Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to an automatic bottle cap testing and sorting device. Background Technology

[0002] After production, bottle caps (crown caps) need to undergo quality inspection. The inspection usually includes: whether the bottle cap has defects, whether the internal sealing sticker is properly positioned, whether the internal coding is completely applied, and whether the internal QR code can be effectively identified.

[0003] In addition, bottle caps from different brands (because their appearance is almost identical) are often mixed together due to prize confirmation, recycling, and other reasons, and bottle caps from different brands and prizes need to be sorted out later.

[0004] Regardless of the situation, bottle caps need to be inspected and sorted. At present, the inspection equipment has low inspection efficiency, and bottle caps need to be inspected one by one before separation. Some equipment can inspect multiple bottle caps at the same time, but because the location of the problematic bottle caps among multiple bottle caps is uncertain, the subsequent sorting process of OK products (specified bottle caps) and NG products (non-specified bottle caps) is relatively difficult.

[0005] Therefore, it is urgent to provide a high-efficiency bottle cap detection and sorting device. Utility Model Content

[0006] The purpose of this application is to provide an automatic bottle cap detection and sorting device to solve the above-mentioned problems.

[0007] To achieve the above objectives, the technical solution of this application is as follows: An automatic bottle cap detection and sorting device includes: A tray is slidably positioned between the feeding position and the detection position, and the tray is provided with a mounting groove for holding the bottle caps to be tested; The sorting assembly is slidably disposed along the length of the mounting groove; the sorting assembly includes a vacuum nozzle slidably disposed along the vertical direction and a lever slidably disposed along the vertical direction; A detection camera is positioned above the detection position to acquire visual information about the bottle cap.

[0008] Preferably, the bottom of the tray is provided with a support plate, the tray is slidably mounted on the support plate, and the support plate is provided with a first cylinder, the extension end of the first cylinder being connected to the tray.

[0009] Preferably, there are multiple mounting slots, which are arranged along the tray. The number of vacuum nozzles corresponds to the number of mounting slots, and the lever is provided with teeth, the number of which corresponds to the number of mounting slots.

[0010] Preferably, the number of mounting slots is three.

[0011] Preferably, the sorting component is slidably disposed between the pick-up position and the detach position, and the pick-up position is disposed above the detection position; Below the detachment position is a temporary storage box for NG products, and a guide channel is provided between the temporary storage box for NG products and the detection position; The OK products removed by the pick will enter the OK product storage box through the guide channel.

[0012] Preferably, an inclined baffle is provided above the flow channel, with the lower edge of the inclined baffle connected to the edge of the NG product temporary storage box, and the higher edge forming a material passage gap between the baffle and the mounting groove when the product is in the detection position.

[0013] Preferably, the bottom of both ends of the mounting groove is provided with a first sensor and a second sensor for detecting whether the bottle cap is in place.

[0014] Preferably, each of the three vacuum nozzles is independently slidable via a second cylinder; The lever is slidably set via a third cylinder.

[0015] Preferably, it also includes a conveyor belt and a feeding vibratory feeder; One end of the conveyor belt is connected to the outlet of the feed vibratory plate, and the other end of the conveyor belt is connected to the mounting groove located at the feed position.

[0016] The automatic bottle cap detection and sorting device disclosed in this application, by setting up a tray and sorting components, allows the bottle caps to be detected to be arranged sequentially in the mounting slot, so that each bottle cap can obtain a specific position. This ensures that after receiving feedback from the detection camera, the sorting components can accurately pick up a certain bottle cap in the mounting slot and remove the remaining normal bottle caps from the mounting slot, thereby ensuring the accuracy and efficiency of sorting.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0020] like Figure 1-6 As shown, an automatic bottle cap detection and sorting device includes: The tray 1 is slidably positioned between the feeding position 200 and the detection position 100. The tray 1 is provided with a mounting groove 11 for holding the bottle caps to be tested.

[0021] The tray 1 has a plate-like structure and can reciprocate between the feeding position 200 and the detection position 100 under the action of the driving structure.

[0022] The tray 1 is provided with a mounting slot 11, which is used to store the bottle caps to be tested. The mounting slot 11 can effectively limit the position of the bottle caps and prevent the position of the bottle caps from changing during the movement of the tray 1.

[0023] Preferably, the length direction of the mounting groove 11 can be perpendicular to the moving direction of the tray 1, thereby preventing the bottle cap from moving in the mounting groove 11 due to inertia.

[0024] The sorting component 2 is slidably disposed along the length of the mounting groove 11; the sorting component 2 includes a vacuum nozzle 23 slidably disposed along the vertical direction and a lever 25 slidably disposed along the vertical direction.

[0025] The entire sorting component 2 can slide along the length of the mounting groove 11. In practice, the sorting component 2 can slide through the linear motor module 20 to separate NG products from OK products in the detected bottle caps.

[0026] The sorting assembly 2 includes a vacuum nozzle 23 and a lever 25. The vacuum nozzle 23 is used to pick up NG products, while the lever 25 is used to directly push OK products away along the mounting groove 11.

[0027] The detection camera 3 is positioned above the detection position 100 to acquire visual information about the bottle cap.

[0028] After the inspection camera 3 acquires video images of each bottle cap, it compares the images with those of the standard product to determine whether the product is NG or OK. Finally, the PLC program drives the cylinder, solenoid valve, and linear motor module 20 to perform the corresponding actions, thereby achieving the sorting of the products.

[0029] It should be noted that the working principle of identifying NG and OK of products by detecting camera 3 is widely used in industrial production and is existing technology. Its working principle will not be described again in this embodiment.

[0030] The inspection camera 3 can be mounted on the mounting frame 31 constructed from profiles; in addition, a light source 30 is also provided on the mounting frame 31 to illuminate the bottle cap to be inspected, so as to ensure the quality of the acquired image.

[0031] By setting up tray 1 and sorting component 2, the bottle caps to be inspected can be arranged sequentially in mounting slot 11, so that each bottle cap can obtain a specific position. This ensures that after receiving feedback from the detection camera 3, the sorting component 2 can accurately suck up a certain bottle cap in the mounting slot 11 and remove the remaining normal bottle caps from the mounting slot 11, thus ensuring the accuracy and efficiency of sorting.

[0032] In some further embodiments, a support plate 14 is provided at the bottom of the tray 1, the tray 1 is slidably disposed on the support plate 14, and a first cylinder 15 is provided on the support plate 14, the telescopic end of the first cylinder 15 is connected to the tray 1.

[0033] The support plate 14 is set on the workbench 10. The first cylinder 15 can be a single-rod main body cylinder, which occupies less space but has a larger stroke.

[0034] The sliding mechanism between the tray 1 and the support plate 14 can be achieved through a standard linear guide rail module. For example, the slider is set at the bottom of the tray 1, while the corresponding sliding guide rail is set on the upper side of the support plate 14.

[0035] In some further embodiments, there are multiple mounting slots 11, which are arranged along the tray 1; the number of vacuum nozzles 23 corresponds to the number of mounting slots 11, and the lever 25 is provided with teeth 250, the number of teeth 250 corresponding to the number of mounting slots 11.

[0036] The number of mounting slots 11 can be multiple, thereby further improving the detection efficiency, that is, multiple bottle caps can be detected at one time.

[0037] The lever 25 is provided with corresponding teeth 250, and the teeth 250 are set in the mounting slot 11.

[0038] In some further embodiments, the number of mounting slots 11 is three.

[0039] In this embodiment, the number of mounting slots 11 is preferably three.

[0040] Of course, in other embodiments, the number of mounting slots 11 can also be four or five.

[0041] In some further embodiments, the sorting component 2 is slidably disposed between the pick-up position 400 and the disengagement position 300, with the pick-up position 400 disposed above the detection position 100; Below the detachment position 300, there is an NG product temporary storage box 21, and a guide channel 6 is provided between the NG product temporary storage box 21 and the detection position 100; The OK products removed by the pick 250 will enter the OK product storage box 22 through the guide channel 6.

[0042] When the sorting component 2 is at the pickup position 400, the vacuum nozzle can move down to pick up the bottle cap under the drive mechanism, and then rise. If there is only one NG bottle cap in the mounting slot 11, when the vacuum nozzle 23 picks up the NG bottle cap and moves to the release position 300, the lever 25 will drive the tooth 250 to fall down at the same time and completely remove the remaining OK bottle caps as the sorting component 2 moves to the release position 300. If there are two or more NG bottle caps in the mounting slot 11, the vacuum nozzle 23 will move along the pickup position 400 and the release position 300 several times before the lever 25 falls down to remove all the OK bottle caps.

[0043] Below the detachment position 300, there is an NG product storage box 21 for storing NG bottle caps that have fallen off the vacuum nozzle 23.

[0044] The guide channel 6 is inclined so that the OK bottle caps removed from the mounting slot 11 by the pick teeth 250 will enter the guide channel 6 and slide into the OK product storage box 22, thereby achieving sorting.

[0045] In some further embodiments, an inclined baffle 5 is provided above the flow channel 6, with the lower edge of the inclined baffle 5 connected to the edge of the NG temporary storage box 21, and the higher edge forming a material passage gap 50 between it and the mounting groove 11 when it is located at the detection position 100.

[0046] The inclined baffle 5 has two functions: first, when the NG bottle cap on the vacuum nozzle 23 falls off during the movement, it can touch the upper side of the inclined baffle 5 and slide into the NG temporary storage box 21; second, the OK bottle cap that is knocked off by the pick tooth 250 can be stopped by the lower side wall of the inclined baffle 5 so that it can smoothly enter the guide channel 6.

[0047] OK bottle caps enter the guide channel 6 through the material passage gap 50.

[0048] In some further embodiments, the bottom of the mounting groove 11 at both ends is provided with a first sensor 12 and a second sensor 13 for detecting whether the bottle cap is in place.

[0049] The first sensor 12 and the second sensor 13 can be reflective photoelectric sensors.

[0050] As the bottle caps are conveyed from the front end, they are pushed one by one into the mounting slots 11 in the tray 1. When the first sensor 12 and the second sensor 13 simultaneously detect the presence of the bottle caps, the tray 1 will slide from the feeding position 200 to the detection position 100 under the action of the first cylinder 15.

[0051] In some further embodiments, the three vacuum nozzles 23 are each independently slidable via a second cylinder 24; the lever 25 is slidable via a third cylinder 26.

[0052] The three vacuum nozzles 23 move up and down independently to ensure that NG bottle caps in different positions in different mounting slots 11 are accurately picked up.

[0053] In some further embodiments, a conveyor belt 4 and a feeding vibratory feeder 7 are also included; one end of the conveyor belt 4 is connected to the outlet of the feeding vibratory feeder 7, and the other end of the conveyor belt 4 is connected to the mounting groove 11 located at the feeding position 200.

[0054] The conveyor belt 4 and the feeding vibratory plate 7 are both set on the workbench 10.

[0055] The vibratory feeder transports all the bottle caps to be tested out in a specific posture, and then the bottle caps in a certain posture enter the conveyor belt 4, and then enter the mounting groove 11 located at the feed position 200.

[0056] It should be noted that the motion sequence of the moving parts in the entire device is executed in an orderly manner through the PLC program.

[0057] It should be emphasized that the words "OK" and "NG" appearing above do not only refer to whether the bottle cap is qualified or unqualified, but can also be used to indicate other meanings. For example, "OK" can also be used to indicate that the bottle cap is a specially designated bottle cap, while "NG" indicates that it is not a specially designated bottle cap. For example, "OK" means a bottle cap of a certain brand with a prize of 1 yuan, while "NG" means a bottle cap that is not "the above brand with a prize of 1 yuan" among all the bottle caps to be tested.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
