Description

Technical Field

[0001] This application relates to the technical field of PCB board manufacturing and processing, and in particular to an automated device for vertical line production of PCB boards. Background Technology

[0002] PCB (printed circuit board) is an important electronic component. It serves as the support for electronic components, enabling electrical connections between various electronic components in a circuit. It replaces complex wiring, reduces the workload of wiring in traditional methods, simplifies the soldering, assembly, and debugging of electronic products, reduces the size of electronic products, lowers product costs, and improves the reliability and quality of electronic equipment.

[0003] There are two main types of PCB production equipment: horizontal production and vertical production. In vertical production, the PCBs are transported suspended vertically on the equipment and fully immersed in the various processing tanks. This ensures thorough contact between the chemicals in the tanks and the PCBs, resulting in better processing. Vertical production also reduces uneven etching during the etching process, significantly decreasing the number of defective products and improving the PCB yield. In related technologies, PCB loading is typically done manually, where operators pick up the PCBs and suspend them vertically on the production equipment for a series of processing steps.

[0004] Regarding the aforementioned technologies, the inventors believe that relying on manual feeding not only results in high labor costs but also low product production efficiency. Summary of the Invention

[0005] To improve product production efficiency, this application provides an automated device for vertical line production of PCB boards.

[0006] This application provides an automated equipment for vertical line production of PCB boards, which adopts the following technical solution:

[0007] An automated equipment for vertical line production of PCB boards includes a frame, which has a loading area, a unloading area, a temporary storage area and a loading area.

[0008] The clamping mechanism is mounted on the frame and is used to clamp a number of PCB boards. The transport path of the clamping mechanism is along the loading area, unloading area, temporary storage area and waiting loading area.

[0009] The drive mechanism is mounted on the frame and drives the clamping mechanism to reciprocate along the transport path;

[0010] A horizontal transport platform, mounted on the rack, is used for horizontal transport of PCB boards;

[0011] A robotic arm, mounted on a frame, is used to transfer PCBs from a horizontal transport platform to a clamping mechanism for loading, or to transfer PCBs from a clamping mechanism to a horizontal transport platform for unloading.

[0012] By adopting the above technical solution, when the horizontal transport platform transports the PCB board, the robot can transfer the PCB board on the horizontal transport platform to the clamping mechanism located in the loading area for loading; then, the drive mechanism will drive the clamping mechanism to transport from the loading area to the unloading area to complete the processing of the PCB board on the clamping mechanism. The robot in the unloading area can transfer the PCB board on the clamping mechanism to the horizontal transport platform to complete the unloading of the PCB board. Then, the drive mechanism can move the clamping mechanism without clamping the PCB board along the unloading area, temporary storage area, and waiting loading area to the loading area, so that the clamping mechanism can reciprocate along its transport path to complete the automatic processing of the PCB board.

[0013] Compared to traditional technologies where operators pick up PCB boards and suspend them vertically on the PCB production equipment for processing, this application uses a robotic arm to sequentially transfer PCB boards from a horizontal transport platform to a clamping mechanism. This allows the clamping mechanism to hold a number of PCB boards, and a drive mechanism propels the clamping mechanism back and forth along its transport path. This allows the clamping mechanism to complete the processing steps on a number of PCB boards, which are then moved to the unloading area for automatic unloading. They are then transferred along the temporary storage area and the loading area to the loading area. The areas where the clamping mechanism completes processing and the areas where it returns to the loading area do not interfere with each other. This application achieves automated PCB board loading while maintaining high-efficiency PCB board production.

[0014] Optionally, the clamping mechanism includes a mounting plate with a plurality of clamping plates on the mounting plate. Each clamping plate has a clamping assembly for clamping a PCB board at its end. A push plate is slidably disposed on one side of the clamping plate, and a clamping rod is slidably disposed on the other side. A connecting rod is connected to the push plate. The end of the connecting rod away from the push plate passes through the clamping plate and is connected to the clamping rod. The end of the clamping rod away from the connecting rod is connected to the clamping assembly. A driving component is also provided on the mounting plate corresponding to the clamping plate. The driving component is used to drive the push plate to move the clamping rod on the clamping plate, so as to drive the clamping assembly to be in a clamping or open state.

[0015] By adopting the above technical solution, when the robot moves the PCB board onto the clamping mechanism, the driving component can drive the push plate to slide on the clamping plate. Then, the push plate drives the clamping rod to slide on the clamping plate towards the clamping assembly through the connecting rod, so that the end of the clamping rod drives the clamping assembly to be in the open state, so as to prepare to clamp the PCB board; when the clamping rod is away from the clamping assembly, the clamping assembly is in the clamping state, so as to clamp the PCB board.

[0016] Optionally, the clamping assembly includes a first clamping part and a second clamping part, the second clamping part being hinged to the clamping plate, and the end of the clamping rod being hinged to the second clamping part.

[0017] By adopting the above technical solution, since the second clamping part is hinged to the clamping plate, and the end of the clamping rod is hinged to the second clamping part, when the clamping rod slides on the clamping plate toward the second clamping part, the second clamping part will rotate relative to the clamping plate and the clamping rod, so that the second clamping part moves away from the first clamping part, so that the second clamping part and the first clamping part no longer clamp the PCB board; otherwise, the PCB board is clamped.

[0018] Optionally, a limit ring is provided on the clamping rod, and a buffer spring is sleeved on the clamping rod, with one end of the buffer spring abutting against the limit ring and the other end abutting against the clamping plate.

[0019] By adopting the above technical solution, when the clamping rod approaches the clamping assembly, the buffer spring is in a compressed state. Based on the elastic force of the clamping rod away from the clamping assembly, the damage of the clamping rod to the clamping assembly is reduced, thus extending the service life of the clamping assembly.

[0020] Optionally, the driving mechanism includes a crane assembly for driving the clamping mechanism from the loading area to the unloading area, and the number of crane assemblies is at least one; the frame has a transport track along the direction from the loading area to the unloading area for the crane assembly to move; the crane assembly includes a crane frame and a moving frame, the moving frame is arranged outside the crane frame along the direction of the transport track and is perpendicular to the crane frame; the moving frame is also provided with a transverse part, the transverse part includes a transverse motor and a transverse wheel, the transverse wheel is rotatably mounted on the moving frame and is rolledly connected to the transport track, and the transverse motor is mounted on the moving frame for driving the transverse wheel to rotate.

[0021] By adopting the above technical solution, since there are many processing steps for PCB boards, the number of overhead crane components can be multiple, which can effectively improve the processing efficiency of PCB boards; the frame has a transport track for the overhead crane components to move along the direction from the loading area to the unloading area. The transverse motor on the moving frame of the overhead crane is started, driving the transverse wheel on the transverse frame to rotate, so that the transverse wheel can roll along the transport track, realizing the movement of the overhead crane components on the frame.

[0022] Optionally, the frame has a number of processing slots for processing PCB boards, and the overhead crane frame is also equipped with a lifting unit for lowering or raising the PCB board on the clamping mechanism into or from the processing slot to facilitate PCB board processing; the lifting unit includes a lifting motor, a lifting rod, a lifting wheel, a lifting belt, and a lifting plate; the lifting motor is mounted on the overhead crane frame, one end of the lifting rod is drivenly connected to the lifting motor, and the other end is rotatably connected to the overhead crane frame; the lifting plate is slidably mounted on the overhead crane frame along the direction close to or away from the processing slot, the lifting wheel is sleeved on the lifting rod, one end of the lifting belt is fixedly connected to the lifting wheel, and the other end is connected to the lifting plate; the lifting plate is also equipped with a lifting hook, and the mounting plate is also equipped with a connecting frame, the lifting hook and the connecting frame being detachably connected.

[0023] By adopting the above technical solution, when a number of PCB boards are clamped on the clamping mechanism, the transverse part drives the overhead crane assembly to approach the clamping mechanism. Then, the lifting hook on the lifting plate is connected to the connecting frame on the mounting plate, so that the clamping mechanism is located on the lifting plate of the overhead crane assembly. When the PCB board on the clamping mechanism needs to be processed, the lifting motor is started, driving the lifting rod to rotate, so that the lifting wheel on the lifting rod rotates. The lifting belt wound on the lifting wheel is released by a certain length, so that the lifting plate moves along the direction close to the processing tank, so that the PCB board on the clamping mechanism can be located in the processing tank for processing.

[0024] Optionally, both ends of the lifting plate are connected to sliding plates, and each sliding plate is rotatably connected to a lifting guide wheel. The overhead crane frame is provided with a guide and limiting rail along the sliding direction of the lifting plate to allow the lifting guide wheel to roll, thereby improving the stability of the lifting plate sliding on the overhead crane frame.

[0025] By adopting the above technical solution, the lifting guide wheel can play a guiding role, allowing the lifting plate to slide on the overhead crane along the direction close to the processing tank; and the setting of the guide limit rail can limit the rolling path of the lifting guide wheel on the one hand, and reduce the slippage of the lifting guide wheel on the other hand, thereby reducing the deviation of the lifting plate when sliding on the overhead crane and improving the stability of the lifting plate when sliding on the overhead crane.

[0026] Optionally, anti-collision mechanisms are provided on both sides of the movable frame, and the anti-collision mechanisms are arranged along the moving direction of the movable frame; the anti-collision mechanism includes a mounting base, a sliding rod, an anti-collision spring, and a baffle. One end of the sliding rod is connected to the baffle, and the other end is slidably connected to the mounting base. A sensing block is also sleeved on the sliding rod. The mounting base is disposed on the movable frame, and the mounting base has a sliding groove for the sensing block to move. A sensor is provided on the inner wall of the sliding groove. The anti-collision spring is sleeved on the sliding rod, and one end of the anti-collision spring abuts against the outer wall of the mounting base, and the other end abuts against the baffle.

[0027] By adopting the above technical solution, when the crane components collide unexpectedly, the baffle is impacted, causing the sliding rod to slide on the mounting base. At the same time, the sensing block located in the sliding groove will come into contact with the sensor, which can provide feedback on the collision situation to control the crane components to prevent further collisions. When the sliding rod slides on the mounting base, the anti-collision spring will also be compressed. Based on the elastic force of the baffle away from the mounting base, the collision between the baffle and the mounting base is reduced, and the impact force on the sensor from the sensing block is also reduced.

[0028] Optionally, the driving mechanism includes a rack assembly for driving the clamping mechanism from the temporary storage area to the loading area. The rack assembly includes a transport component, rolling wheels, and a rack track arranged along the direction of the temporary storage area toward the loading area. The rolling wheels are rotatably connected to the mounting plate and are arranged on the rack track along the length of the rack track. The transport component is used to drive the rolling wheels to roll on the rack track so that the clamping mechanism moves along the direction of the rack track.

[0029] By adopting the above technical solution, when the clamping mechanism needs to move from the temporary storage area to the loading area, the transport component can drive the rolling wheel to roll on the hanger track, so that the clamping mechanism moves along the setting direction of the hanger track.

[0030] Optionally, the drive mechanism further includes a lifting assembly mounted on the frame. There are two lifting assemblies, one of which drives the clamping mechanism from the loading area to the loading area, and the other drives the clamping mechanism from the unloading area to the temporary storage area. Each lifting assembly includes a lifting component, a lifting guide plate, and a lifting carrier. The lifting guide plate is mounted on the frame, and the lifting carrier is slidably mounted on the lifting guide plate for driving the clamping mechanism to move along the lifting guide plate. The lifting component is mounted on the frame and drives the lifting carrier to slide along the lifting guide plate.

[0031] By adopting the above technical solution, when the clamping mechanism needs to be driven from the loading area to the loading area, or from the unloading area to the temporary storage area, the clamping mechanism is located on the lifting frame, and then the lifting component can drive the lifting frame to slide back and forth on the lifting guide plate to achieve the driving of the clamping mechanism.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This application enables a robotic arm to sequentially transfer PCB boards from a horizontal transport platform to a clamping mechanism, allowing the clamping mechanism to hold a number of PCB boards. The drive mechanism then drives the clamping mechanism to reciprocate along the transport path of the clamping mechanism, enabling the clamping mechanism to hold a number of PCB boards to complete the processing steps. The boards are then moved to the unloading area for automatic unloading, and then transported along the temporary storage area and the loading area to the loading area. The area where the clamping mechanism holds the PCB boards for processing and the area where the clamping mechanism returns to the loading area do not interfere with each other. This application has the effect of automating PCB board loading while maintaining high-efficiency PCB board production.

[0034] 2. The push plate drives the clamping rod to slide on the clamping plate towards the clamping assembly via the connecting rod, so that the end of the clamping rod drives the clamping assembly to be in the open state, so as to prepare to clamp the PCB board; when the clamping rod moves away from the clamping assembly, the clamping assembly is in the clamping state, so as to clamp the PCB board.

[0035] 3. The transverse motor on the moving frame of the overhead crane starts, driving the transverse wheels on the transverse frame to rotate, so that the transverse wheels can roll along the transport track, realizing the movement of the overhead crane components on the frame;

[0036] 4. When the PCB board on the clamping mechanism needs to be processed, the lifting motor starts and drives the lifting rod to rotate, so that the lifting wheel on the lifting rod rotates. The lifting belt wound on the lifting wheel is released by a certain length, so that the lifting plate moves along the direction close to the processing tank, so that the PCB board on the clamping mechanism can be located in the processing tank for processing.

[0047] The present application will be further described in detail below with reference to the accompanying drawings.

[0048] This application discloses an automated device for producing vertical lines on a PCB board. (Refer to...) Figure 1 and Figure 2The automated equipment for vertical PCB production includes a frame 1 and a horizontal transport platform 4, a robotic arm 5, a clamping mechanism 2, a drive mechanism 3, a washing mechanism 6, and a drying mechanism 7, all mounted on the frame 1. The frame 1 has a loading area 11, a unloading area 12, a temporary storage area 13, and a loading area 14. The clamping mechanism 2 is transported along the loading area 11, unloading area 12, temporary storage area 13, and loading area 14. The drive mechanism 3 drives the clamping mechanism 2 to move cyclically along the transport path. The horizontal transport platform 4 has rollers for transporting the PCBs. There are two horizontal transport platforms 4: one located in the loading area 11 to transport the PCBs to the loading area 11, and the other located in the unloading area 12 to remove the PCBs from the unloading area 12. There are two robotic arms 5. One is located in the loading area 11 and is used to transfer the PCB board on the horizontal transport platform 4 to the clamping mechanism 2 located in the loading area 11. The other is located in the unloading area 12 and is used to transfer the PCB board on the clamping mechanism 2 located in the unloading area 12 to the horizontal transport platform 4.

[0049] Reference Figure 2 and Figure 3 The clamping mechanism 2 includes a mounting plate 21, on which a plurality of clamping plates 211 are screwed and arranged parallel to each other. In this embodiment, 12 clamping plates 211 are used, arranged in pairs on the mounting plate 21, for a total of six groups, with the six groups evenly spaced. A push plate 212 and a clamping rod 213 are slidably disposed on both sides of each clamping plate 211, with the sliding direction being the length direction of the clamping plate 211. A clearance hole (not shown in the figure) is also provided on the clamping plate 211 along the sliding direction of the push plate 212. A connecting rod 2121 is screwed to the side of the push plate 212 facing the clamping plate 211, and the end of the connecting rod 2121 away from the push plate 212 passes through the clearance hole and is screwed to the clamping rod 213. The mounting plate 21 is also provided with a drive component 214 by screws. In this embodiment, the drive component 214 is a drive cylinder. The piston rod of the drive cylinder is connected to the end of the push plate 212 away from the clamping plate 211 by screws. The drive component 214 can drive the push plate 212 to slide on the clamping plate 211, thereby driving the clamping rod 213 to slide on the clamping plate 211.

[0050] Each clamping plate 211 has a clamping assembly 22 at its end, which is used to clamp the end of the PCB board. The clamping assembly 22 includes a first clamping part 221 and a second clamping part 222. In this embodiment, both the first clamping part 221 and the second clamping part 222 are plate-shaped structures. The clamping plate 211 has a fixing block 2111, and the second clamping part 222 is hinged to the fixing block 2111. One end of the first clamping part 221 is connected to the clamping plate 211 by a screw. Both the first clamping part 221 and the second clamping part 222 have clamping ends on opposite sides. The clamping ends are used to abut against the PCB board and clamp the PCB board. The end of the second clamping part 222 away from its clamping end is also hinged to the end of the clamping rod 213 through the fixing block 2111. When the driving member 214 drives the clamping rod 213 to slide closer to the clamping assembly 22, the second clamping part 222 rotates relative to the fixing block 2111 and the end of the clamping rod 213, so that the clamping end of the second clamping part 222 moves away from the clamping end of the first clamping part 221, thereby releasing the clamping state on the PCB board. A limiting ring 2131 is also sleeved on the clamping rod 213, and a buffer spring 2132 is sleeved on the clamping rod 213. One end of the buffer spring 2132 is bonded to the limiting ring 2131, and the other end is bonded to the outer wall of the fixing block 2111.

[0051] The robotic arm 5 is fixed to the frame 1 by screws, and the robotic arm 5 has a suction cup 51. The suction cup 51 can adsorb the PCB board and then transfer the PCB board to each clamping component 22 in turn so that the clamping component 22 can clamp the PCB board.

[0052] Reference Figure 2 and Figure 4The frame 1 has a transport track 15 along the upper edge of the loading area 11 near the unloading area 12, and a number of processing slots 16 for processing PCB boards are sequentially arranged along the upper edge of the loading area 11 near the unloading area 12. Each processing slot 16 is located below the transport track 15. The drive mechanism 3 includes a crane assembly 31. The number of crane assemblies 31 is at least one. In this embodiment, there are two crane assemblies 31, both of which reciprocate on the transport track 15. The crane assembly 31 includes a crane frame 311, a moving frame 312, a lateral movement part 314, and a lifting part 315. In this embodiment, the crane frame 311 has an inverted "U" shape, and the opening of the crane frame 311 faces the processing slot 16. In this embodiment, the width of the crane frame 311 is smaller than the width of the transport track 15 so that the crane frame 311 can be transported between the transport tracks 15. The movable frame 312 is screwed to the outside of the overhead crane frame 311 and is arranged along the direction of the transport track 15. In this embodiment, the movable frame 312 has a rectangular structure, and its width is not less than the width of the transport track 15. A movable part is provided on the movable frame 312 to drive the movable frame 312 to reciprocate along the transport track 15. A lifting part 315 is provided on the overhead crane frame 311 to lower the PCB board on the clamping mechanism 2 into the processing slot 16 for processing. After processing, the clamping mechanism 2 is raised and moved laterally to the top of the next processing slot 16 via the transverse part 314, and then lowered into the processing slot 16 again, and so on.

[0053] Reference Figure 4 and Figure 5The lifting unit 315 includes a lifting motor 3151, a lifting rod 3152, lifting wheels 3153, and a lifting plate 3155. The lifting motor 3151 is mounted on the overhead crane frame 311 by screws. The lifting rod 3152 is mounted on the overhead crane frame 311, with one end connected to the output shaft of the lifting motor 3151 and the other end rotatably connected to the overhead crane frame 311. In this embodiment, two lifting wheels 3153 are used, and both lifting wheels 3153 are sleeved on the lifting rod 3152. Each lifting wheel 3153 is fixedly connected to a lifting belt 3154, which is wound around the lifting wheel 3153. The lifting plate 3155 is slidably mounted on the overhead crane frame 311, with the sliding direction being towards or away from the processing tank 16. Both ends of the lifting plate 3155 are connected to sliding plates 3111 by screws, and each sliding plate 3111 is rotatably connected to a lifting guide wheel 3112. The overhead crane frame 311 has a guide rail (not shown in the figure) along the sliding direction of the lifting plate 3155 for the lifting guide wheel 3112 to roll. The lifting guide wheel 3112 can roll in the guide rail to reduce the tilting of the lifting plate 3155 when it slides. The lifting plate 3155 is provided with a fixed wheel 31552 corresponding to the lifting wheel 3153. The end of the lifting belt 3154 wound on the lifting wheel 3153 passes through the fixed wheel 31552 and is bonded to the lifting belt 3154. The welded joint is fixed by the fixing frame 31553.

[0054] Reference Figure 3 and Figure 4 A lifting hook 31551 is connected to the lifting plate 3155 by screws, and a connecting frame 215 is connected to the mounting plate 21 by screws. The connecting frame 215 has a spacing to facilitate the passage of the lifting hook 31551. The connecting frame 215 also has a connecting block 2151 that abuts against the lifting hook 31551. When the lifting hook 31551 is located within the spacing on the connecting frame 215, the connecting block 2151 corresponds to the lifting hook 31551. When the lifting part 315 drives the lifting plate 3155 to rise, the lifting hook 31551 can abut against the connecting block 2151, so that the lifting part provides a lifting force on the connecting block 2151, so that the clamping mechanism 2 can be raised.

[0055] In this embodiment, there are two transverse moving parts 314, which are disposed at both ends of the movable frame 312 to drive the movable frame 312 to move on the transport track 15. The transverse moving part 314 includes a transverse moving motor 3141 and a transverse moving wheel 3142. The transverse moving motor 3141 is mounted on the movable frame 312 by screws. A transverse moving rod is also rotatably mounted on the movable frame 312. Both ends of the transverse moving rod are connected to the transverse moving wheel 3142. The transverse moving wheel 3142 can roll on the transport track 15. The transverse moving motor 3141 is connected to the transverse moving rod through gear meshing to drive the transverse moving wheel 3142 to rotate, thereby enabling the movable frame 312 to move on the transport track 15.

[0056] Reference Figure 5 The movable frame 312 is provided with an anti-collision mechanism 313. In this embodiment, two anti-collision mechanisms 313 are used, and they are respectively arranged on the front and rear sides of the movable frame 312 along the moving direction of the movable frame 312. The anti-collision mechanism 313 includes a mounting base 3131, a sliding rod 3132, an anti-collision spring 3133, and a baffle 3134. One end of the sliding rod 3132 is connected to the baffle 3134, and the other end is slidably connected to the mounting base 3131. A sensing block 31321 is also sleeved on the sliding rod 3132. The mounting base 3131 is set on the movable frame 312 by screws, and the mounting base has a sliding groove 31311 for the sensing block 31321 to move. A sensor 31312 is also set on the inner wall of the sliding groove 31311 by screws. The anti-collision spring 3133 is sleeved on the sliding rod 3132, and one end of the anti-collision spring 3133 abuts against the outer wall of the mounting base 3131, and the other end abuts against the baffle 3134.

[0057] Reference Figure 2 and Figure 6The drive mechanism 3 also includes a lifting assembly 32. In this embodiment, two lifting assemblies 32 are used: one to drive the clamping mechanism 2 from the loading area 14 to the loading area 11, and the other to drive the clamping mechanism 2 from the unloading area 12 to the temporary storage area 13. The lifting assembly 32 includes a lifting member 321, a lifting guide plate 322, and a lifting carrier 323. In this embodiment, the lifting member 321 is a drive motor, and it is screwed onto the frame 1. The lifting guide plate 322 is screwed onto the frame 1, and the lifting carrier 323 is slidably mounted on the lifting guide plate 322. A guide groove is formed along the length of the lifting guide plate 322, and a guide block is provided on the lifting carrier 323. The guide block slides in the guide groove to achieve a sliding connection between the lifting carrier 323 and the lifting guide plate 322. A lifting cable 324 is wound around the output shaft of the lifting component 321. A guide wheel 325 is screwed onto the frame 1, and the lifting cable 324 is connected to the lifting carrier 323 via the guide wheel 325. When the lifting component 321 rotates, it can release or retract the length of the lifting cable 324, causing the lifting cable 324 to drive the lifting carrier 323 to slide back and forth on the lifting guide plate 322. The lifting carrier 323 has a support plate 3231. When the clamping mechanism 2 is located on the lifting carrier 323, the mounting plate 21 of the clamping mechanism 2 is located above the support plate 3231, so that the lifting carrier 323 supports the clamping mechanism 2.

The hanger assembly 33 includes a transport component (not shown in the figure), a rolling wheel 332, and a hanger track 331 arranged along the direction of the temporary storage area 13 towards the loading area 14. The rolling wheel 332 is rotatably mounted on the hanger track 331. In this embodiment, the transport component is a drive motor, which is screwed onto the frame 1 to drive the rolling wheel 332 to roll on the hanger track 331. On the side of the mounting plate 21 away from the connecting frame 215, there are four limiting rolling plates 216 arranged in pairs and rotatably connected to the rolling wheel 332. The limiting rolling plate 216 has a limiting plate 2161, which is located on the outside of the limiting rolling plate 216, so that the rolling wheel 332 is located between the two limiting plates 2161, reducing the possibility of the mounting plate 21 slipping off the rolling wheel 332.

[0059] Reference Figure 2 and Figure 8A discharge plate 17 is screwed onto the frame 1 near the unloading area 12. The discharge plate 17 has vertically arranged transport rollers 171. When the PCB board is transported from the rollers on the horizontal transport platform 4 of the unloading area 12 to the discharge plate 17, the PCB board is positioned between the vertical rows of transport rollers 171, thus clamping the PCB board between them. A washing mechanism 6 and a drying mechanism 7 are sequentially arranged on the discharge plate 17 along the transport direction of the PCB board.

[0060] The washing mechanism 6 includes a washing body 61 and spray nozzles 62. The washing body 61 is placed on a flat surface, and the discharge plate 17 passes through the washing body 61. A number of spray nozzles 62 are screwed onto the washing body 61. In this embodiment, sixteen spray nozzles 62 are used, arranged in two groups of eight spaced apart side-by-side. The two groups of spray nozzles 62 are located on both sides of the transport rollers 171 to facilitate rinsing of the PCB boards held and transported by the transport rollers 171, achieving a uniform rinsing effect. The drying mechanism 7 includes a drying body 71, a cooling air assembly 72, and a heating air assembly 73. The drying body 71 is placed on a flat surface, and the discharge plate 17 passes through the drying body 71.

[0061] Reference Figure 8 and Figure 9 The cooling air assembly 72 and the heating air assembly 73 are sequentially arranged on the dry board body 71 according to the transport direction of the PCB board. The cooling air assembly 72 includes a cooling air pump 721 and a cooling air nozzle 722. The cooling air pump 721 is mounted on the dry board body 71 by screws. In this embodiment, the cooling air pump 721 used is a high-power cooling air pump 721, which is used to make the gas ejected by the cooling air nozzle 722 faster. In this embodiment, there are six cooling air nozzles 722, and three cooling air nozzles 722 are arranged side by side and spaced apart between the transport rollers 171 to form a group, for a total of two groups. The two groups of cooling air nozzles 722 are located on both sides of the PCB board. Each cooling air nozzle 722 has two air outlets 7221. One air outlet 7221 is set directly facing the PCB board, and the other air outlet 7221 is set at an angle to facilitate blowing water on the PCB board in the opposite direction of the PCB board transport direction.

[0062] The hot air assembly 73 includes a hot air pump 731 and hot air nozzles 732. The hot air pump 731 is screwed onto the dry board body 71 and is used to spray hot air from the hot air nozzles 732 to dry the PCB board. In this embodiment, ten hot air nozzles 732 are used, arranged in two groups of five side-by-side at intervals. The two groups of hot air nozzles 732 are located on opposite sides of the PCB board. Each hot air nozzle 732 has an outlet 7321, which is located between the transport rollers 171 to facilitate the blowing of hot air onto the PCB board for drying.

[0063] The implementation principle of an automated PCB vertical line production equipment according to an embodiment of this application is as follows: The horizontal transport platform 4 transports the PCB board to the loading area 11. At this time, the clamping mechanism 2 is located in the loading area 11, and the drive component 214 drives each clamping component 22 on the mounting plate 21 to be in the open state. Then, the robot arm 5 uses the suction cup 51 to pick up the PCB board one by one, and then transfers it to the clamping component 22 on the clamping mechanism 2. Then, the drive component 214 drives each clamping component 22 to clamp each PCB board. Then, the overhead crane assembly 31 is driven to the loading area 11 by the transverse part 314. At this time, the lifting motor 3151 drives the lifting plate 3155 to move down, and then the lifting hook 31551 just abuts against the connecting block 2151. Then, the lifting motor 3151 drives the lifting plate 3155 to rise and lift the clamping mechanism 2. Then, the transverse part 314 drives the overhead crane frame 311 to the upper part of the processing tank 16. Next, the lifting motor 3151 drives the clamping mechanism 2 to descend, so that the PCB board on the clamping mechanism 2 is located in the processing tank 16 for processing. After processing, the lifting motor 3151 drives the lifting plate 3155 to drive the clamping mechanism 2 back to its original position. This process continues until the PCB board is processed. Then, the overhead crane assembly 31 transports the clamping mechanism 2 to the unloading area 12. The robot arm 5 on the unloading area 12 uses the suction cup 51 to transfer the PCB boards on the clamping mechanism 2 one by one to the horizontal transport platform 4 for water washing and drying. Then, the clamping mechanism 2 is moved from the unloading area 12 to the temporary storage area 13 by the lifting assembly 32. Then, the hanging assembly 33 moves the clamping mechanism 2 from the temporary storage area 13 to the loading area 14. Then, the lifting assembly 32 moves the clamping mechanism 2 from the loading area 14 to the loading area 11. The clamping assembly 22 moves repeatedly to clamp the PCB board.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
