Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and more specifically, to a welding strip processing device. Background Technology

[0002] Photovoltaic cells are typically composed of multiple cells connected in series by solder ribbons. During assembly, the cells and solder ribbons are arranged in an alternating vertical order. In actual production, if circular cross-section solder ribbons are used to directly weld to the cells, the contact area between the circular cross-section solder ribbon and the cell is relatively small. This results in extremely high pressure on the cell during lamination, which can easily lead to defects such as cracks.

[0003] Therefore, the solder strip needs to be flattened before welding it to the solar cell. Flattening increases the contact area between the solder strip and the solar cell, thereby reducing the pressure on the solar cell during lamination, decreasing the likelihood of cracks and breakage, and ultimately improving the quality and reliability of the photovoltaic cell. Utility Model Content

[0004] The purpose of this invention is to provide a new technical solution for a welding strip processing device.

[0005] According to one aspect of the present invention, a welding strip processing apparatus is provided.

[0006] The welding strip processing device includes:

[0007] Mounting base;

[0008] A drive assembly and a first processing unit, wherein the drive assembly and the first processing unit are respectively disposed on the mounting base;

[0011] Optionally, the second processing unit has a working position and a avoidance position.

[0012] Optionally, the second processing member and the first processing member are arranged opposite each other in the vertical direction, and the movement direction of the moving member is the vertical direction.

[0013] Optionally, the transmission assembly further includes a guide rail and a slider adapted to the guide rail.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0033] This utility model provides a welding strip processing device, which can flatten and shape the welding strip to meet subsequent process requirements.

[0034] like Figure 1 and Figure 2 As shown, the welding strip processing device provided by this utility model includes:

[0035] Mounting base 1;

[0036] The drive assembly 4 and the first processing unit 3 are respectively disposed on the mounting base 1;

[0037] The transmission assembly 5 and the moving part 6 are included. The transmission assembly 5 includes a lead screw 51. One end of the lead screw 51 is connected to the output end of the drive assembly 4, and the other end of the lead screw 51 is connected to the moving part 6 so as to drive the moving part 6 to perform linear motion.

[0038] The second processing element 7 is disposed on the moving element 6, and the second processing element 7 is positioned opposite to the first processing element 3.

[0039] like Figure 1 and Figure 2 As shown, the mounting base 1 is usually made of high-strength metal materials such as aluminum alloy to ensure the stability and durability of the device.

[0040] In one embodiment, the mounting base 1 may include a first portion 11 and a second portion 12, with a space between them for mounting other components and accommodating solder strips. For example, the first portion 11 can be fixed to the worktable of the device, and its upper surface can be bolted to mount the first processing component 3. The second portion 12 can also be bolted to the worktable, maintaining a precise relative position with the first portion 11, so that it can provide a mounting base for other components such as the drive assembly 4.

[0041] In one embodiment, the mounting base 1 can also be configured as an integral structure, which has different spaces for mounting the first processing component 3, the drive assembly 4, and other structures.

[0042] The drive component 4 can be a high-performance power source such as a stepper motor or a servo motor 41, which has advantages such as high control precision and stable operation. The motor can be fixedly mounted on the second part 12 with bolts, with the motor's output shaft facing inwards. The motor housing can be equipped with heat sinks to dissipate the heat generated during long-term operation and ensure the motor's normal operating temperature.

[0043] like Figure 1 and Figure 2 As shown, the transmission assembly 5 includes a lead screw 51, which converts rotary motion into linear motion to drive the moving part 6 in linear motion. Preferably, the lead screw 51 is a ball screw. The ball screw consists of a screw shaft, a nut, and balls. The screw shaft is typically machined with high precision, resulting in a high degree of surface finish and straightness to ensure smooth and accurate transmission. The nut has a ball circulation channel inside, where the balls circulate, thus converting the rotary motion of the screw shaft into the linear motion of the nut.

[0044] like Figure 1 and Figure 2As shown, the bearing 9 can be fixed to the lead screw shaft via the inner ring and connected to the bearing housing 8 via the outer ring, thereby forming a stable support structure that allows the lead screw shaft to rotate around a fixed axis.

[0045] In this way, power is transmitted by utilizing the rolling of balls between the lead screw and the nut. Compared with traditional sliding friction, this rolling friction method greatly reduces friction, thereby reducing energy loss and error accumulation during transmission. At the same time, the lead screw 51 is precision-machined during manufacturing, and its lead accuracy can reach the micrometer level, so as to facilitate precise control of the movement of the second processing component 7.

[0046] like Figure 1 and Figure 2 As shown, one end of the lead screw 51 can be connected to the output end of the drive assembly 4 via a coupling. The coupling can be an elastic coupling, possessing a certain degree of elastic deformation capability, which can compensate for minor coaxiality errors between the output shaft of the drive assembly 4 and the lead screw shaft, thereby reducing vibration and noise during transmission. The other end of the lead screw 51 is mounted on the second part 12 via a bearing housing. The bearing housing contains a high-precision angular contact ball bearing capable of withstanding axial and radial loads on the lead screw shaft, ensuring stable rotation of the lead screw shaft.

[0047] like Figure 1 and Figure 2 As shown, the movable component 6 can be a rectangular or similar rectangular metal plate structure, made of stainless steel, which has high strength and rigidity. The movable component 6 has a threaded hole that mates with the nut of the lead screw 51. The nut is fixed to the movable component 6 by bolts, forming a transmission connection between the lead screw 51 and the movable component 6. When the lead screw 51 rotates under the drive of the drive assembly 4, the nut of the lead screw 51 can drive the movable component 6 to move linearly along the direction of the lead screw axis.

[0048] The second processing component 7 can be designed into a specific shape and structure according to the actual processing requirements of the welding strip. For example, if the welding strip needs to be flattened, the second processing component 7 can be designed as a pressing block with a flat pressing surface; if the welding strip needs to be textured, the second processing component 7 can be designed as a pressing mold with a specific texture.

[0049] The second processing component 7 can be bolted to the lower surface of the movable component 6, allowing it to move linearly with the movable component 6. The second processing component 7 is positioned opposite the first processing component 3 on the first part 11, forming a welding strip channel between them to facilitate the threading of the welding strip. The width of the welding strip channel can be precisely controlled by adjusting the position of the movable component 6, i.e., adjusting the distance between the second processing component 7 and the first processing component 3, thereby meeting the processing requirements of welding strips of different specifications.

[0050] This adjustability makes the device widely applicable, eliminating the need to replace a large number of molds or equipment parts. It can process welding strips of various specifications simply by setting parameters and operating the device.

[0051] When using the welding strip processing device of this utility model, the welding strip to be processed is first placed on the first processing component 3. Then, the drive component 4, such as a motor, is started by the external control system. The motor starts to rotate according to preset parameters, and its rotational motion is transmitted to the lead screw shaft of the lead screw 51 through a coupling. When the lead screw shaft rotates, its nut can drive the moving component 6 and the second processing component 7 to move linearly along the direction of the lead screw shaft, so as to gradually approach the first processing component 3. When the distance between the second processing component 7 and the first processing component 3 reaches the preset welding strip processing distance, the motor stops rotating. At this time, the second processing component 7 and the first processing component 3 cooperate to perform corresponding processing on the welding strip located in the welding strip channel, such as flattening and shaping.

[0052] After processing is completed, the control system controls the motor to rotate in the opposite direction, and the lead screw 51 drives the moving part 6 and the second processing part 7 to move away from the first processing part 3 together, returning to the initial position, so as to facilitate the next welding strip processing operation.

[0053] Therefore, when the drive assembly 4 rotates the lead screw 51, the nut of the lead screw 51 can drive the moving part 6 and the second processing part 7 to move linearly with a precise displacement, thereby accurately controlling the distance between the second processing part 7 and the first processing part 3 on the first part 11. During the welding strip processing, such as when flattening, shaping, or pounding the welding strip, it can ensure that the welding strip is subjected to uniform and precise force, so that the dimensional accuracy of the processed welding strip can meet high standards, thus effectively improving the product qualification rate.

[0054] Compared with traditional mechanical transmission methods, this device has a significantly improved response speed, which can shorten the cycle time of welding strip processing and improve production efficiency.

[0055] Optionally, the second processing member 7 has a working position and a avoidance position. Under the bidirectional drive of the drive assembly 4, the lead screw 51 can drive the second processing member 7 to move closer to or further away from the first processing member 3 and move between the working position and the avoidance position.

[0056] Specifically, under the first drive of the drive assembly 4, its rotational motion is transmitted to the lead screw shaft of the lead screw 51 through the coupling. When the lead screw shaft rotates, its nut can drive the moving part 6 and the second processing part 7 to move linearly along the direction of the lead screw shaft, so as to gradually approach the first processing part 3. When the distance between the second processing part 7 and the first processing part 3 reaches the preset welding strip processing distance, that is, when the second processing part 7 moves to the working position, the drive assembly 4 stops rotating. At this time, the second processing part 7 and the first processing part 3 cooperate to perform corresponding processing on the welding strip located in the welding strip channel, such as flattening, shaping, and crushing.

[0057] After processing is completed, the control system controls the drive component 4 to enter the second drive mode. The lead screw 51 drives the moving part 6 and the second processing part 7 to move away from the first processing part 3 and return to the avoidance position so as to facilitate the next welding strip processing operation.

[0058] Among them, the bidirectional drive of the drive component 4 can be the forward and reverse rotation of the motor.

[0059] Optionally, the second processing member 7 is arranged opposite to the first processing member 3 in a vertical direction, and the movement direction of the moving member 6 is the vertical direction.

[0060] like Figure 1 and Figure 2 As shown, the second processing component 7 and the first processing component 3 are arranged opposite each other in the vertical direction, so that the welding strip channel formed by the two is in the horizontal direction. Under the drive of the drive assembly 4, the lead screw 51 can drive the moving component 6 and the second processing component 7 to move together in the vertical direction to move closer to or away from the first processing component 3, and thus can move between the working position and the avoidance position.

[0061] Furthermore, the moving part 6 and the second processing part 7 are arranged to move together in the vertical direction, so that the second processing part 7 can apply a continuous and uniform processing force to the solder strip located in the solder strip channel, avoiding problems such as solder strip deformation and surface damage caused by uneven processing force, and further improving the quality and consistency of solder strip processing.

[0062] Optionally, the transmission assembly 5 further includes a guide rail 52 and a slider adapted to the guide rail 52. The guide rail 52 is disposed on the mounting base 1, and the slider is disposed on the moving member 6. The extending direction of the guide rail 52 is consistent with the moving direction of the moving member 6.

[0063] like Figure 1 and Figure 2As shown, to ensure the smooth movement of the moving part 6, a linear guide pair can also be provided on the moving part 6. The linear guide pair consists of a guide rail 52 and a slider. The guide rail 52 can be fixed to the second part 12 of the mounting base 1 by bolts, and the slider can be fixed to the moving part 6 by bolts. There is a small gap between the slider and the guide rail 52 to achieve low-friction, high-precision linear motion, while also guiding and supporting the moving part 6 to prevent the moving part 6 from deviating or jamming during movement.

[0064] Thus, the linear guide pair provides stable guidance and support for the movement of the moving part 6. The linear guide pair features high rigidity and a low coefficient of friction, ensuring that the moving part 6 does not deviate or vibrate during linear motion. Even under high-speed motion or long-term continuous operation, the moving part 6 can maintain a stable motion state, thereby ensuring that the relative positional accuracy between the second processing part 7 and the first processing part 3 remains unaffected.

[0065] Optionally, the transmission assembly 5 further includes a timing belt 53, a first wheel 54 and a second wheel 55. The timing belt 53 is sleeved on the outer periphery of the first wheel 54 and the outer periphery of the second wheel 55. The first wheel 54 is connected to the output end of the drive assembly 4, and the second wheel 55 is connected to the lead screw 51.

[0066] like Figure 2 As shown, the arrangement of the timing belt 53, the first wheel 54, and the second wheel 55 can form a driving force transmission path of drive component 4 - first wheel 54 - timing belt 53 - second wheel 55 - lead screw 51 - moving part 6 - second processing part 7. This allows the second processing part 7 to move closer to or further away from the first processing part 3, while also providing a certain impact buffering capacity through the timing belt 53, reducing the impact of impact force on the life of the device.

[0067] Optionally, the transmission assembly 5 further includes a synchronous chain, a third wheel, and a fourth wheel. The synchronous chain is sleeved on the outer periphery of the third wheel and the outer periphery of the fourth wheel, and the third wheel is connected to the output end of the drive assembly 4, while the fourth wheel is connected to the lead screw 51.

[0068] Specifically, the arrangement of the synchronous chain, the third wheel, and the fourth wheel can form a driving force transmission path of drive component 4 - third wheel - synchronous chain - fourth wheel - lead screw 51 - moving part 6 - second processing part 7. This allows the second processing part 7 to move closer to or further away from the first processing part 3 while also providing a certain impact buffer through the synchronous chain, thus reducing the impact of the impact on the lifespan of the device.

[0069] Optionally, the drive assembly 4 includes a servo motor 41, the output of which is connected to the lead screw 51. The servo motor 41 can precisely control the welding strip processing process and the processing force, ensuring the precise controllability of each parameter during the processing, thereby ensuring the uniformity and controllability of the welding strip processing.

[0070] Optionally, the drive assembly 4 further includes a reducer 42, one end of which is connected to the output end of the servo motor 41, and the other end of which is connected to the lead screw 51.

[0071] like Figure 2 As shown, the reducer 42 is placed between the output end of the servo motor 41 and the lead screw 51 to form a driving force transmission path of servo motor 41-reducer 42-lead screw 51, which helps to control the processing of the welding strip and ensures the precise controllability of each parameter during the processing, thereby ensuring the uniformity and controllability of the welding strip processing.

[0072] Optionally, the second processing element 7 and the first processing element 3 are adapted to the shape of the solder strip.

[0073] Specifically, the second processing component 7 and the first processing component 3 are adapted to the shape of the solder strip to facilitate the appropriate processing of the solder strip sandwiched therebetween. For example, if the solder strip needs to be flattened, the second processing component 7 and the first processing component 3 can be designed as pressing blocks with flat pressing surfaces; if the solder strip needs to be textured, the second processing component 7 and the first processing component 3 can be designed as pressing molds with specific textures.

[0074] Optionally, the second processing element 7 has a protrusion 71 on the side near the first processing element 3, the protrusion 71 being able to abut against the welding strip and form a compression.

[0075] like Figure 2 As shown, the protrusion 71 is usually an arc-shaped protrusion, which allows the protrusion 71 to make smooth contact with the solder strip, so as to facilitate the flattening process while avoiding scratching the solder strip, thus helping to ensure the reliability and safety of the process.

[0076] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
