Description

Technical Field

[0001] The utility model relates to the field of bamboo product processing equipment, in particular to a detection device for strip products. Background Art

[0002] During the production process of strip products such as chopsticks, due to their slender structure, in order to transport them smoothly, the strip products are usually placed horizontally on a conveying device. Existing conveying devices for strip products, such as the conveying device described in the patent document of Chinese Patent Application No. 201920837686.8, generally include a conveyor belt with a groove on it. During transportation, the strip products correspond one-to-one to the groove on the conveyor belt, and are horizontally limited in the groove on the conveyor belt, and are transported by the conveyor belt. Since the strip products are limited in the groove on the conveyor belt, part of the structure of the strip products will be blocked, making it unsuitable for processes that require observation of the appearance of the blocked parts of the strip products. Utility Model Content

[0007] A product horizontal moving mechanism is provided on the frame between the two groups of cameras;

[0008] The product horizontal pushing mechanism is located at either end of the strip product placement slot, and is used to push the strip product in the strip product placement slot to move horizontally a distance away from one end of the product horizontal pushing mechanism.

[0009] The strip product detection device of the utility model shifts the strip product through the product horizontal pushing mechanism, and has a simple structural design and is easy to operate. In addition, a group of cameras are respectively arranged in front of and behind the conveying of the product horizontal pushing mechanism, so that different parts of the strip product can be exposed when passing through the two groups of cameras, and different parts of the strip product on the conveying mechanism are photographed in batches, so that more surface image data of the strip product can be obtained in the end, and the surface image data of the strip product is more complete and complete, and the accuracy of grading or distinguishing different colors is also higher.

[0010] Furthermore, the product horizontal pushing mechanism is a guide plate, and the side of the guide plate facing the strip product has a guide slope, which is arranged along the conveying direction of the conveying mechanism and inclined toward the strip product side. During operation, the guide slope guides the strip product, so that the strip product is pushed to move horizontally a distance away from one end of the product horizontal pushing mechanism. In addition, the product horizontal pushing mechanism has a simple structure and low cost.

[0011] Furthermore, the conveying mechanism includes two conveyor belts arranged in parallel and spaced apart, the two groups of cameras are located between the two conveyor belts, and a plurality of partitions are arranged in sequence and spaced apart along the conveying direction on each conveyor belt, the partitions on the two conveyor belts are arranged one by one, and the two partitions corresponding to each other form a pair of partitions, and the strip product placement slot is formed between the two adjacent pairs of partitions. When working, each strip product is placed in the strip product placement slot between the two adjacent pairs of partitions, and the product horizontal pushing mechanism pushes the strip product to move it, so that the part of the structure of the strip product originally blocked by the conveyor belt is exposed and exposed in the shooting field of the other group of cameras, so that the appearance of the part blocked by the conveyor belt can be shot and observed.

[0012] Furthermore, the frame is also equipped with a product push and reset mechanism, wherein one group of the cameras, the product horizontal push mechanism, another group of the cameras, and the product push and reset mechanism are sequentially arranged along the conveying direction of the conveying mechanism; the product push and reset mechanism is located at the end of the strip product placement slot away from the product horizontal push mechanism, and is used to push the strip product on the conveying mechanism to move horizontally toward the end close to the product push and reset mechanism, so as to achieve the reset of the strip product. Furthermore, the product push and reset mechanism is a guide plate, and the side of the guide plate facing the strip product has another guide slope, and the other guide slope is arranged along the conveying direction of the conveying mechanism and inclined toward the strip product placement slot.

[0018] The following is a detailed description of the preferred implementation of the strip product detection device of the utility model in conjunction with the accompanying drawings:

[0019] Combination Figure 1 and Figure 2 , a strip product detection device, comprising a frame 10 and at least two sets of cameras (20, 30) fixedly connected to the frame 10;

[0020] A conveying mechanism 40 is installed on the frame 10. A plurality of strip product placement slots 50 are sequentially arranged on the conveying mechanism 40 along its conveying direction. The length of the strip product placement slots 50 is less than the length of the strip product 100.

[0021] The two groups of cameras (20, 30) are arranged in sequence and at intervals along the conveying direction of the conveying mechanism 40, and are used to obtain surface image data of the strip product 100;

[0022] A product horizontal moving mechanism 60 is provided on the frame 10 between the two groups of cameras (20, 30);

[0023] The product horizontal pushing mechanism 60 is located at either end of the strip product placement slot 50 , and is used to push the strip product 100 located on the conveying mechanism 40 to move horizontally a distance away from the end of the product horizontal pushing mechanism 60 .

[0024] During operation, the strip products 100 are placed one by one in each strip product placement slot 50 of the conveying mechanism 40. Since the length of the strip product placement slot 50 is less than the length of the strip product 100, when the two ends of each strip product 100 are aligned, the end of the strip product 100 close to the product horizontal pushing mechanism 60 can extend out of the strip product placement slot 50; the strip products 100 are conveyed forward by the conveying mechanism 40; when conveying through a group of the cameras 20, the group of cameras 20 takes pictures of the strip products 100 on the conveying mechanism 40; thereafter, the strip products 100 are conveyed through the product horizontal pushing mechanism 60, and the strip products 100 are shifted by the pushing action of the product horizontal pushing mechanism 60 on the strip products 100; the displaced strip products 100 are photographed by the other group of cameras 20 when conveying through the other group of cameras 20.

[0025] The strip product detection device of the utility model shifts the strip product 100 through the product horizontal pushing mechanism 60, and has a simple structural design and is easy to operate. In addition, a group of cameras (20, 30) are respectively arranged in front of and behind the conveying of the product horizontal pushing mechanism 60, so that different parts of the strip product 100 can be exposed when passing through the two groups of cameras (20, 30), and different parts of the strip product 100 on the conveying mechanism 40 are photographed in batches, so that more surface image data of the strip product 100 can be finally obtained, and the surface image data of the strip product 100 is more complete and complete, and the accuracy of grading or distinguishing different colors is also higher.

[0026] Further, such as Figure 1 As shown, the product horizontal pushing mechanism 60 is a guide plate, and the side of the guide plate facing the strip product 100 has a guide slope 61, and the guide slope 61 is arranged along the conveying direction of the conveying mechanism and is inclined toward the strip product 100. When working, the guide slope 61 guides the strip product 100, so as to push the strip product 100 to move horizontally for a distance away from one end of the product horizontal pushing mechanism 60. In addition, the product horizontal pushing mechanism 60 has a simple structure and low cost. Of course, the product horizontal pushing mechanism 60 can also adopt existing common horizontal pushing mechanisms such as push rod mechanisms and cylinders.

[0027] Further, combined with Figure 1 and Figure 2The conveying mechanism 40 includes two conveyor belts arranged in parallel and spaced apart. The two groups of cameras (20, 30) are located between the two conveyor belts. A plurality of partitions 70 are arranged in sequence and spaced apart along the conveying direction on each conveyor belt. The partitions 70 on the two conveyor belts are arranged one by one. The two partitions 70 corresponding to each other form a pair of partitions. The strip product placement slots 50 are formed between two adjacent pairs of partitions 70. When working, each strip product 100 is placed in the strip product placement slots 50 between two adjacent pairs of partitions 70. The product horizontal pushing mechanism 60 pushes the strip product 100 to move, so that the partial structure of the strip product 100 originally blocked by the conveyor belt is exposed and exposed in the shooting field of the other group of cameras 30, so that the appearance of the blocked part of the conveyor belt can be shot and observed.

[0028] Further, such as Figure 1 As shown, the frame 10 is also equipped with a product push and reset mechanism 80, wherein one group of the cameras 20, the product horizontal push mechanism 60, and another group of the cameras 30, the product push and reset mechanism 80 are sequentially arranged along the conveying direction; the product push and reset mechanism 80 is located at the end of the strip product placement slot 50 away from the product horizontal push mechanism 60, and is used to push the strip product 100 located in the strip product placement slot 50 to move horizontally toward the end close to the product push and reset mechanism 60, so as to reset the strip product 100. Furthermore, as Figure 1 As shown, the product push and reset mechanism 80 is a guide plate, and the side of the guide plate facing the strip product 100 has another guide slope 81, and the other guide slope 81 is arranged along the conveying direction of the conveying mechanism 40 and is inclined toward the strip product placement slot 50. Of course, the product push and reset mechanism 80 may not be arranged on the frame 10, and the product push and reset mechanism 80 may be arranged or not arranged according to production and actual needs. In addition, the product push and reset mechanism 80 may also adopt an existing common horizontal push mechanism such as a push rod mechanism and a cylinder.

[0029] Further, such as Figure 2 As shown, one group of the cameras 20 includes three cameras 21, and the three cameras 21 are respectively located on the upper and lower sides of the conveying path of the strip product 100 on the conveying mechanism 40, and the installation angle of two or more cameras 21 is limited to the circumferential 360-degree surface image data of the strip product 100 can be obtained by all cameras 21 in the same group. Figure 2As shown, another group of cameras 30 includes three cameras 31, and the three cameras 31 are respectively located on the upper and lower sides of the conveying path of the strip product 100 on the conveying mechanism 40, and the installation angles of the three cameras 31 are limited to that all cameras 31 in the same group can obtain 360-degree circumferential surface image data of the strip product 100. Preferably, as Figure 2 As shown, the cameras of each group of cameras are evenly distributed along the circumference of the strip product 100 on the conveying mechanism 40. At this time, among the three cameras in the same group, the installation angles of the two cameras differ by 120 degrees. During operation, the three cameras take pictures of the outer circumference of the strip product due to three different angles. Under this setting, it is achieved that the complete image data of the circumferential surface of the strip product of 180° is obtained through a small number of cameras. Of course, the number of cameras in each group of cameras (20, 30) is preferably but not limited to three in the drawings, and it can also be one, or two, or more than three.

[0030] Further, such as Figure 2 As shown, the installation angles of the cameras (21, 31) of the two groups of cameras (20, 30) are different, which further increases the surface image data of the strip product 100, and the surface image data of the strip product 100 is more complete and intact. Of course, the cameras (21, 31) of the two groups of cameras (20, 30) can also be kept consistent with each other, but the integrity of the surface image data of the strip product 100 will be slightly deviated.

[0031] For ordinary technicians in the technical field to which the utility model belongs, the utility model can make several simple deductions or substitutions without departing from the concept of the utility model, which should be regarded as falling within the protection scope of the utility model.
