[0002] In the semiconductor field, some large-area thin-plate products will bend and deform when placed horizontally due to their own material and weight. Such bending and deformation will have an irreversible impact on product quality, seriously affecting product yield and output. At the same time, in some specific processes (especially processes under high temperature conditions, such as high-temperature baking, etc.), it is necessary to ensure that such thin plates are placed vertically to avoid bending and deformation during the process production, which will affect product quality. At present, there is no clamping fixture that can effectively clamp such thin-plate products and can be used for vertical storage and placement of products, as well as vertical process production.

DETAILED DESCRIPTION

[0026] A fixture for thin plate products, see Figure 1-Figure 4 , which includes a positioning frame assembly 10, a pair of mounting devices 20, a pair of handles 30; and a plurality of elastic clamping devices 40.

[0027] In a specific embodiment, the positioning frame assembly 10 includes two transverse frames and two longitudinal frames 11, the two longitudinal frames are an upper frame 12 and a lower frame 13, and the two transverse frames and the two longitudinal frames 11 are fixed end to end to form a rectangular frame structure;

[0028] Four sets of elastic clamping devices 40 are arranged in the length direction of the upper frame 12 and the lower frame 13, respectively. The elastic clamping devices 40 on the upper frame 12 and the lower frame 13 clamp the corresponding positions of the corresponding edges of the thin plate product 50, and the middle of the length direction of the longitudinal frames 11 on both sides are respectively provided with raised handles 30, which are used for people to carry the clamp;

[0029] A pair of mounting devices 20 are disposed on both sides of the upper frame 12 and are disposed in a side convex manner;

[0030] Each set of elastic clamping devices 40 uses elasticity to clamp the corresponding edge of the thin plate product 50;

[0031] A plurality of elastic clamping devices 40 are arranged in the length direction of the upper frame 12 and the lower frame 13. The elastic clamping devices 40 on the upper frame 12 and the lower frame 13 clamp the corresponding positions of the corresponding edges of the thin plate product 50 respectively, and raised handles 30 are respectively provided in the middle of the length direction of the longitudinal frames 11 on both sides.

[0032] In specific implementation: side convex mounting devices 20 are respectively fixed on both sides of the length direction of the upper frame 12, and each set of mounting devices is used to place the fixture on the storage rack or fix it inside the process chamber;

[0033] The mounting device 20 is a circular roller, a column, or a convex shape such as a square, a trapezoid, or a triangle. The mounting device 20 is fixed to the corresponding end of the upper frame 12 by bolts, which allows the corresponding shape structure of the mounting device to be quickly adjusted according to the actual mounting position;

[0034] The positioning frame assembly 10 is formed by four sets of frames fixed together by fasteners, which enables the positioning frame assembly 10 to be quickly assembled according to the shape of the product, making the entire fixture highly versatile.

[0035] In a specific embodiment, each group of elastic clamping devices 40 includes an upper pressure block 41, a lower cushion block 42, a guide column 43, a linear spring 44, a manual knob 45, and a guide bushing 46. A guide column through hole 101 and a lower cushion block mounting hole 102 are provided at the position where the elastic clamping device 40 needs to be installed on the corresponding frame. The guide column 46 penetrates the guide column through hole 101 from bottom to top and convexes upward. The guide bushing 46 includes an outer convex guide ring 461 and a lower convex guide sleeve 462. The lower convex guide sleeve 462 of the guide bushing 46 is sleeved on the guide column 43 and then inserted into the guide column through hole 101. The outer wall of the lower convex guide sleeve 462 is arranged in close contact with the inner wall of the guide column through hole 101. The outer convex guide ring 461 is pressed onto the upper surface of the frame. The bottom of the guide column 43 is sleeved with a spring baffle 47. The bottom of the lower convex guide sleeve 462 A linear spring 44 is arranged between the lower part and the spring stopper 47. The linear spring 44 is sleeved on the corresponding bottom periphery of the guide column 43. The outer end of the lower pad 42 is fixed to the lower pad mounting hole 102 by a fastening bolt. The inner end of the lower pad 42 is convex to the inner edge of the frame. The inner end of the manual knob 45 in the length direction is fixed with an upper pressing block 41. The middle part of the manual knob 45 in the length direction is fixed to the upper convex end of the guide column 46 by a connecting bolt 48. In the unclamped state, the upper pressing block is pressed on the upper surface of the corresponding frame. In the clamped state, the manual knob 45 rotates toward the lower pad 42. The lower part of the corresponding edge of the thin plate product 50 is supported on the upper surface of the lower pad 42. The bottom of the upper pressing block 41 is pressed on the upper part of the corresponding edge of the thin plate product 50, and the upper pressing block 41 is arranged directly above the lower pad 42.

[0036] Thick feet 60 are fixed on the back of the four corners of the rectangular frame structure. When personnel take and place thin plate products on the fixture, the fixture is lifted up at a certain safe distance above the work surface so that the product does not touch the excess work surface during the taking and placing process, thereby reducing the risk of products contacting excess objects during the taking and placing process, causing scratches, marks, and dust particles on the products. When multiple fixtures are placed and fixed in batches, the feet 60 also play a role of equal spacing limit, preventing the fixtures from shaking and colliding during the process, thereby preventing the products from being damaged. At the same time, it also makes way for mechanisms such as the fixture's elastic clamping device 40.

[0037] In addition, the positioning frame assembly 10 is set according to the shape of the thin plate product 50, including a rectangle, a circle, an ellipse, and an irregular polygon.

[0038] Its working principle is as follows: the corresponding edges of thin plate products are clamped by an elastic clamping device so that the thin plate products can be reliably clamped. The elasticity of the elastic clamping device itself is used to clamp the product to prevent the product from shaking or falling off during transportation. Due to its elastic nature, it can be compatible with different product thicknesses within a specified range. The clamp is then placed on a storage rack or fixed inside a process chamber through a mounting device. This allows the clamp to manually clamp thin plate products effectively. After clamping, the product can be stored vertically. At the same time, the clamping fixture can be directly used for process production in the vertical direction under characteristic environments.
