Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that in the description of the present invention, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0033] Example: Combination Figure 1 As shown, this embodiment discloses a continuous feeding device, including:

[0034] Rack 1, the rack 1 is provided with a cache position 11 and a working position 12. Figure 1 As shown, the rack has a certain height, the cache position 11 and the working position 12 are arranged up and down, and the cache position 11 is located at the bottom.

[0035] A supporting device 2 is provided between the cache position 11 and the working position 12. Figure 2 As shown, the supporting device 2 includes a support plate 21 for carrying the material 100, the support plate 21 is U-shaped, and two support members 211 are respectively arranged on two sides of the U-shaped support plate 21, and the four support members 211 are used to carry the material 100. The four support members 211 prop up the material 100, so that the material 100 and the support plate 21 form a certain distance.

[0036] Optionally, three support members 211 may be provided, and the three support members 211 may be dispersed on the two support plates 21 to form a triangle, which can also support and lift the material 100. If the material 100 is too large and heavy, more support members 211 may be provided to provide sufficient support points to prevent the material 100 from bending due to its own weight.

[0037] The support plate 21 is connected to a moving mechanism, and the moving mechanism includes a screw rod 22, the screw rod 22 is connected to a motor, the screw rod 22 is sleeved with a screw nut, and the support plate 21 and the screw nut are fixedly connected. A limit plate 23 is provided between the two sides of the U-shaped support plate 21, and the limit plate 23 is fixedly connected to the frame 1 to prevent the support plate 21 from rotating with the screw nut. By driving the screw rod 22 to rotate by the motor, the support plate 21 can be controlled to reciprocate between the cache position 11 and the working position 12.

[0038] Optionally, the moving mechanism may also be a motor combined with a track structure or other structure that can drive the support plate 21 to move.

[0039] Initially, the support plate 21 is located at the cache position 11, and the cache position 11 is provided with a loading device 3, such as Figure 3 As shown, the whole loading device 3 includes a first whole loading component and a second whole loading component. The first whole loading component can arrange the material 100 along a first direction, and the second whole loading component can arrange the material 100 along a second direction. The first whole loading component and the second whole loading component jointly adjust the position of the material 100 on the supporting device 2.

[0040] The first whole-carrying member includes two whole-carrying mechanisms arranged opposite to each other, and the whole-carrying mechanism includes a first track extending along the first direction, and the first track includes two slot plates 31 arranged in parallel, and each slot plate 31 is provided with a slide plate 32, and the two slide plates 32 are connected by a first push plate 35. The two slot plates 31 are connected to the bottom plate 33, and the bottom plate 33 is provided with a groove matching the slot plate 31, so that the bottom of the slide plate 32 is located in the groove. The bottom plate 33 is fixedly connected to the frame 1. The first driving member is fixedly connected to the bottom plate 33, and the first driving member includes a first cylinder 34, and the first push plate 35 is connected to the driving end of the first cylinder 34.

[0041] The first push plate 35 is driven by the first cylinder 34 to move along the first direction to adjust the position of the material 100 on the support plate 21 in the first direction. The two slide plates 32 cooperate with the two slot plates 31 to guide and avoid bending of the driving end of the first cylinder 34 due to excessive weight of the material 100.

[0042] The second whole carrier includes two second push plates 36, which are slidably connected to the first push plate 35, and the two second push plates 36 are arranged at both ends of the first push plate 35 along the first direction. The first push plate 35 is provided with connecting plates 351 perpendicular to the first direction at both ends of the first push plate 35 along the first direction, and the connecting plate 351 is provided with two spaced guide holes, and a guide shaft 371 is provided in the guide hole, and a guide rod 372 is inserted in the guide shaft 371, and the second push plate 36 is fixedly connected to the two guide rods 372. The first push plate 35 is also fixedly connected with a second driving member, and the second driving member includes a second cylinder 38. The connecting plate 351 is also provided with a driving hole, and the driving rod of the second cylinder 38 passes through the driving hole and is fixedly connected to the second push plate 36.

[0043] After the first whole carrier positions the material 100 along the first direction, the second whole carrier is actuated, and the second cylinder 38 drives the second push plate 36 to move along the second direction to adjust the position of the material 100 on the pallet 21 in the second direction, so that the material 100 reaches the preset position, meeting the requirements of the positioning and photographing device 4 to receive the material 100.

[0044] After the first whole carrier cooperates with the second whole carrier to adjust the material 100 into position, the motor drives the screw rod 22 to rotate to transfer the support plate 21 to the working position 12 .

[0045] The working position 12 is provided with a positioning and photographing device 4, such as Figure 4 As shown, the positioning and photographing device 4 includes two positioning plates 41 arranged opposite to each other. The positioning plates 41 are connected to a third driving member, and the third driving member can drive the two positioning plates 41 to move toward or away from each other.

[0046] Initially, the distance between the two positioning plates 41 is sufficient for the material 100 to pass through. When the moving mechanism moves the pallet 21 to the working position 12, the third driving member drives the two positioning plates 41 to approach each other, and the two positioning plates 41 are respectively inserted from the gap between the support member 211 and the pallet 21 to the bottom of the material 100. When the moving mechanism drives the pallet 21 to return to its position, the material 100 falls on the two positioning plates 41.

[0047] The positioning plate 41 is connected with a guide device, and the structure of the guide device is the same as the first track structure of the first whole carrier.

[0048] The positioning plate 41 is provided with a limiting member, such as Figure 5 As shown, the limiting member includes two L-shaped baffles 411, and the material 100 is located between the two baffles 411. The two baffles 411 can position the material 100 in the third direction. Figure 1 As shown, in this embodiment, the third direction and the second direction are in the same direction.

[0049] In another feasible embodiment, the material 100 is positioned by the baffle 411 in the third direction, and in the direction perpendicular to the third reverse direction, that is, between the two positioning plates 41, the material 100 can move within a certain range. That is, there is a movable space between the two positioning plates 41, and the movable space can prevent the positioning and loading device 4 from locking the material 100 and causing the material to be unable to be loaded. The range is 1mm to 2cm.

[0050] The positioning and mounting device 4 also includes a mounting member 42. Figure 4 , 6 As shown, the carrier 42 is disposed on both sides of the material 100 perpendicular to the third direction. The carrier 42 includes a fourth drive connected to the frame 1 and a pusher 422 connected to the fourth drive, and the fourth drive includes a fourth cylinder 421.

[0051] The mounting member 42 is used to further adjust the position of the material 100 so that the position of the material 100 always meets the loading standard. That is, each time a material 100 is loaded, the mounting member 42 will adjust the position of the remaining material 100.

[0052] This embodiment is used for loading semiconductor trays, which are devices for storing, transporting and protecting semiconductor wafers. The semiconductor tray is provided with an inclined portion relative to the position of the pusher head 422, and the inclined portion is inclined from the inside to the outside and from the top to the bottom. A sealing ring made of rubber material is sleeved on the pusher head 422. When loading, the fourth cylinder 421 will drive the pusher head 422 to squeeze the inclined portion, thereby preventing two adjacent materials from touching each other when loading.

[0053] It should be noted that the first driving member, the second driving member, the third driving member and the fourth driving member mentioned in the present application include driving devices such as cylinders or motors that can provide power.

[0054] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
