Description

Technical Field

[0001] The present application relates to the field of battery production technology, and in particular to a welding ribbon processing device. Background Art

[0002] Photovoltaic cell strings are typically made by stacking conductive ribbons and cells, then connecting them in series. When producing cell strings on photovoltaic cell string production equipment, a ribbon traction clamp is typically used to clamp the end of the ribbon, which is then pulled onto a stringing conveyor. The ribbon is then stacked with cells from a cell loading device and placed onto the stringing conveyor. The stringing conveyor then transports the stacked ribbons and cells to a stringing device, which then connects the ribbons and cells in series to form a cell string.

[0003] However, as the solder ribbons are becoming increasingly thinner, they are difficult to lay accurately and to stack directly with the battery cells for string soldering. Therefore, when laying the ribbons, a ribbon pressing device is often placed on the ribbons to press the ribbons against the battery cells. The general process is as follows: a ribbon pulling device clamps the first free end of the ribbon and pulls it out. Because the ribbon is relatively soft, the unclamped portion of the ribbon droops. The ribbon pressing device presses the drooping portion of the ribbon against the battery cell below it, and then the pulling device releases the ribbon. The welding conveyor device transports the ribbons, battery cells, and ribbon pressing device to the stringing device to complete the battery stringing.

[0004] However, in the prior art, the first free end of the welding ribbon is used for clamping by the welding ribbon pulling device, and the welding ribbon pressing device cannot complete the compression of the end welding ribbon, resulting in waste of the end welding ribbon. Utility Model Content

[0005] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides a welding ribbon processing device that solves the problem in the prior art that the first free end of the welding ribbon is used for clamping by the welding ribbon pulling device, and the welding ribbon pressing device cannot complete the compression of the first free end of the welding ribbon.

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

[0007] In a first aspect, the present application provides a ribbon processing device, which includes a moving module, a ribbon pulling device, a ribbon pressing device, and a conveying device.

[0008] The mobile module includes a translation device and a lifting device. The lifting device is installed on the translation device, and the welding ribbon traction device is installed on the lifting device. The mobile module drives the welding ribbon traction device to move up and down, so as to drive the welding ribbon traction device to place the welding ribbon on the conveying device.

[0009] The welding ribbon pulling device includes a driving mechanism and a clamping mechanism. The clamping mechanism is provided with an extension section for clamping the welding ribbon. The driving mechanism is configured to drive the extension section to clamp and release the welding ribbon to be processed.

[0010] The welding strip pressing device includes a frame and a pressing member group, each pressing member group includes a first pressing pin and at least one second pressing pin spaced apart along the length direction of the welding strip to be processed, the first pressing pin is elastically mounted on the frame through a first elastic member, and the second pressing pin is elastically mounted on the frame through a second elastic member;

[0011] When applying pressure, the extension section clamps the first free end of the solder strip to be processed, the corresponding first pressing needle presses on a pair of extension sections, and the second pressing needle presses on the subsequent part of the solder strip to be processed;

[0012] When the extension section is withdrawn from under the first pressing needle, the first elastic member rebounds to drive the first pressing needle to press tightly against the first free end of the solder strip to be processed.

[0013] The present application sets an extension section so that the welding ribbon traction device clamps the first free end of the welding ribbon to be processed through the extension section, and when the welding ribbon pressing device applies pressure, the first pressure pin of the welding ribbon pressing device can be pressed on the extension section first. When the extension section is withdrawn from under the first pressure pin, the first pressure pin is pressed on the first free end of the welding ribbon to be processed through the rebound of the first elastic member, so that the first free end of the welding ribbon to be processed is pressed on the battery to be processed, avoiding waste caused by the first free end of the welding ribbon to be processed being warped and unable to be welded to the battery to be processed during welding.

[0014] Optionally, the clamping mechanism includes at least one clamping head assembly, each clamping head assembly includes a pair of clamping heads, the extension section includes a pair of clamping portions provided on one side of a first end of the pair of clamping heads, the pair of clamping portions being configured to clamp and release a welding ribbon, and the driving mechanism is in transmission connection with the pair of clamping heads;

[0015] The pressing piece group corresponds to the clamping head assembly one by one.

[0016] Provided is a specific structural mode of a clamping mechanism, which has a simple structure and is easy to use.

[0017] Optionally, when no pressure is applied, the length of the first pressing needle extending from the bottom of the frame is shorter than the length of the second pressing needle extending from the bottom of the frame;

[0018] or,

[0019] The elastic coefficient of the first elastic member is smaller than the elastic coefficient of the second elastic member.

[0020] By controlling the length of the first pressing pin or the elastic coefficient of the first elastic member, after the extension section is withdrawn from under the first pressing pin, the hammering force of the first pressing pin on the first free end of the solder strip to be processed is within an appropriate range due to the rebound of the first elastic member, thereby avoiding the first pressing pin from violently hammering on the first free end of the solder strip to be processed and causing damage to the first free end of the solder strip to be processed or the battery to be processed thereunder.

[0021] Optionally, the frame includes a mounting body, the first pressing needle and the second pressing needle are elastically mounted on the mounting body, and the mounting body is a hollow grid structure.

[0022] The invention provides a specific frame structure with simple structure and convenient use. The weight of the frame is reduced by the hollow grid structure, and heat conduction is better achieved.

[0023] Optionally, the welding strip processing equipment also includes a lifting device, which includes a second mounting frame and two lifting components installed on the second mounting frame. The two lifting components support the two ends of the frame at a high position and drive the frame to descend. Each lifting component includes a lifting drive installed on the second mounting frame, a support plate vertically installed on the driving end of the lifting drive, and a lifting plate horizontally installed on the support plate. The lifting plate is configured to lift the end of the frame.

[0024] By setting up a lifting device, the lifting device drives the first pressing needle to descend and press on the extension section, and the second pressing needle to descend and press on the welding ribbon to be processed before the welding ribbon pressing device presses the welding ribbon to be processed, so as to avoid the first pressing needle and the second pressing needle pressing on the extension section, the welding ribbon to be processed and the battery cell at a faster descending speed, causing damage to them.

[0025] Optionally, the welding ribbon processing equipment further includes a transport device, which includes a robotic arm and a picking component mounted on the robotic arm, and the robotic arm drives the picking component to move to drive the welding ribbon pressing device to move.

[0026] The conveying device is provided to move the pressure welding belt device, so as to realize automatic loading of the pressure welding belt device.

[0027] 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 clamping head.

[0028] By tilting the inclined surface downward in the direction away from the clamping head, the contact area between the pressure welding belt device and the clamping part along the direction of pulling the welding belt is reduced, so that after the pressure welding belt device is pressed on the inclined surfaces of a pair of clamping parts, the clamping part can be withdrawn from under the pressure welding belt device along the direction of pulling the welding belt.

[0029] Optionally, the upper surface of each clamping portion is an inclined surface, and the inclined surface is inclined downward toward the other clamping portion.

[0030] By tilting the inclined surface downward toward the other clamping part, the contact area between the pressure welding belt device and the clamping part in the direction perpendicular to the pulling direction of the welding belt is reduced, so that after the pressure welding belt device is pressed on the inclined surfaces of a pair of clamping parts, the pair of clamping parts can move away from each other to loosen the clamping of the welding belt.

[0032] By providing a third elastic member, a clamping force is provided for a pair of clamping parts to clamp the welding strip, thereby avoiding the need for an external force driving mechanism to provide external force when clamping the welding strip, and also ensuring that a pair of clamping parts can be clamped separately.

[0033] Optionally, the driving mechanism also includes a driving member and a transmission plate arranged at the driving end of the driving member, the driving member is configured to drive the transmission plate to move linearly, and the transmission plate is provided with limiting grooves corresponding to each chuck assembly one by one, and the second ends of a pair of chucks of the chuck assembly are accommodated 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, and the driving member is used to drive the limiting grooves to gradually nest on the second ends of the corresponding pair of chucks so that the pair of clamping parts move away from each other around the rotating axis.

[0034] By arranging a driving member and a transmission plate, the driving member can drive the transmission plate to move linearly, thereby making the limiting groove on the transmission plate cooperate with the clamping head, so that a pair of clamping parts move away from each other around the rotating axis to release the welding strip to be processed.

[0035] Optionally, the widths of the second ends of the pair of clamps are synchronously and gradually reduced toward the limiting groove;

[0036] and / or,

[0049] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] See also Figure 1 and Figure 2 As shown, in some embodiments, the present application provides a welding ribbon processing device, which includes a moving module (not shown), a welding ribbon traction device 1, a welding ribbon pressing device 2 and a conveying device (not shown).

[0051] The mobile module includes a translation device and a lifting device. The lifting device is installed on the translation device, and the welding ribbon pulling device 1 is installed on the lifting device. The mobile module drives the welding ribbon pulling device 1 to move up and down, so as to drive the welding ribbon pulling device 1 to place the welding ribbon on the conveying device.

[0052] The welding ribbon pulling device 1 includes a driving mechanism 11 and a clamping mechanism 12. The clamping mechanism 12 is provided with an extension section 121 for clamping the welding ribbon. The driving mechanism 11 is configured to drive the extension section 121 to clamp and release the welding ribbon to be processed.

[0053] The welding tape pressing device 2 includes a frame 21 and a pressing member group 22. Each pressing member group 22 includes a first pressing pin 221 and at least one second pressing pin 222 arranged at intervals along the length direction of the welding tape to be processed. The first pressing pin 221 is elastically mounted on the frame 21 through a first elastic member, and the second pressing pin 222 is elastically mounted on the frame 21 through a second elastic member.

[0054] When processing a solder ribbon, the drive mechanism 11 first drives the extension 121 to clamp the first free end of the ribbon to be processed. The mobile module then drives the ribbon pulling device 1 to move the front half of the ribbon to be processed onto the processed solar cell (not shown) on the conveyor. The ribbon pressing device 2 is then moved over the front half of the ribbon to be processed, with the first pressing pins 221 of the device pressing the ribbon to press against the corresponding pair of extensions 121, and the second pressing pins 222 pressing against the rear portion of the front half of the ribbon to be processed. Afterwards, the driving mechanism 11 drives the extension section 121 to release the first free end of the soldering ribbon to be processed, and the movable module drives the soldering ribbon traction device 1 to move away from the soldering ribbon pressing device 2 to withdraw the extension section 121 from under the first pressing pin 221, so that the first pressing pin 221 is pressed on the first free end of the soldering ribbon to be processed under the action of the rebound force of the first elastic member, so as to press the first free end of the soldering ribbon to be processed onto the battery to be processed, thereby avoiding the first free end of the soldering ribbon to be processed from 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, and avoiding the waste of the first free end of the soldering ribbon to be processed due to the inability to be welded to the battery cell. After being placed, the first end of the soldering ribbon is also directly pressed by the first pressing pin, which also effectively avoids the warping of the soldering ribbon head.

[0055] In one implementation, the lifting device includes a lifting cylinder, the translation device includes a translation motor module, the lifting cylinder is installed at the driving end of the translation motor module, and the weld ribbon traction device 1 is installed on the driving end of the lifting cylinder. The translation motor module drives the weld ribbon traction device 1 to lift and translate, so as to drive the weld ribbon traction device 1 to place the weld ribbon on the conveying device.

[0056] See also Figures 2 to 4As shown, in some embodiments, the clamping mechanism 12 includes at least one clamping head assembly 122, each of which includes a pair of clamping heads 1221, each of which is a rod-shaped member. The extension section 121 includes a pair of clamping portions 1211 disposed on one side of the first end 1223 of the pair of clamping heads. The clamping portions 1211 are block-shaped members integrally formed with the corresponding clamping heads 1221. The pair of clamping portions 1211 are configured to clamp and release a welding ribbon. The driving mechanism 11 is in transmission connection with the second end 1224 of the pair of clamping heads. The driving mechanism 11 drives the pair of clamping heads 1221 to drive the pair of clamping portions 1211 to clamp or release the welding ribbon to be processed. The clamping member groups 22 correspond one-to-one with the clamping head assemblies 122, so that each clamping member group 22 can respectively clamp a welding ribbon.

[0057] In other embodiments, the chuck 1221 may be a large flat chuck. In this case, the extension is part of the chuck, and is used to hold the solder ribbon. The extension of the flat chuck may be a plate-like structure that gradually becomes thinner from the first free end to the second free end of the solder ribbon.

[0058] See also Figure 1 As shown, in some embodiments, when no pressure is applied, the length of the first pressing pin 221 extending from the bottom of the frame 21 is shorter than the length of the second pressing pin 222 extending from the bottom of the frame 21; or the elastic coefficient of the first elastic member is smaller than the elastic coefficient of the second elastic member. After the extension section 121 is withdrawn from under the first pressing pin 221, the hammering force of the first pressing pin 221 pressing the first free end of the processed solder strip due to the rebound of the first elastic member is within an appropriate range, thereby preventing the first pressing pin 221 from violently hammering the first free end of the processed solder strip and causing damage to the first free end of the processed solder strip or the processed battery below it.

[0059] See also Figure 1 and Figure 5 As shown, in some embodiments, the frame 21 includes a mounting body 211, a first pressing pin 221 and a second pressing pin 222 are elastically mounted on the mounting body 211, the mounting body 211 is generally rectangular, and the mounting body 211 is a hollow grid structure. The first pressing pin 221 and the second pressing pin 222 in each pressing member group 22 are evenly spaced along the width direction of the mounting body 211 and the pressing member groups 22 are evenly spaced along the length direction of the mounting body 211 on the mounting body 211.

[0060] Specifically, pressure pin mounting holes are provided on the grid dividing rods of the mounting body 211. Each pressure pin mounting hole extends vertically from the upper surface of the mounting body 211 to the lower surface of the mounting body 211. Each first pressure pin 221 and second pressure pin 222 is respectively inserted into the corresponding pressure pin mounting hole. The first pressure pin 221 and the second pressure pin 222 are arranged along the length of the welding strip. The first elastic member is sleeved on the corresponding first pressure pin 221, and the lower end of the first elastic member abuts the first step surface of the first pressure pin 221, and the upper end of the first elastic member abuts the lower surface of the mounting body 211. The second elastic member is sleeved on the corresponding second pressure pin 222, and the lower end of the second elastic member abuts on the second step surface of the second pressure pin 222, and the upper end of the second elastic member abuts on the lower surface of the mounting body 211. A locking ring (not shown) is installed on the part of the first pressure pin 221 and the second pressure pin 222 extending out of the upper surface of the mounting body 211. The locking ring is configured to prevent the first pressure pin 221 and the second pressure pin 222 from falling off from the corresponding pressure pin mounting hole.

[0061] Exemplarily, both the first elastic member and the second elastic member are springs.

[0062] See also Figure 5 As shown, in some embodiments, the frame 21 further includes a transported portion 212 located at both ends of the mounting body 211, and an iron block 213 is provided on the upper surface of the transported portion 212. The ribbon processing apparatus further includes a transport device (not shown), the transport device including a robotic arm and a picking component mounted on the robotic arm, the picking component being configured to pick up the pressure-welding ribbon device 2 by attracting the iron block 213 on the transported portion 212 through an electromagnet, and the robotic arm drives the picking component to move to achieve the movement of the pressure-welding ribbon device 2.

[0063] In one implementation, the transport unit may adopt a lifting and translational robotic arm composed of a motor servo module, or a three-axis robot.

[0064] See also Figure 5 As shown, in some embodiments, the welding strip processing equipment also includes a lifting device 3, the lifting device 3 includes a second mounting frame 31 and two lifting components installed on the second mounting frame 31, the two lifting components support the two ends of the frame 21 at a high position and drive the frame 21 to descend, each lifting component includes a lifting drive member 32 installed on the second mounting frame 31, a support plate 33 vertically installed on the driving end of the lifting drive member 32, and a lifting plate 34 horizontally installed on the support plate 33.

[0065] The transport device can move the pressure welding tape device 2 onto the lifting plate 34, so that the lifting plate 34 lifts it through the transported parts 212 at both ends of the installation body 211 of the pressure welding tape device 2. At this time, the welding tape to be processed is located below the pressure welding tape device 2. When the pressure welding tape device 2 needs to be pressed, the lifting drive 32 of the lifting device 3 drives the lifting plate 34 to drive the pressure welding tape device 2 to descend until the first pressing pin 221 presses on the extension section 121 and the second pressing pin 222 presses on the corresponding welding tape to be processed, thereby preventing the transport device from directly transporting the pressure welding tape device 2 at a faster descending speed and a higher descending height and pressing it on the extension section 121 and the welding tape to be processed. For example, the lifting drive 32 is a cylinder.

[0066] See also Figure 4 As shown, in some embodiments, in order to facilitate the withdrawal of a pair of clamping parts 1211 from under the first pressing needle 221, the upper surface of each clamping part 1211 is a slope 123. The slope 123 is arranged to be inclined downward toward the direction of the other clamping part 1211 on the one hand, and inclined downward toward the direction away from the clamping head 1221 on the other hand, so as to reduce the contact area between the clamping part 1211 and the first pressing needle 221 in a direction perpendicular to the pulling direction of the welding ribbon and the contact area between the clamping part 1211 and the first pressing needle 221 in the pulling direction of the welding ribbon, thereby reducing the friction force that needs to be overcome when the pair of clamping parts 1211 are loosened and withdrawn from under the first pressing needle 221 in the pulling direction of the welding ribbon.

[0067] See also Figure 3 and Figure 4 As shown, in some embodiments, each chuck assembly 122 further includes a rotating shaft 1222, and the drive mechanism 11 includes a driving member 111, a transmission plate 112, and a third elastic member (not shown). The middle portion of the pair of chucks 1221 is rotatably connected to the rotating shaft 1222, and the pair of chucks 1221 can rotate around the rotating shaft 1222. The third elastic member is disposed between the rotating shaft 1222 and the second end 1224 of the chuck, and one end of the third elastic member is mounted on one of the chucks 1221 of the pair of chucks 1221, and the other end of the third elastic member is mounted on the other chuck 1221 of the pair of chucks 1221. The third elastic member provides a clamping force to the pair of clamping portions 1211 by spreading the second ends 1224 of the pair of chucks.

[0068] The transmission plate 112 is arranged at the driving end of the driving member 111, and the driving member 111 is configured to drive the transmission plate 112 to move linearly. The transmission plate 112 is provided with a limiting groove 113 corresponding to each clamping head assembly 122. The second end 1224 of a pair of clamps of the clamping head assembly 122 is accommodated in the corresponding limiting groove 113, and the limiting groove 113 and / or the corresponding second end 1224 of at least one clamp gradually changes in width along the moving path of the transmission plate 112.

[0069] When the welding strip needs to be clamped, the driving member 111 does not move. At this time, the transmission plate 112 and the clamping head 1221 move away from each other, and the pair of clamping parts 1211 remain closed under the action of the rebound force of the third elastic member to clamp the first free end of the welding strip to be processed, avoiding the need for an external force driving mechanism 11 to provide external force when clamping the welding strip.

[0070] When the welding ribbon needs to be released, the driving member 111 drives the transmission plate 112 to approach the clamp 1221, so that the limiting groove 113 on the transmission plate 112 gradually nests on the second end 1224 of the corresponding pair of clamps, and then the second ends 1224 of the pair of clamps are relatively close to each other around the rotating shaft 1222, and the first ends 1223 of the pair of clamps are away from each other around the rotating shaft 1222 to drive the pair of clamping parts 1211 to release the welding ribbon to be processed.

[0071] Exemplarily, the third elastic member is a spring, and the driving member 111 is a linear motor, an electric cylinder or a pneumatic cylinder.

[0072] See also Figure 4 As shown, in some embodiments, the widths of the second ends 1224 of a pair of chucks are synchronously and gradually reduced in the direction of the limiting groove 113, so that the second ends 1224 of each chuck are all trapezoidal in design, and the short side of the trapezoid is set on the side facing the transmission plate 112, and the side edges of the trapezoid are in contact with the wall of the limiting groove 113 on the transmission plate 112, so that the transmission plate 112 can drive the corresponding pair of chucks 1221 to approach each other through the limiting groove 113.

[0073] In other embodiments, the width of the limiting groove 113 gradually increases toward the corresponding clamping head 1221. In this case, the limiting groove 113 is designed as a trapezoid, with the long side of the trapezoid located on the side facing the clamping head 1221. The wall of the limiting groove 113 contacts the opposite outer sides of the pair of clamping heads 1221, so that the transmission plate 112 drives the corresponding pair of clamping heads 1221 toward each other through the limiting groove 113.

[0074] See also Figure 2 and Figure 3 As shown, in some embodiments, the welding ribbon traction device 1 also includes a bracket 13 and a guide component 14 arranged on the bracket 13, the driving member 111 is arranged on the bracket 13, and the transmission plate 112 is provided with a guide rod 15 that slides with the guide component 14 to guide the movement of the transmission plate 112.

[0075] The driving member 111 drives the transmission plate 112 to move forward and backward, causing the guide rod 15 to slide relative to the guide component 14 to guide the forward and backward movement of the transmission plate 112, thereby improving the stability of the driving member 111 driving the transmission plate 112 to move forward and backward.

[0076] Specifically, the guide component 14 is a guide sleeve, which is fixedly mounted on the bracket 13 through fasteners. The guide rod 15 slides back and forth in the guide sleeve to guide the forward and backward movement of the transmission plate 112 .

[0077] Of course, in other embodiments, the guide member 14 may also be a guide hole directly opened on the bracket 13 , and the guide rod 15 guides the forward and backward movement of the transmission plate 112 by sliding forward and backward in the guide hole.

[0078] See also Figure 3 As shown, in some embodiments, the welding ribbon pulling device 1 further includes a first mounting bracket 16, which is disposed on the lower side of the transmission plate 112 near the chuck 1221 and is fixedly mounted on the bracket 13. The first mounting bracket 16 is provided with a plurality of mounting holes extending from top to bottom, each of which is provided with a horizontally disposed rotating shaft 1222. A pair of chucks 1221 are disposed in corresponding mounting holes and are rotatably mounted on the first mounting bracket 16 via the rotating shaft 1222, wherein the first ends 1223 of the chucks extend from the bottom of the first mounting bracket 16, and the second ends 1224 of the chucks extend from the top of the first mounting bracket 16.

[0079] In some embodiments, a method for processing a solder ribbon using a solder ribbon processing device includes the following steps:

[0080] The extension section 121 on the clamping mechanism 12 of the ribbon pulling device 1 clamps the first free end of the ribbon to be processed. The moving module (not shown) drives the ribbon pulling device 1 to move to pull the front half of the ribbon to be processed (not shown) onto the battery cell to be processed on the conveyor device.

[0081] The first pressing pin 221 of the pressing welding strip device 2 is pressed against the extension section 121 of the clamping mechanism 12, and the second pressing pin 222 presses the portion of the front half of the welding strip to be processed located subsequent to the first free end onto the battery cell to be processed;

[0082] The extension section 121 of the clamping mechanism 12 releases the solder strip to be processed and withdraws from under the first pressing pin 221. The first elastic member (not shown) rebounds and drives the first pressing pin 221 to press down to press the first free end of the solder strip to be processed onto the battery cell to be processed.

[0083] The above is a detailed description of an embodiment of the present application. However, the content is only a preferred embodiment of the present application and cannot be considered to limit the scope of implementation of the present application. All equivalent changes and improvements made within the scope of the present application should still fall within the scope of the patent application.
