Detailed implementation manners

[0027] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0028] Refer to Figure 1 and Figure 2 As shown, the present utility model discloses a product detection device, including a first transmission unit 10, an image acquisition unit 20, a material removal unit 30 and a control unit. Preferably, the product in the embodiment is a combination of a needle and its packaging.

[0029] Specifically, the first transmission unit 10 includes a first transmission member 11, a first acquisition member 12, and a second acquisition member 13. The first transmission member 11 is used to transmit products; those skilled in the art can set the specific first transmission member 11 according to actual needs, such as a synchronous belt 112, etc. The first acquisition member 12 is used to obtain the transmission parameter information of the first transmission member 11; those skilled in the art can set the specific transmission parameter information according to actual needs, such as the transmission speed of the synchronous belt 112. In some embodiments where the synchronous belt 112 is driven by a driving pulley 111, the transmission parameter information is set as the angular displacement of the driving pulley 111. The second acquisition member 13 is used to obtain the position information of the product. Here, the products include qualified products and unqualified products, and the position information here is the position of the corresponding product on the first transmission member 11. In actual use, the size of the first transmission member 11 is fixed. When the real-time transmission parameter information and position information are obtained, the time required for the product to move to a certain fixed position, such as the rejection unit 30, can be obtained, thereby realizing accurate rejection.

[0030] The image acquisition unit 20 is used to acquire and analyze the images of the products to obtain unqualified product information. Those skilled in the art can set the corresponding image acquisition unit 20 according to the unqualified product information to be detected, which will not be elaborated here. Preferably, the second acquisition member 13 is arranged close to the image acquisition unit 20 to facilitate more accurate acquisition of the corresponding position information. How to analyze the product images to determine whether they are qualified or unqualified products belongs to the prior art and will not be elaborated here.

[0031] The rejection unit 30 is used to receive the rejection signal and reject unqualified products; those skilled in the art can set the specific rejection unit 30 according to actual needs, such as setting it as a combination of a cylinder and a push block, etc.

[0032] The control unit is electrically connected to the first transmission unit 10, the image acquisition unit 20, and the rejection unit 30 respectively. The control unit is used to receive the unqualified product information and transmit the rejection signal based on the transmission parameter information and the position information of the corresponding unqualified product. The control unit is not shown in the figure; by setting the control unit, it can cooperate with the other units to achieve accurate and efficient rejection.

[0033] During actual use, the products that have completed packaging are successively transported onto the first transmission member 11, and the products move along with the first transmission member 11; the first acquisition member 12 acquires the transmission parameter information of the first transmission member 11 in real time. When the product flows through the image acquisition unit 20, the image acquisition unit 20 acquires the image of the product and analyzes it to determine whether the product is a good product or a defective product. At the same time, the second acquisition member 13 acquires the product position information. When the product is a defective product, the control unit can judge the time required for the product to move to the rejection unit 30 according to the corresponding transmission parameter information and position information, and emit a rejection signal at an appropriate time, so that the rejection unit 30 that receives the rejection signal can accurately reject the defective product from the first transmission member 11.

[0034] For the product detection device described in the present utility model, by setting the first transmission unit 10, the image acquisition unit 20, the rejection unit 30 and the control unit, when detecting products, each unit can cooperate with each other. On the premise of ensuring that the first transmission member 11 can maintain high-speed transmission, it can avoid the occurrence of phenomena such as mis-rejecting good products and missing defective products caused by problems such as inconsistent intervals between adjacent products. It effectively ensures the requirements for high production efficiency and rejection accuracy, guarantees the yield of good products out of the production line, and is very reliable.

A synchronous belt 112 is provided on the driving wheel 111 and the driven wheel, and the driving wheel 111 is in transmission connection with the driving motor 113. The first acquisition member 12 is set as an encoder, and the encoder is connected to the driving wheel 111. The encoder belongs to the prior art, and its specific working principle will not be elaborated here. By setting the first acquisition member 12 as an encoder connected to the driving wheel 111, the corresponding angular displacement information can be effectively acquired, so as to cooperate with the rest of the units and components to achieve precise rejection of defective products, effectively ensuring a high yield of good products.

[0036] Refer to Figure 2 and Figure 4As shown, in some embodiments of the product detection device of the present utility model, the image acquisition unit 20 includes a first image acquisition component 201 and a second image acquisition component 202 to meet the various defect detection requirements for needle-like products. The first image acquisition component 201 and the second image acquisition component 202 are arranged in sequence along the transmission direction of the first transmission member 11. When a defect is detected in the product by one of the groups of components, the product is a defective product. Preferably, the first image acquisition component 201 is used to detect whether there is a missing needle in each product package; the second image acquisition component 202 is used to detect whether the needle model and the packaging color in each product correspond, and whether there are impurities in the package. Both the first image acquisition component 201 and the second image acquisition component 202 include an image acquisition member 21 and a light source member 22 to perform corresponding image acquisition.

[0037] Furthermore, in some embodiments of the product detection device of the present utility model, the synchronous belt 112 is provided with a transparent structure to facilitate the loading of products and the penetration of X-rays; those skilled in the art can set the specific material of the synchronous belt 112 according to actual needs, which will not be elaborated here. The synchronous belt 112 has a bearing surface 1121 for loading products. The image acquisition member 21 and the light source member 22 are respectively arranged on both sides of the bearing surface 1121 in the normal direction to facilitate obtaining clear images, so as to accurately detect whether there are defects in the products. The light source member 22 is used to emit X-rays to the products on the bearing surface 1121, and the image acquisition member 21 is used to collect and analyze the images of the products irradiated by X-rays to obtain defective product information. Needle-like products are small in size and encapsulated in bubbles, and are easily affected by packaging occlusion, which affects detection. By setting X-ray detection, the internal situation can be detected through the packaging. Compared with other detection methods, it is more efficient and accurate.

[0038] Furthermore, referring to Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments of the product detection device of the present utility model, the image acquisition unit 20 further includes a partition board 23 and a partition box body 24. The partition board 23 is arranged between the first image acquisition component 201 and the second image acquisition component 202. By setting this structure, the interference between the two groups of components can be effectively avoided to achieve efficient and accurate detection. The partition board 23 is provided with an avoidance hole for avoiding the first transmission member 11 to facilitate the passage of products. The partition board 23, the first image acquisition component 201 and the second image acquisition component 202 are all arranged inside the partition box body 24. By setting the partition box body 24, the possibility of staff being affected by X-rays can be effectively reduced, which is safe and reliable.

[0039] Referring to Figure 5As shown in the figure, in some embodiments of the product detection device of the present utility model, the material rejection unit 30 includes a nozzle 31 and a gas supply component. The nozzle 31 is provided on one side of the first transmission member 11 perpendicular to its own transmission direction; preferably, it is provided on the horizontal side of the first transmission member 11. The nozzle 31 is communicated with the gas supply port of the gas supply component, and the gas supply component is electrically connected to the control unit. The gas supply component is used to receive the material rejection signal and output gas to reject defective products. The needle-like products are small and light. By setting the material rejection unit 30 with this structure, the response speed is fast, and the rejection of defective products can be effectively realized.

[0040] Further, referring to Figure 5 As shown in the figure, in some embodiments of the product detection device of the present utility model, the material rejection unit 30 further includes a recovery component to facilitate the recovery of defective products for corresponding processing, effectively reducing production costs. Specifically, the recovery component includes a recovery member 321 and a storage member 322. The recovery member 321 is provided on one side of the first transmission member 11 perpendicular to its own transmission direction, and the recovery member 321 is disposed opposite to the nozzle 31. A recovery channel 3211 is formed in the recovery member 321, and the recovery channel 3211 communicates with the first transmission member 11 and the storage member 322 respectively. In actual use, the nozzle 31 ejects gas to blow the defective products into the recovery channel 3211. The defective products move along the recovery channel 3211 and enter the storage member. After reaching a certain quantity, they are uniformly recovered and processed.

[0041] Referring to Figure 6 and Figure 7 As shown in the figure, in some embodiments of the product detection device of the present utility model, it further includes a second transmission unit 40 for blanking buffering. The second transmission unit 40 includes a second transmission member 41 and a third acquisition member. The feeding end of the second transmission member 41 is communicated with the discharging end of the first transmission member 11, and the second transmission member 41 is used to transmit qualified products; those skilled in the art can set the corresponding second transmission member 41 according to actual needs to realize the transmission of the remaining qualified products, which will not be elaborated here. The third acquisition member is used to obtain the position information of the qualified products; preferably, the third acquisition member is set as a laser sensor. The position information of the qualified products here is the position of the qualified products on the second transmission member 41. The control unit is also electrically connected to the second transmission unit 40. The control unit is used to receive the position information of the corresponding qualified products and adjust the transmission speed of the second transmission member 41. When needle-like products are blanked, multiple groups are often blanked at one time to improve the blanking efficiency. At the same time, the size of the second transmission member 41 is fixed, and the products detected in the same batch have the same size. After obtaining the position of the first qualified product on the second transmission member 41, it can be estimated how many more qualified products the second transmission member 41 can accommodate. Therefore, by setting this structure, it is possible to easily adjust the transmission speed of the second transmission member 41 according to actual needs to control the blanking quantity of the products and prevent excessive products from stacking and falling off the second transmission member 41.

[0042] Preferably, referring to Figure 7 As shown, the third collecting member includes a first in-place sensor 421 and a second in-place sensor 422. The first in-place sensor 421 and the second in-place sensor 422 are arranged in sequence along the transmission direction of the second transmission member 41. The first in-place sensor 421 is configured to emit a first in-place signal after a good product arrives, and the second in-place sensor 422 is configured to emit a second in-place signal after a good product arrives. The control unit is configured to reduce the transmission speed of the second transmission member 41 when receiving the first in-place signal, and stop the second transmission member 41 when receiving the second in-place signal. By setting this two-stage in-place detection structure, the control of the product discharging amount can be effectively achieved, preventing excessive product stacking and detachment from the second transmission member 41. Preferably, during the discharging process, the feeding device on the side of the feeding section of the first transmission member 11 synchronously controls the feeding of the product to avoid excessive product transportation on the first transmission member 11, causing unnecessary product stacking. The stop of the second transmission member 41 indicates that the second transmission member 41 is full of good products, and at this time, the corresponding discharging device or the staff performs discharging.

[0043] Preferably, a baffle 411 extending along the transmission direction is provided on the second transmission member 41 to prevent the good product from accidentally detaching from the second transmission member 41. Preferably, the baffle 411 is provided with a blocking portion 412 at a section of the second transmission member 41 away from the first transmission member 11 to block the good product and prevent it from detaching from the second transmission member 41.

[0044] Referring to Figure 1 As shown, in some embodiments of the product detection device of the present invention, the first transmission unit 10 further includes a cleaning member 14. The cleaning member 14 is arranged at the feeding end of the first transmission member 11, and the cleaning member 14 is used to clean the product entering the first transmission member 11. By setting the cleaning member 14, the fed product can be cleaned to avoid the influence of impurities on the product packaging on the detection result, and efficient and accurate detection can be achieved. Those skilled in the art can set the specific cleaning member 14 according to actual needs. Preferably, it is set as a blowing type cleaning.

[0045] Working principle:

[0046] The feeding device transports the product onto the first conveyor 11 and cleans the product through the cleaning member 14. Subsequently, the product moves with the first conveyor 11, and the first acquisition member 12 acquires the transmission parameter information of the first conveyor 11 in real time. When passing through the first image acquisition assembly 201 and the second image acquisition assembly 202, the corresponding image acquisition member 21 and the light source member 22 cooperate to detect defects of the product to determine whether the product is a good product or a defective product. At the same time, the second acquisition member 13 acquires the product position information. When the product is a defective product, the control unit can judge the time required for the product to move to the rejection unit 30 according to the corresponding transmission parameter information and position information, and emit a rejection signal at an appropriate time, so that the rejection unit 30 receiving the rejection signal can accurately reject the defective product from the first conveyor 11.

[0047] The non-rejected good products sequentially enter the second conveyor 41 to achieve buffering before discharging. Each good product moves with the second conveyor 41 to facilitate buffering and accommodating subsequent good products. When the first in-place sensor 421 detects a good product, it emits a first in-place signal to cause the control unit to reduce the transmission speed of the second conveyor 41. When the second in-place sensor 422 detects a good product, it emits a second in-place signal to stop the second conveyor 41. After the second conveyor 41 stops, the operator takes away the good products buffered on the second conveyor 41 and transports them to subsequent workstations.

[0048] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
