[0043] refer to Figure 4 , Figure 4 This invention provides a perspective view of the wiping device 5 in a sheet metal cover mounting production line 1 for a linear motor stator.

[0044] In some embodiments, reference Figure 4 and Figure 1 The wiping device 5 includes a wiping section production line 50, a second gantry 51, a second linear guide rail 52, and a second servo Z-axis module 53. The wiping section production line 50 extends along a first direction and is correspondingly arranged with the test section production line 40.

[0045] For example, the wiping device 5, through the cooperation of a gantry, linear guide rail and servo Z-axis module, reduces manual operation and labor intensity, while avoiding inconsistencies and potential contamination caused by manual wiping.

[0046] In some embodiments, reference Figure 1 and Figure 2 The wiping assembly 56 includes a magnetic felt plate, a cloth tape reel, a waste reel, a drip needle, a needle mounting base, a liquid reservoir, and multiple adjusting bearings. The magnetic felt plate is located at the bottom of the first fixed plate 55, and the cloth tape reel and waste reel are both located above the magnetic felt plate and spaced apart along a first direction. The cloth tape reel is wound with a cleanroom cloth tape, which passes under the magnetic felt plate and is wound around the waste reel to form a waste roll.

[0047] Above the magnetic felt plate, there are needle mounting seats at intervals. Each needle mounting seat has a drip needle extending in a third direction. The bottom of the drip needle corresponds to the magnetic felt plate, and the top is connected to a liquid storage syringe tube. This allows the wiping liquid from the liquid storage syringe to drip into the magnetic felt plate, wetting the cleanroom cloth at the bottom for wiping. Multiple adjusting bearings are respectively positioned along the path of the cleanroom cloth to tighten it.

[0048] For example, the wiping assembly 56 uses multiple adjusting bearings to press the cleanroom cloth belt, ensuring the stability and consistency of the belt during wiping. The wiping assembly 56 uses a dispensing needle to drip wiping liquid into the magnetic felt plate, wetting the cleanroom cloth belt for wiping, thus combining wet and dry wiping. This design can more efficiently remove stains from the magnetic plate surface while avoiding secondary contamination.

The pressure holding module 77 is slidably mounted on the top of the cover-applying section production line 70, and is used to move to the fourth positioning table 74 and press downward after the sheet metal cover is placed on the fourth positioning table 74, so that the sheet metal cover is tightly attached to the magnet.

[0056] For example, through the fourth linear guide rail 72 and the fourth servo Z-axis module 73, the adsorption assembly can achieve high-precision gripping and placement of sheet metal covers, significantly improving the flexibility and positioning accuracy of the equipment. The sheet metal cover hopper 75 stacks multiple sheet metal covers along a third direction, reducing production interruptions caused by frequent refills while ensuring the hopper's cleanliness and orderliness.

[0060] For example, the sensor can move in multiple directions via the fifth linear guide 83 and the fifth servo Z-axis module 84 to ensure accurate alignment of the measurement position. A laser displacement sensor is used for height detection. The high precision and fast response characteristics of the laser sensor enable non-contact measurement, avoiding errors and damage that may be caused by physical contact.
