Description

Technical Field

[0001] This utility model belongs to the field of silicon wafer box testing technology, specifically relating to a clamping mechanism for testing photovoltaic silicon wafer boxes. Background Technology

[0002] The clamping mechanism for photovoltaic silicon wafer box inspection is a key piece of equipment in the photovoltaic manufacturing process. It is mainly used to stably clamp the silicon wafer box to ensure the accuracy and safety of the inspection process.

[0003] Existing clamping mechanisms mostly use horizontal clamping when clamping photovoltaic silicon wafer boxes. Since horizontal clamping requires counteracting the weight of the photovoltaic silicon wafer box itself, in order to prevent the photovoltaic silicon wafer box from sliding down and to ensure the stability of clamping and transportation, a large clamping force is generally applied to the outer wall of the photovoltaic silicon wafer box. This can easily cause the photovoltaic silicon wafer box to be deformed by pressure and can also easily damage the photovoltaic silicon wafers inside.

[0004] Therefore, a clamping mechanism for testing photovoltaic silicon wafer boxes is proposed. Summary of the Invention

[0005] This utility model provides a clamping mechanism for testing photovoltaic silicon wafer boxes, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a clamping mechanism for testing photovoltaic silicon wafer boxes, including a bracket; two clamping plates symmetrically slidably disposed inside the bracket; rubber pads respectively disposed on the outer walls of the two clamping plates on opposite sides; a bottom support assembly disposed on the clamping plates; the bottom support assembly includes: a groove and a rotary cylinder disposed on the outer wall of the other side of the clamping plates, the groove being located on one side of the rotary cylinder; a right-angle plate disposed at the rotating end of the rotary cylinder; a support plate disposed on one side of the right-angle plate; an arc portion disposed on the support plate away from the side of the right-angle plate; and a pneumatic assembly disposed at the bottom of the bracket; the pneumatic assembly includes: a piston sleeve disposed at the bottom of the bracket; a spring disposed at the top inside the piston sleeve; a piston disposed at the bottom end of the spring; a pressure rod disposed at the center of the bottom of the piston; and a pneumatic channel disposed between the air outlet of the piston sleeve and the air inlet of the rotary cylinder.

[0007] Furthermore, an electric push rod is provided at the center of one outer wall of the bracket, and a moving stage is fixedly connected to the output end of the electric push rod. A linkage rod is provided between the moving stage and the clamping plate, and a silicon wafer cassette is clamped between the two clamping plates.

[0008] Furthermore, a downward groove is provided at the bottom of the bracket, and an upper through groove is provided at the top of the bracket near the position directly above the downward groove. Two ear plates are symmetrically arranged on the outer side wall of the bracket, and several limiting holes are provided at equal intervals at the top of the bracket near the side of the upper through groove. A limiting plate is provided at the top of the bracket, and the limiting plate and the limiting holes are pin-connected.

[0009] Furthermore, a limit slider is provided at the top of the clamping plate through the upper through groove, and a guide slider is provided at the bottom of the clamping plate near the inside of the lower groove.

[0010] By adopting the above technical solution, the movement position of the limiting slider is limited, thereby avoiding excessive pressure from the clamping plate on the silicon wafer box, which could cause deformation and damage.

[0011] Furthermore, the cross-section of the limiting slider is T-shaped, and the limiting plate is located on the linear motion trajectory of the limiting slider;

[0012] By adopting the above technical solution, the T-shape ensures stable movement of the device within the upper channel.

[0013] Furthermore, the piston performs a piston-like motion inside the piston sleeve;

[0014] By adopting the above technical solution, the piston movement ensures the sealing of the piston's vertical movement inside the piston sleeve, thus preventing gas leakage.

[0015] Furthermore, the movable platform and the support are slidably connected, and both the movable platform and the clamping plate are rotatably connected to the linkage rod;

[0016] By adopting the above technical solution, the linkage rod between the moving platform and the clamping plate can be adjusted in angle as the position changes through rotational connection, thereby using the moving platform to pull the two clamping plates to move synchronously in opposite directions.

[0017] Furthermore, the pneumatic channel adopts a bellows, and the pneumatic chambers of the rotary cylinder and the piston sleeve are both connected to the bellows.

[0018] By adopting the above technical solution, the bellows itself has the ability to deform adaptively, and air flow is achieved through the bellows, so that the air between the rotary cylinder and the piston sleeve flows to each other, thereby changing the air pressure at the output end and driving the output end.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model, through the cooperation of the bottom support component and the pneumatic component, can support the bottom of the silicon wafer box in a horizontal clamping state, ensuring the stability of the silicon wafer box during the transfer process, without the need for an additional power source, reducing the device's dependence on electricity, and can provide additional support for the two clamping plates to horizontally clamp the silicon wafer box, avoiding the need for greater clamping force when the silicon wafer box is horizontally clamped, and preventing the outer shell of the silicon wafer box from being deformed and damaged by pressure.

[0021] 2. This utility model limits the movement of the clamping plate by limiting the position of the clamping plate, which can ensure that after the rubber pad is squeezed and deformed by the outer surface of the silicon wafer box, the clamping plate does not come into contact with the outer surface of the silicon wafer box, thereby avoiding contact between the clamping plate and the silicon wafer box and preventing the clamping plate from excessively clamping the silicon wafer box and causing deformation of its outer surface.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] Reference Figure 1-4 This utility model embodiment proposes a clamping mechanism for testing photovoltaic silicon wafer cassettes, including a bracket 1. Two clamping plates 2 are symmetrically slidably connected inside the bracket 1. A silicon wafer cassette 9 is clamped between the two clamping plates 2. Two sets of bottom support components 3 are symmetrically arranged on the outer walls of the two clamping plates 2 facing opposite directions. The bottom support component 3 includes a groove 31 opened in one side wall of the clamping plate 2. A rotary cylinder 32 is embedded in one side of the outer wall of the clamping plate 2 near the groove 31. A right-angle plate 33 is provided at the rotating conveying end of the rotary cylinder 32. A support plate 34 is provided at one side end of the right-angle plate 33. An arc portion 35 is provided on the side end of the support plate 34 away from the right-angle plate 33.

[0033] Specifically, the four sets of bottom support components 3 can support the bottom of the silicon wafer box 9, ensuring the stability of the silicon wafer box 9 during the transfer process, providing additional support for the two clamping plates 2 to horizontally clamp the silicon wafer box 9, avoiding the need for greater clamping force when the silicon wafer box 9 is horizontally clamped, and preventing the outer shell of the silicon wafer box 9 from being deformed and damaged by pressure.

[0034] The bottom of the bracket 1 is provided with a piston sleeve 41 of the pneumatic assembly 4. A spring 42 is provided at the top inside the piston sleeve 41, and a piston 43 is provided at the bottom end of the spring 42. The piston 43 performs piston-like movement inside the piston sleeve 41. The piston-like movement ensures the sealing of the piston 43's lifting and lowering movement inside the piston sleeve 41 and prevents gas leakage. A pressure rod 44 is provided at the center of the bottom of the piston 43. An air outlet is provided on the outer wall of one side of the piston sleeve 41 near the top. A pneumatic channel 5 is provided between the rotary cylinder 32 and the piston sleeve 41. The pneumatic channel 5 is made of a bellows. The pneumatic chambers of the rotary cylinder 32 and the piston sleeve 41 are connected to the bellows. The bellows' own tensile deformation ability allows it to deform adaptively, and airflow is achieved through the bellows. This allows the air between the rotary cylinder 32 and the piston sleeve 41 to flow to each other, thereby changing the air pressure at the output end and driving the output end.

[0035] Specifically, power transmission is achieved through pneumatic component 4, eliminating the need for an additional power source. During clamping, the clamping structure must descend to the horizontal outer side of the silicon wafer cassette 9. As the support 1 moves downwards, the pressure rod 44 first contacts the working platform where the silicon wafer cassette 9 is placed. At this point, under pressure, the pressure rod 44 pushes the piston 43 upwards. The piston 43 moves upwards piston-like inside the piston sleeve 41, compressing the spring 42. The air inside the piston sleeve 41, under compression, enters the rotary cylinder 32 through the pneumatic channel 5. After the internal air pressure of the rotary cylinder 32 increases, the output end of the rotary cylinder 32 drives the right-angle plate 33 to rotate. When the right-angle plate 33 rotates upward, it is stored in the groove 31 and horizontally clamps the silicon wafer box 9 through the two clamping plates 2. Then, the silicon wafer box 9 is clamped away from the working platform. Under the action of the spring 42's rebound force, the spring 42 pushes the piston 43 to move downward. Negative pressure is generated inside the piston sleeve 41, and the air in the rotary cylinder 32 is drawn back into the piston sleeve 41. The output end of the rotary cylinder 32 drives the right-angle plate 33 to reset. The right-angle plate 33 rotates downward, and the support plate 34 and the arc part 35 on one side of the right-angle plate 33 move in a synchronous circular motion until the arc part 35 contacts the bottom of the silicon wafer box 9, thus supporting the silicon wafer box 9.

[0036] A drive unit is provided at the center of one outer wall of the bracket 1. The drive unit can be an electric push rod 6 or a cylinder that does not require electricity. The electric push rod 6 in the drive unit is fixedly connected to a moving platform 7 through its output end on one side. A linkage rod 8 is movably connected between the moving platform 7 and the clamping plate 2. The moving platform 7 and the bracket 1 are slidably connected. The moving platform 7 and the clamping plate 2 are rotatably connected to the linkage rod 8. The sliding connection allows the moving platform 7 to move linearly, and the rotatable connection allows the linkage rod 8 between the moving platform 7 and the clamping plate 2 to adjust its angle as the position changes. Thus, the moving platform 7 pulls the two clamping plates 2 to move synchronously in opposite directions.

[0037] Specifically, the moving stage 7 is driven to slide by the electric push rod 6. With the connection of the linkage rod 8, the two clamping plates 2 can be pulled to move synchronously in opposite directions, thereby adjusting the distance between the two clamping plates 2 to achieve the purpose of horizontally clamping the silicon wafer box 9, which facilitates the transfer of the silicon wafer box 9 during the inspection operation.

[0038] Example 2

[0039] Reference Figure 1-2Based on the above embodiments, this utility model embodiment also proposes a clamping mechanism for testing photovoltaic silicon wafer boxes, including a bracket 1 and a clamping plate 2 that slides inside it. A downward groove 11 is provided at the bottom of the inside of the bracket 1, and an upper through groove 12 is provided at the top of the bracket 1 near the position directly above the downward groove 11. Two ear plates 13 are symmetrically arranged on the outer side wall of the bracket 1, and a plurality of limiting holes 14 are equally spaced at the top of the bracket 1 near the side of the upper through groove 12. A limiting plate 15 is provided at the upper position of the bracket 1, and the limiting plate 15 and the limiting holes 14 are pin-connected.

[0040] A rubber pad 23 is provided on one side of the outer wall of the clamping plate 2, and a limiting slider 21 is provided on the top of the clamping plate 2 through the upper through groove 12. The cross-section of the limiting slider 21 is T-shaped, which makes it move stably in the upper through groove 12. The limiting plate 15 is located on the linear movement trajectory of the limiting slider 21. By interfering with the movement trajectory of the limiting slider 21 through the limiting plate 15, the movement position of the limiting slider 21 is limited, thereby avoiding the clamping plate 2 from excessively squeezing the silicon wafer box 9 and causing deformation and damage. A guide slider 22 is provided at the bottom of the clamping plate 2 near the inside of the lower groove 11.

[0041] Specifically, the limiting plates 15 are pinned to the top of the bracket 1 through the limiting holes 14 at different positions. The distance between the two limiting plates 15 can be adjusted according to the width of the silicon wafer box 9, so that the movement of the limiting slider 21 after the limiting plates 15 are pinned can limit the movement of the clamping plate 2. This ensures that after the rubber pad 23 is squeezed and deformed by the outer surface of the silicon wafer box 9, the clamping plate 2 does not contact the outer surface of the silicon wafer box 9, thereby avoiding contact between the clamping plate 2 and the silicon wafer box 9 and preventing the clamping plate 2 from excessively clamping the silicon wafer box 9 and causing deformation of its outer surface. The deformed rubber pad 23 increases the friction with the silicon wafer box 9, so that the silicon wafer box 9 can be horizontally clamped and transported.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
