[0013] To make the above-mentioned objects, 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. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] An automatic gating device for castings, characterized in that it includes: like Figure 1 As shown, the workbench 1 has a positioning fixture 2 on its upper side, and the positioning fixture 2 has a material picking station; like Figure 2 As shown, the linear module 3 is fixed on the upper side of the workbench 1. The linear module 3 is equipped with a feeding gripper 35, which is used to move the product at the position of the positioning fixture 2 to the material picking station. The sanding belt structure 5 is equipped with a grinding wheel, and a support plate is provided on the side of the grinding wheel; The robotic arm 4 is used to move the product from the material handling station to the sanding belt structure 5 and grind it at the sanding belt structure. When the robotic arm fixes the product on the outside of the grinding wheel for grinding, the product abuts against the upper side of the support plate. Material collection structure 6 is used to collect the polished products.

[0017] During the production process, the product is first moved to the picking station near the robot 4 by the moving module. Then the robot 4 moves the product from the picking station to the sanding belt structure 5 for grinding. After grinding, the product is collected by the material collection structure 6. In this process, the moving module is added to move the product, which can reduce the movement path of the robot 4, increase the production cycle, and thus improve production efficiency.

[0018] like Figure 2 As shown, the product is placed at the positioning fixture 2. Therefore, in order to position the placed product, in this embodiment, the positioning fixture 2 is provided with several positioning slots 21 for placing the product. The picking station is the positioning slot 21 near the robot arm 4. The upper side of the positioning fixture 2 is provided with several horizontal and vertical partitions, thereby dividing it into several positioning slots 21. The product is placed in the positioning slot 21 to position the product. At this time, the picking station is a positioning slot 21 near the robot arm 4. That is, all products at the positioning fixture 2 position are first moved to the specific positioning slot 21 (picking station) position by the linear module 3, and then the robot arm 4 moves the product to the sanding belt structure 5 for grinding. In this way, the robot arm 4 does not need to move to every positioning slot 21 to pick up the product, thereby reducing the movement path of the robot arm 4, thereby improving the production cycle and production efficiency.

[0019] At this point, two positioning fixtures 2 are provided. To remove the product from the position of the positioning fixture 2, a structure is provided to control the movement of the positioning fixture 2. Specifically, a longitudinal guide rail 11 is provided on the upper side of the worktable 1, and a slider is provided on the upper side of the longitudinal guide rail 11. The positioning fixture 2 is fixed to the upper side of the slider. A cylinder 12 for driving the movement of the positioning fixture 2 is also fixed on the upper side of the worktable 1. The piston rod of the cylinder 12 is fixed to the bottom of the positioning fixture 2. Under the action of the cylinder 12, the positioning fixture 2 moves longitudinally along the longitudinal guide rail 11, thereby allowing the product to move longitudinally.

[0020] like Figure 2As shown, when the positioning fixture 2 moves longitudinally, in order to remove the product from the positioning slot 21 of the positioning fixture 2, it is also necessary to move laterally. Therefore, in this embodiment, the linear module 3 includes two uprights 31 fixed on the upper side of the worktable 1. A lateral movement module 32 is provided on the upper side of the two uprights 31. The lateral movement module 32 is provided with a lateral movement plate. A longitudinal movement module 33 is provided on the side of the lateral movement plate. A longitudinal movement module 33 is provided with a longitudinal movement plate. A vertical movement module 34 is provided on the side of the longitudinal movement plate. A vertical movement module 34 is provided with a vertical movement plate. The loading gripper 35 is fixed on the side of the vertical movement plate. The horizontal moving module 32 is set perpendicular to the vertical guide rail 11. Under the action of the horizontal moving module 32 and the vertical moving module 33, the loading gripper 35 can move horizontally and vertically. At the same time, under the action of the vertical moving module 34, the loading gripper 35 can move vertically, thereby taking out the product at the position of the positioning slot 21 on the worktable 1 and moving it to the picking station.

[0021] At this time, the lateral movement module 32, the longitudinal movement module 33, and the vertical movement module 34 adopt linear movement modules, such as linear motors or motor screw structures, to achieve lateral and vertical movement.

[0022] like Figure 2 As shown, the loading gripper 35 is used to fix the product. Therefore, in this embodiment, the loading gripper 35 includes a rotary cylinder 12 fixed to the side of the vertical moving plate. A finger cylinder 12 is fixed to the rotating part of the rotary cylinder 12, and a gripper is provided at the moving end of the finger cylinder 12. Under the action of the rotary cylinder 12, the finger cylinder 12 can rotate at a corresponding angle. Under the action of the finger cylinder 12, the product can be clamped by the gripper, thereby realizing the clamping, rotation, and horizontal, vertical, and longitudinal movement of the product, completing the movement of the product from the positioning groove 21 to the picking station.

[0023] like Figure 1 and Figure 3As shown, during the grinding process of the gate, since the grinding wheel rotates, to prevent the product from deflecting downwards due to the rotation of the grinding wheel, in this embodiment, the abrasive belt structure 5 includes a grinding wheel, and a support plate 51 is provided on the side of the grinding wheel. The support plate 51 is located on the outer side of the grinding wheel. When the robot arm 4 fixes the product on the outer side of the grinding wheel for grinding, the support plate 51 is located on the lower side of the product. With the support plate 51 located on the lower side of the product, when the robot arm 4 moves the product to the outer side of the grinding wheel, the rotation of the grinding wheel will cause the product to deflect tangentially in the direction of rotation. For example, if the grinding wheel rotates clockwise, the product will deflect downwards during grinding. The support plate 51 provides upward support for the product, limiting the downward tilt of the product during grinding. Therefore, the quality of the product being moved to the grinding wheel by the robot arm 4 can be guaranteed.

[0024] Finally, as Figure 1 and Figure 3 As shown, after the product's gate is ground, it needs to be collected. To improve collection efficiency, in this embodiment, the material collection structure 6 includes an inclined trough 61. The higher end of the inclined trough 61 is located outside the grinding wheel, and the lower end of the inclined trough 61 is provided with a collection box 62. The inclined trough is in an inclined state and has a groove for the product to slide. The higher side is located outside the grinding wheel, and the lower side is provided with a collection box 62 for collection. In this way, after the product is ground, the robot arm 4 can be directly released from its clamping position on the product, and the product falls into the inclined trough and then slides along the inclined trough into the collection box 62, thereby completing the collection of the ground product. At this time, it is not necessary to specially place and collect the product using the robot arm 4, which can reduce the working stroke of the robot arm 4 and thus improve the product grinding efficiency.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
