Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, specifically a welding strip spacing and moving mechanism used in a coating equipment. Background Technology

[0002] Photovoltaic cells are semiconductor material components that can convert sunlight into electrical energy. They are one of the key components of solar photovoltaic power generation systems. During production, they need to go through several stages, including welding, stacking, lamination, framing, junction box assembly, curing, and testing. Among these, welding is mostly string welding, which involves welding multiple solder strips to the main grid line on the back of the next photovoltaic cell to obtain a photovoltaic cell array.

[0003] Before welding the solder strips, the cut solder strips need to be spaced so that they can be placed in designated positions on the solar cells. This process involves separating multiple groups of solder strips, each with a different spacing. Existing separation solutions typically require multiple power sources to drive the process based on the number of solder strip groups, which increases costs and makes the equipment too bulky. Utility Model Content

[0004] To address the problems in the prior art, this application provides a welding strip spacing and moving mechanism for a coating equipment, which can drive the welding strip to move at different distances simultaneously.

[0005] The technical solution is as follows: A welding strip spacing moving mechanism for a coating equipment includes a mounting plate, a mounting base on the mounting plate, a transmission rod and a motor on the mounting base, the motor driving the transmission rod to rotate; the transmission rod is provided with driving wheels of different diameters at intervals, each driving wheel is provided with a driven wheel on one side, and they are connected by a transmission belt; a moving plate is connected to the transmission belt.

[0006] Specifically, the driving wheel includes a first driving wheel, a second driving wheel, and a third driving wheel arranged in sequence.

[0007] Specifically, the diameters of the first drive wheel, the second drive wheel, and the third drive wheel gradually decrease.

[0008] Preferably, it further includes a bearing housing disposed on the mounting plate, the bearing housing being provided with a bearing, and the driven wheel being disposed on the bearing housing via the bearing.

[0009] Preferably, the mounting base is provided with a pressure roller assembly, which tensions the transmission belt.

[0010] Preferably, it also includes a clamping plate, the two ends of which are connected to the moving plate and the transmission belt, respectively.

[0011] Preferably, the mounting plate is provided with a guide rail, and the movable plate is connected to the guide rail via a slider.

[0012] Preferably, the mounting plate is provided with a protective cover that shields the transmission belt.

[0013] In summary, by setting multiple driving wheels of different sizes on the transmission rod, and then setting a corresponding number of driven wheels, connecting the driving and driven wheels with transmission belts, and then connecting multiple moving plates to their respective transmission belts, fixing the grippers to the moving plates, and finally having the transmission rod rotated by a motor, the moving plates can be moved. Because the sizes of the driving wheels are different, the rotation speed of each set of transmission belts is also different, thus allowing the moving plates to move different distances simultaneously. Ultimately, this achieves the goal of using a single drive device to drive multiple sets of grippers to separate the welding strips, with each set of welding strips being separated by a different distance. This achieves the above functions while also reducing production costs and the overall size of the equipment. Attached Figure Description

[0016] 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.

[0017] like Figure 1As shown, the system includes a mounting plate 1, a mounting base 2 on the surface of the mounting plate 1, a transmission rod 3 and a motor 14 that drives the transmission rod 3 to rotate on the mounting base 2, and several drive wheels with different diameters spaced apart on the transmission rod 3. Three drive wheels with different diameters are shown in the figure. Three driven wheels 5 are correspondingly located on one side of the drive wheels on the mounting plate 1. A transmission belt 12 connects the drive wheels and their corresponding driven wheels 5. Grippers are mounted on movable plates 9, connecting multiple movable plates 9 to the transmission belt 12. The motor 14 drives the transmission rod 3 to rotate, causing the drive wheels to rotate. Because the diameters of the drive wheels are different, the rotational speeds of each drive wheel are also different, resulting in different speeds on the transmission belt 12. Consequently, the distances traveled by the movable plates 9 in the same amount of time are different, and therefore the distances traveled by the corresponding grippers on the movable plates 9 are also different. This allows a single power source to drive multiple sets of welding strips to move different distances.

[0018] It should be noted that the side of the transmission belt 12 closest to the outside is the outer side, and the other side is the inner side. The connection position between the movable plate 9 and the transmission belt 12 needs to be determined according to actual requirements. When the movable plate 9 is connected to either the outer or inner side of the transmission belt 12 at the same time, the movable plate 9 moves in the same direction at different speeds. When the movable plate 9 is connected to both the inner and outer sides of the transmission belt 12, the movable plate 9 moves in opposite directions at different speeds.

[0019] like Figure 2 As shown, the driving wheels here include a first driving wheel 6, a second driving wheel 7, and a third driving wheel 8 arranged sequentially from bottom to top, with the diameters of the first driving wheel 6, the second driving wheel 7, and the third driving wheel 8 gradually decreasing, resulting in a gradual increase in the rotational speed of the first driving wheel 6, the second driving wheel 7, and the third driving wheel 8. In this embodiment, the diameters of the first driving wheel 6, the second driving wheel 7, and the third driving wheel 8 are 60mm, 40mm, and 20mm, respectively, so the ratio of the first driving wheel 6, the second driving wheel 7, and the third driving wheel 8 is 1:2:3, thereby achieving a single drive source that makes the rotational speed of each driving wheel different. It should be noted that the diameters of the first driving wheel 6, the second driving wheel 7, and the third driving wheel 8 can be set according to actual rotational speed requirements.

[0020] like Figure 2 As shown, a bearing housing 4 is provided on one side of the driving wheel on the mounting plate 1, and a bearing is installed inside the bearing housing 4. The driven wheel 5 is installed on the bearing housing 4. The driving wheel drives the driven wheel 5 to rotate, and through the support of the bearing housing 4 and the function of the bearing, it can rotate smoothly and stably.

[0021] like Figure 2As shown, a pressure roller assembly 15 is provided on the mounting base 2. When the diameter of the drive pulley is large, the distance between the outer and inner sides of the transmission belt 12 will increase, making the transmission belt 12 too loose and affecting its operation. Therefore, a pressure roller assembly 15 is provided at the transmission belt 12 corresponding to the drive pulley with a larger diameter to tension the transmission belt 12 and maintain a suitable tension. As shown in the figure, in this embodiment, a pressure roller assembly 15 is provided at the transmission belt 12 corresponding to the first drive pulley 6 and the second drive pulley 7 to tension the transmission belt 12 corresponding to the first drive pulley 6 and the second drive pulley 7. The pressure roller assembly 15 includes a fixing rod fixed on the mounting base 2, and a bearing is provided on the fixing rod. The bearing contacts the transmission belt 12 to achieve tension. At the same time, the pressure roller assembly 15 is provided at both the outer and inner sides of the transmission belt 12 to tension both the outer and inner sides of the transmission belt 12 simultaneously.

[0022] A clamping plate 11 is provided on the top of the movable plate 9. The clamping plate 11 is used to clamp the transmission belt 12 and fix the movable plate 9 to the transmission belt 12. The clamping plate 11 includes a movable plate and bolts. The movable plate is covered on the transmission belt 12 and locked and fixed by bolt locking.

[0023] A guide rail 10 is also provided on the mounting plate 1, and a slider is provided on the guide rail 10. The back of the movable plate 9 is fixed to the slider, so that the movable plate 9 can move along the guide rail 10.

[0024] A protective cover 13 is installed on the mounting plate 1, which covers all the transmission belts 12 and protects them.

[0025] In use, the grippers are mounted on the corresponding moving plates 9. After the grippers pick up the welding strip, the motor 14 drives the transmission rod 3 to rotate, so that the first drive wheel 6, the second drive wheel 7 and the third drive wheel 8 rotate simultaneously, thereby driving the corresponding transmission belt 12 to rotate. Finally, multiple moving plates 9 are moved at different distances, so that the welding strip picked up by the grippers can be split at different distances.

[0026] Other embodiments of the present invention will readily conceive of by those skilled in the art upon consideration of the specification and practice of the specific embodiments described herein. 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. Furthermore, there may be minor differences in the wording of the names of certain components in different embodiments; these minor differences will not affect the understanding of the present invention by those skilled in the art.
