Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, specifically a welding strip positioning mechanism. Background Technology

[0002] Solar energy, as a renewable energy source, is abundant, free to use, requires no transportation, and causes no environmental pollution. It has created a new lifestyle for humanity, ushering in an era of energy conservation and pollution reduction. Photovoltaic cells are mainly divided into crystalline silicon (including monocrystalline and polycrystalline cells) and amorphous silicon. In the photovoltaic cell production process, welding rods are needed to connect the cells. Before welding, the welding rods are placed on a platform, and then the cells are placed on the platform for welding.

[0003] After the welding rod is placed on the platform, it will be slightly offset as the suction cup rises. This will change the position of the welding rod and the battery cell, and these changes will affect the subsequent processes. Utility Model Content

[0004] To address the problems in the prior art, this application provides a welding strip positioning mechanism that enables the positioning of tilted welding strips.

[0005] The technical solution is as follows: A welding strip positioning mechanism includes a base plate and a top plate, the base plate and the top plate being arranged parallel to each other and capable of lifting and lowering relative to each other; the base plate is longitudinally spaced with positioning groups, each positioning group including positioning pins arranged laterally spaced along the base plate, the positioning pins in adjacent positioning groups being staggered, the staggered positioning pins forming a positioning channel, and the welding strip being located in the positioning channel; the top plate is provided with through holes corresponding to the positioning pins, the positioning pins passing through the through holes through the top plate.

[0006] Preferably, it includes a lifting device that drives the base plate or the top plate to move up and down.

[0007] Preferably, the top of the positioning pin is provided with a hemispherical surface, and the diameter of the hemispherical surface is 1mm-2mm.

[0008] Preferably, the hemisphere and the locating pin are connected by an inclined plane, the inclination angle of which is 30°-60°.

[0009] Preferably, the width of the positioning channel is the width of the welding rod.

[0010] Preferably, the locating pin extends 2mm-3mm beyond the top plate.

[0011] Preferably, the base plate is provided with a threaded hole, and the bottom outer wall surface of the positioning pin is provided with a thread, and the positioning pin is set in the threaded hole by the thread.

[0012] In summary, by raising and lowering the locating pins, the two ends of the welding electrode are positioned, thereby correcting any tilted electrode and achieving the final positioning effect, facilitating subsequent processing of the electrode. Furthermore, the staggered arrangement of the locating pins effectively reduces the number of pins required without affecting the electrode's contact point, lowering development costs. Additionally, the hemispherical surface at the top of the locating pins, with its curved design, effectively prevents the electrode from being lifted by the pins and failing to fall, further improving the overall smoothness of the mechanism's operation.

[0015] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0016] like Figure 1 As shown, the system includes a base plate 1 and a top plate 2 arranged parallel to each other. Several positioning groups 3 are longitudinally arranged on the base plate 1. The number of positioning groups 3 can be set according to requirements; as shown in the figure, six positioning groups 3 are arranged. Each positioning group 3 consists of several positioning pins 4, which are spaced apart laterally along the base plate 1. The positioning pins 4 in adjacent positioning groups 3 are staggered, as shown... Figure 2 As shown, in the two sets of positioning groups 3 from bottom to top, the positioning pins 4 in the second-to-last group of positioning group 3 are located between the positioning pins 4 in the first-to-last group of positioning group 3. That is, the positioning pins 4 in the second-to-last group of positioning group 3 and the positioning pins 4 in the first-to-last group of positioning group 3 are staggered and do not overlap. A positioning channel is formed between the two staggered positioning pins 4. Figure 2In the diagram, the gap between the first positioning pin 4 in the second-to-last positioning group 3 and the first positioning pin 4 in the penultimate positioning group 3 forms a positioning channel. This pattern continues, and when each positioning group 3 consists of N positioning pins 4, then N positioning channels can be formed. Each positioning group 3 in the diagram consists of 36 positioning pins 4, which can provide positioning for 36 welding rods 5. In this embodiment, through holes are provided on the top plate 2 corresponding to the positions of the positioning pins 4, allowing the positioning pins 4 to pass through the through holes into the top plate 2.

[0017] It should be noted that the staggered arrangement of the locating pins 4 can reduce the number of locating pins 4 arranged longitudinally without affecting the contact position with both sides of the welding rod.

[0018] It should be noted that, as Figure 2 As shown, the positioning is divided into two main groups, upper and lower. Each main group consists of six positioning subgroups 3. The number of positioning subgroups needs to be set according to the length and position of the welding rod 5. When the welding rod 5 is too long and both ends of the welding rod 5 need to be positioned, multiple positioning subgroups are needed. When both ends of the welding rod 5 do not need to be positioned, only one positioning subgroup is needed. When there are many positioning scenarios for the welding rod 5, the number of positioning subgroups needs to be set according to the situation.

[0019] This embodiment also includes a lifting device, not shown in the figure. The lifting device can be a cylinder or a lead screw, or other device capable of linear motion. In this embodiment, a cylinder is selected. The output end of the cylinder is connected to the base plate 1, allowing the cylinder to control the base plate 1 to move up and down, and to control the positioning pin 4 to move back and forth through the top plate 2. Alternatively, the output end of the cylinder is connected to the top plate 2, and the cylinder controls the top plate 2 to move up and down, allowing the positioning pin 4 to move back and forth through the top plate 2. Since the welding rod 5 is placed on the top plate 2, the movement of the top plate 2 will cause the welding rod 5 to move slightly. Therefore, in this embodiment, the solution of moving the base plate 1 is adopted.

[0020] The initial position of the positioning pin 4 is such that its top is below the surface of the top plate 2. The suction cup moves the welding rod 5 onto the top plate 2. The suction cup's installation position is designed and adjusted, and its movement position is also set to prevent significant tilting or displacement of the welding rod 5, allowing it to be transported into the positioning channel. When the head of the welding rod 5 tilts to the left, the cylinder controls the bottom plate 1 to rise, and the positioning pin 4 extends out of the top plate 2. The positioning pin 4 on the left side of the welding rod 5 touches the tilted position of the welding rod 5's head, lifting the welding rod 5 upwards, causing it to fall to the right. Simultaneously, the positioning pin 4 on the right side rises to limit the right side of the welding rod 5. When the positioning pin 4 reaches its endpoint, the tilted welding rod 5 is positioned. Similarly, when the head of the welding rod 5 tilts slightly to the right, the positioning pin 4 also reaches its endpoint, completing the positioning of the tilted welding rod 5. After positioning, the cylinder controls the bottom plate 1 to descend, returning the positioning pin 4 to its initial position.

[0021] To prevent the welding electrode 5 from falling off as it is lifted by the locating pin 4, a hemispherical surface is provided on the top of the locating pin 4. When the welding electrode 5 is lifted, it will fall down along the arc surface. The diameter of the hemispherical surface is set to 1mm, or 1.5mm, or 2mm.

[0022] To further ensure a smoother drop of the welding rod 5, a chamfered bevel is formed at the top of the locating pin 4. This bevel connects to the hemispherical surface, allowing the welding rod 5 to fall along the bevel while simultaneously providing cushioning and slowing its descent to prevent damage. The bevel angle is 30°, but can also be set to 45° or 60°.

[0023] In this embodiment, the width of the positioning channel is set according to the width of the welding rod 5, and is consistent with the width of the welding rod 5 to avoid inaccurate positioning due to being too large, or inability to position due to being too small.

[0024] In this embodiment, the length of the positioning pin 4 extending out of the top plate is set to 2mm, or 2.5mm, or 3mm. This avoids excessive extension time, which would affect overall efficiency, and also avoids incomplete positioning, which could occur.

[0025] To facilitate the disassembly and installation of the positioning pin 4, a threaded hole for installing the positioning pin 4 is provided on the base plate 1, and a corresponding thread is provided on the outer wall surface of the bottom of the positioning pin 4. The threaded connection method facilitates the disassembly and installation of the positioning pin 4.

[0026] In actual use, the suction cup is used to move the welding rod 5 to the positioning channel on the top plate 2. The cylinder controls the bottom plate 1 to rise, and the positioning pin 4 rises to correct and adjust the tilted welding rod 5. After positioning is completed, the cylinder controls the bottom plate 1 to fall, so that the positioning pin 4 can move to the initial position, and the welding rod 5 can proceed to the next processing step.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not described herein.
