Description

Technical Field

[0001] This invention relates to the field of object transport technology, and in particular to a transport reversal device, system and method. Background Technology

[0002] With the rapid development of semiconductor technology and the increasing market demand for semiconductor products, semiconductor manufacturers are increasing the number of production equipment and the complexity of production processes in order to improve production capacity. As a result, the number of zones for the configuration of equipment within the factory is gradually increasing, and the efficiency of transportation between these zones through automated handling systems (AMHS) has become one of the important factors affecting production efficiency.

[0003] In traditional semiconductor equipment manufacturing plants, different production equipment is divided into zones. The track design between zones typically uses unidirectional transport equipment combined with U-shaped turntables, with trolleys moving between zones. The number and placement of the turntables are determined based on the results of the initial transport plan simulation.

[0004] However, the placement of U-shaped turntables is limited by their own structure and the factory's control equipment, preventing dense deployment. This results in trolleys having to detour a long distance for short-distance transport to the other side, leading to low transport efficiency. Furthermore, they must proceed in sequence; if a trolley in front stops, the trolleys behind it must wait, causing excessive time and further reducing efficiency. Additionally, with the rapid updates to semiconductor manufacturing processes and frequent equipment replacements, initial transport planning simulations are no longer applicable to updated processes. Improvements can only be achieved through track modifications, which significantly impact production efficiency. Therefore, the original design is often retained, leading to increasingly lower transport efficiency. Summary of the Invention

[0005] Therefore, it is necessary to address the problems of long detour transport distances, low efficiency, and inability to adapt to the needs of production equipment replacement in the aforementioned background technology by providing a transmission reversing device, system, and method with automatic reversing function.

[0034] The controller controls the transmission reversing component to stop rotating based on the position signal received by the controller.

[0035] In the above-mentioned transmission reversal method, since a detection device is provided on the transmission reversal component to detect its rotation angle, the controller controls the transmission reversal component to stop rotating based on the position signal of the transmission reversal component detected by the detection device, and then controls the rotation angle of the transmission reversal component based on the position information of the transmission reversal component detected by the detection device.

[0036] In one embodiment, the reversing trigger signal is a start signal for transmitting the reversing component.

[0037] In one embodiment, detecting the position information of the transmission reversing component to generate a position signal further includes:

[0072] One embodiment of this application provides a transmission direction-changing device, such as... Figure 1 As shown, it includes:

[0073] The transmission direction-changing component 10 is used to start or stop rotation after receiving a control signal from the controller;

[0074] The detection device 40 is used to detect the position information of the reversing component 10 to generate a position signal;

[0075] The controller 20 is used to control the transmission direction-changing component 10 to stop rotating based on the position signal.

[0076] Specifically, if the position signal acquired by the controller 20 meets the preset standard, the controller controls the transmission direction-changing component 10 to stop rotating, so as to change the direction of the transmission object set on the upper surface of the transmission direction-changing component 10.

[0077] Furthermore, such as Figure 1As shown, the controller 20 can be configured to control the transmission reversing component 10 to rotate around a preset rotating shaft 111, thereby driving the detection device set on the transmission reversing component 10 to rotate. When the position signal detected by the detection device 40 obtained by the controller 20 meets the preset standard, the controller controls the transmission reversing component 10 to stop rotating, thereby controlling the angle of rotation of the transmission reversing component 10 around the preset rotating shaft 111, thereby changing the direction of the transmission object set on the upper surface of the transmission reversing component 10.

[0078] One embodiment of this application provides a transmission direction-changing device, such as... Figure 2 As shown, it includes:

[0079] The transmission reversing component is used to start or stop rotation after receiving a control signal from the controller. The transmission reversing component includes a rotating part 11 for rotating with the motor 13, which is connected to the controller 20;

[0080] The detection device includes a positioner 12 and a positioning sensor 30. The positioner 12 can be disposed on the outside of the rotating part 11 and is used to locate the position information of the rotating part 11. The positioning sensor 30 is used to detect the position information of the rotating part 11 to generate a position signal.

[0081] The controller 20 controls the rotating part 11 to stop rotating based on the position signal.

[0082] Specifically, the locator 12 can be configured to locate the position information of the rotating part 11 after it has rotated to a preset angle. The positioning sensor 30 can send this position signal after detecting the position information acquired by the locator. The controller can receive this position signal and, by setting the relative position between the locator 12 and the positioning sensor 30 on the rotating part 11, can control the rotating part 11 to rotate around a preset axis by an angle. For example, under normal conditions, the positioning sensor 30 does not receive the signal emitted by the locator 12. When the rotating part 11 rotates around the preset axis by a preset angle, the positioning sensor 30 detects the locator's position information and generates a position signal, which is then received by the controller 20. If the controller receives the position signal sent by the positioning sensor 30, it controls the rotating part 11 to stop rotating. In this way, the rotation angle of the rotating part 11 around the preset axis can be controlled.

[0083] Furthermore, in the above embodiments, the positioning sensor includes a positioning hole; the positioner includes an elastic part and a positioning terminal, the positioning terminal being connected to the rotating part through the elastic part; wherein, if the positioning terminal is located inside the positioning hole, the positioning sensor sends a positioning signal to the controller, and the controller controls the motor to stop rotating.

[0084] Furthermore, in the above embodiments, the positioning sensor 30 is an interruption-type sensor, which can be configured as follows: Figure 3As shown, the positioning sensor 30 includes a signal transmitter 31 and a signal receiver 32, with the receiver 32 connected to the controller. A positioning hole 33 exists between the transmitter 31 and the receiver 32. If there is no obstruction in the positioning hole 33, the receiver 32 can receive the signal transmitted by the transmitter 31; conversely, if there is an obstruction in the positioning hole 33, the signal transmission path between the transmitter 31 and the receiver 32 is interrupted, and the receiver 32 cannot receive the signal transmitted by the transmitter 31. The controller can control the rotation of the transmission deflection component to start or stop based on whether the receiver 32 receives a signal. Therefore, by setting the relative position of the positioning sensor 30 and the obstruction on the transmission deflection component, and then controlling the rotation of the transmission deflection component to start or stop based on whether the receiver 32 receives a signal transmitted by the transmitter 31, the angle of rotation of the transmission deflection component around a preset axis can be controlled, thereby changing the direction of the object transported by the transmission deflection component.

[0085] Furthermore, in the above embodiments, the locator 12 can be configured as follows: Figure 4 As shown, it includes a positioning terminal 121 and an elastic part 122; wherein, the positioning terminal 121 is connected to the transmission direction-changing component through the elastic part 122. When the positioning terminal 121 is located inside the positioning hole, the positioning terminal 121 can block the signal transmission path between the signal transmitting end and the signal receiving end, so that the signal receiving end in the positioning sensor cannot receive the signal transmitted by the signal transmitting end. When the signal receiving end cannot receive the signal transmitted by the signal transmitting end, the controller can control the transmission direction-changing component to start or stop rotating. In this embodiment, the positioning terminal 121 can be set to be spherical, and the elastic part 122 can be a spring. The spherical positioning terminal is connected to the transmission direction-changing component through the spring. When the positioning terminal 121 is located inside the positioning hole, the signal transmitted from the signal transmitting end to the signal receiving end in the positioning sensor is blocked, that is, the signal receiving end cannot receive the signal transmitted by the signal transmitting end. Since the signal receiving end is connected to the controller, the controller can control the transmission direction-changing component to start or stop rotating according to whether the signal receiving end receives a signal. Therefore, by setting the relative position of the positioning sensor and the positioner set on the transmission reversing component, and then controlling whether the signal receiving end receives the signal emitted by the signal transmitting end, the transmission reversing component can be controlled to start or stop rotating, thereby controlling the angle of rotation of the transmission reversing component around the preset axis, so as to change the direction of the object being transported by the transmission reversing component.

[0086] Furthermore, in the above embodiments, such as Figure 5 As shown, the positioning terminal 121 and the positioning hole 33 can be set to match in shape and size. When the positioning terminal is located in the positioning hole 33, the signal transmitted from the signal transmitter to the signal receiver is blocked, that is, the signal receiver cannot receive the signal transmitted by the signal transmitter.

[0087] Furthermore, in the above embodiments, such as Figure 5 As shown, two positioning sensors 30 can be installed, each including a signal transmitter 31 and a signal receiver 32. A positioning hole 33 exists between the signal transmitter 31 and the signal receiver 32. If there is no obstruction in the positioning hole 33, the signal receiver 32 can receive the signal transmitted by the signal transmitter 31; conversely, if there is an obstruction in the positioning hole 33, the signal transmission path between the signal transmitter 31 and the signal receiver 32 is interrupted, and the signal receiver 32 cannot receive the signal transmitted by the signal transmitter 31. The signal receivers of both positioning sensors are connected to the controller. The straight line containing the two positioning sensors 30 passes through the center of the rotating part 11. Figure 5 The left-center positioning sensor 30 is the positioning detection point where the rotating part 11 begins to rotate; that is, under normal conditions, the positioning terminal 121 is located at... Figure 5 The left positioning sensor's signal receiver 32 is located inside the positioning hole, preventing it from receiving signals from the left positioning sensor's transmitter. When the rotating part 11 begins to rotate, it moves the positioning terminal 121 out of the left positioning sensor's positioning hole, allowing the left positioning sensor's signal receiver 32 to receive signals from the left positioning sensor's transmitter 31. The left positioning sensor's signal receiver 32 is connected to the controller. When it receives a signal from the transmitter, it indicates that the rotating part 11 has started to rotate, moving the positioning terminal 121 out of the positioning hole 33. When the rotating part 11 rotates 180 degrees, it moves the positioning terminal 121 into the right positioning sensor's positioning hole, preventing the right positioning sensor's signal receiver from receiving signals from the right positioning sensor's transmitter. Since the right positioning sensor's signal receiver is connected to the controller, when the right positioning sensor's signal receiver no longer receives signals from the transmitter, the controller can stop the rotating part 11 from rotating. Figure 5 This document merely illustrates one specific embodiment of the present application. By setting the relative position between the positioning sensor and the elastic terminal in the non-activated state, the angle of rotation of the rotating part 11 around the normal passing through the center point of its upper surface can be changed, thereby controlling the direction of the transport object placed on the upper surface of the rotating part 11.

[0088] Furthermore, in the above embodiments, a transmission component detection sensor (not shown) is also included to detect the transmission component and transmit a reversal trigger signal to the controller. When the transmission component is placed in a suitable position on the transmission reversal device, the transmission component detection sensor detects the transmission component and sends a reversal trigger signal to the controller. The controller controls the rotating part to start rotating based on the reversal trigger signal.

[0089] One embodiment of this application provides a transmission direction-changing device, such as... Figure 6 As shown, the controller 20 controls two motors 13, each of which rotates to drive a rotating part 11. The working principle of the controller 20 controlling one motor 13 to rotate, thereby driving one rotating part 11, is as follows: Figure 2 The embodiments illustrated herein are intended to illustrate how the transmission steering function described in the embodiments of this application can be achieved by controlling at least two rotating parts 11 through a single controller 20. Figure 6 The illustrated embodiments are not intended to limit this application. Depending on the specific working scenario, a controller 20 can be set to control multiple rotating parts 11, but the maximum control capacity of the controller 20 cannot be exceeded.

[0090] One embodiment of this application provides a transmission direction-changing system, such as... Figure 7 As shown, it includes:

[0091] The transmission reversing component is used to start or stop rotation after receiving a control signal from the controller. The transmission reversing component includes a rotating part 11 for rotating with the motor 13, which is connected to the controller 20;

[0092] The detection device includes a positioner 12 and a positioning sensor 30. The positioner 12 can be disposed on the outside of the rotating part 11 and is used to position and transmit the position information of the direction-changing component. The positioning sensor 30 is used to detect the position information of the rotating part 11 to generate a position signal.

[0093] The controller 20 controls the rotating part 11 to stop rotating based on the position signal sent by the acquired positioning sensor 30.

[0094] Specifically, if the position signal acquired by the controller meets the preset standard, the controller stops rotating the rotating part 11 to change the direction of the transport object set on the upper surface of the rotating part 11.

[0095] Furthermore, the transmission direction-changing system in the above embodiments may further include:

[0096] The server is connected to the controller 20, and the controller 20 can obtain the direction change trigger signal through the server; the server can be connected to a mobile terminal device or a computer.

[0097] Furthermore, in the above embodiments, the number of controllers can be two or more, each controller being connected to the server. Each controller can control the rotation of one or more motors, and the rotation of each motor drives the connected rotating part 11 to rotate, achieving the following: Figure 5 The working principle of the schematic embodiment is to change the direction of the transport object 50 disposed on the upper surface of the rotating part 11.

[0098] Specifically, in the above embodiment, two positioning sensors 30 can be provided. The positioning sensors 30 are as follows: Figure 3 As shown, it includes a signal transmitter 31 and a signal receiver 32, with a positioning hole 33 between the signal transmitter 31 and the signal receiver 32. Positioner 12 as... Figure 4 As shown, it includes a positioning terminal 121 and an elastic part 122; wherein, the positioning terminal 121 is connected to the rotating part 11 through the elastic part 122, as shown. Figure 5 As shown; if the positioning terminal 121 is located inside the positioning hole 33, the positioning terminal 121 can isolate the signal transmission path between the signal transmitter 31 and the signal receiver 32, so that the signal receiver 32 cannot receive the signal emitted by the signal transmitter 31. When the signal receiver 32 cannot receive the signal emitted by the signal transmitter 31, the controller can control the rotating part 11 to stop rotating. The straight line where the two positioning sensors 30 are located can be set to pass through the center of the rotating part 11, and the left positioning sensor 30 can be set as the positioning detection point at which the rotating part 11 starts to rotate. That is, under normal conditions, the positioning terminal 121 is located inside the positioning hole of the left positioning sensor, so that the signal receiver of the left positioning sensor cannot receive the signal emitted by the signal transmitter of the left positioning sensor. When the rotating part 11 starts to rotate, it drives the positioning terminal 121 to move out of the positioning hole of the left positioning sensor, so that the signal receiver of the left positioning sensor receives the signal emitted by the signal transmitter of the left positioning sensor. When the rotating part 11 rotates 180 degrees, it drives the positioning terminal 121 to move into the positioning hole of the right positioning sensor, so that the signal receiver of the right positioning sensor cannot receive the signal emitted by the signal transmitter of the right positioning sensor. Since the signal receiving end of the right positioning sensor is connected to the controller, the controller can control the rotating part 11 to stop rotating when the signal receiving end of the right positioning sensor does not receive the signal from the signal transmitting end of the right positioning sensor. In other embodiments of this application, the angle of rotation of the rotating part 11 around the normal passing through the center point of its upper surface can be changed by setting the relative position between the positioning sensor and the elastic terminal in the non-activated state, thereby controlling the direction of the transport object 50 placed on the upper surface of the rotating part 11.

[0099] Figure 8This is a schematic diagram of a traditional semiconductor object transport system. Production area 1 and production area 2 each have several production stations 60. A passageway 80 connects production area 1 and production area 2. Carts move within the passageway 80 to transport semiconductor objects to suitable stations for further processing. For example, to transport a semiconductor object from production area 2 to the corresponding station in production area 1, a first cart 71 moves the semiconductor object from production area 2 to the corresponding station in production area 1. The first cart 71 carries the semiconductor object 180 degrees and then travels along the detour route shown in the first route 91 to transport the semiconductor object to the corresponding station in production area 1. A second cart 72 in production area 1 then transports the semiconductor object to the appropriate station in production area 1.

[0100] Figure 9 To and Figure 8 This application provides a schematic diagram of an application scenario for a transmission redirection system under the same conditions. For example, if it is necessary to transport semiconductor objects, or other transport components such as front-opening unified pods (FOUPs), from production area 2 to a corresponding workstation in production area 1, the first trolley 71 needs to move the semiconductor object located in production area 2 to the corresponding workstation in production area 1. The first trolley 71 drives the semiconductor object to travel along a straight route as shown in the second route 92 to a transmission redirection device (not shown) located in channel 80. After the transmission redirection device rotates the semiconductor object 180 degrees, the second trolley 72 located in production area 1 then transports the semiconductor object to the appropriate workstation in production area 1. The specific transmission redirection principle of the transmission redirection device is as follows: Figure 10 As shown, the first trolley 71 transfers the semiconductor object to the transfer redirection device (the component in the middle of the channel). The rotating part 11 of the transfer redirection device rotates 180 degrees, causing the semiconductor object to rotate 180 degrees before transferring it to the second trolley 72. The second trolley 72 then transports the semiconductor object to a suitable workstation in production area 1. The trajectory length of the second route 92 is significantly shorter than that of the first route 91, thus significantly improving the efficiency of semiconductor device handling between different workstations. When the relative positions between different workstations in the production area change, the angle of the transfer redirection can be adjusted to adapt to the needs of the new environment, thus effectively adapting to the handling requirements of different working environments. The transfer redirection device can be located on the ground, with the first trolley 71 and the second trolley 72 descending to transfer objects; alternatively, a slide rail can be installed on the top of the transfer redirection device to fix it to the ceiling, allowing the first trolley 71 and the second trolley 72 to complete object redirection without descending; furthermore, a corresponding track can be installed in the middle of the factory area to facilitate the installation of factory equipment.

[0101] Furthermore, the transmission direction-changing principle in the above embodiments can also be as follows: Figure 11 As shown, the transmission reversing device is set on the ground, and the first trolley 71 and the second trolley 72 descend to transfer the object. Specifically, the controller can control the rotating part 11 to rotate 180 degrees, causing the support frame 112 to rotate 180 degrees. The support frame 112 then rotates the semiconductor object, thus achieving the reversing function for the transferred semiconductor object. For example, as... Figure 9 As shown, it is necessary to transport semiconductor components from production area 2 to the corresponding workstation in production area 1. The first trolley 71 moves the semiconductor components from production area 2 to the corresponding workstation in production area 1. The first trolley 71 drives the semiconductor components along a straight route as shown in the second route 92, transporting them to the transmission redirection device (not shown) located in channel 80. The controller can control the rotating part 11 to rotate 180 degrees, causing the support frame 112 to rotate 180 degrees. The support frame 112 then rotates the semiconductor components 180 degrees. The second trolley 72 in production area 1 then transports the semiconductor components to the appropriate workstation in production area 1. Since the transmission redirection device in this embodiment may be located in different positions within the production area, the shape of the support frame 112 can be customized according to the specific application scenario to adapt to different location and space requirements. Figure 11 This illustration is intended to demonstrate one specific implementation of the embodiments of this application and is not intended to limit the scope of this application. Alternatively, a slide rail connector (not shown) can be provided at the top of the transmission direction-changing device, and the device can be fixed to a slide rail (not shown) in the middle of the ceiling passageway via the slide rail connector. Preferably, the support frame 112 includes an inner wall and an outer wall. The outer wall is fixedly connected to the slide rail, and a fixing member (not shown) is provided on the inner wall to fix the semiconductor object, such as snapping the semiconductor object into the cavity surrounded by the inner wall. The inner wall is connected to the rotating part 11, and under the drive of the rotating part 11, the inner wall and the semiconductor object rotate together. A sensor or positioner can be provided on the rotating part 11. When the rotating part 11 rotates by a preset angle, the inner wall stops rotating, thereby changing the direction of the transmitted semiconductor object.

[0102] The steering control device, system, and method provided in this application embodiment can be applied to automated production lines for other products, making it easier to rotate the transported object to a suitable angle so that the robot arm can grip the object for the next operation. Compared with the traditional handling method that requires the trolley to turn around, it improves the handling efficiency. It can adapt to the changing needs of the automated production line by changing the angle of the transport direction.

[0103] The controller in this application embodiment may include at least one of a microcontroller, an in-vehicle PLC, an ARM processor, a DSP, a programmable logic controller, etc.

[0104] One embodiment of this application provides a transmission direction-changing method, such as... Figure 12 As shown, it includes:

[0105] Step 202: Generate a position signal based on the position information of the transmission reversing component detected by the detection device.

[0106] A detection device can be installed on the transmission reversing component. This device detects the position information of the transmission reversing component after it has rotated to a preset angle, thereby generating a position signal. Based on the position signal detected by the detection device, the controller can then control the rotation angle of the transmission reversing component.

[0107] Step 204: Control the transmission direction-changing component to stop rotating based on the position signal received by the controller.

[0108] When the position information detected by the detection device reaches a preset standard, the transmission reversing component can be controlled to stop rotating, thereby controlling the rotation angle of the transmission reversing component. For example, when the position point detected by the detection device on the transmission reversing component rotates around the axis of rotation of the transmission reversing component by a preset angle, a position signal can be sent to the controller, and the controller controls the transmission reversing component to stop rotating. In this embodiment, the rotation of the transmission reversing component can be controlled by the controller controlling the rotation of a motor. By setting the form of motor rotation driving the transmission reversing component, the rotation axis of the transmission reversing component can be changed. The transmission reversing component may include a servo motor, and the rotation of the transmission reversing component can be controlled by controlling the rotation of the motor, thereby controlling the rotation angle of the transmission reversing component around the preset axis.

[0109] In the above embodiment of the transmission reversal method, since a detection device for detecting the rotation angle can be provided on the transmission reversal component, the controller controls the rotation angle of the transmission reversal component according to the position signal detected by the detection device, thereby controlling the direction of the object being transported by the transmission reversal component.

[0110] One embodiment of this application provides a transmission direction-changing method, such as... Figure 13 As shown, it includes:

[0111] Step 202: Generate a position signal based on the position information of the transmission reversing component detected by the detection device.

[0112] Step 203: Determine the position of the positioning sensor according to a preset angle, where the angle is the angle by which the transmission direction-changing component rotates around a preset axis. The positioning sensor is used to detect the position information of the positioner set on the transmission direction-changing component to generate a position signal.

[0113] The position of the positioning sensor can be set according to the required rotation angle of the object being transported by the transmission deflection component. Since the positioning sensor detects the position information of the positioner installed on the transmission deflection component, the controller can control the rotation angle of the transmission deflection component based on this position information. The transmission deflection component may include a servo motor, and its rotation is controlled by controlling the motor's rotation. Under normal conditions, when the positioning sensor cannot detect the position information of the positioner, the controller can control the motor to rotate by the preset angle until the positioning sensor detects the position information. At this point, the positioning sensor sends the detected position information to the controller, and the controller stops the motor's rotation. This achieves the control of the transmission deflection component to rotate around a preset axis by a preset angle, ensuring that the object being transported by the transmission deflection component rotates to the required direction.

[0114] Step 204: Control the transmission direction-changing component to stop rotating based on the position signal received by the controller.

[0115] When the controller detects that the position information sent by the locator reaches a preset standard, it can control the transmission reversing component to stop rotating, and thus control the rotation angle of the transmission reversing component. For example, when the controller detects that the position point sent by the locator on the transmission reversing component has rotated around the axis of the transmission reversing component by a preset angle, the controller can send a signal to stop the rotation of the transmission reversing component. In this embodiment, the rotation of the transmission reversing component can be controlled by the controller controlling the rotation of the motor. By setting the form of the motor driving the transmission reversing component, the rotation axis of the transmission reversing component can be changed.

[0116] In the transmission reversal method described above, since a positioner for detecting the rotation angle is provided on the transmission reversal component, the controller controls the rotation angle of the transmission reversal component according to the position signal of the positioner, thereby controlling the direction of the object being transported by the transmission reversal component.

[0117] Furthermore, the positioning sensor in the above embodiments may include a positioning hole, and the positioner includes an elastic part and a positioning terminal; wherein, the positioning terminal is connected to the transmission reversing component through the elastic part; if the positioning terminal is located within the positioning hole, the transmission reversing component is controlled to stop rotating. In one embodiment of this application, a positioning sensor is provided as follows: Figure 3 As shown; in one embodiment of this application, a locator is provided as follows: Figure 4 As shown.

[0118] Furthermore, in the above embodiments, the shape and size of the positioning terminal 121 and the positioning hole 33 can be matched, such as... Figure 5As shown. When the positioning terminal is located inside the positioning hole 33, the signal transmitted from the signal transmitter to the signal receiver is blocked, that is, the signal receiver cannot receive the signal transmitted by the signal transmitter.

[0119] Furthermore, such as Figure 5 As shown, two positioning sensors 30 can be installed, each including a signal transmitter 31 and a signal receiver 32. A positioning hole 33 exists between the signal transmitter 31 and the signal receiver 32. If there is no obstruction in the positioning hole 33, the signal receiver 32 can receive the signal transmitted by the signal transmitter 31; conversely, if there is an obstruction in the positioning hole 33, the signal transmission path between the signal transmitter 31 and the signal receiver 32 is interrupted, and the signal receiver 32 cannot receive the signal transmitted by the signal transmitter 31. The signal receivers of both positioning sensors are connected to the controller. The straight line containing the two positioning sensors 30 passes through the center of the rotating part 11. Figure 5 The left-center positioning sensor 30 is the positioning detection point where the rotating part 11 begins to rotate; that is, under normal conditions, the positioning terminal 121 is located at... Figure 5 The left positioning sensor's signal receiver 32 is located inside the positioning hole, preventing it from receiving signals from the left positioning sensor's transmitter. When the rotating part 11 begins to rotate, it moves the positioning terminal 121 out of the left positioning sensor's positioning hole, allowing the left positioning sensor's signal receiver 32 to receive signals from the left positioning sensor's transmitter 31. The left positioning sensor's signal receiver 32 is connected to the controller. When it receives a signal from the transmitter, it indicates that the rotating part 11 has started to rotate, moving the positioning terminal 121 out of the positioning hole 33. When the rotating part 11 rotates 180 degrees, it moves the positioning terminal 121 into the right positioning sensor's positioning hole, preventing the right positioning sensor's signal receiver from receiving signals from the right positioning sensor's transmitter. Since the right positioning sensor's signal receiver is connected to the controller, when the right positioning sensor's signal receiver no longer receives signals from the transmitter, the controller can stop the rotating part 11 from rotating. Figure 5 This application merely illustrates one specific embodiment of the invention. By setting the relative position between the positioning sensor and the elastic terminal in the non-activated state, the angle of rotation of the rotating part 11 around the normal passing through the center point of its upper surface can be changed, thereby controlling the direction of the transport object placed on the upper surface of the rotating part 11.
