Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of semiconductor chip detection, and in particular to a chip positioning loading disc and a chip automatic overturning device. BACKGROUND

[0002] In the post-process of semiconductor manufacturing, multi-surface testing and inspection of chips are often required. This requires stable clamping and accurate overturning of the chips.

[0003] In the prior art, the chips are generally placed in a tray. If the gap between the tray groove and the chip is too large, the position of the chip may be offset during the detection process, resulting in errors in the detection results and reducing the detection accuracy. Therefore, when the chip is placed in the tray groove, the tray needs to fix the chip for one-side detection, and then overturn the tray for the other-side detection of the chip.

[0004] The tray includes an upper tray and a lower tray that is butted and clamped with the upper tray. The chip is first embedded in the upper tray for front surface detection of the chip. After the front surface detection of the chip is completed, the upper tray and the lower tray are butted and clamped, and then the tray is overturned as a whole, so that the chip can fall into the lower tray from the upper tray for back surface detection of the chip.

[0005] However, since the chip is embedded in the upper tray for front surface detection of the chip to ensure detection accuracy, the chip cannot fall into the lower tray under its own gravity after the tray is overturned as a whole. Therefore, the chip embedded in the upper tray needs to be manually poked one by one to make the chip fall into the lower tray. The overturning process is relatively complex and time-consuming, which reduces the overturning efficiency. At the same time, manual poking of the chip may cause damage to the chip. SUMMARY

[0011] In one of the embodiments, the abutting member has a transition portion configured to contact the stop member to prevent the stop member from deforming; the transition portion is inclined from a side close to the stop member to a side away from the stop member.

[0015] The present application further provides a chip automatic turnover device, comprising: a chip positioning and loading disc adapted to clamp a chip; a placing table for placing the chip positioning and loading disc so that the chip can be placed in a placing space of the chip positioning and loading disc; a mechanical arm arranged on one side of the placing table and interfacing with the chip positioning and loading disc to turn over the chip positioning and loading disc; In one of the embodiments, the chip positioning and loading disc is the chip positioning and loading disc as described above.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Embodiment 1: With reference to Figures 1-6 In a preferred embodiment of the present application, a chip positioning loading disc 100 is suitable for clamping a target object and turning over under the action of an external force, so as to improve detection efficiency and accuracy. In the present embodiment, the target object is a chip.

[0021] Specifically, the chip positioning loading disc 100 comprises a frame 5, a plurality of first clamping mechanisms 1 and a plurality of second clamping mechanisms 2. The frame 5 has a hollow part 51, and the plurality of first clamping mechanisms 1 and the plurality of second clamping mechanisms 2 are arranged in the hollow part 51. In the present embodiment, the material of the frame 5 is plastic. In other embodiments, the material of the frame 5 can also be metal, such as aluminum and its alloy, stainless steel, etc., which provides support force for the first clamping mechanism 1 and the second clamping mechanism 2, which is not specifically limited here.

[0022] Among them, the plurality of first clamping mechanisms 1 are arranged in the hollow part 51 along a first direction (indicated by arrow a in the figure), and the plurality of second clamping mechanisms 2 are arranged in the hollow part 51 along a second direction (indicated by arrow b in the figure), and the first direction and the second direction have an included angle, so that the plurality of first clamping mechanisms 1 and the plurality of second clamping mechanisms 2 form a plurality of placement spaces 6 for placing the target object.

[0023] The material of the plurality of first clamping mechanisms 1 and the plurality of second clamping mechanisms 2 can be soft plastic, which is relatively soft and will not cause damage to the target object due to internal stress after clamping the target object. Further, a flexible piece 8 can also be provided on the first clamping mechanism 1 and the second clamping mechanism 2 to further avoid damage to the target object.

[0024] Alternatively, the material of the plurality of first clamping mechanisms 1 and the plurality of second clamping mechanisms 2 can be metal, such as aluminum and its alloys, stainless steel, etc. At this time, the first clamping mechanism 1 and the second clamping mechanism 2 are further provided with a flexible piece 8, which can slow down the clamping force of the first clamping mechanism 1 and the second clamping mechanism 2, thereby avoiding damage to the target object.

[0025] In the embodiment, the included angle between the first direction and the second direction is 90°. That is, the first direction and the second direction are arranged vertically. At this time, taking the first direction as an example, one second clamping mechanism 2 distributed along the second direction and a plurality of first clamping mechanisms 1 distributed along the first direction form a plurality of placement spaces 6; similarly, taking the second direction as an example, one first clamping mechanism 1 distributed along the first direction and a plurality of second clamping mechanisms 2 distributed along the second direction form a plurality of placement spaces 6. As can be seen from the above arrangement, the plurality of first clamping mechanisms 1 distributed along the first direction and the plurality of second clamping mechanisms 2 distributed along the second direction can cross to form a plurality of placement spaces 6, so that one chip positioning loading disc 100 can place a plurality of chips to clamp and fix the plurality of chips, thereby improving the detection efficiency of the chips.

[0026] In other embodiments, the included angle between the first direction and the second direction can also be 45°, 60°, etc., which is not limited here and can be determined according to the shape of the target object.

[0027] Each first clamping mechanism 1 includes a fixed piece 12 fixedly connected with the frame 5 and a first clamping piece 11 arranged opposite to the fixed piece 12, and the first clamping piece 11 can move relative to the fixed piece 12 under the action of an external force. The external force can be artificial driving force.

[0028] That is, the first clamping piece 11 can be driven by human to move relative to the fixed piece 12 to adjust the size of the placement space 6 along the second direction.

[0029] Alternatively, the external force is a mechanical force. At this time, the chip positioning loading disc 100 further includes a driving mechanism 3, and the driving mechanism 3 includes a first driving assembly 31 connected with the first clamping piece 11. The first driving assembly 31 is connected with the first clamping piece 11 to drive the first clamping piece 11 to move relative to the fixed piece 12 along the second direction.

[0030] Specifically, the first driving assembly 31 includes a first driving piece 311, a first transmission piece connected with the first driving piece 311, and a first rotating shaft 312 threadedly connected with the first transmission piece. The first driving piece 311 drives the first transmission piece to rotate, and the first transmission piece remains in position. Since the first rotating shaft 312 is threadedly connected with the first transmission piece, the thread converts the rotary motion into linear motion, so that the first rotating shaft 312 can move relative to the first driving piece 311 along the second direction.

[0031] In the embodiment, the first driving member 311 is a driving motor, the first transmission member includes a first gear connected with the first driving member 311 and a second gear engaged with the first gear, and the first rotating shaft 312 is threadedly connected with the second gear.

[0032] In order to facilitate the arrangement of the first driving member 311, the first driving member 311 is arranged outside the frame 5, and the first rotating shaft 312 passes through the frame 5 to be connected with the plurality of first clamping members 11.

[0033] In the embodiment, two first driving assemblies 31 are arranged, and the two first driving assemblies 31 are arranged on the two sides of the frame 5 along the first direction, respectively. The two first rotating shafts 312 are fixedly connected with the two sides of the first clamping member 11 to drive the first clamping member 11 to move.

[0034] However, in the process of driving the first clamping member 11 to move by the first driving assembly 31, since the two side portions of the first clamping member 11 are driven by mechanical force, and the middle portion of the first clamping member 11 is not subjected to force and moves along with the two side portions of the first clamping member 11, the middle portion of the first clamping member 11 is subjected to uneven force with the two side portions of the first clamping member 11, and the first clamping member 11 is curved. The problem caused by this is that when the two side portions of the first clamping member 11 have contacted the chip in the corresponding placement space 6, the middle portion of the first clamping member 11 still has a spacing with the chip in the corresponding placement space 6. When the first clamping member 11 continues to move towards the fixing member 12, so that the middle portion of the first clamping member 11 contacts the chip in the corresponding placement space 6, the two side portions of the first clamping member 11 have been over-matched with the chip in the corresponding placement space 6, thereby causing the chip in this portion to be damaged under the action of the clamping force.

[0035] In order to prevent the above-mentioned phenomenon from occurring, the chip positioning and loading disc 100 in the embodiment further includes a plurality of stop block mechanisms 4 arranged in the first direction in the hollow part 51. Each stop block mechanism 4 is arranged close to the edge of the frame 5 and between the first clamping member 11 and the fixing member 12. That is, each stop block mechanism 4 abuts against the two side portions of the first clamping member 11.

[0036] The two side portions of the first clamping member 11 are defined as abutting portions 111, and when the first clamping member 11 moves to the stop block mechanism 4, the abutting portions 111 abut against the stop block mechanism 4 to prevent the abutting portions 111 from continuing to move towards the fixing member 12. As known from the foregoing, the two first rotating shafts 312 are fixedly connected with the two sides of the first clamping member 11, and therefore, in order to simplify the overall structure, the first rotating shaft 312 passes through the abutting portions 111 of the plurality of first clamping members 11 and is fixedly connected with the abutting portions 111.

[0037] In order to enable the middle position part of the first clamping member 11 to continue moving towards the fixing member 12 when the abutting part 111 abuts against the stop block mechanism 4, so as to clamp the chip in the placement space 6 corresponding thereto, each first clamping member 11 further comprises a damping member 13 connected with the abutting part 111. In the embodiment, the damping member 13 is a nut connected with the first rotating shaft 312. The nut cannot continue moving towards the fixing mechanism under the blocking of the stop block mechanism 4, but since the first rotating shaft 312 as a whole still rotates, the nut can remain stationary relative to the first rotating shaft 312 and does not hinder the movement of the first rotating shaft 312, thereby ensuring that the middle position part of the first clamping member 11 can still move towards the fixing member 12.

[0038] Each stop block mechanism 4 comprises a first stop block 41 and an abutting assembly abutting against the first stop block 41, the abutting assembly being configured to be able to apply an abutting force to the first stop block 41, so as to enable the first clamping member 11 to abut against the first stop block 41. The purpose of such arrangement is to prevent the first stop block 41 from tilting towards the fixing member 12 under the drive of mechanical force, thereby causing damage to the chips in the placement spaces 6 on both sides.

[0039] The abutting assembly comprises a second stop block 42 oppositely arranged with the first stop block 41, and an elastic member 43 arranged between the first stop block 41 and the second stop block 42, the elastic member 43 always applies a biasing force to the first stop block 41.

[0040] Furthermore, in order to ensure that the biasing force of the elastic member 43 does not deviate and weaken, the abutting assembly further comprises a guide member and a baffle plate 44 penetrating through the first stop block 41 and the second stop block 42 and fixedly connected with the first clamping member 11; the elastic member 43 is arranged on the guide member, and the baffle plate 44 is connected with the elastic member 43 and abuts against the first stop block 41. In the embodiment, the guide member is a guide column.

[0041] A plurality of second clamping mechanisms 2 are arranged in the hollow part 51 along the second direction. Each second clamping mechanism 2 comprises a stop member 22 connected with the fixing member 12 and a second clamping member 21 oppositely arranged with the stop member 22, the second clamping member 21 being movable relative to the stop member 22 under the drive of external force. The one end of each stop member 22 is fixedly connected with the fixing member 12. Compared with the first clamping mechanism 1, the purpose of the second clamping mechanism 2 is mainly to provide smaller force to enable the chip in the placement space 6 to align with the stop member 22, so as to determine the position of the chip.

[0042] Since the first clamping mechanism 1 and the second clamping mechanism 2 can form the placement space 6, in the embodiment, the second clamping member 21 has an avoiding groove 211 adapted for the first clamping member 11 and the fixing member 12 to penetrate through, so as to avoid hindering the movement of the first clamping member 11.

[0043] Therefore, the external force driving of the second clamping member 21 described above can be driven by human, so as to be moved relative to the stop member 22 to adjust the size of the placing space 6 along the first direction.

[0044] Alternatively, the external force is a mechanical force. Correspondingly, the driving mechanism 3 further comprises a second driving assembly 32 connected with the second clamping member 21 to drive the second clamping member 21 to move along the second direction. The second driving assembly 32 is provided with two, and the two second driving assemblies 32 are respectively arranged on both sides of the frame 5 along the second direction, and the two second rotating shafts 322 are fixedly connected with the two sides of the second clamping member 21 to drive the second clamping member 21 to move.

[0045] The second driving assembly 32 comprises a second driving member 321, a second transmission member connected with the second driving member 321, and a second rotating shaft 322 threadedly connected with the second transmission member, and the second rotating shaft 322 penetrates through the plurality of second clamping members 21 and is fixedly connected with the second clamping members 21. The second driving member 321 drives the second transmission member to rotate, and the second transmission member remains in position. Since the second rotating shaft 322 is threadedly connected with the second transmission member, the thread converts the rotary motion into linear motion, so that the second rotating shaft 322 can move along the first direction relative to the second driving member 321.

[0046] Similarly, in the embodiment, the second driving member 321 is a driving motor, the second transmission member comprises a third gear connected with the second driving member 321 and a fourth gear meshing with the third gear, and the second rotating shaft 322 is threadedly connected with the fourth gear.

[0047] As known from the foregoing, one end of the stop member 22 is fixedly connected with the fixed member 12, and therefore, in order to avoid the stop member 22 being deformed due to extrusion of the chip during alignment with the stop member 22, each second clamping mechanism 2 further comprises an abutting member 23 connected with the first clamping member 11, and the abutting member 23 extends along the first direction. The abutting member 23 is configured to abut against the stop member 22 to prevent the stop member 22 from being deformed.

[0048] Specifically, the abutting member 23 has a transition portion which is inclined from the side close to the stop member 22 to the side away from the stop member 22. When the abutting member 23 moves towards the stop member 22 along with the first clamping member 11 until it contacts the stop member 22, the force between the stop member 22 and the abutting member 23 gradually increases under the action of the transition portion, so as to force the stop member 22 to bend towards the side close to the chip to offset the force applied to the stop member 22 by the chip during alignment with the stop member 22, thereby preventing the stop member 22 from being deformed to keep its original state and improving the accuracy of the position of the chip after clamping.

[0049] The chip positioning loading disc 100 further comprises a support base 7 connected with the frame 5, which is arranged on one side of the frame 5 and can be used to install control circuits, power supplies, switches and other components to control the opening and closing and movement of the driving mechanism 3.

[0050] The chip automatic turnover device further comprises a placing table 200 and a mechanical arm 300. The chip positioning loading disc 100 is suitable for clamping the target object. The placing table 200 is used for placing the chip positioning loading disc 100, so that the target object can be placed in the placing space 6 of the chip positioning loading disc 100. The mechanical arm 300 is arranged on one side of the placing table 200 and is opposite to the chip positioning loading disc 100, so as to turn over the chip positioning loading disc 100.

[0051] The implementation process of the chip automatic turnover device in the embodiment is as follows: the chip positioning loading disc 100 is placed on the placing table 200, and then the chip is placed in each placing space 6 of the chip positioning loading disc 100. Due to the existence of the placing table 200, the chip is prevented from falling. Then the driving mechanism 3 drives the first clamping member 11 and the second clamping member 21 to move, so that the placing space 6 gradually shrinks until the chip is clamped. The mechanical arm 300 can turn over the chip positioning loading disc 100 as a whole after detecting one side of the chip, so that the other side of the chip can be detected.

[0052] In summary, the frame 5 with the hollow part 51, the first clamping mechanism 1 and the second clamping mechanism 2 arranged in the hollow part 51 are arranged. The first clamping mechanism 1 is arranged along the first direction, the second clamping mechanism 2 is arranged along the second direction, and the first direction and the second direction are clamped, so that the first clamping mechanism 1 and the second clamping mechanism 2 can form the placing space 6 for placing the target object. The first clamping mechanism 1 comprises the fixed member 12 and the first clamping member 11, and the first clamping member 11 can move relative to the fixed member 12 under the action of external force. The second clamping mechanism 2 comprises the stop member 22 and the second clamping member 21, and the second clamping member 21 can move relative to the stop member 22 under the action of external force, so as to adjust the size of the placing space 6. When the chip is placed, it is not necessary to be accurately placed. The chip can gradually abut against the fixed member 12 and the stop member 22 under the movement of the first clamping member 11 and the second clamping member 21, and finally the chip is clamped in the placing space 6, so as to facilitate subsequent detection of the chip. After the detection of one side of the chip is completed, the chip positioning loading disc 100 can be turned over under the driving of the mechanical arm, so that the other side of the chip can be directly detected, which is convenient and fast, improves the detection efficiency and ensures the detection accuracy.
