Description

Technical Field

[0001] This utility model relates to the field of visual inspection device technology, and in particular to a visual inspection device for pot dot noodles. Background Technology

[0002] The dome switch visual inspection device is an automated inspection equipment based on machine vision technology, specifically used to inspect the appearance quality, dimensional accuracy, and surface defects of dome switches (a common electronic component, usually used in push-button switches).

[0003] A search revealed that patent CN219434661U proposes an automatic visual inspection device for hot pot dot slices. This technical solution has the following problems:

[0004] The existing method is that after visual inspection of pot dome pieces, the inspection results will include qualified and unqualified products. It is also inconvenient to classify qualified and unqualified pot dome pieces during the transportation process, and they cannot be stored separately, which is not conducive to the handling and utilization of pot dome pieces.

[0005] To address the aforementioned problems, this utility model document proposes a visual inspection device for pot-shaped rice noodles. Utility Model Content

[0006] This utility model provides a visual inspection device for pot dome slices, which solves the problem that in the prior art, the inspection results of pot dome slices after visual inspection include qualified and unqualified products, and it is not convenient to classify qualified and unqualified pot dome slices during the transportation process, nor can they be stored separately, which is not conducive to the handling and utilization of pot dome slices.

[0007] This utility model provides the following technical solution:

[0008] A visual inspection device for dome tiles includes:

[0009] Two support frames are connected to each other by a rotating shaft, and a drive roller and a driven roller are respectively rotatably connected between the two support frames. The outer walls of the drive roller and the driven roller are fitted with the same conveyor belt. A first motor is fixedly installed on one side of one of the support frames. The output end of the first motor is fixed to one end of the drive roller through a coupling.

[0010] The sorting mechanism, mounted on a support frame, is used to classify qualified and unqualified products of the hot pot dot film.

[0011] The feeding mechanism, mounted on a support frame, is used to automatically feed the metal dome pieces to be tested.

[0012] In one possible design, the sorting mechanism includes a mounting block, a second motor, a reciprocating lead screw, a fixing plate, and a limiting rod. The mounting block and the fixing plate are respectively fixedly mounted on the top side of two support frames. The second motor is fixedly mounted on the top of the mounting block. The output end of the second motor is fixedly connected to one end of the reciprocating lead screw via a coupling. The end of the reciprocating lead screw away from the second motor is rotatably connected to one side of the fixing plate via a rotating shaft.

[0013] In one possible design, the outer wall of the reciprocating lead screw is fitted with a correction block that cooperates with the spiral groove of the reciprocating lead screw. The correction block is used to drive and classify qualified and unqualified dome switches. Both limiting rods are fixedly set between the mounting block and the fixing plate. The correction block has two limiting holes inside for limiting the sliding of the limiting rods. Limiting strips are fixedly set on the top sides of both support frames to guide and limit the dome switches during correction.

[0014] In one possible design, a receiving frame is provided on one side of the conveyor belt. The receiving frame has two placement slots inside, which are respectively provided with a qualified product frame and a non-qualified product frame for collecting and storing qualified and non-qualified products of the pot dome chips. Insert blocks are fixedly provided on both sides of the receiving frame. A slot for inserting the insert blocks is provided on one side of the two support blocks. A locking screw is passed through the top side of each support frame. A screw hole for threaded connection of the locking screw is provided on the top side of the insert block.

[0015] In one possible design, the feeding mechanism includes a support block, a mounting frame, an electric push rod, a pushing frame, a placement frame, a placement cavity, a chute, and a baffle. The support block is fixedly mounted on one side of two support frames, the mounting frame is fixedly mounted on the top side of the support block, the placement frame is fixedly mounted on the top side of the mounting frame, and both placement cavities are opened on the top side of the mounting frame for storing and placing the metal dome pieces to be visually inspected.

[0016] In one possible design, two chutes are formed on both sides of the placement frame, and each baffle is slidably connected inside the chutes for controlling the release of multiple stored metal dome pieces. The electric push rod is fixedly installed on the inner wall of one side of the mounting frame, and the push frame is fixedly set at the output end of the electric push rod for pushing and feeding the released metal dome pieces.

[0017] In one possible design, the same automatic visual inspection instrument is fixedly installed on the top side of the two support frames for visual inspection of the hot plate, and the automatic visual inspection instrument is located between the feeding mechanism and the sorting mechanism.

[0018] In this application, during use, the metal dome to be tested is first placed in the placement cavity at the top of the mounting frame. The placement cavity is designed to store a certain number of metal domes for continuous testing. Since there are two placement cavities, the metal domes in the placement cavities can be released in a controlled manner. The sides of the placement frame are provided with sliding grooves, and a baffle is slidably connected in each sliding groove. The baffle is used to control the number of metal domes released. When one of the baffles is open, the metal domes in one of the placement cavities will fall automatically. The gap between the bottom side of the placement frame and the top side of the mounting frame can only accommodate one metal dome, so as to ensure that only one metal dome can be pushed each time. When the test starts, the electric push rod is activated, and the push frame connected to its output end moves forward, pushing the metal dome released at the bottom of the placement frame. This makes it easy for the conveyor belt to catch it and start moving towards the test area, achieving the effect of automatic feeding and improving applicability.

[0019] When the dome switch moves along the conveyor belt to the area below the automatic vision inspection instrument, the instrument is activated. Utilizing advanced visual recognition technology, the instrument performs a comprehensive inspection of the dome switch, including dimensions, shape, and surface defects. After inspection, the automatic vision inspection instrument determines whether the dome switch is a qualified or unqualified product based on preset standards. When the dome switch is qualified, the correction mechanism does not need to operate; it simply waits for the dome switch to be conveyed into the qualified product frame. When the dome switch is unqualified, the correction mechanism receives a signal from the automatic vision inspection instrument, and the second motor starts, driving the reciprocating lead screw to rotate. The correction block works in conjunction with the helical groove of the reciprocating lead screw, moving left and right as the lead screw rotates. The right-moving correction block is designed to push the metal dome pieces to both sides based on the test results, so as to change the collection path for unqualified metal dome pieces. Then, a receiving frame is set at the end of the conveyor belt, with two placement slots inside, one for qualified products and one for unqualified products. This allows qualified and unqualified products to be collected into different frames, which is convenient for subsequent processing and achieves the purpose of classified storage. This is beneficial for the later retrieval and utilization of metal dome pieces and improves the application effect. The receiving frame is fixed to the support frame by inserts and slots, and the locking screws ensure its stability. This not only enhances the installation firmness, but also makes it easy to disassemble and improves the convenience of use.

[0020] The working principle of an automated visual inspection instrument is as follows: The instrument uses a high-precision optical imaging system, such as a lens, to project the image of the hot dome onto an image sensor. The lens's focal length, aperture, and other parameters directly affect the image quality. To ensure clear images and distinct features, the instrument is equipped with a suitable illumination system. This system provides stable and uniform illumination, allowing the hot dome image to present the best visual effect during acquisition. Common illumination methods include ring lights and backlights. The choice of light source type and illumination method depends on the material, shape, and inspection requirements of the hot dome. The acquired hot dome image is converted by an image sensor (such as a CCD or CMOS sensor). The image sensor converts the light signal into an electrical or digital signal, which is then transmitted to an image processing unit for processing. The performance of the image sensor determines the image quality. The image processing unit, which includes hardware and software components, controls key parameters such as resolution and sensitivity. The hardware, such as a digital signal processor, receives and initially processes image signals. The software utilizes various image processing algorithms to perform filtering, enhancement, and edge detection to extract the feature information of the hot plate. In the processed image, the feature information of the hot plate (such as size, shape, color, and texture) is extracted. This feature information is used for subsequent comparison and analysis. The extracted feature information is compared with a preset standard or template. The comparison process may involve various algorithms and mathematical models to ensure the accuracy and reliability of the detection. If the feature information of the hot plate does not match the preset standard, it will be judged as a defective product. Based on the comparison results, the automatic vision inspection instrument will output the detection results, which will include information such as the classification of qualified and unqualified products and the specific defect type of the unqualified product.

[0021] In this utility model, the visual inspection device for pot-shaped noodles, through a classification mechanism, can push the pot-shaped noodles to both sides according to the inspection results, so as to change the collection path for unqualified pot-shaped noodles. It can collect qualified and unqualified products into different frames, which is convenient for subsequent processing.

[0022] In this utility model, the visual inspection device for hot dome tiles can store a certain number of hot dome tiles through a feeding mechanism for continuous inspection. It can control the release of hot dome tiles in the placement cavity to ensure that only one hot dome tile can be pushed each time, thus achieving the effect of automatic feeding and improving applicability.

[0023] In this invention, the pot dome pieces can be pushed to both sides according to the test results, so as to change the collection path for unqualified pot dome pieces. Qualified and unqualified products can be collected into different frames, which is convenient for subsequent processing and achieves the purpose of classified storage. This is beneficial for the later retrieval and utilization of pot dome pieces and improves the applicability. Attached Figure Description

[0039] Example 2

[0040] refer to Figures 1-4 An improvement based on Embodiment 1: a visual inspection device for pot-shaped noodles, which is applied to the field of visual inspection devices;

[0041] The feeding mechanism is mounted on the support frame 1 and is used to automatically feed the dome switches to be inspected. The feeding mechanism includes a support block 5, a mounting frame 6, an electric push rod 7, a pushing frame 8, a placement frame 9, a placement cavity 10, a slide 11, and a baffle 12. The support block 5 is fixedly mounted on one side of the two support frames 1, the mounting frame 6 is fixedly mounted on the top side of the support block 5, and the placement frame 9 is fixedly mounted on the top side of the mounting frame 6. Both placement cavities 10 are opened on the top side of the mounting frame 6 and are used to store and place the dome switches to be visually inspected. The dome switches to be inspected are pre-placed in the placement cavity 10 at the top of the mounting frame 6. The placement cavity 10 is designed to store a certain number of dome switches for continuous inspection. Since there are two placement cavities 10, the dome switches in the placement cavity 10 can be controlled and released separately.

[0042] Two chutes 11 are located on both sides of the placement frame 9. Each baffle 12 is slidably connected to the inside of the chutes 11 for controlling the release of multiple stored hot dome switches. The baffle 12 controls the number of hot dome switches released. When one of the baffles 12 is open, the hot dome switch in one of the placement chambers 10 will automatically fall. The gap between the bottom side of the placement frame 9 and the top side of the mounting frame 6 can only accommodate one hot dome switch, ensuring that only one hot dome switch can be pushed at a time. An electric push rod 7 is fixedly installed on the inner wall of one side of the mounting frame 6. A push frame 8 is fixedly set at the output end of the electric push rod 7 for pushing and feeding the released hot dome switches. When the electric push rod 7 is activated, the push frame 8 connected to its output end moves forward, pushing a hot dome switch released at the bottom of the placement frame 9, so that the conveyor belt 3 can catch it and start moving towards the detection area, achieving the effect of automatic feeding.

[0043] The same automatic vision inspection instrument 4 is fixedly installed on the top side of the two support frames 1 for visual inspection of the hot dome. The automatic vision inspection instrument 4 is set between the feeding mechanism and the sorting mechanism. When the hot dome moves to the bottom of the automatic vision inspection instrument 4 with the conveyor belt, the instrument is activated. The instrument uses advanced visual recognition technology to perform all-round inspection of the hot dome, including multiple aspects such as size, shape, and surface defects. After the inspection is completed, the automatic vision inspection instrument 4 will determine whether the hot dome is qualified or unqualified according to the preset standard.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 2, the automatic vision inspection instrument 4, the electric push rod 7, and the second motor 14 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
