Between every two teeth, there is an alignment groove for aligning the crystal. The alignment grooves correspond to the crystal holders 445 one by one.

[0090] The teeth have a right-angled triangle structure.

[0091] For a SMD multi-head high-speed transfer machine, the working principle is as follows: The operator places the tray into the magazine box 11. By controlling the operation of the magazine motor 18, the lifting of the magazine box 11 is driven to facilitate the pick-up mechanism to pick up the trays level by level. By controlling the operation of the first translation motor 212, the translation of the first nut seat 214 is achieved. At the same time, by controlling the operation of the second translation motor 222, the movement of the second translation seat 227 is achieved, so as to achieve the purpose of driving the baking plate 233 to move. When the baking plate 233 moves to the lower part of the tray in the magazine mechanism, it stops working. At this time, the magazine box 11 descends, and the baking tray lifts the tray. Then, the first translation component 21 and the second translation component are controlled to retract to the initial position;

[0092] By controlling the upper movement motor 342 to further control the position of the upper pick-up mechanism, and then by the operation of the upper pick-up motor, the upper pick-up suction nozzle is controlled to lift and lower until it moves above the crystal of the tray. Then, the upper pick-up suction nozzle is controlled to suck the crystal. Under the operation of the upper movement motor 342, the crystal is placed on the variable-distance alignment mechanism. After the variable-distance alignment is completed, the lower movement motor 352 controls the lower pick-up mechanism to move above the variable-distance alignment mechanism. By controlling the lower pick-up suction nozzle to suck the crystal after the variable distance is completed, the sucked crystal is placed on the crystal variable-distance alignment component 46.

[0093] Adjust the spacing between the 8 crystal holders 445 according to the spacing of the crystals in the tray. In this embodiment, the crystal spacing is taken as 4.3 mm. The spacing between the crystals can also be other values, which is determined according to the size of the tray. Control the lifting cylinder 48 to make the lifting block 47 work. The lifting block 47 contacts the first left cam plate 441 and the first right cam plate, and drives the movement of other cam plates, finally fixing the spacing of the crystal holders 445 to 4.3 mm. Transport the crystals to the crystal holders 445 through the left pick-and-place mechanism 36. The alignment nozzle 446 adsorbs the crystals to prevent them from falling off. Then control the alignment motor 462 to turn on. The alignment motor 462 drives the alignment cam 463 to move. When the cam rotates to the maximum diameter, the first alignment piece 466 and the second alignment piece 467 separate, and place the crystal on the crystal holder 445. The alignment motor 462 continues to work. The alignment cam 463 rotates to the minimum radius. At this time, the first alignment piece 466 and the second alignment piece 467 close, and perform variable-spacing alignment positioning on the crystals according to the size of the alignment groove. In this embodiment, the alignment groove is taken as 5 mm. The spacing of the crystals changes from 4.3 mm to 5 mm. Then the right pick-and-place mechanism 37 sucks the crystals after the variable-spacing is completed and places them in the tray of the second magazine mechanism.

[0094] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
