[0039] When the existing solar cell clamping device clamps the cell group, the cell group is only clamped on two sides, while the other two sides are not clamped. This causes the cell group to slip relative to each other during transfer, resulting in uneven arrangement of the cells.

[0040] Based on this, refer to Figure 1 and Figure 2 The solar cell clamping device provided by the present invention includes:

[0041] Mounting seat 1;

[0042] Four clamping jaws 2 are slidably connected to the mounting base 1, and the four clamping jaws 2 are distributed at 90° intervals around the same center line;

[0043] The driving mechanism 3 is mounted on the mounting base 1 and is used to drive the four clamping jaws 2 to close or open.

[0044] The solar cell clamping device provided herein clamps a cell group, and the four clamping jaws 2 are driven by a drive mechanism 3 to close toward the center line, thereby centering and aligning multiple cells and improving the neatness of the cell group. During the transfer of a cell group, the four clamping jaws 2 abut against the four sides of the cell, thereby preventing relative slippage of the cells and further improving the neatness of the cell group.

[0045] Continue to refer to Figure 1 The mounting base 1 includes an upper connecting plate 11, a lower connecting plate 12, and several columns 13 connected between the upper connecting plate 11 and the lower connecting plate 12. The driving mechanism 3 is mounted on the upper connecting plate 11, and the four clamping jaws 2 are all slidably connected to the lower connecting plate 12. The mounting base 1 also includes a connector 14 connected to the upper connecting plate 11. The connector 14 is used to connect to a transfer device; the transfer device can be a three-axis slide device or a robot, which is used to drive the mounting base 1 to move within a space, thereby achieving the transfer of the battery cell group.

[0046] Reference Figure 3 and Figure 4 The dotted line position in the figure represents the battery cell group. Each clamp 2 includes a first horizontal plate, a second horizontal plate and a vertical plate connected between the first horizontal plate and the second horizontal plate. The first horizontal plate is slidably connected to the mounting base 1, and the second horizontal plate, the vertical plate and the mounting base 1 form a clamping area for placing the battery cells.

[0047] Specifically, the first and second horizontal plates are located above and below the lower connecting plate 12, with a gap between them. The vertical plates are located around the lower connecting plate 12, with their upper and lower ends connected to the first and second horizontal plates, respectively. This arrangement creates a clamping area for placing the battery cells between the second horizontal plate, the vertical plates, and the lower connecting plate 12.

[0048] In the above structure, the four vertical plates are used to push against the four sides of the battery pack, and the four second horizontal plates are used to support the lower end surface of the battery pack. To protect the battery cell surface from damage, elastic pads 4 are attached to the side of the second horizontal plates near the clamping area and / or the side of the vertical plates near the clamping area.

[0049] It should be noted that the cross-sectional profile of a cell is typically square or rectangular. The four vertical plates are arranged in pairs. When the cross-sectional profile of the cell is square, the spacing between the two pairs of vertical plates is equal; when the cross-sectional profile of the cell is rectangular, the spacing between the two pairs of vertical plates is unequal. The spacing between the two pairs of vertical plates is adaptively adjusted based on the size of the cell. The spacing between the two opposing vertical plates can be adjusted by changing the length of the first horizontal plate.

[0050] Continue to refer to Figure 3 and Figure 4 The drive mechanism 3 includes a drive source 31, a slide 32, and four connecting rods 33. The drive source 31 is used to drive the slide 32 to move along the extension direction of the centerline of the four clamping jaws 2. One end of each of the four connecting rods 33 is hinged to the slide 32, and the other ends of the four connecting rods 33 are hinged to the four clamping jaws 2 in a one-to-one correspondence. In this embodiment, the centerlines of the four clamping jaws 2 are parallel to the vertical direction.

[0051] As an optional embodiment, the drive source 31 is a pneumatic cylinder. The cylinder body of the drive source 31 is connected to the mounting base 1, and the piston rod of the drive source 31 is connected to the slide 32. The slide 32 includes an annular sleeve and four hinged ears fixed to the outer circumference of the annular sleeve. The annular sleeve is mounted on the piston rod of the drive source 31. One end of four connecting rods 33 is hinged to the four hinged ears via pins, and the other ends of the four connecting rods 33 are hinged to the four clamping jaws 2 via pins. When the piston rod of the drive source 31 retracts or extends, the slide 32 is driven by the piston rod to rise or fall, and the slide 32 drives the four clamping jaws 2 to close or open via the connecting rods 33.

[0052] Continue to refer to Figure 3 and Figure 4 The driving mechanism 3 also includes a spring 34 and a locking member 35, wherein: the slide 32, the spring 34 and the locking member 35 are sequentially mounted on the piston rod of the driving source 31 from top to bottom; the two ends of the spring 34 are respectively in contact with the slide 32 and the locking member 35.

[0053] Specifically, a step surface is provided on the piston rod of the driving source 31, and the slide 32 and the spring 34 are slidably mounted on the piston rod of the driving source 31 and are located between the step surface and the locking member 35; the locking member 35 is a nut or a cap screwed to the end of the piston rod of the driving source 31, and the two ends of the spring 34 are respectively in contact with the slide 32 and the locking member 35. Figure 3 When the four clamping jaws 2 are in the open state, the slide 32 is clamped between the step surface and the spring 34 under the elastic force of the spring 34. Figure 4 When the four clamping jaws 2 are in the closed state, the slide 32 can float up and down, thereby stably clamping the battery cell group while avoiding excessive clamping force on the battery cell group, thereby avoiding damage to the surface of the battery cell group.

[0054] In the above structure, by adjusting the position of the locking member 35 on the piston rod of the driving source 31 , the elastic force applied by the spring 34 to the slide 32 can be adjusted, thereby adjusting the clamping force applied by the clamping jaws 2 to the battery cell group.

[0055] Continue to refer to Figure 4The solar cell clamping device further includes four slide rails 5 and four sliders 6. The four slide rails 5 are fixedly connected to the mounting base 1. The four sliders 6 are slidably connected to the four slide rails 5 in a one-to-one manner, and the four sliders 6 are fixedly connected to the four clamping jaws 2 in a one-to-one manner. The slide rails 5 and sliders 6 are used to guide the clamping jaws 2 so that the clamping jaws 2 move smoothly along a set trajectory.

[0056] Continue to refer to Figure 4 The solar cell clamping device further comprises a photoelectric switch 7, which is mounted on the mounting base 1 with its light-emitting end facing the clamping area. The photoelectric switch 7 can detect whether the clamping jaw 2 is holding a cell group.

[0057] In this embodiment, the cylinder of the drive source 31 is fixed to the upper end surface of the upper connecting plate 11. The piston rod of the drive source 31 extends downward through the upper connecting plate 11 and is connected to the clamping jaw 2 via a slide 32 and a connecting rod 33. The slide rail 5 is fixed to the upper end surface of the lower connecting plate 12. The first horizontal plate of the clamping jaw 2 is slidably connected to the slide rail 5 via a slider 6. The photoelectric switch 7 is fixed to the lower connecting plate 12. This arrangement achieves a fixed installation of the entire device.

[0058] Reference Figure 5 and Figure 6 The dotted area in the drawing represents the battery cell. There are four photoelectric switches 7 , which are respectively close to the four edges of the battery cell in the clamping area.

[0059] When the clamp 2 moves to the top of the battery pack, the four photoelectric switches 7 are used to determine whether the battery pack is in the set position. Figure 5 When the light emitted by the four photoelectric switches 7 is blocked, it means that the battery cell is in the set position. At this time, the four clamps 2 are controlled to descend and clamp the battery cell group. Figure 6 When the light emitted by at least one photoelectric switch 7 is not blocked, it means that the battery cell deviates from the set position. At this time, the four clamps 2 are controlled to move in the horizontal direction until the light emitted by the four photoelectric switches 7 is blocked. Then, the four clamps 2 are controlled to descend and clamp the battery cell group.

[0060] As described above, this embodiment provides four photoelectric switches 7, which can not only detect whether the clamping jaws 2 are holding a battery cell group, but also determine whether the battery cell group is located at a set position before clamping the battery cell group. This can avoid the problem of the clamping jaws 2 failing to clamp the battery cell during the process of clamping the battery cell, reduce the error rate of the device during operation, and avoid the problem of the clamping jaws 2 colliding with the battery cell and causing damage to the battery cell.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
