Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chip testing, in particular to a rotary table feeding mechanism and a chip detection device. BACKGROUND

[0002] After the chip is manufactured, it needs to go through detection, sorting, packaging and other processes before it can be applied to various electronic products. When detecting the chip, a rotary table feeding device is usually used. The rotary table is connected with a carrying manipulator. Through the rotation of the rotary table, the carrying manipulator is circulated between the feeding position and the discharging position to meet the chip feeding.

[0003] In the related art, the chip is usually picked up by vacuum adsorption. However, the chip will produce a certain angle deflection in the instant of suction, which will cause an angle deviation between the chip and the corresponding position of the subsequent process, and thus cause the risk of dropping or damaging the chip.

The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0029] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , an embodiment of the present application provides a rotary table feeding mechanism, which comprises a rotary table component 10 and a plurality of pickup components 20. The rotary table component 10 at least comprises a rotary table 11 capable of rotating around its own axis, and the plurality of pickup components 20 are connected to the rotary table 11 and arranged at intervals along the circumference of the rotary table 11. The rotation of the rotary table 11 can drive the synchronous movement of each pickup component 20. In actual use, often a feeding position and a discharging position are arranged at intervals along the circumference of the rotary table 11, and the rotary table 11 drives the pickup component 20 to flow between the feeding position and the discharging position, thereby realizing the feeding of chips. Each pickup component 20 can be used to carry chips by vacuum adsorption; of course, the pickup component 20 can also use a jaw to hold and carry chips, as long as it can meet the requirements of each pickup component 20 for carrying chips.

[0030] The rotary table feeding mechanism further comprises a rotary positioning component 40, which is arranged on the outer periphery of the rotary table 11 and below each pickup component 20. The rotary positioning component 40 at least comprises a positioning group 41 surrounding a loading space 4101, and the positioning group 41 is capable of rotating around the positioning axis of the loading space 4101, and the positioning group 41 is used for clamping and positioning chips.

[0031] For example, when the pickup component 20 picks up the chip at the incoming position by vacuum adsorption, the instantaneous large negative pressure directly acts on the chip, which may cause the chip to deflect at an angle. At this time, due to the arrangement of the rotating positioning component 40, the pickup component 20 can be rotated to move to a position opposite to the rotating positioning component 40 after picking up the chip, and the positioning group 41 in the rotating positioning component 40 can be rotated according to the position of the chip after deflection to make the position of the load space 4101 on the positioning group 41 adapt to the chip on the pickup component 20. The pickup component 20 adsorbs the chip and places it in the load space 4101, and is clamped and positioned by the positioning group 41. In this process, the pickup component 20 does not release the vacuum, that is, the pickup component 20 still has a vacuum adsorption effect on the chip. Then, the positioning group 41 is reversely rotated around the positioning axis, and the chip is synchronously rotated to change the angle of the chip relative to the pickup component 20. At the same time, since the pickup component 20 has a vacuum adsorption effect on the chip, it does not affect the mechanical positioning and rotation of the positioning group 41 on the chip. In this way, the deflection angle of the chip during adsorption can be adjusted and compensated, which is beneficial to the chip alignment, thereby reducing the angle deviation of the chip and the corresponding position of the subsequent process, and relieving the risk of dropping or damage.

[0032] Please refer to Figure 1 and Figure 3 In actual use, the turntable feeding mechanism further includes a visual detection component 30, which is arranged on the outer circumferential side of the turntable 11 and is spaced apart from the rotating positioning component 40 along the circumferential direction of the turntable 11, and is located below each pickup component 20. The visual detection component 30 is used to obtain displacement image information of the pickup component 20 picking up the chip, and the positioning group 41 is configured to rotate around the positioning axis in response to the pose image information of the visual detection component 30.

[0033] That is, after the pickup component 20 picks up the chip, it can be first rotated to the upper side of the visual detection component 30 under the action of the turntable 11, and a photo is taken by the visual detection component 30 to obtain the pose image information of the chip relative to the pickup component 20, that is, the deflection angle. Then, the positioning group 41 can be reversely rotated around the positioning axis according to the corresponding deflection angle to align the load space 4101 with the chip, which is beneficial to the clamping of the positioning group 41 on the chip. After the positioning group 41 clamps the chip, the positioning group 41 can be reversely rotated to align the chip relative to the pickup component 20 and compensate the deflection angle. The visual detection component 30 can be a camera module.

[0034] Alternatively, the position coordinates of multiple points on the chip can be obtained by laser detection, and then the corresponding deflection angle can be calculated, which is beneficial to the adjustment of the positioning group 41.

[0035] Further, the rotary disc 11 has a feeding rotation direction when feeding. For example, the clockwise rotation of the rotary disc 11 is the feeding rotation direction. The visual detection component 30 is located upstream of the rotary positioning component 40 along the feeding rotation direction. That is, when the rotary disc 11 drives the pickup component 20 to rotate for feeding, the pickup component 20 sequentially passes through the visual detection component 30 and the rotary positioning component 40, that is, first passes through the visual detection component 30 to obtain the pose image information of the chip, then passes through the rotary positioning component 40 for angle compensation, and finally moves to the unloading position to realize the feeding of the chip. Such a configuration is more in line with the feeding rhythm of the rotary disc 11, and the angle compensation can be completed in the feeding path, thereby improving the feeding efficiency.

[0036] Alternatively, the visual detection component 30 can be located downstream of the rotary positioning component 40 along the feeding rotation direction. In this case, the rotary disc 11 needs to first move to the visual detection component 30 by passing through the rotary positioning component 40, then reversely rotate to the rotary positioning component 40 for compensation, and then rotate to the unloading position along the feeding rotation direction.

[0037] Please refer to Figure 1 , Figure 4 and Figure 5 , as some embodiments, the positioning group 41 includes a jaw seat 411 and a plurality of jaws 412 arranged circumferentially along the jaw seat 411 and rotationally connected to the jaw seat 411. The plurality of jaws 412 cooperates to collectively surround the loading space 4101, and realizes clamping of the chip. The positioning group 41 further includes a bearing boss 414 arranged in the middle of the jaw seat 411. The bearing boss 414 is upwardly protruded along the Z-axis direction to substantially match the size of the chip, so as to reduce the interference when each jaw 412 clamps. In some specific embodiments, the jaw 412 is provided with four, and the end of each jaw 412 is linear to match the four edges of the chip and realize clamping.

[0038] Further, the rotary positioning component 40 further includes a support shaft 42 and a lifting shaft 43 slidingly connected to the support shaft 42. The support shaft 42 is connected with the jaw seat 411, and the support shaft 42 can rotate around its own axis to drive the positioning group 41 to synchronously rotate. The lifting shaft 43 can move along the axial direction of the support shaft 42 to drive each jaw 412 to rotate. In actual use, the support shaft 42 is connected with a rotary motor 46 to drive the support shaft 42 to rotate. The axial direction of the support shaft 42 is along the Z-axis direction. The lifting shaft 43 is connected with a lifting motor 45 to drive the lifting shaft 43 to move along the Z-axis direction, thereby driving each jaw 412 to rotate relative to the jaw seat 411 to realize clamping and positioning of the chip.

[0039] The lifting shaft 43 is sleeved outside the supporting shaft 42, and a linear bearing is arranged between the lifting shaft 43 and the supporting shaft 42, which is beneficial to the axial movement of the lifting shaft 43 relative to the supporting shaft 42 and plays a guiding role. The clamping jaw seat 411 is provided with a plurality of avoiding grooves, and each avoiding groove is correspondingly provided with a clamping jaw 412. The lifting shaft 43 moves upward along the Z-axis to drive each clamping jaw 412 to rotate outward relative to the clamping jaw seat 411 to be opened, which is beneficial to placing the chip in the loading space 4101 and supporting on the bearing boss 414. Meanwhile, each clamping jaw 412 is correspondingly provided with an elastic member, and each elastic member is pre-pressed between the corresponding clamping jaw 412 and the clamping jaw seat 411 and is arranged in the corresponding avoiding groove. Each clamping jaw 412 has a movement trend of rotating inward to clamp under the action of the corresponding elastic member.

[0040] As shown in Figure 5 Further, the clamping jaw seat 411 is provided with a plurality of jacking channels 4110 arranged along the circumferential direction, and the lifting shaft 43 is provided with a plurality of top contact portions 432 arranged along the axis of the lifting shaft 43. Each top contact portion 432 is correspondingly arranged in a jacking channel 4110 and corresponds to a clamping jaw 412. When the lifting shaft 43 moves along the Z-axis direction under the action of an external force, each top contact portion 432 moves in the corresponding jacking channel 4110 to act on the corresponding clamping jaw 412, thereby achieving the rotation driving of the clamping jaw 412. Such a design is beneficial to reducing the diameter of the lifting shaft 43, thereby reducing the planar size of the whole rotating positioning component 40 and reducing the assembly interference with other structures in the rotary table feeding mechanism.

[0041] Each top contact portion 432 is provided with a conical surface on the side away from the positioning axis. Each clamping jaw 412 is correspondingly provided with a roller 413 to cooperate with the corresponding conical surface, thereby reducing the wear.

[0042] Optionally, the rotating positioning component 40 further comprises a driving shaft 44, which is movably connected with the lifting shaft 43 and is used to drive the lifting shaft 43 to move along the axis of the supporting shaft 42. The driving shaft 44 is connected between the lifting shaft 43 and the lifting motor 45. Of course, a cylinder can also be used to drive the lifting shaft 43 to move along the Z-axis through the driving shaft 44, thereby achieving the rotation driving of the clamping jaw 412.

[0043] As shown in Figure 4 and Figure 5As shown, further, the drive shaft 44 comprises a connecting portion 441 and a cooperating portion 442, the cooperating portion 442 is connected with the connecting portion 441 and is eccentrically arranged, and the cooperating portion 442 is movably connected with the lifting shaft 43. The connecting portion 441 can rotate around its own axis to drive the lifting shaft 43 to move along the axial direction of the supporting shaft 42 through the cooperating portion 442. The axis of the connecting portion 441 is arranged at an angle with the axis of the supporting shaft 42. For example, the axis of the connecting portion 441 is along the X-axis direction. That is to say, the connecting portion 441 and the cooperating portion 442 jointly form an eccentric wheel structure, when the connecting portion 441 rotates around its own axis, the position of the cooperating portion 442 along the Z-axis direction changes, thereby driving the lifting shaft 43 to ascend and descend along the Z-axis direction.

[0044] Further, the outer circumferential surface of the lifting shaft 43 is concavely provided with an assembly groove 431, the assembly groove 431 is annularly arranged on the lifting shaft 43, and the cooperating portion 442 of the drive shaft 44 is inserted into the assembly groove 431 and can move in the assembly groove 431. That is to say, the assembly groove 431 is arranged to realize the movable cooperation and power transmission between the lifting shaft 43 and the drive shaft 44. Such an arrangement can ensure the freedom between the lifting shaft 43 and the drive shaft 44, avoiding the problem of being stuck; on the other hand, it can ensure that the cooperating portion 442 of the lifting shaft 43 and the drive shaft 44 is in full contact, and has a force applying position on both sides along the Z-axis direction, which is beneficial to driving the lifting shaft 43 to ascend and descend.

[0045] Among them, the cooperating portion 442 comprises a shaft body and a first roller, the shaft body is connected to the connecting portion 441, and the first roller is rotatably connected to the shaft body, and the first roller is in rolling cooperation with the groove wall of the assembly groove 431. That is to say, by using the rolling cooperation of the first roller, the wear between the lifting shaft 43 and the cooperating portion 442 is reduced, and the freedom of the cooperation between the two is further increased.

[0046] As shown in Figure 1 , Figure 4 and Figure 5 , in actual use, the rotary positioning component 40 further comprises an assembly support 47, the clamping jaw seat 411 is rotatably mounted on the assembly support 47, and the aforementioned lifting motor 45, drive shaft 44, rotary motor 46 and the like are all mounted on the assembly support 47. The assembly support 47 is used to integrate and assemble the various structures in the rotary positioning component 40 into a whole structure, which is beneficial to assembly and disassembly as a whole. Among them, the rotary positioning component 40 is assembled on the mounting base plate 90 through the assembly support 47.

[0047] Please refer to Figures 1 to 3In an optional embodiment, the rotary table feeding mechanism further comprises a feeding component 60 and a detection component 70, both of which are arranged at the outer circumferential side of the rotary table 11, and the feeding component 60, the detection component 70, the visual detection component 30 and the rotary positioning component 40 are all arranged at intervals along the circumference of the rotary table 11, and the detection component 70 is arranged between the feeding component 60 and the visual detection component 30, and the visual detection component 30 is arranged between the detection component 70 and the rotary positioning component 40. The feeding component 60 is used to provide the chips to be tested, the pickup component 20 picks up the chips at the feeding component 60 and moves to the detection component 70 under the action of the rotary table 11, and the relevant parameters are tested through the detection component 70. After testing, the chip is moved to the visual detection component 30 through the cooperation of the pickup component 20 and the rotary table 11 for shooting, and then moved to the rotary positioning component 40 for deflection angle adjustment. After the chip is aligned relative to the pickup component 20, the pickup component 20 and the rotary table 11 cooperate to move the chip to the unloading position, thereby facilitating the next process to take over for other tests.

[0048] The detection component 70 comprises a polarity testing structure 73 and a visual image collector 72, both of which are arranged at intervals along the circumference of the rotary table 11, and the polarity testing structure 73 is located between the visual image collector 72 and the feeding component 60. The polarity testing structure 73 is used to detect the electrical properties of the chip pins, and is used to determine whether the circuit placement is reversed, misaligned, etc. The visual image collector 72 detects whether the chip pins have defects through shooting. The detection component 70 further comprises a rotary support table 71, which is located below the visual image collector 72 and is used to support the chip. In actual operation, the pickup component 20 carries the chip to the polarity testing structure 73, performs polarity testing, carries the chip to the rotary support table 71 and places it on the rotary support table 71, the rotary support table 71 drives the chip to rotate to a position opposite the visual image collector 72, the visual image collector 72 performs shooting and collection, and then the rotary support table 71 drives the chip to rotate to a position opposite the pickup component 20, which facilitates the pickup component 20 to pick up the chip again and carry it to the visual detection component 30 for deflection angle detection.

[0049] Please continue to refer to Figures 1 to 3Further, the rotary table feeding mechanism further comprises a gripper positioning component 80, which is arranged along the circumference of the rotary table 11 and is spaced apart from the incoming material component 60, the detection component 70, the visual detection component 30 and the rotary positioning component 40, and is located between the detection component 70 and the incoming material component 60. That is, by arranging the gripper positioning component 80, the pose of the chip provided by the incoming material component 60 can be corrected, so as to facilitate the alignment detection of the subsequent detection component 70 and ensure a certain detection precision. The specific structure of the gripper positioning component 80 is basically similar to that of the rotary positioning component 40, and the difference lies in that the gripper positioning component 80 does not need to rotate, and therefore the rotary motor 46 does not need to be arranged. The aforementioned support shaft 42 can be installed on the assembly support 47 to guide the movement of the lifting shaft 43 along the Z-axis direction.

[0050] Further, the incoming material component 60 comprises a hopper 61, a vibrating disc 62, a vibrating straight rail 63 and a particle separation assembly 64. The outlet of the hopper 61 is connected to the inlet of the vibrating disc 62, the outlet of the vibrating disc 62 is connected to the input end of the vibrating straight rail 63, and the particle separation assembly 64 is arranged at the output end of the vibrating straight rail 63. The output end of the vibrating straight rail 63 is arranged close to and below the pickup component 20, so as to facilitate the pickup component 20 to pick up the chip from the output end of the vibrating straight rail 63 for feeding.

[0051] In actual use, the chip is loaded in the hopper 61 and fed to the vibrating disc 62 through vibration. The vibrating disc 62 can drive the chip to enter the vibrating straight rail 63 in an orderly manner through vibration, and the chip is sequentially transported towards the output end through the vibration of the vibrating straight rail 63. The vibrating straight rail 63 is provided with a rail material receiving position and a material taking position, and the material taking position is located downstream of the rail material receiving position. The material taking position is used for adsorbing and taking material by the pickup component 20. The vibrating straight rail 63 is provided with a vacuum adsorption hole for positioning the chip. When the vibrating straight rail 63 is used for feeding, the vacuum adsorption hole at the bottom of the first chip on the vibrating straight rail 63 is released, and the next three chips are fixed by vacuum adsorption. The particle separation assembly 64 drives the first chip to the material taking position. After the pickup component 20 picks up the chip at the material taking position, the particle separation assembly 64 moves to the rail material receiving position and drives the first chip at this moment to the material taking position. In this way, the feeding of single chips is realized in a reciprocating cycle.

[0052] The specific structures of the hopper 61, the vibrating disc 62, the vibrating straight rail 63 and the particle separation assembly 64 are existing mature technologies and do not belong to the application points of the present application, so they will not be described here.

[0053] Please continue to refer to Figures 1 to 3In some embodiments, each pickup component 20 comprises an assembly seat and a pickup piece movably connected to the assembly seat, the assembly seat is connected to the turntable 11 to realize the assembly of each pickup component 20 relative to the turntable 11. The turntable 11 can be provided with a plurality of support arms along the radial direction thereof, the plurality of support arms are arranged in a radial manner along the circumference of the turntable 11, and the ends of at least part of the support arms are connected to a pickup component 20.

[0054] Further, the turntable feeding mechanism further comprises a plurality of pressing components 50, each of which is connected to the turntable 11 and arranged in a circumferential direction of the turntable 11, each pressing component 50 corresponds to a pickup component 20 and is used to drive the corresponding pickup piece to move in the vertical direction (i.e. the Z-axis direction). That is, the pickup piece can be slidably connected to the assembly seat, facilitating reciprocating motion in the Z-axis direction. The pressing component 50 can be driven by an electric push rod or a pneumatic cylinder, as long as it can realize linear driving of the pickup piece. The turntable component 10 further comprises a support disc 12 provided on the turntable 11, which is arranged in a vertical direction above the turntable 11. The pressing component 50 comprises a pressing seat, a driving source connected to the pressing seat, and a pressing head connected to the driving source. The pressing seat is connected to the support disc 12, so that the pressing component 50 is located above the pickup component 20.

A guide rod is further provided between each pickup piece and the corresponding assembly seat to guide the movement of the pickup piece. The pickup piece needs to be driven by the pressing component 50 to move in the vertical direction when taking and placing the material.

[0055] The turntable component 10 further comprises a rotary gas circuit 13 provided on the turntable 11, which is used for rotary gas supply and vacuum adsorption of each pickup component 20, and is more suitable for rotation of each pickup component 20 with the turntable 11, avoiding gas pipe knotting, winding, etc., even pulling, damage, etc., improving the safety and reliability of use. At the same time, the turntable component 10 further comprises a rotary power source 14 connected with the turntable 11 to drive the turntable 11 to rotate. The rotary power source 14 is installed on the installation base plate.

[0056] That is, in this embodiment, the rotary power source 14 only drives the turntable 11 to rotate, and then the setting of the pressing component 50 is used to realize the movement of the pickup piece in the vertical direction in the single pickup component 20, which is conducive to taking and placing the chip. Compared with directly using the cam to drive the turntable 11 to rotate, such a setting improves the protection of the chip and reduces the indentation on the surface of the chip.

[0057] An embodiment of the present application further provides a chip detection device, which comprises a testing mechanism, a discharging mechanism and the above-mentioned turntable feeding mechanism. The testing mechanism is arranged between the turntable feeding mechanism and the discharging mechanism, and is used for testing the chips, such as performance testing at normal temperature and high temperature. The chips to be tested are transmitted to the testing mechanism through the turntable feeding mechanism, and the chips that have completed testing are transferred to the discharging mechanism for material collection. The chip detection device further comprises a transfer shuttle, which is arranged between the turntable feeding mechanism and the testing mechanism. The chips in the turntable feeding mechanism are placed on the tray of the transfer shuttle one by one, and after the tray is full, the transfer shuttle drives the tray to move to the testing mechanism to test the plurality of chips in the tray. In this process, it is just because the rotation positioning component is arranged in the turntable feeding mechanism that the deflection angle of the chip can be adjusted, the alignment accuracy of the chip and the pit position on the tray in the transfer shuttle is improved, and then the alignment accuracy between the testing mechanism and each testing head is improved.
