Description

Technical Field

[0001] This utility model relates to the field of crystal rod bonding technology, specifically a silicon carbide wire-cut spacer bonding tool. Background Technology

[0002] The traditional cutting and bonding technique involves splicing silicon carbide crystal rods together with paraffin wax, and then bonding them to the material holder with epoxy resin to fix the crystal rods on the material holder.

[0003] Traditional bonding techniques have the following problems: 1. As the thickness of the crystal rod splicing increases, the difficulty of sticking the rods increases and the curing time is prolonged. If the single rod stick is used, on the one hand, the bonding accuracy cannot be guaranteed, and on the other hand, due to the mutual influence of the bonding process, the curing time will increase exponentially. 2. During the cutting process, as the thickness of the crystal rod increases, the edges of the crystal rod are prone to chipping and cracking, causing the crystal rod to be scrapped; 3. During the cutting process, due to the thickness of the crystal rod, there is a difference in the cutting progress between the middle and the two sides, and there may be a situation where the middle area cannot be cut through. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a silicon carbide wire-cut interval stick bonding fixture, which can solve the problem of increased stick bonding difficulty due to increased crystal rod thickness, and improve the crystal rod yield while shortening the crystal rod curing time and improving bonding accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A silicon carbide wire-cut spacer bonding fixture includes a bonding block and a spacer positioning device. The bonding block defines a receiving space for accommodating the crystal rods to be bonded. The center of the receiving space does not coincide with the center of the bonding block and is located below the center of the bonding block. The spacer positioning device is used to position the bonding block.

[0006] Preferably, the receiving space is a circular structure, and its inner diameter is adapted to the outer diameter of the crystal rod to be bonded, so as to ensure that the crystal rod to be bonded can be placed in the receiving space.

[0007] Preferably, the center of the receiving space is located at one-third of the distance from the bottom end of the splicing rod positioning block, which ensures that after the crystal rod to be bonded is placed in the receiving space, its bonding position is located outside the splicing rod positioning block, which facilitates the bonding of the crystal rod to be bonded to the resin strip.

[0008] Preferably, positioning holes I are provided at all four corners of the splicing rod positioning block.

[0009] Preferably, the interval positioning device includes a positioning seat, a positioning plate, and a positioning rod. The positioning seat is used to support and fix the positioning plates on the front and rear sides. The positioning plate on the front side is fixedly set at one end of the positioning seat, and the positioning plate on the rear side is set at the other end of the positioning seat according to the number of positioning blocks required. The four corners of the positioning plate are respectively provided with positioning holes II that match the positioning rod. The positioning rod is connected to the positioning plates on the front and rear sides through the positioning holes II.

[0010] Preferably, the positioning blocks of the splicing rods pass through the positioning holes I on them sequentially on the positioning rods, and the distance between adjacent positioning blocks is equal.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features at least one splicing rod positioning block, which is a plate with a circular groove. This groove defines a space for accommodating the crystal rod to be bonded. The inner diameter of this space matches the outer diameter of the crystal rod, ensuring that the crystal rod can be positioned precisely within it. Furthermore, the center of this invention is not aligned with the center of the splicing rod positioning block; instead, the center of the space is positioned below the center of the positioning block. This ensures that after the crystal rod is placed in the space, its bonding position is outside the positioning block, facilitating bonding between the crystal rod and the resin strip. In this invention, the crystal rods to be bonded are sequentially placed in the receiving space of the splicing rod positioning block. The number of splicing rod positioning blocks can be set according to the number of crystal rods to be bonded. The bonding position of the crystal rods to be bonded is set downward facing the resin strip on the positioning seat, so as to facilitate bonding the crystal rods to be bonded to the resin strip. The spacing positioning device of this utility model is used to position the splicing rod positioning blocks; the positioning seat is used to support and fix the front and rear positioning plates, wherein the front positioning plate is fixedly set at one end of the positioning seat, and the rear positioning plate is set at the other end along the positioning seat according to the number of splicing rod positioning blocks required; positioning holes are opened on the four corners of the positioning plate, and the positioning rod is connected to the front and rear positioning plates through the positioning holes; the splicing rod positioning blocks are sequentially inserted through the positioning holes on them onto the positioning rod, the distance between adjacent positioning plates is equal, and the splicing rod positioning blocks fixed by the positioning rod are all in a horizontal state and are all perpendicular to the bottom positioning seat. Then, the resin strip coated with stick adhesive is placed on the positioning seat to bond and fix it to the crystal rod to be bonded; after curing, the crystal rod and the splicing rod positioning blocks are separated, and this operation is completed.

[0012] This invention can solve the problem of increased sticking difficulty caused by increased crystal rod thickness, and improve the yield of crystal rods while shortening the crystal rod curing time and improving the bonding accuracy. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] A silicon carbide wire-cut spacer sticking fixture includes a stick positioning block 1 and a spacer positioning device, such as... Figure 1 As shown, the piecing block positioning block 1 defines the accommodating space 11, as follows: Figure 2 As shown, the accommodating space 11 is used to accommodate the crystal rod 2 to be bonded; as Figure 3 As shown, the interval positioning device is used to position the splicing bar positioning block 1.

[0017] In this embodiment, as Figure 1 As shown, the accommodating space 11 has a circular structure, and its inner diameter is adapted to the outer diameter of the crystal rod 2 to be bonded, which can ensure that the crystal rod 2 to be bonded can be placed in the accommodating space 11.

[0018] In this embodiment, as Figure 1 and Figure 2 As shown, the center of the receiving space 11 does not coincide with the center of the splicing rod positioning block 1 and is located below the center of the splicing rod positioning block 1. This ensures that after the crystal rod 2 to be bonded is placed in the receiving space 11, its bonding position is located outside the splicing rod positioning block 1, facilitating the bonding of the crystal rod 2 to be bonded to the resin strip 3. In this embodiment, the center of the receiving space 11 and the center of the splicing rod positioning block 1 can be set on the same central axis.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, in order to facilitate processing, the center of the accommodating space 11 is set at a position 1 / 3 above the bottom end of the splicing rod positioning block 1.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, in order to facilitate fixing the splicing rod positioning block on the interval positioning device, the present invention provides positioning holes I41 at the four corners of the splicing rod positioning block 1.

[0021] In this embodiment, as Figure 3 and Figure 4 As shown, the interval positioning device includes a positioning seat 5, a positioning plate 6, and a positioning rod 7. The positioning seat 5 is used to support and fix the front and rear positioning plates 6. The front positioning plate 6 is fixedly set at one end of the positioning seat 5, and the rear positioning plate 6 is set at the other end along the positioning seat 5 according to the number requirements of the splicing rod positioning blocks 1. The four corners of the positioning plate 6 are respectively provided with positioning holes II 42 that match the positioning rod 7. The positioning rod 7 is connected to the front and rear positioning plates 6 through the positioning holes II 42.

[0022] In this embodiment, as Figure 3 and Figure 4 As shown, the positioning blocks 1 are sequentially inserted into the positioning rods 7 through the positioning holes I41 on them, and the distance between adjacent positioning blocks 1 is equal.

[0023] Working principle: This utility model incorporates at least one splicing rod positioning block 1, the number of which can be selected based on the number of crystal rods 2 to be bonded; for example... Figure 1 and Figure 2 As shown, the splicing rod positioning block 1 of this utility model is a plate with a circular groove, which defines the space for accommodating the crystal rods to be bonded. The width of the splicing rod positioning block 1 and the size of the accommodating space can be customized according to the number and size of the crystal rods 2 to be bonded. For example, if there are 9 crystal rods with a thickness of 10mm and a splicing rod thickness of 90mm, they are divided into 3 groups, with 3 crystal rods 2 to be bonded in each group and each group having a length of 30mm. Then, they are bonded to the resin strip 3 in sections. In this utility model, the width of the accommodating space 11 can be set to 30mm, and the 3 crystal rods 2 to be bonded are placed in the accommodating space of the splicing rod positioning block 1 in sequence, with the bonding positions of the 3 crystal rods 2 facing downwards towards the resin strip 3 on the positioning seat 5. In this embodiment, the width of the accommodating space 11 of the splicing rod positioning block 1 can be set according to the actual situation.

[0024] The inner diameter of the accommodating space of this utility model is exactly matched with the outer diameter of the crystal rod 2 to be bonded. The size of the accommodating space can be set according to the diameter of the crystal rod 2 to be bonded. This utility model does not make any other explanation of the accommodating space, so that the crystal rod 2 to be bonded can be set in the accommodating space. In addition, this utility model sets the center of the accommodating space to be different from the center of the splicing rod positioning block 1. The center of the accommodating space is set below the center of the splicing rod positioning block 1. This is to ensure that after the crystal rod 2 to be bonded is set in the accommodating space, its bonding position is located on the outer side of the bottom end of the splicing rod positioning block 1, so as to facilitate the bonding of the crystal rod 2 to be bonded to the resin strip 3. The spacing positioning device of this utility model is used to position the splicing rod positioning block; the positioning seat 5 is used to support and fix the front and rear positioning plates 6, wherein the front positioning plate 6 is fixedly set at the front end of the positioning seat 5, and the rear positioning plate 6 is set at the rear end along the positioning seat 5 according to the number of splicing rod positioning blocks required; in this embodiment, the positioning plate 6 can be fixed on the positioning seat 5 by plugging. For example, if the front and rear ends of the positioning seat 5 are provided with positioning grooves that are compatible with the bottom of the positioning plate 6, the positioning plate 6 can be directly inserted into the positioning groove of the positioning seat 5, thereby fixing the positioning plate 6. Positioning holes II 42 are provided on all four corners of the positioning plate 6. The positioning rod 7 is connected to the positioning plates 6 on the front and rear sides through the positioning holes II 42. The splicing rod positioning blocks 1 are inserted through the positioning holes I 41 on them and are inserted through the positioning rod 7. The distance between adjacent splicing rod positioning blocks 1 is equal. After being fixed by the positioning rod 7, the splicing rod positioning blocks 1 are all in a horizontal state and are all perpendicular to the bottom positioning seat 5. Then, the resin strip 3 with adhesive stick is placed on the positioning seat 5 to bond and fix it to the crystal rod 2 to be bonded. After curing, the crystal rod and the splicing rod positioning blocks 1 are separated. This operation is completed.

[0025] This invention can solve the problem of increased sticking difficulty caused by increased crystal rod thickness, and improve the yield of crystal rods while shortening the crystal rod curing time and improving the bonding accuracy.
