Description

Technical Field

[0001] This application relates to the field of semiconductor manufacturing technology, and in particular to a crane blocking device and a crane system in a crane system. Background Technology

[0002] With rising labor costs and increasing levels of intelligent and sophisticated manufacturing, traditional manual material handling has become a bottleneck for production efficiency and quality. Therefore, the application of Automated Material Handling Systems (AMHS) is becoming increasingly widespread.

[0003] Overhead crane systems, as an important type of automated material handling system, are widely used in high-end manufacturing, especially in semiconductor wafer fabs and other fields within the semiconductor industry. Overhead crane systems improve the overall production process by increasing material transport efficiency, reducing labor costs, and minimizing contamination risks.

[0004] In related technologies, the crane system operates as follows: While running on the track, the crane system relies on look-forward sensors installed in front of each trolley to detect obstacles ahead, including trolleys already in front. For example, the look-forward sensor of the current trolley can emit infrared light. When there is a trolley in front of the current trolley, that trolley can reflect the infrared light through its reflector, causing the look-forward sensor of the current trolley to receive the signal and stop moving.

[0005] If a malfunctioning trolley is stopped on the track, the current procedure for handling the malfunctioning trolley is to use a remote control to stop a normally functioning trolley behind it to prevent collisions or other risks during the troubleshooting process.

[0006] The above-mentioned handling method is relatively convenient for single straight tracks. However, due to the complexity and variety of track types, such as the diverging and merging tracks in the crane system, where multiple tracks are merged into one track or one track is divided into multiple tracks, it is necessary to use a remote control to stop a trolley at the diverging and merging point. Obviously, this method is very cumbersome and takes a long time. As a result, it will cause congestion on the current track and affect the normal operation of the crane system.

It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.

[0056] In related technologies, if a malfunctioning trolley is stopped on the track of the overhead crane system, the current method for handling the malfunctioning trolley is to use a remote control to stop a normally operating trolley behind it to prevent collisions or other risks during the troubleshooting process.

[0057] The above-mentioned handling method is relatively convenient for single straight tracks. However, due to the complexity and variety of track types, such as tracks where the rails branch and merge in the overhead crane system, there are situations where multiple tracks are merged into one track and one track is divided into multiple tracks. When a faulty trolley stops within the range of the rail branch and merge, a trolley needs to be stopped at the branch and merge point using a remote control. However, using only this method may pose certain risks.

[0058] This is because when handling a faulty trolley, after clearing the alarm, the trolley needs to be reset to its origin position. Therefore, the trolley needs to be moved forward or backward, generally forward, meaning the alarmed trolley needs to be moved forward to the previous origin position. At the merging point, it's necessary to stop the trolley to prevent a collision. Additionally, certain codes need to be entered into the system to handle the faulty trolley. However, in some cases, the entered codes (e.g., incorrect code input) may cause the system to fail to recognize the faulty trolley, leading the trolley behind it to believe the faulty trolley no longer exists. Furthermore, since the forward-looking sensors on the trolleys are directly forward-facing or have a limited range, a faulty trolley stopped at the guide rail branching and merging point may be in the blind spot of the trolley behind it. Therefore, if the system fails to recognize the faulty trolley due to the code, and the forward-looking sensors also fail to recognize it, the trolley behind the faulty trolley may collide with it, causing a congestion on the current track and affecting the normal operation of the overhead crane system.

[0059] Furthermore, using a remote control to stop a non-faulty trolley can be difficult if the overhead crane system has complex tracks and a limited number of trolleys, requiring a long wait for the trolley to return. Additionally, controlling the trolley's stopping position using a remote control is also challenging.

[0060] In view of this, this application provides a schematic diagram of the structure of a crane blocking device in a crane system, as shown in the embodiment. Figure 1 As shown, the car-stopping device 1 in the overhead crane system includes a suspension mechanism 10 and a car-stopping plate 20.

[0061] In this embodiment, the suspension mechanism 10 includes a first end and a second end, wherein the first end of the suspension mechanism 10 is connected to the stop plate 20. Specifically, the first end of the suspension mechanism 10 is connected to the upper end of the stop plate 20. Figure 1 As shown, the car blocking device is used to be suspended in the overhead crane system via the second end of the suspension mechanism 10, located on the track behind the faulty car, and to block the non-faulty car from traveling by means of the car blocking plate 20.

[0062] In some possible embodiments, the barrier plate is made of lightweight materials such as carbon fiber. Thus, by using lightweight materials as part of the barrier device, the weight of the barrier device suspended on the track can be reduced.

[0063] In some possible embodiments, the stopping device can be suspended on a track located behind the faulty trolley. Optionally, the track distance between the location of the suspended stopping device and the faulty trolley can be determined according to the actual situation, for example, the track distance between the location of the suspended stopping device and the faulty trolley can be 50 centimeters.

[0064] This application provides a schematic diagram of the structure of a crane blocking device in a crane system, as shown in the embodiment. Figure 2 As shown, the car-stopping device 1 in the crane system includes a suspension mechanism 10, a car-stopping plate 20, and a drive device 30.

[0065] In some possible embodiments, the car-stopping device 1 further includes a drive device 30. That is, the car-stopping device 1 in the crane system may include a suspension mechanism 10, a car-stopping plate 20, and a drive device 30. Optionally, the drive device 30 may be disposed between the suspension mechanism 10 and the car-stopping plate 20.

[0066] Optionally, the drive unit 30 includes a first end and a second end, wherein the first end of the drive unit 30 is movably connected to the first end of the suspension mechanism 10, and the second end of the drive unit 30 is fixedly connected to the stop plate.

[0067] In other possible embodiments, such as Figure 2 As shown, a connecting rod is also provided between the drive device 30 and the suspension mechanism 10, with both ends of the connecting rod connected to the first end of the drive device 30 and the first end of the suspension mechanism 10, respectively. Optionally, the connection between the two ends of the connecting rod can be a fixed connection or a detachable connection.

[0068] In some possible embodiments, the length of the connecting rod located between the drive unit 30 and the suspension mechanism 10 is fixed.

[0069] In some other possible embodiments, the length of the connecting rod located between the drive unit 30 and the suspension mechanism 10 is adjustable. That is, the connecting rod is a telescopic connecting rod.

[0070] Thus, the length of the entire car-stopping device can be extended or shortened by a fixed-length connecting rod or a telescopic connecting rod, making it suitable for blocking trolleys of various sizes in the overhead crane system.

[0071] In some possible embodiments, the drive device 30 mentioned above can be a motor or an electric motor. A motor or electric motor can convert electrical energy into mechanical energy. In this embodiment, the drive device 30 can be used to drive the suspension mechanism 10 to rotate a preset angle.

[0072] In one optional embodiment, the preset angle may include a range of 80 to 90 degrees. Optionally, the preset angle may be 90 degrees, 80 degrees, or 85 degrees.

[0073] This application provides a schematic diagram of the movement of a wheel stop in a wheel stop device, such as... Figure 3 As shown, in the initial state, with the wider side of the suspension mechanism as an example, the suspension mechanism 10 (the wider side of the suspension mechanism) can be parallel to the track in the overhead crane system. After the drive device 30 drives the suspension mechanism 10 to rotate by a preset angle, such as 90 degrees clockwise or counterclockwise, the suspension mechanism 10 (the wider side of the suspension mechanism) can be perpendicular to the track in the overhead crane system. During this process, the baffle plate 20 remains perpendicular to the track in the overhead crane system.

[0074] In this embodiment, the car-stopping device further includes a distance sensor. This embodiment provides a schematic diagram of the structure of a car-stopping device in a crane system, as shown below. Figure 4 As shown, the car-stopping device 1 in the crane system includes a suspension mechanism 10, a car-stopping plate 20, a drive device 30, and a distance sensor 40.

[0075] Optionally, the distance sensor 40 can be an ultrasonic sensor or an infrared light sensor.

[0076] In this embodiment, the distance sensor 40 can be mounted on the baffle plate 20, on the side opposite to the faulty trolley. Alternatively, the distance sensor 40 can be mounted at the center point of the baffle plate 20.

[0077] Of course, the distance sensor 40 can also be set in other positions on the barrier plate 20 or on other components in the barrier device, such as on the suspension mechanism 10.

[0078] In some possible embodiments, the distance sensor 40 is used to detect the distance between the non-faulty trolley and the blocking device traveling on the track. If the distance between the non-faulty trolley and the blocking device is detected to meet the preset distance, a first command can be issued. The first command can be used to instruct the drive device to drive the suspension mechanism 10 to rotate by a preset angle, that is, to instruct the drive device to drive the suspension mechanism 10 to rotate from the initial state to the working state.

[0079] Optionally, the preset distance can be determined based on the actual obstruction caused by the overhead crane system.

[0080] In this embodiment, the car-stopping device also includes an indicator light. This embodiment provides a structural schematic diagram of a car-stopping device in a crane system, as shown below. Figure 5 As shown, the car-stopping device 1 in the overhead crane system includes a suspension mechanism 10, a car-stopping plate 20, a drive device 30, a distance sensor 40, and an indicator light 50.

[0081] In this embodiment of the application, the indicator light 50 can be installed on any component of the barrier device 1, such as on the barrier plate 20 or on the suspension mechanism 10.

[0082] In an alternative embodiment, the indicator light 50 may be arranged in the form of a light strip around the perimeter of the barrier 20. This increases the visibility of the indicator light, making it more clearly visible to staff.

[0083] In this embodiment of the application, the first instruction is used to instruct the indicator light to switch from a first color to a second color, or the first instruction is used to instruct the indicator light to switch from a closed state to an open state.

[0084] Specifically, the distance sensor 40 is used to detect the distance between the non-faulty trolley traveling on the track and the blocking device. If the distance between the non-faulty trolley and the blocking device meets the preset distance, a first command can be issued. The first command can be used to indicate that the indicator light changes from a first color to a second color, or the first command can be used to indicate that the indicator light changes from a closed state to an open state, that is, the indicator light generates a light prompt effect to indicate that the blocking device has switched to the blocking state.

[0085] In summary, Figure 5 The first command issued by the distance sensor in the barrier device shown can not only instruct the drive device to drive the suspension mechanism 10 to rotate by a preset angle, but also instruct the indicator light 50 to generate a light prompt effect to indicate that the barrier device has switched to the barrier state.

[0086] In this embodiment, the car-stopping device further includes a loudspeaker. This embodiment provides a structural schematic diagram of a car-stopping device in a crane system, as shown below. Figure 6As shown, the car-stopping device 1 in the crane system includes a suspension mechanism 10, a car-stopping plate 20, a drive device 30, a distance sensor 40, and a speaker 60.

[0087] In this embodiment, the speaker 60 can be mounted on any component of the barrier device 1, such as on the barrier plate 20 or on the suspension mechanism 10. Figure 6 As shown, the speaker 60 can be installed at the bottom of the baffle plate 20.

[0088] In some possible embodiments, the first instruction issued by the distance sensor 40 may instruct the speaker 60 to emit a first voice; or; the first instruction may also be used to instruct the speaker to switch the emitted first voice to a second voice; or; the first instruction may also be used to instruct the speaker to switch the emitted first voice at a first frequency to a first voice at a second frequency, that is, the first instruction may instruct the speaker to generate a sound prompt effect to indicate that the vehicle blocking device has switched to the vehicle blocking state.

[0089] In summary, Figure 6 The first command issued by the distance sensor in the barrier device shown can not only instruct the drive device to drive the suspension mechanism 10 to rotate by a preset angle, but also instruct the speaker to generate an audible prompt effect to indicate that the barrier device has switched to the barrier state.

[0090] This application provides a schematic diagram of the structure of a crane blocking device in a crane system, as shown in the embodiment. Figure 7 As shown, the car-stopping device 1 in the crane system includes a suspension mechanism 10, a car-stopping plate 20, a drive device 30, a distance sensor 40, an indicator light 50, and a speaker 60.

[0091] Figure 7 The first command issued by the distance sensor in the barrier device shown can not only instruct the drive device to drive the suspension mechanism to rotate 10 turns to a preset angle, but also instruct the indicator light to generate a light prompt effect and use the speaker to generate a sound prompt effect to indicate that the barrier device has switched to the barrier state.

[0092] In some possible embodiments, the vehicle blocking device further includes a control module for receiving a first instruction from the pepper distance sensor 40 and sending the first instruction to the drive unit 30, the indicator light 50, and the speaker 60, so that the drive unit 30, the indicator light 50, and the speaker 60 perform the actions as described above.

[0093] In this way, the entire vehicle stopping device can be automated through the control module.

[0094] In this embodiment, the car-stopping device further includes a power supply, a power switch, and a reset switch. This embodiment provides a schematic diagram of the structure of a car-stopping device in a crane system, as shown below. Figure 8 As shown, the car-stopping device 1 in the overhead crane system includes a suspension mechanism 10, a car-stopping plate 20, a drive device 30, a distance sensor 40, an indicator light 50, a speaker 60, a power switch 70, a power supply 80, and a reset switch 90.

[0095] like Figure 8 As shown, a power supply device is also connected to the lower end of the barrier plate of the vehicle blocking device. This power supply device includes a power switch 70 and a power supply 80. A reset switch 90 is also provided on the suspension mechanism 10.

[0096] Optionally, power supply 80 provides power to the entire vehicle stop device 1, power supply source 70 is triggered to start so that power supply 80 provides power to the entire vehicle stop device 1, and power supply source 70 is also triggered to shut down so that power supply 80 cuts off the power to the entire vehicle stop device 1.

[0097] Optionally, the reset switch 90 is used to send a second command or a third command when triggered, wherein the second command is used to instruct the drive device to drive the suspension mechanism 10 to rotate by a preset angle, and the third command is used to instruct the drive device to drive the suspension mechanism 10 to rotate in the opposite direction by a preset angle.

[0098] Thus, the presence of the reset switch 90 allows for manual or automatic operation to rotate the suspension mechanism 10, indicating that the vehicle stop device is in operation.

[0099] In some possible embodiments, the barrier device also includes a reflector that may be disposed on the barrier plate.

[0100] Specifically, the reflective element can be a reflective sticker, which can be affixed to the side of the light-blocking plate opposite to the faulty trolley, i.e., the reflective sticker can be away from the faulty trolley. Optionally, the reflective element is used to reflect infrared light from the non-faulty trolley.

[0101] This application provides a circuit structure diagram of a crane stopping device in an overhead crane system, as shown in the embodiment. Figure 9 As shown, the positive and negative wires are connected to the power supply, power switch, reset switch, distance sensor, speaker, indicator light, drive device and control module, respectively.

[0102] Optionally, the control module is connected to signal lines via a reset switch, a distance sensor, a speaker, an indicator light, and a drive device. The control module receives a first command from the distance sensor and transmits the first command to the speaker, indicator light, and drive device. Additionally, the control module receives a second and a third command from the reset switch and can transmit either the second or third command to the speaker, indicator light, and drive device.

[0103] The above-mentioned vehicle blocking device is described below through a specific implementation method:

[0104] When a malfunctioning trolley is stopped on the track, before using the stopping device, the operator can press the power switch to power the entire stopping device. At this time, the indicator light will be a solid green, and the speaker will emit a low-frequency "beep" sound. The operator can then lift the stopping device and hang it on the track, with the suspension point behind the malfunctioning trolley. The suspension mechanism should be parallel to the track in the overhead crane system, and the stopping plate should be perpendicular to the track.

[0105] In one optional embodiment, if a non-faulty trolley approaches from behind, its forward-looking sensor emits infrared light. A luminous sticker on the light-blocking plate reflects this infrared light. When the non-faulty trolley's forward-looking sensor receives the reflected infrared light, it slows down the trolley until it stops. Simultaneously, when the non-faulty trolley is within a preset distance of the blocking device, a distance sensor receives the infrared light, triggers it, and issues a first command. This first command is sent to the control module, which then sends it to the speaker, indicator lights, and drive unit.

[0106] Optionally, after receiving the first instruction, the indicator light can change from green to red, and the speaker can emit a "Please be aware of the vehicle blocking" warning sound based on the first instruction. At the same time, the drive device drives the suspension mechanism to rotate at a preset angle, and the suspension mechanism is perpendicular to the track in the crane system so that the vehicle blocking device is in working condition.

[0107] In another optional embodiment, if no non-faulty trolley travels over for an extended period of time, the reset switch can be pressed directly. At this time, the reset switch issues a second instruction, which is sent to the control module and then to the speaker, indicator light, and drive device.

[0108] Optionally, after receiving the second instruction, the indicator light can change from green to red, and the speaker can emit a "Please be aware of the vehicle blocking" warning sound based on the second instruction. At the same time, the drive unit drives the suspension mechanism to rotate at a preset angle, and the suspension mechanism is perpendicular to the track in the crane system so that the vehicle blocking device is in working condition.

[0109] The blocking device was placed behind the faulty trolley and blocked the normal-moving non-faulty trolleys behind it.

[0110] Optionally, once the faulty trolley has resolved the fault, a reset switch can be pressed. At this time, the reset switch issues a third command, which is sent to the control module and then to the speaker, indicator lights, and drive unit.

[0111] Optionally, after receiving the second command, the indicator light can change from red to light color, the speaker will be muted, and at the same time, the drive unit will drive the suspension mechanism to reverse the preset angle so that the blocking device is in its initial state and the blocking device can be removed.

[0112] In summary, the application of the blocking device can solve the problem of the system being unable to identify faulty trolleys due to code issues, and the forward-looking sensor also failing to recognize the faulty trolley, which can lead to collisions between trolleys behind the faulty trolley.

[0113] In addition, the application of the vehicle device also solves the problem that when there are few vehicles, it is necessary to wait for a long time for a vehicle to arrive when a non-faulty vehicle is stopped by remote control.

[0114] At the same time, the vehicle stopping device makes it easier to control the vehicle's position.

[0115] Accordingly, this application also provides a crane system, which includes a track, a trolley, and a stopping device in the crane system described above.

[0116] The electronic device described in the embodiments of this application can be any electronic product or device such as a smartphone, desktop computer, tablet computer, laptop computer, digital assistant, augmented reality (AR) / virtual reality (VR) device, smart voice interaction device, smart home appliance, smart wearable device, vehicle terminal device, etc., or any intermediate product including the above-mentioned storage device.
