Among them, the rejection mechanism support leg 703 is on the main frame body 1 of the defect detection device. The transition support plate 701 is fixed on the support plate 702, and the support plate 702 is fixed on the top of the rejection mechanism support leg 703 through a connecting plate 707. The transition support plate 701 is used to assist the second-stage flipping and clamping detection mechanism 14 to support the square ham. The rejection guide shaft 704 and the rejection cylinder 708 are arranged in parallel on the rejection mechanism support leg 703, and the rejection guide shaft 704 is slidably matched with the guide shaft sleeve 705 at the upper part of the front end of the rejection mechanism support leg 703. The output end of the rejection cylinder 708 is connected to the rejection push block 709. When the rejection cylinder 708 extends, it rejects the unqualified square ham through the rejection push block 709. A cylinder air nozzle 706 is fixed on the rejection cylinder 708. When the detection signal is given to the rejection mechanism 7, the rejection cylinder 708 acts to effectively reject the defective products.

[0059] Specifically, the rejection mechanism 7 is embedded inside the secondary flipping clamping and detecting mechanism 14 and fixed on the main frame 101 of the main frame body 1 of the defect detection device, and does not interfere with any rotating components, which can effectively reject defective products.

[0060] As Figure 1 shown, on the basis of the above embodiment, a defect detection device for square ham provided by the present invention further includes a buffer acceleration conveyor belt 8 and a feeding sorting and positioning mechanism 9; the buffer acceleration belt 8 is placed in the front left of the main frame body 1 of the defect detection device and is connected to the main frame body 1 of the defect detection device, and the outlet corresponds to the feeding sorting and positioning mechanism 9.

[0061] As Figure 10 shown, in the embodiment of the present invention, the buffer acceleration conveyor belt 8 includes buffer belt support legs 801, a buffer conveyor belt body 802, an acceleration conveyor belt body 804, a detection in-place sensor 806, a limit air cylinder 807 and a bracket 808. Among them, the buffer belt support legs 801 are vertically arranged at the feeding end of the main frame body 1 of the defect detection device, and the buffer conveyor belt body 802 and the acceleration conveyor belt body 804 are sequentially arranged on the buffer belt support legs 801 and have the same transmission direction. The buffer conveyor belt body 802 and the acceleration conveyor belt body 804 achieve effective separation of square ham through a speed difference. The detection in-place sensor 806 and the limit air cylinder 807 are arranged on the buffer belt support legs 801 through the bracket 808 and are located on one side of the acceleration conveyor belt body 804. The detection in-place sensor 806 is used to detect whether the square ham is separated by a distance. If there is a square ham that has not been separated by a distance, it is effectively separated by the limit air cylinder 807.

[0062] Specifically, the buffer conveyor belt body 802 is fixed on the buffer belt support legs 801, and the buffer conveyor drive motor 803 is fixed at the front end of the buffer conveyor belt body 802 and is connected to the drive shaft, which can arrange the square ham 809 in rows in sequence.

The detection in-place sensor 806 is fixed on the middle rear upper of the acceleration conveyor belt body 804 through the bracket 808 and is used to detect whether the square ham 809 is separated by a distance. If there is a square ham 809 that has not been separated by a distance, it is effectively separated by the limit air cylinder 807, and finally the acceleration separation of the product is realized.

[0063] As Figure 11As shown in the figure, in the embodiment of the present invention, the feeding sorting and positioning mechanism 9 includes a full sausage detection sensor 901, a mechanism cavity 902, a positioning cylinder push block 903, a positioning cylinder bracket 904, a positioning cylinder 905 and a sensor bracket 906. Among them, the mechanism cavity 902 is arranged at the feeding end of the main frame body 1 of the defect detection device and is used to receive the square ham conveyed by the buffer acceleration conveyor belt 8. An opening is provided on the side of the mechanism cavity 902. The positioning cylinder 905 is arranged at the side opening of the mechanism cavity 902 through the positioning cylinder bracket 904, and the output end is connected to the positioning cylinder push block 903. When the positioning cylinder 905 extends, it can position the square ham in the mechanism cavity 902 through the positioning cylinder push block 903. The full sausage detection sensor 901 is arranged on the top of the mechanism cavity 902 through the sensor bracket 906, and the full sausage detection sensor 901 is used to detect whether the mechanism cavity 902 is full of square ham.

[0064] Specifically, the feeding sorting and positioning mechanism 9 is fixed on the driven end side plate of the horizontal and rotation detection mechanism 2, and provides products to the horizontal and rotation detection mechanism 2 in sequence. The full sausage detection sensor 901 is fixed directly above the mechanism cavity 902 through the sensor bracket 906, and the entrance of the mechanism cavity 902 corresponds exactly to the exit of the acceleration conveyor belt body 804. When the full sausage detection sensor 901 detects that the product in the mechanism cavity 902 is full, the buffer acceleration conveyor belt 8 stops running, and the positioning cylinder 905 then orderly drops the product onto the conveyor belt of the detection conveyor mechanism 203 at time intervals.

[0065] In the embodiment of the present invention, the first-level flipping and clamping detection mechanism 3 and the second-level flipping and clamping detection mechanism 14 have the same structure and are respectively connected to two sets of synchronous drive wheel assemblies 10. The synchronous drive wheel assemblies 10 are used for transmission connection with adjacent process units. Specifically, the synchronous drive wheel assemblies 10 are fixed on the main frame 101 of the defect detection device main frame body 1, and can realize the synchronization of the horizontal and rotation detection mechanism 2 and the first- and second-level flipping and clamping detection mechanisms.

[0066] As Figure 12 shown, in the embodiment of the present invention, the two sets of synchronous drive wheel assemblies 10 are respectively the first synchronous drive wheel assembly 1001 and the second synchronous drive wheel assembly 1002, and both the first synchronous drive wheel assembly 1001 and the second synchronous drive wheel assembly 1002 are belt drive mechanisms. The flipping and clamping mechanism drive motor 302 of the first-level flipping and clamping detection mechanism 3 transmits power to the horizontal and rotation detection mechanism 2 through the first synchronous drive wheel assembly 1001 to achieve synchronization between the two; similarly, the drive motor of the second-level flipping and clamping detection mechanism 14 transmits power to the second-level conveying and detection mechanism 4 through the second synchronous drive wheel assembly 1002, and at the same time drives the conveying drive assembly 601 to work to achieve synchronization among the three.

[0067] The present invention provides a defect detection device for square ham, and its working principle is as follows:

[0068] The square hams 809 on the buffer acceleration conveyor belt 8 are arranged in an orderly manner on the conveyor belt. The effective separation of the square hams 809 is achieved through the acceleration conveyor belt body 804, and they enter the mechanism cavity 902 of the feeding and sorting mechanism 9 in sequence. Under the action of the positioning cylinder 905, the square hams 809 enter the conveyor belt of the detection conveyor mechanism 203 at time intervals, and successively pass through the image detection mechanism I 207, the horizontal electrode detection mechanism 206, and the rotating electrode detection mechanism 202 to realize the defect detection of the upper surface and the left and right side surfaces of the square ham 809. Under the action of the pressing and clamping mechanism 205, the square ham 809 is smoothly transferred to the push block of the flipping drive assembly 303 of the first-level flipping and clamping detection mechanism 3. During this rotation process, through the image detection mechanism II 304 and the flipping electrode detection mechanism 305, the single-sided detection (front side) of the square ham 809 is realized, and the flipping and turning of the square ham 809 are realized, that is, the rear side of the square ham 809 after flipping faces upward. Under the combined action of the loading and unloading clamping mechanism 5 and the transfer conveyor mechanism 6, the square ham 809 is smoothly transferred to the conveyor chain of the secondary conveyor mechanism 403 of the secondary conveyor detection mechanism 4. Then, through the image detection mechanism III 405 and the secondary electrode detection mechanism 402, the defect detection of the rear side of the square ham 809 is realized, and it is smoothly conveyed to the secondary flipping and clamping detection mechanism 14 through the clamping conveyor mechanism 407 above the discharge port. Similarly, during this rotation process, through the secondary flipping image detection mechanism and the secondary flipping electrode detection mechanism, the detection of the last surface (bottom surface) of the square ham 809 is realized. After multi-stage image and electrode detections, if there are defective square hams 809, they are effectively removed through the removal mechanism 7 at the outlet of the secondary flipping and clamping detection mechanism 14. If the detection is qualified, the square ham 809 enters the next process for packaging, and finally, the all-round defect detection of the square ham 809 is completed.

[0069] Specifically, the pneumatic assembly mainly includes an air source processor, a switch valve, a solenoid valve, a regulating valve, etc., and is mainly used to control the actions of all cylinders.

[0070] The present invention provides a defect detection device for square ham, which can perform multi-directional defect detection on square ham, effectively remove defective ones, reduce the labor intensity of workers, improve the detection efficiency, and improve the overall work efficiency. In addition to being able to realize the defect detection of six surfaces of the square ham, this defect detection device can also effectively sort, convey, clamp and flip the square ham. At the same time, a detection and removal mechanism is added, which can timely alarm, remove and collect defective square hams, reduce the visual fatigue and labor intensity caused by long-term manual detection, greatly improve the detection efficiency of square ham, and improve the production efficiency of enterprises.
