Description

Technical Field

[0001] The utility model relates to an etching line, in particular to a two-trough type fully automatic etching line. Background Art

[0002] Etching is also called corrosion or photochemical etching. It refers to the removal of the protective film of the area to be etched after exposure, plate making and development. During etching, it contacts the chemical solution to achieve the effect of dissolution and corrosion, forming a concave-convex or hollow-out effect.

[0003] The etching process is usually carried out under certain temperature conditions. The etching liquid is evenly sprayed onto the surface of the copper foil through the nozzle, and a redox reaction occurs with the material that is not etched and protected by the resist, and the unnecessary parts are reacted away. Etching is widely used in electronics, metal processing, glass manufacturing and other fields. When etching conventional plate-like objects, multiple opposite spray heads are evenly arranged on the transmission path according to the transmission direction of the workpiece to spray etching liquid on both sides of the workpiece. Regardless of the orientation and shape of the workpiece during transmission, after etching is completed, there will usually be etching liquid residue somewhere on the workpiece. If it is not removed in time, it will cause serious corrosion on the workpiece side and the etched product will have deviations in accuracy. Utility Model Content

[0023] 100: Artifacts DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0025] Example 1: A two-tank fully automatic etching line, such as Figure 1-7 As shown, it includes a base plate 1, a support frame 2, a transmission member 3, a mechanical arm 4, a material-retrieving arm 5, a hanging basket 51, a double-station slot 6, a swing motor 7, a guide rail 70, a spray member 71, a liquid pump 72, a nozzle 73, and a connecting rod. Support frames 2 are arranged on the left and right sides of the top of the base plate 1, and a transmission member 3 is arranged between the support frames 2. The transmission member 3 is composed of a guide rail, a driving motor and a screw rod. A mechanical arm 4 is arranged on the transmission member 3. When the screw rod of the transmission member 3 rotates, the mechanical arm 4 moves left and right on the guide rail of the transmission member 3. The mechanical arm 4 is equipped with a synchronous belt assembly driven by a servo motor. The synchronous belt in the mechanical arm 4 is fixedly connected with a material-retrieving arm 5. The material-retrieving arm 5 moves up and down on the synchronous belt rotating by the mechanical arm 4, and the moving position is controllable.

[0026] The picking arm 5 is composed of a mounting seat, two rotating hanging claws, and two picking motors. The left and right sides of the lower part of the mounting seat of the picking arm 5 are both rotatable and symmetrically provided with rotating hanging claws. The two rotating hanging claws are driven by the picking motor to realize rotation. The two rotating hanging claws rotate in opposite directions when rotating. A hanging basket 51 is hung on the rotating hanging claw of the picking arm 5. The hanging basket 51 is customized according to the shape and size of the processed product. When in use, multiple products can be neatly placed at one time for processing, and the efficiency is high. When the two rotating hanging claws are opened in opposite directions, the hanging basket 51 will detach from the rotating hanging claws. A number of card slots are evenly spaced inside the hanging basket 51. The card slots are used to place workpieces 100. There will be a gap between the workpieces 100 in the hanging basket 51. The workpieces 100 are placed in the direction such as Figure 4 As shown;

[0027] A double-station slot 6 is fixedly provided in the middle of the area between the two support frames 2 on the bottom plate 1, and two processing station slots are arranged in the double-station slot 6: the right side is arranged as an etching slot, and the left side is arranged as a cleaning slot, both of which can put the hanging basket into the inside for processing. During processing, a certain amount of etching liquid is injected into the bottom of the etching slot, and the liquid level is relatively low. The liquid level of the cleaning liquid in the cleaning slot should be relatively high, so that the hanging basket 51 can be completely immersed; guide rails 70 are welded on the left and right sides of the front side of the etching slot, and a swing motor 7 is installed on the bottom plate 1 near the front side of the etching slot. The swing motor consists of a motor, a reducer connected to the motor output shaft, and a movable rod for circular motion. A spray part 71 is slidably provided between the guide rails 70. The spray part 71 consists of a connecting frame, two symmetrically arranged spray rocking plates and a plurality of nozzles 73 installed on the spray rocking plates. The movable rod of the swing motor 7 is connected to the spray part 71 through a connecting rod 74, and the two ends of the connecting rod 74 are respectively connected to the movable rod of the swing motor 7. The connecting frame of the movable rod and the spray member 71 is hinged, and a connecting channel connecting each nozzle 73 should be provided in the spray rocking plate. The spray rocking plate is arranged on the left and right sides of the etching tank. When the hanging basket 51 is placed in the etching tank, it should be in the area between the two spray rocking plates. The nozzles 73 on both sides are facing one side of the hanging basket. When the swing motor 7 is working, the movable rod rotating in the circle of the swing motor 7 is driven by the connecting rod to drive the connecting frame of the spray member 71 to move up and down in the guide rail 70. The entire spray member 71 moves back and forth up and down with the action of the swing motor. The spray rocking plate and the nozzle 73 of the spray member 71 move up and down in the etching tank. A liquid extraction pump 72 is installed at the bottom of the etching tank of the double-station tank 6. The output end of the liquid extraction pump 72 is connected to two hoses through a three-way piece. The two hoses are respectively connected and communicated with the connecting channels on the spray rocking plates of the left and right spray members 71. When the liquid extraction pump 72 is working, the etching liquid in the etching tank is sprinkled onto the workpiece 100 on the hanging basket through the nozzle 73.

[0028] During processing, the hanging basket 51 is moved to the area between the right support frames 2 by external tools, and should be under the right part of the transmission member 3. The products to be processed are placed in the hanging basket 51. At this time, the mechanical arm 4 moves to the position just above the hanging basket on the right part of the transmission member 3, and the two hanging claws on the material taking arm 5 are in an open state. The material taking arm 5 moves downward and lifts the hanging basket 52 through the hanging claws. Then the material taking arm 5 moves upward, and the mechanical arm 4 moves to the top of the etching tank. The material taking arm 5 moves downward to put the hanging basket 51 into the etching tank, and the swing motor 7 and the liquid pump 72 are started. The nozzle 73 on the shower head 71 etches the workpiece. Through the swing of the nozzle 73, the spray liquid intermittently etches the upper edge and the lower end of the workpiece 100, so as to achieve uniform etching of the entire workpiece 100. After a period of time, the hanging basket 52 is moved to the cleaning tank by the robot arm 4 and the material picking arm 5, and the workpiece 100 is cleaned after etching to prevent the residual etching liquid from continuously reacting with the workpiece 100, resulting in accuracy deviation of the etched product. After cleaning, the hanging basket 51 is moved to the left part of the transmission part 3 by the robot arm 4 and the material picking arm 5 to complete the processing.

[0029] Embodiment 2: Based on embodiment 1, Figure 1-3 As shown, in order to realize the automation of processing, it also includes a trolley station 8, a material transfer trolley 81 and a limit plate 9. The trolley station 8 is set on the left and right sides of the bottom plate 1. The trolley station 8 is equipped with a material transfer trolley 81 for loading the hanging basket 51. The material transfer trolley 81 is customized according to the shape and size of the hanging basket 51. When the hanging basket 51 is transported by the material transfer trolley 81, the hanging basket 51 does not bump or shake, and the product is in a stable state. The limit plate is symmetrically installed on the inner side of the lower part of the support frame 2 9. The purpose of the limit plate is that when the material transfer trolley 81 is pushed into the trolley station 8, the material transfer trolley 81 can be directly positioned and placed through the limit plate 9, and is in the precise position for loading and unloading. There is no need for subsequent manual adjustment of the material transfer trolley 81. The material picking arm 5 can quickly pick up and place materials. Through the customized hanging basket 51, the matching material transfer trolley 81 and the automatic material transfer robot arm 4, the loading, processing and unloading automation is realized, which reduces manual intervention, reduces labor costs and improves processing efficiency.

[0030] In a preferred embodiment: Figure 5 and Figure 7As shown, an air pumping pipe 10 is also included. Two air pumping pipes 10 are arranged at the lower part of the etching tank and the cleaning tank of the double-station tank 6. A number of air holes are opened on the tube wall of the air pumping pipe 10. One end of the air pumping pipe 10 passes through the tank wall of the double-station tank 6 to connect to an external gas source. The air pumping pipe 10 is immersed in the liquid of the etching tank and the cleaning tank of the double-station tank 6. The exhausted gas forms bubbles in the liquid to stir the liquid. During etching, the regeneration of the medicine requires a large amount of oxygen. When the air pumping volume is insufficient, the oxygen supplement is insufficient and the medicine cannot be regenerated in time. Therefore, a certain amount of air pumping should be controlled, and the circulation of the circulating pump can be guaranteed to be uniform. During cleaning, the activity of the cleaning agent can be increased to ensure that the cleaned parts can be completely soaked. Under the action of bubble stirring, the dirt is brought into the liquid, or the residual liquid can be washed away from the surface of the product, thereby improving the cleaning efficiency and reducing the cleaning time.

[0031] In a preferred embodiment, a material discharging rack 11 is also included. The lower part of the etching tank and the cleaning tank of the double-station tank 6 is provided with a material discharging rack 11 which can stably support the hanging basket in the tank. The purpose of setting the material discharging rack 11 is to place the hanging basket 51 to be processed in the double-station tank for processing, without the need for the material picking arm 5 to lift the material, thereby reducing the ineffective occupancy of the material picking and material moving mechanism, and ensuring the orderly cycle of material loading, material moving and unloading, reducing the downtime of the robot arm 4 and the material picking arm 5, optimizing the use steps, and improving the processing efficiency.

[0032] In a preferred embodiment: Figure 1 and Figure 2 As shown, it also includes a closed outer cover 12, a roller shutter 13 and a curtain plate 14. The closed outer cover 12 is arranged around the outer periphery of the support frame 2. Channel openings for the movable material transfer trolley 81 to enter and exit are opened on the left and right sides of the closed outer cover 12. Rollers 13 are arranged on the inner upper part of the left and right sides of the closed outer cover 12. Retractable curtain plates 14 are wound on the roller shutters 13. When the etching line is processed, the curtain plates 14 are completely unwound to shield the channel openings. The fully closed outer cover 12 is completely closed. During the etching process, the influence of external factors on the operation of the processing equipment in the line body is effectively reduced. At the same time, the workers are separated from the moving mechanical arm 4 to reduce the harm caused to people by the moving mechanical equipment.

[0033] In a preferred embodiment: Figure 1 As shown, a transparent plate 15 is also included. At least two transparent plates 15 are provided on the front and rear sides of the closed outer cover 12 for observing the internal processing conditions from the outside of the equipment, so that workers can observe the processing status and respond and adjust to sudden situations in the closed outer cover 12 in a timely manner.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
