[0037] See Figure 2 and Figure 4 The clamping block 23 includes a clamping portion 231, a first rotating connecting portion 232 and a second rotating connecting portion 233. The clamping portion 231 is vertically arranged at the top of one longitudinal side of the first rotating connecting portion 232, and the second rotating connecting portion 233 is vertically located at the bottom of the other longitudinal side of the first rotating connecting portion 232.

The clamping portion 231 is located in the limiting groove 241; the angle between the push rod end of the pneumatic push rod 22 and the longitudinal horizontal line is an acute angle.

[0038] See Figure 2 The transfer drive assembly 30 includes a driving gear 31, a transmission gear 32, a transmission toothed belt 33 and a transfer servo motor 34. The transfer servo motor 34 is installed on one longitudinal side of the box body 10 through a motor mounting seat 35, and the transmission gear 32 is rotatably installed on the transverse inner wall on the other longitudinal side. The drive gear 31 is axially connected to the output shaft of the transfer servo motor 34. The drive gear 31 and the transmission gear 32 are synchronously rotated and connected through the transmission toothed belt 33. A toothed belt connector 36 is installed on the transmission toothed belt 33. An adapter 37 is installed on the sliding plate 21, and the adapter 37 is fixedly connected to the toothed belt connector 36.

[0039] A set of pallet lifting components 40 are respectively installed in the pallet upper plate area A and the pallet lower plate area C of the box body 10. The two sets of pallet lifting components 40 can carry the pallet to move up and down in the corresponding pallet upper plate area A and the pallet lower plate area C; see Figure 5 The tray lifting assembly 40 includes a tray supporting plate 41, a stepping motor 42 and a pair of column guide rails 43. The two longitudinal ends of the bottom of the tray supporting plate 41 are respectively vertically fixed with support plates 44. The stepping motor 42 is longitudinally mounted on the bottom plate of the box body 10 through a motor mounting plate 45. The bottom of the tray supporting plate 41 is transmission-connected to the stepping motor 42 through a cam connecting rod structure. The support plates 44 at the two longitudinal ends of the tray supporting plate 41 are respectively slidably mounted on the pair of column guide rails 43 through vertical sliders 46.

[0040] The cam-link structure includes a cam member 47, a connecting rod 48 and a carrier plate connecting member 49. The carrier plate connecting member 49 is fixed to the center of the bottom surface of the tray carrier plate 41. The cam member 47 has a first shaft hole 471 and a second shaft hole 472 that are both longitudinally straight. Figure 6 The output shaft of the stepper motor 42 extends into the first shaft hole 471 and is tightly connected to the cam member 47 . One end of the second connecting rod 472 is connected to the second shaft hole 472 via the first rotating shaft 410 , and the other end is connected to the supporting plate connecting member 49 via the second rotating shaft 411 .

[0041] The box body 10 is also provided with an automatic tray placement assembly on both lateral walls located in the upper tray area A of the tray. The automatic tray placement assembly includes two pallets 51. The longitudinal outer ends of the two pairs of tray limiting columns 11 and 12 in the upper tray area A of the tray are respectively provided with a cross beam box 52, and the two ends of the cross beam box 52 are respectively fixed to the top of the lateral side walls of the box body 10. Figure 1 and Figure 7 A groove 53 is symmetrically provided on the bottom of the side wall of the two beam boxes 52 facing each other. A support plate 51 is installed in each beam box 52 and the support plate 51 can extend out of the beam box 52 or retract into the beam box 52 along the longitudinal direction from the groove 53.

[0042] Each crossbeam box 52 is equipped with a cylinder 54. Figure 8 A group of longitudinal guide rails 55 are respectively arranged on both lateral sides of the cylinder 54. The guide rod of the cylinder 54 is fixedly connected to the support plate 51 in the crossbeam box 52 through a connecting piece 56, and the support plate 51 is slidably connected to the longitudinal guide rails 55 through a longitudinal sliding block 57.

[0043] When the cylinders 54 in the two beam boxes 52 are pushed out toward each other, the two support plates 51 are extended from the grooves 53 of their respective beam boxes 52. At this time, the longitudinal front and rear ends of the stacked chip trays loaded with chips are supported by the two support plates 51 in the tray upper plate area A on the box body 10 respectively; when the chip tray upper plate operation is required, first the stepper motor 42 of the tray lifting assembly in the tray upper plate area A is actuated and the cam connecting rod structure thereof is used to push the tray carrier plate 41 to move vertically upward along the column guide rail 43 until the tray carrier plate 41 contacts the bottom surface of the stacked chip trays, and then the guide rods of the cylinders 54 in the two beam boxes 52 are returned to the upper plate area A at the same time. The two support plates 51 are retracted into the corresponding cross beam boxes 52, so that the stacked chip trays are completely supported by the tray support plate 41, and then the stepper motor 42 is activated and drives the tray support plate 41 to move down by the thickness of a chip tray through the cam connecting rod structure, and the cylinders 54 in the two cross beam boxes 52 are activated at the same time to make the guide rods extend from the grooves 53 to the bottom of the longitudinal ends of the second to last chip tray, so that the chip tray at the bottom is supported by the tray support plate 41, while the chip trays stacked above are still supported by the two support plates 51 from both longitudinal sides; thus, the stacked chip trays are automatically dropped in sequence from bottom to top.

[0044] The box body 10 is also provided with an automatic tray receiving support assembly 60 on both lateral side walls of the tray lower tray area C. Figure 1 and Figure 2 The automatic tray receiving support assembly 60 includes at least two pairs of support seats 61 arranged in sequence in the lower tray area C along the longitudinal direction. Each pair of support seats 61 is symmetrically installed on the two lateral walls of the box body 10. Each support seat 61 has a concave cavity 62 that opens toward the inner side of the box body and is horizontally concave inwardly along the lateral direction. Figures 9 to 11The lateral inner cavity wall of the concave cavity 62 also has a continuous upper limiting step surface 63 and a lower limiting step surface 64. A flippable rotating support plate 66 is installed on the two longitudinal side walls of the concave cavity 62 of each support seat 61 through a third rotating shaft 65. The end of the rotating support plate 66 facing the inner side of the box body 10 is an oblique wedge-shaped structure with a flat top surface 661 and an inclined bottom surface 662, and the end facing the inner side of the concave cavity 62 has a flip positioning portion 663 protruding horizontally along the lateral direction. The flip positioning portion 663 of the rotating support plate 66 is limited by the lower limiting step surface 64. In the natural state, the flip positioning portion 663 of the rotating support plate abuts against the top surface of the lower limiting step surface 64. At this time, the entire rotating support plate 66 is in a horizontal state and the rotating support plate 66 protrudes from the end surface of one side of the support seat 61 facing the inner side of the box body 10; when the empty chip tray is moved to the tray lower plate area C by the longitudinal transfer mechanism and placed on the tray supporting plate 41 of the tray lifting assembly 40 in the tray lower plate area C, the stepper motor 42 of the tray lifting assembly 40 in the tray lower plate area C is actuated and pushes the tray supporting plate 41 to rise along the column guide rail 43 through its cam connecting rod structure. During the rising process, the lateral sides of the empty chip tray supported by the tray supporting plate 41 are gradually lifted. The stepper motor 42 gradually contacts the inclined surfaces at the bottom of the rotating support plates 66 on both sides and pushes the rotating support plates 66 to flip upward and open until the lateral ends of the empty chip tray pass over the rotating support plates 66. The stepper motor 42 then reverses and drives the tray supporting plate 41 to descend through the cam connecting rod structure. The empty chip tray descends under the action of its own weight after losing the support of the tray supporting plate 41. The four rotating support plates 66 flip downward at the same time under the action of the descending tray supporting plate 41 until the flip positioning portion 663 of the rotating support plate 66 abuts against the top surface of the lower limiting step surface 64. The empty chip tray is then supported by the four rotating support plates 66, thereby completing the automatic material receiving operation of an empty chip tray.

[0045] When the chip tray needs to be moved from the tray upper plate area A to the chip loading area B or the chip tray needs to be transported from the chip loading area B to the tray lower plate area C, the tray clamping assemblies 20 arranged on the two lateral side walls of the box body 10 act simultaneously, and the guide rods of the pneumatic push rods 22 of the two clamping units of each tray clamping assembly 20 are extended to push the correspondingly connected entire clamping blocks 23 to rotate in their respective limiting grooves 24, and rotate until the clamping portion 231 is limited by the longitudinal limiting end face of the limiting groove 24. At this time, the clamping blocks 23 of the two clamping units clamp the tray from both longitudinal ends. Then the stepper motor 42 of the tray lifting assembly 40 in the corresponding area is activated and the tray supporting plate 41 is moved down through the cam connecting rod structure to release the supporting effect of the tray supporting plate 41 on the tray. Then the transfer servo motor 34 is rotated to activate the driving gear 31, the transmission toothed belt 33 and the transmission gear 32. The transmission toothed belt 33 drives the sliding plate 21 to move longitudinally along the longitudinal slide rail 25 through the toothed belt connector 36. Thus, the two groups of clamping units installed on the sliding plate 21 clamp the chip tray and move longitudinally with the sliding plate 21 until it moves to the target area.

[0046] The above detailed description of the specific implementation of the present invention is only a preferred implementation of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
