Description

Technical Field

[0001] This invention relates to the field of etching machine technology, specifically to a 360-degree rotating and swinging spray vertical etching machine that can be connected to the network. Background Technology

[0002] The 360-degree rotating and swinging spray vertical etching machine is an etching equipment used in the processing of printed circuit boards and other fields. The conveying methods of the etching equipment include fixed, vertical and horizontal. The fixed type is to immerse the product directly in the etching tank. The vertical type uses clamps to vertically hang the product into the etching section and uses spray etching from both sides. It can also be connected with other equipment to realize automated production line operation.

[0003] Currently, the mainstream method is horizontal conveying. Horizontal conveying uses conveyor rollers with gaps between them, and nozzles are installed at the top and bottom to etch by spraying. The horizontal conveying speed is consistent, the etching is relatively uniform, the efficiency is high, and both sides can be etched at the same time.

[0004] During horizontal etching, because the product is conveyed by the conveyor rollers in a horizontal position, the etching solution is easily retained in the gap between the rollers after being sprayed onto the board surface, which is called the pool effect. The retained etching solution has increased copper ion concentration and decreased reactivity, and forms a reaction difference with the newly sprayed etching solution, which directly leads to uneven etching rate on the product surface.

[0005] Therefore, a 360-degree rotating and swinging spray vertical etching machine that can be connected online is proposed to address the above problems. Summary of the Invention

[0017] Online-connectable 360-degree rotating and oscillating spray vertical etching machine

[0018] S1: The product to be etched is placed on the board loading device manually or by upstream online equipment. The internal electrical box of the board loading device is started, triggering the initialization of the equipment. At this time, the door opening mechanism on both sides of the vertical etcher is in the closed state to ensure the etching area is sealed. The board loading device conveys the product to the water washing device. The water washing pump is started, and the product surface is initially cleaned through the fan-shaped nozzle of the water washing pipe. The wastewater after cleaning is discharged through the built-in pipe.

[0019] S2: After washing, the product is conveyed to the entrance of the vertical etching machine by the roller conveyor. The drive device is started, and the rotation of the drive shaft drives the bracket to rotate upward around the support axis, so that the sealing cover is detached from the glass door, opening the entrance of the etching area. After the product enters, the drive device rotates in the opposite direction, and the sealing cover re-attaches to the glass door, realizing the sealing of the etching area.

[0020] S3: Simultaneously, the transmission gear receives external power, driving the main transmission gear to rotate. The main transmission gear, through meshing with the first bevel gear and the second bevel gear, transmits power to the conveyor roller and the transmission roller support shaft. The conveyor roller drives the frame fixture and the workpiece to move and position precisely within the vertical etching machine. This causes the two drive spur gears and the large gear to rotate. The large gear meshes with the transition wheel, and the eccentric gear meshes with the transition wheel. Through the transmission of the eccentric gear, the carrier rotates 360 degrees around the central axis of the skeleton, driving the product to rotate synchronously. The cam structure of the spur gear drives the frame fixture through the transmission system, causing the carrier to swing slightly ±15mm in the up, down, left, and right directions while rotating.

[0021] S4: At this time, the rotary motor starts, and its main shaft drives the nozzle to swing back and forth by ±30 degrees around the rotating shaft of the pressure plate. The active transmission pipe is connected to the external etching solution supply system. The etching solution enters the nozzle through the pipe and is evenly sprayed onto the surface of the product with the rotating amplitude through the nozzle.

[0022] S5: After etching is completed, the frame fixture exits the etching area under the drive of the roller conveyor, and the door opening mechanism reopens the exit, allowing the product to be directly conveyed to the drying equipment to complete the entire processing process.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, the device uses the 360-degree rotation and ±15mm swing movement of the frame fixture, combined with the ±30-degree swing spray of the nozzle assembly and the 45° tilted nozzle design, so that the etching solution can form a crisscrossing coverage trajectory on the product surface. This effectively solves the problem of uneven local etching caused by the pool effect or etching solution accumulation in traditional etching processes, improves the etching uniformity of the circuit board, and improves the etching line accuracy.

[0025] 2. In this invention, an automatic door opening mechanism is used to automatically open or close the inlet and outlet etching areas, thereby closing off all parts of the etching device except for the inlet and outlet interfaces. This improves the encapsulation of the entire etching device, avoids interference from external factors in the etching process, and reduces environmental pollution from the chemicals.

[0026] 3. In this invention, the nozzle assembly adopts an eccentric nozzle structure. The eccentric nozzle system is driven by a swing motor, which enables the nozzle to reciprocate at ±30 degrees. This allows for uniform crisscrossing swing spraying on the product surface, effectively improving the uniformity of etching and preventing uneven etching of the board.

[0027] 4. In this invention, the roller conveying device and roller conveying system enable the frame fixture to move in one direction or reciprocatingly. At the same time, the spur gear and cam structure enable the frame fixture to rotate 360 ​​degrees, which in turn drives the product to rotate 360 ​​degrees, effectively ensuring more comprehensive spraying.

[0043] Please see Figures 1-9 The present invention provides a technical solution:

[0044] A 360-degree rotating and oscillating vertical etching machine capable of being connected to a network includes an infeed device 1 with an internal electrical box, a washing device 2, and a vertical etcher 3. A roller conveyor 4 is fixedly installed on the bottom inner side of the vertical etcher 3, and a frame fixture 5 is fixedly connected to the inner side of the vertical etcher 3. The roller conveyor 4 includes a roller bolster 41, a drive pawl plate 42 fixedly connected to one side of the lower end of the roller bolster 41, a drive pawl 43 fixedly connected to the upper end of the drive pawl plate 42, a main drive gear 44 rotatably connected between the drive pawl plate 42 and the drive pawl 43, a first bevel gear 46 meshing with the outer side of the main drive gear 44, and a conveyor roller 45 fixedly connected to one end of the first bevel gear 46. On the other side of 44, a second bevel gear 47 is meshed with. One end of the second bevel gear 47 is fixedly connected to a transmission roller support shaft 48. One end of the transmission roller support shaft 48 is rotatably connected to a transmission roller support seat 49. One end of the transmission roller support shaft 48 passes through the transmission roller support seat 49 and is fixedly connected to one of the spur gears 410. One spur gear 410 meshes with the other spur gear 410. One end of the other spur gear 410 is rotatably connected to a large gear support seat 411. The other end of the other spur gear 410 is fixedly connected to a large gear support shaft 412. The other end of the large gear support shaft 412 is fixedly connected to a large gear 413. The outer side of the large gear 413 is meshed with the frame fixture 5.

[0045] The device utilizes the 360-degree rotation and ±15mm swing motion of the frame fixture 5, combined with the ±30-degree oscillating spray and 45° tilted nozzle design of the nozzle assembly 7, to create a crisscrossing coverage pattern on the product surface with the etching solution. This completely solves the problem of uneven etching caused by the "pool effect" or etching solution accumulation in traditional etching processes.

[0046] It should be noted that: a water washing device 2 is fixedly connected to one side of the plate feeding device 1, and a vertical etching machine 3 is fixedly connected to the other side of the water washing device 2. A rotary motor 6 is fixedly connected to the upper end of the vertical etching machine 3. One end of the main shaft of the rotary motor 6 passes through the upper end of the vertical etching machine 3 and is fixedly connected to a nozzle assembly 7. Door opening mechanisms 8 are fixedly connected to both sides of the vertical etching machine 3. The main drive gear 44 is a bevel gear, the conveyor roller 45 is a cylindrical rubber wheel, and the other end of the conveyor roller 45 is rotatably connected to one side of the roller rest 41. Two spur gears 410 are vertically distributed. The drive roller support seat 49 is fixedly welded to the inside of the vertical etching machine 3. The large gear... 413 is meshed with the outer side of the transition wheel 55. The center points of the two eccentric gears 56 and the transition wheel 55 are on the same horizontal line. The frame fixture 5 includes a skeleton 51. A carrier 52 is slidably connected to the inner side of the skeleton 51. A pressure roller side plate 53 is rotatably connected to one side of the carrier 52. A pressure roller 54 is rotatably connected to the outer side of the pressure roller side plate 53. The transition wheel 55 and the eccentric gear 56 are rotatably connected to the outer side of the lower end of the carrier 52. The eccentric gear 56 is meshed with the outer side of the transition wheel 55. A cover plate 57 is fixedly connected to one side of the eccentric gear 56. The outer side of the pressure roller 54, the eccentric gear 56, and the cover plate 57 are all in close contact with the outer side of the large rotating wheel 58.

[0047] Specifically: The product is smoothly transported horizontally by the support of the roller 41. The large gear 413 meshes with the eccentric gear 56 of the frame fixture 5, transmitting rotational power to the frame fixture 5 to provide power for its 360-degree rotation. After the product to be etched is placed on the carrier 52, the pressure roller side plate 53 drives the pressure roller 54 to rotate inward. The pressure roller 54 is in close contact with the large rotating roller 58, and the hanging fixture 59 is used to clamp and fix the product vertically. The cover plate 57 is in close contact with the large rotating roller 58 to limit the axial displacement of the eccentric gear 56 and ensure the stability of rotation and swing motion.

[0048] It should be noted that: the nozzle assembly 7 includes a pressure plate 71, with a nozzle 72 rotatably connected to the inner side of the pressure plate 71. One end of the main shaft of the rotary motor 6 is fixedly connected to the upper end of the nozzle 72. A nozzle 73 is fixedly connected to one side of the nozzle 72. An active transmission pipe 74 is rotatably connected to the lower end of the nozzle 72. The pressure plate 71 is rectangular, and its outer side is fixed to the upper inner side of the vertical etcher 3. The nozzles 72 are evenly distributed along the length of the pressure plate 71, and the nozzles 73 are distributed at a downward 45° angle. The other end of the active transmission pipe 74 extends to the outside of the vertical etcher 3 and connects to the etching solution supply system. The door opening mechanism 8 includes a glass door 81. A limiting ring 84 and a support shaft 87 are fixedly connected to one side of the glass door 81. A drive device 82 is fixedly connected to one side of the glass door 81. A drive shaft 83 is fixedly connected to the inside of the drive device 82. One of the brackets 85 is fixedly connected to the lower end of the drive shaft 83 through the limiting ring 84. The bottom of the other bracket 84 is rotatably connected to the outside of the support shaft 87. A sealing cover 86 is fixedly connected to one end of the two brackets 84. One side of the sealing cover 86 is in close contact with one side of the glass door 81. The two brackets 85 are symmetrically arranged on one side of the glass door 81. The length of the bracket 85 is adapted to the width of the glass door 81. The outside of the sealing cover 86 is in contact with the gap between the glass door 81 and the vertical etching machine 3.

[0049] Specifically: The pressure plate 71 is set to fix the installation position of the spray pipe, ensuring that the spray range covers the product. The spray pipe 72 swings back and forth by ±30 degrees around the rotation axis of the pressure plate 71, so that the spray direction of the nozzle 73 changes in real time. The nozzles 73 are distributed at a 45° angle downwards, forming a crisscross spray trajectory as the spray pipe 72 swings, and the etching solution is evenly sprayed on the surface of the product with a pressure of 2.0-2.5 kg, achieving etching without dead angles. The lower end of the spray pipe 72 is connected to the active transmission pipe 74 through a rotating sealing structure to ensure that the etching solution does not leak when the spray pipe 72 swings, and to continuously provide power for spraying.

[0050] Furthermore: when the sensor detects that the product is about to enter or leave the vertical etcher 3, the drive unit 82 receives the signal and starts, the drive shaft drives the bracket to reset, and the sealing cover 86 re-attaches to the glass door 81. The etching area is sealed through close contact to prevent the etching solution from evaporating and polluting the environment. The limit ring 84 limits the maximum stroke of the drive shaft 83 to avoid mechanical damage caused by excessive opening and closing of the sealing cover 86.

[0051] Workflow: Power is supplied via external wires. The product to be etched is placed on the board loading device 1 manually or by upstream connected equipment. The internal electrical box of the board loading device is activated, triggering equipment initialization. At this time, the door opening mechanisms 8 on both sides of the vertical etcher 3 are closed to ensure the etching area is sealed. The board loading device 1 transfers the product to the water washing device 2. The water washing pump is activated, and the product surface is initially cleaned through the fan-shaped nozzle of the water washing pipe. The wastewater after cleaning is discharged through the built-in pipe.

[0052] After washing, the product is conveyed by the roller conveyor 4 to the entrance of the vertical etcher 3. The drive device 82 is started, and the rotation of the drive shaft 83 drives the bracket 85 to rotate upward around the support shaft 87, so that the sealing cover 86 is detached from the glass door 81, opening the entrance of the etching area. After the product enters, the drive device 82 rotates in the opposite direction, and the sealing cover 86 re-attaches to the glass door 81, realizing the sealing of the etching area.

[0053] Meanwhile, the transmission gear 43 receives external power and drives the main transmission gear 44 to rotate. The main transmission gear 44, through meshing with the first bevel gear 46 and the second bevel gear 47, transmits power to the conveyor roller 45 and the transmission roller support shaft 48. The conveyor roller 45 drives the frame fixture 5 and the workpiece to move and position precisely within the vertical etching machine 3. This causes the two drive spur gears 410 and the large gear 413 to rotate. The large gear 413 meshes with the transition wheel 55, and the eccentric gear 56 meshes with the transition wheel 55. Through the transmission of the eccentric gear 56, the carrier 52 rotates 360 degrees around the central axis of the skeleton 51, causing the product to rotate synchronously. The cam structure of the spur gear 410 drives the frame fixture through the transmission system, causing the frame fixture 52 to swing slightly ±15mm in the up, down, left, and right directions while rotating.

[0054] At this time, the rotary motor 6 starts, and its main shaft drives the nozzle 72 to swing back and forth at ±30 degrees around the rotating shaft of the pressure plate 71. The active transmission pipe 74 is connected to the external etching solution supply system. The etching solution enters the nozzle 72 through the pipe and is evenly sprayed onto the surface of the product with the swing amplitude through the nozzle 73. After etching is completed, the frame fixture 5 exits the etching area under the drive of the roller conveyor 4. The door opening mechanism 8 opens the outlet again, and the product can be directly conveyed to the drying equipment to complete the whole process.

9. The 360-degree rotating and oscillating spray vertical etching machine that can be connected to the network according to claim 5, characterized in that: The two brackets (85) are symmetrically arranged on one side of the glass door (81). The length of the brackets (85) is adapted to the width of the glass door (81). The outer side of the sealing cover (86) is attached to the gap between the glass door (81) and the vertical etcher (3).

10. The 360-degree rotating and oscillating spray vertical etching machine based on any one of claims 1-9, characterized in that: The steps are as follows: S1: The product to be etched is placed in the board loading device (1) by manual operation or upstream online equipment. The internal electrical box of the board loading device is started, triggering the initialization of the equipment. At this time, the door opening mechanism (8) on both sides of the vertical etcher (3) is in the closed state to ensure the sealing of the etching area. The board loading device (1) transfers the product to the water washing device (2). The water washing pump is started, and the product surface is initially cleaned through the fan-shaped nozzle of the water washing pipe. The wastewater after cleaning is discharged through the built-in pipe. S2: After washing, the product is conveyed by the roller conveyor (4) to the entrance of the vertical etcher (3). The drive device (82) is started, and the rotation of the drive shaft (83) drives the bracket (85) to rotate upward around the support shaft (87), so that the sealing cover (86) is removed from the glass door (81), opening the entrance of the etching area. After the product enters, the drive device (82) rotates in the opposite direction, and the sealing cover (86) re-attaches to the glass door (81), thus sealing the etching area. S3: At the same time, the transmission pawl (43) receives external power and drives the main transmission gear (44) to rotate. The main transmission gear (44) transmits power to the conveying roller (45) and the transmission roller support shaft (48) by meshing with the first bevel gear (46) and the second bevel gear (47). The conveying roller (45) drives the frame fixture (5) and the workpiece to move and position precisely in the vertical etching machine (3), thereby driving the two drive spur gears (410) and the large gear (413) to rotate. The large gear (413) meshes with the transition wheel (55), and the eccentric gear (56) meshes with the transition wheel (55). Through the transmission of the eccentric gear (56), the carrier (52) rotates 360 degrees around the central axis of the skeleton (51), driving the product to rotate synchronously. The cam structure of the spur gear (410) drives the frame fixture (5) through the transmission system, so that the carrier (52) swings slightly ±15mm in the up, down and left and right directions while rotating. S4: At this time, the rotary motor (6) starts, and its main shaft drives the nozzle (72) to swing back and forth at ±30 degrees around the rotating shaft of the pressure plate (71). The active transmission pipe (74) is connected to the external etching liquid supply system. The etching liquid enters the nozzle (72) through the pipe and is evenly sprayed on the surface of the product with the rotating amplitude through the nozzle (73). S5: After etching is completed, the frame fixture (5) exits the etching area under the drive of the roller conveyor (4), and the door opening mechanism (8) opens the outlet again. The product can be directly conveyed to the drying equipment to complete the whole process.
