In this embodiment, the angle and the number of turns of the first screw 22 driving the first screw 23 correspond to the distance that the first translation nut 24 moves correspondingly on the first screw 23. [0008] In order to better understand the present invention, the specific structure and the motion fit relationship of each component in the present invention will be described in detail below. Referring to FIG. 3 at the same time, the support portion 50 is formed along its length direction with a groove 51 which is open at both ends, and a symmetric 100100751 second guide 52 is disposed on both sides of the groove 51. Form No. 1010101 No. 5 1/Total Page !〇〇20〇1354-〇 201228768 [0010] The positioning machine 1 further includes a second positioning mechanism 30 placed in the recess 51. The second positioning mechanism 30 includes a second motor 31, a second coupling 32, a second positioning block 35, and a second screw rod fixedly connected between the second coupling 32 and the second positioning block 35. 33 and a second translation nut 34 movably coupled to the second lead screw 33. The second translation nut 34 abuts against the lower surface of the main board 2. When the user adjusts the main board 2 in the second direction, the second coupling 32 drives the second translation nut 34 to move back and forth by the second screw 33 under the action of the second motor 31, thereby driving the to-be-positioned The main board 2 is moved along the second rail 52 on the recess 51 to a preset position. [0011] The positioning machine 1 further includes a third positioning mechanism 40, which includes a third motor 41, a third coupling 42, a third positioning block 45, and a fixed connection to the third coupling 42. The third screw 43 is connected to the third positioning block 45 and the third translation nut 44 is movably connected to the third screw 43. The positioning machine 1 further includes a light blocking plate 60 movably connected to the third motor 41, a moving portion 70 disposed on the third translation nut 44, and a lower portion of the light blocking plate 60 and fixed to the moving portion 70. The photoelectric switch 80 and a detecting pin 90 vertically disposed at the moving portion 70 away from the photoelectric switch 80. In the present embodiment, the photoelectric switch 80 includes a transmitting end 81 for transmitting light and a receiving end 82 for receiving light transmitted from the transmitting end 81. When the receiving end 82 receives the light sent by the transmitting end 81, the photoelectric switch 80 generates a high level signal. When the receiving end 82 does not receive the light sent by the transmitting end 81, the photoelectric switch 80 generates a high level signal. Low level signal. [0012] Please refer to FIG. 4 at the same time, when the user needs to adjust the displacement of the main board 2 in the first direction and the second direction, when the main board 2 needs to be processed, the third coupling 100100751 form number A0101 page 6 / total On page 17 of 1002001354-0 201228768, the third translation nut 44 is moved back and forth by the third screw 43 under the action of the third motor 41, and the moving portion 70 is driven to move the photoelectric switch 80 back and forth on the third screw 43. . When the light sent by the transmitting end 81 of the photoelectric switch 80 on the moving portion 70 is not blocked by the light blocking plate 60, the receiving end 82 of the photoelectric switch 80 receives the light sent from the transmitting end 81 to generate a high electric signal to the third motor. 41. The third motor 41 continues to operate in accordance with the high level signal to urge the moving portion 70 to move toward the main board 2 until the probe 90 presses the main board 2. When the detecting needle 90 presses the main board 2 to a predetermined strength, the user adjusts the light blocking plate 60 so that it blocks the light sent by the transmitting end 81 of the photoelectric switch 80 f) - at this time, the receiving end 82 of the photoelectric switch 80 cannot receive The light sent to the transmitting end 81 is generated, so that a low level signal is generated to the third motor 41, and the third motor 41 stops working, thereby fixing the third translational armor 44 to the third screw rod 43 at a preset position. The probe 90 is caused to press the main board 2 with a predetermined force. After the probe pin 90 fixes the main board 2 to the preset position, the user can perform related processing operations on the main board 2. Q [〇〇13] The third positioning mechanism includes a base 46 fixed to the base 1 and two symmetrical third rails 47 fixedly disposed on the third motor 41 and the base 46. It passes through the moving portion 7 and is disposed in parallel with the third screw rod 43. The moving portion 7 is moved back and forth on the third rail 47 by the third translation nut 44. The probe 90 includes a contact portion 93, a detecting portion 91, and an elastic member 92 connecting the contact portion 93 and the detecting portion 91. When the contact portion 93 of the probe pin 9 presses the main plate 2, the elastic member 92 generates an elastic deformation. The detecting portion 91 determines the magnitude of the elastic force according to the elastic deformation of the elastic member 92, thereby confirming 100100751 Form No. A0101 1002001354-0 201228768 to determine the strength of the detecting pin 90 to press the main plate 2.
