They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example like Figure 1 As shown, a four-position clamping mechanism described in the present invention comprises an upper mounting plate 1 and a lower mounting plate 2 , wherein the bottom end of the upper mounting plate 1 is fixedly connected to the top end of the lower mounting plate 2 via a connecting column 3 .

[0025] The upper mounting plate 1 is connected to a four-position fixed clamp mechanism 6 through a telescopic moving mechanism, and the four-position fixed clamp mechanism 6 is used to clamp multiple groups of stacked photovoltaic cells 5 to achieve grabbing and transfer. The telescopic moving mechanism includes a telescopic element 4, and the telescopic element 4 is connected to the four-position fixed clamp mechanism 6 through a connecting rod assembly 8. The telescopic element 4 is a telescopic cylinder, which is installed on the top of the upper mounting plate 1. The cylinder rod of the telescopic cylinder penetrates the upper mounting plate 1 and is connected to a moving block 81 located below the upper mounting plate 1. Four connecting blocks 82 are arranged in a circular array on the side of the moving block 81. The cylinder rod of the telescopic cylinder can drive the moving block 81 to rise or fall, thereby driving the four connecting blocks 82 to rise or fall.

[0026] like Figure 2 As shown, the connecting rod assembly 8 includes four double-ended connecting rods 83 and four connecting seats 84. The top ends of the double-ended connecting rods 83 are respectively hinged to the connecting blocks 82 in their respective directions, and the bottom ends of the double-ended connecting rods 83 are respectively hinged to the top ends of the connecting seats 84 in their respective directions. The lifting and lowering of the connecting blocks 82 can drive the double-ended connecting rods 83 to rotate, thereby driving the connecting seats 84 to move.

[0027] like Figure 3 As shown, the four-position fixed clamp mechanism 6 includes four clamps, which are arranged in a circular array on the side of the lower mounting plate 2. The clamp includes a fixed plate 1 61, a fixed plate 2 62 is vertically arranged on the top of the fixed plate 1 61, and an L-shaped clamp plate 63 is arranged on the lower inner side of the fixed plate 1 61. The fixed plate 1 61, the fixed plate 2 62, and the L-shaped clamp plate 63 are an integrated structure. The four-position fixed clamp mechanism 6 is connected to the top of the lower mounting plate 2 through a sliding structure 7. Figure 4 As shown, the sliding structure 7 includes a sliding seat 71, which is arranged at the bottom end of the fixed plate 2 62, and the sliding seat 71 is slidably connected to the lower mounting plate 2 through a sliding rail 72, and the sliding rail 72 is installed at the top of the lower mounting plate 2. A sliding groove is arranged on the sliding seat 71, and the sliding rail 72 is inserted into the sliding groove and slidably connected to the sliding groove. A protruding slider 73 is arranged in the sliding groove, and a sliding groove 74 adapted to the slider 73 is arranged on the side of the sliding rail 72, and the slider 73 is inserted into the sliding groove 74 and slidably connected to the sliding groove 74. The slider 73 cooperates with the sliding groove 74 to prevent the sliding seat 71 from falling off the sliding rail 72.

[0028] The bottom end of the connecting seat 84 is connected to the top end of the fixed plate 62, and the connecting seat 84 is fixedly installed on the fixed plate 62. Since the sliding seat 71 in the sliding structure 7 slides on the sliding rail 72, when the double-headed connecting rod 83 rotates, the fixed plate 62 is driven to slide inward or outward through the sliding structure 7 through the connecting seat 84, thereby driving the entire clamp to move, clamping and grasping or releasing multiple groups of stacked photovoltaic cells 5.

[0029] like Figure 5As shown, a buffer 9 and a photoelectric detection sensor 10 are provided at the bottom end of the lower mounting plate 2. The buffer 9 includes a pressing cylinder 91 provided at the bottom end of the lower mounting plate 2, and the cylinder rod of the pressing cylinder 91 is connected to a cylinder mounting middle plate 92. Two mounting holes are provided on the cylinder mounting middle plate 92, and a guide bearing 96 is installed in the mounting hole. The guide bearing 96 is fixedly connected to the cylinder mounting middle plate 92 through a bearing fixing collar. The guide bearing 96 is sleeved on a guide rod 97, and the top end of the guide rod 97 is connected to the upper connecting plate 93. The bottom end of the guide rod 97 is connected to the top end of a lower connecting plate 94 for pressing the photovoltaic cell sheet 5, and a soft rubber gasket 95 is provided at the bottom end of the lower connecting plate 94. A spring 98 is provided between the cylinder mounting middle plate 92 and the lower connecting plate 94, and the spring 98 is sleeved on the guide rod 97.

[0030] When the pressing cylinder 91 drives the lower overall structure to move downward, the lower connecting plate 94 presses the photovoltaic cell 5 through the soft rubber gasket 95, and the lower connecting plate 94 is subjected to an upward reaction force, driving the guide rod 97 to slide upward in the guide bearing 96, and the guide bearing 96 slides upward to drive the upper connecting plate 93 to move upward; at the same time, the spring 98 is in a compressed state, and the reaction force of the compression of the spring 98 gives the lower connecting plate 94 a downward force, which acts on the photovoltaic cell 5 through the lower connecting plate 94 and the soft pad. The buffer 9 can not only press the photovoltaic cell 5, but also not crush the photovoltaic cell 5. The lower connecting plate 94 presses the photovoltaic cell 5 through the soft rubber gasket 95, but in order not to crush the photovoltaic cell 5, after contacting the product, the spring 98 is compressed, and the upper connecting plate 93 retreats upward, pressing on the surface of the product with a certain pressure.

[0031] The photoelectric detection sensor 10 is an existing photoelectric sensor. Within its detection range, the detection signal emitted hits the surface of the photovoltaic cell 5. The signal reflected back from the surface of the photovoltaic cell 5 is received by the photoelectric detection sensor 10, which is regarded as capturing the photovoltaic cell 5. If no reflected feedback signal is received within its detection range, it is regarded as not capturing the photovoltaic cell 5.

[0032] When in use, the upper mounting plate 1 is installed on the existing device for driving the entire clamping mechanism to move, and the cylinder rod of the telescopic cylinder drives the moving block 81 to rise, and the rising of the moving block 81 drives the connecting block 82 to rise, thereby driving the upper end of the double-headed connecting rod 83 to rotate outward and move upward, and the double-headed connecting rod 83 moves through the connecting seat 84 to drive the fixed plate 2 62 to slide inward, thereby driving the fixed plate 1 61 and the L-shaped claw plate 63 to move inward, clamping multiple groups of stacked photovoltaic cells 5 to achieve grasping.

[0033] Therefore, the present invention adopts the above-mentioned four-position clamping mechanism, which can quickly and accurately transfer and transport the photovoltaic cell 5 without damaging the cell.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
