The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1-Figure 3 A camera lifting module shown in the figure comprises a fixed plate 1, which is a vertically mounted rectangular thick plate. Two vertically arranged guide rails 2 are symmetrically mounted on both sides of the front end surface of the fixed plate 1, and two sliders 21 are respectively mounted on each guide rail 2. The lifting plate 3 is movably mounted on the guide rail 2 through four sliders 21. A vertical mounting groove 11 is provided in the middle of the fixed plate 1, and a lifting drive member 4 is mounted in the mounting groove 11. Preferably, the lifting drive member 4 is a lead screw module, comprising a lead screw 41, and both ends of the lead screw 41 are respectively fixed in the mounting groove 11 through a bearing seat 42. A lead screw nut is screwed on the lead screw 41, and the lead screw nut is fixedly connected to the rear end surface of the lifting plate 3 through a nut seat 43. A servo motor 44 is fixed to the top of the fixed plate 1, and the top of the lead screw 41 is connected to the output shaft of the servo motor 44 through a coupling. The rotation of the servo motor 44 drives the lead screw 41 to rotate, and drives the lifting plate 3 to move up and down along the guide rail 2 through the lead screw nut.

[0024] like Figure 1 , Figure 3 As shown, a camera holder 5 is horizontally installed on the top of the front end surface of the lifting plate 3. The camera holder 5 is a rectangular plate. Two triangular support plates 51 are symmetrically fixed on both sides of the lower end surface of the camera holder 5. The two support plates 51 are respectively fixedly connected to the lifting plate 3 to improve the stability of the camera holder 5.

[0025] A mounting hole 52 is provided at the center of the camera bracket 5, an auxiliary bracket 53 is vertically mounted on the lower surface of the camera bracket 5, a fixing ring 54 is mounted on the lower end of the auxiliary bracket 53, and the fixing ring 54 is coaxially arranged with the mounting hole 52. During installation, the lens of the detection camera passes downward through the mounting hole 52 and is fixed on the camera bracket 5, and the auxiliary bracket 53 fixes the lens of the detection camera through the fixing ring 54 to prevent the detection camera from shaking during operation.

[0026] The fixing ring 54 is assembled from two semicircular arcs, one end of the two semicircular arcs is hinged, and the other end of the two semicircular arcs is locked by bolts to facilitate fixing the lens of the detection camera. An oblong slot is provided at the lower end of the auxiliary bracket 53, and the fixing ring 54 is fixedly connected to the auxiliary bracket 53 by bolts. The design of the oblong slot can adjust the height of the fixing ring 54 to adapt to detection cameras of different lengths.

[0027] like Figure 1 , Figure 2 As shown, a connecting pin 12 is horizontally installed on the side of the top of the fixed plate 1. A connecting seat 31 is fixed on the side of the lifting plate 3, and a tension spring 6 is installed between the connecting pin 12 and the connecting seat 31. The setting of the tension spring 6 can prevent the lifting plate 3 from moving down when the servo motor 44 is powered off, thereby ensuring the safety of the camera.

[0028] like Figure 2 As shown, a position sensor 131 is installed on the side of the fixed plate 1 through an L-shaped connecting piece 13, wherein the position sensor 131 is a photoelectric switch, and a trigger member 32 that cooperates with the position sensor 131 is fixed on the side of the lifting plate 3. The origin of the lifting plate 3 can be determined by the cooperation between the position sensor 131 and the trigger member 32, thereby realizing precise control of the lifting position of the camera bracket 5.

[0031] The working principle of embodiment 2 is:

[0032] When the product is inspected, the servo motor rotates forward to drive the inspection camera down to the appropriate inspection position, obtain the image of the product and transmit it to the computer for defect detection. After the inspection is completed, the servo motor reverses to drive the inspection camera back to the origin, and so on.

[0033] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0034] 1. By installing a tension spring between the fixed plate and the lifting plate, the detection camera can be prevented from sliding down due to its own weight when the power is off, thereby avoiding damage to the detection camera lens;
