Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component manufacturing, and particularly relates to a busbar preparation module and busbar placement equipment. Background Art

[0002] The manufacturing process of photovoltaic modules often requires the cutting, placement, and fixing of busbars. Prior to cutting, the busbars are typically strips wrapped around a carrier tray. They are then pulled to a predetermined length, cut, and slit into corresponding lengths. After adjusting the length and handling, they are then positioned in the corresponding positions of the battery module and fixed by heat fusion.

[0003] Currently, during the busbar cutting process, the cutting mechanism typically needs to avoid the busbar material during the loading process. Therefore, the cutting mechanism needs to be equipped with at least two power sources to achieve the horizontal displacement during the avoidance process and the vertical displacement during the cutting process. This approach results in a complex power mechanism for the equipment, which is difficult to set up and occupies a large space. Moreover, the cutting force required by the existing cutting mechanism is often directly provided by the drive mechanism, and the output force of the drive mechanism is not amplified. This poses a risk of material not being cut, affecting the efficiency and accuracy of busbar cutting. Utility Model Content

[0047] Example:

[0048] In a preferred embodiment of the present invention, a busbar preparation module 200 is proposed, which is intended to carry out the cutting and preparation process of the busbar material after loading, and cut and make the uncut material (busbar) into a busbar 400 that can match the battery assembly.

[0049] In a preferred embodiment, the busbar preparation module 200 includes at least one cutting mechanism 4, which is as follows: Figure 1 、 Figure 2 As shown in the figure, it includes a first cutter 410 and a second cutter 411 arranged in pairs, and a displacement component arranged corresponding to the two cutters; the displacement component is used to drive the two cutters to move closer to or farther away from the material, and to achieve relative drive between the two cutters, thereby completing the cutting process of the two cutters.

[0050] In actual configuration, considering that the cutting mechanism 4 needs to avoid the pulling mechanism when the material is being loaded, the two cutters of the cutting mechanism 4 avoid the pulling mechanism when the material is pulled out and loaded by the pulling mechanism, and are first located on the side of the pulling path of the pulling mechanism. After the material is loaded and pulled out to the required length, they move closer to the material so that the material is located between the first cutter 410 and the second cutter 411. Then, the relative displacement between the two cutters is controlled to achieve the cutting process of the material. Therefore, in actual configuration, the displacement component set for the two cutters preferably includes two movement processes, namely, the horizontal movement of the two cutters to approach the material and the vertical movement cutting process.

[0051] In a preferred embodiment, the displacement assembly includes a driving unit 404, a cutting chute block 405, a coupling guide block 402, and a cutting limit block 409. One end of the cutting chute block 405 is connected to the output shaft end of the driving unit 404, and can be driven by the driving unit 404 to perform horizontal reciprocating displacement, that is, to perform the following operations: Figure 1 Reciprocating movement in the X-axis direction.

[0052] At the same time, the cutting chute block 405 is relative to the output shaft axis of the driving unit 404 (i.e. Figure 1 A beveled slot 4051 is provided diagonally upward (in the X-axis direction shown in FIG) toward the side away from the output shaft. This slot 4051 facilitates vertical relative displacement between the two cutters during the horizontal movement of the cutting chute block 405. Furthermore, the output force of the drive unit 404 is amplified by the slot 4051, improving cutting stability.

[0053] In more detail, the coupling guide block 402 in the preferred embodiment is provided with a cavity for the cutting chute block 405 to pass through, and a guide rod 407 capable of vertical lifting is provided corresponding to the coupling guide block 402, that is, Figure 1 The reciprocating motion in the Z-axis direction is shown in FIG.

[0054] In detail, the guide rod 407 is movably connected to the cutting chute block 405 through a sliding sleeve 408 passing through the inclined groove 4051. The horizontal movement of the cutting chute block 405 relative to the coupling guide block 402 can be converted into the displacement movement of the sliding sleeve 408 in the inclined groove 4051 and the vertical lifting movement of the guide rod 407 relative to the coupling guide block 402.

[0055] The first cutter 410 is arranged on the top of the guide rod 407, and the second cutter 411 is arranged on the top of the coupling guide block 402. The relative displacement between the two cutters is achieved by the movement of the guide rod 407 relative to the coupling guide block 402.

[0056] In addition, the cutting limit block 409 is arranged at intervals on one side of the coupling guide block 402, and is used to limit the coupling guide block 402 after the horizontal movement is in place; and the cutting chute block 405 can continue to be driven forward by the driving unit 404 after the coupling guide block 402 is limited, and drive the guide rod 407 and the first cutter 410 on the top of the guide rod 407 to descend, realizing the coordinated cutting of the first cutter 410 and the second cutter 411, completing the cutting operation of the material, and obtaining the cut bus bar 400.

[0057] It can be understood that for the cutting limit block 409 in the preferred embodiment, it is preferably vertically aligned with the material to be cut after loading. Such a setting can ensure that when the coupling guide block 402 abuts the cutting limit block 409, the two cutters just move horizontally to the position of the material to be cut.

[0058] In more detail, the displacement assembly in the preferred embodiment further includes a fixed mounting seat 403 and a guide slide 401 connected to one side of the fixed mounting seat 403 .

[0059] In actual setting, the driving unit 404 is connected to the side of the fixed mounting base 403 away from the guide slide 401, that is, the three are arranged in sequence in the X-axis direction. At the same time, the coupling guide block 402 is slidably arranged relative to the guide slide 401, and the sliding direction is the direction in which the driving unit 404 drives the cutting chute block 405 to move, that is, the coupling guide block 402 moves along the inner side of the guide slide 401. Figure 1 The X-axis direction is set, and the cutting limit block 409 is installed on the side of the guide slide 401 away from the fixed mounting seat 403, as shown Figure 1 As shown in .

[0060] For example, in the preferred embodiment, the specific form of the sliding arrangement of the coupling guide block 402 along the X-axis direction in the guide slide 401 is: a slide groove is opened on the guide slide 401, and a slider is provided at the bottom of the coupling guide block 402, and the sliding connection between the coupling guide block 402 and the guide slide 401 is realized by utilizing the sliding matching of the slide groove in the slide groove.

[0061] In more detail, the driving unit 404 in the preferred embodiment is a cylinder connected to the fixed mounting base 403.

[0062] Further preferably, a limiting groove is opened on the guide slide 401 corresponding to the bottom of the guide rod 407, which can be aligned with the bottom of the guide rod 407 when the coupling guide block 402 abuts the cutting limit block 409, and the guide rod 407 can be embedded in the limiting groove with its end after vertical movement.

[0063] For example, the guide rods 407 in the preferred embodiment are arranged in pairs or are a "door"-shaped structure including two guide rods 407, and a pair of sliding assembly holes are vertically opened on the coupling guide block 402; accordingly, the cutting slide block 405 is passed through the two guide rods 407 to save space, and the middle part of the sliding sleeve 408 is passed through the inclined groove 4051, and the two ends of the sliding sleeve 408 are respectively connected to the middle parts of the two guide rods 407, as shown in FIG. Figure 2 At this time, the limiting grooves provided on the guide slide 401 are preferably two provided in pairs.

[0064] In more detail, during actual assembly, an elastic member 406 is preferably provided between the coupling guide block 402 and the fixed mounting seat 403, for always applying a force to the coupling guide block 402, and always controlling the sliding sleeve 408 at the top position of the inclined groove 4051 before the coupling guide block 402 abuts the cutting limit block 409.

[0065] It is understandable that, in addition to providing the elastic member 406 to lock the position of the sliding sleeve 408 in the inclined groove 4051 , this can also be achieved by providing a combination of the length of the guide rod 407 and the limiting groove.

[0066] That is, by optimally designing the length of the guide rod 407, before the coupling guide block 402 abuts the cutting stop block 409, the bottom of the guide rod 407 abuts the surface of the guide slide 401. That is, at this time, the bottom of the guide rod 407 is in sliding contact with the guide slide 401, and the sliding sleeve 408 is located at the top of the inclined groove 4051. Thereafter, when the coupling guide block 402 moves to the cutting stop block 409, the guide rod 407 is vertically aligned with the limit groove. Under the action of the guide rod 407's own weight and the driving force generated by the continued movement of the cutting slide block 405, the guide rod 407 gradually descends, causing the sliding sleeve 408 to move in the inclined groove 4051, ultimately completing the matching cutting of the two cutters.

[0067] The busbar preparation module of the present invention further improves the accuracy of the displacement motion control of the two cutters and ensures the accuracy of the cutting position of the busbar material by optimally arranging structures such as a fixed mounting seat, a guide slide, an elastic member, a pulling mechanism, a bending mechanism, and a pressing mechanism.

[0068] Furthermore, the cutting mechanism in the preferred embodiment can cut the cutting edge of the material into an arc shape during cutting. Specifically, the first cutter 410 is an arc cutter including an arc line, and its outer contour is an hourglass shape, such as Figure 3 As shown in .

[0069] Correspondingly, a cutting hole corresponding to the outer contour of the first cutter 410 is formed on the second cutter 411, so that the first cutter 410 can complete the cutting of the material by vertically embedding into the cutting hole.

[0070] For example, in order to ensure the accurate alignment of the two cutters during actual control, in actual setting, it is preferred to provide a slide groove vertically on one side of the cutting hole, and provide a slider on the first cutter 410. By sliding the slider on the first cutter 410 and the slide groove on the second cutter 411, it can be ensured that the cutting edge of the first cutter 410 is always vertically aligned with the cutting hole.

[0071] For the arc cutter in the preferred embodiment, due to the preferred design of the cutter form, the end form of the busbar 400 obtained is different from that of the conventional straight cutter, such as Figure 4 As shown in . After being cut by a conventional straight cutter, the ends of the busbar 400 (a) are straight, and there is no waste material between the two busbars 400 (a); while for the middle arc cutter in the preferred embodiment, the ends of the two busbars 400 (b) after being cut are both in the form of arcs. In this case, there is an hourglass-shaped waste material between the two arcs, as shown in . Figure 4 As shown in , the waste will fall below the cutout hole.

[0072] By setting the two cutters of the cutting mechanism into an arc shape, the cross section of the busbar is cut into an arc, which is convenient for the subsequent installation of the junction box; and further designing the first cutter 410 into an hourglass shape, it can cut both sides of the cross section into arcs with one cut, thereby improving the cutting efficiency.

[0073] In a preferred embodiment, to facilitate waste collection, a waste channel 413 is preferably provided below the cutting hole, and a waste box 412 is provided at the outlet of the waste channel 413, so that waste cut by the two arc cutters can be collected in the waste box 412 via the waste channel 413. The combination of the waste channel and the waste box facilitates the collection of waste generated after busbar cutting into the waste box, thus avoiding the adverse effects of waste cleaning.

[0074] Furthermore, the busbar preparation module 200 in the preferred embodiment further includes a carrying platform 1 and a material pulling mechanism 6 provided corresponding to the carrying platform 1;

[0075] In actual setting, the cutting mechanism 4 is arranged in the width direction of the carrier 1 (ie Figure 5 The support platform 1 is provided with a clearance notch on the side of the support platform 1 facing the cutting mechanism 4. Driven by the displacement assembly, the two cutters of the cutting mechanism 4 can move horizontally to the clearance notch and complete the cutting of the material at the clearance notch.

[0076] At the same time, the pulling mechanism 6 is preferably arranged above the cutting mechanism 4 to pull and feed the busbar material to be cut onto the carrying platform 1 .

[0077] In order to ensure that the position of the busbar material is reliably maintained after it is fed onto the carrier platform 1 , a pressing mechanism 2 is preferably provided above the carrier platform 1 for pressing the material fed onto the carrier platform 1 .

[0078] In actual setting, the pressing mechanism 2 is preferably in the direction of material extension ( Figure 5 Multiple ones are arranged at intervals in the Y-axis direction shown in .

[0079] More preferably, in the preferred embodiment, the cutting mechanisms 4 corresponding to the carrier platform 1 are multiple and spaced apart, such as Figure 5 correspondingly, the pressing mechanism 2 and the cutting mechanism 4 are arranged in a one-to-one correspondence, and are also arranged in multiples at intervals.

[0080] In more detail, a bending mechanism 5 is provided corresponding to each cutting mechanism 4 , which is provided at the avoidance notch of the supporting platform 1 for bending the ends of the cut material, thereby achieving the bending operation of the ends of the busbar 400 after cutting.

[0081] Furthermore, the bending mechanism 5 and the pressing mechanism 2 in the preferred embodiment are integrated into a bending and pressing assembly, such as Figure 6 At this time, the bending and pressing assembly includes a mounting frame 501 and a bending block 502, and the bending block 502 is mounted on the mounting frame 501 via a pressing drive 503 and a bending drive 504 that are matched with each other. The bending drive 504 is a rotary drive, and the bending block 502 is connected to the rotary drive, so that the bending block 502 can complete the bending of the end of the cut busbar 400 by rotation. The pressing drive 503 is a translation drive, and the bending drive 504 is assembled on the pressing drive 503. The lifting and lowering movement of the pressing drive 503 can drive the bending block 502 to move vertically, thereby driving the bending block 502 to move closer to or away from the material, completing the compression or release of the material.

[0082] It is easy to understand that the aforementioned bending block 502 can be used as a pressing block for the material before cutting, and can complete the bending function by rotating after cutting is completed.

[0083] Furthermore, in actual configuration, in order to cut the ends of the busbar material during feeding, a straight cutter mechanism 3 is provided at one end of the carrier 1 for cutting the material pulled from the tray into a certain length.

[0084] Furthermore, as another aspect of the present invention, a busbar placement device is preferably provided, which includes a busbar preparation module 200 and a battery assembly conveying module; and

[0085] The busbar preparation module 200 further includes a busbar feeding mechanism 100 and a busbar variable distance transport mechanism 300. The busbar feeding mechanism 100 is disposed at one end of the busbar preparation module 200 and is used to provide materials to be cut and placed.

[0086] At the same time, the battery assembly conveying module is arranged below the cutting mechanism 4 for conveying the battery assembly, and the busbar variable distance conveying mechanism 300 is arranged on one side of the cutting mechanism 4 for conveying the prepared busbar 400 to the battery assembly on the battery assembly conveying module to complete the placement of the busbar 400.

[0087] By setting up a combination of a battery assembly conveying module and a busbar preparation module 200, the prepared busbar 400 can be accurately transported to the fed battery assembly through the busbar variable-distance transport mechanism 300, accurately realizing the busbar preparation process, transport process and placement process, thereby improving the efficiency and accuracy of busbar processing, and thereby improving the efficiency and accuracy of battery assembly processing.

[0088] For the busbar placement device having the busbar preparation module 200 in the preferred embodiment, the working process in actual use is preferably as follows:

[0089] Before feeding the busbar material, the driving unit 404 of each cutting mechanism 4 controls the cutting chute block 405 to the initial position. At this time, the coupling guide block 402 is away from the cutting limit block 409, and the two cutters are vertically spaced from each other. In this way, the feeding of the busbar material can be ensured without interference from the cutting mechanisms 4.

[0090] Afterwards, the pulling mechanism 6 is controlled to clamp the end of the busbar material on the material tray from the busbar feeding mechanism 100, and pull the busbar material onto the supporting platform 1 along the Y-axis direction shown in the figure; when the material is pulled into place, the pressing mechanism 2 is controlled to press the material on the supporting platform 1, and the straight cutting knife mechanism 3 is controlled to cut the material. At this time, a long section of material that can be used to prepare multiple busbars is obtained.

[0091] Afterwards, the displacement components of each cutting mechanism 4 are controlled to work, and the driving unit 404 drives each cutting chute block 405 and the coupling guide block 402 to move along the X-axis direction shown in the figure, and controls the two cutters to approach the busbar material pressed on the supporting platform 1 in the horizontal direction; the coupling guide block 402 abuts the cutting limit block 409, at this time, the two cutters of each cutting mechanism 4 move horizontally to the upper and lower sides of the material respectively; continue to control the cutting chute block 405 to move relative to the coupling guide block 402, at this time, the sliding sleeve 408 connected to the guide rod 407 moves from the top to the bottom in the inclined groove 4051, thereby driving the first cutter 410 to move downward, and continuously approaching the second cutter 411, until the first cutter 410 is embedded in the cutting hole on the second cutter 411, and the busbar material is cut into multiple sections.

[0092] Accordingly, the waste generated by cutting is collected into the waste box 412 via the waste channel 413 .

[0093] After cutting is completed, each driving unit 404 is controlled to move in the opposite direction, first driving the sleeve 408 to move upward in the inclined groove 4051, driving the bottom of the guide rod 407 to extend from the limit groove until the sleeve 408 moves to the top of the inclined groove 4051, after which the coupling guide block 402 and the cutting slide block 405 are driven together by the driving unit 404.

[0094] After the cutting mechanism 4 is reset, the bending mechanism 5 is controlled to work and bend the two ends of the cut busbar 400; thereafter, the clamping mechanism 2 and the bending mechanism 5 are released from the effects of the busbar 400, and the busbar variable-pitch conveying mechanism 300 is controlled to convey the prepared busbar 400 and convey it to the battery assembly fed to the bottom of the cutting mechanism 4, thereby completing the busbar cutting, preparation, conveying and placement process.

[0095] The busbar preparation module in the utility model has a compact structure and is easy to use. It can effectively simplify the structural design of the driving process required in the busbar preparation process, ensure the size of the cutting force, improve the accuracy of busbar cutting, and reduce the cost of busbar processing and application, and has good practical value.
