Description

Technical Field

[0001] This utility model belongs to the field of card production technology, and in particular relates to a card visual inspection device. Background Technology

[0002] Cards generally refer to flat, card-shaped sheets produced through printing and die-cutting, including playing cards and game cards. Currently, card sizes are measured on-site using calipers. However, due to the cards' susceptibility to deformation and variations in handling techniques, the measured values ​​can deviate significantly. There is currently no dedicated equipment for measuring card width. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing a card visual inspection device, which solves the problem of inaccurate manual caliper inspection and large deviations in measurement values.

[0004] In view of this, the present invention provides a card visual inspection device, including a base, on which are provided: A placement platform, used to place the cards to be tested; A pole, the top of which is fixedly connected to a vision inspection system including a camera; The camera is positioned directly above the placement platform to take pictures of the cards to be tested placed on the platform.

[0005] In this technical solution, the visual inspection system uses a camera to scan the cards placed on a platform. The analysis system then checks whether the card's size meets the requirements. If it does not, a three-color alarm light illuminates red; if it does, it illuminates green. This solves the problem of inaccurate measurements and large deviations when using calipers manually. The specific visual inspection system is commercially available and will not be described further in this application.

[0006] Furthermore, the placement platform is made of a light-transmitting material, and a backlight source is provided below the placement platform.

[0007] In this technical solution, the bright light from the backlight source passes through the light-transmitting material, creating a backlight effect on the card to be tested on the platform. This makes the outline of the card in the photo taken by the camera clearer and the size measurement more accurate.

[0008] Furthermore, the placement platform is made of translucent quartz glass.

[0009] Furthermore, the placement platform is equipped with an auxiliary structure to facilitate the removal of the cards after testing.

[0010] Furthermore, the auxiliary structure includes an auxiliary groove formed on the placement platform, the auxiliary groove extending from the edge of the placement platform toward the center.

[0011] Furthermore, the width of the auxiliary groove is greater than 1 cm.

[0012] In this technical solution, by opening an auxiliary slot, after the card detection is completed, a thumb can be inserted into the auxiliary slot to reach the bottom of the card. There are thumbs on both the top and bottom sides of the card, which can hold the card and remove it. This makes it easier to remove the card without rubbing it on the placement platform.

[0013] Furthermore, a detachable cover block is correspondingly provided in the auxiliary groove.

[0014] Furthermore, the size of the covering block is the same as that of the auxiliary groove.

[0015] Furthermore, magnetic blocks are provided on the walls of the auxiliary groove, and corresponding magnetic blocks are provided on the covering block.

[0016] In this technical solution, when the detection device is not in use, the cover block is inserted into the auxiliary slot to prevent dust from accumulating in the auxiliary slot and affecting the backlight source from passing through the placement platform. The magnetic blocks can keep the cover block stably in the auxiliary slot through magnetic attraction.

[0017] Furthermore, the camera is connected to the pole via a dovetail joint structure and secured with a locking nut.

[0018] The beneficial effects of this utility model are: 1. The visual inspection system uses a camera to scan the cards placed on the platform. The system analyzes whether the size of the cards meets the requirements. If the size does not meet the requirements, a three-color alarm light will turn red; if the size meets the requirements, the light will turn green. This solves the problem of inaccurate measurement and large deviations in measurement values ​​when using calipers manually.

[0019] 2. By allowing the backlight to pass through the translucent material, the card being tested is backlit on the platform, making the card's outline clearer in the camera's photograph and thus improving the accuracy of size measurement.

[0020] 3. By creating an auxiliary slot, after the card detection is completed, a thumb can be inserted into the auxiliary slot to reach under the card. With thumbs on both the top and bottom of the card, the card can be gripped and removed. This makes it easier to remove the card without rubbing it on the placement platform.

Additionally, features described with reference to certain examples may be combined in other examples.

[0028] Example 1: like Figure 1-4 As shown, A card visual inspection device includes a base 1, on which: Placement platform 2, which is used to place the cards to be tested; The pole 3 has a visual inspection system, including a camera 4, fixedly connected to its top; Camera 4 is positioned directly above the placement platform 2 and is used to take pictures of the cards to be tested placed on the placement platform 2.

[0029] The visual inspection system uses four cameras positioned below the cards on the platform 2 to check if their dimensions meet requirements. If not, a red alarm light (10) illuminates; if the dimensions are within acceptable limits, a green light illuminates. This solves the problem of inaccurate measurements and large deviations caused by manual caliper use. The specific visual inspection system is commercially available and will not be described further in this application.

[0030] The placement platform 2 is made of a light-transmitting material, and a backlight source is installed below the placement platform 2. The light from the backlight source passes through the light-transmitting material, creating a backlight effect on the card to be tested on the placement platform 2. This allows the outline of the card in the photo taken by the camera 4 to be clearer, making the size measurement more accurate.

[0031] The placement platform 2 is made of translucent quartz glass. An auxiliary structure is provided on the placement platform 2 to facilitate the removal of the cards after testing. The auxiliary structure includes an auxiliary groove 5 formed on the placement platform 2, extending from the edge of the placement platform 2 towards the center. The width of the auxiliary groove 5 is greater than 1 cm.

[0032] By opening the auxiliary slot 5, after the card detection is completed, a thumb can be inserted into the auxiliary slot 5 to reach the bottom of the card. There are thumbs on both the top and bottom of the card, which can hold the card and remove it. This makes it easier to remove the card without rubbing it on the placement platform 2.

[0033] A detachable cover block 6 is correspondingly provided inside the auxiliary groove 5. The cover block 6 is the same size as the auxiliary groove 5. Magnetic blocks 7 are provided on the wall of the auxiliary groove 5, and the cover block 6 is provided with corresponding magnetic blocks 7. When the detection device is not in use, the cover block 6 is inserted into the auxiliary groove 5 to prevent dust from accumulating in the auxiliary groove 5 and affecting the transmission of the backlight source to the placement platform 2. Furthermore, the magnetic attraction of the magnetic blocks 7 allows the cover block 6 to be stably held inside the auxiliary groove 5.

[0034] The camera 4 and the pole 3 are connected by a dovetail groove structure 8 and fixed by a locking nut 9.

[0035] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
