Said lifting feed unit is screw pair worm drive structures.
The invention has the beneficial effects as follows: adopt said structure; Velocity of rotation through digital frequency conversion controller programming Control drive motors; Drive to promote feed unit and rise earlier carrier is placed solution container, and then slowly descend and carry out plated film, adopt the motionless and coated solution of carrier to move downward to leave carrier fashion and carry out plated film; Avoided carrier rocking in the process of lifting, thereby guaranteed that the whole even film layer that lifts the process carrier has solved stability and uniformity that carrier surface is filmed; The rotation platform of four stations is set, makes and carrier, plated film are installed and are dried substep and carry out continuously, improve plated film efficient; The plated film stroke of coating machine can be adjusted, and its scope is 0-2000mm, is fit to the product of processing plurality of specifications, and coating speed is per minute 0-200mm, and coating speed can guarantee the carrier surface film quality according to the adjustment of plated film product.
Description of drawings
Combine accompanying drawing that the present invention is done further elaboration at present:
Fig. 1 is that the master of numerical control pull-type coating machine of the present invention looks sketch map;
Fig. 2 is the schematic top plan view of numerical control pull-type coating machine of the present invention.
The specific embodiment
Like Fig. 1 or shown in Figure 2, the present invention includes frame 1 and the rotation platform 2 of being located at frame 1 crown center, said rotation platform 2 corresponding four stations 201,202,203,204 are provided with; Wherein first station 201 is the station of installing, dismounting needs the carrier 3 of plated film; Second station 202 is for drying station, and the 3rd station 203 is for lifting the plated film station, and the 4th station 204 is for drying station; Dry station drying unit such as air-heater can be set; Also be provided with the solution pulling apparatus 4 that matees with the 3rd station 203 on the said frame 1, said solution pulling apparatus 4 is provided with and promotes feed unit 41, promotes on the feed unit 41 and is connected with planker 42; Planker 42 is provided with the barrel frame 43 of fixed solution container 5, promotes feed unit 41 and also is connected with driving mechanism 6; The rising earlier of said lifting feed unit 41 places solution container 5 with carrier 3 during plated film, promotes feed unit 41 then and slowly descends, and after lifting feed unit 41 descended, the carrier 3 that is contained on the rotation platform 2 can not interfered with solution container 5.In order to reduce impact, promote in the feed unit 41 and can set up counter weight device.
Said rotation platform 2 comprises reversing frame 21, is located at the rotating shaft 22 at reversing frame 21 centers and the supporting base 23 of fixed rotating shaft 22; Reversing frame 21 is provided with the positioner 24 of the immobilization carrier 3 of four respectively corresponding four stations 201,202,203,204; Rotating shaft 22 1 ends are connected and fixed on the drive unit 7 on the frame 1; Positioner 24 adopts the hook that hangs carrier 3, and the structure of drive unit 7 is similar with driving mechanism 6.
Said driving mechanism 6 comprises the digital frequency conversion controller 63 of drive motors 61, the decelerator 62 that links to each other with drive motors 61 and control connection drive motors 61, and drive motors 61 is selected the 1.5KW asynchronous machine for use, and it can drive and promote the above load of 300kg.
Said coating machine is provided with controller 8, and rotation platform 2 is provided with the sensor 81 that detects its turned position, promotes feed unit 41 two ends and is provided with travel switch 82, and controller 8 links to each other with digital frequency conversion controller 63, sensor 81, travel switch 82 respectively.Sensor 81 can be photoelectric sensor or non-contact inductive switch.
The speed that said lifting feed unit 41 descends is by 63 controls of digital frequency conversion controller, and its decrease speed is per minute 0-200mm.
The stroke of said lifting feed unit 41 is 0-2000mm.
Said lifting feed unit 41 is screw pair worm drive structures.
The workflow of said pull-type coating machine is: install carrier 3 backs at first station and start coating machine; By stopping behind drive unit 7 driven rotary platforms 2 transpositions 90 degree, carrier 3 is sent to second station, opens two station air-heaters; Drive unit 7 stops behind driven rotary platform 2 transpositions 90 degree more then; Carrier 3 is sent to the 3rd station, is driven by drive motors 61 and promotes feed unit 41 risings, and the coated solution in the solution container 5 is arrived peak without the frequency control fast lifting; Drive motors 61 reverses behind frequency converter timing then; Drive and promote the speed decline of feed unit 41, carrier 3 (like glass tube) is carried out plated film, drop to minimum point rear drive motor 61 and shut down with per minute 0-200mm; And then by stopping behind drive unit 7 driven rotary platforms 2 transpositions 90 degree, carrier 3 is sent to the 4th station, opens the 4th station air-heater, and at last by stopping behind drive unit 7 driven rotary platforms 2 transpositions 90 degree, carrier 3 is sent back to the dismounting of first station; So can circulate and constantly carry out plated film.Start and stop between each station control is controlled by controller 8 and sensor 81, travel switch 82 automatically, also can be by manual control.
