Description

Technical Field

[0001] This invention relates to the field of crystal rod bonding technology, and in particular to a device and method for bonding crystal rods of different diameters. Background Technology

[0002] Crystal rod bonding equipment is commonly used in fields such as electronics, optoelectronics, and materials science to ensure the stability and reliability of crystal rods during processing or application.

[0003] Existing technologies, such as the invention with publication number CN116118021B, disclose an automatic crystal rod bonding device. This patent uses a transport device to convey the crystal rod to the bonding device; a crystal orientation measurement unit measures the crystal orientation of the crystal rod to obtain the X-axis deviation angle and X-axis deviation direction; a bonding communication control unit sends the X-axis crystal orientation deviation angle and X-axis crystal orientation deviation direction to a glue application communication control unit; a glue application unit adheres the lower surface of a buffer plate to the material holder with adhesive, and applies adhesive to the upper surface of the buffer plate to form a material holder assembly; wherein, the angle between the axis of the buffer plate and the axis of the material holder in a first direction is the X-axis crystal orientation deviation angle, and the first direction is opposite to the X-axis crystal orientation deviation direction; the upper surface of the buffer plate is an arc surface that is concave downward to match the side of the crystal rod; the transport device conveys the material holder assembly to the bonding device; the bonding unit rotates the axis of the material holder in the X-axis crystal orientation deviation direction by the X-axis crystal orientation deviation angle, and bonds the crystal rod to the upper surface of the buffer plate.

[0004] The inventors discovered during daily use that, due to quality issues during crystal pulling, defective crystal rods of varying lengths need to be cut and discarded. After cutting, a large number of good silicon rods of different lengths remain. However, these rods are limited by the minimum processing length of the squaring equipment and cannot be processed individually. Therefore, it is necessary to use an adhesive to bond and cure crystal rods of different lengths and diameters to meet the minimum processing requirements of subsequent equipment. Existing bonding devices mostly use V-shaped sliding guide grooves and pressure plates, which have problems such as high difficulty in aligning crystal wires, insufficient centering accuracy, and the possibility of eccentricity. For crystal rods of different diameters, the structure is fixed and cannot be adjusted. Therefore, a device that can adjust the height and position of the crystal wires is a valuable solution. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a device and method for bonding crystal rods of different diameters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device and method for bonding crystal rods of different diameters, comprising a frame, two crystal rod bodies, and an auxiliary structure. A top plate is fixedly connected to the upper end of the frame. Two support plates are fixedly connected inside the frame. An adjustment component is installed on one side of the two support plates that are close to each other. A frame plate is installed on the upper end of the adjustment component. An auxiliary structure is provided on the upper surface of the top plate. The auxiliary structure includes a bracket, which is fixedly connected to the top plate. A cylinder is installed on the upper end of the bracket. A drive shaft is installed at the output end of the cylinder. A push plate is fixedly connected to the output end of the drive shaft. A connecting piece is fixedly connected to the upper surface of the top plate. Two connecting blocks are fixedly connected to the upper surface of the connecting piece. A sliding rod is fixedly connected to one side of the two connecting blocks that are close to each other. The sliding rod is slidably connected to the push plate. Two support blocks are fixedly connected to the upper surface of the top plate. Several connecting shafts are rotatably connected to the inner wall of the frame plate. Two opposing inclined blocks are slidably connected to the arc surface of the rotating shaft.

[0007] By adopting this preferred solution, when two crystal rods need to be placed and bonded, the position of the frame plate can be adjusted by adjusting the component to ensure precise alignment of the two crystal rod bodies. At the same time, the cylinder-driven transmission shaft in the auxiliary structure drives the push plate to slide smoothly along the slide bar. The push plate and the inclined block cooperate to apply stable pressure to the crystal rod body, ensuring that the crystal rod maintains accurate position and good fit during the bonding process. This effectively improves the accuracy and stability of crystal rod bonding and avoids bonding quality problems caused by positional deviation or uneven pressure.

[0008] Preferably, the cross-section of the inclined block is trapezoidal, and the inclined block is a silicone block.

[0009] Preferably, the slide bar has a circular cross-section and is made of stainless steel.

[0010] By adopting this preferred solution, the slide bar can limit the push plate, preventing the push plate from shifting during use.

[0011] Preferably, a protective pad, which is a rubber pad, is fixedly connected to the side of the push plate near the cylinder.

[0012] By adopting this preferred solution, the protective pad can limit the crystal rod body and prevent the crystal rod body from shifting when it is pushed.

[0013] Preferably, the two crystal rod bodies are respectively disposed between the two support blocks and between the two sets of inclined blocks, and the cross-section of the crystal rod is circular.

[0014] Preferably, the upper surface of the top plate is provided with a fixing structure, the fixing structure including two slide rails, the two slide rails being fixedly connected to the top plate, a slider being slidably connected to the inner wall of the slide rails, a connecting plate being fixedly connected to the side of the two sliders that are far apart from each other, a screw being threadedly connected to the inner wall of the connecting plate, a connecting plate being fixedly connected to the end of the slider that is far away from the support block, and a positioning plate being fixedly connected to the end of the connecting plate that is far away from the slider.

[0015] By adopting this preferred solution, when it is necessary to position the crystal rod body on the support block, the screw can be rotated to push the slider along the slide rail under the action of the thread on the inner wall of the connecting plate. The slider drives the connecting plate and the positioning plate to move synchronously until the positioning plate is in close contact with the surface of the crystal rod body. Thus, the crystal rod body is clamped and fixed from both sides by the two positioning plates, which effectively prevents the crystal rod body from shifting during the bonding process, improves the stability of the crystal rod body placement, and ensures the accuracy of subsequent processing operations.

[0016] Preferably, a limiting rod is fixedly connected inside the slide rail, and the limiting rod is slidably connected to the slider.

[0017] By adopting this preferred solution, the limiting rod can limit the slider, preventing the slider from deviating when sliding on the inner wall of the slide rail.

[0018] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to one end of the screw near the slide rail.

[0019] By adopting this preferred solution, the anti-slip pad can increase the friction between the screw and the slide rail, thus preventing the screw from sliding when it is fixed to the slide rail.

[0020] Preferably, the frame plate has an adjustment structure at the end away from the support block. The adjustment structure includes a fixing member, which is fixedly connected to the frame plate. A threaded tube is rotatably connected to the inner wall of the fixing member. Opposite threads are formed on the inner walls of both ends of the threaded tube. A lead screw is rotatably connected to the inner walls of both ends of the threaded tube. A mounting plate is fixedly connected to the end of the lead screw away from the threaded tube. Two connecting rings are slidably connected to the arc surface of the rotating shaft. Several connecting rings are divided into two groups. The same auxiliary plate is fixedly connected to the side of each group of connecting rings that are close to each other. The mounting plate is fixedly connected to the connecting rings.

[0021] By adopting this preferred solution, when the position of the inclined block needs to be adjusted, the threaded tube can be rotated. Since the inner walls of the two ends of the threaded tube have opposite threads, it will drive the lead screws at both ends to move in opposite directions. Then, through the mounting plate, the connecting ring will slide on the arc surface of the rotating shaft, so that the auxiliary plate pushes the inclined block to change position, thereby adapting to the clamping requirements of crystal rod bodies of different diameters and improving the versatility and adjustment flexibility of the device.

[0022] Preferably, the arc surface of the threaded ring is provided with a plurality of slots, and the plurality of slots are evenly distributed on the threaded ring.

[0023] By adopting this preferred solution, the groove can increase the friction between the hand and the threaded ring, thus preventing slippage when rotating the threaded ring.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by setting an auxiliary structure, stable pressure and precise guidance are achieved during the crystal rod bonding process. When two crystal rod bodies need to be placed and bonded, the position of the frame plate is first adjusted by adjusting the component, so that the two crystal rod bodies to be bonded can be precisely aligned, laying the foundation for subsequent bonding processes.

[0025] 2. In this invention, by setting a fixing structure, the crystal rod body on the support block can be easily and stably positioned. After the crystal rod body is placed on the support block, to prevent it from shifting due to external force or its own weight during the bonding process, thus affecting the bonding accuracy, the fixing structure can be operated. Specifically, by rotating the screw threaded to the inner wall of the connecting plate, the screw will move towards the slide rail under the action of the thread. As the screw continues to rotate, it will push the slider to slide along the inner wall of the slide rail.

[0026] 3. In this invention, by setting an adjustment structure, the position of the inclined block can be easily adjusted according to the crystal rod body of different diameters to adapt to the clamping requirements of various specifications of crystal rods. The position of the inclined block can be flexibly adjusted according to the actual diameter of the crystal rod body, so that the inclined block can fit tightly against the crystal rod body of different diameters, ensuring effective clamping of the crystal rod body and avoiding problems such as unstable clamping or incompatibility due to differences in crystal rod diameter. This significantly improves the compatibility and applicability of the device to crystal rods of different specifications. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, such as Figure 1-6 As shown, the present invention provides a device and method for bonding crystal rods of different diameters, including a frame 1, two crystal rod bodies 9 and an auxiliary structure 6. A top plate 3 is fixedly connected to the upper end of the frame 1. Two support plates 2 are fixedly connected inside the frame 1. An adjustment component 4 is installed on the side of the two support plates 2 that are close to each other. A frame plate 5 is installed on the upper end of the adjustment component 4. An auxiliary structure 6 is provided on the upper surface of the top plate 3. A fixing structure 7 is provided on the upper surface of the top plate 3. An adjustment structure 8 is provided at the end of the frame plate 5 away from the support block 602.

[0032] The following section will explain the specific settings and functions of its auxiliary structure 6, fixing structure 7, and adjusting structure 8.

[0033] like Figure 2 and Figure 3As shown, the auxiliary structure 6 includes a bracket 601, which is fixedly connected to the top plate 3. A cylinder 606 is installed at the upper end of the bracket 601. A transmission shaft 609 is installed at the output end of the cylinder 606. A push plate 603 is fixedly connected to the output end of the connecting shaft 607. A connector 611 is fixedly connected to the upper surface of the top plate 3. Two connecting blocks 604 are fixedly connected to the upper surface of the connector 611. A slide rod 605 is fixedly connected to the side of the two connecting blocks 604 that are close to each other. The slide rod 605 is slidably connected to the push plate 603. Two support blocks 602 are fixedly connected to the upper surface of the top plate 3. Several connecting shafts 607 are rotatably connected to the inner wall of the frame plate 5. Two opposing inclined blocks 608 are slidably connected to the arc surface of the rotating shaft. When two crystal rods need to be placed and bonded, the position of the frame plate 5 can be adjusted by adjusting component 4 to ensure precise alignment of the two crystal rod bodies 9. Simultaneously, the cylinder 606 in the auxiliary structure 6 drives the transmission shaft 609 to smoothly slide the push plate 603 along the slide rod 605. The push plate 603, in conjunction with the inclined block 608, applies stable pressure to the crystal rod body 9, ensuring accurate positioning and good fit during bonding. This effectively improves the precision and stability of crystal rod bonding, avoiding bonding quality problems caused by positional misalignment or uneven pressure. The inclined block 608 has a trapezoidal cross-section and is made of silicone. The slide rod 605 has a circular cross-section and is made of stainless steel. The slide rod 605 can limit the push plate 603, preventing it from shifting during use. A protective pad 610, made of rubber, is fixedly connected to the side of the push plate 603 closest to the cylinder 606. The protective pad 610 can limit the crystal rod body 9 to prevent the crystal rod body 9 from shifting when it is pushed. The two crystal rod bodies 9 are respectively set between the two support blocks 602 and between the two sets of inclined blocks 608. The cross-section of the crystal rod is circular.

[0034] like Figure 4 and Figure 5As shown, the fixed structure 7 includes two slide rails 71, which are fixedly connected to the top plate 3. A slider 75 is slidably connected to the inner wall of the slide rail 71. A connecting plate 73 is fixedly connected to the side of the two sliders 75 that is away from each other. A screw 74 is threadedly connected to the inner wall of the connecting plate 73. A connecting plate 77 is fixedly connected to the end of the slider 75 that is away from the support block 602. A positioning plate 76 is fixedly connected to the end of the connecting plate 77 that is away from the slider 75. When it is necessary to position the crystal rod body 9 on the support block 602, the screw 74 can be rotated, causing the screw 74 to push the slider 75 along the slide rail 71 under the action of the thread on the inner wall of the connecting plate 73. The slider 75 drives the connecting plate 77 and the positioning plate 76 to move synchronously until the positioning plate 76 is in close contact with the surface of the crystal rod body 9. Thus, the two positioning plates 76 clamp and fix the crystal rod body 9 from both sides, effectively preventing the crystal rod body 9 from shifting during the bonding process, improving the stability of the crystal rod body 9, and ensuring the accuracy of subsequent processing operations. The slide rail 71 is internally fixedly connected to a limit rod 72, which is slidably connected to the slider 75. The limit rod 72 can limit the slider 75 to prevent it from shifting when sliding on the inner wall of the slide rail 71. The end of the screw 74 near the slide rail 71 is fixedly connected to an anti-slip pad 78, which is a rubber pad. The anti-slip pad 78 can increase the friction between the screw 74 and the slide rail 71, preventing the screw 74 from sliding when it is fixed to the slide rail 71.

[0035] like Figure 1 and Figure 6 As shown, the adjustment structure 8 includes a fixing member 86, which is fixedly connected to the frame plate 5. A threaded tube 85 is rotatably connected to the inner wall of the fixing member 86. Opposite threads are opened on the inner walls of both ends of the threaded tube 85. A lead screw 84 is rotatably connected to the inner walls of both ends of the threaded tube 85. A mounting plate 83 is fixedly connected to the end of the lead screw 84 away from the threaded tube 85. Two connecting rings 81 are slidably connected to the arc surface of the rotating shaft. Several connecting rings 81 are divided into two groups. The same auxiliary plate 82 is fixedly connected to the side of each group of connecting rings 81 that is close to each other. The mounting plate 83 is fixedly connected to the connecting rings 81. When the position of the wedge block 608 needs to be adjusted, the threaded tube 85 can be rotated. Since the inner walls of both ends of the threaded tube 85 have opposite threads, it will drive the lead screws 84 at both ends to move in opposite directions. This, in turn, will drive the connecting ring 81 to slide on the arc surface of the rotating shaft through the mounting plate 83, so that the auxiliary plate 82 pushes the wedge block 608 to change position, thereby adapting to the clamping requirements of crystal rod bodies 9 of different diameters, improving the versatility and adjustment flexibility of the device. The arc surface of the threaded ring has several slots 87, which are evenly distributed on the threaded ring. The slots 87 can increase the friction between the hand and the threaded ring, preventing slippage when rotating the threaded ring.

[0036] The overall working principle is as follows: when two crystal rods need to be placed and bonded, the position of the frame plate 5 can be adjusted by adjusting component 4 to make the two crystal rod bodies 9 precisely aligned. At the same time, the cylinder 606 in the auxiliary structure 6 drives the transmission shaft 609 to drive the push plate 603 to slide smoothly along the slide rod 605. The push plate 603 cooperates with the inclined block 608 to apply stable pressure to the crystal rod body 9, ensuring that the crystal rod maintains accurate position and good fit during the bonding process, effectively improving the accuracy and stability of crystal rod bonding, and avoiding bonding quality problems caused by position deviation or uneven pressure. The slide rod 605 can limit the push plate 603 to prevent the push plate 603 from deviating during use. The protective pad 610 can limit the crystal rod body 9 to prevent the crystal rod body 9 from deviating when pushed.

[0037] When it is necessary to position the crystal rod body 9 on the support block 602, the screw 74 can be rotated to push the slider 75 along the slide rail 71 under the action of the thread on the inner wall of the connecting plate 73. The slider 75 drives the connecting plate 77 and the positioning plate 76 to move synchronously until the positioning plate 76 is in close contact with the surface of the crystal rod body 9. Thus, the two positioning plates 76 clamp and fix the crystal rod body 9 from both sides, effectively preventing the crystal rod body 9 from shifting during the bonding process, improving the stability of the crystal rod body 9, and ensuring the accuracy of subsequent processing operations. The limiting rod 72 can limit the slider 75 to prevent the slider 75 from shifting when sliding on the inner wall of the slide rail 71. The anti-slip pad 78 can increase the friction between the screw 74 and the slide rail 71 to prevent the screw 74 from sliding when it is abutting and fixed with the slide rail 71.

[0038] When the position of the inclined block 608 needs to be adjusted, the threaded tube 85 can be rotated. Since the inner walls of the two ends of the threaded tube 85 are provided with opposite threads, it will drive the lead screws 84 at both ends to move in opposite directions. Then, through the mounting plate 83, the connecting ring 81 will slide on the arc surface of the rotating shaft, so that the auxiliary plate 82 pushes the inclined block 608 to change its position, thereby adapting to the clamping requirements of crystal rod bodies 9 of different diameters, improving the versatility and adjustment flexibility of the device. The slot 87 can increase the friction between the hand and the threaded ring, preventing slippage when rotating the threaded ring.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
