DETAILED DESCRIPTION

[0019] Example 1

[0020] like Figures 1 to 5As shown, the present invention discloses a line scan camera test platform, including a mounting plate 1, a support column 2, a slide 3, a slide rail 4, a side rotating seat 5, a side rotating plate 6, a mounting beam 7, a light stick block 8, a light stick 9, an adjustment slide 10, a rotating base 11, a material clamp 12, a slider 13, a slider connecting plate 14, a locking bolt 15, a side bracket base 16, a rotating shaft 17, a bracket connecting plate 18, a side bracket 19, a light source mounting seat 20, a light source 21, a camera mounting plate 22, an adjustment rod base 23, and an adjustment screw 2 4. Camera clamping plate 25; support columns 2 are installed at the four corners of the lower surface of the mounting plate 1, and a slide groove 3 is opened in the center; the slide rail 4 is installed on the upper surface of the mounting plate 1, located on the front and rear sides of the slide groove 3; the side rotating seat 5 is installed on the edge of the upper surface of the mounting plate 1, located on the front and rear sides of the slide rail 4; the side rotating plate 6 is installed on the side rotating seat 5; the two ends of the mounting beam 7 pass through the rotating plate 6 and are fixed with nuts, and a number of clamping holes are opened on all four sides; the light stick clamping block 8 is clamped into the clamping hole of the mounting beam 7; the light stick 9 is stuck on the light stick block 8; the adjusting slide 10 is installed on the slide slot 3; the rotating base 11 is installed in the center of the upper surface of the adjusting slide 10, and a telescopic rod is provided on it; the material clamp 12 is installed on the top of the telescopic rod; the slider 13 is installed on the slide rail 4; the slider connecting plate 14 is installed on the upper surface of the slider 13 and is fixed with a locking bolt 15; the side bracket base 16 is installed at both ends of the upper surface of the slider connecting plate 14; the rotating shaft 17 is installed on the side bracket base 16 and fixed with a nut; the bracket connecting plate 18 is installed on the rotating shaft 17; the side bracket 19 is installed at the end of the bracket connecting plate 18 and fixed with bolts; the light source mounting seat 20 is equipped with a shaft installed at the end of the side bracket 19, and light sources 21 are installed on both sides of it; the camera mounting plate 22 is installed in the center of the upper surface of the slider connecting plate 14; the adjusting rod base 23 is installed on the left and right edges of the camera mounting plate 22; the adjusting screw 24 is installed on the adjusting rod base 23, and a camera clamp 25 is installed at the end thereof. The length of the chute 3 is the same as that of the rail 4. The adjustment slide 10 can slide within the chute 3, and the rotating base 11 can rotate on the adjustment slide 10. The top telescopic rod is relatively fixed to the rotating base 11. When the telescopic rod is fully extended, its upper surface is flush with the camera mounting plate 22. When the telescopic rod on the rotating base 11 is retracted, it can slide from one side of the slider connecting plate 14 to the other side, allowing for arbitrary adjustment of the relative position of the line scan camera and the object to be inspected. The adjustment slide 10 is fixed by tightening bolts at the four corners, making installation and fixation simpler and more convenient. The rotating base 5 has a total of four parts, which are installed in two groups with left and right symmetry. The base is provided with a number of slots on the circumference of the base. Each rotation of the rotating shaft is locked into the slot. The side rotating base 5 rotates through an angle of 150 degrees. The side rotating plate 6 changes position as the side rotating base rotates. With the vertical direction as the center, it can rotate 75 degrees in each direction. During rotation, it is locked into the slot of the side rotating base 5 for every 5 degrees of rotation.The upper end of the side rotating plate 6 has a long mounting hole, which allows for the adjustment of the mounting position of the mounting beam 7, thereby assisting in changing the distance between the light bar mounted on the mounting beam 7 and the object being inspected. The bracket connecting plate 18 is fixed to the rotating shaft 17, which can rotate on the side bracket base 16. The side bracket 19 can rotate on the bracket connecting plate 18 and is locked with screws. The light source mounting bracket 20 can rotate along the side bracket 19 and self-lock. Power supply mounting brackets are installed on both sides of the bracket, facilitating the adjustment of the relative position of the light source 21 on both sides and the line scan camera, ensuring that the line scan camera is always under stable lighting, avoiding significant changes in the brightness near the line scan camera caused by the light bar 9 passing by, which would affect the image quality.

[0021] The working principle of the present invention is as follows: During use, the initial test position of the line scan camera is determined based on the test object. The relative position of the slide plate 10 and the slide connecting plate 14 is adjusted according to the direction of movement of the line scan camera. The position of the rotating base 11 and the telescopic rod thereon is then adjusted. The test object is clamped with the material clamp 12. The slider 13 is moved to its maximum distance to place the line scan camera on the camera mounting plate 22. The adjusting screw 24 is rotated to clamp the line scan camera through the camera clamp 25 and securely fixed with a nut. The two side rotating plates 6 are then adjusted in sequence, and the fixed height of the mounting beam 7 is adjusted so that the mounting beam 7 is on both sides of the test object. The light bar clamp 8 is then installed in the appropriate clamping hole according to the appearance of the test object, and the light bar 9 is clamped to the light bar clamp 8. Finally, the side bracket 19 and the light source mounting base 20 are adjusted to ensure that the light source 21 installed next to the line scan camera maintains an appropriate distance from the line scan camera to avoid obvious illumination when the line scan camera is close to the test object, which may affect the shooting effect. After installation is completed, the slider 13 can be controlled to move back and forth to take a photo test of the test object.

[0022] The present invention can freely adjust the fixed position of the inspection object as needed, thereby simulating the distance between the inspection object and the line scan camera under various sizes. At the same time, the angles of the two side rotating plates and the height of the mounting beam can be adjusted according to the position of the object, and a light stick of any length can be fixed at an appropriate position on the mounting beam according to the position relationship. At the same time, the position and height of the light source on both sides of the camera are adjusted by rotating the bracket connecting plate and the side bracket, so that the brightness difference near the lens of the line scan camera is smaller during movement, the shadow and reflection on the inspection object are reduced, and the shooting effect is improved.
