Description

Technical Field

[0001] This utility model belongs to the field of quartz wafer technology, specifically, it relates to an adjustable quartz wafer positioning fixture. Background Technology

[0002] Quartz is the most widely distributed mineral in the quartz group. Quartz comes in a variety of colors, from colorless and transparent to different shades of color. After processing, quartz can be made into various finished products, such as glass, ceramics, and optical fibers. The manufacturing process involves cutting, grinding, and punching.

[0003] A document with publication number (CN222290647U) discloses a positioning fixture for quartz processing, comprising a positioning base and a positioning shell. The fixture is characterized by: the top of the positioning shell being fixedly connected to the bottom of the positioning base; device plates being fixedly connected to both sides of the positioning base; a rotary motor being installed on one side of each of the two device plates; and two positioning devices being installed on the top of the positioning base. By using the positioning devices, positioning plates, anti-slip pads, moving rods, and rotary motors in combination, the fixture solves the problem of requiring cutting, grinding, and punching equipment during quartz processing. The fixture is an auxiliary tool for positioning and processing; the material to be processed is placed on the fixture, and then the position of the positioning plate is adjusted using bolts to limit the movement of the material.

[0004] Existing clamping devices have significant technical defects in the process of clamping and processing quartz wafers. The clamping and quartz wafers are in rigid contact, and this rigid clamping mechanism cannot effectively buffer and absorb mechanical vibrations during processing. Due to the high brittleness and low mechanical strength of quartz wafers, under the combined effects of continuous vibration and rigid clamping, microcracks or even breakage can easily occur on the wafer surface, resulting in a significant reduction in product qualification rate.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the technical problem of limiting the position during quartz wafer processing, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An adjustable quartz wafer positioning fixture includes a base, an operating table fixedly connected to the base, a processing table fixedly connected to the center of the operating table, and a fixing block fixedly connected to the side of the operating table; and a clamping assembly symmetrically arranged on the base and the operating table. The clamping assembly is used to limit the positioning of the quartz wafer. The clamping assembly includes a mounting frame, clamping blocks, push rods, and connecting blocks. The mounting frames are symmetrically arranged on the operating table, and each mounting frame is movably connected to the base. The clamping blocks are arranged in an array on the mounting frames, and each clamping block is elastically connected to a corresponding mounting frame. The corresponding mounting frame is fixedly connected to the connecting block, the connecting block is slidably connected to the operating table, and each connecting block is drivenly connected to a corresponding push rod. The inner wall of each clamping block is arc-shaped, and the corners of adjacent clamping blocks are chamfered.

[0008] In a preferred embodiment of the present invention, the base is symmetrically provided with mounting frames in the middle, and each mounting frame is fixedly connected to the base. Each mounting frame is slidably connected with a movable block, and the push rod is fixedly connected to the end of each movable block. The fixed block and the push rod are connected by a pin.

[0009] In a preferred embodiment of this utility model, each of the mounting frames is provided with a transmission block, and the corresponding transmission block is slidably connected to the mounting frame, the corresponding connecting block is fixedly connected to the transmission block, and the corresponding transmission block is elastically connected to the movable block.

[0010] In a preferred embodiment of the present invention, each movable block is fixedly connected with a plurality of first abutting blocks, each first abutting block abuts against a second abutting block, and the second abutting block is fixedly connected to the corresponding transmission block.

[0011] In a preferred embodiment of this utility model, a movable rod is provided between each movable block and the transmission block, the end of each movable rod is fixedly connected to the corresponding transmission block, and each movable rod is elastically connected to the corresponding movable block.

[0012] In a preferred embodiment of this utility model, each movable block is provided with a trapezoidal hole, each movable rod is movably connected to the corresponding trapezoidal hole, and a second spring is fixedly connected to each movable rod, with the corresponding second spring abutting against the trapezoidal groove.

[0013] In a preferred embodiment of this utility model, a plurality of connecting rods are slidably connected inside the mounting frame, and the corresponding clamping blocks are fixedly connected to the connecting rods and slidably connected to the mounting frame.

[0014] In a preferred embodiment of the present invention, each connecting rod is fitted with a first spring, and the end of each first spring is fixedly connected to the corresponding mounting bracket and clamping block. Each clamping block is symmetrically provided with sponges, and the corresponding sponges are fixedly connected to the clamping blocks.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This adjustable quartz wafer positioning fixture uses elastically set clamping blocks to clamp and limit quartz wafers of different specifications. Due to the elastic setting and flexible clamping of the clamping blocks, the edges of the quartz wafers are elastically clamped, avoiding the inability to effectively buffer and absorb mechanical vibrations caused by rigid contact during the processing of quartz wafers, thereby improving the yield of quartz wafers.

[0017] 2. This adjustable quartz wafer positioning fixture comprises a push rod, a movable block, a first abutment block, a second abutment block, a transmission block, and other components. When these components are assembled, the transmission block drives the connecting block to move, and the connecting block drives the mounting frame and the clamping block to move. The clamping block is driven to make close contact with the edge of the quartz wafer, thereby restricting the position of the quartz wafer and pushing it to the center of the processing table. This uniformly restricts the processing position of quartz wafers in the same batch and controls the processing quality of the quartz wafers.

[0018] 3. This adjustable quartz wafer positioning fixture completes the clamping and limiting of the quartz wafer by pushing a push rod, quickly completing the clamping and limiting steps, reducing operation steps, and improving processing efficiency.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Please see Figure 1-5 An adjustable quartz wafer positioning fixture includes a base 1, an operating table 11 fixedly connected to the base 1, a processing table 12 fixedly connected to the center of the operating table 11, and a fixing block 13 fixedly connected to the side of the operating table 11; and a clamping assembly symmetrically arranged on the base 1 and the operating table 11. The clamping assembly is used to limit the positioning of the quartz wafer. The clamping assembly includes a mounting frame 2, clamping blocks 21, a push rod 3, and a connecting block 4. The mounting frames 2 are symmetrically arranged on the operating table 11, and each mounting frame 2 is movably connected to the base 1. The clamping blocks 21 are arrayed on the mounting frames 2, and each clamping block 21 is elastically connected to the corresponding mounting frame 2. The corresponding mounting frame 2 is fixed to the connecting block 4. The connecting block 4 is slidably connected to the operating table 11. Each connecting block 4 is connected to the corresponding push rod 3. The inner wall of each clamping block 21 is arc-shaped, and the corners of adjacent clamping blocks 21 are chamfered. The quartz wafer is placed on the processing table 12, and the push rod 3 is pushed inward manually. The push rod 3 drives the mounting frame 2 after cooperating with the structure inside the clamping assembly. The mounting frame 2 drives the clamping block 21. The clamping block 21 is in close contact with the edge of the quartz wafer. Due to the elastic setting of the clamping block 21, the edge of the quartz wafer is elastically clamped. In the processing of quartz wafers, the rigid contact method is avoided, which cannot effectively buffer and absorb mechanical vibration, thus improving the pass rate of quartz wafers.

[0029] The base 1 has symmetrically arranged mounting frames 31 in the middle, and each mounting frame 31 is fixedly connected to the base 1. Each mounting frame 31 has a movable block 32 slidably connected to it. A push rod 3 is fixedly connected to the end of each movable block 32. A fixed block 13 is connected to the push rod 3 via a pin. When the push rod 3 is manually pushed inward, it moves the movable block 32. After the push rod 3 is pushed to the appropriate position, it is engaged and limited by the pin with the fixed block 13, fixing its position. After processing, the pin is removed, and the push rod 3 is pushed outward due to the components within the clamping assembly, completing the rapid loading and unloading of the quartz wafer. Since the pin is existing technology and is publicly known, it is not described in detail in this text. Figure 1 As can be seen from the text, I will not repeat it here.

[0030] Each mounting frame 31 is equipped with a transmission block 41, and the corresponding transmission block 41 is slidably connected to the mounting frame 31. The corresponding connecting block 4 is fixedly connected to the transmission block 41, and the corresponding transmission block 41 is elastically connected to the movable block 32. Each movable block 32 is fixedly connected with multiple first abutting blocks 33, and each first abutting block 33 abuts against a second abutting block 34. The second abutting block 34 is fixedly connected to the corresponding transmission block 41. When the push rod 3 moves, it drives the movable block 32. When the movable block 32 moves, it drives the first abutting blocks 33. When the first abutting blocks 33 move, they move laterally. The second abutment block 34 is pushed, which in turn pushes the transmission block 41 longitudinally. The transmission block 41 drives the connecting block 4 to move, and the connecting block 4 drives the mounting frame 2 and the clamping block 21 to move. The clamping block 21 is driven to make close contact with the edge of the quartz wafer, thus restricting the position of the quartz wafer and pushing it to the middle of the processing table 12. This uniformly restricts the processing position of quartz wafers in the same batch and controls the processing quality of the quartz wafers. The clamping and limiting of the quartz wafer is completed by pushing the push rod 3, which quickly completes the clamping and limiting steps, reduces the number of operation steps, and improves processing efficiency.

[0031] Each movable block 32 is connected to a transmission block 41 by a movable rod 42. The end of each movable rod 42 is fixedly connected to the corresponding transmission block 41, and each movable rod 42 is elastically connected to the corresponding movable block 32. Each movable block 32 has a trapezoidal hole, and each movable rod 42 is movably connected to the corresponding trapezoidal hole. A second spring 43 is fixedly connected to each movable rod 42, and the corresponding second spring 43 abuts against the trapezoidal groove. The transmission block 41 moves, driving the movable rod 42. The movable rod 42 compresses the second spring 43, causing the second spring 43 to deform and apply the deformation force to the movable rod 42. After the push rod 3 separates from the pin between it and the fixed block 13, the push rod 3 loses its restraining force. The movable rod 42 pushes the transmission block 41, the transmission block 41 pushes the second abutment block 34, the second abutment block 34 pushes the first abutment block 33, the first abutment block 33 pushes the movable block 32, and the movable block 32 pushes the push rod 3, quickly completing the clamping and release of the quartz wafer, making it easy to remove the quartz wafer.

[0032] The mounting frame 2 has multiple connecting rods 22 slidably connected inside, and corresponding clamping blocks 21 are fixedly connected to the connecting rods 22 and slidably connected to the mounting frame 2. Each connecting rod 22 is fitted with a first spring 23, and the end of each first spring 23 is fixedly connected to the corresponding mounting frame 2 and clamping block 21. Each clamping block 21 is symmetrically provided with a sponge 24, and the corresponding sponge 24 is fixedly connected to the clamping block 21. After the edge of the quartz wafer contacts the clamping block 21, the quartz wafer is clamped between the clamping blocks 21. The edge of the quartz wafer contacts the sponge 24. Through the pressure deformation buffering characteristics of the sponge 24, the edge of the quartz wafer is protected. For protection, the clamping block 21 moves and pushes the connecting rod 22, which compresses the first spring 23. The first spring 23 deforms and applies the force of the deformation to the connecting rod 22. The connecting rod 22 pushes the clamping block 21, which is pushed to make close contact with the edge of the quartz wafer, thus ensuring a tight fit. The elastically set clamping block 21 can clamp and limit quartz wafers of different specifications. Due to the elastic setting and flexible clamping of the clamping block 21, the edge of the quartz wafer is elastically clamped. In the processing of quartz wafers, rigid contact is avoided, which would prevent effective buffering and absorption of mechanical vibration, thereby improving the yield rate of quartz wafers.

[0033] Working principle: A quartz wafer is placed on the processing table 12. The push rod 3 is manually pushed inwards. The push rod 3, through the interaction of the clamping assembly's internal structure, drives the mounting frame 2. The mounting frame 2 drives the clamping block 21, which makes close contact with the edge of the quartz wafer. Due to the elastic setting of the clamping block 21, the quartz wafer is elastically clamped, avoiding the inability to effectively buffer and absorb mechanical vibrations caused by rigid contact during processing, thus improving the yield rate of the quartz wafer. The push rod 3 is manually pushed inwards, causing the movable block 32 to move. After the push rod 3 is pushed to the appropriate position, it is engaged and limited by a pin with the fixed block 13, fixing the position of the push rod 3. After processing, the pin is removed, and the push rod 3 is pushed outwards by the components within the clamping assembly, completing the rapid loading and unloading of the quartz wafer. Since the pin is existing and publicly known technology, it is not described in detail in this article. Figure 1As can be seen and will not be elaborated further, the push rod 3 moves, driving the movable block 32, which in turn drives the first abutting block 33. The first abutting block 33, in its movement, pushes the second abutting block 34 laterally, which in turn pushes the transmission block 41 longitudinally. The transmission block 41 drives the connecting block 4 to move, which in turn drives the mounting bracket 2 and the clamping block 21 to move. The clamping block 21 is thus brought into close contact with the edge of the quartz wafer, restricting its position and pushing it to the center of the processing table 12 for processing the same batch of quartz wafers. The device provides uniform constraints to control the processing quality of quartz wafers. The clamping and limiting of the quartz wafers is achieved by pushing the push rod 3, quickly completing the clamping and limiting steps, reducing operation steps, and improving processing efficiency. During movement, the transmission block 41 drives the movable rod 42, which compresses the second spring 43. The second spring 43 deforms and applies the deformation force to the movable rod 42. After the push rod 3 separates from the fixed block 13, the push rod 3 loses its limiting force, and the movable rod 42 pushes the transmission block 41, which in turn pushes the second abutment block 34. The second abutment block 34 pushes the first abutment block 33, the first abutment block 33 pushes the movable block 32, and the movable block 32 pushes the push rod 3, quickly completing the clamping and releasing of the quartz wafer, making it easy to remove the quartz wafer. After the edge of the quartz wafer contacts the clamping block 21, the quartz wafer is stuck between the clamping blocks 21. The edge of the quartz wafer contacts the sponge 24. Through the pressure deformation buffering characteristics of the sponge 24, the edge of the quartz wafer is protected. As the clamping block 21 moves, it pushes the connecting rod 22. The connecting rod 22 compresses the first spring 23. 23 deforms and applies the deformation force to the connecting rod 22. The connecting rod 22 pushes the clamping block 21, which is pushed to make close contact with the edge of the quartz wafer, thus tightly fitting the edge of the quartz wafer. The clamping block 21, which is elastically set, clamps and limits quartz wafers of different specifications. Due to the elastic setting and flexible clamping of the clamping block 21, the edge of the quartz wafer is elastically clamped. In the processing of quartz wafers, the rigid contact method is avoided, which cannot effectively buffer and absorb mechanical vibration, thereby improving the yield of quartz wafers.
