Description

Technical Field

[0001] The present invention relates to the technical field of PCB board processing, and in particular to a fully automatic integrated vacuum plugging machine. Background Art

[0002] During the processing of PCB boards, processes such as plugging holes and ink scraping are usually required.

[0003] Existing PCB via plugging machines are typically only capable of performing the via plugging process, not the squeegee process. The squeegee process, however, requires the squeegee machine to complete the PCB via plugging process. Specifically, during the PCB via plugging process, the PCB must be manually placed into the via plugging machine, where it is clamped by a clamping mechanism within the machine for the via plugging process. After the via plugging process is complete, the PCB is manually removed from the via plugging machine and placed into the squeegee machine, where it is clamped by a clamping mechanism within the machine for the squeegee process.

[0004] In summary, in the prior art, the plugging and scraping processes of PCB boards cannot be completed centrally on a plugging machine. Furthermore, during the plugging and scraping processes, the PCB boards need to be manually placed in the clamping mechanism of the plugging or scraping machine. During the manual transfer of the PCB boards, workers may become fatigued, making it impossible to ensure the efficiency, quality, and yield of the plugging and scraping processes of the PCB boards. Summary of the Invention

[0005] In response to the shortcomings of the prior art, one of the objectives of the present invention is to provide a fully automatic integrated vacuum plugging machine, which aims to solve the technical problem that the plugging and ink scraping processes of PCB boards cannot be completed centrally on the plugging machine, and that the efficiency, quality and yield of the plugging and ink scraping processes of PCB boards cannot be guaranteed due to worker fatigue when manually transferring PCB boards from the plugging process to the ink scraping process.

The ink scraping chamber is fixed to the base frame and is spaced apart from the plug hole cavity along the horizontal direction of the base frame. The clamping mechanism B is arranged in the ink scraping chamber. The structure of the clamping mechanism B is the same as that of the clamping mechanism A. The lifting device B is arranged on the ink scraping chamber and is used to drive the ink scraping assembly to rise and fall in the ink scraping chamber.

[0011] The transfer mechanism includes a linear drive module and a loading assembly. The linear drive module is arranged on the top outside the plug hole cavity and the ink scraper bin along the horizontal direction of the base frame. The linear drive module is used to drive the loading assembly to move horizontally. The loading assembly is used to clamp and transport the PCB board to the clamping channel.

[0012] Furthermore, the loading assembly includes a clamping assembly, which is used to clamp the PCB board to be plugged or to be scraped.

[0013] Furthermore, the loading assembly also includes a pushing assembly, which is arranged along the longitudinal direction of the base frame. The pushing assembly is connected to the linear drive module and the clamping assembly. The pushing assembly is used to push the clamping assembly into the plug hole cavity or the ink scraping bin. The pushing assembly is also used to push the clamping assembly out of the plug hole cavity or the ink scraping bin.

[0014] Furthermore, the pushing assembly includes a fixed seat, a movable seat and a driving unit. The fixed seat extends in a vertical direction. One end of the fixed seat is drive-connected to the linear drive module. Guide blocks are provided on opposite sides of the other end of the fixed seat. Slide rails are fixed on opposite sides of the movable seat. The slide rails extend along the longitudinal direction of the base frame. The slide rails slide relative to the guide blocks. The driving unit is provided on the movable seat and drive-connected to the clamping assembly. The driving unit is used to drive the clamping assembly to move along the longitudinal direction of the base frame.

[0015] Furthermore, an anti-falling plate is provided on the movable seat to prevent the PCB board clamped by the clamping assembly from falling.

[0016] Furthermore, the clamping assembly includes a connecting plate, a driving mechanism and two feeding width adjustment plates, the connecting plate extends laterally along the base frame, the connecting plate is fixed on the movable seat, the two feeding width adjustment plates are arranged at both ends of the connecting plate laterally along the base frame, the driving mechanism is arranged on the connecting plate, and the driving mechanism is used to drive the two feeding width adjustment plates to move toward or away from each other.

[0019] Furthermore, the inking assembly further comprises a linear moving module, which is arranged on the top outside the ink scraping bin and is used to drive the two connecting members to move laterally along the base frame.

[0020] Furthermore, each of the connecting members is provided with a telescopic mechanism, a telescopic end of each of the telescopic mechanisms extends longitudinally along the base frame, and a telescopic end of each of the telescopic mechanisms is drive-connected to each of the ink extruders.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] When the fully automatic integrated vacuum plugging machine of the present invention is in use, the PCB board to be plugged can be automatically loaded onto the loading assembly by the manipulator, and then the loading assembly is driven by the linear drive module to move along the horizontal direction of the base frame to the position corresponding to the plugging cavity, and then the loading assembly extends the PCB board clamped by itself into the plugging cavity. At this time, the lifting unit of the clamping mechanism A drives the lifting plate to rise, avoiding the loading assembly to transport the PCB board along the longitudinal direction of the base frame to the point where it abuts against the clamping plate of the clamping mechanism A; when the loading assembly transports the PCB board to the point where it abuts against the clamping plate of the clamping mechanism A, The lifting unit of the clamping mechanism A drives the lifting plate of the clamping mechanism A to descend, and the telescopic units of the clamping mechanism A drive the clamping claws of the clamping mechanism A to move along the longitudinal direction of the base frame toward the clamping plate of the clamping mechanism A, thereby clamping and fixing the PCB board in the clamping channel of the clamping mechanism A; then, the plugging cavity is closed to make the inner cavity of the plugging cavity in a closed state, and the plugging cavity is vacuumed by the vacuum device, and at the same time, the plug assembly is driven up and down by the lifting device A, so that the ink sprayed from the plug of the plug assembly plugs the PCB board clamped and fixed by the clamping mechanism A.

[0023] When the plugging action of the PCB board is completed, the plugging cavity is opened, and the loading assembly extends into the plugging cavity to clamp and fix the PCB board clamped by the clamping mechanism A. At this time, the lifting unit of the clamping mechanism A drives the lifting plate to rise, and then the loading assembly extends out of the plugging cavity along the longitudinal direction of the base frame, and then the linear drive module drives the loading assembly to move horizontally along the base frame to the position of the scraper bin. At this time, the loading assembly clamps the plugged PCB board and transports it to the scraper bin along the longitudinal direction of the base frame. At this time, the lifting unit of the clamping mechanism B drives the lifting plate to rise to avoid the loading assembly. The PCB board is transported along the longitudinal direction of the base frame to the point where it abuts against the clamping plate of the clamping mechanism B; when the loading assembly transports the PCB board to the point where it abuts against the clamping plate of the clamping mechanism B, the lifting unit of the clamping mechanism B drives the lifting plate of the clamping mechanism B to descend, and the telescopic units of the clamping mechanism B drive the clamping claws of the clamping mechanism B to move along the longitudinal direction of the base frame toward the clamping plate of the clamping mechanism B, thereby clamping and fixing the PCB board in the clamping channel of the clamping mechanism B; at this time, the ink scraping assembly is driven up and down by the lifting device B to scrape ink from the PCB board clamped and fixed on the clamping mechanism B.

[0024] In summary, the fully automatic integrated vacuum plugging machine of the present invention can automatically complete the plugging and ink scraping processes of the PCB board. At the same time, the PCB board can be moved to the clamping mechanism of the plugging device or the clamping mechanism of the ink scraping device through the transfer mechanism, and the loading action of the PCB board plugging process or the ink scraping process can be automatically completed, thereby ensuring the efficiency, quality and yield of the PCB board plugging process and the ink scraping process.

[0053] Please refer to Figure 1-Figure 23 The present invention provides a fully automatic integrated vacuum plugging machine, including a base frame 1, a plugging device 2, an ink scraping device 3 and a transfer mechanism 4.

[0054] Reference Figure 1 - Figure 13 The plugging device 2 includes a plugging cavity 20, a clamping mechanism A21, a lifting device A23 and a plug head assembly 22. The plugging cavity 20 is fixed on the base frame 1, and the inner cavity of the plugging cavity 20 is connected to the vacuum device 6 provided outside the plugging cavity 20. A door 201 is provided on the rear side of the plugging cavity 20, and the door 201 is equipped with an automatic lifting door 202, which is used to close the door 201. Of course, the vacuum device 6 can draw a vacuum from the inner cavity of the plugging cavity 20. When it is necessary to draw a vacuum from the inner cavity of the plugging cavity 20, the door 201 of the plugging cavity 20 is closed by the automatic lifting door 202.

[0055] The automatic lifting door 202 adopts the existing automatic lifting door structure, which will not be described in detail here.

[0056] Reference Figure 4 and Figure 11-13The clamping mechanism A21 is disposed within the plug hole cavity 20 and includes a clamping plate 210, a lifting plate 212, and a plurality of telescopic units 213. The clamping plate 210 is fixed to the top of the plug hole cavity 20. Lifting units 2120 are fixed to the left and right ends of the clamping plate 210. The lifting ends of the lifting units 2120 are connected to the lifting plate 212. The plurality of telescopic units 213 are disposed on the lifting plate 212. The telescopic ends of the telescopic units 213 are connected to clamping claws 214. A clamping channel 215 is formed between the plurality of clamping claws 214 and the clamping plate 210. The clamping channel 215 is primarily used to clamp and secure the PCB board 8 to be plugged.

[0057] In this embodiment, the telescopic unit 213 is a telescopic cylinder; the lifting unit 2120 is a lifting cylinder; in other embodiments, the telescopic unit 213 or the lifting unit 2120 can also be an electric push rod.

[0058] Reference Figure 4 and Figure 6 The lifting device A23 is provided on the plug hole cavity 20, and is used to drive the plug head assembly 22 to move up and down in the plug hole cavity 20. Specifically, the lifting device A23 includes a lifting power assembly 230 and a screw mechanism 231. The lifting power assembly 230 is provided on the top surface outside the plug hole cavity 20. The screw A24 of the screw mechanism 231 is connected to the lifting power assembly 230 by driving, and the screw A24 of the screw mechanism 231 is provided in the plug hole cavity 20. Of course, both ends of the mounting seat 220 are provided with the above-mentioned screw mechanisms 231, and the two ends of the mounting seat 220 are respectively connected to the screw A24 of the two screw mechanisms 231 by driving. In this way, by driving the screw A24 of each screw mechanism 231 to rotate by the lifting power assembly 230, the mounting seat 220 can be driven to move up and down in the vertical direction, thereby achieving the purpose of the lifting device A23 driving the plug head assembly 22 to move up and down in the plug hole cavity 20. Of course, in other embodiments, the lifting device A23 may also be an electric push rod or a linear module, which is not limited here.

[0059] Reference Figure 4 and Figures 6-10 The plug assembly 22 is disposed at the bottom of the plug hole cavity 20; the plug assembly 22 is provided with a plug. The plugs are a front plug 2211 and a rear plug 2221, respectively. The front plug 2211 and the rear plug 2221 are connected to a negative pressure ink conduit outside the plug hole cavity 20. The front plug 2211 and the rear plug 2221 are used to fill ink into the hole of the PCB board clamped by the clamping mechanism A. The negative pressure ink conduit is connected to an ink supply device 7 disposed outside the plug hole cavity 20, and ink is supplied to the plugs through the ink supply device 7. The ink supply device 7 uses an existing ink supply structure, and its specific structure is not described here.

[0060] Reference Figures 6-10The plug assembly 22 of this embodiment includes a mounting seat 220, a front plug component 221 and a rear plug component 222. The left and right ends of the mounting seat 220 are respectively connected to the lifting device A23, and the mounting seat 220 can be lifted and lowered in the vertical direction through the lifting device A23.

[0061] Reference Figure 4 and Figures 6-10 The front plug component 221 includes a front mounting plate 2210 and the above-mentioned front plug 2211, and the rear plug component 222 includes a rear mounting plate 2220 and the above-mentioned rear plug 2221. The front mounting plate 2210 and the rear mounting plate 2220 are relatively fixed on the mounting seat 220 along the longitudinal direction of the low frame. The plug of the front plug component 221 is fixed on the side of the front mounting plate 2210 facing the rear mounting plate 2220, and the plug of the rear plug component 222 is fixed on the side of the front mounting plate 2210 facing the rear mounting plate 2220. Fixed on the side of the rear mounting plate 2220 facing the front mounting plate 2210, an ink plug channel 2223 is formed between the front plug head 2211 and the rear plug head 2221, and the ink plug channel 2223 passes through the relative surface of the mounting seat 220. The ink plug channel 2223 is located directly below the clamping channel 215 of the clamping mechanism A21. The inner diameter of the ink plug channel 2223 is greater than the thickness of the PCB board 8, so that the ink plug channel 2223 can accommodate the PCB board 8. When performing the plugging process of the PCB board 8, the automatic lifting door 202 closes the door 201 of the plugging cavity 20, and the inner cavity of the plugging cavity 20 is vacuumed. The PCB board 8 is clamped and fixed in the clamping channel 215 of the clamping mechanism A21. The ink supply device 7 supplies ink to the front plug 2211 and the rear plug 2221 through the ink negative pressure pipeline. At the same time, the plug assembly 22 is driven up and down by the lifting device A23, so that the front plug 2211 and the rear plug 2221 fill the ink into the hole on the PCB board 8, thereby completing the plugging process of the PCB board 8.

[0062] Reference Figure 4 and Figures 6-10 The front plugging head component 221 further includes a telescopic cylinder A2212 for driving the front mounting plate 2210 to move along the longitudinal direction of the base frame 1 toward or away from the rear mounting plate 2220. Multiple telescopic cylinders A2212 are provided, and each of these cylinders A2212 is fixed within the plugging hole cavity 20. Similarly, the rear plugging head component 222 further includes a telescopic cylinder B2222 for driving the rear mounting plate 2220 to move along the longitudinal direction of the base frame 1 toward or away from the front mounting plate 2210. Multiple telescopic cylinders B2222 are provided, and each of these cylinders B2222 is fixed within the plugging hole cavity 20. Therefore, the spacing between the front mounting plate 2210 and the rear mounting plate 2220 is adjustable, and thus the size of the ink plugging channel 2223 is adjustable.

[0063] Of course, an ink receiving tray (not shown) is also fixed below the plug assembly 22 and located within the plugging cavity 20. After the front plug 2211 and the rear plug 2221 plug the PCB 8 with ink, excess ink flows from the bottom of the plugging channel into the ink receiving tray for collection. To monitor the ink level in the ink receiving tray in real time, a laser sensor (not shown) can be fixed within the plugging cavity 20. The laser sensor is controlled by the electronic control box 9 of the fully automatic integrated vacuum plugging machine, which is mounted on the base frame 1 (e.g., Figure 3 As shown in the figure), the laser sensor monitors the ink level in the ink tray in real time to prevent the ink from overflowing due to excessive ink in the ink tray.

[0064] Reference Figure 1 A ventilation line 25 is also provided at the top of the plugging cavity 20. The ventilation line 25 communicates with the interior of the plugging cavity 20 and includes a ventilation valve 250. The ventilation line 25 is used to evacuate the interior of the plugging cavity 20. Specifically, after each plugging operation, the vacuum pump 6 is closed and the ventilation valve 250 on the ventilation line 25 is opened to evacuate the interior of the plugging cavity 20, thereby preventing ink atomization within the plugging cavity 20 from contaminating the workshop environment. Of course, the ventilation valve 250 on the ventilation line 25 is closed during vacuum plugging.

[0065] Reference Figure 1 In this embodiment, multiple plugging devices 2 can be provided according to actual working conditions. For example, in this embodiment, two plugging devices 2 are provided, that is, the fully automatic integrated vacuum plugging machine of the present invention has two plugging stations, which can improve the plugging efficiency and quality of the PCB board 8.

[0066] Reference Figure 1 、 Figure 14 and Figure 15 The ink scraping device 3 includes an ink scraping bin 30, a clamping mechanism B31, a lifting device B32, an ink scraping assembly 33 and an ink coating assembly 34.

[0067] Reference Figure 1 、 Figure 14 and Figure 15 The ink scraper chamber 30 is fixed to the base frame 1 and spaced apart from the plug hole cavity 20 along the horizontal direction of the base frame 1. The clamping mechanism B31 is located at the top of the ink scraper chamber 30. The rear side of the ink scraper chamber 30 has an opening 301, which is suitable for installing the automatic lifting door 202. The lifting device B32 is installed on the ink scraper chamber 30 and is used to drive the ink scraper assembly 33 to rise and fall within the ink scraper chamber 30, so that the ink scraper assembly 33 rises and falls in the vertical direction, scraping the ink on the PCB board 8 clamped and fixed by the clamping mechanism B31.

[0068] It should be noted that the structure of the clamping mechanism B31 is the same as that of the clamping mechanism A21; the structure of the lifting device B32 is the same as that of the lifting device A23, and will not be described in detail here. In addition, the structure of the ink scraping assembly 33 is the existing ink scraping assembly 33 structure and will not be described in detail here.

[0069] In addition, refer to Figure 14 or Figure 15 The bottom of the ink scraping chamber 30 is provided with a weighing device 35, and an ink collecting tray 36 is mounted on the weighing device 35. After the ink scraping assembly 33 has scraped the ink on the PCB board 8, the excess ink flows through the ink scraping channel of the ink scraping assembly 33 into the ink collecting tray 36 for collection. The ink scraping chamber 30 uses an ink collection and weighing method to monitor the ink level in the ink collecting tray 36 in real time. In addition, an ink collecting funnel 37 is provided between the ink collecting tray 36 and the ink scraping assembly 33. The ink collecting funnel 37 can be fixed to the inner wall of the ink scraping chamber 30. The ink collecting funnel 37 can collect ink directly in the ink collecting tray 36. The ink level in the ink collecting tray 36 is detected by weighing, preventing ink overflow and contamination of the equipment. At the same time, it improves the function of manual ink removal when the ink is full.

[0070] Reference Figure 14 and Figure 17 The ink coating assembly 34 is disposed on the ink scraping chamber 30 and includes a linear motion module (not shown), two connecting members 340, and two ink extrusion heads 341. The two connecting members 340 are disposed on the ink scraping chamber 30, and the two ink extrusion heads 341 are disposed on the two connecting members 340, respectively. The two ink extrusion heads 341 are located within the ink scraping chamber 30, on either side of the PCB board 8 clamped by the clamping mechanism B31. The ink extrusion heads 341 are connected to a vacuum ink squeezer 5 disposed outside the ink scraping chamber 30 via a pipeline. The vacuum ink squeezer 5 uses a vacuum method to supply ink to the ink extrusion heads 341. The ink extrusion heads 341 are used to apply ink to the PCB board 8 clamped by the clamping mechanism B31. The linear motion module is disposed at the top outside the ink scraping chamber 30 and is used to drive the two connecting members 340 to move laterally along the base frame 1. Each connector 340 is equipped with a telescopic mechanism 342. The telescopic end of each telescopic mechanism 342 extends longitudinally along the chassis 1 and is drivingly connected to an ink squeezer 341. The ink squeezer 341 is used to apply ink to the PCB 8 held in place by the clamping mechanism B31. As can be seen, the ink scraping device 3 of this embodiment achieves continuous, fully automated ink application and scraping, improving the production efficiency and quality of the PCB 8.

[0071] Reference Figures 18-23The transfer mechanism 4 includes a linear drive module 40 and a loading assembly 41. The linear drive module 40 is disposed on top of the base frame 1, outside the plug cavity 20 and the ink scraper chamber 30, along the transverse direction. The linear drive module 40 is used to drive the loading assembly 41 to move laterally. The loading assembly 41 is used to clamp and transport the PCB 8 to the clamping channel 215 of the clamping mechanism A21 or the clamping channel 215 of the clamping mechanism B31. The loading component 41 includes a clamping component 410 and a pushing component 411. The clamping component 410 is used to clamp the PCB board 8 to be plugged or scraped; the pushing component 411 is arranged along the longitudinal direction of the base frame 1, and the pushing component 411 is connected to the linear drive module 40 and the clamping component 410. The pushing component 411 is used to push the clamping component 410 into the plugging cavity 20 or the scraping bin 30. The pushing component 411 is also used to push the clamping component 410 out of the plugging cavity 20 or the scraping bin 30.

[0072] Reference Figures 18-23 The pusher assembly 411 includes a fixed base 4110, a movable base 4111, and a drive unit. The fixed base 4110 extends vertically, one end of which is drivingly connected to the linear drive module 40. Guide blocks are provided on opposite sides of the other end of the fixed base 4110. Slide rails are fixed to opposite sides of the movable base 4111. The slide rails extend longitudinally along the base frame 1 and slide relative to the guide blocks. The drive unit is provided on the movable base 4111 and drivingly connected to the clamping assembly 410. The drive unit is configured to drive the clamping assembly 410 to move longitudinally along the base frame 1. The driving unit includes a driving motor 4112 and a screw rod B4113. The driving motor 4112 is fixed on the movable seat 4111. The screw rod B4113 extends longitudinally along the base frame 1. The output shaft of the driving motor 4112 is drivingly connected to one end of the screw rod B4113, and is used to drive the screw rod B4113 to rotate. A nut B4114 is threadedly connected to the screw rod B4113, and the nut B4114 is fixed on the fixed seat 4110. The other end of the screw rod B4113 is connected to the clamping assembly 410 through the support seat, and the clamping assembly 410 is connected and fixed to the movable seat 4111. It can be seen from this that by driving the fixed seat 4110 to move laterally along the base frame 1 through the linear drive module 40, the pushing assembly 411 and the clamping assembly 410 can be driven to move laterally along the base frame 1; and since the nut B4114 threadedly connected on the screw rod B4113 is connected and fixed to the fixed seat 4110, and the screw rod B4113 is connected to the clamping assembly 410, and the clamping assembly 410 is connected and fixed to the movable seat 4111, when the drive motor 4112 drives the screw rod B4113 to rotate, the screw rod B4113 will drive the movable seat 4111 to move axially along the screw rod B4113. Of course, the drive motor 4112 also moves with the movable seat 4111, thereby driving the clamping assembly 410 to move axially along the screw rod B4113.

[0073] In addition, refer to Figure 22 A loading positioning plate 4115 is also fixed on the fixing seat 4110 , and the loading positioning plate 4115 is used to position the PCB board 8 when it is loaded onto the clamping assembly 410 .

[0074] Reference Figures 18-23 The clamping assembly 410 includes a connecting plate 4101, a driving mechanism 4102, and two feeding width adjustment plates 4103. The connecting plate 4101 extends laterally along the base frame 1 and is fixed to a movable seat 4111. The two feeding width adjustment plates 4103 are arranged at both ends of the connecting plate 4101 along the transverse direction of the base frame 1. The driving mechanism 4102 is disposed on the connecting plate 4101 and is used to drive the two feeding width adjustment plates 4103 to move toward or away from each other, thereby enabling the clamping assembly 410 to have a width adjustment function suitable for clamping and fixing PCB boards 8 of different sizes. In addition, an anti-fall plate 43 is also fixed to the movable seat 4111. The anti-fall plate 43 is used to prevent the PCB board 8 clamped by the clamping assembly 410 from falling.

[0075] The driving mechanism 4102 of this embodiment can be a screw driving mechanism; in other embodiments, the driving mechanism 4102 can also be a bidirectional cylinder, which is not limited here.

[0076] In addition to the above structure, the linear drive module 40 is also connected to a driving member 42. The member 42 is used to clamp the PCB board 8 in the ink scraper chamber 30 and transport the PCB board 8 to the next process. It should be noted that the structure of the member 42 is the same as that of the loading member 41 and will not be repeated here.

[0077] The working principle of the fully automatic integrated vacuum plugging machine of the present invention is:

[0078] During the plugging process, the PCB board 8 to be plugged is first clamped by the robot and automatically loaded onto the loading assembly 41. Then, the linear drive module 40 drives the loading assembly 41 to move horizontally along the base frame 1 to the door 201 corresponding to the plugging cavity 20. At this time, the door 201 is in an open state. Then, the loading assembly 41 extends the PCB board 8 clamped by itself into the plugging cavity 20 through the door 201. At this time, the lifting unit 2120 of the clamping mechanism A21 drives the lifting plate 212 to rise, avoiding the loading assembly 41 to transport the PCB board 8 along the longitudinal direction of the base frame 1 to the point where it abuts against the clamping plate 210 of the clamping mechanism A21. When the loading assembly 41 transports the PCB board 8 to the point where it abuts against the clamping plate 210 of the clamping mechanism A21, The lifting unit 2120 of the clamping mechanism A21 drives the lifting plate 212 of the clamping mechanism A21 to descend, and the telescopic units 213 of the clamping mechanism A21 drive the clamping claws 214 to move along the longitudinal direction of the base frame 1 toward the clamping plate 210 of the clamping mechanism A21, thereby clamping and fixing the PCB board 8 in the clamping channel 215 of the clamping mechanism A21; then, the door 201 of the plug hole cavity 20 is closed, so that the inner cavity of the plug hole cavity 20 is in a closed state, and the plug hole cavity 20 is vacuumed by the vacuum pumping device 6, and at the same time, the plug head assembly 22 is driven to move up and down by the lifting device A23, so that the ink sprayed from the plug head of the plug head assembly 22 plugs the PCB board 8 clamped and fixed on the clamping mechanism A21.

[0079] When the scraping process is in progress, the plugging process has been completed, the automatic lifting door 202 of the plugging cavity 20 is opened, and the loading component 41 extends into the plugging cavity 20 to clamp and fix the PCB board 8 clamped by the clamping mechanism A21. At this time, the lifting unit 2120 of the clamping mechanism A21 drives the lifting plate 212 to rise, and then the loading component 41 extends out of the plugging cavity 20 along the longitudinal direction of the base frame 1, and then the linear drive module 40 drives the loading component 41 to move horizontally along the base frame 1 to the opening 301 position of the scraping ink bin 30. At this time, the loading component 41 clamps the plugged PCB board 8 and transports it to the scraping ink bin 30 along the longitudinal direction of the base frame 1. At this time, the lifting unit 2120 of the clamping mechanism B31 drives the lifting plate 212 to rise, avoiding Let the loading component 41 transport the PCB board 8 along the longitudinal direction of the base frame 1 to the point where it abuts against the clamping plate 210 of the clamping mechanism B31; after the loading component 41 transports the PCB board 8 to the point where it abuts against the clamping plate 210 of the clamping mechanism B31, the lifting unit 2120 of the clamping mechanism B31 drives the lifting plate 212 of the clamping mechanism B31 to descend, and the telescopic units 213 of the clamping mechanism B31 drive the clamping claws 214 to move along the longitudinal direction of the base frame 1 toward the clamping plate 210 of the clamping mechanism B31, thereby clamping and fixing the PCB board 8 in the clamping channel 215 of the clamping mechanism B31; at this time, the ink scraping component 33 is driven up and down by the lifting device B32 to scrape ink from the PCB board 8 clamped and fixed on the clamping mechanism B31.

[0080] In summary, 1. The fully automatic integrated vacuum plugging machine of the present invention can automatically complete the plugging and ink scraping processes of the PCB board 8. At the same time, the PCB board 8 can be moved to the clamping mechanism of the plugging device 2 or the clamping mechanism of the ink scraping device 3 through the transfer mechanism 4, and the loading action of the plugging process or the ink scraping process of the PCB board 8 is automatically completed, thereby ensuring the efficiency, quality and yield of the plugging process and the ink scraping process of the PCB board 8.

[0081] 2. The clamping mechanism A21 and the clamping mechanism B31 involved in the present invention have the lifting and clamping functions, so that the clamping mechanism A21 or the clamping mechanism B31 is used in conjunction with the clamping assembly 410, which not only optimizes the space utilization in the plugging cavity 20 or the ink scraping chamber 30, but also realizes efficient, flexible and high-precision plugging or ink scraping operations.
