Description

Technical Field

[0001] The utility model relates to the field of drying ceramic substrates, in particular to a clamp used for drying ceramic substrates. Background Art

[0002] Ceramic substrates need to undergo ultrasonic cleaning and drying processes before vacuum coating, sputtering or use. After cleaning and removing impurities and oxides on the ceramic substrates, the substrates need to be dried to remove residual moisture on the surface to ensure that the surface of the ceramic substrates is pure enough to prevent moisture from remaining on the substrate, which may cause bubbles during the sputtering process or affect the performance of the final product. Figure 4 It is a structural schematic diagram of a glass culture dish of the prior art, such as Figure 4 As shown, the conventional drying method is: placing the ceramic substrate in a glass culture dish, and then placing the culture dish containing the ceramic substrate into an oven.

[0003] However, in the drying process of this method, since one side of the ceramic substrate is in contact with the glass culture dish, water stains are easily left on the contact side, and the drying is insufficient, resulting in uneven drying of the ceramic substrate. In addition, during the transfer and operation process, the ceramic substrate has no limit and is easy to slide in the glass culture dish, and the surface of the substrate is easily damaged. It is impossible to ensure that the ceramic substrate has sufficient purity, which affects the quality and performance of the product. Utility Model Content

[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide a fixture for drying ceramic substrates, which facilitates the limitation of ceramic substrates through a fixing frame and a bottom plate, avoids damage to the ceramic substrates during movement, reduces the contact area between the ceramic substrates and the fixing frame, shortens the drying time, and ensures uniform drying.

[0005] The utility model adopts the following technical solutions:

[0006] A fixture for drying ceramic substrates comprises a base plate and a plurality of fixing frames, wherein the plurality of fixing frames are arranged on the base plate in parallel and at intervals, the base plate is provided with a plurality of placement grooves, the placement grooves are arranged in parallel and at intervals, and the placement grooves correspond to the fixing frames one by one, and the fixing frames are provided with embedding grooves, the embedding grooves are connected with the placement grooves so that the embedding grooves and the placement grooves enclose a clamping position for placing the ceramic substrate.

[0007] Furthermore, the fixing frame includes two oppositely arranged support plates, the support plates are perpendicular to the base plate, the embedding groove is opened on one side of the support plate, and the embedding grooves of the two support plates are arranged oppositely so that the embedding grooves of the two support plates and the placement groove form the clamping position.

[0008] Furthermore, one end of the embedding groove is connected to the placement groove, and the other end passes through the support plate, and the end of the embedding groove passing through the support plate forms an arc-shaped transition portion.

[0009] Furthermore, the clamping position includes a first clamping position and a second clamping position, the first clamping position and the second clamping position are arranged in parallel and spaced apart, and the distance between the embedding grooves on both sides of the first clamping position is different from the distance between the embedding grooves on both sides of the second clamping position.

[0010] Furthermore, the distance between the embedding grooves on both sides of the first clamping position is 48 mm±3 mm, and the distance between the embedding grooves on both sides of the second clamping groove is 60 mm±3 mm.

[0011] Furthermore, a handheld frame is included, and the handheld frame is arranged on one side of the base plate.

[0012] Furthermore, a hook hole is provided on the handheld frame.

[0013] Furthermore, the base plate and the handheld frame are an integrally formed structure.

[0014] Furthermore, the contact area between the ceramic substrate, the fixing frame and the bottom plate accounts for 10% of the total area of ​​the ceramic substrate.

[0015] Furthermore, the groove depth of the embedded groove is 8 mm±2 mm, and the groove width of the embedded groove is 3 mm±0.5 mm.

[0016] Furthermore, the fixing frame and the bottom plate are made of high temperature resistant polytetrafluoroethylene.

[0017] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are:

[0018] First, the ceramic substrate is limited by the clamping position surrounded by the embedding groove and the placement groove, so that the ceramic substrate is placed on the bottom plate. The contact area between the ceramic substrate and the fixing frame and the bottom plate is less than 10% when placed in the clamping position. Both sides can be dried at the same time, which reduces the drying time and makes the drying more uniform and thorough, thereby ensuring the purity of the ceramic substrate.

[0019] Second, through multiple clamping positions of different sizes, it is possible to dry ceramic substrates of different sizes at the same time. The fixing frames are arranged in parallel and spaced apart, so that the clamping positions are arranged in parallel and spaced apart, ensuring that multiple ceramic substrates do not contact each other when they are set on the clamping positions at the same time, ensuring uniform drying.

[0020] Third, the fixture can be moved by holding it with a hand-held stand, which is convenient for taking and transferring the fixture. The hand-held stand is provided with a hook hole, which can be hung on the oven or the wall through the hook for easy taking. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described below through specific implementation methods.

[0027] Reference Figures 1 to 3 The utility model is a fixture for drying ceramic substrates, comprising a bottom plate 1, a plurality of fixing frames 2 and a hand-held frame 3, wherein the plurality of fixing frames 2 are arranged in parallel and spaced apart on the bottom plate 1, the bottom plate 1 is provided with a plurality of placement grooves 10, the placement grooves 10 are arranged in parallel and spaced apart, and the placement grooves 10 correspond to the fixing frames 2 one by one, the fixing frames 2 are provided with an embedding groove 200, the embedding groove 200 is connected with the placement groove 200 so that the embedding groove 200 and the placement groove 10 enclose a clamping position 5 for placing a ceramic substrate 4. The hand-held frame 3 is arranged on one side of the bottom plate 1, the hand-held frame 3 is provided with a hook hole 30, and the bottom plate 1 and the hand-held frame 3 are an integrally formed structure.

[0028] The fixing frame 2 includes two supporting plates 20 arranged opposite to each other, the supporting plates 20 are perpendicular to the bottom plate 1, the embedding groove 200 is opened on one side of the supporting plate 20, and the embedding grooves 200 of the two supporting plates 20 are arranged opposite to each other, so that the embedding grooves 200 of the two supporting plates 20 and the placement groove 10 enclose the clamping position 5. The supporting plate 20 includes an embedding groove 200 and a supporting portion 201, and the embedding groove 200 is arranged on the supporting portion 201. The supporting portion 201 of each supporting plate 20 has different sizes, so that the distance between the two embedding grooves 200 arranged opposite to each other is different. A plurality of fixing frames 2 are arranged at intervals to form a plurality of first clamping positions and second clamping positions of different sizes. The distance between the embedding grooves on both sides of the first clamping position is 48 mm ± 3 mm, and the distance between the embedding grooves on both sides of the second clamping groove is 60 mm ± 3 mm. One end of the embedding groove 200 is connected to the placement groove 10, and the other end passes through the support plate 20. One end of the embedding groove 200 that passes through the support plate 20 forms an arc-shaped transition portion 202. The clamping position 5 is a groove with an open end surrounded by two oppositely arranged embedding grooves 200 and the placement groove 10 on the bottom plate 1.

[0029] The base plate 1, the fixing frame 2 and the hand-held frame 3 are made of high-temperature resistant polytetrafluoroethylene material. The depth of the embedding groove 200 is 8mm±2mm, the width of the embedding groove 200 is 3mm±0.5mm, and the size range of the ceramic substrate in daily use is 40×40×0.25mm to 60×49.5×1.5mm.

[0030] Continue to refer to Figures 1 to 3 When the utility model is used, according to the size of the ceramic substrate 4, a suitable clamping position 5 is selected, and the ceramic substrate 4 is inserted into the clamping position through the opening position above the clamping position 5. The ceramic substrate 4 is limited by the embedding groove 200 and the placement groove 10, and will not slide, thereby avoiding scratching the surface of the ceramic substrate 4. After the ceramic substrate 4 is placed, the fixture is placed in a drying furnace for drying. Since the contact area between the ceramic substrate 4 and the fixing frame 2 and the bottom plate 1 is reduced, and the front and back surfaces of the ceramic substrate 4 are exposed to the air, the two sides of the ceramic substrate 4 can be dried at the same time. The transition part 202 provided on the embedding groove 200 facilitates the insertion of the ceramic substrate 4 into the embedding groove 200, shortens the drying time, and can ensure uniform drying, effectively ensuring that the surface of the ceramic substrate 4 has sufficient purity, and the operation is simple and easy to use.
