Description

Technical Field

[0001] This utility model belongs to the field of circuit board testing technology, specifically relating to a two-dimensional hole detection device for circuit boards. Background Technology

[0002] The background technology for double-sided hole inspection of circuit boards mainly involves the demand for high-quality and high-efficiency inspection in the circuit board manufacturing industry, as well as the limitations of existing inspection technologies. With the continuous upgrading and replacement of electronic products, circuit boards, as core components of electronic products, have increasingly higher requirements for manufacturing precision and quality. Holes on circuit boards are crucial for connecting circuits between different layers, and the accuracy of their position and size directly affects the electrical performance and reliability of the circuit board. Therefore, efficient and accurate inspection of double-sided holes on circuit boards has become an important requirement for the circuit board manufacturing industry.

[0003] For example, a Chinese patent discloses a detection device for detecting the hole positions of a circuit board (publication number CN218297084U). This patent relates to the field of detection device technology. By placing the circuit board between two clamping blocks and continuing to press down on the circuit board, the circuit board slides into the opening of the two clamping blocks, thus quickly clamping and fixing the circuit board. This achieves the fixation of most circuit boards, thereby reducing the phenomenon of deviation during circuit board movement, ensuring the detection effect, eliminating the need for multiple manual corrections, and bringing convenience to the user.

[0004] Based on the analysis of existing patents, when inspecting the two-sided face of a circuit board, the existing technology places the circuit board on the surface of the adjustment frame and limits it with limiters on both sides. The adjustment frame moves the circuit board, which helps the detection probe to inspect both sides of the circuit board. However, after the circuit board is drilled, some drilling debris will remain on the inner wall of the hole, which will affect the detection effect of the detection probe and affect the accuracy of the detection. Therefore, this utility model provides a two-dimensional hole detection device for circuit boards. Utility Model Content

[0005] The purpose of this invention is to provide a two-way face detection device for circuit boards, which can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows: A double-sided face detection device for circuit boards includes a worktable, a display screen mounted on the surface of the worktable, a detection probe fixedly connected to the surface of the worktable, an adjustment frame fixedly connected to the surface of the worktable, two limiters mounted on the surface of the adjustment frame, a circuit board body slidably connected to the surface of the adjustment frame, a cleaning device on the surface of the detection probe, and a stacking device on the surface of the worktable. The cleaning device includes two extension plates, both of which are fixedly connected to the sidewalls of the detection probe. A round rod is fixedly connected to the lower surface of each of the two extension plates. An extension frame is slidably connected to the end of the round rod away from the extension plate.

[0010] The present invention is further configured such that: the stacking device includes a square frame, the square frame is fixedly connected to the upper surface of the workbench, a foam board is slidably connected to the inner wall of the square frame, and a plurality of insert rods are slidably connected to the surface of the foam board, the cross-section of the plurality of insert rods being tapered.

[0011] The present invention is further configured such that: a connecting seat is fixedly connected to the side wall of the frame, a bidirectional screw is fixedly connected to the surface of the connecting seat, and two limiting brackets are threadedly connected to the surface of the bidirectional screw, and both limiting brackets are slidably connected to the surface of the frame.

[0012] The present invention is further configured such that: each of the surfaces of the two limiting frames is rotatably connected to a plurality of auxiliary wheels, and the plurality of auxiliary wheels are arranged in a vertical linear array on the surface of the limiting frame.

[0013] The technical effects achieved by this utility model are as follows: This utility model discloses a double-hole position detection device for circuit boards. When the adjustment frame moves the circuit board to adjust its position, the brush can enter the opened hole to clear debris inside the connected hole, making it easier for the detection probe to take pictures and detect, and further improving the accuracy of the detection.

[0014] This utility model discloses a double-sided hole alignment inspection device for circuit boards, which allows workers to neatly stack batches of inspected circuit boards together. It is easy to operate and can use various types of circuit boards. Workers do not need to visually inspect and align the circuit boards after hole inspection, which facilitates the transfer and use of circuit boards during processing. Attached Figure Description

[0017] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figure 1 As shown, a double-sided face detection device for circuit boards includes a workbench 1, a display screen 2 mounted on the surface of the workbench 1, a detection probe 3 fixedly connected to the surface of the workbench 1, an adjustment frame 4 fixedly connected to the surface of the workbench 1, two limiters 5 mounted on the surface of the adjustment frame 4, a circuit board body 6 slidably connected to the surface of the adjustment frame 4, a cleaning device 7 provided on the surface of the detection probe 3, and a stacking device 8 provided on the surface of the workbench 1.

[0019] In this embodiment of the utility model: when the circuit board body 6 is being inspected, the operator can place the circuit board body 6 on the surface of the adjustment frame 4. At this time, the limiter 5 can limit the circuit board. Furthermore, by adjusting the position of the moving plate on the surface of the adjustment frame 4, the position of the circuit board body 6 can be changed. At the same time, in conjunction with the detection probe 3 and the display, the condition of the two-sided face of the circuit board body 6 can be quickly understood to achieve the detection effect. After the inspection, the circuit boards can be neatly arranged together by the stacking device 8.

[0020] like Figures 1-3 As shown, the cleaning device 7 includes two extension plates 701, both of which are fixedly connected to the side wall of the detection probe 3. A round rod 702 is fixedly connected to the lower surface of each of the two extension plates 701. An extension frame 704 is slidably connected to the end of the round rod 702 away from the extension plate 701. A cylinder 706 is rotatably connected to the surface of the extension frame 704. A plurality of bristles 708 are fixedly connected to the surface of the cylinder 706. The plurality of bristles 708 are linearly arrayed on the arc surface of the cylinder 706.

[0021] During the movement and adjustment process, the circuit board body 6 will come into contact with the brush bristles 708, and the brush bristles 708 can help clean the dust inside the holes of the circuit board body 6.

[0022] A spring 703 is fitted on the surface of the round rod 702. The two ends of the spring 703 are fixedly connected to the extension plate 701 and the extension frame 704 respectively. The spring 703 can drive the extension frame 704 to move downward, which can compress the bristles 708 on the surface of the circuit board body 6. When it encounters a hole, it can directly spring into the hole. A drive wheel 705 is fixedly connected to one end of the cylinder 706. Two rotating wheels 707 are rotatably connected to the surface of the drive wheel 705. The drive wheel 705 and the two rotating wheels 707 are all made of rubber.

[0023] When the circuit board body 6 is adjusted, the drive wheel 705 can contact the surface of the circuit board, and due to the special material of the drive wheel 705, it can drive the cylinder 706 to rotate. The rotating bristles 708 can help clean the debris inside the holes better, improving the cleaning effect. There is a rotating wheel 707 on the surface of the drive wheel 705, which can prevent the drive wheel 705 from getting stuck when it moves back and forth on the circuit board.

[0024] Several bristles 708 are all in a "J" shape, and one end of each bristle 708 is fixedly connected to a ball 709. The surface of the ball 709 is coated with an adhesive layer. Since some non-connected holes are made when the circuit board is drilled, the special shape of the bristles 708 can hook out the debris. In addition, the adhesive effect of the ball 709 greatly improves the convenience of hooking out the debris and increases the ease of cleaning the surface of the circuit board.

[0025] The working principle of this utility model is as follows: The circuit board body 6 is placed on the surface of the adjustment frame 4. Simultaneously, the limiter 5 restricts the position of the circuit board body 6. The operator can then manipulate the adjustment frame 4 to adjust the position of the circuit board body 6. During this adjustment, the detection probe 3 moves with the circuit board body 6 to detect holes on the circuit board. As the circuit board body 6 moves, the rotating wheel presses against its surface. During this movement, the drive wheel 705 rotates the cylinder 706, causing the bristles 708 to contact the holes. The special structure of the bristles 708 and the connected ball 709 help clean debris from the inner walls of the holes on the surface of the circuit board body 6, facilitating the detection process and improving accuracy.

[0026] like Figure 1 and Figure 4 As shown, the stacking device 8 includes a frame 801, which is fixedly connected to the upper surface of the workbench 1. A foam board 802 is slidably connected to the inner wall of the frame 801, and a number of insert rods 807 are slidably connected to the surface of the foam board 802. The cross-section of the insert rods 807 is tapered.

[0027] When stacking the main body of the circuit board 6, first place the bottom circuit board, and then insert the insertion rod 807 along the holes on the surface of the circuit board 802. At this time, the subsequent main body of the circuit board 6 can slide directly with the surface of the insertion rod 807 to achieve the stacking effect.

[0028] A connecting seat 803 is fixedly connected to the side wall of the frame 801. A bidirectional screw 804 is fixedly connected to the surface of the connecting seat 803. Two limit brackets 805 are threadedly connected to the surface of the bidirectional screw 804. Both limit brackets 805 are slidably connected to the surface of the frame 801.

[0029] When stacking the main body of the circuit board 6, the two-way screw 804 can be rotated to adjust the two limiting brackets 805 to both sides of the main body of the circuit board 6, which facilitates the subsequent placement of the main body of the circuit board 6.

[0030] Several auxiliary wheels 806 are rotatably connected to the surfaces of the two limit frames 805, and the auxiliary wheels 806 are arranged in a vertical linear array on the surface of the limit frame 805.

[0031] When placing the circuit board body 6 along the inner wall of the limiting frame 805, the auxiliary wheel 806 can reduce the degree of jamming when the circuit board slides down, thereby increasing the placement speed of the circuit board body 6.

[0032] The working principle of this utility model is as follows: After testing, the main body 6 of the circuit board can be placed on the surface of the foam board 802. Then, the operator can rotate the bidirectional screw 804, which drives the two limiting brackets 805 to abut against both sides of the main body 6 of the circuit board, thus initially limiting the circuit board. Then, the insertion rod 807 is inserted into the surface of the foam board 802 along the hole connected to the surface of the main body 6 of the circuit board. After the hole testing of the same type of circuit board is completed, it can slide down directly with the insertion rod 807. The insertion rod 807 is conical, which makes it easy for the operator to insert and place it. When the main body 6 of the circuit board slides down along the inner wall of the limiting bracket 805, the auxiliary wheel 806 can reduce the jamming during the slide and can quickly place it to the bottom.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
