[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] In the embodiment, given by Figure 1 There is provided a conveying circuit board mechanism of a detector, including a body 1, including a detection piece 13, and a moving mechanism 2 disposed inside the body 1 for conveying a circuit board;

[0025] A sealing mechanism 3 disposed on the moving mechanism 2, the sealing mechanism 3 including a transparent glass cover plate 33, and a fastening mechanism 4 for fixing the circuit board;

[0026] An installation groove 12 is provided on the body 1, and the moving mechanism 2 is disposed inside the installation groove 12;

[0027] The cover plate 33 is provided with tempered glass 331 and a dimension bar 332; the tempered glass 331 is disposed inside the cover plate 33; the dimension bar 332 is disposed on the cover plate 33;

[0028] The moving mechanism 2 includes a mounting plate 21 disposed inside the installation groove 12; a connecting plate 22 disposed inside the installation groove 12; a servo motor 23 disposed on the mounting plate 21; a lead screw 24 disposed at the output end of the servo motor 23; two guide shafts 25 symmetrically disposed between the mounting plate 21 and the connecting plate 22 along the lead screw 24; a carrier table 26 disposed outside the lead screw 24 and sliding between the two guide shafts 25.

[0029] In this embodiment, a conveying circuit board mechanism of a detector of the present utility model is provided. The circuit board is placed on the upper surface of the moving mechanism 2, and then the cover plate 33 is attached to the upper surface of the moving mechanism 2 so that the cover plate 33 covers the surface of the circuit board. Then, the sealing mechanism 3 and the machine body 1 are fixed by the fastening mechanism 4 to prevent dust from falling onto the circuit board during the detection process. Then, the circuit board is transported to the detection part 13 by the moving mechanism 2 for detection, thereby improving the detection effect of the circuit board. The detection part 13 takes pictures of the circuit board through the tempered glass 331 on the cover plate 33, and the size bar 332 can be used to measure the size specifications of the circuit board when taking pictures for detection.

[0030] More preferably, as Figure 1 shown, there are two bellows protective covers 14 provided inside the installation groove 12, and the other ends of the two bellows protective covers 14 are respectively provided on the bearing table 26.

[0031] In this embodiment, multiple specific preferred embodiments of the moving mechanism 2 are given. The circuit board is placed in the placement groove opened on the bearing table 26, and the servo motor 23 drives the lead screw 24 to rotate. Since the bearing table 26 is also located outside the two guide shafts 25 and slides, the rotating lead screw 24 will drive the bearing table 26 to move, thereby moving the circuit board to the detection position. At the same time, when the bearing table 26 moves, the bellows protective cover 14 will be stretched by the bearing table 26, thereby ensuring that the moving mechanism 2 can always be dust-proof.

[0032] Preferably, as Figure 3 shown, the sealing mechanism 3 further includes two electric push rods 31, which are symmetrically arranged on both sides of the bearing table 26 in the front and back; two connecting pieces 32 are respectively arranged at the output ends of the two electric push rods 31.

[0033] More preferably, the two connecting pieces 32 are respectively rotatably arranged on the cover plate 33 and are symmetrically distributed in the front and back.

[0034] In this embodiment, multiple specific preferred embodiments of the sealing mechanism 3 are given. The electric push rod 31 drives the connecting piece 32 to move. Since the connecting piece 32 is rotatably arranged on the cover plate 33 and the electric push rod 31 is rotatably arranged on the bearing table 26, when the electric push rod 31 drives the connecting piece 32 to move, it will drive the cover plate 33 and the bearing table 26 to fit together, so that the cover plate 33 can fit on the surface of the bearing table 26 to cover the circuit board and prevent dust from falling onto the circuit board during the detection process.

[0035] Preferably, as Figure 4As shown, the fastening mechanism 4 includes: a support plate 41 provided outside the carrier 26; an AC motor 42 provided on the support plate 41, and the output end of the AC motor 42 is connected to a cylinder 43; a fastening plate 44 provided at the output end of the cylinder 43.

[0036] More preferably, as Figure 1 shown, the number of the fastening mechanisms 4 is four, and two of the fastening mechanisms 4 are in a group and are respectively provided on both sides of the carrier 26.

[0037] In this embodiment, multiple specific preferred embodiments of the moving mechanism 2 are given. The cylinder 43 is driven to rotate by the AC motor 42, so that the fastening plate 44 at the output end of the cylinder 43 is located on the cover plate 33. The cylinder 43 drives the fastening plate 44 to move downward, so that the fastening plate 44 presses the cover plate 33 downward, making the cover plate 33 and the carrier 26 fit tightly together, thereby improving the sealing performance between the cover plate 33 and the carrier 26. Furthermore, it is ensured that when the circuit board is moving for detection, it will not be affected by dust and other sundries, and the detection effect of the circuit board is better.
