[0024] Next, a pressing device in this exemplary embodiment will be further described.

[0025] In the embodiment of the present application, the pressing plate 20 and the top plate 30 are connected by a telescopic rod 40, the top plate 30 is in a fixed state, one end of the telescopic rod 40 is connected to the top plate 30, and the other end is connected to the pressing plate 20. When the pressing plate 20 moves up and down, the telescopic rod 40 can play a supporting and guiding role, and will not affect the movement of the pressing plate 20. The pressing plate 20 is slidably connected to the guide column 50 provided on the bottom plate 10, the bottom plate 10 is in a fixed state, the guide column 50 is fixed on the bottom plate 10, and the pressing plate 20 is slidably connected to the guide column 50 through a sliding bearing, so that the pressing plate 20 can move up and down along the guide column 50 to achieve the pressing action.

[0026] As an example, four telescopic rods 40 and four guide columns 50 are provided, and the four telescopic rods 40 are located at the top four corners of the pressing plate 20, and the four guide columns 50 are located at the top four corners of the bottom plate 10.

[0027] In the embodiment of the present application, the connecting rod driving mechanism is connected between the pressing plate 20 and the top plate 30, and the connecting rod driving mechanism includes a driving member 61, a rotating shaft 62 and at least one group of connecting rod units, wherein the driving member 61 is fixed to the top plate 30, the rotating shaft 62 is connected to the output end of the driving member 61, and the rotating shaft 62 is suspended below the top plate 30 through a fixing member 63; wherein the driving member 61 is a driving motor, and the output shaft of the driving motor is connected to the rotating shaft 62 through a coupling 68; one end of the connecting rod unit is connected to the rotating shaft 62, and the other end of the connecting rod unit is connected to the pressing plate 20. The driving member 61 drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives the connecting rod unit to swing, and the bottom of the connecting rod unit drives the pressing plate 20 to move up and down to achieve pressing and pressure release. By converting the circular swinging motion of the connecting rod unit into the up and down vertical motion of the pressing plate 20, the compression space between the pressing plate 20 and the bottom plate 10 can be greatly compressed, thereby improving the pressing efficiency and reducing the size of the device.

[0028] As an example, the connecting rod unit includes a first connecting rod 64 and a second connecting rod 65, one end of the first connecting rod 64 is fixedly connected to the rotating shaft 62, the other end of the first connecting rod 64 is hinged to one end of the second connecting rod 65, and the other end of the second connecting rod 65 is hinged to a connecting block 66 disposed on the top of the pressing plate 20. Through the above design, one end of the first connecting rod 64 rotates with the rotation of the rotating shaft 62, and the other end of the first connecting rod 64 swings in a circle within a larger radius, thereby driving the second connecting rod 65 to move upward or downward, and then driving the pressing plate 20 to move upward or downward through the second connecting rod 65.

[0029] As an example, the fixing member 63 is provided with a plurality of fixing members 63, each fixing member 63 is provided with a through hole, the rotating shaft 62 is passed through the through hole, and the rotating shaft 62 is connected to the through hole via a rolling bearing 67; one of the fixing members 63 is located at an end of the rotating shaft 62 away from the driving member 61.

The circumference of the fan-shaped piece 71 corresponds to the left and right swing circumference of the first connecting rod 64, and the fan-shaped piece 71 rotates with the rotation of the rotating shaft 62. During the rotation of the fan-shaped piece 71, when the photoelectric switch 72 continuously senses that the fan-shaped piece 71 passes through, the first connecting rod 64 swings upward in the left or right direction, and when the photoelectric switch 72 does not sense that the fan-shaped piece 71 passes through, the first connecting rod 64 is at the lowest point, and the pressing plate 20 is at the lowest position. By detecting the signal of the photoelectric switch 72, the rotation direction of the rotating shaft 62 can be controlled, thereby controlling the movement stroke of the pressing plate 20, and then controlling the pressing test strength of the electronic product.
