Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a rapid drying device for an aluminum substrate used in production. Background Art

[0002] Aluminum substrate is a material commonly used in the electronics industry, mainly used to manufacture the heat dissipation system of products such as LED lighting and power electronic equipment. It is made of aluminum alloy material and has good thermal conductivity, corrosion resistance and light weight. The structure of aluminum substrate usually consists of three layers: aluminum base layer, thermal conductive layer and circuit layer. Drying equipment is needed to dry the aluminum plate after glue coating during processing.

[0003] Aluminum substrates are usually dried in a tunnel-type hot air drying box during processing. Most existing hot air drying boxes have air holes on the top or side walls of the box to allow hot air to blow toward the aluminum plate from above or from the side. However, the position of the air holes is often fixed, resulting in a fixed position for the hot air to directly blow toward the aluminum plate. This can easily lead to uneven distribution of the hot air flow, which causes the hot air flow to be concentrated in a specific area, resulting in excessive wind speed in some areas and insufficient wind speed in other areas. The temperature in the hot air concentrated area is too high, which exceeds the tolerance range of the aluminum substrate or coating, resulting in material aging or performance degradation, affecting product quality. In addition, the fixed position of the air holes may also result in the hot air being unable to effectively cover the entire substrate, requiring the temperature to be increased or the drying stroke to be extended, increasing energy consumption. Summary of the invention

[0004] The present invention provides a rapid drying device for aluminum substrates for production, aiming to solve the problem in the related art that the direct blowing position of hot air on the aluminum plate is fixed, which easily leads to uneven distribution of hot air flow, causing the hot air flow to be concentrated in a specific area and unable to effectively cover the entire substrate.

A turbine is rotatably assembled on the central shaft, and a connecting rod is fixedly installed on one side of the turbine away from the connecting pipe. The end of the connecting rod extends into the air distribution cylinder and is fixed thereto.

[0011] Preferably, the transmission component includes a reciprocating lead screw and a slider. The reciprocating lead screw is coaxially fixed in the middle of the central shaft, and the slider is arranged on the reciprocating lead screw and can move along the thread groove on the reciprocating lead screw, and the slider is fixed to the air distribution cylinder.

[0012] Preferably, the plurality of air distribution pipes are divided into multiple groups, and the multiple groups of air distribution pipes are equidistantly distributed along the axial direction of the air distribution cylinder. And the multiple air distribution pipes in each group are annularly and evenly distributed along the circumferential direction of the air distribution cylinder. The air distribution pipe is spherical in shape, and through holes are formed inside it to allow hot air to pass through. And the air distribution pipe is magnetically connected to the air distribution cylinder. The air distribution pipe can rotate in the axial direction of the air distribution cylinder, and the suction force between the air distribution pipe and the air distribution cylinder is greater than the thrust of the hot air.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0025] As Figures 1 to 7 shown, the rapid drying device for aluminum substrates used in production of the present invention includes a box body 10, a hot air assembly 20, a wind guiding member 30, a air distribution mechanism 40, a wind driving mechanism 50, a transmission assembly 60, a connection assembly 70, and a lifting mechanism 80. The box body 10 has multiple sections and is spliced together along its length direction. The hot air assembly 20 is arranged above the wind guiding member 30 and is used to convey hot air into the wind guiding member 30. The wind guiding member 30 is arranged at the end side of the air distribution mechanism 40 and conveys the hot air to the air distribution mechanism 40 to distribute air inside the box body 10. The wind driving mechanism 50 is arranged between the wind guiding member 30 and the air distribution mechanism 40 and can drive the air distribution mechanism 40 to rotate and distribute air under the drive of hot air, and the rotating air distribution mechanism 40 is axially moved to distribute air by the transmission assembly 60. The connection assembly 70 connects between two wind guiding members 30 so that the lifting mechanism 80 can drive the two wind guiding members 30 to lift synchronously, thereby adjusting the air distribution height.

[0026] Referring to Figures 1 - 3 , an air cavity 11 and a drying cavity 12 are arranged inside the box body 10. The air cavity 11 is located above the drying cavity 12, and the air cavity 11 is communicated with the drying cavity 12 through a vertical pipe 13. Material ports 14 communicated with the drying cavity 12 are opened at both ends of the box body 10 to facilitate the material plate to enter and exit the drying cavity 12 inside the box body 10.

[0027] Referring to Figure 3 and Figure 4 , the hot air assembly 20 includes an air inlet pipe 21 and a heating plate 22. The air inlet pipe 21 is inserted and connected to the top of the box body 10 to communicate with the air cavity 11 and is used to supply air into the air cavity 11. The heating plate 22 is arranged inside the air cavity 11 and is used to heat the air inside the air cavity 11.

[0028] Referring to Figure 2 , Figure 5 and Figure 6 , the wind guiding member 30 includes a wind guiding cylinder 31, a wind guiding pipe 32, and a connecting pipe 33. The wind guiding cylinder 31 is horizontally arranged inside the drying cavity 12 of the box body 10, and the axial direction of the wind guiding cylinder 31 is perpendicular to the conveying direction of the material plate. The wind guiding pipe 32 is vertically inserted into the top of the wind guiding cylinder 31, and its top end is connected to the vertical pipe 13, and can guide the hot air in the air cavity 11 into the inside of the wind guiding cylinder 31. The connecting pipe 33 is inserted into the inner side of the wind guiding cylinder 31 (i.e., the side close to the middle of the box body 10) and is coaxially arranged with the wind guiding cylinder 31 to guide the hot air in the wind guiding cylinder 31 to flow towards the middle of the box body 10.

[0029] Referring to Figure 4 andFigure 6 , the air distribution mechanism 40 includes an air distribution cylinder 41 and air distribution pipes 42. The air distribution cylinder 41 is sleeved outside the connecting pipe 33 and can rotate and axially slide relative to the connecting pipe 33, so that the hot air led out by the connecting pipe 33 can enter the inside of the air distribution cylinder 41. The air distribution pipes 42 are arranged on the cylinder wall of the air distribution cylinder 41, and there are multiple air distribution pipes 42 and they are divided into multiple groups. The multiple groups of air distribution pipes 42 are equidistantly distributed along the axial direction of the air distribution cylinder 41, and each group of multiple air distribution pipes 42 are circumferentially and annularly evenly distributed along the circumference of the air distribution cylinder 41, and can guide the hot air in the air distribution cylinder 41 to blow towards the surface of the material plate. The air distribution pipes 42 are spherical in shape, and through holes are provided inside them to allow hot air to pass through, and the air distribution pipes 42 are magnetically connected to the air distribution cylinder 41. The air distribution pipes 42 can rotate in the axial direction of the air distribution cylinder 41, and the suction force between the air distribution pipes 42 and the air distribution cylinder 41 is greater than the thrust of the hot air, so that the air distribution pipes 42 will not rotate under the push of the hot air; during equipment debugging before drying, the staff can dial the air distribution pipes 42 to rotate to make the through holes inclined, and then guide the hot air to blow obliquely towards the material plate. When drying a thicker material plate, it can better cover the side wall of the material plate, increase the direct coverage area of the hot air, and improve the drying effect.

[0030] Reference Figure 4 And Figure 7 , the air driving mechanism 50 includes a central shaft 51 and a turbine 52. The central shaft 51 is coaxially arranged inside the air distribution cylinder 41, and its end penetrates through the connecting pipe 33 and is fixedly installed in the air guiding cylinder 31. The turbine 52 is rotatably assembled on the central shaft 51 and is located inside the connecting pipe 33, and can rotate on the central shaft 51 under the push of the hot air blown out by the connecting pipe 33. A connecting rod 521 in the shape of an L is fixedly connected to the side of the turbine 52 away from the connecting pipe 33. The end of the connecting rod 521 away from the turbine 52 extends into the air distribution cylinder 41 and is fixed to it, so that when the turbine 52 rotates, it can drive the air distribution cylinder 41 to rotate synchronously, and make the air distribution pipes 42 rotate and blow air, increasing the uniformity of air distribution.

[0031] Reference Figure 4 And Figure 7 , the transmission component 60 includes a reciprocating lead screw 61 and a slider 62. The reciprocating lead screw 61 is coaxially fixed in the middle of the central shaft 51. The slider 62 is arranged on the reciprocating lead screw 61 and can move along the thread groove on the reciprocating lead screw 61, and the slider 62 is fixedly installed inside the air distribution cylinder 41. When the air distribution cylinder 41 rotates, it drives the slider 62 to rotate on the reciprocating lead screw 61. Under the guidance of the reciprocating lead screw 61, the slider 62 and the air distribution cylinder 41 perform axial reciprocating motion, and then make the air distribution pipes 42 move and blow air, improving the uniformity of air distribution and the drying effect.

[0032] Reference Figure 4 And Figure 5, the connecting component 70 includes an arc-shaped plate 71, a sliding rod 72 and a sleeve 73. The arc-shaped plate 71 is arranged above the air distribution tube 41 and can block the hot air, so that the hot air in the air distribution tube 41 can only be discharged downward. The sliding rod 72 is horizontally fixed at the end of the arc-shaped plate 71. The sleeve 73 is fixedly installed on the side wall of the air guide pipe 32 and is coaxially arranged with the air guide cylinder 31. The sliding rod 72 is slidably assembled inside the sleeve 73, so that the arc-shaped plate 71 can move between the two air guide pipes 32 of the air guiding member 30 and connect the two air guide pipes 32, so that when one air guide pipe 32 moves up and down, it can drive the other to move up and down synchronously. An annular portion 711 adapted to the air distribution pipe 42 is provided on the arc-shaped plate 71, and one end of the air distribution pipe 42 away from the air distribution tube 41 extends into the annular portion 711. The annular portion 711 further improves the shielding effect of the arc-shaped plate 71 on the air distribution pipe 42 and enables the air distribution pipe 42 to push the arc-shaped plate 71 to move. While the arc-shaped plate 71 restricts the air distribution tube 41 from discharging upward, it will not cause obstruction to the movement of the air distribution tube 41.

[0033] Reference Figure 4 , the lifting mechanism 80 includes a telescopic tube 81 and an electric telescopic rod 82. The telescopic tube 81 is located between the vertical tube 13 and the air guide pipe 32, and its two ends are respectively fixed to the vertical tube 13 and the air guide pipe 32. The electric telescopic rod 82 is located on one side of the telescopic tube 81, and the electric telescopic rod 82 is fixedly installed on the vertical tube 13. The telescopic end of the electric telescopic rod 82 is arranged on the air guide pipe 32, and the air guide pipe 32 can be pushed to move up and down by the electric telescopic rod 82, so that the telescopic tube 81 can be telescoped, and then the height of the air distribution tube 41 can be adjusted, and the air distribution height can be adjusted according to the drying progress of the material plate in each box body 10, and then the drying effect can be improved.

[0034] Working principle: The material plate enters the drying chamber 12 from the material inlet 14 at one end of the box body 10 and passes out from the material inlet 14 at the other end, and successively passes through the inside of multiple box bodies 10. The air inlet pipe 21 continuously supplies air into the air chamber 11, and the heating plate 22 heats the air in the air chamber 11 to form hot air. The hot air enters the air guide pipe 32 from the vertical pipe 13, and after being guided by the air guide cylinder 31, it is discharged into the air distribution tube 41 through the connecting pipe 33, and then is blown to the material plate through the air distribution pipe 42 on the air distribution tube 41 to dry it; When the hot air passes through the inside of the connecting pipe 33, it will push the turbine 52 to rotate around the central axis 51. The turbine 52 drives the air distribution tube 41 to rotate, so that the air distribution pipe 42 rotates and blows air, so that the hot air can evenly cover the surface of the material plate. While the air distribution tube 41 rotates, it drives the slider 62 to rotate, and the slider 62 moves along the thread groove on the reciprocating lead screw 61, so that the slider 62 drives the air distribution tube 41 to perform an axial reciprocating motion, so that the air distribution pipe 42 can move horizontally while rotating and blowing air, and the hot air can effectively and completely cover the surface of the material plate to be dried; When the air distribution duct 41 moves axially, the arc-shaped plate 71 is pushed by the air distribution pipe 42 to move synchronously. The arc-shaped plate 71 blocks the upward air outlet of the air distribution duct 41, ensuring that the hot air can only be discharged downward, increasing the air pressure of the hot air discharge. The guide air duct 32 is driven by the electric telescopic rod 82 to lift and lower, so that the telescopic pipe 81 expands and contracts, and then the height of the air distribution duct 41 is adjusted, and the distance between the air distribution pipe 42 and the material plate is adjusted, facilitating the control of the drying intensity in each box body 10.

[0035] Beneficial effects: Through the mutual cooperation of the central shaft 51 and the turbine 52, when the hot air enters the connecting pipe 33, it can drive the air distribution duct 41 to rotate, and then the air distribution pipe 42 rotates to blow air, increasing the coverage area of the hot air in the length direction of the material plate. And with the cooperation of the reciprocating lead screw 61 and the slider 62, the rotating air distribution duct 41 moves axially back and forth, and then the air distribution pipe 42 moves horizontally to blow air, increasing the coverage area of the hot air in the width direction of the material plate, effectively improving the uniformity of the distribution of the hot air flow in the drying chamber 12, reducing the air distribution dead angle, and then avoiding the phenomenon of over-concentration of the hot air flow, enabling the material plate to be evenly heated, reducing the probability of over-drying, improving the overall drying rate of the material plate, reducing the drying stroke of the material plate, and improving the drying quality; by blocking the upper part of the air distribution duct 41 with the arc-shaped plate 71, the hot air can only be blown downward, increasing the air pressure of the hot air and improving the air distribution intensity; by adjusting the height of the air distribution duct 41 through the telescopic pipe 81 and the electric telescopic rod 82, the air distribution intensity can be adjusted according to the drying progress of the material plate, and then the drying quality is improved.
