Description

Technical Field

[0001] This invention relates to the field of crystal rod production, specifically to a crystal rod transport anti-drop clamping device. Background Technology

[0002] Crystal rods generally refer to single-crystal silicon crystal rods, which are cylindrical single-crystal materials obtained by melting and crystallizing high-purity silicon raw materials using the Czochralski method or zone melting method. They have orderly internal atomic arrangement, are brittle and hard, and are the basic blanks for preparing silicon wafers and crystals. They need to complete processes such as transfer and loading / unloading in the production line.

[0003] The mainstream production of crystal rods adopts the Czochralski method. High-purity polycrystalline silicon raw materials are loaded into a quartz crucible in a single crystal furnace and melted into silicon melt at high temperature under an argon protective atmosphere. Then, a seed crystal is lowered to contact the silicon melt. The crystal diameter is gradually increased through crystal pulling and shoulder formation processes. Then, the temperature, pulling speed and rotation parameters are precisely controlled to enter the constant diameter growth stage to form a cylindrical single crystal billet. After growth, the crystal rod is cooled and removed from the furnace. The removed crystal rods also need to undergo machining processes such as head and tail trimming, outer circle grinding, and dimensional correction to obtain finished crystal rods with uniform specifications. The finished crystal rods are transferred and stored by equipment and then sent to the slicing process to be processed into silicon wafers.

[0004] Existing silicon rod transport systems mostly rely on the frictional force generated by the clamping arms on both sides to fix the crystal rod. During the transport process, the starting, stopping, acceleration, deceleration or vibration of the equipment can easily cause the crystal rod to slide downwards, resulting in the crystal rod falling directly. Therefore, in order to solve the above problems, a crystal rod transport anti-drop clamping device is proposed. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] Preferably, a linear slide is fixedly connected to the side wall of the support frame; a sliding groove is formed on the inner side wall of the linear slide; a slider is slidably connected in the middle of the sliding groove; and a clamping block is fixedly connected to the side wall of the slider.

[0009] Preferably, a pair of support cylinders are fixedly connected to the bottom end of the support frame; a sliding rod is slidably connected to the middle of the support cylinder; and the sliding rod is connected to the top of the first fixed plate.

[0010] Preferably, a pair of support plates are fixedly connected to the side wall of the support frame; the support plates are located on both sides of the support frame; a dust cover is fixedly connected to the middle of the support plate; the dust cover is connected to the side wall of a pair of fixed blocks.

[0011] Preferably, a second fixing plate is fixedly connected to the side wall of the clamping block; multiple sets of flexible protrusions are fixedly connected to the side wall of the second fixing plate; the top of the flexible protrusions is rounded.

[0013] Preferably, a pair of scrapers are fixedly connected to the side wall of the slider; a pair of scrapers are fixedly connected to the side wall of the fixing block.

[0014] The advantages of this invention are: 1. The present invention discloses a crystal rod transport anti-drop clamping device, wherein the clamping block clamps and fixes the crystal rod from the side, and the baffle supports the crystal rod from the bottom, forming a double fixing structure of side clamp and bottom support. This solves the problem that existing silicon rod transport relies solely on the friction generated by the clamping arms on both sides to fix the crystal rod, which causes the crystal rod to slide downward and fall when the transport vehicle starts, stops, accelerates, decelerates, or vibrates during the transfer process. The motor, the bidirectional screw, and the threaded engagement of the fixing block enable synchronous adjustment of the clamping position of the clamping block, allowing the clamping block to adjust the clamping according to the diameter of the crystal rod. The engagement of the first hydraulic rod and the first fixing plate enables adjustment of the baffle support height, allowing the baffle to be adjusted to a suitable lifting height according to the height of the crystal rod. The engagement of the second hydraulic rod and the baffle enables the extension and retraction of the bottom support, allowing the baffle to provide operating space when loading and unloading the crystal rod, and forming a limit on the bottom end of the crystal rod during transportation.

[0015] 2. The crystal rod transport anti-drop clamping device of the present invention uses the cooperation of linear slide, slide groove and slider to realize secondary adjustment of the clamping position of clamping block, so that the clamping block can be further tightened on the basis of clamping the side wall of support rod, thereby increasing the clamping force on the side wall of crystal rod. At the same time, the clamping block can be adjusted according to the change of crystal rod diameter, reducing the loosening of clamping caused by the difference in crystal rod diameter.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Specific implementation examples are given below.

[0021] like Figures 1 to 5As shown in the embodiment of the present invention, a crystal rod transport anti-drop clamping device includes a transport vehicle 1; a pair of rotating wheels 11 are rotatably connected to the bottom end of the transport vehicle 1; a rotating shaft 12 is rotatably connected to the side wall of the transport vehicle 1; a support frame 13 is fixedly connected to the top end of the rotating shaft 12; a motor 14 is fixedly connected to the side wall of the support frame 13; a bidirectional screw 15 is rotatably connected to the middle of the support frame 13; the output end of the motor 14 is connected to the bidirectional screw 15; a pair of fixing blocks 16 are slidably connected to the middle of the support frame 13; the fixing blocks 16 and the bidirectional screw 15 are connected to each other. 5. Threaded connection; a support rod 17 is fixedly connected to the side wall of the fixing block 16; a pair of clamping blocks 18 are provided on the side wall of the support rod 17; a first hydraulic rod 19 is fixedly connected to the bottom end of the support frame 13; a first fixing plate 110 is fixedly connected to the output end of the first hydraulic rod 19; a second hydraulic rod 111 is fixedly connected to the bottom end of the first fixing plate 110; a baffle 112 is fixedly connected to the output end of the second hydraulic rod 111; during operation, the transport vehicle 1 moves to the crystal rod position, and the rotating wheel 11 rotates to move the transport vehicle 1 to the side of the crystal rod. At this time, the baffle 112 is located on the support. On one side of the frame 13, the support rod 17 is located on both sides of the crystal rod. The starter motor 14 drives the bidirectional screw 15 to rotate. The bidirectional screw 15 drives a pair of fixing blocks 16 to slide synchronously towards the middle. The fixing blocks 16 drive the support rod 17 and the clamping block 18 to move closer to the side wall of the crystal rod. The clamping block 18 contacts the side wall of the crystal rod and clamps and fixes the crystal rod. At the same time, the first hydraulic rod 19 drives the first fixing plate 110 to rise and fall, so that the first fixing plate 110 is adjusted to the same height as the bottom end of the crystal rod. The second hydraulic rod 111 pushes the baffle 112 to move towards the bottom end of the crystal rod. The baffle 112 is moved to the bottom of the crystal rod and forms a lifting support for the bottom of the crystal rod. The crystal rod is transferred with the transport vehicle 1 under the double fixation of the clamping block 18 and the bottom support of the baffle 112. After being transferred to the target position, the second hydraulic rod 111 drives the baffle 112 to retract from the bottom of the crystal rod to the side of the support frame 13. The first hydraulic rod 19 drives the first fixing plate 110 to rise and fall, releasing the support of the baffle 112 on the bottom of the crystal rod. The motor 14 drives the bidirectional screw 15 to rotate in the opposite direction, causing the clamping block 18 to release the clamping of the side wall of the crystal rod and unload the crystal rod.The crystal rod is clamped and fixed from the side by clamping block 18, and supported from the bottom by baffle 112, forming a double fixing structure of side clamping and bottom support. This solves the problem that existing silicon rod transportation relies solely on the friction generated by the clamping arms on both sides to fix the crystal rod. During the transfer process, the crystal rod slides down and falls when the transport vehicle 1 starts, stops, accelerates, decelerates, or vibrates. The threaded engagement of motor 14 with bidirectional screw 15 and fixing block 16 enables synchronous adjustment of the clamping position of clamping block 18, allowing clamping block 18 to adjust the clamping according to the diameter of the crystal rod. The cooperation of first hydraulic rod 19 and first fixing plate 110 enables adjustment of the support height of baffle 112, allowing baffle 112 to be adjusted to a suitable lifting height according to the height of the crystal rod. The cooperation of second hydraulic rod 111 and baffle 112 enables the extension and retraction of the bottom support, allowing baffle 112 to provide operating space when loading and unloading the crystal rod, and forming a limit on the bottom end of the crystal rod during transportation.

[0022] like Figure 5 As shown, a linear slide 2 is fixedly connected to the side wall of the support frame 13; a groove 21 is provided on the inner side wall of the linear slide 2; a slider 22 is slidably connected to the middle of the groove 21; a clamping block 18 is fixedly connected to the side wall of the slider 22; during operation, after the clamping block 18 clamps the side wall of the crystal rod, the linear slide 2 is activated to drive the slider 22 to slide in the groove 21. The slider 22 drives the clamping block 18 to move towards the side wall of the crystal rod, so that the clamping block 18 further tightens the clamping of the crystal rod on the basis of the original clamping of the side wall of the support rod 17; through the cooperation of the linear slide 2, the groove 21 and the slider 22, the clamping position of the clamping block 18 is adjusted for the second time, so that the clamping block 18 can be further tightened on the basis of the clamping of the side wall of the support rod 17, thereby increasing the clamping force on the side wall of the crystal rod. At the same time, the clamping block 18 can be adjusted according to the change of the crystal rod diameter, reducing the loosening of the clamping caused by the difference in crystal rod diameter.

[0023] like Figure 3 As shown, a spring 3 is fixedly connected to the top of the baffle 112; a sleeve rod 31 is fixedly connected to the top of the baffle 112; a fixed disk 32 is fixedly connected to the top of the spring 3 and the sleeve rod 31; during operation, when the second hydraulic rod 111 pushes the baffle 112 to move towards the bottom of the crystal rod, the fixed disk 32 contacts the bottom of the crystal rod. When the crystal rod moves downward during transportation, the spring 3 and the sleeve rod 31 elastically contract under pressure, absorbing and buffering the impact force on the bottom of the crystal rod; the spring 3 and the sleeve rod 31 cooperate to form an elastic buffer structure at the top of the baffle 112, so that the baffle 112 and the bottom of the crystal rod form a flexible contact, reducing the damage to the end face of the crystal rod caused by rigid lifting. At the same time, when the crystal rod moves downward, the sleeve rod 31 elastically deforms to absorb the impact energy, reducing the risk of the crystal rod end face cracking due to impact.

[0024] like Figure 2As shown, a pair of support cylinders 4 are fixedly connected to the bottom end of the support frame 13; a sliding rod 41 is slidably connected to the middle of the support cylinder 4; the sliding rod 41 is connected to the top end of the first fixed plate 110; during operation, when the first hydraulic rod 19 drives the first fixed plate 110 to rise and fall, the sliding rod 41 slides synchronously in the support cylinder 4 with the rise and fall of the first fixed plate 110, providing auxiliary guidance for the rise and fall of the first fixed plate 110; through the sliding cooperation between the support cylinder 4 and the sliding rod 41, the rise and fall movement of the first fixed plate 110 is assisted and guided, so that the first fixed plate 110 remains vertical during the rise and fall process, reducing the tilt of the first fixed plate 110 caused by the rise and fall of the single first hydraulic rod 19, and ensuring the supporting effect of the baffle 112 on the bottom end of the crystal rod.

[0025] like Figure 6 As shown, a pair of support plates 5 are fixedly connected to the side wall of the support frame 13; the support plates 5 are located on both sides of the support frame 13; a dust cover 51 is fixedly connected to the middle of the support plate 5; the dust cover 51 is connected to the side wall of a pair of fixing blocks 16; during operation, when the fixing blocks 16 slide along the support frame 13 under the drive of the bidirectional screw 15, the dust cover 51 expands and contracts synchronously with the movement of the fixing blocks 16, covering the sliding area of ​​the bidirectional screw 15; the support plates 5 and the dust cover 51 cooperate to cover and protect the bidirectional screw 15, reducing the amount of external dust and debris falling on the thread surface of the bidirectional screw 15, causing thread wear or the fixing blocks 16 to slide and jam, thus ensuring the stability between the bidirectional screw 15 and the fixing blocks 16.

[0026] like Figure 5 As shown, a second fixing plate 6 is fixedly connected to the side wall of the clamping block 18; multiple sets of flexible protrusions 61 are fixedly connected to the side wall of the second fixing plate 6; the top of the flexible protrusions 61 is rounded; during operation, when the clamping block 18 moves closer to the side wall of the crystal rod to clamp, the flexible protrusions 61 first contact the side wall of the crystal rod, and the multiple sets of flexible protrusions 61 undergo elastic deformation under the action of clamping force, tightly adhering to the surface of the crystal rod; through the cooperation of the second fixing plate 6 and the flexible protrusions 61, multiple flexible contacts are formed on the clamping surface of the clamping block 18, increasing the friction between the clamping block 18 and the side wall of the crystal rod, and maintaining the stability of the clamping block 18.

[0027] like Figure 6 As shown, a positioning plate 7 is fixed to the side wall of the support frame 13; the positioning plate 7 is located in the middle of the dust cover 51; during operation, the positioning plate 7 supports the middle section of the dust cover 51 during the extension and retraction process, so that the dust cover 51 maintains a horizontal posture in the extended state; by supporting and limiting the middle section of the dust cover 51 through the positioning plate 7, the sag of the dust cover 51 due to its own weight in the middle section is reduced, the poor shielding effect of the dust cover 51 on the bidirectional screw 15 caused by the sag is reduced, and the stability of the dust cover 51 during the extension and retraction process is also maintained.

[0028] like Figures 4 to 5 As shown, a pair of scrapers 8 are fixedly connected to the side wall of the slider 22; a pair of scrapers 8 are fixedly connected to the side wall of the fixing block 16. During operation, when the slider 22 slides in the slide groove 21, the scrapers 8 contact the inner wall of the slide groove 21 to scrape off the dust and impurities attached to the inner wall of the slide groove 21. When the fixing block 16 slides on the support frame 13, the scrapers 8 contact the surface of the bidirectional screw 15 to scrape off the dust and impurities attached to the surface of the bidirectional screw 15. By cleaning the inner wall of the slide groove 21 and the surface of the bidirectional screw 15 respectively during the sliding process of the slider 22 and the fixing block 16, the accumulation of dust and impurities on the surface of the slider 22 and the bidirectional screw 15 is reduced, which leads to an increase in sliding resistance.

[0029] Working principle: The transport vehicle 1 moves to the crystal ingot position, and the rotating wheel 11 rotates, causing the transport vehicle 1 to move to the side of the crystal ingot. At this time, the baffle 112 is located on one side of the support frame 13, and the support rod 17 is located on both sides of the crystal ingot. The start motor 14 drives the bidirectional screw 15 to rotate. The bidirectional screw 15 drives a pair of fixing blocks 16 to slide synchronously towards the middle. The fixing blocks 16 drive the support rod 17 and the clamping block 18 to move closer to the side wall of the crystal ingot. The clamping block 18 contacts the side wall of the crystal ingot and clamps and fixes the crystal ingot. At the same time, the first hydraulic rod 19 drives the first fixing plate 110 to rise and fall, so that the first fixing plate 110 is adjusted to the same height as the bottom end of the crystal ingot. The second hydraulic rod 111 pushes the baffle 112 to move towards the bottom end of the crystal ingot, so that the baffle 112... 2. Move to directly below the bottom of the crystal ingot and provide support for it. The crystal ingot, secured by the clamping block 18 and the bottom support of the baffle 112, is transported by the transport vehicle 1. After reaching the target position, the second hydraulic rod 111 drives the baffle 112 to retract from the bottom of the crystal ingot to one side of the support frame 13. The first hydraulic rod 19 drives the first fixing plate 110 to rise and fall, releasing the support of the baffle 112 on the bottom of the crystal ingot. The motor 14 drives the bidirectional screw 15 to rotate in the opposite direction, causing the clamping block 18 to release its grip on the side wall of the crystal ingot, thus unloading the crystal ingot. After the clamping block 18 clamps the side wall of the crystal ingot, the linear slide 2 is activated, driving the slider 22 to slide within the slide groove 21. The slider 22 moves the clamping block 18 towards the side wall of the crystal ingot, allowing... The clamping block 18 further tightens the clamping of the crystal rod on the side wall of the support rod 17. When the second hydraulic rod 111 pushes the baffle 112 to move towards the bottom of the crystal rod, the fixing plate 32 contacts the bottom of the crystal rod. When the crystal rod moves downward during transportation, the spring 3 and the sleeve rod 31 elastically contract under pressure to absorb and buffer the impact force on the bottom of the crystal rod. When the first hydraulic rod 19 drives the first fixing plate 110 to rise and fall, the slide rod 41 slides synchronously in the support cylinder 4 with the rise and fall of the first fixing plate 110, providing auxiliary guidance for the rise and fall of the first fixing plate 110. When the fixing block 16 slides along the support frame 13 under the drive of the bidirectional screw 15, the dust cover 51 moves synchronously with the movement of the fixing block 16. When the telescopic extension covers the sliding area of ​​the bidirectional screw 15, and the clamping block 18 moves closer to the side wall of the crystal rod to clamp it, the flexible protrusion 61 first contacts the side wall of the crystal rod. Under the action of the clamping force, the multiple sets of flexible protrusions 61 generate elastic deformation and tightly fit the surface of the crystal rod. During the telescopic extension process, the positioning plate 7 supports the middle section of the dust cover 51, so that the dust cover 51 maintains a horizontal posture in the extended state. When the slider 22 slides in the slide groove 21, the scraper 8 contacts the inner wall of the slide groove 21 and scrapes off the dust and impurities attached to the inner wall of the slide groove 21. When the fixing block 16 slides on the support frame 13, the scraper 8 contacts the surface of the bidirectional screw 15 and scrapes off the dust and impurities attached to the surface of the bidirectional screw 15.
