Description

Technical Field

[0001] This utility model relates to the field of clamping fixtures, specifically to a clamping fixture for coating solar backsheets. Background Technology

[0002] As an important component of solar cell modules, the solar backsheet coating is crucial for ensuring the performance and lifespan of solar cell modules. Effective protection extends the lifespan of solar cell modules, thereby improving the overall photoelectric conversion efficiency.

[0003] The existing clamping fixtures still have some problems when in use: Most existing clamping fixtures achieve the movement of the clamping plate by connecting the clamping plate and the outer ring of the threaded rod with threads of different directions, so that the clamping plate can clamp the two sides of the solar panel and then process the back of the solar panel. However, after a long period of use, the threaded connection between the clamping plate and the threaded rod may get stuck, causing the clamping plate to move unsmoothly, thus affecting the clamping of the solar panel.

[0004] Therefore, it is necessary to invent a clamping fixture for solar backsheet coating to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping fixture for coating solar backsheets, in order to solve the problem mentioned in the background art that most existing clamping fixtures achieve the movement of the clamping plate by connecting the clamping plate and the outer ring of the threaded rod with threads of different directions, so that the clamping plate can clamp the two sides of the solar panel and then process the back of the solar panel. However, after a long period of use, the threaded connection between the clamping plate and the threaded rod may get stuck, resulting in the clamping plate not moving smoothly, thus affecting the clamping of the solar panel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for solar backsheet coating, comprising a mounting frame, wherein the mounting frame is internally provided with an oil chamber and a movable chamber, and the top of the oil chamber is provided with an oil filling port; a motor is fixedly connected to the side wall of the mounting frame, and the output shaft of the motor is driven by a threaded rod, and the threaded rod is rotatably connected to the inner wall of the movable chamber; and further comprising:

[0007] The sealing assembly has an oil outlet connected to the oil chamber and the movable chamber. A plug is installed inside the oil outlet, and a vertical rod is fixedly installed on the top of the plug. A disc is fixedly installed on the top of the vertical rod, and the disc is elastically connected to the mounting frame by a spring.

[0008] The ejector assembly has a threaded connection between the threaded rod and the threaded groove reserved inside the movable block, and the movable block has an oil storage cavity reserved inside, and the inner wall of the oil storage cavity is fixedly connected to a pointed cone block through a connecting block.

[0009] The clamping assembly has a clamping plate fixedly connected to the lower end of the movable block via a short rod.

[0010] Preferably, the oil outlet is inverted conical in shape, and the inner wall of the oil outlet is in contact with the outer wall of the plug to achieve a sliding connection. Furthermore, both the upper and lower ends of the plug protrude from the upper and lower openings of the oil outlet, which facilitates the movement of the conical block to lift the plug, creating a gap between the plug and the oil outlet, thus allowing the lubricating oil inside the oil cavity to leak out.

[0011] Preferably, the spring is movably mounted on the outer ring of the upright, and the upper and lower ends of the spring are respectively fixedly connected to the disc and the top wall of the mounting frame, so that the plug is tightly matched and connected to the oil outlet under the elastic force applied by the spring.

[0012] Preferably, the upper tip of the cone block is attached to the top wall of the movable cavity to achieve a sliding connection, and the outer surface of the cone block is a smooth surface. Furthermore, the outer surface of the cone block is attached to the outer wall of the block that protrudes from the lower opening of the oil outlet to achieve a sliding connection, which facilitates the cone block to press against the block during its movement to achieve oil discharge.

[0013] Preferably, the outer wall of the short rod is attached to the inner wall of the groove opened at the bottom of the mounting frame to achieve a sliding connection, and the groove is connected to the movable cavity to ensure the stability of the clamping plate movement.

[0014] Preferably, the outer ring of the threaded rod is provided with two symmetrical threads with opposite directions, and the two threads are respectively connected to two movable blocks inside the movable cavity to achieve threaded connection. When the threaded rod rotates, the two clamping plates move towards or away from each other to clamp and release the solar panel to be processed.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model uses a starting motor to drive the rotation of the threaded rod, causing the two movable blocks to move towards each other until the pointed cone block fixedly connected inside the movable block moves and lifts the block during the movement. The lubricating oil inside the oil chamber leaks out through the gap between the block and the oil outlet and drips into the oil storage chamber. The oil storage chamber is connected to the threaded groove reserved inside the movable block. In this way, when the rotation of the threaded rod causes the movable block that is threadedly connected to the threaded rod to change position, the lubricating oil in the oil storage chamber inside the movable block is evenly coated on the outer ring of the threaded rod in the rotating state, which makes the subsequent threaded connection between the movable block and the threaded rod smoother.

[0017] 2. The two oil outlets are located close to each other, so that the two clamps will not accidentally open the oil outlets when clamping the two sides of a solar panel of a certain size. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-4 The fixture shown is a clamping tool for coating solar backsheets, including a mounting frame 1. The mounting frame 1 has an oil chamber 2 and a movable chamber 3 inside, and the top of the oil chamber 2 has an oil filling port 4. A motor 8 is fixedly connected to the side wall of the mounting frame 1, and the output shaft of the motor 8 is driven by a threaded rod 9, which is rotatably connected to the inner wall of the movable chamber 3. The fixture also includes:

[0027] The sealing component 5 has an oil outlet 501 that connects the oil chamber 2 and the movable chamber 3. A plug 502 is installed inside the oil outlet 501, and a vertical rod 503 is fixedly installed on the top of the plug 502. A disc 504 is fixedly installed on the top of the vertical rod 503, and the disc 504 is elastically connected to the mounting frame 1 by a spring 505.

[0028] The ejector assembly 6 and the threaded rod 9 are threadedly connected to the threaded groove 603 reserved inside the movable block 601. The movable block 601 has an oil storage cavity 602 reserved inside, and the inner wall of the oil storage cavity 602 is fixedly connected to the pointed cone block 604 through the connecting block 605.

[0029] The clamping assembly 7 has a clamping plate 702 fixedly connected to the lower end of the movable block 601 via a short rod 701.

[0030] The oil outlet 501 is inverted cone shape, and the inner wall of the oil outlet 501 and the outer wall of the plug 502 are attached to each other to achieve a sliding connection. The upper and lower ends of the plug 502 protrude from the upper and lower openings of the oil outlet 501, which facilitates the movement of the cone block 604 to lift the plug 502, so that there is a gap between the plug 502 and the oil outlet 501, which facilitates the leakage of lubricating oil inside the oil cavity 2.

[0031] Spring 505 is movably mounted on the outer ring of upright 503, and the upper and lower ends of spring 505 are fixedly connected to disc 504 and the top wall of mounting frame 1, respectively. Under the elastic force applied by spring 505, the plug 502 is tightly matched and connected to oil outlet 501.

[0032] The upper tip of the cone block 604 is attached to the top wall of the movable cavity 3 to achieve a sliding connection. The outer surface of the cone block 604 is a smooth surface. The outer surface of the cone block 604 is attached to the outer wall of the block 502 that protrudes from the lower opening of the oil outlet 501 to achieve a sliding connection. This facilitates the cone block 604 to press against the block 502 during its movement to achieve oil discharge.

[0033] The outer wall of the short rod 701 is attached to the inner wall of the groove opened at the bottom of the mounting frame 1 to achieve a sliding connection, and the groove is connected to the movable cavity 3 to ensure the stable movement of the clamping plate 702.

[0034] The outer ring of the threaded rod 9 is provided with two symmetrical threads with opposite directions, and the two threads are respectively connected to the two movable blocks 601 inside the movable cavity 3 to achieve threaded connection. When the threaded rod 9 rotates, the two clamping plates 702 move towards each other or away from each other to clamp and release the solar panel to be processed.

[0035] Working principle: When using a clamping fixture for solar panel backsheet coating, the motor 8 is first started, driving the threaded rod 9 connected to the output shaft of the motor 8 to rotate. This causes the movable block 601, which is threadedly connected to the threaded rod 9, to slide against the inner wall of the movable cavity 3. The movable block 601 and the outer ring of the threaded rod 9 are provided with two symmetrical threads with opposite directions to achieve threaded connection. When the threaded rod 9 rotates, the two clamping plates 702 move towards or away from each other, clamping and releasing the solar panel to be processed. After prolonged use, when the threaded connection between the movable block 601 and the threaded rod 9 requires lubrication, the rotation of the threaded rod 9 is started, causing the two movable blocks 601 to slide against the inner wall of the movable cavity 3. 01 The opposing movement continues until the pointed cone block 604, which is fixedly connected inside the movable block 601, lifts the blocking block 502 during the movement. This creates a gap between the blocking block 502 and the oil outlet 501, allowing the lubricating oil inside the oil chamber 2 to leak out and drip into the oil storage chamber 602 reserved inside the movable block 601. The oil storage chamber 602 is connected to the threaded groove 603 reserved inside the movable block 601. Thus, when the threaded rod 9 rotates and causes the movable block 601, which is threadedly connected to the threaded rod 9, to change position, the lubricating oil in the oil storage chamber 602 inside the movable block 601 is evenly coated on the outer ring of the rotating threaded rod 9, making the subsequent threaded connection between the movable block 601 and the threaded rod 9 smoother.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
