[0036] See also Figure 1-Figure 5 .

[0037] The present application discloses a material feeding guide device which can be applied to the grinding process in the production process of metal oxide resistors, and is used to guide the material fed into the loading plate 3 to prevent the material from tilting after being fed into the loading plate 3, thereby reducing the risk of chuck during the grinding process.

[0038] The carrier plate 3 has a material hole 31 for carrying the material to be processed. The number of the material holes 31 of the carrier plate 3 is at least two. Figure 4 As shown, the carrier plate 3 is a circular plate, and 8 material holes 31 are evenly distributed on the circumference of the carrier plate 3. The material holes 31 are used to limit the material to prevent the material from changing position during processing. In the production process of metal oxide resistors, the material is ground on the carrier plate 3.

[0039] The material unloading guide device includes a guide plate 1 and a clamping block 2.

[0040] One side of the guide plate 1 is in contact with the carrier plate 3, and a clamping block 2 is provided on the other side of the guide plate 1. The clamping block 2 is used to cooperate with the loading and unloading device. The loading and unloading device picks up the guide plate 1 through the clamping block 2 to place the guide plate 1 on the carrier plate 3 or remove the guide plate 1 from the carrier plate 3.

[0041] A guide hole 11 for guiding the material is provided on the guide plate 1. The guide hole 11 is a conical hole. The larger end of the conical hole is the feed port, and the smaller end of the conical hole is the discharge port. The material enters the guide hole 11 through the feed port and falls into the material hole 31 of the carrier plate 3 through the discharge port. The position of the discharge port of the guide hole 11 corresponds to the position of the material hole 31. The guide hole 11 is used to prevent the material from tilting during the process of entering the material hole 31, to ensure that the material does not tilt after entering the material hole 31, so that the material can be stacked in place at one time, reducing the risk of chuck during the grinding process.

[0042] The material discharge guiding device disclosed in the present scheme guides the material to be discharged into the material hole 31 of the loading tray 3 through the guide hole 11, and corrects the inclination of the material during the discharge process to ensure that the material is stacked in place in the material hole 31 at one time, thereby improving the efficiency of material stacking.

[0043] like Figure 4 As shown, the material hole 31 of the carrier plate 3 is a circular hole, the guide hole 11 is coaxial with the material hole 31 , and the shape of the discharge port of the guide hole 11 is the same as that of the material hole 31 .

[0044] The diameter of the feed port of the guide hole 11 is larger than the diameter of the material hole 31, the diameter of the discharge port of the guide hole 11 is equal to the diameter of the material hole 31, and the diameter of the material hole 31 is equal to the diameter of the material. When the material passes through the guide hole 11, the inner wall of the guide hole 11 limits each position of the material in the circumferential direction to ensure the reliability of guiding the material.

[0045] In some embodiments, the angle between the hole wall of the guide hole 11 and the axis of the guide hole 11 is 15°-45°, and the greater the thickness of the guide plate 1 is, the greater the angle between the hole wall of the guide hole 11 and the axis of the guide hole 11 is.

[0046] The greater the thickness of the guide plate 1 is and the longer the length of the guide hole 11 is, the better the guiding effect of the guide plate 1 on the material is.

[0047] When the thickness of the guide plate 1 is large, the length of the guide hole 11 opened on the guide plate 1 is long. In order to facilitate the material to enter the guide hole 11, the angle between the hole wall of the guide hole 11 and the axis of the guide hole 11 can be appropriately increased to increase the area of ​​the feed port of the guide hole 11.

[0048] When the thickness of the guide disk 1 is small, the length of the guide hole 11 opened on the guide disk 1 is short. In order to ensure the guiding effect of the guide hole 11 on the material, the angle between the hole wall of the guide hole 11 and the axis of the guide hole 11 can be appropriately reduced.

[0049] The number of guide holes 11 provided on the guide plate 1 may be equal to or different from the number of material holes 31 of the carrier plate 3. Preferably, the number of guide holes 11 of the guide plate 1 is equal to the number of material holes 31 of the carrier plate 3, so that the guide plate 1 can guide the materials placed in the material holes 31 of the carrier plate 3, and the guiding of the materials placed in the material holes 31 can be realized by the one-time cooperation between the guide plate 1 and the carrier plate 3.

[0050] After the loading and unloading device picks up the guide plate 1 through the clamping block 2, the loading and unloading device places the guide plate 1 on the carrier plate 3, and then the loading and unloading device picks up the material at the loading position and places the picked up material into the material hole 31 of the carrier plate 3 through the guide hole 11 of the guide plate 1.

[0051] After the material hole 31 of the carrier plate 3 is filled with material, the loading and unloading device picks up the guide plate 1 through the clamping block 2 and places the guide plate 1 at a position where it does not affect the grinding disc. The grinding machine grinds the material on the carrier plate 3. After grinding, the loading and unloading device picks up the material in the material hole 31 of the carrier plate 3 and places it at the unloading position.

[0052] The clamping block 2 and the guide plate 1 may be formed integrally or in separate structures.

[0053] In the embodiment where the clamping block 2 and the guide plate 1 are separate structures, the clamping block 2 is connected to the guide plate 1 by bolts. Specifically, the guide plate 1 is provided with bolt holes, and the clamping block 2 may also be provided with bolt holes, and the guide plate 1 and the clamping block 2 are connected by bolts that match the bolt holes.

[0054] The clamping block 2 and the guide plate 1 may also be connected by welding, riveting or magnetic attraction.

[0055] In order to reduce the difficulty of matching the guide plate 1 with the carrier plate 3 , the material unloading guide device disclosed in the present solution further includes a positioning component, and the guide plate 1 is positioned and connected to the carrier plate 3 via the positioning component.

[0056] In some embodiments, the positioning assembly includes a positioning protrusion 5 and a positioning groove 4 . The positioning protrusion 5 is disposed on a side where the guide plate 1 is in contact with the carrier plate 3 , and the positioning groove 4 is provided on the carrier plate 3 .

[0057] The number of the positioning protrusions 5 and the positioning grooves 4 of the positioning assembly is at least two, so as to limit the guide plate 1 circumferentially, prevent the position of the guide plate 1 from changing when the material is lowered into the guide hole 11, and improve the limiting and guiding effect of the guide plate 1 on the material.

[0058] Specifically, after the guide plate 1 and the carrier plate 3 are matched by the positioning assembly, the guide hole 11 of the guide plate 1 corresponds to the position of the material hole 31 of the carrier plate 3, and the position of the guide plate 1 does not need to be adjusted.

[0059] The positioning protrusion 5 and the guide plate 1 can be integrally formed or separated. In the embodiment where the positioning protrusion 5 and the guide plate 1 are separated, a screw is provided on the positioning protrusion 5, and a through hole matching the screw is provided on the guide plate 1. The screw of the positioning protrusion 5 passes through the through hole of the guide plate 1 and is locked on the guide plate 1 by a nut. Optionally, a gasket is provided between the nut and the guide plate 1.

[0060] like Figure 1 As shown, the positioning protrusions 5 are located on both sides of the clamping block 2. The positioning grooves 4 of the carrier plate 3 can also be used as a structure for the visual system of the loading and unloading device to perform angle positioning on the carrier plate 3, so as to facilitate the cooperation between the guide plate 1 and the carrier plate 3, and the positioning of the material hole 31 during the loading and unloading process; accordingly, the nut of the guide plate 1 can also be used as a structure for the visual system of the loading and unloading device to perform angle positioning on the guide plate 1, so as to facilitate the cooperation between the guide plate 1 and the carrier plate 3.

[0061] The shape of the guide plate 1 and the shape of the carrier plate 3 may be the same or different.

[0062] In the embodiment where the shape of the guide plate 1 is the same as that of the carrier plate 3, the size of the guide plate 1 is also equal to that of the carrier plate 3. After the guide plate 1 is matched with the carrier plate 3, the space occupied by the material discharge guide device on the periphery of the carrier plate 3 is reduced.

[0063] In the embodiment where the shape of the guide plate 1 is different from the shape of the carrier plate 3, the shape of the guide plate 1 can be designed according to actual needs, such as a petal shape that is the same as the multiple material holes 31 of the carrier plate 3, or a rectangle or other polygons.

[0064] The clamping block 2 may be disposed at least one position in the middle and the periphery of the guide plate 1. Figure 1 As shown, it is an embodiment in which the clamping block 2 is arranged in the middle of the guide plate 1. The middle of the guide plate 1 is located in an annular structure surrounded by multiple guide holes 11. The middle of the guide plate 1 is a solid structure, which can ensure the fixing strength of the clamping block 2 and provide a sufficiently large installation space for the clamping block 2. On the other hand, it can also increase the volume of the clamping block 2.

[0065] The clamping block 2 is arranged to protrude from the surface of the guide plate 1 .

[0066] In the embodiment where the clamping block 2 is arranged on the outer circumference of the guide disk 1, the clamping block 2 is arranged away from the guide hole 11. The clamping block 2 can be arranged at various positions in the circumferential direction of the guide disk 1, and the arrangement is flexible.

[0067] In the process of materials passing through the guide plate 1 and entering the loading plate 3, the loading and unloading device will inevitably collide with the hole wall of the guide hole 11. After the hole wall is collided, the guiding effect of the material will inevitably be affected. In order to solve the above problem, this scheme adopts high-strength and collision-resistant materials to make the guide plate 1.

[0068] In some embodiments, the guide disk 1 is a metal disk.

[0069] The present solution also discloses a grinding machine, comprising a grinding mechanism, a material discharge guiding device and a carrier plate 3, wherein the grinding mechanism is used for grinding materials, and the material discharge guiding device is the material discharge guiding device recorded in any one of the above-mentioned solutions.

[0070] Since the material unloading guide device has the above-mentioned technical effects, the grinding machine having the material unloading guide device also has the same technical effects, which will not be described in detail here.

[0071] The material slides into the material hole 31 of the loading tray 3 through the guide hole 11 of the guide plate 1 of the material discharge guide device. In order to reduce damage to the material, a buffer strip 311 is provided in the material hole 31 of the loading tray 3 in this solution.

[0072] Optionally, a groove is provided on the hole wall of the material hole 31, and the buffer strip 311 is embedded in the groove.

[0073] The number and location of the buffer bars 311 are selected by those skilled in the art according to actual needs and are not specifically limited here.

[0074] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept.
