To meet these requirements, the chip tray loading and unloading mechanism often employs a multi-layer stacking method. Therefore, it is essential to solve the problem of how to achieve simple and reliable stacking of multi-layer trays to ensure efficient production. Utility Model Content

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] This utility model discloses a high-efficiency transport mechanism for chip trays. Four columns, arranged in pairs on both sides of the transport assembly, form a rectangular loading channel. Two push blocks are located on both sides of the transport assembly and can move into the loading channel. A carrier plate for contacting the tray is mounted on the movable base plate of the transport assembly. The carrier plate, which can move horizontally, can move between the two push blocks.

Detailed Implementation

[0025] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0026] Example 1: A high-efficiency transport mechanism for a chip tray includes: a transport component 5 extending horizontally, four columns 6 extending vertically, and push blocks 15 movable vertically. The four columns 6, arranged in pairs on both sides of the transport component 5, form a rectangular loading channel 14. The two push blocks 15 are located on both sides of the transport component 5 and can be moved into the loading channel 14. A carrier plate 4 for contacting the tray 100 is installed on the movable base plate 3 of the transport component 5. The carrier plate 4, which can be moved horizontally, can be moved between the two push blocks 15.

[0027] Two adjacent columns 6 each have a rotating shaft 7 installed facing each other on one side, and two other columns 6 each have a rotating shaft 7 mounted on one side. Each rotating shaft 7 has a rotatable stop block 8. An elastic element 9 is provided on the stop block 8 on the side of the rotating shaft 7 opposite to the feeding channel 14. One end of the elastic element 9 is connected to the stop block 8, and the other end extends upward and connects to the column 6. The stop block 8 has a bearing surface 101 for overlapping with the lower surface of the material tray 100 and a stop surface 102 located below the bearing surface 101 on the side of the rotating shaft 7 near the feeding channel 14. The stop surface 102 and the bearing surface 101 form an acute angle α. When the elastic element 9 is in a naturally relaxed state, the bearing surface 101 is in a horizontal position. When the stop surface 102 is in a vertical position, the elastic element 9 is in an extended state.

[0028] The aforementioned material handling assembly 5 further includes: a mounting housing 1 extending in a horizontal direction, a motor 2 mounted at one end of the mounting housing 1, and a lead screw rotatably mounted inside the mounting housing 1. The lead screw, one end of which is connected to the output shaft of the motor 2, is connected to the movable base plate 3 via a thread.

[0029] The two push blocks 15 mentioned above are installed on the movable part of a Z-axis drive assembly 16 and are located inside or directly below the feeding channel 14; the bearing surfaces 101 of the four stops 8 are respectively used to overlap and contact a corner of the lower surface of the tray 100.

[0030] Example 2: A high-efficiency transport mechanism for a chip tray includes: a transport component 5 extending horizontally, four columns 6 extending vertically, and push blocks 15 movable vertically. The four columns 6, arranged in pairs on both sides of the transport component 5, form a rectangular loading channel 14. The two push blocks 15 are located on both sides of the transport component 5 and can be moved into the loading channel 14. A carrier plate 4 for contacting the tray 100 is installed on the movable base plate 3 of the transport component 5. The carrier plate 4, which can be moved horizontally, can be moved between the two push blocks 15.

[0031] Two adjacent columns 6 each have a rotating shaft 7 installed facing each other on one side, and two other columns 6 each have a rotating shaft 7 mounted on one side. Each rotating shaft 7 has a rotatable stop block 8. An elastic element 9 is provided on the stop block 8 on the side of the rotating shaft 7 opposite to the feeding channel 14. One end of the elastic element 9 is connected to the stop block 8, and the other end extends upward and connects to the column 6. The stop block 8 has a bearing surface 101 for overlapping with the lower surface of the material tray 100 and a stop surface 102 located below the bearing surface 101 on the side of the rotating shaft 7 near the feeding channel 14. The stop surface 102 and the bearing surface 101 form an acute angle α. When the elastic element 9 is in a naturally relaxed state, the bearing surface 101 is in a horizontal position. When the stop surface 102 is in a vertical position, the elastic element 9 is in an extended state.

[0032] A first support pin 111 is installed on the end face of the aforementioned stop block 8 and located on the side opposite to the feeding channel 14 of the rotating shaft 7. One end of the aforementioned elastic member 9 is connected to the first support pin 111, and the other end of the aforementioned elastic member 9 is connected to the second support pin 112 located above the first support pin 111.

[0033] One end of the second support pin 112, which extends horizontally, is connected to the elastic member 9, and the other end is connected to the base 6 through a connecting block 12; when the stop surface 102 is in the vertical position, the first support pin 111 is parallel to the second support pin 112.

[0034] The aforementioned rotating shaft 7 is mounted on the side surface of the column 6 via a support frame 13; the aforementioned rotating shaft 7 is rotatably engaged with the support frame 13 and the stop block 8 is fixedly mounted on the rotating shaft 7, or the aforementioned rotating shaft 7 is fixedly mounted on the support frame 13 and the stop block 8 is rotatably fitted onto the rotating shaft 7.

[0035] The working principle is as follows:

[0036] Under normal conditions, the bearing surfaces of all four blocks are in a horizontal position;

[0037] First, the pallets to be stacked are transported to the push block driven by the Z-axis drive component via the carrier plate of the material conveying component, so that the pallets are located in the feeding channel surrounded by 4 columns or directly below the feeding channel.

[0038] Next, the Z-axis drive assembly drives the push block to lift and transport the material tray upwards. During the upward movement of the material tray, it first contacts the stop surfaces of each stop block and pushes the stop block to rotate until the stop surface on the stop block rotates to a vertical position. The elastic element is stretched and elongated as the stop block rotates. At this time, the stop surface of the stop block loses its blocking effect on the material tray.

[0039] The Z-axis drive assembly drives the push block to continue lifting and transporting the material tray upwards until it passes the stop block. At this point, the stop block, which has lost the force of the material tray, rotates in the opposite direction and resets under the reset force of the elastic element.

[0040] Then, the Z-axis drive assembly drives the push block to move the material tray downwards until its bottom surface contacts the bearing surface of the reset stop block in a horizontal position, thus achieving stable support for the material tray;

[0041] By repeating the above process, each tray is stacked with the tray above it as it is lifted upwards. Then, by moving the tray downwards, the bottom surface of the lowest tray is brought into contact with the bearing surface of the block, thus stacking multiple trays on the bearing surfaces of the four blocks in the feeding channel.

[0042] The specific control schemes for the aforementioned material handling components and Z-axis drive components can all be obtained through external purchases and fall within the scope of existing technology, so they will not be elaborated upon.

[0043] When using the aforementioned high-efficiency transport mechanism for chip trays, it can both transport the trays horizontally and, through the vertical movement of the trays in the loading channel and the reciprocating rotation of four blocks with bearing surfaces and stop surfaces, realize the lifting and stacking of multiple trays in the loading channel, facilitating the automated stacking of trays.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
