Description

Technical Field

[0001] This application relates to the technical field of battery production, and particularly to a solder tape traction device and a string welding machine. Background Art

[0002] A photovoltaic cell string is generally formed by stacking and connecting conductive tapes and solar cells. When a photovoltaic cell string production device manufactures a cell string, generally, a chuck of a solder tape traction device clamps the end of a solder tape, pulls the solder tape onto a series connection conveying device, stacks the solder tape together with the solar cells provided by a solar cell feeding device onto the series connection conveying device, the series connection conveying device conveys the stacked solder tape and solar cells to a series connection device, and the series connection device connects the solder tape and the solar cells into a cell string.

[0003] However, since solder tapes are becoming thinner and thinner, it is difficult to accurately lay them, and it is also difficult to directly stack them with solar cells and then complete string welding. Therefore, when laying a solder tape, a solder tape pressing device is often placed on the solder tape to press the solder tape against the solar cell. The general process is as follows: the solder tape traction device clamps the first free end of the solder tape and pulls out the solder tape. Since the solder tape is relatively soft, the unclamped part of the solder tape will sag. The solder tape pressing device presses the sagging part of the solder tape against the solar cell below the solder tape, and then the traction device releases the solder tape. The welding conveying device conveys the solder tape, the solar cell, and the solder tape pressing device to the series connection device to complete cell string connection.

[0004] However, in the prior art, the first free end of the solder tape is used for clamping by the solder tape traction device, and the solder tape pressing device cannot press the end part of the solder tape, resulting in waste of the end part of the solder tape. Summary of the Utility Model

[0005] This application aims to at least solve one of the technical problems existing in the prior art. For this purpose, this application provides a solder tape traction device and a string welding machine, which solve the problem that the solder tape clamped by the solder tape traction device in the prior art cannot be pressed by the solder tape pressing device, resulting in waste of this section of the solder tape.

[0006] The purpose of this application can be achieved through the following technical solutions:

[0007] In a first aspect, this application provides a solder tape traction device, which includes a driving mechanism and at least one chuck assembly. Each chuck assembly includes a pair of chucks and a pair of clamping parts arranged on one side of the first end of the pair of chucks. The pair of clamping parts are configured to be able to clamp and release a solder tape, and the driving end of the driving mechanism is in transmission connection with the second ends of the pair of chucks.

[0008] In this application, a clamping portion is provided on one side of the first end of the collet, so that the solder tape traction device clamps the solder tape through a pair of clamping portions. In this way, when the subsequent solder tape pressing device presses the solder tape, the solder tape pressing device can first press on the upper surface of the pair of clamping portions. After the pair of clamping portions are withdrawn from below the solder tape pressing device, the solder tape pressing device then automatically presses down on the first free end of the solder tape clamped by the pair of clamping portions, so that the first free end of the solder tape is pressed tightly on the battery to be processed, avoiding waste caused by the first free end of the solder tape being unable to be welded to the battery to be processed due to the inability to make close contact with the battery to be processed during welding.

[0009] Optionally, the upper surface of each clamping portion is an inclined surface, and the inclined surface is inclined downward in a direction away from the collet.

[0010] By setting the inclined surface to be inclined downward in a direction away from the collet, the contact area between the solder tape pressing device and the clamping portion in the solder tape traction direction is reduced, facilitating the subsequent withdrawal of the clamping portion from below the solder tape pressing device along the solder tape traction direction after the solder tape pressing device presses on the inclined surfaces of the pair of clamping portions.

[0011] Optionally, the upper surface of each clamping portion is an inclined surface, and the inclined surface is inclined downward in a direction towards the other clamping portion.

[0012] By setting the inclined surface to be inclined downward in a direction towards the other clamping portion, the contact area between the solder tape pressing device and the clamping portion in a direction perpendicular to the solder tape traction direction is reduced, facilitating the mutual separation of the pair of clamping portions to release the clamping of the solder tape after the solder tape pressing device presses on the inclined surfaces of the pair of clamping portions.

[0013] Optionally, each collet assembly further includes a rotating shaft and an elastic member. A pair of collets are rotatably connected to the rotating shaft, the elastic member is disposed between the pair of collets, the elastic member is configured to drive the pair of clamping portions to clamp the solder tape, and the driving mechanism is configured to drive the second ends of the pair of collets to rotate relatively closer to each other around the rotating shaft so that the first ends of the pair of collets drive the pair of clamping portions to move away from each other around the rotating shaft.

[0014] A specific structure of the collet assembly is provided, with a simple structure, enabling the pair of clamping portions to clamp the solder tape by the clamping force provided by the elastic member, avoiding the need for an external force driving mechanism to provide external force when clamping the solder tape, and at the same time ensuring that each of the pair of clamping portions can clamp independently.

[0015] Optionally, the elastic member is disposed between the rotating shaft and the second end of the collet.

[0016] By disposing the elastic member between the rotating shaft and the second end of the collet, the elastic member can provide a clamping force for the pair of clamping portions by spreading apart the second ends of the pair of collets.

[0017] Optionally, the driving mechanism includes a driving member and a transmission plate disposed at the driving end of the driving member. The transmission plate is provided with limiting grooves corresponding to each pair of chucks one by one. The second ends of each pair of chucks are received in the corresponding limiting grooves, and the width of the limiting grooves and / or the second ends of at least one corresponding chuck gradually changes along the moving path of the transmission plate. The driving member is configured to drive the transmission plate to linearly move, so that the limiting grooves gradually nest the second ends of a corresponding pair of chucks to drive the pair of clamping portions away from each other.

[0018] A specific structural manner of the driving mechanism is provided, so that the driving mechanism drives the transmission plate to linearly move through the driving member, and then the limiting grooves on the transmission plate cooperate with the chucks, so that a pair of clamping portions rotate around the rotating shaft to move away from each other to release the solder tape to be processed.

[0019] Optionally, the widths of the second ends of a pair of chucks gradually decrease synchronously in the direction towards the limiting grooves;

[0020] and / or,

[0021] The width of the limiting groove gradually increases in the direction towards the corresponding chuck.

[0022] Two specific cooperation manners between the limiting groove and a pair of chucks are provided, so that the second ends of a pair of chucks can move relative to the limiting groove in the corresponding limiting groove to realize the release of the clamping of the solder tape by a pair of clamping portions.

[0023] Optionally, the solder tape traction device further includes a bracket and a guiding member disposed on the bracket. The driving member is disposed on the bracket, and a guiding rod that is slidably engaged with the guiding member for guiding the movement of the transmission plate is disposed on the transmission plate.

[0024] By disposing the driving member on the bracket, disposing the guiding member on the bracket, and disposing the guiding rod that is slidably engaged with the guiding member on the transmission plate to guide the movement of the transmission plate driven by the driving member, the stability of the movement of the transmission plate is improved.

[0025] Optionally, the solder tape traction device further includes a mounting frame disposed on the bracket. The chuck is rotatably mounted on the mounting frame through a rotating shaft.

[0026] By providing the mounting frame and rotatably mounting the chuck on the mounting frame through the rotating shaft, the installation of the chuck is facilitated.

[0027] In a second aspect, the present application provides a string welding machine. The string welding machine includes the above-mentioned solder tape traction device. The string welding machine further includes a solder tape feeding device, a solder tape pressing device, a battery cell handling device, a conveying device, and a string welding device;

[0028] There are two solder tape traction devices. The two solder tape traction devices alternately traction the solder tape from the solder tape feeding device and place the solder tape on the conveying device. The solder tape pressing device and the solar cell handling device synchronously handle the solder tape pressing device and the solar cell to the conveying device, place the solar cell on the latter half of the solder tape tractioned by the solder tape traction device, and place the solder tape pressing device on the former half of the solder tape tractioned by the solder tape traction device. The edge of the solder tape pressing device close to the solder tape traction device coincides with the clamping part on the solder tape traction device in the horizontal projection plane;

[0029] The solder tape pressing device is a recyclable independent component.

[0030] By using the string welding machine in this application, the solder tape pressing device can first be pressed tightly on a pair of clamping parts of the solder tape traction device. After a pair of clamping parts release the solder tape and withdraw from below the solder tape pressing device, the solder tape pressing device continues to press down to press the end of the solder tape clamped by the clamping parts tightly on the solar cell, making the end of the solder tape in close contact with the solar cell, so as to facilitate subsequent welding of the end of the solder tape to the solar cell, avoiding waste of the end of the solder tape during welding. The alternate operation of the two solder tape traction devices improves the pulling and laying efficiency of the solder tape. Brief Description of the Drawings

Detailed Description of the Embodiment

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0039] In some embodiments, please refer to Figures 1-4 As shown, the present application provides a solder tape traction device 100. The solder tape traction device 100 includes a driving mechanism 1 and at least one chuck assembly 2. Each chuck assembly 2 includes a pair of chucks 21 and a pair of clamping portions 22. Each chuck 21 and the clamping portion 22 correspond one by one. Each clamping portion 22 extends from the first end 23 of the corresponding chuck 21 to one side. The pair of clamping portions 22 are configured to be able to clamp and release a solder tape. The driving end of the driving mechanism 1 is in transmission connection with the second ends 24 of the pair of chucks 21 to drive the pair of clamping portions 22 to clamp and / or loosen the solder tape.

[0040] Specifically, the chuck 21 is a rod-shaped member, and the clamping portion 22 is a block-shaped member integrally formed with the corresponding chuck 21. In the present application, by providing the clamping portion 22 on one side of the first end 23 of the chuck 21, the solder tape traction device 100 clamps the solder tape through the pair of clamping portions 22. When the subsequent solder tape pressing device 200 presses the solder tape, the solder tape pressing device 200 can first press on the upper surface of the pair of clamping portions 22. After the pair of clamping portions 22 release the solder tape and withdraw from below the solder tape pressing device 200 along the solder tape traction direction, the solder tape pressing device 200 then automatically presses down to press the first free end of the solder tape clamped by the pair of clamping portions 22 on the battery cell, so that the first free end of the solder tape is closely attached to the battery cell, avoiding the waste of the first free end of the solder tape due to non-contact and inability to weld with the battery cell in the subsequent process.

[0041] In some embodiments, please refer to Figure 3 As shown, to facilitate the withdrawal of the pair of clamping portions 22 from below the solder tape pressing device 200, the upper surface of each clamping portion 22 is an inclined surface 25. The inclined surface 25 is inclined downward in one direction towards the other clamping portion 22; and is inclined downward in the other direction towards the direction away from the chuck 21, so as to reduce the contact area between the clamping portion 22 and the solder tape pressing device 200 along the direction perpendicular to the solder tape traction direction and the contact area between the clamping portion 22 and the solder tape pressing device 200 along the solder tape traction direction, and reduce the frictional force required for the pair of clamping portions 22 to release and withdraw from below the solder tape pressing device 200 along the solder tape traction direction.

[0042] In some embodiments, please refer to Figure 1 and Figure 3As shown, each chuck assembly 2 further includes a rotating shaft 3 and an elastic member (not shown). The middle parts of a pair of chucks 21 are rotatably connected to the rotating shaft 3, and the pair of chucks 21 can rotate around the rotating shaft 3. The elastic member is arranged between the pair of chucks 21 and is configured to drive a pair of clamping portions 22 to clamp the welding tape. The driving mechanism 1 is configured to drive the second ends 24 of the pair of chucks 21 to relatively approach each other around the rotating shaft 3 so that the first ends 23 of the pair of chucks 21 drive the pair of clamping portions 22 to move away from each other around the rotating shaft 3.

[0043] When it is necessary to clamp the welding tape, the driving mechanism 1 first drives the second ends 24 of the pair of chucks 21 to relatively approach each other around the rotating shaft 3, so that the first ends 23 of the pair of chucks 21 relatively move away from each other around the rotating shaft 3, and further the pair of clamping portions 22 move away from each other. When the first free end of the welding tape is located in the clamping area between the pair of clamping portions 22, the driving mechanism 1 removes the driving force on the pair of clamping portions 22, so that the pair of clamping portions 22 approach each other under the action of the resilience of the elastic member to clamp the first free end of the welding tape and maintain the clamping force on the welding tape.

[0044] In some embodiments, the elastic member is arranged between the rotating shaft 3 and the second end 24 of the chuck 21. Specifically, one end of the elastic member is installed on one of the pair of chucks 21, and the other end of the elastic member is installed on the other chuck 21 of the pair of chucks 21. The elastic member provides a clamping force for the pair of clamping portions 22 by spreading the second ends 24 of the pair of chucks 21.

[0045] Further, a plurality (such as two or three) of elastic members are arranged between the rotating shaft 3 and the second end 24 of the chuck 21 to increase the clamping force provided by the elastic member for the pair of clamping portions 22 and make the pair of clamping portions 22 clamp the welding tape more stably.

[0046] Exemplarily, the elastic member can be a spring.

[0047] In some embodiments, please refer to Figure 1 and Figure 2 As shown, the driving mechanism 1 includes a driving member 11 and a transmission plate 12. The transmission plate 12 is installed at the driving end of the driving member 11. The transmission plate 12 is provided with limiting grooves 13 corresponding to each pair of chucks 21 one by one. The second ends 24 of each pair of chucks 21 are received in the corresponding limiting grooves 13, and the width of the limiting grooves 13 and / or the second ends 24 of the corresponding at least one chuck 21 gradually changes along the moving path of the transmission plate 12. The driving member 11 is configured to drive the transmission plate 12 to linearly move, so that the limiting grooves 13 gradually nest the second ends 24 of the corresponding pair of chucks 21, and further the second ends 24 of the pair of chucks 21 relatively approach each other around the rotating shaft 3, and the first ends 23 of the pair of chucks 21 relatively move away from each other around the rotating shaft 3 to realize that the pair of clamping portions 22 move away from each other to release the clamping on the welding tape.

[0048] Exemplarily, the driving member 11 can be a driving structure such as a linear motor, a cylinder, or an electric cylinder that can linearly drive the transmission plate 12 to approach or move away from the second end 24 of the chuck 21.

[0049] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the widths of the second ends 24 of a pair of chucks 21 gradually decrease synchronously in the direction of the limiting groove 13, so that the second ends 24 of each chuck 21 are trapezoidally designed, and the short sides of the trapezoid are arranged on the side facing the transmission plate 12, and the sides of the trapezoid are in contact with the wall of the limiting groove 13 on the transmission plate 12, which facilitates the transmission plate 12 to drive the corresponding pair of chucks 21 to approach each other through the limiting groove 13.

[0050] In other embodiments, the width of the limiting groove 13 gradually increases in the direction of the corresponding chuck 21. At this time, the limiting groove 13 is trapezoidally designed, and the long side of the trapezoid is arranged on the side facing the chuck 21, and the wall of the limiting groove 13 is in contact with the relative outer sides of a pair of chucks 21, so that the transmission plate 12 drives the corresponding pair of chucks 21 to approach each other through the limiting groove 13.

[0051] In some embodiments, please refer to Figure 1 As shown, the solder tape traction device 100 further includes a bracket 4 and a guiding member 5 provided on the bracket 4. The driving member 11 is provided on the bracket 4, and a guiding rod 6 that is slidably engaged with the guiding member 5 is provided on the transmission plate 12 for guiding the movement of the transmission plate 12.

[0052] The driving member 11 drives the transmission plate 12 to move back and forth, so that the guiding rod 6 slides relative to the guiding member 5 to guide the back and forth movement of the transmission plate 12, thereby improving the stability of the driving member 11 to drive the transmission plate 12 to move back and forth.

[0053] Specifically, the guiding member 5 is a guiding sleeve, and the guiding sleeve is fixedly installed on the bracket 4 through a fastener. The guiding rod 6 slides back and forth in the guiding sleeve to realize guiding the back and forth movement of the transmission plate 12.

[0054] It should be noted that in other embodiments, the guiding member 5 can also be a guiding hole directly formed on the bracket 4, and the guiding rod 6 slides back and forth in the guiding hole to guide the back and forth movement of the transmission plate 12.

[0055] In some embodiments, please refer to Figure 1As shown, the solder tape traction device 100 further includes a mounting frame 7. The mounting frame 7 is arranged on the lower side of the transmission plate 12 near the chuck 21 and is fixedly mounted on the bracket 4. A plurality of mounting holes penetrating from top to bottom are provided on the mounting frame 7, and a horizontally arranged rotating shaft 3 is installed in each mounting hole. A pair of chucks 21 are inserted into the corresponding mounting holes and are rotatably mounted on the mounting frame 7 through the rotating shaft 3. Among them, the first end 23 of the chuck 21 extends out from below the mounting frame 7, and the second end 24 of the chuck 21 extends out from the upper end of the mounting frame 7.

[0056] In some embodiments, the present application further provides a string welding machine. The string welding machine includes the above-mentioned solder tape traction device 100, and the string welding machine further includes a solder tape feeding device (not shown), a solder tape pressing device, a battery cell handling device (not shown), a conveying device (not shown), and a string welding device (not shown).

[0057] There are two solder tape traction devices 100. The two solder tape traction devices 100 alternately traction the solder tape from the solder tape feeding device and place the solder tape on the conveying device. The solder tape pressing device and the battery cell handling device synchronously transport the solder tape pressing device 200 and the battery cell to the conveying device, place the battery cell on the latter half of the solder tape tractioned by the solder tape traction device 100, place the solder tape pressing device 200 on the front half of the solder tape tractioned by the solder tape traction device 100, and the edge of the solder tape pressing device 200 close to the solder tape traction device 100 coincides with the clamping part 22 on the solder tape traction device 100 in the horizontal projection plane.

[0058] Among them, the solder tape pressing device 200 is a recyclable independent component. The solder tape pressing device includes a mounting frame 201 and a row of elastic pressing needles 202 arranged on the mounting frame 201. Each row of pressing needles corresponds to a clamping part 22, and each row of elastic pressing needles is used to press a solder tape.

[0059] By using the string welding machine in the present application, the solder tape pressing device 200 can first press on a pair of clamping parts 22 of the solder tape traction device 100. After a pair of clamping parts 22 release the solder tape and withdraw from below the solder tape pressing device 200, the solder tape pressing device 200 continues to press down to press the end of the solder tape clamped by the clamping parts 22 on the battery cell, so that the end of the solder tape is in close contact with the battery cell, facilitating subsequent welding of the end of the solder tape to the battery cell, avoiding waste of the end of the solder tape during welding, and also realizing direct pressing after the solder tape is placed, avoiding warping of the end of the solder tape.
