[0034] The wax block position detection device 26 in this embodiment includes a wax block position detection swing shaft 261, a wax block position detection swing frame 262, a wax block position detection spring 263, a wax block position detection sensor 264, a wax block position detection sensing protrusion 265 and a wax block position detection sensor bracket 267. The wax block position detection swing shaft 261 is installed on the wax block lifting fixed seat 246, the wax block position detection swing frame 262 is installed on the wax block position detection swing shaft 261, the two ends of the wax block position detection spring 263 are respectively abutted against the vertical support plate 234 and the rear end of the wax block position detection swing frame 262, the front end of the wax block position detection swing frame 262 is provided with a wax block position detection sensing protrusion 265, the wax block position detection sensor bracket 267 is installed on the wax block lifting limit frame 245, the wax block position detection sensor 264 is installed on the wax block position detection sensor bracket 267, and the wax block position detection sensor 264 cooperates with the wax block position detection sensing protrusion 265.

[0035] The pallet position detection device 25 in this embodiment includes a pallet position detection rotating shaft 251, a pallet position detection sensor 252 and a pallet position detection sensing notch 253. The pallet position detection rotating shaft 251 and the pallet position detection sensor 252 are both installed on the wax block position detection swing frame 262. The pallet position detection rotating shaft 251 is provided with a pallet position detection sensing notch 253. The pallet position detection sensing notch 253 cooperates with the pallet position detection sensor 252. The pallet position detection rotating shaft 251 is located at the lower side of the wax block lifting limit frame 245.

[0036] The working method of the light cleaning machine in this embodiment is as follows: the light cleaning motor 12 drives the light cleaning shaft 14 to drive the light cleaning cloth wheel 13 to rotate, and the vertical moving motor 231 drives the vertical support plate 234 to move downward. When the support plate position detection rotating shaft 251 contacts the light cleaning cloth wheel 13, the support plate position detection rotating shaft 251 rotates. Since the rotation of the support plate position detection rotating shaft 251 will cause the support plate position detection sensor 252 to detect that the signal of the support plate position detection sensing notch 253 changes (that is, when the support plate position detection sensing notch 253 is aligned with the support plate position detection sensor 252, the support plate position detection sensor 252 has no signal, and the support plate position detection sensor The indicator light on the sensor 252 goes out, otherwise there is a signal from the pallet position detection sensor 252, and the indicator light on the pallet position detection sensor 252 lights up. As the pallet position detection rotating shaft 251 rotates, the indicator light on the pallet position detection sensor 252 will flicker). At this time, it means that the pallet position detection rotating shaft 251 is in contact with the cleaning cloth wheel 13. The vertical moving motor 231 is required to drive the vertical pallet 234 to move upward a certain distance (about 1.5 cm), and then the vertical moving motor 231 stops, so that the pallet position detection rotating shaft 251 is disengaged from the cleaning cloth wheel 13, thereby determining the position of the vertical pallet 234.

[0037] The wax block lifting motor 241 drives the wax block lifting bracket 244 to move downward, so that the wax block 3 moves downward along the wax block lifting limit frame 245. When the wax block 3 contacts the support plate position detection rotating shaft 251, the wax block position detection swing frame 262 will swing along the wax block position detection swing shaft 261, but the support plate position detection rotating shaft 251 and the cleaning cloth wheel 13 are in a non-contact state, thereby causing the wax block position detection sensing protrusion 265 to disengage from the wax block position detection sensor 264, so that the signal of the wax block position detection sensor 264 changes (that is, when the wax block position detection sensing protrusion 265 contacts the wax block position detection sensor 264 through the wax block position detection spring 263, the wax block position detection sensor 264 has a signal The indicator light of the wax block position detection sensor 264 is always on; on the contrary, when the wax block position detection sensing protrusion 265 is separated from the wax block position detection sensor 264, the wax block position detection sensor 264 has no signal, and the indicator light of the wax block position detection sensor 264 is off). At this time, the position of the wax block 3 can be detected, and the wax block lifting motor 241 drives the wax block lifting bracket 244 to continue to move downward for a certain distance (the distance is greater than 1.5 cm, usually 2-2.5 cm), after which the wax block lifting motor 241 stops, and the wax block 3 is tightened by the wax block tightening cylinder 247 and the wax block 3 is brought into contact with the cleaning cloth wheel 13, so that the cleaning cloth wheel 13 can be waxed by the wax block 3, and the workpiece can be waxed by the cleaning cloth wheel 13.

[0038] When the wax block 3 is used to wax the polishing cloth wheel 13, the horizontal support 224 is driven by the horizontal moving cylinder 221 to move back and forth horizontally along the horizontal moving guide rod 222 to ensure that the wax block 3 is evenly coated on the polishing cloth wheel 13, to avoid the wax block 3 being in contact with the polishing cloth wheel 13 for a long time at the same position, which will cause grooves to appear on the wax block 3.

[0039] The polishing machine can be installed one on each of the left and right sides of the sanding machine. When the robot holds the workpiece and polishes it with the sanding machine, the robot can hold the workpiece and place it on the polishing cloth wheel 13 of the polishing machine. The polishing machine can be used to polish the workpiece to make the surface of the workpiece smoother and more delicate.
