Description

Technical Field

[0001] This invention relates to the field of circuit board processing technology, specifically to a PCB integrated circuit board processing equipment. Background Technology

[0002] In the wet etching process of PCBs (printed circuit boards), horizontal spray etching equipment is widely used due to its high operating capacity and production efficiency. This type of equipment typically uses conveyor rollers to horizontally transport the circuit board to the area below the spray device, where etching solution is sprayed from above to form the desired conductive lines.

[0003] However, in actual processing, it was found that when the circuit board is sprayed horizontally on one side, the etching solution easily accumulates in the central area of ​​the board due to surface tension, forming a thick liquid film and creating a "pool effect." This results in a significant difference in the concentration of the etching solution and the reaction rate in this area compared to the surrounding areas, leading to deviations in the lateral etching or insufficient etching in certain areas, severely affecting etching uniformity and product yield. To improve etching uniformity, the circuit board can be tilted appropriately during the spraying process to accelerate the drainage and renewal of the etching solution. In existing equipment, the circuit board is always supported by the conveyor rollers during the spraying process, lacking a structure to lift the circuit board away from the conveyor rollers and tilt it during spraying, making tilt adjustment impossible. Summary of the Invention

[0004] The purpose of this invention is to provide a PCB integrated circuit board processing equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PCB integrated circuit board processing equipment, comprising a housing, conveying rollers disposed within the housing, and a spraying device disposed on the top of the housing, and further comprising:

[0006] A lifting device is disposed inside the box. The lifting device includes two sets of lifting plates and a driving structure for driving the two sets of lifting plates to move relative to each other to clamp the circuit board. Each lifting plate is located in the gap between two adjacent conveying rollers.

[0007] A lifting device is located at the bottom of the box and is used to drive the lifting device to lift and lower so that the circuit board is detached from the conveying roller;

[0008] A swaying device is disposed between the lifting device and the lifting device for driving the clamped circuit board to tilt.

[0009] A tray is positioned between the swaying device and the lifting device.

[0010] Preferably, the driving structure includes a first housing, a connecting plate fixed to the lower end of each set of lifting plates, and a sliding plate fixed to the connecting plate;

[0011] The sliding plate slides into the first box and is fixedly connected to the mounting plate. There are two sets of mounting plates, which are symmetrically arranged inside the first box. Each of the two mounting plates has a rack fixed at one end that is close to the other, and a gear meshes between the two racks.

[0012] Preferably, a rotating column is fixed in the middle of the gear, the rotating column is rotatably disposed inside the first housing, a first worm gear is fixed on the rotating column, a first worm is meshed on the first worm gear, and a first motor is connected to the first worm.

[0013] Preferably, the shaking device includes a second housing fixed to the tray, a second worm gear disposed inside the second housing, and a rotating connecting rod fixed to one end of the second worm gear;

[0014] The other end of the rotating connecting rod extends out of the second housing and is rotatably connected to the second housing. A fixed connecting seat is fixed on the rotating connecting rod, and the first housing is fixedly connected to the end of the fixed connecting seat. A second worm is meshed on the second worm wheel, and a second motor is connected to the second worm.

[0015] Preferably, the lifting device includes a third box fixed to the bottom of the box body, an electric push rod installed in the third box body, and a support plate fixed to the output end of the electric push rod. A guide rod is fixed on the support plate, and the guide rod slides out of the third box body and is fixedly connected to the support plate.

[0016] Preferably, the spraying device includes multiple diversion pipes installed on the top of the housing, with inlet pipes connected to the multiple diversion pipes and multiple outlet pipes connected to each diversion pipe.

[0017] Preferably, each of the supporting plates is fixed with an anti-slip pad, which is used to contact the edge of the circuit board.

[0018] Preferably, the lifting plate is disposed in the gap between every two adjacent conveying rollers, and the width of the lifting plate is smaller than the width of the gap.

[0019] Preferably, the lifting device drives the pallet to move up and down, and the pallet synchronously drives the swaying device and the lifting device to rise and fall, so that the circuit board is disengaged from or in contact with the conveying roller.

[0020] Preferably, when the shaking device drives the lifting device to swing, the tilt angle of the circuit board surface relative to the horizontal direction is 0° to 10°.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By using a shaking device to drive a lifting device, the clamped circuit board is swung around a fulcrum, changing it from a horizontal to an inclined state. The inclined angle accelerates the flow of the etching solution accumulated in the center area of ​​the board to a lower position, effectively eliminating the local concentration difference of the etching solution caused by the "pool effect", thereby significantly improving the uniformity of single-sided etching and reducing side etching defects.

[0023] 2. The first motor drives the first worm gear and the first worm wheel to make the two sets of lifting plates move synchronously towards each other. The anti-slip pads on the lifting plates clamp and fix the circuit board from both sides, which not only ensures that the circuit board remains stable during tilting and shaking, avoiding displacement or falling off, but also prevents the clamping structure from blocking the etched area of ​​the board surface.

[0024] 3. The lifting device drives the lifting device to lift the circuit board upwards so that it is completely separated from the conveyor roller, providing sufficient space for subsequent tilting operations and avoiding interference from the conveyor roller when adjusting the posture of the circuit board.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Please see Figures 1 to 10 This invention provides a technical solution: a PCB integrated circuit board processing equipment, including a housing 3, a conveying device 1, conveying rollers 2, a spraying device 4, a lifting device 6, a shaking device 7, a lifting device 9, and a pallet 10. The housing 3 has an internal cavity for etching. Openings for circuit boards 5 to enter and exit are provided on the left and right sides of the housing 3. The conveying device 1 is correspondingly positioned on the infeed side of the housing 3 to feed the circuit boards 5 to be etched into the housing 3. Multiple conveying rollers 2 are evenly spaced along the length of the housing 3, and are at the same horizontal height to receive and horizontally convey the circuit boards 5. Each conveying roller 2 is connected to the drive end of the conveying device 1 via chain drive or belt drive to achieve synchronous rotation.

[0039] The circuit board 5 is horizontally conveyed to the area directly below the spray device 4 by the conveyor roller 2 driven by the conveyor device 1. The non-etched surface of the circuit board 5 is pre-coated with an anti-etching protective layer before etching. A photoelectric sensor is also installed on the inner wall of the housing 3 near the spray device 4. The transmitter and receiver of this photoelectric sensor are positioned opposite each other on the upper and lower or left and right sides of the conveying path of the circuit board 5, and its signal output is electrically connected to the control terminal of the conveyor device 1. When the circuit board 5 moves to the area below the spray device 4, the photoelectric sensor is triggered and sends a stop signal to the conveyor device 1, causing the circuit board 5 to stop accurately at the processing station.

[0040] like Figure 2 and Figure 3 As shown, the spraying device 4 is located at the top inner wall of the housing 3 and is used to spray etching solution onto the upper surface of the circuit board 5. The spraying device 4 includes an inlet pipe 41, multiple branch pipes 42, and multiple outlet pipes 43 connected to each branch pipe 42. One end of the inlet pipe 41 extends outside the housing 3 and is connected to an external liquid supply system, while the other end is connected in parallel to the multiple branch pipes 42 inside the housing 3. The multiple branch pipes 42 are arranged parallel to each other and spaced apart along the width direction of the housing 3, and are fixedly installed at the top inner wall of the housing 3 by pipe clamps. Multiple mounting holes are evenly opened on the lower side wall of each branch pipe 42 along its length direction, and multiple outlet pipes 43 are installed at each mounting hole, with the nozzles of the outlet pipes 43 pointing vertically downward toward the upper surface of the circuit board 5. The liquid outlet pipe 43 can be a fan-shaped nozzle or a solid cone nozzle. Its spray angle can be selected according to the etching process requirements to ensure that the etching solution can evenly cover the upper surface of the entire circuit board 5. A liquid outlet is set at the bottom of the box 3 to discharge the etching solution that accumulates in the box 3 after spraying in a timely manner, so as to avoid the liquid accumulation affecting the stability of the processing environment.

[0041] like Figure 2 , Figure 6 and Figure 7As shown, the lifting device 6 is located inside the housing 3, below the horizontal plane of the conveyor rollers 2, and is used to clamp and lift the circuit board 5 from both sides. The lifting device 6 includes two sets of lifting plates 61 and a drive structure for driving the two sets of lifting plates 61 to move relative to each other. Each set of lifting plates 61 is a long strip structure made of stainless steel or engineering plastic, with sufficient structural strength to support the weight of the circuit board 5. The projection of each lifting plate 61 on the horizontal plane is located in the gap between two adjacent conveyor rollers 2, and the width of the lifting plate 61 is smaller than the width of the gap, to ensure that the lifting plate 61 does not mechanically interfere with the conveyor rollers 2 during lifting, lowering, and swinging. Each support plate 61 has an anti-slip pad 62 attached to its upper surface by adhesive. The anti-slip pad 62 is made of acid and alkali resistant rubber or silicone material, and its upper surface is frosted or has anti-slip texture. It is used to fit tightly against the lower edge of the circuit board 5 when clamping the circuit board 5. On the one hand, it increases the friction to prevent the circuit board 5 from slipping off in the tilted state. On the other hand, it uses the elasticity of the material to avoid the clamping force from causing pressure or scratches on the edge of the circuit board 5.

[0042] like Figure 6 and Figure 7 As shown, in the drive structure, the first housing 66 is a rectangular hollow shell structure, horizontally positioned below the conveyor roller 2. Each supporting plate 61 has a vertically extending connecting plate 63 bolted to its lower end. One end of the connecting plate 63 is fixedly connected to a sliding plate 64. The sliding plate 64 is horizontal, with one end sliding into the interior of the first housing 66 through a guide groove in the side wall, and a mounting plate 65 fixedly connected to the extended end. There are two sets of mounting plates 65, symmetrically arranged on the left and right sides inside the first housing 66. A rack 67 is fixed to the end of each mounting plate 65 that is close to each other. The two racks 67 are horizontally opposite each other with their tooth surfaces facing each other. A gear 68 meshes between the two racks 67. The gear 68 is a spur gear, with a rotating column 69 fixedly passing through its center. The rotating column 69 is rotatably positioned inside the first housing 66 via a bearing.

[0043] A first worm gear 610 is fixed on the rotating column 69. The first worm gear 610 is connected and fixed to the rotating column 69 by a key. A first worm 611 meshes above the first worm gear 610. The two ends of the first worm 611 are rotatably mounted on the inner wall of the first housing 66 through bearing seats. One end of the first worm 611 extends out of the first housing 66 and is fixedly connected to the output shaft of the first motor 612 through a coupling. The first motor 612 is a forward and reverse reversible motor, which is fixedly installed inside the first housing 66. The power line of the first motor 612 is electrically connected to the main control system of the equipment to receive forward and reverse control commands. In addition, sliding rods 613 are fixed on the two mounting plates 65 respectively. The sliding rods 613 extend horizontally and slide into the guide holes opened inside the two racks 67 respectively to prevent the racks 67 from deflecting during movement and to ensure that the two racks 67 always maintain precise meshing with the gears 68.

[0044] like Figure 7 and Figure 8 As shown, the swaying device 7 is located between the lifting device 6 and the lifting device 9, and is used to drive the clamped circuit board 5 to tilt and swing around a horizontal axis. The second box 71 is fixedly installed on the upper surface of the support plate 10. The second box 71 is also a rectangular hollow shell structure. The second worm gear 72 is rotatably installed inside the second box 71, and a rotating connecting rod 73 is fixedly inserted through the center of the second worm gear 72. One end of the rotating connecting rod 73 extends out of the side wall of the second box 71 and is rotatably connected to the side wall through a bearing. A fixed connecting seat 74 is fixedly connected to the rotating connecting rod 73, and its upper part is fixedly connected to the bottom of the first box 66 by bolts. The extended end of the rotating connecting rod 73 is rotatably installed on a support plate, which is fixed to the upper surface of the support plate 10 to achieve stable support for the rotating connecting rod 73.

[0045] A second worm 75 meshes with the second worm gear 72. Both ends of the second worm 75 are rotatably mounted inside the second housing 71 via bearing seats. One end of the second worm 75 is fixedly connected to the output shaft of the second motor 76 via a coupling. The second motor 76 is also a reversible motor, fixedly mounted on the outer wall of the second housing 71, and its power line is electrically connected to the main control system. The second motor 76 can be a geared motor. When tilted, the circuit board 5 can swing left and right about the center line of the rotating connecting rod 73. Simultaneously, the meshing between the second worm gear 72 and the second worm 75 has a self-locking characteristic; that is, when the second motor 76 stops rotating, the circuit board 5 can stably maintain any tilt angle without automatically falling back under gravity. In specific implementation, the circuit board 5 is driven to tilt at a small angle of 0° to 10°, preferably 5° to 8°, by the shaking device 7. This utilizes gravity to accelerate the discharge of liquid from the plate surface while preventing the edge of the plate from exceeding the coverage area of ​​the spray device 4 due to excessive tilt angle.

[0046] like Figure 2 , Figure 9 and Figure 10 As shown, the lifting device 9 is located at the bottom inner wall of the housing 3 and is used to drive the lifting device 6 to lift as a whole. The lifting device 9 includes a third housing 91, an electric push rod 92, a support plate 93, and a guide rod 94. The third housing 91 is a rectangular hollow shell structure, which is fixedly installed on the inner bottom surface of the housing 3 by bolts. Its interior is the mounting cavity for the electric push rod 92. The electric push rod 92 is vertically installed inside the third housing 91. The lower end of its cylinder is fixedly connected to the inner bottom of the third housing 91 by bolts, and its telescopic rod is fixedly connected to the support plate 93.

[0047] The supporting plate 93 is a horizontal plate structure located inside the upper part of the third housing 91. A vertically extending guide rod 94 is fixed to the upper surface of the supporting plate 93. The upper end of the guide rod 94 slides through a guide hole opened at the top of the third housing 91 and is fixedly connected to the lower surface of the support plate 10. Four guide rods 94 are symmetrically distributed to provide balanced lifting guidance, ensuring that the support plate 10 remains horizontal and does not tilt during lifting. A linear bearing or copper sleeve can be embedded in the guide hole at the top of the third housing 91 to reduce the frictional resistance when the guide rods 94 slide back and forth. The support plate 10 is a horizontally positioned rectangular plate structure. Its lower surface is fixedly connected to the upper end of the guide rod 94, and its upper surface is fixedly connected to the bottom of the second housing 71 of the shaking device 7. The power cord of the electric push rod 92 is electrically connected to the main control system, which controls its extension and retraction.

[0048] In practical applications, firstly, the circuit board 5 to be etched is placed stably on the upper surface of the conveyor roller 2. The conveyor device 1 is then started, driving multiple conveyor rollers 2 to rotate synchronously, thereby feeding the circuit board 5 horizontally into the housing 3. When the circuit board 5 moves directly below the spray device 4, the photoelectric sensor installed inside the housing 3 detects that the circuit board 5 has reached its position and immediately sends a stop signal to the control terminal of the conveyor device 1. The conveyor device 1 stops rotating, and the circuit board 5 stops accurately at the processing station. At this time, the circuit board 5 is still placed horizontally on the upper surface of the conveyor roller 2, with its lower surface in contact with the conveyor roller 2.

[0049] Subsequently, the clamping action is initiated. The main control system sends a forward rotation command to the first motor 612, which drives the first worm gear 611 to rotate. The first worm gear 611 drives the first worm wheel 610, which meshes with it, to rotate. The first worm wheel 610 drives the gear 68 to rotate synchronously via the rotating column 69. When the gear 68 rotates, it simultaneously drives the two racks 67 on its upper and lower sides to move towards each other in the horizontal direction. The two racks 67 respectively drive their fixed mounting plates 65 to move. The mounting plates 65 drive the sliding plates 64 to slide into the first housing 66. The sliding plates 64 drive the two sets of lifting plates 61 to move towards each other synchronously via the connecting plate 63. During this process, the two sliding rods 613 slide in the guide holes of the two racks 67 respectively, ensuring that the racks 67 move smoothly and maintain correct meshing with the gears 68.

[0050] As the two sets of lifting plates 61 approach each other, the anti-slip pads 62 on the upper surface of the lifting plates 61 gradually approach the lower surface of the two side edges of the circuit board 5 until the anti-slip pads 62 are tightly attached to the edges of the circuit board 5. At this time, the first motor 612 stops rotating. Due to the self-locking characteristic of the worm gear pair, the two sets of lifting plates 61 maintain their current clamping position, and the circuit board 5 is stably clamped and fixed between the two sets of lifting plates 61.

[0051] Then, the lifting action is initiated. The main control system controls the extension of the electric push rod 92. The telescopic rod of the electric push rod 92 pushes the support plate 93 upward. The support plate 93 drives the guide rod 94 to slide upward simultaneously. The guide rod 94 pushes the pallet 10 to rise smoothly as a whole. When the pallet 10 rises, it simultaneously drives the swaying device 7 fixed on it, the lifting device 6 fixed on the swaying device 7, and the clamped circuit board 5 to move upward together. When the electric push rod 92 extends to the preset stroke and stops, the circuit board 5 has completely detached from the upper surface of the conveyor roller 2. A certain gap is formed between the lower surface of the circuit board 5 and the conveyor roller 2, providing sufficient space for subsequent tilting and swinging, and avoiding collision and interference between the circuit board 5 and the conveyor roller 2 when tilting.

[0052] Next, the tilting and swaying action is initiated. The main control system sends a rotation command to the second motor 76, which drives the second worm gear 75 to rotate. The second worm gear 75 drives the second worm wheel 72 to rotate, and the second worm wheel 72 drives the rotating connecting rod 73 to rotate around its own axis by a certain angle. The rotating connecting rod 73 drives the first housing 66 to swing synchronously around the axis of the rotating connecting rod 73 through the fixed connecting seat 74. The first housing 66, through the lifting device 6, drives the clamped circuit board 5 to tilt from a horizontal state to one side. The tilt angle can be controlled between 0° and 10° according to process requirements. The etching solution accumulated in the central area of ​​the board surface flows rapidly to the lower position and is discharged under the action of gravity, effectively eliminating the "pool effect". In order to ensure that the liquid accumulated on both sides of the circuit board 5 can be effectively discharged, the main control system can control the second motor 76 to alternately rotate forward and reverse, so that the left and right sides of the circuit board 5 tilt alternately, thereby realizing the continuous renewal of the liquid film on the board surface.

[0053] While the circuit board 5 is tilted and shaken, the etching solution is delivered through the inlet pipe 41 to multiple distribution pipes 42, and then evenly sprayed onto the upper surface of the circuit board 5 through multiple outlet pipes 43 on each distribution pipe 42. Because the circuit board 5 is in a tilted and shaking state, the etching solution sprayed onto the board surface will not stay in the central area for a long time, but will continuously flow and renew itself, ensuring the uniformity and consistency of the etching reaction across the entire board surface, and finally completing the etching process of the circuit board 5.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
