Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, and in particular to a crystal feeding mechanism. Background Technology

[0002] Semiconductor devices, as core components of modern electronic products such as computers, smartphones, and communication equipment, not only realize key functions such as signal amplification, data processing and storage, but also drive the development of high-speed computing and massive information processing, and are therefore widely used in many fields.

[0003] In practical production applications, semiconductor manufacturing is a complex and highly precise process involving numerous steps, among which crystal dicing is particularly critical. This step requires precisely dividing single-crystal silicon ingots or other semiconductor materials into wafers, and then further dicing the wafers into individual chip units. This process directly determines the quality of the finished chip and has a significant impact on production efficiency and cost-effectiveness.

[0004] Currently, common crystal cutting methods include mechanical blade cutting, laser cutting, and plasma cutting. In existing technologies, crystal picking during cutting usually relies on manual operation or mechanical metal clamps. The above two traditional picking methods have problems: (1) Manual operation: not only is it inefficient, but it is also easy to introduce human error, affecting the quality of crystal cutting, thus leading to a decrease in the quality of the finished product; (2) Mechanical metal clamps: its movement direction is singular, which limits the flexibility of picking and cannot adapt to the needs of multi-directional and multi-angle operation, reducing the practicality of the system.

[0005] As the semiconductor manufacturing industry continues to pursue higher precision, efficiency and consistency, traditional material handling methods can no longer meet the stringent requirements of modern production. Therefore, there is an urgent need for a more efficient, flexible and practical material handling mechanism. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] This utility model provides a crystal picking mechanism that can realize automated, multi-directional, and multi-angle crystal picking. It can not only improve picking efficiency and quality, but also operate flexibly and has strong applicability. Of course, it can also be applied to picking other objects with similar shapes, and there is no limitation here.

[0031] Specifically, such as Figure 1As shown, the crystal picking mechanism includes a base 1 and a picking device 2, a lifting device 3, a lateral moving device 4, and a composite rotating device 5 disposed on the base 1. The picking device 2 can be used to pick up crystals; the picking can be clamping, sucking, or sticking. Correspondingly, the picking device 2 can be a gripper, suction cup, or adhesive head. The lifting device 3 can be used to drive the picking device 2 to move vertically. The lateral moving device 4 can be used to drive the picking device 2 to move laterally. In this embodiment, the lateral movement refers to left-right movement, or forward-backward movement, or simultaneous forward-backward-left-right movement. The composite rotating device 5 includes a first rotating component 51 and a second rotating component 52. The rotating assembly 52 and the rotating arm 53 connecting the first rotating assembly 51 and the second rotating assembly 52; the first rotating assembly 51 is movably connected to the lifting device 3 or the lateral moving device 4, and can move longitudinally or laterally under the drive of the lifting device 3 or the lateral moving device 4, and can also drive the rotating arm 53 to rotate. For example, in this embodiment, the first rotating assembly 51 is movably connected to the lateral moving device 4, and the first rotating assembly 51 can move laterally under the drive of the lateral moving device 4, and can also make the rotating arm 53 rotate; the second rotating assembly 52 is movably connected to the material picking device 2, and can also drive the material picking device 2 to rotate around an axis; such as Figure 2 The diagram shows the crystal picking mechanism in use. Driven by the lifting device 3, the horizontal moving device 4, and the composite rotating device 5, the picking position and picking angle of the picking device 2 can be adjusted.

[0032] The crystal picking mechanism with the above structure can pick up the crystal through the picking device 2. The lifting device 3, the traversing device 4 and the first rotating component 51 can move the picking device 2 flexibly and accurately to any picking position to achieve multi-directional picking. The second rotating component 52 can make the picking device 2 rotate around the axis to adjust the picking angle and achieve multi-angle picking. Thus, it realizes the automation, multi-directional and multi-angle picking of crystals, which can not only improve picking efficiency and picking quality, but also be flexible in operation and highly applicable.

[0033] In some embodiments, the lifting device 3 includes at least two parallel hydraulic telescopic rods. The hydraulic telescopic rod is a height adjustment device widely used in various mechanical equipment. It has strong load-bearing capacity, smooth operation, high control precision and high reliability, which can improve the reliability of the crystal picking mechanism. Moreover, the provision of at least two parallel hydraulic telescopic rods can further enhance the reliability.

[0034] In some embodiments, such as Figure 3 , Figure 4As shown, the transverse movement device 4 includes a transverse guide rail 41, a transverse slider 42, a transverse screw 43, and a transverse drive component 44. Specifically, the transverse slider 42 is slidably connected to the transverse guide rail 41, and the length direction of the transverse guide rail 41 is parallel to the axial direction of the transverse screw 43, so that the sliding direction of the transverse slider 42 is also parallel to the axial direction of the transverse screw 43. The transverse slider 42 is threadedly connected to the outer wall of the transverse screw 43, and the transverse screw 43 can rotate around its axis under the drive of the transverse drive component 44. In this embodiment, the transverse screw 43 is disposed in a first housing with a top opening, and the transverse drive component 44 is disposed in the... On the side of the first housing, the transverse screw 43 can be driven to rotate around its axis within the first housing. The transverse guide rail 41 is located at the top opening of the first housing. The transverse slider 42 is divided into an upper part and a lower part. The upper part is located on the top surface of the first housing and is fixedly connected to the first rotating assembly 51. The lower part is located inside the first housing and is threadedly connected to the outer wall of the transverse screw 43. When the transverse screw 43 rotates around its axis within the first housing under the drive of the transverse drive component 44, it will drive the transverse slider 42, which is threadedly connected to the transverse screw 43, to slide on the transverse guide rail 41, thereby realizing the function of transverse movement.

[0035] The crystal feeding mechanism with the above structure can achieve high-precision, high-reliability and high-efficiency linear motion control and realize lateral movement through the cooperation between the transverse guide rail 41, transverse slider 42, transverse screw 43 and transverse drive component 44.

[0036] In some embodiments, such as Figure 6 As shown, the material handling device 2 is equipped with a telescopic component 21. The telescopic component 21 can control the material handling head to extend or retract along the material handling direction. For example, if the material handling direction is downward, the material handling head can be controlled to move longitudinally, that is, up and down. If the material handling direction is to the side, the material handling head can be controlled to move forward and backward or left and right.

[0037] The crystal picking mechanism with the above structure can further improve the picking flexibility of the crystal picking mechanism by setting the telescopic component 21 on the picking device 2, so that the crystal picking mechanism can be applied to picking in more different working conditions and has higher applicability.

[0038] In some embodiments, the material handling device 2 includes a left clamping plate 22 and a right clamping plate 23, which are adapted to the crystal and can clamp the crystal. The left clamping plate 22 and the right clamping plate 23 can move closer to or further away from each other to achieve clamping or loosening. Preferably, the clamping plate material can be selected from materials that are harmless to the surface of the crystal, such as soft rubber or Teflon coating, which can reduce scratches or contamination on the crystal surface.

[0039] The crystal picking mechanism with the above structure achieves the picking of the crystal through the cooperation between the left clamping plate 22 and the right clamping plate 23. It has a simple structure, is easy to clean and maintain, can be applied to picking up various crystal morphologies, and has high picking efficiency and is safe and reliable.

[0040] In some embodiments, the material handling device 2 further includes a clamping control component 24 for controlling the clamping action. The clamping control component 24 includes a clamping guide rail 241, a clamping screw 242, a left slider 243, a right slider 244, and a clamping drive component 245. The left slider 243 and the right slider 244 are slidably connected to the clamping guide rail 241, and the length direction of the clamping guide rail 241 is parallel to the axial direction of the clamping screw 242, so that the sliding direction of the left slider 243 and the right slider 244 is also parallel to the axial direction of the clamping screw 242. The clamping screw 242 is a mirror screw (mirror image screw). The screw is a specially designed screw, characterized by its threaded portion being divided into two opposite directions in the middle, one end being a left-hand thread and the other end a right-hand thread, making the thread directions at both ends of the screw opposite, suitable for applications requiring bidirectional synchronous movement. The left slider 243 and right slider 244 are respectively threaded to the outer walls of the left and right ends of the clamping screw 242 (i.e., the left slider 243 and right slider 244 are respectively threaded to the left-hand and right-hand threads of the clamping screw 242); under the drive of the clamping drive component 245, the clamping screw 242 can rotate around its axis. Rotational motion; the left clamping plate 22 and the right clamping plate 23 are respectively disposed on the left slider 243 and the right slider 244, and can move with the left slider 243 and the right slider 244; in this embodiment, the clamping screw 242 is disposed in a second housing with an open bottom, and the clamping drive component 245 is disposed on the side of the second housing, which can drive the clamping screw 242 to rotate around the axis of the clamping screw 242 within the second housing, the clamping guide rail 241 is located at the bottom opening of the second housing, and the left slider 243 and the right slider 244 are each divided into an upper part and a lower part, wherein the lower part... The upper part is located below the bottom surface of the second housing and is connected to the left clamping plate 22 and the right clamping plate 23 respectively. The upper part is located inside the second housing and is threaded to the left and right ends of the clamping screw 242 respectively. When the clamping screw 242 rotates around the axis inside the second housing under the drive of the clamping drive component 245, it will drive the left slider 243 and the right slider 244, which are threaded to the left and right ends of the clamping screw 242, to move in opposite directions on the clamping guide rail 241, that is, to move closer to each other or further away from each other, thereby driving the left clamping plate 22 and the right clamping plate 23 to move closer to each other or further away from each other, so as to achieve clamping and releasing.

[0041] The crystal picking mechanism with the above structure can achieve high-precision, high-reliability and high-efficiency linear motion control through the mutual cooperation between the clamping guide rail 241, clamping screw 242, left slider 243, right slider 244 and clamping drive component 245, so as to realize the clamping and loosening of the left clamping plate 22 and the right clamping plate 23.

[0042] In some embodiments, such as Figure 5 , Figure 6 As shown, the left clamping plate 22 and the right clamping plate 23 are respectively provided with a sensor controller 25. The sensor controller 25 is electrically connected to the clamping drive component 245 and can be used to detect the degree of clamping of the crystal by the left clamping plate 22 and the right clamping plate 23, and to feed back signals to control the start and stop of the clamping drive component 245, thereby adjusting the clamping force of the left clamping plate 22 and the right clamping plate 23.

[0043] The crystal picking mechanism with the above structure can detect the degree of clamping of the crystal by the left clamping plate 22 and the right clamping plate 23 by setting the induction controller 25 on the left clamping plate 22 and the right clamping plate 23 respectively, and adjust the clamping force of the left clamping plate 22 and the right clamping plate 23, thereby avoiding the crystal from being over-clamped and causing scratches, and improving the quality of picking.

[0044] In some embodiments, such as Figure 5 As shown, the induction controller 25 includes a clamping plate connecting rod 251, a sleeve 252, and a sliding collar 253, a spring 254, and a trigger 255 disposed within the sleeve 252. Specifically, the sleeve 252 is horizontally fixedly disposed on the left slider 243 and the right slider 244, respectively. The clamping plate connecting rod 251 is fixedly disposed on the outer sidewalls of the left clamping plate 22 and the right clamping plate 23, respectively, and the length direction of the clamping connecting rod 251 is parallel to the clamping movement direction of the left clamping plate 22 and the right clamping plate 23. The clamping plate connecting rod 251 passes through the sleeve 252 from one end opening. The sliding collar 253 is fixedly sleeved on the outer sidewall of the clamping plate connecting rod 251 and slidably connected to the inner sidewall of the sleeve 252, thereby allowing the clamping plate connecting rod 251 to move left and right within the sleeve 252. The spring 254 is located on the sliding collar 253. 3. Between the other end of the sleeve 252 and the other end of the sleeve 252, the sliding collar 253 can be abutted; the trigger 255 is fixedly set on the other end of the sleeve 252, and is adapted to the position of the clamping plate connecting rod 251. When the left clamping plate 22 and the right clamping plate 23 clamp the crystal, under the reaction force of the crystal, through the transmission of force, the clamping plate connecting rod 251, which is fixedly set on the outer side wall of the left clamping plate 22 and the right clamping plate 23 respectively, begins to compress the spring 254. When the clamping force of the left clamping plate 22 and the right clamping plate 23 reaches the preset force, it will overcome the elastic force of the spring 254 and move towards the trigger 255. The clamping plate connecting rod 251 contacts the trigger 255, and then the trigger 255 sends a control signal to the clamping drive component 245, so that the clamping drive component 245 is turned off, the clamping screw 242 stops rotating and no longer clamps further.

[0045] The crystal picking mechanism with the above structure, through the cooperation between the clamping plate connecting rod 251, sleeve 252, sliding collar 253, spring 254, and trigger 255, can not only detect the clamping degree of the left clamping plate 22 and right clamping plate 23 on the crystal and adjust the clamping force of the left clamping plate 22 and right clamping plate 23 to avoid the crystal being over-clamped and causing scratches, thus improving the quality of picking, but also be more accurate and reliable.

[0046] In some embodiments, the inner surfaces of the left clamping plate 22 and the right clamping plate 23 that contact the crystal are arc surfaces, which provides better clamping effect, is more stable and reliable, and can be applied to clamping crystals of various sizes.

[0047] In some embodiments, the base 1 is further provided with an auxiliary support frame 6 that can increase the bottom force-bearing area, so that the support effect of the base 1 is better and the reliability of the crystal picking mechanism can be further improved.

[0048] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. All equivalent changes made in accordance with the shape, structure and principle of the present utility model should be covered within the protection scope of the present utility model.
