Description

Technical Field

[0001] The utility model relates to the technical field of circuit board measurement, in particular to a measurement device for printed circuit boards. Background Technique

[0002] The circuit board is one of the most basic components in electronic products. In order to ensure the performance and quality of the circuit board, various measurements are required. These measurement data are the basis for determining whether the circuit board meets the specifications and requirements, so they play a crucial role. After the surface layer of the circuit board is processed, it is necessary to detect the overall size and mechanical properties of the circuit board. Therefore, a measurement device for printed circuit boards is used to detect the circuit.

[0003] Existing technologies such as the patent with the publication number CN220689972U disclose a measurement device for printed circuit boards. This patent uses a base, and symmetrically distributed notches are opened on the base. Round rods are fixedly connected at the notches, and the round rods are slidably connected to the sliding holes opened on the push plate. A fixed block is fixedly connected to the base, and a second scale is provided on the fixed block. A first scale is opened on the base, and the thickness of the circuit board is measured through a matching part on the base; the device of the utility model solves the problems that when the existing device measures the circuit board, manual detection is used. When manually measuring, when using a measuring ruler to measure the length, width and height of the printed circuit board, it is necessary to measure multiple times and take the average value to obtain a relatively accurate value, and the measurement process is relatively cumbersome and takes a long time.

[0004] In daily work, during the process of the device detecting the circuit board, there is a problem that the existing device is difficult to quickly detect the cut circuit board, and it is necessary for the detection personnel to measure each circuit board one by one, resulting in low detection efficiency of the detection personnel for the circuit board. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the existing device is difficult to quickly detect the circuit board in the prior art, and a measurement device for printed circuit boards is proposed.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A measuring device for a printed circuit board, comprising a placement plate, a connection frame and a circuit board. The connection frame is fixedly connected to the upper surface of the placement plate. The circuit board is disposed on the upper surface of the placement plate. The lower surface of the placement plate is fixedly connected with support blocks. A detection device is arranged on the upper surface of the placement plate. The detection device includes a first measuring scale and a slider. The slider is slidably connected to the surface of the connection frame. The first measuring scale is fixedly connected to the upper surface of the placement plate. One end of the slider is fixedly connected with a pointer. The pointer is arranged on the surface of the first measuring scale. The end of the slider away from the pointer is fixedly connected with a pressing plate. The side surface of the pressing plate is fixedly connected with a second measuring scale.

[0007] Further, a plurality of equally spaced limiting grooves are formed on the surface of the connection frame. A groove is formed inside the slider. By providing the slider, the pointer and the baffle can be moved in the same position, reducing the situation that when the device is in use, it is difficult for the pointer and the baffle to move together, resulting in different values indicated by the pointer and the value measured by the baffle.

[0008] Further, a limiting ball is slidably connected to the inner wall of the groove. One end of the limiting ball is clamped inside the limiting groove. The limiting ball is provided to facilitate the limitation of the slider.

[0009] Further, one end of the limiting ball away from the limiting groove is fixedly connected with a first spring. The end of the first spring away from the limiting ball is fixedly connected with the inner wall of the groove. The first spring is provided to facilitate applying a reset elastic force to the limiting ball.

[0010] Further, a positioning device is arranged on the upper surface of the placement plate. The positioning device includes a positioning hole and a fixing block. The fixing block is fixedly connected to the upper surface of the placement plate. The positioning hole is formed on the surface of the circuit board. A moving block is slidably connected inside the fixing block. A chute is formed at the lower end of the moving block. By forming the positioning hole on the surface of the circuit board, the circuit board can be preliminarily positioned, reducing the situation that the circuit board is likely to move when the device detects the circuit board.

[0011] Further, a second spring is fixedly connected to the top of the chute. The end of the second spring away from the top of the chute is fixedly connected to the bottom of the fixing block. A connecting rod is fixedly connected to the side surface of the upper end of the moving block. The connecting rod is provided to facilitate the connection between the moving block and the positioning rod.

[0012] Further, one end of the connecting rod away from the moving block is fixedly connected with a positioning rod. The positioning rod is clamped inside the positioning hole. The positioning rod is provided to facilitate the positioning of the circuit board.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, by providing a detection device, when the device is in use, the user directly moves the slider. Then, when the slider moves, it drives the baffle and the limit ball inside the slider to move. Subsequently, the movement of the limit ball drives the displacement and deformation of the first spring to generate elastic force. By providing the detection device, the circuit board on the placement plate can be effectively detected, playing a role in quickly detecting the circuit board. When traditionally measuring a circuit board, workers need to hold a measuring ruler to detect each circuit board one by one, wasting time and energy and resulting in low work efficiency of the detection personnel. This improves the practicality of the device.

[0015] 2. In the present utility model, by providing a positioning device, when the device is in use, the user pulls the connecting rod. Then, when the connecting rod moves, it drives the positioning rod and the moving block to move together. When the positioning rod and the moving block move simultaneously, when the positioning rod moves out of the inside of the positioning hole, the moving block slides inside the fixed block to drive the displacement and deformation of the second spring to generate elastic force. Subsequently, when the positioning rod disengages from the positioning hole, the circuit board loses its restraint. By providing the positioning device, the circuit board can be effectively fixed, playing a role in quickly limiting and fixing the circuit board. It reduces the situation that when the device is in use, it is difficult for the circuit board to be combined inside the connection frame during detection, resulting in the device being difficult to accurately detect the circuit board. The positioning device can position the detected circuit board, improving the accuracy of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a measuring device for a printed circuit board, including a placement board 1, a connection frame 2 and a circuit board 3. The connection frame 2 is fixedly connected to the upper surface of the placement board 1. The circuit board 3 is arranged on the upper surface of the placement board 1. The lower surface of the placement board 1 is fixedly connected with a support block 4.

[0023] Next, specifically describe the specific settings and functions of its detection device 5 and positioning device 6.

[0024] In this implementation: a detection device 5 is arranged on the upper surface of the placement board 1. The detection device 5 includes a first measuring scale 51 and a slide block 52. The slide block 52 is slidably connected to the surface of the connection frame 2. The first measuring scale 51 is fixedly connected to the upper surface of the placement board 1. One end of the slide block 52 is fixedly connected with a pointer 53. The pointer 53 is arranged on the surface of the first measuring scale 51. One end of the slide block 52 away from the pointer 53 is fixedly connected with a contact plate 54. The side surface of the contact plate 54 is fixedly connected with a second measuring scale 55.

[0025] Specifically, a plurality of equally spaced limit grooves 56 are opened on the surface of the connection frame 2. A groove 57 is opened inside the slide block 52.

[0026] In this embodiment: by setting the slide block 52, the pointer 53 and the baffle can be moved in the same position, reducing the situation that when the device is in use, it is difficult for the pointer 53 and the baffle to move together, resulting in different values indicated by the pointer 53 and the value measured by the baffle.

[0027] Specifically, a limit ball 58 is slidably connected to the inner wall of the groove 57. One end of the limit ball 58 is clamped inside the limit groove 56. The limit ball 58 is provided to facilitate the limitation of the slide block 52.

[0028] Specifically, one end of the limit ball 58 away from the limit groove 56 is fixedly connected with a first spring 59. One end of the first spring 59 away from the limit ball 58 is fixedly connected with the inner wall of the groove 57. The first spring 59 is provided to facilitate applying a reset elastic force to the limit ball 58.

[0029] In this embodiment: a positioning device 6 is provided on the upper surface of the placement plate 1, and the positioning device 6 includes a positioning hole 61 and a fixed block 62. The fixed block 62 is fixedly connected to the upper surface of the placement plate 1, and the positioning hole 61 is opened on the surface of the circuit board 3. A moving block 63 is slidably connected inside the fixed block 62, and a sliding groove 66 is opened at the lower end of the moving block 63.

[0030] In this embodiment, by opening a positioning hole 61 on the surface of the circuit board 3 , the circuit board 3 can be initially positioned, thereby reducing the possibility that the circuit board 3 is easily moved when the device is testing the circuit board 3 .

[0031] Specifically, a second spring 67 is fixedly connected to the top of the slide groove 66, and one end of the second spring 67 away from the top of the slide groove 66 is fixedly connected to the bottom of the fixed block 62. The side surface of the upper end of the moving block 63 is fixedly connected to the connecting rod 64. The connecting rod 64 is provided to facilitate the connection between the moving block 63 and the positioning rod 65.

[0032] Specifically, one end of the connecting rod 64 away from the moving block 63 is fixedly connected with a positioning rod 65 , and the positioning rod 65 is engaged with the inside of the positioning hole 61 . The positioning rod 65 is provided to facilitate positioning of the circuit board 3 .

[0033] Working principle: When the equipment is in use, the user directly moves the slider 52, and then the movement of the slider 52 drives the baffle and the limiting ball 58 inside the slider 52 to move, and then the movement of the limiting ball 58 drives the first spring 59 to displace and deform to generate elastic force. By setting the detection device 5, the circuit board 3 on the surface of the placement plate 1 is effectively detected, which plays a role in quickly detecting the circuit board 3. When measuring the circuit board 3 in the traditional way, workers need to hold a measuring ruler to detect the circuit boards 3 one by one, which wastes time and energy, causes the work efficiency of the detection personnel to be low, and improves the practicality of the equipment.

[0034] When the device is in use, the user pulls the connecting rod 64, and the connecting rod 64 moves, driving the positioning rod 65 and the moving block 63 to move together. When the positioning rod 65 and the moving block 63 move at the same time, when the positioning rod 65 moves to the inside of the positioning hole 61, the moving block 63 slides inside the fixed block 62, driving the second spring 67 to displace and deform to generate elastic force. Then, when the positioning rod 65 is out of the positioning hole 61, the circuit board 3 loses its restraint. By setting the positioning device 6, the circuit board 3 is effectively fixed, which plays a role in quickly limiting and fixing the circuit board 3, reducing the situation in which the circuit board 3 is difficult to combine with the inside of the connecting frame 2 during detection when the device is in use, making it difficult for the device to accurately detect the circuit board 3. The positioning device 6 can position the detected circuit board 3, thereby improving the accuracy of the device.
