Description

Technical Field

[0001] The present invention relates to the technical field of industrial printing, and in particular to an automatic coding device and a processing method thereof. Background Art

[0002] In the field of electronic product testing technology, there is a type of product with a convex front and a flat back. The products are stored in a collection box in groups of two, with the backs of the products pressed together in a single row vertically. Stacking is not allowed, otherwise they will be damaged by gravity. It is necessary to ensure a reasonable stacking density in the collection box.

[0003] During the semi-automated manual inspection of the above-mentioned products, the operator needs to place the products one by one under the coding machine for coding. This process will face two problems: First, if the operator puts the coded products back into the original collection box, the operator may miss the uncoded products or code them twice. Second, if the operator places the coded products into another collection box, the operator needs to manually support the products to keep them in an upright position to ensure that the coded products remain in an upright position. As the coding process progresses, the operator needs to support the products in two collection boxes at the same time and perform the coding operation, which increases the risk of improper support causing the products in the collection boxes to collapse and collide, thereby causing product damage. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic coding device and a processing method thereof to solve the problem of product damage caused by manual semi-automatic coding in the prior art.

The second positioning mechanism has at least the degree of freedom in the first direction and the vertical direction. The two groups of the second positioning mechanism alternately restrict the products in the collection box of the unloading area.

[0007] Preferably, the first flipping assembly is divided into two groups, and the two groups of the first flipping assemblies are arranged on both sides of the first transfer assembly. The first flipping assembly also has an additional rotational freedom with an axis perpendicular to the second direction as the rotation center. The output end of the first flipping assembly includes a first adsorption module. The initial state of the two groups of the first adsorption modules is horizontally relative to each other, which is used to achieve product posture adjustment.

[0008] Preferably, the first positioning mechanism includes a first supporting member, which is slidably connected to the loading area of ​​the first conveyor belt along the first direction, and the first supporting member is provided with a first positioning cylinder and a second positioning cylinder on both sides along the first direction. The piston rod of the first positioning cylinder is fixed with a first limiting member, and the piston rod of the second positioning cylinder is fixed with a second limiting member. A vertical positioning gap is formed between the first limiting member and the second limiting member, and the first limiting member and the second limiting member both extend into the collection box in the loading area.

[0009] Preferably, the first transfer mechanism extends from the second conveyor belt to the first conveyor belt, and the first transfer mechanism is located on the first conveyor belt and a first detection module is fixedly provided at the end thereof, and the first detection module is electrically connected to the first transfer mechanism.

[0010] Preferably, the second transfer mechanism also includes a second transfer component, which is located in the middle of the two groups of second flipping components. The second transfer component has translational freedom in the first direction, the second direction and the vertical direction. The output end of the second transfer component includes a first clamp for clamping a group of products. The second transfer mechanism is provided with a second detection module facing the first conveyor belt.

[0011] Preferably, the second positioning mechanism is composed of at least two groups, and the two groups of positioning mechanisms are arranged on both sides of the first conveyor belt along the second direction. The second positioning mechanism has the freedom of translation in the first direction. The output end of the second positioning mechanism is provided with a third limit member and a fourth limit member that move along the vertical direction. A vertical positioning gap is formed between the third limit member and the fourth limit member, and the third limit member and the fourth limit member both extend into the collection box in the unloading area.

[0012] Preferably, both the loading area and the unloading area of ​​the first conveyor belt are provided with a limiting mechanism, and the limiting mechanism extends out of the first conveyor belt to block the collection box, or the limiting mechanism retracts into the first conveyor belt to allow the collection box to pass.

[0013] A processing method: S1. The limiting mechanism rises, limiting the collection box to remain stationary in the loading area. The first supporting member moves to the side of the collection box. The first positioning cylinder drives the first limiting member downward, inserting the first limiting member between the collection box and the first group of products at the edge. The second positioning cylinder drives the second limiting member downward, inserting the second limiting member into the gap between the first group of products and the adjacent group of products. S2. The first detection module detects the group of products restricted by the first positioning mechanism, and the first transfer assembly drives the first clamp to clamp the group of products and transfer the group of products to the top of the second conveyor belt while maintaining the group of products in a vertical state. S3. The two first adsorption modules each adsorb a product. The first clamp releases the product, causing the two first slide rails to move in opposite directions to separate the two products. The two sets of first flipping assemblies simultaneously flip the two products in the group, turning the two products from a vertical state to a horizontal state. The two first adsorption modules then place the two products on the second conveyor belt. S4. After the products between the first and second limiting members are removed, the second positioning cylinder drives the second limiting member to rise and exceed the height of the products. The first supporting member moves along the first direction by the thickness of a group of products. The first limiting member fits the group of products at the edge and restricts the remaining products. The second limiting member is inserted into the gap between the group of products at the edge and the adjacent group of products for identification and transfer by the first transfer mechanism. S5, repeating steps S3 and S4 in sequence until all products in the collection box are transferred to the second conveyor belt, the limiting mechanism releases the collection box, and the collection box is conveyed to the unloading area; S6. The second conveyor belt passes the products in the loading area through the coding area in sequence. The coding mechanism automatically codes the products in sequence and then conveys them to the unloading area. S7. The two second adsorption modules each adsorb a coded product. The second flipping assembly drives the two products off the second conveyor belt and turns the two products from a horizontal state to a vertical state. The two second flipping assemblies move toward each other so that the backs of the two products fit together to form a group of products. S8. The two second positioning members move to the edge of the collection box near the unloading area along the first direction, that is, the third limiter and the fourth limiter are located at the edge of the collection box. The second transfer assembly drives the second clamp to clamp the group of products. The second detection module identifies the third limiter and the fourth limiter. The second transfer assembly transfers the group of products from above the second conveyor belt to the gap between the third limiter and the fourth limiter. S9. The third limiter and the fourth limiter of the first group of second positioning mechanisms rise and separate from the group of products. The first group of second positioning mechanisms moves the thickness of a group of products along the first direction. The third limiter and the fourth limiter fall. The outer side wall of the fourth limiter serves to limit the group of products. During this process, the second group of second positioning mechanisms is in a stationary state. The second group of second positioning mechanisms drives the third limiter and the fourth limiter of the group to rise and separate from the group of products. The second supporting member of the second group of second positioning mechanisms moves the thickness of a group of products along the first direction. On the one hand, the second positioning mechanism limits the products already loaded in the collection box to maintain a vertical state. On the other hand, it positions the loading of the next group of products.

[0014] Compared with the prior art, the advantages of the present invention are: The first conveyor belt and the second conveyor belt are used to reasonably divide the loading, coding and unloading areas, and the coding mechanism, the first positioning mechanism and the second positioning mechanism are used to accurately position the products. The first transfer mechanism and the second transfer mechanism realize the automatic transfer and state conversion of the products from the collection box to the second conveyor belt after coding and then returned to the collection box. This effectively solves the problems of manual coding omissions, repeated coding, and manual support of products causing collapse and collision damage in electronic product testing, improves coding accuracy and efficiency, and reduces the risk of product damage.

[0017] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1 and Figure 2 As shown, an automatic coding device includes a first conveyor belt 1 for conveying a collection box 100 and a second conveyor belt 2 for conveying products 200. Both the first conveyor belt 1 and the second conveyor belt 2 are arranged along a first direction. A coding mechanism 8 is provided on the side of the second conveyor belt 2, with the coding end of the coding mechanism 8 facing the end surface of the second conveyor belt 2, and is used to code the products 200 located on the second conveyor belt 2. A first transfer mechanism 3 and a second transfer mechanism 5 are provided on the top of the second conveyor belt 2, and are located on either side of the coding mechanism 8. The first transfer mechanism 3 is used to transfer the products 200 from the vertical storage state in the collection box 100 to the second conveyor belt 2 in a flat state. The second transfer mechanism 5 is used to transfer the products 200 from the second conveyor belt 2 to the collection box 100, and the products 200 are placed vertically into the collection box 100. A first positioning mechanism 4 and a second positioning mechanism 6 are slidingly connected to the first conveyor belt 1. The first positioning mechanism 4 corresponds to the first transfer mechanism 3, and the second positioning mechanism 6 corresponds to the second transfer mechanism 5. They are used to support and limit the products 200 in the collection box 100 at relative positions to realize automatic loading and unloading and coding operations of the products 200, thereby avoiding damage to the products 200 during the coding process.

[0021] For the convenience of explanation, an automatic coding equipment is divided into a loading area 300, a coding area 400 and a unloading area 500 along the first direction. Specifically, the first transfer mechanism 3 and the first positioning mechanism 4 are located in the loading area 300, the coding mechanism 8 is located in the coding area 400, and the second transfer mechanism 5 and the second positioning mechanism 6 are located in the unloading area 500.

[0022] The first direction is defined as the lengthwise direction of the first conveyor belt 1, and this direction is horizontal. The second direction is a planar direction perpendicular to the first direction and coplanar with the first direction. The first and second directions together form an orthogonal coordinate system within the same horizontal plane, where the first direction corresponds to the longitudinal extension of the conveyor belt, and the second direction corresponds to the transverse extension of the conveyor belt. This definition clarifies the horizontal coplanarity of the two directions and their spatial orthogonal relationship, facilitating the accurate description of subsequent technical features.

[0023] The first conveyor belt 1 includes a first fixed portion 11 and a first conveying portion 12. The first conveying portion 12 is rotatably connected to the first fixed portion 11. In this embodiment, the first fixed portion 11 is a hollow frame, and the first conveying portion 12 comprises a plurality of rollers evenly distributed along a first direction. The tops of the plurality of rollers are all located at the same horizontal plane, which is lower than the top end surface of the first fixed portion 11. A collection box 100 is placed on the first conveying portion 12. The two side surfaces of the collection box 100 along the second direction are constrained by the first fixed portion 11, so that the collection box 100 can only move along the first direction with the first conveying portion 12.

[0024] Because the collection box 100 needs to remain stationary while waiting for the first transfer mechanism 3 to transfer the products 200, it is preferably controlled by a motor to stop the rollers so that the collection box 100 stops within the operating range of the first transfer mechanism 3. More preferably, the first fixed portion 11 is provided with a limiting mechanism 71. The limiting mechanism 71 is located at the junction of the loading area 300 and the inspection area. The limiting mechanism 71 includes a limiting cylinder 711 and a stopper 712. The cylinder body of the limiting cylinder 711 is fixed to the first fixed portion 11, and the stopper 712 is fixed to the piston rod of the limiting cylinder 711. When the piston rod is retracted in the limiting cylinder 711, the stopper 712 is lower than the first conveying portion 12, and the collection box 100 moves with the first conveying portion 12 from the loading area 300 to the unloading area 500. When the piston rod extends upward from the limiting cylinder 711, the piston rod drives the limiting member above the first conveying portion 12, thereby limiting the movement of the collection box 100. In this embodiment, both the loading area 300 and the unloading area 500 of the first conveyor belt 1 are provided with a limiting mechanism 71 .

[0025] The second conveyor belt 2 includes a second fixed portion 21 and a second conveying portion 22. In this embodiment, the second fixed portion 21 is a frame extending along the first direction, and the second conveying portion 22 is a belt. That is, the product 200 passes through the loading area 300, the coding area 400 and the unloading area 500 in sequence through the belt drive, ensuring that the product 200 and the second conveying portion 22 can move synchronously.

[0026] like Figure 3 and Figure 4As shown, the first positioning mechanism 4 includes a first positioning guide rail 41, a first supporting member 42, a first positioning cylinder 43 and a second positioning cylinder 44. The first positioning guide rail 41 is fixed to the first fixed part 11 along the first direction, and the first supporting member 42 is slidably connected to the first positioning guide rail 41 along the first direction. The first supporting member 42 extends upward, and the first positioning cylinder 43 and the second positioning cylinder 44 are respectively fixed on both sides of the first supporting member 42 along the first direction. The first positioning cylinder 43 and the second positioning cylinder 44 are both arranged in the vertical direction, and the piston rod of the first positioning cylinder 43 is fixed with a first limiting member 45, and the second positioning cylinder 44 is fixed with a second limiting member 46. The first limiting member 45 and the second limiting member 46 are both approximately "L-shaped", that is, the first limiting member 45 and the second limiting member 46 extend along the second direction to the top of the first conveying part 12, and then extend downward. A vertical positioning gap is formed between the first limiting member 45 and the second limiting member 46, which is used to limit a group of products 200. That is, the first limiting member 45 can be inserted into the gap between the two groups of products 200, and the second limiting member 46 can be inserted into the gap of another adjacent product 200, and the first limiting member 45 and the second limiting member 46 move independently of each other.

[0027] Preferably, a group of first positioning mechanisms 4 are fixed to the first fixing parts 11 on both sides of the first conveying part 12 in the loading area 300 along the second direction, and the two groups of positioning mechanisms respectively limit the two corresponding edges of the product 200 to prevent the product 200 from deflecting.

[0028] The first transfer mechanism 3 includes a first transfer assembly 31 and a first flip assembly 32. The first transfer assembly 31 has translational freedom along the first direction, the second direction, and the vertical direction. Specifically, the first transfer assembly 31 includes a first guide rail 311, a second guide rail 312, and a first drive cylinder 313. The first guide rail 311 is fixed to the frame, extending along the first direction and covering the loading area 300. The second guide rail 312 is slidably connected to the first guide rail 311 along the first direction, and the second guide rail 312 extends along the second direction from the second conveyor belt 2 to above the first conveyor belt 1. The first drive cylinder 313 is vertically downwardly arranged and slidably connected to the second guide rail 312 along the second direction. The piston rod of the first drive cylinder 313 is fixed with a first clamp 314 for clamping the product 200. In this embodiment, the first clamp 314 moves to the top of the opening of the collection box 100 through the first guide rail 311 and the second guide rail 312. The first clamp 314 clamps a group of products 200 supported by the first limit member 45 and the second limit member 46, and transfers the group of products 200 to the top of the second conveyor belt 2.

[0029] A first detection module 315 is fixedly provided at one end of the second guide rail 312 close to the first conveyor belt 1 . The first detection module 315 is electrically connected to the first transfer mechanism 3 for identifying the product 200 in the collection box 100 and transmitting information signals to the first transfer mechanism 3 .

[0030] A first support rail 33 is fixedly mounted on the frame of the second conveyor belt 2, facing away from the first conveyor belt 1. The first support rail 33 extends in a first direction.

The output shaft of the first motor 322 is horizontally arranged in the second direction and fixedly connected to the second motor 323 via a bracket. The output shaft of the second motor 323 is perpendicular to the output shaft of the first motor 322. A first suction module 324 is fixedly mounted on the output shaft of the second motor 323 for sucking the product 200 and adjusting its posture. In this embodiment, the first suction module 324 is an electrostatic chuck. In the initial state, the first suction module 324 is horizontally positioned, facing the front of the product 200.

[0031] Two sets of first flipping assemblies 32 are located on either side of the first clamp 314. They absorb the two products 200 held by the first clamp 314. The two first slide rails 321 slide in opposite directions to prevent interference between the products 200 when adjusting their positions. The two first motors 322 each rotate 90 degrees, turning the vertical products 200 into a horizontal position. The two second motors 323 rotate 90 degrees in opposite directions, ensuring that each product 200 faces up and in the same orientation, facilitating subsequent uniform coding of the products 200.

[0032] A loading mechanism 91 is provided on the side of the first conveyor belt 1 in the loading area 300 facing away from the second conveyor belt 2. The loading mechanism 91 includes a loading guide rail 911, a loading robot arm 912 and a loading clamp 913. In this embodiment, the loading clamp 913 is a translational clamp to simultaneously clamp two mutually fitting collection boxes 100 and transfer them to the first conveyor belt 1.

[0033] like Figure 5As shown, the coding mechanism 8 includes an adjustment rail 81, an adjustment cylinder 82, and a coding module 83. The adjustment rail 81 is fixed to the frame of the coding area 400 and extends in the vertical direction. The adjustment cylinder 82 is slidably connected to the adjustment rail 81 in the vertical direction. The piston rod of the adjustment cylinder 82 extends and retracts in the second direction toward the top of the second conveyor belt 2. The coding module 83 is fixed to the end face of the piston rod. After detecting the product 200, the coding module 83 automatically codes the passing product 200.

[0034] like Figure 6 As shown, the second positioning mechanism 6 is arranged on the first conveyor belt 1 in the unloading area 500. The second positioning mechanism 6 includes a second positioning guide rail 61, a second supporting member 62, a third positioning cylinder 63 and a fourth positioning cylinder 64. The second positioning guide rail 61 is fixed to the first fixed part 11 along the first direction, and the second supporting member 62 is slidably connected to the second positioning guide rail 61 along the first direction. The movement range of the second supporting member 62 is the unloading area 500. The second supporting member 62 extends upward, and the third positioning cylinder 63 and the fourth positioning cylinder 64 are respectively fixed on both sides of the second supporting member 62 along the first direction. The third positioning cylinder 63 and the fourth positioning cylinder 64 are both arranged vertically upward. The piston rod of the third positioning cylinder 63 is fixed with a third limiting member 65, and the piston rod of the fourth positioning cylinder 64 is fixed with a fourth limiting member 66. The third limiting member 65 and the fourth limiting member 66 extend along the second direction to the top of the first conveying part 12, and then extend downward. A vertical positioning gap is formed between the third limiting member 65 and the fourth limiting member 66 for limiting a group of products 200 .

[0035] Preferably, a group of second positioning mechanisms 6 are respectively fixed to the first fixed part 11 on both sides of the first conveying part 12 located in the unloading area 500 along the second direction. The two groups of positioning mechanisms respectively limit the two corresponding edges of the product 200 to prevent the risk of deviation or collision of the product 200.

[0036] The second transfer mechanism 5 includes a second transfer assembly 51 and a second flip assembly 52. ​​The second transfer assembly 51 has translational freedom along the first direction, the second direction, and the vertical direction. Specifically, the second transfer assembly 51 includes a third guide rail 511, a fourth guide rail 512, and a second drive cylinder 513. The third guide rail 511 is fixed to the frame and extends along the first direction. The fourth guide rail 512 is slidably connected to the third guide rail 511 along the second direction. The fourth guide rail 512 extends along the second direction from the second conveyor belt 2 to above the first conveyor belt 1. The second drive cylinder 513 is vertically downwardly arranged and slidably connected to the fourth guide rail 512 along the second direction. The piston rod of the second drive cylinder 513 is fixed with a second clamp 514 for clamping the product 200. The second clamp 514 moves to above the second conveyor belt 2 through the third guide rail 511 and the fourth guide rail 512, clamps the group of products 200 to be bonded, and transfers the group of products 200 to the gap limited by the third limit member 65 and the fourth limit member 66.

[0037] A second detection module 515 is fixedly provided at one end of the fourth guide rail 512 close to the first conveyor belt 1 . The second detection module 515 is electrically connected to the second transfer mechanism 5 for identifying the gap between the third limit member 65 and the fourth limit member 66 .

[0038] A second support rail 53 is provided on the frame of the second conveyor belt 2, facing away from the first conveyor belt 1. The second support rail 53 extends in a first direction.

There is a gap between the product 200 in the collection box 100 and the inner wall of the collection box 100 along the second direction, which may cause misalignment between adjacent products 200. The first clamp 314 or the second clamp 514 may clamp the electronic components on the product 200, and there is a risk of damaging the product 200. The shifting mechanism 72 is used to press the product 200 against the collection box 100 along the second direction. The shifting mechanism 72 includes a shifting cylinder 721 and a shifting plate 722. The shifting cylinder 721 is connected to the first fixed part 11 by sliding along the second direction through a slide rail. One end of the shifting plate 722 is fixed to the piston rod of the shifting cylinder 721, and the other end extends along the first direction. The length of the shifting plate 722 is smaller than the size of the collection box 100 along the first direction, so that the shifting plate 722 can extend into the collection box 100. The shifting cylinder 721 slides relative to the cylinder to push the product 200 against the inner wall of the collection box 100.

[0042] A processing method: S1. The loading mechanism 91 clamps the collection box 100 loaded with the products 200 to be coded and transfers it to the first conveying section 12 of the first conveyor belt 1. The limit cylinder 711 drives the stopper 712 to rise, so that the collection box 100 is stationary in the loading area 300. S2. The first carrier 42 moves along the first direction to the edge of the collection box 100 via the first guide rail 311. The first positioning cylinder 43 drives the first limiting member 45 to descend, so that the first limiting member 45 extends into the collection box 100. The first limiting member 45 is inserted into the gap between the inner wall of the collection box 100 and the group of products 200. The second positioning cylinder 44 drives the second limiting member 46 to descend, so that the second limiting member 46 also extends into the collection box 100. The second limiting member 46 is inserted into the gap between the group of products 200 and the adjacent group of products 200. That is, the first limiting member 45 and the second limiting member 46 limit the group of products 200 at the outermost edge of the collection box 100. S3: The first detection module 315 detects the group of products 200 restrained by the first positioning mechanism 4. The first guide rail 311, the second guide rail 312, and the first driving cylinder 313 cooperate to drive the first clamp 314 to clamp the group of products 200 and transfer the group of products 200 to the top of the second conveyor belt 2 in a vertical state. S4. The two groups of first flipping assemblies 32 flip the two products 200 in the group simultaneously. In the initial state, the first adsorption module 324 is horizontally facing the front of the product 200. The two first slide rails 321 move toward each other relative to the first support rail 33, so that the two first adsorption modules 324 each adsorb a piece of product 200. The two first slide rails 321 move in opposite directions to separate the two products 200. The two first motors 322 rotate 90 degrees in opposite directions. The first adsorption modules 324 are vertically downward, so that the two products 200 are transformed from a vertical state to a horizontal state. The two second motors 323 rotate 90 degrees in opposite directions so that the two products 200 have the same orientation. The two first motors 322 move downward relative to the first slide rails 321. The two first adsorption modules 324 place the corresponding two products 200 on the second conveyor belt 2. S5. After the products 200 between the first limiting member 45 and the second limiting member 46 are removed, the second positioning cylinder 44 drives the second limiting member 46 to rise and exceed the height of the products 200. The first supporting member 42 moves along the first direction by the thickness of a group of products 200. The first limiting member 45 fits the group of products 200 at the edge and restricts the remaining products 200. The second limiting member 46 is inserted into the gap between the group of products 200 at the edge and the adjacent group of products 200, so as to be recognized and transferred by the first transfer mechanism 3. S6, repeating steps S4 and S5 until all the products 200 in the collection box 100 are transferred to the second conveyor belt 2, the limit cylinder 711 drives the stopper to descend, releasing the collection box 100, and the collection box 100 is transported to the unloading area 500 by the first conveyor belt 1; S7, the second conveyor belt 2 passes the products 200 located in the loading area 300 through the coding area 400 in sequence, and the coding mechanism 8 automatically codes the products 200 in sequence, and then conveys them to the unloading area 500; S8. The two second flipping assemblies 52 are in the same initial state, that is, the two second adsorption modules 524 are vertically downward facing the second conveyor belt 2, the third motor 522 is downward relative to the second slide rail 521, and the two second adsorption modules 524 each adsorb a coded product 200. The two third motors 522 rise, so that the two products 200 are separated from the second conveyor belt 2. The two third motors 522 rotate 90 degrees in opposite directions, so that the two products 200 are transformed from a horizontal state to a vertical state. The two fourth motors 523 rotate 90 degrees in opposite directions, so that the two products 200 are mirror-symmetrical in the vertical plane. The two second slide rails 521 move relative to each other, so that the backs of the two products 200 are attached to form a group of products 200. S9. The two second carriers 62 move to the edge of the collection box 100 along the first direction near the unloading area 500, that is, the edge where the third limiter 65 and the fourth limiter 66 are located inside the collection box 100. The third guide rail 511, the fourth guide rail 512, and the second driving cylinder 513 cooperate to drive the second clamp 514 to clamp the group of products 200. The second detection module 515 identifies the third limiter 65 and the fourth limiter 66. The second transfer assembly 51 transfers the group of products 200 to the gap between the third limiter 65 and the fourth limiter 66. S10, wherein the third positioning cylinder 63 and the fourth positioning cylinder 64 of the first group of second positioning mechanisms 6 drive the third limiting member 65 and the fourth limiting member 66 to rise and separate from the group of products 200, the second supporting member 62 of the first group of second positioning mechanisms 6 moves the thickness of a group of products 200 along the first direction, the third limiting member 65 and the fourth limiting member 66 descend, and the outer side wall of the fourth limiting member 66 plays a role in limiting the group of products 200. During this process, the second group of second positioning mechanisms 6 is in a stationary state, the third positioning cylinder 63 and the fourth positioning cylinder 64 of the second group of second positioning mechanisms 6 drive the third limiting member 65 and the fourth limiting member 66 to rise and separate from the group of products 200, the second supporting member 62 of the second group of second positioning mechanisms 6 moves the thickness of a group of products 200 along the first direction, on the one hand limiting the products 200 already loaded in the collection box 100 to maintain a vertical state, on the other hand positioning the loading of the next group of products 200.
