[0039] See also Figures 1 to 12 The tray conveying device includes a conveying mechanism, a transverse driving mechanism and a rotary clamping mechanism, wherein:

[0040] The material tray 7 is in the shape of a disk, and a center hole is opened in the middle of the material tray 7, and the center hole passes through the upper and lower ends of the material tray 7.

[0041] The conveying mechanism includes a conveying platform 1, an upper support plate 2, a lower support plate 3, and a longitudinal drive member 4. The conveying platform 1 is fixed, that is, the position of the conveying platform 1 remains unchanged; the conveying platform 1, the upper support plate 2, and the lower support plate 3 are arranged in sequence from top to bottom, that is, the conveying platform 1 is located above the upper support plate 2, and the upper support plate 2 is located above the lower support plate 3; the upper support plate 2 and the lower support plate 3 slide relative to each other through the guide column 11, that is, the upper support plate 2 can move along the guide column 11, and the guide column 11 is provided to ensure guidance so that lifting and lowering are smooth.

[0042] The upper surface of the conveyor platform 1 (the side away from the upper support plate 2) is a horizontal surface, which is used to place the material tray 7. The conveyor platform 1 is provided with a through hole 101 passing through the upper and lower surfaces thereof, and the through hole 101 extends in the horizontal direction.

[0043] See also Figure 12 The conveying platform 1 has an upper surface and an annular side surface perpendicular to the upper surface. The annular side surface is connected to the upper surface and surrounds a storage space with a bottom opening.

The clamping end of the clamping assembly can extend through the through-hole 101 to clamp the tray 7 on the conveyor platform 1. The rotary drive 605 is connected to the clamping assembly and drives the clamping assembly to rotate. When the clamping assembly clamps the tray 7, the rotary drive 605 drives the clamping assembly and the tray 7 to rotate until they reach the designated position. The purpose of rotation is that the tray 7 needs to be labeled, and the labeling position of each tray 7 held by the clamping assembly is not fixed. The tray 7 must be rotated to the designated position before it can be labeled. The provision of the rotary clamping mechanism 6 facilitates labeling of the tray 7.

[0048] The specific implementation of the tray conveying device for conveying the tray 7 is as follows:

[0049] S1, the material tray 7 is first located on the first material receiving station; the driving end of the longitudinal drive member 4 is in a descending state, and the transverse drive mechanism 13 drives the conveying mechanism to move to the far left, driving the rotary clamping mechanism 6 to move to the far left; at this time, the longitudinal drive member 4 drives the upper support plate 2 and the conveying guide rod 5 to rise, so that the conveying guide rod 5 is inserted into the center hole of the material tray 7; the transverse drive mechanism 13 at the bottom drives the conveying mechanism to move to the right, and then the longitudinal drive member 4 drives the conveying guide rod 5 to descend, and the electronic material tray 7 falls on the conveying platform 1. At this time, the material tray 7 moves from the first material receiving station to the second material receiving station, and then a new material tray 7 (the second piece) is placed on the first material receiving station;

[0050] S2. Repeat step S1, that is: the transverse drive mechanism 13 drives the conveying mechanism to move to the far left, driving the rotary clamping mechanism 6 to move to the far left; at this time, the longitudinal drive member 4 drives the upper support plate 2 and the conveying guide rod 5 to rise, so that the conveying guide rod 5 is inserted into the center hole of the second sheet material tray 7; the clamping end of the clamping assembly of the rotary clamping mechanism 6 extends into the center hole of the first sheet material tray 7 located at the second material receiving station, and then drives the clamping assembly and the material tray 7 to a specific position (specific angle); the transverse drive mechanism 13 then drives the conveying mechanism to move to the right, and the longitudinal drive member 4 drives the upper support plate 2 and the conveying guide rod 5 to descend, and the material tray 7 falls on the conveyor table 1. At this time, the first sheet material tray 7 moves from the second material receiving station to the third material receiving station, and the second sheet material tray 7 moves from the first material receiving station to the second material receiving station.

[0051] This cycle continues until the first sheet tray 7 is delivered to the fifth receiving station, thus completing the intermittent delivery step.

[0052] In some embodiments, the clamping assembly includes a clamping drive 603 and two clamping members. The two clamping members are horizontally and oppositely arranged. The two clamping members have the same structure. The upper end of the clamping member forms a clamping end. The upper end of the clamping member can extend out of the through hole 101 of the conveyor platform 1 to cooperate with the center hole of the material tray 7. The clamping drive 603 is used to drive the two clamping members to move toward or away from each other. When the two clamping members move toward each other, they can tighten the center hole wall of the material tray 7. When the two clamping members move away from each other, they can loosen the material tray 7.

[0053] The clamping member includes a slider 602 and a clamping rod 601. The slider 602 is connected to the clamping drive 603. The clamping rod 601 is mounted on the slider 602, and the clamping rods 601 of the two clamping members are arranged opposite each other. In this example, the two clamping rods 601 are combined to form a cylinder, and each clamping rod 601 is half of the cylinder (cut along the cylinder axis). The upper end of the clamping rod 601 has a pointed portion (the diameter of the tip gradually decreases from its lower end to the upper end), which facilitates the quick insertion of the clamping rod 601 into the center hole of the tray 7.

[0054] The clamping member also includes a support plate 604, which is arranged on the slider 602. The support plate 604 is provided with an avoidance hole for avoiding the clamping rod 601. The support plate 604 is semicircular. The two support plates 604 are combined to form a circular plate with a center hole. The support plate 604 is used to support the material tray 7 to prevent the material tray 7 from escaping from the clamping member.

[0055] See also Figure 10-11 The rotating driving member 605 is connected to the clamping assembly through the connecting member 10, that is, the driving end of the rotating driving member 605 is connected to the connecting member 10, and the clamping assembly is connected to the connecting member 10. The connecting member 10 includes a bottom plate and two side plates. The two side plates are both located on the upper side of the bottom plate. The side plates are perpendicular to the bottom plate. A gap is maintained between the two side plates. The two side plates are connected to the bottom plate in a U shape, and the clamping assembly is located in the U-shaped space of the connecting member 10.

[0056] The device also includes a sensor sheet, a sensor 8, and a controller. The sensor sheet is connected to a connector 10 (or a clamping assembly). Sensor 8 is positioned on the side of the upper support plate 2 away from the lower support plate 3 and is used to sense the sensor sheet. The controller is connected to both sensor 8 and the rotary drive 605. Sensor 8 can be an Omron slot-type photoelectric sensor 8.

[0057] In some embodiments, see Figure 11 The sensing piece includes a connecting portion 15 and a sensing portion 14 . The connecting portion 15 is connected to the connecting piece 10 . The sensing portion 14 is connected to the connecting portion 15 and is perpendicular to the connecting portion 15 . The sensing portion 14 is L-shaped. The sensor 8 is used to sense the sensing portion 14 of the sensing piece.

[0058] The device also includes a mounting base 9, and the sensor 8 is connected to the mounting base 9. A downwardly recessed groove is provided on the mounting base 9, and the front and rear sides of the groove are open. When the sensor sheet extends into the groove, the rotating drive member 605 stops driving, and the material tray 7 can be marked at this time. After the marking is completed, the rotating drive member 605 continues to drive the clamping assembly to rotate to the initial state.

[0059] The device also includes a reinforcing plate 12, which is located on the side of the upper support plate 2 away from the lower support plate 3. The reinforcing plate 12 is located between the conveyor platform 1 and the upper support plate 2. The reinforcing plate 12 is fixed in position. The upper end of the guide post 11 is connected to the reinforcing plate 12, and the lower end of the guide post 11 is connected to the lower support plate 3. The reinforcing plate 12 is provided with a through hole, and the connecting member 10 is partially located in the through hole.

[0060] In this example, both the upper support plate 2 and the lower support plate 3 are provided with openings. The main body of the rotating drive member 605 is fixedly connected to the bottom of the upper support plate 2, and the driving end of the rotating drive member 605 extends out of the opening on the upper support plate 2; the main body of the rotating drive member 605 passes through the opening on the lower support plate 3 to avoid the rotating drive member 605.
