Description

Technical Field

[0001] The present application belongs to the technical field of photovoltaic module production, and specifically, relates to a welding ribbon arrangement and clamping device. Background Art

[0002] As the size of photovoltaic modules increases, the number of solder strips required in the manufacturing process of photovoltaic modules also increases, resulting in higher and higher requirements for the arrangement accuracy of solder strips. Existing solder strip handling clamps can hardly meet the high precision and high efficiency required for the arrangement of solder strips for the entire panel of modules.

[0003] In the process of arranging the solder strip, the commonly used clamping device is to open and close two clamps around the rotating axis at the same time or one clamp is fixed and the other clamp is opened and closed around the rotating axis, so as to clamp or place the solder strip on the battery cell or backplane. In the process of clamping the solder strip, the solder strip is easy to adhere to the clamp, which makes it easy to drive the solder strip to move laterally during the opening and closing of the clamp, thereby affecting the accuracy of placing the solder strip on the battery cell or backplane.

[0004] In view of the above problems, the clamping method of withdrawing the clamping claws along the axial direction of the welding ribbon can solve the problem of left and right deviation during the transportation of the welding ribbon. However, due to the small spacing between two adjacent battery cells in the photovoltaic module, that is, the small spacing between the ends of the welding ribbons on two adjacent battery cells, when transporting the entire row of welding ribbons, there is no space for the clamping claws of the two adjacent rows of welding ribbons in the entire row to smoothly detach from the corresponding welding ribbons axially at the same time, and thus the entire string of welding ribbons cannot be transported, and transporting the welding ribbons in sections will greatly reduce the arrangement efficiency.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The present application provides a welding strip arrangement and clamping device, referring to Figure 1-6 , comprising a base 1, a first power output member 2 and at least two clamping assemblies, in the extension direction of the welding strip 5, at least one of the clamping assemblies is provided on both sides of the base 1, each of the clamping assemblies comprises an upper clamping jaw 3 and a lower clamping jaw 4, the upper clamping jaw 3 comprises a plurality of upper clamping portions 31 and an upper mounting plate 32, the plurality of upper clamping portions 31 are mounted on the upper mounting plate 32 along a direction perpendicular to the extension direction of the welding strip 5, the lower clamping jaw 4 comprises a plurality of lower clamping portions 41 and a lower mounting plate 42, the plurality of lower clamping portions 41 are mounted on the lower mounting plate 42 along a direction perpendicular to the extension direction of the welding strip 5, and one of the lower clamping portions 41 is provided below each of the upper clamping portions 31;

[0044] When clamping the welding strip 5, the first power output member 2 drives the lower mounting plate 42 to move laterally, so that all the lower clamping parts 41 on the lower mounting plate 42 move from the side below the welding strip 5 to the bottom of the welding strip 5 at the same time, and can drive the upper mounting plate 32 to move downward, so that all the upper clamping parts 31 on the upper mounting plate 32 move downward at the same time, until each of the upper clamping parts 31 presses the welding strip 5 below it onto the lower clamping part 41 below the welding strip 5, and finally at least two ends of each of the welding strips 5 are clamped by the clamping components arranged on both sides of the base 1;

[0045] When placing the welding strip 5, the first power output member 2 drives the upper mounting plate 32 to move upward, so that all the upper clamping parts 31 on the upper mounting plate 32 move upward at the same time, and can drive the lower mounting plate 42 to move laterally, so that all the lower clamping parts 41 on the lower mounting plate 42 move from below the welding strip 5 to the side below the welding strip 5 at the same time, so that all the welding strips 5 are placed at preset positions.

[0046] In this embodiment, the preset position may be a position corresponding to the battery cell or the adhesive layer on the back panel. If it is a battery cell, the preset position refers to each main grid on the battery cell, and the adhesive layer on the back panel may be an EVA layer.

[0047] In the process of clamping and carrying the solder strip 5, each solder strip arrangement clamping device is provided with at least two clamping components, so that at least two ends of a group of solder strips 5 can be clamped, so as to carry the solder strips 5 to the corresponding battery cell or backplane, where a group of solder strips 5 refers to the solder strips 5 required for a battery cell. Preferably, two clamping components are provided, and in the extension direction of the solder strip 5, the two clamping components are respectively located on both sides of the base 1, one of the clamping components clamps one end of a group of solder strips 5 at the same time, and the other clamping component clamps the other end of a group of solder strips 5 at the same time.

[0048] It can be understood that the solder strip arrangement clamping device of this embodiment can clamp and carry a group of solder strips 5 at one time. When the whole string of solder strips 5 needs to be carried, the number of solder strip arrangement clamping devices can be set according to the number of battery cells in the actual battery string. In this way, the whole string of solder strips 5 can be carried to the corresponding position on the adhesive layer of a battery string or back plate through multiple solder strip arrangement clamping devices, and the arrangement efficiency is high. And because the lower clamping portion 41 moves between the side below the solder strip 5 and the bottom of the solder strip 5, when the whole string of solder strips 5 is placed at the corresponding position on the adhesive layer of the battery string or back plate, the lower clamping portions 41 in the two adjacent solder strip arrangement clamping devices can be smoothly separated from the solder strip 5, so that the whole string of solder strips 5 can be carried out normally.

[0049] When placing the soldering ribbon 5, the upper clamping portion 31 moves upward to separate from the soldering ribbon 5, and the lower clamping portion 41 moves laterally from the bottom of the soldering ribbon 5 to the side below the soldering ribbon 5. In this way, the lateral deviation of the soldering ribbon 5 can be reduced when placing the soldering ribbon 5, so that the soldering ribbon 5 can be arranged on the adhesive layer of the battery cell or the back plate with higher arrangement accuracy.

[0050] The upper clamping portion 31 may be a probe or made of other flexible materials, as long as the upper clamping portion 31 cooperates with the lower clamping portion 41 to clamp and place the soldering ribbon 5 without damaging the soldering ribbon 5 .

[0051] The lower clamping portion 41 has a high hardness, so that when the upper clamping portion 31 presses the welding ribbon 5 onto the lower clamping portion 41, the lower clamping portion 41 will not be deformed due to the downward pressure of the upper clamping portion 31, ensuring that the welding ribbon 5 can be clamped by the upper clamping portion 31 and the lower clamping portion 41. In addition, the thickness of the lower clamping portion 41 is relatively thin, so that in the process of placing the welding ribbon 5, the height difference between the welding ribbon 5 and the adhesive layer of the battery cell or the back plate can be made smaller, thereby reducing the degree of deviation of the welding ribbon 5 during the falling process. Preferably, the thickness of the lower clamping portion 41 is less than 0.5 mm.

[0052] In this embodiment, the first power output member 2 can be four cylinders, and each cylinder drives a lower mounting plate 42 or an upper mounting plate 32 to move. When clamping the welding strip 5, the corresponding cylinder first drives the corresponding lower mounting plate 42 to move horizontally, so that the lower clamping part 41 moves from the lower side of the corresponding welding strip 5 to the bottom of the welding strip 5, and then the corresponding cylinder drives the corresponding upper mounting plate 32 to move downward until the upper clamping part 31 presses the corresponding welding strip 5 onto the lower clamping part 41 below it. In this process, the upper mounting plates 32 in the two clamping assemblies can move at the same time or at different times, and the lower mounting plates 42 in the two clamping assemblies can also move at the same time or at different times, as long as both ends of each welding strip 5 are clamped in the end; when placing the welding strip 5, the lower mounting plates 42 clamped by the two clamping assemblies After the welding ribbon 5 moves to above the adhesive layer of the battery cell or the back panel and is located at the preset position, under the action of the corresponding air cylinder, the upper clamping part 31 moves upward to separate it from the welding ribbon 5, and then under the action of the corresponding air cylinder, the lower clamping part 41 moves laterally, so that the lower clamping part 41 moves from under the corresponding welding ribbon 5 to the side under the welding ribbon 5. At this time, the welding ribbon 5 is completely separated from the clamping assembly and falls to the corresponding position on the adhesive layer of the battery cell or the back panel. In this process, similarly, the upper mounting plates 32 in the two clamping assemblies can move simultaneously or at different times, and the lower mounting plates 42 in the two clamping assemblies can also move simultaneously or at different times.

[0053] The method and device for moving the solder ribbon 5 clamped by the clamping assembly to above the adhesive layer of the battery cell or the back plate are both prior arts and will not be described in detail here.

[0054] Alternatively, the first power output member 2 may simultaneously drive the upper clamping portion 31 to move up and down and the lower clamping portion 41 to move laterally. This embodiment preferably adopts this method to clamp the welding strip 5.

[0055] Specifically, Figure 5 As shown, a cam follower 33 is mounted on the upper mounting plate 32, and a guide groove 43 is provided on the lower mounting plate 42, wherein the upper portion of the guide groove 43 is inclined and the lower portion of the guide groove 43 is vertically arranged;

[0056] When clamping the welding strip 5, the first power output member 2 drives the upper mounting plate 32 to move downward, and the cam follower 33 moves from the upper end to the lower end of the guide groove 43, so that the lower clamping portion 41 moves from the side below the welding strip 5 to the bottom of the welding strip 5, and at the same time, the upper clamping portion 31 moves downward until the upper clamping portion 31 presses the welding strip 5 onto the lower clamping portion 41 below the welding strip 5;

[0057] When placing the welding strip 5, the first power output member 2 drives the upper mounting plate 32 to move upward, and the cam follower 33 moves from the lower end to the upper end of the guide groove 43, so that the upper clamping portion 31 moves upward, and at the same time, the lower clamping portion 41 moves from below the welding strip 5 to the side below the welding strip 5.

[0058] The first power output member 2 of this embodiment directly drives the upper mounting plate 32 to move up and down, and indirectly drives the lower mounting plate 42 to move laterally.

[0059] When clamping the welding strip 5, the first power output member 2 drives the upper mounting plate 32 to move downward, and the cam follower 33 first moves in the upper part of the guide groove 43 where the welding strip 5 is inclined, so that the lower mounting plate 42 moves laterally while the upper mounting plate 32 moves downward, that is, during the downward movement of the upper clamping portion 31, the lower clamping portion 41 moves from the side below the welding strip 5 to the bottom of the welding strip 5; then the first power output member 2 continues to drive the upper mounting plate 32 to move downward, so that the cam follower 33 enters the lower part of the guide groove 43 where the welding strip 5 is vertically arranged, at which time the lower mounting plate 42 no longer moves laterally, and the lower clamping portion 41 is always located below the welding strip 5, and the first power output member 2 drives the upper mounting plate 32 to move downward until the upper clamping portion 31 presses the welding strip 5 onto the lower clamping portion 41 below it. In this process, the length of the lower part of the guide groove 43 should be sufficient to allow the upper clamping portion 31 to move downward until the welding strip 5 is pressed onto the lower clamping portion 41.

[0060] When placing the welding ribbon 5, the first power output member 2 drives the upper mounting plate 32 to move upward, and the cam follower 33 first moves in the lower part of the guide groove 43. At this time, the lower clamping portion 41 does not move, and the upper clamping portion 31 moves upward; then the first power output member 2 continues to drive the upper mounting plate 32 to move upward, so that the cam follower 33 enters the upper part of the guide groove 43. At this time, the lower mounting plate 42 moves laterally, and the upper mounting plate 32 continues to move upward, that is, the lower clamping portion 41 moves from the bottom of the welding ribbon 5 to the side below the welding ribbon 5, and the upper clamping portion 31 continues to move upward, so that the welding ribbon 5 is separated from the lower clamping portion 41 and placed on the adhesive layer of the battery cell or the back plate.

[0061] The inclination angle of the upper part of the guide groove 43 can be set according to the actual needs to make the lower clamping part 41 move horizontally. This angle enables the lower clamping part 41 to be located just below the corresponding welding strip 5 when the cam follower 33 just moves from the upper part of the guide groove 43 to the lower part.

[0062] like Figure 1As shown, during the process of clamping and placing the welding strip 5 , the upper mounting plate 32 is movably connected to the base 1 via the vertical guiding element 11 , and the lower mounting plate 42 is movably connected to the base 1 via the horizontal guiding element 12 .

[0063] The vertical guide element 11 and the horizontal guide element 12 can be in the form of guide rails with sliders, or can be linear motion components such as guide rods and linear bearings. This embodiment is further described by taking guide rails with sliders as an example.

[0064] Specifically, refer to Figure 1 , the vertical guide element 11 includes a vertical guide rail 111 and a vertical slider 112, the vertical guide rail 111 is vertically mounted on the base 1, the vertical slider 112 is mounted on the upper mounting plate 32, and the vertical slider 112 is slidably connected to the vertical guide rail 111, and in the process of the upper mounting plate 32 moving up and down, the vertical slider 112 slides up and down on the vertical guide rail 111, so that the upper mounting plate 32 slides up and down relative to the base 1. In the process of the upper mounting plate 32 moving up and down, the setting of the vertical guide rail 111 and the vertical slider 112 can guide the movement of the upper mounting plate 32, further ensure the arrangement accuracy of the welding strip 5, and ensure that the clamping assembly can smoothly clamp the welding strip 5. Alternatively, the vertical guide rail 111 can be vertically mounted on the upper mounting plate 32, the vertical slider 112 is mounted on the base 1, and the vertical slider 112 can be slidably mounted on the vertical guide rail 111. In this embodiment, the vertical guide element 11 is preferably set in the latter way.

[0065] It is understandable that each upper mounting plate 32 is slidably connected to the base 1 via a vertical guide element 11. Preferably, each upper mounting plate 32 is slidably connected to the base 1 via two vertical guide elements 11, and two vertical guide rails 111 are vertically disposed on both sides of the upper mounting plate 32, respectively.

[0066] The horizontal guide element 12 includes a horizontal guide rail 121 and a horizontal slider 122. The horizontal guide rail 121 is horizontally mounted on the base 1, and the horizontal slider 122 is mounted on the lower mounting plate 42. The horizontal slider 122 is slidably connected to the horizontal guide rail 121. During the lateral movement of the lower mounting plate 42, the horizontal slider 122 slides horizontally on the horizontal guide rail 121, so that the lower mounting plate 42 slides horizontally relative to the base 1. During the lateral movement of the lower mounting plate 42, the setting of the horizontal guide rail 121 and the horizontal slider 122 can guide the movement of the lower mounting plate 42, ensuring that the clamping assembly can smoothly clamp the welding strip 5. Alternatively, the horizontal guide rail 121 can be horizontally mounted on the upper mounting plate 42, the horizontal slider 122 is mounted on the base 1, and the horizontal slider 122 is slidably mounted on the horizontal guide rail 121. The present embodiment preferably adopts the former method to set the horizontal guide element 11.

[0067] It is understandable that each lower mounting plate 42 is slidably connected to the base 1 through a horizontal guide element 12. Preferably, each lower mounting plate 42 is slidably connected to the base 1 through at least two horizontal guide elements 12, and horizontal guide rails 121 are installed on at least both sides of the base 1 in a direction perpendicular to the extending direction of the welding strip 5.

[0068] like Figure 1 , 2 As shown in 4, in the extension direction of the welding strip 5, both sides of the base 1 are provided with a limit plate 6, the bottom of the limit plate 6 has a plurality of bosses 61, an opening 62 is formed between two adjacent bosses 61, and both ends of each welding strip 5 are respectively located in the corresponding opening 62;

[0069] When placing the welding ribbon 5, the bottom of the boss 61 is close to the adhesive layer of the battery cell or the back plate, and both ends of the welding ribbon 5 fall along the side wall of the boss 61 to the preset position for reference. Figure 6 .

[0070] The top of the limiting plate 6 is installed on the base 1. When the upper clamping portion 31 and the lower clamping portion 41 cooperate with each other to clamp the corresponding welding strip 5, the end of the welding strip 5 is located in the opening 62. After the welding strip 5 clamped by the clamping assembly is moved to the top of the corresponding position of the adhesive layer of the battery cell or the back plate, when the welding strip 5 is placed, the bottom of the boss 62 is close to the battery cell or the back plate, and then when the clamping assembly releases the welding strip 5, the welding strip 5 falls along the side wall of the corresponding boss 62 to the adhesive layer of the battery cell or the back plate. In this way, it can be avoided that the lower clamping assembly 41 leaves the bottom of the welding strip 5 and drives the welding strip 5 to move horizontally, thereby ensuring that the arrangement of the welding strip 5 has a higher precision.

[0071] It can be understood that the two ends of each welding strip 5 are respectively located in the openings 62 of the limiting plates 6 on both sides of the base 1. When placing the welding strip 5, the two ends of each welding strip 5 fall along the side walls of the corresponding boss 62 onto the adhesive layer of the battery cell or the back panel.

[0072] like Figure 1-4 As shown, a connecting plate 7 is provided on the top of the base 1 , and the base 1 and the connecting plate 7 are connected via a leveling bolt 71 .

[0073] Specifically, the connecting plate 7 and the base 1 are connected by four leveling bolts 71, and the four leveling bolts 71 are respectively arranged at the four corners of the connecting plate 7 and are symmetrically arranged. The position of the base 1 relative to the connecting plate 7 can be adjusted by adjusting the leveling bolts 71, so that the base 1 is in a horizontal state, that is, the clamping assembly has good colinearity, that is, all the upper clamping parts 31 on the welding strip arrangement clamping device are located on the same horizontal straight line, and all the lower clamping parts 41 are also located on the same horizontal straight line, so that a group of welding strips 5 can be clamped at the same time, so that each welding strip 5 is subjected to uniform force when clamped.

[0074] like Figure 2 As shown, the first power output member 2 includes a first rotating shaft 21, two first pressure wheels 22 and a first spring 23, the two first pressure wheels 22 are respectively fixedly mounted on both ends of the first rotating shaft 21, and a first pressure wheel 22 is disposed above each of the upper mounting plates 32;

[0075] The lower mounting plate 42 is located below the base 1, the upper mounting plate 32 passes through the base 1, the top of the upper mounting plate 32 is located above the base 1, the bottom of the upper mounting plate 32 is located below the base 1, the upper clamping portion 31 is installed at the bottom of the upper mounting plate 32, one end of the first spring 23 is connected to the top of the upper mounting plate 32, and the other end is connected to the base 1;

[0076] The first rotating shaft 21 rotates to drive the first pressure wheel 22 to gradually apply a downward force to the upper mounting plate 32 below it, so that the upper mounting plate 32 moves downward, or the first rotating shaft 21 rotates so that the downward force applied by the first pressure wheel 22 to the upper mounting plate 32 below it gradually returns to zero, so that the upper mounting plate 32 moves upward.

[0077] In this embodiment, the upper mounting plate 32 and the base 1 are movably connected via the vertical guide element 11. One end of the first spring 23 is connected to the middle of the top of the upper mounting plate 32, and the other end is connected to the base 1. At the position where the first spring 23 is set, the upper mounting plate 32 has an accommodating cavity to accommodate the first spring 23.

[0078] When the welding strip 5 needs to be clamped, the first rotating shaft 21 rotates, driving the two first pressure wheels 22 to gradually apply downward force to the corresponding upper mounting plate 32 at the same time, so that all the upper clamping parts 31 move downward at the same time, and all the lower clamping parts 41 move from the side below the corresponding welding strip 5 to the bottom of the welding strip 5 at the same time, that is, under the action of the first power output member 2, the two clamping components clamp the two ends of a group of welding strips 5 at the same time. In this process, the vertical slider 112 slides downward along the vertical guide rail 111 to play a guiding role. And due to the downward force applied by the first pressure wheel 22 to the upper mounting plate 32, the first spring 23 is gradually compressed.

[0079] When the soldering ribbon 5 needs to be placed on the battery cell or back plate, the first rotating shaft 21 rotates in the opposite direction to the rotation direction when clamping the soldering ribbon 5, so that the downward force applied by the first pressing wheel 22 to the corresponding upper mounting plate 32 gradually returns to zero, that is, the two clamping components simultaneously loosen the two ends of all the soldering ribbons 5 in a group of soldering ribbons 5, so that a group of soldering ribbons 5 are placed on the adhesive layer of the battery cell or back plate at the same time. In this process, the first spring 23 gradually returns to the initial state, so that the upper mounting plate 32 moves upward.

[0080] like Figure 1 , 3 As shown, it also includes a first pressing assembly 8 and a second pressing assembly 9, the first pressing assembly 8 includes a second power output member 81 and a first pressing plate 82, the first pressing plate 82 is located below the middle of the base 1, and along a direction perpendicular to the extending direction of the welding strip 5, a plurality of first pressing portions 821 are installed on the first pressing plate 82, and each of the first pressing portions 821 is arranged corresponding to one of the welding strips 5;

[0081] The second pressing assembly 9 includes a third power output member 91 and two second pressing plates 92. Along the extension direction of the welding strip 5, the two second pressing plates 92 are respectively located below the two sides of the base 1. Along the direction perpendicular to the extension direction of the welding strip 5, each of the second pressing plates 92 is installed with a plurality of second pressing portions 921. Each of the second pressing portions 921 on each of the second pressing plates 92 corresponds to one of the welding strips 5.

[0082] When placing the welding ribbon 5, the second power output member 81 drives the first pressing plate 82 to move downward until each of the first pressing portions 821 presses the middle of the welding ribbon 5 thereunder on the adhesive layer of the battery cell or the back panel, and then the clamping assembly releases the welding ribbon 5, and then the third power output member 91 drives the two second pressing plates 92 to move downward at the same time until each of the second pressing portions 921 in one of the second pressing plates 92 presses one end of the welding ribbon 5 thereunder on the adhesive layer of the battery cell or the back panel, and each of the second pressing portions 921 in the other second pressing plate 92 presses the other end of the welding ribbon 5 thereunder on the adhesive layer of the battery cell or the back panel.

[0083] The specific process of placing the soldering ribbon 5 on the battery cell or backplane in this embodiment is as follows:

[0084] When the welding strip 5 clamped by the clamping assembly moves to a specific position above the adhesive layer of the battery cell or back plate, the second power output member 81 drives the first pressing plate 82 to move downward until each first pressing portion 821 presses the middle of the welding strip 5 below it on the adhesive layer of the battery cell or back plate, and then the clamping assembly releases the welding strip 5, so that the welding strip 5 is placed on the adhesive layer of the battery cell or back plate, and then the third power output member 91 drives the two second pressing plates 92 to move downward at the same time, so that both ends of each welding strip 5 are pressed by the second pressing portion 921 above it. Arranging the welding strip 5 in the above manner can further ensure that the position of the welding strip 5 will not be offset during the arrangement process, thereby improving the arrangement accuracy of the welding strip 5.

[0085] The first pressing part 821 and the second pressing part 921 can be designed in the form of a probe, or a spring, or made of flexible materials such as sponge and silicone. As long as the first pressing part 821 and the second pressing part 921 press the soldering ribbon 5 onto the adhesive layer of the battery cell or the back panel, they will not damage the soldering ribbon 5 and the adhesive layer of the battery cell or the back panel.

[0086] In this embodiment, two mutually parallel first pressing plates 82 may be provided below the middle of the base 1, and the two first pressing plates 82 share a second power output member 81. After the welding ribbon 5 is transported to the corresponding position of the battery cell or the back plate, before the welding ribbon 5 is released, the second power output member 81 drives the two first pressing plates 82 to move downward at the same time until each first pressing portion 821 on each first pressing plate 82 presses the middle of the welding ribbon 5 below it onto the adhesive layer of the battery cell or the back plate, and then the assembly is clamped and the welding ribbon 5 is released.

The first guide member 83 and the second guide member 93 can guide the movement of the first pressing plate 82 and the second pressing plate 92, ensuring that each first pressing portion 821 and each second pressing portion 921 can be pressed on the corresponding welding strip 5.

[0093] The third power output member 91 includes a third rotating shaft 911, two third pressure wheels 912 and two third springs (not shown in the figure), and the two third pressure wheels 912 are fixedly mounted on both ends of the third rotating shaft 911 respectively; the second pressing assembly 9 also includes two second pressure plates 94, each of the second pressure plates 94, each of the third pressure wheels 912 and each of the third springs is arranged corresponding to a second pressing plate 92, each of the second guide members 93 passes through the base 1, and the lower end of each of the second guide members 93 is connected to the corresponding second pressing plate 92, and each The upper ends of the second guide members 93 are connected to the corresponding second pressure plates 94, one end of each of the third springs is connected to the corresponding second pressure plates 94, and the other end is connected to the base 1; the third rotating shaft 911 rotates to drive the third pressure wheel 912 to gradually apply a downward force to the second pressure plate 94 below it, so that the two second pressing plates 92 move downward at the same time, or the third rotating shaft 911 rotates so that the downward force applied by the third pressure wheel 912 to the second pressure plate 94 arranged below it gradually returns to zero, so that the two second pressing plates 92 move upward at the same time.

[0094] In this embodiment, the lower end of the first guide rod 831 is connected to the first pressing plate 82, and the upper end of the first guide rod 831 passes through the first linear bearing 832 and is connected to the first pressing plate 84. When two first pressing plates 82 are provided, the two first pressing plates 82 share one first pressing plate 84, that is, the two first pressing plates 82 are connected to the same first pressing plate 84 through the corresponding first guide rod 831.

[0095] Before releasing the clamping assembly, the second rotating shaft 811 rotates, driving the second pressing wheel 812 to gradually apply downward force to the first pressing plate 84, so that the two first pressing plates 82 move downward at the same time, until each first pressing portion 821 of the two first pressing plates 82 presses the solder strip 5 below it onto the adhesive layer of the battery cell or the back plate. In this process, the second spring is compressed, and the first guide rod 831 moves downward relative to the corresponding first linear bearing 832.

[0096] When it is necessary to separate all the first pressing parts 821 from the corresponding welding strips 5, the second rotating shaft 811 rotates in the direction opposite to the rotation direction of the downward force applied to the first pressure plate 84, so that the downward force applied by the second pressure wheel 812 to the first pressure plate 84 gradually returns to zero. At this time, the first guide rod 831 moves upward relative to the corresponding first linear bearing 832, and the second spring gradually returns to its initial position, so that the two first pressing plates 82 move upward at the same time until they return to their initial positions.

In this process, the third spring is compressed, and the second guide rod 931 moves downward relative to the corresponding second linear bearing 932.

[0099] When it is necessary to separate all the second pressing parts 921 from the corresponding welding strips 5, the third rotating shaft 911 rotates in the direction opposite to the rotation direction of the downward force applied to the second pressure plate 94, so that the downward force applied by the third pressure wheel 912 to the second pressure plate 94 gradually returns to zero. At this time, the second guide rod 931 moves upward relative to the corresponding second linear bearing 932, and the two third springs gradually return to their initial positions, so that the two second pressing plates 92 move upward at the same time until they return to their initial positions.
