Description

Technical Field

[0001] The invention relates to the technical field of product sorting, and in particular to an automatic arrangement and sorting machine for diamond-shaped products. Background Art

[0002] With the development of society, people have higher and higher requirements for product quality. Before products leave the factory, they need to be tested. The arrangement of products can facilitate testing. For diamond-shaped products (such as rhinestones, zirconium diamonds, artificial diamonds, etc.), currently, the diamond-shaped products are generally arranged manually in a certain direction (generally with the upper end of the diamond-shaped products facing upwards), so that the product inspection device can detect their size and appearance to sort out unqualified products. However, this manual arrangement method is very troublesome, time-consuming and labor-intensive, which not only leads to high labor costs, but also low work efficiency.

[0003] There are also automatic arrangement and sorting machines in the prior art that can automatically arrange, inspect and sort diamond-shaped products, which include an automatic material sorting device, a product inspection device and an automatic sorting device arranged in sequence from front to back; when working, the automatic material sorting device first sorts the diamonds waiting for inspection so that they are neatly arranged in a certain direction, and then the product inspection device inspects the arranged products, and finally the unqualified products are sorted out according to the inspection results. The current automatic material sorting device generally uses a vibration plate with a certain guide mechanism to keep the arrangement of the diamond-shaped products with the tip facing upward during the vibration conveying process, and eliminates the arrangements in other directions. However, this automatic material sorting device is only suitable for large-particle diamond-shaped products with a size greater than 3mm, and cannot arrange small-particle diamond-shaped products with a size less than 3mm, and cannot guarantee the inspection results, which is prone to omissions or sorting errors. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an automatic arrangement and sorting machine for diamond-shaped products. The automatic material sorting device in the automatic arrangement and sorting machine for diamond-shaped products can automatically arrange small-particle diamond-shaped products neatly with their tips facing upward, which is conducive to accurate detection and sorting of their appearance and size, and can improve work efficiency and ensure detection results. The adopted technical solution is as follows:

[0005] An automatic sorting machine for diamond-shaped products, comprising a frame, an automatic material sorting device, a product detection device and an automatic sorting device, characterized in that: it further includes a first translation seat, a front-back translation mechanism for driving the first translation seat to translate back and forth, a detection platform and a control device. The front-back translation mechanism is installed on the frame, and the detection platform is installed on the first translation seat. The automatic material sorting device, the product detection device and the automatic sorting device are arranged in sequence from back to front and correspond to the position of the detection platform; the automatic material sorting device includes a material receiving plate, a feeding and brushing device, a left-right translation mechanism for driving the feeding and brushing device to translate left and right, a rotating seat, and a rotating mechanism for driving the rotating seat to rotate. The material receiving plate, the left-right translation mechanism, the rotating mechanism, the front-back translation mechanism and the lifting mechanism are all installed on the frame; the material receiving plate is located above the detection platform, the feeding and brushing device is arranged above the material receiving plate, and the bottom of the feeding and brushing device is matched with the top surface of the material receiving plate. The feeding and brushing device has a material accumulation cavity, and the bottom of the feeding and brushing device is provided with a discharge port and a brushing mechanism. The discharge port is communicated with the material accumulation cavity; the rotation axis of the rotating seat is arranged in the front-back direction, and at least one turning plate is installed on the rotating seat. The turning plate is located between the feeding and brushing device and the detection platform. The surface of the turning plate far from the rotation axis of the rotating seat is the first surface. A plurality of product receiving groove groups are arranged in sequence from front to back on the first surface of the turning plate. Each product receiving groove group includes at least one product receiving groove arranged in sequence from left to right. A negative pressure cavity is arranged in the turning plate, and the bottom of each product receiving groove is communicated with the negative pressure cavity; in the state where the turning plate is turned upwards, the first surface of the turning plate is connected to and in the same plane as the top surface of the material receiving plate. In the state where the turning plate is turned downwards, the first surface of the turning plate is matched with the table surface of the detection platform; the product detection device is electrically connected to the corresponding input and output terminals of the control device, and the left-right translation mechanism, the rotating mechanism, the front-back translation mechanism and the automatic sorting device are respectively electrically connected to the corresponding output terminals of the control device.

[0006] Generally, the diamond-shaped products to be detected are small-particle diamond-shaped products with a size less than 3 mm. The product receiving grooves on the turning plate match the shape and size of the diamond-shaped products. The bottom width of the product receiving groove is smaller than the width of the groove opening of the product receiving groove; one product receiving groove can accommodate one diamond-shaped product. After the diamond-shaped product completely enters the product receiving groove, the tip of the diamond-shaped product faces downwards, and the top of the diamond-shaped product is lower than the position of the groove opening of the product receiving groove.

[0007] Generally, the negative pressure cavity in the turning plate is communicated with a vacuum pumping device. The vacuum pumping device pumps air through the negative pressure cavity to generate negative pressure at the bottom of each product receiving groove, so as to adsorb the diamond-shaped products entering each product receiving groove.

[0008] In the initial state, a flipping plate can be flipped to the upper side and be located on the left or right side of the material receiving plate. The first surface of the material receiving plate is connected to the top surface of the material receiving plate and is in the same plane, and the bottom of the feeding and brushing device is matched with the top surface of the material receiving plate.During operation, first add the diamond-shaped products to be detected into the material accumulation cavity of the feeding and brushing device (at this time, the material supporting plate holds the diamond-shaped products in the material accumulation cavity); subsequently, the control device controls the left and right translation mechanism to drive the feeding and brushing device to translate from directly above the material supporting plate to directly above the turning plate, driving the diamond-shaped products in the material accumulation cavity to transfer from the top surface of the material supporting plate to the first surface of the turning plate; subsequently, the diamond-shaped products in the material accumulation cavity reciprocate back and forth along the first surface of the turning plate under the action of the brushing mechanism, causing some diamond-shaped products to enter the corresponding product receiving grooves respectively when passing through the openings of the corresponding product receiving grooves, specifically as follows: if the tip of the diamond-shaped product entering the product receiving groove is downward, the diamond-shaped product completely enters the product receiving groove, and its upper surface is lower than the position of the opening of the product receiving groove and cannot be brushed out by the brushing strip anymore; if other parts of the diamond-shaped product except its tip enter the product receiving groove first, the diamond-shaped product will partially protrude outside the opening of the product receiving groove and be brushed out of the product receiving groove under the action of the corresponding brushing strip; until corresponding diamond-shaped products are completely embedded in each product receiving groove, the left and right translation mechanism drives the first translation seat to translate and reset to directly above the material supporting plate, driving the redundant diamond-shaped products on the first surface of the turning plate that have not entered the product receiving groove to transfer to the top surface of the material supporting plate; subsequently, the rotation mechanism drives the rotating seat to rotate, driving the turning plate and the diamond-shaped products thereon to rotate 180 degrees around its rotation axis. During this process, the vacuum pumping device pumps air through the negative pressure cavity to generate negative pressure at the bottom of each product receiving groove, making the positions of the diamond-shaped products in each product receiving groove stable and preventing the diamond-shaped products from falling during the transfer process; until the first surface of the turning plate faces directly downward, the first translation seat and the detection platform are driven by the front and back translation mechanism to translate to directly below the turning plate, and the tabletop of the detection platform is brought into contact and cooperation with the first surface of the turning plate. Then, the vacuum pumping device stops pumping air, causing each diamond-shaped product to separate from the corresponding product receiving groove under its own gravity and be placed stably on the tabletop of the detection platform (at this time, the tips of each diamond-shaped product all face directly upward); subsequently, the control device controls the front and back translation mechanism to drive the first translation seat to translate from back to front, driving the detection platform and the diamond-shaped products thereon to pass through the product detection device. The control device detects the dimensions and appearance of each diamond-shaped product on the tabletop of the detection platform through the product detection device and determines the specific positions of each diamond-shaped product belonging to non-conforming products; subsequently, the control device controls the front and back translation mechanism to drive the first translation seat to continue translating from back to front, driving the detection platform and the diamond-shaped products thereon to move to the corresponding working positions of the automatic sorting device. The automatic sorting device sorts out the qualified products and non-conforming products according to the previously obtained detection results of the dimensions and appearance of each diamond-shaped product.The automatic material arranging device in this diamond-shaped product automatic arranging and sorting machine can automatically arrange small diamond-shaped products neatly with the pointed parts facing upward, facilitating accurate inspection and sorting of their appearance and dimensions by the product inspection device and the automatic sorting device, improving work efficiency, ensuring inspection results, and preventing omissions or sorting errors.

[0009] Generally, the above control device is a PLC controller or a single-chip microcomputer.

[0010] In a preferred embodiment, the front-back translation mechanism includes a first horizontal guide rail, a first screw rod, and a first translation motor. The first horizontal guide rail is installed on the frame and runs in the front-back direction. The first translation seat is installed on the first horizontal guide rail and is slidably matched with the first horizontal guide rail. The first screw rod is rotatably installed on the frame and is parallel to the first horizontal guide rail. The first translation seat is provided with a first screw hole meshing with the first screw rod. The first translation motor is installed on the frame, and the output shaft of the first translation motor is drivingly connected to the first screw rod. During operation, the first translation motor drives the first screw rod to rotate forward or backward, driving the first translation seat and the inspection platform to translate forward or backward along the first horizontal guide rail by a certain distance.

[0011] In a preferred embodiment, the left-right translation mechanism includes a second horizontal guide rail, a second translation seat, a second screw rod, and a second translation motor. The second horizontal guide rail is installed on the frame and runs in the left-right direction. The second translation seat is installed on the second horizontal guide rail and is slidably matched with the second horizontal guide rail. The second screw rod is rotatably installed on the frame and is parallel to the second horizontal guide rail. The second translation seat is provided with a second screw hole meshing with the second screw rod. The second translation motor is installed on the frame, and the output shaft of the second translation motor is drivingly connected to the second screw rod. During operation, the second translation motor drives the second screw rod to rotate forward or backward, driving the second translation seat to translate left or right along the second horizontal guide rail by a certain distance, thereby driving the feeding and brushing device to move back and forth between the flipping plate and the material receiving plate.

[0012] In a preferred embodiment, the rotation mechanism includes a rotation motor, a reducer, and a central shaft. The central shaft is rotatably installed on the frame and runs in the front-back direction. The rotation seat is fixedly installed on the central shaft. The rotation motor is installed on the frame, and the output shaft of the rotation motor is drivingly connected to the central shaft through the reducer. The axis of the central shaft is the rotation axis of the rotation seat. During operation, the rotation motor drives the central shaft to rotate, driving the rotation seat and the flipping plate thereon to rotate 180 degrees around the central shaft.

[0013] The number of the above-mentioned turnover plates can be one or more. In a specific solution, the number of the turnover plates is two, and the two turnover plates are both installed on the rotating seat and symmetrically arranged with respect to the rotation axis of the rotating seat. With this structure, when the turnover plate loaded with diamond-shaped products is turned to the lower side and cooperates with the surface of the detection platform, the other empty turnover plate is turned to the upper side and cooperates with the material receiving plate, so that the processes of arranging and placing the diamond-shaped products can be completed in parallel, and the working efficiency can be further improved.

[0014] In a preferred solution, the feeding and brushing device includes the above-mentioned brushing mechanism and a frame body. The inner cavity of the frame body forms the material accumulating cavity, the lower end of the frame body forms the discharging port, and the brushing mechanism is installed at the discharging port. During operation, diamond-shaped products to be detected can be added to the material accumulating cavity through the upper opening of the frame body.

[0015] In a further preferred solution, the automatic material sorting device further includes a brushing translation mechanism for driving the feeding and brushing device to translate back and forth. The brushing translation mechanism is installed on the power output end of the left and right translation mechanism; the brushing mechanism is composed of a plurality of brushing strips, and each brushing strip is fixedly installed at the discharging port. In this solution, the brushing mechanism uses fixedly installed brushing strips, and in cooperation with the brushing translation mechanism to drive the feeding and brushing device to reciprocate back and forth, the brushing strips move along with it, and brush the diamond-shaped products into or out of the product accommodating groove. In this way, the brushing mechanism is simplified to a powerless brushing strip; in other solutions, the brushing mechanism can adopt independent driving, for example, a reciprocating driving device is used in the discharging port to drive a plurality of brushing strips to move simultaneously to brush the diamond-shaped products into or out of the product accommodating groove. In this case, there is no need to set up a brushing translation mechanism.

[0016] In a further preferred solution, the material of the brushing strip is rubber, sponge or other foaming materials. In this way, the material of the brushing strip can be made soft and have a certain elasticity. After the brushing strip contacts or squeezes the diamond-shaped product, it will deform accordingly, which can effectively prevent the brushing strip from hitting the diamond-shaped product and damaging the surface of the diamond-shaped product, and can reduce the noise generated during the material sorting process.

[0017] In a further preferred solution, the brush material translation mechanism includes a third horizontal guide rail, a third translation seat, a third screw rod, and a third translation motor. The third horizontal guide rail is installed on the power output end of the left-right translation mechanism and extends in the front-back direction. The third translation seat is installed on the third horizontal guide rail and is slidably matched with the third horizontal guide rail. The third screw rod is rotatably installed on the power output end of the left-right translation mechanism and is parallel to the third horizontal guide rail. The third translation seat is provided with a third threaded hole meshing with the third screw rod. The feeding and brushing device is installed on the third translation seat. The third translation motor is installed on the third translation seat, and the output shaft of the third translation motor is in transmission connection with the third screw rod. During operation, the third translation motor drives the third screw rod to rotate forward or backward, driving the third translation seat and the feeding and brushing device to translate forward or backward along the third horizontal guide rail by a certain distance.

[0018] In a further preferred solution, the brushing mechanism is a brushing bottom plate. The brushing bottom plate is installed on the lower end surface of the discharge port. A plurality of strip-shaped holes are formed in the brushing bottom plate. The strip-shaped holes and the material receiving plate or the flipping plate form a material accumulation groove, and the partition between two adjacent strip-shaped holes forms the brushing strip. When the strip-shaped holes and the flipping plate form a material accumulation groove, a large number of diamond-shaped products are accumulated in the material accumulation groove. As long as the brush material translation mechanism drives the frame of the feeding and brushing device to move back and forth several times, there are always diamond-shaped products in the correct direction that are brushed into the product receiving groove by the brushing strip.

[0019] In a still further preferred solution, the brushing bottom plate is a rubber plate. The brushing bottom plate is set as a rubber plate, which can make the material of the brushing strip soft and have a certain elasticity. The brushing strip will deform accordingly after contacting or squeezing with the diamond-shaped products, which can effectively prevent the brushing strip from hitting the diamond-shaped products and causing damage to the surface of the diamond-shaped products, and can reduce the noise generated during the material sorting process.

[0020] The above-mentioned first translation motor, second translation motor, third translation motor, and rotation motor can adopt servo motors or stepper motors.

[0021] In a preferred solution, the product detection device is a vision detection camera. The vision detection camera is located above the detection platform and its lens is set downward. The detection platform can pass through the shooting area of the vision detection camera lens. During operation, the control device controls the front-back translation mechanism to drive the first translation seat to translate from the back to the front, driving the detection platform and each diamond-shaped product thereon to pass through the shooting area of the vision detection camera lens. The control device controls the vision detection camera to take pictures of each diamond-shaped product on the tabletop of the detection platform, and conducts image comparison and analysis to obtain the detection results of the size and appearance of each diamond-shaped product on the tabletop of the detection platform, and determines the specific positions of each diamond-shaped product that belongs to unqualified products.

[0022] In a preferred embodiment, the automatic sorting device includes a lifting seat, a lifting mechanism for driving the lifting seat to move up and down, a qualified product collection container, a defective product collection container, and at least one sorting mechanism; the detection platform, the qualified product collection container, the defective product collection container, and the sorting mechanism are all installed on the first translation seat. The lifting seat is arranged in front of the product detection device. A plurality of blanking partitions are arranged on the lifting seat in sequence from back to front. Each blanking partition is located above the detection platform and cooperates with the platform surface of the detection platform; the sorting mechanism is located below the front end of the detection platform. The number of product receiving slots of the sorting mechanism is the same as that of the product receiving slots of the product receiving slot group and the positions correspond one by one. The qualified product collection container and the defective product collection container are located at the corresponding positions below or in front of the sorting mechanism. During operation, the control device controls the front and back translation mechanism to drive the first translation seat, the detection platform, and each diamond-shaped product thereon to move to the corresponding working position of the automatic sorting device and then pauses the movement; then, the control device controls the lifting mechanism to drive the lifting seat to descend, so that the lower ends of each blanking partition reach a position close to the platform surface of the detection platform, and the lower ends of each blanking partition are respectively located between two adjacent diamond-shaped product groups; then, the control device controls the front and back translation mechanism to drive the first translation seat, the detection platform, the defective product collection container, the qualified product collection container, and the sorting mechanism thereon to slowly translate backward, so that each blanking partition moves relative to the detection platform, and each blanking partition respectively pushes the corresponding diamond-shaped product group to translate forward, so that each diamond-shaped product group falls from the front end of the detection platform one by one; during this process, the control device controls whether each sorting mechanism operates according to the previously obtained detection results of each diamond-shaped product in terms of size and appearance, and sorts each qualified product and each defective product into the qualified product collection container and the defective product collection container respectively.

[0023] In a further preferred embodiment, the lifting mechanism includes a lifting cylinder. The cylinder body of the lifting cylinder is installed on the frame, and the piston rod of the lifting cylinder faces downward and is connected to the lifting seat. During operation, the piston rod of the lifting cylinder can be extended or retracted to drive the lifting seat to rise or fall by a certain height.

[0024] In a further preferred embodiment, the qualified product collection container is located directly below the front end of the detection platform, and the collection port of the qualified product collection container is arranged upward; the defective product collection container and the sorting mechanism are arranged between the detection platform and the qualified product collection container, and the defective product collection container and the sorting mechanism are respectively located on the front and back sides of the qualified product collection container, and the sorting mechanism faces the collection port of the defective product collection container.

[0025] In a further preferred embodiment, the sorting mechanism includes a blowing pipe and an air valve. The blowing pipe is installed on the translation seat, and the air outlet end of the blowing pipe faces forward and is directly opposite to the collection port of the defective product collection container. The air valve is installed on the blowing pipe and is electrically connected to the corresponding output end of the control device. Usually, the air inlet end of the blowing pipe is communicated with the air outlet of the hair dryer. During operation, if there are defective products in the diamond-shaped product group that fall from the front end of the detection platform, the control device controls the air valve of the corresponding sorting mechanism to open, and the hair dryer blows air through the blowing pipe towards the collection port of the defective product collection container, blowing the defective products into the defective product collection container during the falling process of the defective products.

[0026] In another further preferred embodiment, the sorting mechanism includes a pushing block and a pushing translation mechanism for driving the pushing block to reciprocate back and forth. The pushing block is located behind the defective product collection container and is directly opposite to the collection port of the defective product collection container.

During operation, the pushing translation mechanism drives the pushing block to translate forward, impacts the falling defective products through the pushing block, and pushes them into the defective product collection container; then drives the pushing block to move backward to reset and waits for the next defective product.

[0027] In a still further preferred embodiment, the pushing translation mechanism includes a translation cylinder. The cylinder body of the translation cylinder is installed on the frame and is in the front-back direction, and the piston rod of the translation cylinder is connected to the pushing block.

During operation, the third translation motor 174 drives the third screw rod 173 to rotate forward or reversely, thereby driving the third translation seat 172 and the feeding brush 12 to translate forward or backward a certain distance along the third horizontal guide rail 171 .

[0043] In this embodiment, the brushing mechanism 121 is a brushing bottom plate 1212. The brushing bottom plate 1212 is installed on the lower end face of the discharge port 1202, and the brushing bottom plate 1212 is a rubber plate. A plurality of strip-shaped holes 12121 are formed in the brushing bottom plate 1212. The strip-shaped holes 12121 and the material receiving plate 11 or the turning plate 16 form a material accumulating groove 1203, and the separating part 12122 between two adjacent strip-shaped holes 12121 forms a brushing strip 1211. When the strip-shaped holes 12121 and the turning plate 16 form the material accumulating groove 1203, a large number of diamond-shaped products are accumulated in the material accumulating groove 1203. As long as the brushing translation mechanism 17 drives the frame 122 of the feeding and brushing device 12 to move back and forth several times, the diamond-shaped products in the correct direction are always brushed into the product receiving groove 162 by the brushing strip 1211. The brushing bottom plate 1212 is set as a rubber plate, which can make the material of the brushing strip 1211 soft and have a certain elasticity. The brushing strip 1211 will deform correspondingly after contacting or squeezing the diamond-shaped products, which can effectively prevent the brushing strip 1211 from hitting the diamond-shaped products and damaging the surface of the diamond-shaped products, and can reduce the noise generated during the material sorting process.

[0044] In this embodiment, the product detection device 2 is a vision detection camera 21. The vision detection camera 21 is located above the detection platform 6 and its lens 211 is arranged downward, and the detection platform 6 can pass through directly below the lens 211 of the vision detection camera 21.

[0045] The automatic sorting device 3 includes a lifting seat 31, a lifting mechanism 32 for driving the lifting seat 31 to lift, a qualified product collection container 34, an unqualified product collection container 35, and a plurality of sorting mechanisms 36. The detection platform 6, the qualified product collection container 34, the unqualified product collection container 35, and each sorting mechanism 36 are all installed on the first translation seat 4. The lifting seat 31 is arranged in front of the product detection device 2. A plurality of blanking partition plates 311 are arranged on the lifting seat 31 in sequence from back to front. Each blanking partition plate 311 is located above the detection platform 6 and cooperates with the platform surface of the detection platform 6. Each sorting mechanism 36 is located below the front end of the detection platform 6. The number of sorting mechanisms 36 is the same as the number of product receiving grooves 162 in the product receiving groove group and their positions correspond one by one. The qualified product collection container 34 and the unqualified product collection container 35 are located at the corresponding positions below or in front of the sorting mechanism 36.

[0046] In this embodiment, the lifting mechanism 32 includes a lifting cylinder 321. The cylinder body of the lifting cylinder 321 is installed on the frame, and the piston rod of the lifting cylinder 321 faces downward and is connected to the lifting seat 31. During operation, the piston rod of the lifting cylinder 321 can be extended or retracted to drive the lifting seat 31 to rise or fall by a certain height.

[0047] In this embodiment, the qualified product collection container 34 is directly below the front end of the detection platform 6, and the collection port 3401 of the qualified product collection container 34 is arranged upward; the unqualified product collection container 35 and each sorting mechanism 36 are arranged between the detection platform 6 and the qualified product collection container 34, and the unqualified product collection container 35 and each sorting mechanism 36 are respectively located on the front and rear sides of the qualified product collection container 34, and the sorting mechanism 36 faces the collection port 3501 of the unqualified product collection container 35; the sorting mechanism 36 includes a blowing pipe 361 and an air valve 362. The blowing pipe 361 is installed on the translation seat, the air outlet end of the blowing pipe 361 faces forward and is directly opposite to the collection port 3501 of the unqualified product collection container 35, and the air valve 362 is installed on the blowing pipe 361. The air valve 362 is electrically connected to the corresponding output end of the control device 7. The intake ends of the blowing pipes 361 are all communicated with the air outlet of the hair dryer. During operation, if there are unqualified products in the diamond-shaped product group falling from the front end of the detection platform 6, the control device 7 controls the air valve 362 of the corresponding sorting mechanism 36 to open, and the hair dryer blows air through the blowing pipe 361 towards the collection port 3501 of the unqualified product collection container 35, and blows the unqualified products into the unqualified collection container 35 during the falling process of the unqualified products.

[0048] The working principle of this diamond-shaped product automatic alignment and sorting machine is briefly described below:

[0049] The diamond-shaped products to be detected are small-particle diamond-shaped products with a size less than 3 mm. The product accommodation grooves 162 on the turning plate 16 match the shape and size of the diamond-shaped products. The bottom width of the product accommodation groove 162 is less than the width of the groove opening of the product accommodation groove 162; one product accommodation groove 162 can accommodate one diamond-shaped product. After the diamond-shaped product completely enters the product accommodation groove 162, the tip of the diamond-shaped product faces downward, and the top of the diamond-shaped product is lower than the position of the groove opening of the product accommodation groove 162. The negative pressure chamber 163 in the turning plate 16 is communicated with a vacuum pumping device. The vacuum pumping device pumps air through the negative pressure chamber 163 to generate negative pressure at the bottom of each product accommodation groove 162, so as to adsorb the diamond-shaped products entering each product accommodation groove 162.

[0050] In the initial state, a flipping plate 16 can be flipped upward and located on the left or right side of the material receiving plate 11. The first surface 161 of the material receiving plate 11 is connected to the top surface of the material receiving plate 11 and lies in the same plane. The bottom of the feeding and brushing device 12 is matched with the top surface of the material receiving plate 11. During operation, first, diamond-shaped products to be detected are added into the material accumulation cavity 1201 of the feeding and brushing device 12 through the upper opening of the frame body 122 (at this time, the material receiving plate 11 supports the diamond-shaped products in the material accumulation cavity 1201); subsequently, the control device 7 controls the left and right translation mechanism 13 to drive the feeding and brushing device 12 to translate from directly above the material receiving plate 11 to directly above the flipping plate 16, driving the diamond-shaped products in the material accumulation cavity 1201 to be transferred from the top surface of the material receiving plate 11 to the first surface 161 of the flipping plate 16; subsequently, the diamond-shaped products in the material accumulation cavity 1201 reciprocate back and forth along the first surface 161 of the flipping plate 16 under the action of the brushing mechanism 121, enabling some diamond-shaped products to enter the corresponding product receiving grooves 162 respectively when passing through the openings of the corresponding product receiving grooves 162, specifically as follows: if the tip of the diamond-shaped product entering the product receiving groove 162 faces downward, the diamond-shaped product completely enters the product receiving groove 162, and its upper surface is lower than the opening position of the product receiving groove 162 and cannot be brushed out by the brushing strip 1211 anymore; if other parts of the diamond-shaped product except its tip enter the product receiving groove 162 first, the diamond-shaped product will partially protrude outside the opening of the product receiving groove 162 and be brushed out of the product receiving groove 162 under the action of the corresponding brushing strip 1211; until corresponding diamond-shaped products are completely embedded in each product receiving groove 162, the left and right translation mechanism 13 drives the first translation seat 4 to translate and reset to directly above the material receiving plate 11, driving the excess diamond-shaped products on the first surface 161 of the flipping plate 16 that have not entered the product receiving grooves 162 to be transferred to the top surface of the material receiving plate 11; subsequently, the rotation mechanism 15 drives the rotation seat 14 to rotate, driving the flipping plate 16 and the diamond-shaped products thereon to flip 180 degrees around its rotation axis. During this process, the vacuum pumping device pumps air through the negative pressure cavity 163 to generate negative pressure at the bottom of each product receiving groove 162, making the diamond-shaped products in each product receiving groove 162 stable in position and preventing the diamond-shaped products from falling during the transfer process; until the first surface 161 of the flipping plate 16 faces directly downward, the front and back translation mechanism 5 drives the first translation seat 4 and the detection platform 6 to translate to directly below the flipping plate 16, and the table surface of the detection platform 6 is in contact and cooperation with the first surface 161 of the flipping plate 16. Then, the vacuum pumping device stops pumping air, enabling each diamond-shaped product to separate from the corresponding product receiving groove 162 under its own gravity and be placed stably on the table surface of the detection platform 6 (at this time, the tips of each diamond-shaped product face directly upward);Subsequently, the control device 7 controls the front-back translation mechanism 5 to drive the first translation base 4 to translate from the rear to the front, driving the inspection platform 6 and each diamond-shaped product thereon to pass through the shooting area of the lens 211 of the vision inspection camera 21. The control device 7 uses the vision inspection camera 21 to shoot each diamond-shaped product on the surface of the inspection platform 6, and conducts image comparison and analysis to obtain the inspection results of each diamond-shaped product on the surface of the inspection platform 6 in terms of size and appearance, and determines the specific positions of each diamond-shaped product belonging to non-conforming products; Subsequently, the control device 7 controls the front-back translation mechanism 5 to drive the first translation base 4, the inspection platform 6 and each diamond-shaped product thereon to move to directly below the lifting base 31 and then pauses the movement; Next, the control device 7 controls the lifting mechanism 32 to drive the lifting base 31 to descend, so that the lower ends of each blanking partition 311 reach a position close to the surface of the inspection platform 6, and the lower ends of each blanking partition 311 are respectively located between two adjacent diamond-shaped product groups; Then, the control device 7 controls the front-back translation mechanism 5 to drive the first translation base 4, the inspection platform 6 thereon, the non-conforming product collection container 35, the conforming product collection container 34 and each sorting mechanism 36 to translate backward slowly, so that each blanking partition 311 moves relative to the inspection platform 6, and each diamond-shaped product group is pushed forward by each blanking partition 311 respectively, so that each diamond-shaped product group drops from the front end of the inspection platform 6 one by one; During this process, the control device 7 controls whether each sorting mechanism 36 operates according to the inspection results of each diamond-shaped product in terms of size and appearance obtained previously, and sorts each conforming product and each non-conforming product into the conforming product collection container 34 and the non-conforming product collection container 35: If all the diamond-shaped product groups dropping from the front end of the inspection platform 6 are conforming products, the control device 7 controls each sorting mechanism 36 not to operate, and these diamond-shaped products will all drop into the conforming product collection container 34; If there are non-conforming products in the diamond-shaped product groups dropping from the front end of the inspection platform 6, the control device 7 controls the corresponding sorting mechanisms 36 to operate according to the specific positions of the diamond-shaped products belonging to non-conforming products obtained previously, pushes the non-conforming products into the non-conforming product collection container 35 during the dropping process of the non-conforming products, and makes the remaining sorting mechanisms 36 not operate, so that the conforming products in the diamond-shaped product group drop into the conforming product collection container 34.
