The base 101 is a fixed bracket of the whole focusing device, which ensures the stability of the whole focusing device. The base 101 is an elongated plate, and its upper surface is rectangular. The target plate 102 is disposed at one end of the base 101, and the target plate 102 is perpendicular to the base 101. The target plate 102 is rectangular. The scale 103 is provided on the target plate 102, and the position of the scale 103 can be fixed by the target plate 102. The scale 103 is located on a vertical side of the target plate 102, which may be mounted to the target plate 102 by way of a inlay. The scale 103 is mainly used for focusing of the industrial camera 104, thereby determining a focal length when the industrial camera 104 photographs the production device. The sliding table 108 is disposed on the base 101, and the sliding table 108 and the scale 103 are located on the same side of the target board. The micrometer 107 is mounted on one side of the sliding table 108, and its axis is perpendicular to the side face of the target plate 102 where the scale 103 is located. The camera mount 105 is provided on the upper surface of the slide table 108. The industrial camera 104 is mounted on a camera mount 105, and the lens of the industrial camera 104 faces the scale 103. The clamping pieces 106 are mounted on the upper surface of the camera mount 105, which are located on both sides of the housing of the industrial camera 104.
Fig. 2 and 3 show the structure of the slide table 108 in the focusing apparatus. The slide table 108 includes a slide table fixed block 202, a slide table slider 201, and an L-shaped top block 206. The sliding table fixed block 202 is fixedly mounted on the upper surface of the focusing device base 101 in a bolt manner, and a sliding rail 203 is arranged on the upper surface of the sliding table fixed block 202. The lower surface of the sliding table slide block 201 is sunken to form a groove, a sliding groove 207 is arranged in the groove, the sliding groove 207 is adaptive to the sliding rail 203, and the sliding table slide block 201 can be arranged on the sliding table fixed block 202 through the sliding groove 207 and the sliding rail 203, so that the sliding table slide block 201 can slide back and forth along the sliding rail 203. An L-shaped top block 206 is mounted on the side of the slide table slider 201 by means of bolts, which is mainly used to determine the moving distance of the micrometer 107.
As shown in fig. 2, 3 and 4, a micrometer support 205 is mounted on one side of the slide table fixing block 202 by a bolt method, and the micrometer 107 is mounted on the micrometer support 205 by a bolt method. When the micrometer 107 rotates to scale, the top 204 of the micrometer 107 can contact the L-shaped top block 206, and with further rotation of the micrometer 107, the micrometer 107 can push the L-shaped top block 206 to advance synchronously, so as to further push the sliding table slider 201 to advance synchronously.
Fig. 5 shows a state in which the industrial cameras are focused, the clamping pieces 106 are symmetrically disposed at both sides of the industrial adder housing, and the distance between the clamping pieces 106 can be adjusted by the waist-shaped holes 302 and the fixing screws, thereby fixing the industrial cameras of different specifications on the adder stand 105. When it is necessary to focus the industrial camera 104, the industrial camera 104 is placed on the camera mount 105, and then the distance between the industrial camera lens 301 and the scale 103 is roughly adjusted. After the distance between the two is preliminarily adjusted, the distance between the clamping pieces 106 is adjusted, and the industrial camera 104 is fixed on the camera bracket 105. In this state, the micrometer head 204 contacts the L-shaped slide table top block 206, but there is no pressing force therebetween.
As shown in fig. 6, a connection block 401 is provided between the camera mount 105 and the slide slider 201, the camera mount 105 is fixed on the connection block 401, and the connection block 401 is fixed on the slide slider 201, so that the camera mount 105 is fixed on the slide slider 201 through the connection block 401. The three can be connected by bolts. When the camera mount 105 is fixed on the slide slider 201, the camera mount 105 can be moved synchronously with the movement of the slide slider 201. After the distance between the industrial camera lens 301 and the scale 103 is primarily adjusted (see fig. 5), the rotating micrometer 107 and the micrometer plug 204 advance, so that the L-shaped sliding table top block 206 is extruded, the L-shaped sliding table top block 206 is pushed to move towards a direction close to the target plate, the sliding table sliding block 201 is further driven to move along the sliding rail 203 on the sliding table fixed block 202, and the camera support 105 and the industrial camera 104 also synchronously move towards a direction close to the target plate, so that the industrial camera lens 301 gradually approaches the scale 103. Since the precision of the micrometer 107 is 0.01mm, the industrial camera lens 301 can gradually move to a direction approaching the target plate with a precision of 0.01 mm. When the definition of the scales on the scale 103 meets the shooting requirement, the focus fixing screw of the industrial camera 104 can be locked, and the focusing process of the industrial camera is completed. And then the industrial camera is taken down from the focusing device, so that shooting operation of industrial equipment can be performed. The micrometer 107 is then reversed, and the micrometer 107 is reset. At this time, the micrometer head 204 is separated from the L-shaped sliding table top block 206, and then the sliding table slider 201 is gently pushed in a direction away from the target plate manually, and the sliding table slider 201 moves in a direction away from the target plate along the sliding rail 203, so that the L-shaped sliding table top block is finally restored to a state of being in contact with the micrometer head 204 but not being mutually extruded. When the industrial camera with another specification needs to be focused, repeating the operation.
It should be noted that, the sliding table 108 in the present utility model may be replaced by a rack-and-pinion structure or a belt pulley structure, and the feeding distance of the sliding table is determined by the rotation angle of the gear or the rotation angle of the belt pulley, so as to adjust the distance between the industrial camera and the target board.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the content of the present utility model or direct or indirect application in other related technical fields are included in the scope of the present utility model.
