[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-3In this embodiment, a product inspection device using a camera is used to perform all-round photographing of the outer surface of the product through the camera, thereby improving the efficiency of the inspection of the outer surface of the product;

[0035] Specifically, it includes an operating table 1, a placing plate 2 for placing products, a gantry 3, a driving motor 4 and a turning mechanism 5; the placing plate 2 is arranged on the upper surface of the operating table 1, the gantry 3 is vertically installed on the operating table 1, and the inner top wall and the left and right sides of the inner wall of the gantry 3 are installed with detection cameras 6 for photographing the outer peripheral surface of the product;

[0036] The driving motor 4 is installed on the inner top wall of the operating table 1, and the output end of the driving motor 4 is transmission-connected to the placement tray 2 to drive the placement tray 2 and the product to rotate in the XZ direction; the flipping mechanism 5 is arranged on the operating table 1 to flip the product placed on the placement tray 2.

[0037] It should be noted that the detection camera 6 is connected to the external control terminal by telecommunications. The detection camera 6 transmits the images it captures to the control terminal, and the control terminal records and analyzes them to determine whether the outer surface of the product meets the factory requirements. That is, the control terminal mentioned in this application is consistent with the computer in the prior art and will not be elaborated here.

[0038] In actual use, the product is placed on the placement tray 2, and the three detection cameras 6 on the inner side of the gantry 3 photograph the product on the placement tray 2, and then the left and right sides and the upper surface of the product are photographed and transmitted to the control terminal, and then the output end of the driving motor 4 is rotated to drive the placement tray 2 to rotate, so that the product on the upper surface of the placement tray 2 is in a rotating state, and the left and right cameras on the inner side of the gantry 3 can photograph the front, back, left, and right sides of the product. After the front, back, left, right, and upper surface of the product are photographed, the product is flipped ninety degrees by the flipping mechanism 5, so that the original bottom of the product is aligned with the detection camera 6 on the side of the gantry 3, and the bottom of the product is photographed by the detection camera 6.

[0039] In actual configuration, the upper surface of the placement plate 2 is concave downward to form a concave portion, and the gantry 3 and the transverse center axis of the placement plate 2 are located in the same X-axis direction.

[0040] See also Figure 4-6 In order to flip the product and shoot the bottom of the product, the flip mechanism 5 in this embodiment includes a mounting plate 501 mounted on the operating table 1 by bolts, and a rotating shaft 502 rotatably connected to the inside of the mounting plate 501 by a bearing;

[0041] A driving structure is arranged on the mounting plate 501 and is transmission-connected to the rotating shaft 502 so as to drive the rotating shaft 502 to rotate on the ZX plane; a telescopic cylinder 503 is arranged at the front end of the rotating shaft 502, and a cross plate 504 is transmission-connected to the output end of the telescopic cylinder 503, and two double-axis cylinders 505 are symmetrically arranged on the front side of the cross plate 504, and the output ends of the two double-axis cylinders 505 are transmission-connected to the clamping plate 506.

[0042] During actual use, the output end of the telescopic cylinder 503 is extended to move the two clamps 506 to the two sides of the product, and then the output ends of the two dual-axis cylinders 505 are extended toward each other, so that the two clamps 506 are fitted with the left and right sides of the product to clamp the product. Then, the driving structure operates to rotate the shaft 502, and at the same time drives the two clamps 506 to rotate ninety degrees, so that the product located between the two clamps 506 rotates accordingly, and the product inside the clamp 506 is aligned with the detection camera 6 on the inner side of the gantry 3, and the detection camera 6 takes a picture of the bottom of the product.

[0043] Furthermore, in order to prevent the outer surface of the product from being damaged when the clamping plates 506 clamp the product, rubber pads are provided on opposite sides of the two clamping plates 506 in this embodiment.

[0044] In actual settings, by setting a rubber pad on the opposite side of the clamp 506, the direct contact and friction of the clamp 506 on the outer surface of the product when clamping the product is effectively reduced, thereby avoiding scratches, wear and other damages on the outer surface of the product and protecting the integrity and aesthetics of the product.

[0045] Furthermore, in order to ensure the stability of the clamping plates 506 when moving, a guide rail 507 is installed on the front side of the horizontal plate 504 along the X-axis direction, and the two clamping plates 506 are slidably connected to the outer side of the guide rail 507.

[0046] During actual setting, the clamp 506 slides on the outside of the guide rail 507 to ensure the stability and accuracy of the clamp 506 during movement. The guide rail 507 provides a fixed moving path for the clamp 506, effectively preventing the clamp 506 from shaking or deviating during movement, thereby improving the reliability and working efficiency of the entire clamping mechanism.

[0047] In addition, at least one side ear 508 is installed on both sides of the outer surface of the rotating shaft 502 ; corresponding to the side ear 508 , at least two guide rods 509 are set on the back side of the horizontal plate 504 , and the two guide rods 509 are respectively slidably connected to the inside of the side ear 508 .

[0048] In actual use, when the horizontal plate 504 moves forward and backward, it drives the guide rod 509 to slide inside the side ears 508 on the left and right sides. The two side ears 508 are limited to effectively improve the stability of the horizontal plate 504 when moving forward and backward.

[0049] In detail, in order to facilitate the driving of the rotating shaft 502 to rotate, the driving structure in this embodiment includes an electric push rod 510 assembled on the back of the mounting plate 501, and a gear plate 511 transmission-connected to the output end of the electric push rod 510, and a gear 512 meshing with the gear plate 511 is sleeved on the outer side of the rotating shaft 502.

[0050] In actual use, the output end of the electric push rod 510 is extended and retracted, thereby driving the tooth plate 511 to move left and right. Through the engagement between the tooth plate 511 and the gear 512, that is, when the tooth plate 511 is moving, the gear 512 will drive the inner rotating shaft 502 to rotate, thereby realizing the flipping of the product.

[0051] Furthermore, in order to improve the stability of the meshing between the tooth plate 511 and the gear 512 , a slide rail 513 is provided on the back of the mounting plate 501 in this embodiment, and the tooth plate 511 is slidably connected inside the slide rail 513 .

[0052] In actual use, the slide rail 513 provides a smooth and precise moving path for the tooth plate 511, which helps to ensure accurate and stable meshing of the tooth plate 511 with the gear 512, thereby improving the reliability and performance of the entire transmission mechanism.

[0053] A method for using a product inspection device using a camera is implemented according to the above-mentioned product inspection device using a camera, and includes the following steps:

[0054] S001: Place the product on the placement tray 2, shoot the product on the placement tray 2 through the three detection cameras 6 inside the gantry 3, and transmit the shot images to the control terminal;

[0055] S002: Then, the output end of the driving motor 4 rotates to drive the placement tray 2 to rotate, so that the product on the placement tray 2 is in a rotating state, and the two left and right cameras inside the gantry 3 can shoot the front, back, left and right sides of the product;

[0056] S003: After the front, back, left, right and top surfaces of the product are photographed, the product is flipped 90 degrees by the flipping mechanism 5 so that the original bottom of the product is aligned with the detection camera 6 on the side of the gantry 3, and the detection camera 6 takes a photo of the bottom of the product.
