[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] An embodiment of the present application provides a main control board production and testing fixture for performing performance testing on a main control board of a clothes drying machine. The production and testing fixture comprises: a testing mechanism 20 and a fixing mechanism 10. The fixing mechanism 10 is fixedly connected to the testing mechanism 20 and is used to fix the main control board on the testing mechanism 20 for testing.

[0031] The test mechanism 20 is provided with an electric box 21, a test bench 22 and a plurality of detection structures. The electric box 21 is provided with a plurality of ejector contacts, and a plurality of detection structures are integrated on the electric box 21. The test bench 22 is provided above the electric box 21 to support the main control board. The fixing mechanism 10 is provided with a pressing plate 13, which is provided above the test bench 22 and is used to press the main control board toward the electric box 21 to contact the ejector contacts to achieve current or signal conduction.

[0032] The main control board production test fixture provided in the embodiment of the present application simplifies the operation process for operators by integrating power input, performance testing, etc.; avoids operators from manually plugging in high-voltage power supplies, thereby improving the safety of the production test process.

[0033] Furthermore, the main control board production and testing fixture is also provided with a trigger structure 30, which includes a trigger switch 31 and a pressure block 32 arranged relatively, one of which is arranged on the pressure plate 13, and the other is arranged on the electric box 21. In the process of fixing the main control board with the pressure plate 13, the pressure block 32 and the trigger switch 31 are in contact, and the pressure block 32 triggers the trigger switch 31 to supply power to the main control board. It is understandable that since the contacts of the electric box 21 are charged for a long time, the main control board is likely to cause arc ignition when contacting the contacts, which poses a great safety hazard. In the embodiment of the present application, only the electrical box 21 and the main control board are connected, and the main control board is not powered directly. Instead, a trigger structure 30 is provided to automatically control the stroke, and the main control board is powered on only after the trigger switch 31 is touched, thereby improving the safety performance of the production and testing fixture; and by respectively arranging the two mutually contacting parts of the trigger structure 30 on the pressure plate 13 and the electrical box 21, when the pressure plate 13 presses the main control board, the trigger switch 31 and the pressure block 32 are simultaneously touched, and the trigger structure 30 is triggered to power the main control board, and there is no need for the operator to additionally operate the trigger switch 31, thereby simplifying the operating steps.

[0034] Specifically, in some embodiments, the trigger switch 31 is disposed on the electrical box 21, and the pressure block 32 is disposed on the pressure plate 13, so that the wiring of the trigger switch 31 is facilitated. Furthermore, a plurality of support columns 131 are disposed on the side of the pressure plate 13 facing the test bench 22 to prevent the pressure plate 13 from squeezing the electronic components on the main control board and causing damage to the main control board.

[0035] Furthermore, in some embodiments, the end surface of the test bench 22 facing the pressure plate 13 is provided with a receiving groove 221, and the main control board is embedded in the receiving groove 221 for limiting. A plurality of positioning columns can also be provided in the receiving groove 221 to position the main control board and prevent the main control board from moving out of position.

[0036] Furthermore, in some embodiments, a reset structure 223 is provided at the bottom of the test bench 22, and the reset structure 223 is provided between the test bench 22 and the electric box 21, and is used to reset the test bench 22 after the test is completed, thereby disconnecting the connection between the main control board and the electric box 21. At the same time, the reset structure 223 can also buffer the impact of the pressure plate 13 on the main control board. It can be understood that the reset structure 223 can be an elastic reset structure, a damping reset structure, or a reset structure based on gear transmission, which will not be described in detail here.

[0037] Furthermore, in some embodiments, the fixing mechanism 10 is further provided with a pressing structure 11 and a supporting structure 12. The supporting structure 12 is fixedly connected to the electric box 21, the fixed end of the pressing structure 11 is fixedly connected to the supporting structure 12, and the movable end thereof is connected to the pressing plate 13 to drive the pressing plate 13 to move.

[0038] Specifically, the support structure 12 includes a support frame 121 and a first support plate 122. The support frame 121 is vertically fixed to the electric box 21, and the pressing structure 11 is fixed to the support frame 121 through the first support plate 122. It can be understood that the pressing structure 11 can be a quick clamp structure, and the operator manually presses the quick clamp structure to press the pressing plate 13 toward the electric box 21 until the pressing block 32 hits the trigger switch 31 to power the main control board. The pressing structure 11 can also be a second linear module controlled by a motor. The motor drives the pressing plate 13 to press toward the electric box 21 until the pressing block 32 presses the trigger switch 31 to power the main control board, and feeds back the power supply signal to the motor, and the second linear module stops moving; after the test is completed, the motor controls the second linear module to drive the pressing plate 13 to move away from the electric box 21 to perform the next cycle test.

[0039] As an example, in the embodiment of the present application, the pressing structure 11 is a quick clamp structure, including: a handle 111, a fixed seat 112 and a slide bar 113; the pressing plate 13 is fixedly connected to the end of the slide bar 113. Specifically, the fixed seat 112 is fixedly connected to the support frame 121 through the first support plate 122, the handle 111 is hinged to one end of the fixed seat 112, the slide bar 113 is slidably connected to the other end of the fixed seat 112, and the slide bar 113 is connected to the handle 111. The handle 111 drives the slide bar 113 to slide, so as to drive the movement of the pressing plate 13.

[0040] Furthermore, in some embodiments, the fixing mechanism 10 is also provided with at least one guide column 14, one end of the guide column 14 is fixedly connected to the support frame 121, and the other end is fixedly connected to the electrical box 21. The pressing plate 13 is sleeved on the middle part of the guide column 14 and performs reciprocating linear motion along the guide column 14 to ensure the stability of the operation of the pressing plate 13 and avoid the support column 131 from being offset and squeezing the electronic components due to the tilt of the pressing plate 13.

[0041] Furthermore, in some embodiments, the detection structure includes a first detection structure 23, which is used to detect the upper limit control function of the main control board. The first detection structure 23 includes an upper limit switch 231 and a first ejector pin, which are arranged on the electrical box 21 and are connected to each other. The upper limit switch 231 is arranged on the top or side wall of the electrical box 21 to facilitate continuous pressing by the operator. The first ejector pin is arranged below the test bench 22. The test bench 22 is provided with an ejector pin hole 222 corresponding to the first ejector pin. The first ejector pin passes through the ejector pin hole 222 and is connected to the main control board to realize the transmission of the upper limit signal and complete the detection of the upper limit control function of the main control board.

[0042] It is understandable that in the performance test of the clothes drying machine, the upper limit control test is very necessary. When the clothes drying rod rises to the limit position, it contacts the upper limit switch 231 provided on the clothes drying machine main unit to brake the clothes drying rod. In the traditional production test process, a micro switch is usually connected to the upper limit emergency stop terminal seat, and then the upper limit signal is input repeatedly for testing. This production test method requires frequent connection of the terminal seat, and the testing process is cumbersome. However, by integrating the first detection structure 23 into the electrical box 21, the embodiment of the present application does not require frequent plugging of the terminal seat, and the operation is simple and convenient.

[0043] Furthermore, in some embodiments, the detection structure also includes a second detection structure 25, which is used to detect the lighting control function of the main control board. The second detection structure 25 includes an indicator light 251 and a second ejector pin which are arranged on the electrical box 21 and are interconnected. The indicator light 251 is used to realize the visual output of the lighting function test. The second ejector pin is arranged below the test bench 22. The test bench 22 is provided with an ejector pin hole 222 corresponding to the position of the second ejector pin. The second ejector pin passes through the ejector pin hole 222 and is connected to the main control board to realize the transmission of the lighting signal and complete the detection of the lighting control function of the main control board. The second detection structure 25 is integrated into the electrical box 21, and the detection can be completed by contacting the second ejector pin contact, which can simplify the operation process of the operator; at the same time, the test results are output by whether the indicator light 251 is on or not, which is convenient for the operator to intuitively observe the test results and realize the visualization of the test results.

[0044] Furthermore, in some embodiments, the second detection structure 25 also includes a voltage regulating switch 252 connected to the main control board to adjust the test voltage, so as to adapt to products with various lighting voltages and improve the applicability of the production test fixture. Correspondingly, different indicator lights 251 are set for different lighting voltages, and the indicator lights 251 can be used to determine whether the test voltage matches.

[0045] As an example, in this embodiment, the electric box 21 is provided with two lighting voltages of DC 20V and DC 48V, and the voltage regulating switch 252 is a rocker switch provided on the electric box 21, which is used for switching between the two voltages. At the same time, the electric box 21 is provided with a first indicator light 251 corresponding to the DC 20V output, and a second indicator light 251 corresponding to the DC 48V output, so that the operator can visually observe the test results and judge whether they are consistent with the nominal value of the main control board.

[0046] Furthermore, in some embodiments, the detection structure also includes a third detection structure 24, which is used to detect the lifting control function of the main control board. The third detection structure 24 includes a bidirectional motion component and a third ejector pin that are arranged on the electrical box 21 and are interconnected. The bidirectional motion component is used to intuitively reflect the state of the clothes drying rod rising or falling through the forward or reverse motion of the bidirectional motion component to output the lifting test result. Similarly, the third ejector pin is arranged below the test bench 22, and the test bench 22 has an ejector pin hole 222 corresponding to the position of the third ejector pin. The third ejector pin passes through the ejector pin hole 222 and is connected to the main control board to realize the transmission of the lifting motion signal and complete the detection of the lifting control function of the main control board.

[0047] Specifically, in some embodiments, the bidirectional motion component is a first linear module 241, and the first linear module 241 is provided with a first driving member and a visual slider 242. The first driving member is arranged inside the electric box 21 and is connected to the third ejector signal. During the test, the main control board transmits the rising signal to the first driving member through the third ejector, and the first driving member rotates forward to drive the visual slider 242 to slide forward; the main control board transmits the descending signal to the first driving member through the third ejector, and the first driving member rotates reversely to drive the visual slider 242 to slide reversely. The operator can intuitively judge the detection result of the lifting control of the main control board by observing the sliding direction and sliding response of the visual slider 242. In this embodiment, the first linear module 241 is a screw module controlled by a micro motor, the micro motor is arranged inside the electric box 21, and the screw module is arranged on the electric box 21. It can be understood that the first linear module 241 can also be a linear guide module such as a cylinder module, or a module structure that can realize linear reciprocating motion such as a ball screw module, but it is not limited to this.

[0048] Specifically, in some other embodiments, the bidirectional motion component may also be a bidirectional fan, which is disposed outside the electrical box and is connected to the third ejector pin. During the test, the main control board transmits the lifting signal to the bidirectional fan through the third ejector pin, and the bidirectional fan rotates forward or reversely according to the lifting signal. The operator can visually judge the result of the lifting control detection of the main control board by observing the rotation direction of the bidirectional fan.

[0049] Compared with the prior art, the main control board production test fixture provided by the embodiment of the present application has the following beneficial effects:

[0050] (1) By integrating power input and performance testing, the operation process of operators is simplified; and by integrating automatic power stroke control and using a mechanical switch to trigger the fixture to turn the main control board on and off, the safety and stability of the production test process are further improved;

[0051] (2) By setting both lighting control detection and lifting control detection as visual output, it is convenient for operators to observe the test results;

[0052] (3) By setting multiple test voltages for the second detection structure, it can adapt to products with various lighting voltages, thereby improving the applicability of the production test fixture; at the same time, multiple indicator lights are set corresponding to different test voltages to facilitate observation of test results.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
