Description

Technical Field

[0001] The utility model relates to the technical field of detection and classification, and particularly relates to a ceramic chip detection device. Background Art

[0002] In order to improve the production efficiency of small-sized ceramic chips, generally, a large ceramic chip is produced and divided into more small-sized ceramic chips by means of cutting.

[0003] In order to divide the ceramic chip, the simplest way is cutting. However, cutting will generate a large amount of dust, and to ensure high-precision cutting, more complex positioning and clamping are required.

[0004] Currently, it is generally chosen to set fracture grooves on the large-sized ceramic chip during production, that is, multiple parallel and intersecting fracture grooves are provided on the surface of the large-sized ceramic chip. These fracture grooves pre-divide the large-sized ceramic chip into multiple small-sized ceramic chips, and by applying an external force manually, the ceramic chip can be broken along the fracture grooves, so that the large-sized ceramic chip is split into multiple small-sized ceramic chips. However, the method of manually breaking the chips has low efficiency, and the smaller the size of the ceramic chip, the greater the external force applied to break the chip, which is not conducive to mass production.

[0005] If a specific device is used to automatically fracture the ceramic chip, the production efficiency can be greatly improved. However, the fracture grooves on the ceramic chip are distributed on one side surface of the ceramic chip. In order to ensure the fracture quality and consistency, it is best to keep all ceramic chips in the same posture, for example, the side surface of the ceramic chip with the fracture grooves is placed upward.

[0034] In order to improve the production efficiency of small-sized ceramic sheets, generally, a large ceramic sheet is selected and divided into more small-sized ceramic sheets by means of scribing. For example, when producing a large-sized ceramic sheet, scribing grooves are provided, that is, multiple parallel and intersecting scribing grooves are provided on the surface of the large-sized ceramic sheet, and these scribing grooves pre-divide the large-sized ceramic sheet into multiple small-sized ceramic sheets. As Figure 2 shown in the ceramic sheet 800, multiple scribing grooves are provided on one side surface thereof, including multiple parallel first scribing grooves and multiple parallel second scribing grooves. The first scribing grooves and the second scribing grooves are perpendicular to each other, and the ceramic sheet 800 is pre-divided into multiple small-sized ones from the large size.

[0035] If a specific device is used to automatically split ceramic chips, the production efficiency can be greatly improved. However, the split grooves on the ceramic chips are distributed on one side surface of the ceramic chips. To ensure the split quality and consistency, it is best to make all the ceramic chips in the same posture. For example, the side surface of the ceramic chip with the split groove is placed upward.

[0036] Referring to Figure 1 As shown, the ceramic chip detection device of an embodiment of the present invention includes a conveying device 100, a detection device 200, a first picking device 300, and a first material collecting device 400. The conveying device 100 has a conveying surface for conveying ceramic chips; the detection device 200 is provided with a field of view facing the conveying surface, and the detection device 200 is used to capture images of ceramic chips; the first picking device 300 is erected above the conveying surface, and the first picking device 300 has a first moving direction and a second moving direction, the first moving direction is parallel to the conveying surface, and the second moving direction is perpendicular to the conveying surface; the first material collecting device 400 is arranged on the moving path of the first picking device 300, and the first material collecting device 400 is used to receive the ceramic chips carried by the first picking device 300. The ceramic chip detection device of the present invention can detect and screen out ceramic chips in a preset posture, stack the ceramic chips and keep the same posture.

[0037] The conveying device 100 is used to convey ceramic chips. The ceramic chips can be directly transferred to the conveying surface by a production device through a conveyor belt, or can be manually loaded, or can be picked up and loaded by a manipulator.

[0038] The conveying device 100 is configured to move in a transportation direction from the detection device 200 towards the first picking device 300. That is, when the ceramic chip moves on the conveying surface, it is first detected by the detection device 200 and then moves to the first picking device 300. It should be understood that the first picking device 300 selectively picks up ceramic chips, rather than picking up all ceramic chips, and specifically judges according to the structure feedback by the detection device 200.

[0039] The detection device 200 is used to capture images of ceramic chips. Preferably, when the conveying device 100 transports the ceramic chips to the position of the detection device 200, the conveying device 100 stops working. After the detection device 200 captures the surface image of the ceramic chip, the conveying device 100 continues to transport the ceramic chips.

[0040] One side surface of the ceramic sheet is provided with a splitting groove, and the other side surface is not provided with a splitting groove. Therefore, when the side surface with the splitting groove faces upward, the image captured by the detection device 200 has obvious features, and the attitude of the ceramic sheet can be judged according to this feature. Here, the attitude of the ceramic sheet refers to the orientation of the surface of the ceramic sheet. For example, when the side surface of the ceramic sheet with the splitting groove faces upward, it is the preset attitude, that is, the required attitude. When the detection device 200 detects that the current ceramic sheet is in the preset attitude, it drives the first picking device 300 to pick up the ceramic sheet and place the ceramic sheet at the first material receiving device 400. When multiple ceramic sheets are all placed at the first material receiving device 400, that is, the stacking of the ceramic sheets in the preset attitude is completed.

[0041] It should be understood that when the detection device 200 detects that the current ceramic sheet does not belong to the preset attitude, the first picking device 300 will not act until the ceramic sheet leaves the working range of the first picking device 300.

[0042] It can be understood that a second picking device 500 and a second material receiving device 600 are provided. The second picking device 500 is arranged at an interval from the first picking device 300. The second picking device 500 is erected above the conveying surface. The second picking device 500 has a third moving direction and a fourth moving direction. The third moving direction is parallel to the conveying surface, and the fourth moving direction is perpendicular to the conveying surface. The second material receiving device 600 is arranged on the moving path of the second picking device 500, and the second material receiving device 600 is used to receive the ceramic sheet carried by the second picking device 500.

[0043] In order to improve the material receiving efficiency of the ceramic sheet, the added second picking device 500 and second material receiving device 600 can pick up the ceramic sheets that do not belong to the preset attitude. Since the ceramic sheet has only two side surfaces, and one side surface has a splitting groove, when the splitting groove faces upward, the ceramic sheet is in the preset attitude and needs to be picked up by the first picking device 300. When the splitting groove faces downward, the first picking device 300 will not pick up the ceramic sheet. When this ceramic sheet moves to the second picking device 500, it can be picked up by the second picking device 500 and transferred to the second material receiving device 600. Similarly, the ceramic sheets that do not belong to the preset attitude can also be stacked at the second material receiving device 600 and maintain the same attitude. Finally, only need to turn over the ceramic sheets at the second material receiving device 600 uniformly, and these ceramic sheets can be converted into ceramic sheets in the preset attitude.

[0044] It can be understood that the first picking device 300 is located between the second picking device 500 and the detection device 200. Along the moving direction of the conveying surface, the distance between the first picking device 300 and the second picking device 500 is A, and the distance between the first picking device 300 and the detection device 200 is B, where the distance A is an integer multiple of the distance B.

[0045] In the above structure, controlling the ratio of distance A to distance B is beneficial to reducing the start-stop times of the conveying device 100, shortening the working cycle and improving the efficiency. Specifically, if distance A is the same as distance B, that is, the ratio of distance A to distance B is 1:1, only by controlling the intervals of the ceramic sheets on the conveying surface to be consistent and the interval distance of the ceramic sheets to be a specific value, whenever a ceramic sheet moves to the detection device 200, if there is a ceramic sheet in the preset posture, then it must be at the position of the first picking device 300, and if there is a ceramic sheet in a non-preset posture, then it must be at the position of the second picking device 500. That is to say, when there is a ceramic sheet at the position of the detection device 200, the conveying device 100 stops moving the ceramic sheet, the detection device 200 captures the image of the ceramic sheet, the first picking device 300 can pick up the ceramic sheet in the preset posture synchronously (if there is a ceramic sheet in the preset posture), and the second picking device 500 can pick up the ceramic sheet in the non-preset posture synchronously (if there is a ceramic sheet in the non-preset posture).

[0046] If distance A is twice distance B, that is, the interval between the first picking device 300 and the second picking device 500 is larger and they are farther apart. If there is a ceramic sheet in a non-preset posture, then when the conveying device 100 stops once, the ceramic sheet may stop at the midpoint position between the first picking device 300 and the second picking device 500, and when the conveying device 100 stops next time, the ceramic sheet can stop at the position of the second picking device 500. Among them, every time the ceramic sheet stops, there must be a ceramic sheet at the detection device 200, and the detection device 200 captures the image for posture recognition.

[0047] In the above situation, the intervals of the ceramic sheets on the conveying surface are consistent, and the interval distance of the ceramic sheets is a specific value. This specific value is generally selected to be the same as distance B, that is, the interval distance between the first picking device 300 and the detection device 200 is the placement interval distance of the ceramic sheets. Under this condition, when one ceramic sheet is at the position of the detection device 200, another ceramic sheet will be at the position of the first picking device 300. Of course, the specific value can also be an integer multiple of distance B, and it can be flexibly adjusted according to the production speed of the upstream ceramic sheets.

[0048] Refer to Figure 3As shown, it can be understood that the first picking device 300 includes a first guiding and driving rail 310, a first linear driving assembly 320, and a first adsorption assembly 330. The first guiding and driving rail 310 is installed above the conveying surface, and the first guiding and driving rail 310 extends to the outside of the conveying surface. The first linear driving assembly 320 is slidably connected to the first guiding and driving rail 310, and the moving direction of the first linear driving assembly 320 is perpendicular to the conveying surface. The first adsorption assembly 330 is arranged on the first linear driving assembly 320, and the first linear driving assembly 320 drives the first adsorption assembly 330 to move.

[0049] The first adsorption assembly 330 is arranged on the first linear driving assembly 320. The first linear driving assembly 320 can drive the first adsorption assembly 330 to move towards the conveying surface, so that the first adsorption assembly 330 can contact and adsorb the ceramic sheet on the conveying surface. After the first adsorption assembly 330 picks up the ceramic sheet, the first guiding and driving rail 310 drives the first linear driving assembly 320 to move until the first linear driving assembly 320 moves above the first material receiving device 400. Generally, the first material receiving device 400 is set at the same height as the conveying surface. Therefore, when the first linear driving assembly 320 moves above the first material receiving device 400, the first linear driving assembly 320 then drives the first adsorption assembly 330 to descend to the position of the first material receiving device 400, and places the ceramic sheet on the first material receiving device 400.

[0050] It should be understood that the first adsorption assembly 330 can use a non-contact suction nozzle, that is, the suction nozzle is connected to a high-pressure gas supply device, and a high-speed air flow is blown out from the suction nozzle. Through the Bernoulli principle, a high-speed air flow is generated between the suction nozzle and the ceramic sheet to be adsorbed, so that the ceramic sheet is adsorbed by the suction nozzle. Using a non-contact suction nozzle can have a wide applicability, can adsorb different ceramic sheets, and reduce the work of changing the type of the first adsorption assembly 330.

[0051] Refer to Figure 4 As shown, it can be understood that the first material receiving device 400 includes a second linear driving assembly 410 and a material loading plate 420. The second linear driving assembly 410 has a vertical moving stroke. The material loading plate 420 is connected to the second linear driving assembly 410, and the second linear driving assembly 410 drives the material loading plate 420 to move vertically.

[0052] The material loading plate 420 is used to receive the ceramic sheets transferred by the first adsorption assembly 330, and the ceramic sheets are stacked on the surface of the material loading plate 420. After multiple ceramic sheets are stacked on the material loading plate 420, the vertical distance between the uppermost ceramic sheet and the first adsorption assembly 330 is shortened. In order to prevent the first adsorption assembly 330 from knocking down the stacked ceramic sheets, the moving stroke of the first linear driving assembly 320 can be controlled to be shortened, but in this case, the structure of the first linear driving assembly 320 is more complex.

[0053] A simpler way is to move the material loading plate 420 through the second linear drive assembly 410. The second linear drive assembly 410 has a vertical moving stroke. After a ceramic sheet is placed on the material loading plate 420, the second linear drive assembly 410 can control the material loading plate 420 to move downward by a preset distance, and the downward distance is generally equal to the thickness of the ceramic sheet. In this way, the vertical distance between the uppermost ceramic sheet and the first adsorption assembly 330 remains constant, and there is no need to adjust the first linear drive assembly 320.

[0054] It can be understood that a limiting plate 430 is provided. The limiting plate 430 surrounds the side of the material loading plate 420, and the limiting plate 430 extends along the moving stroke direction of the second linear drive assembly 410. The limiting plate 430 forms a material guiding channel, and the material loading plate 420 moves within the material guiding channel.

[0055] Furthermore, in order to prevent the stacked ceramic sheets from collapsing, the position of the ceramic sheets is restricted by setting the limiting plate 430. Specifically, the limiting plate 430 surrounds the side of the material loading plate 420, such as around the four sides of the material loading plate 420, to form a material guiding channel. The material guiding channel extends along the moving stroke direction of the second linear drive assembly 410, enabling the material loading plate 420 to move within the material guiding channel. The stacked ceramic sheets are restricted by the limiting plate 430 around their four sides and will not shift and collapse laterally. And the ceramic sheets that are slightly shifted and misaligned laterally can also have their positions corrected by being guided by the limiting plate 430 during the downward movement of the material loading plate 420. A chamfer can be synchronously provided at the uppermost end of the limiting plate 430.

[0056] In order to achieve a better limiting effect, the cross-sectional size of the material guiding channel surrounded by the limiting plate 430 can be similar to the size of the ceramic sheet.

[0057] It can be understood that the detection device 200 includes a camera assembly 210 and an image processing component. The camera assembly 210 is mounted above the conveying surface, and the field of view of the camera assembly 210 faces the conveying surface. The camera assembly 210 is electrically connected to the image processing component.

[0058] The camera assembly 210 is used to capture the surface image of the ceramic sheet and send the image to the image processing component for analysis. The image processing component can have an analysis module and a control module, and determine whether the first picking device 300 needs to pick up the ceramic sheet according to the result of the image analysis. Or after a second picking device 500 is provided, determine whether the ceramic sheet should be picked up by the first picking device 300 or the second picking device 500.

[0059] It can be understood that a supplementary light 220 is provided. The supplementary light 220 is used to irradiate the conveying surface, and the irradiation area of the supplementary light 220 covers the field of view of the camera assembly 210.

[0060] In order to enable the camera assembly 210 to obtain a clearer surface image of the ceramic sheet or make the crack grooves in the image more obvious, a supplementary light 220 can be provided to supplement the brightness of the position of the ceramic sheet. It should be understood that preferably a ring-shaped light source is used, and the ring-shaped light source is arranged between the camera assembly 210 and the conveying surface and is closer to the conveying surface to increase the brightness of the surface of the ceramic sheet. The central position of the ring-shaped light source allows the camera assembly 210 to pass through and capture the surface image of the ceramic sheet.

[0061] Referring to Figure 5 As shown, it can be understood that a feeding device 700 is provided, and the feeding device 700 is used to transport the ceramic sheet to be detected to the conveying surface.

[0062] The ceramic sheet can be directly transferred to the conveying surface by the production equipment through a conveyor belt, or it can be manually loaded, or it can be picked up and loaded by equipment. If the production line of the ceramic sheet is not continuous, a feeding device 700 needs to be set. Generally, the ceramic sheets are contained in a material box, and the postures of the ceramic sheets in the material box are not uniform, so a ceramic sheet detection device is required for detection and screening. The material box is placed at the position of the feeding device 700, and the feeding device 700 transports the ceramic sheet to the conveying surface.

[0063] It can be understood that the feeding device 700 includes a rotating assembly 710 and two suction nozzle assemblies 720. The rotating assembly 710 is erected above the conveying surface. The two suction nozzle assemblies 720 are connected to the rotating assembly 710, and the two suction nozzle assemblies 720 are distributed at an interval of 180 degrees around the rotation direction of the rotating assembly 710. The rotation plane of the rotating assembly 710 is parallel to the conveying surface.

[0064] When the suction nozzle assembly 720 at a position far from the conveying surface sucks the ceramic sheet, the suction nozzle assembly 720 located above the conveying surface can synchronously release the ceramic sheet onto the conveying surface. Then the rotating assembly 710 drives the two suction nozzle assemblies 720 to rotate to exchange positions, so that the suction nozzle assembly 720 sucking the ceramic sheet moves to the conveying surface and can release the ceramic sheet, and the other suction nozzle assembly 720 can suck a new ceramic sheet.

[0065] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
