In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] In the production process, in order to classify the products, please refer to Figures 1 to 12 , the present embodiment provides a product classification device, which includes a loading mechanism 1, a first transfer mechanism 2, a code scanning mechanism, a second transfer mechanism 4 and a material unloading mechanism 5, the loading mechanism 1 is configured to convey the product to be classified to the loading station, the first transfer mechanism 2 is configured to transfer the product from the loading station to the code scanning station, the code scanning mechanism is arranged at the code scanning station, the code scanning mechanism includes a code scanner 31 and a classification table 32, the code scanner 31 is configured to scan the identification code on the product, so as to identify the category of the product, the classification table 32 is divided into four placement areas 321, and the four placement areas 321 respectively store products of different categories, the second transfer mechanism 4 can transfer the product to different placement areas 321 according to the scanning result according to the category, and can transfer all products in any placement area 321 to the unloading station after any placement area 321 is full of products, the unloading mechanism 5 is arranged at the unloading station, the unloading mechanism 5 includes four unloading areas 512, and the second transfer mechanism 4 can place the product in different unloading areas 512 according to the category.

[0045] Specifically, taking a watch case as an example, the case is composed of an outer shell and a watch mirror, and the outer shell and the watch mirror are bonded by a fixing glue. During the production process of the case, the fixing glue needs to be cured by an oven, and the case removed from the oven flows to the product classification device for classification. From above, the loading mechanism 1 transports the case removed from the oven to the loading station, and the first transfer mechanism 2 transfers the case to the code scanning station for scanning, so as to identify the category of the case according to the identification code on the case, and then the second transfer mechanism 4 places the case into the corresponding placement area 321 according to the scanning result. For any placement area 321, after the placement area 321 is full of cases, the second transfer mechanism 4 will transfer all the cases in the placement area 321 to the corresponding unloading area 512 for unloading.

[0046] Based on the above, the present embodiment supplies the products to be classified to the code scanning mechanism through the feeding mechanism 1 and the first transfer mechanism 2, and the code scanning mechanism accurately identifies the category of the product through the code scanner 31. In addition, the present embodiment places the scanned products in the corresponding placement area 321 according to the category through the second transfer mechanism 4, and after any placement area 321 is full of products, the second transfer mechanism 4 can simultaneously transfer all the products in the placement area 321 to the corresponding unloading area 512 for unloading. From the above, the product classification device in the present embodiment can realize the automatic classification of products with high work efficiency, and the product classification device can accurately classify the products by scanning the code with the code scanner 31 to identify the category of the product.

[0047] It is understandable that in other optional embodiments, the classification table 32 may also be divided into two, three, five or other number of placement areas 321, and the number of placement areas 321 is specifically determined by the number of product categories, and this embodiment does not impose any specific restrictions on this. Correspondingly, in other optional embodiments, the unloading mechanism 5 may also be configured to include two, three, five or other number of unloading areas 512, and the number of unloading areas 512 is specifically determined by the number of product categories, and this embodiment does not impose any specific restrictions on this.

[0048] It is worth noting that, exemplarily, in the present embodiment, the feeding mechanism 1 is a feeding conveyor line, and the feeding conveyor line is used to convey the product to the feeding station.

[0049] In addition, the code scanning mechanism also includes two first conveyor lines 33, all of which are correspondingly provided with a first transfer mechanism 2, the first conveyor line 33 includes two conveyor line bodies 331, all of which are provided with a first carrier 332, and the two ends of the conveyor line body 331 are respectively a first loading position 3311 and a first unloading position 3312. The first transfer mechanism 2 can transfer the product to the first carrier 332 located at the first loading position 3311, and the conveyor line body 331 can drive the first carrier 332 to move between the first loading position 3311 and the first unloading position 3312, so that the first carrier 332 can receive the product from the first loading position 3311 and convey the product to the first unloading position 3312.

[0050] Furthermore, the code scanning mechanism also includes a transport module 34 and a code scanning platform 35. The transport module 34 can transport the product from the first carrier 332 located at the first unloading position 3312 to the code scanning platform 35. The code scanner 31 can scan the product located at the code scanning platform 35 to identify the category of the product.

[0051] As described above, in the present embodiment, a single first conveyor line 33 is provided with two conveyor line bodies 331, thereby reducing the standby time of the first transfer mechanism 2, and further improving the working efficiency of the product classification device. For example, for the two first carriers 332 respectively arranged on the two conveyor line bodies 331, when one of the first carriers 332 receives the product at the first loading position 3311, the other first carrier 332 can move from the first loading position 3311 to the first unloading position 3312, and complete the unloading at the first unloading position 3312, and then return to the first loading position 3311. Therefore, after one of the first carriers 332 is full of products, the first transfer mechanism 2 can quickly switch to transfer products to the other first carrier 332.

[0052] Moreover, in the present embodiment, two first conveyor lines 33 are provided, thereby reducing the standby time of the transport module 34 and further improving the working efficiency of the product classification device. In the present embodiment, for the four conveyor line bodies 331, the four first carriers 332 can be moved to the first unloading position 3312 in sequence, and the transport module 34 can take products from the four first carriers 332 in sequence. After one of the first carriers 332 is empty, the transport module 34 can quickly switch to taking products from another first carrier 332.

[0053] It can be understood that in other optional embodiments, the code scanning mechanism can be configured to include three or more first conveyor lines 33, the first conveyor line 33 can be configured to include three or more conveyor line bodies 331, and the number of first conveyor lines 33 and the number of conveyor line bodies 331 included in a single first conveyor line 33 are specifically set according to the actual working conditions of the first transfer mechanism 2 and the handling module 34, and this embodiment does not impose any specific restrictions on this.

[0054] Furthermore, the first carrier 332 is provided with two rows of first loading positions 3321, and exemplarily, four first loading positions 3321 form a row, the code scanning station 35 includes a second conveyor line 351, and two second carriers 352 are provided on the second conveyor line 351. The second carrier 352 is provided with a row of second loading positions 3521, and exemplarily, four second loading positions 3521 form a row. The second conveyor line 351 can drive the two second carriers 352 to move to the second loading position 3511 in sequence, and the handling module 34 can take two rows of products from the first carrier 332, and can place the two rows of products into the two second carriers 352 row by row, and the second conveyor line 351 can also It is capable of driving the two second carriers 352 to move to the second unloading position 3512 in sequence. The barcode scanner 31 is arranged at the second unloading position 3512. The barcode scanner 31 is capable of scanning a row of products at the same time. Specifically, the identification code is arranged on the periphery of the product. Four through holes 3522 are arranged on the second carrier 352. The four through holes 3522 correspond one-to-one to the four second loading positions 3521, thereby exposing the identification codes of the four products loaded on the second carrier 352. The barcode scanner 31 includes four scanning terminals 311. After the second carrier 352 moves to the second unloading position 3512, the four through holes 3522 are opposite to the four scanning terminals 311 one-to-one, thereby being capable of scanning a row of products at the same time.

[0055] From the above, since this embodiment can scan the codes of a row of products at one time, thereby identifying the categories of a row of products at one time, this embodiment can further improve the working efficiency of the product classification device.

[0056] It is understandable that in other optional embodiments, the first carrier 332 may also be configured to include three or more rows of first loading positions 3321. Correspondingly, three or more second carriers 352 are arranged on the second conveyor line 351. The number of second carriers 352 arranged on the second conveyor line 351 is equal to the number of rows of first loading positions 3321 set by a single first carrier 332. This embodiment does not impose specific restrictions on the number of rows of first loading positions 3321 set by a single first carrier 332 and the number of second carriers 352 set on the second conveyor line 351.

[0057] From the above, in the present embodiment, the first transfer mechanism 2 includes a first transfer module 21 and a first handling module 22. The first transfer module 21 can drive the first handling module 22 to move between the loading station and the code scanning station. The first handling module 22 includes two first handling members 221, so that the first handling module 22 can absorb two products at a time and place the two products in two rows of first loading positions 3321 respectively, that is, the first handling module 22 can place one product in each of the two rows of first loading positions 3321 at a time, thereby improving the working efficiency of the first transfer mechanism 2, and further improving the working efficiency of the product classification device.

[0058] It is understandable that, in other optional embodiments, if the first carrier 332 is configured to include three or more rows of first loading positions 3321, correspondingly, the first handling module 22 is configured to include three or more first handling members 221, and the number of first handling members 221 is equal to the number of rows of first loading positions 3321 set by a single first carrier 332, and this embodiment does not impose any specific restrictions on this.

[0059] It is worth noting that in this embodiment, the first handling member 221 is a suction cup, so that it can suck up the product. Of course, in other optional embodiments, the first handling member 221 can also be a pneumatic clamp or a pneumatic chuck or other structures that can be used to carry products. This embodiment does not impose specific restrictions on this.

[0060] Based on the content mentioned above, for the products transported to the loading station by the loading mechanism 1, since the postures of any two products may be the same or different, the products need to be transported to the code scanning station in a specific posture to ensure that the scanner 31 can accurately scan the identification code on the product. Specifically, the products need to be transported to the first carrier 332 in a specific posture to ensure that for the products subsequently transported to the second carrier 352 by the transport module 34, the identification code of the product can be exposed from the through hole 3522.

[0061] To this end, in the present embodiment, the product classification device also includes a first visual inspection module 61, and the first transfer module 21 can drive the first handling module 22 to move from the loading station to the first visual inspection module 61 and the code scanning station in sequence, and the first visual inspection module 61 can obtain the image of the product transported by the first handling module 22. The first transfer module 21 can also drive the first handling module 22 to rotate, and the rotation axis 23 is perpendicular to the side of the first handling module 22 facing the product, that is, the rotation axis 23 is perpendicular to the adsorption surface of the first handling member 221, so that the first transfer module 21 can adjust the posture of the product transported by the first handling module 22.

[0062] Specifically, the first visual inspection module 61 is arranged on one side of the loading conveyor line, and the first transfer mechanism 2 can drive the product to pass through the field of view of the first visual inspection module 61. For the product conveyed to the loading station, if the product is in a preset posture, then after being detected by the first visual inspection module 61, the first transfer module 21 directly drives the first handling module 22 to place the product in the first carrier 332. If the product is deflected relative to the preset posture, then after being detected by the first visual inspection module 61, the first transfer module 21 drives the first handling module 22 to rotate, and after accurately correcting the posture of the product, the product is placed in the first carrier 332.

[0063] However, since the first handling module 22 in this embodiment carries two products at a time, if both products are in a preset posture, the two products can be directly placed in the first carrier 332. However, if only one of the two products is in the preset posture, or both products are deflected relative to the preset posture, it is necessary to correct the posture of the single product. For this reason, in this embodiment, the first handling module 22 also includes a first driving unit 222, and all first handling members 221 are correspondingly provided with a first driving unit 222, and the first driving unit 222 is used to drive the first handling member 221 to move in a direction perpendicular to the adsorption surface of the first handling member 221. For the two products picked up by the first handling module 22, if the postures of the two products are deflected relative to the preset posture, the posture of one of the products is corrected first. Specifically, the first transfer module 21 drives the first handling module 22 to rotate and accurately corrects the posture of the product. After that, the product is moved in a direction perpendicular to the adsorption surface of the first handling member 221 to place the product in the first carrier 332. Then, the posture of the other product is corrected, and after correction, the product is placed in the first carrier 332 by moving the product in a direction perpendicular to the adsorption surface of the first handling member 221.

[0064] Similarly, if only one of the two products has a posture that is deflected relative to the preset posture, the product in the preset posture is first placed in the first carrier 332, and then the posture of the other product is corrected and placed in the first carrier 332 after correction.

[0065] It is worth noting that, in this embodiment, the first transfer module 21 is a robot. Of course, in other optional embodiments, the first transfer module 21 can also be a driving structure composed of a three-axis moving module and a rotating module, and this embodiment does not impose specific restrictions on this.

[0066] It is also worth noting that the first driving part 222 can be selected as a linear driving structure such as a cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0067] In addition, for the products conveyed to the loading station, there is a problem of posture deviation for the upright products, but in addition to this, there is also a problem of the products being placed upside down. For this reason, in addition to the first visual inspection module 61, the product classification device also includes a second visual inspection module 62. The second visual inspection module 62 is configured to obtain images of the products conveyed to the loading station. Exemplarily, the second visual inspection module 62 is arranged at the loading station and is located directly above the loading conveyor line. The second visual inspection module 62 is electrically connected to the first transfer mechanism 2, so that the first transfer mechanism 2 only moves products that are placed upright.

[0068] For the products placed upside down, the product classification device further includes a material unloading conveyor line 9, and the material loading conveyor line can convey the products placed upside down to the material unloading conveyor line 9, thereby unloading the products placed upside down.

[0069] It is understandable that a transition conveyor line (not shown in the figure) is provided between the loading conveyor line and the unloading conveyor line 9. Since the specific structure of the transition conveyor line is prior art, it will not be described in detail in this embodiment.

[0070] Furthermore, the transport module 34 includes a second transfer module 341 and a second handling module 342. The second transfer module 341 is configured to drive the second handling module 342 to move along the first horizontal direction and the vertical direction. The first unloading position 3312 and the second loading position 3511 are arranged at intervals along the first horizontal direction. After the first carrier 332 moves to the first unloading position 3312, the two rows of first loading positions 3321 are arranged along the second horizontal direction perpendicular to the first horizontal direction. From the above, the second transfer module 341 can first drive the second handling module 342 to move along the first horizontal direction to above the first unloading position 3312, and then the second transfer module 341 drives the second handling module 342 to descend in the vertical direction so that the second handling module 342 can carry two rows of products, and then, the second transfer module 341 drives the second handling module 342 to rise in the vertical direction and move along the first horizontal direction so that the second handling module 342 moves to above the second loading position 3511, and then, the second transfer module 341 drives the second handling module 342 to descend in the vertical direction to place the two rows of products row by row into the two second carriers 352.

[0071] The two second carriers 352 are arranged in a row along the second horizontal direction. The code scanning station 35 also includes a movable plate 353. All the second carriers 352 are correspondingly provided with a movable plate 353. The second conveyor line 351 is configured to drive the movable plate 353 to move along the second horizontal direction. One of the movable plates 353 is fixed in the vertical direction, and the remaining movable plates 353 can move in the vertical direction, so that the two movable plates 353 can be moved alternately to the second loading position 3511. Specifically, when the two movable plates 353 move toward each other and intersect, one of the movable plates 353 descends in the vertical direction to avoid the other movable plate 353.

[0072] Moreover, one of the second carriers 352 is fixedly connected to the movable plate 353, and the other second carriers 352 are slidably connected to the movable plate 353 along the second horizontal direction, so that the two second carriers 352 can be moved respectively to directly below the two rows of products handled by the second handling module 342, and then the second handling module 342 can place the two rows of products in the two second carriers 352 respectively. By way of example, for the second carrier 352 whose position is fixed relative to the movable plate 353, the second carrier 352 is located directly below the first row of products when it moves to the second loading position 3511. For the second carrier 352 that can slide relative to the movable plate 353, the second carrier 352 will adjust its position when it moves to the second loading position 3511 so as to be located directly below the second row of products.

[0073] Specifically, in this embodiment, the second conveyor line 351 includes a conveyor belt 3513 and a driving motor (not shown in the figure) for driving the conveyor belt 3513 to operate, wherein one movable plate 353 is fixedly connected to the upper belt body of the conveyor belt 3513, the lower belt body of the conveyor belt 3513 is fixedly connected to the connecting plate 3514, and the other movable plate 353 is slidably connected to the connecting plate 3514 along the vertical direction. The conveyor belt 3513 can drive the two movable plates 353 to move between the second upper material position 3511 and the second lower material position 3512.

[0074] In addition, exemplarily, in the present embodiment, the second conveyor line 351 also includes a guide plate 3515, and a guide hole 35151 is provided on the guide plate 3515. The guide hole 35151 is higher at one end close to the second loading position 3511 and the other end close to the second unloading position 3512, and the middle position of the guide hole 35151 is lower. For the movable plate 353 that can move in the vertical direction, a connecting rod 3532 is fixedly connected to its bottom, and the end of the connecting rod 3532 away from the movable plate 353 is slidably connected to the guide hole 35151. When the movable plate 353 moves from the second loading position 3511 to the second unloading position 3512 or from the second unloading position 3512 to the second loading position 3511, the end of the connecting rod 3532 away from the movable plate 353 can roll along the guide hole 35151 and drive the movable plate 353 to first descend and then rise in the vertical direction.

[0075] It can be understood that after the second carrier 352 moves to the second unloading position 3512, the barcode scanner 31 is opposite to the through hole 3522 on the second carrier 352 along the second horizontal direction, so that the product on the second carrier 352 can be scanned through the through hole 3522. For the second carrier 352 whose position is fixed relative to the movable plate 353, each time the second carrier 352 moves to the second unloading position 3512, the distance between the product on the second carrier 352 and the barcode scanner 31 along the second horizontal direction is fixed, and the distance is a reference value. The barcode scanner 31 can accurately scan the product on the second carrier 352 whose distance is equal to the reference value, and for the product that can be For the second carrier 352 that slides relative to the movable plate 353, since the second carrier 352 will adjust its position when moving to the second loading position 3511, each time the second carrier 352 moves to the second unloading position 3512, the distance between it and the barcode scanner 31 is not equal to the reference value. However, in order to ensure that the barcode scanner 31 can accurately scan the products on any second carrier 352, in this embodiment, for the second carrier 352 that can slide relative to the movable plate 353, the second carrier 352 will adjust its position when moving to the second unloading position 3512 until the distance between it and the barcode scanner 31 along the second horizontal direction is equal to the reference value.

[0076] Specifically, the second carrier 352 is fixedly connected to one of the moving plates 353 , and the second driving unit 3531 is installed on the other moving plates 353 . The second driving unit 3531 is used to drive the second carrier 352 installed on the moving plate 353 to move along the second horizontal direction.

[0077] It is understandable that the second driving part 3531 can be selected as a linear driving structure such as a cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0078] It can also be understood that, in the present embodiment, the second transfer module 341 is composed of a KK module and a driving cylinder. Of course, in other optional embodiments, the second driving part 3531 may also be composed of two KK modules or two driving cylinders, and the present embodiment does not impose any specific restrictions on this.

[0079] In addition, the second handling module 342 includes a second handling member 3421 and a third driving unit 3422. The second handling member 3421 is arranged in two rows, and any row is provided with four second handling members 3421. The two rows of second handling members 3421 are arranged along the second horizontal direction, and the two rows of second handling members 3421 are respectively provided with a third driving unit 3422. The third driving unit 3422 is used to drive a row of second handling members 3421 to rise and fall in the vertical direction, so that the second handling module 342 can simultaneously carry all products on the first carrier 332, and can place the two rows of products in the two second carriers 352 respectively.

[0080] The third driving part 3422 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0081] In addition, in this embodiment, the second handling member 3421 is a suction cup, so that it can suck up the product. Of course, in other optional embodiments, the second handling member 3421 can also be a pneumatic clamp or a pneumatic chuck or other structures that can be used to handle products. This embodiment does not impose specific restrictions on this.

[0082] Furthermore, the placement area 321 is provided with four third loading positions 3211, and the number of the third loading positions 3211 in the placement area 321 is the same as the number of the second loading positions 3521 on the second carrier 352, thereby meeting the working requirements of the second transfer mechanism 4. The second transfer mechanism 4 includes a third transfer module 41 and a third handling module 42. The third transfer module 41 can drive the third handling module 42 to move between the second unloading position 3512 and the classification table 32, thereby transporting the product from the second carrier 352 to the classification table 32. Specifically, the third handling module 42 includes a first driving member 421 and a third handling member 422, wherein the number of the third handling members 422 is specifically set according to the number of the second loading positions 3521 set on the second carrier 352. By way of example, in this embodiment, the third handling module 42 includes four third handling members 42 2. The four third handling members 422 correspond one by one to the four second loading positions 3521 on the second carrier 352. All the third handling members 422 are correspondingly provided with a first driving member 421. The first driving member 421 is configured to drive the third handling members 422 to rise and fall in the vertical direction, that is, all the third handling members 422 can be lifted and lowered individually. On the one hand, all the third handling members 422 can synchronously pick up products from the second carrier 352 located at the second unloading position 3512. On the other hand, after the third handling module 42 moves to the classification table 32, the third transfer module 41 can drive the third handling module 42 to move according to the category of the product picked up by the third handling module 42, so that the third handling module 42 can adaptively move to the corresponding placement area 321, thereby placing each product picked up by the third handling module 42 in the corresponding placement area 321.

[0083] Specifically, taking the example that the categories of the four products carried by the third handling module 42 are all different, after the third handling module 42 moves to the classification table 32, the third transfer module 41 can drive the third handling module 42 to move to the four placement areas 321 in sequence. After the third handling module 42 moves to any placement area 321, the third handling member 422 carrying the product corresponding to the placement area 321 descends in the vertical direction, thereby placing the product corresponding to the placement area 321 separately in the loading area.

[0084] Similarly, if there are products of the same category among the four products handled by the third handling module 42, after the third handling module 42 moves to the corresponding placement area 321, the third handling member 422 that handles the products of the same category descends together in the vertical direction, thereby placing the products of the same category together in the placement area 321.

[0085] It is understandable that the first driving member 421 may be a linear driving structure such as a cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0086] In addition, illustratively, the third transfer module 41 is a robot. Of course, in other optional embodiments, the third transfer module 41 can also be a driving structure composed of driving components such as a KK module, and this embodiment does not impose specific limitations on this.

[0087] It is worth noting that, in this embodiment, the code scanning mechanism includes two classification tables 32, and all classification tables 32 are correspondingly provided with a second transfer mechanism 4. The two second transfer mechanisms 4 can both transport products from the code scanning table 35 and place the products on the corresponding classification table 32.

[0088] From the above, on the one hand, this embodiment uses two second transfer mechanisms 4 to classify the scanned products, thereby further improving the working efficiency of the product classification device. On the other hand, for any one of the second transfer mechanisms 4 and the corresponding classification table 32, after the third transfer module 41 drives the third handling module 42 to move to one of the placement areas 321, if the third handling module 42 needs to place more than two similar products in the placement area 321, and the number of the remaining third loading positions 3211 in the placement area 321 is less than the number of similar products that need to be placed, the third handling module 42 places products in the remaining third loading positions 3211 in the placement area 321 to fill the placement area 321 with products. For the products that are not placed in the placement area 321, the second transfer mechanism 4 places them in the placement area 321 corresponding to the type of products on another classification table 32. Afterwards, the third transfer module 41 drives the third handling module 42 to return to the original classification table 32, and places other types of products in the corresponding placement areas 321, and then transfers all the products in the placement areas 321 that are full of products to the down-feeding workstation.

[0089] It is understandable that three or more classification stations 32 may be provided in other optional embodiments, and all classification stations 32 are correspondingly provided with a second transfer mechanism 4. This embodiment does not impose any specific limitation on the number of classification stations 32.

[0090] Furthermore, the product classification device also includes a defective product platform, and the second transfer mechanism 4 can transport defective products to the defective product platform. That is, the product classification device in this embodiment can not only classify good products, but also sort defective products.

[0091] Based on the above-mentioned contents, two second transfer mechanisms 4 are provided in the present embodiment. Accordingly, the product classification device includes two defective material tables, and the two defective material tables correspond to the two second transfer mechanisms 4 one by one.

[0092] Exemplarily, in order to facilitate the staff or a special material receiving mechanism to receive the defective products, and considering the limited travel of the third transfer module 41, in this embodiment, one of the two defective material tables is arranged between the two second transfer mechanisms 4, and the defective material table is the first material table 71, and the other of the two defective material tables is arranged on the side of one of the second transfer mechanisms 4 away from the other second transfer mechanism 4, and the defective material table is the second material table 72, wherein the first material table 71 includes four fourth loading positions 711, and the second material table 72 is configured to place the fourth loading position 711 for loading the second material table 72. The second transfer mechanism 4 away from the second tasting table 72 can place the defective products on the fourth loading position 711, and the second transfer mechanism 4 close to the second tasting table 72 can place the defective products on the pallet placed on the second tasting table 72. It can be understood that after the first tasting table 71 is fully loaded, the second transfer mechanism 4 close to the second tasting table 72 can move all the products on the first tasting table 71 to the pallet placed on the second tasting table 72. After the pallet is fully loaded, the staff or a special material receiving mechanism can replace the pallet.

[0093] In addition, it should be noted that, based on production requirements, the products flowing out of the product classification device need to flow to the downstream processing station in an inverted state. For this reason, in this embodiment, the product classification device also includes a flipping mechanism 8, and the second transfer mechanism 4 can transport the products from the placement area 321 to the flipping mechanism 8 and the unloading station in sequence. The flipping mechanism 8 is configured to flip the products, that is, in this embodiment, the products in the placement area 321 are first transported to the flipping mechanism 8 for flipping, and then transported to the unloading area 512 for unloading.

[0094] Based on the above-mentioned contents, it can be understood that all the second transfer mechanisms 4 are correspondingly provided with a flipping mechanism 8 .

[0095] Exemplarily, in the present embodiment, the flipping mechanism 8 includes a carrier 81, on which a fifth loading position 811 is arranged. It can be understood that the number of the fifth loading positions 811 is consistent with the number of the third loading positions 3211 arranged in the placement area 321, that is, in the present embodiment, four fifth loading positions 811 are arranged on the carrier 81, and the second transfer mechanism 4 can simultaneously carry four products in the placement area 321 and place the four products one by one in the four fifth loading positions 811, and the fifth loading position 811 is provided with an avoidance hole 812. In addition to the carrier 81, the flipping mechanism 8 also includes a mounting plate 82, a flipping clamp 83, a second driving member 84 and a third driving member 85, wherein the carrier 81 is slidably connected to the mounting plate 82 in a direction perpendicular to the arrangement direction of the four fifth loading positions 811, and the number of the flipping clamps 83 is consistent with the number of the fifth loading positions 811, that is, the flipping mechanism 8 includes four The flip clamps 83 correspond one-to-one to the four fifth loading positions 811. The second driving member 84 can drive the carrier 81 to move in a direction perpendicular to the arrangement direction of the four fifth loading positions 811, so that the carrier 81 has a first working position away from the flip clamps 83, and moves to a second working position between the two claws of the flip clamps 83. When the carrier 81 is located at the first working position, the second transfer mechanism 4 can place the four products one by one into the four fifth loading positions 811. Thereafter, the carrier 81 moves from the first working position to the second working position. When the carrier 81 is located at the second working position, the four flip clamps 83 correspond one-to-one to the four fifth loading positions 811, and the two claws of the flip clamps 83 are respectively located on the upper and lower sides of the fifth loading position 811, and are respectively located directly above and directly below the avoidance hole 812, so that the flip clamps 83 can clamp the products.

[0096] The third driving member 85 can drive the mounting plate 82 to rise and fall in the vertical direction. When the platform 81 is located at the second working position and the flipping claw 83 clamps the product, the third driving member 85 drives the mounting plate 82 to descend in the vertical direction, thereby driving the platform 81 to descend in the vertical direction. In addition, since the fifth loading position 811 is provided with an avoidance hole 812, the present embodiment can avoid the flipping claw 83 from interfering with the movement of the platform 81, so that the platform 81 can be moved away from the flipping claw 83 in the vertical direction. After the turning jaw 83 is lowered, it turns over, thereby driving the product to turn over. Then, the carrier 81 rises in the vertical direction until the two claws of the turning jaw 83 are respectively located at the upper and lower sides of the fifth loading position 811 again. Then, the turning jaw 83 releases the grip of the product, and the product is placed again at the fifth loading position 811. Then, the second driving member 84 drives the carrier 81 to return to the first working position. The second turning mechanism 84 takes all the products from the carrier 81 and transfers all the products to the unloading area 512 for unloading.

[0097] It is understandable that the second driving member 84 and the third driving member 85 can be selected as linear driving structures such as cylinders or electric cylinders, and this embodiment does not impose any specific limitation on this.

[0098] In addition, it should be noted that since the inverted products are not suitable for suction, in this embodiment, the second transfer mechanism 4 includes two third handling modules 42, and the two third handling modules 42 are symmetrically arranged. The third handling member 422 of one third handling module 42 is a suction cup, and the third handling member 422 of the other third handling module 42 is a pneumatic clamp. The third transfer module 41 can exchange the positions of the two third handling modules 42, so that there is always a third handling module 42 in a working state. For the third handling module 42 in a working state, the third handling member 422 thereon faces downward, so that it can carry or place products.

[0099] From the above, in this embodiment, when the second transfer mechanism 4 moves the product from the scanning table 35 and places the product on the classification table 32, and moves the product from the classification table 32 and places the product on the carrier 81, the third handling member 422 is the third handling module 42 of the suction cup and is in a working state; when the second transfer mechanism 4 moves the product from the carrier 81 and places the product on the unloading area 512, the third handling member 422 is the third handling module 42 of the pneumatic clamp and is in a working state.

[0100] Of course, in other optional embodiments, the second transfer mechanism 4 may also only have one third handling module 42, and the third handling member 422 of the third handling module 42 may be a suction cup or a pneumatic clamp, etc. This embodiment does not impose any specific limitation on this.

[0101] Furthermore, it should be noted that, in the present embodiment, the unloading mechanism 5 includes two tray conveyors 51, and both tray conveyors 51 are provided with a loading area 511 and two unloading areas 512. The loading area 511 is used to supply empty trays to the two unloading areas 512, and the unloading area 512 can deliver fully loaded trays.

[0102] It is understandable that, since the specific structure and working principle of the tray conveyor 51 are all existing technologies, this embodiment will not elaborate on them.

[0103] In summary, in the present invention, the loading mechanism 1 and the first transfer mechanism 2 supply the products to be classified to the scanning mechanism, the scanning mechanism accurately identifies the category of the product through the scanner 31, and the second transfer mechanism 4 places the scanned products in the corresponding placement area 321 according to the category. After any placement area 321 is full of products, the second transfer mechanism 4 can simultaneously transfer all the products in the placement area 321 to the corresponding unloading area 512 for unloading, thereby realizing automatic classification of products with high work efficiency. Moreover, the product classification device scans the code through the scanner 31 to identify the category of the product, thereby accurately classifying the product.

[0104] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
