Description

Technical Field

[0001] This invention relates to the field of chip sorting technology, specifically a chip testing and sorting robot that employs multi-station synchronous rotation. Background Technology

[0002] Under normal circumstances, after the chip manufacturing process is completed, a crucial task must be carried out: chip testing. This testing stage is of paramount importance, its main purpose being to thoroughly detect any potential problems hidden within the chip using a series of carefully designed testing methods and techniques. This ensures that the number of defects in the final chip product reaching the consumer is minimized.

[0003] During chip testing, specialized fixtures are typically used for precise chip positioning. Once the testing process is complete, the fixtures automatically release, ceasing to apply clamping force to the chips. Workers then remove the chips from the fixtures, separating qualified and unqualified chips into different areas or containers. This traditional sorting method is relatively inefficient, involves high worker workload, and is difficult to meet the demands of large-scale, high-efficiency production.

[0004] For example, in the prior art, patent announcement number CN120233127A discloses a chip rotation test fixture, a chip test device, and a chip test machine. The chip rotation test fixture includes a rotary table, multiple trays, and a material support rack. The multiple trays are arranged circumferentially on the rotary table, and the rotation trajectory of the trays is provided with loading and unloading positions.

[0005] In the above scheme, after the entire chip testing process is completed, the fixture automatically releases. At this point, workers need to remove the chips from the fixture and place the qualified and unqualified chips in different areas or containers, resulting in high workload for workers. Therefore, a chip testing and sorting robot with multi-station synchronous rotation is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a chip testing and sorting robot that employs multi-station synchronous rotation to solve the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a chip testing and sorting robot employing multi-station synchronous rotation, comprising a rotary table, on which a chip rotation testing fixture is fixedly mounted; a first conveyor belt and a second conveyor belt are mounted on one side of the rotary table; blocks are fixedly mounted above both the first and second conveyor belts; a single-axis turntable is mounted between the second conveyor belt and the rotary table; a rotating arm is fixedly mounted on the output end of the single-axis turntable; a drive assembly is fixedly mounted at the end of the rotating arm; the drive assembly includes a cylinder fixedly mounted on the rotating arm; a plunger rod is slidably mounted inside the cylinder; a clamping assembly is fixedly mounted at the lower end of the plunger rod; and a pressure relief mechanism is fixedly mounted at the upper end of the cylinder.

[0008] Preferably, an air inlet is provided at the middle position of the top of the cylinder, a one-way valve is installed in the air inlet, a first spring is provided in the cylinder, an inner groove is provided on the plunger rod, a second spring is provided in the inner groove, and the elastic coefficient of the second spring is greater than that of the first spring. A piston is slidably installed in the inner groove.

[0009] Preferably, an air supply pipe is connected to the air inlet, and an air pump is connected to the end of the air supply pipe.

[0010] Preferably, one end of the first spring is connected to the top of the cylinder, the other end of the first spring is connected to the plunger rod, one end of the second spring is connected to the piston, and the other end of the second spring is connected to the upper end of the inner slide groove.

[0011] Preferably, the clamping assembly includes a base fixedly installed at the lower end of the plunger rod, a clamping arm rotatably installed inside the base, a rubber gripper fixedly installed on the clamping arm, a linkage seat slidably installed inside the base, a drive rod fixedly installed on the linkage seat, and the upper end of the drive rod fixedly installed at the middle position of the bottom of the piston, and a connecting rod is provided between the clamping arm and the linkage seat.

[0012] Preferably, both the connecting rod and the clamping arm are equipped with a rotating shaft, and the clamping arm is rotatably mounted on the base via the rotating shaft.

[0013] Preferably, one end of the connecting rod is rotatably mounted on the linkage seat via a rotating shaft, and the other end of the connecting rod is rotatably mounted on the clamping arm via a rotating shaft. The base has a through hole, and the driving rod extends out of the base through the through hole.

[0014] Preferably, the pressure relief mechanism includes a pressure relief pipe fixedly installed on the cylinder body, a ring seat fixedly installed inside the pressure relief pipe, a pressure rod slidably installed on the ring seat, a sealing cover fixedly installed at the lower end of the pressure rod, a sealing gasket fixedly installed on the sealing cover, a spring seat fixedly installed at the upper edge of the pressure rod, air holes are provided on both the spring seat and the ring seat, and a third spring is sleeved on the pressure rod.

[0015] Preferably, a sliding hole is provided in the middle of the ring seat, and the pressure rod is slidably installed on the ring seat through the sliding hole.

[0016] Preferably, one end of the third spring is connected to the ring seat, the other end of the third spring is connected to the spring seat, and the sealing cover is movably installed at the lower end of the pressure relief pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In this application, after the rubber grippers are positioned above the chip, gas can be injected into the cylinder through the air inlet. As the internal gas pressure of the cylinder increases, the plunger rod will move downwards, thereby moving the rubber grippers to both sides of the chip. After the rubber grippers have moved to both sides of the chip, gas can continue to be injected into the cylinder. As the internal gas pressure continues to increase, the piston will overcome the elastic force of the second spring and move downwards. When the piston moves downwards, it will drive the drive rod to move downwards; when the drive rod moves downwards, it will drive the linkage seat to move downwards; when the linkage seat moves downwards, the connecting rod will drive the two gripping arms to close, thereby allowing the rubber grippers to hold the chip.

[0018] 2. In this application, the qualified chips picked up by the rubber grippers are moved above the first conveyor belt, while the unqualified chips are picked up by the rubber grippers and moved above the second conveyor belt. When the chips are moved above the conveyor belt, the pressure rod is displaced downward by the stop block, causing the sealing cover to move downward synchronously, separating the sealing cover from the lower end of the pressure relief pipe, releasing the seal of the pressure relief pipe, and allowing the gas in the cylinder to be discharged. After the gas is discharged, the second spring force pushes the piston upward, causing the drive rod to move upward, which in turn causes the linkage seat to move upward. The upward movement of the linkage seat drives the two gripping arms to unfold, allowing the qualified chips to fall onto the first conveyor belt and the unqualified chips to fall onto the second conveyor belt, thus achieving chip sorting.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this invention provides a technical solution for a multi-station synchronously rotating chip testing and sorting robot, including a rotary table 1, on which a chip rotation testing fixture 2 is fixedly mounted. A first conveyor belt 4 and a second conveyor belt 5 are mounted on one side of the rotary table 1. Stops 3 are fixedly mounted above both the first conveyor belt 4 and the second conveyor belt 5. A single-axis turntable 6 is mounted between the second conveyor belt 5 and the rotary table 1. A rotating arm 601 is fixedly mounted on the output end of the single-axis turntable 6. A drive assembly 7 is fixedly mounted at the end of the rotating arm 601. A clamping assembly 8 is fixedly mounted at the lower end of a plunger rod 706. A pressure relief mechanism 9 is fixedly mounted at the upper end of a cylinder 701. The drive assembly 7 and the clamping assembly 8 work together to clamp the chips. The pressure relief mechanism 9, in conjunction with the rotating arm 601, allows qualified chips to fall onto the first conveyor belt 4 and unqualified chips to fall onto the second conveyor belt 5, thus achieving chip sorting.

[0023] Example 1: As Figure 4 and Figure 5As shown, the drive assembly 7 includes a cylinder 701 fixedly mounted on a rotating arm 601. A plunger rod 706 is slidably mounted inside the cylinder 701. An air inlet 702 is provided at the middle position of the top of the cylinder 701. A one-way valve 703 is installed inside the air inlet 702. A first spring 704 is provided inside the cylinder 701. An inner groove 707 is provided on the plunger rod 706. A second spring 705 is provided inside the inner groove 707. The elastic coefficient of the second spring 705 is greater than that of the first spring 704. A piston 708 is slidably mounted inside the inner groove 707. An air supply pipe is connected to the air inlet 702, and an air pump is connected to the end of the air supply pipe.

[0024] Specifically, the one-way valve 703 only allows gas to enter the cylinder 701. Gas can be supplied to the cylinder 701 through the air inlet 702. As the internal air pressure of the cylinder 701 increases, the plunger rod 706 will move downward, thereby moving the rubber grippers 805 to both sides of the chip.

[0025] After the rubber grippers 805 move to both sides of the chip, air can continue to be pumped into the cylinder 701. As the air pressure inside the cylinder 701 continues to rise, the piston 708 will overcome the elastic force of the second spring 705 and move downward. When the piston 708 moves downward, it will drive the drive rod 801 to move downward. When the cylinder 701 is depressurized, the second spring 705 pushes the piston 708 to reset. When the piston 708 resets, it will drive the drive rod 801 to move upward, thereby controlling the up and down movement of the drive rod 801.

[0026] Example 2: Figure 4 and Figure 6 As shown, the clamping assembly 8 includes a base 802 fixedly installed at the lower end of the plunger rod 706, a clamping arm 804 rotatably installed inside the base 802, a rubber gripper 805 fixedly installed on the clamping arm 804, a linkage seat 806 slidably installed inside the base 802, a drive rod 801 fixedly installed on the linkage seat 806, and the upper end of the drive rod 801 fixedly installed at the middle position of the bottom of the piston 708. A connecting rod 803 is provided between the clamping arm 804 and the linkage seat 806. A rotating shaft 807 is installed on both the connecting rod 803 and the clamping arm 804. The clamping arm 804 is rotatably installed on the base 802 through the rotating shaft 807.

[0027] Specifically, when the drive rod 801 begins to move downwards, it drives the connected linkage seat 806 to move downwards as well. During this process, the downward movement of the linkage seat 806 causes the connecting rod 803 to function, thereby driving the two gripping arms 804 to gradually close. As the gripping arms 804 close, the rubber grippers 805 can accurately pick up the chip. When the drive rod 801 moves upwards, it similarly drives the linkage seat 806 upwards. At this time, the upward movement of the linkage seat 806 causes the connecting rod 803 to generate a counterforce, thereby driving the two gripping arms 804 to unfold. With the gripping arms 804 unfolded, qualified chips fall onto the first conveyor belt 4, while unqualified chips fall onto the second conveyor belt 5. In this way, the purpose of sorting the chips is successfully achieved.

[0028] Example 3: Figure 4 , Figure 7 and Figure 8 As shown, the pressure relief mechanism 9 includes a pressure relief pipe 902 fixedly installed on the cylinder body 701. A ring seat 905 is fixedly installed inside the pressure relief pipe 902. A pressure rod 901 is slidably installed on the ring seat 905. A sealing cover 906 is fixedly installed at the lower end of the pressure rod 901. A sealing gasket 907 is fixedly installed on the sealing cover 906. A spring seat 903 is fixedly installed at the upper edge of the pressure rod 901. Air holes 908 are provided on both the spring seat 903 and the ring seat 905. A third spring 904 is sleeved on the pressure rod 901. A sliding hole is provided in the middle of the ring seat 905. The pressure rod 901 is slidably installed on the ring seat 905 through the sliding hole.

[0029] Specifically, the elastic force provided by the third spring 904 continuously acts on the pressure rod 901, causing it to move upwards. When the pressure rod 901 begins to move upwards under this upward force, it drives the connected sealing cover 906 to move as well. The sealing cover 906 is pressed tightly against the bottom of the pressure relief pipe 902, thus effectively sealing the pressure relief pipe 902 and preventing gas leakage or the entry of other substances. When the rubber gripper 805 rotates to the area above the conveyor belt, the pressure rod 901 comes into contact with the stop block 3. At this time, the stop block 3 applies a downward pressure to the pressure rod 901, causing it to be pressed down. When the pressure rod 901 is pressed down, it drives the sealing cover 906 to move downwards. As a result, the sealing cover 906 gradually moves away from the lower end of the pressure relief pipe 902, thereby releasing the original sealing state of the pressure relief pipe 902. After the pressure relief pipe 902 is released from its sealed state, the gas inside the cylinder 701 has a channel to be discharged. This gas will be discharged along the pressure relief pipe 902, thereby enabling the cylinder 701 to complete the entire pressure relief process.

[0030] Working Principle: After chip testing is completed, the chip rotation test fixture 2 rotates to one side of the conveyor belt and releases the chip from the fixture. The single-axis turntable 6 drives the rotating arm 601 to rotate, moving the rubber grippers 805 above the chip. After the rubber grippers 805 move above the chip, air is introduced into the cylinder 701 through the air inlet 702. As the internal air pressure of the cylinder 701 increases, the plunger rod 706 moves downward, thereby moving the rubber grippers 805 to both sides of the chip. After the rubber grippers 805 move to both sides of the chip, air can continue to be introduced into the cylinder 701. As the internal air pressure of the cylinder 701 continues to increase, the piston 708 overcomes the elastic force of the second spring 705 and moves downward. When the piston 708 moves downward, it drives the drive rod 801 to move downward. When the drive rod 801 moves downward, it drives the linkage seat 806 to move downward. When the linkage seat 806 moves downward, the connecting rod 803 drives the two gripping arms 804 to close, thereby causing the rubber grippers 805 to clamp the chip. If the chip picked up by the rubber gripper 805 is qualified, the rotating arm 601 can be rotated clockwise by the single-axis turntable 6, so that the rubber gripper 805 moves above the first conveyor belt 4. If the chip picked up by the rubber gripper 805 is unqualified, the rotating arm 601 can be rotated counterclockwise by the single-axis turntable 6, so that the rubber gripper 805 moves above the second conveyor belt 5. When the rubber gripper 805 rotates above the conveyor belt, the pressure rod 901 is pressed down by the stop block 3. When the pressure rod 901 is pressed down, it will drive the sealing cover 906 to move downward, so that the sealing cover 906 leaves the lower end of the pressure relief pipe 902, releasing the sealing state of the pressure relief pipe 902. After the pressure relief pipe 902 is released from the seal, the gas in the cylinder 701 is discharged. After the gas in the cylinder 701 is discharged, the second spring 705 pushes the piston 708 to move upward. When the piston 708 moves upward, it drives the drive rod 801 to move upward. When the drive rod 801 moves upward, it drives the linkage seat 806 to move upward. When the linkage seat 806 moves upward, the connecting rod 803 drives the two gripping arms 804 to unfold, causing qualified chips to fall onto the first conveyor belt 4 and unqualified chips to fall onto the second conveyor belt 5, thus achieving chip sorting.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
