Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to an opening and closing device and a laser processing equipment. Background Technology

[0002] Laser processing equipment typically requires a dedicated processing space for safe workpiece processing. For example, in the field of laser processing equipment, lasers are high-brightness, high-power, and high-energy beams of light. Intense laser irradiation can cause burns to the skin; direct exposure to the eyes or reflection from a bright (mirror-like) surface can also cause injury. Therefore, it is crucial to avoid placing any part of the body in the path of the laser beam to prevent accidental injury. Due to the inherent dangers of lasers, appropriate protective measures must be incorporated into the design of laser products.

[0003] Currently, when processing products using laser processing equipment, it is necessary to use opening and closing devices to seal the product within a closed space. Existing laser processing equipment typically requires manual operation of these opening and closing devices, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure the safe closure of the devices, posing safety hazards. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the main objective of this application is to provide an opening and closing device and a laser processing equipment.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] According to a first aspect of the embodiments of this application, an opening and closing device is provided, comprising:

[0007] An opening / closing component, wherein the opening / closing component is provided with a first engaging portion;

[0008] A driving mechanism is used to drive the opening and closing member to move along a first direction;

[0009] A locking mechanism includes a main body and a second latching part. The locking mechanism is configured to drive the second latching part to extend out of the main body to give the second latching part a first position state, and the locking mechanism is configured to drive the second latching part to retract into the main body to give the second latching part a second position state.

[0010] When the second engaging part is in the first position, the second engaging part engages with the first engaging part to create a lock between the locking mechanism and the opening / closing member; when the second engaging part is in the second position, the second engaging part avoids the first engaging part to prevent interference between the locking mechanism and the opening / closing member.

[0011] Optionally, the first engaging portion includes a plurality of locking teeth, and a locking space is formed between two adjacent locking teeth. When the second engaging portion is in the first position state, the second engaging portion engages within the locking space.

[0012] Optionally, the locking tooth has an upper sidewall and a lower sidewall disposed opposite to each other. Along the first direction, the upper sidewall extends downward at an angle toward the locking mechanism. The second engaging portion has a first sidewall and a second sidewall disposed opposite to each other. Along the first direction, the first sidewall extends upward at an angle toward the distance from the main body portion.

[0013] When the second locking part is in the first position, the first sidewall abuts against the upper sidewall, and the second sidewall abuts against the lower sidewall of the adjacent locking tooth.

[0014] Optionally, the locking tooth is provided with a friction pattern on the side near the locking space, and when the second locking part is in the first position, the second locking part and the friction pattern are in contact.

[0015] Optionally, a first magnetic attraction part is provided on the side of the locking tooth near the locking space, and a second magnetic attraction part is provided on the second locking part. When the second locking part is in the first position state, the second magnetic attraction part and the first magnetic attraction part cooperate to realize the magnetic connection between the second locking part and the locking tooth.

[0016] Optionally, the opening and closing device further includes a drive rod, one end of which is connected to the drive mechanism and the other end of which is connected to the opening and closing member;

[0017] The drive rod is driven by the drive mechanism to drive the opening and closing member to rise or fall.

[0018] Optionally, the drive mechanism includes a drive piston and an exhaust valve, the exhaust valve having an open state or a closed state, the drive piston being movable when the exhaust valve is in the open state, and the drive piston being positioned when the exhaust valve is in the closed state, the drive piston being connected to one end of the drive rod;

[0019] When the second locking part is in the first position, the exhaust valve is in the closed state, so that the drive piston positions the drive rod.

[0020] Optionally, the opening and closing device further includes a detection mechanism for detecting the opening and closing element, and the detection mechanism is signal-connected to the drive mechanism;

[0021] When the detection mechanism fails to detect the opening / closing component, it controls the drive mechanism to stop working.

[0022] Optionally, the opening and closing device further includes a sensing mechanism, which is signal-connected to the locking mechanism, and the sensing mechanism has a triggered state and a sleep state;

[0023] When the sensing mechanism is in the triggered state, the second latching part is in the first position state; when the sensing mechanism is in the dormant state, the second latching part is in the second position state.

[0024] According to a second aspect of the present application, a laser processing apparatus is provided, including a laser processing platform, a housing, and an opening and closing device as described in any of the above embodiments, wherein the opening and closing device is installed between the housings, and the housing surrounds the laser processing platform.

[0025] The embodiments of this application have at least the following beneficial effects:

[0026] In the technical solution of this application, an automatic opening and closing mechanism is used to drive the opening and closing components to move along a first direction (such as the vertical direction), thereby achieving automatic opening or closing of the opening and closing device. During processing, the opening and closing components automatically descend and close under the driving action of the driving mechanism, thus protecting the operator from harm; after processing is completed, the opening and closing components automatically rise and open under the driving action of the driving mechanism, thus facilitating the rapid loading and unloading of processed parts. Compared with the traditional manual operation of the opening and closing components, the automatic driving method provided by this application significantly simplifies the operation process, saves time and labor, reduces the labor intensity and time cost of operators, and improves the overall operating efficiency of laser processing equipment.

[0027] By coordinating the drive mechanism and the locking mechanism, the power failure protection effect of the opening and closing device can be effectively improved, providing dual protection to prevent damage to the equipment and personnel safety issues caused by the opening and closing parts not responding in time during a sudden power failure. For example, during the normal lifting and lowering process of the opening and closing parts, if the opening and closing device experiences a sudden power failure, the drive mechanism will immediately stop working and position the opening and closing parts in their current position, ensuring that the opening and closing parts will not suddenly and rapidly fall, causing damage to the equipment or injuring on-site operators. At the same time, after the power failure, the locking mechanism will drive the second locking part to extend from the main body, so that the second locking part is in the first position, ensuring that the second locking part can promptly engage with the first locking part, providing contact resistance and mechanical locking for the opening and closing parts, preventing the opening and closing parts from automatically sliding downwards under the action of gravity, and further ensuring the positioning stability and reliability of the opening and closing parts.

[0028] Laser processing equipment using the above-mentioned opening and closing device can simplify the operation process of the opening and closing components, improve the processing efficiency of the laser processing equipment, and ensure the processing safety of the laser processing equipment.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0052] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0054] Laser processing equipment typically requires a dedicated processing space for safe workpiece processing. For example, in the field of laser processing equipment, lasers are high-brightness, high-power, and high-energy beams of light. Intense laser irradiation can cause burns to the skin; direct exposure to the eyes or reflection from a bright (mirror-like) surface can also cause injury. Therefore, it is crucial to avoid placing any part of the body in the path of the laser beam to prevent accidental injury. Due to the inherent dangers of lasers, appropriate protective measures must be incorporated into the design of laser products.

[0055] Currently, when processing products using laser processing equipment, it is necessary to use opening and closing devices to seal the product within a closed space. Existing laser processing equipment typically requires manual operation of these opening and closing devices, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure the safe closure of the devices, posing safety hazards.

[0056] Based on this, in order to solve the technical problems of inconvenient operation and safety hazards of the opening and closing parts 100 in current laser processing equipment, referring to Figures 1 to 7 This application provides an opening and closing device 10 in one embodiment. The opening and closing device 10 includes an opening and closing member 100, a driving mechanism 200, and a locking mechanism 300. The opening and closing member 100 is provided with a first engaging portion 110. For example, the first engaging portion 110 can be welded to the side of the opening and closing member 100, or the first engaging portion 110 can be bolted to the side of the opening and closing member 100, or the first engaging portion 110 and the opening and closing member 100 can be an integrally formed structure.

[0057] The drive mechanism 200 is used to drive the opening / closing member 100 to move along a first direction X. For example, the drive mechanism 200 can be a drive motor or a drive cylinder. The first direction X can be a vertical direction, that is, when welding the workpiece, the drive mechanism 200 can drive the opening / closing member 100 to descend vertically, ultimately putting the opening / closing device 10 in a closed state to prevent laser damage to the human body. After the workpiece is welded, the drive mechanism 200 can drive the opening / closing member 100 to rise vertically, ultimately putting the opening / closing device 10 in an open state to facilitate loading and unloading of the workpiece.

[0058] The locking mechanism 300 includes a main body 310 and a second engaging portion 320. The locking mechanism 300 is configured to drive the second engaging portion 320 out of the main body 310 to a first position state, and to drive the second engaging portion 320 back into the main body 310 to a second position state. For example, an electromagnet and an elastic element may be disposed inside the main body 310. The electromagnet generates magnetic force when energized, and the elastic element is disposed between the electromagnet and the second engaging portion 320. When the electromagnet is energized, it generates magnetic force, which magnetically attracts the second engaging portion 320 back into the main body 310, causing the second engaging portion 320 to switch from the first position state to the second position state. During the process of the second engaging portion 320 retracting into the main body 310, the second engaging portion 320 gradually compresses the elastic element, eventually placing the elastic element in a compressed state. When the electromagnet is de-energized, its magnetic force disappears, and it no longer magnetically attracts the second latching part 320. Furthermore, the elastic element tends to gradually recover its elastic deformation. Under the elastic force of the elastic element, the second latching part 320 gradually extends out of the main body 310, causing it to switch from the second position state to the first position state. Alternatively, the main body 310 can contain an electric cylinder and an elastic element. The electric cylinder generates driving force when energized, and the elastic element is positioned between the electric cylinder and the second latching part 320. The operation process of the combined driving method using an electric cylinder and an elastic element can be referenced from the operation process of the combined driving method using an electromagnet and an elastic element described above, and will not be repeated here. For example, when the electric cylinder is energized, it can retract the second latching part 320 into the main body 310; when the electric cylinder is de-energized, the elastic element can drive the second latching part 320 to extend out of the main body 310.

[0059] When the second engaging part 320 is in the first position, the second engaging part 320 engages with the first engaging part 110 to create a lock between the locking mechanism 300 and the opening / closing member 100; when the second engaging part 320 is in the second position, the second engaging part 320 avoids the first engaging part 110 to prevent interference between the locking mechanism 300 and the opening / closing member 100.

[0060] Specifically, by setting a drive mechanism 200 (such as a drive motor or drive cylinder) to automatically drive the opening and closing member 100 to move along the first direction X (such as the vertical direction), the opening and closing device 10 is automatically opened or closed. During (laser) welding, under the drive of the drive mechanism 200, the opening and closing member 100 will automatically descend and close, thereby protecting the operator from laser damage; after the (laser) welding is completed, under the drive of the drive mechanism 200, the opening and closing member 100 will automatically rise and open, thereby facilitating the rapid loading and unloading of the processed parts. Compared with the traditional manual operation of the opening and closing member 100, the automatic drive method provided by the drive mechanism 200 in this application greatly simplifies the operation process, saves time and effort, reduces the labor intensity and time cost of operators, and improves the overall operating efficiency of the laser processing equipment.

[0061] The cooperation between the drive mechanism 200 and the locking mechanism 300 effectively improves the power failure protection of the opening and closing device 10, providing dual protection to prevent damage to the equipment and personnel safety issues caused by the opening and closing component 100 not being able to respond in time during a sudden power failure. For example, during the normal lifting and lowering process of the opening and closing component 100, if the opening and closing device 10 experiences a sudden power failure, the drive mechanism 200 will immediately stop working and position the opening and closing component 100 in its current position, ensuring that the opening and closing component 100 will not suddenly and rapidly fall, causing damage to the equipment or injuring on-site operators. At the same time, after the power failure, the locking mechanism 300 will drive the second latching part 320 to extend out of the main body 310, so that the second latching part 320 is in the first position state, ensuring that the second latching part 320 can promptly latch onto the first latching part 110, providing contact resistance and mechanical locking for the opening and closing component 100, preventing the opening and closing component 100 from automatically sliding down under the action of gravity, and further ensuring the positioning stability and reliability of the opening and closing component 100.

[0062] Understandably, referring to Figures 4 to 7 The first engaging portion 110 includes a plurality of locking teeth 111, and a locking space 112 is formed between two adjacent locking teeth 111. When the second engaging portion 320 is in the first position, the second engaging portion 320 engages within the locking space 112. For example, a triangular locking space 112 can be formed between two adjacent locking teeth 111, so the second engaging portion 320 can be designed as a triangular structure, so that a stable engagement relationship can be formed between the second engaging portion 320 and the first engaging portion 110.

[0063] Specifically, the first latching part 110 forms multiple locking spaces 112, providing multiple locking points for the second latching part 320. When the opening / closing member 100 fails to precisely engage the second latching part 320 and the first latching part 110 due to errors in the driving mechanism 200 or external interference, the second latching part 320 will slide into a corresponding locking space 112 as the opening / closing member 100 slowly moves or falls. As long as the second latching part 320 falls into any locking space 112, effective locking between the second latching part 320 and the first latching part 110 can be achieved. This structure improves the positional tolerance of the second latching part 320, ensuring that the protection does not fail. Furthermore, the multiple locking points form a mechanical safety redundancy; even if one locking tooth 111 is damaged, the locking spaces 112 formed between other intact locking teeth 111 can still provide locking functionality for the second latching part 320, thereby improving overall failure safety.

[0064] Furthermore, when the second engaging portion 320 successfully engages within a locking space 112, it is usually accompanied by a perceptible mechanical action (such as a "click") or a change in position. This clear physical feedback helps the operator intuitively and reliably confirm that the opening / closing element 100 is in a valid locking state.

[0065] It is understood that the first latching portion 110 may also include a plurality of locking holes, and correspondingly, the second latching portion 320 may include a latching pin. When the second latching portion 320 is in the first position, the latching pin can be inserted into the locking hole to create a latch between the second latching portion 320 and the first latching portion 110. When the second latching portion 320 is in the second position, the latching pin can be moved out of the locking hole and avoid the locking hole to prevent interference between the second latching portion 320 and the first latching portion 110.

[0066] Understandably, referring to Figures 4 to 7 The locking tooth 111 has an upper sidewall 1111 and a lower sidewall 1112 disposed opposite to each other. Along a first direction X (e.g., the first direction X can be vertical), the upper sidewall 1111 extends downwards towards the locking mechanism 300. Correspondingly, the second engaging portion 320 has a first sidewall 321 and a second sidewall 322 disposed opposite to each other. Along the first direction X (e.g., the first direction X can be vertical), the first sidewall 321 extends upwards towards the direction away from the main body 310. When the second engaging portion 320 is in the first position, the first sidewall 321 abuts against the upper sidewall 1111, and the second sidewall 322 abuts against the lower sidewall 1112 of the adjacent locking tooth 111.

[0067] Specifically, by designing the upper sidewall 1111 of the locking tooth 111 to extend downwards towards the locking mechanism 300, and designing the first sidewall 321 of the second engaging portion 320 to extend upwards away from the main body 310, when the second engaging portion 320 engages in the locking space 112, the inclined sidewalls of the locking tooth 111 and the second engaging portion 320 form a mutually abutting inclined surface fit. This structure helps to increase the contact area between the second engaging portion 320 and the locking tooth 111, resulting in a tight fit between them and preventing the opening / closing member 100 from sliding down under its own weight. This, in turn, improves the positioning reliability and stability of the opening / closing member 100 at a certain position.

[0068] It is understood that the locking tooth 111 has a friction pattern (not shown in the figure) on the side near the locking space 112. When the second locking part 320 is in the first position, the second locking part 320 is in contact with the friction pattern.

[0069] Specifically, by providing friction patterns on the surface of the locking teeth 111, when the second engaging part 320 engages into the locking space 112 and contacts the surface of the locking teeth 111 near the locking space 112, the contact friction between the second engaging part 320 and the locking teeth 111 can be increased, preventing relative slippage between the second engaging part 320 and the locking teeth 111, ensuring the relative stability between the second engaging part 320 and the locking teeth 111, thereby improving the locking effect of the second engaging part 320 on the opening and closing member 100, and ensuring the reliability and stability of the opening and closing member 100 in the positioning position.

[0070] It is understood that a first magnetic attraction part (not shown in the figure) is provided on the side of the locking tooth 111 near the locking space 112, and a second magnetic attraction part (not shown in the figure) is provided on the second latching part 320. When the second latching part 320 is in the first position, the second magnetic attraction part and the first magnetic attraction part cooperate to realize the magnetic connection between the second latching part 320 and the locking tooth 111.

[0071] Specifically, assuming the second latching part 320 uses an electromagnetic drive, that is, the main body 310 is equipped with an electromagnet and an elastic element. When the electromagnet is energized, it can generate magnetism. The elastic element is located between the electromagnet and the second latching part 320. When the opening / closing member 100 moves normally, that is, when the second latching part 320 needs to be switched from the first position state to the second position state, sufficient current needs to be supplied to the electromagnet (it should be noted that the specific current value supplied to the electromagnet can be set according to the actual situation) so that the magnetic force generated by the electromagnet after being energized is still greater than the magnetic attraction between the first magnetic attraction part and the second magnetic attraction part after overcoming the elastic force of the elastic element. In this way, the second latching part 320 can be smoothly driven to retract into the main body 310, so that the second latching part 320 and the locking tooth 111 are separated, ensuring that the second latching part 320 does not affect the movement of the opening / closing member 100. When the opening / closing component 100 encounters a power outage or other malfunction, requiring the second locking part 320 to switch from the second position to the first position, the electromagnet needs to be de-energized. At this time, under the elastic force of the elastic element and the magnetic attraction of the first and second magnetic parts, the second locking part 320 can quickly and accurately engage within the locking space 112, forming a stable engagement with the locking teeth 111. Through the cooperation between the second and first magnetic parts, the second locking part 320 is effectively prevented from disengaging from the locking space 112, thereby improving the locking and positioning effect of the second locking part 320 on the opening / closing component 100, ensuring the positioning stability and reliability of the opening / closing component 100, and preventing the opening / closing component 100 from falling freely under its own weight.

[0072] Understandably, referring to Figures 1 to 7 The opening and closing device 10 also includes a drive rod 400, one end of which is connected to the drive mechanism 200, and the other end of which is connected to the opening and closing member 100. The drive rod 400 is driven by the drive mechanism 200 to raise or lower the opening and closing member 100. For example, one end of the drive rod 400 can be connected to the output shaft of the drive mechanism 200. Taking the first direction X as the vertical direction as an example, the output shaft can drive the drive rod 400 to extend and retract vertically, thereby enabling the drive rod 400 to drive the opening and closing member 100 to move up and down.

[0073] Specifically, under normal operating conditions, when the opening / closing element 100 needs to be opened, the drive mechanism 200 is activated, causing its output shaft to rotate forward. This output shaft extends the drive rod 400, which in turn drives the opening / closing element 100 to rise until it reaches the target position. When the opening / closing element 100 needs to be closed, the drive mechanism 200 is activated, causing its output shaft to rotate in reverse. This output shaft retracts the drive rod 400, which then lowers the opening / closing element 100 until it is fully closed. In the event of a power outage or other malfunction, the drive mechanism 200 stops operating, stopping its output shaft from rotating. The drive rod 400 is then positioned at a specific length, supporting the opening / closing element 100 in a fixed position. This prevents the opening / closing element 100 from suddenly falling during a malfunction, which could damage the equipment or cause other safety accidents, ensuring processing safety in the event of an emergency.

[0074] By directly driving the opening and closing element 100 to move via the drive rod 400, the control accuracy of the drive rod 400 on the opening and closing element 100 can be improved, the response time of the opening and closing element 100 to the drive rod 400 can be shortened, and the drive rod 400 has high structural strength, which can provide stable and reliable support for the opening and closing element 100 and prevent the opening and closing element 100 from shaking during movement.

[0075] It is understood that the drive mechanism 200 includes a drive piston and an exhaust valve. The exhaust valve has an open state or a closed state. When the exhaust valve is in the open state, the drive piston can move. When the exhaust valve is in the closed state, the drive piston can be positioned. The drive piston is connected to one end of the drive rod 400. Specifically, when the second engaging part 320 is in the first position state, the exhaust valve is in the closed state, so that the drive piston positions the drive rod 400.

[0076] Specifically, when the drive mechanism 200 is operating normally, the exhaust valve is in the open state. The exhaust valve changes the connectivity of the internal air passages of the drive mechanism 200, thereby altering the flow direction of the compressed gas within the drive mechanism 200, ultimately achieving pneumatic drive of the drive piston by the compressed gas. For example, when the compressed gas pressure inside the drive mechanism 200 is high, the drive piston moves outward, causing the drive rod 400 to extend, which in turn drives the opening / closing element 100 to rise. When the compressed gas pressure inside the drive mechanism 200 is low, the drive piston moves inward, causing the drive rod 400 to retract, which in turn drives the opening / closing element 100 to descend. When the drive mechanism 200 stops operating, the exhaust valve is in the closed state. At this time, the internal air pressure of the drive mechanism 200 remains constant, and the drive piston ceases to move, causing the drive rod 400 to be positioned at a certain length. The drive rod 400 supports the opening / closing element 100, keeping it fixed.

[0077] The drive mechanism 200 and the locking mechanism 300 are linked for control. That is, when the opening and closing device 10 is working normally, both the drive mechanism 200 and the locking mechanism 300 are energized. When the drive mechanism 200 drives the opening and closing member 100 to move along the first direction X (up and down) through the drive rod 400, the second latching part 320 can retract into the main body part 310 (that is, the second latching part 320 switches from the first position state to the second position state), ensuring that the second latching part 320 will not interfere with the moving opening and closing member 100 and improving the movement flexibility of the opening and closing member 100. When the opening and closing device 10 malfunctions, both the drive mechanism 200 and the locking mechanism 300 lose power. This allows the second latching part 320 to extend out of the main body 310 when the drive mechanism 200 drives the opening and closing member 100 to position via the drive rod 400 (i.e., the second latching part 320 switches from the second position state to the first position state). This ensures a double lock on the opening and closing member 100 (the first lock is the support and fixation of the opening and closing member 100 by the drive rod 400, and the second lock is the latching and blocking of the opening and closing member 100 by the second latching part 320), thereby improving the positioning safety of the opening and closing member 100 in the event of a malfunction.

[0078] It is understood that the opening and closing device 10 also includes a detection mechanism (e.g., a position sensor) (not shown in the figure), which is used to detect the opening and closing element 100. The detection mechanism and the drive mechanism 200 are signal connected. When the detection mechanism does not detect the opening and closing element 100, the detection mechanism controls the drive mechanism 200 to stop working.

[0079] Specifically, the detection mechanism may include a transmitter and a receiver, which may be respectively located on opposite sides of the opening / closing member 100. When the opening / closing member 100 moves according to a predetermined stroke, the receiver cannot receive the signal emitted by the transmitter due to the obstruction of the opening / closing member 100. When the movement trajectory of the opening / closing member 100 deviates, the receiver can receive the signal emitted by the transmitter due to the absence of the obstruction of the opening / closing member 100. At this time, the detection mechanism transmits the signal to the control center, which then controls the drive mechanism 200 to stop working, ensuring that the opening / closing member 100 can be positioned in a timely manner, preventing the opening / closing member 100 from deviating too much, and realizing over-travel protection for the opening / closing member 100.

[0080] Understandably, referring to Figure 1 The opening and closing device 10 also includes a sensing mechanism 500 (for example, the sensing mechanism 500 can be a safety light curtain). The sensing mechanism 500 is signal-connected to the locking mechanism 300. The sensing mechanism 500 has a triggered state and a dormant state. When the sensing mechanism 500 is in the triggered state, the second latching part 320 is in a first position state; when the sensing mechanism 500 is in the dormant state, the second latching part 320 is in a second position state.

[0081] Specifically, the sensing mechanism 500 may have an infrared sensing function to detect whether an operator is approaching the opening and closing device 10. When an operator approaches the opening and closing device 10 and crosses the safe distance range, the sensing mechanism 500 will be triggered, putting the sensing mechanism 500 into a triggered state. At this time, the sensing mechanism 500 will transmit the corresponding signal to the control center, causing the control center to de-energize the locking mechanism 300, ensuring that the second latching part 320 can extend out of the main body 310 and latch with the first latching part 110, preventing the opening and closing member 100 from continuing to move and preventing the moving opening and closing member 100 from accidentally injuring the operator. When the operator moves away from the closing device 10 and reaches a safe distance, the sensing mechanism 500 will re-enter the sleep state. At this time, the sensing mechanism 500 will transmit the corresponding signal to the control center, which will then energize the locking mechanism 300 to ensure that the second latching part 320 can retract into the main body 310, thereby avoiding interference between the second latching part 320 and the opening / closing member 100 and ensuring that the opening / closing member 100 can move normally.

[0082] Correspondingly, another embodiment of this application also provides a laser processing device, which includes a laser processing platform, a machine cover, and an opening and closing device 10 as described in any of the above embodiments. The opening and closing device 10 is installed between the machine covers, and the machine covers surround the laser processing platform.

[0083] For example, when processing a workpiece using laser processing equipment, the opening and closing element 100 in the opening and closing device 10 can be lowered, placing the laser processing equipment in a closed processing environment to prevent the processing laser or the iron filings generated during processing from adversely affecting the on-site operators. When loading and unloading materials into the laser processing equipment, the opening and closing element 100 in the opening and closing device 10 can be raised, placing the laser processing equipment in an open processing environment, thereby facilitating the transfer of workpieces (one possible implementation is to use a robotic arm to transfer the workpiece).

[0084] The laser processing equipment using the above-mentioned opening and closing device 10 can simplify the operation process of the opening and closing component 100, improve the processing efficiency of the laser processing equipment, and ensure the processing safety of the laser processing equipment.

[0085] Thanks to the improvements to the opening and closing device 10, the laser processing equipment of this embodiment has the same technical effects as the opening and closing device 10, which will not be described in detail here.

[0086] It should be noted that other undisclosed aspects of the opening and closing device 10 and laser processing equipment provided in this application can be found in the prior art, and will not be repeated here.

[0087] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
