Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, and particularly relates to a steel mesh detection device. Background Art

[0002] Industrial manufacturing refers to an industry that uses certain resources (such as materials, energy, equipment, tools, and manpower, etc.) and, according to market requirements, through a manufacturing process, transforms them into tools, industrial products, and consumer products for people to use and utilize. Screen printing is a printing technology that uses the principle that the mesh holes in the graphic part of the screen printing plate are ink-permeable and the mesh holes in the non-graphic part are ink-impermeable. It has the advantages of simple equipment, convenient operation, low cost, and strong adaptability. It is suitable for various types of printing substrates, such as circuit boards, paper, textiles, ceramics, metals, etc., and is also suitable for flat and curved surfaces. Therefore, it is widely used in industrial manufacturing. In the field of electronic manufacturing, SMT screen printing technology can also be used to accurately print conductive ink onto circuit boards, with extremely high requirements for accuracy and stability. When the screen printing steel mesh is in use, it needs to be inspected to avoid problems such as blockage of the steel mesh, which affects the printing effect and causes the product quality to fail to meet the design requirements. Currently, when inspecting the steel mesh, generally, a staff member holds the steel mesh against the light to check whether all the mesh holes of the steel mesh are light-transmitting. Such an operation is inconvenient when inspecting a relatively large-sized steel mesh. Therefore, a device that can assist in the inspection of the steel mesh is needed. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a steel mesh detection device.

[0022] Embodiment 1

[0023] Refer to Figures 1 to 3, the present utility model provides a stencil inspection device, which includes a frame 1, a fixed frame 2 arranged on the frame 1, a limit support frame 3 arranged inside the fixed frame 2, a backlight assembly 4 connected to the fixed frame 2, and an electrical box 5.

[0024] The backlight assembly 4 includes a backlight bottom plate 41, a lighting source 42 arranged on the backlight bottom plate 41. One side of the backlight bottom plate 41 is rotatably connected to the inner side wall of one side frame of the fixed frame 2, and the opposite side of the backlight bottom plate 41 is connected to the fixed frame 2 through a connection assembly 6. The backlight bottom plate 41 is located below the limit support frame 3, and a transparent cover plate 7 is arranged on the limit support frame 3.

[0025] The connection assembly 6 includes a buckle 61 arranged on one side of the backlight bottom plate 41, and a fastening member 62 arranged at the bottom of one side frame of the fixed frame 2 and matching with the buckle 61.

[0026] The lighting system is carefully designed and consists of a series of equally spaced and parallel arranged lamp strips to ensure the uniformity of light source distribution. In this embodiment, we selected high-efficiency and energy-saving LED lamp strips, with a total of twenty configured and carefully arranged to achieve uniform light coverage of the entire transparent cover plate 7 area, providing a bright and consistent lighting effect. At the same time, the LED lamp strips can achieve stepless dimming, which is convenient for the staff to adjust the appropriate color temperature. In addition, since the backlight bottom plate 41 is ingeniously connected to the fixed frame 2 through a rotational connection design on one side, when the internal lamp strips need to be maintained or malfunction, the bottom plate can be easily flipped downwards. Such a design can not only quickly expose the internal lamp strips, but also greatly facilitate the operators to inspect and maintain the lamp strips, improving the maintenance efficiency, reducing the complexity of operation and potential safety risks.

[0027] In this embodiment, the electrical box 5 is ingeniously designed and connected to the bottom surface of the backlight bottom plate 41, such a layout is convenient for achieving convenient electrical connection with the lamp strips on the bottom plate.

[0030] Connection holes 44 for connecting the fastener 43 are provided at the corners of the backlight bottom plate 41, and mounting holes are also provided at the corresponding positions of the limit bearing frame. After the backlight bottom plate 41 is rotated to the horizontal position, the fastener 43 is connected to the mounting hole to lock the backlight bottom plate 41 and the limit bearing frame. Then, the buckle 61 and the buckling part are connected, so that the backlight bottom plate 41 is double-locked to ensure the firmness of the connection. In addition, mounting holes are also provided at the corresponding positions on the rear side of the backlight bottom plate 41. In specific implementation, in order to further ensure the firmness of the connection, fasteners 43 can be provided at all four corners of the backlight bottom plate 41.

[0031] In this embodiment, the backlight bottom plate 41 and the fixed frame 2 are connected by a hinge 45, allowing the bottom plate and the frame to rotate flexibly. To adapt to different installation requirements and environments, other connection schemes are also considered, such as using a rotating shaft and other structures to ensure the diversity and adaptability of the connection. This design not only provides a convenient way for adjustment and maintenance but also enhances the stability and durability of the overall structure.
