[0037] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0039] An embodiment of the present application provides a busbar hot pressing reflow line. Figure 2This is a schematic diagram of the top view layout of a busbar hot pressing return line provided in an embodiment of the present application. Figure 2 As shown, the busbar hot pressing reflow line 000 includes: a conveying track 100, a feeding conveying platform 210, a discharging conveying platform 220 and a pressing device 300.

[0040] The conveying track 100 has a preset conveying direction. Along the preset conveying direction, the feed conveying platform 210 is arranged downstream of the conveying track 100, and the discharge conveying platform 220 is arranged upstream of the conveying track 100. A work station for busbar assembly is provided on the conveying track 100; the pressing device 300 is arranged between the feed conveying platform 210 and the discharge conveying platform 220; after the busbar assembly is completed on the conveying track 100, the mold is transferred to the feed conveying platform 210, and is transferred to the pressing device 300 for pressing via the feed conveying platform 210, and is transferred to the discharge conveying platform 220 after pressing is completed; wherein, the pressing device 300 includes at least two layers of openings for carrying the mold that has completed the busbar assembly, so as to press at least two layers of molds at the same time.

[0041] Specifically, during the production process, the conveying track 100 conveys the mold in a preset conveying direction. For example, the preset conveying direction can be clockwise or counterclockwise, which is not limited here. Figure 2 The arrows in the table indicate that Figure 2 The figure shows the case where the preset conveying direction is clockwise. The feed conveyor 210 is positioned downstream of the conveyor track 100 along the preset conveying direction, allowing molds that have completed busbar assembly on the conveyor track 100 to be transferred to the feed conveyor 210. The molds that have completed busbar assembly are transferred from the feed conveyor 210 to the pressing equipment 300 for the mold pressing operation. After the pressing operation is completed, the molds are transferred from the pressing equipment 300 to the discharge conveyor 220, thus completing a single production run of the mold. If the mold needs to continue production, it is transferred from the discharge conveyor 220 to the conveyor track 100 for the busbar assembly operation, entering a new production cycle.

[0042] Since the laminating device 300 includes at least two layers of openings, each layer of openings can accommodate a mold. Therefore, at least two molds can be placed in the laminating device 300 at one time. In this way, at least two molds can be pressed simultaneously in one pressing process. For example, the pressing time is approximately 60 to 90 minutes. That is, a larger number of molds can be pressed within the same pressing time. Moreover, each additional layer of openings in the laminating device 300 can double the production efficiency compared to a single-layer pressing device. Therefore, the busbar pressing return line provided in the embodiment of the present application is conducive to improving product production efficiency and is suitable for mass production of products.

[0043] It should be noted that Figure 2FIG3 is a top view of a busbar hot pressing reflow line, and the at least two layers of openings included in the pressing device 300 are stacked in a direction perpendicular to the paper surface. Therefore, Figure 2 The lamination device 300 has multiple layers of openings that are not shown.

[0044] Compared with the single-layer pressing equipment used in the related art, the embodiment of the present application adopts a pressing device 300 with at least two layers of openings. For example, taking the pressing device with two layers of openings as an example, the footprint of a double-layer pressing device is only half of the footprint of a single-layer pressing device. Therefore, the busbar hot pressing reflow line 000 provided in the embodiment of the present application can effectively reduce the footprint of the equipment, so that more molds can be pressed simultaneously on the same footprint.

[0045] The busbar hot pressing reflow line provided in the embodiment of the present application includes a conveyor track, a feed conveyor platform, a discharge conveyor platform and a pressing device. Along the preset conveying direction of the conveyor track, the feed conveyor platform is arranged downstream of the conveyor track, the discharge conveyor platform is arranged upstream of the conveyor track, and the pressing device is arranged between the feed conveyor platform and the discharge conveyor platform. After the busbar assembly is completed at the workstation on the conveyor track, the mold is transferred to the pressing device via the feed conveyor platform for pressing. After the mold pressing is completed, it is transferred to the discharge conveyor platform. Among them, the pressing device includes at least two stacked layers of openings, each layer of openings can be placed with a pair of molds. Therefore, in a single pressing process, at least two pairs of molds can be pressed simultaneously, so that within the limited time of a single pressing, more molds can be pressed, which is beneficial to improving the production efficiency of the product. In addition, when pressing the same number of molds, the pressing device with stacked openings can reduce the number of pressing devices compared to the pressing device with single-layer openings, thereby effectively reducing the equipment's footprint.

[0046] Optionally, based on the above embodiment, continue to refer to Figure 2 The pressing device 300 includes at least one hot pressing unit 310 and one cold pressing unit 320; the hot pressing unit 310 and the cold pressing unit 320 have the same number of openings.

[0047] Illustratively, the hot press unit 310 includes a hot press 311, a hydraulic station 312, and a vacuum pump 313, while the cold press unit 320 includes a cold press 321, a hydraulic station 312, and a vacuum pump 313. The hydraulic station 312 is mechanically connected to the hot press 311 and the cold press 321, while the vacuum pump 313 is mechanically connected to the hydraulic station 312. The at least one hot press unit 310 included in the laminating apparatus 300 is sequentially arranged near the feed conveyor 210, while the cold press unit 320 included in the laminating apparatus 300 is arranged near the discharge conveyor 220. In this way, along the preset conveying direction of the conveyor track 100, the mold that has completed busbar assembly is transferred to the hot press unit 310 via the feed conveyor 210 for hot pressing. The mold that has completed hot pressing is then transferred from the hot press unit 310 to the cold press unit 320 for cold pressing. The mold that has completed cold pressing is then transferred from the cold press unit 320 to the discharge conveyor 220, thus completing a production cycle. During the operation of the hot press unit 310 or the cold press unit 320, the vacuum pump 313 applies pressure to the hot press 311 and the cold press 321 through the hydraulic station 312, so that the hot press 311 and the cold press 321 perform a pressing operation on the mold. The stacked openings included in the hot press unit 310 and the cold press unit 320 are set to the same number, so that a certain number of molds that have completed hot pressing in one operation of the hot press 311 can enter the cold press 321 and complete cold pressing in one operation at the same time, thereby effectively shortening the production time of a certain number of molds and helping to improve product production efficiency.

[0048] Optionally, Figure 3 This is a schematic diagram of a top view layout of another busbar hot pressing return line provided in the embodiment of the present application. Figure 3 As shown, the busbar hot pressing reflow line 000 further includes: a storage rack 410 and a discharge rack 420 .

[0049] The storage rack 410 is arranged between the feeding conveying platform 210 and the pressing device 300, and the unloading rack 420 is arranged between the pressing device 300 and the discharging conveying platform 220; the storage rack 410 is provided with a photoelectric sensor, which is used to send a signal to the controller when the number of molds on the storage rack 410 reaches a preset number.

[0050] For example, the storage rack 410 and the unloading rack 420 are both racks for temporarily storing molds, and have multiple layers of space for placing molds. After a pair of molds is assembled on the busbar via the conveyor track 100, they are transported to the storage rack 410 via the feed conveyor platform 210, and the molds entering the storage rack 410 are stored in order from the bottom layer to the top layer of the storage rack 410. A photoelectric sensor is provided on the storage rack 410, which can monitor the number of molds placed on the storage rack 410. When the photoelectric sensor detects that the number of molds stored on the storage rack 410 has reached a certain height, indicating that the number of molds has reached the number that the laminating device 300 can complete laminating at one time, the photoelectric sensor sends a signal to the controller, so that after receiving the signal, the controller can control the corresponding mechanical equipment to transfer the molds stored on the storage rack 410 to the openings on each layer of the laminating device 300 to complete the simultaneous laminating of each mold. After the pressing is completed, each mold is transferred to the unloading rack 420 for temporary storage. After all the molds in the pressing device 300 are placed on the unloading rack 420, they are transferred to the unloading conveyor platform 220.

[0051] Optionally, based on the above embodiments, continue to refer to Figure 3 The busbar hot pressing reflow line 000 also includes: mobile loading and unloading equipment 510.

[0052] The mobile loading and unloading equipment 510 is used to receive the signal sent by the controller when the number of molds on the storage rack 410 reaches a preset number, transfer the molds on the storage rack 410 to the pressing equipment 300 for pressing, and transfer the molds to the unloading rack 420 after the pressing is completed.

[0053] Exemplarily, the mobile loading and unloading equipment 510 includes: a manipulator or a mobile loading and unloading vehicle. In the embodiments of the present application, a mobile loading and unloading vehicle is used as an example for explanation. When the photoelectric sensor provided on the storage rack 410 detects that the number of temporarily stored molds reaches a preset number, the photoelectric sensor may send a signal to the controller, and the controller thereby sends a signal to the mobile loading and unloading vehicle to control the mobile loading and unloading vehicle to start operation. The mobile loading and unloading vehicle determines an idle hot press 311 and transfers the molds on the storage rack 410 to the openings of each layer of the hot press 311 in turn, so that the hot press 311 heats and presses each mold at the same time. After the hot pressing is completed, the mobile loading and unloading vehicle transfers each mold from the hot press 311 to the cold press 321 according to the control signal sent by the controller, so that the cold press 321 cools and presses each mold at the same time. After the cold pressing is complete, the controller controls the mobile loading and unloading vehicle to transfer each mold from the cold press 321 to the unloading rack 420. Once all molds are placed on the unloading rack 420, they are transferred back to the conveyor track 100 via the unloading conveyor platform 220 to enter the next production cycle. By using the mobile loading and unloading equipment 510 to transfer molds during the production process, replacing manual operations, the degree of automation in the production process can be effectively improved.

[0054] Optionally, Figure 4 This is a schematic diagram of a top view layout of another busbar hot pressing return line provided in the embodiment of the present application. Figure 4 As shown, the busbar hot pressing reflow line 000 further includes: a mold loading and unloading vehicle 520 .

[0055] When the mold enters the busbar hot pressing and reflowing line 000 , the mold loading and unloading vehicle 520 is aligned with the unloading rack 420 ; when the mold leaves the busbar hot pressing and reflowing line 000 , the mold loading and unloading vehicle 520 is aligned with the storage rack 410 .

[0056] For example, in the embodiment of the present application, the mold loading and unloading vehicle 520 used can be an AGV mold loading and unloading vehicle, which is not limited here. When the mold to be produced enters the busbar hot pressing and reflowing line 000, the mold loading and unloading vehicle 520 clamps the mold and moves to align with the unloading rack 420 to transfer the mold to the unloading rack 420. From the unloading rack 420, it enters the conveyor track 100 via the discharge conveyor platform 220 for production. When the completed mold needs to leave the busbar hot pressing and reflowing line 000, the mold loading and unloading vehicle 520 moves to align with the storage rack 410, clamps the mold, and transfers it to the corresponding storage rack.

[0057] Optionally, based on the above embodiments, continue to refer to Figure 4 The conveying track 100 includes a double-layer track arranged in a vertical direction, and a demoulding station 110, a mold closing station 120 and at least one busbar assembly station 130 are provided on the conveying track 100.

[0058] Along the preset conveying direction, the demolding station 110 is arranged at the upstream position of the conveying track 100, the mold closing station 120 is arranged at the downstream position of the conveying track 100, and at least one busbar assembly station 130 is arranged between the demolding station 110 and the mold closing station 120; double-layer conveying roller tables are arranged on the double-layer track corresponding to the positions of the demolding station 110, the mold closing station 120 and the busbar assembly station 130.

[0059] For example, the demoulding station 110 on the conveying track 100 is used to separate the upper mold and the lower mold included in the mold. The busbar assembly station 130 arranged between the demoulding station 110 and the mold closing station 120 is used to assemble the busbar in the lower mold. For example, the number of busbar assembly stations 130 can be set by the user according to actual needs and is not limited here; for example: Figure 4The diagram shows a conveyor track 100 equipped with three busbar assembly stations 130. The mold closing station 120 is used to close the lower mold and upper mold after busbar assembly. The conveyor track 100 comprises two parallel tracks, each equipped with a double-layer conveyor roller platform at the corresponding station position, allowing the upper and lower molds to be transported separately after demolding.

[0060] Optionally, based on the above embodiments, continue to refer to Figure 4 The busbar hot pressing reflow line 000 also includes: a first lifting platform 610, a second lifting platform 620, a first suction lifter 630 and a second suction lifter 640.

[0061] Along the preset conveying direction, the first suction lifter 630 is arranged at the head end of the conveying track 100, and the first lifting platform 610 is arranged between the first suction lifter 630 and the demolding station 110; along the preset conveying direction, the second suction lifter 640 is arranged at the tail end of the conveying track 100, and the second lifting platform 620 is arranged between the second suction lifter 640 and the mold closing station 120.

[0062] For example, when the mold enters the conveyor track 100 to begin production, it is first separated into an upper mold and a lower mold at the mold removal station 110. Since busbar assembly is not required on the upper mold, the first suction lifter 630 transfers the upper mold to the first lifting platform 610. As the first lifting platform 610 descends, the upper mold is directly transferred from the conveyor roller table located on the lower level to the conveyor track 100 to the second lifting platform 620. The lower mold is sequentially transferred to each busbar assembly station 130 via the conveyor roller table located on the upper level for busbar assembly. After the busbar assembly is completed, the lower mold is transferred to the mold closing station 120. The second lifting platform 620 rises to lift the upper mold, which is then lifted by the second suction lifter 640 and moved to the mold closing station 120, thereby closing the upper and lower molds.

[0063] An embodiment of the present application also provides a busbar hot pressing system. Figure 5 This is a schematic diagram of the top view layout of a busbar hot pressing system provided in an embodiment of the present application. Figure 5 As shown, the busbar hot pressing system includes: a mold storage rack 001, an electric control room 002 and two busbar hot pressing reflow lines 000 provided in any of the above embodiments.

[0064] The two busbar hot pressing reflow lines 000 are arranged in an axially symmetrical manner, and the electric control room 002 is set on the straight line where the symmetry axis of the two busbar hot pressing reflow lines 000 is located; the electric control room 002 includes a controller, which connects the busbar hot pressing reflow line 000 with the mobile loading and unloading equipment and the mold loading and unloading vehicle to achieve communication, and controls the pressing equipment to complete the mold pressing.

[0065] Specifically, the preset conveying directions of the two busbar hot pressing and reflowing lines 000 are opposite and arranged in an axisymmetric manner. During the production process, the two busbar hot pressing and reflowing lines 000 operate simultaneously. The electric control room 002 set on the straight line where the symmetry axis is located can be connected to the mobile loading and unloading equipment and the mold loading and unloading vehicle. At the beginning of production, the mold loading and unloading vehicle is controlled to clamp the corresponding mold from the mold storage rack 001 and transfer it to the busbar hot pressing and reflowing line 000 for busbar assembly. When the busbar assembly is completed, the mobile loading and unloading equipment is controlled to transfer the mold to the pressing equipment in the busbar hot pressing and reflowing line 000. By identifying the mold code, the controller can automatically call the matching pressing parameters from the pre-stored parameter library to press the mold. Among them, the pre-stored parameter library includes data such as the hot pressing time and hot pressing temperature executed by the hot press, as well as data such as the cold pressing time and cold pressing temperature executed by the cold press, which are not limited here. After the mold is completed, the controller controls the mold loading and unloading vehicle to clamp the mold and transfer it to the corresponding position of the mold storage rack 001 for storage.

[0066] The busbar hot pressing system is provided with the busbar hot pressing reflow line 000 provided by any of the above embodiments, and adopts a pressing device including at least two layers of openings, each layer of openings can be placed with a pair of molds, so that in one pressing process, at least two pairs of molds can be pressed simultaneously, thereby facilitating the improvement of product production efficiency. For example, Figure 5 The figure shows a busbar hot pressing system comprising six hot presses with four openings and two cold presses with four openings, which occupies an area of ​​about 400 square meters. When pressing the same number of molds, the use of laminating equipment with stacked openings can reduce the number of pressing equipment required and the floor space can be reduced by 140 square meters compared to the use of laminating equipment with single-layer openings, thereby effectively reducing the floor space of the equipment.

[0067] The above specific embodiments do not constitute a limitation on the scope of protection of this application. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application shall be included within the scope of protection of this application.
