Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of exposure machine, concretely relates to an exposure machine with automatic dust removal function. BACKGROUND

[0002] The exposure machine is a kind of equipment for transferring specific pattern or image to photosensitive material, and is widely used in printing plate making, semiconductor manufacturing, PCB circuit board manufacturing and other fields.

[0003] Photosensitive material, such as halogenated silver photosensitive emulsion or photopolymerization photosensitive resin, is coated on the plate material. The exposure machine irradiates the plate material with light emitted by the light source, so that the photosensitive material undergoes photochemical reaction. For positive photosensitive material, the exposed part will dissolve in the developing solution, and the unexposed part will remain, forming a raised or recessed image opposite to the original image, such as making PS plate for offset printing.

[0004] When the exposure machine exposes the plate material, dust is easily adhered to the surface during the conveying process. Generally, dust removal operation is performed before exposure. The common dust removal method is to use wiping dust removal method, but this method cannot completely remove the dust on the surface, which will affect the product during exposure. UTILITY MODEL CONTENT

[0005] To solve the above technical problems, the utility model provides an exposure machine with automatic dust removal function.

[0006] The technical scheme of the utility model is realized as follows: an exposure machine with automatic dust removal function, comprising:

[0007] An exposure machine rack, a dust removal device and an exposure system are sequentially arranged on the exposure machine rack, and a reserved interval is arranged between the dust removal device and the exposure system for an operator to operate:

[0008] When the exposure plate material first passes through the dust removal device, the dust on the exposure plate material can be removed by the dust removal device, so that it enters the operation space and is paused. After the operator takes out the exposure plate material, exposure treatment is carried out at the exposure system.

[0009] A conveyor belt one and a conveyor belt two are arranged at the bottom of the dust removal device and the exposure system respectively, and the conveyor belt one and the conveyor belt two are respectively used for conveying materials in different processes.

[0010] The surface of conveyor belt one is provided with a fixed area. The purpose of the fixed area is to provide an installation space for the placement trough and ensure the stability of the placement trough installation. Specifically, hinge points can be set, and the fixed area is also provided with a magnetic area to magnetically connect the placement trough. In this way, when the placement trough is in the upper position, the placement trough can maintain a stable state. The bottom support plate ensures that the conveyor belt one is in a horizontal state when it is in the upper position. At this time, the placement trough is supported by the bottom support plate. Under the support of the bottom support plate, the exposure material can be stably conveyed, and the stability of dust removal can be improved during the dust removal process.

[0011] The dust removal equipment includes a charge generator disposed in the middle of the inner cavity and opposing to both sides, an ultrasonic generator disposed above the charge generator, and a dust collection mechanism disposed on both sides of the inner wall of the dust removal equipment.

[0012] The charge generator is connected to the negative terminal of a high-voltage DC power supply, and the dust collecting electrode is connected to the positive terminal. When the voltage rises to a certain level, gas molecules near the discharge electrode are ionized, generating a large number of electrons and positive ions. When the dust-laden gas passes through the high-voltage electrostatic field, it is electrically separated. The dust particles combine with the negative ions and become negatively charged, then tend to discharge and deposit on the anode surface. To ensure that the dust on the exposure plate can fully enter the air, the ultrasonic generator is set up so that the dust can be dispersed in the air by the vibration of the ultrasonic frequency. In this way, under the action of electrostatics, the dust can be completely adsorbed onto the dust collecting electrode.

[0013] Furthermore, both conveyor belt one and conveyor belt two include a drive shaft and an auxiliary conveying roller. Both conveyor belt one and conveyor belt two are connected to the drive shaft and the auxiliary conveying roller at their corresponding positions. Both the drive shaft and the auxiliary conveying roller are mounted on the exposure machine frame.

[0014] Furthermore, the ultrasonic generator includes an ultrasonic generating device, which is provided with an ultrasonic end mounting head, and the ultrasonic end mounting head is provided with an amplitude rod.

[0015] The amplitude rod includes a mounting rod, one end of which is provided with a downward-facing L-shaped rod, and the bottom end of the L-shaped rod is fixedly connected to a crossbar.

[0016] As the placement tank moves, the exposure plate comes into contact with the crossbar. The vibration generated by the crossbar causes the exposure plate to vibrate synchronously, thereby removing dust through vibration. This internal resonance combines electrostatic dust removal and vibration dust removal, thoroughly removing dust from the exposure plate.

[0017] Further, the inner wall of the conveying belt one and the conveying belt two is provided with a bottom supporting plate, the surface of the conveying belt one is provided with two groups of multiple placing grooves arranged at intervals, multiple exposure plates are arranged in the placing grooves, and gaps exist between the multiple exposure plates.

[0018] The placing grooves arranged at intervals are used for placing the exposure plates and inclining the placed exposure plates, so that the space for discharging dust is increased, the air flow in the inner wall is increased through the drying fan, the dust removal effect is improved, and in addition, when the inclined exposure plates contact the ultrasonic generator, the exposure plates can be deformed, and the dust on the surface of the exposure plates can be shaken off when the exposure plates shake.

[0019] Further, the charge generator comprises two charge generators arranged opposite to each other, a drying fan is arranged between the two charge generators, and a corona electrode is arranged on the outer side of the charge generator.

[0020] The drying fan can improve the drying degree of air and improve the electrostatic dust removal effect.

[0021] Further, the dust collecting mechanism comprises a side mounting plate, an inlay groove is formed in the side mounting plate, a dust collecting electrode is detachably connected in the inlay groove, a suction felt plate is arranged on the dust collecting electrode, and multiple suction strips and a sticky area are arranged on one side of the suction felt plate.

[0022] The utility model has the following beneficial effects:

[0023] 1. When the exposure plate first passes through the dust removal equipment, the dust on the exposure plate can be removed by the dust removal equipment, so that the exposure plate enters the operation space and is temporarily stopped in the operation space.

[0024] 2, the charge generator is connected to the negative pole of the high voltage DC power supply, and the dust collecting electrode is connected to the positive pole of the power supply. When the voltage rises to a certain extent, the gas molecules near the discharge electrode are ionized to produce a large number of electrons and positive ions. When the dust-containing gas passes through the high-voltage electrostatic field, it is electrically separated. The dust particles combine with negative ions to carry negative electricity, and then tend to discharge on the surface of the anode and deposit. In order to ensure that the dust on the exposure plate can be fully discharged into the air, the ultrasonic generator is arranged, which can make the dust in the air under the vibration of the ultrasonic frequency, so that the dust can be completely adsorbed on the dust collecting electrode under the action of static electricity.

[0025] 3, when the exposure plate is in contact with the horizontal rod during the movement of the placing groove, the vibration of the horizontal rod can make the exposure plate vibrate synchronously, thereby vibrating and removing dust, so that the internal co-vibration can be realized, and the static and vibration dust removal can be realized together, so that the dust on the exposure plate can be completely removed.

[0026] 4, the placing groove arranged at intervals is used for placing the exposure plate, and the placed exposure plate is arranged at an inclined angle, which is beneficial to improve the space of dust discharge, especially through the dry air blower, the flow rate in the inside can be improved, so that the air flows on both sides of the inner wall, and the dust removal effect is improved. In addition, it should be noted that when the exposure plate is in contact with the ultrasonic generator, the exposure plate can form a deformation effect, and the exposure plate can shake the dust on the surface during the separation process.
