[0002] With the rapid development of technology, the chip industry is growing at an increasingly fast pace. Miniaturization and multifunctionality are the development trends of the modern chip industry. Since chip manufacturing involves hundreds of steps, errors in any step can lead to device failure; therefore, the chip testing stage is crucial. Chip testing requires placing the chip between a chip testing head and a testing machine. A robotic arm drives the chip testing head to move, thus completing the chip test. Existing robotic arms are complex in structure, difficult to manufacture, and costly to produce. They are also difficult to maintain, which is detrimental to the development of small and medium-sized enterprises. Summary of the Invention

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-5 As shown, a chip testing robotic arm includes a body guide rod connecting plate 1. A first connecting shaft 6 is fixedly connected to the body guide rod connecting plate 1. A first arm segment 2 is rotatably connected to the first connecting shaft 6. A second connecting shaft 7, parallel to the first connecting shaft 6, is rotatably connected to the end of the first arm segment 2 away from the first connecting shaft 6. A second arm segment 3 is fixedly connected to the second connecting shaft 7. A third connecting shaft 8, parallel to the second connecting shaft 7, is fixedly connected to the end of the second arm segment 3 away from the second connecting shaft 7. A third arm segment 4 is rotatably connected to the third connecting shaft 8. A fourth connecting shaft 9, perpendicular to the third connecting shaft 8, is fixedly connected to the end of the third arm segment 4 near the third connecting shaft 8. A test head fixing arm 5 is rotatably connected to the fourth connecting shaft 9. The first connecting shaft 6, the second connecting shaft 7, and the third connecting shaft 8 are all horizontally positioned, allowing the first arm segment 2, the second arm segment 3, and the third arm segment 4 to rotate relative to their respective connecting shafts. The rotation of the first arm segment 2 around the first connecting shaft 6 and the rotation of the second arm segment 3 around the second connecting shaft 7 drives the third arm segment 4 to move up and down and left and right, thereby enabling the connected test head fixing arm 5 to move up and down and left and right, facilitating chip testing by the chip test head connected to the test head fixing arm 5. Simultaneously, the rotatability of the first arm segment 2, the second arm segment 3, and the third arm segment 4 allows the test head fixing arm 5 to rotate at a certain angle. The fourth connecting shaft 9 is vertically positioned, allowing the test head fixing arm 5 to rotate back and forth, thereby driving the chip test head to rotate back and forth, achieving chip testing.

[0021] In this application, a push rod 14 is provided at the end of the third arm 4 furthest from the fourth connecting shaft 9. The push rod 14 passes through the third arm 4 and is perpendicular to both the third connecting shaft 8 and the fourth connecting shaft 9. The push rod 14 can push the test head fixing arm 5 to rotate back and forth around the fourth connecting shaft 9, thus achieving a certain angle of rotation. In this application, the testing robotic arm is connected to the body of the testing machine. The body of the testing machine can drive the testing robotic arm to move the chip testing head, enabling back-and-forth, left-and-right, and up-and-down movement, as well as rotation at a certain angle. This allows for testing of chips at different positions or angles, making it widely applicable. The testing robotic arm has a simple structure, is easy to manufacture, has low production costs, and is convenient for manual adjustment, which is beneficial for the use and development of small and medium-sized enterprises.

[0022] In this application, the first arm 2 is provided with a spring lock 10, which includes two spring pressure plates 101. The two spring pressure plates 101 are symmetrically arranged and a balance bar 103 is connected between the two spring pressure plates 101. The ends of the two spring pressure plates 101 away from the balance bar 103 are provided with locking holes 102. The side of the balance bar 103 is provided with an eccentric shaft 104 perpendicular to it. The first connecting shaft 6 and the second connecting shaft 7 are respectively inserted into the two locking slots 102. Since the first connecting shaft 6 is fixedly connected to the fuselage guide rod connecting plate 1 and the second connecting shaft 7 is fixedly connected to the second segment arm 3, the locking slots 102 can lock the first connecting shaft 6 and the second connecting shaft 7, preventing the first segment arm 2 from rotating relative to the fuselage guide rod connecting plate 1 and the second segment arm 3 from rotating relative to the first segment arm 2. This achieves the positioning and fixing of the relative position and angle of the fuselage guide rod connecting plate 1, the first segment arm 2 and the second segment arm 3. The elastic pressure plate 101 is inclined vertically, with the end of the elastic pressure plate 101 near the balance strip 103 higher than the locking slot 102. At both ends, the eccentric shaft 104 is located in the middle and below the balance bar 103. By rotating the eccentric shaft 104, the eccentric shaft 104 can contact or separate from the balance bar 103. When the protruding part of the eccentric shaft 104 rotates upward to the position of the balance bar 103, the eccentric shaft 104 can press the balance bar 103 upward, causing the balance bar 103 to move upward, which in turn drives the elastic pressure plate 101 to move upward, making the diameter of the locking opening 102 smaller, thus realizing the locking function of the locking opening 102. This achieves the locking of the first connecting shaft 6 and the second connecting shaft 7, and realizes the relative fixation of the second section arm 3, the first section arm 2, and the body guide rod connecting plate 1.

[0023] In this application, a first locking handle 11 is provided at the end of the eccentric shaft 104 away from the eccentric shaft 104. The eccentric shaft 104 can be rotated through the first locking handle 11, thereby realizing the locking or unlocking function of the lock 102.

[0024] In this application, two first bearing fixing blocks 16 are provided on the side of the third arm 4 near the second arm 3. The two ends of the third connecting shaft 8 are respectively inserted into the two first bearing fixing blocks 16, and the first bearing fixing blocks 16 realize the rotatable connection between the third connecting shaft 8 and the third arm 4. A locking block 12 is sleeved on the end of the third connecting shaft 8 near the fourth connecting shaft 9. The locking block 12 is fixed on the third arm 4. The locking block 12 is connected to a second locking handle 13. By rotating the second locking handle 13, the locking block 12 can be driven to lock the third connecting shaft 8, thereby realizing the positioning and fixing of the third arm 4 relative to the second arm 3.

[0025] In this application, two second bearing fixing blocks 17 are provided on the side of the test head fixing arm 5 near the third segment arm 4. The two ends of the fourth connecting shaft 9 are respectively inserted into the two second bearing fixing blocks 17, and the test head fixing arm 5 and the third segment arm 4 are rotatably connected through the second bearing fixing blocks 17.

[0026] In this application, the push rod 14 is screwed to the third arm 4. The end of the push rod 14 away from the test head fixing arm 5 is provided with a rotating handle 15. By rotating the handle 15, the push rod 14 can be rotated, so that the push rod 14 rotates around the third arm 4, thereby adjusting the extension length of the push rod 14 relative to the third arm 4, and thus adjusting the angle of the test head fixing arm 5 relative to the third arm 4.

[0027] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
