Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coating equipment, in particular to a rosin solution coating equipment. BACKGROUND

[0002] As the core substrate of printed circuit board, the circuit copper plate can effectively remove the oxidation layer on the surface of the copper plate, reduce the welding temperature, and form a protective film on the surface of the copper plate to avoid secondary oxidation in the subsequent processing and storage process, thereby ensuring the performance stability of the circuit copper plate.

[0003] Currently, the rosin solution coating of the circuit copper plate has defects, wherein the parallel arrangement of the coating roller and the pressure roller is used to apply constant pressure to the coating roller by the pressure roller to ensure that the outer periphery of the coating roller is tightly attached to the surface of the circuit copper plate, and a rosin solution conveying pipeline is arranged above the gap between the two rollers, the pipeline nozzle is aligned with the middle position of the gap between the coating roller and the pressure roller, and the rosin solution naturally flowing out of the pipeline nozzle is directly dropped on the surface of the coating roller during work, and the solution is transferred and indirectly applied to the surface of the circuit copper plate by the uniform rotation of the coating roller. However, this coating method cannot achieve uniform distribution of the rosin solution on the surface of the coating roller. On the one hand, the solution can only accumulate in the local area of the middle section of the gap between the coating roller and the pressure roller due to the action of gravity, and the positions of the two ends of the coating roller away from the middle section of the gap can only rely on the slow natural diffusion of the solution on the roller surface, which is easy to form distribution differences such as liquid accumulation in the middle section and liquid deficiency at the two ends. In addition, when the equipment is not in use, the rosin solution remaining on the surface of the coating roller is easy to solidify and form clumps, and the staff needs to manually apply the cleaning agent evenly on the surface of the coating roller to remove the remaining rosin solution. This kind of manual cleaning method is low in efficiency, and the manual application of the cleaning agent is also difficult to ensure comprehensive coverage, which is easy to cause the rosin to remain on the roller surface and affect the quality of the next coating. Therefore, it is necessary to design a rosin solution coating equipment.

[0021] The technical solutions provided by the embodiments of the present application are described in detail below in combination with the drawings.

[0022] Referring to Figures 1-3 As shown in the drawings, the rosin solution coating equipment provided by the embodiments of the present application comprises a feeding assembly 1, the feeding assembly 1 comprises a device shell one 11, and a moving module 13 is arranged at the top end of the inner wall of the device shell one 11, the moving module 13 is used for realizing the key components of circuit board transfer, wherein the moving module 13 is composed of a driving element, a transmission assembly, a guide component, a support fixing component and a moving component, wherein a downward cylinder one 14 is arranged on the moving component of the moving module 13, the telescopic end of the cylinder one 14 is fixed with a mounting plate (not marked in the drawing), and a plurality of groups of pneumatic clamps 15 are fixed on the bottom surface of the mounting plate, the pneumatic clamps 15 can be flexibly opened and closed to realize stable clamping and releasing of the circuit copper plate. Meanwhile, a conveyor (not shown in the drawing) is arranged transversely through the device shell one 11, in actual operation, the conveyor continuously conveys the circuit copper plate to be processed into the feeding assembly 1, so that the moving module 13 cooperates with the pneumatic clamps 15 to grasp, and a conveying belt one 12 is arranged on the inner wall bottom surface of the device shell one 11, the conveying belt one 12 is used for conveying the circuit copper plate after being clamped and discharged by the pneumatic clamps 15 to the next processing procedure, so as to guarantee the continuity and automation of the circuit copper plate coating process.

[0023] Meanwhile, the acid pickling assembly 2, the water washing assembly 3 and the drying assembly 4 are arranged in sequence on one side of the feeding assembly 1, and the conveying belt 12 is arranged through the acid pickling assembly 2, the water washing assembly 3 and the drying assembly 4, so as to drive the circuit copper plate into different processes in sequence and realize automatic continuous processing. Figure 3 It can be seen that the drying assembly 4 comprises a device housing two 41 arranged on one side of the device housing one 11, which provides a closed and stable space for drying operation; and a plurality of groups of drying rollers 42 are arranged between the inner walls of the device housing two 41, which are orderly distributed and can act on the circuit copper plate in all directions. The surface of the drying roller 42 is communicated with a spray head, which can uniformly spray the internal hot flow onto the circuit copper plate, and one end of the drying roller 42 is used for being communicated with an external heat supply device to continuously obtain the hot flow. It should be noted that the drying roller 42 has flexible application scenarios. When it is applied to the drying assembly 4, it is used for supplying the hot flow to rapidly evaporate the moisture on the surface of the circuit board by means of the hot flow, so as to realize drying. When it is applied to the acid pickling assembly 2, it is used for storing the acid pickling solution, which removes impurities and oxide layers on the surface of the circuit board by contacting the circuit board. When it is applied to the water washing assembly 3, it is used for storing the water washing solution, which rinses the circuit board after acid pickling, removes the residual acid pickling solution, and prepares for subsequent drying and coating processes, so as to ensure smooth connection between processes and improve the processing quality and efficiency of the circuit board.

[0024] As shown in Figure 1 and Figure 4 , a coating assembly 5 is arranged on one side of the drying assembly 4, which is used for forming a uniform rosin solution coating layer on the surface of the circuit board. The coating assembly 5 comprises two groups of mounting frames 51 arranged on one side of the drying assembly 4, and a coating roller 53 is connected to the two ends of the two groups of mounting frames 51 through a bearing seat 54. Meanwhile, a pressure roller is arranged at the upper left side of the coating roller 53 between the two groups of mounting frames 51. In actual operation, the pressure roller is used for applying a certain pressure to the coating roller 53, so that the coating roller 53 can tightly contact the surface of the circuit copper plate, and ensure that the rosin solution is uniformly coated on the circuit board. Meanwhile, a driving device is fixed on the side surface of one group of mounting frames 51. When the driving device works, it can synchronously drive the coating roller 53 and the pressure roller to rotate. The coating roller 53 carries the rosin solution and contacts the circuit board during rotation to complete coating, and the pressure roller assists the coating roller 53 to maintain the contact pressure with the circuit board. Furthermore, a conveying belt two 52 is arranged between the two groups of mounting frames 51, which is used for bearing the circuit copper plate after the drying process and stably conveying it to the lower side of the coating roller 53, so that the coating roller 53 can perform coating operation on it.

[0025] As shown in Figures 4-8As shown, the application is characterized in that a coating assembly 6 is arranged between the two sets of mounting racks 51, and the coating assembly 6 can uniformly coat the rosin solution on the surface of the coating roller 53 during actual coating operation. The coating assembly 6 comprises a moving part fixed between the two sets of mounting racks 51, the moving part comprises a guide rod 61 fixed between the two sets of mounting racks 51 and above the coating roller 53, a lead screw 62 is arranged on one side of the guide rod 61, and the two ends of the lead screw 62 are arranged on the two sets of mounting racks 51 through bearings; and an arc-shaped coating piece 63 is movably sleeved on the guide rod 61, the coating piece 63 is a hollow structure, and the coating piece 63 has two sets of fixed sleeves 64; One set of fixed sleeves 64 is movably sleeved on the guide rod 61, and the other set of fixed sleeves 64 is threadedly connected with the lead screw 62. The guide rod 61 plays a guiding role in the movement of the coating piece 63, ensuring that the coating piece 63 moves stably along a straight line. When the lead screw 62 rotates, the coating piece 63 can be driven to move along the guide rod 61. A driving motor (not shown in the figure) is fixed on the side of one set of mounting racks 51. During actual production, the driving motor provides power for the rotation of the lead screw 62. The driving motor is connected with one end of the lead screw 62 through a shaft coupling. The shaft coupling can effectively transmit torque, ensuring the stability of power transmission.

[0026] An arc-shaped partition plate 65 is fixed at the center position of the coating piece 63. The partition plate 65 is used to divide the coating piece 63 into two sets of partition areas. Herein, the left partition area is defined as a first partition area, and the right partition area is defined as a second partition area. Figure 8 A coating part is arranged on the inner wall of the coating piece 63. The coating part comprises a shielding plate 66 fixed on the inner wall of the coating piece 63 and in the first partition area. The shielding plate 66 is in an arc-shaped structure and can better adapt to the arc-shaped surface of the coating roller 53. The shielding plate 66 has an outwardly extending mesh plate 67. The mesh plate 67 is in an arc-shaped structure. One end of the mesh plate 67 of the shielding plate 66 is fixedly connected with the partition plate 65 to form a first mounting space. An arc-shaped sponge block one 624 is arranged in the first mounting space. The sponge block one 624 can absorb and store rosin solution during actual use. The sponge block one 624 is arranged in close contact with the mesh plate 67. The rosin solution can uniformly permeate the sponge block one 624 through the mesh plate 67. A pressing plate one 628 is connected with the upper end position of the sponge block one 624 in the first mounting space through a spring three. The pressing plate one 628 is in an arc shape and is arranged in close contact with the sponge block one 624. The spring three can reset the sponge block one 624 by applying pressure to the sponge block one 624 through the pressing plate one 628. When the sponge block one 624 is extruded, the rosin solution can permeate the mesh plate 67 and fall on the surface of the coating roller 53. The rosin solution can be uniformly coated on the circuit copper plate through the contact and rotation of the coating roller 53 and the pressure roller.

[0027] AsFigures 8-9 As shown, the pressing part is arranged on the coating piece 63, which comprises four groups of supporting rods 613 fixed on the coating piece 63, guide rods 614 fixed between the two groups of supporting rods 613, the guide rods 614 play a guiding role, and a mounting box 615 is slidingly arranged between the two groups of guide rods 614, the mounting box 615 can stably slide along the guide rods 614, and a vertically arranged extrusion rod 617 is movably arranged on the mounting box 615, one end of the extrusion rod 617 is spherical, and the other end of the extrusion rod 617 penetrates the coating piece 63 and is in contact with the top surface of the first pressing plate 628, so as to apply pressure to the first pressing plate 628, and an open slot is formed on the coating piece 63 and matched with the spherical end of the extrusion rod 617, the open slot can limit the lateral movement of the spherical end of the extrusion rod 617, and in actual coating operation, the pressing part can extrude the first pressing plate 628, so that the sponge block 624 is in contact with the mesh plate 67, and the rosin solution falls on the surface of the coating roller 53 through the mesh holes of the mesh plate 67. A limiting piece is sleeved on the extrusion rod 617, the limiting piece is located in the mounting box 615 and is used for limiting the movement range of the extrusion rod 617, a spring 618 is sleeved on the extrusion rod 617, one end of the spring 618 is connected with the limiting piece, and the other end of the spring 618 is connected with the bottom end of the inner wall of the mounting box 615, the spring 618 can reset the extrusion rod 617 when the extrusion rod 617 is not subjected to external force, and one end of the extrusion rod 617 penetrating the mounting box 615 is fixed with a pressing piece 626, the bottom surface of the pressing piece 626 is fixed with four groups of guide shafts 627, the guide shafts 627 play an auxiliary guiding role, so that the pressing piece 626 moves more stably, and one end of the guide shaft 627 movably penetrates the mounting box 615; Meanwhile, a driving part for driving the extrusion rod 617 to move up and down to press the sponge block 624 through the first pressing plate 628 is connected between the two groups of fixed sleeves 64, the driving part comprises two groups of supporting pieces 68 fixed on the two groups of fixed sleeves 64, a rotating shaft 69 movably connected between the two groups of supporting pieces 68, the rotating shaft 69 can flexibly rotate, a cam 611 sleeved on the central position of the rotating shaft 69, the side edge of the cam 611 is in contact with the top surface of the pressing piece 626, the cam 611 can drive the pressing piece 626 to move up and down when the cam 611 rotates, a gear 610 sleeved on the rotating shaft 69 at positions on both sides of the cam 611, and a rack 612 fixed between the two groups of mounting frames 51 and engaged with the gear 610, when the coating piece 63 moves along the guide rod 61, the gear 610 rotates by engaging with the rack 612, drives the rotating shaft 69 and the cam 611 to rotate, and then drives the pressing piece 626.

[0028] It needs to be explained that, in the default state, when the pressing part is at both ends of the rack 612, the spring 618 is in a natural state of extension and will not be compressed, that is, the lowest side of the cam 611 is in contact with the surface of the pressing piece 626. The design of this structure makes the spherical end of the extrusion rod 617 not extend into the coating piece 63 and be in contact with the surface of the pressing plate 628. This state can stop the extrusion of the sponge block 624 when the coating piece 63 moves to the end of the stroke, avoiding the waste caused by the continuous leakage of the rosin solution. As Figures 10-11 shown, a cleaning part is arranged in the second partition area. The cleaning part can clean the rosin remaining on the surface of the coating roller 53 when not in use, ensure the cleanliness of the surface of the coating roller 53, and improve the subsequent coating quality. The cleaning part includes a hollow shell 629 fixed on the second partition area. The shell 629 is through, and an arc-shaped pressing plate two (not shown in the figure) is fixed in the shell 629 by a spring four. The spring four can make the pressing plate two have a certain buffering and resetting ability. The bottom surface of the pressing plate two is fixed with a sponge block two 625. The sponge block two 625 is soft and has good adsorption, which can effectively clean the surface of the coating roller 53. Part of the sponge block two 625 protrudes from the shell 629 and is close to the surface of the coating roller 53. It needs to be explained that the gap between the sponge block two 625 and the coating roller 53 is smaller than the gap between the sponge block one 624 and the coating roller 53, so that the sponge block two 625 can be more closely fitted when contacting the coating roller 53, and the cleaning effect is better. At the same time, an end rod (not shown in the figure) is fixed on the pressing plate two. One end of the end rod is movably penetrated through the coating piece 63 and fixed with a pressing block 623. The surface of the pressing block 623 has an inclined surface. The bottom end of the inclined surface is close to the spherical end of the extrusion rod 617, which facilitates the extrusion operation of the extrusion rod 617.

[0029] And the side of the coating member 63 is provided with a switching part, the switching part is used for switching the action object of the pressing part, and the switching part is used for realizing the conversion of the coating and cleaning functions. The switching part includes an auxiliary plate 619 fixed on the side of the coating member 63, an arch-shaped part 620 fixed on the auxiliary plate 619, and a horizontally arranged air cylinder two 621 fixed on the arch-shaped part 620. The air cylinder two 621 is connected with the side of the mounting box 615 through a connecting panel 622. When the air cylinder two 621 works, the mounting box 615 can be pushed to move. It should be noted that the mounting box 615 is suitable for moving to the top of the cleaning part along with the extension end of the air cylinder two 621. During the movement process, because the contact surface of the pressing part 626 is large, the surface of the pressing part 626 is always in contact with the cam 611, so that the continuity of power transmission is guaranteed. During the movement process, the spherical end of the extrusion rod 617 gradually contacts the pressing block 623, and the pressing block 623 is pressed downward due to the slope of the pressing block 623, and then the end rod drives the pressing plate two to move downward, at this time, the sponge block two 625 is in contact with the surface of the coating roller 53, and the sponge block two 625 is used for cleaning the surface of the coating roller 53.

[0030] As shown in Figures 11-13 A supply assembly 7 is arranged on the side of the fixed sleeve 64. In actual production, the supply assembly 7 can provide rosin solution and cleaning agent for the coating and cleaning processes respectively, so as to guarantee stable material supply of each process. The supply assembly 7 includes a mounting part arranged on the side of the fixed sleeve 64. The mounting part includes a mounting pipe 71 fixed on the side of the fixed sleeve 64, and a storage bottle one 74 and a storage bottle two 75 arranged on the mounting pipe 71 in communication. The storage bottle one 74 stores cleaning agent for cleaning the coating roller 53, and the storage bottle two 75 stores rosin solution for coating operation. The storage bottle one 74 and the storage bottle two 75 are respectively connected with external equipment through a hose, so that the solution can be supplemented, and a liquid level sensor is arranged in the storage bottle one 74 and the storage bottle two 75, so that the solution level in the bottle can be monitored in real time, and the solution can be supplemented in time. A hose one 72 is communicated with the mounting pipe 71.

[0032] Working principle: During operation, the feeding assembly 1 is first activated, and the conveyor continuously transports the copper circuit boards to be processed into the equipment housing 11 of the feeding assembly 1. At this time, the moving module 13 starts working, and its drive element drives the transmission assembly to run, so that the moving parts move smoothly along the guide components. Subsequently, the telescopic end of the cylinder 14 extends, driving the mounting plate and multiple sets of pneumatic grippers 15 on the bottom surface to move down. The pneumatic grippers 15 open and close flexibly to grab the copper circuit boards. After grabbing, the cylinder 14 retracts, and the moving module 13 transports the copper circuit boards to above the conveyor belt 12. The pneumatic grippers 15 release, and the copper circuit boards fall onto the conveyor belt 12, which then transports them to the subsequent pickling assembly 2, washing assembly 3, drying assembly 4, and other processes. In subsequent processes, the copper circuit board passes through the pickling assembly 2, the washing assembly 3, and the drying assembly 4 in sequence. Taking the drying assembly 4 as an example, the copper circuit board enters the outer casing 41 of the equipment. One end of the drying roller 42 is connected to an external heating device to obtain heat flow. After obtaining heat flow, the heat flow is evenly sprayed onto the copper circuit board through the nozzles on the surface. The heat flow quickly evaporates the moisture on the surface of the circuit board, achieving drying. After drying is completed, the conveyor belt 52 smoothly transports the copper circuit board to below the coating roller 53 of the coating assembly 5. Coating assembly 5 begins operation, and the drive unit synchronously drives the coating roller 53 and pressure roller to rotate. Simultaneously, coating assembly 6 operates, with the drive motor driving the lead screw 62 to rotate via a coupling. Since one set of fixed sleeves 64 of the coating component 63 is threadedly connected to the lead screw 62, and another set of fixed sleeves 64 is movably sleeved on the guide rod 61, the coating component 63 moves along the guide rod 61. During the movement of the coating component 63, gear 610 meshes with and rotates with rack 612 on the mounting bracket 51, driving the rotating shaft 69 and cam 611 to rotate. When cam 611 rotates, it pushes the pressure component 626 to move up and down. The pressure component 626 drives the extrusion rod 617 to move. The spherical end of the extrusion rod 617 extrudes the pressure plate 628, compressing the spring. The pressure plate 628 applies pressure to the sponge block 624, causing the rosin solution in the sponge block 624 to pass through the mesh plate 67 and fall onto the surface of the coating roller 53. During its rotation, the coating roller 53 carries rosin solution and, in conjunction with the pressure roller, evenly coats the copper circuit board it passes over with the rosin solution. When the coating component 63 moves to the positions of both ends of the rack 612, the spring 618 is in a naturally extended state, the lowest side of the cam 611 contacts the pressure component 626, and the spherical end of the extrusion rod 617 no longer extrudes the pressure plate 628, stopping the seepage of the rosin solution and avoiding waste.

[0033] When the coating roller 53 needs cleaning, the switching unit is activated, and the telescopic end of cylinder 2 621 pushes the mounting box 615 along the guide rod 614 to move directly above the cleaning section. During the movement, the pressure member 626 remains in contact with the cam 611 to ensure power transmission. The spherical end of the extrusion rod 617 gradually contacts the pressure block 623. Due to the slope on the surface of the pressure block 623, the extrusion rod 617 will press the pressure block 623 downward. The pressure block 623 drives the pressure plate 2 to move downward through the end rod, compressing the spring 4. The pressure plate 2 drives the sponge block 2 625 to contact the surface of the coating roller 53. At this time, the synchronous rotation of the cam 611 pushes the pressure member 626 up and down to squeeze the sponge block 2 625, so that the cleaning agent is maintained. Simultaneously, the rotating part of the supply component 7 is operated, and the movable rod 79 is rotated, causing the movable tube 76 to rotate. This causes the port of storage bottle two 75 to be blocked by the sealing plug 78, and the port of storage bottle one 74 to connect with the first connecting pipe. The cleaning agent in storage bottle one 74 enters the housing 629 through the hose one 72, wetting the sponge block two 625. During the contact process with the coating roller 53, the sponge block two 625 cleans the rosin residue on the surface of the coating roller 53. After cleaning, the cylinder two 621 drives the mounting box 615 to reset, and the rotating part rotates the movable tube 76 back to its initial position, restoring the rosin solution supply. The hook 712 is sleeved on the corresponding protrusion 713 to fix the position of the movable tube 76. The liquid level sensors in storage bottle one 74 and storage bottle two 75 monitor the solution volume in real time to ensure timely replenishment and continuous operation of each process.
