Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, specifically a conveying mechanism to prevent false alarms triggered by hollowed-out materials. Background Technology
[0002] In industrial production, perforated materials (such as mesh metal plates, plastic mesh trays, and perforated PCB substrates) are prone to false alarms due to the presence of holes or gaps when passing through the detection devices of the conveying mechanism (such as photoelectric sensors, metal detectors, and foreign object detectors) because of light transmission, magnetic transmission, or signal interruption, which affects production efficiency.
[0003] To address the aforementioned issues, we propose a conveying mechanism that prevents false alarms triggered by hollowed-out materials. Utility Model Content
[0004] To address the problems in the background art, this utility model provides a conveying mechanism to prevent false alarms triggered by hollowed-out materials.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A conveying mechanism for preventing false alarms triggered by hollowed-out materials includes a mounting base. Conveyor belts are correspondingly arranged on both sides of the inner cavity of the mounting base. The two sets of conveyor belts are on the same horizontal plane. The left end of each set of conveyor belts is driven by a drive wheel, and the right end of each set of conveyor belts is driven by a driven wheel. The two sets of drive wheels are coaxially connected through a connecting shaft, and one end of the connecting shaft is connected to a drive motor.
[0007] A false alarm prevention detection component includes a photoelectric sensor, which is installed on the inner end of the mounting base and located on the outer side of the inner cavity of one of the conveyor belts. The head end of the photoelectric sensor is provided with a rotating plate, which is movably mounted on the outer wall of the photoelectric sensor.
[0008] Preferably, the rotating plate is configured with an arc-shaped structure, and when the rotating plate is in an upright position, its top is higher than the conveyor belt.
[0009] Preferably, the inner cavity of the mounting base is provided with multiple sets of support components, the support components are located between two sets of conveyor belts, the support components include a support frame, and multiple sets of rollers are movably installed at the upper center of the support frame.
[0010] Preferably, the top of the roller is on the same horizontal plane as the top of the conveyor belt.
[0011] Preferably, the support frame is fixedly installed in the middle of the inner cavity of the mounting base, and multiple sets of support frames are evenly distributed at equal intervals.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This solution enables precise detection of transported objects, effectively preventing false alarms caused by difficulties in detecting perforated or other hollow objects during transport. The specific detection technology involves a rotating plate at the head of the photoelectric sensor. When the hollowed-out PCB substrate is transported via the conveyor belt, the contact between the substrate and the rotating plate compresses the head of the plate, causing it to rotate and cover the top of the photoelectric sensor, thus triggering it. Conversely, once the hollowed-out PCB substrate has been completely transported, or when no material is being transported, the rotating plate returns to its vertical position, releasing the trigger on the photoelectric sensor.

[0019] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0020] Example: Refer to Figure 1 - Figure 4 As shown, a conveying mechanism for preventing false alarms triggered by hollowed-out materials in this embodiment includes a mounting base 1. Conveyor belts 2 are correspondingly arranged on both sides of the inner cavity of the mounting base 1. The two sets of conveyor belts 2 are on the same horizontal plane. The left ends of the two sets of conveyor belts 2 are driven by a drive wheel 3, and the right ends of the two sets of conveyor belts 2 are driven by a driven wheel 6. The two sets of drive wheels 3 are coaxially connected through a connecting shaft 4, and one end of the connecting shaft 4 is connected to a drive motor 5.
[0021] The start-up drive motor 5 can drive the connecting shaft 4 to rotate, thereby driving the two sets of drive wheels 3 to rotate. Then, with the assistance of the driven wheel 6, it drives the conveyor belt 2 to rotate, thereby realizing the conveying of the hollowed-out PCB substrate.
[0022] The false alarm prevention detection component includes a photoelectric sensor 7, which is installed on the inner side of the mounting base 1 and located on the outer side of the inner cavity of one of the conveyor belts 2. The head end of the photoelectric sensor 7 is provided with a rotating plate 8, which is movably installed on the outer wall of the photoelectric sensor 7.
[0023] The photoelectric sensor 7 has a rotating plate 8 at its head. When the cut-out PCB substrate is conveyed by the conveyor belt 2, the cut-out PCB substrate comes into contact with the rotating plate 8 and squeezes the head of the rotating plate 8. Under the pressure, the rotating plate 8 rotates, thereby covering the top of the photoelectric sensor 7 and triggering the photoelectric sensor 7. Conversely, when the cut-out PCB substrate has been completely conveyed, or when no cut-out PCB substrate is conveyed, the rotating plate 8 will return to its vertical position and release the trigger on the photoelectric sensor 7.
[0024] The rotating plate 8 is designed with an arc shape, and when it is in an upright position, its top is higher than the conveyor belt 2. During the installation process, the bottom of the rotating plate 8 is heavier than its top, so that when the top loses pressure, the rotating plate 8 can rotate back to an upright position under its own weight. (Refer to...) Figure 3 As shown.
[0025] In some examples, multiple sets of support components are provided in the middle of the inner cavity of the mounting base 1. The support components are located between two sets of conveyor belts 2. The support components include a support frame 9. Multiple sets of rollers 10 are movably mounted in the middle of the upper end of the support frame 9. The top of the rollers 10 is on the same horizontal plane as the top of the conveyor belt 2, so that when the cut-out PCB substrate is conveyed on the conveyor belt 2, the rollers 10 can contact the bottom of the cut-out PCB substrate, thereby playing a role in stable support. Alternatively, when the rollers 10 are just located at the hole position of the cut-out PCB substrate, since the top of the rollers 10 is on the same horizontal plane as the top of the conveyor belt 2, it will not obstruct the conveying of the cut-out PCB substrate.
[0026] In some examples, the support frame 9 is fixedly installed in the middle of the inner cavity of the mounting base 1, and multiple sets of support frames 9 are evenly distributed at equal intervals.
[0027] The working principle of this utility model is as follows:
[0028] During operation, when the cut-out PCB substrate is conveyed onto conveyor belt 2 by the conveying equipment, the two sets of conveyor belts 2 rotate to move and transport the cut-out PCB substrate. When the cut-out PCB substrate moves to the rotating plate 8, it is pressed against the rotating plate 8 as it continues to move forward, causing the rotating plate 8 to rotate. When the rotating plate 8 rotates from a vertical position to a near-horizontal position, it covers the photosensitive unit on top of the photoelectric sensor 7, thus triggering the photoelectric sensor 7. This indicates that an object has passed above. After the cut-out PCB substrate has passed, the pressure is released, and the rotating plate 8 returns to a vertical position under the influence of gravity, awaiting the pressing of the next cut-out PCB substrate. The specific rotation pattern of the rotating plate 8 is shown in the reference [reference needed]. Figure 3 and Figure 4 As shown.
[0029] Through the above-described structure, this utility model can accurately detect the transmission of objects, thereby effectively avoiding the situation where it is difficult to detect objects with openwork or other similar features during transmission.
[0030] In addition, by providing a support assembly between the two sets of conveyor belts 2, including a support frame 9 and rollers 10 mounted on top of the support frame 9, the bottom of the cut-out PCB substrate can be supported by the rollers 10, thereby improving the stability of the cut-out PCB substrate during the conveying process.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
