Description

Technical Field

[0002] Vacuum evaporation is a processing method in which a material is heated and evaporated under vacuum conditions, and the evaporated particle stream is directly directed onto the object to be processed to deposit a solid thin film on the object.

[0003] In existing technologies, when coating the surface of metal workpieces, the metal is first cleaned, and then the cleaned and dried workpieces are hung or installed in vacuum evaporation equipment. When small hardware parts are vacuum coated, due to their relatively small size, they need to come into frequent contact with the operator when hanging on the workpiece rack. This can easily cause a layer of contaminants to adhere to the surface of the hardware parts, affecting the quality of the coating during vacuum evaporation. Furthermore, since a large number of hardware parts are coated at one time, it is inconvenient to clean them. Summary of the Invention

[0020] A method for pretreating the surface of a workpiece for vacuum evaporation deposition, wherein the method is applied to the aforementioned workpiece surface pretreating apparatus for vacuum evaporation deposition, includes the following steps:

[0021] Step 1: Set the installation pipe vertically in the loading area, and hang the metal connecting parts to be coated on the hanging rings at the lower end of several support wheels. After the hanging is completed, push it to one side of the movable inner cylinder by the moving cart.

[0022] Step 2: Remove the installation tube from the mobile trolley and install it between the two bearing seats on one side. When the upper and lower ends of the installation tube contact the installation rod, the installation rod is compressed into the spring groove under the action of the inclined surface of the installation rod. After the installation tube is inserted into the prism box, the installation rod pops out under the action of the spring force of the installation spring, thus limiting the installation of the installation tube.

[0023] Step 3: After the vertical installation of the pipe is completed, connect the movable column to the self-rotating pin using splicing bolts;

[0024] Step 4: After all the mounting tubes are installed, the rotating shaft drives the central rotating table to rotate. The central rotating table drives several cantilevered plates to rotate synchronously. Then, the bearing seat rotates under the action of the teeth. When the bearing seat rotates, the mounting tube rotates synchronously. One side of several hanging rods contacts the bristles of several horizontal plates to complete the surface brushing treatment.

[0025] Step 5: When the central rotating platform and the cantilevered plate rotate, the bearing seat pulls the self-rotating seat to rotate along the travel groove. After the support wheel contacts the lower end of the travel groove, the support wheel rotates and travels. Then, the eccentrically set connecting rod drives the traction swing arm and the movable block connected by the connecting ear to move up and down reciprocally. Then, the self-rotating pin drives the movable column to move up and down. When the movable column moves up and down, it cooperates with several reciprocating plates and reciprocating teeth to move the reciprocating gears of several hanging rods to rotate back and forth. Several hardware connecting accessories to be coated and brush bristles are further fully contacted on one side of the hanging rod.

[0026] Step Six: When the metal connecting parts to be coated on the hanging rod come into contact with the brush bristles, the suction groove inside the cleaning plate is used for suction treatment, and the pollutants brushed off are sucked and collected from the suction groove.

[0027] Step 7: When the movable inner cylinder is coated, the motor drives the bevel gear ring to rotate, which in turn controls several control screws to rotate, pulling one side of the central rotating platform of the sliding seat box to slide. When the sliding seat moves, the rotating gear seat meshes with the teeth of the conversion gear, controlling the cleaning plate to rotate. When the cleaning plate is above the central rotating platform, the arc-shaped structures of several cleaning plates are arranged opposite each other, and the several cleaning plates are combined to form a cylinder.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] By utilizing the traditional rotatable structure of the material rack, and adding reciprocating moving components and cleaning components, while the mounting tube rotates normally, it drives the internal moving column to move up and down reciprocally, thereby driving several hanging rods to rotate back and forth. This ensures that the hardware accessories connected to the hanging rods make full contact with the cleaning components, performing surface pretreatment before final coating, thus improving coating quality. Furthermore, the overall device design is reasonable, the combination and installation of the mounting tubes are optimized, and the operation is simple and convenient. Attached Figure Description

[0048] Please see the appendix Figure 1-16 This application provides the following five preferred embodiments.

[0049] Example 1

[0050] according to Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10A workpiece surface pretreatment device for vacuum evaporation includes a movable inner cylinder 1, which is movably disposed on one side of an evaporation machine. A second traveling platform 201 and a first traveling platform 2 are horizontally disposed at both the upper and lower ends of the movable inner cylinder 1. A central rotating platform 3 is movably disposed on one side of both the first traveling platform 2 and the second traveling platform 201 via a rotating assembly. The rotating assembly includes a mounting base 4 and a rotating shaft 5. The pretreatment assembly includes several cleaning uprights 13, which are movably disposed between two rotating shafts 5 via two conversion assemblies. The conversion assemblies include cantilevered pull plates 6 and rotating gear seats 11. Two mounting bases 4 are respectively disposed at the upper and lower ends of the movable inner cylinder 1. A rotating shaft 5 is vertically disposed within each mounting base 4. The upper end of the rotating shaft 5 is connected to the center of the lower end of the central rotating platform 3. Several cantilevered pull plates 6 are horizontally symmetrically disposed outside the central rotating platform 3. A switching groove is provided through one side of each cantilevered pull plate 6. A control frame 7 is provided at the lower end of one side of the switching slot. The control frame 7 is U-shaped. A control screw 8 is horizontally inserted into the control frame 7 through a bearing. A sliding seat 10 is movably sleeved on the control screw 8 through a screw thread sleeve. A drive platform is provided at the upper end of the mounting base 4. A drive bevel gear ring 9 is movably sleeved at the lower end of the central rotating platform 3.

Several cleaning plates 13 are vertically provided on the upper end of several rotating tooth seats 11 and are arc-shaped.

[0051] The arc-shaped structure of the cleaning plate 13 prevents the support wheel 19 from colliding with the mounting tube 25 when it rotates. Furthermore, the arc-shaped structure of several cleaning plates 13 can be combined into a cylinder when they are not in use for cleaning.

[0052] The movement of the sliding seat 10 is controlled by the rotation of the control screw 8 of the bevel gear. When the rotating shaft 5 drives the central rotating table 3 to rotate, it drives the bevel gear ring 9 to rotate synchronously with the bevel gear and the central rotating table 3. When it is necessary to control the movement of several sliding seats 10, the existing technology commonly uses a motor to drive the bevel gear ring 9 to rotate, which can complete the synchronous rotation of several sliding seats 10 and realize the opening of several cleaning uprights 13 or their combination into a cylinder.

[0053] according to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8The workpiece surface pretreatment device for vacuum evaporation disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1.

[0055] The two sides of the rotating seat 18 are fitted to the two sides of the traveling groove 15. The upper end of the rotating seat 18 is provided with a bearing frustum. The bearing frustum is inserted into the rotating groove of the bearing seat 14 through the bearing rotation. When the bearing seat 14 rotates due to the meshing of the actuating teeth 16 and the actuating ring 17, 18a slides in the traveling groove 15. In addition, the outer circumferential surface of the support wheel 19 is provided with anti-slip texture.

[0059] according to Figure 1 , Figure 3 , Figure 11 and Figure 12The workpiece surface pretreatment device for vacuum evaporation disclosed in Embodiment 5 of this invention has a structure that is basically the same as that in Embodiment 4, except that: for the surface cleaning pretreatment of the metal parts to be processed connected by the hanging rods 29, the cleaning component is located on one side of the cleaning upright plate 13. The cleaning component includes several horizontal plates 33, and the several horizontal plates 33 are staggered with the several hanging rods 29. The several horizontal plates 33 are respectively horizontally and symmetrically arranged on one side of the arc-shaped structure of the cleaning upright plate 13. During the pretreatment operation, the arc-shaped structure side of the cleaning upright plate 13 faces the mounting tube 25, and several bristles 34 are respectively arranged on the side of the mounting tube 25. On the opposite side of the two adjacent horizontal plates 33, during the coating operation, several cleaning upright plates 13 are movably placed on one side of the central rotating table 3. The several cleaning upright plates 13 are combined to form a sealed cylinder. Both sides of the cleaning upright plate 13 are vertically provided with suction grooves 35. One side of the suction groove 35 is provided with a suction groove 36 that passes through one side of the cleaning upright plate 13.

[0061] The material of the bristles (34) can be customized according to the material of the parts being processed.

[0062] After the pretreatment cleaning before coating, the movable inner cylinder 1 rotates into the coating machine to complete the vacuum suction and vacuum evaporation treatment.

[0063] A method for surface pretreatment of workpieces for vacuum evaporation:

[0064] The mounting tube 25 is vertically set in the feeding area. The metal fittings to be coated are hung on the hanging rings at the lower ends of several support wheels 19. After hanging, to prevent personnel from contaminating the metal fittings during installation and affecting the coating quality, the mounting tube 25 is pushed to one side of the movable inner cylinder 1 by a mobile cart. It is then removed from the mobile cart and installed between two bearing seats 14 on one side. When the upper and lower ends of the mounting tube 25 contact the mounting rod 40, the mounting rod 40 is compressed into the spring groove under the action of the inclined surface of the mounting rod 40. After the mounting tube 25 is inserted into the prismatic box 24, the mounting rod 40 is then installed in the spring groove. 41. The spring pops out under the action of elastic force, limiting the installation of the mounting tube 25. After the vertical installation of the mounting tube 25 is completed, the movable column 26 is connected to the self-rotating pin 23 by the splicing bolt 27. After all the mounting tubes 25 are installed, the rotating shaft 5 drives the central rotating table 3 to rotate. The central rotating table 3 drives several cantilevered plates 6 to rotate synchronously. Then, the bearing seat 14 rotates under the action of the actuating teeth 16. When the bearing seat 14 rotates, the mounting tube 25 rotates synchronously. One side of several hanging rods 29 contacts the bristles 34 of several horizontal plates 33 respectively. After the surface brushing treatment is completed, when the central rotating table 3 and the cantilevered plate 6 rotate, the bearing seat 14 pulls the self-rotating seat 18 to rotate along the traveling groove 15. After the support wheel 19 contacts the lower end of the traveling groove 15, the support wheel 19 rotates. Then, the eccentrically set connecting rod 20 drives the traction swing arm 22 and the movable block 21 connected by the connecting ear to move up and down reciprocally. Then, the self-rotating pin 23 drives the movable column 26 to move up and down. When the movable column 26 moves up and down, it cooperates with several reciprocating plates 31 and reciprocating teeth 32 to move the reciprocating gears 30 of several hanging rods 29 to rotate reciprocally. One side of the hanging rod 29 Several metal connectors to be coated are further in full contact with the brush bristles 34. When several metal connectors to be coated are in contact with the brush bristles 34, the suction groove 35 in the cleaning plate 13 performs suction treatment, and the pollutants brushed off are sucked and collected from the suction groove 36. When the movable inner cylinder 1 is coated, the motor drives the bevel gear ring 9 to rotate, and the bevel gear ring 9 controls several control screws 8 to rotate, pulling the sliding seat 10 to slide to one side of the central rotating platform 3. When the sliding seat 10 moves, the rotating tooth seat 11 meshes with the teeth of the conversion tooth 12, controlling the cleaning plate 13 to rotate. When the cleaning plate 13 is above the central rotating platform 3, the arc structure of several cleaning plates 13 is set opposite to each other, and the several cleaning plates 13 are combined into a cylinder to avoid wasting coating material during vacuum coating.

[0065] When the rotating toothed seat 11 passes the conversion tooth 12, the cleaning upright plate 13 and the horizontal plate 33 have completed rotation.

A method for pretreating the surface of a workpiece for vacuum evaporation deposition, characterized in that: The workpiece surface pretreatment method for vacuum evaporation is applied to the workpiece surface pretreatment apparatus for vacuum evaporation as described in any one of claims 1-8, and includes the following steps: Step 1: Set the installation pipe (25) vertically in the loading area, and hang the metal connection accessories to be coated on the hanging rings at the lower end of several support wheels (19). After the hanging is completed, push it to one side of the movable inner cylinder (1) by the moving cart. Step 2: Remove the installation tube (25) from the mobile trolley and install it between the two bearing seats (14) on one side. When the upper and lower ends of the installation tube (25) contact the installation rod (40), the installation rod (40) is compressed into the spring groove under the action of the inclined surface of the installation rod (40). After the installation tube (25) is inserted into the prism box (24), the installation rod (40) pops out under the elastic force of the installation spring (41) to limit the installation of the installation tube (25).
