Description

Technical Field

[0001] The present application relates to the technical field of chip testing, and particularly to a tray positioning device and a chip testing and sorting machine. Background Art

[0002] After chips are produced, they usually need to be tested and sorted. According to the test and sorting results, the chips are divided into different category levels and stored in different trays. A tray is a carrier for holding chips. A manipulator picks and places chips on the tray. Since the manipulator has relatively high requirements for the position accuracy of the chips during picking and placing, there is a need for accurate positioning of the tray.

[0003] In the prior art, a tray is usually used to hold the tray and lift it to a set position to realize the loading of the tray, and the tray is positioned on a reference plane by laterally pushing the tray in two intersecting directions. For example, in a prior art, a cylinder is used to drive a top block to move to laterally push the tray; however, driving by a cylinder requires adding solenoid valve sensors and other components for control, resulting in a large number of components and increased control difficulty. Another example of the prior art is that a top block under the force of an elastic member slides along a biaxial direction to realize the lateral pushing of the tray; however, when the force on the top block at the biaxial position is uneven, for example, when the force on the top block is not parallel to the biaxial direction, the movement of the top block will be stuck, resulting in vibration or even jamming of the tray during rising and falling, affecting the normal loading of the tray.

[0004] In view of this, it is necessary to propose a new technical solution to overcome the deficiencies of the prior art. Summary of the Utility Model

[0005] Based on this, the present application provides a tray positioning device and a chip testing and sorting machine, in which the pushing mechanism has uniform force, smooth movement, is not easily stuck, and can provide reliable and accurate positioning for the tray.

[0006] To this end, the present application adopts the following technical solution: A tray positioning device includes a tray mechanism supporting a tray, and a pushing mechanism that can apply a force to the tray during the loading movement of the tray mechanism to position the tray to a reference position. The pushing mechanism includes a mounting seat, a pushing member movably mounted on the mounting seat, and an elastic force applying member disposed between the mounting seat and the pushing member. The pushing member is hinged to the mounting seat and can swing relative to the mounting seat. Among them, the pushing member can overcome the elastic force of the elastic force applying member when being pushed and squeezed by the tray, and rotate away from the loading movement path of the tray mechanism, and when not being pushed and squeezed, rotate close to the loading movement path of the tray mechanism under the elastic force of the elastic force applying member.

[0007] In one embodiment, the pushing member includes a swing arm and a roller pivotally connected to the swing arm. One end of the swing arm is connected to the mounting base through a pivot shaft. The roller is mounted on the end of the swing arm away from the pivot shaft. The roller protrudes partially from the swing arm and can abut against the tray mechanism.

[0008] In one embodiment, the end of the swing arm provided with the pivot shaft abuts against the mounting base under the action of the elastic biasing member to define the maximum position where the pushing member rotates and protrudes toward the side of the loading movement path close to the tray mechanism.

[0009] In one embodiment, the elastic biasing member is arranged to be slidable relative to the swing arm or the mounting base;

[0010] Alternatively, the swing arm is provided with a mounting groove for receiving one end of the elastic biasing member. The mounting groove is a long strip-shaped groove to allow one end of the elastic biasing member to slide in the mounting groove when the swing arm swings relative to the mounting base.

[0011] In one embodiment, the tray mechanism includes a tray body and a chuck assembly cooperating with the pushing mechanism. The chuck assembly includes a fixed seat fixed to the tray body, a sliding member slidable relative to the fixed seat, and an elastic member disposed between the fixed seat and the sliding member. The pushing member applies a force to the tray through the sliding member, and the sliding member is squeezed by the pushing member and slides by overcoming the elastic force of the elastic member.

[0012] In one embodiment, the elastic force of the elastic biasing member is greater than the elastic force of the elastic member.

[0013] In one embodiment, the pushing mechanism and the tray mechanism have a first contact state and a second contact state; wherein,

[0014] The first contact state is: the pushing member remains stationary, and the sliding member is squeezed by the pushing member and slides by overcoming the elastic force of the elastic member;

[0015] The second contact state is: after the sliding member slides in place and remains stationary, the pushing member rotates by overcoming the elastic force of the elastic biasing member.

[0016] In one embodiment, the tray positioning device further includes a vibration mechanism. The vibration mechanism includes a driving member and a top member. The driving member provides a driving force to drive the top member to push the sliding member and the pushing member to move in a direction away from the loading movement path. When the driving force is removed, the pushing member and the sliding member rebound and impact the tray under the action of the elastic biasing member to generate vibration.

[0017] In one embodiment, the tray positioning device includes a positioning panel, on which a tray positioning opening is formed. The pushing mechanism is provided in multiple groups at the edge of the tray positioning opening, and the pushing directions of at least two of them intersect.

[0018] The present application also adopts the following technical solution: a chip testing and sorting machine, including a testing device and the tray positioning device as described in any of the above embodiments.

[0019] The pushing member included in the tray positioning device provided by the present application is connected to the mounting seat in a swinging manner around an axis. During the positioning process, the pushing member performs a rotational motion. Compared with the linear sliding motion along the axis, the pushing member in the solution of the present application is uniformly stressed, moves smoothly, is not easily stuck, and can provide reliable and accurate positioning for the tray.

The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0039] Please refer to Figures 1 to 11 As shown, this application provides a tray positioning device. The tray positioning device includes a tray mechanism 20 that supports a tray 100, and a pushing mechanism 30 that can apply a force to the tray 100 during the loading movement of the tray mechanism 20 to position the tray 100 to a reference position. The pushing mechanism 30 includes a mounting seat 31, a pushing member 32 movably mounted on the mounting seat 31, and an elastic force-applying member 33 disposed between the mounting seat 31 and the pushing member 32. The pushing member 32 is hinged to the mounting seat 31 and can swing relative to the mounting seat 31; wherein, when the pushing member 32 is pushed and squeezed by the tray 100, it overcomes the elastic force of the elastic force-applying member 33 and rotates away from the loading movement path of the tray mechanism 20, and when not being pushed and squeezed, it rotates close to the loading movement path of the tray mechanism 20 under the action of the elastic force of the elastic force-applying member 33.

[0040] The tray positioning device provided by the present application can solve the problem of jamming caused by the linear sliding of the pushing member 32 along the axis. The pushing member 32 included in the tray positioning device provided by the present application is connected to the mounting base 31 in a manner of swinging around the axis. During the positioning movement, the pushing member 32 can perform rotational movement. Compared with the linear sliding movement along the axis, the pushing member 32 in the solution of the present application is uniformly stressed, moves smoothly, is not prone to jamming, and can provide reliable and accurate positioning for the tray 100.

[0041] Please refer to Figures 1 to 4 As shown, in an embodiment, the tray positioning device includes a positioning panel 10, and a tray positioning opening 101 is formed on the positioning panel 10. The tray mechanism 20 is driven by the lifting mechanism 11 to move up and down to realize the picking and loading of the tray 100. For example, in this embodiment, the tray mechanism 20 is driven by the lifting mechanism 11 to descend to a set position below the positioning panel 10. Here, the tray 100 is placed on the tray mechanism 20, and then the lifting mechanism 11 drives the tray mechanism 20 carrying the tray 100 to rise, and finally the tray 100 in the tray positioning opening 101 is positioned to the reference position under the action of the pushing mechanism 30. Among them, the path of the tray mechanism 20 and the tray 100 carried by it driven by the lifting mechanism 11 to move up and down is the loading movement path. The pushing mechanism 30 is in multiple groups, arranged at the edge of the tray positioning opening 101, and at least two of the pushing directions intersect, so that the tray 100 is pushed towards a corner for positioning, ensuring the uniqueness of the reference position and the accuracy of positioning. In this embodiment, both the tray positioning opening 101 and the tray mechanism 20 are generally rectangular in shape, and the reference position is a reference post 23 provided at a corner of the tray mechanism 20. When the corner of the tray 100 is in place in cooperation with the reference post 23, the positioning is completed. Further, to improve the positioning effect of the tray 100, there are no less than two and spaced-apart reference posts 23 provided on each side of the rectangular tray 100.

[0042] Please refer to Figure 5 and Figure 6 As shown, in an embodiment, the tray mechanism 20 includes a tray body 21 and a chuck assembly 22. The chuck assembly 22 is used to cooperate with the pushing mechanism 30 to drive the tray 100 to move towards the reference position under the push of the pushing mechanism 30.

[0043] Please refer to Figure 6 and Figure 7As shown, in this embodiment, the chuck assembly 22 includes a fixed seat 221 fixed to the tray body 21, a sliding member 223 slidable relative to the fixed seat 221, and an elastic member 225 disposed between the fixed seat 221 and the sliding member 223. The fixed seat 221 is fixed to the bottom surface of the tray body 21, and a slide rail 222 is installed on the fixed seat 221. The sliding member 223 is slidably installed on the slide rail 222. Without external force, the sliding member 223 is under the elastic force of the elastic member 225 and is in a position relatively far from the edge of the tray body 21. When the sliding member 223 contacts the pushing mechanism 30, it will be pushed by the extrusion force of the pushing mechanism 30 to move the tray 100 towards the reference position. At the same time, the sliding member 223 will compress the elastic member 225 and deform, and move towards the direction close to the edge of the tray body 21.

[0044] Please continue to refer to Figure 7 As shown, in this embodiment, the sliding member 223 includes a vertically extending plug member 224 for contacting the pushing member 32. Using the plug member 224 to contact the pushing member 32 can have a larger contact area, more balanced force, and is beneficial to the sliding of the sliding member 223. In this embodiment, a guiding inclined surface 2241 is provided on the surface of the plug member 224 in contact with the pushing member 32. The guiding inclined surface 2241 makes the upper half of the plug member 224 a wedge-shaped body with a gradually increasing thickness from top to bottom. The setting of the guiding inclined surface 2241 can make the cooperation and pushing amount between the plug member 224 and the pushing member 32 gradually increase during the upward movement of the plug member 224, so that the force and movement of the sliding member 223 are carried out smoothly and gradually.

[0045] Please refer to Figures 8 to 11 As shown, the pushing mechanism 30 includes a mounting seat 31, a pushing member 32 movably installed on the mounting seat 31 for abutting against the tray mechanism 20, and an elastic force-applying member 33 disposed between the mounting seat 31 and the pushing member 32. In one embodiment, the pushing member 32 includes a swing arm 321 and a roller 322 pivotally connected to the swing arm 321. One end of the swing arm 321 is connected to the mounting seat 31 through a pivot shaft 323, and the roller 322 is rotatably installed on the end of the swing arm 321 away from the pivot shaft 323 through a roller shaft 324. The roller 322 protrudes partially from the swing arm 321 and can abut against the tray mechanism 20. In this embodiment, the roller 322 abuts against the chuck assembly 22 of the tray mechanism 20. During the abutting process, the roller 322 can rotate to achieve rolling contact with the chuck assembly 22, which can reduce wear and relieve jamming compared with sliding contact. In other embodiments, the pushing member 32 includes a swing arm 321. By moving the tray mechanism 20, the swing arm 321 directly abuts against the plug member 224, and the driving effect on the plug member 224 can also be achieved.

[0046] The elastic biasing member 33 is disposed between the mounting base 31 and the swing arm 321 of the pushing member 32 and is always in a compressed state. The elastic biasing member 33 applies a force to a position of the swing arm 321 above the pivot shaft 323, so that when the pushing member 32 is not subjected to an external force, the end of the swing arm 321 connected with the roller 322 remains at a position away from the mounting base 31. That is, when not subjected to an external force, the end of the swing arm 321 connected with the roller 322 remains in a state of protruding toward the tray mechanism 20, so as to be able to contact the tray mechanism 20 in time during the feeding process. In this embodiment, one end of the swing arm 321 provided with the pivot shaft 323 abuts against the mounting base 31 under the action of the elastic biasing member 33 to define the maximum position where the pushing member 32 rotates and protrudes toward the feeding movement path side close to the tray mechanism 20. In other words, the lower end of the swing arm 321 abuts against the mounting base 31 to define the maximum distance that the upper end of the swing arm 321 can rotate relative to the mounting base 31. It should be noted that the above description is made by taking the elastic biasing member 33 as a compression spring as an example. It can be understood that in other embodiments, the elastic biasing member 33 can also adopt a tension spring that applies a force to the lower end of the swing arm 321 by tensile deformation, or a torsion spring sleeved on a shaft, or a force-applying member such as a metal elastic sheet.

[0047] Please continue to refer to Figures 9 to 11 As shown, in this embodiment, the elastic biasing member 33 is arranged to be slidable relative to the swing arm 321 or the mounting base 31 to avoid bending of the elastic biasing member 33 when the swing arm 321 swings relative to the mounting base 31. Specifically, the mounting base 31 is provided with a mounting position 310 for mounting one end of the elastic biasing member 33. The mounting position 310 is a counterbore matching the end of the elastic biasing member 33. For example, in this embodiment, the elastic biasing member 33 is a columnar spring, and the mounting position 310 is a cylindrical counterbore; the swing arm 321 is provided with a mounting groove 3210 for accommodating the other end of the elastic biasing member 33. The mounting groove 3210 is a long strip groove to allow the end of the elastic biasing member 33 to slide in the mounting groove 3210 when the swing arm 321 swings relative to the mounting base 31. Since the movement of the swing arm 321 is a swing, the movement trajectories of each point on it are arcs rather than straight lines. Therefore, if both ends of the elastic biasing member 33 are fixed, during the swinging process of the swing arm 321, the elastic biasing member 33 will be arcuately bent, which will affect its force application state and service life. The further solution of this application avoids the problem of bending of the elastic biasing member 33 by making at least one end of the elastic biasing member 33 slidable. In other embodiments, the elastic biasing member 33 can also be arranged to be slidable relative to the mounting base 31. For example, the mounting base 31 is provided with a long strip groove, and the swing arm 321 is provided with a cylindrical groove, etc. In another embodiment, the problem of bending of the columnar spring can also be overcome by arranging the elastic biasing member 33 as a torsion spring.

[0048] Please refer to again Figures 1 to 4As shown, the pushing mechanism 30 and the tray mechanism 20 have a first contact state and a second contact state. Among them, the first contact state is that the pusher 32 remains stationary, and the slider 223 is extruded by the pusher 32 and slides against the elastic force of the elastic member 225. The second contact state is that after the slider 223 slides in place, it remains stationary, and the pusher 32 rotates against the elastic force of the elastic force applying member 33. The elastic force of the elastic force applying member 33 is greater than the elastic force of the elastic member 225.

[0049] That is, in this embodiment, the feeding movement process is as follows: after placing the tray 100 on the tray mechanism 20, the tray mechanism 20 and the tray 100 rise upward together. When the stroke is about to reach the end, the chuck assembly 22 contacts the pushing mechanism 30. Since the elastic force of the elastic force applying member 33 of the pushing mechanism 30 is much greater than the elastic force of the elastic member 225 of the chuck assembly 22, the elastic member 225 of the chuck assembly 22 will be compressed first. At this time, the tray 100 will be extruded toward the X-direction and Y-direction reference posts 23 on the tray mechanism 20. As the tray mechanism 20 gradually rises, the elastic member 225 of the chuck assembly 22 will be gradually compressed until the tray 100 completely contacts the X-direction and Y-direction reference posts 23 on the tray mechanism 20, thereby completing the precise positioning of the tray 100. After the tray 100 is completely positioned, the chuck assembly 22 will stop moving under force. Since the tray mechanism 20 is still rising and the chuck assembly 22 cannot be further compressed under force, at this time, the pusher 32 of the pushing mechanism 30 will be compressed under force until the tray mechanism 20 is lifted in place, completing the precise positioning of the tray 100 in the tray mechanism 20. After the operation of picking and placing the chips in the tray 100 is completed, the tray mechanism 20 descends, and the components included in the pushing mechanism 30 and the chuck assembly 22 return to the initial state due to the elastic force, waiting for the next feeding. The solution of the present application can achieve passive positioning through the upward movement and reset through the downward movement, eliminating control components such as cylinders, realizing autonomous and precise positioning, and having a more concise structure.

[0050] It should be noted that in this embodiment, the pushing mechanism 30 applies force to the tray 100 through the chuck assembly 22 to push the tray 100 to move toward the reference position. It can be understood that in other embodiments, the pushing mechanism 30 can also directly contact the tray 100 to push the tray 100 to move and position. In short, the pushing mechanism 30 applying force to the tray 100 in an intermittent contact or direct contact manner is the solution disclosed and protected by the present application.

[0051] Such as Figure 4 and Figure 6As shown in the figure, further, in this embodiment, the tray positioning device further includes a vibration mechanism 40. The vibration mechanism 40 includes a driving member 41 and a top member 42. The driving member 41 provides a driving force to drive the top member 42 to push the sliding member 223 and the pushing member 32 to move away from the feeding movement path. When the driving force is removed, the pushing member 32 and the sliding member 223 rebound under the action of the elastic biasing member 33 to impact the tray 100 to generate vibration.

[0052] After the tray 100 is lifted in place, the manipulator will perform a feeding operation on the tray 100. The chips in the tray 100 are not completely fixed, and their states are various. Moreover, during the feeding process of the manipulator, it is inevitable that the feeding of the manipulator will fail due to the poor state of the chips in the tray 100, such as chip warping. Therefore, through the above vibration mechanism 40, the present application can realize the knocking vibration of the tray 100, so that the chips with poor placement states in the tray 100 return to their original positions, thereby increasing the placement rate of the chips in the tray 100 and improving the success rate of the manipulator feeding. In this embodiment, the driving member 41 is a cylinder, and the top member 42 is a cylinder rod. After the tray 100 is lifted in place, the cylinder will start to perform a punching - retracting movement. When the cylinder punches, through the impact of the cylinder rod on the side connecting member 43, the chuck assembly 22 is forced to pop out. The punching force of the cylinder is greater than the elastic force of the elastic biasing member 33, so that the elastic biasing member 33 will be further stressed and contracted; when the cylinder rod quickly retracts, the elastic biasing member 33 will cause the sliding member 223 of the chuck assembly 22 to be quickly bounced back, and then collide with the positioning edge of the tray 100 and stop. This impact will cause the chips in the tray 100 to vibrate and return to their positions. In this embodiment, the driving member 41 and the top member 42 are arranged beside the sliding member 223. A side connecting member 43 is connected to the side surface of the sliding member 223. The driving member 41 drives the top member 42 to extend to push the side connecting member 43 to push the sliding member 223 and the pushing member 32 to move. In this embodiment, the vibration mechanism 40 is arranged to knock and vibrate the tray 100 along the X - direction. It can be understood that in other embodiments, the vibration mechanism 40 can also be arranged to knock and vibrate the tray 100 along the Y - direction.

[0053] The present application also provides a chip testing and sorting machine, which includes a magazine device for carrying trays, a transfer device for transferring test trays carrying chips, a transfer device for transferring chips between the magazine device and the test trays, and a testing device for testing the chips on the test trays during the transfer of the test trays by the transfer device. The magazine device is used to supply / receive trays to / from the transfer device, and the above - mentioned tray positioning device is arranged in the magazine device. In one embodiment, while the magazine device supplies a tray to the transfer device, it positions the position of the tray to ensure the position of the chips picked up by the transfer device from the tray.

[0054] As can be seen from the above description of the specific embodiments, the tray positioning device provided in the present application includes a pushing member 32 connected to the mounting base 31 in a manner of swinging around an axis. During the process that the pushing member 32 contacts the chuck assembly 22 to push the chuck assembly 22 to be positioned at the reference position, the pushing member 32 rotates. Compared with the movement along a linear sliding shaft, the pushing member 32 in the solution of the present application is uniformly stressed, moves smoothly, is not prone to jamming, and can provide reliable and accurate positioning for the tray 100.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0056] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
