Description

Technical Field

[0001] This utility model belongs to the field of welding strip winding and collection technology, specifically relating to a rotation synchronization and emergency stop anti-slip structure in the welding strip collection process. Background Technology

[0002] Solder ribbon, also known as tin-plated copper ribbon or tin-coated copper ribbon, is divided into busbars and interconnecting strips. It is used to connect the cells of photovoltaic modules and plays an important role in conducting and concentrating electricity.

[0003] During the winding process of welding strip, if an unexpected situation occurs or there is a time when an emergency stop is needed after winding is completed, the take-up reel may continue to rotate due to inertia during the emergency stop, which may cause the welding strip to become loose or tangled.

[0004] Therefore, a rotation synchronization and emergency stop anti-slip structure for the welding strip collection process is proposed. Summary of the Invention

[0005] This invention provides a rotation synchronization and emergency stop anti-slip structure for the welding strip collection process, which aims to solve the problems mentioned above.

[0006] This utility model embodiment provides a rotation synchronization and emergency stop anti-slip structure for welding strip collection, including a side rotating pressure plate and a cylinder, the side rotating pressure plate being located on one side of the cylinder; a transparent polyurethane buffer pad disposed on the outer wall of one side of the side rotating pressure plate; a take-up reel disposed on the outer wall of one side of the transparent polyurethane buffer pad; a cylinder side pressure plate fixed to the output end of the cylinder; an inner support hole penetrating through and opened at the center of the outer wall of one side of the take-up reel; a support column disposed at the center of the outer wall of one side of the side rotating pressure plate, one end of the support column being embedded inside the inner support hole; a ball bearing rollingly embedded in the outer wall of the support column; and a motor drive shaft disposed at the center of the outer wall of the other side of the side rotating pressure plate, the motor drive shaft being fixedly connected to the output end of an external servo motor.

[0007] Furthermore, an infrared transmitter is embedded on the outer side of one side of the take-up reel near the outer side of the inner support hole, an arc plate is provided on one side of the outer wall of the side rotating pressure plate, an infrared receiver is embedded on one side of the outer wall of the arc plate, and a detection groove is formed on the horizontal side of one side of the outer wall of the side rotating pressure plate near the arc plate.

[0008] Furthermore, two retaining rings are symmetrically arranged on the outer wall of the take-up reel.

[0009] Furthermore, a positioning head is provided at the center of the outer wall on the side of the cylinder side pressure plate away from the cylinder.

[0010] Furthermore, the axial centers of the positioning head, the inner support hole, and the support column are on the same horizontal axis;

[0011] By adopting the above technical solution, it is ensured that the positioning head and support column can be inserted into the inner support hole, thereby achieving horizontal positioning.

[0012] Furthermore, the axial motion trajectory of the infrared emitter is the same as the circumferential curvature of the arc plate;

[0013] By adopting the above technical solution, it is ensured that the infrared transmitter moves synchronously in a circular motion when the take-up reel rotates, so that the infrared rays emitted by the infrared transmitter can be received by the infrared receiver set in a circle.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes a transparent polyurethane buffer pad placed between the side rotating pressure plate and the take-up reel. Under clamping force, the transparent polyurethane buffer pad is compressed, and its elastic deformation generates positive pressure on the contact surface between the take-up reel and the rotating pressure plate. The compressed transparent polyurethane buffer pad increases the friction coefficient of the contact surface, forming sufficient static friction to resist the tangential force during rotation. The elastic properties of the transparent polyurethane buffer pad absorb part of the rotational inertia, reducing impact load. The increased friction effectively prevents the take-up reel from continuing to rotate due to inertia, avoiding loosening or tangling of the welding strip. This effectively solves the problems of rotation synchronization and emergency stop anti-slip during the welding strip collection process.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Reference Figure 1-5 This utility model embodiment proposes a rotation synchronization and emergency stop anti-slip structure for the welding strip collection process, including a side rotating pressure plate 1 and a cylinder 5. A transparent polyurethane buffer pad 2 is provided on one outer wall of the side rotating pressure plate 1. A take-up reel 3 is provided on the outer wall of the transparent polyurethane buffer pad 2 away from the side rotating pressure plate 1. Two retaining rings 4 are symmetrically arranged on the outer wall of the take-up reel 3. The retaining rings 4 can limit the welding strip and prevent the welding strip from falling off the take-up reel 3. The cylinder 5 is fixedly connected to a cylinder side pressure plate 6 through its output end. A cylinder side pressure plate 6 is provided at the center of the outer wall away from the cylinder 5. The device has a positioning head 7, and a through inner support hole 8 is provided at the center of one side outer wall of the take-up reel 3. A support column 9 is provided at the center of one side outer wall of the side rotating pressure plate 1. The axes of the positioning head 7, the inner support hole 8 and the support column 9 are on the same horizontal axis, ensuring that the positioning head 7 and the support column 9 can be inserted into the inner support hole 8, thereby achieving horizontal positioning. A rolling ball 10 is embedded on the outer wall of the support column 9 near the inner side of the inner support hole 8. A motor drive shaft 15 is provided at the center of the other side outer wall of the side rotating pressure plate 1. The motor drive shaft 15 is fixedly connected to the output end of an external servo motor.

[0026] An infrared transmitter 11 is embedded on one outer wall of the take-up reel 3 near the outer side of the inner support hole 8. An arc plate 12 is provided on one outer wall of the side rotating pressure plate 1. The axial movement trajectory of the infrared transmitter 11 is the same as the circumferential curvature of the arc plate 12, ensuring that the infrared transmitter 11 moves synchronously in a circular motion when the take-up reel 3 rotates. This allows the infrared rays emitted by the infrared transmitter 11 to be received by the circumferentially arranged infrared receivers 14. Several infrared receivers 14 are embedded on one outer wall of the arc plate 12. The infrared receivers 14 are axially spaced equally on one outer wall of the arc plate 12. The infrared transmitter 11 and the infrared receivers 14 are powered by independent batteries and are electrically connected to independent processors and wireless signals. A detection groove 13 is provided on one outer wall of the side rotating pressure plate 1 near the horizontal side of the arc plate 12 to facilitate the passage of infrared rays.

[0027] The specific implementation method is as follows: an external servo motor drives the motor drive shaft 15 and the side rotating pressure plate 1 to rotate through the output end on one side. With the connection of the transparent polyurethane buffer pad 2 and the support of the support column 9, the take-up reel 3 rotates synchronously and begins to wind and collect the welding strip.

[0028] When an emergency stop is required, the control cylinder 5 drives the cylinder side pressure plate 6 to move horizontally through its output end on one side. The cylinder side pressure plate 6 performs a retraction action, tightly clamping the take-up reel 3. The transparent polyurethane buffer pad 2 is compressed under the clamping force. Its elastic deformation causes the contact surface between the take-up reel 3 and the side rotating pressure plate 1 to generate positive pressure. The compressed transparent polyurethane buffer pad 2 increases the friction coefficient of the contact surface, forming sufficient static friction to resist the tangential force during rotation.

[0029] When the take-up reel 3 has collected enough welding strip, the external servo motor quickly stops rotating. The elastic properties of the transparent polyurethane buffer pad 2 absorb part of the rotational inertia, reducing the impact load. The increased friction effectively prevents the take-up reel 3 from continuing to rotate due to inertia, avoiding the welding strip from becoming loose or tangled.

[0030] When the welding strip winding operation is restarted, the transparent polyurethane buffer pad 2 is in a deformed state, and misalignment occurs between the side rotating pressure plate 1 and the take-up reel 3. At this time, the misalignment angle between the side rotating pressure plate 1 and the take-up reel 3 is determined based on which infrared receiver 14 on the side rotating pressure plate 1 receives the infrared light emitted by the infrared transmitter 11 on the take-up reel 3. Then, the external servo motor is first controlled to drive the side rotating pressure plate 1 to rotate, and the deformation state of the transparent polyurethane buffer pad 2 between the side rotating pressure plate 1 and the take-up reel 3 is gradually relieved. When the side rotating pressure plate 1 and the take-up reel 3 are in the forward position, the cylinder 5 is then controlled to control the cylinder side pressure plate 6 to move away from the take-up reel 3, so that the take-up reel 3 winds and collects the welding strip, effectively preventing the take-up reel 3 from rotating in the opposite direction due to the deformation and reset capability of the transparent polyurethane buffer pad 2, which would cause the welding strip to become loose.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
