Description

Technical Field

[0001] This utility model belongs to the technical field of chip testing, and in particular relates to a robotic arm for chip testing. Background Technology

[0002] With the continuous development of chip technology, chip testing technology has become a crucial technology in the electronics industry for ensuring product quality and accelerating production processes. Generally, packaged chips require multiple tests. Currently, during chip testing, the process involves manual handling of the chip before moving to the next test. This manual transfer of the chip during transit can cause chip damage or inaccurate testing due to repositioning issues, and the testing efficiency is relatively low.

[0003] Therefore, there is a need to provide a robotic arm for chip testing to achieve efficient and complete chip transfer. Utility Model Content

[0004] The main objective of this invention is to provide a robotic arm for chip testing, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A robotic arm for chip testing includes a main base and an auxiliary base arranged in parallel. A linear drive module is fixedly mounted on the main base, and a slide rail is fixedly mounted on the auxiliary base. A first slider is slidably connected to the slide rail, and the direction in which the first slider moves along the slide rail is consistent with the direction in which the linear drive module moves. A vertical plate is provided between the main base and the auxiliary base. One end of the vertical plate is fixedly connected to the slide table of the linear drive module, and the other end of the vertical plate is fixedly connected to the first slider. Guide rails are arranged parallel and spaced apart on the upper and lower ends of the front end face of the vertical plate. A second slider is slidably connected to each guide rail. The second sliders at the upper and lower ends are connected by a hollow gripper base. A drive assembly for driving the gripper base to move along the guide rail is also fixedly mounted on the vertical plate.

[0007] Preferably, the driving assembly includes limiting blocks fixed on both sides of the front end face of the upright plate, one of the limiting blocks being relatively close to the main base and the other limiting block being relatively close to the auxiliary base. The driving assembly also includes a drive motor, a drive belt, and a ball screw. The drive motor is connected to the drive belt via a rotating shaft. The drive belt has a rotating gear inside, which is connected to the ball screw. One end of the ball screw is fixed to the limiting block relatively close to the main base, and the other end of the ball screw passes through the gripper base and extends to the limiting block relatively close to the auxiliary base. The nut on the ball screw abuts against the gripper base. The drive motor drives the drive belt to drive the ball screw, thereby enabling the ball screw to drive the gripper base to reciprocate along the guide rail.

[0008] Preferably, the overall height of the linear drive module and the main base is the same as the overall height of the slide rail and the auxiliary base.

[0009] Preferably, both ends of the slide rail in the direction of travel are fitted with stops that are fixedly connected to the auxiliary base.

[0010] Preferably, a sensing plate is provided on the outer side of the slide table, and sensors for detecting the position of the sensing plate are provided at both ends of the outer side of the linear transmission module in the direction of operation, and the sensors and the sensing plate are on the same side.

[0014] ② The drive assembly can drive the gripper base to move back and forth along the guide rail. The drive motor drives the drive belt through the rotating shaft.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0023] like Figures 1 to 4 As shown, a chip testing robot includes a main base 1 and an auxiliary base 2 arranged in parallel. A linear transmission module 3 is fixedly installed on the main base 1, and a slide rail 4 is fixedly installed on the auxiliary base 2. A first slider 5 is slidably connected to the slide rail 4. The direction of movement of the first slider 5 along the slide rail 4 is consistent with the direction of movement of the linear transmission module 3. A vertical plate 7 is arranged between the main base 1 and the auxiliary base 2. One end of the vertical plate 7 is fixedly connected to the slide table 6 of the linear transmission module 3, and the other end of the vertical plate 7 is fixedly connected to the first slider 5. The upper and lower ends of the front end face of the vertical plate 7 are arranged with parallel and spaced guide rails 8. A second slider 9 is slidably connected to each guide rail 8. The upper and lower ends of the second sliders 9 are connected by a hollow gripper base 10. A driving component for driving the gripper base 10 to move along the guide rail 8 is also fixedly installed on the vertical plate 7. It can be understood that a gripper for gripping the chip is fixedly installed on the gripper base 10. Since the gripper is within the scope of prior art, it is not shown in the figure.

[0024] In this embodiment, a robotic arm can be used to transfer the chips to be tested to different testing stations, which can improve the transfer efficiency of the chips and ensure the integrity of the chip structure.

[0025] The working principle of the robotic arm in this embodiment:

[0026] When the gripper base 10 with grippers needs to move along the direction of the vertical plate 7 along the linear drive module 3 and the slide rail 4, the motor of the linear drive module 3 is started. One end of the vertical plate 7 slides along the linear drive module 3 with the slide table 6, and the other end slides along the slide rail 4 with the first slider 5. Both ends of the vertical plate 7 move at the same time, which can realize the movement of the gripper base 10. When the gripper base 10 needs to move along the direction of the vertical plate 7, the drive component is started. The drive component drives the gripper base 10 to move along the guide rail 8, thereby realizing the movement of the gripper base 10 in different directions.

[0027] The drive assembly includes limiting blocks 11 fixed on both sides of the front end face of the upright plate 7. One limiting block 11 is relatively close to the main base 1, and the other limiting block 11 is relatively close to the auxiliary base 2. The function of the two limiting blocks 11 is to fix the position of the drive assembly. The drive assembly also includes a drive motor 12, a drive belt 14, and a ball screw 16. The output end of the drive motor 12 is connected to the rotating shaft 13, and the drive motor 12 is connected to the drive belt 14 through the rotating shaft 13. The drive belt 14 is provided with a rotating gear 15, which is connected to the ball screw 16. After the drive motor 12 is started, it drives the rotating shaft 13 to rotate. The rotating shaft 13 rotates and drives the rotation of the drive belt 14, which in turn drives the ball screw 16. Rotation occurs when one end of the ball screw 16 is fixed to the limiting block 11, which is relatively close to the main base 1, and the other end of the ball screw 16 passes through the gripper base 10 and extends to the limiting block 11, which is relatively close to the auxiliary base 2. The nut 17 on the ball screw 16 abuts against the gripper base 10. In this way, the transmission motor 12 drives the transmission belt 14 to drive the transmission. The rotation of the transmission belt 14 drives the rotating gear 15 inside it to rotate. The rotating gear 15 drives the ball screw 16 to drive within the hollow gripper base 10. Since the nut 17 on the ball screw 16 abuts against the gripper base 10, the rotation of the ball screw 16 can drive the gripper base 10 to move along the guide rail 8, thus achieving the purpose of the ball screw 16 driving the gripper base 10 to reciprocate along the guide rail 8.

[0028] To ensure the balance of the upright plate 7 as it moves back and forth along the linear drive module 3 and the slide rail 4, the overall height of the linear drive module 3 and the main base 1 and the overall height of the slide rail 4 and the auxiliary base 2 are set to be the same. Furthermore, the gripper base 10 on the upright plate 7 can also maintain balance when it moves, and the clamps holding the chips on the gripper base 10 can maintain balance during operation, so as not to damage the chips. The gripper base 10 can also maintain balance when it moves back and forth along the guide rail 8, which also provides protection for chip transfer and avoids unnecessary chip loss.

[0029] Both ends of the slide rail 4 in the direction of travel are fitted with stop blocks 18 that are fixedly connected to the auxiliary base 2. The stop blocks 18 can effectively prevent the first slider 5 from sliding out of the slide rail 4, causing damage to the robot arm structure and chip.

[0030] To maintain the synchronous movement of the upright plate 7 on the linear drive module 3 and the slide rail 4, a sensing plate 19 is provided on the outer side of the slide table 6. Sensors 20 for detecting the position of the sensing plate 19 are provided at both ends of the outer side of the linear drive module 3 in the direction of operation. The sensors 20 and the sensing plate 19 are on the same side. Normally, the sensor used is a position sensor. To ensure the synchronous movement of the upright plate 7 during operation, the positions of the stop block 18 and the sensor 20 are set to be relatively flush, that is, relatively on the same line.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
