[0036] The workstation with a safety protection opening and closing structure described in this utility model will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, this explanation and description do not constitute an undue limitation on the technical solution of this utility model.
[0037] Currently, the handling and processing of various workpieces are completed within workstations. However, current workstations still have many shortcomings. For example, traditional material handling equipment typically uses a sequential pick-and-place method, lacking automated reciprocating conveying capabilities, resulting in significant manual intervention and low production efficiency. Furthermore, during operation, existing equipment poses considerable safety hazards due to operators being prone to accidental contact with the equipment or entering the workstation unintentionally.
[0038] Therefore, in one embodiment of this utility model, it is desired to provide a workstation with a safety protection opening and closing structure, which has a simple structure, is easy to use, has high material conveying efficiency, and also has a high level of safety protection performance, thereby greatly improving the safety of the workstation and the efficiency of production operation.
[0039] Figure 1 The diagram shows a structural schematic of a workstation with a safety protection opening and closing structure according to one embodiment of the present invention.
[0040] Figure 2 A schematic diagram of one embodiment of the workstation with the safety protection opening and closing structure described in this utility model is shown from a top-down perspective.
[0041] like Figure 1 and Figure 2 As shown, in some embodiments, a workstation with a safety protection opening and closing structure may include: a main frame 100, which has a processing area P, and a processing device 500 is provided in the processing area for processing and handling materials.
[0042] In addition, the workstation also includes at least a first opening / closing door 200 and a second opening / closing door 300 disposed on the main frame. The first opening / closing door 200 is used to separate the workstation from the external environment E, thereby forming an internal space relatively independent of the external environment. A material picking area Q is formed between the first opening / closing door 200 and the second opening / closing door. The second opening / closing door 300 is used to separate the material picking area Q from the processing area P. A material conveying device 400 disposed within the main frame 100 is capable of reciprocating along the path between the first opening / closing door and the processing area to convey materials and workpieces (workpieces refer to parts that have been processed from the materials). A control unit (not shown in the figure) is data-connected to at least the material conveying device 400, the first opening / closing door 200, and the second opening / closing door 300, respectively. The control unit controls the opening and closing of the first opening / closing door and the second opening / closing door based on the traveling position of the material conveying device 400.
[0043] With this setup, during the stage when the operator is picking up or placing materials, the first opening and closing door 200 is in the open state, and the material conveying device 400 will stay in the picking area Q, waiting for the operator to pick up or place materials. At this time, in order to ensure the safety of the operator, the second opening and closing door 300 can be in the closed state.
[0044] After the material and / or workpiece is picked up and placed, the control unit controls the first opening and closing door 200 to switch from the open state to the closed state, and the second opening and closing door 300 to switch from the closed state to the open state, so that the material conveying device 400 located in the picking area can enter the processing area P through the second opening and closing door.
[0045] When the material conveying device 400 transports the material away from the picking area, the control unit can control the second opening and closing door 300 to switch from the open state to the closed state. And when the material conveying device 400 moves to the processing station in the processing area, and during the processing stage when the material is processed into a workpiece by the processing equipment, the first opening and closing door and the second opening and closing door can always be kept in the closed state.
[0046] When the material is transported to the processing station in the processing area, the material can be picked up from the material conveying device and transferred to the processing equipment by the robot arm set in the processing area. Since the robot arm is an existing device in the field, and the improvement of this utility model is not in this respect, the robot arm will not be described in detail in this utility model.
[0047] After the workpiece is processed and the robotic arm returns it to the material conveying device, the second opening / closing door switches from the closed state to the open state. The material conveying device 400 carries the processed workpiece from the processing area P to the picking area Q. At this time, the first opening / closing door remains closed. When the material conveying device 400 leaves the processing area, the second opening / closing door closes again. Before the material conveying device reaches its position in the picking area, the first opening / closing door can remain closed to prevent operators from being impacted by the reciprocating conveyor modules. Once the material conveying device 400 has reached its position in the picking area, the first opening / closing door opens again, allowing operators to retrieve the processed workpiece and place the next batch of materials for processing.
[0048] In some more specific embodiments, during at least part of the workstation's operation, such as the material and / or workpiece loading and unloading phase, the first and second opening / closing doors 200 and 300 can be interlocked via a control unit. For example, the second door may open only after the first door is fully closed, based on an opening signal from the control unit, or the first door may open only after the second door is fully closed. This further ensures that, during the operation of the material conveying device 400 and the processing equipment 500, operators cannot enter the material handling and processing areas, and avoids the possibility of the material conveying device colliding with operators in extreme or accidental situations.
[0049] As can be seen in the above embodiment, when the material conveying device 400 needs to travel back and forth between the material picking area Q and the processing area P, the control unit needs to control the second opening and closing door to open or close so that the material conveying device 400 can pass through the second opening and closing door smoothly.
[0050] In other implementations, such as Figure 2 and Figure 3 As shown, the bottom end of the second opening / closing door 300 is provided with a clearance groove 301, so that when the second opening / closing door is in the closed state, the material conveying device can also move back and forth between the material picking area Q and the processing area P via the clearance groove 301. This arrangement allows the material conveying device to move back and forth between the material picking area Q and the processing area P without opening the second opening / closing door, thereby simplifying the control process and improving work efficiency. At the same time, the second opening / closing door 300 still provides safety protection for the operators.
[0051] In some more specific implementations, such as Figure 3 and Figure 4As shown, in some more specific embodiments, the second opening / closing door 300 may include: a second opening / closing door frame 302 disposed on the main frame; a second opening / closing door body 303 slidably connected to the second opening / closing door frame; and a second driving element 304 connected to the second opening / closing door body 303 to drive the second opening / closing door body 303 to slide relative to the second opening / closing door frame 302 in the height direction H of the main frame, so as to switch between an opening position and a closing position.
[0052] In some specific embodiments, a linear guide rail extending along the height direction H of the main frame can be provided on the second opening and closing door frame, and the second opening and closing door body 303 is slidably mounted on the second opening and closing door frame via the linear guide rail.
[0053] In some specific embodiments, the second door body 303 includes at least a transparent portion to allow operators to observe the operation inside the workstation's processing area. In some more specific embodiments, the transparent portion may comprise a door panel made of high-strength, transparent polyester fiber durable material, which effectively isolates the processing area while maintaining good transparency.
[0054] During the workpiece processing, the second door remains closed at all times, ensuring that operators cannot directly access the processing area where the dangerous automatic mechanism operates, thus effectively protecting the safety of the operators.
[0055] In some more specific implementations, such as Figure 4 As shown, the second drive element 304 can be disposed on the side of the second opening and closing door frame 302, which helps to further avoid affecting the operator's line of sight when observing the equipment in the processing area.
[0056] In some specific embodiments, the second driving element 304 includes a second driving cylinder. The driving cylinder has a compact structure and occupies little space, thus making the spatial structure more compact. In some more specific embodiments, the second driving cylinder can be a rodless cylinder, which can further avoid the problem of obstructed vision caused by rod cylinders. In addition, the speed of the rodless cylinder can be adjusted by a throttle valve, thereby further ensuring the smooth opening and closing of the second door.
[0057] In some specific implementations, the second door frame can be hinged to the main frame, so that the second door 300 can rotate around an axis parallel to the height direction of the main frame, thereby realizing the rotational opening of the second door, so that operators can enter the workstation to maintain and repair the equipment inside the workstation when necessary.
[0058] Figure 5The workstation with the safety protection opening and closing structure described in this utility model is shown from one perspective, representing the structure of the first opening and closing door in one embodiment.
[0059] like Figure 5 As shown, the first opening / closing door 200 may include: a first opening / closing door frame 201 disposed on the main frame; a first opening / closing door body 202 slidably connected to the first opening / closing door frame; and a first driving element 203 connected to the first opening / closing door body 202 to drive the first opening / closing door body 202 to slide relative to the first opening / closing door frame 201 in the height direction H of the main frame, so as to switch between the opening position and the closing position.
[0060] In some specific embodiments, a linear guide rail extending along the height direction H of the main frame can be provided on the first opening and closing door frame, and the first opening and closing door body 202 is slidably mounted on the first opening and closing door frame via the linear guide rail.
[0061] In some specific embodiments, the first door body 202 includes at least a transparent portion to allow operators to observe the operation inside the workstation's processing area. In some more specific embodiments, the transparent portion may comprise a door panel made of high-strength, transparent, durable polyester fiber material.
[0062] In some more specific implementations, such as Figure 5 As shown, the first driving element 203 can be disposed in the middle of the first opening and closing door frame 201, which is beneficial to drive the sliding of the first opening and closing door body more smoothly.
[0063] In some specific embodiments, the first driving element 203 may include a first driving cylinder. The driving cylinder has a compact structure and occupies little space, thereby making the spatial structure more compact.
[0064] In some specific implementations, the first door frame can be hinged to the main frame, so that the first door 200 can rotate around an axis parallel to the height direction of the main frame, thereby realizing the rotational opening of the first door, so that operators can enter the workstation to maintain and repair the equipment inside the workstation when necessary.
[0065] Figure 6 The workstation with the safety protection opening and closing structure described in this utility model is shown to be the structure of a material conveying device in one embodiment.
[0066] like Figure 6As shown, in some embodiments, the material conveying device 400 may include: a guide rail 401; a traveling clamp 402 disposed on the guide rail 401; and a third drive element 403 connected to the traveling clamp to drive the traveling clamp to reciprocate along the path between the first opening / closing door and the processing area.
[0067] In some more specific embodiments, the third drive element 403 may include a third drive cylinder.
[0068] In some more specific implementations, such as Figure 6 As shown, the traveling fixture 402 has at least two workpiece receiving stations (where the material to be processed R1 and the finished workpiece R2 are placed, but are obscured by the material to be processed R1 and the finished workpiece R2), which are used to place the material to be processed R1 and the finished workpiece R2, respectively. In some more specific embodiments, the operator can remove the finished workpiece R2 from one receiving station of the traveling fixture of the material conveying device, and then place the material to be processed R1 in the other receiving station of the traveling fixture to further improve the efficiency of material and / or workpiece handling.
[0069] Furthermore, in some more specific embodiments, the material conveying device 400 may include a first sensing component 601 for sensing whether material and / or workpieces are placed on the material conveying device, which is connected to the control unit. In some more specific embodiments, the first sensing component may be disposed on the traveling fixture at a position corresponding to the receiving station. The first sensing component may be a sensor, such as a photoelectric sensor, or other sensing elements known to those skilled in the art. In the material handling area, when the first sensing component senses that material is placed on the material conveying device, it may send a signal to the control unit, which, based on the signal, controls a third drive element to move the traveling fixture towards the processing area. In the processing area, when the first sensing component senses that workpieces are placed on the material conveying device, it may send a signal to the control unit, which, based on the signal, controls a third drive element to move the traveling fixture from the processing area to the material handling area.
[0070] In some embodiments, the material conveying device includes a second sensing component 602 for sensing the traveling position of the traveling fixture, which is connected to the control unit. When the second sensing component senses that the traveling fixture has reached its designated position, such as in front of a second opening / closing door, in front of a first opening / closing door in the material handling area, or at a processing station in the processing area, the second sensing component sends a signal to the control unit. Based on this signal, the control unit controls a third driving element to stop operating, thereby achieving accurate conveying of materials and / or workpieces. In some more specific embodiments, the second sensing component may include a pair of proximity switches, or other sensing elements known to those skilled in the art.
[0071] This invention achieves efficient and automated material and workpiece transport through this shuttle-transport method, reducing equipment downtime and significantly improving production efficiency.
[0072] It is understood that the control unit described in this invention can be implemented in various ways. For example, it can be implemented as hardware, software, or a combination thereof.
[0073] For example, the control unit may include one or more processors. These processors may use electronic hardware, such as, in some more specific embodiments, a microcontroller (MCU).

The welded base frame may be made of high-strength steel, providing a solid foundation support; the profile upper frame may be made of a lightweight alloy, such as aluminum alloy profiles, thus giving the main frame both good strength and lightweight advantages, facilitating installation and maintenance.
