Description

Technical Field

[0001] This utility model relates to the field of medical device testing, specifically to a PCB board knob testing device for an electronic acupuncture therapy instrument. Background Technology

[0002] Among currently available medical devices, one category involves control knobs, which users rotate to control functions. For example... Figure 1 As shown, taking the electronic acupuncture therapy device 1 as an example, the electronic acupuncture therapy device 1 includes several operating knobs 2 for controlling the output current intensity. When using it, the user can change the current intensity by rotating the operating knobs 2, thereby achieving the desired electroacupuncture therapy intensity and effect.

[0003] The above-mentioned electronic acupuncture therapy devices have the following deficiencies at the manufacturing level:

[0004] 1. The lifespan of knobs varies between different batches, and the lifespan information of the knobs cannot be effectively grasped, which will affect the use effect for customers and pose a risk of customer complaints.

[0005] Second, the current method for testing the lifespan of a knob is to manually rotate the knob repeatedly and manually determine whether it has reached its lifespan limit by monitoring the output voltage of the knob (if a break point occurs, the voltage will drop to 0 or be significantly lower than the set standard voltage). This method is not only time-consuming and laborious, and can easily cause personnel fatigue, but also cannot accurately measure the break point of the knob, resulting in poor reliability of the test results.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0010] The platform is also provided with a vertically set frame, on which a second positioning seat is connected. The second positioning seat is provided with several test modules. Each test module includes a motor and a rotary drive unit controlled by the motor. Each rotary drive unit corresponds one-to-one with the first rotation axis of each knob on the PCB board under test and is connected in transmission.

[0011] It also includes a control center, which is located in the host and is electrically connected to each of the knobs under test on the PCB board under test, and electrically connected to the motors in each of the test modules.

[0012] In the above scheme, the PCB board to be tested is assembled inside the housing of the electronic acupuncture therapy device.

[0013] In a further technical solution, the rotation drive unit is a second rotation shaft; the second rotation shaft is coaxially aligned with the first rotation shaft in the vertical direction; the two rotation shafts are connected by a plug-in structure, the plug-in structure includes a plug and a slot, one of the plug and the slot is located at the head of the first rotation shaft, and the other is located at the head of the second rotation shaft.

[0015] In a further technical solution, the motor of the test module is a first motor; the lifting mechanism includes a second motor and a lifting plate; the second motor is fixed to the upper end of the frame, and the lifting plate is directly or indirectly driven by the second motor to slide in the up and down direction relative to the frame; the second positioning seat is connected to the front side of the lifting plate.

[0016] A further technical solution also includes a connecting plate and a spring. The connecting plate is slidably disposed on the front side of the frame in the vertical direction, and the output shaft of the second motor is connected to the lifting plate in a transmission manner. The lifting plate is slidably disposed on the front side of the connecting plate in the vertical direction. The spring is vertically disposed and acts between the connecting plate and the lifting plate.

[0022] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0023] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0026] During testing, the PCB board under test is first clamped on the first positioning seat, and the PCB board under test is connected to the host to ensure that the circuits corresponding to each knob are electrically connected to the control center. Then, the rotation drive unit of each test module is connected to the first rotation axis of each knob, and the rotation drive unit is driven to rotate by starting the motor, which in turn drives the first rotation axis of the knob to rotate, realizing the simulation of human hand operation of the knob by rotating the motor. When the knob is rotated multiple times until a break occurs, the sharp drop in voltage will send a trigger signal to the control center. The control center will issue a prompt or record and display the corresponding information (such as: which knob has broken, how many times the knob was rotated when the break occurred), and at the same time shut down the motor of the corresponding test module.

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0042] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0043] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0044] See appendix Figures 1-8 As shown, an electronic acupuncture therapy instrument PCB board knob testing device includes a main unit 3, which has an upper platform 4. A first positioning seat 6 for clamping a PCB board 5 to be tested is horizontally fixed on the platform 4. The PCB board 5 to be tested includes a plurality of spaced-apart knobs 7 to be tested, and each knob 7 has a first rotation axis 8.

[0045] The platform 4 is also provided with a vertically arranged frame 9, and a second positioning seat 10 is connected to the frame 9. The second positioning seat 10 is provided with several test modules 11. Each test module 11 includes a motor and a rotary drive unit controlled by the motor. Each rotary drive unit corresponds one-to-one with and is connected to the first rotation axis 8 of each knob 7 on the PCB board under test 5.

[0046] It also includes a control center, which is located in the host 3 and is electrically connected to each of the test knobs 7 on the PCB board 5 and to the motors in each of the test modules 11.

[0047] Preferred, such as Figure 3 , Figure 5 As shown, the rotation drive unit is a second rotating shaft 12; the second rotating shaft 12 is coaxially aligned with the first rotating shaft 8 in the vertical direction; the two rotating shafts are connected by a plug-in structure, the plug-in structure includes a plug 13 and a slot 14, one of the plug 13 and the slot 14 is located at the head of the first rotating shaft 8, and the other is located at the head of the second rotating shaft 12.

[0048] Preferably, it also includes a lifting mechanism for driving the second positioning seat 10 to rise and fall, the lifting mechanism being disposed on the frame 9.

[0049] Preferably, the motor of the test module 11 is a first motor 15; the lifting mechanism includes a second motor 16 and a lifting plate 17; the second motor 16 is fixed to the upper end of the frame 9, and the lifting plate 17 is directly or indirectly driven by the second motor 16 to slide in the up and down direction relative to the frame 9.

[0050] The second positioning seat 10 is fixed to the front side of the lifting plate 17.

[0051] Preferably, it also includes a connecting plate 18 and a spring 19. The connecting plate 18 is slidably disposed on the front side of the frame 9 in the vertical direction. The output shaft of the second motor 16 is connected to the lifting plate 17 through a lead screw (not shown in the figure). The lifting plate 17 is slidably disposed on the front side of the connecting plate 18 through a guide post 24 in the vertical direction.

[0052] The spring 19 is vertically positioned and acts between the connecting plate 18 and the lifting plate 17. When the second motor 16 operates, it first drives the connecting plate 18 and the lifting plate 17 to move downwards as a whole, thereby moving the second positioning seat 10 downwards. When the test module 11 on the second positioning seat 10 aligns with the knob 7 to be tested on the first positioning seat 6, the lifting plate 17 can maintain a stable downward pressure due to the action of the spring 19, thus ensuring that the plug 13 on the second rotating shaft 12 and the slot on the first rotating shaft 8 maintain a stable plug-in connection.

[0053] Preferably, it also includes two position sensors 20, which are respectively set to the upper limit position and the lower limit position of the second positioning seat 10, and both position sensors 20 are electrically connected to the control center.

[0054] Preferably, each of the test modules 11 is slidably mounted in the second positioning seat 10 via a horizontal slide rail 21, making the horizontal position of each test module 11 adjustable. This adapts to the knob 7 spacing of different PCB boards 5 under test, improving the versatility of the testing device.

[0055] The host unit 3 is also equipped with a display screen 22, and the output of the control center is electrically connected to the display screen 22. The host unit 3 is also equipped with several buttons 23, which are used to control the power on / off of the host unit 3 and the start / stop of the motor.

[0056] The working principle of this utility model is explained as follows:

[0057] During testing, the PCB board 5 to be tested is first clamped on the first positioning seat 6, and the PCB board 5 to be tested is connected to the host 3 so that the circuits corresponding to each of the knobs 7 are electrically connected to the control center.

[0058] Then, adjust the horizontal position of each test module 11 on the second positioning seat 10 so that the second rotation axis 12 of each test module 11 is coaxially aligned with the first rotation axis 8 of each knob 7 on the PCB board under test in the vertical direction. Then control the second positioning seat 10 to descend so that the first rotation axis 8 and the second rotation axis 12 are connected by plug 13 and slot 14.

[0059] Next, each first motor 15 is started to drive each second rotating shaft 12 to rotate, which in turn drives each first rotating shaft 8 to rotate, thus simulating the operation of the knob 7 by a human hand through the rotation of the motor.

[0060] The control center can be a PLC. When the knob 7 is rotated multiple times until a break occurs, the circuit corresponding to the knob 7 is disconnected, causing a rapid drop in voltage, which is sent to the PLC as a trigger signal. At this time, the PLC can control the buzzer to emit a prompt sound or display the corresponding information (such as: which knob 7 broke, how many times the knob 7 was rotated when the break occurred) on the display screen 22, and at the same time shut down the first motor of the corresponding test module 11.

[0061] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
