Description

Technical Field

[0001] This utility model belongs to the field of storage cabinet technology, and specifically relates to an automatic anti-pinch door device for a rotating cabinet. Background Technology

[0002] Rotary cabinets, as space-efficient storage devices, are increasingly used in various scenarios for storing and distributing items. A rotary cabinet typically consists of a rotating mechanism and a retrieval slot. The rotating mechanism transports designated items to the retrieval slot for users to access or store. In current technology, the retrieval slot of rotary dispensing devices is usually closed manually. In high-frequency use scenarios, manually opening and closing the door reduces the efficiency of the device, is inconvenient to operate, and poses a significant safety hazard if the user's hands or items are not completely removed from the retrieval slot area during the closing process, potentially leading to pinching injuries or damage to items.

[0003] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing rotating cabinets have poor convenience for picking up goods and high safety hazards.

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic anti-pinch door device for a rotating cabinet. The automatic anti-pinch door device includes a door opening and closing mechanism and an anti-pinch door mechanism. The door opening and closing mechanism includes a support frame installed on the loading port, a first guide rail installed on the support frame, a door panel slidably disposed on the first guide rail, and a displacement driver installed on the support frame and connected to the door panel. The anti-pinch door mechanism includes a guide assembly installed on the door panel, an anti-pinch block slidably disposed on the guide assembly, a sensing plate installed on the anti-pinch block, and a sensor installed on the door panel. The guide assembly is used to guide the anti-pinch block to drive the sensing plate to extend into the sensing area of ​​the sensor when the anti-pinch block is blocked. The sensor triggers the displacement driver to drive the door panel to move along the length extension direction of the first guide rail to perform the door opening action.

[0006] Optionally, the anti-pinch door mechanism further includes a limiting member fixed to the door panel. The limiting member has a limiting post, and the limiting post is partially inserted through the anti-pinch block. An elastic member is sleeved on the limiting post, and the elastic member is used to reset the anti-pinch block when there is no obstruction force.

[0007] Optionally, the displacement actuator includes a drive unit fixed to the support frame, a transmission component fixed to the door panel, and a lead screw. One end of the lead screw is connected to the drive unit, and the other end of the lead screw passes through the transmission component and is threadedly connected to the transmission component.

[0008] Optionally, the transmission component includes an adapter seat having a first through hole and fixed to the door panel, and a movable component threadedly connected to the lead screw. The movable component passes through the first through hole and is fixedly connected to the adapter seat. The adapter seat is used to push and pull the door panel to move along the first guide rail.

[0009] Optionally, the door opening and closing mechanism further includes a support base having a second through hole and fixed to the support frame, wherein the other end of the lead screw passes through the first through hole and is rotatably disposed in the second through hole.

[0010] Optionally, the door opening and closing mechanism further includes a second guide rail mounted on the support frame. The second guide rail is arranged opposite to and parallel to the first guide rail, and the door panel is slidably disposed on the second guide rail.

[0011] Optionally, the automatic anti-pinch door device further includes an intelligent detection mechanism, which includes a top plate installed in the retrieval port and a side plate connected to the top plate and having an inlet / outlet slot, as well as a goods presence / absence detection component. The inlet / outlet slot is connected to the retrieval port to form an inlet / outlet channel. The goods presence / absence detection component is set on the top plate and located in the inlet / outlet channel. The goods presence / absence detection component is used to detect whether there are goods in the inlet / outlet channel.

[0012] Optionally, the intelligent detection mechanism further includes a barcode scanning component for reading barcode information on goods, the barcode scanning component being disposed on the top plate and located within the inlet / outlet channel.

[0013] Optionally, the intelligent detection mechanism further includes a cargo height limit detection component for real-time detection of whether the height of the cargo exceeds the safe height.

The light curtain detection component is installed on the side panel and located at the pickup opening.

[0015] Beneficial effects: This utility model provides an automatic anti-pinch door device for a rotating cabinet. In the door opening and closing mechanism, a support frame is installed at the retrieval opening, a first guide rail is mounted on the support frame, and a door panel is slidably mounted on the first guide rail. A displacement driver is mounted on the support frame and connected to the door panel. In the automatic anti-pinch door mechanism, a guide assembly is mounted on the door panel, an anti-pinch block is slidably mounted on the guide assembly, a sensor plate is mounted on the anti-pinch block, and a sensor is mounted on the door panel. When the anti-pinch block is obstructed, the guide assembly guides the anti-pinch block to move the sensor plate to contact the sensor. The sensor triggers the displacement driver to drive the door panel to move along the length of the first guide rail to perform the opening action. Thus, when the rotating cabinet door panel performs the closing action along the first guide rail under the drive of the displacement driver, if there is an obstacle such as a user's hand or an item between the door panel and the retrieval opening, the obstacle will exert an obstructing force on the anti-pinch block. Under the action of the obstructing force, the anti-pinch block is displaced under the guidance of the guide assembly, which will move the sensor plate mounted on the anti-pinch block to contact the sensor on the door panel. When the sensor plate comes into contact with the sensor, the sensor is triggered and transmits a signal to the displacement actuator, causing the displacement actuator to change its direction of movement and drive the door panel to perform an opening action along the length of the first guide rail. This achieves the technical effect of improving the convenience of opening and closing the door while enhancing safety. Attached Figure Description

Figure 6 This is a structural schematic diagram of the intelligent detection mechanism in an automatic anti-pinch door device for a rotating cabinet provided in an embodiment of this utility model. Figure 7This is a schematic diagram of the structure of the retrieval port in an automatic anti-pinch door device for a rotating cabinet according to an embodiment of the present invention. The automatic anti-pinch door device for a rotating cabinet according to an embodiment of the present invention includes a door opening / closing mechanism 1 and an anti-pinch door mechanism 2. The door opening / closing mechanism 1 includes a support frame 11, a first guide rail 12, a door panel 13, and a displacement driver 14. The support frame 11 is installed on the retrieval port 41, the first guide rail 12 is installed on the support frame 11, the door panel 13 is slidably disposed on the first guide rail 12, and the displacement driver 14 is installed on the support frame 11 and connected to the door panel 13. The anti-pinch door mechanism 2 includes a guide assembly 21, an anti-pinch block 22, a sensing plate 23, and a sensor 24. The guide assembly 21 is mounted on the door panel 13. The anti-pinch block 22 is slidably disposed on the guide assembly 21. The sensing plate 23 is mounted on the anti-pinch block 22. The sensor 24 is mounted on the door panel 13. The guide assembly 21 is used to guide the anti-pinch block 22 to drive the sensing plate 23 into the sensing area of ​​the sensor 24 when the anti-pinch block 22 is blocked. The sensor 24 triggers the displacement driver 14 to drive the door panel 13 to move along the length extension direction of the first guide rail 12 to perform the door opening action.

[0030] The guide assembly 21 can be a cross roller guide rail mounted on the door panel 13, which guides the linear movement of the anti-pinch block 22. The anti-pinch block 22 is slidably mounted on the guide assembly 21 and can move along a specific direction under the guidance of the guide assembly 21, such as moving towards or away from the sensor 23 and sensor 24. The sensor 23 is mounted on the anti-pinch block 22, and the sensor 24 is fixedly mounted on the door panel 13, located on the movement path of the sensor 23. Alternatively, the guide assembly 21 can adopt an inclined guide groove structure, which is fixedly mounted on the edge of the door panel 13. When the anti-pinch block 22 is subjected to a horizontal obstruction force, it can generate an inward displacement component, i.e., towards the inside of the door panel 13, allowing the anti-pinch block 22 to move under the guidance of the guide assembly 21. The anti-pinch block 22 can also be made of an elastic material, which can reduce the impact force when in contact with obstacles and increase the contact area through its deformation capacity. The sensing element 23 can be made of conductive material. The position of the sensor 24 corresponds to the moving end point of the sensing element 23. That is, when the anti-pinch block 22 moves into position along the guide assembly 21 under the action of the blocking force, the sensing element 23 will extend into the sensing range of the sensor 24, thereby detecting the abnormal state of the picking port. The guide assembly 21 ensures that when the anti-pinch block 22 is blocked by an obstacle, the anti-pinch block 22 will move along the preset direction of the guide assembly 21, driving the sensing element 23 to move closer to the sensor 24 until the sensor 24 is triggered by the sensing element 23. When the sensor 24 is triggered, the rotating cabinet outputs a signal to the control system of the displacement driver 14, causing the displacement driver 14 to change its direction of movement, such as rotating in the opposite direction to drive the door panel 13 to move along the length extension direction of the first guide rail 12 to perform the door opening action.

[0031] The support frame 11 is installed around the loading port 41 of the rotating cabinet. The first guide rail 12 can be a linear guide rail, installed at the lower part of the support frame 11, allowing the door panel 13 to slide smoothly. The door panel 13 can be equipped with sliders or pulleys that cooperate with the first guide rail 12, enabling the door panel 13 to slide smoothly along the first guide rail 12. An anti-pinch block 22 is installed on one edge of the door panel 13. The anti-pinch block 22 is located in the area between the door panel 13 and the loading port 41 where pinching is likely to occur. Figure 3 The central anti-pinch block 22 is located between the left side of the support frame 11 and the left edge of the door panel 13.

[0032] During operation, when the door panel 13 closes under the drive of the displacement driver 14, if an obstacle exists between the door panel 13 and the loading port 41, the obstacle will exert a blocking force on the anti-pinch block 22. At this time, the anti-pinch block 22 will move along the path set by the guide assembly 21, causing the sensing plate 23 to move closer to the sensor 24 until the sensing plate 23 extends into the sensing area of ​​the sensor 24. At this point, the sensor 24 is triggered and sends a signal to the control circuit of the displacement driver 14. The control circuit will immediately change the driving rotation direction of the displacement driver 14, causing the door panel 13 to open, thus preventing injury to obstacles such as the user's hand or objects. Alternatively, a time delay function can be set in the control circuit, allowing the door panel 13 to attempt to close again after a preset time after opening. If the obstacle has been removed, the closing action is completed; if the obstacle still exists, the anti-pinch function is triggered again, repeating this cycle until the door is successfully closed or the preset number of attempts is reached.

[0033] In this embodiment, in the door opening and closing mechanism 1, the support frame 11 is installed on the loading port 41, the first guide rail 12 is installed on the support frame 11, the door panel 13 is slidably disposed on the first guide rail 12, the displacement driver 14 is installed on the support frame 11 and connected to the door panel 13, in the automatic anti-pinch door mechanism 2, the guide component 21 is installed on the door panel 13, the anti-pinch block 22 is slidably disposed on the guide component 21, the sensing plate 23 is installed on the anti-pinch block 22, and the sensor 24 is installed on the door panel 13. When the anti-pinch block 22 is blocked, the guide component 21 guides the anti-pinch block 22 to drive the sensing plate 23 to trigger the sensor 24. The sensor 24 further triggers the displacement driver 14 to drive the door panel 13 to move along the length extension direction of the first guide rail 12 to perform the door opening action. When the rotating cabinet door 13 closes along the first guide rail 12 under the drive of the displacement actuator 14, if there is an obstacle such as a user's hand or an item between the door 13 and the retrieval opening 41, the obstacle will exert a blocking force on the anti-pinch block 22. Under the action of the blocking force, the anti-pinch block 22 is displaced under the guidance of the guide assembly 21, which will move the sensor 23 installed on the anti-pinch block 22 to the sensing area of ​​the sensor 24 on the door 13. The sensor 24 is triggered and transmits the emitted signal to the displacement actuator 14, causing the displacement actuator 14 to change its direction of movement and drive the door 13 to open along the length extension direction of the first guide rail 12. This achieves the technical effect of improving the convenience of opening and closing the rotating cabinet door while improving safety.

[0034] As one embodiment, the anti-pinch door mechanism 2 of the automatic anti-pinch door device for a rotating cabinet provided in this utility model embodiment further includes a limiting member 25 and an elastic member 26. The limiting member 25 is fixed on the door panel 13 and has a limiting post (not shown in the figure). The limiting post extends toward the anti-pinch block 22 and partially passes through the anti-pinch block 22. That is, there is a gap between the part of the limiting member from which the limiting post extends and the anti-pinch block. An elastic member is sleeved on the limiting post, and the expansion and contraction space of the elastic member is within the aforementioned gap. The elastic member 26 is used to reset the anti-pinch block 22 when there is no obstruction force. The limiting member 25 is fixedly installed on the door panel 13 and is arranged opposite to the anti-pinch block 22. One end of the elastic member 26 abuts against the anti-pinch block 22, and the other end abuts against the limiting member 25. The elastic element 26 may include a spring. When the door panel 13 performs the closing action, if there is no obstacle between the door panel 13 and the loading slot 41, the anti-pinch block 22 remains in its initial position under the action of the elastic element 26, and the sensing plate 23 and the sensor 24 remain separated in the horizontal direction, allowing the door panel 13 to complete the closing action smoothly. If there is an obstacle between the door panel 13 and the loading slot 41, the obstacle will exert a blocking force on the anti-pinch block 22, causing the anti-pinch block 22 to overcome the elastic force of the elastic element 26 and move along the guide assembly 21, driving the sensing plate 23 to extend into the sensing area of ​​the sensor 24, triggering the sensor 24, causing the displacement driver 14 to change its direction of movement, and driving the door panel 13 to perform the opening action. When the obstacle is removed, the anti-pinch block 22 is no longer subject to the blocking force. At this time, the elastic force of the elastic element 26 will pull or push the anti-pinch block 22 back to its initial position, causing the sensing plate 23 and the sensor 24 to separate in the horizontal direction, restoring the state where the closing action can be performed again. By setting the limiting element 25 and the elastic element 26, the anti-pinch block 22 can be automatically reset. The anti-pinch door mechanism 2 can automatically return to the initial state after each trigger without manual intervention, which is conducive to improving the degree of automation and ease of use. At the same time, the elastic element 26 will also give the anti-pinch block 22 a certain pre-tightening force, which can realize the reliable sensing between the sensing plate 23 and the sensor 24, and improve the sensitivity and reliability of the anti-pinch function.

[0035] In some embodiments, the displacement actuator 14 in the automatic anti-pinch door device of a rotating cabinet provided by this utility model includes a drive unit 141, a transmission component 142, and a lead screw 143. The drive unit 141 is fixed on the support frame 11, the transmission component 142 is fixed on the door panel 13, one end of the lead screw 143 is connected to the drive unit 141, and the other end of the lead screw 143 passes through the transmission component 142 and is threadedly connected to the transmission component 142. The drive unit 141 may include a motor or a cylinder, preferably a stepper motor or a servo motor, and is fixedly mounted on the support frame 11. The output shaft of the motor is connected to one end of the lead screw 143, and the rotation direction of the lead screw 143 is controlled by the forward and reverse rotation of the motor. The lead screw 143 may be a threaded rod, and the other end of the lead screw 143 passes through the transmission component 142 and is threadedly connected to the transmission component 142. The transmission component 142 is fixedly installed on the door panel 13. When the lead screw 143 rotates, due to the threaded connection between the transmission component 142 and the lead screw 143, the transmission component 142 moves along the axial direction of the lead screw 143, thereby driving the door panel 13 to slide along the first guide rail 12, realizing the opening or closing action. When the sensor 24 is triggered, it sends a signal to the drive unit 141. After receiving the signal, the drive unit 141 changes the rotation direction of the motor, causing the lead screw 143 to rotate in the opposite direction, driving the door panel 13 to perform the opening action. The threaded connection between the lead screw 143 and the transmission component 142 converts the rotational motion of the motor into the linear motion of the door panel 13, realizing an effective conversion of motion mode. At the same time, the lead screw 143 transmission has a self-locking function. When the motor stops working, the door panel 13 can remain in the current position without moving, and can also quickly respond to the trigger signal of the sensor 24 to promptly execute the opening action, effectively preventing the occurrence of pinching accidents and improving stability and safety.

[0036] In some embodiments, the transmission component 142 of the automatic anti-pinch door device for a rotating cabinet provided by this utility model includes an adapter 1421 and a moving component 1422. The moving component 1422 includes a nut. The adapter 1421 has a first through hole 14211 and is fixed to the door panel 13. The moving component 1422 is threadedly connected to a lead screw 143. The moving component 1422 passes through the first through hole 14211 and is fixedly connected to the adapter 1421. The adapter 1421 is used to push and pull the door panel along the first guide rail.

[0037] The adapter 1421 can be fixed to the door panel 13 by screws or welding, making the adapter 1421 and the door panel 13 an integral unit. The moving part 1422 is threadedly connected to the lead screw 143. The moving part 1422 passes through the first through hole 14211 on the adapter 1421 and can be fixedly connected to the adapter 1421 by welding. When the lead screw 143 rotates, because the moving part 1422 is threadedly connected to the lead screw 143 and is fixed to the adapter 1421 and cannot rotate, the moving part 1422 will move along the axial direction of the lead screw 143, driving the adapter 1421 to move. The adapter 1421 pushes or pulls the connected door panel 13 to move together with the first guide rail 12 through the slider connected to the door panel, realizing the opening or closing action of the door.

[0038] In some embodiments, the automatic anti-pinch door device for a rotating cabinet provided by this utility model further includes a support base 16. The support base 16 has a second through hole 14231 and is fixed to the support frame 11. The other end of the lead screw 143 passes through the first through hole 14211 and is rotatably disposed in the second through hole 14231. The support base 16 can be fixedly installed on the support frame 11 by screws or welding. The support base 16 can stably support the lead screw 143. In addition, a bearing can be provided in the second through hole 14231. The other end of the lead screw 143 passes through the first through hole 14211 of the adapter 1421 and is inserted into the second through hole 14231 of the support base 16, and is rotatably connected by the bearing. That is, one end of the lead screw 143 is supported by the drive part 141, and the other end is supported by the support base 16, which improves the stability of the lead screw 143, reduces the vibration and wobble of the lead screw 143 when rotating at high speed, and helps to improve the rotation accuracy and running smoothness of the lead screw 143. Meanwhile, the support base 16 can also limit and protect the lead screw 143, preventing axial movement of the lead screw 143 during operation and improving the reliability and durability of the transmission process. The bearings on the support base 16 can reduce the friction between the lead screw 143 and the support base 16, reduce operating resistance and energy consumption, improve transmission efficiency, and make the operation of the door opening and closing mechanism 1 more stable and reliable, extending its service life.

[0039] In some embodiments, the automatic anti-pinch door device for a rotating cabinet provided by this utility model further includes a second guide rail 15. The second guide rail 15 is mounted on the support frame 11 and is arranged opposite to the first guide rail 12. The second guide rail 15 and the first guide rail 12 are parallel to each other. The door panel 13 is slidably mounted on the second guide rail 15. Through the combined action of the first guide rail 12 and the second guide rail 15, the tilting, twisting and shaking of the door panel 13 during the movement is effectively prevented, making the opening and closing action of the door panel 13 more stable. At the same time, the stable movement of the door panel 13 also enables the anti-pinch door mechanism 2 to accurately respond to the obstruction of obstacles. When the anti-pinch block 22 is obstructed, the sensor 24 can be reliably triggered, and the displacement driver 14 can change the direction of movement in time, driving the door panel 13 to perform the opening action, effectively preventing the occurrence of pinching accidents, and achieving the technical effect of improving the convenience and safety of opening and closing the door. Furthermore, the first guide rail 12 and the second guide rail 15 can also improve the load-bearing capacity and stability of the door panel 13. For example, when the door panel 13 is large or heavy, a single guide rail cannot provide sufficient support, which can easily lead to deformation of the door panel 13 or accelerated wear of the guide rail. By distributing the weight of the door panel 13 onto the first guide rail 12 and the second guide rail 15, the burden on a single guide rail is reduced, which helps to extend the service life of the guide rail. In addition, when the door panel 13 is subjected to external force interference, such as when the user pushes or pulls the door panel 13, the first guide rail 12 and the second guide rail 15 can provide stronger restraint, so that the door panel 13 is kept on the predetermined movement trajectory, reducing movement deviation and jamming, which helps to improve anti-interference ability.

[0040] In some embodiments, the automatic anti-pinch door device for a rotating cabinet provided by this utility model further includes an intelligent detection mechanism 3. The intelligent detection mechanism 3 includes a top plate 31, a side plate 32, and a goods presence / absence detection component 33. The top plate 31 is installed inside the retrieval port 41, and the side plate 32 is perpendicularly connected to the top plate 31. The side plate 32 has an inlet / outlet slot 321, which communicates with the retrieval port 41 to form an inlet / outlet channel. The goods presence / absence detection component 33 is used to detect whether there are goods in the inlet / outlet channel. The goods presence / absence detection component 33 is disposed on the top plate 31 and is located inside the inlet / outlet channel. The top plate 31 is installed inside and above the retrieval port 41, and the side plate 32 is connected to the top plate 31. The side plate 32 has an inlet / outlet slot 321, which communicates with the retrieval port 41 to form a channel for goods to enter and exit, i.e., an inlet / outlet channel. A goods presence / absence detection component 33 is installed on the top plate 31, located within the inlet / outlet channel, to detect the presence of goods within the channel. The component 33 may include an infrared sensor, a photoelectric sensor, or an ultrasonic sensor. When goods enter or leave the channel, the component 33 detects their presence or absence and transmits the detection signal to the control system. Through the component 33, the control system can monitor the status within the channel in real time, determining whether the user has completed the retrieval or storage operation. When a user retrieves goods from the rotating cabinet, the component 33 detects that the goods have passed through the channel and sends a signal after the goods have completely left, indicating that the retrieval operation is complete. At this time, the displacement driver 14 is automatically triggered, driving the door panel 13 to close, eliminating the need for manual operation and improving ease of use. Similarly, when a user stores goods into the rotating cabinet, the goods presence detection component 33 will detect that the goods have entered the inlet / outlet channel and send a signal after the goods have fully entered, indicating that the storage operation is complete. At this time, the control system can also automatically trigger the door closing operation. In addition, if the goods presence detection component 33 detects that there are still goods or user hands in the inlet / outlet channel during the closing process, the closing operation will be paused and the door will continue to close after the channel is cleared, which helps to improve safety and enhance the convenience of opening and closing the door.

[0041] In some embodiments, the intelligent detection mechanism 3 in the automatic anti-pinch door device of a rotating cabinet provided by this utility model further includes a barcode scanning component 34. The barcode scanning component 34 is used to read barcode information on the goods. The barcode scanning component 34 is mounted on the top plate 31 and located inside the inlet / outlet channel. The barcode scanning component 34 may include a barcode scanner or a QR code scanner. Installed on the top plate 31 and located inside the inlet / outlet channel, it can automatically read barcode or label information on goods passing through the channel. When goods pass through the inlet / outlet channel, the barcode scanning component 34 automatically scans and reads the barcode information on the goods, such as obtaining the goods' number, name, and specifications, and transmits this information to the central control unit. Based on the scanned barcode information, it can be determined whether the current operation is a retrieval or a storage operation. For example, if the system database records that the item has already been stored in the rotating cabinet, and it is now scanned and passing through the inbound / outbound channel, it is determined to be a retrieval operation. Conversely, if the item was not previously recorded or has already been retrieved, and it is now scanned, it is determined to be a storage operation. This enables accurate identification and recording of the entry and exit of goods, reduces manual operation and recording steps, and improves ease of use.

[0042] In some embodiments, the intelligent detection mechanism 3 in the automatic anti-pinch door device of the rotating cabinet provided by this utility model further includes a goods height limit detection component 35. The goods height limit detection component 35 is used to detect in real time whether the height of the goods exceeds the safe height. The goods height limit detection component 35 is mounted on the side plate 32 and located at the inlet / outlet slot 321. The goods height limit detection component 35 may include a laser rangefinder, an ultrasonic sensor, or a photoelectric sensor array. Mounted on the side plate 32 and located at the inlet / outlet slot 321, it can detect the height of goods passing through the inlet / outlet slot 321 in real time. During the use of the rotating cabinet, if the height of goods taken out or stored by the user exceeds the safety limit, it is easy to collide with the internal structure of the rotating cabinet or other goods, leading to damage to the goods or system malfunction. When goods pass through the inlet / outlet slot 321, the goods height limit detection component 35 measures the height of the goods in real time and compares the measurement result with a preset safe height. If the height of goods exceeds the safety limit, an alarm will be immediately triggered, reminding the user to adjust the goods' posture or replace them with suitable goods to prevent excessively tall goods from entering the rotating cabinet. Simultaneously, if goods exceeding the height limit are detected passing through the inlet / outlet slot 321, the closing operation of the door panel 13 will be paused until the user has finished handling the situation before continuing to close the door, preventing damage to goods or system malfunctions caused by forced closure. By positioning the goods height limit detection component 35 at the inlet / outlet slot 321, height detection can be performed before goods enter the rotating cabinet, allowing for timely detection and handling of height exceeding limits. This effectively prevents malfunctions caused by unsuitable goods height, protects the safety of goods and equipment, and improves reliability.

[0043] In some embodiments, the intelligent detection mechanism 3 in the automatic anti-pinch door device of a rotating cabinet provided by this utility model further includes a light curtain detection component 36. The light curtain detection component 36 is used to detect whether there is an object at the retrieval opening 41 before the door panel 13 closes. The light curtain detection component 36 is mounted on the side panel 32 and located at the retrieval opening 41. The light curtain detection component 36 may include a transmitter and a receiver to form a light curtain composed of multiple beams of infrared light. The light curtain detection component 36 is mounted on the side panel 32 and located at the retrieval opening 41, and can detect objects passing through the light curtain. Before the door panel 13 closes, the light curtain detection component 36 forms a dense network of light in the area of ​​the retrieval opening 41. If there is an object, such as a user's hand, or goods located at the retrieval opening 41, it will block part of the light. The light curtain detection component 36 will immediately detect the above changes and send a signal. If there is an obstacle, the closing operation of the door panel 13 will be paused, or if the door panel 13 has already started to close, the direction of movement will be immediately changed to perform an opening action to prevent the obstacle from being pinched. The light curtain detection component 36 can cover the entire pickup area 41, not just the edge of the door panel 13, enabling it to detect obstacles over a wider range and providing more comprehensive security. Additionally, it can determine whether a user is picking up or storing goods based on the location and duration of light curtain obstruction, allowing for delayed door closing to improve user experience.

[0044] In some embodiments, the automatic anti-pinch door device for a rotating cabinet provided by this utility model further includes a cabinet body 4, with a retrieval port 41 disposed on the cabinet body 4. The retrieval port 41 is located on the front side of the cabinet body 4, serving as a channel for users to interact with items within the rotating cabinet. The cabinet body 4 enables the safe storage of goods inside. A support frame 11 is installed around the retrieval port 41 to support the door opening and closing mechanism 1. When a user retrieves or stores goods from the rotating cabinet, they need to operate through the retrieval port 41. At this time, the door panel 13 slides along the first guide rail 12 under the drive of the displacement driver 14, controlling the opening and closing of the retrieval port 41. When the door panel 13 performs a closing action, if the user's hand or items are located between the door panel 13 and the retrieval port 41, an obstructing force will be applied to the anti-pinch block 22. The anti-pinch block 22 is displaced under the guidance of the guide component 21, causing the sensing plate 23 to extend into the sensing area of ​​the sensor 24, triggering the sensor 24, which causes the displacement driver 14 to change its direction of movement, driving the door panel 13 to perform the opening action, thus preventing pinching accidents. A shelf 8 can also be installed inside the cabinet 4, which can be used to transport goods to the retrieval port 41. The shelf 8 has multiple shelf units, each with multiple storage locations for storing different types of goods. The shelf 8 is connected to the control unit via a motor drive system, and can rotate according to control commands to transport the specified goods to the retrieval port 41. For example, the shelf 8 may include a vertically set central axis, with multiple shelf units arranged radially around the central axis. Each shelf unit can rotate independently or as a whole, achieving flexible goods transport. After the user selects the desired goods through the human-machine interface 5, the user will control the shelf 8 to rotate, transporting the target goods to the retrieval port 41. When the goods arrive at the pickup opening 41, the displacement driver 14 will be controlled to drive the door panel 13 to slide along the first guide rail 12 to perform the door opening action, so that the user can take out the goods.

[0045] In some embodiments, the automatic anti-pinch door device for a rotating cabinet provided by this utility model further includes a human-machine interface 5, which is disposed on the cabinet body 4. The human-machine interface 5 can be installed on the front side of the cabinet body 4 at a height convenient for user operation. The human-machine interface 5 may include a touch screen display or an LCD screen with display function combined with buttons. The human-machine interface 5 is connected to the control unit via a data cable and can display system status information and receive user operation commands. Through the human-machine interface 5, the user can intuitively understand the working status of the rotating cabinet, such as the opening and closing status of the door panel 13. At the same time, the user can also issue opening or closing operation commands through the human-machine interface 5 to control the movement of the door panel 13. In practical applications, the human-machine interface 5 can display various information and provide various functions, such as displaying the current status of the door panel 13, i.e., open, closed, or in motion; displaying the working status of the anti-pinch door mechanism 2, i.e., normal or triggered; providing opening and closing operation buttons; displaying system fault diagnosis information; providing user authentication functions, such as password input, card swiping, or QR code login; and displaying operation guidance and help information. When a user needs to retrieve goods from the rotating cabinet, they can authenticate their identity through the human-machine interface 5. After successful authentication, the system automatically triggers the displacement actuator 14, which drives the door panel 13 to open. After retrieving the goods, the user can close the door panel 13 using the closing button on the human-machine interface 5. If an obstacle exists between the door panel 13 and the retrieval opening 41 during the closing process, the anti-pinch block 22 will be obstructed, causing the sensor 23 to contact the sensor 24, triggering the displacement actuator 14 to change its direction of movement and open the door. Simultaneously, the human-machine interface 5 will display a warning message indicating that the anti-pinch protection has been triggered, reminding the user to be careful. Additionally, after detecting that the user has completed the retrieval operation, the human-machine interface 5 can automatically prompt the user whether to close the door panel 13, or automatically close the door after user confirmation. The human-machine interface 5 enables effective communication and interaction with the user, allowing for more convenient operation of the rotating cabinet. Furthermore, the intuitive status display and operation prompts enhance the convenience and safety of opening and closing the door.

[0046] In some embodiments, the automatic anti-pinch door device for a rotating cabinet provided by this utility model also includes a retrieval indicator light 6. The retrieval indicator light 6 is installed on the cabinet body 4 and is located near the retrieval opening 41 for easy observation by the user. The retrieval indicator light 6 may include an LED light capable of emitting different colored light signals, such as red, green, and yellow. The retrieval indicator light 6 is connected to the system's control unit via a wire, and the control unit controls its on / off state and color changes, allowing the user to clearly understand the current status of the rotating cabinet and the operations that can be performed. For example, different colored lights can represent different system states. When the green light is on, it indicates that the door panel 13 is fully open, and the user can safely retrieve or store goods. When the red light is on, it indicates that the door panel 13 is closing or has already closed, and the user should not retrieve or store goods. When the yellow light is on, it indicates that the system is processing, such as the door panel 13 being opened, and the user needs to wait. When the light flashes, it indicates that the system has malfunctioned, such as the anti-pinch door mechanism 2 being triggered, and the user needs to pay attention. When a user issues an open command through the human-machine interface 5, the displacement actuator 14 drives the door panel 13 to open. Simultaneously, the retrieval indicator light 6 will turn yellow, indicating that the door panel 13 is opening. Once the door panel 13 is fully open, the retrieval indicator light 6 turns green, prompting the user to retrieve or store goods. After the user completes the operation, they can issue a close command through the human-machine interface 5, and the retrieval indicator light 6 will turn yellow, indicating that the door panel 13 is closing. If, during the closing process, the anti-pinch block 22 is obstructed, triggering the anti-pinch door mechanism 2, the displacement actuator 14 will change its direction of movement, driving the door panel 13 to reopen. At this time, the retrieval indicator light 6 will flash yellow, reminding the user to be careful. Once the door panel 13 is fully closed, the retrieval indicator light 6 turns red, indicating that the retrieval opening 41 is closed, and the user should not attempt any further operation. The retrieval indicator light 6 provides intuitive visual feedback, allowing users to clearly understand the working status of the rotating cabinet, avoiding misoperation due to unclear status, and improving user-friendliness and safety.

[0047] In some embodiments, the automatic anti-pinch door device for a rotating cabinet provided by this utility model further includes a button assembly 7. The button assembly 7 is disposed on the cabinet body 4, close to the human-machine interface 5, for easy user operation. The button assembly 7 may include multiple physical buttons, such as an open button, a close button, a confirm button, and a cancel button. The button assembly 7 is connected to the system's control unit via wires, and can convert the user's button operations into electrical signals and transmit them to the control unit. For example, when the human-machine interface 5 malfunctions, the user can continue to operate the rotating cabinet through the button assembly 7. Or, for users who are not accustomed to using touch screens, physical buttons can provide a more intuitive and familiar operating method. In specific environments, such as when the user is wearing gloves, the touch screen may not respond properly, but the physical buttons can still be used normally. In addition, for critical operations such as emergency stop, operating the physical buttons can improve reliability and safety. Specifically, the user can press the open button to trigger the displacement driver 14 to drive the door panel 13 to perform the opening action. When the door panel 13 is fully opened, the retrieval indicator light 6 turns green, prompting the user to perform a retrieval or storage operation. After the user completes the operation, pressing the close button triggers the door panel 13 to close. If the anti-pinch block 22 is obstructed during the closing process, triggering the anti-pinch door mechanism 2, the displacement driver 14 will change its direction of movement, driving the door panel 13 to reopen. At this time, the user can remove the obstacle and then press the close button again to try to close the door panel 13. Through the combined use of the button assembly 7 and the human-machine interface 5, users are provided with multiple operation options, improving adaptability and reliability.
