Please refer to Figure 6, the box body 70 is set on the machine table 10, and the box body 70 is hollow and has an accommodating space for accommodating the passivation device, cleaning device, transport device and temporary storage device to prevent external dust from entering In the accommodating space. In addition, the transport device can extend outside the box body 70 to transport the knives made elsewhere from the outside of the box body 70 to the box body 70 for cleaning, passivation and polishing, and transport the passivated and polished knives to the testing device 60 To be tested in. However, in other possible embodiments of the present creation, the passivation device may not have a cabinet.

Please refer to Figures 2 to 5 to illustrate the flow of the tool being transported by the transport device. When the tool 90 is made elsewhere, there may be cutting fluid remaining on the tool 90. The cutter 90 is immersed in the cleaning liquid in the first cleaning tank 31 of the cleaning device 30, as shown in FIG. 2, to wash away the cutting liquid on the cutter 90. Furthermore, since the cutting fluid may be mixed with grease and water and difficult to clean, the high-frequency oscillation generated by the vibrator 311 can be used to increase the cleaning effect of the cleaning fluid, and then the transport device 40 moves the tool 90 into the second The cleaning liquid in the cleaning tank 32 is cleaned twice, and then the high-speed airflow of the air jet is used to spray the cleaning liquid remaining on the cutter 90. Furthermore, since the finished tool 90 is cleaned before the cleaning liquid in the first cleaning tank 31, the cleaning liquid in the first cleaning tank 31 may have more grease, which can be removed by the first pipeline 3121 The cleaning liquid is sent to the oil-water separator 312 for oil-water separation. As shown in Figure 7, the cleaning liquid after the grease is removed is sent back to the first cleaning tank 31 through the second pipeline 3122 to avoid the cleaning liquid from containing too much grease. And reduce the cleaning effect of the cleaning liquid.

In view of the above, after the knife 90 is cleaned, the transport device 40 transports the knife 90 to the passivation device 20 for the holding and picking piece 223 to clamp the knife 90. Please refer to Figures 3, 8, and 9, because the passivation device 20 The clamping group has several holding parts 223, which can clamp several tools at the same time for subsequent passivation and polishing. After the clamping group completes the clamping of the tool 90, the lifting mechanism 211 drives the clamping group to move downward in the first direction to insert the tool 90 into the abrasive in the grinding groove 231, as shown in Figure 9, by The first power source 24 drives the rotating base 222 to rotate relative to the grinding unit, thereby driving the several holding and taking parts 223 on the rotating base 222 to move in a circular motion around a center. In addition, the second power source 25 drives the link 251 to make the link 251 drives the several holding and taking parts 223 to rotate relative to the rotating seat 222, whereby the several cutters 90 clamped by the clamping group can not only rotate individually in the abrasive, but can also revolve around a center together, thereby making the cutter 90 It can be in full contact with abrasives and has a better passivation polishing effect.

In view of the above, when the tool finishes passivation and polishing, the lifting mechanism drives the clamping group to move upwards in the first direction to move the tool upwards away from the abrasive. The cleaning device 30 shown in Figure 2 immerses the tool 90 in the cleaning liquid in the second cleaning tank 32 to wash away the abrasive that may be attached to the tool 90. After the cleaning is completed, the air jet 33 is used to spray the remaining on the tool 90 Then, the transport device 40 transports the tool 90 to the temporary storage device 50, as shown in FIG. 4, and inserts the tool 90 into the tool holder 52 for temporary storage for subsequent inspection.

Finally, when the tool 90 is to be inspected, the transport device 40 clamps the tool 90 from the temporary storage device 50, and transports the tool 90 to the measuring device 60, as shown in Figure 5, and places the tool on the placement seat. For size or contour detection.

However, the order in which the tool is transported by the transport device is only an example of this creation, and the user can change it as required. For example, after the tool is made and cleaned, the transport device will first insert the tool into the temporary storage device. When the passivation device is ready, the tool is moved from the temporary storage device to the passivation device for passivation and polishing.

In the above-mentioned embodiment, the upright of the passivation device has a lifting mechanism to drive the support base to drive the rotating base to lift, so that the several holding and taking parts inserted on the rotating base are raised and lowered at the same time. In other possible embodiments of the present invention , Several holding and picking parts may be changed to separate lifting, for example, the passivation device may be changed to have several lifting mechanisms, and several lifting mechanisms are changed to be installed on the rotating seat, and each lifting mechanism is connected to a holding and picking In other words, it is also a feasible implementation to make one lifting mechanism control the lifting of one holding and taking part, so that each holding and taking part can be lifted and lowered separately.

In the above embodiment, the lifting mechanism of the passivation device is connected to the clamping group to drive the clamping group to move closer to or away from the grinding groove in the first direction. In other possible embodiments of the present invention, the passivation device may be changed to lift The mechanism is connected to the grinding groove to drive the grinding groove to move closer to or away from the clamping group in the first direction, and still has a similar use effect as the above-mentioned embodiment.

In the above embodiment, the first power source of the passivation device is connected to the rotating seat to drive the rotating seat to rotate relative to the grinding unit. In other possible embodiments of the present invention, the first power source may be connected to the grinding groove to drive the grinding groove Rotating relative to the rotating base still has a similar use effect as the above-mentioned embodiment.

In the above-mentioned embodiment, the passivation device has a second power source, and the second power source is connected to a plurality of holding and taking parts through the linkage, so that the second power source drives the holding and taking parts to rotate relative to the rotating base. In other possible embodiments, the number of second power sources may be multiple, and the second power source is changed to be directly set on the holding and picking part without a linkage, in other words, one second power source controls one holding and picking part Rotation can still make the several holding and taking parts rotate relative to the rotating base, and it has a similar use effect as the above-mentioned embodiment.

In summary, the passivation equipment provided by this creation can transport tools between the passivation device and the cleaning device to automatically clean and passivate the tools, which can save labor costs and increase work efficiency, which is what the industry hopes for. In addition, the first cleaning tank of the cleaning device has a vibrator to increase the cleaning effect of the cleaning liquid on the tool, and the first cleaning tank is also connected to an oil-water separator to recover the grease in the cleaning liquid to prevent the grease from affecting the cleaning effect. The cleaning device further has an air jet to spray the cleaning liquid remaining on the tool. However, the above embodiments are only to illustrate and illustrate the technical content of this creation, and the patent scope of this patent shall be subject to the scope of the patent application described later.
