[0024] Please refer to Figure 1 , which is a schematic diagram of a chip tray 200 cooperating with its turnover device 100 provided by an embodiment of the present utility model.
[0025] In one embodiment, the turnover device 100 of the chip tray (hereinafter referred to as the turnover device 100) is used to carry the chip tray 200 and drive the chip tray 200 to turn over. The turnover device 100 includes a first side wall 10 and a second side wall 20 arranged opposite to each other, and a third side wall 30 connecting the first side wall 10 and the second side wall 20. The first side wall 10, the second side wall 20, and the third side wall 30 enclose a receiving space 101 for receiving the chip tray 200.
[0026] Specifically, the first side wall 10, the second side wall 20, and the third side wall 30 enclose a "冂"-shaped receiving space 101 for the chip tray 200 to enter the receiving space 101 from front to back. The chip tray 200 includes a first side edge 201 and a second side edge 202 that are arranged opposite to each other and correspond to the first side wall 10 and the second side wall 20 respectively.
[0027] In one embodiment, the tray turning device 100 includes a rolling device 40 disposed on the first side wall 10 to abut against the first side edge 201 of the chip tray 200. In this way, the chip tray 200 rolls into the receiving space 101, and the first side edge 201 rolls against the rolling device 40, which has a smaller friction force, generates less fine chips and particles, and reduces the contamination of the chips by fine chips and tiny particles.
[0028] Specifically, at least two rolling devices 40 are disposed on the first side wall 10 along the front-rear direction, providing at least two rolling contact points, which is conducive to the chip tray 200 entering the receiving space 101 more smoothly.
[0029] In one embodiment, each of the rolling devices 40 includes a fixed shaft 41, and a rolling bearing 42 mounted on the fixed shaft 41 to abut against the chip tray 200. At least one rolling bearing 42 rotates around the fixed shaft 41 as a central axis, and the fixed shaft 41 is arranged along the height direction of the turning device 100, and a plurality of rolling bearings 42 are arranged in an array along the height direction. In this way, the first side edge 201 abuts against the outer peripheral surface of the rolling bearing 42 from front to back and enters the receiving space 101.
[0030] In one embodiment, the rolling device 40 includes a connecting spring 43, which has a fixed portion 431 connected to the first side wall 10, a floating portion 432 extending from the fixed portion 431 and connected to the fixed axis, and a floating space is formed between the floating portion 432 and the first side wall 10.
[0031] Specifically, the fixing portion 431 is attached to and fixed on the first side wall 10. The floating portion 432 can be elastically deformed to elastically abut against the first side edge 201. When the first side edge 201 abuts against the rolling bearing 42 and enters, the floating portion 432 is deformed toward the floating space by force, and the floating portion 432 generates an abutting force on the first side edge 201 close to the receiving space 101, so as to ensure that the chip tray 200 is subjected to a good clamping force in the receiving space to prevent it from sliding and falling when flipping.
[0032] In one embodiment, the floating portion 432 includes a vertical piece 433 arranged at an angle to the first side wall 10, and the vertical piece 433 extends obliquely from the fixed portion 431 toward the receiving space 101. In this way, when the first side edge 201 abuts against the rolling bearing 42, the vertical piece 433 can be deformed toward the first side wall 10 under force.
[0033] The angle between the vertical piece 433 and the first side wall 10 ranges from 20° to 45°. If the angle between the vertical piece 433 and the first side wall 10 is too large, it will affect the assembly of the chip tray 200, and if it is too small, it will not have a good elastic clamping effect. It can be seen that the angle formed by the vertical piece 433 and the fixing portion 431 is an obtuse angle, and the fixing shaft 41 is spaced apart from the vertical piece 433 and is located on the side away from the first side wall 10.
[0034] In one embodiment, the floating portion 432 includes a mounting piece 434 for fixing the fixed shaft 41, the mounting piece 434 is bent from the vertical piece 433 and extends horizontally, and a gasket 50 is arranged between the rolling bearing 42 and the mounting piece 434. The mounting piece 434 is formed by bending from both ends of the vertical piece 433 in the height direction, and both ends of the fixed shaft 41 are fixed to the mounting piece 434, and the rolling bearing 42 is arranged between the mounting pieces 434 in the height direction. If the rolling bearings 42 located on both sides in the height direction directly abut against the mounting piece 434, the wear is large when rolling. The gasket 50 can reduce the wear between the two and also reduce the generation of fine chips and particles.
[0035] In another embodiment, the floating portion 432 is an arc-shaped protrusion extending from the fixed portion 431 toward the receiving space 101, and the two fixed portions 431 are located at both ends of the arc-shaped protrusion. The fixed shaft 41 is disposed in the middle of the arc-shaped protrusion, which is also the highest point of the corresponding arc-shaped protrusion, to ensure a good elastic contact force. In other embodiments, the shape of the floating portion 432 is not limited, as long as it can be deformed to provide an elastic clamping force for the chip tray 200.
[0036] In one embodiment, the tipping device 100 includes a first bottom wall 11 and a first top wall 12 that cooperate with the first side wall 10, the first bottom wall 11 and / or the first top wall 12 are detachably arranged, and the first side edge 201 is located between the first bottom wall 11 and the first top wall 12.
[0037] Combination Figure 4 As shown, the first top wall 12 is fixed to the first side wall 10 by screws, which facilitates the installation and removal of the rolling device 30. The first bottom wall 11 and the first top wall 12 clamp the first side edge 201 along the height direction to clamp the chip tray 200 when turning over to prevent it from falling.
[0038] In one embodiment, the flipping device 100 includes an opening for the chip tray 100 to enter the receiving space 101, and the first side wall 10 is provided with a protruding wall 13 corresponding to the opening, and the protruding wall 13 has an arc surface 131 facing the receiving space 101, so as to guide the assembly of the chip tray 200.
[0039] The tray turning device 100 includes a rolling device 30 disposed on the second side wall 20 for rolling against the second side edge 202 of the chip tray. The rolling abutment is provided on both sides, which is conducive to balanced, stable and smooth entry into the receiving space 101.
[0040] The rolling device 30 of the second side wall 20 is consistent with the rolling device 30 of the first side wall 10. The rolling device 30 of the second side wall 20 may also not be provided with a connecting spring 43. The rolling bearing 42 is installed on the fixed shaft 41, and both ends of the fixed shaft 41 are directly fixed in the second side wall 20. It can be seen that a through groove for accommodating the rolling device 30 should be provided in the second side wall.
[0041] Similarly, the turning device 100 includes a second bottom wall 21 and a second top wall 22 that cooperate with the second side wall 20 , the second bottom wall 21 and / or the second top wall 22 are detachably arranged, and the second side edge 202 of the chip tray is located between the second bottom wall 21 and the second top wall 22 .
[0042] The second top wall 22 is fixed to the second side wall 20 by screws, which facilitates the installation and removal of the rolling device. The second bottom wall 21 and the second top wall 22 clamp the second side edge 202 along the height direction to clamp the chip tray 200 when turning it over to prevent it from falling.
[0043] In one embodiment, the inner wall surface of the third side wall 30 is provided with an anti-fouling surface 31 that cooperates with the chip tray 200. Figure 5 As shown, the fool-proof surface 31 is an angled surface. It can be understood that the corresponding corner of the chip tray 200 is cut off to form an angled angle. In this way, the angled angle cooperates with the angled surface to prevent the chip tray 200 from being inserted upside down.
[0044] The beneficial effects of the utility model are as follows: a rolling device 40 is provided on the first side wall 10, and the chip tray 200 rolls into the receiving space 101, with less friction and less generation of fine chips and particles; the two rolling devices 40 are arranged in an array along the front-to-back direction, which is conducive to smoother entry of the chip tray 200; the rolling device 40 is provided with a connecting spring 43 to provide an elastic clamping force for the chip tray 200.
[0045] It can be formed by referring to any of the technical solutions provided above, and will not be described in detail here.
[0046] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
