The EPE strip laying machine 20, the bus bar laying machine 10, and the bus bar welding machine 30 are connected by a battery string conveying line 40. The battery string is sequentially conveyed to the EPE strip laying machine 20, the bus bar laying machine 10, and the bus bar welding machine 30 through the battery string conveying line 40.

[0056] The battery string is sequentially conveyed to the EPE strip laying machine 20, the bus bar laying machine 10, and the bus bar welding machine 30 through the battery string conveying line 40. The EPE strip laying machine 20 lays the EPE strip on the battery string. The bus bar is laid through the bus bar conveyor. The bus bar is welded to the lead of the battery string through the bus bar welding machine 30. The embodiment of the present application can automatically realize the laying, laying, and welding of the EPE strip, with high automation, saving labor costs and improving work efficiency. Among them, the battery string conveying line 40 is an ordinary conveying line used by existing intelligent devices. The battery string conveying line 40 can be a conveyor belt, and the conveyor belt is driven by a motor to run. In one embodiment, the battery string conveying line 40 can be composed of multiple sections of conveying lines connected in series. The battery string is conveyed through multiple sections of conveying lines in the entire production line. Each section of the conveying line can be composed of multiple conveyor belts connected in series.

[0057] In one embodiment, multiple conveying lines can be in a "mouth" - shaped structure, and the adjacent conveying lines at the turning point are perpendicular or approximately perpendicular to each other. In order to realize the conveying of the battery string between the adjacent conveying lines, a turning platform device 50 is provided between the adjacent conveying lines. The turning platform device 50 is connected to two adjacent sections of conveying lines. The two adjacent sections of conveying lines are in an L - shaped structure. The turning platform device 50 is used for the battery string to turn and be conveyed between the two sections of conveying lines.

[0058] As shown in Figure 2 , Figure 3 Figure, specifically, the turntable device 50 includes a first turning and conveying mechanism 51, a second turning and conveying mechanism 52, and a turning connection mechanism 53. The conveying direction of the first turning and conveying mechanism 51 is opposite to that of the second turning and conveying mechanism 52, and the conveying directions of the first turning and conveying mechanism 51 and the second turning and conveying mechanism 52 are perpendicular or approximately perpendicular to the conveying direction of the turning connection mechanism 53. The battery string conveyed onto the first turning and conveying mechanism 51 is conveyed onto the second turning and conveying mechanism 52 through the turning connection mechanism 53.

[0059] Among them, both the first turning and conveying mechanism 51 and the second turning and conveying mechanism 52 are composed of three sections of conveyor belts, and each section of conveyor belt is composed of two conveyor belts. Each conveyor belt can be driven by a motor to rotate, so as to realize the conveying of the battery string. There is a gap between adjacent conveyor belts, and both ends of the turning connection mechanism 53 are located in the gaps between the first turning and conveying mechanism 51 and the second turning and conveying mechanism 52.

[0060] The turning connection mechanism 53 includes a turning connection conveyor line 530, a turning connection lifting component 531, and a connection conveyor support component 532. The turning connection conveyor line 530 includes four sections of conveyor belt components, and each section of conveyor belt is composed of three conveyor belts. The conveyor belt can be driven by a motor to run. There is a gap between each section of conveyor belt, that is, the three sections of conveyor belts can be started and run simultaneously, and each section of conveyor belt can also be started and run independently, so as to facilitate the stacking of the battery string on the conveyor belt.

[0061] The turning connection lifting component 531 is connected to the turning connection conveyor line 530 and the connection conveyor support component 532, and the turning connection lifting component 531 drives the turning connection conveyor line 530 and the connection conveyor support component 532 to lift and lower. Specifically, the turning connection lifting component 531 includes a chassis 5311 and a lifting frame 5311. A cylinder 5312, a chain, and an eccentric wheel 5313 are arranged on the chassis 5311. The cylinder 5312 is fixed to the chassis 5311 by bolts or the like, and the eccentric wheel 5313 is rotatably connected to the chassis 5311 through a transmission shaft. The chain is engaged with the eccentric wheel 5313, and the piston rod of the cylinder 5312 is connected to the chain. The cylinder 5312 drives the chain to move reciprocally, so as to realize the reciprocating rotation of the eccentric wheel 5313. The bottom of the lifting frame 5311 abuts against the eccentric wheel 5313, and the lifting frame 5311 is driven to rise or fall during the rotation of the eccentric wheel 5313. The turning connection conveyor line 530 and the connection conveyor support component 532 are both arranged on the lifting frame 5311.

[0062] After the battery string is conveyed to the first turning conveying mechanism 51, the lifting frame 5311 rises, driving the turning connection conveying line 530 and the connection conveying support assembly 532, so as to transfer the battery string on the first turning conveying mechanism 51 to the turning connection conveying line 530. Then, the turning connection conveying line 530 drives the battery string to convey in the direction of the second turning conveying mechanism 52. After the battery string is located above the second turning conveying mechanism 52, the lifting frame 5311 descends, so as to transfer the battery string to the second turning conveying mechanism 52, realizing the turning conveyance of the battery string.

[0063] The connection conveying support assembly 532 includes a plurality of support wheels 5320, which are located between the conveyor belts of the turning connection conveying line 530 to support the battery string, so as to better realize the stable conveyance of the battery string.

[0064] In an embodiment, in order to protect the battery string, a blocking frame 54 or a blocking plate may be provided at the ends of the first turning conveying mechanism 51 and the turning connection conveying line 530, so as to prevent the battery string from colliding and running out during the conveying process.

[0065] As Figures 4 to 9 shown, in an embodiment, the EPE strip feeding device includes a short EPE strip feeding mechanism 210 and a long EPE strip feeding mechanism 211. Among them, the short EPE strip feeding mechanism 210 is used to feed two short EPE strips, and the long EPE strip feeding mechanism 211 is used to feed one long EPE strip.

[0066] In order to realize the feeding of the short EPE strip, the short EPE strip feeding mechanism 210 includes a short EPE strip coil 2101, a short EPE strip traction assembly 2102, a short EPE strip turning assembly 2103 and a short EPE strip cutting assembly 2104. The short EPE strip traction assembly 2102 is used to clamp one end of the EPE strip, and the short EPE strip cutting assembly 2104 is used to cut the short EPE strip. The cut short EPE strip is turned by the short EPE strip turning assembly 2103.

[0067] Among them, the coiled EPE strip is placed on the short EPE strip coil 2101, and the short EPE strip coil 2101 is placed on the short EPE strip feeding base 2105. And the short EPE strip coil 2101 can be rotationally connected to the short EPE strip feeding base 2105 through a transmission shaft or the like. In order to guide the EPE strip, a plurality of guide shafts are provided on the short EPE strip feeding base 2105, and the EPE strip is guided by the plurality of guide shafts. In an embodiment, the short EPE strip coil 2101 can also be driven by a motor or the like.

[0068] The short EPE strip traction assembly 2102 is arranged at the front end of the short EPE strip coil 2101. The guiding shaft is placed between the short EPE strip coil 2101 and the short EPE strip traction assembly 2102. The short EPE strip cutting assembly 2104 is placed between the short EPE strip traction assembly 2102 and the guiding shaft. To realize the traction of the EPE strip, the short EPE strip traction assembly 2102 includes a short EPE strip traction cylinder 21021 and a traction jaw 21022. The short EPE strip traction cylinder 21021 is connected to the traction jaw 21022, and the short EPE strip traction cylinder 21021 drives the traction jaw 21022 to move in the direction close to or away from the short EPE strip cutting assembly 2104. The opening and closing of the traction jaw 21022 can be controlled by a thumb cylinder. After the traction jaw 21022 clamps one end of the EPE strip, it can drive the EPE strip to move, so as to pull out a certain length of the EPE strip, and then the short EPE strip cutting assembly 2104 cuts off the EPE strip.

[0069] To realize the cutting of the EPE strip, the short EPE strip cutting assembly 2104 includes a short EPE strip cutting cylinder 21041 and an EPE strip cutter. The short EPE strip cutting cylinder 21041 is connected to the EPE strip cutter and drives it to move up and down, so as to cut off the EPE strip located below the EPE strip cutter. Among them, the cutter is an existing cutter used in the equipment for producing solar cell wafers.

[0070] The short EPE strip loading mechanism 210 further includes a fixing assembly 2106. The fixing assembly 2106 is located between the short EPE strip cutting assembly 2104 and the guiding shaft. The fixing assembly 2106 includes a fixing driving cylinder 21061 and a fixing pressing plate 20162. The fixing driving cylinder 21061 is connected to the fixing pressing plate 20162, and the fixing driving cylinder 21061 drives the fixing pressing plate 20162 to move up and down. Before the short EPE strip traction assembly 2102 traction the EPE strip, first, the fixing driving cylinder 21061 drives the fixing pressing plate 20162 to move downward, and the fixing pressing plate 20162 presses and fixes the EPE strip close to the guiding shaft. Then, the short EPE strip traction assembly 2102 traction the EPE strip.

[0071] The short EPE strip feeding mechanism 210 further includes a cutting and moving component 2107, which is connected to the short EPE strip cutting component 2104, and the cutting and moving component 2107 can drive the short EPE strip cutting component 2104 to move. Preferably, the cutting and moving component 2107 drives the short EPE strip cutting component 2104 to move in a direction closer to or away from the short EPE strip traction component 2102. After one end of the EPE strip is fixed by the fixing component 2106, the cutting and moving component 2107 drives the short EPE strip cutting component 2104 to move away from the short EPE strip traction component 2102, so that the other end of the EPE strip is exposed, and then the short EPE strip traction component 2102 clamps the EPE strip. Then, the fixing driving cylinder 21061 of the fixing component 2106 drives the fixing pressing plate 20162 to move upward, and the short EPE strip traction component 2102 pulls the EPE strip to move to the strip pulling position. Then, the cutting and moving component 2107 drives the short EPE strip cutting component 2104 to move a predetermined distance in a direction closer to the short EPE strip traction component 2102, and the short EPE strip cutting component 2104 cuts the EPE strip.

[0072] Specifically, the cutting and moving component 2107 includes a cutting and moving cylinder 21071 and a cutting and moving slide rail 21072. The short EPE strip cutting component 2104 is connected to the cutting and moving slide rail 21072 through a slider. The cutting and moving cylinder 21071 is connected to the short EPE strip cutting component 2104, and the cutting and moving cylinder 21071 drives the short EPE strip cutting component 2104 to move along the cutting and moving slide rail 21072.

[0073] In one embodiment, the short EPE strip feeding mechanism 210 further includes an EPE strip supporting component 2108. The EPE strip supporting component 2108 is connected to the short EPE strip traction component 2102 and is used to support the cut EPE strip onto the short EPE strip turning component 2103. The short EPE strip turning component 2103 can drive the short EPE strip to rotate by 90 degrees, thereby realizing the angle adjustment of the short EPE strip. The EPE strip supporting component 2108 can be a conveyor belt, and the EPE strip supporting component 2108 is connected to the short EPE strip traction component 2102 through a connecting plate. After the short EPE strip is cut, the EPE strip supporting component 2108 drives the short EPE strip traction component 2102 to move towards the short EPE strip turning component 2103 until the short EPE strip is transferred above the short EPE strip turning component 2103. Then the traction jaws 21022 open, and the short EPE strip is placed on the short EPE strip turning component 2103. The short EPE strip turning component 2103 includes a turning support plate 21081, and the turning support plate 21081 can be driven to rotate by an existing rotary cylinder. It should be noted that in this embodiment, there are two turning support plates 21081 to realize the feeding of two short EPE strips at a time. Among them, the two turning support plates 21081 can be arranged side by side, and the EPE strip supporting component 2108 supports the two short EPE strips into the turning support plates 21081.

[0074] In another embodiment, the short EPE strip feeding mechanism 210 may further include a support plate moving component 2109. The support plate moving component 2109 is connected to the turning support plate 21081. After the short EPE strip is placed on the turning support plate 21081, the support plate moving component 2109 drives the turning support plate 21081 to move away from the EPE strip supporting component 2108, so as to facilitate the subsequent picking of the short EPE strip. The support plate moving component 2109 can be conveyed by a motor and a conveyor belt.

[0075] In one embodiment, the long EPE strip feeding mechanism 211 is used for feeding long EPE strips. The long EPE strip feeding mechanism 211 includes a long EPE strip feeding tray 2111, a stock preparation tray 2110, and a long EPE strip supporting plate. Both the long EPE strip feeding tray and the stock preparation tray 2110 are provided with a large tray and a small tray. The long EPE strip supporting plate is provided with a first feeding channel 2112 and a second feeding channel 2113. Pulling claws 2114 are arranged on the sides of both the first feeding channel 2112 and the second feeding channel 2113. It should be noted that the long EPE strip feeding tray 2111 and the stock preparation tray 2110 are relatively named, that is, one group is used for feeding and the other group is used for stock preparation. Both the long EPE strip feeding tray 2111 and the stock preparation tray 2110 include two trays, namely a large tray and a small tray, and can achieve feeding one strip at a time or two strips at a time as needed. The feeding is all onto the first feeding channel 2112 or the second feeding channel 2113. There are claws on both the left and right sides of the pulling claws 2114 to meet the feeding requirements at both the left and right ends respectively. The EPE strip feeding tray and the stock preparation tray 2110 are symmetrically arranged left and right.

[0076] Limit blocks 2115 and limit posts 2116 are arranged in both the first feeding channel 2112 and the second feeding channel 2113. The limit block 2115 is connected to the limit cylinder through an adjustment plate 2117. The limit cylinder and the adjustment plate 2117 drive the limit block 2115 to move, and the position of the long EPE strip on the first feeding channel 2112 or the second feeding channel 2113 can be adjusted in cooperation with the limit post 2116. That is, the limit cylinder drives the limit block 2115 to move towards the direction close to the limit post 2116, so that the long EPE strip is placed between the limit block 2115 and the limit post 2116.

[0077] Among them, the long EPE strip feeding mechanism 211 also includes a short EPE strip cutting assembly 2104, a fixing assembly 2106, and a cutting moving assembly 2107, and the structure of the pulling claws 2114 is similar to that of the short EPE strip traction assembly 2102. The principle of the long EPE strip feeding mechanism 211 to realize feeding and cutting is similar to that of the short EPE strip feeding mechanism 210. Different from the short EPE strip feeding mechanism 210, the long EPE strip feeding mechanism 211 directly pulls the EPE strip onto the first feeding channel 2112 and the second feeding channel 2113 through the pulling claws 2114.

[0078] In one embodiment, the first tape feeding device 22 can be an existing tape peeling machine, and this tape peeling machine can realize the feeding, peeling, and cutting of the tape.

[0079] The EPE strip laying manipulator 23 includes a six-axis robot 230 and a suction rod module 231. The suction rod module 231 is connected to the six-axis robot 230. The suction rod module 231 includes a long EPE strip suction cup group, a short EPE suction cup group, and a tape suction cup group. During operation, the six-axis robot 230 can flexibly turn and displace in six degrees of freedom. The long EPE strip suction cup group on the suction rod module 231 is used to adsorb the long EPE strip in the X-axis direction, the short EPE suction cup group is used to adsorb two short EPE strips in the Y-axis direction on the steering carrier plate 21081, and the tape suction cup group is used to adsorb two pieces of tape. The suction rod module 231 realizes the feeding of the tape and the EPE strip through vacuum adsorption. The working principle and structure of the six-axis robot 230 can both be prior art.

[0080] The working steps of the EPE strip laying machine 20 are as follows: First, the six-axis robot 230 drives the short EPE suction cup group on the suction rod module 231 to sequentially adsorb two short EPE strips on the steering carrier plate 21081. Then, the six-axis robot 230 drives the moving suction rod module 231 under the long EPE strip and uses the long EPE strip suction cup to pick up the long EPE strip. Then, the six-axis robot 230 and the suction rod module 231 rotate and swing above the tape feeding mechanism to pick up two pieces of tape. Finally, the six-axis robot 230 and the suction rod module 231 rotate and swing to the battery string at the battery string conveyor line 40, place the long EPE strip and two short EPE strips in sequence, and place the two pieces of tape at the joints between the two short EPE strips and the long EPE strip in sequence to complete the laying.

[0081] After the long EPE strip and the short EPE strip in this embodiment are laid, they form an "F" - shaped structure, and the tape is laid at the joint between the long EPE strip and the short EPE strip, so that the long EPE strip and the short EPE strip are connected together.

[0082] In the automated battery string production line of the present application, the battery string is first conveyed by the battery string conveyor line 40 to the EPE strip laying machine 20 for laying the EPE strip, and then is conveyed by the battery string conveyor line 40 to the bus bar laying machine 10 for laying the bus bar.

[0083] Such as Figures 10 to 18The busbar loading and bending device 11 includes an L-shaped loading and bending module 111, and the L-shaped loading and bending module 111 includes a first busbar loading mechanism 1111, a first busbar pulling mechanism 1112, a first busbar cutting mechanism 1113 and a first busbar bending mechanism 1114. The first busbar pulling mechanism 1112 and the first busbar cutting mechanism 1113 are located on one side of the first busbar loading mechanism 1111. The first busbar pulling mechanism 1112 is used to pull out a busbar of a predetermined length. The busbar is cut by the first busbar cutting mechanism 1113, and the cut busbar is bent into an L shape by the first busbar bending mechanism 1114. The busbar laying manipulator 13 includes a laying six-axis robot 130 and a busbar suction cup assembly. The busbar suction cup assemblies are all connected to the laying six-axis robot 130. The L-shaped busbar is sucked by the busbar suction cup assembly and placed at a predetermined position on the battery string.

[0084] The busbar is loaded through the first busbar loading mechanism 1111, then a busbar of a predetermined length is pulled out by the first busbar pulling mechanism 1112, and then the busbar is cut off by the first busbar cutting mechanism 1113. Finally, the cut busbar is bent into an L shape by the first busbar bending mechanism 1114. The bent busbar is sucked by the busbar laying manipulator 13 and placed at a predetermined position on the battery string.

[0097] Specifically, the structure and working principle of the second bus bar loading mechanism 1120 are the same as those of the first bus bar loading mechanism 1111. For its structure and working principle, reference can be made to the above-mentioned first bus bar loading mechanism 1111, and details will not be elaborated here.

Details will not be elaborated here. The two second bending assemblies 11232 cooperate together to bend the long strip-shaped bus bar into a U shape.

[0100] In the long U-shaped loading and bending module 112, the two second pressing strip assemblies 11231 can be driven by an existing linear module to move in the horizontal and vertical directions, so as to adjust their positions.

[0101] In one embodiment, the second busbar bending mechanism 1123 further includes a second bending movement component 1126.

[0104] The structure and working principle of the short U-shaped loading and bending module 113 are the same as those of the long U-shaped loading and bending module 112, and will not be described in detail here. Since the size of the U-shaped busbar bent by the long U-shaped loading and bending module 112 is larger than the size of the U-shaped busbar bent by the short U-shaped loading and bending module 113, the short U-shaped loading and bending module 113 has a smaller volume and a more compact structure.

The clamping driving member 12040 drives the tape clamping jaw 12041 to move towards or away from one end of the tape

[0111] After the tape is fed, the folding jaws 12031 are initially in an open / closed state. The tape passes through the middle of the folding jaws 12031 and is clamped by the folding jaws 12031. Then, the folding rotary cylinder 12032 drives the folding jaws 12031 to rotate 180 degrees, so that the adhesive sides of the tape on both sides of the folding jaws 12031 adhere to each other, forming a non-adhesive folding surface on the tape. After the tape is folded, the tape clamping jaw 12041 clamps the folded position of the tape, and while clamping the tape, the folded position is also compacted. Then, the folding moving assembly 12030 drives the folding jaws 12031 to move away from the tape, so that the folding jaws 12031 are withdrawn from the tape. Then, the second clamping driving member 12040 drives the tape clamping jaw 12041 to move, pulling the tape outwards to a defined position. Then, the folding moving assembly 12030 drives the folding jaws 12031 to move towards the tape to return to the working position.

[0113] After the tape is slit, the tape transfer assembly 1230 drives the transfer suction cup 1232 to move above the tape gripper 12041. Then, the transfer lifting assembly 1231 drives the transfer suction cup 1232 to move downward. While the tape gripper 12041 releases the tape, the transfer suction cup 1232 sucks the tape. Then, the tape transfer assembly 1230 drives the tape to move to the tape peeling mechanism 121 to peel the release paper on the tape. The tape peeling mechanism 121 can be an existing tape peeling machine or tape peeling device, which is an existing technology and can achieve the peeling of the tape. The tape peeling mechanism 121 can also be a manual bench peeling machine or a semi-automatic peeling machine, which is convenient for tape peeling.

[0114] After the tape is peeled, the transfer suction cup 1232 transfers the tape to the tape stage 122. There can be four tape stages 122 in this embodiment. The four tape stages 122 are all located on the stage moving slide rail 125, and the tape stage 122 can be driven by a cylinder to slide on the stage moving slide rail 125, so as to adjust the position of the tape stage 122.

After the tape is transferred to the tape stage 122, the tape is sucked by the tape suction cup and attached to the bus bar to fix the above-mentioned L-shaped bus bar, long U-shaped bus bar and short U-shaped bus bar to the glass on the battery string.

[0115] The embodiment of the present application can automatically bend the L-shaped and U-shaped bus bars, and can realize the laying and sticking fixation of the bus bars, which improves the work efficiency and increases the yield rate at the same time.

[0116] As Figure 1 、 Figure 19 、 20 shown, the automated battery string production line further includes a pre-laying machine 60. After the bus bar is laid on the battery string, the battery string is then conveyed to the pre-laying machine 60 to transfer the battery string to the FR4 board.

The plurality of alignment sensors are all arranged in the alignment area, and the plurality of alignment sensors can be respectively located on the upper and lower sides of the alignment area. The sensors located on the upper and lower sides of the alignment area correspond to each other, and one of them is a transmitting-end sensor and the other is a receiving-end sensor. In one embodiment, the alignment sensor can be a transmissive laser sensor, and the laser beam can be parallel to the plane of the battery string and is highly aligned with the edge of the battery string. After the battery string is placed in the alignment area, it can be determined whether alignment is required according to whether the laser beam is covered. When alignment is required, the position of the battery string can be adjusted by the pre-laying manipulator 62.

[0118] After the battery string is aligned, the pre-laying manipulator 62 sucks the battery string and places it on the FR4 board of the FR4 board conveyor line 644, and then the glass at the lower part of the battery string is adhered to the FR4 board by tape. The pre-laying manipulator 62 includes a pre-laying six-axis robot 621 and a plurality of battery string suction cups 622.

[0119] The third tape feeding device 63 includes a plurality of tape feeding and peeling machines 630. The FR4 board conveyor line 644 is located between the third tape feeding device 63 and the battery string alignment device 61. Preferably, the number of the tape feeding and peeling machines 630 can be three. The third tape feeding device 63 further includes a tape feeding slide rail 631. The three tape feeding and peeling machines 630 are all slidably connected to the feeding slide rail through sliders, and the detachable connection between the tape feeding and peeling machine 630 and the tape feeding slide rail 631 can be realized by adjusting bolts or the like.

A release paper collecting reel 635 rotatably connected to the tape feeding base 632 through a rotating shaft is also provided on the tape feeding base 632.

[0121] When the tape loading and peeling machine 630 is working, the roll-shaped tape is placed on the tape reel 632. One end of the tape is placed on one side of the tape peeling machine. The release paper on the tape is placed in the gap between the tape peeling knife 634 and the tape peeling main body 633, and one end of the release paper passes through the release paper guiding shaft and is then placed on the release paper collecting reel 635. When loading the tape, the tape is advanced forward to separate the tape from the release paper, and then the tape can be sucked by the battery string suction cup 622 on the six-axis robot 130. Three tapes can be grabbed at one time, so as to paste from three different positions. There are multiple tape segments on the tape roll, and the adjacent tape segments are not adhered to each other. Therefore, it is not necessary to cut the tape after peeling the release paper.

[0122] In one embodiment, when the loading speed of the battery string is faster than the pasting speed of the tape, the battery string can be temporarily stored first.

The stacking lifting component is connected to the stacking box 651, and the stacking lifting component drives the stacking box 651 to move up and down. Along the height direction of the stacking box 651, a plurality of stacking positions 6510 are provided on the stacking box 651. When the loading speed of the battery string is faster than the pasting speed of the tape, the pre-laying manipulator 62 can place the battery string layer by layer in the stacking positions 6510 of the stacking box 651 for storage, and then the stacking lifting component drives the stacking box 651 to move downward. When the battery string on the stacking box 651 is needed, the stacking lifting component drives the stacking box 651 to move upward and out. The stacking lifting component can be a cylinder.

[0123] As Figure 1 、 Figures 21 to 24 shown, in one embodiment, the automated battery string production line further includes a stacking repair device 70. After the battery string is placed on the FR4 board of the FR4 board conveyor line 644, the FR4 board conveyor line 644 is connected to the battery string conveyor line 40, and then the battery string conveyor line 40 conveys the battery string to the stacking repair device 70. The stacking repair device 70 is located between the pre-laying machine 60 and the bus bar welding machine 30. The stacking repair device 70 is used to detect the battery string conveyed by the pre-laying machine 60 to determine whether the battery string is a qualified product. The battery string conveyor line 40 passes through the middle of the stacking repair device 70.

[0124] The stacking repair device 70 includes a camera detection module 71, a repair moving module 72, a repair table 73 and a stacking lifter 74. The camera detection module 71 is arranged above the battery string conveyor line 40, the repair table 73 is arranged on the side of the battery string conveyor line 40, the repair moving module 72 is arranged between the battery string conveyor line 40 and the repair table 73, and the stacking lifter 74 is arranged on one side of the battery string conveyor line 40.

[0125] During operation, when the battery string is conveyed below the camera detection module 71, the camera detection module 71 takes pictures for detection. If the battery string is detected to be qualified, it is conveyed out along the battery string conveying line 40. If the battery string is detected to be an NG product, the NG product battery string is transferred to the repair table for manual repair by the repair mobile module 72. During the repair process, the battery string conveying line 40 and the camera detection module 71 continue to work. If the battery string is detected to be an NG product again, it is stacked by the stack lifter 74. After the repair on the repair table is completed, the NG product battery string stacked in the stack lifter 74 is transferred to the repair table by the repair mobile module 72 for continuous repair.

[0126] When detecting the battery string, it mainly detects the busbars on the battery string to check whether the positions of the busbars on the battery string are installed in place.

[0127] The stack repair device 70 includes a plurality of alignment modules 75. The plurality of alignment modules 75 are respectively arranged on both sides of the battery string conveying line 40. The alignment module 75 is used to align the battery string on the battery string conveying line 40 to facilitate the detection by the camera detection module 71.

[0128] In an embodiment, in order to align the battery string, the alignment module 75 may include an alignment cylinder 751, an alignment roller 752 and a roller fixing plate 753. Among them, the cylinder shaft of the alignment cylinder 751 is connected to the roller fixing plate 753, and the alignment roller 752 is connected to the roller fixing plate 753 through a rotating shaft or the like. The alignment module 75 drives the alignment roller 752 to move towards or away from the battery string conveying line 40 through the alignment cylinder 751, so as to align the battery string.

[0129] The stack repair device 70 includes a repair frame 76. The alignment module 75, the camera detection module 71, the repair mobile module 72, the repair table 73 and the stack lifter 74 are all located on the repair frame 76. The repair frame 76 is used for supporting and installation. The alignment module 75, the camera detection module 71, the repair mobile module 72, the repair table 73 and the stack lifter 74 can be fixed to the repair frame 76 by fixing methods such as screws. The fixing method is not specifically limited.

[0130] The battery string conveyor line 40 located within the repair rack 76 is configured as two four-section conveyor belts. It should be noted that the battery string itself is relatively long. By using two four-section conveyor belts, the battery string is supported and conveyed across the two conveyor belts. The four-section conveyor belt has three gaps. When being inspected, the battery string longitudinally spans the three gaps to ensure the smooth conveyance of the battery string. Due to the existence of the three gaps in the four-section conveyor belt, it is convenient to subsequently arrange three groups of handling bodies 724 and the stacking positions 6510 on the stacking brackets 744. It should be noted that the four-section conveyor belt means that each complete conveyor belt is composed of four small sections of conveyor belts, and there are gaps between each small section of conveyor belt. Among them, the conveyor belt can be driven by a motor to move the belt, thereby realizing the conveyance of the battery string.

[0131] Specifically, the camera inspection module 71 includes three groups of CCD cameras. By taking pictures with the three groups of CCD cameras and comparing the photos with the preset positions, it can be known whether the laying position of the bus bars on the battery string meets the requirements. If not, it is judged as a NG product. The three groups of CCD cameras can all be fixed to the rack through fixing brackets and the like.

[0132] The repair moving module 72 includes a motorized linear guide 721, a guiding track 722, a support plate 723, and a handling body 724. The support plate 723 is in driving connection with the motorized linear guide 721 and is slidably connected to the guiding track 722. There are three groups of handling bodies 724, and the three groups of handling bodies 724 are all arranged on the support plate 723. The three groups of handling bodies 724 are all composed of a support column 7241, a lifting cylinder 7242, and a lifting plate 7243. The three groups of handling bodies 724 are respectively arranged within the gaps of the two four-section conveyor belts. Among them, the support column 7241 is fixed to the support plate 723 through screws and the like, the lifting cylinder 7242 is fixed to the support column 7241, and the lifting cylinder 7242 is connected to the lifting plate 7243 and drives the lifting plate 7243 to lift and lower. During operation, the motorized linear guide 721 drives the support plate 723 to move back and forth on the guiding track 722, and the battery string is handled through the lifting of the handling body 724. That is, when a NG product of the battery string is detected, the lifting cylinders 7242 of the three groups of handling bodies 724 located in the three gaps of the four-section conveyor belt start to work, causing the lifting plate 7243 to lift and raise the NG product battery string. Then the motorized linear guide 721 is activated to transfer the lifting cylinders 7242 and the lifting plate 7243 on the support plate 723 to the inspection table. The battery string is transferred to the inspection table along with the lifting plate 7243. Then the lifting cylinder 7242 lowers the lifting plate 7243, and the battery string is placed on the inspection table for inspection. The motorized linear guide 721 is a linear guide driven by a motor or integrated with a motor to achieve linear drive.

[0133] The repair station 73 includes a workbench, on which a handling avoidance groove is provided. The function of the handling avoidance groove is to allow the three groups of handling bodies 724 to avoid when entering the workbench and facilitate the three groups of handling bodies 724 to place the battery string on the workbench. The stack lifter 74 includes a stepping motor 741, a transmission belt 742, a support frame 743 and a stack bracket 744. The stepping motor 741 is drivingly connected to the stack bracket 744 through the transmission belt 742. Slide rails are provided on both sides of the support frame 743, and the stack bracket 744 is slidably connected to the slide rails. A number of stack columns 745 are provided on the stack bracket 744, and a stack position 746 is formed between two adjacent stack columns 745. The stack position 746 is arranged within the gap between two four-section conveyor belts. It should be noted that there are three columns of stack columns 745 on the stack bracket 744. The three columns of stack columns 745 correspond to the three gaps of the four-section conveyor belt. The same horizontal position of the three columns of stack columns 745 together forms a stack position 746 for stacking one NG product battery string. When the repair table is working, the repair moving module 72 no longer transfers the NG product battery string to the repair table. At this time, the stack lifter 74 stacks. The stack position 746 itself overlaps with the three gaps, that is, the NG product battery string is between two adjacent stack columns 745. At this time, the stepping motor 741 drives the transmission belt 742 to move, thereby driving the stack bracket 744 to lift, lifting the NG product battery string for stacking. After lifting, the next stack position 746 automatically overlaps with the three gaps. When the next battery string enters the inspection and an NG product appears, the above steps are repeated to stack in this way.

[0134] The stack lifter 74 is provided with twenty stack positions 746. After the battery string at the to-be-repaired station is repaired, an instruction can be sent to enable the repair moving module 72 to transfer the NG product battery string from the stack lifter 74 into the repair table for continued repair, and the stack lifter 74 can perform an adaptive descending action.

[0135] Such as Figure 1 、 Figure 25 、 26 As shown in

[0136] The tape - sticking machine 80 further includes an alignment mechanism and a CCD camera group 83. The alignment mechanism is arranged around the battery string conveyor line 40, the tape - sticking manipulator 82 is arranged above the battery string conveyor line 40, the CCD camera group 83 is arranged above the battery string conveyor line 40, and the tape feeding system 81 is arranged on the side of the battery string conveyor line 40.

[0137] During operation, the battery string is conveyed to the tape - sticking machine 80 through the battery string conveyor line 40. The alignment mechanism initially aligns the position of the battery string. When the battery string is conveyed below the CCD camera group 83, the CCD camera group 83 takes pictures for comparison and cooperates with the alignment mechanism to perform further position correction. In addition, the CCD camera group 83 can also determine whether the incoming battery string is a NG product. Then, the tape - sticking manipulator 82 adsorbs four large tapes one by one and transfers them to the designated position of the battery string for sticking, and then the tape - sticking manipulator 82 adsorbs three small tapes one by one and mounts them at the designated position of the battery string.

[0138] Specifically, the alignment mechanism includes a long - side alignment mechanism 84 and a short - side alignment mechanism 85. The long - side alignment mechanism 84 is arranged on the left and right sides of the battery string conveyor line 40, and the short - side alignment mechanism 85 is arranged on the front and back sides of the battery string conveyor line 40. The long - side alignment mechanism 84 is used to align the two long sides of the battery string, while the short - side alignment mechanism 85 aligns the front and back short sides of the battery string.

[0139] The short - side alignment mechanism 85 includes a position - adjusting cylinder 851, a lifting cylinder 852, and an alignment wheel 853. The lifting cylinder 852 is connected to the movable end of the position - adjusting cylinder 851, and the alignment wheel 853 is arranged on the movable end face of the lifting cylinder 852. During operation, when the battery string enters from the battery string conveyor line 40, the lifting cylinder 852 lifts up so that the alignment wheel 853 abuts against the battery string. The alignment wheel 853 can rotate, and the position - adjusting cylinder 851 cooperates with the CCD camera group 83 to adjust the position for position correction. When the correction is completed, the lifting cylinder 852 drives the alignment wheel 853 to descend to make way so that the battery string can pass through and be conveyed to the next process. It should be noted that the structure of the long - side alignment mechanism 84 is similar to that of the short - side alignment mechanism 85, except that the alignment wheel 853 on the long - side alignment mechanism 84 only needs to move horizontally in the front - back and left - right directions on the same plane and does not need to be lifted. In some cases, in order to ensure that the alignment wheel 853 on the long - side alignment mechanism 84 is flush with the battery string, an additional lifting cylinder 852 can also be set, which will not be elaborated here.

[0140] Limit mechanisms 86 are provided on both the position - adjusting cylinder 851 and the lifting cylinder 852. The limit mechanisms 86 are used to limit the position - adjusting cylinder 851 and the lifting cylinder 852.

[0141] Specifically, the limit mechanism 86 may include a limit switch and a limit plate. The limit plate is connected to the adjustment cylinder 851 or the lifting cylinder 852, and the limit plate is driven to move by the adjustment cylinder 851 or the lifting cylinder 852. During the movement of the limit plate, the position of the limit plate is limited by the limit switch, thereby realizing the limit function.

[0142] The CCD camera group 83 includes a first CCD camera, a second CCD camera, and a third CCD camera. The CCD camera group 83 takes pictures with three groups of CCD cameras to ensure that the entire battery string can be photographed in place.

[0143] In one embodiment, the tape feeding system 81 has the same structure as the tape feeding and peeling machine 630 of the third tape feeding device 63, and can automatically complete the feeding of the tape. The structure of the tape feeding system 81 will not be described in detail here. There are two tape feeding systems 81, and the two tape feeding systems 81 respectively complete the feeding of the large tape and the small tape. The two tape feeding systems 81 are respectively located on both sides of the tape sticking manipulator 82. There are multiple separated tapes on the tape reel 632. After the tape is separated from the release paper, the tape sticking manipulator 82 can directly adsorb the tape. The large tape and the small tape mentioned in this embodiment are relative. The sticking area of the large tape is larger than that of the small tape.

[0144] Specifically, the tape sticking manipulator 82 includes a four-axis robot 820, a large tape suction cup, and a small tape suction cup. The four-axis robot 820 drives the large tape suction cup to successively adsorb four large tapes to the designated position of the battery string for sticking, and the four-axis robot 820 drives the small tape suction cup to successively adsorb three small tapes to the designated position of the battery string for sticking, thereby completing automatic sticking. The four-axis robot 820 is a prior art.

[0145] Such as Figure 2 、 Figures 27 to 29 As shown in the figure, in one embodiment, the automated battery string production line further includes a defective product stacking device 90. The defective product stacking device 90 is located between the tape sticking machine 80 and the bus bar welding machine 30. The defective product stacking device 90 is used to stack defective battery strings. The battery string conveyor line 40 passes through the inside of the defective product stacking device 90.

[0146] The defective product stacking device 90 includes a conveying mechanism 91 and an NG product stacking mechanism 92. The conveying mechanism 91 is arranged at one end of the battery string conveyor line 40. The battery string conveyor line 40 placed inside the defective product stacking device 90 includes a main conveyor line 41 and an auxiliary conveyor line 42. The main conveyor line 41 is two four-section conveyor belts, and the auxiliary battery string conveyor line 40 is a three-section conveyor belt. There is a gap between the two four-section conveyor belts, and the NG product stacking mechanism 92 is arranged in the gap.

[0147] During operation, the battery strings are transported to other workstations through the conveying mechanism 91, and connected with the conveying mechanism 91 through the main conveying line 41 and the auxiliary conveying line 42. During the conveying process, if the CCD camera group 83 detects that the battery string is qualified, it will be transported out from the other end of the battery string conveying line 40. If the battery string is detected to be NG, the NG product stacking mechanism 92 will lift the NG battery strings one by one on the battery string conveying line 40, separate them and stack them.

[0148] Specifically, it also includes a stacking rack 93, in which the conveying mechanism 91 and the NG product stacking mechanism 92 are arranged. When working, the conveying mechanism 91 is extended to connect the battery strings conveyed from other processes. When maintenance is required, the conveying mechanism 91 can be retracted into the stacking rack 93. The conveying mechanism 91 adopts a telescopic design, and can be retracted into the stacking rack 93 when the equipment is under maintenance, so that maintenance personnel can pass through, which has the advantage of being easy to maintain.

[0149] The main conveyor line 41 and the auxiliary conveyor line 42 are both connected by transmission motor 410, main transmission shaft 411 and driven shaft 412. It should be noted that the main conveyor line 41 and the auxiliary battery string conveyor line 40 are both used for the transportation of battery strings. The main conveyor line 41 is mainly used to cooperate with the stacking mechanism for stacking, so it is provided with a gap, and the auxiliary conveyor line 42 is mainly used to adapt to the width of the battery string for support. The main conveyor line 41 and the auxiliary conveyor line 42 are both driven by the motor drive main transmission shaft 411 and the driven shaft 412 and the belt on the battery string conveyor line 40. Specifically, the main transmission shaft 411 is arranged opposite to the slave rotation shaft, and the main transmission shaft 411 and the slave transmission shaft are both rotatably connected to the stacking frame 93, and the conveying motor 410 is connected to the main transmission shaft 411, and the main transmission shaft 411 is connected to the slave transmission shaft through a belt. The conveying motor 410 drives the main transmission shaft 411 to rotate, and the main transmission shaft 411 drives the slave transmission shaft to rotate through the belt. The adjacent auxiliary electric conveyor lines share the same slave transmission shaft, and the three-section conveyor belt of the auxiliary conveyor line 42 can be driven by a conveying motor 410. The main conveyor line 41 is a four-section conveyor belt, and each section of the conveyor belt is driven by a conveying motor 410.

The telescopic end 910 can be driven to slide by a cylinder or the like, or can be manually pushed to slide. The telescopic end 910 is provided with a conveying roller 912 and a conveying guide wheel 913. The fixed end 911 is provided with a travel switch 917 for controlling the sliding and telescoping of the telescopic end 910. The telescopic end 910 can be telescoped along the fixed end 911 and is controlled by the travel switch 917. The conveying roller 912 and the conveying guide wheel 913 on the telescopic end 910 are beneficial to the conveying of the battery string. A grasping handle 914 is arranged in front of the telescopic end 910. By the grasping handle 914, the telescopic end 910 can be pushed to slide, so as to retract into the stacking rack 93. A limit stop 915 for performing telescopic limit on the telescopic end 910 is arranged at the fixed end 911, and the limit stop 915 is used for performing telescopic limit.

[0151] Auxiliary support discs 916 are arranged on both sides of the conveying roller 912, and the auxiliary support discs 916 play a role in conveying support.

[0152] The NG product stacking mechanism 92 is similar in structure to the stacking elevator 74 of the stacking repair device 70. The stacking position 746 of the NG product stacking mechanism 92 is arranged in the gap between two four-section conveyor belts. The structure of the NG product stacking mechanism 92 can refer to the structure of the stacking elevator 74, and will not be specifically described here.

[0153] Specifically, an NG product detection camera 94 is further arranged above the battery string conveying line 40. The NG product detection camera 94 is a CCD camera, and the CCD camera is used to judge whether the battery string is an NG product. The CCD camera can be fixed to the stacking rack 93 through bolts or the like.

[0154] Through the above structure, the present embodiment can automatically lift and stack the NG product battery strings without manual collection. After stacking, the NG product battery strings can be arranged in an orderly manner, which is convenient for subsequent rework operations, is more convenient to use, and has the characteristic of saving labor costs.

[0155] After the non-conforming products are stacked, the remaining qualified product battery strings are conveyed to the bus bar welding machine 30 through the battery string conveying line 40 to realize the welding of the bus bar and the leads of the battery string. The battery string conveying line 40 passes through the inside of the bus bar welding machine 30, so as to realize the conveying of the battery string.

[0156] Such as Figures 30 to 35As shown, the welding correction device 31 includes a long side correction mechanism 310 and a short side correction mechanism 311. The long side correction mechanism 310 is arranged on both sides of the battery string conveyor line 40, and the short side correction mechanism 311 is placed at both ends of the battery string conveyor line 40 inside the busbar welding machine 30. The busbar welding device 32 is arranged above the battery string conveyor line 40, and the welding support mechanism is arranged below the battery string conveyor line 40. The battery string conveyor line 40, the long side correction mechanism 310, the short side correction mechanism 311, the busbar welding device 32 and the welding support mechanism are all arranged on the body of the busbar welding machine 30.

[0157] The busbar welding machine 30 further includes a fume extraction duct 34 for exhausting welding fumes, which is disposed above the battery string conveying line 40.

[0158] The long side alignment mechanism 310 includes a long side telescopic cylinder 3101 and a long side alignment guide wheel 3102. The long side alignment guide wheel 3102 is connected to the movable end of the long side telescopic cylinder 3101 by transmission. The long side alignment guide wheel 3102 is used to align the long side. The long side telescopic cylinder 3101 can extend and retract the long side alignment guide wheel 3102. The long side telescopic cylinder 3101 drives the long side alignment guide wheel 3102 to move toward or away from the conveyor belt, thereby aligning the two sides of the FR4 board on the battery string conveyor line 40. There are multiple long side alignment mechanisms 310, and the multiple long side alignment mechanisms 310 are arranged at intervals along the length direction of the battery string conveyor line 40.

[0159] The short side alignment mechanism 311 includes a short side lifting cylinder 3110 and a short side alignment guide wheel 3111. The short side alignment guide wheel 3111 is connected to the movable end of the short side lifting cylinder 3110, and the short side alignment is performed by the short side alignment guide wheel 3111.

There are two short side alignment mechanisms 311, and the two short side alignment mechanisms 311 are arranged opposite to each other. The two short side alignment mechanisms 311 are used to align the two ends of the FR4 board.

[0160] The busbar welding device 32 includes a flux nozzle 321, a welding module 322, and a welding pressing block 323. The flux nozzle 321 is arranged on the side of the welding module 322, and the welding pressing block 323 is connected to the welding module 322. During operation, the flux is added through the flux nozzle 321, and the welding module 322 generates heat to perform compaction welding.

[0161] In one embodiment, the bus bar welding device 32 may further include linear guide modules in the X-axis, Y-axis, and Z-axis directions. The flux nozzle 321, the welding module 322, and the welding pressure block 323 are all connected to the linear guide modules in the three directions and are driven by the linear guide modules to move and adjust their positions. The flux nozzle 321 can be an existing spray valve nozzle. The flux nozzle 321 is connected to the flux storage liquid through a pipeline, and the conveyance of the flux is controlled by a control valve. In this application, the flux is automatically and evenly sprayed onto the lead position through the setting of the flux nozzle 321, and the spraying amount and spraying area can be adjusted. The flux nozzle 321 can also control its height position by setting a cylinder.

[0162] In one embodiment, the bus bar welding device 32 further includes a flux storage assembly 34. The flux storage assembly 34 includes a flux storage barrel 341 and a draw plate 342. Among them, the draw plate 342 is slidably connected to the machine body through a draw slide rail 343, and the flux storage barrel 341 can be fixed to the draw plate 342 by means of welding or bolt connection, etc. When it is necessary to add flux, the draw plate 342 is pulled to pull out the flux storage barrel 341 from the machine body, so as to facilitate the addition of flux. The flux nozzle 321 is connected to the flux storage barrel 341 through a pipeline.

[0163] In one embodiment, the welding module 322 generates high temperature through internal heating elements (electromagnetic induction heating or resistance heating), so as to heat the bus bar and the leads of the battery string to the welding temperature for welding. A temperature sensor 1033 can also be equipped on the welding module 322, and the welding temperature is detected in real time by the temperature sensor 1033 when the welding module 322 is welding. The structure of the welding module 322 can be the prior art.

By means of the detachable connection, the welding pressure block 323 can be replaced according to different specifications of products. The welding pressure block 323 and the welding module 322 can be connected by bolts, etc., so as to facilitate their disassembly. In one embodiment, the welding pressure block 323 can be an elastic pressing head. When the welding module 322 is welding, the twelve leads of the battery cell with a specification of 182 mm individually correspond to the pressing heads. When the welding module 322 is replaced, the six leads or nine leads of the battery cell with a specification of 165 mm can be compatibly welded.

[0165] Specifically, a waste cup can also be provided below the flux nozzle 321. The waste cup is used to receive the flux. Specifically, if the flux is not used for a long time, it will crystallize and cause the nozzle to be blocked. During the equipment shutdown stage, the flux can be sprayed into the waste cup at regular intervals to avoid the crystallization and blockage of the flux nozzle 321.

[0166] Specifically, the welding jacking mechanism includes a jacking cylinder 331 and a jacking block 332. The jacking block 332 is connected to the movable end of the jacking cylinder 331.

Further, the jacking block 332 can be set to multiple pieces according to usage requirements, such as two pieces, three pieces, four pieces, etc. The jacking block 332 cooperates with the hole plate on the FR4 board. When welding the bus bar, the jacking block 332 passes through the hole position 35 on the FR4 board and then jacks open the EPE strip, avoiding the contact between the EPE strip and the FR4 board, and preventing the EPE strip from contacting and bonding with the FR4 board when the bus bar is welded to the FR4 board. Further, an adjustment slide rail is provided at the bottom of the welding jacking mechanism, and the jacking mechanism is slidably connected to the adjustment slide rail. The adjustment slide rail adjusts the position of the welding jacking mechanism to adapt to products of different specifications.

[0167] As Figures 36 to 39 As shown, the automated battery string production line further includes a diode welding machine 100. After the welding of the bus bar and the lead of the battery string is completed, the battery string is then conveyed by a conveyor line to the diode welding machine 100 for diode welding. The diode welding machine 100 is located at the rear end of the bus bar welding machine 30. The diode welding machine 100 includes a diode feeding device 101, a diode gripping manipulator 102, and a diode welding device 103. The diode feeding device 101 is used for feeding diodes.
