Description

Technical Field

[0001] The utility model relates to the technical field of transportation, in particular to a photovoltaic assembly battery string correction device. Background Art

[0002] Photovoltaic modules (also called solar panels) are the core and most important part of solar power generation systems, including backplanes, frames, junction boxes, photovoltaic cells, welding strips, terminal welding rods, etc. The welding strips will connect photovoltaic cells into battery strings and then conduct current through terminals. Welding strips, photovoltaic cells, and terminal welding rods all rely on welding to form electrical connections.

[0003] The photovoltaic module battery string is first transported to the position through the conveyor line, and then the angle is adjusted by the correction device so that the welding point is located on a straight line perpendicular to the conveying direction of the conveyor line, so that the welding mechanism can start welding. Because the main material of photovoltaic modules is glass, the clamping force must not be too large during correction, otherwise the edge of the photovoltaic module will be damaged and cause quality problems.

[0004] Our company has applied for a Chinese patent CN210200673U, which discloses a battery string alignment device, which can effectively align the batteries with each other through the cooperation of the adjustment component and the drive component. One side of the alignment is a stationary baffle, and the other side uses a spring. When the alignment clamp is in place, the spring is driven by the electric cylinder to move closer to the block, thereby clamping the battery string with the block. However, the force of the electric cylinder is still relatively large, and even with the spring buffer, the clamping force is still not small enough.

[0005] Therefore, it is necessary to improve the correction device structure to solve the above problems. Summary of the invention

[0006] The main purpose of the utility model is to provide a photovoltaic module battery string correction device, which can achieve the clamping of the battery string by the first sliding plate and the second sliding plate with a relatively light force, thereby preventing the side of the battery string from being clamped and cracked.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a photovoltaic module battery string correction device, comprising a first sliding plate, a second sliding plate, an adjustment mechanism for controlling the spacing between the first sliding plate and the second sliding plate along the X direction, and a guiding mechanism for limiting the movement of the first sliding plate and the second sliding plate along the X direction, the adjustment mechanism comprising a linear drive and a connecting rod assembly, the linear drive drives the first sliding plate or the second sliding plate to move along the X direction, the connecting rod assembly comprises a fixed rotating shaft, a pendulum block, and a first connecting rod and a second connecting rod with equal arm lengths, the axis of the fixed rotating shaft is along the Z direction and fixed to the center position of the pendulum block, one end of the pendulum block is hinged to the middle of the first sliding plate through the first connecting rod, and the other end of the pendulum block is hinged to the middle of the second sliding plate through the second connecting rod.

[0008] Specifically, a plurality of alignment wheels are arranged along the Y direction on the first sliding plate, and a plurality of paddles are arranged along the Y direction on the second sliding plate. The axes of all the alignment wheels are along the Z direction, and the surfaces of all the paddles are in the same YZ plane.

[0009] Specifically, the guiding mechanism is two X-direction slide rails, and two sliders are respectively provided at the lower parts of the first slide plate and the second slide plate, and the two sliders slide along the X-direction slide rails respectively.

[0010] Specifically, the linear drive member passes below the center position between the first sliding plate and the second sliding plate.

[0011] The beneficial effects of the technical solution of the utility model are:

[0012] The utility model can drive a sliding plate to move through a linear drive member, and then drive another sliding plate to move in the opposite direction through a connecting rod assembly, so that the driving force is distributed into two opposite clamping forces, thereby achieving the clamping of the battery string by the first sliding plate and the second sliding plate with a lighter force, thereby preventing the side of the battery string from being clamped and cracked.

[0019] The utility model is further described in detail below in conjunction with specific embodiments.

[0020] Example:

[0021] like Figure 1 and Figure 2 As shown, a photovoltaic module battery string correction device 1 of the utility model comprises a first sliding plate 1, a second sliding plate 2, an adjustment mechanism 3 for controlling the spacing between the first sliding plate 1 and the second sliding plate 2 along the X direction, and a guiding mechanism 4 for limiting the movement of the first sliding plate 1 along the X direction, the adjustment mechanism 3 comprises a linear drive member 31 and a connecting rod assembly 32, the linear drive member 31 drives the first sliding plate to move along the X direction, the connecting rod assembly 22 comprises a fixed rotating shaft 221, a pendulum block 222, and a first connecting rod 223a and a second connecting rod 223b with equal arm lengths, the axis of the fixed rotating shaft 221 is along the Z direction and fixed to the center position of the pendulum block 222, one end of the pendulum block 222 is hinged to the middle part of the first sliding plate 1a through the first connecting rod 223a, and the other end of the pendulum block 222 is hinged to the middle part of the second sliding plate 1b through the second connecting rod 223b.

[0022] The moving power of the first sliding plate 1a and the second sliding plate 1b is provided by the linear drive 31, but the second sliding plate 1b is driven by the connecting rod assembly 32. The linear drive 31 here adopts an electric cylinder. The connecting rod assembly 32 takes the fixed rotating shaft 221 as the rotation center, and the two sides always maintain a rotational symmetry relationship during the movement, so when the pendulum block 222 rotates, the first sliding plate 1a and the second sliding plate 1b can move in opposite directions at an equal distance, which is manifested as a clamping and releasing action. In the embodiment, the linear drive 31 directly drives the first sliding plate 1a, but in fact the first sliding plate 1a and the second sliding plate 1b are equivalent components, except for the left and right differences and the setting positions of the return wheel 11 and the paddle 12. The linear drive 31 can also directly drive the second sliding plate 1b.

[0023] The utility model can drive a sliding plate to move through the linear drive member 21, and then drive the other sliding plate to move in the opposite direction through the connecting rod assembly 22, so that the driving force is distributed into two opposite clamping forces, thereby achieving the clamping of the battery string by the first sliding plate and the second sliding plate with a lighter force, thereby preventing the side of the battery string from being clamped and cracked.

[0024] like Figure 1 and Figure 2As shown, a plurality of aligning wheels 11 are arranged along the Y direction on the first sliding plate 1a, and a plurality of paddles 12 are arranged along the Y direction on the second sliding plate 1b. The axes of all aligning wheels 11 are along the Z direction, and the surfaces of all paddles 12 are in the same YZ plane.

[0025] Under operating conditions, the conveying mechanism of the battery string passes between the first sliding plate 1a and the second sliding plate 1b, and the conveying surface of the conveying mechanism is slightly lower than the alignment wheel 11 and the paddle 12, so the alignment wheel 11 and the paddle 12 can contact the edge of the battery string when they are close to each other. The paddle 12 has good elasticity, and when it contacts one side of the battery string, it will undergo elastic deformation outward, which can also play a role in reducing the clamping force. The alignment wheel 11 can roll when it contacts the other side of the battery string, which can reduce scratches when the angle of the battery string is adjusted, thereby protecting the integrity of the battery string. In fact, here, only the sliding plate where the alignment wheel 11 is located is defined as the first sliding plate 1a, and the sliding plate where the paddle 12 is located is defined as the second sliding plate 1b. Because the left-right relative positions of the alignment wheel 11 and the paddle 12 can be interchanged, the left-right relative positions of the first sliding plate 1a and the second sliding plate 1b can be interchanged.

[0026] like Figure 1 and Figure 2 As shown, the guide mechanism 3 is two X-direction slide rails 31 , and two sliders 13 are provided at the lower parts of the first slide plate 1 a and the second slide plate 1 b , and the two sliders 13 slide along the X-direction slide rails 31 respectively.

[0027] The X-direction slide rail 31 cooperates with the slider 13 to enable the first slide plate 1a and the second slide plate 1b to precisely translate along the X direction. In practical applications, the linear guide method is not limited to the guide method of the slide rail and the slider, for example, it can also be a guide method of the slide rail roller, a guide rod slider, etc.

[0028] like Figure 1 and Figure 2 As shown, the linear drive member 21 passes below the center position of the first sliding plate 1a and the second sliding plate 1b.

[0029] In the embodiment, the linear drive 21 directly drives the first sliding plate 1a, so its tail is below the second sliding plate 1b; if the linear drive 21 directly drives the second sliding plate 1b, its tail should be below the first sliding plate 1a. In this way, the linear drive 21 can be hidden under the conveying mechanism, avoiding the correction mechanism 1 from occupying too much of the X-direction length.

[0030] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
