance to pick up the battery string from the cylinder gripping and rotating mechanism 1302 and rotates it 90° for manual visual inspection. If the inspection is qualified, the two-sided power-on gripper mechanism 1304 closes and clamps the exposed welding wires on both sides of the battery string, energizing the battery string. At the moment of power-on, the EL detection dark box below will take a picture to check whether the current flows through the battery string. If it is qualified, it will be discharged from the discharge conveyor line 1306; if it is unqualified, it will be transported to the waste line 1307.

[0131] Battery string assemblies manufactured by the string welding machine of this invention, such as Figure 38 As shown, in actual production, depending on different working conditions, the spot pressure type fixture c (used by conventional welding machines) can be selected. Figure 38 Alternatively, a strip press can be used, with the strip press performing better in the curing process. The only difference between the two is that one uses a press needle c1 (such as...). Figure 41 Another method uses a pressure strip. When the pressure fixture c presses down on the welding wire a, it can press out the conductive adhesive e between the welding wire a and the cell grid line d to ensure a full fit, such as... Figure 42 As shown.

[0132] This invention features a linear layout and a U-shaped flow of the press, with two channels for process implementation. The upper channel is for the convergence of the press and the battery cells, while the right half of the lower channel is for welding wire fabrication, and the left half is for assembling and curing the battery cells and welding wire into strings. The battery cells are transported using a forklift, with two sets of alignment structures for coarse alignment during transport. The press moves via a conveyor line, which also has a press alignment function. Both converge at a camera detection point for image capture, and the coordinate data is transmitted to a high-speed transport robot for correction and grasping. Simultaneously, the lower channel performs tape production, which includes a tape feeding mechanism, a tape production mechanism, a tape pulling mechanism, a curing conveyor mechanism, and the upper... The high-speed robot in the channel moves in a coordinated manner, with the robot repeatedly pressing and placing the battery cells. The lower channel repeats the pressing and battery cell handling actions of the robot in the upper channel. The adjacent battery cells are staggered and welded at the battery string assembly station of the curing conveyor line. The cells are transported to the curing oven for conductive adhesive curing via the curing conveyor line. After curing, the cells flow into the string cutting mechanism, which cuts the continuous battery cells into 11 half-cell modules at the string spacing. The modules then flow into the EL inspection mechanism for dark box imaging and inspection. Finally, the robotic arm transports the modules to the discharge conveyor line for discharge. This system can meet the requirements of fast-paced production and high-efficiency production, with high welding efficiency and good operational stability.
