[0026] like Figures 1-4 As shown, a loading and unloading mechanism for plane grinding includes a guide star plate 1 driven by a drive assembly to rotate and realize feeding and discharging actions. The guide star plate 1 is provided with a plurality of feeding holes 2 evenly spaced in a circular shape. The product to be ground is fed through the feeding holes 2. The mechanism includes a feeding positioning device 7 provided on the guide star plate 1 at the product inlet of the grinder, a qualified judgment device 11 provided on the guide star plate 1 at the product outlet of the grinder, and an abnormal discharge device 14 provided on the guide star plate 1 at the outlet of the grinder.

[0027] A loading robot 3 cooperating with a loading positioning device 7 is provided at the product entrance of the grinding machine, and a unloading robot 5 cooperating with a qualified judgment device 11 is provided at the product exit of the grinding machine.

[0028] Specifically, as shown in the figure, the feeding and positioning device 7 includes a product placement and positioning jig 8 arranged directly above the guide star disk 1. The product placement jig 8 is provided with a feeding port 4. The feeding port 4 corresponds to the feeding hole 2 of the guide star disk 1 up and down. The product placement and positioning jig 8 is provided with a feeding positioning abnormality alarm sensor 9. The loading robot 3 clamps the product to be ground and puts it into the feeding port 4. After the product is placed into the feeding port 4, the guide star disk 1 rotates to make the product fall into the hole of the guide star disk 1 and be brought into the grinder for operation. If the product is not brought into the hole after feeding, the product will appear to push against the product placement and positioning jig 8 to move forward, forcing the feeding positioning abnormality alarm sensor 9 to trigger a signal, the equipment stops feeding, and the guide star disk 1 stops rotating.

[0029] Specifically, as shown in the figure, the qualified judgment device 11 includes a material sensor 12 arranged at the product outlet of the grinding machine, and an NG judgment sensor 13, the material sensor 12 judges whether the ground product is sent out, and the NG judgment sensor 13 judges whether the product is qualified, after judging qualified, the product is put into the unloading code disc by the unloading robot 5 through the unloading gripper opening 6, and after judging unqualified, the product is put into the NG storage area by the unloading robot 5 through the unloading gripper opening 6. When the product is ground and passes through the qualified judgment device 11, when the material sensor 12 is triggered, the unloading robot 5 will intercept the rotating speed of the star wheel 10, and at the same time, the unloading robot 5 moves to the unloading gripper opening 6, and the unloading robot 5 tracks the product movement in a synchronous and same-speed mode, so that when the NG judgment sensor 13 is triggered by the rear product, it is judged that the product is OK, and the unloading code disc is performed, and if the NG judgment sensor 13 is not triggered, it is judged that the product is NG, and the product is placed in the NG storage area by the unloading robot 5 for collection.

[0030] Specifically, as shown in the figure, the abnormal discharge device 14 is arranged below the qualified judgment device 11, and includes a drop opening 15, a slide 16 for receiving the product dropped from the drop opening 15, and a temporary storage box 17 arranged at the bottom end of the slide 16, and the drop opening 15 is located directly below the star wheel 1. When the equipment abnormally stops due to failure or the like, the product not clamped by the unloading robot 5 will automatically drop into the abnormal discharge buffer device 14 and slide into the temporary storage box 17 from the slide 16 through the drop opening 15, so as to prevent the product from entering the grinding machine again and causing repeated grinding size defects.

[0031] Specifically, as shown in the figure, a support plate is arranged below the star wheel 1, and the support plate is arranged at the position of the drop opening 15 and is provided with a discharge opening communicated with the upper feeding hole 2.

[0032] Specifically, as shown in the figure, an upper feeding sensor 10 for sensing whether there is product in the feeding hole 2 is arranged in front of the upper feeding positioning device 7. When the sensor does not detect product in the feeding hole 2 of the star wheel 1, the upper feeding robot 3 will be triggered to perform feeding work.

[0033] Specifically, as shown in the figure, the star wheel 1 is installed in the middle of the upper and lower grinding wheel discs of the grinding machine.

[0034] Specifically, the specific implementation principle of the utility model is:

[0035] 1. The upper feeding robot 3 grasps the product to be ground from the outside and puts it into the feeding opening 4 of the product feeding positioning jig 8.

[0036] The product feeding positioning jig 8 ensures that the product accurately falls into the feeding hole 2 of the star wheel 1.

[0037] The feeding sensor 10 senses whether there is product in the feeding hole 2 to ensure the accuracy of the feeding process.

[0038] 2. The guide star disc 1 rotates under the drive of the drive assembly, and the products are sequentially sent into the middle of the upper and lower grinding wheels of the grinder for grinding.

[0039] 3. The ground product continues to rotate along the guide star disk 1 to the product outlet of the grinder.

[0040] The material presence sensor 12 first determines whether the ground product has been delivered.

[0041] The NG determination sensor 13 performs quality inspection on the product to determine whether it is qualified.

[0042] If the product is qualified, the unloading robot 5 grabs the product at the unloading clamping port 6 and puts it into the unloading code tray for collection.

[0043] If the product is unqualified, the unloading robot 5 places the product into the NG storage area.

[0044] 4. When the equipment stops abnormally due to a fault, the products not gripped by the unloading robot 5 will automatically fall into the abnormal discharge buffer device 14 and slide from the slide 16 into the temporary storage box 17 through the drop opening 15.

[0045] The loading device of this utility model can cooperate with the robot to realize non-stop feeding and position and correct the released products; the unloading trigger device can realize product status judgment. In conjunction with the unloading robot, it can realize uninterrupted unloading at the same speed and speed; the abnormal discharge device can realize unified collection of products in the grinder when the robot stops working due to fault, preventing them from entering the grinder again and causing dimensional defects; in conjunction with the conveying device of the upper and lower workstations, the operator can switch from manual feeding to process monitoring and control and control of incoming materials at the upper workstation.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0047] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
