Description

Technical Field

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

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

[0003] The existing plug hole machines for PCB boards can usually only perform the plug hole process for PCB boards and cannot perform the scraping ink process, and the scraping ink process for PCB boards needs to be completed by a scraping ink machine. That is, when performing the plug hole process for a PCB board, the PCB board must be manually placed into the plug hole machine, and the PCB board is clamped by the clamping mechanism inside the plug hole machine for the plug hole process. After the plug hole process, the PCB board is manually taken out of the plug hole machine and manually placed into the scraping ink machine, and the PCB board is clamped by the clamping mechanism inside the scraping ink machine for the scraping ink process.

[0004] In summary, in the prior art, the plug hole and scraping ink processes of PCB boards cannot be completed on a plug hole machine centrally. At the same time, when performing the plug hole and scraping ink processes, the PCB board needs to be manually placed in the clamping mechanism of the plug hole machine or the scraping ink machine. During the process of manually transferring the PCB board, due to the fatigue of the workers, it may not be possible to ensure the efficiency, quality, and yield of the plug hole process and the scraping ink process of the PCB board. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, one of the purposes of the present invention is to provide a fully automatic integrated vacuum plug hole machine, which aims to solve the technical problems that the plug hole and scraping ink processes of PCB boards cannot be completed on a plug hole machine centrally, and at the same time, due to the fatigue of workers when manually transferring the PCB board from the plug hole process to the scraping ink process, it is impossible to ensure the efficiency, quality, and yield of the plug hole process and the scraping ink process of the PCB board.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A fully automatic integrated vacuum plug hole machine, comprising: A chassis; The plugging device includes a plugging cavity, a clamping mechanism A, a lifting device A and a plug head assembly. The plugging cavity is arranged on the chassis and is communicated with a vacuum pumping device arranged outside the plugging cavity. The clamping mechanism A is arranged in the plugging cavity. The clamping mechanism A includes a clamping plate, a lifting plate and a plurality of telescopic units. The clamping plate is fixed in the plugging cavity. Lifting units are arranged at both ends of the clamping plate. The lifting ends of the lifting units are connected to the lifting plate. A plurality of telescopic units are all arranged on the lifting plate. The telescopic ends of the telescopic units are connected with clamping jaws. A clamping channel is formed between the plurality of clamping jaws and the clamping plate. The lifting device A is arranged on the plugging cavity and is used to drive the plug head assembly to lift in the plugging cavity. A plug head is arranged on the plug head assembly. The plug head is communicated with an ink negative pressure pipeline outside the plugging cavity and is used to fill ink into the holes of the PCB board clamped by the clamping mechanism A; The ink scraping device includes an ink scraping bin, a clamping mechanism B, a lifting device B and an ink scraping assembly. The ink scraping bin is fixed on the chassis. The ink scraping bin is arranged at an interval from the plugging cavity along the transverse direction of the chassis. The clamping mechanism B is arranged in the ink scraping bin. 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 bin and is used to drive the ink scraping assembly to lift in the ink scraping bin; The transfer mechanism includes a linear driving module and a loading component. The linear driving module is arranged at the top outside the plugging cavity and outside the ink scraping bin along the transverse direction of the chassis. The linear driving module is used to drive the loading component to move horizontally. The loading component is used to clamp and convey the PCB board to the clamping channel.

[0007] Further, the loading component includes a clamping component, and the clamping component is used to clamp the PCB board to be plugged or ink scraped.

[0008] Further, the loading component further includes a pushing component. The pushing component is arranged along the longitudinal direction of the chassis. The pushing component is connected to the linear driving module and the clamping component. The pushing component is used to push the clamping component into the plugging cavity or the ink scraping bin, and the pushing component is further used to push the clamping component out of the plugging cavity or the ink scraping bin.

[0009] Further, the pushing component includes a fixed seat, a moving seat and a driving unit. The fixed seat extends in the vertical direction. One end of the fixed seat is drivingly connected to the linear driving module. Guide blocks are arranged on opposite sides of the other end of the fixed seat. Slide rails are fixed on opposite sides of the moving seat. The slide rails extend along the longitudinal direction of the chassis. The slide rails slide relative to the guide blocks. The driving unit is arranged on the moving seat and is drivingly connected to the clamping component. The driving unit is used to drive the clamping component to move along the longitudinal direction of the chassis.

[0010] Further, a falling prevention plate member is arranged on the moving seat to prevent the PCB board clamped by the clamping component from falling.

[0011] Further, the clamping assembly includes a connecting plate, a driving mechanism, and two loading width-adjusting plates. The connecting plate extends along the transverse direction of the chassis and is fixed on the moving seat. The two loading width-adjusting plates are arranged at both ends of the connecting plate along the transverse direction of the chassis. The driving mechanism is arranged on the connecting plate and is used to drive the two loading width-adjusting plates to move towards or away from each other.

[0012] Further, an air exchange pipeline is arranged at the top of the plug hole cavity. The air exchange pipeline is communicated with the inside of the plug hole cavity. An air exchange valve is provided on the air exchange pipeline. The air exchange pipeline is used to evacuate the inner cavity of the plug hole cavity.

The ink coating assembly includes two connecting pieces and two ink squeezing heads. The two connecting pieces are arranged on the ink scraping bin. The two ink squeezing heads are respectively arranged on the two connecting pieces. The two ink squeezing heads are located inside the ink scraping bin. The two ink squeezing heads are located on both sides of the PCB board clamped by the clamping mechanism B. The ink squeezing heads are communicated with a vacuum ink squeezing machine arranged outside the ink scraping bin through pipelines. The vacuum ink squeezing machine transports ink to the ink squeezing heads in a vacuum manner. The ink squeezing heads are used to coat ink on the PCB board clamped by the clamping mechanism B.

[0014] Further, the ink coating assembly further includes a linear movement module. The linear movement module is arranged at the top outside the ink scraping bin and is used to drive the two connecting pieces to move along the transverse direction of the chassis.

[0015] Further, a telescopic mechanism is arranged on each connecting piece. The telescopic end of each telescopic mechanism extends along the longitudinal direction of the chassis. The telescopic end of each telescopic mechanism is drivingly connected to each ink squeezing head.

[0016] Compared with the prior art, the advantages of the present invention are as follows: When the full-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 component by the manipulator, and then the loading component is driven by the linear driving module to move horizontally along the chassis to the position corresponding to the plugging cavity. Then, the loading component extends the clamped PCB board into the plugging cavity. At this time, the lifting unit of the clamping mechanism A drives the lifting plate to rise, avoiding the loading component to convey the PCB board longitudinally along the chassis until it abuts against the clamping plate of the clamping mechanism A; after the loading component conveys the PCB board until 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 each telescopic unit of the clamping mechanism A drives each claw of the clamping mechanism A to move longitudinally along the chassis towards the clamping plate of the clamping mechanism A, so as to clamp and fix 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 evacuated by the vacuum pumping device. At the same time, the plug head assembly is driven to move up and down by the lifting device A, so that the ink ejected from the plug head of the plug head assembly plugs the PCB board clamped and fixed by the clamping mechanism A.

[0017] After the plugging operation of the PCB board is completed, the plugging cavity is opened, and the loading component 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 component extends out of the plugging cavity longitudinally along the chassis. Then, the loading component is driven by the linear driving module to move horizontally along the chassis to the position of the ink scraping bin. At this time, the loading component conveys the PCB board after plugging itself longitudinally along the chassis into the ink scraping bin. At this time, the lifting unit of the clamping mechanism B drives the lifting plate to rise, avoiding the loading component to convey the PCB board longitudinally along the chassis until it abuts against the clamping plate of the clamping mechanism B; after the loading component conveys the PCB board until 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 each telescopic unit of the clamping mechanism B drives each claw of the clamping mechanism B to move longitudinally along the chassis towards the clamping plate of the clamping mechanism B, so as to clamp and fix the PCB board in the clamping channel of the clamping mechanism B; at this time, the ink scraping component is driven to move up and down by the lifting device B to scrape the ink on the PCB board clamped and fixed on the clamping mechanism B.

[0018] In summary, the full-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, through the transfer mechanism, the PCB board can be moved to the clamping mechanism of the plugging device or the clamping mechanism of the ink scraping device for clamping, 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.

[0024] Please refer to Figures 1 - 23 , the present invention provides a fully automatic integrated vacuum plugging machine, which includes a chassis 1, a plugging device 2, an ink scraping device 3, and a transfer mechanism 4.

[0025] Refer to 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 chassis 1, and the inner cavity of the plugging cavity 20 is communicated with a vacuum pumping device 6 arranged outside the plugging cavity 20. A doorway 201 is opened at the rear side of the plugging cavity 20, and an automatic lifting door 202 is installed at the doorway 201. The automatic lifting door 202 is used to close the doorway 201. Of course, the vacuum pumping device 6 can extract vacuum from the inner cavity of the plugging cavity 20. When it is necessary to extract vacuum from the inner cavity of the plugging cavity 20, the doorway 201 of the plugging cavity 20 is in a closed state through the automatic lifting door 202.

[0026] The automatic lifting door 202 selects an existing automatic lifting door structure and will not be elaborated here.

[0027] Refer to Figure 4 and Figures 11 - 13, the clamping mechanism A21 is arranged in the plug hole cavity 20. The clamping mechanism A21 includes a clamping plate 210, a lifting plate 212 and a plurality of telescopic units 213. The clamping plate 210 is fixed at the top inside the plug hole cavity 20. Lifting units 2120 are fixed at 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. A plurality of telescopic units 213 are all arranged on the lifting plate 212. The telescopic ends of the telescopic units 213 are connected with clamping jaws 214. A clamping channel 215 is formed between the plurality of clamping jaws 214 and the clamping plate 210. Of course, the clamping channel 215 is mainly used for clamping and fixing the PCB board 8 to be plugged.

[0028] In this embodiment, the telescopic unit 213 is selected as a telescopic cylinder; the lifting unit 2120 is selected as a lifting cylinder; in other embodiments, the telescopic unit 213 or the lifting unit 2120 can also be an electric push rod.

[0029] Refer to Figure 4 and Figure 6 , the lifting device A23 is arranged on the plug hole cavity 20. The lifting device A23 is used to drive the plug head assembly 22 to lift in the plug hole cavity 20. Specifically, the lifting device A23 includes a lifting power assembly 230 and a lead screw mechanism 231. The lifting power assembly 230 is arranged on the top surface outside the plug hole cavity 20. The lead screw A24 of the lead screw mechanism 231 is drivingly connected to the lifting power assembly 230, and the lead screw A24 of the lead screw mechanism 231 is arranged inside the plug hole cavity 20. Of course, the lead screw mechanisms 231 are arranged at both ends of the mounting seat 220. The two ends of the mounting seat 220 are respectively drivingly connected to the lead screws A24 of the two lead screw mechanisms 231. In this way, by driving the lead screw A24 of each lead screw mechanism 231 to rotate through the lifting power assembly 230, the mounting seat 220 can be driven to lift in the vertical direction, so as to achieve the purpose of driving the plug head assembly 22 to lift up and down in the plug hole cavity 20 by the lifting device A23. Of course, in other embodiments, the lifting device A23 can also be an electric push rod or a linear module, which is not limited here.

[0030] Refer to Figure 4 and Figures 6 - 10 , the plug head assembly 22 is arranged at the bottom inside the plug hole cavity 20; a plug head is arranged on the plug head assembly 22. Among them, the plug heads are respectively a front plug head 2211 and a rear plug head 2221. The front plug head 2211 and the rear plug head 2221 are communicated with an ink negative pressure pipeline outside the plug hole cavity 20. The front plug head 2211 and the rear plug head 2221 are used to fill ink into the holes of the PCB board clamped by the clamping mechanism A. Among them, the ink negative pressure pipeline is communicated with an ink supply device 7 arranged outside the plug hole cavity 20. The ink supply device 7 supplies ink to the plug head. The ink supply device 7 selects an existing ink supply structure, and its specific structure is not described in detail here.

[0031] Refer to Figures 6 - 10, the plug component 22 of this embodiment includes a mounting base 220, a front plug component 221, and a rear plug component 222. The left and right ends of the mounting base 220 are respectively connected to the lifting device A23, and the mounting base 220 can be lifted and lowered in the vertical direction through the lifting device A23.

[0032] Referring to 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 base 220 along the longitudinal direction of the low frame. The plug of the front plug component 221 is mounted and 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 mounted and fixed on the side of the rear mounting plate 2220 facing the front mounting plate 2210. A plug ink channel 2223 is formed between the front plug 2211 and the rear plug 2221. The plug ink channel 2223 penetrates through the opposite surfaces of the mounting base 220. The plug ink channel 2223 is located directly below the clamping channel 215 of the clamping mechanism A21. The inner diameter of the plug ink channel 2223 is larger than the thickness of the PCB board 8, so that the plug ink channel 2223 can accommodate the PCB board 8. When performing the plug hole process on the PCB board 8, the automatic lifting door 202 closes the door 201 of the plug hole cavity 20, the inner cavity of the plug hole cavity 20 is evacuated, 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, and at the same time drives the plug component 22 to move up and down through the lifting device A23, so that the front plug 2211 and the rear plug 2221 fill the ink into the holes on the PCB board 8, thereby completing the plug hole process of the PCB board 8.

[0033] Referring to Figure 4 and Figures 6 - 10 , the front plug component 221 further includes a telescopic cylinder A2212 for driving the front mounting plate 2210 to move longitudinally along the chassis 1 towards or away from the rear mounting plate 2220. A plurality of telescopic cylinders A2212 are provided, and all the plurality of telescopic cylinders A2212 are fixed in the plug hole cavity 20. Similarly, the rear plug component 222 further includes a telescopic cylinder B2222 for driving the rear mounting plate 2220 to move longitudinally along the chassis 1 towards or away from the front mounting plate 2210. A plurality of telescopic cylinders B2222 are provided, and all the plurality of telescopic cylinders B2222 are fixed in the plug hole cavity 20. It can be seen from this that the distance between the front mounting plate 2210 and the rear mounting plate 2220 is adjustable, that is, the size of the plug ink channel 2223 is adjustable.

[0034] Of course, a ink receiving tray (not shown) located in the plug hole cavity 20 is also fixed below the plug head assembly 22. After the current plug head 2211 and the rear plug head 2221 perform ink plugging on the PCB board 8, the excess ink enters the ink receiving tray from below the ink plugging channel for collection. In order to monitor the ink volume in the ink receiving tray in real time, a laser sensor (not shown) can be fixed in the plug hole cavity 20. The laser sensor is controlled by the electric control box 9 of the fully automatic integrated vacuum plug hole machine. The electric control box 9 is installed on the chassis 1 (as Figure 3 shown), and the ink volume in the ink receiving tray is monitored in real time by the laser sensor to avoid overflow due to excessive ink volume in the ink receiving tray.

[0035] Refer to Figure 1 . A gas exchange pipeline 25 is also provided at the top of the plug hole cavity 20. The gas exchange pipeline 25 is communicated with the inside of the plug hole cavity 20. A gas exchange valve 250 is provided on the gas exchange pipeline 25. The gas exchange pipeline 25 is used to evacuate the inner cavity of the plug hole cavity 20. Specifically, it can be understood that after each plug hole is completed, the vacuum pumping device 6 is turned off, and the gas exchange valve 250 on the gas exchange pipeline 25 is opened to evacuate the inner cavity of the plug hole cavity 20 to avoid ink atomization in the plug hole cavity 20 from polluting the working environment of the workshop. Of course, when performing vacuum plug hole, the gas exchange valve 250 on the gas exchange pipeline 25 is closed.

[0036] Refer to Figure 1 . Multiple plug hole devices 2 of this embodiment can be set according to the actual working conditions. Exemplarily, two plug hole devices 2 are provided in this embodiment, that is, the fully automatic integrated vacuum plug hole machine of the present invention has two plug hole stations, so that the plug hole efficiency and quality of the PCB board 8 can be improved.

[0037] Refer to 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.

[0038] Refer to Figure 1 , Figure 14 and Figure 15 . The ink scraping bin 30 is fixed on the chassis 1. The ink scraping bin 30 is arranged at a distance from the plug hole cavity 20 along the transverse direction of the chassis 1. The clamping mechanism B31 is arranged at the top inside the ink scraping bin 30. An opening 301 is provided on the rear side of the ink scraping bin 30, and an automatic lifting door 202 can be installed at the opening 301. The lifting device B32 is arranged on the ink scraping bin 30 and is used to drive the ink scraping assembly 33 to lift in the ink scraping bin 30, so that the ink scraping assembly 33 moves up and down in the vertical direction to scrape the ink on the PCB board 8 clamped and fixed by the clamping mechanism B31.

[0039] 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 elaborated here. In addition, the structure of the ink scraping component 33 is the existing structure of the ink scraping component 33, and will not be described in detail here.

[0040] In addition, referring to Figure 14 or Figure 15 , a weighing device 35 is provided at the bottom inside the ink scraping bin 30, and an ink collecting tray 36 is provided on the weighing device 35. After the ink on the PCB board 8 is leveled by the ink scraping component 33, the excess ink enters the ink collecting tray 36 through the ink scraping channel of the ink scraping component 33 for collection. The ink receiving and weighing method is adopted inside the ink scraping bin 30 to monitor the ink volume in the ink collecting tray 36 in real time. In addition, an ink receiving funnel 37 is provided between the ink collecting tray 36 and the ink scraping component 33. The ink receiving funnel 37 can be fixed on the inner wall of the ink scraping bin 30. The ink receiving funnel 37 can directly collect the ink in the ink collecting tray 36, and the ink volume in the ink collecting tray 36 is detected by weighing, so as to avoid ink overflow and pollute the equipment. At the same time, it has the function of prompting manual ink collection when the ink is full.

[0041] Referring to Figure 14 and Figure 17 , the ink coating component 34 is arranged on the ink scraping bin 30. The ink coating component 34 includes a linear movement module (not shown), two connecting pieces 340 and two ink extrusion heads 341. Among them, the two connecting pieces 340 are arranged on the ink scraping bin 30, and the two ink extrusion heads 341 are respectively arranged on the two connecting pieces 340. Of course, the two ink extrusion heads 341 are located inside the ink scraping bin 30, and the two ink extrusion heads 341 are located on both sides of the PCB board 8 clamped by the clamping mechanism B31. The ink extrusion heads 341 are connected to a vacuum ink extrusion machine 5 arranged outside the ink scraping bin 30 through pipelines. The vacuum ink extrusion machine 5 uses a vacuum method to transport ink to the ink extrusion heads 341. The ink extrusion heads 341 are used to coat ink on the PCB board 8 clamped by the clamping mechanism B31. The linear movement module is arranged on the top outside the ink scraping bin 30. The linear movement module is used to drive the two connecting pieces 340 to move horizontally along the chassis 1. A telescopic mechanism 342 is arranged on each connecting piece 340. The telescopic end of each telescopic mechanism 342 extends longitudinally along the chassis 1. The telescopic end of each telescopic mechanism 342 is drivingly connected to each ink extrusion head 341. The ink extrusion heads 341 can coat ink on the PCB board 8 clamped and fixed by the clamping mechanism B31. It can be seen that the ink scraping device 3 in this embodiment realizes continuous integrated full automation of ink coating and ink scraping, improving the production efficiency and quality of the PCB board 8.

[0042] Referring to Figures 18 - 23, the transfer mechanism 4 includes a linear drive module 40 and a loading component 41. The linear drive module 40 is arranged transversely along the base frame 1 at the top outside the plug hole cavity 20 and outside the ink scraping bin 30. The linear drive module 40 is used to drive the loading component 41 to move transversely, and the loading component 41 is used to clamp and convey the PCB board 8 to the clamping channel 215 of the clamping mechanism A21 or the clamping channel 215 of the clamping mechanism B31.

The pushing component 411 is used to push the clamping component 410 into the plug hole cavity 20 or the ink scraping bin 30, and the pushing component 411 is also used to push the clamping component 410 out of the plug hole cavity 20 or the ink scraping bin 30.

[0043] Refer to Figures 18 - 23 , the pushing component 411 includes a fixed seat 4110, a moving seat 4111 and a driving unit. Among them, the fixed seat 4110 extends in the vertical direction. One end of the fixed seat 4110 is drivingly connected to the linear drive module 40, and guiding blocks are arranged on the opposite sides of the other end of the fixed seat 4110. Slide rails are fixed on the opposite sides of the moving seat 4111. The slide rails extend longitudinally along the base frame 1, and the slide rails slide relative to the guiding blocks. The driving unit is arranged on the moving seat 4111 and is drivingly connected to the clamping component 410. The driving unit is used to drive the clamping component 410 to move longitudinally along the base frame 1. The driving unit includes a driving motor 4112 and a lead screw B4113. The driving motor 4112 is fixed on the moving seat 4111. The lead screw B4113 extends longitudinally along the base frame 1. The output shaft of the driving motor 4112 is drivingly connected to one end of the lead screw B4113 for driving the lead screw B4113 to rotate. A nut B4114 is threadedly connected to the lead screw B4113, and the nut B4114 is fixed on the fixed seat 4110. The other end of the lead screw B4113 is connected to the clamping component 410 through a support seat, and the clamping component 410 is fixedly connected to the moving seat 4111. It can be seen from this that by driving the fixed seat 4110 to move transversely along the base frame 1 through the linear drive module 40, the pushing component 411 and the clamping component 410 can be driven to move transversely along the base frame 1; and because the nut B4114 threadedly connected to the lead screw B4113 is fixedly connected to the fixed seat 4110, and the lead screw B4113 is connected to the clamping component 410, and the clamping component 410 is fixedly connected to the moving seat 4111, so when the driving motor 4112 drives the lead screw B4113 to rotate, the lead screw B4113 will drive the moving seat 4111 to move axially along the lead screw B4113. Of course, the driving motor 4112 also moves with the moving seat 4111, thereby driving the clamping component 410 to move axially along the lead screw B4113.

[0044] In addition, referring to Figure 22 , a loading positioning plate 4115 is further fixed on the fixed seat 4110. The loading positioning plate 4115 is used for positioning the PCB board 8 when it is loaded onto the clamping assembly 410.

[0045] Referring to Figures 18 - 23 , the clamping assembly 410 includes a connecting plate 4101, a driving mechanism 4102 and two loading width-adjusting plates 4103. The connecting plate 4101 extends along the transverse direction of the base frame 1. The connecting plate 4101 is fixed on the moving seat 4111. The two loading width-adjusting 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 arranged on the connecting plate 4101. The driving mechanism 4102 is used to drive the two loading width-adjusting plates 4103 to move towards or away from each other, so that the clamping assembly 410 has a width-adjusting function to be suitable for clamping and fixing PCB boards 8 of different sizes. In addition, an anti-falling plate member 43 is further fixed on the moving seat 4111. The anti-falling plate member 43 is used to prevent the PCB board 8 clamped by the clamping assembly 410 from falling.

[0046] The driving mechanism 4102 of this embodiment can select a screw driving mechanism; in other embodiments, the driving mechanism 4102 can also be a double-acting cylinder, which is not limited here.

[0047] On the basis of the above structure, the linear driving module 40 is also drivingly connected with a blanking assembly 42. The blanking assembly 42 is used to clamp the PCB board 8 in the ink scraping bin 30 and convey the PCB board 8 to the next process. It should be noted that the structure of the blanking assembly 42 is the same as that of the loading assembly 41, and will not be described in detail here.

[0048] The working principle of the full-automatic integrated vacuum plugging machine of the present invention: When performing the plugging process, first, a manipulator is used to clamp the PCB board 8 to be plugged and automatically feed it onto the feeding component 41. Then, the linear driving module 40 drives the feeding component 41 to move horizontally along the chassis 1 to the door 201 corresponding to the plugging cavity 20. At this time, the door 201 is in an open state. Next, the feeding component 41 extends the clamped PCB board 8 from the door 201 into the plugging cavity 20. At this time, the lifting unit 2120 of the clamping mechanism A21 drives the lifting plate 212 to rise, avoiding the feeding component 41 from longitudinally transporting the PCB board 8 along the chassis 1 until it abuts against the clamping plate 210 of the clamping mechanism A21. After the feeding component 41 transports the PCB board 8 until 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 each telescopic unit 213 of the clamping mechanism A21 drives each clamping jaw 214 to move longitudinally along the chassis 1 towards 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 plugging cavity 20 is closed, making the inner cavity of the plugging cavity 20 in a closed state, and the vacuum in the plugging cavity 20 is extracted by the vacuum extraction device 6. 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 ejected from the plug head of the plug head assembly 22 plugs the holes of the PCB board 8 clamped and fixed on the clamping mechanism A21.

[0049] When performing the ink scraping process, the plugging process has been completed. The automatic lifting door 202 of the plugging cavity 20 is opened, and the feeding 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. Then, the feeding component 41 extends out of the plugging cavity 20 longitudinally along the chassis 1, and then the linear driving module 40 drives the feeding component 41 to move horizontally along the chassis 1 to the position of the opening 301 of the ink scraping chamber 30. At this time, the feeding component 41 longitudinally transports the PCB board 8 after plugging the holes by itself into the ink scraping chamber 30 along the chassis 1. At this time, the lifting unit 2120 of the clamping mechanism B31 drives the lifting plate 212 to rise, avoiding the feeding component 41 from longitudinally transporting the PCB board 8 along the chassis 1 until it abuts against the clamping plate 210 of the clamping mechanism B31. After the feeding component 41 transports the PCB board 8 until 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 each telescopic unit 213 of the clamping mechanism B31 drives each clamping jaw 214 to move longitudinally along the chassis 1 towards 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 to move up and down by the lifting device B32 to scrape the ink on the PCB board 8 clamped and fixed on the clamping mechanism B31.

[0050] 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, through the transfer mechanism 4, 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, and the feeding action of the plugging process or the ink scraping process of the PCB board 8 can be automatically completed, thereby ensuring the efficiency, quality and yield of the plugging process and the ink scraping process of the PCB board 8.

[0051] 2. The clamping mechanism A21 and the clamping mechanism B31 involved in the present invention have the functions of lifting and clamping, so that the clamping mechanism A21 or the clamping mechanism B31 is used in cooperation 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.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
