[0004] With the development of industries such as consumer electronics and new energy, the market demand for flexible circuit boards is increasing. During the production of flexible circuit boards, quality control of the circuit boards is required.

However, the appearance inspection of flexible circuit boards on the market currently mainly uses front lighting and adsorption imaging inspection using platforms made of ordinary aluminum alloys and other materials. This can only image surface defects of the circuit boards and cannot effectively detect hole blockage, hole burr defects, and hole diameter measurement. This has significant limitations in the inspection of flexible circuit boards. The existing backlight adsorption platform has a relatively complex structural design, multiple parts, and poor overall heat dissipation. Long-term use may burn out the entire device.

[0032] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] Example 1

[0034] See also Figures 1 to 5 , a backlight FPC adsorption detection device with easy heat dissipation, including a platform base 4 for connecting the entire device into a whole, the platform base 4 is provided with a base cavity 47 for accommodating the internal structure and facilitating the formation of negative pressure, the base cavity 47 is provided with a light-emitting device 3 for providing sufficient brightness to measure hole defects in the product, the top of the base cavity 47 is provided with an adsorption device 1 that closes the base cavity 47 and is used to adsorb the FPC board, the platform base 4 is provided with an air path device 41 that is connected to the base cavity 47 and generates negative pressure in the base cavity 47, the device has a simple design structure, the equipment is relatively lightweight and compact, and is easy to use on a production line or a test bench, the platform base is designed with heat dissipation stripes, which can ensure that the heat generated by the entire device, especially the light-emitting panel, can be effectively dissipated, which is crucial to maintaining the stable operation of the system and extending its service life.

[0035] Furthermore, as a preferred embodiment of this solution, but not a limitation, the heat dissipation stripes 42 are concave-convex in shape, parallel to the long sides of the platform base 4, and evenly distributed between the air path devices 41. The platform base incorporates these concave-convex heat dissipation stripes. These stripes not only increase the surface area but also optimize the air flow path, thereby improving heat dissipation efficiency. Heat generated by the high-brightness light source during operation is quickly dissipated through these stripes, effectively preventing overheating and ensuring the stability and durability of the light source.

[0036] Furthermore, as a preferred embodiment of the present invention but not a limitation thereof, the platform base 4 is provided with two mounting brackets 46 for stably mounting the platform base 4 and is also provided with an interface 43 for connecting the power supply of the light-emitting device 3. The air path device 41 includes four air pipes 411 interconnected with the base cavity 47. The air path device 41 is provided at the four corners of the platform base 4. The bottom of the adsorption device 1 and the top of the platform base 4 are interconnected to close the side of the base cavity 47. The platform base 4 is provided with a mounting bracket for quick installation on the equipment, which greatly simplifies the process of assembling and debugging the equipment, improves the installation efficiency of the equipment, makes the deployment of the machine more convenient, reduces downtime, and improves the flexibility and response speed of the production line. The light source power cord is cleverly connected from the bottom of the light source. This design not only saves side space, but also makes the overall equipment more compact and lightweight. The air path device is equipped with four air path pipe interfaces, which can efficiently connect and distribute the gas source to meet the air pressure requirements of the device. This design not only improves the stability and reliability of the air system, but also makes the air pressure supply more uniform and controllable, helping to maintain the consistency and accuracy of the FPC board adsorption process.

[0037] Furthermore, as a preferred embodiment of the present invention but not a limitation, a support plate 2 is provided between the light-emitting device 3 and the adsorption device 1 for supporting the adsorption device 1 and eliminating slight deformation of the adsorption device 1 due to adsorption. The support plate 2 is a plate structure and is installed on the step of the platform base 4. The support plate 2 is a milky white support plate. If there is no support plate 2, the thickness of the light-emitting device needs to be increased, resulting in increased manufacturing costs. If there is a support plate 2, the adsorption panel can be firmly supported, eliminating slight deformation of the panel due to adsorption, reducing interference with imaging, and can also transmit light to avoid blocking the light path and affecting imaging.

[0038] Furthermore, as a preferred embodiment of this solution but not limiting, the adsorption device 1 is a plate having a plurality of first adsorption holes 11 thereon that connect the upper surface of the plate with the base cavity 47. The adsorption device 1 is connected to the platform base 4 to form a closed-side integral body. The high-precision adsorption holes on the panel can firmly adsorb the material, greatly improving the stability of imaging.

[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, the light-emitting device 3 is a light-emitting panel having a rectangular structure. The light-emitting device 3 can provide sufficient brightness to measure defects such as holes in the product and has a certain adsorption capacity.

[0040] Example 2

[0041] See also Figure 6-7 This embodiment is based on the first embodiment, and a support member 6 for supporting the light emitting device 3 is provided between the platform base 4 and the light emitting device 3, and the support member 6 further strengthens the stability of the entire device.

[0042] The remaining structures are the same as those in the first embodiment and will not be described again here.

[0043] The working principle of this embodiment is as follows:

[0044] The invention discloses a usage process of an FPC adsorption detection device with easy heat dissipation for backlight. The light source power supply of the light-emitting device 3 is turned on, so that the light-emitting device 3 emits light to illuminate the FPC board on the back. The air path device 41 of the base 4 is turned on, and the first adsorption hole 11 of the adsorption device 1 inhales gas from the air. When a condition lower than the external atmospheric pressure is created inside a closed space, the external atmospheric pressure will push air or other fluids into this space, trying to balance the pressure difference. By utilizing this pressure difference, the adsorption or holding of external objects can be achieved. The backlight adsorption device forms an air pressure difference to lock the FPC board. Concave and convex heat dissipation stripes are added to the base part to increase the heat dissipation capacity of the high-brightness light source, ensuring that the backlight adsorption device can be used for a long time.

[0045] The above are implementation methods provided in conjunction with specific content, and the specific implementation of this application is not limited to these descriptions. Any method structure that is similar to the method structure of this application, or any technical deduction or replacement based on the concept of this application, should be considered as the scope of protection of this application.
