[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The present embodiment provides a technical solution: a double probe device with a cam linkage mechanism, comprising a fixed plate 1, a connecting rod 4 is vertically penetrated on the fixed plate 1, a No. 1 bearing 11 is arranged on a side surface of the upper end of the connecting rod 4, a sliding block 7 is arranged on the lower end of the connecting rod 4, a guide rail 6 is arranged at the center of the upper side surface of the sliding block 7, a cam disc 3 is arranged on the side of the No. 1 bearing 11 away from the connecting rod 4, a cam groove 12 is arranged on the side of the cam disc 3 facing the connecting rod 4, a limiting arc groove 13 is arranged on the lower side of the cam groove 12, an arc plate 15 is arranged on the upper outer ring side of the cam disc 3, and a sensor 8 is arranged on the upper side of the arc plate 15.

[0020] like Figure 1-3 As shown, the sensor 8 can detect the distance between the cam discs 3. When the arc plate 15 on the cam disc 3 rotates to the lower side of the sensor 8, the sensor 8 detects a signal. When the sensor 8 detects the end of the arc plate 15, the sensor 8 sends a signal to the motor 2, causing the motor 2 to rotate in the opposite direction, thereby causing the cam disc 3 to rotate in the opposite direction. The protrusion in the cam groove 12 can lift the No. 1 bearing 11, thereby driving the connecting rod 4 to move laterally, so that the probe module 10 at the lower end of the connecting rod 4 performs pin insertion detection on the electronic device. After the cam disc 3 rotates one hundred and eighty degrees, the sensor 8 can detect the signal of the cam disc 3 again, thereby causing the motor 2 to rotate in the opposite direction again, thereby causing the connecting rod 4 to drive the probe module 10 to detach from the electronic device.

[0021] A support plate 5 is disposed on a side of the connecting rod 4 away from the cam disc 3 , and a motor 2 is disposed on a side of the support plate 5 away from the cam disc 3 .

[0022] like Figure 1-3 As shown, the support plate 5 can support and fix the motor 2, and the motor 2 provides power for the rotation of the cam plate 3.

[0023] A No. 2 bearing 14 is arranged in the limiting arc groove 13 , and a limiting rod 9 is arranged on one side of the No. 2 bearing 14 .

[0024] like Figure 1-3 As shown, the second bearing 14 can be connected to the limiting rod 9, and the second bearing 14 moves in the limiting arc groove 13, thereby limiting the rotation of the cam plate 3 to prevent the rotation angle of the cam plate 3 from exceeding the range.

[0025] A probe module 10 is disposed on the opposite side of the sliding block 7 , and the probe module 10 is connected to the sliding block 7 by bolts.

[0026] like Figure 1-3 As shown, the probe module 10 can insert a probe into an electronic device to test the electronic device.

[0027] The support plate 5 is connected to the fixing plate 1 by bolts, and the fixing plate 1 is connected to the guide rail 6 by bolts.

[0028] like Figure 1-3 As shown, the fixing plate 1 can support and fix the supporting plate 5 , thereby fixing the motor 2 , and can also support and fix the guide rail 6 .

[0029] The sliding block 7 is slidably connected to the guide rail 6 , and the connecting rod 4 is connected to the cam plate 3 via a No. 1 bearing 11 .

[0030] like Figure 1-3 As shown, the sliding block 7 can move along the guide rail 6, thereby driving the measuring probe module 10 to move.

[0031] The limiting rod 9 is connected to the limiting arc groove 13 via a No. 2 bearing 14 .

[0032] The working principle of a double-probe device with a cam linkage mechanism provided by the utility model is as follows: Figure 1-Figure 3 As shown, when in use, the electronic device to be tested is placed between the two measuring probe modules 10, and the motor 2 drives the cam plate 3 to rotate, so that the No. 1 bearing 11 rolls along the outer ring side of the cam groove 12. When rolling to the raised structure in the cam groove 12, the No. 1 bearing 11 drives the connecting rod 4 to move laterally, so that the sliding block 7 on the lower side of the connecting rod 4 moves laterally along the guide rail 6, so that the measuring probe module 10 is inserted into the electronic device for testing. After the test, the sensor 8 can detect the signal of the cam plate 3 rotating one hundred and eighty degrees, and then send a signal to the motor 2, so that the motor 2 rotates in the opposite direction. After the reverse rotation, the No. 1 bearing 11 in the cam groove 12 drives the connecting rod 4 to move in the opposite direction, so that the measuring probe module 10 at the lower end of the connecting rod 4 is unplugged from the electronic device, thereby improving the testing efficiency of the device.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
