Description
Technical Field
[0001] The invention relates to the technical field of dust removal during motor substrate processing, in particular to an integrated automatic dust removal device for substrates. Background Art
[0002] Electronic substrates, also known as printed circuit boards (PCBs), are indispensable core components in modern electronic devices. The structure of an electronic substrate usually includes a substrate, a conductive layer, and a solder mask layer. The substrate is made of insulating material, and the conductive layer is made of copper foil to form a circuit pattern. The solder mask is used to protect the copper foil from oxidation and is generally green. Since electronic substrates are used in high-precision electronic fields, there are extremely high requirements for environmental cleanliness when processing them. When processing the substrates, they need to be dusted. As companies pay more attention to environmental hygiene and the health of employees, the traditional use of air guns and brushes to remove substrate dust will cause dust to fly everywhere, resulting in the production workshop not meeting the air cleanliness requirements of customers. In addition, the substrates processed in the production workshop are equipped with optical ports, which have very high requirements for air cleanliness.
[0003] The existing patent authorization number is: CN112367770B, which discloses an effective dust removal device for PCB board production, including: a workbench, with a cylinder installed on one side of the upper part of the workbench; a blowing device, with a blowing device provided on the middle part of the upper part of the workbench; a cleaning device, with a cleaning device provided on one side of the workbench. The invention unlocks and releases the PCB board by moving the third connecting rod to the right to cooperate with the third wedge block, pushing the fourth wedge block to move outward, and then letting go. Under the action of the third spring, the pressing plate is pushed inward to clamp the PCB board, achieving the effect of easily clamping and fixing the PCB board after dust removal, preventing the PCB board from falling directly and causing damage. After analyzing the above invention, the following problems were found: (1) The simple cleaning device lacks a multi-directional cleaning function when in contact with the PCB board, resulting in the inability to effectively remove some dust impurities with strong adhesion; The cleaning device and the PCB board transfer are all equipped with independent power devices. There is a lack of kinetic energy transmission between the various structures, resulting in high overall energy consumption and not conducive to energy-saving and efficient production. Therefore, in view of the above-mentioned problems, the present technical solution proposes an integrated device for automatic dust removal of substrates. Summary of the Invention
[0004] The object of the present invention is to provide an integrated device for automatic dust removal of substrates to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an integrated device for automatic dust removal of substrates, comprising a dust removal box forming a space for automatic dust removal of electronic substrates; The dust filter bottom box is connected to the bottom of the dust box and is used to absorb the gas after dust removal inside the dust box and filter it. A set of back-blowing dust collectors are installed inside the dust filter bottom box. The top of the back-blowing dust collector is connected to the bottom of the dust box. A dust removal fan is installed inside the back-blowing dust collector to form a negative pressure at the connection between the back-blowing dust collector and the bottom of the dust box, absorbing the mixed gas after filtering and dust removal, and discharging it cleanly. The electronic substrate dust removal net table is cyclically and laterally moved and arranged inside the dust removal box for carrying the electronic substrate for cyclic and movable dust removal. A cyclic feeding mechanism is connected to the bottom of the electronic substrate dust removal net table, and the cyclic feeding mechanism drives the electronic substrate dust removal net table to be placed in the dust removal box for cyclic reciprocating movement. A vibrating rotary cleaning mechanism is arranged above the middle of the dust removal box, and the bottom of the vibrating rotary cleaning mechanism contacts the upper surface of the electronic substrate dust removal net table. The vibration direction of the vibrating rotary cleaning mechanism is perpendicular to the moving direction of the electronic substrate dust removal net table. In conjunction with the cyclic reciprocating movement of the electronic substrate dust removal net table, the electronic substrate placed on the electronic substrate dust removal net table is continuously rotated and cleaned in multiple directions, thereby fully improving the dust removal and cleaning effect of the electronic substrate; the two sides of the vibrating rotary cleaning mechanism are rotatably connected to the driving end of the cyclic feeding mechanism through a transmission connecting member and a vibration connecting member, that is, while the cyclic feeding mechanism drives the electronic substrate dust removal net table to cyclically move, the transmission connecting member and the vibration connecting member drive the vibrating rotary cleaning mechanism to rotate and vibrate synchronously, thereby rotationally cleaning the electronic substrate on the electronic substrate dust removal net table; The pneumatic dust removal unit is distributed around the electronic substrate dust removal net table. It uses high pressure combined with the cleaning of the vibrating rotary cleaning mechanism to control the dust on the electronic substrate to be in a suspended state. Then, under the negative pressure absorption at the top of the back-blowing dust collector, it is transferred to the back-blowing dust collector for filtration. The pneumatic dust removal unit includes a top dust removal air duct that is interconnected and distributed above the electronic substrate dust removal net table and a lower dust removal air duct on the front and rear sides of the lower part of the electronic substrate dust removal net table. The top dust removal air duct discharges air from top to bottom to the electronic substrate, and the lower dust removal air duct discharges air from the front and rear sides of the lower part of the electronic substrate dust removal net table to the bottom of the electronic substrate dust removal net table, thereby blowing the dust on the upper and lower sides of the electronic substrate dust removal net table and separating it from the electronic substrate. The air intake compression mechanism is arranged on one side of the dust filter bottom box. The output end of the air intake compression mechanism is connected to the pneumatic dust removal unit. The top side of the air intake compression mechanism is rotatably connected to the driving end of the circulating feed mechanism through a circulating swinging member. That is, when the circulating feed mechanism is running, the air intake compression mechanism is synchronously driven to run, thereby providing gas transmission for the pneumatic dust removal unit.
[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: a group of servo motors are provided to drive the electronic substrate dust removal net table to move back and forth cyclically, thereby driving the electronic substrates on the electronic substrate dust removal net table to move back and forth continuously; a brush is provided above the electronic substrate dust removal net table for performing multi-directional rotational cleaning on the electronic substrates on the electronic substrate dust removal net table; and multiple groups of dust removal wind rods are provided around the electronic substrate dust removal net table to blow air toward it, thereby removing dust attached to the electronic substrates; and then, in cooperation with the brushes, the dust gas removed is transferred to the back-blowing dust collector for filtering treatment again through the adsorption force at the hood opening, thereby achieving efficient and automatic dust removal of the electronic substrates; By setting up a group of servo motors to drive the electronic substrate dust removal network table to move in a circular motion, and then under the connection of the transmission belt, synchronously driving the brush to rotate, and controlling the vibration of the brush in the front and back directions, and driving the input and output of gas inside the piston cylinder, it is possible to utilize a single group of motors and coordinate the connection and coordination between the structures to achieve full conversion and utilization of kinetic energy, ensuring efficient dust removal of the electronic substrate while greatly reducing the energy consumption of the device and improving energy saving.

[0012] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0013] See also Figure 1-Figure 5 , an integrated device for automatic dust removal of substrates, comprising a dust removal box 10, forming a space for automatic dust removal of electronic substrates; The dust filter bottom box 11 is connected to the bottom of the dust box 10 and is used to absorb the dust-removed gas inside the dust box 10 and filter it. A set of back-blowing dust collectors 13 are installed inside the dust filter bottom box 11. The top of the back-blowing dust collector 13 is connected to the bottom of the dust box 10. A dust removal fan is installed inside the back-blowing dust collector 13 to form a negative pressure at the connection between the back-blowing dust collector 13 and the bottom of the dust box 10, so as to absorb the mixed gas after filtering and dust removal and discharge it cleanly. The electronic substrate dust removal net table 19 is arranged inside the dust removal box 10 for cyclical and horizontal movement, and is used for carrying the electronic substrate for cyclical and mobile dust removal. The bottom of the electronic substrate dust removal net table 19 is connected with a cyclic feeding mechanism, which drives the electronic substrate dust removal net table 19 to be placed inside the dust removal box 10 for cyclical and reciprocating movement. A vibrating rotary cleaning mechanism is arranged above the middle of the dust removal box 10. The bottom of the vibrating rotary cleaning mechanism contacts the upper surface of the electronic substrate dust removal net table 19. The vibration direction of the vibrating rotary cleaning mechanism is perpendicular to the moving direction of the electronic substrate dust removal net table 19, and cooperates with the electronic substrate removal. The reciprocating movement of the dust net table 19 performs multi-directional continuous rotational cleaning on the electronic substrates placed on the electronic substrate dust removal net table 19, thereby fully improving the dust removal and cleaning effect on the electronic substrates; the two sides of the vibrating rotary cleaning mechanism are respectively connected to the driving end of the cyclic feeding mechanism through a transmission connection and a vibration connection. That is, while the cyclic feeding mechanism drives the electronic substrate dust removal net table 19 to cyclically move, the transmission connection and the vibration connection drive the vibrating rotary cleaning mechanism to rotate and vibrate synchronously, thereby performing rotational cleaning on the electronic substrates on the electronic substrate dust removal net table 19; The pneumatic dust removal unit is distributed around the electronic substrate dust removal network platform 19, and uses high pressure combined with the cleaning of the vibrating rotary cleaning mechanism to control the dust on the electronic substrate to be in a suspended state, and then is transferred to the back-blowing dust collector 13 under the negative pressure absorption at the top of the back-blowing dust collector 13 for filtration treatment. The pneumatic dust removal unit includes a top dust removal air duct that is interconnected and distributed above the electronic substrate dust removal network platform 19 and a lower dust removal air duct on the front and rear sides of the lower part of the electronic substrate dust removal network platform 19. The top dust removal air duct discharges air from top to bottom to the electronic substrate, and the lower dust removal air duct discharges air from the front and rear sides of the lower part of the electronic substrate dust removal network platform 19 to the bottom of the electronic substrate dust removal network platform 19, thereby blowing the dust on the upper and lower surfaces of the electronic substrate dust removal network platform 19 and separating it from the electronic substrate. The air intake compression mechanism is arranged on one side of the dust filter bottom box 11. The output end of the air intake compression mechanism is connected to the pneumatic dust removal unit. The top side of the air intake compression mechanism is rotatably connected to the driving end of the circulating feed mechanism through a circulating swinging member. That is, when the circulating feed mechanism is running, the air intake compression mechanism is synchronously driven to run, thereby providing gas transmission for the pneumatic dust removal unit.
[0014] In the embodiment of the present invention, the dust removal box 10 is set to a rectangular structure, and an electronic substrate inlet and outlet 14 is opened on one side wall of the dust removal box 10. The electronic substrate inlet and outlet 14 is used to move the electronic substrate in and out of the dust removal box 10. The opening width of the electronic substrate inlet and outlet 14 is greater than the sum of the thicknesses of the electronic substrate dust removal net 19 and the electronic substrate, which is convenient for directly controlling the automatic entry and exit of the electronic substrate in and out of the dust removal box 10 under the transportation of the circulating feeding mechanism. Rubber baffles are symmetrically swingingly set on the upper and lower sides of the electronic substrate inlet and outlet 14. When the rubber baffle is in a free state, it can keep the electronic substrate in the dust removal box 10. The vertical position is kept low, and the possibility of external dust entering the dust removal box 10 along the electronic substrate inlet and outlet 14 is reduced without affecting the electronic substrate dust removal net platform 19 and the electronic substrate inlet and outlet 14; a visual window is provided on the wall of the dust removal box 10 on the side opposite to the electronic substrate inlet and outlet 14, so that the staff can directly observe the operating conditions inside the dust removal box 10, and a push-pull manual operation door 15 is provided on the rear side of the dust removal box 10. The setting of the manual operation door 15 is used to provide the possibility for the staff to repair, operate, and adjust the internal components of the dust removal box 10; The four corners of the bottom of the dust filter bottom box 11 are fixedly installed with support legs 12, and the support legs 12 are used to increase the support stability of the dust filter bottom box 11. At the same time, cover openings 16 are symmetrically opened on the front and back sides of the dust box 10. The bottom of the cover opening 16 is connected to a dust discharge channel 17 with a V-shaped structure. The bottoms of the dust discharge channels 17 on both sides are commonly connected to a collecting channel 18. The bottom end of the collecting channel 18 is connected to the top of the back-blowing dust collector 13. That is, under the connection of the dust discharge channel 17 and the collecting channel 18, the dust gas formed inside the dust box 10 is conveniently transferred to the inside of the back-blowing dust collector 13. The dust removal fan is arranged at the upper inner side of the back-blowing dust collector 13 to facilitate the generation of sufficient adsorption force close to the cover opening 16; Among them, the back-blowing dust collector 13 belongs to the prior art. The back-blowing dust collector 13 includes a filter element, a compressed air system, a control system, etc. It uses the airflow generated by compressed air or a fan to blow out dust in a direction opposite to the normal dust suction direction, thereby achieving the purpose of cleaning. It will not be described in detail here. It should be noted that the dust removal box 10 and the dust filter bottom box 11 in the present drawing are drawn in an internally cutaway form, so as to intuitively display the internal structural components of the dust removal box 10 .
[0015] In one embodiment of the present invention, elastic positioning members 24 are symmetrically installed on both sides of the front and rear parts of the electronic substrate dust removal net 19. The elastic positioning members 24 are used to press and position the electronic substrate placed on the electronic substrate dust removal net 19. Figure 8 The elastic positioning member 24 includes an extended fixing plate 242 fixed on the side wall of the electronic substrate dust removal net platform 19, and the top of the extended fixing plate 242 is telescopically connected to a telescopic rod 241. A waist-shaped pressure plate 240 is fixedly installed on the top of the telescopic rod 241, and the end of the waist-shaped pressure plate 240 extends toward the middle of the electronic substrate dust removal net platform 19. A sleeve spring 243 is set on the telescopic rod 241 between the waist-shaped pressure plate 240 and the extended fixing plate 242. The extended section of the waist-shaped pressure plate 240 and the elastic action of the sleeve spring 243 are used to press the edges of the electronic substrates placed between the four groups of waist-shaped pressure plates 240. Since the positioning of the electronic substrate is only for dust removal, it does not require excessive fastening force. The elastic force of the elastic positioning member 24 is simultaneously used to expand the applicable range of positioning of electronic substrates within a certain thickness.
[0016] As a preferred embodiment of the present invention, the circulating feeding mechanism includes a connecting block 21 fixed to the middle part of the bottom of the electronic substrate dust removal network platform 19, the bottom end of the connecting block 21 is fixedly connected to a nut I, the middle part of the nut I is horizontally threadedly connected to a screw I 20, and the nut I is provided with a guide device for limiting its rotation, and the two ends of the screw I 20 are fixed to the bottom of the dust removal box 10 through a support sleeve rod, wherein one end of the screw I 20 is connected to an output shaft 22, and the end of the output shaft 22 is connected to a servo motor 23 whose bottom is fixed on the dust removal box 10. The servo motor 23 is started to drive the output shaft 22 to rotate, thereby driving the screw I 20 to rotate, thereby controlling the nut I to move back and forth along the screw I 20, and then under the connection of the connecting block 21, the electronic substrate dust removal network platform 19 is controlled to move horizontally along the inside of the dust removal box 10.
[0017] As a preferred embodiment of the present invention, see Figure 6 The vibrating rotary cleaning mechanism includes two groups of rectangular cleaning brush bases 25, which are spaced apart. An axis plate 26 is fixedly installed inside the cleaning brush base 25. A plurality of rotating shafts 29 are rotatably installed at equal intervals on the bottom of the axis plate 26 along the length direction. A brush mounting cylinder 27 is fixedly installed at the bottom of the rotating shaft 29. The bottom of the brush mounting cylinder 27 is set to an open shape and evenly distributed brushes 28 are installed inside. When the rotating shaft 29 rotates, the brushes 28 are driven to rotate synchronously by the connection of the brush mounting cylinder 27, so as to perform rotary cleaning on the electronic substrate placed on the electronic substrate dust removal net table 19. See Figure 7 、 Figure 9 Adjacent rotating shafts 29 are connected by a transmission chain 30. A helical gear I 31 is fixedly installed in the middle of the rotating shaft 29 near the transmission connecting member. A helical gear II 32 is vertically meshed on the outer side of the helical gear I 31. The outer side of the helical gear II 32 is connected to the transmission connecting member. One side of the transmission connecting member is rotatably connected to the output shaft 22. That is, under the operation of the output shaft 22, the power transmission of the transmission connecting member is coordinated to drive the helical gear II 32 to control the rotation of the helical gear I 31. Then, under the connection of multiple transmission chains 30, the rotating shaft 29 is synchronously driven to rotate, thereby controlling the rotation of the brush 28 at the bottom of the brush mounting cylinder 27. Specifically, the transmission connection includes a buffer rod 33 fixed to the middle part of the outer end of the helical gear II 32, the end of the buffer rod 33 is limitedly and telescopically connected to the buffer cylinder 34, the end of the buffer cylinder 34 is connected to the driving wheel rod 42, and the driving wheel rods 42 on both sides are connected by a transmission belt I 43. The driving wheel rod 42 facing the output shaft 22 is obliquely connected to the transmission belt III downward, and the end of the transmission belt III is connected to the rotating shaft 44. The end of the rotating shaft 44 extends to the output shaft 22 and is installed with a helical gear III 45. One side of the helical gear III 45 is vertically meshed with a helical gear IV 46 fixed to the output shaft 22. That is, when the output shaft 22 is running, the two sets of driving wheel rods 42 are driven to rotate under the transmission of the helical gear IV 46, the helical gear III 45, the rotating shaft 44, the transmission belt III, and the transmission belt I 43; Specifically, the end of the buffer rod 33 placed inside the buffer cylinder 34 is elastically connected to a buffer spring 35, and a positioning key 36 is installed on the circumferential outer wall of the buffer rod 33. A positioning slide rail is provided on the inner wall of the buffer cylinder 34 corresponding to the positioning key 36. The positioning key 36 is placed in the positioning slide rail and slides axially. The positioning key 36 and the positioning slide rail are restricted to keep the buffer cylinder 34 rotating, and the buffer rod 33 is synchronously driven to rotate. Then, under the connection of the bevel gear II 32 and the bevel gear I 31, the rotating shaft 29 is driven to rotate. The expansion and contraction of the buffer rod 33 in the buffer cylinder 34 and the elastic action of the buffer spring 35 provide a buffer distance for the cleaning brush base 25 to drive the overall brush 28 to vibrate in the front and rear directions. Specifically, the end of the driving wheel rod 42 extends outward and is connected to a support rod, and the end of the support rod is downwardly connected to a support column whose bottom end is fixed to the bottom of the dust removal box 10. Under the action of the support column and the support rod, the driving wheel rod 42, the buffer cylinder 34, the buffer rod 33 and other structures are controlled to operate in the air; Specifically, the vibration connecting member includes an arc-shaped force-bearing push block 37 fixed to the other end of the cleaning brush base 25, and a push block 40 is provided on the outside of the force-bearing push block 37 on both sides for lateral movement.

A guide device for limiting its rotation is provided on the nut II 39, and one end of the screw II 38 is connected to a guide rod, which is supported and positioned downward by a support sleeve rod. The other end of the screw II 38 is connected to a connecting shaft 41, and the end of the connecting shaft 41 extends laterally to the output shaft 22. A transmission belt IV is rotatably connected between the connecting shaft 41 and the output shaft 22. Under the rotation of the output shaft 22, the transmission belt IV drives the connecting shaft 41 to drive the screw II 3 8 rotates, thereby controlling the nut II 39 to move back and forth along the lead screw II 38, thereby driving the push block 40 to move back and forth between the force-bearing push blocks 37 on both sides. The push block 40 pushes the force-bearing push block 37 laterally, in conjunction with the elastic effect of the buffer spring 35, to control the back and forth lateral movement of the cleaning brush base 25 on both sides, thereby controlling the bottom brush 28 to move synchronously in the front and rear directions when cleaning the electronic substrate, thereby increasing the cleaning angle range of the brush 28 for the electronic substrate, that is, by utilizing the lateral cyclic reciprocating movement of the electronic substrate dust removal net platform 19, in conjunction with the rotation and continuous back and forth vibration of the brush 28, a certain cleaning force can be applied when cleaning the electronic substrate on the electronic substrate dust removal net platform 19, thereby improving the dust removal and cleaning effect; It should be noted that the length of the cleaning brush base 25 is greater than the width of the electronic substrate dust removal platform 19. The purpose is to maintain the cleaning range formed by the multiple groups of brushes 28 at the bottom, which can cover the width of the electronic substrate placed on the electronic substrate dust removal platform 19 and fully clean and dust it.

That is, when the output shaft 22 rotates, the transmission belt II 65 is used to drive the main rotating shaft 64 to rotate, thereby driving the auxiliary rotating shafts 63 on both sides to rotate. Then, under the connection of the U-shaped frame and the convex swing frame 62, the lifting and swinging rod 61 is driven to continuously lift and swing. Then, under the rolling connection of the connecting ball 60, the piston plate 58 is controlled to circulate up and down along the inside of the piston cylinder 55, compressing and releasing the bottom of the piston cylinder 55. Specifically, an air inlet is provided on one side of the bottom of the two groups of piston cylinders 55. The air inlet is connected to an air inlet pipe toward the outside of the dust filter bottom box 11, and the air inlet pipe is used to transmit external air to the piston cylinder 55. An air outlet sealing plate is swingably provided on one side of the air inlet toward the inside of the piston cylinder 55. When the piston plate 58 moves upward, an upward adsorption force is generated. At this time, the air outlet sealing plate is opened, and external air is input to the bottom of the piston cylinder 55 along the air inlet pipe and the air inlet. An air outlet is provided on the other side of the bottom of the two groups of piston cylinders 55. One side of the air outlet is connected to an air outlet pipe 57. The end of the air outlet pipe 57 is connected to an air intake transmission pipe 54 distributed in the wall of the gas transmission box. The top moves through the bottom of the dust removal box 10 to communicate with the transmission pipe 53 in the lower dust removal air exhaust. An air inlet sealing plate is swingably provided on the outer side of the air outlet. When the external gas enters the bottom of the piston cylinder 55, the piston plate 58 descends to generate downward pressure on the gas. At this time, the air outlet sealing plate is forced to seal the air inlet, and the air inlet sealing plate is forced to open. At this time, the air outlet is opened, and then the gas is pressed into the air outlet pipe 57, and then transmitted to the transmission pipe 53 through the air inlet transmission pipe 54. As the piston plate 58 continues to rise and fall, the external air can be continuously transmitted to the transmission pipe 53, thereby realizing the function of controlling the gas transmission flow by utilizing the operation of the servo motor 23; The tops of the air inlet sealing plate and the air outlet sealing plate are both rotatably arranged at the corresponding air inlet and air outlet via a rotating shaft, and a spring is arranged on the rotating shaft to keep the air inlet sealing plate and the air outlet sealing plate in contact with the corresponding air outlet and air inlet when in a free state; Specifically, a multi-layer filtering dust removal screen is provided in the air inlet pipe to remove impurities and dust in the external air, thereby ensuring that the gas input into the dust removal box 10 is clean and preventing contamination of the electronic substrate to be dusted.
[0020] The working principle of the present invention is: in the idle position of the device, all the driving parts mentioned above, which refer to power elements, electrical components and adapted power supplies, are connected through wires, and the electrical connections are completed in a working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, the electronic substrate to be dusted is placed on the electronic substrate dust removal table 19 along the electronic substrate inlet and outlet 14, and then the four groups of waist-shaped pressure plates 240 on the electronic substrate dust removal table 19 are used to elastically press it, and then the servo motor 23 is driven to drive the output shaft 22 to rotate, and synchronously drive the lead screw I 20 to rotate, thereby driving the nut I to move back and forth in a cycle, and then driving the electronic substrate dust removal table 19 to rotate and move back and forth, driving the electronic substrate on the electronic substrate dust removal table 19 to move back and forth. At this time, under the connection of the transmission belt III and the transmission belt IV, the connecting shaft 41 is driven to rotate, and then the push block 40 is controlled to push the force-bearing push block 37 at the end of the two groups of cleaning brush bases 25. The brush 28 is pushed intermittently, and then cooperates with the buffer spring 35 at the other end of the cleaning brush base 25 to control the continuous vibration of the brush 28, and drives the buffer rod 33 to rotate under the connection of the driving wheel rod 42 and the transmission belt I 43, and then drives the brush 28 to rotate under the transmission of the transmission chain 30, thereby coordinating the back and forth vibration of the brush 28 and the cyclic movement of the electronic substrate dust removal network platform 19, driving the brush 28 to clean the electronic substrate placed on the electronic substrate dust removal network platform 19 at multiple angles and within the full range. Under the connection of the ring swing part, the two groups of piston cylinders 55 are controlled to operate, and the gas outside the dust filter bottom box 11 is transmitted to the air intake transmission pipe 54, and then transferred to the transmission pipe 53, and then transmitted to the top dust removal wind rod I47, the top dust removal wind rod II48, the top dust removal wind rod III49, the lower dust removal wind rod I51, and the lower dust removal wind rod II52, and blown up from multiple angles of the electronic substrate to suspend the dust, and then transferred to the back-blowing dust collector 13 for filtration under the adsorption in the hood 16.
