Description

Technical Field

[0001] This utility model relates to the field of finished circuit board inspection technology, specifically a convenient adjustable table for inspecting finished circuit boards. Background Technology

[0002] After the circuit board is finished, it needs to be inspected using an inspection table. The circuit board inspection table is generally a regular light table with a magnifying glass added. Inspection on this kind of light table can meet the customer's requirements. However, in the traditional circuit board inspection table, the PCB is placed horizontally on the table. When inspecting each circuit board, the employee has to pick it up and adjust it to an angle with the magnifying glass. The employee has to do this for a long time, repeating the same action, which increases the labor intensity of the employee.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN220903283U, Publication Date: 2024-05-07) provides an adjustable circuit board semi-finished product testing platform. The platform body has an adjustment mechanism at one end, and the adjustment mechanism has a base. Through the cooperation between the platform body and the adjustment mechanism, without affecting the basic testing of the circuit board semi-finished product, the height of the testing platform can be freely adjusted via a mounting bracket through the cooperation of the motor, threaded rod, moving rod, and control rod within the adjustment mechanism. During installation, the positioning holes and slots ensure accurate positioning when connecting the platform to the mounting bracket. Furthermore, the protective layer on the platform effectively prevents static electricity from occurring during the testing process, thus improving the convenience and stability of the mechanism to a certain extent.

[0004] The aforementioned mechanism allows for the adjustment of the table height by utilizing the cooperation between the workbench and the adjustment mechanism. However, in actual use, different workers observe the finished circuit boards from different angles during inspection, and simply adjusting the height cannot reduce the labor intensity of workers when inspecting the circuit boards. Utility Model Content

[0005] The purpose of this utility model is to provide a convenient adjustable inspection table for finished circuit boards, in order to solve the problem mentioned in the background art that when using traditional inspection tables for finished circuit boards, the PCBs are placed horizontally on the table, and each circuit board must be picked up and adjusted to an angle with a magnifying glass for inspection. This process of repeated inspections increases the labor intensity of employees.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient adjustable inspection table for finished circuit boards, comprising a workbench, a fixed plate installed at the middle position of the top of the workbench, and a mounting frame slidably connected to the upper end of the fixed plate, an inspection table rotatably connected inside the mounting frame via a rotating rod, and a magnifying glass disposed above the inspection table, with placement racks disposed on both the left and right sides of the top of the workbench; an adjustment frame rotatably connected to the left and right sides of the rear end of the mounting frame via a rotating rod, and an adjustment mechanism for adjusting the angle of the inspection table disposed at the upper end of the adjustment frame, the adjustment mechanism including a limiting groove, the limiting groove being formed on the left and right sides of the inspection table, and the adjustment frame and the inspection table forming a sliding connection through the limiting groove; a fixed rod installed at the middle position of the rear end of the top of the workbench, and a lifting mechanism for adjusting the height of the magnifying glass disposed inside the fixed rod.

[0007] Furthermore, mounting plates are installed on both the left and right sides of the front end of the inspection table, and the sides of the adjustment frame are engaged with locking blocks. The sides of the mounting plates are provided with locking slots that match the locking blocks.

[0008] Furthermore, a connecting spring is wound around the outside of the locking block, and the locking block passes through the adjustment bracket and extends to the other side of the mounting plate.

[0009] Furthermore, the card slots are evenly spaced on the side of the mounting plate, and the diameter of the card slots is larger than the diameter of the left side of the card block.

[0010] Furthermore, the top surface of the fixing plate is provided with sliding grooves at both the front and rear ends, and the bottom end of the mounting frame is equipped with a slider that matches the sliding groove. The fixing plate and the mounting frame are connected by a sliding mechanism of sliding groove and slider.

[0011] Furthermore, the lifting mechanism includes a movable block, which is slidably connected to the inside of the fixed rod. An extension rod is installed at the top of the movable block, and the side of the extension rod is connected to the magnifying glass.

[0012] Furthermore, a drive gear is rotatably connected inside the fixed rod, and a rack meshes with the rear end of the drive gear. The rack and the fixed rod are slidably connected, and a handle is installed on the side of the drive gear extending to the outside of the fixed rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When using the inspection table, the angle adjustment range should be between 30° and 40°, and the angle adjustment range should be fine-tuned according to the user's needs, so that the angle of the inspection table can better meet the user's usage habits. Through the sliding connection between the adjustment frame and the limiting groove, when the adjustment frame slides inside the limiting groove, the tilt angle of the inspection table will be deflected, thereby adjusting the angle of the inspection table itself. The length of the limiting groove is the movable range of the adjustment frame, so that when the angle of the inspection table is adjusted, the deflection range will not exceed 30° to 40°.

[0015] Furthermore, by using a locking block on the outside of the adjustment frame to pass through the slot and limit the movement between it and the mounting plate, the angle of the inspection table can be restricted after adjustment, thus preventing the inspection table from deflecting under force and increasing the stability of the inspection table during use.

[0016] Furthermore, the locking block is connected to the adjusting frame via a connecting spring, so that after the locking block is pulled outward, the elastic force of the connecting spring can quickly reset it and engage with the appropriate locking slot, thus ensuring that the angle of the inspection table itself remains stable after deflection.

[0017] 2. A sliding connection is formed between the groove on the surface of the fixed plate and the slider, allowing the inspection table to slide left and right inside the groove. This allows the inspection table to be placed in a position that can be adjusted according to the user's habits, making the inspection table more flexible and convenient to use and increasing its adaptability.

[0018] Furthermore, by rotating the handle, the handle can drive the drive gear to rotate. When the drive gear rotates, it meshes with the rack, causing the rack to move up and down. The top of the rack is connected to the extension rod through a movable block, so the extension rod is pushed out and moves upward, thereby increasing the adjustable range of the extension rod to better adapt to different usage needs. At the same time, the movable block and the fixed rod are slidably connected, which makes the up and down movement of the rack more flexible, increasing the overall flexibility during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figures 1-3 and Figure 6The technical solution presented addresses the problem of traditional circuit board inspection workbenches where PCBs are placed horizontally, requiring employees to lift each board and adjust it to a magnifying glass for inspection, increasing their workload due to repetitive actions. This convenient adjustable circuit board inspection workbench discloses an adjustment mechanism, including a workbench 1. A fixing plate 2 is installed at the center of the top of the workbench 1, and a mounting bracket 5 is slidably connected to the upper end of the fixing plate 2. An inspection table 6 is rotatably connected inside the mounting bracket 5 via a rotating rod, and a magnifying glass 13 is installed above the inspection table 6. Placement racks 20 are located on the left and right sides of the top of the workbench 1. The rear left and right sides of the mounting bracket 5... An adjusting frame 7 is rotatably connected to both sides via a rotating rod. The upper end of the adjusting frame 7 is provided with an adjusting mechanism for adjusting the angle of the inspection table 6. The adjusting mechanism includes a limiting groove 12, which is opened on the left and right sides of the inspection table 6. The adjusting frame 7 and the inspection table 6 are slidably connected through the limiting groove 12. Mounting plates 8 are installed on both the left and right sides of the front end of the inspection table 6. A locking block 10 is engaged with the side of the adjusting frame 7. The side of the mounting plate 8 is provided with a locking groove 9 that matches the locking block 10. A connecting spring 11 is wound around the outside of the locking block 10. The locking block 10 passes through the adjusting frame 7 and extends to the other side of the mounting plate 8. The locking grooves 9 are evenly spaced on the side of the mounting plate 8, and the diameter of the locking grooves 9 is larger than the diameter of the left side of the locking block 10.

[0028] In this example, when inspecting finished circuit boards, the circuit boards to be inspected are placed on the surface of the inspection table 6. The magnifying glass 13 magnifies the finished circuit boards, facilitating inspection by the staff. Placement racks 20 are located on both sides of the top of the workbench 1, allowing different states of finished circuit boards to be placed on them. The left placement rack 20 holds the finished circuit boards to be inspected, while the right placement rack 20 holds the finished circuit boards that have passed inspection, making the inspection of finished circuit boards more convenient. The angle adjustment range of the inspection table 6 should be between 30° and 40° during use, and the angle adjustment range should be fine-tuned according to the user's needs, so that the angle of the inspection table 6 better suits the user's habits. Through the sliding connection between the adjusting frame 7 and the limiting groove 12, the adjusting frame 7 is positioned within the limiting groove 12. 2. When sliding internally, the tilt angle of the inspection table 6 will be deflected, thereby allowing the angle of the inspection table 6 to be adjusted. The length of the limiting groove 12 is the movable range of the adjusting frame 7, so that the angle of the inspection table 6 will not deflect more than 30° to 40° when adjusting the angle. Furthermore, the locking block 10 set on the outside of the adjusting frame 7 passes through the locking groove 9 and limits the angle between it and the mounting plate 8, thereby limiting the angle of the inspection table 6 after adjustment and preventing the angle of the inspection table 6 from deflecting under force, thus increasing the stability of the inspection table 6 during use. At the same time, the locking block 10 is connected to the adjusting frame 7 through the connecting spring 11, so that after the locking block 10 is pulled outward, the elastic force of the connecting spring 11 can quickly reset it and lock it with the appropriate locking groove 9, thereby ensuring that the angle of the inspection table 6 remains stable after deflection.

[0029] Example 2: Figure 1 and Figure 2 The technical solution shown addresses the problem that the position of the inspection table 6 is not easily adjusted according to the different usage habits of the staff when inspecting circuit boards, resulting in low overall flexibility during use. The convenient adjustable circuit board finished product inspection table discloses a moving mechanism. The front and rear ends of the top surface of the fixed plate 2 are provided with sliding grooves 3, and the bottom end of the mounting frame 5 is equipped with a slider 4 that matches the sliding grooves 3. The fixed plate 2 and the mounting frame 5 are connected by the sliding mechanism of the sliding grooves 3 and the slider 4.

[0030] In this example, the sliding connection between the groove 3 on the surface of the fixed plate 2 and the slider 4 is formed, so that the inspection table 6 can slide left and right inside the groove 3 via the slider 4. This allows the inspection table 6 to be placed in a position that can be adjusted according to the user's own habits, making the use of the inspection table 6 more flexible and convenient, and increasing the flexibility of use.

[0031] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 5 The technical solution shown addresses the problem that the height of the magnifying glass 13 is difficult to adjust during circuit board inspection, making it unsuitable for different viewing angles of different personnel. This convenient adjustable circuit board inspection table discloses a lifting mechanism. A fixed rod 15 is installed at the middle of the rear end of the top of the workbench 1, and the fixed rod 15 contains a lifting mechanism for adjusting the height of the magnifying glass 13. The lifting mechanism includes a movable block 16, which is slidably connected to the inside of the fixed rod 15. An extension rod 14 is installed at the top of the movable block 16, and its side is connected to the magnifying glass 13. A drive gear 17 is rotatably connected inside the fixed rod 15, and a rack 18 meshes with the rear end of the drive gear 17. The rack 18 is slidably connected to the fixed rod 15, and a handle 19 is installed on the side of the drive gear 17 extending to the outside of the fixed rod 15.

[0032] In this example, by rotating the handle 19, the handle 19 drives the drive gear 17 to rotate. When the drive gear 17 rotates, it meshes with the rack 18, causing the rack 18 to move up and down. The top of the rack 18 is connected to the extension rod 14 through the movable block 16, thus pushing the extension rod 14 out and moving it upward. This increases the adjustable range of the extension rod 14, making it easier to adapt to different usage needs. At the same time, the movable block 16 and the fixed rod 15 are slidably connected, making the up and down movement of the rack 18 more flexible and increasing the overall flexibility during use. The extension rod 14 itself has a certain degree of plasticity, so it can be bent and adjusted to the left and right sides during actual use, so that the extension rod 14 can always be positioned above the finished circuit board, facilitating better inspection of the finished circuit board.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
