[0026] In this embodiment, the camera assembly 500 is a structure for performing shooting visual inspection and longitudinally adjusting the inspection range.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, the camera assembly 500 includes two mounting blocks 501 and two L-shaped plates 502, the left and right sides of the L-shaped plates 502 are fixedly connected with square blocks 503, the bottom of the mounting block 501 is fixedly connected with two slide bars 504, the bottom ends of the two corresponding slide bars 504 are fixedly connected with a limit plate 505, the bottom of the mounting block 501 is rotatably connected with a screw rod 506 through a bearing, the bottom end of the screw rod 506 is fixedly connected with an anti-slip plate 507, the outer side of the screw rod 506 is fixedly connected with a worm gear 508, and the mounting block 501 is fixedly connected with the outer side of the screw rod 506. The bottom of the L-shaped plate 502 is fixedly connected to a protection box 509 located on the outside of the corresponding worm gear 508, the inner side of the protection box 509 is rotatably connected to a worm 510 that meshes with the outer side of the corresponding worm gear 508 through a bearing, one front end of the worm 510 passes through the front of the corresponding protection box 509 and is fixedly connected to a handle 511, the top of the L-shaped plate 502 is connected to a camera body 512 through screws, an annular fill light 513 is slidably installed on the outer side of the camera body 512, and a laser rangefinder 514 is detachably connected to the right side of the L-shaped plate 502.

[0028] It should be noted that the top of the left square block 503 is provided with two through holes for the corresponding two sliding rods 504 to slide, so that the left square block 503 can slide between the outer sides of the corresponding two sliding rods 504, thereby limiting the L-shaped plate 502 through the left square block 503, and the top of the right square block 503 is provided with a lifting threaded hole for the corresponding screw rod 506 to be threadedly connected, so that the right square block 503 can be lifted and lowered under the rotation of the screw rod 506, and the top and bottom of the protective box 509 are provided with connecting holes for the corresponding screw rod 506 to pass through, so that the screw rod 506 can work normally.

[0029] In addition, two L-shaped plates 502 are respectively located at the bottom of the two mounting blocks 501. The L-shaped plates 502 are composed of a horizontal plate and a vertical plate fixedly connected at the bottom of the horizontal plate. The camera body 512 is located at the bottom of the horizontal plate, so that the camera body 512 can be easily installed without blocking the shooting path of the camera body 512. The circuit board to be inspected moves at the bottom of the camera body 512. By shooting with the camera body 512 and transmitting relevant data to a computer or other processing equipment, the circuit board can be inspected against each other, thereby realizing the function of visual inspection.

[0030] At the same time, the annular fill light 513 is connected to the left side of the vertical plate by screws, which is convenient for disassembly and assembly of the annular fill light 513. The annular fill light 513 is semicircular, which is convenient for removal from the outside of the camera body 512. The bottom end of the laser rangefinder 514 and the bottom end of the corresponding camera body 512 are located on the same horizontal plane, so that the value measured by the laser rangefinder 514 is the distance of the lens of the camera body 512 from the ground, which is convenient for the operator to judge.

[0031] In this embodiment, the horizontal adjustment component 400 is a structure for adjusting the lateral range of front, back, left, and right.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the horizontal adjustment component 400 includes a main drive box 401 fixedly connected to the bottom of the connecting plate 3, a double-threaded rod 402 is rotatably connected between the front and rear inner walls of the main drive box 401 through a bearing, two positioning light rods 403 are fixedly connected between the front and rear inner walls of the main drive box 401, two sliding blocks 404 are threadedly connected to the outer sides of the double-threaded rod 402, a sub-drive box 405 is fixedly connected to the bottom of the sliding block 404, a one-way screw 406 is rotatably connected between the left and right inner walls of the sub-drive box 405 through a bearing, a limiting light rod 407 is fixedly connected between the left and right inner walls of the sub-drive box 405, and a hand wheel 408 is fixedly connected to the left end of the one-way screw 406 and the front end of the double-threaded rod 402.

[0033] It should be noted that the two positioning light rods 403 are symmetrically distributed on the left and right, and the front end of the positioning light rod 403 passes through the two sliding blocks 404 in sequence, so that the sliding block 404 can slide stably on the outside of the two positioning light rods 403. At the same time, the positioning light rod 403 can also limit the sliding block 404. The bottom of the main drive box 401 and the bottom of the auxiliary drive box 405 are both opened, so that the sliding block 404 and the mounting block 501 can move normally.

[0034] In addition, the two sliding blocks 404 are symmetrically distributed front to back, and the front and back sides of the outer side of the double-threaded rod 402 are both threaded, and the thread directions are opposite. Therefore, when the double-threaded rod 402 rotates, the threads on both sides with opposite thread directions will respectively drive the two sliding blocks 404 to move closer to or away from each other.

[0035] At the same time, the right end of the limiting light rod 407 passes through the left side of the corresponding mounting block 501, and the left side of the mounting block 501 is provided with an internal threaded hole for threaded connection of the corresponding one-way screw 406, so that the mounting block 501 can move under the limiting action of the limiting light rod 407 and the threaded rotation thrust of the one-way screw 406, the left end of the one-way screw 406 passes through the left side of the corresponding auxiliary drive box 405, and the front end of the double-threaded rod 402 passes through the front of the main drive box 401, so that the three hand wheels 408 can be respectively located on the outside of the main drive box 401 and the auxiliary drive box 405, which is convenient for the operator to operate. In actual application, the hand wheel 408 can be replaced by a servo motor, and the handle 511 can be replaced by a small servo motor to achieve the purpose of automated operation and improve the overall degree of automation.

[0036] The working principle of the above embodiment is:

[0037] When visually inspecting the circuit board printed by the inkjet circuit board printer, the top hand wheel 408 is turned to rotate the double-threaded rod 402. Under the limiting action of the two positioning light rods 403, the two sliding blocks 404 can move closer to or away from each other, so as to adjust the distance between the two camera bodies 512. The bottom hand wheel 408 is turned to rotate the one-way screw rod 406. Under the limiting action of the limiting light rod 407, the mounting block 501 can be moved left and right for adjustment, thereby expanding the inspection range. The annular fill light 513 is started to illuminate the surface of the circuit board, which is beneficial to the shooting work of the camera body 512. When the height of the camera body 512 needs to be adjusted, the handle 511 is turned to rotate the worm 510, which drives the worm wheel 508 to rotate, and the lead screw 506 to rotate. Under the limiting action of the two corresponding slide bars 504, the L-shaped plate 502 can carry the camera body 512 and the laser rangefinder 514 for lifting and lowering adjustment. Under the cooperation of the worm 510 and the worm wheel 508, a self-locking function can be achieved when the rotation stops, thereby improving the stability of the camera body 512. At the same time, under the action of the laser rangefinder 514, the current height can be accurately displayed, which is convenient for the normal adjustment work, thereby further improving the range of visual detection.

[0038] Compared with the prior art, the visual inspection device of the inkjet circuit board printer can more conveniently adjust the camera height through the coordinated use of the connecting plate 3 at the bottom of the fixed plate 2, the horizontal adjustment component 400 and the camera component 500. It can not only normally meet the lateral adjustment requirements of the camera, but also can easily operate when the visual inspection height needs to be adjusted, making the overall operation process very convenient. At the same time, it can also judge the current height more accurately, thereby effectively improving the practicality of the visual inspection device of the inkjet circuit board printer and solving the problem that the visual inspection device of the existing inkjet circuit board printer is very inconvenient when adjusting the camera height.

[0039] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0040] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
