[0011] In one of the embodiments, the purging device further includes a suspension mechanism, which is used to suspend and install the bracket and enable the bracket to reciprocate in a vertical direction to adjust the height of the bracket.

[0012] In one embodiment, the suspension mechanism includes a mounting portion and a stop screw, one end of the stop screw is passed through the bracket, and the other end is connected to the mounting portion. When the stop screw rotates, the bracket moves back and forth in a vertical direction relative to the stop screw.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0025] For details, please refer to Figure 1 As shown, an automatic blowing system provided by an embodiment of the present invention is used to automatically blow the glass 10 in the process of transmission to clean the surface of the glass 10. In this embodiment, the glass 10 is formed by breaking (or cutting) a large glass substrate, and multiple independent glass 10 are sequentially transmitted through the transmission device 20 for continuous operation.

[0026] Specifically, in this embodiment, the glass 10 is electronic glass used in the fields of electronics, microelectronics, and optoelectronics. The transmission device 20 includes a transmission roller 22, which is formed by a plurality of transmission rollers 24 arranged at intervals. The glass 10 is laid on the transmission roller 22 and is transmitted by the rotation of the transmission roller 24. More specifically, the first direction is defined as the transport direction of the transmission roller 22, and the second direction is parallel to the plane where the glass 10 is transmitted through the transmission roller 22 and is perpendicular to the first direction. Figure 1 The direction of the arrow is the first direction.

[0027] The automatic purging system includes a purging device 30 and a control device 40. The purging device 30 is installed corresponding to the transmission device 20 to form a purging area 31 for cleaning the glass 10 in a certain area of ​​the transmission roller 24 of the transmission device 20.

[0028] Specifically, the purging device 30 includes a bracket 100, a purging mechanism 200 and an air supply mechanism 300. The bracket 100 is suspended on the conveying roller 24. The purging mechanism 200 is installed on the bracket 100, and a purging area 31 for cleaning the glass 10 is formed above the conveying roller 24 of the conveying device 20. The air supply mechanism 300 is connected to the purging mechanism 200 to provide the purging mechanism 200 with gas for cleaning the glass 10.

[0029] The control device 40 is used to detect whether there is a glass 10 in the purge area 31, so as to turn on or off the purge device 30 accordingly. When there is a glass 10 in the purge area 31, the control device 40 turns on the purge device 30 so that the purge device 30 purges and cleans the glass in the purge area 31. When there is no glass 10 in the purge area 31, the control device 40 turns off the purge device 30 so that the purge device 30 stops working, thereby avoiding wasting gas used for purge.

[0030] In this embodiment, the control device 40 includes a switch unit 41, a sensing unit 42 and a timing unit 43. The switch unit 41 is used to connect the purge device 30 to control the opening and closing of the purge device 30. When the switch unit 41 is turned on, the purge device 30 starts to work accordingly, and when the switch unit 41 is turned off, the purge device 30 stops working accordingly. The sensing unit 42 is arranged at the edge of the purge area 31 (i.e., the junction of the purge area 31 and the non-purge area), and is connected to the switch unit 41 for communication, and is used to detect whether a glass 10 enters the purge area 31. When the sensing unit 42 detects that the glass 10 enters the purge area 31, the switch unit 41 is turned on to start the purge device 30. The timing unit 43 is connected to the switch unit 41 for communication, and is used to delay the closing of the switch unit 41 to stop the purge device 30 from working whenever the switch unit 41 is turned on.

[0031] That is, in this embodiment, the timing unit 43 starts timing when the sensing unit 42 detects that the glass 10 enters the purge area 31, and after a preset fixed time, the switch unit 41 is closed. During this period of time, the control device 40 believes that there is glass 10 in the purge area 31. In actual applications, in order to have a good cleaning effect, after determining the moving speed of the glass 10, after a preset fixed time, the glass 10 is located outside the edge of the purge area 31 away from the sensing unit 42 and is separated by a certain distance. That is, after the glass 10 leaves the purge area 31, the purge device 30 will continue to work for a short period of time to avoid the situation where the glass 10 has not left the purge area 31, and the purge device 30 stops working, affecting the cleaning effect. Of course, the most ideal state is that after the preset fixed time, the glass 10 just leaves the purge area 31, at which time it has a good cleaning effect and can avoid the waste of gas used for purging to the greatest extent. Specifically, the switch unit 41, the sensing unit 42 and the timing unit 43 can establish a communication connection through the control circuit.

[0032] In this embodiment, the air supply mechanism 300 is provided with a gas transmission pipe 310 connected to the purge mechanism 200 to transmit gas. The switch unit 40 is a solenoid valve, which is arranged on the gas transmission pipe 310. When the solenoid valve receives a communication signal to open, the purge device 30 starts to work accordingly, and the gas in the air supply mechanism 300 enters the purge mechanism 300 and is blown out through the purge mechanism 300; when the solenoid valve receives a communication signal to close, the gas in the air supply mechanism 300 is intercepted, that is, the purge device 30 stops working accordingly.

[0033] More specifically, the sensing unit 42 is a photoelectric sensor, and the timing unit 43 is a time relay. Along the first direction, the opening time of the purge device 30 can be set by adjusting the relative position of the sensing unit 42, and the closing time of the purge device 30 can be set by adjusting the delay time of the timing unit 43.

[0034] For details, please refer to Figure 1 As shown, the glass 10 is a rectangular structure, and the purge area 31 is also a similar rectangular structure. The sensing unit 42 is correspondingly arranged at the first edge 31a of the purge area 31, and the glass 10 enters the purge area 31 through the first edge 31a. The time t from the glass 10 entering the purge area 31 from the first edge 31a to the glass 10 just leaving the purge area 31 is:

[0035] t=(L 1 +L 2 ) / v

[0036] Among them, L 1 is the length of the glass 10 along the first direction, L 2is the maximum length of the purge area 31 along the first direction, and v is the transmission speed of the glass 10 along the first direction. The delay time set by the timing unit 43 is greater than or equal to t. When the delay time set by the timing unit 43 is equal to t, the purge device 31 starts working immediately when the glass 10 enters the purge area 31, and the purge device 31 stops working immediately when the glass 10 leaves the purge area 31. Preferably, in this embodiment, the delay time of the timing unit 43 is 1.05-1.2 times t.

[0037] For details, please refer to Figure 2 and Figure 3 As shown, in the purge device 30, the bracket 100 is provided with a mounting hole 120 for installing the purge mechanism 200. The purge mechanism 200 includes a support rod 210 and a tuyere 220. The support rod 210 is inserted into the mounting hole 120. The support rod 210 is provided with a through shaft hole 212 to form a ventilation duct 214. The tuyere 220 is connected and fixed to one end of the support rod 210 and is arranged at an angle to the support rod 210. At the same time, the tuyere 220 is connected to the ventilation duct 214 of the support rod 210. The air supply mechanism 300 passes the gas into the ventilation duct 214 and then blows it out through the tuyere 220.

[0038] Furthermore, there are multiple mounting holes 120, which are arranged at intervals along the second direction on the bracket 100, so that multiple support rods 210 are respectively inserted into the multiple mounting holes 120 along the second direction. There are also multiple nozzles 220, which are connected to the support rods 210 one by one.

[0039] Specifically, in this embodiment, the support rod 210 is perpendicular to the plane where the glass 10 is located, and the air nozzle 220 is inclined at an angle of 135° to the support rod 210. There are seven support rods 210, and the seven support rods 210 are respectively arranged in seven spaced mounting holes 120. Each support rod 210 is perpendicular to the plane where the glass 10 is located, and forms an angle of 135° with the corresponding air nozzle 220.

[0040] In some other embodiments, by increasing the number of mounting holes 120 and the corresponding support rods 210 (and simultaneously increasing the number of air nozzles 220 ), the blowing device 30 can have a better cleaning effect.

[0041] Furthermore, the support rod 210 can freely rotate around its own central axis (360° rotation), and reciprocate in the vertical direction relative to the bracket 100, so as to adjust the wind outlet angle and wind outlet height of the air nozzle 220 in the horizontal direction, so as to form an adaptive purge area 31 and purge intensity according to different types of glass 10 or different work needs. The mounting hole 120 is a strip hole, and the extension direction of the mounting hole 120 is parallel to the first direction. The support rod 210 can reciprocate in the mounting hole 120 relative to the bracket 100 along the first direction. If the distance between two adjacent support rods 210 is small, the adjacent support rods 210 are staggered with each other in the first direction, which can avoid interference between multiple inclined air nozzles 220 when the support rods 210 rotate.

[0042] Furthermore, the gas supply mechanism 300 also includes a switch valve 320, a gas storage tank 330 and an air compressor 340. The air compressor 340 compresses the gas stored in the gas storage tank 330 into the ventilation pipe 214 of the support rod 210 through the gas transmission pipe 310. The switch valve 320 is arranged on the gas transmission pipe 310 to control the connection state between the gas storage tank 330 and the ventilation pipe 214.

[0043] In the automatic purge system provided by the present invention, the switch valve 320 and the switch unit 41 are independently arranged. When the switch valve 320 is opened and the switch unit 41 is opened, the gas stored in the gas storage tank 330 enters the ventilation pipe 214 through the air compressor 340, so that the purge device 30 starts to work. When one or both of the switch valve 330 and the switch unit 41 are closed, the gas is intercepted accordingly, that is, the purge device 30 stops working.

[0044] It can be understood that in some other embodiments, the switch valve 320 and the switch unit 41 can be the same device.

[0045] Furthermore, the purge device 30 further includes a suspension mechanism 400 and a drive mechanism 500, wherein the suspension mechanism 400 is used to suspend the bracket 100 above the conveying roller 22, so that the purge mechanism 200 can clean the glass 10 laid on the conveying roller 22 and conveyed by the conveying roller 22, and the drive mechanism 500 is connected to the suspension mechanism 400 to drive the suspension mechanism 400 to move in the first direction and the second direction respectively, so as to adjust the position of the bracket 100. The second direction is parallel to the plane where the glass 10 is located and perpendicular to the first direction.

[0046] Specifically, the suspension mechanism 400 includes a mounting portion 410 and a stop screw 420, one end of the stop screw 420 is passed through the bracket 100, and the other end is connected to the mounting portion 410, so that the mounting portion 410 can hang the bracket 100 through the stop screw 420, and when the stop screw 420 is rotated, the bracket 100 moves back and forth in the vertical direction to adjust the height of the bracket 100.

[0047] Specifically, the driving mechanism 500 includes a first driving assembly 510 and a second driving assembly 520. The first driving assembly 510 is drivingly connected to one end of the mounting portion 410 away from the attachment screw 420, thereby driving the mounting portion 410 to reciprocate along the first direction to adjust the position of the bracket 100 along the first direction. The second driving assembly 520 is drivingly connected to one end of the first driving assembly 510 away from the mounting portion 410, thereby driving the mounting portion 410 and the first driving assembly 510 to reciprocate along the second direction to adjust the position of the bracket 100 along the second direction.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
