[0025] To make the objects, features, and advantages of the present invention more readily apparent, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The accompanying drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0026] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a device for rejecting defective products in filling product packaging based on depth vision, which is applied to a filling product production line 120 and includes a working support 10 and a rejection mechanism. The rejection mechanism is arranged on the working support 10 and faces the filling product production line 120.

[0027] The rejection mechanism includes a power structure 20 and a detection structure 30. The power structure 20 includes a cylinder support 21 and a first cylinder 22 disposed in the cylinder support 21. The protruding end of the first cylinder 22 protrudes outside the cylinder support 21.

[0028] The detection structure 30 includes a first rotating arm 31 and a second rotating arm 32 symmetrical to each other. The first rotating arm 31 and the second rotating arm 32 are respectively rotatably connected to the output end of the first cylinder 22. The first rotating arm 31 and the second rotating arm 32 are respectively provided with a first camera 60 and a second camera 70 on the surface facing the filling product production line 120. The first camera 60 and the second camera 70 form a preset acute angle. The convergence direction of the first camera 60 and the second camera 70 is away from the bottle cap of the filling product. The angle between the first camera 60 and the second camera 70 is changed by raising and lowering the output end of the first cylinder 22.

[0029] The first and second rotating arms 31 and 32 are rotatably connected to a first and second control arm assemblies 40 and 50 at their ends away from the protruding ends. The first and second control arm assemblies 40 and 50 are rotatably connected to the cylinder bracket 21 .

[0030] The working principle of the present invention is as follows: during the capping process of the filling product production line 120, the bottle cap may be missing, crooked, or damaged. The filling product packaging defective product rejection equipment based on depth vision of the present invention can detect and reject abnormal bottle caps. By raising and lowering the first cylinder 22, the angle between the first rotating arm 31 and the second rotating arm 32 is adjusted to adapt to different bottle cap sizes and bottle body heights. For example, when the bottle cap size is small, the protruding end of the first cylinder 22 rises, thereby reducing the angle between the first rotating arm 31 and the second rotating arm 32, so that the first camera 60 and the second camera 70 are close to the four sides of the bottle cap. The first camera 60 and the second camera 70 take pictures of the bottle cap at the best angle, so as to more accurately judge the abnormality of the bottle cap. For example, when the height of the bottle body becomes higher, the protruding end of the first cylinder 22 rises, and then the first camera 60 and the second camera 70 rise upward and away from the bottle body, so that the camera takes pictures of the bottle cap at the best angle.

[0031] The filled product is transported to the bottom of the detection structure 30 via the conveyor belt, and the bottle cap of the filled product is exactly located between the first camera 60 and the second camera 70. The photos taken by the first camera 60 and the second camera 70 are transmitted to the industrial computer. When the industrial computer detects that the bottle cap in the photos taken by the first camera 60 and the second camera 70 is abnormal, the first cylinder 22 is started to rise, and the first control arm assembly 40 and the second control arm assembly 50 approach each other to clamp the bottle of the filled product and remove it from the production line.

[0032] From the above description, it can be seen that the filling product packaging defective product rejection device based on depth vision of the present invention has the following beneficial effects: the filling product packaging defective product rejection device based on depth vision provided by the present invention sets the camera on the first rotating arm 31 and the second rotating arm 32, and adjusts the angle between the cameras by controlling the lifting and lowering of the first cylinder 22, so that the cameras are always distributed on the opposite sides of the bottle cap of the filling product, and then can clearly take pictures around the bottle cap, so as to more accurately judge the abnormality of the bottle cap. At the same time, when the abnormality of the bottle cap is judged, the control arm assembly is continued to be driven by the lifting of the first cylinder 22 to clamp the bottle body, so that the abnormal filling product is separated from the production line. The detection and rejection of the present invention are integrated, which can greatly improve the rejection efficiency.

[0033] Specifically, the first control arm assembly 40 includes a first transmission member 41 and a second transmission member 42. The end of the first transmission member 41 is rotatably connected to the end of the second transmission member 42. A first clamping portion 43 is provided at the end of the second transmission member 42 distal from the first transmission member 41. The first clamping portion 43 includes a second cylinder 431 disposed within the first clamping portion 43. The output end of the second cylinder 431 faces the bottle body of the filled product. A first flexible layer 432 is provided on the surface of the bottle body facing the filled product.

[0034] Specifically, the second control arm includes a third transmission member 51 and a fourth transmission member 52. The end of the third transmission member 51 is rotatably connected to the end of the fourth transmission member 52. A second clamping portion 53 is provided on the end of the fourth transmission member 52 distal from the third transmission member 51. The second clamping portion 53 includes a third cylinder 531 disposed within the second clamping portion 53. The output end of the third cylinder 531 faces the bottle body of the filled product. A second flexible layer 532 is provided on the surface of the bottle body facing the output end of the third cylinder 531.

[0035] From the above description, it can be seen that the beneficial effect is that: the first control arm assembly 40 and the second control arm assembly 50 have the same structure. When the industrial computer detects that the bottle cap of the filled product is abnormal through the photos taken by the camera, the industrial computer controls the second cylinder 431 and the third cylinder 531 to extend synchronously, so that the first clamping part 43 of the first control arm assembly 40 and the second clamping part 53 of the second control arm assembly 50 are close to each other to clamp the abnormal bottle cap of the filled product, thereby completing the removal of defective products.

[0036] In order to prevent the second cylinder 431 from damaging the bottle cap when clamping the bottle cap, a first flexible layer 432 and a second flexible layer 532 are provided on the surface of the second cylinder 431 to contact the bottle cap, thereby protecting the bottle cap.

[0037] Specifically, the cylinder bracket 21 is provided with a first output shaft 90 at one end close to the working bracket 10. The first output shaft 90 passes through the working bracket 10. The end of the first output shaft 90 is provided with a transmission gear 100. The transmission gear 100 is meshed and connected to a transmission motor 110.

[0038] From the above description, it can be seen that the beneficial effect is: in order to be able to take pictures of the bottle caps of the filled products from various angles, the transmission motor 110 drives the transmission gear 100 to rotate, and then drives the cylinder bracket 21 to rotate. The rotation of the cylinder bracket 21 finally drives the camera at the output end of the cylinder to rotate, so that the camera can take pictures of the bottle caps of the filled products from various angles, and can more accurately judge the abnormality of the bottle caps.

[0039] Specifically, a third camera 80 is provided on a surface of the output end of the first cylinder 22 facing the filling product production line 120 . The third camera 80 is disposed between the first rotating arm 31 and the second rotating arm 32 .

[0040] From the above description, it can be seen that the beneficial effect is that the third camera 80 is set to directly take a photo of the top of the bottle cap, and combined with the photos of the bottle cap taken from the side by the first camera 60 and the second camera 70, the abnormality of the bottle cap can be more accurately judged from the top and side photos.

[0041] In summary, the depth vision-based defective product rejection device for filling product packaging provided by the present invention has the following beneficial effects: the camera is set on the first rotating arm 31 and the second rotating arm 32, and the angle between the cameras is adjusted by controlling the lifting and lowering of the first cylinder 22, so that the cameras are always distributed on opposite sides of the bottle cap of the filled product, thereby being able to clearly take pictures of the bottle cap and thus more accurately judge the abnormality of the bottle cap. At the same time, when the bottle cap is judged to be abnormal, the control arm assembly is driven to clamp the bottle body by continuing to control the lifting of the first cylinder 22, so that the abnormal filled product is removed from the production line. The detection and rejection of the present invention are integrated, which can greatly improve the rejection efficiency.

[0042] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
