[0002] Currently, in the semiconductor manufacturing supply chain, end cap assembly of crystal rods (single-crystal silicon rods or compound semiconductor crystal rods) is a critical step before wafer substrate fabrication. Existing end cap assembly is primarily done manually, requiring operators to undergo extensive training to master positioning accuracy and force control techniques. This results in high labor costs and poor stability, limiting production line capacity due to the limited number of skilled workers. Furthermore, manual visual alignment makes it difficult to ensure precise alignment between the end cap and the crystal rod's axis, leading to easy scratches on the crystal rod during assembly. Frequent contact between gloves, tools, and the crystal rod's end face during operation can introduce particulate contamination, further amplifying the contamination risk. Utility Model Content

[0034] like Figures 1 to 5 As shown, a preferred embodiment of the present invention provides a crystal rod end cap assembly device, a rotary transfer platform 10, which is provided with a loading position 11 and a unloading position 12 for placing crystal rods 70.
[0035] The feeding mechanism 20 includes a feeding slide rail 21 and a feeding lifting gripper 22 for holding the crystal rod 70. One end of the feeding slide rail 21 extends to the corresponding upper part of the feeding position 11, and the feeding lifting gripper 22 is slidably connected to the feeding slide rail 21.
[0036] The unloading mechanism 30 includes an unloading slide rail 31 and an unloading lifting gripper 32 for holding the crystal rod 70. One end of the unloading slide rail 31 extends to the corresponding upper part of the unloading position 12, and the unloading lifting gripper 32 is slidably connected to the unloading slide rail 31.
[0037] The end cap feeding mechanism 40 includes a push cylinder 41 and a feeding box 43 for placing the end cap 71. The push cylinder 41 is located on one side of the unloading position 12. The push cylinder 41 is provided with a telescopic push end 42 facing the unloading position 12. The movement direction of the telescopic push end 42 is the same as the extension direction of the crystal rod 70. The feeding box 43 is connected to the telescopic push end 42.
[0038] The crystal ingot end cap assembly device of this utility model includes a loading mechanism 20, a unloading mechanism 30, an end cap feeding mechanism 40, and a rotary transfer platform 10. The rotary transfer platform 10 is provided with a loading position 11 and an unloading position 12 for placing crystal ingots 70. The loading mechanism 20 is located on one side of the loading position 11. The loading mechanism 20 includes a loading slide rail 21 and a loading lifting gripper 22. The loading lifting gripper 22 is used to grip the crystal ingot 70 before processing, slides on the loading slide rail 21 to the corresponding position above the loading position 11 and places the crystal ingot 70 in the loading position 11. The rotary transfer platform 10 rotates the crystal ingot 70 at the loading position 11 to the unloading position. Material position 12 has an end cap feeding mechanism 40 on one side. An end cap 71 is placed in the material box 43. The end cap 71 is moved towards the material position 12 by the push cylinder 41, so that one end of the crystal rod 70 is inserted into the end cap 71, thereby realizing the automatic assembly of the end cap 71 and the crystal rod 70. The unloading lifting gripper 32 moves to the corresponding position above the material position 12 and moves downward to pick up the crystal rod 70 with the end cap 71 assembled. The assembled crystal rod 70 is removed by sliding on the unloading slide rail 31, freeing up the material position 12. The rotating transfer platform 10 is then rotated to the loading position 11 for the next loading of crystal rod 70. The loading of crystal rod 70, the assembly of crystal rod 70 and end cap 71, and the feeding of end cap 71 are all realized by a mechanical transmission structure, which improves the assembly positioning accuracy, reduces the scratch rate of crystal rod 70 during the assembly process, improves the cleanliness of the product assembly process, increases the yield, and improves the assembly efficiency.
[0039] As one embodiment, such as Figure 1 as well as Figure 4 and Figure 5As shown, the feeding slide rail 21 includes a feeding bracket and a feeding linear transmission mechanism. The feeding linear transmission mechanism is connected to the feeding bracket, which supports the feeding linear transmission mechanism. The feeding linear transmission mechanism includes a motor, a coupling, a lead screw, and a slider. The motor output shaft is connected to the lead screw via the coupling. The lead screw is rotatably connected to the feeding bracket to achieve lead screw positioning. The slider is threadedly connected to the lead screw, and the rotation of the lead screw drives the slider to rotate. The feeding lifting gripper 22 is connected to the slider. The unloading slide rail 31 has the same structure as the feeding slide rail 21.
[0040] As one embodiment, such as Figure 1 as well as Figure 4 and Figure 5 As shown, the loading lifting gripper 22 includes a lifting cylinder, clamping plates, and a holding cylinder. One end of the lifting cylinder is connected to the slider, and the holding cylinder is connected to the drive end of the lifting cylinder. The holding cylinder is a double-rod cylinder that can extend and retract relative to each other on both sides. Clamping plates are respectively connected to the drive ends on opposite sides of the holding cylinder. By extending and retracting the two drive ends of the holding cylinder, the two clamping plates can be moved closer or further apart, thereby achieving the clamping and unloading of the crystal ingot 70. The loading lifting gripper 22 has the same structure as the unloading lifting gripper 32.
[0041] As one embodiment, such as Figure 1 As shown, end cap feeding mechanisms 40 are placed on opposite sides of the rotary transfer platform 10, thereby simultaneously assembling end caps 71 at both ends of the crystal rod 70, improving the assembly efficiency of the end caps 71.
[0042] Furthermore, such as Figures 1 to 2 As shown, the rotary transfer platform 10 includes a support platform 13 and a rotary drive 14. The support platform 13 is tractively connected to the upper end of the rotary drive 14. The loading position 11 and the unloading position 12 are respectively disposed opposite to each other at both ends of the support platform 13. The loading position 11 and the unloading position 12 are used to place crystal ingots 70. The rotary drive 14 drives the support platform 13 to rotate, so as to rotate the crystal ingots 70 on the loading position 11 to the unloading position 12. At the same time, after the crystal ingots 70 on the unloading position 12 are assembled and removed, the position on the support platform 13 is vacated. The rotary drive 14 rotates the vacated position to the loading position 11 to place the crystal ingots 70 to be assembled.
[0043] As one embodiment, such as Figures 1 to 2 As shown, the rotary drive 14 is located between the loading position 11 and the unloading position 12. The rotary drive 14 is a motor, which is connected to the bearing platform 13 through the drive end of the motor, thereby driving the bearing platform 13 to rotate.
[0044] As one embodiment, such as Figures 1 to 2As shown, the rotation drive 14 is connected to the middle of the support platform 13 so that the support platform 13 is subjected to more uniform force when rotating.
[0045] Furthermore, such as Figures 1 to 2 As shown, the loading position 11 is provided with a loading groove 15 for carrying crystal ingots 70, and the opening of the loading groove 15 faces the loading lifting gripper 22. The unloading position 12 is provided with a unloading groove 16 for carrying crystal ingots 70, and the opening of the unloading groove 16 faces the unloading lifting gripper 32. The loading lifting gripper 22 is located above the loading groove 15, and the opening of the loading groove 15 faces the loading lifting gripper 22, which facilitates the placement of the crystal ingots 70 held by the loading lifting gripper 22 into the loading groove 15. The unloading lifting gripper 32 is located above the unloading groove 16, and the opening of the unloading groove 16 faces the unloading lifting gripper 32, which facilitates the unloading lifting gripper 32 to pick up and remove the assembled crystal ingots 70 from the unloading groove 16, freeing up the unloading groove 16 for the loading of the next crystal ingot 70 to be assembled. The loading groove 15 and the unloading groove 16 have a simple structure and are easy to manufacture, which helps to reduce production costs. It should be noted that the side closer to the feeding mechanism 20 is the feeding trough 15, and the side closer to the unloading mechanism 30 is the unloading trough 16. The bearing platform 13 is rotated by the rotation drive 14 to convert the empty unloading trough 16 into the feeding trough 15, and at the same time, the feeding trough 15 containing the crystal rod 70 to be assembled is rotated to the unloading position 12 to be converted into the unloading trough 16.
[0046] As one embodiment, such as Figures 1 to 2 As shown, the shapes of the loading tank 15 and the unloading tank 16 are set to correspond to the outer circumference shape of the crystal rod 70, so as to make the placement of the crystal rod 70 more stable and reduce the probability of the crystal rod 70 falling off.
[0047] As one embodiment, such as Figures 1 to 2 As shown, the feeding trough 15 and the unloading trough 16 are U-shaped troughs.
[0048] Furthermore, such as Figure 1 and Figure 3 As shown, the discharge box 43 is provided with a discharge chamber 44, a feeding port 45, and an adsorption port 46 for communicating with negative pressure. The feeding port 45 and the adsorption port 46 are respectively connected to the discharge chamber 44, and the feeding port 45 is set towards the rotary transfer platform 10. The discharge chamber 44 is used to accommodate the end cap 71, and the end cap 71 is adsorbed and positioned by the adsorption port 46 communicating with negative pressure to prevent the end cap 71 from falling off. The feeding port 45 is set towards the rotary transfer platform 10, and the opening of the end cap 71 faces the unloading position 12. Then, by pushing the cylinder 41 towards the rotary transfer platform 10, the end cap 71 is pushed towards the end of the crystal rod 70, and the end cap 71 is assembled onto one end of the crystal rod 70.
[0049] Furthermore, such as Figure 1 and Figure 3As shown, the end cap feeding mechanism 40 also includes a feeding conduit 48. One end of the feeding conduit 48 has a feeding port 49, and the other end has a discharging port 50. The upper end of the discharge box 43 has an inlet 47 communicating with the discharge chamber 44, and the discharging port 50 is located above the corresponding inlet 47. The feeding conduit 48 has an inlet 49 and a discharging port 50 at both ends, and the feeding conduit 48 guides the feeding of the end cap 71. The end cap 71 is placed into the feeding conduit 48 through the inlet 49, and the end cap 71 slides along the feeding conduit 48. The discharging port 50 of the feeding conduit 48 is connected to the inlet 47 of the discharge chamber 44. The end cap 71 enters the discharge chamber 44 sequentially from the discharging port 50 and the inlet 47, and is positioned by the suction port 46 in the discharge chamber 44. The feeding conduit 48 improves the positioning accuracy of the end cap 71 during feeding.
[0050] As one embodiment, such as Figure 1 and Figure 3 As shown, the dimensions of the discharge chamber 44, the feed conduit 48 and the end cap 71 are set in a corresponding manner, and the thickness of the feed conduit 48 is set in a corresponding manner to the dimensions of the end cap 71, so that each end cap 71 can enter the feed conduit 48 in sequence, and only one end cap 71 enters the discharge chamber 44 at a time.
[0051] Furthermore, such as Figure 1 and Figure 3 As shown, the end cap feeding mechanism 40 also includes a feeding rack 51. The feeding rack 51 includes a support rod 52, a guide rod 53, a limiting plate 55, and a base plate 56. The base plate 56 is connected to one end of the support rod 52, and the limiting plate 55 is connected to the other end of the support rod 52 to form a feeding limiting cavity 57. One side of the feeding limiting cavity 57 is connected to the feeding port 49, and the guide rod 53 is connected to the side of the limiting plate 55 away from the feeding limiting cavity 57 to form an end cap storage area 54. The feed rack 51 is used to store the end caps 71 to be assembled. A support rod 52 is located between the base plate 56 and the limiting plate 55. Both ends of the support rod 52 are connected to the base plate 56 and the limiting plate 55 respectively to form a feed limiting cavity 57. The feed limiting cavity 57 limits the height of the two end caps 71, ensuring that only one end cap 71 is pushed into the feed guide tube 48 through the feed inlet 49 at a time. A guide rod 53 is connected to the end of the limiting plate 55 facing away from the base plate 56. The guide rod 53 forms an area to accommodate the end caps 71, allowing multiple end caps 71 to be neatly stacked along the direction of the guide rod 53. Under gravity, when the bottom end cap 71 is pushed away, the upper end caps 71 move downwards along the guide rod 53.
[0052] As one embodiment, the limiting plate 55 has a through hole, and the end cap storage area 54 and the feeding limiting cavity 57 are connected through the through hole so that the end cap 71 of the end cap storage area 54 can fall into the feeding limiting cavity 57 through the through hole.
[0053] In one embodiment, the guide rod 53 is a tube, and an end cap storage area 54 is formed inside the tube. The end cap 71 is placed in the end cap storage area 54 for stacking the end caps 71.
[0054] As one embodiment, such as Figure 1 and Figure 3 As shown, there are multiple guide rods 53, which define the end cap storage area 54. The end caps 71 are stacked in the end cap storage area 54.
[0055] As one embodiment, such as Figure 1 and Figure 3 As shown, the limiting plate 55 is square, and four guide rods 53 are provided. One guide rod 53 is connected to each of the four corners of the limiting plate 55, and the four guide rods 53 define the end cap storage area 54.
[0056] Furthermore, such as Figure 1 and Figure 3 As shown, the end cap feeding mechanism 40 also includes a feeding cylinder 58, which is connected to the base plate 56 and is arranged opposite to the feeding port 49. The feeding cylinder 58 pushes the bottom end cap 71 in the feeding limiting cavity 57 toward the feeding port 49, and the end cap 71 enters the feeding guide tube 48, realizing the automatic feeding of the end cap 71.
[0057] Furthermore, such as Figure 1 and Figure 3 As shown, the end cap feeding mechanism 40 also includes a first feeding baffle 59 and a second feeding baffle 60 connected to the base plate 56. The first feeding baffle 59 and the second feeding baffle 60 are respectively located between the support rod 52 and the feed inlet 49, forming a feeding limiting channel 61. One end of the feeding limiting channel 61 is connected to the feeding limiting cavity 57, and the other end is connected to the feed inlet 49. The first feeding baffle 59 and the second feeding baffle 60 form the feeding limiting channel 61 so that after the end cap 71 is pushed out from the feeding limiting cavity 57, it can move smoothly to the feeding guide tube 48 within the feeding limiting channel 61, preventing the end cap 71 from shifting and falling during the movement, thus improving feeding stability.
[0058] Furthermore, such as Figure 1 and Figure 3As shown, the end cap feeding mechanism 40 also includes a baffle 62 and a baffle drive 63. The baffle drive 63 is kinetically connected to the baffle 62. The baffle 62 is located between the feeding port 45 and the unloading position 12, and is also located below the corresponding outlet 50. The baffle 62 is moved by the baffle drive 63 to the corresponding front of the feeding port 45 and below the corresponding outlet 50, thereby preventing the end cap 71, which slides from the outlet 50 into the discharge chamber 44, from tilting forward, thus improving the positioning stability of the end cap 71 in the discharge chamber 44. When the push cylinder 41 needs to push the end cap 71 toward the unloading position 12, the baffle drive 63 drives the baffle 62 away from the discharge box 43.
[0059] In one embodiment, the baffle drive 63 is a cylinder. Cylinders are prior art and will not be described in detail here.
[0060] Furthermore, such as Figure 1 As shown, the feeding mechanism 20 also includes a feeding fixture 24, which has a first placement groove 25 for placing crystal rods 70. The first placement groove 25 is located below the feeding lifting gripper 22. The feeding fixture 24 is used to place the crystal rods 70 to be assembled. The extending direction of the feeding fixture 24 is the same as the extending direction of the feeding slide rail 21, so that the feeding lifting gripper 22 can clamp the crystal rods 70 in the feeding fixture 24 while sliding along the feeding slide rail 21. The extending direction of the first placement groove 25 is the same as the extending direction of the feeding groove 15, so that after the feeding lifting gripper 22 clamps the crystal rods 70 from the first placement groove 25, it can put the crystal rods 70 into the feeding groove 15 without rotation, reducing the difficulty of operation.
[0061] The unloading mechanism 30 also includes an unloading fixture 34. The unloading fixture 34 has a second placement slot 35 for placing the crystal ingot 70, located below the unloading lifting gripper 32. The unloading fixture 34 is used to place the crystal ingot 70 with the end cap 71 assembled. The extending direction of the unloading fixture 34 is the same as the extending direction of the unloading slide rail 31, so that the unloading lifting gripper 32 slides along the unloading slide rail 31 and places the crystal ingot 70 clamped in the unloading slot 16 into the unloading fixture 34. The extending direction of the second placement slot 35 is the same as the extending direction of the unloading slot 16, so that after the unloading lifting gripper 32 clamps the crystal ingot 70 from the unloading slot 16, it can place the crystal ingot 70 into the second placement slot 35 without rotation, reducing operational difficulty.
[0062] In summary, this utility model embodiment provides a crystal rod end cap assembly device, including a loading mechanism 20, a unloading mechanism 30, an end cap feeding mechanism 40, and a rotary transfer platform 10. The rotary transfer platform 10 is provided with a loading position 11 and an unloading position 12 for placing crystal rods 70. The loading mechanism 20 is located on one side of the loading position 11. The loading mechanism 20 includes a loading slide rail 21 and a loading lifting gripper 22. The loading lifting gripper 22 is used to grip the crystal rod 70 before processing, slides on the loading slide rail 21 to the corresponding position above the loading position 11, and places the crystal rod 70 in the loading position 11. The rotating transfer platform 10 then moves the crystal rod at the loading position 11. The crystal rod 70 rotates to the unloading position 12. An end cap feeding mechanism 40 is located on one side of the unloading position 12. An end cap 71 is placed in the unloading box 43. A push cylinder 41 moves the end cap 71 towards the unloading position 12, allowing one end of the crystal rod 70 to be inserted into the end cap 71, thus achieving automatic assembly of the end cap 71 and the crystal rod 70. The unloading lifting gripper 32 moves to the corresponding position above the unloading position 12 and moves downward to grip the crystal rod 70 with the assembled end cap 71. The assembled crystal rod 70 is then removed via the unloading slide rail 31, freeing up the unloading position 12. The rotating transfer platform 10 then rotates to the loading position 11 for the next loading of the crystal rod 70. The loading of the crystal rod 70, the assembly of the crystal rod 70 with the end cap 71, and the feeding of the end cap 71 are all achieved through a mechanical transmission structure, improving assembly positioning accuracy, reducing the scratch rate of the crystal rod 70 during assembly, improving the cleanliness of the product assembly process, and increasing the yield.
[0063] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
