Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a welding strip node adjustment device, welding strip processing equipment and welding strip processing method. Background Art

[0002] The cell string welding process is an important process in the production of solar panels, which uses welding ribbons to weld the cells into cell strings.

[0003] In the current string welding process, one section of the welding ribbon is usually welded to the back of one of the adjacent cells, and the other section is welded to the front of the other cell. In order to facilitate the welding operation of the welding ribbon connected to the back of the cell, the welding ribbon section connected to the back of the cell is usually set as a flat welding ribbon, and in order to increase the light receiving area of ​​the front of the cell, the welding ribbon section connected to the front of the cell is usually set as a triangular or arc-shaped welding ribbon. In other words, each welding ribbon connecting the cell includes two sections of welding ribbon with different cross-sectional shapes. For example, a triangular welding ribbon includes a flat section and a triangular section, and the flat section and the triangular section extend alternately to form a triangular welding ribbon.

[0004] In actual production, the rate at which the ribbon feeding mechanism outputs each ribbon may be different. Coupled with machine vibration and other reasons, the nodes (the junction between two cross-sectional shapes is called a node) of each ribbon in a group of ribbons may be uneven, thus affecting the production quality of the battery string.

[0005] To this end, it is necessary to provide a new technical solution to adjust the node position of the welding ribbon so that the nodes of each group of welding ribbons in the battery string are in a basically aligned position (that is, the nodes of each welding ribbon are within a preset range), thereby improving the quality of the battery string.

[0069] The present invention provides a welding strip node adjustment device, such as Figure 1-Figure 3 As shown, the welding strip node adjustment device 100 includes a connecting plate 5 and a driving mechanism for driving the connecting plate 5 to move, and also includes a plurality of mounting frames 3 and a spring 4 arranged between each mounting frame 3 and the connecting plate 5, and each mounting frame 3 is provided with a node clamping block 1 and a clamping mechanism 2;

[0070] Each of the mounting frames 3 is configured to correspond to one of the plurality of parallel welding strips, each of the welding strips comprises a flat section and a shaped section arranged alternately, and the node clamping block is configured to be clamped at a node between the flat section and the shaped section;

[0071] When the driving mechanism drives the connecting plate 5 to move in the length direction of the welding strip, the connecting plate 5 elastically drives the mounting frame 3 to move through the spring 4. After the node clamp 1 on each mounting frame 3 moves to be clamped at a node of the corresponding welding strip, the clamping mechanism 2 clamps the corresponding welding strip, and then moves at least part of the mounting frame 3 in the length direction of the welding strip so that the node clamp 1 on multiple mounting frames 3 corresponding to the welding strips are aligned in the width direction of the welding strip. In the process of moving the mounting frame 3 with the clamping mechanism 2, the welding strip clamped by the clamping mechanism 2 is stretched.

[0072] In the process of producing battery strings using special-shaped welding ribbons, the welding ribbon node adjustment device provided by the present invention can adjust the node alignment of the welding ribbon by node positioning and stretching, so that the nodes of multiple parallel welding ribbons located between the special-shaped sections and the flat sections are aligned in the width direction of the welding ribbon (the "alignment" mentioned in this application means that the positions of multiple nodes in the length direction of the welding ribbon are within a predetermined range), thereby improving the production quality of the battery string formed by stacking and connecting the welding ribbons and battery cells.

[0073] In one embodiment of the present invention, Figure 1The welding strip node adjustment device 100 shown in the figure has a node block 1 and a clamping mechanism 2 (one connecting plate 5 corresponds to multiple mounting frames 3) arranged on the mounting frame 3, and a spring 4 is arranged between each mounting frame 3 and the connecting plate 5, respectively. The driving mechanism connected to the connecting plate 5 for driving the connecting plate 5 to move is a driving motor 7 and a lead screw connected to the driving motor 7, and a nut matching the lead screw is arranged on the connecting plate 5, and the connecting plate 5 is driven to move linearly by the rotation of the lead screw. Of course, the driving mechanism for driving the connecting plate 5 to move can also be a cylinder.

[0074] When the driving mechanism drives the connecting plate 5 to move toward the mounting frame 3, the spring 4 between the connecting plate 5 and the mounting frame 3 is compressed, and the spring 4 pushes the mounting frame 3 to move through the elastic force, and the mounting frame 3 drives the node clamp 1 to move until it is clamped at the node of the welding strip.

[0075] Among them, the node clamp block 1 can be set to be stuck on the node when moving from the special-shaped section of the welding strip toward the flat section, limited by the width of the flat section; or, the node clamp block 1 is set to be stuck on the node when moving from the flat section of the welding strip toward the special-shaped section, limited by the height of the special-shaped section.

[0076] In this embodiment, the driving mechanism is also configured to drive the connecting plate 5 to continue to move after the node clamping block 1 is clamped at the node of the welding strip and the clamping mechanism 2 clamps the welding strip so that the spring 4 is compressed between the connecting plate 5 and the mounting frame 3, and when there is a preset distance between each mounting frame 3 and the connecting plate 5, multiple node clamping blocks 1 are aligned in the width direction of the welding strip.

[0077] Preferably, a limiting component 6 for limiting the compression degree of the spring 4 is provided between the mounting frame 3 and the connecting plate 5, and the preset distance between the mounting frame 3 and the connecting plate 5 is limited by the limiting component 6. The limiting component 6 may be a long strip structure installed on the connecting plate 5, or a block structure installed on the connecting plate 5 corresponding to each mounting frame 3, or a block structure installed on each mounting frame 3. When the driving mechanism drives the connecting plate 5 to move and the distance between the connecting plate 5 and the mounting frame 3 is limited by the limiting component 6, the spring 4 cannot be further compressed. At this time, multiple mounting frames 3 are aligned, and the clamping mechanism 2 on the mounting frame 3 pulls the welding strip, so that the welding strip nodes on the mounting frame 3 that are stuck at the node clamping block 1 are aligned.

[0078] In another embodiment of the present invention, Figure 2The welding strip node adjustment device 100 shown in the figure has a node clamp block 1 and a clamping mechanism 2 (one connecting plate 5 corresponds to multiple mounting frames 3) provided on the mounting frame 3, a spring 4 is provided between each mounting frame 3 and the connecting plate 5, and the driving mechanism connected to the connecting plate 5 for driving the connecting plate 5 to move is a first cylinder 8.

[0079] When the first cylinder 8 drives the connecting plate 5 to move toward the mounting frame 3, the spring 4 between the connecting plate 5 and the mounting frame 3 is compressed, and the spring 4 pushes the mounting frame 3 to move through the elastic force, and the mounting frame 3 drives the node clamp 1 to move until it is clamped at the node of the welding strip.

[0080] Among them, the node clamp block 1 can be set to be stuck on the node when moving from the special-shaped section of the welding strip toward the flat section, limited by the width of the flat section; or, the node clamp block 1 is set to be stuck on the node when moving from the flat section of the welding strip toward the special-shaped section, limited by the height of the special-shaped section.

[0081] In this embodiment, the welding strip node adjustment device 100 also includes a push plate 9 arranged on the side of the mounting frame 3 away from the connecting plate 5 for pushing the mounting frame 3 and a pushing mechanism for driving the push plate 9 to move. The pushing mechanism in this embodiment adopts a second cylinder 10, and of course it can also be driven by a motor.

[0082] After the node clamp block 1 is clamped at the node of the welding strip and the clamping mechanism 2 clamps the welding strip, the pushing mechanism drives the push plate 9 to move, so that the push plate 9 pushes the mounting frame 3 to move toward the connecting plate 5. When there is a preset distance between each mounting frame 3 and the connecting plate 5, multiple node clamp blocks 1 are aligned in the width direction of the welding strip.

[0083] Preferably, a limiting component ( Figure 2 (not shown in the figure), the preset distance between the mounting frame 3 and the connecting plate 5 is limited by the limiting component. When the pushing mechanism drives the push plate 9 to move toward the mounting frame 3, the push plate 9 pushes at least part of the mounting frame 3 to move toward the connecting plate 5, and the spring 4 continues to be compressed. When the distance between each mounting frame 3 and the connecting plate 5 is limited by the limiting component 6, the spring 4 cannot be further compressed. At this time, multiple mounting frames 3 are aligned, and the clamping mechanism 2 on the mounting frame 3 pulls the welding strip, so that the welding strip nodes at the node clamping block 1 on the mounting frame 3 are aligned.

[0084] In yet another embodiment of the present invention, Figure 3In the welding strip node adjustment device 100 shown, a node clamping block 1 and a clamping mechanism 2 are provided on a mounting frame 3 , and a spring 4 is provided between each mounting frame 3 and a connecting plate 5 .

[0085] In this embodiment, the welding strip node adjustment device 100 further includes a driving frame 12, on which a connecting plate 5 located on one side of the mounting frame 3 and a pushing portion 11 located on the other side of the mounting frame 3 are disposed;

[0086] When the driving mechanism drives the driving frame 12 to move in a first direction, the connecting plate 5 drives the mounting frame 3 to move through the spring 4. After the node clamp 1 on the mounting frame 3 moves to be clamped at the welding strip node and the clamping mechanism 2 clamps the welding strip, the driving mechanism drives the driving frame 12 to move in a second direction opposite to the first direction. The pushing portion 11 pushes the mounting frame 3 to move. When the pushing portion 11 is in contact with multiple mounting frames 3, the node clamps 1 on multiple mounting frames 3 are aligned in the width direction of the welding strip.

[0087] The driving mechanism may be a lead screw driven to rotate by the motor 13 and the electrode 13, and the drive frame 12 is driven to move by the lead screw and the nut provided on the drive frame 12. Of course, the driving mechanism may also be a driving cylinder.

[0088] According to another aspect of the present invention, a welding strip processing device is also provided. Figure 4-Figure 15 As shown, the welding strip processing equipment includes the welding strip node adjustment device 100, the cutting and clamping device 200, the welding strip cutting device 300 and the welding strip pulling device (not shown in the figure) as described above, which are arranged in sequence;

[0089] When the cutting and clamping device 200 clamps multiple parallel welding strips so that the welding strips are in a tensioned state, each of the node clamping blocks 1 of the welding strip node adjustment device 100 moves to the node where it is clamped on the welding strip, and the clamping mechanisms 2 corresponding to each of the node clamping blocks 1 clamp the welding strips respectively, driving at least part of the mounting frame 3 of the welding strip node adjustment device 100 to move until the nodes of each welding strip are aligned; after the cutting and clamping device 200 and the welding strip node adjustment device 100 release the welding strip, the welding strip pulling device pulls the welding strip 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.

[0090] Preferably, the clamping mechanism 2 of the welding strip node adjustment device 100 is closer to the cutting clamping device 200 than the node clamping block 1; the clamping mechanism 2 moves away from the cutting clamping device 200 after clamping the welding strip, and the welding strip between the cutting clamping device 200 and the clamping mechanism 2 is stretched.

[0091] Preferably, n number of the welding strip node adjustment devices 100 are arranged at intervals along the extension direction of the welding strip, where n≥2, and the interval between two adjacent welding strip node adjustment devices 100 is the distance of a welding strip segment, where a welding strip segment includes a flat segment and a shaped segment of the welding strip. In this way, the node alignment of n welding strip segments can be adjusted at one time.

[0092] Since the nodes of n weld ribbon segments are adjusted at one time, in order to improve production efficiency, n weld ribbon segments can be cut at one time. To this end, n weld ribbon cutting devices 300 are arranged at intervals along the extension direction of the weld ribbon. After the weld ribbon traction device pulls the weld ribbon to move a distance of at least n weld ribbon segments, the n weld ribbon cutting devices 300 respectively correspond to the weld ribbon segment adjusted by a weld ribbon node adjustment device.

[0093] After the solder strip is processed by the solder strip processing equipment provided by the present invention, the solder strip node alignment is adjusted by node positioning and stretching, and then the solder strip is cut to form solder strip segments for stacking with battery cells, which can improve the quality of the battery string formed by connecting the solder strip and the battery cells.

[0094] The welding strip processing equipment provided by the present invention is described in detail below through specific implementation methods.

[0095] First embodiment:

[0096] like Figure 4-Figure 7 As shown, the welding strip processing equipment includes a welding strip node adjustment device 100, a cutting and clamping device 200, a welding strip cutting device 300 and a welding strip pulling device (not shown in the figure), wherein Figure 4 is a side view of the welding strip processing device, Figure 5-Figure 7 It is a top view of the solder strip processing equipment in different working states.

[0097] In this embodiment, Figure 1 The welding strip node adjustment device 100 is shown. The clamping mechanism 2 of the welding strip node adjustment device 100 is closer to the cutting clamping device 200 than the node clamping block 1 .

[0098] The specific process of the solder strip processing device in this embodiment processing the solder strip is as follows:

[0099] Pulling a plurality of parallel welding ribbons D from the welding ribbon providing device, and making the welding ribbons D pass through the welding ribbon node adjusting device 100, the cutting and clamping device 200, and the welding ribbon cutting device 300 in sequence;

[0100] The cutting and clamping device 200 is used to clamp the welding strip D, so that the welding strip D is in a tensioned state;

[0101] The welding strip node adjustment device 100 is used to adjust the nodes of the welding strip D to be aligned in the width direction of the welding strip; specifically, the connecting plate 5 is driven by the driving motor 7 to move in a direction away from the cutting and clamping device 200, and the connecting plate 5 moves from the initial position A to the clamping node position B (reference Figure 4 ), Figure 5 The connecting plate 5 is shown in the initial position A. Figure 6 The figure shows the state where the connecting plate 5 moves to the node position B. At this time, the connecting plate 5 drives the mounting frame 3 to move to the node where the node clamp 1 is clamped at the node of the welding strip D through the elastic force of the spring 4; wherein, the node clamp 1 in this embodiment moves from the flat section D1 of the welding strip D to the special-shaped section D2 of the welding strip, and the cross-section of the special-shaped section D2 is a triangle or an arc or other shapes, and the node clamp 1 is clamped by the height portion of the special-shaped section D2 being higher than the flat section D1.

[0102] After each node clamp block 1 is clamped at the node of the welding strip, the clamping mechanism 2 on the mounting frame 3 clamps the corresponding welding strip D, and the clamping mechanism 2 is clamped at the flat section D1 of the welding strip D;

[0103] The connecting plate 5 is driven to continue to move away from the cutting and clamping device 200. During this process, the connecting plate 5 pushes at least a portion of the mounting frame 3 to move. When the clamping mechanism 2 moves away from the cutting and clamping device 200 along with the mounting frame 3, the welding strip clamped between the cutting and clamping device 200 and the clamping mechanism 2 is stretched. The welding strip stretched between the cutting and clamping device 200 and the clamping mechanism 2 generally includes a flat section D1 and a special-shaped section D2.

[0104] When the connecting plate 5 moves to the node alignment position C, Figure 7 In the state shown, the connecting plate 5 moves until the spring 4 can no longer be compressed, that is, the distance between the connecting plate 5 and the mounting frame 3 is limited by the limiting component 6. At this time, the mounting frames 3 corresponding to the welding strips are aligned in the width direction of the welding strips, and the node blocks 1 are aligned, so that the nodes of the welding strips are aligned.

[0105] Then, the welding strip D clamped by the cutting and clamping device 200 and the welding strip node adjustment device 100 is released, and the welding strip pulling device is used to pull the welding strip D to move a predetermined length, so that the welding strip extends out of the welding strip cutting device 300 by a certain distance;

[0106] The cutting and clamping device 200 is used again to clamp the welding strip and the welding strip cutting device 300 is used to cut the welding strip to obtain welding strip segments;

[0107] Then, the steps of the cutting and clamping device 200 clamping the welding strip and the welding strip node adjusting device 100 adjusting the nodes of the welding strip D are repeated.

[0108] In this embodiment, the solder joint processing device may further include a stretching clamping device 400, which is located on the side of the solder strip node adjustment device 100 away from the cutting clamping device 200. When the solder strip node adjustment device 100 adjusts the solder strip node, the cutting clamping device 200 and the stretching clamping device 400 may clamp the solder strip respectively, so that the solder strip node adjustment device 100 adjusts the node of the solder strip tensioned between the cutting clamping device 200 and the stretching clamping device 400.

[0109] Second implementation method:

[0110] like Figure 8-Figure 11 As shown, the welding strip processing equipment includes a welding strip node adjustment device 100, a cutting and clamping device 200, a welding strip cutting device 300 and a welding strip pulling device (not shown in the figure), wherein Figure 8 is a side view of the welding strip processing device, Figure 9-11 It is a top view of the solder strip processing equipment in different working states.

[0111] In this embodiment, Figure 2 The welding strip node adjustment device 100 is shown. The clamping mechanism 2 of the welding strip node adjustment device 100 is closer to the cutting clamping device 200 than the node clamping block 1 .

[0112] The specific process of the solder strip processing equipment to process the solder strip is as follows:

[0113] Pulling a plurality of parallel welding ribbons D from the welding ribbon providing device, and making the welding ribbons D pass through the welding ribbon node adjusting device 100, the cutting and clamping device 200, and the welding ribbon cutting device 300 in sequence;

[0114] The cutting and clamping device 200 is used to clamp the welding strip D, so that the welding strip D is in a tensioned state;

[0115] The welding strip node adjustment device 100 is used to adjust the nodes of the welding strip D to be aligned in the width direction of the welding strip; specifically, the first cylinder 8 drives the connecting plate 5 to move toward the cutting and clamping device 200, and the connecting plate 5 moves from the initial position A to the clamping node position B (reference Figure 8 ), Fig. 9 The connecting plate 5 is shown in the initial position A. Fig.10 The figure shows the state where the connecting plate 5 moves to the node position B. At this time, the connecting plate 5 drives the mounting frame 3 to move to the node where the node clamp 1 is clamped at the node of the welding strip D through the elastic force of the spring 4; wherein, the node clamp 1 in this embodiment moves from the irregular segment D2 of the welding strip D to the flat segment D1 of the welding strip, and the node clamp 1 is clamped by the width of the flat segment D1 in the width direction being greater than the irregular segment D2.

[0116] After each node clamp block 1 is clamped at the welding strip node, the clamping mechanism 2 on the mounting frame 3 clamps the corresponding welding strip;

[0117] The push plate 9 is driven by the second cylinder 10 to move from the initial position C (the push plate 9 is located on the side of the mounting frame 3 away from the connecting plate 5) away from the cutting and clamping device 200. During this process, the push plate 9 pushes at least part of the mounting frame 3 to move. When the clamping mechanism 2 moves away from the cutting and clamping device 200 with the mounting frame 3, the clamped welding strip is stretched;

[0118] When the push plate 9 moves to the node alignment position E, as shown in Fig.11 In the state shown, the push plate 9 moves until the spring 4 can no longer be compressed, that is, the distance between the connecting plate 5 and the mounting bracket 3 is limited by the limiting component. At this time, the mounting brackets 3 corresponding to the welding strips are aligned in the width direction of the welding strips, and the node blocks 1 are aligned, so that the nodes of the welding strips are aligned.

[0119] Then, the welding strip D clamped by the cutting and clamping device 200 and the welding strip node adjustment device 100 is released, and the welding strip pulling device is used to pull the welding strip D to move a predetermined length, so that the welding strip extends out of the welding strip cutting device 300 by a certain distance;

[0120] The cutting and clamping device 200 is used again to clamp the welding strip and the welding strip cutting device 300 is used to cut the welding strip to obtain welding strip segments;

[0121] Then, the steps of the cutting and clamping device 200 clamping the welding strip and the welding strip node adjusting device 100 adjusting the nodes of the welding strip D are repeated.

[0122] In this embodiment, the solder joint processing device may also include a stretching clamping device 400, which is located on the side of the solder strip node adjustment device 100 away from the cutting clamping device 200. When the solder strip node adjustment device 100 adjusts the solder strip node, the cutting clamping device 200 and the stretching clamping device 400 may clamp the solder strip respectively, so that the solder strip node adjustment device 100 adjusts the node of the solder strip tensioned between the cutting clamping device 200 and the stretching clamping device 400.

[0123] Those skilled in the art can also understand that the clamping mechanism 2 of the welding strip node adjustment device 100 can also be arranged to move away from the stretching clamping mechanism 400 after clamping the welding strip, so that the welding strip between the stretching clamping mechanism 400 and the clamping mechanism 2 is stretched, thereby aligning the welding strip nodes.

[0124] Implementation

[0125] like Figure 12-Figure 15As shown, the welding strip processing equipment includes a welding strip node adjustment device 100, a cutting and clamping device 200, a welding strip cutting device 300 and a welding strip pulling device (not shown in the figure), wherein Fig.12 is a side view of the welding strip processing device, Figure 13-15 It is a top view of the solder strip processing equipment in different working states.

[0126] In this embodiment, Figure 3 The welding strip node adjustment device 100 shown in the figure has three welding strip node adjustment devices 100 arranged at intervals along the length direction of the welding strip, and three groups of welding strip nodes can be adjusted at the same time. Of course, two or more welding strip node adjustment devices 100 can also be arranged. The interval between two adjacent welding strip node adjustment devices 100 is set to be the distance of a welding strip segment, and a welding strip segment includes a flat segment and a special-shaped segment of the welding strip.

[0127] The specific process of the solder strip processing equipment to process the solder strip is as follows:

[0128] Pulling a plurality of parallel welding ribbons D from the welding ribbon supply device, and making the welding ribbons D pass through three welding ribbon node adjustment devices 100, cutting and clamping devices 200 and welding ribbon cutting devices 300 in sequence;

[0129] The cutting and clamping device 200 is used to clamp the welding strip D, so that the welding strip D is in a tensioned state;

[0130] Three welding strip node adjustment devices 100 are used to adjust a group of nodes of the welding strip D to be aligned in the width direction of the welding strip. Specifically, the motor 13 drives the driving frame 12 to move the connecting plate 5 toward the cutting and clamping device 200, and the driving frame 12 moves from the initial position A to the clamping node position B (refer to Fig.12 ), Fig.13 The driving frame 12 is shown in the initial position A. Fig.14 The state in which the driving frame 12 moves to the node position B is shown. At this time, the connecting plate 5 on the driving frame 12 drives the mounting frame 3 to move to the node where the node clamping block 1 is clamped at the node of the welding strip D through the elastic force of the spring 4; wherein, the node clamping block 1 in this embodiment moves from the irregular segment D2 of the welding strip D to the flat segment D1 of the welding strip, and the node clamping block 1 is clamped by the width of the flat segment D1 in the width direction being greater than the irregular segment D2.

[0131] After each node clamping block 1 is clamped at the node of the welding strip, the clamping mechanism 2 on each mounting frame 3 clamps the corresponding welding strip, specifically, clamps it on the flat section D1 of the welding strip;

[0132] The motor 13 of each welding strip node adjustment device 100 drives the driving frame 12 to move from the clamping node position B away from the cutting and clamping device 200. During this process, the pushing portion 11 on each driving frame 12 pushes at least part of the mounting frame 3 to move. When the clamping mechanism 2 moves with the mounting frame 3 away from the cutting and clamping device 200, the clamped welding strip is stretched.

[0133] When the drive frame 12 moves to the node alignment position C, Fig.15 In the state shown, the push portion 11 on the driving frame 12 moves to contact each mounting frame 3, and each mounting frame 3 is aligned in the width direction of the welding strip, so that the nodes of the welding strip are aligned.

[0134] Then, the welding strip D clamped by the cutting and clamping device 200 and the welding strip node adjustment device 100 is released, and the welding strip pulling device is used to pull the welding strip D to move a predetermined length, so that the welding strip extends out of the welding strip cutting device 300 by a certain distance;

[0135] The cutting and clamping device 200 is used again to clamp the welding strip and the welding strip cutting device 300 is used to cut the welding strip to obtain welding strip segments; wherein, the welding strip pulling device can pull the welding strip to move at least three welding strip segments, and three welding strip cutting devices and cutting and clamping devices corresponding to the welding strip cutting devices are provided at intervals, each cutting and clamping device clamps a group of welding strip segments and the corresponding welding strip cutting device cuts a section of welding strip, so that three groups of welding strip segments can be cut at the same time, which can greatly improve production efficiency. Of course, the welding strip pulling device can also be provided to pull three times, and the welding strip cutting device 300 can be provided to cut three times.

[0136] Then, the steps of the cutting and clamping device 200 clamping the welding strip and the welding strip node adjusting device 100 adjusting the nodes of the welding strip D are repeated.

[0137] In this embodiment, the welding strip processing device may also include a stretching clamping device 400, which is located on the side of the welding strip node adjustment device 100 away from the cutting clamping device 200. When the welding strip node adjustment device 100 adjusts the welding strip node, the cutting clamping device 200 and the stretching clamping device 400 can clamp the welding strip respectively, so that the welding strip node adjustment device 100 adjusts the node of the welding strip tensioned between the cutting clamping device 200 and the stretching clamping device 400.
