Description

Technical Field

[0001] This utility model relates to the field of string welding equipment, and in particular to a welding strip pushing and guiding mechanism. Background Technology

[0002] String welding machines are important equipment in the photovoltaic module production process. Welding strips are used to connect cells together. In the process of stringing several cells together, the string welding machine needs a traction device to clamp several welding strips and place them in the corresponding positions on the cells. The traction device is also used to straighten the welding strips.

[0003] Existing string welding machines use a guide mechanism installed before the traction device. The traction device clamps one end of the welding strip and pulls the traction end of the welding strip from the welding strip cutting station a predetermined distance and through the guide mechanism to guide the welding strip, thereby improving the accuracy of welding the welding strip.

[0004] However, with the current method of guiding the welding strip, the welding strip is difficult to accurately pass through the guiding component of the guiding mechanism during the process of straightening the welding strip by the traction device, which makes the welding strip prone to deviation.

[0005] Therefore, this application aims to provide a welding strip pushing and guiding mechanism to solve the technical problems in the prior art. Utility Model Content

[0006] To address the problem that existing welding strip guiding mechanisms often fail to accurately place the welding strip into the corresponding guide groove during the traction process, leading to easy deviation of the welding strip, this application provides a welding strip pushing and guiding mechanism.

[0007] The welding strip lifting and guiding mechanism provided in this application adopts the following technical solution:

[0008] A welding strip pushing and guiding mechanism, including

[0009] A guide plate, the upper surface of which has an opening forming several guide grooves.

[0010] Several guide blocks are located on one side of the guide plate. Each guide block has a guide groove on its upper surface, and each guide groove communicates with a specific guide slot.

[0011] A chuck plate, slidably mounted on a guide plate, is used to open or close the guide groove.

[0012] A driving device for driving the chuck plate to slide.

[0013] Optionally, the clamp plate is slidably connected with a plurality of baffles, the baffles having at least a first state and a second state. When the baffle is in the first state, the baffle completely covers the guide groove, and when the baffle is in the second state, the guide groove is completely exposed.

[0014] Optionally, the guide plate has a through groove for the baffle plate to be inserted and slid.

[0015] Optionally, the opening of the guide groove near the guide block is smaller than the opening of the guide groove away from the guide block.

[0016] Optionally, the guide groove is at the same height as the bottom surface of the guide channel.

[0017] Optionally, it also includes a limiting mechanism, which includes a limiting plate and a limiting bolt. The limiting plate is connected to the clamping plate, and the limiting bolt is connected to the guide plate. The end of the limiting bolt abuts against the side wall of the limiting plate.

[0018] Optionally, the driving device includes a first slide rail, a first cylinder, and a cylinder mounting base. The first cylinder is disposed at the bottom of the chuck plate, the cylinder mounting base is fixed to the guide plate, the output shaft of the first cylinder is connected to the chuck plate for transmission, and the first slide rail is disposed between the guide plate and the chuck plate.

[0019] Optionally, it also includes a lifting base plate, on which a lifting device is provided, the lifting device being located at the bottom of the clamp plate.

[0020] Optionally, the lifting device includes a second slide rail and a second cylinder. The output shaft of the second cylinder is connected to the guide plate. The second slide rail is used to drive the guide plate and the clamping plate to move up and down under the drive of the second cylinder.

[0021] Optionally, the lifting base plate is provided with a vertical plate, the second slide rail is provided on the vertical plate, and both the second slide rail and the second cylinder are vertically arranged.

[0022] In summary, this application includes at least the following beneficial effects:

[0023] 1. The top opening of the guide plate forms a guide groove. The welding strip falls into the guide groove from the top and then enters the guide groove, making it easier for the welding strip to enter the corresponding guide groove, thus improving the accuracy and success rate of the guide plate in guiding the welding strip.

[0024] 2. After the welding strip enters the guide groove, the baffle plate covers the guide groove to limit and guide the welding strip. During the process of the traction device pulling the welding strip forward a predetermined distance, the baffle plate and the guide groove guide the welding strip entering the guide groove, so that the welding strip is not easy to deviate.

[0035] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0036] Reference Figure 1 and Figure 2The welding strip lifting and guiding mechanism includes a lifting base plate 14, a guide plate 1, a clamping plate 15, and a driving device. The lifting base plate 14 is equipped with a vertical plate 13 and a lifting device for driving the guide plate 1 and the clamping plate 15 to move vertically up and down. The upper surface of the guide plate 1 is open and has several guide grooves 2. Several guide blocks 3 are provided on one side of the guide plate 1. Guide grooves 4 are formed on the upper surface of the guide blocks 3. The guide grooves 4 correspond one-to-one with and communicate with the guide grooves 2. The opening of the guide groove 2 near the guide block 3 is smaller than the opening of the guide groove 2 away from the guide block 3. (Refer to...) Figure 2 As shown, there is a height difference between guide plate 1 and guide block 3. Specifically, the height of guide block 3 is lower than that of guide plate 1. The bottom surface of guide groove 2 is at the same height as the bottom surface of guide groove 4, that is, the bottom surface of guide groove 2 and the bottom surface of guide groove 4 are both at the same level. This allows the welding strip to fall into guide groove 2 first and then into guide groove 4, making the welding strip fall into the guide groove more smoothly and accurately.

[0037] The chuck plate 15 is disposed at the bottom of the guide plate 1 and slides relative to the guide plate 1. Several baffle plates 5 are connected to one side of the chuck plate 15. The guide plate 1 has a through groove for the baffle plates 5 to be inserted and slide. The driving device is used to drive the chuck plate 15 to slide. The chuck plate 15 drives several baffle plates 5 to slide simultaneously, so that the baffle plates 5 have at least a first state and a second state. When the baffle plate 5 is in the first state, the baffle plate 5 completely covers the guide groove 4. When the baffle plate 5 is in the second state, the guide groove 4 is completely exposed. By forming a guide groove 2 through the top opening of the guide plate 1, with one end of the guide groove 2 having a larger opening and the other end having a smaller opening, when the traction device clamps several welding strips over the lifting device and applies a pulling force, the welding strips located at the lifting device are more likely to fall into the guide groove 2. Since the opening of the guide groove 2 near the guide block 3 is smaller, it further limits the welding strip, allowing the welding strip to enter the guide groove 4 more accurately. It should be noted that when the baffle plate 5 completely covers the guide groove 4, the baffle plate 5 and the guide groove 4 only limit the welding strip vertically, and do not clamp the welding strip. During the process of the traction device pulling the welding strip, the welding strip located in the guide groove 4 can still move along its length direction. Compared with ordinary welding strip lifting mechanisms, the welding strip in this application is less likely to deviate.

[0038] Reference Figure 1 and Figure 3The welding strip pushing and guiding mechanism also includes a limiting mechanism, which includes a limiting plate 9 and a limiting bolt 10. The length direction of the limiting bolt 10 is set along the X-axis, and the limiting bolt 10 is set at the bottom of the guide plate 1. The limiting plate 9 is fixed to the bottom of the chuck plate 15. The limiting bolt 10 is located on one side of the chuck plate 15 and limits the limiting plate 9. When the baffle plate 5 is in the second state, the side wall of the limiting plate 9 abuts against the end of the limiting bolt 10. The driving device includes a first slide rail 6, a first cylinder 7, and a cylinder fixing seat 8 for mounting the first cylinder 7. The first slide rail 6 is set between the guide plate 1 and the chuck plate 15 and is used to guide the chuck plate 15 under the drive of the first cylinder 7, so that the chuck plate 15 slides along the X-axis direction.

[0039] The cylinder mounting base 8 is fixed to the bottom of the guide plate 1. The first cylinder 7 is set along the X-axis direction. The output shaft of the first cylinder 7 is connected to the bottom of the limiting plate 9. Since the limiting plate 9 is fixed to the bottom of the chuck plate 15, during the operation of the first cylinder 7, the first cylinder 7 drives the limiting plate 9 to move, and the limiting plate 9 drives the chuck plate 15 to move, thereby opening or closing the guide groove 4.

[0040] Reference Figure 1 and Figure 3 The lifting device includes a second slide rail 11 and a second cylinder 12. The second cylinder 12 is mounted on the lifting base plate 14 along the Z-axis, and its output shaft is connected to the bottom of the guide plate 1. In this application, two upright plates 13 are provided, symmetrically arranged on the upper surface of the lifting base plate 14. One end of each upright plate 13 is fixed to the lifting base plate 14, and the other end is fixed to the bottom of the guide plate 1. Two second slide rails 11 are provided on the two upright plates 13 respectively, and are used to drive the guide plate 1 and the clamping plate 15 to move up and down under the drive of the second cylinder 12. With this setup, before the traction device grips the traction end of the welding strip, the lifting device first lowers the guide plate 1 and the clamping plate 15. As the traction device grips the traction end of the welding strip and leads it out a predetermined distance, the lifting device controls the guide plate 1 and the clamping plate 15 to rise. At this time, the welding strip falls into the corresponding guide groove 2 in sequence and finally enters the guide groove 4. Under the action of the drive device, the baffle plate 5 closes each guide groove 4, thereby guiding the welding strip. On the one hand, it completes the guidance of the welding strip. On the other hand, through the upper opening of the guide plate 1 and the baffle plate 5 working in conjunction with the guide groove 4, the welding strip can more easily enter the predetermined guide component, reducing the possibility of welding strip deviation and improving the accuracy and success rate of welding strips in the string welding machine.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
