Description

Technical Field

[0001] This utility model relates to the field of solar cell technology, and in particular to an automatic cell array mounting device. Background Technology

[0002] With the development of photovoltaic technology, triple-junction gallium arsenide (GaAs) solar cells are widely used in aerospace and high-end energy fields due to their high conversion efficiency. However, the cell array mounting process still faces the following challenges: Since the bonding accuracy between the cells and the honeycomb panel needs to be better than ±0.1mm, and surface scratches or contamination must be avoided, traditional manual operation struggles to guarantee consistency. Furthermore, existing equipment largely relies on segmented processing, with separate processes for series detection, positioning, and mounting, resulting in low efficiency and a lack of integrated visual inspection and pre-pressing functions. Therefore, there is an urgent need for an automated system integrating high-precision detection, adaptive adhesive application, and multi-axis linkage bonding to improve the mounting efficiency and yield of triple-junction GaAs cells.

[0023] The present invention will now be described in detail with reference to various embodiments. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0024] like Figure 1-3 As shown, this embodiment provides an automatic battery array patching device, which includes: a pick-and-place mechanism 10, a dispensing mechanism 20, a platform mechanism 30, and a motion mechanism 40.

[0025] The platform mechanism 30 is used to support the battery cells that need to be patched. In one embodiment, the platform mechanism 30 is integrally cast from a high-precision cast iron platform and manufactured using a grinding process, which can provide a flatness of better than 0.05mm for patching operations.

[0026] The motion mechanism 40 is used to drive the pick-up and place mechanism 10 and the dispensing mechanism 20 to perform material picking and dispensing actions above the platform mechanism 30. The material picking and dispensing actions mentioned here include three-dimensional motion in the XYZ axis directions, as well as its own rotational motion.

[0027] Specifically, the motion mechanism 40 is mounted on the platform mechanism 30 and includes an X-axis assembly 41, a Y-axis assembly 42, a Z-axis assembly 43, and an R-axis assembly 44. Thus, the X-axis assembly 41, the Y-axis assembly 42, and the Z-axis assembly 43 enable the pick-and-place mechanism 10 and the dispensing mechanism 20 to perform three-dimensional motion in the XYZ directions, as well as the rotational motion of the pick-and-place mechanism 10 itself.

[0028] In this configuration, the Z-axis assembly 43 is driven by the X-axis assembly 41 and the Y-axis assembly 42 to perform XY motion above the platform mechanism 30, and the R-axis assembly 44 is driven by the Z-axis assembly 43 to perform lifting motion above the platform mechanism 30. In one embodiment, the Y-axis assembly 42 consists of two sets of parallel Y-axis linear motors, and the X-axis assembly 41 consists of one set of X-axis linear motors. The base 410 on which the X-axis linear motors are located is connected to the two Y-axis linear motors.

[0029] To independently drive the pick-and-place mechanism 10 and the dispensing mechanism 20 to perform lifting and lowering movements, the Z-axis assembly 43 includes a first Z-axis unit 431 and a second Z-axis unit 432. The first Z-axis unit 431 and the second Z-axis unit 432 are distributed on both sides of the X-axis assembly. The first Z-axis unit 431 independently drives the pick-and-place mechanism 10 to perform lifting and lowering movements; the second Z-axis unit 432 independently drives the dispensing mechanism 20 to perform lifting and lowering movements. Thus, a single motion mechanism 40 can drive the pick-and-place mechanism 10 and the dispensing mechanism 20 to perform lifting and lowering movements, simplifying the equipment structure. In one embodiment, both the first Z-axis unit 431 and the second Z-axis unit 432 are Z-axis linear motors.

[0030] Furthermore, the motion mechanism 40 also includes a Y-axis dispensing arm 45; the dispensing mechanism 20 is connected to the second Z-axis unit 432 via the Y-axis dispensing arm 45. In this case, the dispensing mechanism 20 can make fine adjustments to its position in the Y-axis direction under the drive of the Y-axis dispensing arm 45, thus adapting to actual dispensing requirements.

[0031] The R-axis assembly 44 is used to drive the pick-and-place mechanism 10 to rotate. It includes a rotary motor, the output end of which is connected to the pick-and-place mechanism 10. The rotary motor is also driven by the Z-axis assembly 43 to move up and down above the platform mechanism 30.

[0032] The pick-and-place mechanism 10 is used to pick up the battery cells to be bonded. Specifically, the pick-and-place mechanism 10 includes a suction cup assembly. The suction cup assembly is drively connected to the R-axis assembly 44 and is driven by the motion mechanism 40 to perform bonding motion above the platform mechanism 30. The suction cup assembly includes several suction nozzles 11; each of the suction nozzles 11 is connected to the base of the suction cup assembly via a telescopic cylinder 12. Thus, any one of the suction nozzles 11 can be driven by the telescopic cylinder 12 to descend to the working position to pick up the material.

[0033] In one embodiment, the plurality of suction nozzles 11 are arranged in an array on the base. For example, the plurality of suction nozzles 11 are divided into 30-series spacing suction cup groups and 40-series spacing suction cup groups according to the product spacing. Each suction cup group consists of 28 independent suction cups, which can independently pick up materials according to the required number of materials by the system. The shortest material picking distance is 1 battery and the longest is 28 batteries.

[0034] Furthermore, to achieve precise material handling by the pick-and-place mechanism 10, the mechanism also includes a vision component 13, which is mounted on the R-axis assembly 44 and includes a downward-facing industrial camera. Thus, by using the vision component 13 in conjunction with the multi-axis module, high-precision placement and bonding of the battery cells are achieved, ensuring minimal alignment error between the battery and the honeycomb panel and improving photoelectric conversion efficiency.

[0035] The dispensing mechanism 20 is used to provide the adhesive required during patch placement. The dispensing mechanism 20 includes a dispensing mechanism 20. Specifically, the dispensing mechanism 20 is connected to the X-axis assembly 41 or the Y-axis assembly 42 and is driven by the motion mechanism 40 to perform dispensing motion above the platform mechanism 30.

[0036] In one embodiment, the dispensing mechanism 20 includes a dispensing head 21 and a mixing screw pump 22 and a dispensing screw pump 23 respectively connected to the dispensing head 21. Thus, the dual-liquid screw pumps provide quantitative control of the adhesive application to the product, ensuring both effective application and the required application area.

[0037] In summary, this invention utilizes a vision component combined with a multi-axis module to achieve high-precision placement and bonding of battery cells, ensuring minimal alignment error between the battery and the honeycomb panel and improving photoelectric conversion efficiency. Simultaneously, the twin-screw dispensing mechanism avoids bonding failures caused by excess or insufficient adhesive. Furthermore, the suction cup assembly can grip multiple batteries at once, improving production efficiency.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
