Description

Technical Field

[0001] This invention relates to the field of industrial printing technology, and in particular to an automatic coding device and its processing method. Background Technology

[0002] In the field of electronic product testing technology, there is a type of product with a raised front and a flat back. These products are stored in a collection box in pairs, with their backs touching, in a single row. Stacking is not allowed, otherwise they will be damaged due to pressure from gravity. A reasonable stacking density must be ensured within the collection box.

[0003] During the semi-automated manual inspection of the above products, operators need to place each product under the coding machine for coding. This process presents two problems: First, if the operator puts the coded product back into the original collection box, the operator may miss uncoded products or perform duplicate coding. Second, if the operator places the coded product into another collection box, the operator needs to manually support the product to keep it upright to ensure that the coded product remains upright. As the coding process progresses, the operator needs to support products in two collection boxes simultaneously while performing the coding operation, increasing the risk that improper support may cause the products in the collection box to collapse and collide, thereby causing product damage. Summary of the Invention

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

[0005] The technical solution of the present invention is: an automatic coding device and its processing method, comprising: a first conveyor belt for conveying a collection box, which is divided into a feeding area, a coding area and a discharging area along a first direction;

[0006] The second conveyor belt, parallel to the first conveyor belt, is used to sequentially transport products through the loading area, coding area and unloading area;

[0007] A coding mechanism is located in the coding area, with its coding end facing the second conveyor belt, and is used to code products located on the second conveyor belt.

[0008] The first positioning mechanism has at least translational degrees of freedom in the first direction and the vertical direction, and its output end is used to restrict the products in the collection box of the feeding area;

[0009] The first transfer mechanism has at least translational degrees of freedom along the second direction and the vertical direction, and rotational degrees of freedom about the second direction as an axis, for transferring products from the vertical storage state of the collection box to the second conveyor belt and laying them flat. The first positioning mechanism and the first transfer mechanism are both located in the loading area.

[0010] The second transfer mechanism has at least translational degrees of freedom in the second direction and the vertical direction, and rotational degrees of freedom about the second direction as an axis, for transferring the product vertically from the second conveyor belt to the collection box;

[0011] The second positioning mechanism has at least two sets disposed on both sides of the first conveyor belt. The second positioning mechanism has at least a first direction and a vertical direction of freedom. The two sets of the second positioning mechanism alternately restrict the products in the collection box of the feeding area.

[0012] Preferably, the first transfer mechanism includes a first transfer component and a first flipping component. The first transfer component has translational degrees of freedom in a first direction, a second direction, and a vertical direction. The output end of the first transfer component includes a first clamp for holding a group of products. The first flipping component has at least a translational degree of freedom in the first direction and a rotational degree of freedom about the second direction as an axis. The output end of the first flipping component includes a first adsorption module for adsorbing a product.

[0013] Preferably, there are two sets of the first flipping components, which are respectively disposed on both sides of the first transfer component. The first flipping component also has an additional rotational degree of freedom with an axis perpendicular to the second direction as the rotation center. The initial state of the two sets of the first adsorption modules is horizontally opposite to each other, which is used to realize the posture adjustment of the product.

[0014] Preferably, the first positioning mechanism includes a first carrier member, which is slidably connected to the feeding area of ​​the first conveyor belt along a first direction. A first positioning cylinder and a second positioning cylinder are respectively provided on both sides of the first carrier member along the first direction. A first limiting member is fixedly provided on the piston rod of the first positioning cylinder, and a second limiting member is fixedly provided on the piston rod of the second positioning cylinder. A vertical positioning gap is formed between the first limiting member and the second limiting member. Both the first limiting member and the second limiting member extend into the collection box of the feeding area.

[0015] Preferably, the first transfer mechanism extends from the second conveyor belt to the first conveyor belt, and a first detection module is fixedly installed at the end of the first transfer mechanism on the first conveyor belt. The first detection module is electrically connected to the first transfer mechanism.

[0016] Preferably, the second transfer mechanism further includes a second transfer component located between two sets of second flipping components. The second transfer component has translational degrees of freedom in a first direction, a second direction, and a vertical direction. The output end of the second transfer component includes a first clamp for holding a set of products. The second transfer mechanism is provided with a second detection module facing the first conveyor belt.

[0017] Preferably, the second positioning mechanism comprises at least two sets, which are respectively disposed on both sides of the first conveyor belt along the second direction. The second positioning mechanism has a first direction translational degree of freedom. The output end of the second positioning mechanism is provided with a third limiting member and a fourth limiting member that move in the vertical direction. A vertical positioning gap is formed between the third limiting member and the fourth limiting member. Both the third limiting member and the fourth limiting member extend into the collection box of the unloading area.

[0018] Preferably, both the loading and unloading areas of the first conveyor belt are equipped with limiting mechanisms. The limiting mechanisms extend out of the first conveyor belt to block the collection box, or the limiting mechanisms retract into the first conveyor belt to allow the collection box to pass through.

[0019] One processing method:

[0020] S1. The limiting mechanism rises, restricting the collection box to remain stationary in the feeding area. The first carrier moves to the side of the collection box. The first positioning cylinder drives the first limiting member to descend. The first limiting member is inserted between the collection box and the first group of products located at the edge. The second positioning cylinder drives the second limiting member to descend. The second limiting member is inserted into the gap between the group of products and the adjacent group of products.

[0021] S2. The first detection module detects the group of products restricted by the first positioning mechanism, and the first transfer component drives the first clamp to hold the group of products and transfer the group of products in a vertical state to the top of the second conveyor belt.

[0022] S3. The two first adsorption modules adsorb one product respectively. The first clamp releases the product. The two sets of first flipping components move in opposite directions to separate the two products. The two sets of first flipping components flip the two products in the same set at the same time. The two products change from a vertical state to a horizontal state. The two first adsorption modules place the two products on the second conveyor belt.

[0023] S4. After the product between the first limiting member and the second limiting member is removed, the second positioning cylinder drives the second limiting member to rise and exceed the height of the product. The first bearing member moves a distance equal to the thickness of a set of products along the first direction. The first limiting member fits against a set of products located at the edge and restricts the remaining products. The second limiting member is inserted into the gap between a set of products located at the edge and a set of products adjacent to it, so that the first transfer mechanism can identify and transfer them.

[0024] S5. Repeat steps S3 and S4 until all the products in the collection box are transferred to the second conveyor belt. The limiting mechanism releases the collection box, and the collection box is transported to the unloading area.

[0025] S6. The second conveyor belt will sequentially pass the products located in the loading area through the coding area. The coding mechanism will automatically code the products sequentially and then transport them to the unloading area.

[0026] S7. The two second adsorption modules each adsorb a product that has been coded. The second flipping component drives the two products to leave the second conveyor belt and changes the two products from a horizontal state to a vertical state. The two second flipping components move towards each other, so that the backs of the two products are put together to form a set of products.

[0027] S8. The two sets of second positioning mechanisms move to the edge of the collection box near the unloading area along the first direction, that is, the third and fourth limiting members are located at the edge inside the collection box. The second transfer component drives the second clamp to hold the group of products. The second detection module identifies the third and fourth limiting members. The second transfer component transfers the group of products from above the second conveyor belt to the gap between the third and fourth limiting members.

[0028] S9. The third and fourth limiting members of the first group of second positioning mechanisms rise and detach from the group of products. The first group of second positioning mechanisms moves the thickness of the group of products along the first direction. The third and fourth limiting members descend. The outer wall of the fourth limiting member restricts the group of products. During this process, the second group of second positioning mechanisms is stationary. The second group of second positioning mechanisms drives the third and fourth limiting members of the group to rise and detach from the group of products. The second bearing member of the second group of second positioning mechanisms moves the thickness of the group of products along the first direction. The second positioning mechanism restricts the products already loaded in the collection box to maintain a vertical state on the one hand, and positions the loading of the next group of products on the other hand.

[0029] Compared with the prior art, the advantages of the present invention are:

[0030] By rationally dividing the feeding, coding, and unloading areas using the first and second conveyor belts, and coordinating with the coding mechanism, the first positioning mechanism, and the second positioning mechanism to accurately position the products, as well as the first and second transfer mechanisms, the automatic transfer and state transition of products from the collection box to the second conveyor belt for coding and then back to the collection box is achieved. This effectively solves the problems of easy omissions and repeated coding during manual coding in electronic product testing, as well as the collapse and collision damage caused by manual support of products. It improves coding accuracy and efficiency and reduces the risk of product damage. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0043] 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 face of the second conveyor belt 2, for coding 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, respectively located on both sides of the coding mechanism 8. The first transfer mechanism 3 is used to transfer the products 200 from the vertical storage state of 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 into the collection box 100, with the products 200 placed vertically into the collection box 100. The first conveyor belt 1 is slidably connected to a first positioning mechanism 4 and a second positioning mechanism 6. 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 product 200 in the collection box 100 at the relative position, so as to realize the automated loading, unloading and coding operation of the product 200 and avoid damage to the product 200 during the coding process.

[0044] For ease of explanation, an automatic coding device is divided into a feeding area 300, a coding area 400, and a discharging area 500 along a first direction. Specifically, the first transfer mechanism 3 and the first positioning mechanism 4 are located in the feeding 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 discharging area 500.

[0045] The first direction is defined as the length 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 direction and the second direction together form an orthogonal coordinate system in the same horizontal plane, where the first direction corresponds to the longitudinal extension direction of the conveyor belt, and the second direction corresponds to the transverse extension direction of the conveyor belt. This definition clarifies the horizontal coplanarity of the two directions and their spatial orthogonality, facilitating the accurate description of subsequent technical features.

[0046] The first conveyor belt 1 includes a first fixing part 11 and a first conveying part 12. The first conveying part 12 is rotatably connected to the first fixing part 11. In this embodiment, the first fixing part 11 is a hollow frame, and the first conveying part 12 consists of a plurality of rollers evenly distributed along a first direction. The tops of the rollers are all located on the same horizontal plane, which is lower than the top end face of the first fixing part 11. A collection box 100 is placed on the first conveying part 12. The two sides of the collection box 100 along the second direction are restricted by the first fixing part 11, so that the collection box 100 can only move along the first direction with the first conveying part 12.

[0047] Since the collection box 100 needs to remain stationary and wait for the first transfer mechanism 3 to transfer the product 200, preferably, the rollers are stopped by a motor to stop the collection box 100 within the operating range of the first transfer mechanism 3. More preferably, the first fixing part 11 is provided with a limiting mechanism 71, which is located at the junction of the loading area 300 and the detection area. The limiting mechanism 71 includes a limiting cylinder 711 and a stop member 712. The cylinder body of the limiting cylinder 711 is fixed to the first fixing part 11, and the stop member 712 is fixed to the piston rod of the limiting cylinder 711. When the piston rod retracts into the limiting cylinder 711, the stop member 712 is lower than the first conveying part 12, and the collection box 100 moves from the loading area 300 to the unloading area 500 with the first conveying part 12. When the piston rod extends upward out of the limiting cylinder 711, the piston rod drives the limiting member to be higher than the first conveying part 12, thereby restricting 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 equipped with limiting mechanisms 71.

[0048] The second conveyor belt 2 includes a second fixing part 21 and a second conveying part 22. In this embodiment, the second fixing part 21 is a frame extending along the first direction, and the second conveying part 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 by belt drive, ensuring that the product 200 and the second conveying part 22 can move synchronously.

[0049] like Figure 3 and Figure 4 As shown, the first positioning mechanism 4 includes a first positioning guide rail 41, a first support 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 a first direction, and the first support member 42 is slidably connected to the first positioning guide rail 41 along the first direction. The first support 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 support member 42 along the first direction. Both the first positioning cylinder 43 and the second positioning cylinder 44 are arranged vertically. 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. Both the first limiting member 45 and the second limiting member 46 are approximately "L-shaped", that is, the first limiting member 45 and the second limiting member 46 extend along the second direction to above 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 to restrict a group of products 200. That is, the first limiting member 45 can be inserted into the gap between two groups of products 200, and the second limiting member 46 can be inserted into the gap between another adjacent product 200. The first limiting member 45 and the second limiting member 46 move independently of each other.

[0050] Preferably, a set of first positioning mechanisms 4 are fixedly provided on the first fixed parts 11 on both sides of the first conveying part 12 in the feeding area 300 along the second direction. The two sets of positioning mechanisms respectively restrict the two corresponding edges of the product 200 to prevent the product 200 from shifting.

[0051] The first transfer mechanism 3 includes a first transfer component 31 and a first tilting component 32. The first transfer component 31 has translational degrees of freedom along a first direction, a second direction, and a vertical direction. Specifically, the first transfer component 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 on the frame, extends along the first direction, and covers the loading area 300. The second guide rail 312 is slidably connected to the first guide rail 311 along the first direction and 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 downward 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 above the opening of the collection box 100 via 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 limiting member 45 and the second limiting member 46, and transfers the group of products 200 to above the second conveyor belt 2.

[0052] The second guide rail 312 is fixedly provided with a first detection module 315 at one end near the first conveyor belt 1. The first detection module 315 is electrically connected to the first transfer mechanism 3 and is used to identify the product 200 in the collection box 100 and transmit the information signal to the first transfer mechanism 3.

[0053] A first support rail 33 is fixedly mounted on the frame of the second conveyor belt 2 away from the first conveyor belt 1. The first support rail 33 extends along a first direction. The first flipping assembly 32 includes a first slide rail 321 and a first motor 322. The first slide rail 321 is slidably connected to the first support rail 33 along the first direction and extends vertically. The first motor 322 is slidably connected to the side of the first slide rail 321 facing the second conveyor belt 2 along the vertical direction. The output shaft of the first motor 322 is horizontally set along a second direction. The output shaft of the first motor 322 is fixedly connected to a second motor 323 through a bracket. The output shaft of the second motor 323 is perpendicular to the output shaft of the first motor 322. A first adsorption module 324 is fixedly mounted on the output shaft of the second motor 323 for adsorbing the product 200 and adjusting the posture of the product 200. In this embodiment, the first adsorption module 324 is an electrostatic chuck. In the initial state, the first adsorption module 324 is horizontally facing the front of the product 200, that is, the first adsorption module 324 is horizontally set.

[0054] Two sets of first flipping components 32 are respectively disposed on both sides of the first clamp 314, respectively adsorbing the two products 200 held by the first clamp 314. The two first slide rails 321 slide in opposite directions to avoid interference between the products 200 when adjusting their posture. The two first motors 322 rotate 90 degrees respectively to change the vertical position of the products 200 to a horizontal position. The two second motors 323 rotate 90 degrees in opposite directions respectively, so that each product 200 faces upward and in the same direction, which facilitates the subsequent uniform coding operation of the products 200.

[0055] The first conveyor belt 1 of the loading area 300 is provided with a loading mechanism 91 on the side opposite to the second conveyor belt 2. The loading mechanism 91 includes a loading guide rail 911, a loading robotic arm 912 and a loading clamp 913. In this embodiment, the loading clamp 913 is a translational gripper, which can simultaneously clamp two mutually attached collection boxes 100 and transfer them to the first conveyor belt 1.

[0056] like Figure 5 As shown, the coding mechanism 8 includes an adjusting guide rail 81, an adjusting cylinder 82, and a coding module 83. The adjusting guide rail 81 is fixed on the frame of the coding area 400 and extends vertically. The adjusting cylinder 82 is slidably connected to the adjusting guide rail 81 in the vertical direction. The piston rod of the adjusting cylinder 82 extends and retracts towards the top of the second conveyor belt 2 in a second direction. 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.

[0057] like Figure 6 As shown, the second positioning mechanism 6 is located in the unloading area 500 of the first conveyor belt 1. The second positioning mechanism 6 includes a second positioning guide rail 61, a second carrier 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. The second carrier member 62 is slidably connected to the second positioning guide rail 61 along the first direction, and the movement range of the second carrier member 62 is the unloading area 500. The second carrier 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 carrier member 62 along the first direction. Both the third positioning cylinder 63 and the fourth positioning cylinder 64 are 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 to limit a group of products 200.

[0058] Preferably, a set of second positioning mechanisms 6 are fixedly provided on the first fixing parts 11 on both sides of the first conveying part 12 in the unloading area 500 along the second direction. The two sets of positioning mechanisms respectively restrict the two corresponding edges of the product 200 to prevent the product 200 from shifting or colliding.

[0059] The second transfer mechanism 5 includes a second transfer component 51 and a second flipping component 52. The second transfer component 51 has translational degrees of freedom along a first direction, a second direction, and a vertical direction. Specifically, the second transfer component 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 and 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 downward 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 above the second conveyor belt 2 via the third guide rail 511 and the fourth guide rail 512, clamps a group of products 200 that are being bonded, and transfers the group of products 200 into the gap restricted by the third limit member 65 and the fourth limit member 66.

[0060] A second detection module 515 is fixedly installed at one end of the fourth guide rail 512 near the first conveyor belt 1. The second detection module 515 is electrically connected to the second transfer mechanism 5 and is used to identify the gap between the third limiting member 65 and the fourth limiting member 66.

[0061] The second conveyor belt 2 has a second support rail 53 on its frame opposite to the first conveyor belt 1. The second support rail 53 extends along a first direction. The second flipping assembly 52 includes a second slide rail 521 and a third motor 522. The second slide rail 521 is slidably connected to the first support rail 33 along the first direction and extends vertically. The third motor 522 is slidably connected to the side of the second slide rail 521 facing the second conveyor belt 2 along the vertical direction. The output shaft of the third motor 522 is horizontally arranged along a second direction. A fourth motor 523 is fixed to the output shaft of the third motor 522 via a bracket. The output shaft of the fourth motor 523 is perpendicular to the output shaft of the first motor 322. A second adsorption module 524 is fixed to the output shaft of the fourth motor 523 for adsorbing the product 200 from the second conveyor belt 2 and transferring it after adjustment. In this embodiment, the second adsorption module 524 is an electrostatic chuck.

[0062] The second flipping component 52 consists of two sets, which are respectively located on both sides of the second clamp 514. Each set of flipping components adsorbs one product 200 and attaches the backs of the two products 200 together to form a set of products 200 for the second clamp 514 to hold.

[0063] The first conveyor belt 1 of the unloading area 500 is provided with an unloading mechanism 92 on the side opposite to the second conveyor belt 2. The unloading mechanism 92 includes an unloading guide rail 921, an unloading robotic arm 922 and an unloading clamp 923. In this embodiment, the unloading clamp 923 is a translational gripper to simultaneously clamp two mutually attached collection boxes 100 and transfer them to the first conveyor belt 1.

[0064] The first positioning mechanism 4 and / or the second positioning mechanism 6 are provided with a stop mechanism 72. If 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, it will cause misalignment between adjacent products 200. The first clamp 314 or the second clamp 514 will clamp the electronic components on the product 200, which may damage the product 200. The stop mechanism 72 is used to press the product 200 against the collection box 100 along the second direction. The gear shifting mechanism 72 includes a gear shifting cylinder 721 and a gear shifting plate 722. The gear shifting cylinder 721 is slidably connected to the first fixed part 11 along the second direction via a slide rail. One end of the gear shifting plate 722 is fixed to the piston rod of the gear shifting cylinder 721, and the other end extends along the first direction. The length of the gear shifting plate 722 is less than the size of the collection box 100 along the first direction, so that the gear shifting plate 722 can extend into the collection box 100. The gear shifting cylinder 721 slides relative to the cylinder to push the product 200 against the inner wall of the collection box 100.

[0065] One processing method:

[0066] S1. The feeding mechanism 91 clamps the collection box 100 loaded with the product to be coded 200 and transfers it to the first conveying section 12 of the first conveyor belt 1. The limit cylinder 711 drives the stop 712 to rise, so that the collection box 100 is stationary in the feeding area 300.

[0067] S2. The first carrier 42 moves along the first direction via the first guide rail 311 to the edge of the collection box 100. 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 a 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 restrict the group of products 200 located at the outermost edge of the collection box 100.

[0068] S3. The first detection module 315 detects the group of products 200 that are restricted by the first positioning mechanism 4. The first guide rail 311, the second guide rail 312 and the first drive 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 while keeping it in a vertical position.

[0069] S4. The two sets of first flipping components 32 simultaneously flip the two products 200 of the group. 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 towards each other relative to the first support rail 33, so that the two first adsorption modules 324 adsorb one piece of product 200 respectively. 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 module 324 is vertically downward, so that the two products 200 change 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 face the same direction. The two first motors 322 move downward relative to the first slide rail 321. The two first adsorption modules 324 place the corresponding two products 200 on the second conveyor belt 2.

[0070] S5. After the product 200 between the first limiting member 45 and the second limiting member 46 is removed, the second positioning cylinder 44 drives the second limiting member 46 to rise and exceed the height of the product 200. The first bearing member 42 moves a distance equal to the thickness of a set of products 200 along the first direction. The first limiting member 45 fits against a set of products 200 located at the edge and restricts the remaining products 200. The second limiting member 46 is inserted into the gap between a set of products 200 located at the edge and its adjacent set of products 200, so that the first transfer mechanism 3 can identify and transfer them.

[0071] S6. Repeat steps S4 and S5 until all products 200 in the collection box 100 are transferred to the second conveyor belt 2. The limit cylinder 711 will be driven to stop and lower, releasing the collection box 100. The collection box 100 is then transported by the first conveyor belt 1 to the unloading area 500.

[0072] S7. The second conveyor belt 2 will sequentially pass the product 200 located in the loading area 300 through the coding area 400. The coding mechanism 8 will automatically code the product 200 sequentially and then convey it to the unloading area 500.

[0073] S8. The two second flipping components 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, the two second adsorption modules 524 adsorb one product 200 that has been coded, 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 change 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 a 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 set of products 200;

[0074] S9. The two second carriers 62 move to the edge of the collection box 100 in the first direction near the unloading area 500, that is, the edge where the third limiting member 65 and the fourth limiting member 66 are located inside the collection box 100. The third guide rail 511, the fourth guide rail 512 and the second drive cylinder 513 cooperate to drive the second clamp 514 to clamp the group of products 200. The second detection module 515 identifies the third limiting member 65 and the fourth limiting member 66. The second transfer component 51 transfers the group of products 200 to the gap between the third limiting member 65 and the fourth limiting member 66.

[0075] 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 detach from the group of products 200. The second bearing member 62 of the first group of second positioning mechanisms 6 moves the thickness of the group of products 200 along the first direction. The third limiting member 65 and the fourth limiting member 66 descend. The outer wall of the fourth limiting member 66 plays the role of restricting 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 detach from the group of products 200. The second bearing member 62 of the second group of second positioning mechanisms 6 moves the thickness of the group of products 200 along the first direction. On the one hand, it restricts the products 200 already loaded in the collection box 100 to maintain a vertical state. On the other hand, it positions the loading of the next group of products 200.

[0076] S11, S9 and S10 are repeated until the collection box 100 in the unloading area 500 is fully loaded, and the unloading mechanism 92 transfers the collection box 100 to the next process.
