[0032] Furthermore, the terms “comprising,” “having,” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may also include other steps or units that are not expressly listed but are inherent to these processes, methods, products, or apparatuses, or steps or units added based on further optimizations of the inventive concept.

[0033] like Figures 1-4 As shown, this invention discloses a product silo, which includes multiple silo units 1;

[0034] Each of the hopper units 1 includes a support plate 101 and a support rod 102 fixed at the corner of the support plate 101. The top of the support plate 101 is provided with several sets of positioning plates 2. Each set of positioning plates 2 includes two positioning plates 2. A sliding rod 3 is fixedly connected between two adjacent support rods 102 along the setting direction of the positioning plates 2. Several positioning plates 2 are sleeved on the sliding rod 3, and the positioning plates 2 are slidably connected to the sliding rod 3. On the side of the two positioning plates 2 in the same set that are close to each other, a set of positioning rods 4 is provided. Each set of positioning rods 4 includes two parallel positioning rods 4.

[0035] An adjustment limiting mechanism 5 is provided between several of the positioning plates 2 groups to adjust the distance between the two positioning plates 2 in each group;

[0036] The two support plates 101 of two adjacent silo units 1 share a support rod 102 on the connected side.

[0037] In this embodiment, the support plate 101 is a cuboid structure, and there are four support rods 102, which are fixed at the four corners of the support plate 101 respectively. When two adjacent hopper units 1 are fixed, the two support rods 102 are shared on the side where the two support plates 101 are joined.

[0038] The two positioning plates 2 of the aforementioned positioning plate group 2 are arranged in parallel, and the positioning rods 4 are arranged on the side that are close to each other. Each group of positioning rods 4 includes two parallel cylindrical positioning rods 4, and the positions of the positioning rods 4 on the two positioning plates 2 of each group are corresponding, that is, symmetrically arranged. When the product part is placed between the two positioning plates 2, its corners can be limited by the two positioning rods 4. The two opposing positioning rods 4 can position it from two directions. The positioning plates 2 fix the product part in the front-back direction, and the positioning rods 4 on both sides position the product part in the left-right direction.

[0039] like Figures 1-4As shown, the adjusting and limiting mechanism 5 includes a screw 51, which passes through several positioning plates 2 and is threadedly connected to the positioning plates 2;

[0040] The screw 51 is composed of several segments of double-ended studs connected end to end, and each segment of double-ended studs corresponds to a set of positioning plates 2. The double-ended studs are threadedly connected to the two positioning plates 2 of each set of positioning plates 2. When the screw 51 is rotated, the two positioning plates 2 of each set of positioning plates 2 slide in opposite directions or towards each other along the slide bar 3. A handwheel 52 is fixedly connected to one end of the screw 51.

[0041] The aforementioned screw 51 is composed of multiple double-ended studs connected end to end, and each double-ended stud corresponds to a set of positioning plates 2. The two positioning plates 2 of each set of positioning plates 2 are connected to the opposite ends of the threads of the double-ended stud. Thus, when the double-ended stud rotates, the two positioning plates 2 of each set of positioning plates 2 slide on the slide bar 3 in different directions (towards or in opposite directions), thereby adjusting the distance between the two positioning plates 2 according to the size of different product parts.

[0042] The bottom of the support plate 101 is provided with a plurality of top rods 6, the top rods 6 penetrate through the bottom of the support plate 101, and each top rod 6 corresponds to two corresponding positioning rods 4 of a positioning plate 2 group;

[0043] A top plate 7 is provided at the bottom of the top rod 6, and several top rods 6 are fixedly connected to the top plate 7. A bottom plate 8 is provided below the top plate 7, and the bottom plate 8 is fixedly connected to several support rods 102. A motor 9 is fixedly connected to the bottom of the bottom plate 8, and the output section of the motor 9 passes through the bottom plate 8. A lead screw 10 is rotatably connected to the bottom plate 8, and the lead screw 10 is fixedly connected to the output end of the motor 9. The other end of the lead screw 10 is rotatably connected to the bottom of the support plate 101. The lead screw 10 passes through the top plate 7, and the lead screw 10 is threadedly connected to the top plate 7. A guide rod 11 is inserted through the top plate 7, and the bottom of the guide rod 11 is fixedly connected to the bottom plate 8, and the top of the guide rod 11 is fixedly connected to the support plate 101.

[0044] The aforementioned push rod 6 is installed at the bottom of the support plate 101. When the motor 9 drives the lead screw 10 to rotate, the lead screw 10 can drive the top plate 7, which is threaded to it, to move up and down. The top plate 7 drives the push rod 6 to move up and down along the support plate 101. Each push rod 6 corresponds to a set of two positioning rods 4. After the suction cup grabs the product part, the motor 9 drives the push rod 6 to move upward, pushing the product part positioned in the positioning rods 4 upward, so that the suction cup can grab the part.

[0045] The aforementioned guide rod 11 can guide and position the top plate 7 when the lead screw 10 rotates, so that the top plate 7 does not rotate with the lead screw 10, thereby achieving lifting and lowering when the lead screw 10 rotates, driving the top rod 6 to move upward through the bottom of the support plate 101, and lifting the product parts between the two positioning plates 2 and the positioning rod 4 on the support plate 101.

[0046] An air nozzle is installed on the positioning plate 2. The air nozzle is connected to an external air source. The position of the air nozzle corresponds to that of the positioning rod 4. The nozzle nozzle is positioned directly above the product part from the side.

[0047] Compressed air is used to blow air through the product during the gripping process to prevent the product from gripping two or more pieces.

[0048] This invention utilizes the characteristics of the product's shape, changing the positioning method to diagonal positioning. When the product's shape and size are different, the adjusting and limiting mechanism 5 on the positioning plate 2 is used to adjust the distance between the two sides of the positioning plate 2, so that the product is tightened diagonally. This positioning will position the product in two directions, preventing the product from moving around. At the same time, the hopper adopts an independent external structure, using a square profile frame for positioning. The middle is divided into 4 groups of positioning plates 2, and the whole is positioned by the positioning plates 2. Two screws 51 are installed at the top and bottom of the middle for fixation. When it is necessary to adjust the distance between the positioning plates 2, the handwheel 52 on the end face of the screw 51 is rotated to achieve diagonal adjustment of the product. 4 sets of top rods 6 are installed at the bottom of the hopper. When the product is grabbed, the bottom top rods 6 will move upward, driving the product in the hopper to move upward by 30mm. When the product is grabbed by the suction cup, the bottom top rods 6 will descend to the original position. Using program control, as products are successively grabbed, the bottom top cover will gradually increase its movement distance.

[0049] Using the overall front and rear positioning plates 2, cylindrical positioning rods 4 are installed on them. The curved surface allows the product to be positioned diagonally, so that the product can be positioned in both directions. Two screws 51 can be used to make precise micro-adjustments to the positioning.

[0050] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0051] The present invention has been described in detail above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
