Description

Technical Field

[0001] This application relates to the field of photovoltaic welding strip processing technology, and in particular to a welding strip sampling and winding device. Background Technology

[0002] In the photovoltaic module manufacturing process, the solder ribbon serves as the conductive bridge connecting the series-connected solar cells. Its performance parameters (including conductivity, yield strength, and coating uniformity) directly determine the output efficiency and long-term reliability of the photovoltaic module. Therefore, each batch of solder ribbon needs to be sampled and inspected. The winding sampling of the solder ribbon is an important pre-processing step in the sampling inspection, and its sampling quality will significantly affect the accuracy of subsequent test data.

[0003] Currently, the sampling of welding strips mainly relies on manual labor or equipment with low automation. Among these, manual operation is inefficient and the quality is inconsistent, while existing winding machines still require manual operation in key steps such as fixing and disassembling the welding strips, resulting in low efficiency and difficulty in meeting production needs. Utility Model Content

[0004] Based on this, the present invention provides a welding strip sampling and winding device to solve the problem of low efficiency in existing welding strip winding sampling.

[0014] In one embodiment, the gripper includes two clamping plates hinged to the fixed base, the clamping plates having a triggering end near the triggering block and a clamping end away from the triggering block;

[0015] Both of the trigger ends of the two clamping plates have arc-shaped contact surfaces on their sides that are close to each other, and a gap is provided between the two arc-shaped contact surfaces. The trigger block has a wedge-shaped end that can be inserted into the gap at the end facing the clamping claw.

[0016] In one embodiment, the elastic element comprises two springs;

[0017] Each of the clamping plates is provided with a spring between its side away from the other clamping plate and the fixing seat, the spring providing a force to the clamping plate toward the other clamping plate.

[0018] In one embodiment, the winding body includes at least two winding pieces distributed circumferentially along a circumference, and the center of the circumference where each winding piece is located coincides with the rotation center of the rotating disk.

[0019] In one embodiment, the outer surface of the winding piece is an arc-shaped surface, and the outer surfaces of each winding piece are located on the same cylindrical surface.

[0020] In one embodiment, the winding laminations are spaced apart along the circumferential direction, and the intervals between adjacent winding laminations form spacing grooves; and / or,

[0021] The winding lamination is provided with spacing grooves.

[0022] In one embodiment, the clamping assembly is disposed inside each of the winding pieces;

[0023] At least one of the spacer slots constitutes a wire groove, which extends axially from a position on the winding body opposite to the clamping end of the clamping plate to one end of the winding body away from the rotating disk;

[0024] The groove is opposite to the opening of the gripper when the winding body is in the first circumferential position.

[0025] In one embodiment, the solder strip sampling and winding device further includes a wire unwinding mechanism, the wire unwinding mechanism comprising:

[0026] A retraction lever is located on the circumferential outer side of the winding body, with its axis perpendicular to the rotation axis of the winding body. At least one of the spacers forms a slot, which is opposite to the retraction lever when the winding body is in the first circumferential position.

[0027] A radial driver, connected to the unwinding lever, is used to drive the unwinding lever to move in a direction perpendicular to the rotation axis of the winding body;

[0028] An axial driver, connected to the radial driver, is used to drive the radial driver to move in a direction parallel to the rotation axis of the winding body.

[0029] In one embodiment, there are two or more unwinding levers, and at least two of the unwinding levers are respectively opposite to different spacer slots when the winding body is in the first circumferential position.

[0030] In one embodiment, the welding strip sampling and winding device further includes a wire baffle plate located circumferentially outside the winding body and extending along the axial direction of the winding body, and the wire baffle plate at least covers the winding area of ​​the winding body.

[0036] Compared with the prior art, this utility model has at least the following beneficial effects:

[0037] The aforementioned welding strip sampling and winding device, by setting the triggering mechanism of the gripper as a separate triggering component, separates the trigger block and drive rod inside and outside the winding mechanism, and sets alignment through holes on the rotating disk. When it is necessary to clamp or loosen the welding strip head, an external clamping driver can drive the drive rod through the through hole into the interior of the winding mechanism to trigger the trigger block, mechanically opening the gripper. At this point, the welding strip head can be placed on or removed from the gripper. Then, the clamping driver drives the drive rod out of the through hole, separating the drive rod from the trigger block. The gripper can then reclose under the action of the elastic element, achieving clamping or resetting of the welding strip head. Furthermore, since the drive rod is now outside the rotating disk, it will not interfere with the rotation of the rotating disk and the winding body, ensuring the reliability of the welding strip winding. Thus, by separating the dynamic and static components in the gripper's triggering component, automated clamping and unwinding operations can be achieved, avoiding wire tangling, ensuring the reliability of welding strip winding, and improving winding efficiency.

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0066] As described in the background section, current solder strip winding and sampling mainly relies on manual labor or equipment with low automation. Manual operation is inefficient and produces inconsistent quality; while existing winding machines still require manual operation in key steps such as solder strip fixing and unloading, resulting in continued low efficiency and difficulty in meeting production demands. In particular, fixing the solder strip head before winding is problematic because the wire clamping mechanism on the winding machine needs to rotate synchronously with the drum during winding. Therefore, existing wire clamping mechanisms are usually independent components mounted on the drum. To avoid tangling of external control circuitry, these clamping mechanisms are typically operated manually, leading to continued reliance on manual labor in the solder strip fixing / unloading process.

[0067] To address the aforementioned technical problems, this utility model provides a welding strip sampling and winding device, such as... Figure 1 As shown, it includes:

[0068] The winding mechanism 100 includes a rotating disk, a winding body 120 fixed to the rotating disk 110, and a winding driver 130 that drives the rotating disk 110.

[0069] Wire clamping mechanism 200, comprising:

[0070] The fixing seat 210 is fixed to the side of the rotating disk 110 facing the winding body 120;

[0071] The clamping assembly 220 includes a gripper 221 that is openably and closably disposed on the fixed base 210 and an elastic element 222 that provides a closing preload force for the gripper 221;

[0072] The separate trigger assembly 230 includes a trigger block 231, a drive rod 232, and a wire clamp driver 233; wherein,

[0073] The trigger block 231 is slidably mounted on the fixed base 210 to trigger the gripper 221 to open;

[0074] The drive rod 232 is located on the side of the rotating disk 110 away from the fixed base 210, and the rotating disk 110 is provided with a through hole 111 opposite to the trigger block 231;

[0075] The clamping driver 233 is used to drive the drive rod 232 through the through hole 111 to trigger the trigger block 231 or to exit the through hole 111 and separate from the rotating disk 110.

[0076] According to the welding strip sampling and winding device of this utility model embodiment, by setting the triggering mechanism of the gripper 221 as a separate triggering component, the trigger block 231 and the drive rod 232 are separately arranged inside and outside the winding mechanism 100, and a through hole 111 for alignment is provided on the rotating disk 110, so that when it is necessary to clamp or loosen the head of the welding strip 10, the external clamping driver 233 can drive the drive rod 232 to pass through the through hole 111 and extend into the inside of the winding mechanism 100 to trigger the trigger block 231, triggering the gripper 221 to open in a mechanical contact manner, at which time the welding strip 10 can be sampled and wound. The head of the solder ribbon 10 is placed on the gripper 221 or removed from the gripper 221. Then, the drive rod 232 is driven out of the through hole 111 by the wire clamping driver 233, causing the drive rod 232 to separate from the trigger block 231. At this time, the gripper 221 can close again under the action of the elastic element 222, realizing the clamping or reset of the head of the solder ribbon 10. Since the drive rod 232 has been withdrawn to the outside of the rotating disk 110, the drive rod 232 will not interfere with the rotation of the rotating disk 110 and the winding body 120, thus ensuring the reliability of the solder ribbon 10 winding. In this way, by separating the dynamic and static components in the trigger assembly of the gripper 221, the wire clamping and unwinding operations can be automated, avoiding wire tangling, ensuring the reliability of the solder ribbon 10 winding, and improving the winding efficiency.

[0077] The welding strip sampling and winding device provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0078] according to Figure 1 An exemplary embodiment of the present invention is shown, comprising a welding strip sampling and winding device including a winding mechanism 100 and a clamping mechanism 200.

[0079] like Figure 1 As shown, in this embodiment, the winding mechanism 100 and the clamping mechanism 200 are both mounted on a base plate 500, which is the fixed frame of the welding strip sampling winding device and is used to provide support for the winding mechanism 100 and the clamping mechanism 200 of the device.

[0080] Among them, see Figure 1 The winding mechanism 100 includes a rotating disk 110, a winding body 120 fixed to the rotating disk 110, and a winding driver 130 that drives the rotating disk 110. Based on this winding mechanism 100, the rotating disk 110 is driven to rotate by the winding driver 130, and then the rotating disk 110 drives the winding body 120 to rotate, so that the winding body 120 can wind the welding strip 10.

[0081] Specifically, in this embodiment, the rotating disk 110 is an intermediate connector between the winding body 120 and the winding driver 130, mainly used to support the winding body 120 and transmit power. It can be any suitable structure. Preferably, in this embodiment, the rotating disk 110 is a disc, which has better rotational stability compared to other shapes and structures, thus facilitating power transmission.

[0082] The winding body 120 and the winding driver 130 are respectively located on both axial sides of the rotating disk 110. The winding body 120 is the main body of the winding mechanism 100 and is used to wind the welding strip 10. For example, see... Figure 1 and Figure 4 In this embodiment, the winding body 120 may include winding plates 121 fixed on the rotating disk 110. The number of winding plates 121 is at least two, such as 2, 3, or 4. Figure 4 An exemplary embodiment is shown with four winding plates 121. With this configuration, the welding strip 10 can be wound by the rotating disk 110 through each winding plate 121.

[0083] Please continue reading Figure 4 In this embodiment, preferably, each winding piece 121 is evenly arranged on the rotating disk 110 along a circumference, and the center of the circumference where each winding piece 121 is located coincides with the rotation center of the rotating disk 110, so that the winding profile of the winding body 120 is cylindrical, which is beneficial to achieve uniform winding of the welding strip 10. For example, each winding piece 121 is disposed on the outer circumferential surface of the rotating disk 110.

[0084] Further, see Figure 4 The outer surface of each winding piece 121 is an arc-shaped surface, for example, the outer surface of each winding piece 121 is part of a cylindrical surface. This makes it easier for the solder strip 10 to wind along the ideal envelope curve, which can reduce the creases generated when the solder strip 10 is wound, avoid sudden stress changes at the fold point, and provide a basis for accurate testing of the solder strip 10 in subsequent processes.

[0085] Furthermore, in some embodiments, the winding laminations 121 are spaced apart along the circumferential direction, and the interval between two adjacent winding laminations 121 forms a spacer groove 122, and / or, the winding laminations 121 are provided with spacer grooves 122. For example, in Figure 4 In the example, each winding piece 121 is provided with a spacing groove 122, and there is also a spacing groove 122 between every two adjacent winding pieces 121. With this configuration, the spacing grooves 122 between the winding pieces 121 and the spacing grooves 122 on the winding pieces 121 can reduce the contact area between the solder ribbon 10 and the winding body 120 when the solder ribbon 10 is wound on the winding body 120, thereby reducing the resistance exerted by the winding body 120 on the solder ribbon 10 when removing the solder ribbon 10, thus making it easier to remove the solder ribbon 10.

[0086] In the above embodiments, the winding body 120 is composed of a plurality of winding plates 121. However, it should be understood that in practical applications, it is not limited to this. For example, in some embodiments, the winding body 120 can directly adopt a complete cylindrical structure, i.e., a drum; in other embodiments, the sheet-like winding plates 121 can be replaced with rod-like winding rods, which can also achieve the purpose of winding the welding strip 10.

[0087] See Figure 1 The winding driver 130 includes a drive motor 131, a belt drive mechanism 132, and a drive shaft (not shown in the figure). The drive motor 131 is fixedly mounted on the base plate 500; the drive shaft is rotatably mounted on the base plate 500, with one end fixedly connected to the rotating disk 110. This drive shaft serves two purposes: transmitting power to the rotating disk 110 and providing support for both the rotating disk 110 and the winding body 120. The other end of the drive shaft is connected to the output shaft of the drive motor 131 via the belt drive mechanism 132. With this configuration, when the drive motor 131 starts, it transmits torque to the drive shaft via the belt drive mechanism 132. The drive shaft then drives the rotating disk 110 to rotate, thus achieving the rotation and winding of the winding body 120.

[0088] It should be understood that in some other embodiments, the output shaft of the drive motor 131 may be directly connected to the rotating disk 110.

[0089] Furthermore, the winding device provided in this embodiment of the present invention also includes a counting mechanism, which includes a sensing sensor 141 and a sensing plate 142 that rotates synchronously with the winding body 120; the sensing sensor 141 is located on the rotation path of the sensing plate 142 and is used to provide a feedback signal when the sensing plate 142 passes by. For example, when the winding driver 130 uses a belt drive mechanism 132 as an intermediate drive mechanism, see [reference needed]. Figure 1The sensing sensor 141 can be a slotted photoelectric sensor fixed on the substrate 500. The principle and structure of the slotted photoelectric sensor are existing technologies and will not be described in detail here. The sensing plate 142 is fixedly mounted on the upper pulley of the belt drive mechanism 132, and the position of the sensing plate 142 corresponds to the sensing slot of the slotted photoelectric sensor. During operation, when the upper pulley rotates, it drives the winding body 120 and the sensing plate 142 to rotate synchronously. The sensing plate 142 can pass through the sensing slot of the slotted photoelectric sensor. When the sensing plate 142 passes through the sensing slot, it can trigger the slotted photoelectric sensor to generate a change in electrical signal. The slotted photoelectric sensor feeds back the electrical signal to the controller. The controller counts according to the electrical signal. Each time the sensing plate 142 passes through the sensing slot, it means that the upper pulley has rotated once, the winding body 120 has rotated once, and the welding ribbon 10 has been wound once. The controller counts once. In this way, the number of times the welding ribbon 10 is wound can be automatically recorded. When the number of times reaches the standard, the machine will stop automatically, which can ensure that the sampling length is consistent each time, eliminate the error of manual counting, and meet the stringent requirements of the testing standards for sampling accuracy.

[0090] In this embodiment, the wire clamping mechanism 200 is used to clamp the head of the solder strip 10 before winding, so as to facilitate the winding mechanism 100 to wind the solder strip 10 and ensure winding stability. (See also...) Figure 5 The wire clamping mechanism 200 specifically includes a fixed base 210, a clamping assembly 220, and a separate triggering assembly 230.

[0091] The fixing base 210 is a supporting component of the wire clamping mechanism 200, used to provide support for some components in the clamping assembly 220 and the separate trigger assembly 230. Specifically, as... Figure 5 As shown, the mounting base 210 includes two opposing and spaced-apart mounting plates 211. The upper and lower sides of the two mounting plates 211 are connected and fixed by connecting blocks 212, thus forming a single mounting base 210. A cavity is formed between the two spaced-apart mounting plates 211, which is a component for installing the clamping assembly 220 and the separate trigger assembly 230.

[0092] Please see Figure 2 , Figure 6 and Figure 7 The fixing seat 210 is fixedly installed on the side of the rotating disk 110 facing the winding body 120. Figure 6 (As shown, on the left side of the steering wheel), the fixing seat 210 and the winding body 120 are positioned on the same side of the rotating disk 110. Furthermore, the fixing seat 210 is fixed with its rear end perpendicular to the left side of the rotating disk 110, as... Figure 6 and Figure 7As shown. In this way, the through-extension direction of the cavity between the two fixed plates 211 can be the same as the axial direction of the rotating disk 110, so as to facilitate the cooperation of the moving and stationary components in the separate trigger assembly 230.

[0093] In this embodiment, the clamping assembly 220 includes grippers 221 that are openably and closably disposed within the cavity of the fixing base 210. See also Figure 6 and Figure 7 The gripper 221 specifically includes two clamping plates 2211. Each clamping plate 2211 includes a trigger end 22112 (right end in the figure) and a clamping end 22111 (left end in the figure). The trigger ends 22112 of the two clamping plates 2211 are embedded in the cavity of the fixed base 210 and are hinged to the two fixed plates 211 by a pin, so that the two clamping plates 2211 can swing up and down, thereby realizing that the clamping ends 22111 of the two clamping plates 2211 move closer or further away from each other, so as to perform the opening and closing action of the gripper 221.

[0094] The clamping assembly 220 also includes an elastic element 222 that provides a closing preload force for the grippers 221. See details... Figure 6 and Figure 7 The elastic element 222 includes two springs 2221. Each clamping plate 2211 has a spring 2221 positioned between its side away from the other clamping plate 2211 and the fixing base 210. These springs 2221 provide a force to the clamping plate 2211 towards the other clamping plate 2211. Taking the upper clamping plate 2211 as an example... Figure 6 As shown, a groove is provided on the upper side of the upper clamping plate (the upper clamping plate 2211). A limiting plate 213, opposite to the groove, is fixedly connected to the upper ends of the two fixing plates 211. A spring 2221 is disposed in the groove, with its upper end abutting against the limiting plate 213 and its lower end abutting against the upper clamping plate. The spring 2221 is in a compressed state, giving it a downward elastic force on the upper clamping plate. Thus, by applying a preload force to the upper and lower clamping plates (the lower clamping plate 2211) through the two springs 2221, the grippers 221 can remain closed without external force.

[0095] Further, see Figure 2 In this embodiment, the clamping assembly 220 is disposed inside the winding body 120. Correspondingly, at least one spacer slot 122 on the winding body 120 serves as a wire groove 123, for example in... Figure 4The slot 122 on the winding plate 121 on the right side is a groove 123. Here, the groove 123 is used to allow the head of the solder ribbon 10 to pass into the interior of the winding body 120 for clamping by the gripper 221. Therefore, the groove 123 should extend axially outward from at least a position on the winding body 120 radially opposite to the clamping end 22111 of the clamping plate 2211 to the outer end of the winding body 120 away from the rotating disk 110, allowing the head of the solder ribbon 10 to enter the winding body 120 from the front end along the groove 123 to the clamping assembly 220 or exit the winding body 120. Simultaneously, to facilitate the clamping of the head of the solder ribbon 10 by the gripper 221, the groove 123 also satisfies the following condition: the winding body 120 is in the first circumferential position (e.g.,...). Figure 2 When the wire groove 123 is in the circumferential position shown, it is exactly opposite to the opening of the clamp 221 when it is open. This makes it easy for the head of the solder ribbon 10 to be inserted into the winding body 120 from the designated position and then directly clamped by the clamp 221, which facilitates automated operation. In addition, by placing the clamping assembly 220 inside the winding body 120, the structure of this device can be made more compact, reducing the volume occupied by this device.

[0096] See Figures 5 to 7 The separate trigger assembly 230 includes a trigger block 231, a drive rod 232, and a wire clamping driver 233. The trigger block 231, located inside the winding mechanism 100, is a moving component that triggers the opening of the clamp 221 and moves synchronously with the rotating disk 110 and winding body 120 during winding. The drive rod 232 and the wire clamping driver 233 drive the trigger block 231; both are located outside the winding mechanism 100 and are stationary components, remaining stationary during winding. This separation of the moving and stationary components in the trigger assembly enables automated wire clamping and unwinding operations, preventing wire tangling and ensuring the reliability of the solder ribbon 10 winding.

[0097] Specifically, such as Figure 6 and Figure 7As shown, the trigger block 231 is slidably disposed in the cavity of the fixed base 210 and located on one side of the trigger end 22112 of the clamping plate 2211. The front end of the trigger block 231 and the trigger ends 22112 of the two clamping plates 2211 have a matching trigger structure. The trigger structure includes an arc-shaped contact surface 2212 disposed on the side where the trigger ends 22112 of the two clamping plates 2211 are close to each other. A gap is provided between the two arc-shaped contact surfaces 2212. The front end of the trigger block 231 facing the clamping claw 221 is provided with a wedge-shaped end 2311 that can be inserted into the gap. Based on this structural design, when the trigger block 231 slides forward, its wedge-shaped end 2311 can be inserted into the gap between the two arc-shaped contact surfaces 2212, so that the upper and lower wedge surfaces of the wedge-shaped end 2311 contact the two arc-shaped contact surfaces 2212 respectively. Then the trigger block 231 continues to move forward, and the insertion force of the wedge-shaped end 2311 of the trigger block 231 acts on the side of the trigger ends 22112 of the two clamping plates 2211 that are close to each other through the wedge surface, and is converted into an axial component force, pushing the two clamping plates 2211 forward. However, since the trigger ends 22112 of the clamping plates 2211 are hinged to the fixed seat 210, the clamping plates 2211 as a whole will rotate around the hinge point, thereby causing the clamping ends 22111 of the two clamping plates 2211 to open.

[0098] See Figure 5 , Figure 6 and Figure 7 In a specific example, the connecting blocks 212 on the upper and lower sides of the fixed base 210 are provided with sliding holes (not labeled in the figure) extending along the axial direction of the rotating disk 110, and the upper and lower sides of the trigger block 231 are provided with sliding rods (not labeled in the figure) that slide with the sliding holes, so that the sliding engagement between the trigger block 231 and the fixed base 210 can be realized.

[0099] In this embodiment, the drive rod 232 is located on the side of the rotating disk 110 away from the fixed base 210, that is, on the outer side of the rotating disk 110, and has a separable / contactable engagement with the trigger block 231. Specifically, see [link to documentation]. Figure 2 The drive rod 232 is mounted on the substrate 500 via the wire clamping actuator 233, located behind the rotating disk 110. A through hole 111 is provided through the rotating disk 110, which is axially opposite to the trigger block 231 and the drive rod 232. With this structural design, when it is necessary to loosen or clamp the head of the solder ribbon 10, the wire clamping actuator 233 drives the drive rod 232 to move forward, such as... Figure 6 As shown, the drive rod 232 can pass through the through hole 111 and extend into the inner side of the rotating disk 110, pushing the trigger block 231 forward, causing the trigger block 231 to trigger the gripper 221 to open. At this time, the head of the solder ribbon 10 can be removed or placed into the gripper 221. Subsequently, the wire clamping driver 233 drives the drive rod 232 to move backward, as shown. Figure 7As shown, the drive rod 232 can exit through the through hole 111 and move to the outside of the rotating disk 110, so that the drive rod 232 separates from the rotating disk 110 and the trigger block 231. At this time, the spring 2221 will drive the two clamping plates 2211 to close and push the trigger block 231 to move backward to reset, thereby resetting the gripper 221 or clamping the head of the welding strip 10.

[0100] In this embodiment, the clamping driver 233 can specifically be a cylinder. See also Figure 2 The cylinder is fixedly mounted on the base plate 500, and the piston rod of the cylinder is axially opposite to the through hole 111, and the drive rod 232 is fixedly connected to the end of the piston rod.

[0101] See Figure 1 and Figure 9 The winding device also includes a wire-blocking plate 400 fixed to the substrate 500. The wire-blocking plate 400 is located circumferentially outside the winding body 120 and extends along the axial direction of the winding body 120, and the wire-blocking plate 400 at least covers the winding area of ​​the winding body 120. The winding area of ​​the winding body 120 can be understood as the area on the winding body 120 used for winding the solder ribbon 10, for example, the area on the winding body 120 radially opposite to the gripper 221, see [reference needed]. Figure 1 Preferably, the wire baffle 400 completely covers the winding body 120 axially. According to this structural design, during the process of winding the welding strip 10 around the winding body 120, the welding strip 10 can be radially limited by the wire baffle 400 on the outside of the winding body 120, ensuring the compactness of the wound welding strip 10 and preventing the winding from becoming tangled.

[0102] Further, see Figure 1 and Figure 9 In this embodiment, two wire-blocking plates 400 are provided, which are symmetrically arranged on the upper and lower sides of the winding body 120. In this way, the limiting effect on the welding strip 10 can be strengthened, further ensuring the compactness of the wound welding strip 10 and preventing the winding from becoming messy.

[0103] Furthermore, see Figure 9 The wire baffle 400 has an arc-shaped constraint surface 410 coaxial with the winding body 120 on the side facing the winding body 120. The arc-shaped constraint surface 410 extends circumferentially along the winding body 120. In this configuration, by setting the arc-shaped constraint surface 410 coaxial with the winding body 120, a channel matching the winding trajectory is formed, so that the welding strip 10 is always uniformly radially constrained during the winding process, preventing the winding from becoming loose.

[0104] It should be noted that the distance between the arc-shaped constraint surface 410 and the outer surface of the winding body 120 can be set according to the thickness of the welding strip 10 and the number of turns of the welding strip 10. For example, if the thickness of the welding strip 10 is d, and the welding strip sampling winding is usually wound 3-5 times, then the distance between the arc-shaped constraint surface 410 and the outer surface of the winding body 120 can be set to be equal to or slightly greater than 5d, which can ensure the compactness of the wound welding strip 10.

[0105] See Figure 1 and Figure 3 In this embodiment, the winding device further includes a wire unwinding mechanism 300, which includes a wire unwinding lever 310, a radial driver 320, and an axial driver 330. The wire unwinding lever 310 is located circumferentially outside the winding body 120, with its axis perpendicular to the rotation axis of the winding body 120. The radial driver 320 is connected to the wire unwinding lever 310 and drives the wire unwinding lever 310 to move in a direction perpendicular to the rotation axis of the winding body 120. The axial driver 330 is connected to the radial driver 320 and drives the radial driver 320 to move in a direction parallel to the rotation axis of the winding body 120.

[0106] Specifically, such as Figure 3 and Figure 8 As shown, in this embodiment, both the axial actuator 330 and the radial actuator 320 are cylinders. The cylinder body of the axial actuator 330 is fixedly mounted on the base plate 500, and the extension / retraction direction of the piston rod of the axial actuator 330 is parallel to the rotation axis of the winding body 120. A mounting plate 340 is fixedly connected to the end of the piston rod. The cylinder body of the radial actuator 320 is fixedly mounted on the mounting plate 340, and the piston rod of the radial actuator 320 faces the winding body 120, with its extension / retraction direction perpendicular to the rotation axis of the winding body 120. A connecting plate 350 is fixedly connected to the end of the piston rod of the radial actuator 320, and a retraction lever 310 is fixedly mounted on the side of the connecting plate 350 facing the winding body 120. The axis of the retraction lever 310 is perpendicular to the rotation axis of the winding body 120. (See also...) Figure 3 The winding body 120 is provided with a slot 124, which is formed by a spacer groove 122 between adjacent winding pieces 121, when the winding body 120 is in the first circumferential position ( Figure 3(As shown in the circumferential position), the unwinding lever 310 is radially aligned with the slot 124 on the winding body 120. Based on this structural design, when it is necessary to remove the wound solder ribbon 10, the winding body 120 is rotated to the first circumferential position, so that the unwinding lever 310 is aligned with the slot 124. Then, the radial driver 320 drives the unwinding lever 310 closer to the winding body 120 until the unwinding lever 310 is inserted into the slot 124. Then, the axial driver 330 drives the radial driver 320 and the unwinding lever 310 to move axially, so that the unwinding lever 310 moves along the slot 124 toward the outer end of the winding body 120. During this process, the unwinding lever 310 can push the solder ribbon 10 wound on the winding body 120 outward until the solder ribbon 10 is detached from the winding body 120.

[0107] Furthermore, there are two or more unwinding levers 310, and at least two of the unwinding levers 310 are respectively opposite to different spacer slots 122 when the winding body 120 is in the first circumferential position. For example, see Figure 8 There are two retraction levers 310, which are arranged at intervals in the vertical direction. See [reference needed]. Figure 3 When the winding body 120 is in the first circumferential position, the two unwinding levers 310 are directly opposite the two slots 124 (the lower slot is not shown). In this way, the solder strip 10 can be moved synchronously by the two unwinding levers 310, which improves the reliability of unwinding the solder strip 10.

[0108] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
