[0033] 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.

[0034] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0035] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] It should be understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] Please see Figures 1 to 4 This utility model provides a sheet metal limiting device 100, including a support member 10, two limiting drawers 20, a sheet metal limiting assembly 30, and a drawer movement drive 40. The two limiting drawers 20 are sequentially disposed on the support member 10, and each limiting drawer 20 can move relative to the support member 10 along a first direction. Each limiting drawer 20 includes a processing bearing area 21, and a waste material through hole 211 is provided on the processing bearing area 21. The sheet metal limiting assembly 30 is disposed on the processing bearing area 21 and is used to limit the sheet metal. The drawer movement drive 40 is disposed on the support member 10 and is drively connected to the limiting drawers 20 to drive the limiting drawers 20 to move relative to the support member 10 along the first direction.

[0039] In this embodiment of the utility model, when the limiting drawer 20 carries the plate for processing, the slag generated during plate processing leaks out through the waste through hole 211, avoiding slag accumulation. This prevents the slag from affecting the limiting position or causing sparks to fly when the laser touches the slag. In addition, the two limiting drawers 20 can be processed alternately, so that when the plate on one limiting drawer 20 is being processed, the other limiting drawer 20 can be loaded and unloaded, improving processing efficiency.

[0040] Specifically, the support member 10 is used to support the limiting drawer 20, the drawer movement drive member 40, etc. The support member 10 has various structures; it may include a drawer opening that opens in a first direction to allow the two limiting drawers 20 to pass through. Understandably, one end of the limiting drawer 20 may have an abutment protrusion for abutting against the support member 10 around the drawer opening. This prevents the limiting drawer 20 from fully entering the drawer opening, facilitating the operator to pull out or put back the limiting drawer 20.

[0041] The limiting drawer 20 is used to limit and support the sheet metal. The sheet metal is placed in the processing support area 21, which supports the sheet metal for processing. Understandably, the processing support area 21 can have a variety of waste material through holes 211, such as 1, 2, 3, 4, 5, or 6. The number of waste material through holes 211 is adjusted according to their shape and the required processing position of the sheet metal. Understandably, the waste material through holes 211 are located below the position of the sheet metal to be processed, so that the slag generated after processing can be directly discharged through the waste material through holes 211. Therefore, the position of the waste material through holes 211 in the processing support area 21 is adjusted according to the position of the sheet metal to be processed.

[0042] Understandably, each of the two limit drawers 20 is provided with a processing bearing area 21, and both processing bearing areas 21 of the two limit drawers 20 are provided with waste material through holes 211.

[0043] It is worth noting that in one embodiment, the plate limiting device 100 may also include 3, 4, 5 or other limiting drawers 20. The plate limiting device 100 may include at least two limiting drawers 20. This application does not impose any specific restrictions.

[0044] It is worth noting that the limit drawer 20 may also be equipped with a pop-out button and a reset button. The support frame has a drawer opening. The pop-out button is used to control the limit drawer 20 to pop out from the drawer opening, and the reset button is used to control the limit drawer 20 to reset from the drawer opening. This allows for convenient control of the limit drawer 20's entry and exit for loading / unloading materials or supporting sheet metal processing. Understandably, the pop-out button and reset button can communicate with the drawer movement drive component 40. The limit drawer 20 can also engage with the support frame around the drawer opening. The pop-out button can be connected to the engagement point between the limit drawer 20 and the support frame. These details will not be listed individually in this application.

[0045] The sheet metal limiting component 30 is used to limit the sheet metal. Understandably, the sheet metal limiting component 30 has many structures. In one embodiment, the sheet metal limiting component 30 is disposed on the processing support area 21, and the sheet metal limiting component 30 has a limiting groove for accommodating and limiting the sheet metal. In another embodiment, the sheet metal limiting component 30 includes a clamping member that can move towards or away from the limiting drawer 20. After the sheet metal is placed in the processing support area 21, the clamping member moves towards the limiting drawer 20, pressing the sheet metal against the processing support area 21.

[0046] Understandably, each processing load-bearing area 21 is equipped with a plate limiting component 30 to ensure that the plate is limited during the processing of the plate in each processing load-bearing area 21, thus preventing the plate from shaking during processing.

[0047] The drawer movement drive 40 is used to drive the limit drawer 20 to move along a first direction. It is understood that the drawer movement drive 40 has many structures, including motors, cylinders, and other drive components; this application does not impose any specific limitations.

[0048] It is worth noting that, in one embodiment, the drawer movement drive 40 includes an adjustable, buffered, magnetized cylinder. This allows for easier adjustment of the travel of the limit drawer 20, reducing the requirements for manufacturing and installation precision.

[0049] It is worth noting that, in one embodiment, the drawer moving drive 40 may further include two stroke detection elements, which are located at opposite ends of the stroke of the output end of the drawer moving drive 40. This allows for the detection of whether the output end of the drawer moving drive 40 has moved into position, thereby determining whether the limit drawer 20 has moved into position, and avoiding problems such as poor processing quality or inaccurate loading / unloading caused by the limit drawer 20 not moving into position.

[0050] Please see Figure 1 and Figure 4In this embodiment of the present invention, the processing bearing area 21 further includes a first work station area 213 and a second work station area 215. The first work station area 213 and the second work station area 215 are used to support the plate respectively. Both the first work station area 213 and the second work station area 215 are provided with waste material through holes 211. The plate limiting component 30 is provided in the first work station area 213 and the second work station area 215.

[0051] In this way, the processing bearing area 21 can support at least two plates for processing, further improving processing efficiency.

[0052] Understandably, the processing area 21 carries at least two boards for processing, which increases the processing time of each processing area 21. This provides more time for loading and unloading in the other processing area 21, reducing the probability that the boards in one processing area 21 have been processed while the boards in the other processing area 21 have not been loaded or unloaded. In addition, it is understandable that compared to pulling out the limit drawer 20 each time and placing one board on the processing area 21, pulling out and placing two boards at the same time can achieve loading and unloading more efficiently.

[0053] Understandably, the first workstation area 213 and the second workstation area 215 can be arranged sequentially along the first direction, and the first workstation area 213 and the second workstation area 215 can be arranged sequentially along the second direction, which is perpendicular to the first direction. The arrangement of the first workstation area 213 and the second workstation area 215 can also be adjusted according to factors such as the shape and size of the board and the shape and size of the limit drawer 20. This application does not impose specific restrictions.

[0054] For further details, please refer to Figure 1 and Figure 3 The waste through-hole 211 in the first work station area 213 and the waste through-hole 211 in the second work station area 215 are spaced apart, and the interval forms a wiring area 217.

[0055] In this way, a wiring area 217 is naturally formed at the interval, which can cover the wiring and allow the wiring to pass through, improving the space utilization rate and avoiding the risk of the wiring being damaged by sparks.

[0056] Understandably, since the waste through-hole 211 of the first workstation area 213 and the waste through-hole 211 of the second workstation area 215 are spaced apart, the space can provide cover for the circuit. The position of the limiting drawer 20 with the first workstation area 213 and the second workstation area 215 carries the workpiece for laser processing, while the position of the limiting drawer 20 without the waste through-hole 211 can block the laser and sparks. Thus, a wiring area 217 is formed on the side of the limiting drawer 20 away from the first workstation area 213. The circuit is arranged through the wiring area 217, and the physical body of the limiting drawer 20 provides cover for the circuit.

[0057] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment of the utility model, the plate limiting component 30 includes a first limiting member 31, two second limiting members 33, and a spacer limiting member 35. The first limiting member 31 is arranged along the second direction and is located on one side of the processing bearing area 21 along the first direction. The two second limiting members 33 are arranged along the first direction and are spaced apart along the second direction. The two second limiting members 33 are located on both sides of the processing bearing area 21. The spacer limiting member 35 is arranged along the first direction and is located between the first work station area 213 and the second work station area 215.

[0058] Thus, the first limiting member 31 can limit the plate along the first direction, and the spacer limiting member 35 can cooperate with the two limiting members. The spacer limiting member 35 and the two limiting members together limit the plate on the first work station area 213 and the second work station area 215 along the second direction, thereby realizing multi-directional limiting of the plate and ensuring that the plate is in the required processing position.

[0059] For further details, please refer to Figure 1 , Figure 2 and Figure 4 The second limiting member 33 includes a first part 331 and a second part 333. The first part 331 is connected to the first limiting member 31. The second part 333 is spaced apart from the first part 331 along a first direction. The second part 333 is provided with a waist-shaped hole 3331. The length direction of the waist-shaped hole 3331 is arranged along a second direction. The second part 333 is bolted to the limiting drawer 20 through the waist-shaped hole 3331.

[0060] Thus, the second part 333 is spaced apart from the first part 331, which reduces the length requirement of the second limiting member 33 while limiting the plate over a longer distance. This reduces the probability of the plate easily wobbling when only one end is limited in the second direction. In addition, since the second part 333 is provided with a waist-shaped hole 3331, the position of the second part 333 can be finely adjusted in the second direction as needed, thereby adapting to production and installation errors and better matching the plate limiting requirements.

[0061] Understandably, since the first part 331 and the second part 333 limit the board material, and the position between the first part 331 and the second part 333 has a limited effect on limiting the board material, the first part 331 and the second part 333 are set alternately, and the limiting structure between the first part 331 and the second part 333 is omitted. This reduces costs while ensuring the limiting effect on the board material.

[0062] It is worth noting that the spacer limiting member 35 may include a third part and a fourth part, which are spaced apart along the first direction. In this way, the length requirement of the spacer limiting member 35 is reduced while ensuring that the spacer limiting member 35 can effectively limit the plate.

[0063] For further details, please refer to Figure 2 The processing bearing area 21 also includes multiple adjustment holes 219, which are arranged along the first direction. The second part 333 can be bolted to different adjustment holes 219.

[0064] In this way, the connection between the second part 333 and different adjustment holes 219 can be adjusted as needed, thereby adjusting the distance between the second part 333 and the first part 331 to adapt to the limiting requirements of different sized plates.

[0065] It is worth noting that, in one embodiment, the processing bearing area 21 further includes multiple spaced holes arranged along the first direction, and the fourth part is bolted to different spaced holes. Thus, the connection between the fourth part and different adjustment holes 219 can be adjusted as needed, thereby adjusting the distance between the fourth part and the third part to accommodate the limiting requirements of plates of different sizes.

[0066] Understandably, in one embodiment, the fourth part is located between the two second parts 333, and the two second parts 333 and the fourth part are arranged along the second direction. In this way, the second parts 333 and the fourth part can face each other along the second direction, so that force can be applied to the same position of the plate along the second direction, avoiding the plate tilting caused by the plate's contact position with the second part 333 being different from the plate's contact position with the fourth part.

[0067] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment of the utility model, the plate limiting device 100 further includes a plate detection component 50 and an electromagnet 60. The plate limiting device 100 also includes a plate detection component 50 and an electromagnet 60. Both the plate detection component 50 and the electromagnet 60 are located in the processing bearing area 21. The processing bearing area 21 is provided with a receiving cavity 23. The plate detection component 50 includes a rotating shaft 51 and a toggle switch 53. The rotating shaft 51 is located on the cavity wall of the receiving cavity 23. The toggle switch 53 is rotatably connected to the limiting drawer 20 through the rotating shaft 51. At least a part of the toggle switch 53 extends beyond the receiving cavity 23. The toggle switch 53 can rotate under the action of the plate and be received in the receiving cavity 23. The electromagnet 60 is communicatively connected to the plate detection component 50.

[0068] Thus, the plate detection component 50 can detect whether the plate is placed on the processing bearing area 21. Based on the result of the plate detection component 50, the electromagnet 60 is energized to attract the plate, thereby realizing automatic adsorption and positioning of the plate.

[0069] Specifically, and understandably, when no sheet metal is placed on the processing support area 21, at least a portion of the toggle switch 53 extends beyond the receiving cavity 23. After the sheet metal is placed on the processing support area 21, the weight of the sheet metal acts on the toggle switch 53, causing the toggle switch 53 to rotate relative to the limit drawer 20 into the receiving cavity 23, thereby detecting whether the sheet metal is placed on the processing support area 21. When the sheet metal detection component 50 detects a sheet metal on the processing support area 21, the electromagnet 60 is energized, thereby attracting and limiting the sheet metal to prevent it from shaking during processing.

[0070] Understandably, there are many structures in which the plate material detection component 50 keeps at least a portion of the toggle switch 53 outside the receiving cavity 23. For example, the plate material detection component 50 may be equipped with a torsion spring that provides elasticity for at least a portion of the toggle switch 53 to extend beyond the receiving cavity 23. Alternatively, the center of gravity of the toggle switch 53 may be spaced apart from the rotation axis 51, and the toggle switch 53 may keep at least a portion of the toggle switch outside the receiving cavity 23 under the action of gravity. These are not listed one by one in this application.

[0071] It is understandable that there are many ways to communicate between the electromagnet 60 and the plate detection component 50. The electromagnet 60 and the plate detection component 50 can be connected through a mechanical structure, or they can be connected through wires, etc. As long as the electromagnet 60 can be energized in response to the detection result of the plate detection component 50, this application does not impose specific restrictions on the communication connection method.

[0072] Please see Figure 1 and Figure 4 In this embodiment of the utility model, the limiting drawer 20 is provided with a drawer handle 25 at one end along the first direction. The limiting drawer 20 also includes a covering area 27. Along the direction close to the drawer handle 25, the covering area 27 and the processing bearing area 21 are arranged in sequence. The covering area 27 can cover the drawer moving drive component 40.

[0073] In this way, the covering area 27 can cover the drawer movement drive 40, preventing the sparks generated during laser or laser processing from affecting the drawer movement drive 40 and ensuring the service life of the drawer movement drive 40.

[0074] Please see Figure 3 In this embodiment of the utility model, the plate limiting device 100 further includes a limiting guide rail 70, which is arranged along the first direction, and the limiting drawer 20 is slidably connected to the support member 10 through the limiting guide rail 70.

[0075] In this way, the limiting guide rail 70 can guide the relative movement between the limiting drawer 20 and the support member 10, reduce the force required to be borne by the drawer movement drive member 40, and also reduce the probability of the limiting drawer 20 shaking when moving relative to the support member 10.

[0076] Understandably, the limiting guide rail 70 can be mounted on the support member 10, or it can be mounted on the limiting drawer 20. Understandably, the plate limiting device 100 can also be equipped with a limiting slider that cooperates with the limiting guide rail 70. When the limiting guide rail 70 is mounted on the limiting drawer 20, the limiting slider is mounted on the support member 10, and the limiting slider and the limiting guide rail 70 cooperate to guide the limiting drawer 20; when the limiting guide rail 70 is mounted on the support member 10, the limiting slider is mounted on the limiting drawer 20, and the limiting slider and the limiting guide rail 70 cooperate to guide the limiting drawer 20.

[0077] This utility model embodiment also provides a processing device, which includes a laser and a plate limiting device 100. The specific structure of the plate limiting device 100 is as described in the above embodiments. Since this processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0078] In the processing equipment of this utility model embodiment, when the limiting drawer 20 carries the plate for processing, the slag generated during plate processing leaks out through the waste through hole 211, avoiding slag accumulation. This prevents the slag from affecting the limiting position or the laser from touching the slag and causing sparks to fly. In addition, the two limiting drawers 20 can be processed alternately, so that when the plate on one limiting drawer 20 is being processed, the other limiting drawer 20 can be loaded and unloaded, improving processing efficiency.

[0079] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
