Description

Technical Field

[0001] The utility model relates to the technical field of solder ribbon packaging, in particular to an automatic wire pulling device for photovoltaic solder ribbons. Background Art

[0002] After the current photovoltaic solder ribbon is produced by the equipment, it needs to be wound around a plurality of take-up shafts according to a set length to form a plurality of single-axis finished products. When the take-up shaft is wound with the photovoltaic solder ribbon of the set length, it is necessary to cut off the photovoltaic solder ribbon on the take-up shaft from the subsequent equipment on the photovoltaic solder ribbon by a flying knife. However, when the flying knife cuts off the solder ribbon, the cutting point will be impacted by the flying knife, resulting in the change of the internal structure of the solder ribbon with a length ranging from 1 to 50 meters (varying according to product specifications) before and after the cutting point, so that the solder ribbon of this section cannot meet the use requirements. Therefore, the 1 - 50 meters of solder ribbon at the front end and the 1 - 50 meters of solder ribbon at the rear end of the produced single-axis finished product cannot be used.

[0003] Before selling the single-axis finished product, it is necessary to remove the 1 - 50 meters of solder ribbon at the front section of the solder ribbon on the single-axis finished product. The existing solution is to manually pull out and cut the 1 - 50 meters of solder ribbon at the front end. However, the length of the solder ribbon pulled out by manual wire pulling is not easy to control, and the manual wire pulling takes a long time. It is necessary to manually pull down the solder ribbon one by one, which is a waste of time. Summary of the Utility Model

[0016] In an embodiment of the utility model: The driven guide wheel is slidably connected to the first mounting rod, and the driven guide wheel is configured to be able to slide axially along the first mounting rod.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] It should be noted that the "first", "second" and similar terms used in the present utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. The descriptions of directions such as "left", "right", "left side", "right side", "upper part", "lower part", "top", "bottom" in the present utility model are all defined based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the structure must be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In the description of the present utility model, "a plurality" means more than two, unless otherwise specifically defined.

[0026] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] Please refer to Figure 1 and Figure 2 As shown, the present utility model is an automatic wire pulling device for photovoltaic solder tapes, including a wire paying-off mechanism 10, a wire pulling mechanism 11, a length measuring mechanism 12, and a control circuit (not shown). The wire paying-off mechanism 10 is provided with a wire paying-off station for placing a take-up spool 200, and when the take-up spool 200 is placed on the wire paying-off station, the wire paying-off mechanism 10 can drive the take-up spool 200 to rotate around its axis for wire paying-off. The side wire mechanism is arranged on one side of the wire paying-off mechanism 10. The side wire mechanism includes a wire take-up guide pulley 111 for taking up wire, a wire clamping gear 112 fixedly arranged at one end of the wire take-up guide pulley 111, and a wire pulling driving member 113 for driving the wire take-up guide pulley 111 and the wire clamping gear 112 to rotate synchronously. The waste wire 201 (the unusable photovoltaic solder tape on the take-up spool 200) on the take-up spool 200 can be manually pulled onto the wire take-up guide pulley 111, and one end of the waste wire 201 is clamped on the wire clamping gear 112. The wire pulling driving member 113 pulls out the waste wire 201 on the take-up spool 200 located on the wire paying-off station and winds it around the wire take-up guide pulley 111 to realize automatic collection of the waste wire 201. The length measuring mechanism 12 is used to measure the length of the waste wire 201 pulled out from the take-up spool 200 after the wire take-up guide pulley 111 rotates. The control circuit is electrically connected to the length measuring mechanism 12, the wire pulling mechanism 11, and the wire pulling mechanism 11. The length of the pulled-out waste wire 201 is automatically measured through the length measuring mechanism 12. When the length measuring mechanism 12 measures that the length of the waste wire 201 pulled out from the take-up spool 200 reaches the set length, the control circuit controls the wire pulling mechanism 11 and the wire pulling mechanism 11 to stop in time. Compared with the existing wire pulling by hand, the wire pulling by the device provided in this application improves the wire pulling efficiency and enables the length of the pulled wire to be accurately controlled, solving the problem that it is difficult to master the length of the solder tape pulled out by manual wire pulling.

[0028] Specifically, the wire pay-off mechanism 10 includes a wire pay-off rack 101, two horizontally spaced rollers 102, and a wire pay-off driving member 103. The wire pay-off rack 101 is generally an L-shaped frame. The axial directions of the two rollers 102 are both arranged horizontally, and both are rotatably installed on the wire pay-off rack 101 through bearings, forming a wire pay-off station between the two rollers 102. When the take-up shaft 200 is placed on the wire pay-off station, the two rollers 102 support the take-up shaft 200 from both sides at the bottom, making the axial direction of the take-up shaft 200 the same as the axial direction of the rollers 102. The wire pay-off station set in this application is very convenient for placing the take-up shaft 200.

[0029] The wire pay-off driving member 103 can drive at least one roller 102 to rotate, and then drive the take-up shaft 200 to rotate through the roller 102, facilitating the subsequent synchronous rotation of the take-up shaft 200 and the wire take-up guide wheel 111 to achieve synchronous wire take-up and pay-off. In this embodiment, the wire pay-off driving member 103 is a motor, and is arranged on one side of the roller 102 and fixedly installed on the wire pay-off rack 101. The wire pay-off driving member 103 is connected to one of the rollers 102 through a synchronous belt.

[0030] In this embodiment, the wire pay-off rack 101 is arranged on the weighing mechanism 13. The weighing mechanism 13 is used to detect the weight of the finished single shaft, enabling the staff to quickly obtain the weight of the finished single shaft after removing the waste wire 201 through the weighing mechanism 13, which is convenient for subsequently determining the price of the finished single shaft according to the detected weight. The weighing mechanism 13 can adopt an electronic scale.

[0031] The automatic wire pulling device for photovoltaic solder tapes further includes an installation box 14 and a vertical plate 15 fixedly arranged on the top of the installation box 14. The installation box 14 is generally a rectangular box with a cavity. The vertical plate 15 is a flat plate structure, vertically installed on the top of the installation box 14. The vertical plate 15 has an opposite first surface and second surface. A second installation rod 16 is installed on the vertical plate 15. The axial direction of the second installation rod 16 is the same as the axial direction of the roller 102, and the axial direction of the second installation rod 16 is perpendicular to the vertical plate 15. A part of the second installation rod 16 penetrates through the vertical plate 15 and extends out of the second surface, and the second installation rod 16 is rotatably connected to the vertical plate 15 through a bearing. The wire take-up guide wheel 111 is fixedly installed on the second installation rod 16 and is located on one side of the first surface. The wire clamping gear 112 is fixedly installed on the end surface of the wire take-up guide wheel 111 close to the vertical plate 15 through bolts, and is coaxially arranged with the wire take-up guide wheel 111 and the second installation rod 16. The wire pulling driving member 113 is a motor, fixedly installed on the first surface of the vertical plate 15. The motor shaft of the wire pulling driving member 113 penetrates through the vertical plate 15 and extends out of the second surface, and is connected to the part of the second installation rod 16 extending out of the second surface through a synchronous belt. The wire pulling driving member 113 drives the second installation rod 16 to rotate, driving the wire clamping gear 112 and the wire take-up guide wheel 111 to rotate synchronously, enabling the wire take-up guide wheel 111 to take up the wire.

[0032] The wire take-up guide pulley 111 has a tapered wall 1111 that tapers away from the wire clamping gear 112. The waste wire 201 is wound around the tapered wall 1111. When it is necessary to remove the waste wire 201 from the wire take-up guide pulley 111 later, it is only necessary to axially remove the waste wire 201 from the tapered wall 1111, which is very convenient for removing the waste wire 201 from the wire take-up guide pulley 111.

[0033] The length measuring mechanism 12 includes a length measuring guide pulley 121 and a length meter controller 122. The length measuring guide pulley 121 is rotatably installed on the vertical plate 15 and is provided on one side of the first surface. The length meter controller 122 is installed at the top of the installation cavity and is electrically connected to the length measuring guide pulley 121. The length meter controller 122 has an adjustment button and a length display area. The staff can set the set length of the waste wire 201 to be pulled from the wire take-up shaft 200 through the adjustment button in the length meter controller 122 and display it in the length display area. The length measuring guide pulley 121 is located between the wire take-up shaft 200 and the wire take-up guide pulley 111. After the waste wire 201 is pulled out from the wire take-up shaft 200, it needs to pass through the length measuring guide pulley 121 first and then be taken up by the wire take-up guide pulley 111. During the process of being pulled out, the waste wire 201 can drive the length measuring guide pulley 121 to rotate synchronously through friction, so that the length meter controller 122 measures the length of the waste wire 201 pulled out by detecting the number of rotation turns of the length measuring guide pulley 121, and also displays the pulled-out length of the waste wire 201 in the length display area, which is convenient for the staff to observe and compare the pulled-out length and the set length. When the pulled-out length is equal to the set length, the control circuit controls the wire feeding driving part 103 and the wire take-up driving part to stop running.

[0034] The control circuit includes a circuit controller and wires connecting the circuit controller to the length meter controller 122, the wire feeding driving part 103, and the wire take-up driving part. The circuit controller is provided in the installation box 14. When the length meter controller 122 detects that the pulled-out length reaches the set length, the circuit controller controls the wire feeding driving part 103 and the wire take-up driving part to stop running.

[0035] A human-machine interface 17 is provided on the front of the installation box 14. The staff can adjust the rotation speeds of the wire feeding driving part 103 and the wire take-up driving part through the human-machine interface 17, and then realize the adjustment of the rotation speeds of the wire take-up shaft 200 and the wire take-up guide pulley 111, so that the wire feeding speed of the wire take-up shaft 200 is equal to the wire take-up speed of the wire take-up guide pulley 111.

[0036] A cooling fan 18 is installed on the back of the installation box 14. The cooling fan 18 is used to dissipate heat from the inside of the installation box 14, avoid the temperature in the installation box 14 from being too high, and improve the service life of the circuit controller and the human-machine interface 17.

[0037] In this embodiment, a vertical rod 19 is fixedly installed on the wire pay-off rack 101. At the top of the vertical rod 19, a horizontally arranged first mounting rod 20 is fixedly installed. A driven idler wheel 21 is provided on the first mounting rod 20. The driven idler wheel 21 is located above the wire pay-off station and the length measuring idler wheel 121 in the vertical direction, so that there is a certain height difference between the driven idler wheel 21 and the take-up shaft 200 and the length measuring idler wheel 121 at the wire pay-off station. After the waste wire 201 is pulled out from the take-up shaft 200, it needs to pass through the driven idler wheel 21 and the length measuring idler wheel 121 in sequence and then be taken up by the take-up idler wheel 111. Through the setting of the driven idler wheel 21, there is enough contact length between the waste wire 201 and the take-up idler wheel 111, ensuring the friction force between the waste wire 201 and the take-up idler wheel 111, so that the take-up idler wheel 111 can be smoothly driven to rotate synchronously during the pulling process of the waste wire 201, ensuring the accuracy of the length measuring mechanism 12 for measuring the length of the waste wire 201.

[0038] Furthermore, the driven idler wheel 21 is slidably sleeved on the first mounting rod 20, enabling the driven idler wheel 21 to slide relative to the first mounting rod 20 along the axial direction of the first mounting rod 20. When the waste wire 201 is pulled out from different positions on the take-up shaft 200 in its axial direction, it can drive the driven idler wheel 21 to slide along the axial direction of the first mounting rod 20, so that the projection of the intersection point of the waste wire 201 and the top of the driven idler wheel 21 can be generally located on the projection of the connection line between the intersection point of the waste wire 201 and the take-up shaft 200 and the intersection point of the waste wire 201 and the bottom end of the length measuring idler wheel 121. Thereby ensuring that the waste wire 201 can generally walk along the circumferences of the driven idler wheel 21 and the length measuring idler wheel 121 simultaneously, improving the smoothness of the waste wire 201 walking on the driven idler wheel 21 and the length measuring idler wheel 121, and avoiding the waste wire 201 deviating from the circumferences of the driven idler wheel 21 and the length measuring idler wheel 121 and getting stuck between the length measuring idler wheel 121 and the driven idler wheel 21. A greater pulling force is required to pull the waste wire 201 to continue walking, which easily causes the internal structure of a section of good photovoltaic solder tape near the waste wire 201 to be damaged under the action of the large pulling force, thereby generating new waste wire 201 and affecting the product quality.

[0039] When it is necessary to pull out the waste wire 201 on the take-up spool 200, first place the take-up spool 200 on the wire-feeding station, so that the two rollers 102 support the take-up spool 200. Then, manually pull out a section of the waste wire 201 from the take-up spool 200 and pass it through the top of the driven guide wheel 21 and the bottom of the length-measuring guide wheel 121 in sequence, and then wind it around the wire-receiving guide wheel 111. And the end of this section of the waste wire 201 is stuck in the tooth gap between two adjacent teeth of the wire-clamping gear 112. After that, set the set length value on the length-meter controller 122 according to the length of the waste wire 201 to be pulled out from the take-up spool 200 this time. Then, turn on the automatic wire-pulling device for the photovoltaic solder tape, so that the wire-pulling driving member 113 drives the wire-receiving guide wheel 111 to rotate to pull out the waste wire 201 on the take-up spool 200 and wind it around its conical wall 1111. At the same time, the wire-feeding mechanism 10 drives the take-up spool 200 to rotate synchronously to feed the wire, so as to avoid the photovoltaic solder tape being pulled too tightly between the wire-receiving guide wheel 111 and the take-up spool 200 during the wire-receiving process, resulting in excessive stress on the good photovoltaic solder tape on the take-up spool 200 and causing damage. During the wire-receiving process of the take-up spool 200, the length-meter controller 122 measures the length of the waste wire 201 pulled out from the take-up spool 200 in real time according to the number of turns of the length-measuring guide wheel 121. When the length of the pulled-out waste wire 201 reaches the set length, the circuit controller controls the wire-feeding mechanism 10 and the wire-pulling driving member 113 to stop, so that the take-up spool 200 stops feeding the wire and the wire-receiving guide wheel 111 stops receiving the wire. Then, the staff cuts the pulled-out photovoltaic solder tape near the take-up spool 200, and the removal of the waste wire 201 of a single-axis finished product is completed.

[0040] In this application, by setting the length-measuring mechanism 12, the accuracy of the length of the photovoltaic solder tape pulled out from the take-up spool 200 is ensured, avoiding waste caused by too long a length of the removed photovoltaic solder tape or residue of the waste wire 201 caused by too short a length. And in this application, by setting the wire-feeding mechanism 10, the wire-feeding mechanism 10 drives the take-up spool 200 to actively rotate and feed the wire synchronously when the wire-receiving guide wheel 111 receives the wire. Compared with the take-up spool 200 being driven to rotate passively to feed the wire when the wire-receiving guide wheel 111 receives the wire, there is a certain degree of slack in the photovoltaic solder tape between the wire-receiving guide wheel 111 and the take-up spool 200, avoiding the waste wire 201 being overly tightened when the wire-receiving guide wheel 111 receives the wire, resulting in the good photovoltaic solder tape on the take-up spool 200 being pulled and scrapped, generating new waste wire 201.

[0041] The above has described an embodiment of the present invention in detail, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
