[0044] As described in the background section, the stability of the circuit board, a key component of the endoscope, directly affects the product's production efficiency and quality. However, from procurement to assembly, the circuit board undergoes processes such as storage, repackaging, and transportation. If the circuit board is damaged during these processes, it is generally not visible to the naked eye. It can only be detected after being assembled with other components into a finished product and undergoing product testing. Furthermore, connecting with other components may induce other malfunctions, leading to low testing efficiency, inaccurate test results, and increased production costs.

[0045] Based on this, please refer to Figures 1-5 This utility model provides an endoscope circuit board testing device 100 and equipment, which can effectively improve the aforementioned technical problems. Specifically, it can quickly test the quality of the circuit board before endoscope assembly, saving testing time, and can detect fault areas on the circuit board, improving testing efficiency and accuracy, while reducing costs. The endoscope circuit board testing device 100 and equipment will be described in detail below.

[0046] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the endoscope circuit board testing device 1000 provided in this embodiment, combined with... Figure 1 The endoscope circuit board testing equipment 1000 includes an endoscope circuit board testing device 100, a camera device 200, and an image processing device 300, both of which are electrically connected to the endoscope circuit board testing device 100.

[0047] It should be noted that the endoscope circuit board testing device 100 can test the circuit board to determine whether the circuit board is of good quality; the camera device 200 is an image capturing device that mimics the tip of the endoscope, and can transmit the signal captured or recorded during the test to the image processing device 300 through the endoscope circuit board testing device 100; the image processing device 300 is used to process the captured or recorded signal and then generate an image, thereby determining whether the image measured by the tip of the endoscope and the image effect after being processed by the circuit board meet the requirements.

[0048] Please refer to Figure 2 , Figure 2 This is a structural schematic diagram of the endoscope circuit board testing device 100 provided in this embodiment from a first-view perspective, combined with... Figure 2 The endoscope circuit board testing device 100 includes a test chamber 10, a probe assembly 30, a current and voltage testing module 40, and a functional testing module 50. The test chamber 10 has a tray 20 for mounting the circuit board. The probe assembly 30 is used to contact the circuit board. The current and voltage testing module 40 is located in the test chamber 10 and electrically connected to the probe assembly 30. The functional testing module 50 is located in the test chamber 10 and electrically connected to the probe assembly 30. Figure 1 and Figure 2 Specifically, both the camera device 200 and the image processing device 300 are electrically connected to the probe assembly 30.

[0049] During circuit board testing, the circuit board is placed on tray 20, and the circuit is established by the probe assembly 30 contacting the circuit board. Then, the current and voltage testing module 40 monitors the current and voltage of the circuit board in real time. Simultaneously, the functional testing module 50 simulates the state of the circuit board when connected to the product for use, testing whether all functions are correct. In other words, this endoscope circuit board testing device 100 can directly test the circuit board before endoscope assembly, quickly determining whether there are missing, incorrect, or defective components, saving testing time. It can also identify faulty areas on the circuit board based on different modules, thereby improving testing efficiency and accuracy, and reducing costs.

[0050] Specifically, the current and voltage testing module 40 includes an ammeter 42 and a voltmeter 43, both of which are electrically connected to the probe assembly 30. As is easily understood, the ammeter 42 monitors and displays the operating current of the circuit board, while the voltmeter 43 monitors and displays the voltage of the circuit board, thus facilitating real-time observation of current and voltage changes by the operator.

[0051] Since there are many voltage points on the circuit board, in order to monitor and display the various voltages on the circuit board more comprehensively, the number of voltmeters 43 can be set to multiple. The probe assembly 30 includes a current probe and multiple voltage probes (not shown in the figure). The multiple voltage probes are electrically connected to multiple voltmeters 43 respectively, and the current probes are electrically connected to ammeters 42. In order to facilitate the reasonable installation and arrangement of ammeters 42 and voltmeters 43, the current and voltage test module 40 also includes a mounting box 41. The mounting box 41 is set in the test box 10, and both ammeters 42 and voltmeters 43 are set in the mounting box 41.

[0052] It should be noted that in this embodiment, there is one ammeter 42 and nine voltmeters 43, which are used to display the input voltage, output LED voltage, output CLK voltage, output sensor voltage, and four circuit board voltage points, respectively. Of course, in other embodiments, the number of voltmeters 43 can be other numbers, which need to be determined according to the specific design of the circuit board and the actual test requirements.

[0053] Please continue to combine Figure 2 Specifically, in this embodiment, the functional testing module 50 includes a screen function button 51, a photo / video recording function button 52, a freeze function button 53, and a reserved function button 54. Correspondingly, the probe component 30 includes a screen probe, a photo / video recording probe, a freeze probe, and a reserved probe. The screen function button 51, the photo / video recording function button 52, the freeze function button 53, and the reserved function button 54 are electrically connected to the screen probe, the photo / video recording probe, the freeze probe, and the reserved probe, respectively.

[0054] Understandably, by operating the screen function button 51, the photo / video function button 52, and the freeze function button 53, the button operations of the endoscope can be simulated, that is, the screen function, photo / video function, and freeze function can be tested to ensure they are working correctly. The reserved function button 54 is provided to facilitate testing when other functions are added to the endoscope in the future, thereby improving versatility and adaptability, further increasing testing efficiency and reducing costs.

[0055] It should be noted that in some other embodiments, the functional test module 50 may also include one or more of the following: screen function button 51, photo and video recording function button 52, freeze function button 53, and reserved function button 54. The specific type of function button setting needs to be determined according to the actual design requirements.

[0056] Please refer to Figure 3 and Figure 4 , Figure 3 This is a partially exploded view of the endoscope circuit board testing device 100 provided in this embodiment. Figure 4 This is a structural schematic diagram of the tray 20 provided in this embodiment, combined with... Figures 2-4 The probe assembly 30 includes a probe holder 31, a first probe unit 32, and a second probe unit 33. The probe holder 31 is spaced apart from the tray 20. The first probe unit 32 is located on the side of the probe holder 31 near the tray 20. A through hole 21 is provided on the tray 20. The second probe unit 33 is located in the test chamber 10 and is used to extend out of the through hole 21 to contact the bottom of the circuit board. The endoscope circuit board testing device 100 also includes a drive assembly 60, which is located in the test chamber 10 and connected to the probe holder 31. The drive assembly 60 is used to drive the probe holder 31 to move so that the first probe unit 32 contacts the top of the circuit board. The first probe unit 32 is electrically connected to the current and voltage testing module 40 and / or to the functional testing module 50. The second probe unit 33 is electrically connected to the current and voltage testing module 40 and / or to the functional testing module 50.

[0057] By setting the first probe unit 32 and the second probe unit 33, contact tests can be performed on opposite sides of the circuit board, thereby more comprehensively testing different points on the circuit board and further improving testing efficiency. At the same time, the fault areas of the circuit board can be further subdivided, thereby improving the accuracy of the test results.

[0058] It should be noted that both the first probe unit 32 and the second probe unit 33 include multiple probes, which can be current probes, voltage probes, screen probes, image / video recording probes, freeze probes, and reserved probes mentioned above. It is readily understood that in some embodiments, at least some probes in the first probe unit 32 can be electrically connected to the current / voltage testing module 40 or the functional testing module 50; similarly, at least some probes in the second probe unit 33 can also be electrically connected to the current / voltage testing module 40 or the functional testing module 50. The specific number of probes electrically connected to the current / voltage testing module 40 or the functional testing module 50 needs to be determined based on the testing requirements and the circuit board design.

[0059] Specifically, the drive assembly 60 includes a bracket 61 and a drive component 62. The bracket 61 is disposed on the test chamber 10, and the drive component 62 is disposed on the bracket 61 and connected to the probe holder 31. It should be noted that in this embodiment, the drive component 62 is specifically a push-pull quick clamp. Of course, in other embodiments, the drive component 62 can also be an electric push rod, a hydraulic cylinder, or an oil cylinder, etc.

[0060] Please continue to combine Figures 2-4Furthermore, the tray 20 and the test chamber 10 are spaced apart. The endoscope circuit board testing device 100 also includes an elastic element 71, which is disposed between the tray 20 and the test chamber 10 and is connected to both the tray 20 and the test chamber 10. When the first probe unit 32 contacts the top of the circuit board, the drive assembly 60 is also used to drive the tray 20 toward the test chamber 10 via the first probe unit 32 and the circuit board and / or via the probe seat 31, so that the second probe unit 33 extends out of the through hole 21 and contacts the bottom of the circuit board.

[0061] In other words, during the process of the drive assembly 60 driving the probe holder 31 to move towards the test chamber 10, the first probe unit 32 will contact the top of the circuit board. At this time, the drive assembly 60 will continue to drive the probe holder 31 to move downward. Thus, the pressure between the first probe unit 32 and the circuit board will be applied to the tray 20, and / or after the first probe unit 32 contacts the top of the circuit board, the probe holder 31 can contact and drive the tray 20 to continue moving downward, thereby causing the tray 20 to move towards the test chamber 10. In this way, the second probe unit 33 will extend from the through hole 21 and then contact the bottom of the circuit board. By setting the elastic element 71, a buffering effect can be provided for the tray 20, preventing the tray 20 from moving too fast and causing damage to the second probe unit 33 and the circuit board. Furthermore, when the circuit board is not being tested, the tray 20 can return to its initial state under the elastic force of the elastic element 71, thereby hiding the second elastic unit under the tray 20 and providing a certain degree of protection for the second elastic unit.

[0062] It should be noted that the elastic element 71 can be a spring, a sheet, or a rubber sleeve, or other elastic structures. In addition, in this embodiment, there are four elastic elements 71. Of course, in other embodiments, the number of elastic elements 71 can be one, two, or three, etc.

[0063] To further improve the stability of the tray 20 during movement and enhance testing accuracy, in this embodiment, the test chamber 10 is provided with a guide hole 11, and the endoscope circuit board testing device 100 also includes a guide post 72. The guide post 72 is disposed on the side of the tray 20 near the test chamber 10, and the guide post 72 is movably disposed in the guide hole 11.

[0064] It should be noted that in this embodiment, there are two guide posts 72 and two guide holes 11. Of course, in other embodiments, there may be one, three or four guide posts 72 and two guide holes 11, etc.

[0065] Please continue to combine Figure 4To facilitate circuit board installation, the tray 20 is also provided with a mounting slot 22. The bottom wall of the mounting slot 22 has a through hole 21, and the mounting slot 22 is used to mount the circuit board. It is easy to understand that by providing the mounting slot 22, the installation stability of the circuit board can be improved, ensuring stability during subsequent contact testing with the probes, reducing shaking, and thus further improving the accuracy of the test results.

[0066] After the test is completed, in order to facilitate the removal of the circuit board from the mounting slot 22, in this embodiment, the tray 20 is also provided with a notch 23, which is connected to the mounting slot 22.

[0067] Please refer to Figure 5 , Figure 5 This is a structural schematic diagram of the endoscope circuit board testing device 100 provided in this embodiment from a second perspective, combined with... Figure 5 The endoscope circuit board testing device 100 also includes a signal transmission interface 81, which is located in the test chamber 10 and electrically connected to the probe assembly 30.

[0068] Combination Figure 1 and Figure 5 The signal transmission interface 81 can be electrically connected to the image processing device 300, thereby transmitting the signals during the test to the image processing device 300 for corresponding processing. It should be noted that the signal transmission interface 81 can also be connected to an external power supply to power the circuit board during the test.

[0069] Furthermore, the endoscope circuit board testing device 100 also includes a power interface 82, which is located in the test housing 10 and electrically connected to the current and voltage testing module 40. That is, an external power supply can be connected through the power interface 82 to power the voltmeter 43 and the ammeter 42 in the current and voltage testing module 40, ensuring their normal operation.

[0070] In addition, the endoscope circuit board testing device 100 also includes a power switch 83, which is located in the test chamber 10. As can be easily understood, the power switch 83 can control the opening and closing of the power supply during the test.

[0071] In summary, the embodiments of this utility model provide an endoscope circuit board testing device 100 and equipment. The endoscope circuit board testing device 100 includes a test chamber 10, a probe assembly 30, a current and voltage testing module 40, and a functional testing module 50. A tray 20 is provided on the test chamber 10 for mounting the circuit board. The probe assembly 30 is used to contact the circuit board. The current and voltage testing module 40 is disposed in the test chamber 10 and electrically connected to the probe assembly 30. The functional testing module 50 is disposed in the test chamber 10 and electrically connected to the probe assembly 30. During circuit board testing, the circuit board is placed on the tray 20, and the circuit is established by the probe assembly 30 contacting the circuit board. Then, the current and voltage testing module 40 is used to monitor the current and voltage of the circuit board in real time. Simultaneously, the functional testing module 50 is used to simulate the state of the circuit board when connected to a product for use, in order to test whether the various functions are correct.

[0072] In other words, the endoscope circuit board testing device 100 can directly test the circuit board before the endoscope is assembled, quickly determine whether there are quality abnormalities such as missing, wrong, or defective components on the circuit board, save testing time, and can detect the fault area of ​​the circuit board according to different modules, thereby improving testing efficiency and accuracy and reducing costs.
