[0041] Optionally, the preset angle may be 360 ​​degrees. Each time the positioning rod 21 rotates one circle, the positioning assembly rotates to an area where positioning is possible. At this time, the fixture also moves to the area to position the fixture.

[0042] Optionally, the conveyor belt 11 is configured in a ring shape, and the transmission module 1 further includes a second driver, which is disposed at at least one end of the ring shape and connected to the conveyor belt 11 for driving the conveyor belt 11.

[0047] Optionally, the positioning device includes a conveyor frame, the conveyor belt 11 is arranged on the outside of the conveyor frame, and the first driver is fixed in the middle of the conveyor frame.

[0048] In one embodiment, the conveyor frame includes a first frame 141, a second frame 142, and at least one connecting frame 143. The first frame 141 and the second frame 142 are arranged in parallel, and the conveyor belt 11 is arranged on a side away from the first frame 141 and the second frame 142.

[0049] Optionally, the first fixing frame 141 and the second fixing frame 142 can have the same structure. The first fixing frame 141 includes a receiving member and a stopper. The receiving member is arranged along the length of the conveyor belt 11, and one side is provided with a receiving slot for accommodating the conveyor belt 11. The stopper is provided on both sides of the receiving member, with one side extending away from the receiving member and the other side being bent to form a baffle that partially covers the receiving slot to prevent the conveyor belt 11 from escaping the receiving slot. A reinforcement member for strengthening the first fixing frame 141 may also be provided on the side of the receiving member away from the receiving slot.

[0050] Optionally, the first drive includes a first drive motor 22, a first reducer 23 and a transmission mechanism 24. The first drive motor 22 and the first reducer 23 are fixed on the upper part of the conveying fixed frame. The first drive motor 22 is connected to the first reducer 23. The transmission mechanism 24 is respectively connected to the output end of the first reducer 23 and the positioning rod 21. The first drive motor 22 is used to drive the positioning rod 21 to rotate through the transmission mechanism 24.

[0051] Alternatively, the first drive motor 22 may be the same as the second drive motor 121, both being servo motors. The transmission mechanism may include a transmission belt, which is sleeved on the output end of the first drive motor 22 and the positioning rod 21, and the first drive motor 22 transmits power to the positioning rod 21 via the transmission belt.

[0052] In one embodiment, to protect the transmission belt, a protective shell may be provided on the outside of the transmission belt. The protective shell is sleeved on the transmission belt and covers the output end of the first drive motor 22 , and the positioning rod 21 passes through the protective shell.

[0053] Optionally, the positioning assembly includes a cam 25 having a first vertical plate, a second vertical plate, and a fixed ring. The fixed ring is mounted on the positioning rod 21. The first and second vertical plates are vertically fixed to the side of the fixed ring to form a slot for positioning the target fixture 3. A roller 35 is provided on the top of the target fixture 3. The width of the slot corresponds to the size of the roller 35. When the cam 25 rotates through a preset angle, the roller 35 moves to an area overlapping the slot, thereby accommodating the roller 35 through the rotation of the slot.

[0054] Optionally, multiple cams 25 can be positioned at the same location on the positioning rod 21. These cams 25 surround the positioning rod 21, and the angles formed by two adjacent cams 25 are the same. Each time the positioning rod 21 rotates through a predetermined angle, a cam 25 rotates to an area available for positioning the roller 35. Accordingly, at this time, a roller 35 of a jig enters the slot of the cam 25.

[0055] In one embodiment, the second drive motor 121 outputs power to the synchronous pulley 123 via the second reducer 122, thereby driving the conveyor belt 11. Because the synchronous pulley 123 has 60 teeth (with a tooth pitch of 10 mm), each rotation of the synchronous pulley 123 can move the jig 600 mm. The second drive motor 121 is a servo motor with a rated speed of 3000 rpm. The reduction ratio of the second reducer 122 is 10. According to calculations, the jig can move from rest to 600 mm and then stop in 0.7-0.8 seconds, thus achieving high-speed movement. The first drive motor 22 outputs power to the transmission mechanism 24 via the first reducer 23, driving the cam 25 to rotate. The first drive motor 22 and the second drive motor 121 work in conjunction, causing each rotation of the synchronous pulley 123 to coincide with a corresponding rotation of the cam 25 shaft. The meshing clearance between the cam 25 slot and the roller 35 is no greater than 0.06 mm. The jig is positioned by the cam 25 to ensure accurate stopping. When the jig starts to move, the cam 25 also rotates synchronously to separate from the cam 25 roller 35 on the jig. When the jig is transported to the limit area, the cam 25 just rotates synchronously to the limit area, allowing the roller 35 to enter the slot, thereby achieving high-precision positioning.

[0056] Optionally, to reduce the collision between the roller 35 and the slot and to reduce the difficulty of the roller 35 entering the slot, the roller 35 is cylindrical, and the first and second vertical plates are provided with arc surfaces matching the roller 35 on the opposite sides thereof. The middle portions of the first and second vertical plates are flat.

[0057] Optionally, in order to enable the roller 35 to contact the cam 25, the target fixture 3 also includes a carrier frame 36 and a first base plate 31. The carrier frame 36 is an I-shaped structure, and the roller 35 is fixed on the top of the carrier frame 36. The two ends of the I-shaped structure are fixed on the first base plate 31.

[0058] Optionally, the positioning assembly also includes a limiting member provided with a third vertical plate 26, a fourth vertical plate 27, a first flat plate 28, and a first base 29.

[0059] In one embodiment, the first base 29 is disposed between the first fixing frame 141 and the second fixing frame 142. The first base 29 includes a column and a second bottom plate. One end of the column is fixed to the second bottom plate, and the other end of the column extends above the first fixing frame 141 and the second fixing frame 142. Connecting frames 143 are provided at both ends of the column.

[0060] Optionally, in order to fix the cam 25 and the positioning column, a nut is provided on the side of the third vertical plate 26 and the fourth vertical plate 27 away from each other, and the nut is sleeved on the positioning rod 21 .

[0062] In one embodiment, a guide rail slider 34 is fixed to the side of the first base plate 31 away from the carrier 36. The target fixture 3 moves on the linear guide rail 13 via the guide rail slider 34.
