Description

Technical Field

[0001] The utility model relates to the technical field of chip processing and packaging equipment, in particular to a chip alignment device. Background Art

[0002] A chip, also known as a microcircuit, a microchip, or an integrated circuit, refers to a silicon wafer containing an integrated circuit. It is very small in size and is often a part of a computer or other electronic device. It is widely used in fields such as computers, aerospace, industry, agriculture, and national defense. In the actual production process, chips need to go through multiple production processes such as wafer processing, packaging, and testing. Chips are precision components with small and complex structures. To facilitate detection or installation with other components, generally, before testing, packaging and other processes, the direction of the chip needs to be adjusted, that is, the chip is aligned. However, the prior art usually aligns the chip manually, which is time-consuming, laborious, costly, and inefficient, and is not conducive to subsequent chip production operations and affects production efficiency. Therefore, it is of great significance to study a device that can align chips. Summary of the Utility Model

[0003] Based on this, the purpose of the present utility model is to provide a chip alignment device.

[0004] A chip alignment device includes a base assembly, a pushing assembly, and an alignment assembly. The pushing assembly is arranged above the base assembly, and the alignment assembly is arranged on the pushing assembly. As the pushing assembly rises or falls, the alignment assembly moves closer to or farther away from each other.

[0005] Compared with the prior art, in the chip alignment device of the present utility model, the alignment assembly is arranged above the pushing assembly. As the pushing assembly rises or falls, the alignment assembly moves closer to or farther away from each other. The chip alignment device of the present utility model has a simple structure, is easy to operate, does not require manual operation, and has high efficiency.

[0006] Further, it further includes a rotating assembly. The rotating assembly is installed above the pushing assembly and drives the alignment assembly to rotate to adjust the angle of the chip relative to other devices.

[0007] Further, the pushing assembly includes a lifting motor, a motor mounting base, a jacking rod, and a cam. The motor mounting base is installed above the base assembly; the lifting motor is fixed to the motor mounting base; the cam is installed on the output shaft of the lifting motor and rotates therewith. The jacking rod extends from the cam towards the alignment assembly. One end of the jacking rod is in contact with the side surface of the cam, and the other end abuts against the alignment assembly and moves away from or closer to the alignment assembly as the cam rotates.

[0008] Further, the regularization component includes a first regularization block, a second regularization block, a first sliding block, a second sliding block, and rollers. The first sliding block and the second sliding block can slide closer to or away from each other in a direction perpendicular to the lifting direction of the pushing component. The first regularization block and the second regularization block are respectively fixed to the first sliding block and the second sliding block. The two rollers are arranged oppositely and are respectively axially connected to the first sliding block and the second sliding block. Their axes are parallel to the sliding direction of the first sliding block and perpendicular to the lifting direction of the pushing component. The wheel surfaces of the rollers are in contact with the jacking rod.

[0009] Further, the first sliding block and the second sliding block are elastically connected by a first tension spring and a second tension spring. The first tension spring and the second tension spring are respectively located on the two outer sides of the first sliding block and the second sliding block, and their axes are parallel to the sliding direction of the first sliding block. Since the tension spring is stretchable, it can meet the regularization of chips of different sizes.

[0010] Further, the rotation component includes a rotation motor, a rotation seat, a driving wheel, a driven wheel, and a driven wheel bracket. The rotation motor is installed on one side of the motor mounting seat. The driven wheel bracket is located on the other side of the motor mounting seat. The driving wheel and the driven wheel are arranged oppositely on both sides of the motor mounting seat. The driving wheel is installed on the output shaft of the rotation motor, and the driven wheel is installed on the driven wheel bracket. The rotation seat is fixed to the side of the driven wheel facing away from the cam, and the rotation seat can rotate with the rotation of the driven wheel.

[0011] Further, the regularization component further includes a regularization seat, and the regularization seat is fixedly installed on the rotation seat and can rotate with the rotation seat.

[0012] Further, the cam is an eccentric wheel, and the cam rotates eccentrically following the rotation of the lifting motor.

[0013] Further, a tapered portion is provided at one end of the jacking rod away from the cam. In the extending direction of the jacking rod, the cross-sectional area of the tapered portion on the side close to the regularization component is smaller than the cross-sectional area on the side close to the cam. This improves the smoothness of the jacking rod driving the first sliding block and the second sliding block to move away from each other.

[0014] Further, coaxial circular through holes are provided on the driven wheel and the rotation seat. After the jacking rod passes through the circular through holes of the driven wheel and the rotation seat, the tapered portion abuts against the regularization component.

[0015] For better understanding and implementation, the present invention will be described in detail below with reference to the accompanying drawings. Description of the Drawings

[0022] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0023] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0024] In this embodiment, the chip regularizing device is placed on the workbench surface. The direction perpendicular to the workbench surface is the Z direction, and the two directions parallel to and perpendicular to each other on the workbench surface are the X direction and the Y direction respectively. The workbench can be a turntable that rotates around an axis parallel to the Z direction to rotate the chip regularizing device to different stations.

[0025] Please refer to Figures 1 to 6As shown, in this embodiment, a chip rectifying device includes a base assembly 10, a pushing assembly 20, a rotating assembly 30, and a rectifying assembly 40. The base assembly 10 is horizontally placed on a table for supporting the entire chip rectifying device. The pushing assembly 20 is vertically assembled above the base assembly 10. The rotating assembly 30 is movably disposed on the pushing assembly 20. The rectifying assembly 40 is located above the rotating assembly 30. With the lifting of the pushing assembly 20 and the rotation of the rotating assembly 30, the rectifying assembly 40 can adjust the angle and rectify the chip.

[0026] Specifically, as Figure 1 shown, the base assembly 10 is a rectangular structure, and the base assembly 10 is horizontally placed on a workbench for supporting the entire device. The base assembly 10 is provided with a direction adjustment unit, including a Y-axis direction fine adjustment device 11 and an X-axis direction fine adjustment device 12, which are used to adjust the slight deviation generated during the assembly of the entire device, and can perform fine adjustment in the XY direction according to different actual incoming material conditions, so as to realize modular replacement of the device. It should be noted that the Y-axis direction fine adjustment device 11 and the X-axis direction fine adjustment device 12 in this embodiment are conventional existing designs and will not be described in detail here.

[0027] Please refer to Figure 2, The pushing component 20 is installed above the base component 10. The pushing component 20 includes a lifting motor 21, a motor mounting seat 22, a jacking rod 23, a cam 24 and a contact block 25. The motor mounting seat 22 is fixed on one side above the base component 10. The lifting motor 21 is installed on the motor mounting seat 22, and its output shaft is parallel to the workbench surface and extends towards the regularizing component 40. The cam 24 is installed on the output shaft of the lifting motor 21 and rotates therewith. The cam 24 is an eccentric wheel, and the output shaft of the lifting motor 21 passes through the center of the cam 24, so that the cam 24 rotates eccentrically following the lifting motor 21. The contact block 25 is horizontally placed above the cam 24 and abuts against the side surface of the cam 24. When the cam 24 rotates, the contact block 25 moves up and down along the Z direction; one end of the jacking rod 23 is connected to the contact block 25 and extends along the Z direction. The other end of the jacking rod 23 away from the contact block 25 is a tapered portion 231, and the cross-sectional area of the tapered portion 231 on the side away from the contact block 25 is smaller than the cross-sectional area on the side close to the contact block 25. The tapered portion 231 of the jacking rod 23 passes through the rotating component 30 and abuts against the regularizing component 40. Further, the pushing component 20 further includes a spring 26 and a sliding sleeve 27. The spring 26 is sleeved outside the jacking rod 23, and its two ends respectively abut against the contact block 25 and the sliding sleeve 27. The sliding sleeve 26 is sleeved outside the jacking rod 23, and its two ends respectively abut against the rotating component 30 and the spring 26. When the lifting motor 21 rotates, as the cam 24 rotates eccentrically therewith, the cam 24 pushes the jacking rod 23 to rise upwards. At this time, the spring 26 is in a compressed state. When the jacking rod 23 descends, the elastic force of the spring 26 is slowly released, which can prevent the jacking rod 23 from quickly descending and hitting the cam 24, and thus reciprocating lifting can be realized.

[0028] Continue to refer to Figure 3, the rotating assembly 30 is installed above the pushing assembly 20. The rotating assembly 30 includes a rotating motor 31, a rotating base 32, a driving wheel 33, a driven wheel 34, a driven wheel bracket 35 and a belt 36. The rotating motor 31 is installed on one side of the motor mounting base 22, and its output shaft axis is parallel to the Z direction. Preferably, the rotating motor 31 and the lifting motor 21 are located on the same side of the motor mounting base 22, and the rotating motor 31 is located above the lifting motor 21 to have a compact structure. The driven wheel bracket 35 is installed on the motor mounting base 22 and above the cam 24. The driven wheel 34 is pivotally connected to the driven wheel bracket 35 and can rotate about an axis parallel to the Z-axis direction. The driving wheel 33 is installed on the output shaft of the rotating motor 31. The driving wheel 33 and the driven wheel 34 are relatively arranged on both sides of the motor mounting base 22. The belt 36 is connected between the driving wheel 33 and the driven wheel 34 for transmission. When the rotating motor 31 rotates, the driving wheel 33 rotates to drive the driven wheel 34 to rotate together. The rotating base 32 is fixedly connected to the side of the driven wheel 34 facing away from the cam 24, and the rotating base 32 can rotate with the rotation of the driven wheel 34. Coaxial circular through holes (not marked) are provided on the driven wheel 34 and the rotating base 32. After the jacking rod 23 passes through the circular through holes of the driven wheel 34 and the rotating base 32, the conical portion 231 abuts against the regularizing assembly 40.

[0029] Continue to refer to Figures 4 to 6, the regularizing component 40 is installed on the rotating component 30. The regularizing component 40 includes a first regularizing block 41, a second regularizing block 42, a first sliding block 43, a second sliding block 44, a first sliding groove 45, a second sliding groove 46, a first tension spring 47, a second tension spring 48, a regularizing seat 49 and two rollers 50. The regularizing seat 49 is fixedly connected to the rotating seat 32 and can rotate together with the rotating seat 32. The first sliding block 43 and the second sliding block 44 are oppositely arranged on the side of the regularizing seat 49 facing away from the rotating seat 32 and can approach or separate from each other in a direction perpendicular to the Z direction. The first regularizing block 41 and the second regularizing block 42 are respectively fixed to the first sliding block 43 and the second sliding block 44. The chip to be regularized is placed between the first regularizing block 41 and the second regularizing block 42, and different first regularizing blocks 41 and second regularizing blocks 42 can be replaced according to the shapes of different chips to adapt to chips of different shapes. Preferably, the first regularizing block 41 and the second regularizing block 42 have opposite and parallel regularizing surfaces (not marked), and the regularizing surfaces are parallel to the Z direction to better clamp the chip. The two rollers 50 are oppositely arranged and are respectively axially connected to the first sliding block 43 and the second sliding block 44. Their axes are parallel to each other and perpendicular to the sliding direction of the first sliding block 43 and the second sliding block 44, so that the wheel surfaces of the rollers 410 are in contact with the conical part 231. When the cam 24 drives the lifting rod 23 to rise, since the conical part 231 abuts against the bottoms of the two rollers 410, the lifting rod 23 can push the two rollers 410 away from each other, so that the first regularizing block 41 and the second regularizing block 42 are separated from each other. The first sliding groove 45 and the second sliding groove 46 are oppositely arranged on the regularizing seat 49, and their extending directions are parallel to the sliding direction of the first sliding block 43 and the second sliding block 44. The first sliding block 43 and the second sliding block 44 are respectively arranged in the first sliding groove 45 and the second sliding groove 46 and slide along them. The first tension spring 47 and the second tension spring 48 are respectively connected between the first sliding block 43 and the second sliding block 44, and their axes are parallel to the sliding direction of the first sliding block 43 and the second sliding block 44. In this embodiment, when projected along the Z direction, in the direction perpendicular to the sliding direction of the first sliding groove 45 and the second sliding groove 46, the first tension spring 47 and the second tension spring 48 are respectively located on the two outer sides of the first sliding block 43 and the second sliding block 44 and are connected between the first sliding block 43 and the second sliding block 44, so as to uniformly generate a pulling force pointing to the opposite sides of the first sliding block 43 and the second sliding block 44 on the opposite sides of the first sliding block 43 and the second sliding block 44.Since the tension spring is retractable, when the lifting rod 23 descends, the first tension spring 47 and the second tension spring 48 force the guiding planes of the first alignment block 41 and the second alignment block 42 to approach each other. The guiding planes of the first alignment block 41 and the second alignment block 42 touch the side surface of the chip, so that the chip is aligned and its direction is adjusted under the action of the first alignment block 41 and the second alignment block 42.

[0030] In this embodiment, the specific operation process is as follows: when the lifting motor 21 drives the lifting rod 23 to rise, the conical portion 231 of the lifting rod 23 abuts against the bottoms of the two rollers 410, so that the two rollers 410 move away from each other. Further, the alignment surfaces of the first alignment block 41 and the second alignment block 42 move away from each other. A chip is placed between the first alignment block 41 and the second alignment block 42 through a device such as a suction nozzle or a manipulator. Then, when the lifting motor 21 stops driving the lifting rod 23 to rise and reverses to the initial state, when the lifting rod 23 descends, the first sliding block 43 and the second sliding block 44 approach each other under the action of the first tension spring 46 and the second tension spring 47, and the alignment surfaces of the first alignment block 41 and the second alignment block 42 touch the side surface of the chip, so as to clamp the chip. Then, the rotation motor 31 drives the alignment base 49 to rotate to adjust the angle of the chip relative to other devices.

[0031] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and the present invention also intends to include these modifications and improvements.
