[0028] like Figure 1-6 As shown, a feeding turning device in this embodiment includes a base 1, a moving base 2, a rotating base 3 and a driving mechanism 4, wherein the moving base 2 is slidably connected to the base 1, the rotating base 3 is rotatably connected to the moving base 2 through a pin 5, and the driving mechanism 4 is rotatably connected to the pin 5, and the driving mechanism 4 is used to drive the pin 5 to translate and rotate;

[0029] The feeding turning device has the following two states:

[0030] In the first state, the rotating seat 3 is arranged horizontally;

[0031] In the second state, the rotating seat 3 is arranged tilted;

[0032] When the feeding turning device switches from the first state to the second state, the pin shaft 5 is first rotated by the driving mechanism 4, and the rotation of the pin shaft 5 drives the rotating seat 3 to rotate synchronously to the inclined state. Subsequently, the pin shaft 5 is translated by the driving mechanism 4 again, and the translation of the pin shaft 5 drives the moving seat 2 to move synchronously by a set distance.

[0033] When the feeding turning device switches from the second state to the first state, the driving mechanism 4 is used to firstly make the pin shaft 5 rotate in the opposite direction, and the opposite rotation of the pin shaft 5 drives the rotating seat 3 to rotate synchronously to the horizontal state, and then the driving mechanism 4 is used again to make the pin shaft 5 translate in the opposite direction, and the opposite translation of the pin shaft 5 drives the moving seat 2 to move synchronously by the set distance;

[0034] During operation, after the material tube 12 is tilted, the chips 13 in the material tube 12 slide out one by one. At this time, the feeding and flipping device is in the second state, and a chip 13 that slides out is transported to the tilted rotating seat 3. Subsequently, the pin shaft 5 is rotated by the driving mechanism 4, and the rotation of the pin shaft 5 drives the rotating seat 3 to rotate synchronously to a horizontal state, so that the chip 13 on the rotating seat 3 is converted to a horizontal state. After that, the pin shaft 5 is translated by the driving mechanism 4 again, and the translation of the pin shaft 5 drives the moving seat 2 to move synchronously by a set distance, providing space for grabbing the chip 13 on the rotating seat 3. At this time, the feeding and flipping device is in the first state, and then, the chip 13 in a horizontal state on the rotating seat 3 is grabbed to the test position by the subsequent test system. Finally, the feeding and flipping device is switched from the first state to the second state to realize the conversion of the angle of the next chip 13. Compared with the prior art that uses an arc track to realize the conversion of the angle of the chip 13, the volume of the feeding and flipping device is reduced, saving the operating space.

[0035] The driving mechanism 4 includes a driving unit 41, a transmission seat 42 and a connecting rod 43. The driving unit 41 is used to drive the transmission seat 42 to move. The moving direction of the transmission seat 42 is the same as the sliding direction of the moving seat 2. The transmission seat 42 is provided with an arc groove 44. One end of the connecting rod 43 is fixedly provided on the pin 5, and the other end of the connecting rod 43 is connected to the arc groove 44.

[0036] Two first stoppers 6 are fixedly arranged on the base 1, and the two first stoppers 6 are distributed along the sliding direction of the movable seat 2, and the movable seat 2 is located between the two first stoppers 6;

[0037] A roller 45 is installed at one end of the connecting rod 43 away from the pin 5. The roller 45 is located in the arc groove 44. The width of the roller 45 is equal to the width of the arc groove 44.

[0038] When the feeding turning device switches from the first state to the second state, the driving seat 42 is driven to move by the driving unit 41. During the movement of the driving seat 42, relative sliding occurs between the roller 45 and the arc groove 44, and a thrust is generated on the roller 45 through the inner wall of the arc groove 44, so that the roller 45 drives the connecting rod 43 to rotate, and the rotation of the connecting rod 43 drives the pin 5 to rotate around the axis of the pin 5, that is, the rotation of the rotating seat 3 is realized, so that the rotating seat 3 is rotated to the inclined state. When the roller 45 abuts against one end of the annular groove, as the driving seat 42 continues to move in the same direction, the driving seat 42 drives the roller 45 to move, and the movement of the roller 45 drives the pin 5 to move synchronously through the connecting rod 43, that is, the synchronous movement of the rotating seat 3 and the moving seat 2 is realized until the moving seat 2 abuts against one of the first limiters 6;

[0039] When the feeding turning device switches from the second state to the first state, the driving seat 42 is driven to move in the opposite direction by the driving unit 41. During the movement of the transmission seat 42, relative sliding occurs between the roller 45 and the arc groove 44, and a reverse thrust is generated on the roller 45 through the inner wall of the arc groove 44, so that the roller 45 drives the connecting rod 43 to rotate in the opposite direction. The reverse rotation of the connecting rod 43 drives the pin 5 to rotate in the opposite direction around the axis of the pin 5, that is, the reverse rotation of the rotating seat 3 is realized, so that the rotating seat 3 is reversely rotated to a horizontal state. When the roller 45 abuts against the other end of the annular groove, as the transmission seat 42 continues to move, the transmission seat 42 drives the roller 45 to move synchronously. The movement of the roller 45 drives the pin 5 to move synchronously through the connecting rod 43, that is, the synchronous movement of the rotating seat 3 and the moving seat 2 is realized until the moving seat 2 abuts against the other first limiter 6.

[0040] The driving unit 41 includes a first slide rail 411 and a first sliding seat 412. The first slide rail 411 is parallel to the sliding direction of the moving seat 2. The first slide rail 411 is fixedly arranged on the base 1. The first sliding seat 412 is installed on the first slide rail 411. The first sliding seat 412 is driven to move by a cylinder 413. The first sliding seat 412 is fixedly connected to the transmission seat 42. When the cylinder 413 is started, the first sliding seat 412 moves on the first slide rail 411. The movement of the first sliding seat 412 drives the transmission seat 42 to move synchronously.

[0041] The driving unit 41 further includes two second stoppers 414, which are distributed along the length direction of the first slide rail 411, and the transmission seat 42 is located between the two second stoppers 414;

[0042] The base 1 is fixedly provided with a second slide rail 7 and a second sliding seat 8. The second slide rail 7 is parallel to the sliding direction of the moving seat 2. The second slide rail 7 is fixedly provided on the base 1, and the second sliding seat 8 is installed on the second slide rail 7.

[0043] The movable seat 2 is provided with a support rod 9, one end of which is fixedly provided with a support block 10, and the support rod 9 is threadedly connected to the movable seat 2. When the rotating seat 3 is converted from an inclined state to a horizontal state, the bottom of the rotating seat 3 abuts against the top of the support block 10 to achieve support for the rotating seat 3. When the position of the support block 10 needs to be adjusted, the support rod 9 can be rotated;

[0044] The rotating seat 3 is fixedly provided with a baffle 11. When the chip 13 is tiltedly conveyed to the rotating seat 3, the baffle 11 supports the chip 13 to prevent the chip 13 from sliding off the rotating seat 3.

[0045] In summary, the translation and rotation of the rotating seat 3 are driven by the translation and rotation of the pin shaft 5, so as to realize the switching of the angle of the chip 13 on the rotating seat 3, reduce the volume, and save the operation space.
