Specifically, along the height direction of the circuit board carbon oil filling hole device 100, The first air outlet 3211 is arranged on the upper end wall of the fixing plate 321, the first air inlet 3221 and the second air inlet 3222 are both arranged on the lower end wall of the reversing plate 322, the first air inlet 3221 is connected to the air outlet end of the fan 31, the second air inlet 3222 is connected to the air inlet end of the fan 31, the first air inlet 3221 and the second air inlet 3222 are both suitable for being arranged opposite to and in communication with the first air outlet 3211, and the height direction of the circuit board carbon oil filling hole device 100 can refer to Figure 1 The up and down directions in .

[0032] In some specific embodiments, the first driving member 323 and the fixed plate 321 can be fixedly connected to the mounting frame 1. In other specific embodiments, an iron pipeline is connected between the first air outlet 3211 and the air disk 2, and the iron pipeline between the fixed plate 321 and the first air outlet 3211 and the air disk 2 is fixedly connected, that is, the iron pipeline between the fixed plate 321 and the first air outlet 3211 and the air disk 2 can maintain a relative position unchanged, and the first driving member 323 is installed on the outer peripheral wall of the fixed plate 321.

[0033] Furthermore, a seal is provided between the reversing plate 322 and the fixing plate 321 .

[0034] In addition, the first driving member 323 is connected and cooperated with the reversing plate 322. The first driving member 323 is used to drive the reversing plate 322 to move between the first position and the second position relative to the first air outlet 3211. Specifically, along the first direction of the circuit board carbon oil hole filling device 100, the first driving member 323 drives the reversing plate 322 to move left or right relative to the first air outlet 3211, so that the reversing plate 322 moves between the first position and the second position. In the first position, the second air inlet 3222 and the first air outlet 3211 are opposite and connected. In the second position, the first air inlet 3221 and the first air outlet 3211 are opposite and connected. The first direction of the circuit board carbon oil hole filling device 100 can refer to Figure 1 The left and right direction in .

[0035] Specifically, when the sheet material is placed on the top wall of the air disk 2 and the upper end surface of the sheet material is coated with carbon oil, the first driving member 323 drives the reversing plate 322 to move to the first position so that the second air inlet 3222 and the first air outlet 3211 are opposite and connected, and then the fan 31 starts to work, and the air inlet end of the fan 31 sucks the air disk 2 through the second air inlet 3222 and the first air outlet 3211 to form a negative pressure in the ventilation space 21. Under the action of air pressure, the carbon oil on the upper end surface of the sheet material penetrates through the prefabricated holes on the sheet material to the lower end surface of the sheet material, thereby completing the carbon oil hole filling process of the sheet material.

In addition, when the unprocessed sheet is placed on the gas disk 2, the unequal negative pressure in each area of ​​the gas disk 2 can be avoided as much as possible. When the fan 31 sucks the unprocessed sheet, the suction force on each area of ​​the lower end surface of the sheet is as consistent as possible, so that the carbon oil on the upper end surface of the sheet can penetrate into the lower end surface of the sheet as evenly as possible.

[0037] In some specific embodiments, the first driving member 323 may be a cylinder, but the present application is not limited thereto, and the first driving member 323 may also be a hydraulic cylinder or the like.

[0038] Thus, the reversing plate 322 is driven to move between the first position and the second position by the first driving member 323. When the reversing plate 322 is located at the first position, the fan 31 sucks the lower end surface of the sheet through the air disk 2, so that the carbon oil penetrates from the upper end surface of the sheet to the lower end surface of the sheet. When the reversing plate 322 is located at the second position, the fan 31 blows air to the air disk 2 to release the negative pressure state in the air disk 2, which can avoid the unequal negative pressure in each area of ​​the air disk 2 as much as possible. Compared with the prior art, when the sheet carbon oil filling hole processing is completed and the unprocessed sheet is placed on the air disk 2, the suction force of each area of ​​the lower end surface of the sheet can be avoided as much as possible, so that the carbon oil on the upper end surface of the sheet can penetrate into the lower end surface of the sheet as evenly as possible, thereby improving the product quality of the sheet.

In the first position, the first air inlet 3221 and the second air outlet 3212 are arranged opposite to and connected with each other.

[0040] Specifically, when the sheet material is placed on the upper end wall of the air disk 2, the first driving member 323 drives the reversing plate 322 to move to the first position, the first air inlet 3221 and the second air outlet 3212 are arranged opposite to and connected to each other, and the air inlet end of the fan 31 sucks the lower end surface of the sheet material through the second air inlet 3222, the first air outlet 3211 and the air disk 2, and the air outlet end of the fan 31 blows the gas to the silencer 33 through the first air inlet 3221 and the second air outlet 3212. The silencer 33 is used to eliminate the noise generated by the gas, so as to minimize the noise generated by the circuit board carbon oil filling equipment 100 during operation, thereby improving the working comfort of the workers.

[0041] It should be noted that when the reversing plate 322 is located at the second position, the air inlet end of the fan 31 is not connected to the silencer 33 .

[0044] By setting a flow regulating member 34 in the first connecting pipeline 36, the flow regulating member 34 can adjust the flow of gas in the first pipeline, so as to control the suction force of the fan 31 on the sheet material, and can prevent the sheet material from being damaged due to excessive suction force, thereby improving the working reliability of the circuit board carbon oil filling device 100.

Along the height direction of the circuit board carbon oil filling device 100, the air inlet end of the fan 31 sucks the lower end surface of the sheet through the air disk 2.

[0049] After completing the carbon oil hole filling process of the sheet material, the fan 31 does not stop working, the air shut-off valve 35 connects the air inlet end of the fan 31 and the third air inlet 351, and cuts off the air disk 2 and the air inlet end of the fan 31, and then the first driving member 323 drives the reversing plate 322 to move from the first position to the second position, and the air inlet end of the fan 31 sucks the gas in the external environment through the third air inlet 351, and the air outlet end of the fan 31 blows gas to the air disk 2 to relieve the negative pressure state in the air disk 2.

[0050] After the worker takes out the sheet from the air disk 2, the fan 31 does not stop working, and the first driving member 323 drives the reversing plate 322 to move from the second position to the first position, and then the air shut-off valve 35 connects the air inlet end of the fan 31 and the air disk 2, and cuts off the third air inlet 351 and the air inlet end of the fan 31, thereby achieving the technical effect of the cyclic operation of the circuit board carbon oil filling equipment 100.

[0051] When the fan 31 continues to work to improve the processing efficiency of the circuit board carbon oil filling device 100, and the first driving member 323 drives the reversing plate 322 to move between the first position and the second position, the air shut-off valve 35 connects the air inlet end of the fan 31 and the third air inlet 351, and cuts off the air disk 2 and the air inlet end of the fan 31, thereby preventing the fan 31 from sucking gas from the external environment through the second air inlet 3222, avoiding the second air inlet 3222 from adsorbing the end wall of the fixed plate 321 opposite to the reversing plate 322, preventing the first driving member 323 from being unable to drive the reversing plate 322 to move between the first position and the second position, thereby improving the working reliability of the circuit board carbon oil filling device 100.

[0052] Reference Figure 5 and Figure 8 In some embodiments of the present application, the blowing and suction assembly 3 may further include a second connecting pipeline 37, there are multiple ventilation holes 22, and the multiple ventilation holes 22 are spaced apart along the radial direction of the circuit board carbon oil hole filling device 100, and a partition plate 23 is arranged in the air disk 2. Specifically, along the height direction of the circuit board carbon oil hole filling device 100, the partition plate 23 is vertically arranged in the air disk 2, and the partition plate 23 divides the ventilation space 21 into multiple sub-ventilation spaces 211 spaced apart along the radial direction of the circuit board carbon oil hole filling device 100.

[0053] It should be noted that the number of the sub-ventilation spaces 211 is related to the shape of the partition plate 23 .

[0054] In some specific embodiments, when the shape of the partition plate 23 is constructed as a flat plate, along the first direction of the circuit board carbon oil filling device 100, the partition plate 23 divides the ventilation space 21 into two sub-ventilation spaces 211, one of the two sub-ventilation spaces 211 is located on the left side of the partition plate 23, and the other of the two sub-ventilation spaces 211 is located on the right side of the partition plate 23.

[0055] In other specific embodiments, when the partition plate 23 is configured in a cross shape, the partition plate 23 divides the ventilation space 21 into four sub-ventilation spaces 211 , and the four ventilation spaces 21 are spaced apart in the radial direction of the circuit board carbon oil filling device 100 .

[0056] Furthermore, one end of the second connecting pipeline 37 is connected to the first air outlet 3211, and the other end of the second connecting pipeline 37 is provided with a plurality of third air outlets 371 spaced apart along the radial direction of the circuit board carbon oil filling device 100. The plurality of third air outlets 371 correspond one-to-one to the plurality of sub-ventilation spaces 211 and are connected. The fan 31 draws gas from the plurality of sub-ventilation spaces 211 through the plurality of third air outlets 371, and blows gas into the plurality of sub-ventilation spaces 211.

[0057] By setting a partition plate 23 in the air disk 2, the partition plate 23 divides the ventilation space 21 into multiple sub-ventilation spaces 211, and the multiple sub-ventilation spaces 211 correspond to the multiple areas of the lower end surface of the sheet material and are relatively arranged. The fan 31 simultaneously sucks the multiple areas of the lower end surface of the sheet material through the second connecting pipeline 37 and the multiple sub-ventilation spaces 211, so that the carbon oil on the upper end surface of the sheet material can evenly penetrate into various areas of the lower end surface of the sheet material, thereby improving the processing quality of the sheet material.

[0058] Reference Figure 5 and Figure 8In some embodiments of the present application, a flow equalizer plate 24 is arranged in the gas disk 2. Specifically, along the first direction of the plate material filling hole setting, the flow equalizer plate 24 is horizontally arranged in the gas disk 2, and the flow equalizer plate 24 is provided with a plurality of flow equalizer holes 241 spaced apart along the radial direction of the circuit board carbon oil filling hole device 100, and along the height direction of the circuit board carbon oil filling hole device 100, the flow equalizer holes 241 penetrate the upper end surface of the flow equalizer plate 24 and the lower end surface of the flow equalizer plate 24.

[0059] Furthermore, the flow-uniform hole 241 is suitable for allowing gas to pass through, and the flow-uniform plate 24 is used to evenly distribute the flow direction of the gas. When the fan 31 sucks the sheet material through the gas disk 2, the flow-uniform plate 24 can evenly distribute the suction force of the fan 31 to various areas of the lower end surface of the sheet material, so that the carbon oil on the upper end surface of the sheet material can penetrate into the lower end surface of the sheet material as evenly as possible, thereby further improving the product quality of the sheet material.

[0060] Reference Figure 1-Figure 3 and Fig.11 In some embodiments of the present application, the circuit board carbon oil filling hole equipment 100 may also include: a scraping mechanism 4, the scraping mechanism 4 is arranged on the mounting frame 1, the scraping mechanism 4 includes a scraper 41, a first driving component 42, a second driving component 43 and a silk screen, the second driving component 43 is transmission-connected with the first driving component 42 and the scraper 41, the silk screen is arranged on the second driving component 43, the scraper 41 is located on the side of the silk screen away from the sheet material and is suitable for stopping with the silk screen, the first driving component 42 is used to drive the second driving component 43 to drive the scraper 41 and the silk screen to move closer to or away from the sheet material, and the second driving component 43 is used to drive the scraper 41 to move along the first direction of the circuit board carbon oil filling hole equipment 100.

[0061] Specifically, after the sheet material is placed on the upper end surface of the gas disk 2, along the height direction of the circuit board carbon oil filling device 100, the scraper 41 is located above the silk screen, and the sheet material is located below the silk screen, and the scraper 41 is stopped against the upper end wall of the silk screen, and the upper end wall of the silk screen is provided with carbon oil. The first drive component 42 drives the second drive component 43 to drive the scraper 41 and the silk screen to move close to the sheet material, so that the silk screen and the sheet material stop, and then the second drive component 43 drives the scraper 41 to reciprocate along the first direction of the circuit board carbon oil filling device 100, and the scraper 41 scrapes the carbon oil on the silk screen so that the carbon oil can be evenly distributed on the silk screen, and the carbon oil flows into the preset area of ​​the upper end wall of the sheet material through the preset holes of the silk screen, thereby achieving the technical effect of coating carbon oil only on the preset area of ​​the sheet material.

[0062] Furthermore, the scraper 41 and the screen printing plate evenly distribute the carbon oil to the preset area of ​​the upper end surface of the sheet material, so that the carbon oil can evenly penetrate into the preset area of ​​the lower end surface of the sheet material, thereby improving the processing quality of the carbon oil filling holes of the sheet material.

[0063] After the sheet material is processed, the first driving assembly 42 drives the second driving assembly 43 to drive the screen printing plate and the scraper 41 to move away from the sheet material.

[0064] It should be noted that the prefabricated holes of the sheet are only set in part of the sheet, the preset holes of the silk screen are opposite to the preset holes of the sheet, and the carbon oil on the silk screen flows through the preset holes of the silk screen into the area of ​​the sheet with the prefabricated holes.

[0065] Furthermore, a flexible silicone strip is provided on the end surface of the scraper 41 that contacts the screen printing plate.

[0066] Reference Figure 11-13 In some embodiments of the present application, the first driving assembly 42 includes a second driving member 421, a connecting member 422 and a transmission rod 423. Along the height direction of the circuit board carbon oil filling device 100, one of the first driving assembly 42 and the second driving assembly 43 is located above the other, one end of the connecting member 422 is connected and cooperated with the second driving member 421, and the other end of the connecting member 422 is pivotally connected to one end of the transmission rod 423, and the other end of the transmission rod 423 is pivotally connected to the second driving assembly 43. In some specific embodiments, the second drive component 43 is located above the first drive component 42, the second drive member 421 is arranged on the mounting frame 1, one end of the connecting member 422 is connected and cooperated with the output end of the second drive member 421, the other end of the connecting member 422 is pivotally connected to the lower end of the transmission rod 423, and the upper end of the transmission rod 423 is pivotally connected to the second drive component 43.

[0067] Furthermore, the second driving member 421 is used to drive the connecting member 422 to drive the transmission rod 423 to rotate around the central axis of the second driving member 421, and drive the other end of the transmission rod 423 to rotate around the pivot axis between the transmission rod 423 and the second driving assembly 43, so that the transmission rod 423 drives the second driving assembly 43 to move closer to or away from the sheet material.

[0068] Specifically, the second driving member 421 drives the connecting member 422 to rotate around the central axis of the output end of the second driving member 421. When the second driving member 421 drives the end of the connecting member 422 pivotally connected to the transmission rod 423 to rotate downward, the transmission rod 423 drives the second driving component 43 to move downward, and the second driving component 43 drives the scraper 41 to move closer to the sheet material. When the second driving member 421 drives the end of the connecting member 422 pivotally connected to the transmission rod 423 to rotate upward, the transmission rod 423 drives the second driving component 43 to move upward, and the second driving component 43 drives the scraper 41 to move away from the sheet material, thereby achieving the technical effect of the first driving component 42 driving the second driving component 43 to drive the scraper 41 to move closer to or away from the sheet material.

[0069] It should be noted that when the connecting member 422 drives the transmission rod 423 to move upward or downward, the end of the transmission rod 423 pivotally connected to the connecting member 422 rotates around the pivot axis between the transmission rod 423 and the connecting member 422, and the end of the transmission rod 423 pivotally connected to the second drive assembly 43 rotates around the pivot axis between the transmission rod 423 and the second drive assembly 43.

[0070] In some specific embodiments, the second driving member 421 may be a motor, but the present application is not limited thereto. The second driving member 421 may also be a hydraulic motor or the like.

[0071] Reference Figure 1-Figure 3 and Fig.11 In some embodiments of the present application, the second driving assembly 43 includes a connecting frame 431, a third driving member 432, a driving wheel 433, a driven wheel 434 and a transmission belt 435. The connecting frame 431 is transmission-connected to the first driving assembly 42. Specifically, the connecting frame 431 is pivotally connected to the end of the transmission rod 423 away from the connecting member 422, the third driving member 432 is arranged on the connecting frame 431, the driving wheel 433 and the driven wheel 434 are both pivotally mounted on the connecting frame 431, and the transmission belt 435 is wound around the driving wheel 433 and the driven wheel 434. On the outside of the moving wheel 434, the scraper 41 is connected and cooperated with the transmission belt 435. In some specific embodiments, the scraper 41 can be connected and cooperated with the upper end of the transmission belt 435. In other specific embodiments, the scraper 41 can also be connected and cooperated with the lower end of the transmission belt 435. The third driving member 432 is connected and cooperated with the active wheel 433. The third driving member 432 is used to drive the active wheel 433 to drive the transmission belt 435 to rotate, so that the transmission belt 435 drives the scraper 41 to move along the first direction of the circuit board carbon oil filling device 100.

[0072] It should be noted that the transmission belt 435 drives the scraper 41 to reciprocate between the driving wheel 433 and the driven wheel 434, and the connection between the scraper 41 and the transmission belt 435 cannot bypass the driving wheel 433 and the driven wheel 434. That is to say, when the scraper 41 is connected and cooperated with the upper end of the transmission belt 435, the connection between the scraper 41 and the upper end of the transmission belt 435 can only reciprocate linearly between the driving wheel 433 and the driven wheel 434, and the connection between the scraper 41 and the upper end of the transmission belt 435 cannot bypass the driving wheel 433 and the driven wheel 434 to perform circular motion.

[0073] Specifically, the third driving member 432 drives the driving wheel 433 to rotate around the central axis of the third driving member 432, the driving wheel 433 drives the transmission belt 435 to rotate around the driving wheel 433 and the driven wheel 434, and the transmission belt 435 drives the scraper 41 to reciprocate between the left end portion of the sheet and the right end portion of the sheet, thereby achieving the technical effect that the scraper 41 scrapes the carbon oil on the upper end surface of the sheet to various areas of the upper end surface of the sheet.

[0074] In some specific embodiments, the third driving component 432 may be a motor, but the present application is not limited thereto. The third driving component 432 may also be a hydraulic motor or the like.

[0075] In some specific embodiments, both the driving wheel 433 and the driven wheel 434 may be synchronous wheels, and the transmission belt 435 may be a synchronous belt.

[0076] Reference Figure 1 and Figure 4 In some embodiments of the present application, the scraping mechanism 4 may further include: a fourth driving member 44, the fourth driving member 44 is transmission-connected to the second driving assembly 43, the scraper 41 is connected and cooperated with the fourth driving member 44, the fourth driving member 44 is used to drive the scraper 41 to move closer to or away from the silk screen screen, and the second driving assembly 43 drives the fourth driving member 44 to drive the scraper 41 to move along the first direction of the circuit board carbon oil filling device 100.

[0077] A prefabricated hole is provided in a preset area of ​​the upper end wall of the sheet material, and the positions of the preset holes of different sheets are different. Different sheets have corresponding silk screen screens of different sheets. When replacing the silk screen screen, the fourth driving member 44 drives the scraper 41 to move away from the silk screen screen to separate the scraper 41 from the silk screen, so that the corresponding silk screen screen can be disassembled and replaced. After replacing the preset silk screen screen, the fourth driving member 44 drives the scraper 41 to move close to the silk screen screen to stop the scraper 41 from the silk screen, thereby achieving the technical effect of stopping or separating the scraper 41 from the silk screen.

[0078] In some specific embodiments, the fourth driving member 44 may be a linear motor, but the present application is not limited thereto. The fourth driving member 44 may also be an electric push rod, etc.

[0079] Reference Figure 1 , Fig.11 and Fig.14 In some embodiments of the present application, the scraping mechanism 4 may further include: a detection switch 45, a protective frame 46 and a controller. The protective frame 46 is pivotally connected to the second driving assembly 43. The protective frame 46 is arranged on the outside of the gas disk 2 and the scraper 41. Specifically, the protective frame 46 is pivotally connected to the outer peripheral wall of the connecting frame 431. Along the radial direction of the circuit board carbon oil filling device 100 from the inside to the outside, the gas disk 2 and the scraper 41 are both located on the inner side of the protective frame 46.

[0080] In addition, the protective frame 46 is engaged with the trigger part 451 of the detection switch 45, and the controller is communicatively connected with the detection switch 45, the first drive component 42 and the second drive component 43. When the protective frame 46 is driven to rotate around the pivot axis of the protective frame 46, the protective frame 46 triggers the trigger part 451, and the controller is used to control the first drive component 42 and the second drive component 43 to stop working according to the detection signal of the detection switch 45.

[0081] Specifically, when the first driving component 42 drives the scraper 41 and the protective frame 46 to move close to the sheet material, and the worker's hand is not separated from the sheet material, the worker's hand touches the protective frame 46 and drives the protective frame 46 to rotate around the pivot axis between the protective frame 46 and the connecting frame 431 close to the trigger part 451 of the detection switch 45, and the protective frame 46 triggers the trigger part 451 of the detection switch 45, and the detection switch 45 generates a detection signal. The controller controls the first driving component 42 and the second driving component 43 to stop working according to the detection signal of the detection switch 45, thereby preventing the worker's hand from being scratched by the scraper 41, thereby improving the safety of the circuit board carbon oil filling equipment 100.

[0082] In addition, the protection frame 46 is tilted toward the trigger part 451 of the detection switch 45 , so as to avoid a dead point between the worker's hand and the protection frame 46 , and prevent the protection frame 46 from being unable to rotate close to the trigger part 451 of the detection switch 45 .

[0083] Furthermore, the connection frame 431 is provided with a limit member 436, and the limit member 436 cooperates with the protection frame 46 to limit the position. Fig.14 In the illustrated embodiment, along the second direction of the circuit board carbon oil hole filling device 100, the limiter 436 is located behind the protective frame 46, and the trigger portion 451 of the detection switch 45 is located in front of the protective frame 46. The limiter 436 is used to prevent the protective frame 46 from rotating around the pivot axis between the protective frame 46 and the connecting frame 431 close to the limiter 436, so that when the protective frame 46 touches the worker's hand, the protective frame 46 can only move toward the trigger portion 451 of the detection switch 45, thereby improving the working reliability of the circuit board carbon oil hole filling device 100. The second direction of the circuit board carbon oil hole filling device 100 can refer to Figure 1 The front-to-back direction.

[0084] In some specific embodiments, the detection switch 45 may be a micro switch, but the present application is not limited thereto. The detection switch 45 may also be a pressure switch or the like.

[0085] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
