[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0022] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.
[0023] According to an embodiment of the present invention, an automatic deviation correction oven nozzle is provided, comprising: a nozzle body 1, with an air outlet communicating with its inner cavity along its length at the top; a return air cavity 2 located at the air outlet inside the nozzle body 1, with air outlet slits 3 formed on both sides of the return air cavity 2 and the inner walls of both sides of the nozzle body 1; the air outlet slits 3 communicating with the air outlet for air outlet to support and dry the substrate 12; a plurality of return air holes 4 on the side of the return air cavity 2 facing the air outlet; a return air port 5 on at least one side of the nozzle body 1 along its length, the return air port 5 communicating with the return air cavity 2; and a wind speed adjustment mechanism, including a deviation correction detection element 6 and an opening adjustment component, the deviation correction detection element 6 being communicatively connected to the opening adjustment component; the opening adjustment component being located at the return air port 5 for adjusting the air outlet area of the return air port 5 to adjust the support pressure; and the deviation correction detection element 6 being located on the nozzle body 1 for detecting the deviation difference of the substrate 12 along the length of the nozzle body 1.
[0024] It should be noted that the inner cavity of the nozzle body 1 is connected to the external air intake device; the nozzle body 1 is arranged along the width direction of the substrate 12.
[0025] In this embodiment, the airflow from the nozzle body 1 passes through the air outlet slit 3 and the air outlet and blows upwards. This upward airflow pressure supports the substrate 12 passing above, simultaneously drying the substrate 12. During the drying process, a portion of the airflow flows back into the return air chamber 2 through the return air hole 4, and then exits through the return air outlet 5. The remaining airflow flows out from both sides of the substrate 12. The deviation difference of the substrate 12 along the length direction of the nozzle body 1 is detected by the deviation detection component 6. When the substrate 12 is detected to be moving away from the deviation adjustment component, it indicates that the airflow pressure P1 at the end of the nozzle body 1 with the opening adjustment component is greater than the airflow pressure P2 on the side away from the opening adjustment component. The deviation detection component 6 feeds back the detection result to the opening adjustment component, which controls the corresponding opening adjustment component to increase the airflow area of the return air outlet 5, thereby increasing the airflow discharged from the return air outlet 5 and reducing the airflow pressure at that position, making P1 equal to P2. This balances the pressure along the width direction below the substrate 12. This ensures that the substrate 12 remains in the center position. Conversely, when the substrate 12 is detected to move towards the side closer to the opening adjustment component, it indicates that the air pressure P1 at the end of the nozzle body 1 with the opening adjustment component is less than the air pressure P2 on the side away from the opening adjustment component. The correction detection component 6 feeds back the detection result to the opening adjustment component, and controls the corresponding opening adjustment component to reduce the air outlet area of the return air port 5, thereby reducing the airflow discharged from the return air port 5 and increasing the air pressure at that position, making P1 equal to P2. By adjusting the air outlet area of the return air port 5, the air pressure below the substrate 12 is adjusted, so that the pressure of the substrate 12 in the width direction is balanced to achieve correction, so that the substrate 12 remains in the center position during conveying. The correction detection component 6 and the opening adjustment component work together to achieve automated correction adjustment without manual adjustment, saving time and effort. Compared with the use of correction suspension rollers or adsorption rollers for adjustment, this automatic correction method is faster and easier to achieve quantitative adjustment, and can adapt to various process requirements.
[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, the opening adjustment component includes a sealing plate 7 and a first driving member 8; the sealing plate 7 is slidably connected to the side of the nozzle body 1, and the return air port 5 is located on the sliding path of the sealing plate 7; the sealing plate 7 is fitted to the side of the nozzle body 1 and is driven by the first driving member 8 to move towards or away from the return air port 5.
[0027] In this embodiment, by setting a sealing plate 7 on the side of the nozzle body 1, and driving the sealing plate 7 to move towards or away from the return air vent 5 by the first driving member 8, the sealing plate 7 moves to cover part of the air outlet area of the return air vent 5, thereby adjusting the air outlet area of the return air vent 5, thereby adjusting the pressure balance in the width direction of the substrate 12 to correct the deviation, and solving the problem of the substrate 12 deviating due to uneven air velocity in the air outlet slit 3 or uneven horizontality of the nozzle body 1.
[0028] Specifically, the first driving component 8 is a cylinder, a hydraulic cylinder, or a linear drive motor, etc.
[0029] In one embodiment, such as Figure 1 As shown, both the air outlet and the sealing plate 7 are rectangular, and the area of the sealing plate 7 is larger than the area of the air outlet; the sealing plate 7 is slidably connected to the side of the nozzle body 1 in the vertical direction.
[0030] It should be noted that the width direction of the air outlet is parallel to the width direction of the sealing plate 7, and the length direction of the air outlet is parallel to the vertical direction.
[0031] In this embodiment, both the air outlet and the sealing plate 7 are rectangular, and the sealing plate 7 is slidably connected to the side of the nozzle body 1 in the vertical direction, so that when the sealing plate 7 is adjusted to cover the air outlet, its coverage area can change evenly, thereby improving the adjustment accuracy.
[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, the side of the nozzle body 1 is provided with guide blocks 9 on both sides of the return air inlet 5. Each guide block 9 is provided with a sliding groove, and the two sides of the sealing plate 7 are slidably connected in the two sliding grooves respectively.
[0033] In this embodiment, guide blocks 9 are provided on both sides of the return air vent 5, so that the two sides of the sealing plate 7 are slidably connected in the groove of the guide block 9, thereby improving stability.
[0034] As a possible alternative implementation, it can also be, for example... Figures 5 to 8As shown, the side wall of the nozzle body 1 is provided with multiple first slide rails 25 at equal intervals around the outer periphery of the return air inlet 5. The first slide rails 25 are arranged in a direction that gradually moves away from the return air inlet 5 along the first rotation direction. The opening adjustment assembly includes: a rotary switch 21 with an opening coaxial with the return air inlet 5; multiple second slide rails are provided on the rotary switch 21 around the outer periphery of the opening corresponding to the first slide rails 25. The second slide rails are arranged in a direction that gradually moves away from the opening along the second rotation direction. The first rotation direction is opposite to the second rotation direction. An arc-shaped groove is provided on the rotary switch 21 on the outer side of the second slide rail, and the arc-shaped groove is concentric with the opening. Multiple blades 23 are located between the rotary switch 21 and the air inlet 5. Between the side walls of the nozzle body 1, there is a first state in which the axis around the opening is sequentially enclosed to form a closed structure, and a second state in which the axis around the opening is sequentially enclosed to form an open structure; the closed structure covers the air outlet; the number of blades 23 is the same as the number of first slides 25; the pusher 24 is sequentially inserted through the second slide, the blades 23 and the first slide 25, and the pusher 24 is slidably connected to the first slide 25 and the second slide; the guide 22 is inserted through the arc-shaped groove and connected to the side wall of the nozzle body 1; the guide 22 is slidably connected to the arc-shaped groove; the multiple blades 23 are driven by the rotary switch 21 to switch between the first state and the second state.
[0035] It should be noted that the blade 23 has a fan-shaped structure, and the sides of two adjacent blades 23 abut against each other.
[0036] In this embodiment, during installation, multiple blades 23 are first arranged to form a closed structure, which is placed between the rotary switch 21 and the side wall of the nozzle body 1. A pusher 24 is then sequentially inserted through the second slide rail, the blades 23, and the first slide rail 25. Simultaneously, a guide 22 passes through the arc-shaped groove to fix the rotary switch 21 to the nozzle body 1. Initially, the multiple blades 23 are in the first state, forming a closed structure covering the return air inlet 5 and the opening. Since the rotary switch 21 rotates in cooperation with the guide 22 via the arc-shaped groove, the rotation of the rotary switch 21 causes the second slide rail to push the pusher 24, moving the blades 23 along the trajectory of the first slide rail 25 towards the center away from the opening. The first slide rail 25, the second slide rail, and the pusher cooperate to ensure that the movement trajectory of the blades 23 is a rotation around the pusher 24 while moving towards the center away from the opening, thus forming an open structure in the central area. Switching to the second state, the size of the opening of the multiple blades 23 can be selected according to actual needs. Figures 5 to 7 As shown, the multiple blades 23 are in three states: fully closed, half-open, and fully open, thereby adjusting the air outlet area. Conversely, when the rotary switch 21 is rotated in the opposite direction, the multiple blades 23 can be adjusted to the closed state.
[0037] Specifically, it also includes a second driving component, which is used to drive the rotary switch 21 to rotate, thereby adjusting the air outlet area and realizing automated control.
[0038] Specifically, the second slide is designed in an arc shape to prevent jamming during adjustment.
[0039] Specifically, both the opening and the air outlet are circular.
[0040] As an alternative implementation, the opening adjustment component may include an electrically controlled valve, which adjusts the air outlet area.
[0041] In one embodiment, such as Figure 2 As shown, the correction detection component 6 is slidably connected to the nozzle body 1 along the length direction of the nozzle body 1.
[0042] In this embodiment, during the detection process, the detection end of the correction detection component 6 is aligned with the edge of the substrate 12. At the same time, the initial position of the substrate 12 is set by the program to detect the deviation difference of the substrate 12. Then, the deviation direction is determined based on the deviation difference and adjusted by the opening adjustment component until the substrate 12 returns to the initial position. The position of the correction detection component 6 can be adjusted by sliding along the length direction of the nozzle body 1 to adapt to substrates 12 with different widths and improve the applicability.
[0043] In one embodiment, such as Figure 2 As shown, the correction detection component 6 is connected to the nozzle body 1 via the support base 10. The support base 10 has a strip hole 11 along the length direction of the nozzle body 1, and the nozzle body 1 is bolted to the strip hole 11.
[0044] In this embodiment, the support base 10 is bolted to the nozzle body 1 through the strip hole 11. The support base 10 is fixed to the nozzle body 1 by the bolt passing through the strip hole 11. At the same time, the correction detection element 6 is set on the support base 10. In the initial position, the bolt can be located in the middle position of the strip hole 11. When adjustment is required, the bolt can be loosened, and the support base 10 can be moved to the appropriate position through the strip hole 11 and the bolt. Then, the bolt can be tightened again to fix it, so as to adapt to the substrate 12 of different widths to achieve correction, improve the applicability range, and facilitate adjustment.
[0045] In one embodiment, the correction detection element 6 is an ultrasonic sensor.
[0046] In this embodiment, the correction detection component 6 uses an ultrasonic sensor. During installation, the ultrasonic sensor can be aligned with the edge of the substrate 12 to improve the detection effect.
[0047] As an alternative implementation, the correction detection component 6 can also be a photoelectric sensor or a position sensor, etc., which can be selected according to actual needs.
[0048] In one embodiment, such as Figure 1 and Figure 2 As shown, the wind speed regulation mechanism is provided with one set.
[0049] In this embodiment, a set of wind speed adjustment mechanisms is provided. By adjusting the air outlet pressure on one side of the nozzle body 1 through the opening adjustment component of the set of wind speed adjustment mechanisms, the pressure balance adjustment under the substrate 12 can be achieved, thus correcting deviation and reducing costs.
[0050] As an alternative implementation, the wind speed adjustment mechanism can be provided in two sets, with the two sets of wind speed adjustment mechanisms respectively located at both ends of the nozzle body 1. Both sides of the nozzle body 1 are provided with return air inlets 5, and the two sets of wind speed adjustment mechanisms cooperate with each other to improve the adjustment effect.
[0051] The working principle of the automatic deviation correction oven nozzle provided in this embodiment is as follows: The nozzle body 1 is placed below the substrate 12, and airflow is blown upward through the air outlet to provide upward air pressure to support the substrate 12, while simultaneously drying the substrate 12. Before drying, the position of the support base 10 is adjusted so that the ultrasonic sensor is aligned with the edge of the substrate 12. During the drying process, the ultrasonic sensor detects the deviation difference of the substrate 12 in the length direction of the nozzle body 1 in real time. When the substrate 12 is detected to move away from the deviation adjustment component, it indicates that an opening is provided in the length direction of the nozzle body 1. When the air pressure P1 at one end of the adjustment component is greater than the air pressure P2 on the side away from the opening adjustment component, the ultrasonic sensor feeds back the detection result to the opening adjustment component. This controls the first driving component 8 to drive the sealing plate 7 to move away from the return air vent 5, reducing the obstruction area of the return air vent 5. This increases the air outlet area of the return air vent 5, resulting in more airflow and reducing the air pressure at that location. This makes P1 equal to P2, thus balancing the pressure along the width of the substrate 12 and keeping the substrate 12 in a centered position. Conversely, when the pressure P1 at one end of the adjustment component is greater than the air pressure P2 on the side away from the opening adjustment component, the ultrasonic sensor detects that the substrate 12 is moving away from the opening adjustment component. When the nozzle moves to the side, it indicates that the air pressure P1 at the end of the nozzle body 1 with the opening adjustment component is less than the air pressure P2 on the side away from the opening adjustment component. The ultrasonic sensor feeds back the detection result to the opening adjustment component, which controls the first driving component 8 to drive the sealing plate 7 to move closer to the return air port 5, increasing the blocking area of the return air port 5, reducing the air outlet area of the return air port 5, reducing the airflow discharged from the return air port 5, and thus increasing the air pressure at that position, making P1 equal to P2. By adjusting the air outlet area of the return air port 5, the air pressure below the substrate 12 is adjusted, making the substrate... The pressure balance in the width direction of the substrate 12 achieves correction, ensuring that the substrate 12 remains in the center position during conveying. The ultrasonic sensor and the opening adjustment component work together to achieve automated correction adjustment, eliminating the need for manual adjustment, saving time and effort. Compared with the use of correction suspension rollers or adsorption rollers for adjustment, this automatic correction method is more responsive and easier to achieve quantitative adjustment. It can adapt to various process requirements and solve the problem that the unstable airflow and tension inside the existing suspension drying oven structure can easily cause the substrate 12 to deviate inside the oven during suspension drying, affecting the drying quality of the substrate 12.
[0052] According to an embodiment of the present invention, another aspect provides a suspended drying oven, comprising: an oven body; a plurality of air nozzles, spaced apart within the oven body along the conveying direction of the substrate 12, for supporting and drying the substrate 12 by air outlets of the air nozzles; the air nozzles are automatic correction oven air nozzles as described in any embodiment of the first aspect.
[0053] In this embodiment, an automatically correcting oven nozzle is applied in a suspended oven to provide air pressure for supporting and drying the substrate 12. The suspended oven employs the automatically correcting oven nozzle of any embodiment of the first aspect. The specific structure of the automatically correcting oven nozzle is the same as that of the automatically correcting oven nozzle of any embodiment of the first aspect, ensuring that the suspended oven with the automatically correcting oven nozzle has at least the same technical effect as the aforementioned automatically correcting oven nozzle. The specific principle is the same as that of any embodiment of the first aspect, and will not be described in detail here.
[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
