Description

Technical Field

[0001] The utility model relates to the technical field of battery sheet production, and more particularly to a wind direction detection device in a wool-making yarn body. Background Art

[0002] Texturing is a critical step in the production of solar cells, directly impacting the cell's photoelectric conversion efficiency. The purpose of texturing is to remove mechanical damage from the silicon wafer surface, increase surface area, reduce surface reflectivity, remove impurities, and increase light absorption through light trapping.

[0003] During the cell texturing process, wind direction detection is crucial to ensuring uniformity and efficiency. Currently, to detect wind direction during the texturing process, a piece of paper is placed above the texturing trough, and the wind direction is determined by observing the paper's swing. However, the swing direction of the paper is not specified and is relatively arbitrary, resulting in inaccurate detection results.

[0004] Therefore, it is an urgent problem for those skilled in the art to develop a wind direction detection device inside a woolen yarn body with accurate detection results. Utility Model Content

[0005] In view of this, the utility model provides a wind direction detection device inside a woolen yarn body with accurate detection results.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wind direction detection device in a wool-making yarn body, comprising:

[0008] Mounting rack,

[0009] A swing rod, the top of which is hinged to the mounting frame; a windshield is provided on the surface of the swing rod, and the windshield is perpendicular to the wind direction;

[0010] The bottom of the swing rod is slidably connected to the base, and the swing rod swings along the wind direction.

[0011] The beneficial effect of adopting the above technical solution is that in the present invention, the wind direction can be judged by the swing direction of the pendulum rod, and the sliding connection between the pendulum rod and the base can limit the swing direction of the pendulum rod, making the swing direction of the pendulum rod more accurate.

[0012] Preferably, the detection device further comprises a detection box, and air holes are provided on both end surfaces of the detection box along the wind direction, and the mounting frame, the rocker arm and the base are all arranged inside the detection box.

[0013] Preferably, the top of the base is arc-shaped.

[0014] Preferably, a swing ball is provided at the bottom of the swing rod.

[0015] Preferably, a chute is provided on the top of the base, and the swinging ball is placed in the chute and swings in the chute. The swinging ball can slide accurately in the chute to ensure the accuracy of the detection result.

[0016] Preferably, the width of the chute is adapted to the diameter of the swing ball. The chute limits the swing ball so that it can only swing along the direction of wind flow, thereby improving the accuracy of the detection result.

[0017] Preferably, the slide groove is arc-shaped and matches the swing curve of the bottom of the swing rod.

[0018] Preferably, an indicator light is provided on the outside of the detection box, which makes it easier for staff to observe the wind direction.

[0019] Preferably, the swinging ball is a metal ball, and conductive sheets are respectively provided at both ends of the slide groove; the two conductive sheets are respectively connected to corresponding indicator lights through wires.

[0020] Preferably, a connecting plate is provided on the top of the detection box, which facilitates fixing the detection box above the texturing tank.

[0021] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a wind direction detection device in a wool-making yarn body, which has the following beneficial effects:

[0022] (1) The swing rod of the utility model swings with the wind direction and turns on the corresponding indicator light, making it convenient for staff to observe the wind direction;

[0023] (2) The swing ball slides in the chute to limit the swing direction of the pendulum, so that the pendulum swings only along the wind direction, thereby improving the accuracy of the measurement results. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The embodiment of the utility model discloses a wind direction detection device in a wool-making yarn body, comprising:

[0038] Mounting frame 1,

[0039] A swing rod 2, the top of which is hinged to the mounting frame 1; a windshield 3 is provided on the surface of the swing rod 2, and the windshield 3 is perpendicular to the wind direction;

[0040] The base 4, the bottom of the swing rod 2 is slidably connected to the base 4, and the swing rod 2 swings along the wind direction.

[0041] In order to further optimize the above technical solution, the detection device also includes a detection box 5, which has air holes 51 on both end surfaces along the wind direction. The mounting frame 1, the rocker arm 2 and the base 4 are all arranged inside the detection box 5.

[0042] In order to further optimize the above technical solution, the top of the base 4 is arc-shaped. The shape of the base 4 can adapt to the swing direction of the pendulum.

[0043] In order to further optimize the above technical solution, a swing ball 6 is provided at the bottom of the swing rod 2 .

[0044] To further optimize the above technical solution, a chute 41 is provided on the top of the base 4. The swing ball 6 is placed in the chute 41 and swings in the chute 41. The width of the chute 41 is slightly larger than the diameter of the swing ball 6. This not only ensures that the swing ball 6 swings in the chute 41, but also limits the swing ball 6 to prevent it from swinging in other directions.

[0045] In order to further optimize the above technical solution, the width of the sliding groove 41 is adapted to the diameter of the swing ball 6 .

[0046] In order to further optimize the above technical solution, the sliding groove 41 is arc-shaped and matches the swing curve of the bottom of the rocker 2.

[0047] In order to further optimize the above technical solution, an indicator light 52 is provided on the outside of the detection box 5. There are three indicator lights 52. When the power is connected, the middle indicator light is always on, which can indicate whether there is a problem with the line; when the swing ball 6 swings to the left and contacts the conductive sheet at the left end of the chute 41, the arrow indicator light on the left is on; when the swing ball 6 swings to the right and contacts the conductive sheet at the right end of the chute 41, the arrow indicator light on the right is on; when the arrow indicator lights on both sides are off and only the middle indicator light is on, it means that there is no wind at this time. When the battery cell is being velveted, it is necessary to ensure that the wind direction always remains in one direction. For example, when the direction needs to be kept to the left, the left indicator light shows green and the right indicator light shows red. It is also easy to judge whether the wind direction is correct or not by the color of the indicator light.

[0048] In order to further optimize the above technical solution, the swing ball 6 is a metal ball, and conductive sheets 7 are respectively provided at both ends of the slide groove 41; the two conductive sheets 7 are respectively connected to the corresponding indicator lights 52 through wires.

[0049] In order to further optimize the above technical solution, a connecting plate 53 is provided on the top of the detection box 5. The connecting plate 53 is connected to the top of the texturing tank by screws.
