Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, and more specifically, to an internal airflow circulation guide mechanism for an aging machine. Background Technology

[0002] An aging chamber, also known as an aging test chamber, is a device that simulates various harsh environmental conditions. It is used to conduct reliability tests and quality assessments on industrial products (mainly electronics, electrical appliances, materials, automotive parts, etc.). The airflow circulation guide mechanism is a key component of the aging chamber, used to circulate the airflow inside the aging chamber.

[0003] The existing guidance mechanisms have the following problems during use: Firstly, the instruments waiting for aging tests are evenly placed on the support inside the aging machine. When the instruments are large, they generate a lot of heat in specific locations because they need to operate. Since the airflow is generally evenly distributed in the aging machine, it is not easy to remove the heat accumulated in specific parts of the instruments, forming local hot spots. This leads to inconsistent test conditions and screening failure. Secondly, after the airflow leaves the guide mechanism, it usually enters the aging machine through one or more linearly distributed outlets on it and slowly diffuses into the interior of the aging machine. The diffusion efficiency is low. In view of this, we propose an internal airflow circulation guide mechanism for the aging machine. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing an internal airflow circulation guide mechanism for an aging machine to solve the problems of existing solutions.

[0005] To achieve the above objectives, this utility model provides an internal airflow circulation guiding mechanism for an aging machine, including a device box. A fan is fixedly connected inside the device box. The device box has two mounting holes, which are symmetrically arranged at the center of both sides of the device box. A first perforated plate is fixedly connected inside the mounting holes. One side of the first perforated plate is provided with a flow guiding mechanism for dispersing airflow, and the other side of the flow guiding mechanism is provided with multiple ejection mechanisms for adjusting the direction and position of airflow. The other side of the first perforated plate is provided with a return flow mechanism for returning airflow to the device box. The flow guiding mechanism includes a first fixed shell, one side of which is fixedly connected to the outer ring of the device box. A first air duct is fixedly connected to the surface of the first fixed shell. A first flow guiding pipe is fixedly connected to the end of the first air duct away from the device box. A second flow guiding pipe is fixedly connected to one end of the first flow guiding pipe. Two sets of third flow guiding pipes are fixedly connected to the second flow guiding pipe. The two sets of third flow guiding pipes are symmetrically arranged at the top and bottom of the second flow guiding pipe. The ejection mechanism is connected to the third flow guiding pipes.

[0006] The beneficial effects of this utility model are: 1) In the internal airflow circulation guide mechanism of the aging machine, the second air supply pipe is pulled through the nozzle, the second air supply pipe and the sliding slider along the slide groove, which drives the hose and nozzle to move. The first and second rotating shafts are rotated, which drives the fourth air supply pipe and nozzle to rotate, changing the nozzle orientation. This allows the nozzle outlet to be accurately directed towards the high heat-generating part of the instrument, so as to focus on heat dissipation of the high heat-generating part of the instrument, prevent the generation of local hot spots, maintain the same test conditions, and reduce the probability of screening failure.

[0007] 2) In the internal airflow circulation guiding mechanism of the aging machine, the fan is rotated through the second guide pipe, the third guide pipe and the nozzle to generate negative pressure. The airflow flows through the first guide pipe, the second guide pipe and multiple third guide pipes to expand the distribution of the airflow. Finally, it is ejected from each nozzle. The airflow quickly diffuses to various positions in the aging machine, so that the airflow can fill the interior of the aging machine more quickly and improve the diffusion efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows: As a further improvement to this technical solution, multiple ejection mechanisms have the same structure. Each ejection mechanism includes a first air supply pipe, one end of which is fixedly connected to the third guide pipe. One end of the first air supply pipe is fixedly connected to a corrugated pipe, and one end of the corrugated pipe is fixedly connected to a second air supply pipe. An air jet component is provided on the surface of the second air supply pipe.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the number of jet components can be changed according to actual production needs, and is at least one. Through the corrugated pipe, the second air supply pipe is pulled, and the corrugated pipe is extended or shortened to change the position of the first air supply pipe to adjust the airflow ejection position. Each third guide pipe is provided with the same number of first air supply pipes, and the number of first air supply pipes is arranged in a linear array. The number of first air supply pipes is adapted to the number of support layers inside the aging machine.

[0010] As a further improvement to this technical solution, a solenoid valve is fixedly connected to one end of the second gas supply pipe. The solenoid valve is fixedly connected to two first connecting rods. The two first connecting rods are symmetrically arranged on both sides of the solenoid valve. A second connecting rod is abutted against one side of the first connecting rod. Multiple first bolts are threaded to the other side of the first connecting rod. One end of the first bolt passes through the first connecting rod and extends into the second connecting rod. One end of the second connecting rod is fixedly connected to the third guide pipe.

[0011] The beneficial effect of adopting the above-mentioned further solution is that after adjusting the position of the second gas supply pipe through the first connecting rod and the second connecting rod, the electromagnetic valve and the first connecting rod move accordingly. Tightening the first bolt can fix the first connecting rod and the second connecting rod together, thereby fixing the position of the second gas supply pipe and ensuring the structural stability of the second gas supply pipe.

[0012] As a further improvement to this technical solution, the jet component includes a third air supply pipe, one end of which is fixedly connected to the second air supply pipe, one end of which is fixedly connected to a hose, one end of which is fixedly connected to a fourth air supply pipe, and one end of which is fixedly connected to a nozzle.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that the gas that enters the second gas pipe through the third gas pipe, the hose and the fourth gas pipe leaves the second gas pipe from the third gas pipe, enters the fourth gas pipe, and is finally sprayed out from the nozzle into the aging machine. Changing the position of the nozzle can change the position and direction of the airflow.

[0014] As a further improvement to this technical solution, the jet component also includes a first rotating shaft, one end of which is fixedly connected to the fourth air supply pipe, and the other end of which is rotatably connected to a first connecting block. A second rotating shaft is fixedly connected to the top of the first connecting block, and one end of the second rotating shaft is rotatably connected to a second connecting block. Locking nuts are threadedly connected to the connection points between the first rotating shaft and the first connecting block, and between the second rotating shaft and the second connecting block.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, by rotating the first rotating shaft and the second rotating shaft, the first rotating shaft drives the fourth gas supply pipe and the nozzle to rotate, and then tightening the locking nut on the first rotating shaft, the nozzle angle can be changed in the vertical direction. By rotating the second rotating shaft, the first connecting block, the fourth gas supply pipe and the nozzle can be driven to rotate in the horizontal direction, and then tightening the locking nut on the second rotating shaft, the nozzle angle can be changed in the horizontal direction.

[0016] As a further improvement to this technical solution, the jet component also includes a fixing plate. One side of the fixing plate is fixedly connected to the second air supply pipe, and the other side of the fixing plate is provided with a sliding groove. A slider is slidably connected to the sliding groove. A second bolt is threadedly connected to the top of the fixing plate. One end of the second bolt passes through the fixing plate and abuts against the surface of the slider. An installation rod is fixedly connected to one side of the slider, and one end of the installation rod is fixedly connected to the top of the second connecting block.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by using the fixed plate and the slider, sliding the slider along the slide groove drives the mounting rod to move, and then tightening the second bolt can drive the nozzle to move, so as to change the position of the nozzle more flexibly, thereby changing the angle and position of the airflow when it is ejected from the nozzle.

[0018] As a further improvement to this technical solution, the reflux mechanism includes a second fixed shell, one side of which is fixedly connected to the outer ring of the other side of the equipment box, and a second air duct is fixedly connected to the surface of the second fixed shell. One side of the second air duct is fixedly connected to a plurality of vent holes that communicate with the inner cavity of the aging machine.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the second air duct is buried in the box wall of the aging machine, and the multiple sets of the above-mentioned vent holes are distributed in a linear array. After the airflow is ejected from multiple nozzles through the second air duct and the vent holes, it flows into the aging machine. The airflow inside the aging machine passes through the vent holes and enters the second air duct, and continues to flow along the second air duct, flowing through the second fixed shell and the first perforated plate, and returning to the equipment box, so as to realize the circulation process of the airflow inside the aging machine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, this embodiment provides an internal airflow circulation guiding mechanism for an aging machine, including a device box 1. The device box 1 is installed on the top of the aging machine by means of bonding, screws, or welding. A fan 2 is fixedly connected inside the device box 1. The fan 2 is a GXF-4A model. The device box 1 has two mounting holes 3, which are symmetrically arranged at the center of both sides of the device box 1. A first perforated plate 4 is fixedly connected inside the mounting holes 3. The first perforated plate 4 plays a role in equalizing the airflow, making the airflow more uniform after passing through the device box 1. One side of one of the first perforated plates 4 is provided with a flow guiding mechanism 6 for dispersing the airflow. One side of the flow guiding mechanism 6 is provided with multiple ejection mechanisms 7 for adjusting the direction and position of the airflow. The other side of the first perforated plate 4 is provided with a return mechanism 8 for returning the airflow to the device box 1. The airflow guiding mechanism 6 includes a first fixed housing 61, one side of which is fixedly connected to the outer ring of the equipment box 1. A first air duct 62 is fixedly connected to the surface of the first fixed housing 61. A second perforated plate 63 is fixedly connected to the inner wall of the first air duct 62, which also serves to equalize the airflow and make the airflow more uniform. A first guide pipe 64 is fixedly connected to the end of the first air duct 62 away from the equipment box 1. Both the first air duct 62 and the first guide pipe 64 are embedded in the wall of the aging machine. A second guide pipe 64 is fixedly connected to one end of the first guide pipe 64. The second guide pipe 65 is fixedly connected to two sets of third guide pipes 66. Each set of third guide pipes 66 has multiple third guide pipes 66 arranged in a linear array. The surfaces of the second guide pipe 65 and the third guide pipes 66 are in contact with the inner wall of the aging machine and are fixedly installed on the aging machine by means of bonding and clamps, so that the structure of the second guide pipe 65 and the third guide pipe 66 remains stable. The two sets of third guide pipes 66 are symmetrically arranged at the top and bottom of the second guide pipe 65. The spraying mechanism 7 is connected to the third guide pipes 66.

[0025] Furthermore, the multiple ejection mechanisms 7 have the same structure. Each ejection mechanism 7 includes a first air supply pipe 71, one end of which is fixedly connected to the third guide pipe 66. The first air supply pipe 71 is also fixedly connected to a corrugated pipe 72 at one end, which has a certain degree of elasticity. The second air supply pipe 73 is fixedly connected to one end of the corrugated pipe 72. The surface of the second air supply pipe 73 is provided with an air jet 74. The number of air jets 74 can be changed according to actual production needs, but there is at least one. By pulling the second air supply pipe 73 through the corrugated pipe 72, the corrugated pipe 72 can be extended or shortened to change the position of the first air supply pipe 71, thereby adjusting the ejection position of the airflow. Each third guide pipe 66 is provided with the same number of first air supply pipes 71, which are arranged in a linear array. The number of first air supply pipes 71 is adapted to the number of support layers inside the aging machine.

[0026] Furthermore, a solenoid valve 75 is fixedly connected to one end of the second gas supply pipe 73. The solenoid valve 75 is fixedly connected to two first connecting rods 76, which are symmetrically arranged on both sides of the solenoid valve 75. The first connecting rods 76 are installed on the solenoid valve 75 by means of adhesive bonding to avoid damage to the solenoid valve 75. The solenoid valve 75 is a BOV type. One side of the first connecting rod 76 abuts against a second connecting rod 77, and the other side of the first connecting rod 76 is threaded with multiple first bolts 78. One end of the first bolt 78 passes through the first connecting rod 76 and extends into the second connecting rod 77. One end of the second connecting rod 77 is fixedly connected to the third guide pipe 66. After adjusting the position of the second gas supply pipe 73 through the first connecting rod 76 and the second connecting rod 77, the solenoid valve 75 and the first connecting rod 76 move accordingly. Tightening the first bolts 78 can fix the first connecting rod 76 and the second connecting rod 77 together, thereby fixing the position of the second gas supply pipe 73 and ensuring the structural stability of the second gas supply pipe 73.

[0027] Furthermore, the jet component 74 includes a third air supply pipe 742, one end of which is fixedly connected to the second air supply pipe 73, and the other end of which is fixedly connected to a flexible hose 743. The flexible hose 743 has a certain degree of flexibility, and the other end of the flexible hose 743 is fixedly connected to a fourth air supply pipe 744. The other end of the fourth air supply pipe 744 is fixedly connected to a nozzle 745. The gas that enters the second air supply pipe 73 through the third air supply pipe 742, the flexible hose 743, and the fourth air supply pipe 744 leaves the second air supply pipe 73 through the third air supply pipe 742, enters the fourth air supply pipe 744, and is finally ejected from the nozzle 745 into the aging machine. Changing the position of the nozzle 745 can change the position and direction of the airflow.

[0028] Furthermore, the jet component 74 also includes a first rotating shaft 741, one end of which is fixedly connected to the fourth air supply pipe 744, and the other end of which is rotatably connected to a first connecting block 746. A second rotating shaft 747 is fixedly connected to the top of the first connecting block 746, and one end of the second rotating shaft 747 is rotatably connected to a second connecting block 748. Both the first connecting block 746 and the second connecting block 748 are provided with scale lines, and both the first rotating shaft 741 and the second rotating shaft 747 are marked with arrows pointing to the scale lines to determine the rotation angle of the first rotating shaft 741 and the first connecting block 747. Both the connection points of the first shaft 746 and the second shaft 747 with the second connecting block 748 are threaded with locking nuts 749. By rotating the first shaft 741 and the second shaft 747, the first shaft 741 is rotated, which drives the fourth air supply pipe 744 and the nozzle 745 to rotate. Then, by tightening the locking nut 749 on the first shaft 741, the angle of the nozzle 745 can be changed in the vertical direction. By rotating the second shaft 747, the first connecting block 746, the fourth air supply pipe 744 and the nozzle 745 are rotated in the horizontal direction. Then, by tightening the locking nut 749 on the second shaft 747, the angle of the nozzle 745 can be changed in the horizontal direction.

[0029] Furthermore, the jet component 74 also includes a fixing plate 7410. One side of the fixing plate 7410 is fixedly connected to the second air supply pipe 73, and the other side of the fixing plate 7410 is provided with a sliding groove 7411. A slider 7412 is slidably connected to the sliding groove 7411. A second bolt 7414 is threadedly connected to the top of the fixing plate 7410. One end of the second bolt 7414 passes through the fixing plate 7410 and abuts against the surface of the slider 7412. An mounting rod 7413 is fixedly connected to one side of the slider 7412. One end of the mounting rod 7413 is fixedly connected to the top of the second connecting block 748. By sliding the slider 7412 along the sliding groove 7411 through the fixing plate 7410 and the slider 7412, the mounting rod 7413 is moved. Then, by tightening the second bolt 7414, the nozzle 745 can be moved, and the position of the nozzle 745 can be changed more flexibly to change the angle and position of the airflow when it is ejected from the nozzle 745.

[0030] Furthermore, the reflux mechanism 8 includes a second fixed shell 81. One side of the second fixed shell 81 is fixedly connected to the outer ring of the other side of the equipment box 1. A second air duct 82 is fixedly connected to the surface of the second fixed shell 81. One side of the second air duct 82 is fixedly connected to a plurality of vent holes 83 that communicate with the inner cavity of the aging machine. The second air duct 82 is concealed in the wall of the aging machine. The plurality of vent holes 83 are arranged in a linear array. After the airflow is ejected from the plurality of nozzles 745 through the second air duct 82 and the vent holes 83, it flows into the aging machine. The airflow inside the aging machine passes through the vent holes 83 and enters the second air duct 82, and continues to flow along the second air duct 82, flowing through the second fixed shell 81 and the first perforated plate 4, and returning to the equipment box 1 to realize the circulation process of the airflow inside the aging machine.

[0031] In summary, the working principle of this solution is as follows: When aging a batch of large-volume instruments in an aging machine, the position and orientation of the nozzle 745 need to be adjusted according to the different high-heat areas of the instruments, so that the outlet of the nozzle 745 is aligned with the high-heat area of ​​the instrument. The method is as follows: Each second air supply pipe 73 is distributed in different layers of the internal support of the aging machine. Each second air supply pipe 73 corresponds to an instrument to be aged. Loosen the first bolt 78, pull the second air supply pipe 73, and the corrugated pipe 72 will extend or shorten. Then tighten the first bolt 78 to initially change the position of the first air supply pipe 71 and the nozzle 745. Next, slide the slider 7412 along the slide groove 7411 to move the mounting rod 7413, which will move the hose 743 and the nozzle 745. Then tighten the second bolt 7414 to change the position of the nozzle 745 more flexibly. When tightening the first bolt 78 and the second bolt 7414, pay attention to the position of the first bolt 78 and the second bolt 7414 so that the same adjustment can be made to the other second air supply pipes 73 and the nozzles 745. Next, observe the scale line on the first connecting block 746, rotate the first rotating shaft 741 to drive the fourth air supply pipe 744 and nozzle 745 to rotate, and then tighten the locking nut 749 on the first rotating shaft 741. Record the position of the scale line pointed to by the arrow at this time to change the angle of the nozzle 745 in the vertical direction. Next, observe the scale line on the second connecting block 748, rotate the second rotating shaft 747 to drive the first connecting block 746, the fourth air supply pipe 744 and nozzle 745 to rotate in the horizontal direction, and then tighten the locking nut 749 on the second rotating shaft 747. Similarly, record the position of the scale line pointed to by the arrow at this time to change the angle of the nozzle 745 in the horizontal direction. According to the scale line data corresponding to the first rotating shaft 741 (vertical angle) and the second rotating shaft 747 (horizontal angle), the rotation angles of the other first rotating shaft 741 and second rotating shaft 747 need to be adjusted. In this way, the outlet of the nozzle 745 can be accurately directed towards the high heat-generating part of the instrument to focus on heat dissipation of the high heat-generating part of the instrument. The specific airflow circulation process is as follows: The fan 2 rotates, generating negative pressure. The airflow passes through the first perforated plate 4 and enters the first fixed housing 61. It then flows along the first air duct 62, passing through the first guide pipe 64, the second guide pipe 65, and multiple third guide pipes 66, expanding the airflow distribution. The airflow leaves the third guide pipes 66 and enters the first air delivery pipe 71 and the corrugated pipe 72. At this time, the solenoid valve 75 is not activated. To ensure the airflow fills the first air delivery pipe 71 and the corrugated pipe 72, and to ensure the airflow is then evenly ejected from the nozzle 745, the solenoid valve 75 is opened after a set time has elapsed. The airflow continues to flow in each bellows 72, passing through the second air supply pipe 73, the third air supply pipe 742 and the hose 743 into the fourth air supply pipe 744, and finally spraying out from the nozzle 745. This not only concentrates heat dissipation on the high-heat parts of the instrument, but also allows the airflow to quickly diffuse to various positions in the aging machine, so that the airflow can fill the interior of the aging machine more quickly. Then, it passes through the vent 83 into the second air duct 82 and continues to flow along the second air duct 82, passing through the second fixed shell 81 and the first perforated plate 4, and returning to the equipment box 1, so as to realize the circulation process of the airflow inside the aging machine.
