Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery production, in particular to an adjusting plate, a solder strip node adjusting device, a solder strip processing device and a method. BACKGROUND

[0002] The solder strip string welding process is an important process in the production process of a solar cell panel, which uses a solder strip to weld cell pieces into a cell string.

[0003] In the current string welding process, one section of the solder strip is usually welded to the back of one cell piece of the adjacent cell piece, and the other section is welded to the front of the other cell piece. In order to facilitate the welding operation of the solder strip connected to the back of the cell piece, the solder strip section connected to the back of the cell piece is usually set as a flat solder strip, and in order to increase the light receiving area of the front of the cell piece, the solder strip section connected to the front of the cell piece is usually set as a solder strip with a special shape such as a triangular or circular arc shape. That is to say, each solder strip connected to the cell piece includes two sections of solder strips with different cross-sectional shapes. For example, a triangular solder strip includes a flat section and a triangular section, and the flat section and the triangular section extend alternately to form a triangular solder strip.

[0004] In actual production, the output rate of each solder strip from the solder strip feeding mechanism may be different, and in addition to machine vibration and other reasons, the nodes (the junction between two cross-sectional shapes is called a node) of each solder strip in a group of solder strips may be uneven, thereby affecting the production quality of the cell string.

[0005] Therefore, a new technical solution is needed to adjust the node position of the solder strip so that the nodes of each group of solder strips in the cell string are in a substantially aligned position (i.e., the nodes of each solder strip are within a predetermined range), thereby improving the quality of the cell string. SUMMARY

[0006] The purpose of the present application is to provide an adjusting plate, a solder strip node adjusting device, a solder strip processing device and a method to solve the problem of uneven nodes of the solder strip in the prior art, which affects the production quality of the cell string.

[0019] Preferably, the welding strip node adjustment device further includes a cover plate covering the adjustment plate to prevent the welding strip from detaching from the first guide groove.

[0021] After the adjustment plate moves forward until the nodes between the flat and irregular sections of the multiple welding strips are respectively engaged at the front end of the corresponding second guide groove, the welding strip pressing mechanism presses the multiple welding strips to tension or stretch the pressed welding strips.

[0022] When the welding strip clamping mechanism is in the state of releasing the welding strip and the welding strip traction device pulls the welding strip forward to a preset position, the cutting and clamping device clamps the welding strip and the welding strip cutting device cuts the clamped welding strip.

[0023] According to another aspect of the present invention, a method for processing solder strips is also provided, the method comprising:

[0024] Multiple parallel welding strips are pulled sequentially through the first guide groove and the second guide groove of the adjusting plate; wherein, the adjusting plate is the adjusting plate as described above;

[0028] After the flat section of the welding strip moves to the front end of the second guide groove of the adjustment plate, and the irregular section located at the rear end of the flat section enters the second guide groove, the frame of the welding strip node adjustment device is driven to move the adjustment plate forward so that the nodes of each welding strip located between the flat section and the irregular section are respectively locked at the front end of the corresponding second guide groove, thereby aligning the nodes of the multiple welding strips in the width direction of the welding strip.

[0032] After the welding strip pressing mechanism presses multiple welding strips, the welding strip processing method further includes:

[0033] The frame of the control strip node adjustment device moves backward so that the strip between the strip pressing mechanism and the cutting clamping device is tensioned or stretched;

[0034] After the cutting and clamping device and the welding strip pressing mechanism release the welding strip and pull the welding strip forward a predetermined distance, the cutting and clamping device clamps the welding strip again and then cuts the welding strip.

[0035] Preferably, after the welding strip pressing mechanism presses multiple welding strips, the welding strip processing method further includes:

[0037] or,

[0038] The tension clamping device located behind the welding strip node adjustment device is controlled to clamp the welding strip and move it backward, so that the welding strip between the welding strip node adjustment device and the tension clamping device is stretched.

[0039] or,

[0040] The tension clamping device located behind the welding strip node adjustment device is controlled to clamp the welding strip. When the welding strip pressing mechanism releases the welding strip, the welding strip traction device is controlled to move forward so that the welding strip between the welding strip traction device and the tension clamping device is stretched to a preset length.

[0041] or,

[0042] The frame of the welding strip node adjustment device is controlled to move backward so that the welding strip between the welding strip pressing mechanism and the cutting clamping device is tensioned, so that the nodes of the welding strip at the front end of the second guide groove are aligned in the width direction of the welding strip. The cutting clamping device is controlled to release, and the welding strip traction device is controlled to pull the welding strip forward to a preset position so that the welding strip between the welding strip pressing mechanism and the welding strip traction device is stretched to a preset length.

Furthermore, "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0058] This invention provides an adjustment plate for adjusting the weld strip nodes, such as... Figure 1 and Figure 2 As shown, the adjustment plate 2 includes an adjustment plate body. The adjustment plate body is provided with a first guide portion 21 near the rear end and a second guide portion 22 near the front end. The first guide portion 21 is provided with a plurality of parallel first guide grooves 211, and the second guide portion 22 is provided with a plurality of parallel second guide grooves 221. The first guide grooves 211 and the second guide grooves 221 both extend in the front-back direction, and the first guide grooves 211 and the second guide grooves 221 correspond one-to-one.

[0059] The welding strip includes staggered flat segments and irregularly shaped segments. The width of the first guide groove 211 is greater than the width of the flat segment, and the width of the second guide groove 221 is less than the width of the flat segment but greater than the width of the irregularly shaped segment. The irregularly shaped segment can be a triangular cross-section or a circular arc cross-section, usually a triangular cross-section.

[0060] When multiple parallel solder strips are positioned within the first guide groove 211, with the flat section of the solder strip located at the front end of the second guide groove 221 and the irregularly shaped section at the rear end of the flat section entering the second guide groove 221, since the width of the second guide groove 221 is smaller than the width of the flat section, the forward movement of the adjusting plate allows the node of each solder strip located between the flat section and the irregularly shaped section to be engaged at the front end of its corresponding second guide groove 221. Here, "forward" refers to the direction from the rear end of the adjusting plate towards the front end.

[0061] The adjustment plate 2 provided by the present invention can move forward so that the nodes of multiple welding strips located between the flat section and the irregular section are respectively locked at the front end of the second guide groove 221, thereby aligning the nodes of multiple welding strip segments in the width direction (i.e., the positions of the predetermined nodes of multiple welding strips in the length direction of the welding strip are within a predetermined range). In this way, when cutting the welding strips, the nodes of the cut multiple welding strip segments are aligned, thereby improving the production quality of the battery string formed by stacking and connecting the welding strip segments and the battery cells.

[0062] In a preferred embodiment, the second guide portion 22 of the adjustment plate 2 is configured to have an inclined surface that rises upward in a direction from back to front, and the second guide groove 221 is disposed on the inclined surface.

[0063] As the welding strip moves forward along the first guide groove 211, when the flat section of the welding strip moves towards the second guide groove 221 after passing through the first guide groove 211, since the width of the flat section is greater than the width of the second guide groove 221, the flat section will rise along the inclined surface of the second guide section 22 without entering the second guide groove 221. When the flat section moves forward to the front end of the second guide groove 221, the subsequent irregular section moves into the second guide groove 221 following the flat section. Then the welding strip stops moving. At this time, the adjustment plate 2 can be driven to move forward until the nodes of each welding strip are respectively stuck at the front end of the corresponding second guide groove 221.

[0064] In this embodiment, preferably, such as Figure 2 As shown, the rear end of the first guide groove 211 has a first notch 212 that expands outward in a rearward direction, and the solder strip can easily enter the first guide groove 211 through the first notch 212.

[0065] Preferably, the front end of the second guide groove 221 is provided with a second notch 222 that expands outward in an upward direction. When the flat section of the welding strip moves forward to the front end of the second guide groove 221, the irregular section that follows can easily enter the second guide groove 221 through the second notch 222.

[0066] According to another aspect of the present invention, a solder strip node adjustment device is also provided, such as... Figure 3 As shown, the welding strip node adjustment device 100 includes a frame 1, a transverse movement mechanism, a welding strip pressing mechanism, and an adjustment plate 2 as described above; wherein,

[0067] The lateral movement mechanism is configured to drive the frame 1 to move in the front-to-back direction;

[0068] The adjusting plate 2 and the welding strip pressing mechanism are mounted on the frame 1. The side of the adjusting plate 2 with the first guide groove 211 and the second guide groove 221 faces upward, and the welding strip pressing mechanism is located at the front end of the adjusting plate 2.

[0069] After the adjustment plate 2 moves forward until the nodes between the flat and irregular sections of the multiple welding strips are respectively locked at the front end of the second guide groove 221, the welding strip pressing mechanism presses the multiple welding strips.

[0070] In this embodiment, the welding strip pressing mechanism specifically includes a mounting frame 4 mounted on the frame 1, a plurality of parallel pressing heads 8 mounted on the mounting frame 4, and a driving mechanism for driving the mounting frame 4 to move up and down, wherein each pressing head 8 corresponds to a second guide groove 221. The driving mechanism is preferably a cylinder 5 mounted on the frame 1, which presses the corresponding welding strip through the pressing heads 8 when the cylinder 5 drives the mounting frame 4 to move downward.

[0071] Preferably, the mounting frame 4 is provided with guide posts 6 that can move up and down relative to the mounting frame 4 and are respectively provided with one of the pressure heads 8. Each pressure head 8 is installed at the lower end of the guide post 6. The welding strip pressing mechanism also includes a spring 7 sleeved on the guide post 6 and located between the mounting frame 4 and the pressure head 8.

[0072] As the pressure head 8 moves downwards to press onto the welding strip, the reverse force of the welding strip on the pressure head 8 causes the guide post 6 to rise relative to the mounting bracket 4, while the spring 7 located between the mounting bracket 4 and the pressure head 8 applies a downward elastic force to the pressure head 8, thereby causing the pressure head 8 to elastically press onto the welding strip.

[0073] Furthermore, the frame 1 includes an upper frame 11 and a base 12. The cylinder body of the cylinder 5 is mounted on the upper frame 11, and a support platform for carrying the welding strip is formed on the base 12. The pressure head 8 presses the welding strip tightly onto the support platform of the base 12.

[0074] In this embodiment, preferably, the welding strip node adjustment device 100 further includes a cover plate 3 covering the adjustment plate 2 to prevent the welding strip from detaching from the first guide groove 211.

[0075] When the transverse mechanism drives the frame 1 to move forward with the adjustment plate 2 so that the nodes of multiple welding strips are aligned at the front end of the second guide groove 221, the cylinder 5 drives the mounting frame 4 to move down, and multiple pressure heads 8 press the welding strips respectively. At this time, the transverse mechanism can drive the frame 1 to move with the welding strip pressing mechanism to tension or stretch the welding strips.

[0076] The specific processing procedure for the welding strip using the welding strip node adjustment device 100 is described below with reference to the welding strip processing equipment and welding strip processing method.

[0077] According to another aspect of the present invention, a solder strip processing apparatus is also provided, such as... Figure 4 As shown, the welding strip processing equipment includes, in a direction from back to front, the welding strip node adjustment device 100, the cutting and clamping device 200, the welding strip cutting device 300, and the welding strip traction device 500, as described above; wherein Figure 5 This is a schematic diagram of the welding strip processing equipment viewed from the side. Figures 6-8 This is a top view schematic diagram of the welding strip processing equipment under different working conditions.

[0078] After the welding strip node adjustment device 100 controls the adjustment plate 2 to move forward (to the right as shown in the figure) until the nodes between the flat sections and irregular sections of multiple welding strips are respectively locked at the front end of the corresponding second guide groove 221, the welding strip pressing mechanism presses multiple welding strips to tension or stretch the pressed welding strips.

[0079] When the welding strip clamping mechanism releases the welding strip and the welding strip traction device 500 pulls the welding strip forward to a preset position, the cutting and clamping device 200 clamps the welding strip, and the welding strip cutting device 300 cuts the welding strip.

[0080] In one embodiment, before the welding strip node adjustment device 100 adjusts the welding strip node, the cutting and clamping device 200 clamps the welding strip. After the adjustment plate 2 moves forward until the nodes between the flat and irregular sections of multiple welding strips are respectively locked at the front end of the second guide groove 221 and the welding strip pressing mechanism presses the welding strip, the welding strip located between the welding strip pressing mechanism and the cutting and clamping device 200 is in a bending device. At this time, the frame 1 of the welding strip node adjustment device 100 can be driven to move backward so that the welding strip between the welding strip pressing mechanism and the cutting and clamping device 200 is tensioned or stretched (i.e., the welding strip is stretched to a certain length). The stretched welding strip can be used to connect two adjacent battery strings after cutting. That is, the stretched welding strip segment is used as the first welding strip of a battery string and the last welding strip of a battery string during production. The welding strip segment connecting two adjacent battery strings is longer than the welding strip segment in the middle of a battery string.

[0081] After the cutting and clamping device 200 and the welding strip pressing mechanism release the welding strip, the welding strip traction device 500 pulls the welding strip forward to a preset position, the cutting and clamping device 200 clamps the welding strip again, and the welding strip cutting device 300 cuts the welding strip.

[0082] In another embodiment, after the welding strip is pressed by the welding strip pressing mechanism, the welding strip traction device 500 can be controlled to pull the welding strip forward to a preset position, so that the welding strip between the welding strip pressing mechanism and the welding strip traction device is stretched to a preset length. Then the welding strip is clamped by the cutting and clamping device 200, and the welding strip cutting device 300 cuts the welding strip. The cut and stretched welding strip segment can be used to connect two adjacent battery strings.

[0083] In another embodiment, after the welding strip pressing mechanism presses the welding strip, the frame 1 of the welding strip node adjustment device 100 is controlled to move backward, so that the welding strip between the welding strip pressing mechanism and the cutting and clamping device 200 is tensioned. At this time, the nodes of multiple welding strips at the front end of the second guide groove 221 of the adjustment plate 2 are aligned in the width direction of the welding strip. The cutting and clamping device 200 is released, and the welding strip traction device is controlled to pull the welding strip forward to a preset position, so that the welding strip between the welding strip pressing mechanism and the welding strip traction device is stretched to a preset length. Then, the cutting and clamping device 200 is controlled to clamp the welding strip, and the welding strip cutting device 300 cuts the welding strip. The cut welding strip is a stretched welding strip segment, which can be used to connect two adjacent battery strings.

[0084] In another implementation, such as Figure 4As shown, the welding strip processing equipment may further include a tension clamping device 400, which is located on the side of the welding strip node adjusting device 100 opposite to the cutting clamping device 200 (i.e., the tension clamping device 400 is located behind the welding strip node adjusting device 100). After the welding strip pressing mechanism clamps multiple welding strips, controlling the tension clamping device 400 located behind the welding strip node adjusting device 100 to clamp the welding strips and move them backward can stretch the welding strip between the welding strip node adjusting device 100 and the tension clamping device 400.

[0085] Alternatively, the tension clamping device 400 located behind the welding strip node adjustment device 100 can be controlled to clamp the welding strip. With the welding strip clamping mechanism releasing the welding strip, the welding strip traction device 500 can be controlled to move forward so that the welding strip between the welding strip traction device 500 and the tension clamping device 400 is stretched, thereby enabling the cutting of an extended welding strip segment for connecting two adjacent battery strings.

[0086] The welding strip processing equipment may also include a node detection device 600. Before the welding strip is pulled past the welding strip node adjustment device 100 and the welding strip node adjustment device 100 adjusts the welding strip node, the node detection device 600 detects whether the welding strip node is within a predetermined range. If the welding strip node is not within the predetermined range, the welding strip can be manually adjusted, and then the welding strip node adjustment device 100 is used to adjust the alignment of the welding strip node.

[0087] The present invention also provides a method for processing solder strips, the method comprising:

[0088] Multiple parallel welding strips are pulled sequentially through the first guide groove 211 and the second guide groove 221 of the adjustment plate 2; wherein, the adjustment plate 2 is the adjustment plate as described above;

[0089] When the flat section of the welding strip is located at the front end of the second guide groove 221, and the irregular section located at the rear end of the flat section enters the second guide groove 221, the adjustment plate 2 is driven to move forward so that the node of each welding strip located between the flat section and the irregular section is respectively locked at the front end of the corresponding second guide groove 221, thereby aligning the nodes of the multiple welding strips in the width direction of the welding strip.

[0090] The present invention also provides a method for processing solder strips, the method comprising:

[0091] Multiple parallel welding strips are pulled from back to front through the welding strip node adjustment device 100 as described above, and each welding strip moves along the first guide groove 211 of the adjustment plate 2 of the welding strip node adjustment device 100.

[0092] After the flat section of the welding strip moves to the front end of the second guide groove 221 of the adjustment plate, and the irregular section located at the rear end of the flat section enters the second guide groove 221, the frame 1 of the welding strip node adjustment device 100 is driven to move forward with the adjustment plate 2 so that the nodes of each welding strip located between the flat section and the irregular section are respectively locked at the front end of the corresponding second guide groove, thereby aligning the nodes of the multiple welding strips in the width direction of the welding strip.

[0093] The welding strip pressing mechanism is controlled to press multiple welding strips.

[0094] In one embodiment, after the flat segment of the solder strip moves to the front end of the second guide groove 221 of the adjustment plate 2, and the irregular segment located at the rear end of the flat segment enters the second guide groove 221, the solder strip processing method further includes:

[0095] The cutting and clamping device 200, located in front of the welding strip node adjustment device, is controlled to clamp the welding strip;

[0096] After the welding strip pressing mechanism presses multiple welding strips, the welding strip processing method further includes:

[0097] The frame 1 of the control strip node adjustment device 100 is moved backward so that the strip between the strip pressing mechanism and the cutting clamping device 200 is tensioned or stretched.

[0098] After the cutting and clamping device 200 and the welding strip pressing mechanism release the welding strip and pull the welding strip forward a predetermined distance, the cutting and clamping device 200 clamps the welding strip again and then cuts the welding strip.

[0099] When cutting normal solder strip segments (i.e., solder strip segments that are not stretched), the solder strip between the solder strip pressing mechanism and the cutting clamping device 200 is simply tensioned. When cutting stretched solder strip segments (solder strip segments used to connect two adjacent battery strings), the frame 1 can be moved further back after the solder strip is tensioned, thereby stretching the solder strip between the solder strip pressing mechanism and the cutting clamping device 200.

[0100] Other methods of stretching the solder strip can also be used to obtain the stretched solder strip segments used to connect two adjacent battery strings.

[0101] In another embodiment, after the welding strip pressing mechanism presses multiple welding strips, the welding strip processing method further includes:

[0102] The welding strip traction device 500 is controlled to pull the welding strip forward to a preset position, so that the welding strip between the welding strip pressing mechanism and the welding strip traction device 500 is stretched to a preset length;

[0103] or,

[0104] The tension clamping device 400 located behind the welding strip node adjustment device 100 is controlled to clamp the welding strip and move it backward, so that the welding strip between the welding strip node adjustment device 100 and the tension clamping device 400 is stretched.

[0105] or,

[0106] The tension clamping device 400 located behind the welding strip node adjustment device 100 is controlled to clamp the welding strip. When the welding strip pressing mechanism releases the welding strip, the welding strip traction device 500 is controlled to move forward so that the welding strip between the welding strip traction device 500 and the tension clamping device 400 is stretched.

[0107] or,

[0108] The frame 1 of the control strip node adjustment device 100 is moved backward, so that the strip between the strip pressing mechanism and the cutting clamping device 200 is tensioned. The nodes of multiple strips at the front end of the second guide groove 221 are aligned in the width direction of the strip. The cutting clamping device 200 is released, and the strip traction device 500 is controlled to pull the strip forward to a preset position, so that the strip between the strip pressing mechanism and the strip traction device 500 is stretched to a preset length. The cutting clamping device 200 is controlled to clamp the strip, and the strip cutting device 300 cuts the strip. The stretched strip segment after cutting can be used to connect two adjacent battery strings.

[0109] The solder strip processing method provided by this invention can be implemented using the solder strip processing equipment described above. The following will refer to... Figures 6-8 A detailed description of a solder strip processing method in one embodiment is provided.

[0110] Multiple parallel welding strips are pulled from back to front (from left to right in the figure) through the tension clamping device 400, the welding strip node adjustment device 100 and the cutting clamping device 200; wherein each welding strip moves along the first guide groove 211 of the adjustment plate 2 of the welding strip node adjustment device 100.

[0111] like Figure 6 As shown, after the predetermined flat section D1 of each welding strip moves to the front end of the second guide groove 221 of the adjustment plate 200, and the irregular section D2 located at the rear end of the flat section D1 enters the second guide groove 221, the welding strip is clamped by the cutting and clamping device 200 in front of the welding strip node adjustment device 100. At this time, the frame 1 of the welding strip node adjustment device 100 is in position A.

[0112] like Figure 7As shown, the frame 1 that drives the welding strip node adjustment device 100 moves forward with the adjustment plate 2 to position B. At this time, the nodes of each welding strip located between the flat section and the irregular section are respectively locked at the front end of the corresponding second guide groove 221, and the nodes of multiple welding strips are aligned in the width direction of the welding strip.

[0113] The welding strip pressing mechanism is controlled to press multiple welding strips, at which time the welding strip located between the welding strip pressing mechanism and the cutting and clamping mechanism 200 is in a bent state;

[0114] like Figure 8 As shown, the frame 1 of the control strip node adjustment device 100 moves backward to position C, and the strip between the strip pressing mechanism and the cutting clamping device 200 is tensioned;

[0115] Then, the cutting and clamping device 200 and the welding strip pressing mechanism release the welding strip, and the welding strip is pulled forward a predetermined distance by the welding strip traction device. Then, the cutting and clamping device 200 clamps the welding strip again, and then the welding strip cutting device 300 cuts the welding strip.

[0116] In the nth adjustment, the node of the welding strip is stuck at the front end of the second guide groove 221 and the welding strip pressing mechanism presses the welding strip. At this time, the cutting clamping device 200 is in the state of releasing the welding strip. The welding strip traction device used to pull the welding strip stretches the welding strip, so that the welding strip between the welding strip pressing mechanism and the welding strip traction device is stretched to a certain length. The welding strip pressing mechanism releases the welding strip, and the welding strip traction device pulls the welding strip forward by a preset distance. Then, the cutting clamping device 200 clamps the welding strip and the welding strip cutting device 300 cuts the welding strip. The obtained welding strip segment is a welding strip segment of a predetermined length that has been stretched.
