Description

Technical Field

[0001] The utility model relates to the technical field of solar cell production, in particular to a photovoltaic sheet straightening device and a photovoltaic sheet production line. Background Art

[0002] With the rapid development of the photovoltaic solar cell industry, screen printing will more or less have yield efficiency inspections. During the inspection process, it is necessary to conduct a cross-cutting experiment on the light injection, which involves placing the photovoltaic cells from the connection between the sintering furnace and the light injection box. During the placement of the photovoltaic cells, there may be a situation where the photovoltaic cells are not aligned properly. If no intervention is performed, a large number of cards will appear on the light injection box machine, which may easily burn the photovoltaic cells.

[0003] In the case of photovoltaic cells not being aligned, the prior art generally uses an image detector to detect whether the photovoltaic cells are skewed. If the detector sounds an alarm, it means that there is a photovoltaic cell that is not aligned, and then the staff manually straightens the photovoltaic cell to ensure that the photovoltaic cell accurately enters the light injection box. However, the production line of photovoltaic cells is fast, and manually straightening the photovoltaic cell affects the transportation of the production line, thereby affecting the production of photovoltaic cells.

[0004] Therefore, the prior art needs to be improved. Utility Model Content

[0005] The technical problem to be solved by the utility model is that manual straightening of photovoltaic cells in the prior art affects production efficiency. The utility model aims to provide a photovoltaic cell straightening device and a photovoltaic cell production line, which adopt corresponding technical means, have the effect of mechanically straightening photovoltaic cells and have higher production efficiency.

[0006] The utility model is realized by the following technical solutions:

[0007] In a first aspect, the utility model provides a photovoltaic panel straightening device.

[0008] Includes detectors to detect the passage of photovoltaic panels,

[0009] It includes a straightening piece for clamping the photovoltaic sheet, and two straightening pieces are arranged on both sides of the photovoltaic sheet assembly line.

[0010] It also includes a driver electrically connected to the detector, and the driver is connected to the straightening member.

[0011] In the above technical solution, the photovoltaic sheet straightening device consists of three parts: a detector, a straightening member and a driver. The detector is used to detect whether a photovoltaic sheet passes by, and the driver is used to drive two straightening members to clamp the photovoltaic sheet once, and then straighten the photovoltaic sheet through the clamping of the photovoltaic sheet. Since mechanical straightening is used instead of manual straightening, the production line of photovoltaic sheets does not need to reduce the transportation speed, and thus does not affect the production efficiency of photovoltaic sheets.

[0012] Furthermore, in the utility model, a mounting plate is also included, the driver includes a fixed pulley arranged on the mounting plate, the fixed pulley sleeve is provided with a belt loop, the belt segment of the belt loop moving toward or away from the assembly line is connected to the straightening member, the two straightening members move in mirror images of each other, and the fixed pulley transmission is connected to a motor.

[0013] Furthermore, in the utility model, the above-mentioned mounting plate is provided with a guide rail, and the guide rail is provided with a slider moving along the guide rail, and the slider is connected to the straightening member.

[0014] Furthermore, in the present invention, the above-mentioned sliding block is connected with a supporting member, and the supporting member is connected to the straightening member.

[0015] Furthermore, in the present invention, the belt loop is configured as a rectangular belt loop.

[0016] Furthermore, in the present invention, the fixed pulley is provided with teeth, and the belt loop is configured as a toothed belt.

[0017] Furthermore, in the present invention, the above-mentioned motor is configured as a stepping motor.

[0018] Furthermore, in the present invention, the above-mentioned straightening member is provided with a roller abutting against the side of the photovoltaic panel.

[0019] Furthermore, in the present invention, the detector is configured as an infrared reflection sensor.

[0020] In a second aspect, the utility model further provides a photovoltaic sheet production line, including a photovoltaic sheet straightening device, including an assembly line for transporting photovoltaic sheets, wherein the photovoltaic sheet straightening device is connected to the assembly line.

[0021] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0022] The photovoltaic sheet straightening device provided by the utility model comprises three parts: a detector, a straightening member and a driver. When the detector detects that a photovoltaic sheet passes through the production line, the driver controls two straightening members to quickly move closer to the two sides of the photovoltaic sheet. After clamping the photovoltaic sheet once, the driver controls the two straightening members to quickly move away from the two sides of the photovoltaic sheet, without affecting the transportation of the photovoltaic sheet. By using mechanical straightening instead of manual straightening, the production line for producing photovoltaic sheets does not need to reduce the transportation speed, thereby not affecting the production efficiency of the photovoltaic sheets.

[0023] The utility model also provides a photovoltaic sheet production line, including an assembly line for transporting photovoltaic sheets, and a photovoltaic sheet straightening device is also installed on the assembly line. The photovoltaic sheet straightening device straightens each photovoltaic sheet once, ensuring that all photovoltaic sheets enter the light injection box with accurate posture, avoiding the occurrence of a large number of cards and photovoltaic sheets burning. The accident rate is reduced, and the safety of photovoltaic sheet production is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] This embodiment 1 provides a photovoltaic panel straightening device, such as Figure 1-Figure 2 As shown, the specific structure is described as follows.

[0036] Please refer to Figure 1 and Figure 2 As shown, the photovoltaic panel straightening device of this embodiment is mainly composed of three parts: a detector 1, a straightening member 2 and a driver 3. The detector 1 is used to detect whether there is a photovoltaic panel passing by, and the driver 3 is used to drive the two straightening members 2 to clamp the photovoltaic panel once, thereby straightening the photovoltaic panel by clamping the photovoltaic panel.

[0037] Further, combined with Figure 1 As shown, the photovoltaic panel straightening device also includes a mounting plate 4, which is used to provide a mounting position for other components. The mounting plate 4 is a rectangular aluminum alloy plate, which has the characteristics of light weight and high strength. The mounting plate 4 is fixed on the support frame of the assembly line, and the mounting plate 4 is located below the surface belt of the assembly line.

[0038] Combination Figure 1 As shown, the detector 1 adopts the infrared reflection type sensor of the prior art, and the detector 1 is installed at the top center of the mounting plate 4, combined with Figure 3 As shown, the detector 1 is located between two assembly line belts. When the assembly line belt carries photovoltaic panels passing through the detector 1, the infrared rays emitted vertically upward by the detector 1 will be reflected back by the surface of the photovoltaic panels, thereby detecting the passing of photovoltaic panels.

[0039] In some implementations of this embodiment, please refer to Figure 1 and Figure 2 The driver 3 includes four fixed pulleys 301 and a belt loop 302. The four fixed pulleys 301 are installed at the four corners of the mounting plate 4. The belt loop 302 is sleeved on the four fixed pulleys 301. The belt loop 302 is shaped into a rectangle by the four fixed pulleys 301. The motor is also installed on the mounting plate 4. The motor drives one of the fixed pulleys 301 to rotate through a gear, chain or belt. The motor adopts a stepping motor, which has the advantage of precise speed control and is convenient for controlling the forward or reverse rotation of the belt loop 302.

[0040] It should be noted that the fixed pulley 301 is provided with teeth, and the belt loop 302 is configured as a toothed belt. The teeth of the toothed belt can mesh with the teeth of the fixed pulley 301, and the belt loop 302 moves more accurately, reducing the occurrence of slippage, and thus the photovoltaic panel straightening device is more accurately straightened.

[0041] For further information, please refer to Figure 1 and Figure 2 As shown, the straightening member 2 is two long aluminum alloy metal strips, and the straightening member 2 and the photovoltaic panels on the assembly line are at the same level. A support member 6 is connected to the bottom of the straightening member 2, and the support member 6 is composed of three long strips. Two guide rails 5 are fixed at the bottom of the mounting plate 4, and the guide rails 5 are perpendicular to the direction of the assembly line. One guide rail 5 is located on the upstream side, and the other guide rail 5 is located on the downstream side. A slider 501 is installed on the guide rail 5, and the slider 501 can slide smoothly along the guide rail 5.

[0042] Furthermore, combined Figure 1 As shown, the extending direction of the guide rail 5 and the rectangular belt loop 302 are directed toward or away from the belt segment moving in the assembly line (i.e. Figure 1 The longer band segment) is parallel to Figure 1 The support member 6 on the left side is fixedly connected to the longer belt loop 302 on the left side, and the support member 6 on the right side is fixedly connected to the longer belt loop 302 on the right side. When the motor drives the fixed pulley 301 to rotate, the belt loop 302 also moves. When the motor drives the belt loop 302 to move counterclockwise for a certain distance, the two straightening members 2 move toward the middle to clamp once, and then the motor drives the belt loop 302 to move clockwise for a certain distance, and the two straightening members 2 move in a direction away from the middle, so that the two straightening members 2 move in a mirror-image manner, and the straightening effect is better.

[0043] In some implementations of this embodiment, combined with Figure 2 As shown, two rollers 201 are installed on the top of each straightening member 2, and the rollers 201 can roll freely. When the straightening members 2 are clamped together, the rollers 201 contact the two sides of the photovoltaic sheet, and the rollers 201 do not affect the continuous movement of the photovoltaic sheet on the assembly line, and can straighten the position of the photovoltaic sheet at the same time.

[0044] Example 2

[0045] This embodiment 2 provides a photovoltaic production line, such as Figure 3 As shown, the specific structure is described as follows.

[0046] Combination Figure 3 As shown, the photovoltaic sheet production line includes two assembly lines for transporting photovoltaic sheets, and the two assembly lines hold up the photovoltaic sheets and move them. The photovoltaic sheet straightening device is installed on the assembly line support frame, the straightening member 2 is located on both sides of the photovoltaic sheet assembly line, and the detector 1 is located between the two assembly lines.

[0047] The working principle of the photovoltaic sheet straightening device and photovoltaic sheet production line of the utility model is as follows:

[0048] The photovoltaic sheet is lifted and moved by two assembly lines. Since the detector 1 and the controller of the driver 3 are electrically connected, the detector 1 sends a signal to the controller when it detects that a photovoltaic sheet has passed. The controller controls the motor to immediately drive the fixed pulley 301 to rotate once, and then the belt loop 302 rotates counterclockwise for a distance, and then the two straightening members 2 quickly approach the two sides of the photovoltaic sheet, clamping the photovoltaic sheet once, and achieving the effect of position straightening. Then the motor immediately drives the fixed pulley 301 to rotate in the opposite direction once, and the belt loop 302 rotates clockwise for a distance, controlling the two straightening members 2 to quickly move away from the two sides of the photovoltaic sheet.

The mounting plate 4 is provided with a guide rail 5, and the guide rail 5 is provided with a slider 501 moving along the guide rail 5, and the slider 501 is connected to the straightening member 2. The slider 501 is connected to a support member 6, and the support member 6 is connected to the straightening member 2. The belt loop 302 is configured as a rectangular belt loop 302.
