Description
Technical Field
[0001] This utility model relates to the field of workpiece pretreatment technology, specifically to a workpiece surface pretreatment device for a vacuum coating machine. Background Technology
[0002] Vacuum coating machine workpieces refer to various objects whose surfaces are coated using physical or chemical vapor deposition (PVD / CVD) processes in a vacuum environment. These include functional products such as optical lenses, electronic components, cutting tools, and decorative parts. However, workpieces require surface cleaning pretreatment before coating to improve the quality of the coating process.
[0003] Existing pretreatment devices typically use only simple water rinsing when cleaning milling cutter workpieces. This crude cleaning method has several drawbacks: First, the spiral grooves and cutting edges on common milling cutters are complex and difficult to be completely covered and cleaned by water, resulting in incomplete removal of cutting fluid residue and metal debris. Second, simple water rinsing cannot effectively remove the oxide layer and micro-contaminants on the tool surface. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-6 This utility model provides a technical solution:
[0026] A pretreatment device for the surface of a workpiece in a vacuum coating machine includes a cleaning shell 1. A fixed frame 3 is installed at one top end of the cleaning shell 1. A first cleaning component for physical cleaning pretreatment of the surface of a milling cutter workpiece is arranged at the top center and bottom of the fixed frame 3. The first cleaning component includes a second electric telescopic rod 4, a mounting base 5, and cleaning brushes 7. The second electric telescopic rod 4 is fixedly installed at the top center of the fixed frame 3, and the output end of the second electric telescopic rod 4, which passes through the bottom of the fixed frame 3, is fixed to the mounting base 5. Several sets of cleaning brushes 7 for physical cleaning of the surface of the milling cutter workpiece are installed at the bottom of the mounting base 5. The first cleaning component also includes a groove 6 and a retaining post 601. The groove 6 is opened at the bottom of the mounting base 5 and has several sets. The retaining post 601 is engaged inside the groove 6, and the bottom of the retaining post 601 is fixedly connected to the cleaning brushes 7. By setting the groove 6 and the retaining post 601, the cleaning brushes 7 can be easily disassembled and replaced.
[0027] The top two ends of the fixed frame 3 are equipped with a second cleaning assembly for chemical rinsing pretreatment of the surface of the milling cutter workpiece; the second cleaning assembly includes a water pump 8, a suction pipe 801, a cleaning fluid tank 802, a telescopic hose 803, a pipe connector 804, an installation pipe 9, and a high-pressure nozzle 901. The water pump 8 is fixedly installed at both ends of the front of the top of the fixed frame 3, and a suction pipe 801 is threaded on one side of the water pump 8. One end of the suction pipe 801 is connected to the inside of the cleaning fluid tank 802. A telescopic hose 803 is threaded on the other side of the water pump 8. A pipe connector 804 is fixed to one end of the telescopic hose 803. The pipe connector 804 is threadedly installed with the installation pipe 9. Several sets of high-pressure nozzles 901 are installed at the bottom of the installation pipe 9.
[0028] One end of the mounting tube 9 is fixedly installed at the center of one side of the mounting base 5.
[0029] This invention utilizes the coordinated operation of components such as a fixed frame 3, a second electric telescopic rod 4, a mounting base 5, a cleaning brush 7, a water pump 8, a suction pipe 801, a cleaning fluid tank 802, a telescopic hose 803, a pipe joint 804, an installation pipe 9, and a high-pressure nozzle 901 to construct a dual-stage cleaning pretreatment device. The device uses the cleaning brush 7, driven by the second electric telescopic rod 4, to physically scrub complex structures such as spiral grooves on the milling cutter workpiece. Simultaneously, the high-pressure nozzle 901 sprays cleaning fluid for chemical rinsing. This synergistic effect not only effectively removes cutting fluid residue and metal debris that are difficult to handle using traditional methods, but also deeply removes surface oxide layers and microscopic contaminants.
[0030] The cleaning housing 1 has a first electric telescopic rod 2 installed at both ends on one side of the upper part. The front and back of the top of the cleaning housing 1 are provided with a moving groove 201. The output end of the first electric telescopic rod 2, which passes through the moving groove 201, is fixed with a moving block 202. A fixing frame 3 is fixedly installed on the top of the moving block 202.
[0031] Furthermore, firstly, by operating the external controller, the first electric telescopic rod 2 is controlled to work, so that the first electric telescopic rod 2 drives the moving block 202 to move left and right in the moving groove 201, thereby facilitating the moving block 202 to drive the fixed frame 3 to move left and right on the top of the cleaning shell 1, so that the first cleaning component and the second cleaning component on the fixed frame 3 can work simultaneously, thereby improving the quality and effect of the pretreatment of the milling cutter workpiece surface.
[0032] Next, by controlling the output end of the second electric telescopic rod 4 to move up and down, the mounting base 5 is moved up and down, so that the several sets of cleaning brushes 7 set on the bottom of the mounting base 5 can contact the surface of the milling cutter workpiece, thus facilitating physical cleaning of its surface; at the same time, the water pump 8 starts working, so that the suction pipe 801 on it draws the cleaning liquid inside the cleaning liquid tank 802, and discharges it into the mounting pipe 9 through the telescopic hose 803. Finally, the several sets of high-pressure nozzles 901 set at the bottom of the mounting pipe 9 spray and rinse the milling cutter workpieces inside the several sets of milling cutter workpiece placement slots on the top of the card seat 15.
[0033] The combined effect of these two methods not only effectively removes cutting fluid residue and metal shavings that are difficult to handle using traditional methods, but also deeply removes surface oxide layers and microscopic contaminants.
[0034] The first electric telescopic rod 2 and the second electric telescopic rod 4 used in this utility model are industrial-grade linear actuators. Typical parameters include: stroke 50-200mm (adapting to different sizes of milling cutters), thrust 200-500N (ensuring effective pressure on the cleaning brush 7), speed 10-30mm / s (adjustable cleaning rhythm), and repeatability accuracy ±0.05mm (ensuring brushing stability).
[0035] Furthermore, the milling cutter workpiece placement groove provided on the top of the card holder 15 corresponds to the high-pressure nozzle 901 and the cleaning brush 7.
[0036] The cleaning housing 1 has a cleaning cavity 102 at the top center. The cleaning cavity 102 has grooves 103 on both sides of the top. The grooves 103 mainly allow the first cleaning component and the second cleaning component on the fixing frame 3 to move to the periphery, making it convenient to remove the placement seat 11. The placement seat 11 is provided on the upper part of the cleaning cavity 102, and the placement seat 11 is located below the grooves 103.
[0037] Support blocks 10 are fixed at both ends of the side walls on the front and back sides of the inner cavity 102. A placement seat 11 is placed on the top of the support block 10. A base 13 is fixed at the center of the inner bottom of the placement seat 11. A clamping seat 15 for clamping and placing milling cutter workpieces is installed on the top of the base 13. Several sets of milling cutter workpiece placement grooves are opened on the top surface of the clamping seat 15.
[0038] By providing a support block 10, it is easy to place the placement seat 11 directly onto it, thereby facilitating the quick removal of the placement seat 11 from the cleaning cavity 102.
[0039] Lifting rods 12 are fixed to both ends of the top of the placement base 11. Fixing grooves 14 are provided at both ends of the top of the base 13. Fixing blocks 1401 are engaged inside the fixing grooves 14, and card holders 15 are fixedly installed on the top of the fixing blocks 1401. By providing the fixing grooves 14 and fixing blocks 1401, it is easy to replace card holders 15 of different sizes, thereby improving the applicability of the milling cutter to the workpiece. Several sets of filter screens are provided at both ends of the inner bottom of the placement base 11. This facilitates the filtering and blocking of debris washed from the surface of the milling cutter, preventing blockage during drainage. A drain pipe 101 is installed at the center of the lower side of one side of the cleaning shell 1.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
