Description

PVD loading and unloading equipment index shaft vertical position compensation device

[0001] The present invention relates to a shaft vertical position compensation device in a PVD loading and unloading equipment index, and more particularly, to a vertical position compensation device that enables safe transportation of carbide insert products and spacers through accurate gripping movements of a transfer gripper by vertically positioning a loading and unloading shaft for PVD coating.

[0002] In general, cutting tools are mainly used for cutting ferrous, non-ferrous metals, and non-metallic materials. They are tools that are usually installed on machine tools and perform cutting to process the workpiece into a desired shape.

[0003] Carbide insert products used in cutting tools are sintered alloys formed by mixing diamond powder or carbide powder with metal powders such as iron (Fe), tungsten (W), cobalt (Co), copper (Cu), nickel (Ni), tin (Sn), copper-tin (Cu-Sn), zinc (Zn), copper-zinc (Cu-Zn), and silver (Ag).

[0004] The molding step prior to sintering involves placing a mixed powder in a rectangular cavity and performing a primary pressurized molding. The primary pressurized mixture is then placed in the cavity of a carbon mold, and a puncher is used to apply relatively high pressure to form a cutting tip having a shape corresponding to the shape of the puncher. By sintering the insert tip formed into a certain shape in a sintering furnace, a diamond insert tip or insert tip is completed.

[0005] The sintered carbide insert must go through an inspection stage and a PVD (Physical Vapor Deposition) coating stage to become a finished product. The carbide insert product is loaded onto a shaft for PVD coating along with a spacer for coating, or after the coating stage is completed, the carbide insert and spacer are separated (loading and unloading operations).

[0006] The shaft is placed in a tilted state on the index of the loading and unloading equipment for PVD coating and is vertically positioned to perform loading and unloading operations. However, since the shaft has a different outer diameter depending on the specifications of the product, it is difficult to maintain an accurate vertical state, which causes a gripping error of the transfer gripper, and there is a problem that this causes surface damage to the product and a falling accident inside the main body equipment.

[0007] As described above, the applicant has developed a shaft vertical position compensation device within the PVD loading and unloading equipment index to maintain the exact vertical position of the shaft during loading and unloading operations, thereby preventing surface damage to the product due to the exact gripping of the transfer gripper and accidents from falling within the main body of the equipment.

[0008] An object of the present invention to solve the above-described problem is to provide a compensation device for vertically positioning a shaft on which a carbide insert product is loaded or unloaded within an index of a PVD loading and unloading equipment.

[0009] Another object of the present invention is to provide a shaft vertical position correction device in a PVD loading unloading equipment index comprising a gripper unit and a transfer unit.

[0010] Another object of the present invention is to provide a shaft vertical positioning compensation device in a PVD loading unloading equipment index, wherein the gripper unit comprises a gripper and a gripper cylinder configured to vertically 'position' the shaft inclined in an inclined groove.

[0011] Another object of the present invention is to provide a shaft vertical position correction device in a PVD loading and unloading equipment index, wherein the gripper is configured to grip the upper end of the shaft that is tilted and placed in the inclined groove.

[0012] Another object of the present invention is to provide a shaft vertical position correction device in a PVD loading and unloading equipment index, wherein the gripper cylinder is configured to open and close left and right jaws so that the gripper can grip the shaft.

[0013] Another object of the present invention is to provide a shaft vertical position compensation device in a PVD loading unloading equipment index, wherein the transfer unit is configured to control the position of the gripper unit to maintain the shaft in a vertical state in the 'normal position'.

[0014] Another object of the present invention is to provide a shaft vertical position correction device within a PVD loading and unloading equipment index configured to 'control the position' by correcting the deviation of the outer diameter of the shaft by the position control robot.

[0015] Another object of the present invention is to provide a shaft vertical position correction device within a PVD loading unloading equipment index configured to vertically position a shaft placed in an inclined groove of an upper plate by calculating a stroke in which the position control robot reflects the outer diameter deviation data of the shaft applied to the loading and unloading operation input to the controller.

[0016] Within the index of the PVD loading and unloading equipment for achieving this purpose, a compensation device is provided for vertically positioning a shaft on which a carbide insert product is loaded or unloaded.

[0017] Another feature of the shaft vertical position correction device in the PVD loading unloading equipment index of the present invention is that it comprises a gripper unit and a transfer unit.

[0018] Another feature of the shaft vertical positioning compensation device in the PVD loading unloading equipment index of the present invention is that the gripper unit comprises a gripper and a gripper cylinder configured to vertically 'position' the shaft inclined in the inclined groove.

[0022] Another feature of the shaft vertical position correction device of the PVD loading unloading equipment index of the present invention is that the position control robot is configured to 'control the position' by correcting the deviation of the outer diameter of the shaft.

[0024] The vertical positioning compensation device of the present invention, as described above, is configured to first calculate a stroke that reflects shaft outer diameter deviation data and vertically position the shaft.

[0034] However, this is not intended to limit the present invention to specific embodiments, but is to be understood to include all modifications, equivalents and substitutes included in the spirit and technical scope of the present invention.

[0035] The terms and words used in this invention are used solely to describe specific embodiments and are not intended to limit the invention. Based on the principle that the concepts of terms can be appropriately defined to best explain the invention, they should be interpreted in a way that aligns with the technical spirit of the invention.

[0036] The applicant of the present invention applied for and received a patent for the invention, "Carbide insert loading and unloading device for PVD coating (Application No. 10-2016-0132548, Application Date 2016.10.13.)" (hereinafter referred to as "main device") in 2016. The invention relates to a device for loading a carbide insert product onto a shaft for PVD coating or separating a carbide insert product from a shaft after PVD coating is completed.

[0037] Referring to Fig. 1, the above main body equipment is briefly described. The above main body equipment is equipment that loads a carbide insert product onto a shaft for PVD coating (loading operation) or separates a carbide insert product that has been PVD coated from a shaft (unloading operation).

[0038] The above main body equipment comprises a frame, a pallet transport section, a spacer supply and retrieval section, a carbide insert supply and retrieval section, a loading and unloading section, a loading and unloading shaft grip section, a loading and unloading operation section, and a controller (not shown).

[0039] Among the configurations of the above main body equipment, regarding the present invention, the 'loading and unloading section' is examined. The loading and unloading section is formed as a cylindrical index (20) that is installed in a sunken portion of the frame and carries a plurality of shafts on which superhard insert products are loaded.

[0040] At this time, the index (20) is a cylindrical shape with a lower disc (220) formed large at the bottom and an upper disc (210) formed small at the top, and is a rotating body that can tilt and place a plurality of shafts (1.3) at equal intervals along an arc toward the center.

[0041] The index (20) of the above loading and unloading section is configured such that a plurality of inclined grooves (211) are installed at equal intervals on the upper plate (210) and a number of mounting grooves (221) equal to the inclined grooves (211) are installed on the lower large plate (220) in correspondence with each other so that the shaft (1.3) can be stably mounted.

[0042] As described above, in the loading and unloading process, the empty shaft (1.3) or the loaded shaft (1.3) within the index (20) must be vertically placed at the loading and unloading work position (fixed position) to load the carbide insert product onto the shaft (1.3) or to separate the loaded carbide insert product.

[0043] At this time, the shaft has various outer diameters depending on the specifications of the loaded carbide insert product. In the past, regardless of the outer diameter, the shaft was positioned by a uniform stroke of the gripper, which resulted in a decrease in vertical precision, and consequently, a decrease in the gripping accuracy of the transfer gripper, and as a result, there was a problem of a problem of a dropping accident occurring during transport due to surface damage and poor gripping of the carbide insert product.

[0044] In order to solve the above-described problem, the present applicant has developed a device for compensating for the deviation of different outer diameters of shafts, thereby precisely maintaining the vertical accuracy of the shaft, thereby developing a shaft vertical position compensation device within the PVD loading and unloading equipment index according to the present invention configured to enable the transfer gripper to grip accurately.

[0045] Specific features and advantages of the present invention will be further clarified by the following description with reference to the attached drawings.

[0046] FIG. 1 is a schematic perspective view of a main body equipment combined with a shaft vertical position correction device within a PVD loading unloading equipment index according to the present invention, FIG. 2 is a schematic perspective view showing a shaft vertical position correction device within a PVD loading unloading equipment index according to the present invention, FIG. 3 is a schematic front view, a plan view, and a side view of a shaft vertical position correction device within a PVD loading unloading equipment index according to the present invention, FIG. 4 is a drawing showing a shaft vertical position correction device within a PVD loading unloading equipment index combined with an index according to the present invention, FIG. 5 is a drawing showing a correction value required for the position according to the deviation of the outer diameter of the shaft according to the present invention, FIG. 6 is a drawing showing a shaft in a loading unloading state applied to the present invention, and FIG. 7 is a drawing showing a sequence for vertically preparing a shaft in the position by applying the present invention.

[0047] Hereinafter, the technical configuration of the shaft vertical position correction device in the PVD loading unloading equipment index according to the present invention will be described in detail with reference to FIGS. 2 to 4.

[0055] At this time, the shaft has different outer diameters (Ø1.5 to Ø4) depending on the specifications of the carbide insert product.

[0056] The shaft vertical position correction device in the PVD loading and unloading equipment index according to the present invention has the following characteristics.

[0057] First, the vertical position correction device of the present invention is configured to vertically position the shaft by calculating a stroke reflecting shaft outer diameter deviation data.
