Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Please see Figures 1 to 6 This invention relates to a portable circuit board function testing device, which includes a function testing component 10, a clamping component 20 installed on top of the function testing component 10, and an identification component 30 installed on one side of the clamping component 20.

[0030] The functional testing component 10 includes a base 11, a test circuit module (not shown) installed inside the base 11, a carrier plate 12 installed on the top surface of the base 11, two fixtures 13 installed side-by-side on the top surface of the carrier plate 12, and multiple spring test probes 14 respectively installed at one end of each fixture 13. The spring test probes 14 pass downward through the carrier plate 12 and enter the interior of the base 11 to connect with the test circuit module. The fixtures 13 are used to position and clamp the circuit board 40 under test, and the spring test probes 14 are used to abut against the circuit board 40 under test. When the fixtures 13 are not clamping the circuit board 40 under test, the tip of the spring test probe 14 slightly protrudes beyond the top surface of the fixture 13.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, multiple pads 41 are distributed on the bottom surface of one end of the circuit board under test 40. The spring test probe 14 abuts against the pads 41 one by one to realize the electrical connection between the circuit board under test 40 and the test circuit module, so as to facilitate the functional testing.

[0032] Furthermore, a serial number label 42 is affixed to the top surface of one end of the circuit board 40 under test. The serial number label 42 is used to identify the corresponding component 30.

[0033] Please refer to it again. Figure 3 In this embodiment, the end of the fixture 13 away from the spring test probe 14 is provided with a through hole 131; the functional detection component 10 also includes two photoelectric sensors 15 mounted side by side inside the carrier plate 12, with each photoelectric sensor 15 corresponding to a fixture 13. Specifically, the photoelectric sensor 15 passes through the through hole 131 and then moves upward to detect whether the circuit board 40 under test is properly clamped.

[0034] In this embodiment, positioning holes 132 are provided at the four opposite corners of the top surface of the fixture 13, and the positioning holes 132 are used to match the clamping assembly 20.

[0035] The clamping assembly 20 includes a first bracket 21 located on one side of the carrier plate 12, a push-pull cylinder 22 installed at the middle of the top of the first bracket 21, a lifting plate 23 connected to the end of the push-pull cylinder 22, two supports 24 installed side by side on the bottom surface of the lifting plate 23, pressure plates 25 respectively installed on the bottom surface of each support 24, and a plurality of spring plungers 26 respectively elastically installed on the bottom surface of each support 24; the spring plungers 26 pass through and protrude beyond the bottom surface of the pressure plate 25.

[0036] The pressure plate 25 is positioned above the fixture 13. The portion of the spring plunger 26 extending beyond the pressure plate 25 is used to elastically abut against the circuit board 40 under test. The spring plunger 26 is used to press the circuit board 40 under test tightly against the spring test probe 14, ensuring electrical connection between the circuit board 40 under test and the test circuit module, and preventing poor contact that could lead to testing errors.

[0037] In this embodiment, the clamping assembly 20 also includes positioning pins 27 respectively installed on opposite sides of the bottom surface of each support 24. The positioning pins 27 correspond one-to-one with the positioning holes 132 to ensure the alignment accuracy of the support 24 and the fixture 13, thereby ensuring that the spring plunger 26 effectively abuts against the circuit board 40 to be tested.

[0038] The identification component 30 includes a second bracket 31 mounted on the top surface of the carrier plate 12, and two scanners 32 rotatably mounted on opposite sides of the top of the second bracket 31. The scanners 32 are electrically connected to the test circuit module. The scanners 32 face downwards toward the serial number tag 42 and are used to read the serial number of the circuit board under test 40. This enables automatic identification and data binding, ensuring that the test result of each circuit board under test 40 is associated with the unique serial number in real time, avoiding human error and improving efficiency. After the serial number identification is completed, the push-pull cylinder 22 is activated to drive the pressure plate 25 and the spring plunger 26 to press down the circuit board under test 40.

[0039] In this embodiment, in order to improve the stability of the movement of the lifting plate 23, the opposite sides of the lifting plate 23 are respectively slidably connected to the inner wall of the second bracket 31 through the guide rail pair 230.

[0040] The aforementioned portable circuit board functional testing device has a simple structure and is easy to use. The scanner 32 reads the serial number of the circuit board 40 under test. The push-pull cylinder 22 drives the pressure plate 25 and the spring plunger 26 to press down the circuit board 40 under test. The circuit board 40 under test is in close contact with the spring test probe 14 to perform functional testing. It can realize automatic identification and data binding, ensuring that the test result of each circuit board 40 under test is associated with the unique serial number in real time, avoiding human error and improving efficiency.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
