Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, and in particular to an automatic lifting door mechanism. Background Technology

[0002] An automated production line is a form of production organization where the product manufacturing process is realized by an automated machine system. It is developed from the continuous production line. Its characteristics are: the workpiece is automatically transferred from one machine tool to another, and the machine tools automatically perform processing, loading, unloading, and inspection; workers' tasks are only to adjust, supervise, and manage the automated line, and they do not participate in direct operation; all machines operate at a uniform pace, and the production process is highly continuous.

[0003] In traditional production processes, when a process needs to be carried out in a closed space, this closed space is used as a workstation on the assembly line. The operation steps are: open the door - the assembly line sends the product into the closed space - the closed space door closes - the process is carried out inside the closed space. In this production process, the door of the closed space needs to be opened and closed extremely frequently, which makes it difficult to meet the cycle time requirements of continuous processing and assembly in automated production lines. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic lifting door mechanism that realizes the automatic lifting and closing of the sealed door during the production process, ensuring that the production process can be carried out in a closed space.

[0005] The objective of this utility model is achieved through the following technical solution: According to an embodiment of this disclosure, an automatic lifting door mechanism is provided, comprising: A substrate, wherein a door opening is provided on the substrate, and vertical guide rails are installed on both the left and right sides of the door opening; The door body is installed on the front side of the base plate. The two sides of the door body are connected to the guide rail through rollers. The upper side of the door body is connected to the cylinder through a transmission structure. The triggering mechanism includes a switch assembly and a triggering member. The switch assembly includes an upper tactile switch and a lower tactile switch disposed on a base plate on the same side of the door opening and distributed vertically. The upper and lower tactile switches have the same structure, each including a controller and a resilient contact piece.

[0008] As a preferred embodiment, the triggering component includes a housing with an opening on the side of the housing near the door; the roller is rotatably mounted on the door, and the roller surface is slidably connected to the guide rail via the opening.

[0009] As a preferred embodiment, a contact member is provided on the side of the housing away from the door body. The contact member includes a flat plate, and inclined plates are connected to the upper and lower ends of the flat plate. The end of the inclined plate away from the flat plate points obliquely towards the guide rail.

[0010] As a preferred embodiment, one end of the elastic contact is connected to the outside of the controller, and the other end of the elastic contact is equipped with a contact wheel.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: As Figures 1-4 As shown, an automatic lifting door mechanism includes: The substrate 1 has a door opening 10, and vertical guide rails 11 are installed on both the left and right sides of the door opening 10. Door 2 is mounted on the front side of base plate 1. Both sides of door 2 are slidably connected to guide rail 11 via rollers 21. The upper side of door 2 is connected to cylinder 23 via transmission structure 22. The triggering mechanism 3 includes a switch assembly 31 and a triggering member 32. The switch assembly 31 includes an upper tactile switch 311 and a lower tactile switch 312 disposed on a base plate 1 on the same side of the door opening 10 and distributed vertically. The upper tactile switch 311 and the lower tactile switch 312 have the same structure, each including a controller 313 and an elastic contact 314. The elastic contact 314 and the controller 313 are electrically connected, and the controller 313 is electrically connected to the cylinder 23. One side of the triggering member 3 is connected to the door body 2, and the other side of the triggering member 3 can touch and press the elastic contact 314 of the upper tactile switch 311 or the lower tactile switch 312.

[0019] During implementation, when the elastic contact piece is subjected to pressure, the corresponding controller generates an emergency stop signal. This signal brakes the cylinder, stopping its movement. Specifically, as the door moves upward, it contacts the elastic contact piece of the upper tactile switch, stopping the cylinder and thus halting the door's upward movement while keeping the doorway open. Conversely, as the door moves downward, it contacts the elastic contact piece of the lower tactile switch, stopping the cylinder and thus halting the door's downward movement while keeping the doorway closed.

[0020] Specifically, the transmission structure 22 includes a plurality of guide wheels 221 and a guide belt 222 connecting the guide wheels 221. One end of the guide belt 222 is connected to the output end of the cylinder 23, and the other end of the guide belt 222 is connected to the door body 2.

[0021] In practice, the guide wheel can be a sprocket, and the guide belt can be a chain. Depending on the actual situation, the door may need to be radiation-proof, so the inside of the door may be filled with lead. However, this would increase the mass of the door, and using a sprocket and chain drive system is more suitable for balancing the displacement of a large door.

[0022] During implementation, the cylinder can be placed horizontally. At least two guide wheels distributed vertically can convert the lateral displacement of the cylinder into vertical displacement, avoiding the large mass of the door body from directly pulling the cylinder in the same direction, which would lead to accelerated wear of the cylinder and thus extend the service life of the cylinder.

[0023] Specifically, the guide belt 222 is connected to the upper middle position of the door body 2 via the lifting member 223.

[0024] In this way, the lifting point is located at the midpoint of the upper side of the door, which can ensure the balance of gravity and prevent the door from tilting.

[0025] Specifically, the triggering component 32 includes a housing 320, which has an opening on the side near the door 2; the roller 21 is rotatably mounted on the door 2, and the wheel surface of the roller 21 is slidably connected to the guide rail 11 through the opening.

[0026] In this way, the door body and the guide rail are connected by a guide wheel drive, which allows the door body to tilt slightly without getting stuck.

[0027] Specifically, a contact member 321 is provided on the side of the housing 320 away from the door body 2. The contact member 321 includes a flat plate 3211. The upper and lower ends of the flat plate 3211 are connected to inclined plates 3212. The end of the inclined plate 3212 away from the flat plate 3211 points obliquely towards the guide rail 11.

[0028] Specifically, one end of the elastic contact 314 is connected to the outside of the controller 313, and the other end of the elastic contact 314 is equipped with a contact wheel 315. The contact wheel 315 rolls between the guide rail 11, the elastic contact 314 of the upper tactile switch 311 and the elastic contact 314 of the lower tactile switch 312.

[0029] Specifically, a button 316 is provided on the outside of the controller 313, and the button 316 abuts against the inside of the elastic contact piece 314.

[0030] In this embodiment, when the door passes the upper or lower tactile switch, the contact wheel moves from the guide rail through the inclined plate into the flat plate, and the elastic contact piece is gradually pressed, which in turn presses the button. The press of the button will activate the controller to send an emergency stop signal. When the contact wheel leaves the flat plate, the elastic contact piece is also released from the pressed state, and the button will also be released, thereby stopping the controller from sending the emergency stop signal.

[0031] Specifically, a first sensor 4 is installed on the surface of the substrate 1 and at a position below the doorway 2.

[0032] Specifically, the first sensor 4 is mounted on the front surface of the substrate 1.

[0033] In this embodiment, the first sensor is used to sense whether the door is nearby (i.e., whether the door is below; when the door is below, it means the doorway is closed, and vice versa). When the first sensor does not sense the door is nearby, it sends a start signal to the communication module of the first conveyor belt in front of the enclosed space. At this time, the first conveyor belt starts and delivers the product to the back of the door (i.e., inside the enclosed space).

[0034] Specifically, a second sensor 5 is mounted on the rear surface of the substrate 1.

[0035] In this embodiment, the second sensor is used to sense whether the product is behind the door. When the second sensor senses the back of the door, it sends a start signal to the communication module that controls the second conveyor belt behind the enclosed space. At this time, the second conveyor belt starts and connects to the product from the first conveyor belt to transport it to the next process.

[0036] Specifically, anti-pinch sensors 6 are installed on opposite sides of the doorway 2. When a foreign object is in the vicinity of the anti-pinch sensor 6, the sensor will lock the door to prevent pinching. In practice, the anti-pinch sensor 6 sends a signal to the communication module of the anti-pinch component, which then controls the anti-pinch component to lock the door. Specifically, the anti-pinch component may include a vertically rotatable support plate. After receiving the signal from the anti-pinch component, the communication module can control the support plate to rotate upwards to support the door 2 and prevent it from continuing to move downwards.

[0037] In addition, the anti-pinch sensor also has an alarm module. When it receives a foreign object signal from the anti-pinch sensor, the alarm module will sound an alarm.

[0038] It should be noted that the connection circuit between the elastic contact and the controller, the control circuit between the controller and the cylinder, and the control circuits of the first sensor, the second sensor, and the foreign object sensor are all conventional technical means in this field. How the specific circuits are controlled is not the content to be protected in this application and will not be described in detail here.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
