Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic manufacturing, in particular to a tray hook transmission part, a tray and a metal tray. Background Art
[0002] In the process of manufacturing solar cells, a thin film needs to be formed on the silicon wafer through plasma chemical vapor deposition equipment. When depositing the thin film, the silicon wafer needs to be placed on the tray first, and then the tray is transferred. The way to transfer the tray is to use a cylindrical pin to push and pull the tray to move forward and backward. A tray hook with a diamond hole will be set on the side of the tray. The cylindrical pin will hook the limit hole on one side of the diamond hole before starting the transfer, and the tray will move under the drive of the cylindrical pin. Because the tray will be heated during transportation, the outer dimensions will change, and the relative position of the diamond hole and the hook claw will change, which may cause the tray to fail to be hooked and transferred.
[0003] The entire pallet is placed on the bearing roller for transmission, so the pallet can be pushed away with very little force. When the cylindrical pin enters the diamond hole, it is easy to push the pallet and cause the position to shift. When the transmission stops at the right position, the pallet will continue to rush forward under the action of inertia. Using a pallet hook with a diamond hole will cause the front and rear positions of the pallet to be inaccurate.
[0004] Therefore, how to provide a pallet hook transfer component and a pallet to improve the position deviation when starting to hook and transfer and when the hook is in place and improve the fault tolerance and accuracy of the pallet hook transfer positioning has become a technical problem that needs to be solved urgently in the industry. Summary of the invention
[0005] In view of the above-mentioned problems in the prior art, the utility model proposes a pallet hook transfer component, comprising a metal body, a central through hole arranged in the middle of the metal body, a first limiting hole and a second limiting hole arranged on both sides of the central through hole and connected thereto, and a plurality of elastic cantilevers arranged around the central through hole. The plurality of elastic cantilevers gradually converge along the direction from the middle of the central through hole to the first limiting hole or the second limiting hole, thereby providing elastic support and limiting the position after being in place in the process of the conveying hook tooth moving from the middle of the central through hole to the first limiting hole or the second limiting hole.
[0006] In one embodiment, each elastic cantilever includes a bent portion hollowed out on the metal body adjacent to the central through hole and a cantilever along the periphery of the central through hole and used to support or limit the conveying hook tooth, the bent portion is connected to the metal body, and the cantilever is connected to the bent portion.
[0007] In one embodiment, the multiple elastic cantilevers include a first elastic cantilever, a second elastic cantilever, a third elastic cantilever and a fourth elastic cantilever, and the first elastic cantilever, the second elastic cantilever, the third elastic cantilever and the fourth elastic cantilever respectively include a first cantilever, a second cantilever, a third cantilever and a fourth cantilever, and the first cantilever and the second cantilever are arranged in an eight-shape with their heads facing the first limiting hole, and the third cantilever and the fourth cantilever are arranged in an eight-shape with their heads facing the second limiting hole.
[0008] In one embodiment, the free end of the first cantilever and the free end of the second cantilever form an eight-shaped head facing the first limiting hole, and the distance between the two free ends is smaller than the size of the conveying hook tooth, so that the conveying hook tooth elastically deforms away when passing through and resets to limit after passing through, and the free end of the third cantilever and the free end of the fourth cantilever form an eight-shaped head facing the second limiting hole, and the distance between the two free ends is smaller than the size of the conveying hook tooth, so that the conveying hook tooth elastically deforms away when passing through and resets to limit after passing through.
[0009] In one embodiment, the middle through hole is a diamond-shaped through hole, and the first limiting hole and the second limiting hole are respectively located on both sides of two horizontal vertices of the diamond-shaped through hole and are both shaped to match the transmission hook teeth.
[0010] In one embodiment, the transmission hook tooth is a cylinder, and the first limiting hole and the second limiting hole are both matching cylindrical holes.
[0011] The utility model also discloses a pallet, which includes the pallet hook transmission member described in any one of the above items, wherein the pallet hook transmission member and the pallet are separate structures, a plurality of first mounting holes are opened on the metal body of the pallet hook transmission member, and a plurality of second mounting holes are correspondingly opened on the side wall of the pallet, and a plurality of fixing members respectively pass through the plurality of first mounting holes and the plurality of second mounting holes to fix the pallet hook transmission member on the side wall of the pallet.
[0012] In one embodiment, the tray is a metal tray or a carbon / carbon composite material tray.
[0013] The utility model further discloses a metal pallet, which comprises the pallet hook transmission member as described in any one of the above items, wherein the pallet hook transmission member is arranged on the side wall of the metal pallet and the two are integrally formed.
[0014] In one embodiment, the metal tray is an aluminum alloy tray, and the metal body is an aluminum alloy body.
[0015] Compared with the prior art in which the pallet hook conveyor only includes through holes, resulting in the displacement of the hook conveyor position and low hook conveyor positioning accuracy, the pallet hook conveyor of the utility model includes a metal body, a middle through hole arranged in the middle of the metal body, a first limiting hole and a second limiting hole arranged on both sides of the middle through hole and connected thereto, and a plurality of elastic cantilevers arranged around the middle through hole, wherein the plurality of elastic cantilevers gradually converge along the direction from the middle of the middle through hole to the first limiting hole or the second limiting hole, thereby providing elastic support and limiting the position of the conveying hook teeth when they move from the middle of the middle through hole to the first limiting hole or the second limiting hole.

[0028] Each elastic cantilever 14, 15, 16, 17 includes a bending portion 140, 150, 160, 170 which is hollowed out and arranged on the metal body 10 adjacent to the middle through hole 11, and a cantilever 142, 152, 162, 172 which is arranged along the periphery of the middle through hole 11 and is used to support or limit the conveying hook 2, the bending portion 140, 150, 160, 170 is connected to the metal body 10, and the cantilever 142, 152, 162, 172 is connected to the bending portion 140, 150, 160, 170. The bending portion 140, 150, 160, 170 is a bending structure similar to an N shape, and the elasticity of the elastic cantilever 14, 15, 16, 17 comes from its structure itself.
[0029] The multiple elastic cantilevers 14, 15, 16, 17 include a first elastic cantilever 14, a second elastic cantilever 15, a third elastic cantilever 16 and a fourth elastic cantilever 17, the first elastic cantilever 14, the second elastic cantilever 15, the third elastic cantilever 16 and the fourth elastic cantilever 17 respectively include a first cantilever 142, a second cantilever 152, a third cantilever 162 and a fourth cantilever 172, the first cantilever 142 and the second cantilever 152 are arranged in an eight-shape with their heads facing the first limiting hole 12, and the third cantilever 162 and the fourth cantilever 172 are arranged in an eight-shape with their heads facing the second limiting hole 13.
[0030] The free end 1420 of the first cantilever 142 and the free end 1520 of the second cantilever 152 form an eight-shaped head facing the first limiting hole 12, and the distance between the two free ends 1420, 1520 is smaller than the size of the transmission hook tooth 2, so that the transmission hook tooth 2 is elastically deformed and moved away when passing through, and resets to limit after passing through. The free end 1620 of the third cantilever 162 and the free end 1720 of the fourth cantilever 172 form an eight-shaped head facing the second limiting hole 13, and the distance between the two free ends 1620, 1720 is smaller than the size of the transmission hook tooth 2, so that the transmission hook tooth 2 is elastically deformed and moved away when passing through, and resets to limit after passing through.
[0031] When using Figure 1 as well as Figure 2 When the pallet hook conveyor 1 is shown, a plurality of fixing members 19 (see Figure 4 as well as Figure 5 ) through the plurality of first mounting holes 18 and the plurality of second mounting holes on the side wall of the pallet, so as to mount the pallet hook transmission member 1 on the side wall of the pallet, and then use the transmission hook teeth 2 to transmit the pallet.
