Description

Technical Field

[0001] The present invention belongs to the technical field of battery processing equipment, and particularly relates to a battery sheet pitch-changing system. Background Art

[0002] Under the pressure of energy crisis and environmental pollution problems, environmental protection and energy conservation have become the theme of the current social development. Photovoltaic cells are an important part of energy conservation and environmental protection because they can provide environmentally friendly and pollution-free clean energy. Currently, it is a very important process section to produce photovoltaic cells using vacuum coating equipment, which plays a very important role in it.

[0003] In a vacuum coating equipment, battery sheets need to be coated in the coating equipment with a carrier plate as the carrier. Usually, battery sheets are transferred through a flower basket. There are two battery sheets on each layer in the flower basket. The two battery sheets are placed on the carrier plate by the flower basket and then coated.

[0004] However, the pitch between battery sheets in the flower basket limits the pitch between battery sheets in the carrier plate, resulting in a relatively large pitch between every two battery sheets. Furthermore, it limits the production of more battery sheets by the vacuum coating equipment in a limited space. In order to produce more battery sheets in a limited space, that is, to make the distance between battery sheets smaller, it is directly to use a tooling block to push the battery sheet to slide for pitch-changing. During the pushing process, friction will occur between the battery sheet and the tooling block, resulting in wear of the battery sheet and seriously affecting the battery efficiency.

Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Please refer to Figures 1 - 5 , which shows a solar cell variable pitch system provided by an embodiment of the present invention and is applied to a transmission system. The transmission system includes at least two conveyor belts 100 arranged at intervals. The conveyor belt 100 is used to transport at least one solar cell 200. It should be noted that in this embodiment, the transmission system is not limited to the conveyor belt 100 shown in this example, and it also has a power source for driving the conveyor belt 100, and the power source can be a servo motor. The servo motor can be used to drive the conveyor belt 100 to move.

[0037] Specifically, to facilitate solving the technical problem that the existing variable pitch method for the battery cell 200 may cause wear of the battery cell 200 and affect the battery efficiency, the variable pitch system 300 includes at least two brackets 310 having a moving gap portion 320, at least two power driving devices, and at least one lifting device 350;

[0038] The conveyor belt 100 is disposed within the moving gap portion 320 such that after the battery cell 200 is conveyed by the conveyor belt 100, the battery cell 200 is directly opposite to the bracket 310;

[0039] Wherein, each bracket 310 is respectively connected to the lifting device 350 through at least one power driving device. The lifting device 350 is used to drive the bracket 310 to move, so that the battery cell 200 is lifted by the bracket 310 and separated from the conveying area of the conveyor belt 100, and at least two power driving devices are respectively used to drive at least two brackets 310 to move relative to each other, so as to vary the distance between at least two battery cells 200.

[0040] For the convenience of understanding this case, two conveyor belts 100, two brackets 310, and two power driving devices are used for illustration. It should be noted that the number two does not limit the number of conveyor belts 100, brackets 310, and power driving devices, and other numbers may also be included, which will not be specifically described herein.

[0041] Specifically, when adjusting the distance between two adjacent battery cells 200, the two conveyor belts 100 can be used to synchronously convey the two battery cells 200 respectively. When the conveyor belt 100 conveys the battery cell 200 to a certain distance, the two battery cells 200 will be directly opposite to the two brackets 310 respectively. Through the drive of the lifting device 350, the power driving device and the bracket 310 perform a lifting movement. When in the rising state, the bracket 310 will lift the battery cell 200, so that the battery cell 200 is separated from the conveying range of the conveyor belt 100. Finally, the distances between the two brackets 310 are adjusted respectively by the two power driving devices to achieve the purpose of varying the pitch of the battery cell 200. Through this setting, it is possible to avoid the situation that the battery cell 200 is worn during the variable pitch process and affects the battery efficiency.

[0042] It should be noted that in some embodiments, the bracket 310 may be arranged in a U-shaped structure. The opening of the U-shaped structure can be used to lift both ends of the battery cell 200, and the size of the moving gap portion 320 provided in the bracket 310 is larger than the cross-sectional size of the conveyor belt 100. By using the size difference, it is possible to avoid collision between the bracket 310 and the conveyor belt 100 during the movement of the bracket 310.

[0043] To facilitate the improvement of the practicality of the pitch-changing system 300 of the present invention, in some other preferred embodiments, the transmission system includes a plurality of transmission belts 100 arranged at intervals. Among them, the pitch-changing system 300 includes a plurality of brackets 310 having moving gap portions 320 and a plurality of power driving devices. Each transmission belt 100 is respectively disposed within the moving gap portion 320 of each bracket 310. Through the arrangement of the plurality of transmission belts 100, the plurality of brackets 310, and the plurality of power driving devices, the pitch of a plurality of battery wafers 200 can be changed in one process to improve the practicality during battery production.

[0044] Further, in some preferred embodiments, the bracket 310 can also be of a split type. For example, the bracket 310 includes a first support rod 311 and a second support rod 312. The first support rod 311 and the second support rod 312 are arranged oppositely, and there is a gap between the first support rod 311 and the second support rod 312 to form a moving gap portion 320. To facilitate driving the battery wafer 200 to change its pitch, the pitch-changing system 300 includes a plurality of first power driving devices 330 and a plurality of second power driving devices 340. Each first power driving device 330 is respectively connected to each first support rod 311 to drive the first support rod 311 to move, and each second power driving device 340 is respectively connected to each second support rod 312 to drive the second support rod 312 to move.

[0045] The first power driving device 330 and the second power driving device 340 can respectively drive and control the first support rod 311 and the second support rod 312, so that the functions of lifting and pitch-changing can be realized for battery wafers 200 of different sizes, further improving the practicality of the pitch-changing system 300 in this embodiment.

[0046] For easy understanding, please specifically refer to Figure 5 As shown, the first support rod 311, the second support rod 312, the first power driving device 330, and the second power driving device 340 can be in two groups, such as Figure 5 the left and right two groups shown. The corresponding first support rod 311 and second support rod 312 in the two groups can lift the left and right two battery wafers 200, and the distance between the left and right two battery wafers 200 can be changed by the corresponding first power driving device 330 and second power driving device 340 in the two groups. It should be noted that Figure 5 the two groups shown are only examples, and there can be multiple groups distributed, which are not specifically limited here.

[0047] Further, the conveyor belt 100 is used to convey a plurality of battery cells 200. Each first support rod 311 includes a plurality of first lifting members 3111 arranged at intervals, and each second support rod 312 includes a plurality of second lifting members 3121 arranged at intervals, so as to lift opposite ends of each battery cell 200 on the conveyor belt 100 through the plurality of first lifting members 3111 and the plurality of second lifting members 3121. That is to say, each conveyor belt 100 can convey a plurality of battery cells 200. To facilitate the lifting and pitch variation of the plurality of battery cells 200 on each conveyor belt 100, by arranging the plurality of first lifting members 3111 and the plurality of second lifting members 3121, the plurality of battery cells 200 on one conveyor belt 100 can be lifted.

[0048] In addition, in some embodiments, the first support rod 311 further includes two first transverse support sub-rods 3112 and a plurality of first longitudinal support sub-rods 3113. The plurality of first longitudinal sub-rods are arranged at intervals between the two first transverse support sub-rods 3112, and one of the first transverse support sub-rods 3112 is connected to the first power driving device 330, and a plurality of first lifting members 3111 are arranged at intervals on the other first transverse support sub-rods 3112. The second support rod 312 further includes two second transverse support sub-rods 3122 and a plurality of second longitudinal support sub-rods 3123. The plurality of second longitudinal sub-rods are arranged at intervals between the two second transverse support sub-rods 3122, and one of the second transverse support sub-rods 3122 is connected to the second power driving device 340, and a plurality of second lifting members 3121 are arranged at intervals on the other second transverse support sub-rods 3122. By arranging the plurality of first longitudinal support sub-rods 3113 and the plurality of second longitudinal support sub-rods 3123, the stability of the first support rod 311 and the second support rod 312 can be provided.

[0049] Moreover, to ensure the lifting of battery cells 200 of different sizes, each first lifting member 3111 is detachably connected to a first transverse support sub-rod 3112, and each second lifting member 3121 is detachably connected to a second transverse support sub-rod 3122. The detachable connection can be carried out by means of bolts or clamping, and no special limitation is made here.

[0050] In addition, the lifting device 350 includes a lifting driving member 351 and a supporting bottom plate 352. The output end of the lifting driving member 351 is connected to the supporting bottom plate 352. Among them, each first power driving device 330 and each second power driving device 340 are both arranged on the supporting bottom plate 352.

[0051] It should be noted that the above-mentioned first power driving device 330, second power driving device 340, and lifting driving member 351 can all adopt cylinders. And to improve the intelligence of this system, an LPC controller can also be arranged to intelligently control the first power driving device 330, second power driving device 340, and lifting driving member 351 respectively, so as to realize the characteristic of intelligently changing the distance of the battery cell 200.

[0052] After the distance of the battery cell 200 is changed, it will be directly placed on the carrier plate to perform the battery cell coating process. Since the coating process is a conventional existing technology in this field, no special description will be made here.

[0053] In summary, a battery cell distance-changing system provided by an embodiment of the present invention has at least the following beneficial effects compared with the existing methods for changing the distance of battery cells:

[0054] In the battery cell distance-changing system provided by the present invention, by applying the distance-changing system 300 to the transmission system for transmitting the battery cells 200, the two transmission belts 100 in the transmission system can synchronously transmit two battery cells 200 respectively. When the transmission belt 100 transmits the battery cell 200 to a certain distance, the two battery cells 200 will respectively face two brackets 310. Through the drive of the lifting device 350, the power driving device and the bracket 310 perform lifting movements. When in the rising state, the bracket 310 will lift the battery cell 200, so that the battery cell 200 is out of the transmission range of the transmission belt 100. Finally, the distances between the two brackets 310 are adjusted respectively by using the two power driving devices to achieve the purpose of changing the distance of the battery cell 200. Through this setting, it is possible to avoid the situation that the battery cell 200 is worn during the distance-changing process and affects the battery efficiency.
