Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell production equipment, and specifically to a busbar preparation station and preparation device. Background Art

[0002] Solar cell modules convert solar energy into electricity and are becoming increasingly common. During the production of solar cell modules, there's a process called busbar welding, which involves welding the busbars to the extended ribbons at both ends and the middle of the cell string.

[0003] Before performing busbar welding, the busbar needs to be placed on a busbar preparation table and processed to obtain the busbar required for welding.

[0004] The busbar preparation table includes a support platform and a clamping mechanism. Before the busbar is processed, the clamping mechanism presses the busbar against the support platform. The clamping mechanism of existing busbar preparation tables mainly includes a clamping drive and a pressure plate. The clamping drive drives the pressure plate to rotate and press downward toward the support platform, thereby driving the pressure plate to press the busbar located on the support platform. A problem with existing busbar preparation tables is that when the clamping end of the pressure plate is not horizontal after rotation or the support platform is not horizontal, the pressure plate cannot firmly press the busbar against the support platform when it rotates and presses downward, thereby affecting the busbar processing effect.

[0009] The busbar preparation table of the present application, when the clamping drive drives the pressure plate to rotate and press down from the side of the carrier table toward the carrier table, the pressure block presses the busbar on the carrier table. Since the pressure block is rotatably connected to the upper end of the pressure plate, the pressure block can adaptively adjust the clamping angle when it contacts the busbar. In this way, even if the bearing surface of the carrier table is not horizontal, the pressure block can adaptively rotate until it is parallel or close to parallel with the bearing surface, thereby ensuring that the busbar is pressed on the carrier table.

[0047] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] like Figures 1 to 3 As shown, the busbar preparation station in the embodiment of the present application includes at least one carrier 1 and a pressing mechanism 2 provided in a one-to-one correspondence with the carrier 1. For example, the busbar preparation station shown in the figure includes three carriers 1, and each carrier 1 is provided with a pressing mechanism 2.

[0049] The supporting platform 1 is used for supporting the busbar extending along a first horizontal direction (eg, X-axis direction).

[0050] The clamping mechanism 2 includes a clamping drive 21, a pressure plate 22 and a pressure block 23, wherein the pressure block 23 is rotatably connected to the upper end of the pressure plate 22, and the clamping drive 21 is configured to drive the pressure plate 22 to rotate and press down from the side of the carrier platform 1 toward the carrier platform 1, so as to drive the pressure block 23 to clamp the bus bar on the carrier platform 1.

[0051] It can be seen that in the busbar preparation table implemented in the present application, when the clamping drive 21 drives the pressure plate 22 to rotate and press down from the side of the carrier platform 1 toward the carrier platform 1, the busbar is pressed on the carrier platform 1 by the pressure block 23 connected to the upper end of the pressure plate 22. Since the pressure block 23 is rotatably connected to the upper end of the pressure plate 22, if the pressure-bearing surface of the carrier platform 1 is not horizontal, the pressure block 23 will produce adaptive rotation due to uneven pressure after contacting the busbar, thereby ensuring that the pressure block 23 can press the busbar on the carrier platform 1.

[0052] Optionally, the middle portion of the pressure plate 22 is hinged to the carrier platform 1, and the lower end of the pressure plate 22 is hinged to the driving end of the clamping driver 21. When the clamping driver 21 drives the pressure plate 22 upward, the upper end of the pressure plate 22 rotates downward toward the carrier platform 1, thereby clamping the busbar on the carrier platform 1. When the clamping driver 21 drives the pressure plate 22 downward, the upper end of the pressure plate 22 rotates away from the carrier platform to release the busbar.

[0053] The pressing drive member 21 may be, for example, a cylinder. The lower end of the pressing plate 22 is hinged to the telescopic rod of the cylinder. The cylinder drives the pressing plate 22 by controlling the telescopic rod to extend and retract up and down.

[0054] like Figure 3 As shown, in order to achieve the rotational connection between the pressure block 23 and the upper end of the pressure plate 22, optionally, the upper end of the pressure plate 22 is provided with an axial hole extending along the first horizontal direction, and the clamping mechanism 2 also includes a rotating shaft 24 arranged in the axial hole, and the pressure block 23 is connected to the rotating shaft 24 and can rotate around the rotating shaft 24.

[0055] Optionally, the upper end of the pressure plate 22 is further provided with a mounting groove connected to the shaft hole, and the back of the pressure block 23 is provided with a connecting block 25. The connecting block 25 is inserted into the mounting groove and connected to the rotating shaft 24. The connecting block 25 can rotate around the rotating shaft 24. The mounting groove and the connecting block 25 cooperate with each other to realize the rotation guidance of the pressure block 23, ensuring that the pressure block 23 can be pressed more stably on the supporting platform 1.

[0056] As known to those skilled in the art, in order to enable the junction box to be installed on the battery string group, the busbar welded to the middle of the battery string group is a busbar with bent ends. The bent busbar includes an L-shaped busbar with one end bent and a U-shaped busbar with both ends bent.

[0057] Figure 6 A commonly used battery string group is shown, which includes six assembly units: a first assembly unit PA1-PB1 consisting of battery string PA1 and battery string PB1, a second assembly unit PA2-PB2 consisting of battery string PA2 and battery string PB2, a third assembly unit PA3-PB3 consisting of battery string PA3 and battery string PB3, a fourth assembly unit PA4-PB4 consisting of battery string PA4 and battery string PB4, a fifth assembly unit PA5-PB5 consisting of battery string PA5 and battery string PB5, and a sixth assembly unit PA6-PB6 consisting of battery string PA6 and battery string PB6. Each assembly unit forms a battery string group with 6 groups of 12 strings.

[0058] There are four busbars with bent ends in the middle of the battery string group, namely busbar M1, busbar M2, busbar M3 and busbar M4, among which: busbar M1 is used to weld battery string PA1 and battery string PB1, busbar M2 is used to weld battery string PA2 and battery string PB2, battery string PA3 and battery string PB3, busbar M3 is used to weld battery string PA4 and battery string PB4, battery string PA5 and battery string PB5, and busbar M4 is used to weld battery string PA6 and battery string PB6.

[0059] like Figure 7 As shown, busbar M1 and busbar M4 are shorter L-shaped busbars, wherein the second end (e.g., the left end) of busbar M1 is bent, and the first end (e.g., the right end) of busbar M4 is bent. Busbar M2 and busbar M3 are longer U-shaped busbars with both ends bent.

[0060] The traditional busbar preparation station can simultaneously prepare busbar M1, busbar M2, busbar M3 and busbar M4. Since busbar M1, busbar M2, busbar M3 and busbar M4 have a total of six bending parts, it needs to be equipped with six supporting platforms, six clamping mechanisms and six bending parts. The equipment cost of the traditional busbar preparation station is high and it occupies a large space.

[0061] like Figures 1 to 2 As shown, optionally, the busbar preparation station in the embodiment of the present application includes three supporting platforms 1. In addition, the busbar preparation station also includes a first bending member 3, a second bending member 4 and a third bending member 5, wherein: the first supporting platform 1a, the second supporting platform 1b and the third supporting platform 1c are arranged at intervals along the first horizontal direction. The first bending member 3 and the second bending member 4 are arranged between the first supporting platform 1a and the second supporting platform 1b, the first bending member 3 is configured to bend upward the first end (for example, the right end) of the busbar located on the first supporting platform 1a, and the second bending member 4 is configured to bend upward the second end (for example, the left end) of the busbar located on the second supporting platform 1b. The third bending member 5 is located on the outside of the third supporting platform 1c, and the third bending member 5 is configured to bend upward the first end (for example, the right end) of the busbar located on the third supporting platform 1c.

[0062] By configuring the busbar preparation station in the embodiment of the present application as described above, the station can prepare both L-shaped and U-shaped busbars, and can simultaneously prepare an L-shaped busbar and a U-shaped busbar. This allows the preparation of the intermediate busbar groups required for a battery string to be completed in batches. Compared to conventional busbar preparation stations, the busbar preparation station in the embodiment of the present application reduces equipment costs and space requirements.

[0063] In order to enable those skilled in the art to more clearly understand the working process of the busbar preparation station in the embodiment of the present application, the following will be Figure 7 Take the busbar group to be prepared as an example, combined with Figure 8 The detailed preparation process of the intermediate bus bar group required for the battery string group by the bus bar preparation station in the embodiment of the present application is exemplarily described.

[0064] like Figure 8 As shown in (a) of FIG, a busbar of a first length is placed on the second carrier 1b, ensuring that the second end (e.g., the left end) of the busbar extends outward from the second carrier 1b. Next, the clamping mechanism 2 of the second carrier 1b is controlled to clamp the busbar onto the second carrier 1b. Finally, the second bending member 4 is controlled to bend the second end (e.g., the left end) of the busbar upward, thereby forming an L-shaped busbar M1.

[0065] like Figure 8 As shown in (b), a busbar with a second length is placed on the second carrier 1b and the third carrier 1c, and it is ensured that the second end (e.g., the left end) of the busbar extends outward from the second carrier 1b, and the first end (e.g., the right end) of the busbar extends outward from the third carrier 1c, wherein the second length is longer than the first length. Then, the clamping mechanism 2 of the second carrier 1b and the clamping mechanism 2 of the third carrier 1c are controlled to press the busbar onto the second carrier 1b and the third carrier 1c, respectively. Finally, the second bending member 4 is controlled to bend upward the second end (e.g., the left end) of the busbar on the second carrier 1b, and the third bending member 5 is controlled to bend upward the first end (e.g., the right end) of the busbar on the third carrier 1c, thereby obtaining a U-shaped busbar M2.

[0066] like Figure 8As shown in (c), the busbar with the second length is placed on the second carrier 1b and the third carrier 1c, and it is ensured that the second end (for example, the left end) of the busbar with the second length extends outward from the second carrier 1b, and the first end (for example, the right end) of the busbar with the second length extends outward from the third carrier 1c. At the same time, the busbar with the first length is placed on the first carrier 1a, and it is ensured that the first end (for example, the right end) of the busbar with the first length extends outward from the first carrier 1a. Then, the clamping mechanism 2 of the second carrier 1b and the clamping mechanism 2 of the third carrier 1c are controlled to press the busbar with the second length onto the second carrier 1b and the third carrier 1c, respectively. At the same time, the clamping mechanism 2 of the first carrier 1a is controlled to press the busbar with the first length onto the first carrier 1a. Finally, the second bending member 4 is controlled to bend the second end (e.g., the left end) of the second length busbar upward, and the third bending member 5 is controlled to bend the first end (e.g., the right end) of the second length busbar upward, thereby obtaining a U-shaped busbar M3. Simultaneously, the first bending member 3 is controlled to bend the first end (e.g., the right end) of the first length busbar upward, thereby obtaining an L-shaped busbar M4.

[0067] So far, it is completed Figure 7 Preparation of busbar groups shown.

[0068] Continue to refer Figures 1 to 2 As shown, optionally, the busbar preparation station in the embodiment of the present application also includes a first bending drive member 6 and a second bending drive member 7, wherein: the first bending member 3 and the second bending member 4 are connected side by side on the driving end of the first bending drive member 6 along the first horizontal direction.

[0069] The first bending drive 6 is configured to synchronously drive the first bending member 3 and the second bending member 4 to rise, so that the first bending member 3 bends the first end of the busbar located on the first support platform 1a upward, and the second bending member 4 bends the second end of the busbar located on the second support platform 1b upward. The first bending drive 6 achieves synchronous lifting and lowering of the first bending member 3 and the second bending member 4, so that the first bending member 3 and the second bending member 4 perform the busbar bending operation separately, reducing equipment costs.

[0070] The third bending member 5 is connected to the driving end of the second bending driving member 7. The second bending driving member 7 is configured to drive the third bending member 5 to rise so that the third bending member 5 bends the first end of the busbar on the third supporting platform 1c upward.

[0071] The first bending driving member 6 and the second bending driving member 7 can both adopt various existing lifting driving members, such as cylinders.

[0072] Optionally, the first bending member 3, the second bending member 4 and the third bending member 5 have the same structure. Figures 1 to 2 As shown, the first bending member 3, the second bending member 4 and the third bending member 5 are all rollers.

[0073] In other embodiments, the first bending member 3, the second bending member 4 and the third bending member 5 may also be bending blocks. Taking the first bending member 3 as an example, Figure 4 As shown, the first bending member 3 is a bending block with an arc-shaped bending surface 31 formed on the top. When the first bending member 3 bends the first end (for example, the right end) of the busbar located on the first supporting platform 1a upward, a busbar with a vertical bending end can be obtained.

[0074] like Figure 5 As shown, the first bending piece 3 is a bending block with an inclined bending surface 31 formed on the top. When the first bending piece 3 bends the first end (for example, the right end) of the busbar located on the first supporting platform 1a upward, a busbar with an inclined bending end can be obtained.

[0075] like Figures 1 to 2 As shown, optionally, the busbar preparation station in the embodiment of the present application further includes a first lifting drive 8 for driving the first carrier platform 1 a to move up and down, and a second lifting drive 9 for driving the second carrier platform 1 b to move up and down.

[0076] After the busbar pulling mechanism pulls the busbar of the first length to the top of the first supporting platform 1a, the first lifting drive member 8 drives the first supporting platform 1a to rise to receive the busbar released by the busbar pulling mechanism. This can avoid the busbar from falling too far, causing the busbar to flip or deflect when it falls on the first supporting platform 1a.

[0077] Similarly, after the busbar traction mechanism pulls the busbar of the first length to the top of the second supporting platform 1b, the first lifting drive member 8 drives the second supporting platform 1b to rise to receive the busbar released by the busbar traction mechanism. This can avoid the busbar from falling too far, causing the busbar to flip or deflect when it falls onto the second supporting platform 1b.

[0078] When the busbar traction mechanism pulls the busbar of the second length to the top of the second carrier 1b and the third carrier 1c, since the second half of the busbar can fall onto the third carrier 1c first, the third carrier 1c can already impose a certain limit on the busbar. Therefore, even if the busbar traction mechanism releases the end of the busbar, the busbar will not flip or shift after falling. Therefore, when preparing the busbar of the second length, the second carrier 1b and the third carrier 1c do not need to rise to connect the materials.

[0079] Optionally, at least one pair of limiting pins 10 for limiting the busbar is provided on the first supporting platform 1a, the second supporting platform 1b and the third supporting platform 1c along the first horizontal direction, and the busbar is located between the two limiting pins 10 in the pair.

[0080] To ensure that the clamping mechanism 2 corresponding to the first carrier 1a can be raised and lowered synchronously with the first carrier 1a, the clamping mechanism 2 corresponding to the first carrier 1a is optionally connected to the driving end of the first lifting drive 8. Similarly, the clamping mechanism 2 corresponding to the second carrier 1b is connected to the driving end of the second lifting drive 9.

[0081] The present application also provides a busbar preparation device comprising a supply mechanism, a traction mechanism, and the busbar preparation table described in any of the above embodiments. The supply mechanism is configured to supply busbars, and the traction mechanism is configured to traction the busbars supplied by the supply mechanism onto the busbar preparation table. Through the coordination of the supply mechanism, traction mechanism, and busbar preparation table, the busbar preparation device enables automatic busbar preparation and loading and unloading, thereby improving busbar preparation efficiency.

[0082] Optionally, the supply mechanism includes an unwinding portion, a pressing portion, and a cutting portion, arranged in sequence, wherein the unwinding portion is used to unwind the busbar, and the pulling mechanism is configured to clamp the free end of the busbar from the cutting portion and pull the busbar passing through the pressing portion and the cutting portion in a first horizontal direction away from the cutting portion; when the busbar of a predetermined length is pulled out of the cutting portion, the cutting portion is configured to cut the busbar, and the pressing portion is configured to press the busbar while the cutting portion cuts the busbar. Through the cooperation of the unwinding portion, the pressing portion, and the cutting portion, the supply mechanism automatically supplies the busbar of a predetermined length.

[0083] The above description of the present application is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and that all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the above description in the embodiments. Furthermore, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
