Description

Technical Field

[0001] The utility model relates to the technical field of material tray transmission, in particular to a material tray conveying mechanism. Background Art

[0002] With the rapid development of the semiconductor industry, the production of semiconductor chips is gradually moving towards automation and standardization. In the process of chip production, chips are mostly loaded on trays. In order to improve efficiency, multiple trays are usually stacked and transported. When they are transferred to a certain workstation, the stacked trays are unstacked by the unstacking mechanism, and then the single tray is transported to the processing position by the conveying mechanism. However, the existing conveying mechanism is not designed reasonably. The time it takes for the conveying mechanism to rotate from the processing position to the unstacking mechanism is relatively long, and it is difficult to remove the unstacking single tray in time, resulting in low overall work efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a material tray conveying mechanism, which improves the conveying efficiency of the material tray, so as to facilitate the unstacking speed of the unstacking mechanism, thereby improving the overall work efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a tray conveying mechanism, comprising

[0005] A conveyor frame, one end of which along the conveying direction of the tray is provided with a stacking mechanism, and the other end is provided with a processing station; the conveyor frame is provided with a conveying track for receiving the tray;

[0006] There are two groups of conveying components, and the two groups of conveying components are arranged on both sides of the conveying frame perpendicular to the conveying direction of the material tray;

[0007] The pusher assembly is arranged one by one corresponding to the conveyor assembly, and can reciprocate between the unpacking mechanism and the processing station under the action of the corresponding conveyor assembly; and the two pusher assemblies are staggered along the conveying direction of the material tray to push different material trays to move respectively.

[0008] The beneficial effects of the tray conveying mechanism of the utility model are:

[0009] A conveying track is arranged on the conveying frame to guide the movement of the material tray from the destacking mechanism to the processing station; two sets of conveying components are arranged on both sides of the conveying frame to ensure the independent conveyance of the two sets of pushing components by the two sets of conveying components, so as to realize the independent conveyance of different material trays; since the positions of the destacking mechanism and the processing station are fixed, the travel path between the two is also fixed. Therefore, when the two pushing components are staggered along the conveying direction of the material tray, the time points when the pushing components move to the destacking mechanism are different, and then the time difference formed by the staggered can be used to realize that one pushing component drives the material tray to move to the processing station while the other pushing component rotates to the destacking mechanism to wait for the next destacking material tray; so as to improve the overall conveying efficiency of the material tray.

[0010] Further, the pusher assembly includes a pusher base plate, which is connected to the corresponding conveying assembly; a pusher rod capable of lifting and moving under the action of a lifting drive member is provided on the side of the pusher base plate away from the processing station; when the pusher rod is at the highest point, the pusher rod can abut against the material tray, and when the pusher rod is at the lowest point, the pusher rod is located below the material tray. The lifting and lowering movement of the pusher rod is used to facilitate the conveying of the material tray to the processing station, and the pusher rod can be located at the highest point to push the material tray to move, and when rotating to the unpacking mechanism, the pusher rod can be located at the lowest point to avoid touching the conveying material tray during the rotation process.

[0011] Furthermore, a stop assembly is provided on the side of the push substrate facing the processing station, and the stop assembly includes a stop plate that can abut against the tray under the action of the stop drive. Since the two groups of push assemblies are respectively located on both sides of the frame, in order to avoid interference between the two groups of push assemblies, the abutment point of the push rod against the tray is bound to be biased towards the side of the tray, and pushing the tray from the side of the tray may cause the tray to deflect due to uneven force. Therefore, a stop assembly is provided on the side of the push substrate facing the processing station, which can cooperate with the push rod to limit the two sides of the tray, thereby ensuring the stability of the tray during transportation.

[0012] Furthermore, the stop assembly also includes a hinged seat fixed to the pushing base plate, and the hinged seat is hinged with a stop plate through a pin shaft; the stop drive component includes a stop cylinder arranged in a horizontal direction, the piston rod of the stop cylinder faces the stop plate, and when the piston rod is extended, the piston rod can push the stop plate to flip over and abut against the material tray.

[0013] Furthermore, the stop assembly also includes a torsion spring sleeved on the pin shaft, one end of the torsion spring is connected to the stop plate, and the other end is connected to the hinge seat; when the torsion spring is in a natural state, the stop plate does not abut against the material tray. When the stop plate is flipped to abut against the material tray under the action of the stop cylinder, the torsion spring is in a stretched and deformed state; when the stop cylinder retracts, the torsion spring can drive the stop plate to return to the initial position (i.e., the position not abutting against the material tray).

[0014] Furthermore, the conveyor frame is also provided with guide rails corresponding to the pusher substrates, the guide rails are arranged along the conveying direction of the material tray, and the pusher substrates are slidably arranged on the corresponding guide rails. The guide rails guide the pusher substrates to further improve the stability of the pusher substrates, thereby facilitating the contact stability of the push rod and the stop plate with the material tray.

[0015] Furthermore, the conveyor frame includes two vertical plates arranged opposite to each other, and receiving plates are symmetrically arranged at the upper ends of the two vertical plates, and the receiving plates are provided with conveying tracks.

[0016] Furthermore, the vertical plate is provided with a plurality of limit blocks located above the conveying track along the conveying direction of the material tray, and a gap is left between the limit blocks and the conveying track for the material tray to pass through. The setting of the plurality of limit blocks can limit the moving material tray to prevent the material tray from slipping off the conveying track.

[0017] Furthermore, the conveying assembly includes a first transmission wheel and a second transmission wheel arranged at both ends of the conveying frame along the conveying direction of the material tray. A transmission belt is commonly wound around the first transmission wheel and the second transmission wheel, and the transmission belt is connected to the pushing assembly.

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] Example

[0031] See attached Figure 1-2 As shown, a tray conveying mechanism of the utility model comprises a conveying frame 1, a conveying assembly 2, and a pushing assembly 3, wherein a destacking mechanism 5 is provided at one end of the conveying frame 1 along the conveying direction of the tray 4, a processing station is provided at the other end, and a conveying track 11 for receiving the tray 4 is provided on the conveying frame 1. Two groups of conveying assemblies 2 are provided, and the two groups of conveying assemblies 2 are arranged on both sides of the conveying frame 1 perpendicular to the conveying direction of the tray 4. The pushing assembly 3 is arranged in a one-to-one correspondence with the conveying assembly 2, and can reciprocate between the destacking mechanism 5 and the processing station under the action of the corresponding conveying assembly 2. And the two pushing assemblies 3 are staggered along the conveying direction of the tray 4 to push different trays 4 to move respectively.

[0032] In the prior art, the stacking mechanism 5 usually splits the stacked material trays 4 and places the split single material trays 4 on the conveying track 11; then the pushing assembly 3 moves to the position close to the stacking mechanism 5 under the action of the corresponding conveying assembly 2, and the pushing assembly 3 can push the single material tray 4 on the conveying track 11, and then under the continued action of the conveying assembly 2, the pushing assembly 3 can drive the single material tray 4 to move in the direction of the processing station; when the material tray 4 moves to the processing station, the pushing assembly 3 rotates back to the stacking mechanism 5 to perform the next pushing action. However, since the time period for the pushing assembly 3 to move from the stacking mechanism 5 to the processing station and then rotate back to the stacking mechanism 5 is relatively long, and the stacking mechanism 5 needs to wait for the stacked material tray 4 to be taken away before performing the next stacking action, this affects the stacking speed of the stacking mechanism 5. Therefore, in this embodiment, independent transmission of different material trays 4 can be achieved through the cooperation of two groups of conveying components 2 and two groups of pushing components 3, and the two pushing components 3 are staggered so that while one pushing component 3 drives the material tray 4 to move toward the processing station, the other pushing component 3 rotates to the destacking mechanism 5 to wait for the next destacking material tray 3, so as to adapt to the destacking speed of the destacking mechanism 5 and improve the overall work efficiency.

[0033] In some embodiments, see Appendix Figure 3-4As shown, the material pushing assembly 3 includes a material pushing base plate 31, which is connected to the corresponding conveying assembly 2; a push rod 33 capable of lifting and moving under the action of a lifting drive member 32 is provided on the side of the material pushing base plate 31 away from the processing station; when the push rod 33 is at the highest point, the push rod 33 can abut against the material tray 4, and when the push rod 33 is at the lowest point, the push rod 33 is located below the material tray 4. The lifting and lowering movement of the push rod 33 is used to facilitate the conveying of the material tray 4 to the processing station, so that the push rod 33 can be located at the highest point to push the material tray 4 to move, and when rotating to the unpacking mechanism 5, the push rod 33 can be located at the lowest point to avoid touching the conveying material tray 4 during the rotation process.

[0034] Since the two groups of pushing components 3 are respectively located on both sides of the conveyor frame 1, in order to avoid interference between the two groups of pushing components 3, the contact point of the push rod 33 with the material tray 4 is bound to be biased to the side of the material tray 4, and pushing the material tray 4 from the side of the material tray 4 may cause the material tray 4 to deflect due to uneven force. Therefore, in some embodiments, a stop component is provided on the side of the pushing substrate 31 facing the processing station, and the stop component includes a stop plate 61 that can abut against the material tray 4 under the action of the stop drive. The stop component is provided on the side of the pushing substrate 31 facing the processing station, which can cooperate with the push rod 33 to achieve the limit of the two sides of the material tray 4, thereby ensuring the stability of the material tray 4 during the conveying process.

[0035] For further information, see Appendix Figure 4 As shown, the stop assembly also includes an articulated seat 62 fixed to the material pushing base plate 31, and the articulated seat 62 is articulated with the stop plate 61 through a pin. The stop driving member includes a stop cylinder 63 arranged in the horizontal direction, the stop cylinder 63 is installed on the material pushing base plate 31, and the piston rod of the stop cylinder 63 faces the stop plate 61. Furthermore, a torsion spring is sleeved on the pin, one end of the torsion spring is connected to the stop plate 61, and the other end is connected to the articulated seat 62.

[0036] When the torsion spring is in a natural state, the stop plate 61 does not abut against the material tray 4. At this time, the piston rod of the stop cylinder 63 is in a retracted state; when the piston rod of the stop cylinder 63 is extended, the piston rod can push the stop plate 61 to flip over and abut against the material tray 4. At this time, the torsion spring is in a tensile deformation state.

[0037] In some embodiments, see Appendix Figure 2 As shown, the conveying assembly 2 includes a first transmission wheel 21 and a second transmission wheel 22 arranged at both ends of the conveying frame 1 along the conveying direction of the material tray 4, and a transmission belt 23 is wound around the first transmission wheel 21 and the second transmission wheel 22. The first transmission wheel 21 is connected to the transmission motor 24, and the transmission belt 23 is connected to the pusher substrate 31. The cooperation of the first transmission wheel 21, the second transmission wheel 22 and the transmission belt 23 realizes the reciprocating transmission of the pusher substrate 31 between the destacking mechanism 5 and the processing station.

[0038] In some embodiments, the conveyor frame 1 is further provided with guide rails 12 corresponding to the material pushing substrates 31. The guide rails 12 are arranged along the conveying direction of the material tray 4, and the material pushing substrates 31 are slidably arranged on the corresponding guide rails 12. The guiding of the material pushing substrates 31 by the guide rails 12 further improves the stability of the movement of the material pushing substrates 31, thereby facilitating the improvement of the contact stability of the push rod 33 and the stop plate 61 with the material tray 4.

[0039] In some embodiments, see Appendix Figure 2 As shown, the conveyor frame 1 includes two vertical plates arranged opposite to each other, and receiving plates 13 are symmetrically arranged at the upper ends of the two vertical plates, and a conveying track 11 is arranged on the receiving plates 13. Furthermore, the vertical plates are provided with a plurality of limit blocks 14 located above the conveying track 11 along the conveying direction of the material tray 4, and a spacing for the material tray 4 to pass is left between the limit blocks 14 and the conveying track 11. The provision of a plurality of limit blocks 14 can limit the moving material tray 4 to prevent the material tray 4 from slipping off from above the conveying track 11.

It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
