[0033] The safety protection door opening and closing device and workstation of this utility model will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, such explanation and description do not constitute an undue limitation on the technical solution of this utility model.

[0034] Current workstations feature a fixed protective cover that surrounds the workbench, creating an enclosed space. While this type of cover provides stable protection, it can cause some inconvenience during operation and maintenance, as it may need to be removed for internal repairs. In addition, portable protective covers are available, which are convenient to use but offer limited protection, especially for large equipment.

[0035] To address the aforementioned technical problems, this utility model provides a safety protection door opening and closing device in one embodiment. It can be used independently, thus achieving both portability and good safety protection. Furthermore, it can be combined with a workstation, thereby achieving both good protection and convenient maintenance.

[0036] Figure 1 The diagram shows a structural schematic of the safety protection door opening and closing device of this utility model in one embodiment.

[0037] Figure 2 This invention presents a structural schematic diagram of the safety protection door opening and closing device according to one embodiment from another perspective.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the safety protection door opening and closing device may include: a support frame 1; a movable protective door 2, which is slidably disposed on the support frame 1; and a driving element 3, which is disposed on the support frame 1 to drive the movable protective door 2 to move along the support frame 1, thereby enabling the movable protective door 2 to switch between an opening position and a closing position.

[0039] Figure 1 and Figure 2 The display shows the state of the movable protective door 2 in the closed position. In this state, the operator is blocked behind the closed movable protective door, so the safety protection door opening and closing device can provide safety protection for the operator.

[0040] In some more specific embodiments, when the movable protective door 2 needs to be opened, the drive element 3 drives the movable protective door to slide vertically upwards along the height direction of the support frame, achieving a smooth opening of the movable protective door. When the movable protective door needs to be closed, the movable protective door 2 falls smoothly under the combined force of its own weight and the drive element 3. During this process, a certain counterforce can be applied to the movable protective door 2 by the drive element 3, thereby preventing the movable protective door 2 from falling rapidly and effectively avoiding the noise, impact damage, and wear that may be caused by excessive impact force of free fall.

[0041] It should be noted that in other embodiments, the movable protective door can also move horizontally along the support frame to switch between the opening and closing positions.

[0042] In some more specific embodiments, a linear guide rail extending along the height direction of the support frame can be provided on the support frame, and the movable protective door 2 is slidably mounted on the support frame via the linear guide rail. In this embodiment, by using a high-rigidity, low-friction linear guide rail, the sliding of the movable protective door can be guided, and friction and wear during the sliding process can be effectively reduced, thereby improving the service life of the sliding structure of the movable protective door.

[0043] In some more specific embodiments, the drive element 3 may include a rodless cylinder. The rodless cylinder has a compact structure and occupies little space. It can be installed on the side of the movable protective door, resulting in a more compact spatial structure and effectively avoiding the problem of the rod-type cylinder obstructing the view of the movable protective door. Furthermore, the speed of the rodless cylinder can be adjusted via a throttle valve, further ensuring the smooth opening and closing of the movable protective door.

[0044] In addition, such as Figure 1 and Figure 2 As shown, in some embodiments, the safety protection door opening and closing device may further include a protective door 4 fixedly mounted on the support frame 1. For example, Figure 1 and Figure 2 As shown, in the closed workstation, the fixed protective door 4 and the movable protective door form a complete protective barrier. During the switching to the open workstation, the movable protective door 2 moves toward the fixed protective door 4, thereby at least partially overlapping, or even completely overlapping, the fixed protective door in the open workstation.

[0045] In some more specific implementations, such as Figure 1 and Figure 2 As shown, the fixed protective door 4 has a trapezoidal cross-section. Furthermore, the movable protective door 2 can also have a trapezoidal cross-section. Unlike designs with straight cross-sections, the trapezoidal cross-section of the movable and / or fixed protective doors extends the distance between the operator and the equipment hazard source in the depth direction while ensuring effective operating space, thus increasing the safety protection distance.

[0046] In some implementations, such as Figure 2As shown, the safety protection door opening and closing device also includes an end buffer element 5, which can be installed on the support frame 1, the movable safety door 2, or both. The end buffer element 5 applies a buffering force to the movable safety door at the end of its stroke as it switches from the open position to the closed position, effectively absorbing the impact energy at the moving end of the movable safety door. This avoids the risk of excessive impact energy hitting the operator's hands, effectively improving the safety of the movable safety door during movement, and simultaneously enabling smooth operation with low impact and low noise.

[0047] like Figure 3 As shown, in some more specific embodiments, the end buffer element 5 may include an adjustable hydraulic buffer 51 disposed on the support frame 1, and a rubber buffer block 52 disposed on the upper end of the hydraulic buffer. In some more specific embodiments, the adjustable hydraulic buffer may be a hydraulic buffer.

[0048] Of course, in other implementations, rubber buffer blocks or similar buffer elements can also be installed on the movable protective door.

[0049] like Figure 2 As shown, in some embodiments, the safety door opening and closing device may further include a proximity switch 6, whose signal transmitting and receiving ends are respectively located on the movable safety door 2 and the support frame 1 at the end of the travel of the movable safety door from the open position to the closed position, to detect the fully closed state of the movable safety door 2. In this way, when the movable safety door is fully closed, the proximity switch 6 detects that the movable safety door has reached its position, confirming the safety of the work area. If the movable safety door is detected as not reaching its position, an alarm may be triggered or the mechanical equipment may be stopped to further ensure the safety of the operators.

[0050] like Figure 2 As shown, in some embodiments, the support frame 1 is provided with a flexible contact edge 7 at the position where it contacts the movable protective door in the closed position. This edge can effectively absorb the impact energy of the movable protective door when it is closed, and establish a buffer area for the movable protective door to fall into place. It can also avoid the risk of the operator's hand being pinched, thereby further improving safety.

[0051] In some more specific embodiments, the flexible contact edge 7 may include a flexible rubber strip with an air bladder cavity.

[0052] like Figure 2As shown, in some embodiments, the safety door opening and closing device may also include an anti-fall component. For example, the movable safety door may be provided with a locking pin 8 with a rotating handle 81, and the corresponding support frame is provided with a locking hole. During equipment maintenance, by rotating the handle 81, the spring locking pin at the front end of the handle will be inserted into the locking hole to fix the position of the movable safety door relative to the support frame, preventing the sliding door from accidentally falling during equipment maintenance.

[0053] In some more specific embodiments, the drive element 3 and the movable protective door 2 are not fixedly connected, but rather connected by contact. During the upward vertical movement of the movable protective door 2 along the support frame, the drive element moves the door by contacting and lifting it. For example, ... Figure 4 As shown, the movable safety door 2 can be pushed upward by the connecting plate 31. During the downward movement of the movable safety door to close, it moves downward under its own weight, while the drive element applies a reaction force, causing the movable safety door to move downward smoothly and in a controlled manner. Furthermore, when an operator needs to insert their arm or wrist into the lower end of the movable safety door, because the drive element 3 is in contact with the movable safety door, the drive element 3 can drive the connecting plate 31 to continue downward, while the movable safety door separates from the drive element. The movable safety door stops in mid-air due to the obstruction of the arm or wrist, effectively avoiding the risk of hand pinching.

[0054] In some more specific embodiments, a push plate 21 can be provided on the movable protective door 2 as shown in the figure, and a rubber buffer block 22 can be fixedly connected to the lower end of the push plate 21.

[0055] In some more specific embodiments, the support frame 1 may be made of aluminum alloy; and / or the movable protective door 2 may include a transparent polycarbonate sheet. This arrangement further reduces the weight of the safety protective door opening and closing device while ensuring stability, strength, and durability.

[0056] In another embodiment of this invention, a workstation is also provided.

[0057] Figure 5 The diagram shows the structure of the workstation according to this invention in one embodiment, with the safety protection door opening and closing device closed and the movable protective door in a closed state.

[0058] Figure 6 The diagram shows the structure of the workstation of the present invention in one embodiment, with the safety protection door device closed and the movable protective door open.

[0059] like Figure 5 and Figure 6As shown, in some embodiments, the workstation 100 includes a workstation housing 102 and a safety protection door device 101 connected to the workstation housing. For example... Figure 5 As shown, when the safety protection door opening and closing device 101 is closed and the movable protective door is also in the closed position, a relatively enclosed space is formed inside the workstation, which can effectively protect the operators outside the workstation. When the operator needs to operate the equipment inside the workstation, they can do so as follows: Figure 6 As shown, the safety protection door opening and closing device 101 remains closed, but the movable protective door is in the open position. At this time, because the opening operation window is small, it can still provide effective protection for the operator.

[0060] Figure 7 The diagram shows the opening of the safety protection door opening and closing device of the workstation described in this utility model in one embodiment.

[0061] like Figure 2 and Figure 7 As shown, in some more specific embodiments, the safety protection door opening and closing device and the workstation housing 102 can be hinged together via a hinge structure 103, thereby enabling convenient opening of the safety protection door opening and closing device 101. In this way, when the equipment in the workstation needs maintenance, the operator can rotate the safety protection door opening and closing device 101 by rotating the hinge structure 103, opening the front space of the workstation for easy access and operation.

[0062] Therefore, the safety protection door opening and closing device described in this utility model is easy to use, and its smooth sliding opening and closing method achieves a low noise effect, providing a safer and more comfortable experience for the working environment. In addition, it has high safety and can improve the safety and ease of operation of the manual operation station.

[0063] In addition, in some implementations, the use of end buffer elements ensures a smooth stop during the sliding process of the movable protective door, reducing impact energy.

[0064] In some implementations, proximity switches are used to ensure that the movable protective door is completely closed, preventing the accidental exposure of moving parts or hazardous conditions and further improving safety.

[0065] In some implementations, the support frame is made of aluminum alloy to ensure the structure's durability and long-term stability.

[0066] The workstation described in this invention simplifies maintenance operations and reduces operator risk through the rotating opening and closing of a safety-protected door device. The rotating opening and closing provides a spacious and convenient maintenance passage, further reducing the risk of injury to operators during maintenance.
