Description

Technical Field

[0001] The utility model relates to the technical field of pressing plate devices, in particular to a rotary pressing plate device. Background Art

[0002] The function test principle of the washing machine controller is to connect the input and output ends of the circuit board. After supplying power to the input end, each function module on the circuit board is tested. For example, it is tested whether the output voltages of the communication interface, analog switch, and other washing machine load ports are normal, etc.

[0003] The currently commonly used low-cost test solution is to connect the controller with the input end and the output end through elastic metal thimbles, and at the same time, adopt the method of manually pressing the controller. The controller is limited above the elastic metal thimble through a positioning clip to conduct a function test on the controller. There are the following problems with such a manually pressed test method:

[0004] (1) The labor intensity of manual pressing operation is large: After statistics, employees have to repeat pressing thousands of controllers every day, and the labor intensity of employees is large, which does not conform to the concept of lean production.

[0005] (2) The positioning of the controller is inaccurate: When manually pressing the controller, it may occur that the pressing is off-position, resulting in ineffective contact between the controller and the metal test probe, affecting the product quality.

[0006] (3) The controller is under excessive force: When manually pressing the controller, it may occur that the force is too large during pressing, and the controller is under excessive stress, resulting in the failure of the controller and affecting the product quality.

[0007] (4) The production test efficiency is low: Due to the limitation of manual operation, only one controller can be manually pressed each time during the production test process. There is a situation where the first pressing is not in place and needs to be repeated, resulting in low test efficiency and increased test costs.

[0008] In the prior art, there are already automated function test devices, but the existing test devices are relatively complex and large in volume, and are not suitable for large-scale application on the production line of washing machine controllers. Therefore, a rotary pressing plate device is needed that can automatically position the workpiece to be detected, such as a washing machine controller, replace manual pressing, improve the test efficiency, and reduce the test cost. Summary of the Utility Model

[0054] Embodiment 3

[0055] As Figures 1-4As shown in the figure, this embodiment provides a rotary pressing plate device, which includes a rotating part connected with a pressing part. The rotating part can drive the pressing part to rotate. A bearing part is arranged below the pressing part, and a workpiece to be detected is arranged on the bearing part. A limiting part 4 is arranged close to the bearing part. The pressing part is used to press the workpiece to be detected to a preset position, and the limiting part 4 is used to limit the descending position of the workpiece to be detected during the pressing process.

[0056] The limiting part 4 includes a spring 41, and the spring 41 is located below the bearing part.

[0057] The fixed end of the spring 41 is arranged on the base 2, and the movable end of the spring 41 abuts against the bearing part.

[0058] The limiting part 4 further includes a positioning clamp 42. The positioning clamp 42 is arranged on the side of the bearing part. The positioning clamp 42 is adapted to the pressing plate 3 and is used to clamp the pressing plate 3.

[0059] Generally, there is 1 or N workpieces to be detected. Here, the workpiece to be detected is taken as an example of a washing machine controller. The size and shape of the washing machine controller are not limited. The size and shape of the bearing part can be adjusted to adapt to multiple washing machine controllers, which has a certain flexibility and meets different production requirements. When preparing to test the washing machine controller, first, multiple washing machine controllers need to be placed above the bearing part, and the bearing part and multiple washing machine controllers can be mutually adapted. At this time, the rotating part drives the pressing part to press downward. During the downward pressing process of the pressing part, the spring 41 below the bearing part is compressed. Until the pressing part presses multiple washing machine controllers downward to the preset position, one side of the pressing part can be clamped and fixed by the positioning clamp 42 of the limiting part 4. The tray 5 has a hollow structure. The test probe passes through the test hole of the tray 5 and then inserts into the test port of the workpiece to be detected to test the power module, load module and other modules of the controller.

[0060] The shape of the positioning clamp 42 can be U-shaped. The opening of the positioning clamp 42 faces the bearing part. A protrusion is arranged on the side of the pressing plate 3. During the downward movement of the pressing plate 3, the protrusion of the pressing plate 3 inserts into the opening of the positioning clamp 42, and the positioning clamp 42 limits the pressing plate 3. The protrusion on the side of the pressing plate 3 and the opening of the positioning clamp 42 are in interference fit. The protrusion squeezes the upper part of the opening of the positioning clamp 42, and the positioning clamp 42 exerts a downward force on the pressing plate 3. The bearing part exerts an upward force on the pressing plate 3. At this time, the pressing plate 3 is in a force balance state, and the workpiece to be detected reaches the preset position. The U-shaped positioning clamp 42 has a certain elasticity, and the pressing plate 3 can be clamped into the opening of the U-shaped positioning clamp 42 when moving downward.

[0061] The shape of the positioning clip 42 can also be T-shaped. The first part of the positioning clip 42 is horizontally arranged, and the second part of the positioning clip 42 is perpendicular to the first part of the positioning clip 42. During the downward movement of the pressing plate 3, the pressing plate 3 is caught between the lower side of the first part of the positioning clip 42 and the second part of the positioning clip 42. The pressing plate 3 squeezes the positioning clip 42 upward. The first part of the positioning clip 42 exerts a downward force on the pressing plate 3, and the bearing part exerts an upward force on the pressing plate 3. At this time, the pressing plate 3 and the workpiece to be detected are in a force balance state, and the workpiece to be detected reaches the preset position.

[0062] When the pressing part is not in contact with the workpiece to be detected, the elastic force corresponding to the deformation of the spring 41 is equal to the sum of the gravity of the workpiece to be detected and the bearing part. When the pressing part presses the workpiece to be detected downward, the workpiece to be detected and the bearing part move downward, and the compression amount of the spring 41 increases until the workpiece to be detected reaches the preset position.

[0063] This embodiment provides a rotary pressing plate device. By placing a plurality of workpieces to be detected above the bearing part, the pressing part presses the workpiece to be detected above the bearing part downward through the rotating part until the workpiece to be detected reaches the preset position. The positioning clip 42 of the limiting part 4 clamps and fixes one side of the pressing part. At this time, the movable end of the spring 41 below the bearing part is compressed, and the spring 41 exerts an upward force on the bearing part, while the positioning clip 42 exerts a downward force on the pressing part. The pressing part exerts a downward force on the workpiece to be detected, and the bearing part exerts an upward force on the workpiece to be detected, so that the workpiece to be detected is in a force balance state. When the pressing part is pressed, the edge part of the workpiece to be detected is stressed as a whole. Compared with the traditional manual pressing, this device can effectively reduce the pressing stress on the workpiece to be detected during testing.

[0078] A positioning post 6 is arranged on the base 2, and the bearing part includes a notch 7, and the notch 7 is adapted to the positioning post 6.

[0079] A test switch 8 and a test lamp 9 are arranged on the base 2.

[0080] By placing multiple workpieces to be detected above the tray 5 of the bearing part, and then pressing the pressing part downward through the rotating part, the workpiece to be detected and the bearing part move downward. The test probe below the bearing part passes through the test hole of the tray 5 and then inserts into the test port of the workpiece to be detected, starting the test process. Press the test switch 8 on the base 2, and the test lamp 9 lights up green, indicating that the workpiece to be detected is being tested. After testing for a period of time, if the test lamp 9 turns yellow, it means that the test process has been completed and the workpiece to be detected is normal. If during the test process, the test lamp 9 suddenly turns red and flashes continuously, it means that there is a problem with the test process and the workpiece to be detected does not meet the requirements. At this time, the pause switch can be pressed to pause the test. A reset button can also be set on the base 2. When a problem occurs at the start of the test or during the test process, the reset button can be pressed to reset the pressing part and the bearing part. After the operator eliminates the fault, the next test can be carried out on the workpiece to be detected.

[0081] In the base of this embodiment, a test switch and a test lamp are provided. Press the test switch 8 on the base 2, and the test lamp 9 lights up green, indicating that the workpiece to be detected is being tested. After testing for a period of time, if the test lamp 9 turns yellow, it means that the test process has been completed and the workpiece to be detected is normal. If during the test process, the test lamp 9 suddenly turns red and flashes continuously, it means that there is a problem with the test process and the workpiece to be detected does not meet the requirements. At this time, the pause switch can be pressed to pause the test.

[0082] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present application. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0083] It should be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures of the device. For example, if the device in the figures is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will then be positioned "below other devices or structures" or "beneath other devices or structures". Thus, the exemplary term "above..." can include both the orientation of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatially relative descriptions used here.

[0084] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above terms have no special meaning, so it should not be construed as a limitation on the scope of protection of this application.
