Description

Technical Field

[0001] The present invention relates to the field of battery production, in particular to a welding ribbon traction device and a traction method. Background Art

[0002] Multi-grid solar cells typically have 2 to 6 grid lines, meaning each cell uses 2 to 6 fixed-length ribbons arranged side by side on a single side. As demand for cell photoelectric conversion efficiency increases, dense-grid cells with more grid lines are appearing on the market. The ribbons placed on the grid lines are pulled from the ribbon reel by the stringer's ribbon pulling device and cut to a predetermined length.

[0003] Traditional ribbon pulling devices pull the ribbon as follows: The pulling mechanism is controlled to clamp the ribbon after the cutter mechanism and pull it to a predetermined position. The ribbon clamping mechanism is then controlled to clamp the ribbon before the cutter mechanism. Finally, the cutter mechanism is controlled to cut the ribbon, resulting in a predetermined length of ribbon. Next, the pulling mechanism is controlled to clamp the ribbon after the cutter mechanism and pull the next section of ribbon. In other words, the cutter mechanism must wait for the ribbon clamping mechanism to clamp the ribbon before it can cut it, and the pulling mechanism must wait for the cutter mechanism to cut the ribbon before it can pull the next section of ribbon. Traditional ribbon pulling devices have low ribbon pulling efficiency. Summary of the Invention

[0004] Aiming at the technical problem of low traction efficiency in traditional welding ribbon traction devices, the present invention proposes a welding ribbon traction device, which includes a cutter mechanism, a first welding ribbon traction mechanism and a second welding ribbon traction mechanism.

[0005] The first welding ribbon pulling mechanism and the second welding ribbon pulling mechanism are configured to alternately clamp the welding ribbon at a pulling station located before the cutting station, and pull the clamped welding ribbon to a transfer station located after the cutting station, wherein:

[0006] When the first welding ribbon pulling mechanism pulls the clamped welding ribbon to the transfer station, the second welding ribbon pulling mechanism clamps the welding ribbon at the pulling station, and the cutter mechanism cuts the welding ribbon at the cutting station to obtain a welding ribbon segment with a predetermined length;

[0007] When the second welding ribbon pulling mechanism pulls the clamped welding ribbon to the transfer station, the first welding ribbon pulling mechanism clamps the welding ribbon at the pulling station, and the cutter mechanism cuts the welding ribbon at the cutting station to obtain a welding ribbon segment with a predetermined length.

[0008] The welding ribbon traction device provided by the present invention is equipped with two welding ribbon traction mechanisms. The two welding ribbon traction mechanisms alternately clamp the welding ribbon at the traction station in front of the cutter mechanism and pull the welding ribbon to the transfer station in the back. While one welding ribbon traction mechanism pulls the previous section of welding ribbon to the transfer station, the other welding ribbon traction mechanism can synchronously clamp the next section of welding ribbon at the traction station without waiting for the cutter mechanism to cut the welding ribbon. In addition, because the welding ribbon in the front of the cutter mechanism has been clamped by the welding ribbon traction mechanism at the traction station, the cutter mechanism can cut the welding ribbon without waiting for the welding ribbon clamping mechanism to clamp the welding ribbon. Compared with traditional welding ribbon traction devices, the welding ribbon traction device provided by the present invention significantly improves the welding ribbon traction efficiency.

[0009] In some embodiments, the welding ribbon traction device further includes a welding ribbon lifting mechanism arranged between the cutting station and the transfer station; the welding ribbon lifting mechanism is used to lift the welding ribbon pulled to the transfer station by the first welding ribbon traction mechanism or the second welding ribbon traction mechanism.

[0010] By setting up the welding ribbon lifting mechanism, the welding ribbon guided to the transfer station is lifted and supported to prevent the welding ribbon from falling.

[0011] In some embodiments, the welding ribbon lifting mechanism includes a lifting part and a first lifting drive part, wherein: the lifting part is connected to the first lifting drive part, and the first lifting drive part drives the lifting part to rise and fall; when the lifting part is driven by the first lifting drive part to descend to a low position, it avoids the first welding ribbon traction mechanism or the second welding ribbon traction mechanism; when the lifting part is driven by the first lifting drive part to rise to a high position, it lifts the welding ribbon.

[0012] By setting the welding tape lifting mechanism, the welding tape lifting mechanism can avoid the first welding tape traction mechanism or the second welding tape traction mechanism when the first welding tape traction mechanism or the second welding tape traction mechanism is traction of the welding tape. After the first welding tape traction mechanism or the second welding tape traction mechanism completes traction of the welding tape, the welding tape is lifted, supported and guided.

[0013] In some embodiments, the welding ribbon traction device further includes a clamping mechanism arranged in front of the traction station; when the first welding ribbon traction mechanism or the second welding ribbon traction mechanism clamps the welding ribbon at the traction station for the first time, the clamping mechanism clamps the free end of the welding ribbon.

[0014] By providing the clamping mechanism, when the first welding strip pulling mechanism or the second welding strip pulling mechanism pulls the welding strip for the first time, the clamping mechanism achieves clamping and positioning of the free end of the welding strip.

[0015] In some embodiments, the cutter mechanism includes a cutter and a second lifting drive unit, wherein: the cutter is connected to the second lifting drive unit, and the second lifting drive unit is used to drive the cutter to rise and fall; when the cutter is driven by the second lifting drive unit to descend to a low position, it avoids the first weld ribbon traction mechanism or the second weld ribbon traction mechanism; when the cutter is driven by the second lifting drive unit to rise to a high position, it cuts off the weld ribbon.

[0016] By setting the cutter mechanism, the cutter mechanism avoids the first weld ribbon traction mechanism or the second weld ribbon traction mechanism when the first weld ribbon traction mechanism or the second weld ribbon traction mechanism is tractioning the weld ribbon, and cuts the weld ribbon after the first weld ribbon traction mechanism or the second weld ribbon traction mechanism completes traction of the weld ribbon.

[0017] In some embodiments, the welding ribbon traction device further includes a welding ribbon transfer mechanism; the welding ribbon transfer mechanism is used to clamp the welding ribbon pulled to the transfer station by the first welding ribbon traction mechanism or the second welding ribbon traction mechanism, and to pull the obtained welding ribbon segment to the subsequent station.

[0018] By setting up the welding ribbon transfer mechanism, the welding ribbon pulled to the transfer station can be received, and the cut welding ribbon segment can be automatically transferred to the subsequent station.

[0019] In some embodiments, the ribbon transfer mechanism includes a third ribbon traction mechanism and a fourth ribbon traction mechanism, which alternately clamp the ribbon from the transfer station and pull the ribbon segment to a subsequent station.

[0020] The third welding ribbon pulling mechanism and the fourth welding ribbon pulling mechanism are used to alternately clamp the welding ribbon from the transfer station and pull the welding ribbon segment to the subsequent station, thereby improving the transfer efficiency of the welding ribbon.

[0021] In some embodiments, the weld ribbon traction device further includes a mounting base, a first guide rail and a second guide rail, wherein: the first guide rail and the second guide rail are arranged side by side on the mounting base along the extension direction of the weld ribbon; the first weld ribbon traction mechanism and the fourth weld ribbon traction mechanism are slidably mounted on the first guide rail, the first weld ribbon traction mechanism slides along the first guide rail to realize position switching between the traction station and the transfer station, and the fourth weld ribbon traction mechanism slides along the first guide rail to realize position switching between the transfer station and the downstream station; the second weld ribbon traction mechanism and the third weld ribbon traction mechanism are slidably mounted on the second guide rail, the second weld ribbon traction mechanism slides along the second guide rail to realize position switching between the traction station and the transfer station, and the third weld ribbon traction mechanism slides along the second guide rail to realize position switching between the transfer station and the downstream station.

[0022] By setting the mounting base, the first guide rail and the second guide rail, the sliding installation of the first welding ribbon traction mechanism, the second welding ribbon traction mechanism, the third welding ribbon traction mechanism and the fourth welding ribbon traction mechanism is realized, so that each welding ribbon traction mechanism can move and switch between the corresponding target stations to complete the corresponding action.

[0023] In some embodiments, the first welding ribbon traction mechanism, the second welding ribbon traction mechanism, the third welding ribbon traction mechanism and the fourth welding ribbon traction mechanism all include a sliding bracket, a mounting plate, a clamping drive mechanism, a first clamping mechanism and a second clamping mechanism, wherein: the sliding bracket is connected to the first guide rail or the second guide rail, and the mounting plate is installed on the sliding bracket; the first clamping mechanism includes a first clamping plate slidably mounted on the mounting plate and a plurality of first clamping jaws arranged on the first clamping plate, the second clamping mechanism includes a second clamping plate fixedly mounted on the mounting plate and a plurality of second clamping jaws arranged on the second clamping plate, the first clamping jaw and the second clamping jaw are spaced apart, and adjacent first clamping jaws and second clamping jaws constitute a group of clamping jaws; the clamping drive mechanism is used to drive the first clamping plate to translate relative to the second clamping plate, so that the first clamping jaw and the second clamping jaw in each group of clamping jaws are clamped or separated to achieve clamping or release of a welding ribbon.

[0024] Through the cooperation of the first clamping mechanism and the second clamping mechanism, the welding ribbon traction mechanism realizes synchronous clamping and synchronous traction of multiple welding ribbons, which improves the traction efficiency of the welding ribbons.

[0025] In some embodiments, a first weld ribbon clamping groove is provided on the clamping surface of the first clamping jaw, and a second weld ribbon clamping groove corresponding to the first weld ribbon clamping groove is provided on the clamping surface of the second clamping jaw. When the first clamping jaw and the second clamping jaw are clamped, the first weld ribbon clamping groove and the second weld ribbon clamping groove cooperate to clamp the weld ribbon.

[0026] By arranging the first welding strip clamping groove and the second welding strip clamping groove on the first clamping jaw and the second clamping jaw, when clamping the flat welding strip, the flat welding strip enters and is clamped in the clamping groove, thereby preventing the flat welding strip from curling and deforming.

[0027] The present invention also provides a welding ribbon pulling method, which comprises:

[0028] Controlling the first welding ribbon pulling mechanism to clamp the welding ribbon at a pulling station located before the cutting station, and pulling the clamped welding ribbon to a transfer station located after the cutting station;

[0029] Controlling the second welding ribbon pulling mechanism to clamp the welding ribbon at the pulling station when the first welding ribbon pulling mechanism pulls the welding ribbon to the transfer station;

[0030] Controlling the cutter mechanism to cut the welding ribbon at the cutting station to obtain a welding ribbon segment with a predetermined length;

[0031] Controlling the second welding ribbon pulling mechanism to pull the clamped welding ribbon to the transfer station;

[0032] When the second welding ribbon pulling mechanism pulls the welding ribbon to the transfer station, the first welding ribbon pulling mechanism is controlled to clamp the welding ribbon at the pulling station to pull the next section of welding ribbon.

[0033] The present invention's welding ribbon pulling method controls two welding ribbon pulling mechanisms to alternately clamp the welding ribbon at a pulling station in front of a cutter mechanism and pull the welding ribbon to a subsequent transfer station. While one welding ribbon pulling mechanism pulls the previous section of welding ribbon to the transfer station, the other welding ribbon pulling mechanism can simultaneously clamp the next section of welding ribbon at the pulling station without waiting for the cutter mechanism to cut the welding ribbon. Furthermore, since the welding ribbon in front of the cutter mechanism is already clamped by the welding ribbon pulling mechanism at the pulling station, the cutter mechanism can cut the welding ribbon without waiting for the welding ribbon clamping mechanism to clamp the welding ribbon. This significantly improves the welding ribbon pulling efficiency.

[0034] In some embodiments, the weld ribbon pulling method further includes: when the first weld ribbon pulling mechanism or the second weld ribbon pulling mechanism pulls the weld ribbon to the transfer station, controlling the weld ribbon transfer mechanism to clamp the end of the weld ribbon located at the transfer station, and pulling the weld ribbon segment to the subsequent station.

[0035] The receiving of the welding ribbon pulled to the transfer station is realized, and the cut welding ribbon segment is automatically transferred to the subsequent station. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] In order to solve the technical problem of low welding ribbon traction efficiency of traditional welding ribbon traction devices, the present invention provides a welding ribbon traction device, which can greatly improve the welding ribbon traction efficiency.

[0046] like Figure 1 and Figure 2 As shown, the welding ribbon pulling device in the embodiment of the present invention includes a cutter mechanism 1, a first welding ribbon pulling mechanism 2 and a second welding ribbon pulling mechanism 3, wherein:

[0047] The first welding ribbon pulling mechanism 2 and the second welding ribbon pulling mechanism 3 are configured to alternately clamp the welding ribbon at the pulling station A located before the cutting station B, and pull the clamped welding ribbon to the transfer station C located after the cutting station B, wherein:

[0048] When the first welding ribbon traction mechanism 2 pulls the clamped welding ribbon to the transfer station C, the second welding ribbon traction mechanism 3 clamps the welding ribbon at the traction station A, and the cutter mechanism 1 cuts the welding ribbon at the cutting station B to obtain a welding ribbon segment with a predetermined length.

[0049] When the second welding ribbon traction mechanism 3 pulls the clamped welding ribbon to the transfer station C, the first welding ribbon traction mechanism 2 clamps the welding ribbon at the traction station A, and the cutter mechanism 1 cuts the welding ribbon at the cutting station B to obtain a welding ribbon segment with a predetermined length.

[0050] In order to enable those skilled in the art to more clearly understand the technical solution of the present invention, the following Figure 1 and Figure 2 , the working process of the welding ribbon pulling device in the embodiment of the present invention is described in more detail.

[0051] Before officially starting the ribbon pulling, it is necessary to pull the free end of the ribbon from the ribbon roll and position it at the pulling station A. Then start the ribbon pulling operation as follows:

[0052] The first welding strip pulling mechanism 2 clamps the free end of the welding strip from the pulling station A and pulls the clamped welding strip to the transfer station C. At the same time, the second welding strip pulling mechanism 3 moves to the pulling station A and clamps the welding strip. Figure 1 As shown, the second welding strip pulling mechanism 3 and the first welding strip pulling mechanism 2 clamp the welding strip from the front and back sides of the cutting station B at the same time.

[0053] The cutter mechanism 1 cuts the welding ribbon at the cutting station B, thereby obtaining a welding ribbon segment. At this time, the new free end of the welding ribbon is clamped in the second welding ribbon pulling mechanism 3.

[0054] Then, the second welding ribbon pulling mechanism 3 pulls the clamped welding ribbon to the transfer station C. At the same time, the first welding ribbon pulling mechanism 2 releases the welding ribbon segment and moves to the pulling station A to clamp the welding ribbon. Figure 2 As shown, the first welding strip pulling mechanism 2 and the second welding strip pulling mechanism 3 clamp the welding strip from the front and back sides of the cutting station B at the same time.

[0055] The cutter mechanism 1 cuts the welding strip at the cutting station B, thereby obtaining another welding strip segment. At this time, the new free end of the welding strip is clamped in the first welding strip pulling mechanism 2.

[0056] By repeatedly performing the above-mentioned pulling and cutting processes, welding ribbon segments can be obtained alternately, and the welding ribbon segments are pulled to the transfer station C.

[0057] Of course, after the free end of the upper welding ribbon is pulled to the pulling station A, the second welding ribbon pulling mechanism 3 may first perform the welding ribbon pulling action.

[0058] As can be seen, in the welding ribbon pulling device of the present invention, the first welding ribbon pulling mechanism 2 and the second welding ribbon pulling mechanism 3 alternately clamp the welding ribbon at the pulling station A in the upstream of the cutter mechanism 1 and pull the welding ribbon to the transfer station C in the downstream. In particular, while one welding ribbon pulling mechanism pulls the previous welding ribbon section to the transfer station C, the other welding ribbon pulling mechanism can simultaneously clamp the next welding ribbon section at the pulling station A without waiting for the cutter mechanism to cut the welding ribbon. Furthermore, because the welding ribbon in the upstream of the cutter mechanism 1 is already clamped by the welding ribbon pulling mechanism at the pulling station A, the cutter mechanism 1 can cut the welding ribbon without waiting for the welding ribbon clamping mechanism to clamp the welding ribbon.

[0059] Compared with the traditional welding ribbon pulling device, the welding ribbon pulling device provided by the embodiment of the present invention greatly improves the pulling efficiency of the welding ribbon and saves the welding ribbon feeding time.

[0060] Continue to refer Figure 1 and Figure 2As shown, optionally, the ribbon traction device in the embodiment of the present invention further includes a ribbon lifting mechanism 4 provided between the cutting station B and the transfer station C. When the first ribbon traction mechanism 2 and the second ribbon traction mechanism 3 pull the ribbon to the transfer station C, the ribbon lifting mechanism 4 is used to lift the ribbon upward, thereby supporting the ribbon and preventing it from falling.

[0061] Optionally, the ribbon lifting mechanism 4 includes a lifting portion and a first lifting drive portion, wherein the lifting portion is connected to the first lifting drive portion, and the first lifting drive portion drives the lifting portion to rise and fall.

[0062] Optionally, a welding strip guide groove is provided on the supporting portion, and the welding strip guide groove is used to guide and position the welding strip to prevent the welding strip from being horizontally offset.

[0063] When the first and second welding ribbon pulling mechanisms 2 and 3 are pulling the welding ribbon, the lifting portion is driven by the first lifting drive unit to descend to a low position, thereby implementing the avoidance of the first and second welding ribbon pulling mechanisms 2 and 3. After the first and second welding ribbon pulling mechanisms 2 and 3 complete the welding ribbon pulling action, the lifting portion is driven by the first lifting drive unit to ascend to a high position to support the welding ribbon.

[0064] As mentioned above, when the first welding ribbon pulling mechanism 2 or the second welding ribbon pulling mechanism 3 pulls the welding ribbon from the pulling station A for the first time, the free end of the welding ribbon needs to be pulled and positioned at the pulling station A.

[0065] In order to position the free end of the welding ribbon at the pulling station A before the first welding ribbon pulling mechanism 2 or the second welding ribbon pulling mechanism 3 performs the first pulling, the welding ribbon pulling device in the embodiment of the present invention optionally further includes a clamping mechanism 5 provided in front of the pulling station A. When the first welding ribbon pulling mechanism 2 or the second welding ribbon pulling mechanism 3 clamps the welding ribbon at the pulling station A for the first time, the clamping mechanism 5 clamps the free end of the welding ribbon, thereby clamping and positioning the free end of the welding ribbon.

[0066] Optionally, the cutter mechanism 1 includes a cutter and a second lifting drive unit, wherein: the cutter is connected to the second lifting drive unit, and the second lifting drive unit is used to drive the cutter to rise and fall.

[0067] When the first and second welding ribbon pulling mechanisms 2 and 3 are pulling the welding ribbon, the cutter is driven by the second lifting drive unit to descend to a low position, thereby avoiding the first and second welding ribbon pulling mechanisms 2 and 3. When the welding ribbon needs to be cut, the cutter is driven by the second lifting drive unit to ascend to a high position, thereby contacting and cutting the welding ribbon.

[0068] Optionally, the ribbon pulling device in the embodiment of the present invention further includes a ribbon transfer mechanism. The ribbon transfer mechanism is used to clamp the ribbon pulled to the transfer station C by the first ribbon pulling mechanism 2 and the second ribbon pulling mechanism 3, and to pull the obtained ribbon segment to the subsequent station D.

[0069] That is, when the first and second ribbon pulling mechanisms 2 and 3 pull the ribbon to the transfer station C, the ribbon transfer mechanism receives and clamps the free end of the ribbon, and then pulls the cut ribbon segment to the subsequent station D. Of course, when the ribbon transfer mechanism clamps the ribbon, the ribbon may not have been cut yet, or it may have been cut.

[0070] Continue to refer Figure 1 and Figure 2 As shown, in order to promptly receive the welding ribbon pulled by the first welding ribbon pulling mechanism 2 and the second welding ribbon pulling mechanism 3 and improve the transfer efficiency, the welding ribbon transfer mechanism optionally includes a third welding ribbon pulling mechanism 6 and a fourth welding ribbon pulling mechanism 7, which alternately clamp the welding ribbon from the transfer station C and pull the welding ribbon segment to the subsequent station D.

[0071] like Figure 3 and Figure 4 As shown, optionally, the welding ribbon pulling device in the embodiment of the present invention further includes a mounting base 8, a first guide rail 9 and a second guide rail 10, wherein:

[0072] The first guide rail 9 and the second guide rail 10 are arranged side by side on the mounting base 8 along the extending direction of the welding strip.

[0073] The first welding tape traction mechanism 2 and the fourth welding tape traction mechanism 7 are slidably mounted on the first guide rail 9. The first welding tape traction mechanism 2 slides along the first guide rail 9 to achieve position switching between the traction station A and the transfer station C. The fourth welding tape traction mechanism 7 slides along the first guide rail 9 to achieve position switching between the transfer station C and the downstream station D. The second welding tape traction mechanism 3 and the third welding tape traction mechanism 6 are slidably mounted on the second guide rail 10. The second welding tape traction mechanism 3 slides along the second guide rail 10 to achieve position switching between the traction station A and the transfer station C. The third welding tape traction mechanism 6 slides along the second guide rail 10 to achieve position switching between the transfer station C and the downstream station D.

[0074] It can be seen that by providing the mounting base 8, the first guide rail 9 and the second guide rail 10, the integration and sliding installation of the first welding ribbon traction mechanism 2, the second welding ribbon traction mechanism 3, the third welding ribbon traction mechanism 6 and the fourth welding ribbon traction mechanism 7 are realized, so that each welding ribbon traction mechanism can be moved and switched between the corresponding target stations to complete the corresponding traction action.

[0075] Optionally, the first welding ribbon traction mechanism 2 , the second welding ribbon traction mechanism 3 , the third welding ribbon traction mechanism 6 and the fourth welding ribbon traction mechanism 7 may adopt the same structure.

[0076] Taking the first welding strip traction mechanism 2 as an example, Figure 5 As shown, it includes a sliding bracket 21, a mounting plate 22, a clamping drive mechanism, a first clamping mechanism and a second clamping mechanism, wherein:

[0077] A sliding bracket 21 is connected to the first guide rail 9 or the second guide rail 10, and a mounting plate 22 is mounted on the sliding bracket 21. The first clamping mechanism includes a first clamping plate slidably mounted on the mounting plate 22 and a plurality of first clamping jaws 23 disposed on the first clamping plate. The second clamping mechanism includes a second clamping plate fixedly mounted on the mounting plate 22 and a plurality of second clamping jaws 24 disposed on the second clamping plate. The first clamping jaws 23 and the second clamping jaws 24 are spaced apart from each other, and adjacent first clamping jaws 23 and second clamping jaws 24 form a set of clamping jaws. Figure 5 In this embodiment, the number of first clamping jaws 23 and second clamping jaws 24 is sixteen, forming a total of sixteen groups of clamping jaws to simultaneously pull sixteen welding ribbons. Of course, other numbers of clamping jaws may also be provided. Generally, the number of clamping jaws provided is equal to the number of welding ribbons included in the group of welding ribbons to be pulled.

[0078] The driving end of the clamping drive mechanism is connected to the first clamping plate, which is used to drive the first clamping plate to translate relative to the second clamping plate, so that the first clamping jaw 23 and the second clamping jaw 24 in each group of clamping jaws are clamped or separated to achieve clamping or release of the corresponding welding strip.

[0079] Welding ribbons are generally divided into two groups: round ribbons and flat ribbons. When the flat ribbon is horizontal, the first and second clamping jaws 23 and 24 directly clamp the ribbon, which can easily cause the ribbon to curl and deform. To address this issue, the clamping surface of the first clamping jaw 23 is optionally provided with a first ribbon clamping groove, and the clamping surface of the second clamping jaw 24 is optionally provided with a second ribbon clamping groove corresponding to the first ribbon clamping groove. When the first and second clamping jaws 23 and 24 clamp the flat ribbon, the flat ribbon enters and is clamped in the first and second ribbon clamping grooves.

[0080] Of course, the first welding tape traction mechanism 2, the second welding tape traction mechanism 3, the third welding tape traction mechanism 6 and the fourth welding tape traction mechanism 7 can also adopt different structures. For example, in some embodiments, the first welding tape traction mechanism 2, the second welding tape traction mechanism 3 adopts Figure 5 As shown in the structure, the third welding strip pulling mechanism 6 and the fourth welding strip pulling mechanism 7 clamp and pull the welding strip by clamping the free end of the welding strip from top to bottom.

[0081] The present invention further provides a welding ribbon pulling method, which can be provided by the welding ribbon pulling device embodiment provided in the above embodiment. The welding ribbon pulling method includes:

[0082] The first welding ribbon pulling mechanism 2 is controlled to clamp the welding ribbon at the pulling station A located before the cutting station B, and the clamped welding ribbon is pulled to the transfer station C located after the cutting station B.

[0083] The second welding ribbon pulling mechanism 3 is controlled to clamp the welding ribbon at the pulling station A when the first welding ribbon pulling mechanism 2 pulls the welding ribbon to the transfer station C.

[0084] The cutter mechanism 1 is controlled to cut the welding ribbon at the cutting station B to obtain a welding ribbon segment with a predetermined length.

[0085] The second welding ribbon pulling mechanism 3 is controlled to pull the clamped welding ribbon to the transfer station C.

[0086] When the second welding ribbon pulling mechanism 3 pulls the welding ribbon to the transfer station C, the first welding ribbon pulling mechanism 2 is controlled to clamp the welding ribbon at the pulling station A to pull the next section of welding ribbon.

[0087] Optionally, the weld ribbon pulling method in an embodiment of the present invention further includes: when the first weld ribbon pulling mechanism 2 or the second weld ribbon pulling mechanism 3 pulls the weld ribbon to the transfer station C, controlling the weld ribbon transfer mechanism to clamp the end of the weld ribbon located at the transfer station C, and pulling the weld ribbon segment to the subsequent station D.

[0088] The present invention has been described above in sufficient detail with certain particularities. Those skilled in the art will appreciate that the descriptions in the embodiments are merely illustrative, and that all modifications that do not depart from the true spirit and scope of the invention are intended to be within the scope of protection of the present invention.
