Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic silicon wafers, and in particular to a photovoltaic silicon wafer material box with visually adjustable size. Background Art

[0002] With the advancement of photovoltaic technology, the silicon wafer sizes used in photovoltaic modules have become increasingly diverse and standardized. However, during the manufacturing process of photovoltaic modules, silicon wafers of different shapes and sizes must be frequently switched. Since each wafer size requires a corresponding size magazine, a large number of different magazines must be prepared in advance, which is costly and requires a lot of storage space.

[0003] In order to solve the problem of incompatibility of material boxes, an idea has been proposed in the prior art, that is, several baffles on the photovoltaic silicon wafer material box used to clamp the silicon wafers are set to be movable relative to the bottom plate, and the several baffles are moved closer or farther away from each other to adjust the size of the accommodating space, thereby being suitable for photovoltaic silicon wafers of different sizes.

[0004] However, current photovoltaic silicon wafer magazines typically lack size identification or other features to assist with size adjustment. Switching between different wafer types or specifications requires operators to compare measurements with actual wafers or use a ruler. This process is time-consuming and prone to measurement errors. Adjustment consistency between different baffles is poor, resulting in a mismatch between the adjusted storage space and the size of the photovoltaic silicon wafers. This can cause the photovoltaic silicon wafers to scrape against the magazine or become misplaced, leading to hidden cracks or fragmentation in the photovoltaic silicon wafers. Utility Model Content

[0005] The purpose of the present utility model is to provide a photovoltaic silicon wafer material box with visually adjustable size, which can visually adjust the size with high adjustment consistency. The adjusted size matches the size of the photovoltaic silicon wafer, preventing the photovoltaic silicon wafer from scratching the material box or being placed in a disorderly manner, thereby avoiding hidden cracks or breakage of the photovoltaic silicon wafer.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] Example 1

[0047] See Figure 1 This embodiment provides a photovoltaic silicon wafer material box with visual size adjustment, including a supporting structure 1, a positioning structure, a stop structure and an identification structure 30.

[0048] Specifically, the support structure 1 includes a hollow area 11 and an outer edge plate 12 disposed around the periphery of the hollow area 11. The hollow area 11 is a square structure. The outer edge plate 12 is a "U"-shaped plate disposed around the periphery of the hollow area 11 and has a square cross-section. The outer edge plate 12 is made of aluminum alloy or steel. This application does not impose specific restrictions on the size and material of the outer edge plate 12, and they can be adjusted based on design requirements.

[0049] To ensure accurate positioning of the photovoltaic silicon wafer cassette, symmetrical positioning grooves 13 are provided on opposite sides of the outer edge plate 12. These positioning grooves 13 are designed to cooperate with positioning structures on other equipment to ensure that the photovoltaic silicon wafer cassette is positioned within the device. For example, the positioning grooves 13 can be used to cooperate with positioning pegs on a dicing machine to ensure the photovoltaic silicon wafer cassette is accurately positioned on the dicing machine. This is a conventional structure.

[0050] To facilitate manual handling of the photovoltaic silicon wafer box, the photovoltaic silicon wafer box also includes a hand-held structure, which includes two handles 20 arranged on opposite sides of the support structure 1. In this embodiment, the handles 20 are supported by stainless steel and fixed to the outer edge plate 12 by screws. This is a conventional structure.

[0051] The adjustment structure is arranged one-to-one at the four corners of the outer edge plate 12, and the adjustment structure includes at least two fixed positions, and the at least two fixed positions are arranged at intervals on the virtual line connecting the midpoint of the hollow area 11 and the vertex of the corresponding corner.

[0052] The stop structures are arranged one-to-one on the positioning structure, and the four sets of stop structures enclose a storage space. Under the action of the positioning structure, the stop structures can be selectively moved closer to or farther from the midpoint of the hollow area 11 and fixed to one of the at least two fixed positions to reduce or expand the storage space. It is worth noting that the fixed positions are set according to the different sizes of photovoltaic silicon wafers to limit the size of the storage space.

[0053] In this embodiment, the positioning structure includes two positioning units 2a, which are symmetrically arranged on both sides of the virtual line. The stop structure includes two baffles 3, which are arranged one-to-one on the corresponding positioning units 2a. The identification structure 30 is arranged on at least one side of the positioning unit 2a in the width direction.

[0054] In some optional embodiments, the baffle 3 is made of aluminum alloy and is perpendicular to the outer edge plate 12. A polytetrafluoroethylene layer (unnumbered) is adhered to the surface of the baffle 3, thereby reducing the friction coefficient between the baffle 3 and the edge of the photovoltaic silicon wafer and avoiding wear and breakage of the photovoltaic silicon wafer.

[0055] In detail, the positioning unit 2a includes a guide groove 2a1, through holes 2a2 provided on both sides of the guide groove 2a1 in the width direction, and a fixing member (not shown) passing through the through hole 2a2. The through hole 2a2 extends along the length direction of the guide groove 2a1, and the fixing member is used to connect the baffle 3 and the outer edge plate 12. The corner has two vertically connected sides. The length direction of the guide groove 2a1 is perpendicular to one side of the corresponding corner, and the length directions of the two guide grooves 2a1 symmetrically arranged along the virtual line are perpendicular. In this embodiment, the fixing member is specifically a bolt. The head end of the bolt is located below the guide groove 2a1, and the tail end passes through the through hole 2a2 to be threadedly connected to the bottom of the baffle 3.

[0056] It should be noted that the length direction of the guide groove 2a1 is as follows: Figure 1 As shown by the arrow a, the width direction of the adjustment unit 2a is as follows: Figure 1 As shown by arrow b.

[0057] The identification structure 30 is set on the outer edge plate 12, and is used to identify the size of the accommodation space corresponding to at least two fixed positions of the adjustment structure, that is, when the adjustment structure is at any fixed position, the accommodation space enclosed by the stop structure corresponds to the size that can accommodate the photovoltaic silicon wafer.

[0058] Specifically, the marking structure 30 includes scale lines and / or scale values ​​recessed inward from the top surface of the outer edge plate 12. By configuring the scale lines and scale values ​​as recessed inward, wear and tear can be avoided over time. Of course, in other embodiments, the marking structure 30 may also be configured as a protrusion outward from the top surface of the outer edge plate 12. This is not specifically limited in this application.

[0059] In this embodiment, the identification structure 30 includes scale lines and scale values. The scale lines are arranged on both sides of the guide groove 2a1 in the width direction, and the scale lines on the adjacent sides of the two guide grooves 2a1 on the same side of the outer edge plate 12 are connected. The scale values ​​are arranged between the two guide grooves 2a1 on the same side of the outer edge plate 12 and are located above or below the corresponding scale lines. The scale values ​​are used to identify the side length of the photovoltaic silicon wafer corresponding to the side.

[0060] To prevent contact between the supporting structure 1 and the photovoltaic silicon wafers, which could cause wear and tear, the photovoltaic silicon wafer magazine also includes a tray 4. Tray 4 is positioned above the supporting structure 1 and within the storage space. Tray 4 comprises a plate 41, an upper anti-collision pad 42 positioned above plate 41, and a lower anti-collision pad 43 positioned below plate 41. In this embodiment, tray 4 is made of aluminum alloy or plastic, while upper and lower anti-collision pads 42 and 43 are made of foam.

[0061] In detail, the plate body 41 includes a main body 411, a lap portion 412 extending outward from the four top corners of the main body 411, and a through hole 413 arranged on the main body 411. The main body 411 is located directly above the hollow area 11 and closes the hollow area 11. In the height direction, the positive projection of at least part of the lap portion 412 overlaps with the outer edge plate 12.

[0062] The through holes 413 are provided to facilitate taking out the tray 4. In this embodiment, the through holes 413 are circular in shape and are provided in four numbers. The four through holes 413 are centrally symmetrically distributed along the midpoint of the tray 4. The present application does not specifically limit the shape, number, and distribution position of the through holes 413.

[0063] Bosses 5 are provided at the four corners of the hollow area 11, and the upper surface of the bosses 5 is higher than the upper surface of the outer edge plate 12. Placing the bosses 5 at the corners of the hollow area 11 and making the upper surface of the bosses 5 higher than the upper surface of the outer edge plate 12 can effectively raise the height of the photovoltaic silicon wafer, thereby ensuring that the photovoltaic silicon wafer does not directly contact the supporting structure 1, thereby reducing the risk of damage to the photovoltaic silicon wafer and protecting the integrity and quality of the photovoltaic silicon wafer.

[0064] In this embodiment, in order to improve the safety of use, the top corners of the outer edge plate 12 and the top corners of the overlapping portion 412 are both set to be chamfered.

[0065] Taking this embodiment as an example, when in use, the fixing between the baffle 3 and the outer edge plate 12 is released by loosening the fixing parts, and according to the size of the photovoltaic silicon component, the baffle 3 is moved along the length direction of the guide groove 2a1 until the inner wall of the baffle 3 is flush with the corresponding scale line, and then the fixing parts are tightened to fix the relative position between the baffle 3 and the outer edge plate 12, so that the size of the accommodating space is adapted to the size of the photovoltaic silicon component.

[0066] Example 2

[0067] See Figure 2This embodiment provides a photovoltaic silicon wafer material box. Like the first embodiment, the photovoltaic silicon wafer material box can also be visually adjusted in size. The structure of the photovoltaic silicon wafer material box in this embodiment is similar to that of the photovoltaic silicon wafer material box in the first embodiment, with the difference that: a limiting card slot 2a3 is provided on the side of the guide groove 2a1 in the width direction, away from the other guide groove 2a1 arranged symmetrically along the virtual line. The limiting card slot 2a3 is formed by protruding outward from the guide groove 2a1 along the width direction of the guide groove 2a1 and is arranged one-to-one with the fixed position. The two through holes 2a2 are provided with clearance holes 2a4, which extend from the through holes 2a2 along the width direction of the guide groove 2a1 toward the limiting card slot 2a3.

[0068] In this embodiment, the marking structure 30 includes scale lines and scale values ​​and is arranged on one side of the guide slot 2a1 in the width direction, away from the other guide slot 2a1 arranged symmetrically along the imaginary line. The scale lines and scale values ​​are arranged one-to-one, and are also arranged one-to-one with the limit slot 2a3.

[0069] Taking this embodiment as an example, when in use, the fixation between the baffle 3 and the outer edge plate 12 is released by loosening the fixing parts, and according to the size of the photovoltaic silicon component, the baffle 3 is moved along the length direction of the guide groove 2a1 until the inner wall of the baffle 3 is flush with the corresponding scale line, and then the baffle 3 is moved along the width direction of the guide groove 2a1 to enter the corresponding limit slot 2a3, and the fixing parts are tightened to fix the relative position between the baffle 3 and the outer edge plate 12, so that the size of the accommodating space is adapted to the size of the photovoltaic silicon component.

[0070] Example 3

[0071] See Figure 3 and Figure 4 , this embodiment provides a photovoltaic silicon wafer material box, which, like embodiment 1, can also be visually adjusted in size. The structure of the photovoltaic silicon wafer material box in this embodiment is similar to that of the photovoltaic silicon wafer material box in embodiment 1, with the difference that the adjustment unit 2b includes a mounting hole (unnumbered), a first magnetic body 2b2 disposed in the mounting hole, and a second magnetic body 2b3 magnetically fixed to the first magnetic body 2b2, and the second magnetic body 2b3 is fixed to the bottom of the baffle 3. The corner has two sides connected vertically, the length direction of the mounting hole is perpendicular to one side of the corresponding corner, and the length directions of the two mounting holes symmetrically arranged along the virtual line are perpendicular. In the length direction of the mounting hole, a socket 2b4 for the baffle 3 to pass through is arranged one-to-one on the first magnetic body 2b2 in the fixed position, the cross-sectional shape of the socket 2b4 is adapted to the cross-sectional shape of the baffle 3, and the cross-sectional area of ​​the second magnetic body 2b3 is larger than the cross-sectional area of ​​the socket 2b4.

[0072] In this embodiment, in the height direction, the top surface of the first magnetic body 2b2 is higher than the top surface of the outer edge plate 12, the bottom surface of the first magnetic body 2b2 is higher than the bottom surface of the outer edge plate 12, and the distance between the bottom surface of the first magnetic body 2b2 and the bottom surface of the outer edge plate 12 is equal to the thickness of the second magnetic body 2b3. The second magnetic body 2b3 is fixed to the bottom of the baffle 3 by a double countersunk screw 2b5. When the baffle 3 is fixed to the outer edge plate 12 through the second magnetic body 2b3 and the first magnetic body 2b2, the bottom surface of the second magnetic body 2b3 is flush with the bottom surface of the outer edge plate 12 to ensure the placement stability of the photovoltaic silicon wafer box. Specifically, the first magnetic body 2b2 is made of iron, and the second magnetic body 2b3 is made of a strong magnet. This is a conventional setting.

[0073] In this embodiment, the marking structure 30 is a scale value, and the scale value is arranged on the side of the mounting hole in the width direction, away from the other mounting hole arranged symmetrically along the virtual line. The scale value is set one-to-one with the socket 2b4. It should be noted that the length direction of the mounting hole is as follows: Figure 3 As shown by arrow c, the width direction of the mounting hole is as follows Figure 3 As shown by the arrow d in the middle, the height direction is Figure 3 As shown by arrow e.

[0074] Taking this embodiment as an example, when in use, according to the size of the photovoltaic silicon component, the top end of the baffle 3 is passed from bottom to top in the corresponding socket 2b4. Since the cross-sectional area of ​​the second magnetic body 2b3 is larger than the cross-sectional area of ​​the socket 2b4, the baffle 3 is restricted from continuing to pass through the socket 2b4. At this time, the first magnetic body 2b2 and the second magnetic body 2b3 are attracted to fix the relative position between the baffle 3 and the outer edge plate 12, so that the size of the accommodating space is adapted to the size of the photovoltaic silicon component.

[0075] Example 4

[0076] See Figures 5 to 7 . The present embodiment provides a photovoltaic silicon wafer material box, which, like the embodiment 1, can also be visually adjusted in size. The structure of the photovoltaic silicon wafer material box in the present embodiment is similar to that of the photovoltaic silicon wafer material box in the embodiment 1, with the difference that: the positioning structure 2c includes a guide groove 2c1, a guide slider 2c2 slidably connected to the guide groove 2c1, and a locking member (not shown) for locking the relative position of the guide groove 2c1 and the guide slider 2c2. The axis of the guide groove 2c1 in the length direction is collinear with the virtual line, and the stop structure includes two baffles 3. The two baffles 3 are provided on the guide slider 2c2 and are symmetrically arranged along the virtual line and perpendicular to each other. The identification structure 30 is arranged on at least one side of the guide groove 2c1 in the width direction.

[0077] It should be noted that the length direction of the guide groove 2c1 is as follows: Figure 6 As shown by the arrow f in the middle, the width direction of the guide groove 2c1 is as follows Figure 6 As shown by arrow g in the middle.

[0078] Specifically, guide slot 2c1 is provided with guide holes 2c3 on both sides of the width direction. The guide holes 2c3 extend along the length of the guide slot 2c1. The locking member passes through the guide holes 2c3 to secure the guide slider 2c2. In this embodiment, the locking member is a bolt. The head end of the bolt is located below the outer edge plate 12, and the tail end passes through the guide holes 2c3 to be threadedly connected to the bottom of the guide slider 2c2.

[0079] In this embodiment, the guide slider 2c2 has an L-shaped cross-section. The guide slider 2c2 includes an opposing concave surface 2c21 and a convex surface 2c22, as well as two side planes 2c23 connecting the concave and convex surfaces 2c21 and 2c22. The concave surface 2c21 of the guide slider 2c2 faces the hollowed-out area 11. Two baffles 3 are integrally formed at either end of the concave surface 2c21 of the guide slider 2c2, with the sidewalls of the two baffles 3 flush with the two side planes 2c23. In the height direction, the orthographic projections of the baffles 3 partially overlap with the orthographic projection of the guide slider 2c2.

[0080] In this embodiment, the marking structure 30 includes scale lines and scale values. The marking structures 30 corresponding to the four groups of adjustment structures are symmetrically arranged on opposite sides of the outer edge plate 12.

[0081] To facilitate alignment of the inner sidewall of the baffle 3 with the scale line, thereby improving adjustment accuracy, in this embodiment, a pointer 6 is provided at each end of the guide slider 2c2. Specifically, the pointer 6 is integrally formed with the guide slider 2c2 and includes an inner wall 61, an outer wall 62, a top wall (not numbered), and a bottom wall (not numbered). The inner wall 61 of the pointer 6 extends from the inner sidewall of the baffle 3 along the width of the baffle 3 toward the sidewall of the guide groove 2c1. The outer wall 62 of the pointer 6 extends from the side plane 2c23 of the guide slider 2c2 along the length of the guide groove 2c1 toward the hollow area 11 and connects with the inner wall 61 of the pointer 6, forming a tip of the pointer 6, which is used to point to the scale line. To prevent the pointer 6 from contacting the photovoltaic silicon wafer and causing damage to the photovoltaic silicon wafer, in this embodiment, the bottom surface of the pointer 6 is flush with the bottom surface of the guide slider 2c2, and the thickness of the pointer 6 is less than the groove depth of the guide groove 2c1.

[0082] Taking this embodiment as an example, when in use, the locking piece is loosened to release the fixation between the guide sliding block 2c2 and the guide sliding groove 2c1, and according to the size of the photovoltaic silicon component, the baffle 3 is moved along the length direction of the guide sliding groove 2c1 until the inner wall 61 of the pointer 6 is flush with the corresponding scale line, and then the locking piece is tightened to fix the relative position between the guide sliding block 2c2 and the guide sliding groove 2c1, so that the size of the accommodating space is adapted to the size of the photovoltaic silicon component.
