[0095] The arrangement of the second slide rail 18 and the second slider 19 can further provide guidance for the sliding of the second limiting rod 3 relative to the second mounting plate 13 and also make the sliding of the second limiting rod 3 smoother.

[0096] In one embodiment, the second slide rail 18 and the second limiting rod 3 are respectively arranged on opposite sides of the second mounting plate 13 along the second direction x, so as to realize the installation of the second slide rail 18 and the second limiting rod 3 on the second mounting plate 13.

The guiding rods 51 extend along the first direction z and are connected between the first end plate 113 and the second end plate 114. The carrier plate 4 is slidably connected to the guiding rods 51 along the first direction z, and the guiding rods 51 can provide guidance for the carrier plate 4 along the first direction z.

[0103] In one embodiment, as Figures 1 to 6As shown, the frame 1 further includes a pallet 6 and a guide sleeve 7. The pallet 6 is arranged perpendicular to the first direction z. The guide sleeve 7 is installed on the pallet 6 and is slidably connected to the guide rod 51 along the first direction z. By the sliding of the guide sleeve 7 relative to the guide rod 51, the pallet 6 can be driven to move along the first direction z.

[0104] The carrier plate 4 is installed on the pallet 6 to realize the installation of the carrier plate 4.

[0107] The first end plate 113 includes a first sub - plate 1131 and a second sub - plate 1132.

The first limiting rod 2 abuts against one of the top corners of the material 8, and the second limiting rod 3 abuts against another top corner of the material 8. The top corner abutting against the first limiting rod 2 and the top corner abutting against the second limiting rod 3 are opposite along the diagonal of the material 8.

[0116] For the feeding device provided by the embodiment of the present utility model, first slide the first limiting rod 2 relative to the frame 1 along the second direction x, and slide the second limiting rod 3 relative to the frame 1 along the third direction y, so that the first limiting rod 2 and the second limiting rod 3 abut against the edge of the material 8 on the carrier plate 4, and limit the material 8 in the second direction x and the third direction y to prevent the material 8 from tilting and sliding. Then, drive the carrier plate 4 to slide relative to the guiding mechanism 5 along the first direction z through the lifting assembly, so as to drive the material 8 carried by the carrier plate 4 to move smoothly along the first direction z, reducing the risk of damaging the material 8.

[0117] In one embodiment, the lifting assembly includes a lifting cylinder. By connecting the piston rod of the lifting cylinder to the carrier plate 4, the lifting cylinder can drive the carrier plate 4 to slide relative to the guiding mechanism 5 along the first direction z.

[0118] Alternatively, the lifting assembly may also include a motor, a screw rod, and a nut. The screw rod extends along the first direction z. The output shaft of the motor is connected to the screw rod. The nut is threadedly connected to the screw rod and is connected to the carrier plate 4. The motor is used to drive the screw rod to rotate. When the motor drives the screw rod to rotate, the nut will move along the axial direction of the screw rod, thereby driving the carrier plate 4 to move along the first direction z.

[0119] In addition, an embodiment of the present utility model further provides a PCB board testing device, including a testing device, a marking device, and the above-mentioned feeding device. The feeding device, the testing device, and the marking device are arranged in sequence along the conveying direction of the material 8. The feeding device is used to provide the material 8 for the testing device. The testing device is used to test the material 8. The marking device is used to mark the material 8 that has completed the testing.

[0120] The material 8 is a PCB board.

[0121] The PCB board testing device according to the embodiment of the present utility model provides the material 8 for the testing device through the feeding device. The testing device tests the material 8, and the marking device marks the material 8 that has completed the test. Among them, the feeding device first slides the first limiting rod 2 relative to the frame 1 along the second direction x, and slides the second limiting rod 3 relative to the frame 1 along the third direction y, so that the first limiting rod 2 and the second limiting rod 3 abut against the edge of the material 8 on the carrier plate 4, and limit the material 8 in the second direction x and the third direction y to prevent the material 8 from tilting and sliding. After that, the lifting assembly is used to drive the carrier plate 4 to slide relative to the guiding mechanism 5 along the first direction z, so as to drive the material 8 carried by the carrier plate 4 to move smoothly along the first direction z, reducing the risk of damaging the material 8.

[0122] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
