[0002] In the field of circuit board manufacturing, traditional testing methods typically rely on manual operation and fixed-height inspection equipment. Specifically, traditional workbenches use fixed-position levers and inspection devices, requiring operators to manually place the circuit board in the designated position and perform testing through manual observation or simple mechanical inspection. The shortcomings of this method are: firstly, manual positioning and inspection are prone to errors, resulting in low testing accuracy; secondly, fixed-height inspection equipment cannot accommodate circuit boards of different sizes, limiting the equipment's applicability; furthermore, it involves significant manual intervention, is cumbersome, and leads to low production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a workbench for circuit board processing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a worktable for circuit board processing, comprising:

[0005] The equipment platform has a conveyor belt installed inside. A fourth rotary drive is installed on the outer wall of one end of the equipment platform, and the output end of the fourth rotary drive is fixedly connected to the drive end of the conveyor belt. An equipment frame is fixed on one side of the equipment platform, and one end of the equipment frame extends to the top of the equipment platform. An infrared camera is installed below the equipment frame. A third rotary drive is installed on the top of the equipment platform below the infrared camera, and a stop bar is fixed to the output end of the third rotary drive.

[0006] A lifting mechanism is provided, which is located at the top of the equipment frame. The lifting mechanism includes a lifting housing, a lead screw, a first rotary drive component, and a movable arm. The lifting housing is fixed to the top of the equipment frame. The lead screw is mounted on one side inside the lifting housing via a bearing. The first rotary drive component is mounted on the top of the lifting housing at the position of the lead screw, and its output end extends into the interior of the lifting housing and is fixedly connected to the lead screw. The movable arm is fitted onto the outer wall of the lead screw and is threadedly connected to the lead screw. The bottom end of the movable arm extends to the bottom of the equipment frame and is connected to an infrared camera via bolts.

[0007] Preferably, a sorting rack is fixed to the other end of the equipment platform, and the sorting rack is provided with a first ramp channel and a second ramp channel inside for unloading the circuit board after inspection.

[0008] Preferably, a guide mechanism is provided at the center of the sorting rack, and the guide mechanism includes a support base and a rotating rod. The support base is fixed at the center of the bottom of the sorting rack, and the rotating rod is mounted on the top of the support base through a bearing. The bottom end of the rotating rod extends to the bottom of the sorting rack to facilitate the sorting of circuit boards.

[0009] Preferably, a sensor is installed on the top of the equipment platform on one side of the stop lever to facilitate sensing the position of the circuit board.

[0010] Preferably, the guiding mechanism further includes a guide plate, which is fitted onto the outer wall of the rotating rod and is fixedly connected to the rotating rod by bolts. One end of the guide plate extends to one end of the conveyor belt to facilitate the guiding of the circuit board.

[0011] Preferably, a second rotary drive is installed below the sorting rack at the location of the guide mechanism, and the output end of the second rotary drive is fixedly connected to the bottom end of the rotating rod for driving the rotating rod.

[0012] This utility model provides a worktable for circuit board processing, which has the following significant advantages compared with the prior art:

[0013] A third rotary drive unit rotates the stop lever, which precisely positions the circuit board, ensuring its fixed position on the conveyor belt and avoiding testing errors caused by positional deviations. This positioning mechanism keeps the circuit board stable during testing, significantly improving testing accuracy.

[0014] Infrared cameras can quickly and accurately detect various parameters of circuit boards, greatly improving testing efficiency compared to traditional manual testing methods.

[0015] This invention designs an adjustable-height infrared camera system. When testing circuit boards of different sizes, the controller activates the first rotary drive component, which in turn drives the lead screw to rotate, causing the movable arm to move up and down inside the lifting housing, thereby synchronously moving the infrared camera up and down. This height adjustment mechanism can flexibly adapt to the testing needs of circuit boards of different sizes, expanding the applicability of the equipment.

[0016] The height of the infrared camera can be adjusted with simple operation, which reduces the tedious steps of changing equipment or adjusting the test platform and improves production efficiency.

This design makes the equipment more flexible in application on different production lines, reducing the investment and maintenance costs for enterprises using multiple types of equipment.

[0018] The modular design of the equipment makes it easy to replace and maintain the components, extending the service life of the equipment and reducing maintenance costs.

[0019] The sensor automatically detects the presence of the circuit board, triggering the lever positioning and infrared camera testing. The entire process is highly automated, reducing manual intervention and the possibility of human error.

[0020] Automated workflows not only improve production efficiency but also reduce the labor intensity of workers and improve the working environment.

[0021] By improving testing accuracy and efficiency, the scrap rate caused by inaccurate testing was reduced, saving raw materials and production costs.

[0022] The automated and intelligent design of the equipment reduces energy consumption and meets the environmental protection requirements of energy conservation and emission reduction.

[0023] In summary, the circuit board processing workbench of this utility model effectively solves the problems of low testing accuracy, poor adaptability, and excessive manual intervention in the prior art through innovative design and technical means, significantly improving the efficiency and accuracy of circuit board processing, and has broad application prospects and market value.

[0066] The lifting mechanism 4 is located at the top of the equipment frame 2. The lifting mechanism 4 includes a lifting housing 401, a lead screw 402, a first rotary drive component 403, and a movable arm 404. The lifting housing 401 is fixed to the top of the equipment frame 2. The lead screw 402 is installed on one side inside the lifting housing 401 through a bearing. The first rotary drive component 403 is installed at the top of the lifting housing 401 at the position of the lead screw 402, and the output end of the first rotary drive component 403 extends into the interior of the lifting housing 401 and is fixedly connected to the lead screw 402. The movable arm 404 is fitted on the outer wall of the lead screw 402 and is threadedly connected to the lead screw 402. The bottom end of the movable arm 404 extends to the bottom of the equipment frame 2 and is connected to the infrared camera 3 by bolts.

[0067] The other end of the equipment platform 1 is fixed with a sorting rack 5, and the sorting rack 5 is provided with a first ramp channel 501 and a second ramp channel 502, which are used for unloading after the circuit board is tested.

Figure 2Guided by the guide plate 1203, the circuit board is exported through the first ramp channel 501. If the circuit board is unqualified, the second rotary drive 6 drives the rotating rod 1202 to rotate the guide plate 1203 to the left side of one end of the conveyor belt 7, and the circuit board is exported through the second ramp channel 502, which facilitates automatic sorting of the circuit boards and saves manpower and resources. Then, when it is necessary to test circuit boards of different specifications, the height of the infrared camera 3 is adjusted according to the size of the circuit board. During adjustment, the controller controls the first rotary drive 403 to work, and the first rotary drive 403 drives the lead screw 402 to rotate, so that the movable arm 404 moves up and down inside the lifting box 401. The movable arm 404 drives the infrared camera 3 to move up and down synchronously, so that the height of the infrared camera 3 can be adjusted, thereby meeting the testing needs of circuit boards of different specifications and having a wide range of applications.
