[0037] Please refer to Figures 1 to 3 As shown in FIG. 1 , the battery string of an IBC (Interdigitated Back Contact) battery is composed of two rows and multiple columns of battery sheets 10' spread on an FPC film 20'. Before preparing the battery string group, the battery string needs to be cut according to the process. In some special cases, please refer to Figure 4 and Figure 5 As shown, the battery string will be cut into three parts, namely the front string part 13', the waste part 14' and the rear string part 15' (for the convenience of subsequent description, the front string part 13' and the rear string part 14' under different cutting methods are labeled with the same numbers). Among them, the waste part 14' is transferred, and the front string part 13' and the rear string part 15' are laid out to finally form a battery string group after the bus bar 101 is welded. Due to the cutting of the waste part 14', the side of the front string part 13' and the rear string part 15' that was originally connected to the waste part 14' is roughly stepped. At this time, please refer to Figure 6 and Figure 7 As shown, it is necessary to Figure 4 and Figure 5 The rear string portion 15' is turned 180 degrees so that the rear string portion 15' is flipped to a configuration similar to the corresponding front string portion 13' (ie, the stepped sides of both face the same direction), which facilitates the welding of the busbar 101 and the layout of the battery string.

[0038] The edge of the battery string needs to be welded with busbar 101 for drainage. Figure 2 and Figure 3 As shown, due to the presence of two different cutting paths (i.e., the first cutting path 11' and the second cutting path 12'), the battery string includes Figure 1 As shown in the figure, a common battery string with straight lines on both sides, such as Figure 4 and Figure 7 As shown, the left side is a straight line, and the right side is an ascending step-shaped special-shaped battery string (the front string part 13' and the reversed rear string part 15' formed under the second cutting path 12') and Figure 5 and Figure 6 As shown, the left side of the battery string is a straight line, and the right side is a descending step-shaped battery string (the front string part 13' formed under the first cutting path 11' and the rear string part 15' after flipping). In summary, the side of the battery string for welding the bus bar 101 has three different configurations. In order to adapt to the edges of the battery string with different configurations, the present invention provides three different specifications of bus bars 101, namely, a straight bus bar 102 (see Fig.10 As shown), "L" type bus bar 103 (see Figure 8 as shown) and the "R" type bus bar 104 (see Fig. 9 As shown). For the convenience of subsequent description, the straight busbar 102, the "L"-shaped busbar 103 and the "R"-shaped busbar 104 are collectively referred to as the busbar 101, wherein the "L"-shaped busbar 103 and the "R"-shaped busbar 104 are collectively referred to as the special-shaped busbar. Among them, the straight busbar 102 is used to weld with the side of the straight line, and the special-shaped busbar is used to weld with the side in a stepped shape. It should be noted that the terms used in the specific embodiments of the present invention, such as "L" type and "R" type, are only for the convenience of more clearly describing the specific embodiments of the present invention with reference to the drawings in the specification, and do not mean that the busbar 101 itself has the shape shown by the above letters.

[0039] Please refer to Figure 8 and Fig. 9 As shown, the "L" type bus bar 103 and the "R" type bus bar 104 are arranged in a mirror image. Figure 8 , Fig. 9 and Fig.10As shown, the up-down direction in the definition figure is the front-to-back direction, and the left-to-right direction is the left-to-right direction. Different from the straight line setting of the linear busbar 102, the "L"-shaped busbar 103 and the "R"-shaped busbar 104 both include three sections, namely, a middle section 18' perpendicular to the linear busbar 102 and arranged along the left-to-right direction, a first extension section 16' extending backward from one end of the middle section 18' and parallel to the linear busbar 102, and a second extension section 17' extending forward from the other end of the middle section 18' and parallel to the linear busbar 102.

[0040] Please refer to Fig.11 As shown, the present invention discloses a busbar feeding device, which includes a feeding mechanism 100, an extraction mechanism 200, a regulating mechanism 300 and a flux coating mechanism 400, wherein the feeding mechanism 100 is used to lift up the busbar 101 that has been prepared and is ready to be welded with a battery string, so as to facilitate the extraction mechanism 200 to accurately extract the busbar 101 at a fixed position; the extraction mechanism 200 obtains the busbar 101 from the feeding mechanism 100 and transfers it to the regulating mechanism 300; the regulating mechanism 300 corrects the shape and position of the busbar 101; then, the extraction mechanism 200 transfers the regulated busbar 101 to the flux coating mechanism 400, and the flux coating mechanism 400 coats the busbar 101 with flux for welding; then, the extraction mechanism 200 transfers the busbar 101 to the corresponding position of the battery string for welding. In order to adapt to battery strings with different edge configurations, the loading mechanism 100 includes at least two groups, one group is a linear busbar loading mechanism 105 for storing linear busbars 102, and the other group is a special-shaped busbar loading mechanism 106 for storing special-shaped busbars ("L"-shaped busbars 103 or "R"-shaped busbars 104). Of course, in order to adapt to battery strings with more different edge configurations, the loading mechanism 100 can also include three groups, wherein the first group is a linear busbar loading mechanism 105 for storing linear busbars 102, the second group is an "L"-shaped busbar loading mechanism for storing "L"-shaped busbars 103, and the third group is an "R"-shaped busbar loading mechanism for storing "R"-shaped busbars 104.

[0041] Please refer to Figures 12 to 19 As shown, the feeding mechanism 100 includes a tray 11 and a lifting assembly 12. The busbar 101 is stored in the tray 11, and a through hole 110 is opened at the bottom of the tray 11; the lifting assembly 12 includes a push rod 120 and a lifting drive device 130, and the lifting drive device 130 is connected to and drives the push rod 120 to pass through the tray 11 to lift the busbar 101 in the tray 11, so as to facilitate the extraction of the extraction mechanism 200.

[0042] Since the busbar 101 is relatively delicate, in order to better position the busbar 101 so that the lifting assembly 12 can accurately lift the busbar 101 on the tray 11, the tray 11 is provided with a plurality of spaced positioning blocks 111, which are arranged according to the shape of the busbar 101. The busbars 101 are arranged parallel to each other and spaced apart on the tray 11, wherein each busbar 101 is positioned between two adjacent layers of positioning blocks 111.

[0043] For the linear busbar 102, the two layers of positioning blocks 111 corresponding thereto can be arranged relatively in the left-right direction, and the gap between the two layers of positioning blocks 111 extends in the front-to-back direction, just defining the linear busbar 102. Here, the positioning block 111 can be set as a whole extending in the front-to-back direction, or can be set as a plurality of blocks arranged at intervals in the front-to-back direction, as long as the linear busbar 102 can be defined to prevent displacement or deformation. For the linear busbar 102, the through hole 110 corresponding thereto can be set to extend in the left-to-right direction, so as to facilitate the lifting assembly 12 to lift each busbar. Furthermore, the through hole 110 can also be arranged in a plurality of intervals along the extension direction of the linear busbar 102, that is, in the front-to-back direction, and at the same time, a plurality of push rods 120 are also provided, which can simultaneously apply forces to different positions of the linear busbar 102 through a through hole 110, so as to stably lift the linear busbar 102 with a certain length.

[0044] Please refer to Fig.13 and Fig.15As shown, for the special-shaped busbar, the corresponding two-layer positioning blocks 111 can be divided into three groups, which are used to position the first extension section 16', the middle section 18' and the second extension section 17' of the special-shaped busbar. Among them, each group of positioning blocks 111 is respectively arranged on both sides of the non-extended direction of a section of the special-shaped busbar. In this way, on the one hand, the specific position of the busbar 101 can be accurately limited by the size of the positioning block 111 located between two adjacent busbars 101, so that the top rod 120 can accurately lift the corresponding busbar 101; on the other hand, the positioning block 111 can also properly shape the corresponding part of the busbar 101 to reduce possible bending. Furthermore, due to the shape limitation of the special-shaped busbar, when the busbars 101 are arranged in parallel and spaced apart, it is impossible to directly set each busbar 101 in parallel along the left and right direction. In order to place as many special-shaped busbars as possible on the tray 110, it is preferred that each special-shaped busbar is stacked horizontally and parallelly in an inclined direction. Therefore, in order to ensure that when the lifting assembly 12 lifts each busbar 101, the push rod 120 is supported at the same position of the busbar 101 to ensure the stability of the support, the through hole 110 corresponding to the special-shaped busbar extends along the direction of the inclined arrangement of the special-shaped busbar (specifically, the extension direction of the through hole 110 is parallel to the connection direction of the same position on each special-shaped busbar). Furthermore, a plurality of through holes 110 can be provided corresponding to the busbar 101, and at the same time, a plurality of push rods 120 are also provided, which can simultaneously apply force to different positions on the busbar 101 through a through hole 110, so as to stably lift the busbar 101 with a certain length. For details, please refer to Fig.13 As shown, when the push rods 120 lift the "L"-shaped busbar 103, multiple push rods 120 can simultaneously pass through the corresponding through holes 110 to simultaneously apply force to the middle section 18', the first extension section 16' and the second extension section 17', so as to stably lift the "L"-shaped busbar 103 with a certain length.

[0045] The busbars 101 are prepared in advance and stored on the tray 11. When the busbars 101 are used up, the tray 11 needs to be replaced. Figures 13 to 16 As shown, in order to facilitate replacement, a handle 112 is provided on the tray 11 to facilitate manual handling. Preferably, the useless corners of the tray 11 are cut off to reduce weight and facilitate manual handling.

[0046] Please refer to Fig.15As shown, after the material tray 11 is replaced, in order to ensure that the material tray 11 is at the same position every time for loading (that is, to facilitate the lifting component 12 to lift the bus bar 101 at a fixed position, and at the same time, the extraction mechanism 200 can extract the bus bar 101 at a fixed position), the loading mechanism 100 also includes a positioning component 14; the positioning component 14 includes a material table 140 for receiving the material tray 11 and a positioning member for limiting the position of the material tray 11. The material table 140 is provided with an opening 145 located in the middle to facilitate the push rod 120 to push the bus bar 101. The positioning member is arranged on the material table 140. When the material tray 11 is placed on the material table 140, the positioning member can resist the material tray 11. On the one hand, the position of the material tray 11 on the material table 140 is limited, so that the material tray 11 can only fall into the position limited by the positioning member; on the other hand, the displacement of the material tray 11 during the loading process of the bus bar 101 is avoided. In the illustrated embodiment of the present invention, the positioning member includes a first stopper 141, a second stopper 142, a third stopper 143 and a positioning pin 144; wherein the first stopper 141, the second stopper 142, the third stopper 143 and the positioning pin 144 are respectively arranged on the same side (e.g., the upper side) of the material platform 140, and constitute positioning / limiting in four directions of front, back, left and right; a positioning hole 113 is opened on one side of the material tray 11 corresponding to the positioning pin 144. The position deviation of the positioning pin 144 is small, and the matching accuracy with the positioning hole 113 is high; when positioning, the matching of the positioning pin 144 and the positioning block 111 is used as a reference, and the first stopper 141, the second stopper 142 and the third stopper 143 at the other three positions are used to jointly limit the position of the material tray 11 on the material platform 140. In the illustrated embodiment of the present invention, the positioning pin 144 mainly plays a positioning role, and the first stopper 141, the second stopper 142 and the third stopper 143 mainly play a limiting role. Of course, in other embodiments, the positioning member may also be four positioning pins 144, four blocks, or a combination of an appropriate number of positioning pins and an appropriate number of blocks, etc. That is, any structure that can be known to technicians in the relevant technical field and can achieve positioning / limiting of the material tray 11 in the four directions of front, back, left, and right is a reasonable deformation of the positioning member and will not be elaborated here.

[0047] Please refer to Fig.15 and Fig.17 As shown, in order to improve the accuracy and intelligence of the feeding mechanism 100, the feeding mechanism 100 also includes a first detection member 15 for detecting whether the material tray 11 is in place, a second detection member 16 for detecting whether the lifting assembly 12 has pushed the bus bar 101 to a predetermined height, and a third detection member 17 for detecting whether the bus bar 101 has been used up.

[0048] In the illustrated embodiment of the present invention, the lifting assembly 12 is located below the material platform 140. When the busbar 101 needs to be lifted up to facilitate extraction by the extraction mechanism 200, the lifting assembly 12 passes upward through the opening 145 in the middle of the material platform 140 and the through hole 110 at the bottom of the material tray 11. Fig.15 As shown, by providing the first detection member 15, it can be ensured that the lifting assembly 12 will only operate when there is a material tray 11 on the material platform 140. Specifically, a detection plate 114 corresponding to the first detection member 15 is provided on the material tray 11; when the material tray 11 is in place, the detection end of the first detection member 15 is directly opposite to the detection plate 114, wherein the signal emitted by the first detection member 15 is reflected by the detection plate 114 and finally received by the first detection member 15, thereby indicating that the material tray 11 is in place. When the material tray 11 is not in place, the signal emitted by the first detection member 15 cannot be reflected by the detection plate 114, and the first detection member 15 cannot receive the signal, thereby indicating that the material tray 11 is not in place. Preferably, the first detection member 15 is a photoelectric sensor, and the detection plate 114 is a reflective plate. When the material tray 11 is in place and needs to be loaded, the busbar loading device can start the lifting assembly 12 to lift the busbar 101 to facilitate extraction by the extraction mechanism 200.

[0049] After the lifting assembly 12 lifts the busbar 101, the extraction mechanism 200 extracts the busbar 101 and transfers it to the next process. In order to facilitate the extraction mechanism 200 to extract the busbar 101, preferably, the lifting assembly 12 lifts the busbar 101 to the same height each time. To this end, the detection end of the second detection member 16 is located at a set height; after the lifting assembly 12 lifts the busbar 101 and is in place, the second detection member 16 can detect the busbar 101 and transmit the signal to the control system, and the control system controls the extraction mechanism 200 to move and extract the busbar 101. Preferably, the second detection member 16 is a through-beam sensor, which includes a signal transmitting unit and a signal receiving unit, and the transmitting end and the receiving end of the two are opposite. When it is not blocked by the busbar 101, the signal can be transmitted, and the busbar 101 is not in place at this time; when the signal is blocked by the busbar 101, it is known that the busbar 101 is in place.

[0050] The linear busbar 102 has a simple structure, and a number of push rods 120 distributed along the length of the linear busbar 102 can be set to achieve stable lifting. Figure 8 and Fig. 9 As shown, it is formed by several sections; in order to stably lift each section, it is necessary to set several groups of push rods 120 (for example, three groups of push rods 120) to lift each section. Fig.13Taking the "L"-shaped busbar 103 shown in the figure as an example, in order to stably lift the "L"-shaped busbar 103, three groups of push rods 120 include a first group of push rods for lifting the middle section 18', a second group of push rods for lifting the first extension section 16', and a third group of push rods for lifting the second extension section 17'. In addition, since each section of the "L"-shaped busbar 103 and the "R"-shaped busbar 104 has a certain length, each group of push rods 120 preferably includes at least two push rods, so that when lifting the corresponding sections, each group of push rods 120 has at least two contact surfaces with each section to improve the stability of lifting.

[0051] Please refer to Fig.17 As shown, in the illustrated embodiment of the present invention, in order to accommodate the mirror-image arrangement of the "L"-shaped busbar 103 and the "R"-shaped busbar 104, the push rods 120 are arranged in five groups, including a first push rod 121, a second push rod 122 located at one side rear (e.g., left rear) of the first push rod 121, a third push rod 123 located at the other side rear (e.g., right rear) of the first push rod 121, a fourth push rod 124 located at the other side front (e.g., right front) of the first push rod 121, and a fifth push rod 125 located at one side front (e.g., left front) of the first push rod 121. Thus, when the linear busbar 102 is lifted, according to the different positions of the linear busbar 102, the corresponding push rod can be moved to achieve lifting of the linear busbar 102. When the "L"-shaped busbar 103 is lifted, the first push rod 121, the second push rod 122 and the fourth push rod 124 are in motion, wherein the first push rod 121 lifts the middle section 18', the second push rod 122 lifts the first extension section 16', and the fourth push rod 124 lifts the second extension section 17'; when the "R"-shaped busbar 104 is lifted, the first push rod 121, the third push rod 123 and the fifth push rod 125 are in motion, wherein the first push rod 121 lifts the middle section 18', the third push rod 123 lifts the first extension section 16', and the fifth push rod 125 lifts the second extension section 17'. Specifically, the first push rod 121 is used as a reference rod, which is aligned with the middle position of the middle section 18' of the "L"-shaped busbar 103 and the "R"-shaped busbar 104 in the left-right direction. The third detection member 17 is arranged at the end of the first push rod 121, and the third detection member 17 is used to detect whether there is a bus bar 101 above the first push rod 121; when the bus bar 101 is used up, the third detection member 17 cannot detect the existence of an obstruction (i.e., the bus bar 101) above the first push rod 121, and it can trigger an alarm to remind to replace the material tray 11; the third detection member 17 is preferably a proximity sensor.

[0052] Further, the second top rod 122 and the fifth top rod 125 are arranged in the front-to-back direction, and the third top rod 123 and the fourth top rod 124 are arranged in the front-to-back direction. Preferably, the second top rod 122 is aligned with the fifth top rod 125 in the front-to-back direction, and the third top rod 123 is aligned with the fourth top rod 124 in the front-to-back direction. In this way, the second top rod 122 to the fifth top rod 125 are roughly symmetrically arranged outside the first top rod 121, reducing the workload of design and installation. In addition, the above-mentioned first top rod 121 to the fifth top rod 125 are located below the corresponding bus bar 101 and are similar to the configuration of the corresponding bus bar 101 regardless of the configuration alone or in combination with other top rods. At this time, the lifting assembly 12 lifts the linear bus bar 102. According to the different positions of the linear bus bar 102, the first lift rod 121 can be moved, or the second lift rod 122 and the fifth lift rod 125 can be moved, or the third lift rod 123 and the fourth lift rod 124 can be moved to lift the linear bus bar 102.

[0053] In one embodiment of the present invention, the second push rod 122, the third push rod 123, the fourth push rod 124, and the fifth push rod 125 are each provided with an independent driving device 126 to drive the corresponding lifting and lowering thereof, so as to ensure that the corresponding busbar 101 can be lifted. The driving device 126 is preferably a cylinder.

[0054] For further information, see Fig.17 As shown, the second push rod 122, the third push rod 123, the fourth push rod 124, and the fifth push rod 125 all include two push rods spaced apart along the extension direction of a section of the busbar. At this time, two parallel groups of through holes 110 corresponding to a section of the busbar are provided for two push rods to pass through. For example, the two second push rods 122 correspond to the first extension section 16' of the "L"-shaped busbar 103, and the two fourth push rods 124 correspond to the second extension section 17' of the "L"-shaped busbar 103; the two third push rods 123 correspond to the first extension section 16' of the "R"-shaped busbar 104, and the two fifth push rods 125 correspond to the second extension section 17' of the "R"-shaped busbar 104. In this way, when the busbar 101 is lifted, each group of push rods 120 has at least two contact surfaces with the corresponding section of the busbar 101 to improve the stability of the lifting.

[0055] Furthermore, in actual use, the other two sets of push rods used in conjunction with the first push rod 121 are at the same initial height as the first push rod 121, and the two unused sets of push rods are driven by the corresponding drive device 126 to move down to avoid affecting the lifting action. Subsequently, the lifting drive device 130 drives the first push rod 121, the second push rod 122 and the fourth push rod 124 or drives the first push rod 121, the third push rod 123 and the fifth push rod 125 to rise synchronously, and the three sets of push rods contact the bus bar 101 and finally lift the bus bar 101 to a preset height. For details, please refer to Fig.12As shown, the jacking drive device 130 includes a motor 131, a screw rod 132, a guide rod 133 and a jacking platform 134, wherein each group of jacking rods is arranged on the jacking platform 134, and the jacking platform 134 is slidably connected to the guide rod 133 arranged along the vertical direction. At the same time, the jacking platform 134 is threadedly connected to the screw rod 132. Therefore, when the motor 131 drives the screw rod 132 to rotate, it can drive the jacking platform 134 and each group of jacking rods thereon to rise along the guide rod 133 and jack the busbar to a preset height, or descend to avoid a position and prepare to jack up the next group of busbars.

[0056] It should be noted that the lifting assembly 12 of the linear busbar feeding mechanism 105 used for storing linear busbars 102 alone may include only one set of push rods 120, which can stably lift the linear busbars 102 along the extension direction of the linear busbars 102. The special-shaped busbar feeding mechanism 106 used for storing special-shaped busbars is preferably provided with five sets of push rods 120, so that the special-shaped busbar feeding mechanism 106 can perform corresponding lifting actions according to different busbar configurations.

[0057] In the illustrated embodiment of the present invention, a plurality of groups of bus bars 101 are stored on the material tray 11 to improve the working efficiency of the equipment and avoid wasting time due to overly frequent replacement of the material tray 11. When a plurality of groups of bus bars 101 are stored on the material tray 11, it is necessary to lift each bus bar 101 one by one for use. In one embodiment, the material tray 11 remains stationary, and the position adjustment is achieved by moving the push rod 12; in another embodiment, the push rod 12 remains stationary, and the position adjustment is achieved by moving the material tray 11. If the push rod 12 is moved, the position of the push rod 12 may deviate after multiple movements, thereby affecting the lifting accuracy. In order to solve this problem, the feeding mechanism 100 of the present invention also includes a first drive device 18 and a second drive device 19, which are used to drive the material tray 11 to move in the front and back and left and right directions respectively, so that the middle position of the next bus bar 101 is opposite to the first push rod 121 to avoid deviation.

[0058] Specifically, for the special-shaped busbar, in order to ensure that the corresponding through hole 110 is lifted to a relatively fixed position by the ejector rod 120, the material tray 11 needs to be able to move in the front-to-back and left-to-right directions. Fig.12 , Fig.18 and Fig.19As shown, the first drive device 18 / the second drive device 19 can adopt a linear module, wherein the material table 140 is arranged at the output end of the first drive device 18, and the main body of the first drive device 18 is arranged at the output end of the second drive device 19. Thus, the first drive device 18 can drive the material table 140 to move in the left-right direction, and the second drive device 19 can drive the first drive device 18 and the material table 140 to move in the front-back direction; or, the first drive device 18 can drive the material table 140 to move in the front-back direction, and the second drive device 19 can drive the first drive device 18 and the material table 140 to move in the left-right direction. In this way, the material tray 11 can be moved in the front-back and left-right directions to adjust the position.

[0059] For the loading mechanism 100 of the linear bus bar 102, its material tray 11 only needs to move left and right until a new linear bus bar 102 reaches above the top rod 120, and does not need to move forward and backward; therefore, only the first drive device 18 or the second drive device 19 can be set to connect the material tray 11 of the linear bus bar loading mechanism 105 to drive the material tray 11 to move along the left and right direction.

[0060] When the linear busbars 102 are stored, they are positioned between the positioning blocks 111 of two adjacent layers on the tray 11, so that the distance between two adjacent linear busbars 102 remains consistent; then, the tray 11 is positioned on the material table 140; when it is necessary to lift the linear busbars 102, the material table 140 is driven by the driving device to move in the left and right directions, so that a new linear busbar 102 appears within the lifting range of the push rod 120; finally, the lifting drive device 130 drives the push rod 120, so that the push rod 120 passes through the through hole 110 on the tray 11, and lifts the linear busbar 102, so that the extraction mechanism 200 can accurately extract it at a fixed position.

[0061] Please refer to Fig.13 As shown, when the "L"-shaped bus bar 103 is stored, it is positioned between the positioning blocks 111 of two adjacent layers on the material tray 11, so that the distance between the two adjacent "L"-shaped bus bars 103 remains consistent; then, the material tray 11 is positioned on the material table 140; when the "L"-shaped bus bar 103 needs to be lifted, the material table 140 is driven by the first driving device 18 and the second driving device 19 to move in the front-to-back and left-to-right directions to adjust the position until the second push rod 122 is located The first push rod 121 is located below the first extension section 16', the fourth push rod 124 is located below the second extension section 17', and each push rod is located in the corresponding through hole 110; finally, the lifting drive device 130 drives the first push rod 121, the second push rod 122 and the fourth push rod 124 to pass through the through hole 110 on the tray 11 to lift the "L"-shaped bus bar 103, so that the extraction mechanism 200 can accurately extract it at a fixed position.

[0062] The storage and lifting of the “R”-shaped bus bar 104 are similar to those of the “L”-shaped bus bar 103 , and will not be described in detail here.

[0063] Please refer to Fig.11 As shown, in the illustrated embodiment of the present invention, the extraction mechanism 200 is set as two groups, wherein the first group of extraction mechanisms 21 is used to transfer the bus bar 101 from the loading mechanism 100 to the straightening mechanism 300; the second group of extraction mechanisms 22 is used to obtain the bus bar 101 from the straightening mechanism 300 and then transfer the bus bar 101 to the flux coating mechanism 400, and finally move the bus bar 101 to the battery string, thereby improving the operating efficiency of the equipment.

[0064] Please refer to Fig. 20 and Fig.21 As shown, the first group of extraction mechanisms 21 includes an extraction member 210, a first extraction drive member 211 and a second extraction drive member 212, wherein the first extraction drive member 211 is connected to and drives the extraction member 210 to approach or move away from the bus bar 101 or the straightening mechanism 300; the second extraction drive member 212 is connected to and drives the extraction member 210 and the first extraction drive member 211 to move in a horizontal direction to transfer the bus bar 101 to each workstation.

[0065] The extraction member 210 is preferably a vacuum suction cup, the first extraction drive member 211 is preferably a cylinder 2111 and a guide rail 2112, and the second extraction drive member 212 is preferably a linear module.

[0066] Since the “L”-shaped busbar 103 and the “R”-shaped busbar 104 are segmented designs, in order to stably extract each segment of the busbar, the extraction mechanism 200 is provided with three sets of extraction members 210, which respectively extract the middle segment 18', the first extension segment 16' and the second extension segment 17' of the busbar.

[0067] Further, in order to adapt to the two mirror-image busbars of "L" type and "R" type, the extraction mechanism 200 can be provided with five groups of extraction members 210, which include a first extraction member 2101, a second extraction member 2102 located behind one side of the first extraction member 2101, a third extraction member 2103 located behind the other side of the first extraction member 2101, a fourth extraction member 2104 located in front of the other side of the first extraction member 2101, and a fifth extraction member 2105 located in front of one side of the first extraction member 2101. When the "L" type busbar 103 is extracted, the first extraction member 2101, the second extraction member 2102 and the fourth extraction member 2104 are in motion; when the "R" type busbar 104 is extracted, the first extraction member 2101, the third extraction member 2103 and the fifth extraction member 2105 are in motion; in order to ensure that each extraction member 210 can act independently to meet the use requirements, each extraction member 210 is also provided with a separate driving member (preferably a cylinder). Similar to the independent drive of the top rod 12, when extracting the "L"-shaped bus bar 103, the third extractor 2103 and the fifth extractor 2105 remain in the retracted position, and the first extractor 2101, the second extractor 2102 and the fourth extractor 2104 are extended downwardly under the drive of their respective driving members, so that the shape formed by the first extractor 2101, the second extractor 2102 and the fourth extractor 2104 corresponds to the shape of the "L"-shaped bus bar 103; similarly, when extracting the "R"-shaped bus bar 104, the second extractor 2102 and the fourth extractor 2104 remain in the retracted position, and the first extractor 2101, the third extractor 2103 and the fifth extractor 2105 are extended downwardly under the drive of their respective driving members, so that the shape formed by the first extractor 2101, the third extractor 2103 and the fifth extractor 2105 corresponds to the shape of the "R"-shaped bus bar 104.

[0068] For further information, see Fig.11 As shown, the second group of extraction mechanisms 22 includes an extraction member and four groups of drives for driving the extraction member to move. The four groups of drives are respectively an up and down drive member 221 for driving the extraction member to move in the up and down directions, a left and right drive member 222 for driving the extraction member to move in the left and right directions, a front and back drive member 223 for driving the extraction member to move in the front and back directions, and a rotating drive member 224 for driving the extraction member to rotate. The second group of extraction mechanisms 22 is used to extract or release the bus bar 101, transfer it to the next mechanism or to the set position of the battery string. Preferably, the rotating drive member 224 is a motor or an electric motor, which drives the extraction member to rotate to adjust the angle of the bus bar 101 so that it is more suitable for the position of the battery string. The extraction member described in this paragraph is similar in structure to the extraction member 210 in the previous paragraph, and will not be repeated here.

[0069] In the illustrated embodiment of the present invention, since the busbar 101 is prepared in advance and is prepared on the tray 11, it is provided for the extraction mechanism 200 to grasp and transfer to other workstations; in order to facilitate the placement and transfer of the busbar 101, the tray 11 will not completely clamp the busbar 101, and there is a certain gap; therefore, when the busbar 101 is prepared and arranged on the tray 11, the position of the busbar 11 may be offset to a certain extent, and its shape may also be deformed to a certain extent; for this reason, after the extraction mechanism 200 grasps the busbar 101, the shape and position of the busbar 101 are corrected by the correction mechanism 300, and then the extraction mechanism 200 accurately grasps it and transfers it to the next workstation.

The understanding of this specification should be based on the technicians in the relevant technical field. For example, the directional descriptions such as "front", "back", "left", "right", "up", and "down" are described in detail in this specification with reference to the above embodiments.
