[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-5 This is the first embodiment of the present utility model, which provides a product visual inspection device, including a worktable 1, a horizontal linear guide rail 2 fixedly installed on one side of the top of the worktable 1, a vertical linear guide rail 3 fixedly installed on the top of the slider of the horizontal linear guide rail 2, a camera 5 provided on one side of the slider of the vertical linear guide rail 3, and the worktable 1 includes a rotating mechanism 6 for rotating the product and a clamping mechanism 8 for clamping the product.

[0025] A rotating cylinder 64 is rotatably connected to one end of the workbench 1. A turntable 65 is fixedly sleeved at the top of the rotating cylinder 64. Several second rubber pads 7 are fixedly connected to the top of the turntable 65. An electric push rod 81 is fixedly installed on the inner wall of the rotating cylinder 64. A top plate 82 is fixedly connected to the output shaft of the electric push rod 81. A fixed seat 83 is fixedly connected to the top of the top plate 82. Several linkage rods 84 are movably connected inside the fixed seat 83. One end of the linkage rod 84 is movably connected to the inner wall of the connecting seat 85. A clamping rod 86 is fixedly connected to the top of the connecting seat 85. The top of the clamping rod 86 passes through the inner wall of the turntable 65 and extends above it. A limit slider 87 is fixedly sleeved on the outer surface of the clamping rod 86. The outer surface of the limit slider 87 is slidably connected to the inner wall of the limit groove 88.

[0026] A motor 61 is installed at the bottom of the workbench 1. A gear 62 is fixedly sleeved on the output shaft of the motor 61. A gear ring 63 is meshed on the outer surface of the gear 62 and fixedly sleeved on the bottom surface of the rotating drum 64.

[0027] During use, by controlling the movement of the sliders of the horizontal linear guide rail 2 and the vertical linear guide rail 3, the position and angle of the camera 5 are adjusted to perform all-round visual inspection of the rotating product, obtain image information of different parts of the product, and detect whether there are defects or other problems in the product.

[0028] The product is placed on the second rubber pad 7 at the top of the turntable 65. The electric push rod 81 is activated, and the output shaft of the electric push rod 81 retracts, pulling the top plate 82 downward. The top plate 82 drives the fixed seat 83 to descend, and several linkage rods 84 inside the fixed seat 83 move accordingly. The linkage rods 84 drive the connecting seat 85 to move, and the connecting seat 85 drives the clamping rod 86 to move. The limiting slider 87 slides inside the limiting groove 88, which defines the movement trajectory of the limiting slider 87. Under the limiting action of the limiting slider 87, the clamping rod 86 moves horizontally towards the center of the turntable 65 together with the limiting slider 87, thereby achieving product clamping.

[0029] Start the motor 61. The output shaft of the motor 61 drives the gear 62 to rotate. The gear 62 drives the rotating drum 64 to rotate through the gear ring 63. The rotating disk 65 rotates accordingly, thereby rotating the product placed on it, so as to inspect the product from different angles.

[0030] This design, through the coordinated action of components such as the electric push rod 81, top plate 82, fixed base 83, linkage rod 84, connecting base 85, and clamping rod 86, can stably clamp and fix the product, ensuring that the product will not shake or shift during rotation, thus guaranteeing the accuracy of the test results. The cooperation of the limit slider 87 and the limit groove 88 provides precise guidance and limit for the movement of the clamping rod 86, making the clamping action more stable and reliable. Through the mutual cooperation of the electric push rod 81 and the motor 61, automatic clamping and rotation of the product are realized, reducing the intensity of manual labor and improving the automation level of the testing process.

[0031] Reference Figures 1-5 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a disassembly and assembly mechanism 4 is provided on one side of the vertical linear guide rail 3, and an installation frame 41 is fixedly connected to one side of the slider of the vertical linear guide rail 3. A limit groove 42 is opened on the bottom wall of the installation frame 41, and a T-shaped plate 51 is fixedly connected to the bottom end of the camera 5. The T-shaped plate 51 is slidably connected to the inner wall of the limit groove 42.

[0032] A pull rod 43 is slidably connected to the bottom wall of the mounting frame 41. One end of the pull rod 43 is fitted into the inner wall slot of the limiting groove 42, and the other end of the pull rod 43 extends to the outside of the mounting frame 41 and is fitted with a spring 44. One end of the spring 44 is fixedly connected to the pull rod 43 through a ring plate, and the other end of the spring 44 is fixedly connected to the side wall of the mounting frame 41.

[0033] A two-way screw 45 is rotatably connected to the top of the inner wall of the mounting frame 41. One end of the two-way screw 45 passes through the inner wall of the mounting frame 41 and is fixedly sleeved with a knob 46.

[0034] Both ends of the bidirectional lead screw 45 are threaded with clamping plates 47. A first rubber pad 48 is fixedly connected to the opposite side of the clamping plate 47, and the first rubber pad 48 is in contact with the side wall of the camera 5.

[0035] During use, when installing the camera 5, align the L-shaped plate 51 at the bottom of the camera 5 with the limiting groove 42 on the bottom wall of the mounting frame 41 and insert it into the limiting groove 42 to initially position the camera 5.

[0036] At this time, pull the rod 43 on the bottom wall of the mounting frame 41 to pull the rod 43 out of the slot in the inner wall of the limiting groove 42. The spring 44 is stretched. When the T-shaped plate 51 is fully inserted into the limiting groove 42, release the rod 43. Under the elastic force of the spring 44, the rod 43 is re-embedded into the slot in the inner wall of the limiting groove 42, fixing the T-shaped plate 51 and achieving the initial fixing of the camera 5.

[0037] Then, rotate the knob 46 on the top of the inner wall of the mounting frame 41. The knob 46 drives the bidirectional lead screw 45 to rotate. The clamping plates 47 connected to the outer surfaces of the two ends of the bidirectional lead screw 45 move towards each other under the action of the threads. The first rubber pad 48 on the opposite side of the clamping plate 47 contacts and clamps the side wall of the camera 5, further fixing the camera 5.

[0038] The design of the disassembly and assembly mechanism 4 makes the installation and disassembly of the camera 5 simple and convenient. Through the combination of components such as the pull rod 43, spring 44, double-acting screw 45 and clamping plate 47, the camera 5 can be quickly fixed in the mounting frame 41, and it can also be easily disassembled when it is necessary to replace or repair the camera 5, saving installation and maintenance time and costs.
