[0014] Preferably, the guide groove is in the shape of a chevron, and the guide groove is located above the placing platform and the ultrasonic cleaner. Compared with the prior art, the present application provides a full-automatic PVD vacuum coating workpiece ultrasonic cleaning device, which has the following advantages: 1. The full-automatic PVD vacuum coating workpiece ultrasonic cleaning device can drive the lifting mechanism and the placing mechanism to reciprocally move left and right and up and down through the cooperation between the reciprocating screw rod, the moving seat, the guide groove and the limiting rod, which realizes the slow placement of the coating workpiece into the ultrasonic cleaner for cleaning during the reciprocating movement left and right and up and down, avoids the problem of uneven placement speed of the coating workpiece, which easily causes the breakage of the coating on the surface of the workpiece, and further improves the operability of the coating workpiece cleaning.

This fully automatic ultrasonic cleaning device for PVD vacuum coated workpieces, through the cooperation of the connecting frame, rotating gear, mounting frame, and cleaning frame, can limit the coated workpiece to be placed into the ultrasonic cleaner for cleaning. The rotating gear, driven by the connecting shaft, rotates, causing the coated workpiece in the cleaning frame to change position under its own gravity.

[0017] The parts not covered in this device are the same as or can be implemented using existing technologies. During the reciprocating left-right and up-down movement, the coated workpiece is slowly placed into the ultrasonic cleaner for cleaning, avoiding the problem of uneven placement speed of the coated workpiece which can easily cause damage to the coating on the workpiece surface. At the same time, the contact surface between the coated workpiece and the cleaning frame is not unique, which further improves the operability of cleaning the coated workpiece.

[0022] In one embodiment, with reference to Figures 1-9The utility model provides an automatic PVD vacuum coating workpiece ultrasonic cleaning device, including the worktable 1 of Z, still include: the placement platform 2 and ultrasonic cleaning machine 3 fixed in the bottom wall of Z type worktable 1 respectively, the inside fixed connection of ultrasonic cleaning machine 3 has helical gear 31, reciprocating screw rod 4 is rotated in the top wall of Z type worktable 1 through drive part, the surface screw connection of reciprocating screw rod 4 has moving seat 5, the bottom fixed connection of moving seat 5 has lifting mechanism 6, the bottom fixed connection of lifting mechanism 6 has placement mechanism 7, the guide groove 8 of being opened in the inner wall of Z type worktable 1, the inside sliding connection of guide groove 8 has limit rod 9, limit rod 9 is fixedly connected with the back of lifting mechanism 6, the inner top wall of Z type worktable 1 is fixedly connected with guide rod 41, the surface sliding connection of moving seat 5 and guide rod 41, the shape of guide groove 8 is herringbone, and guide groove 8 is located above placement platform 2 and ultrasonic cleaning machine 3.

[0023] Adopt such scheme, through reciprocating screw rod 4 drive moving seat 5 and move, can drive lifting mechanism 6 and placement mechanism 7 synchronous displacement leftmost, under the arrangement of placement mechanism 7, can be used to store coating workpiece, then through the guide groove 8 opening, can be used to guide sliding limit rod 9, since limit rod 9 is fixed in the side wall of lifting mechanism 6, therefore can lifting mechanism 6 slowly carry out up and down adjustment, in the up and down adjustment process of lifting mechanism 6, can synchronous drive coating workpiece in placement mechanism 7 slowly put into ultrasonic cleaning machine 3, so can ensure that every part on the surface of coating workpiece can fully contact cleaning fluid, and ultrasonic vibration can uniformly act on workpiece surface, this helps more thoroughly remove dirt and impurities on the surface of workpiece, improves cleaning quality.

[0024] Specific work, first through the setting of Z type worktable 1 top placement platform 2, can place the coating workpiece to be cleaned in placement mechanism 7, then drive reciprocating screw rod 4 through the drive part above placement platform 2, drive moving seat 5 to displace under reciprocating screw rod 4, synchronous drive lifting mechanism 6 and placement mechanism 7 to displace in the displacement process of moving seat 5, can guide limit rod 9 under the opening of guide groove 8, since limit rod 9 is fixed on the surface of lifting mechanism 6, synchronous drive lifting mechanism 6 to guide limit, when the fixed limit rod 9 of lifting mechanism 6 follows the sliding in guide groove 8, can slowly adjust the spacing of lifting mechanism 6, so can slowly put the coating workpiece into ultrasonic cleaning machine 3, then start ultrasonic cleaning machine 3 to ultrasonic cleaning coating workpiece in ultrasonic cleaning machine 3, under the setting of guide rod 41, can guide and limit when moving seat 5 displaces, so as to ensure the stability of moving seat 5 displacement, can automatically drive moving seat 5 to reciprocate under the drive of reciprocating screw rod 4, so reciprocating to replace the cleaning work of different coating workpieces.

[0025] It is to be further explained that the driving member is a servo motor.

[0026] In one embodiment, referring to Figure 3 , the lifting mechanism 6 comprises a piston rod 61 fixed at the bottom of the moving base 5, the surface of the piston rod 61 is slidingly connected with a piston cylinder 62, the piston cylinder 62 is fixedly connected with the end of the limiting rod 9, the top of the piston cylinder 62 is fixedly connected with a fixed plate 63, and the surface of the fixed plate 63 is provided with a processing assembly 64.

[0027] With such a scheme, the fixed plate 63 can be driven to adjust the up-down distance under the sliding of the piston cylinder 62 on the surface of the piston rod 61, and since the placing mechanism 7 is fixed at the bottom of the fixed plate 63, the placing mechanism 7 can be simultaneously driven to adjust the up-down distance to enter the inside of the ultrasonic cleaner 3 to perform cleaning work.

[0028] In specific work, the piston rod 61 is fixed at the bottom of the moving base 5, so the piston rod 61 is fixed and limited, then the piston cylinder 62 is slid on the surface of the piston rod 61, the fixed plate 63 is fixed at the bottom of the piston cylinder 62, and the limiting rod 9 is fixed with the sidewall of the piston cylinder 62, since the limiting rod 9 slides in the guide groove 8, when the moving base 5 drives the piston rod 61 to displace, the piston rod 61 will synchronously drive the piston cylinder 62 to displace, at this time, the piston cylinder 62 will drive the limiting rod 9 to slide in the guide groove 8, since the guide groove 8 is in a herringbone shape, it will slide from bottom to top and from top to bottom, thus driving the piston cylinder 62 to adjust the up-down distance along the surface of the piston rod 61, and the placing mechanism 7 is synchronously adjusted to adjust the up-down distance during the up-down adjustment of the piston cylinder 62.

[0029] In one embodiment, referring to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the placing mechanism 7 comprises a connecting frame 71 rotating on the bottom of the fixed plate 63 through a rotating shaft, the inside of the connecting frame 71 is slidingly connected with a rotating toothed disc 72, the inside of the rotating toothed disc 72 is fixedly connected with a mounting frame 73, the inside of the mounting frame 73 is slidingly connected with a cleaning frame 74, the inside of the connecting frame 71 is rotatably connected with a connecting shaft 75 through a bearing, the surface of the connecting shaft 75 is fixedly connected with a driven gear 76 and a driving gear 77 respectively, the surface of the driven gear 76 is meshingly connected with the rotating toothed disc 72, the end of the connecting shaft 75 is fixedly connected with a rotating disc 78, the surface of the rotating disc 78 is rotatably connected with a linkage rod 79 through a rotating shaft, the linkage rod 79 is rotatably connected with the bottom of the fixed plate 63 through a rotating shaft, and one side of the cleaning frame 74 is provided with a lock catch 741 which is snapingly connected with the mounting frame 73.

[0030] With such a scheme, under the arrangement of the mounting frame 73 and the cleaning frame 74 included in the placing mechanism 7, the plated workpieces can be placed through the cleaning frame 74, and different capacity spaces can be classified according to the sizes of the plated workpieces, so as to avoid collision between the plated workpieces during cleaning.

[0031] In specific work, the plated workpieces to be cleaned can be carried through the cleaning frame 74, and then the cleaning frame 74 is mounted in the mounting frame 73, and the mounting frame 73 and the cleaning frame 74 are locked through the cleaning frame 74 to ensure the firmness between the mounting frame 73 and the cleaning frame 74. The mounting frame 73 is driven to displace synchronously with the connecting frame 71 under the movement of the fixed plate 63, and the mounting frame 73 is driven to displace synchronously with the rotating tooth disc 72 under the driving of the connecting frame 71, so as to slowly place the mounting frame 73 and the cleaning frame 74 in the ultrasonic cleaner 3 for cleaning work. The driven gear 76 is driven to rotate synchronously under the driving of the connecting shaft 75, the rotating tooth disc 72 is driven to rotate synchronously under the rotation of the driven gear 76, the mounting frame 73 and the cleaning frame 74 are driven to rotate synchronously under the rotation of the rotating tooth disc 72, and the plated workpieces are driven to rotate synchronously under the rotation of the cleaning frame 74. The plated workpieces can change under their own gravity under the rotation of the plated workpieces, so that the contact surface between the plated workpieces and the cleaning frame 74 is not unique, the problem that the local contact surface of the plated workpieces leads to poor cleaning effect is avoided, and the cleaning dead angle is further effectively reduced. At the same time, the rotating disc 78 is driven to rotate under the rotation of the connecting shaft 75, and the linkage rod 79 is driven to rotate under the driving of the rotating disc 78. Since the connecting frame 71 and the fixed plate 63 are connected through the rotating shaft, the connecting frame 71 and the fixed plate 63 are oriented to rotate along the rotating shaft under the stroke change of the linkage rod 79, so as to change the angle of the connecting frame 71. The angle of the connecting frame 71 is changed, the rotating tooth disc 72, the mounting frame 73 and the cleaning frame 74 are driven to change the pitch angle synchronously, so as to clean the internal plated workpieces more cleanly. When the connecting frame 71 enters the ultrasonic cleaner 3, the main gear 77 fixed at the end of the connecting shaft 75 is engaged with the surface of the inclined rack 31 under the stroke change of the linkage rod 79. The main gear 77 is driven to rotate along the surface of the inclined rack 31 under the continuous downward displacement of the connecting frame 71, so as to drive the connecting shaft 75 to rotate.

[0032] In one embodiment, referring to Figure 8 The processing assembly 64 includes fixed tubes 641 fixed on both sides of the fixed plate 63, air blowers 642 fixedly connected to the surfaces of the fixed tubes 641 through pipes, and air nozzles 643 fixedly connected to the surfaces of the air blowers 642 at equal distances.

[0033] With such a scheme, under the arrangement of the processing assembly 64, the ultrasonic cleaning machine 3 can be blown, and the small bubbles suspended in the ultrasonic cleaning machine 3 can be effectively eliminated by blowing, so as to avoid the influence of the residual small bubbles on the cleaning quality of the plated workpiece in the later stage.

[0034] In specific work, the gas in the contact sheet one 621 can be driven by the plastic spring 622 connected by the pipeline, and then the gas can be uniformly dispersed and sprayed out through the contact sheet two 623. When the contact sheet one 621 is located in the ultrasonic cleaning machine 3, the excess small bubbles in the ultrasonic cleaning machine 3 can be blown and eliminated. When the contact sheet one 621 is away from the ultrasonic cleaning machine 3, the gas can be sprayed on the surface of the plated workpiece in the cleaning frame 74, so as to dry the residual moisture on the surface of the cleaned plated workpiece, prevent the water from dropping and polluting the surrounding environment, and further improve the cleaning quality of the plated workpiece.

[0035] In one embodiment, referring to Figure 9 The inner bottom wall of the piston cylinder 62 is fixedly connected with the contact sheet one 621, the top of the contact sheet one 621 is fixedly connected with the plastic spring 622, the top of the plastic spring 622 is fixedly connected with the contact sheet two 623, and the side wall of the piston cylinder 62 is provided with the air vent hole 624.

[0036] With such a scheme, when the contact sheet one 621 and the contact sheet two 623 are in contact, the air blower 642 can be automatically started, and when the contact sheet one 621 and the contact sheet two 623 are separated, the air blower 642 can be automatically closed, so as to ensure that the plated workpiece is dried in time after cleaning.

[0037] In specific work, when the piston rod 61 and the piston cylinder 62 approach each other, a certain amount of air pressure is generated in the piston cylinder 62, and under the action of the air pressure, the contact sheet two 623 above the contact sheet one 621 in the piston cylinder 62 moves downward, so as to extrude the plastic spring 622, so as to contact the contact sheet two 623 with the contact sheet one 621 to start the air blower 642, and under the action of the air vent hole 624, the excess gas in the piston cylinder 62 can be discharged. When the piston rod 61 and the piston cylinder 62 move away from each other, the contact sheet one 621 and the contact sheet two 623 can be automatically separated under the spring force of the plastic spring 622, and the air blower 642 is closed after the contact sheet one 621 and the contact sheet two 623 are separated.

[0038] When the piston rod 61 and the piston cylinder 62 are located at the leftmost side, the piston rod 61 is away from the piston cylinder 62, so the contact sheet one 621 and the contact sheet two 623 are not adhered to each other, and the air blower 642 is not started. When the piston rod 61 is displaced to the right, the piston rod 61 and the piston cylinder 62 are close to each other, the contact sheet one 621 and the contact sheet two 623 are pressed and adhered to each other under the pressure in the piston cylinder 62, the contact sheet one 621 and the contact sheet two 623 are adhered to start the air blower 642, so that the air blower 642 drives the dust particles on the surface of the coated workpiece to be cleaned in advance, so as to ensure the working efficiency of the later cleaning. When the piston rod 61 and the piston cylinder 62 pass through the highest part of the guide groove 8 and are located at the right side, the piston rod 61 and the piston cylinder 62 are away from each other, the pressure in the piston cylinder 62 is small, and the contact sheet one 621 and the contact sheet two 623 are separated, so that the air blower 642 is closed, and the piston cylinder 62 drives the placing mechanism 7 to be displaced to the rightmost position of the guide groove 8, so that the placing mechanism 7 can be slowly placed into the ultrasonic cleaner 3 for cleaning work. When the coated workpiece in the placing mechanism 7 is cleaned, the moving seat 5 drives the piston rod 61 and the piston cylinder 62 to be displaced to the left, the piston rod 61 and the piston cylinder 62 are close to each other to generate pressure, the contact sheet two 623 and the contact sheet one 621 are pressed and adhered to each other under the influence of the pressure, so as to start the air blower 642, the gas generated by the air blower 642 blows the ultrasonic cleaner 3, the coated workpiece in the placing mechanism 7 is dried to prevent the water from remaining on the coated workpiece to cause the oxidation and discoloration of the film, when the piston rod 61 and the piston cylinder 62 pass through the highest part of the guide groove 8, the piston rod 61 and the piston cylinder 62 are away from each other, so that the contact sheet two 623 and the contact sheet one 621 are separated to close the air blower 642, so as to clean the coated workpiece by the same operation mode.

[0039] It is to be noted that the contact sheet one 621 and the contact sheet two 623 are insulators, and liquid cannot enter the piston cylinder 62 to connect the contact sheet one 621 and the contact sheet two 623.

[0040] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
