Description

Technical Field

[0001] This utility model relates to the field of speaker grille processing technology, and in particular to a high-speed laser cutting device for speaker grilles. Background Technology

[0002] Laser cutting technology has become one of the mainstream processes for cutting holes in speaker grilles due to its advantages such as high precision, high speed, and non-contact processing.

[0003] Traditional laser cutting devices for speaker grilles typically consist of a machine base, a crossbeam, and a laser cutting machine mounted on the crossbeam. A servo motor drives gears and racks to precisely move the crossbeam and cutting machine within a two-dimensional plane, thus completing complex cutting paths. However, in actual production, especially under prolonged and high-intensity operation, this type of device reveals a significant drawback: insufficient dust protection.

[0004] Laser cutting of metal or plastic mesh generates a large amount of fine dust and particulate matter. While some existing equipment incorporates accordion covers on moving parts (such as the connection between the beam and the machine body) to block most of the dust, the inventors discovered that for two cutting machines placed side-by-side and requiring independent or synchronous movement, the area between them becomes a weak point in dust prevention. This area is typically directly exposed to the external environment, making it highly susceptible to dust settling and penetrating the precision track and rack and pinion drive system at the top of the beam.

[0005] Long-term dust accumulation can lead to a series of problems: First, it accelerates mechanical wear on tracks and gears, affecting transmission accuracy and smoothness, ultimately causing deviations in the cutting position and reducing product yield. Second, dust may adhere to the laser head's lenses, affecting beam quality and even damaging the expensive laser. Furthermore, frequent downtime for cleaning and maintenance not only reduces equipment production efficiency but also increases labor costs and consumable replacement expenses. While bellows covers can solve some problems, they cannot provide effective sealing protection for the "open" area between two dynamically changing cutting machines, creating significant dust-proof blind spots.

[0006] Therefore, there is an urgent need in this field for an improved laser high-speed cutting device for speaker grilles that can effectively solve the dust prevention problem in the area between the two cutting machines, reduce equipment failure rate, improve operational stability and service life, and facilitate maintenance. Utility Model Content

[0007] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0008] Therefore, one objective of this utility model is to provide a high-speed laser cutting device for speaker grilles, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0009] To achieve the above objectives, one embodiment of the present invention provides a high-speed laser cutting device for speaker grilles, comprising a machine base, a machine body, a track, a rack, a crossbeam, and a servo motor. The machine body is fixedly connected to the side of the machine base, and the track and rack are fixedly connected to the top of the machine body. The crossbeam is movably connected to the outer surface of the track, and the servo motor is fixedly connected to the top of the crossbeam. The gear at the output end of the servo motor is movably connected to the rack. The top and front of the crossbeam are fixedly connected to a rail, and the top of the crossbeam is fixedly connected to a rack. Two hole cutting machines are movably connected to the outer surface of the rail. A laser head is fixedly connected to the bottom of the hole cutting machine, and a servo motor is fixedly connected to the top of the hole cutting machine. The gear at the output end of the servo motor is movably connected to the corresponding rack. The side of the hole cutting machine is fixedly connected to both ends of the crossbeam, and the accordion cover is movably connected to the top and front of the crossbeam. A connector is fixedly connected to the other side of the hole cutting machine. The connector is bent and has positioning holes at both ends and at the bend. A pressure plate is detachably connected to the front of the connector. A connector is inserted into the corresponding position of the pressure plate and is threaded to the corresponding positioning hole. An elastic cover is clamped between the connector and the pressure plate. The elastic cover is retractable and is located between the two hole cutting machines.

[0010] Preferably, in any of the above embodiments, the track at the top of the machine body is located on the side of the corresponding rack, and the crossbeam can move bidirectionally on the track.

[0011] The above technical solution employs the following: the machine base serves as the fundamental support structure for the entire device, providing a stable mounting platform for other components. The machine body is fixed to the side of the machine base, and a track and rack are mounted on the top of the machine body. A crossbeam is movably connected to the track on the top of the machine body, and a servo motor is fixed to the top of the crossbeam. The output gear of this servo motor meshes with the rack. When the servo motor starts, its output gear rotates on the rack, thereby driving the crossbeam to move bidirectionally along the track.

[0012] Tracks are fixed to the top and front of the crossbeam, and a rack is also provided on the top of the crossbeam. Two hole cutters are movably connected to the tracks on the crossbeam, and each hole cutter is also equipped with a servo motor on its top. The output gears of these servo motors mesh with the rack on the crossbeam. By operating the servo motors on the top of the hole cutters, the hole cutters can be driven to move bidirectionally on the tracks of the crossbeam.

[0013] The bottom of the hole cutting machine is equipped with a laser head, with the end of the laser head facing downwards. When the hole cutting machine moves to the appropriate position, the laser head emits a laser beam to cut holes in the speaker grille placed below.

[0014] A bellows cover is fixed between the side of the hole cutting machine and both ends of the crossbeam. The bellows cover is movably connected to the top and front of the crossbeam and can extend and retract as the crossbeam and the hole cutting machine move, thus playing a certain role in dust prevention and protecting the internal structure.

[0015] A 90-degree bent connector is fixed to the other side of the hole cutter, with positioning holes at both ends and the bend. A pressure plate is detachably connected to the front of the connector, and hexagonal screws are inserted into corresponding positions on the pressure plate, threaded into the positioning holes. A retractable elastic cover made of fluororubber is sandwiched between the connector and the pressure plate, positioned between the two hole cutters. The elastic cover effectively prevents dust from entering the area between the two hole cutters, protecting components such as the track and rack on the crossbeam and reducing dust traps.

[0016] Preferably, in any of the above embodiments, the servo motor is installed vertically, the servo motor is connected to the crossbeam via a flange, and the servo motor is connected to the hole cutting machine via a flange.

[0017] Preferably, in any of the above embodiments, the hole cutting machine can move bidirectionally on the track, with the end of the laser head facing downwards.

[0018] The core design of the device is as follows: A detachable elastic cover made of fluororubber is installed between the two hole cutters, providing excellent elasticity and sealing. During the movement of the hole cutters, the elastic cover expands and contracts with their changing positions, always tightly covering the area between the two machines, effectively preventing dust from entering. Simultaneously, the bellows cover also serves to protect the area between the crossbeam and the hole cutters from dust. This dual dustproof design significantly reduces dust corrosion of critical transmission components such as the track and rack, lowers the probability of wear and failure caused by dust, extends the service life of the device, and reduces maintenance costs.

[0019] The flexible cover's bending shape and stretchable properties allow it to better adapt to the movement trajectory of the hole-cutting machine, covering areas that are difficult to reach with traditional dustproofing methods, reducing dust blind spots. This ensures that critical components inside the device are always in a relatively clean working environment, guaranteeing the stability of the device's operation and the accuracy of the hole cutting.

[0020] The elastic cover is detachably connected to the connector via a pressure plate and hexagonal screws. When the elastic cover is damaged or requires cleaning, workers can easily remove it for replacement or cleaning and then reinstall it. This detachable design greatly improves the ease of maintenance of the device and reduces maintenance time and costs.

[0021] Preferably, of any of the above solutions, the accordion cover is made of plastic and the joint is bent at a 90-degree angle.

[0022] Preferably, in any of the above solutions, the connector is a hexagonal socket screw, and the pressure plate is bent at a 90-degree angle.

[0023] Preferably, the elastic cover is made of fluororubber, as described in any of the above embodiments.

[0024] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This high-speed laser cutting device for speaker grilles features a detachable elastic cover between two cutting machines. Made of fluororubber, the cover offers excellent elasticity and sealing. As the cutting machines move, the cover expands and contracts with their position, always tightly covering the area between them, effectively preventing dust from entering. Simultaneously, the accordion cover also protects the area between the crossbeam and the cutting machines from dust. This dual dustproof design significantly reduces dust corrosion of critical transmission components such as the track and rack, lowering the probability of wear and failure caused by dust, extending the device's lifespan, and reducing maintenance costs.

[0025] The flexible cover's bending shape and stretchable properties allow it to better adapt to the movement trajectory of the hole-cutting machine, covering areas that are difficult to reach with traditional dustproofing methods, reducing dust blind spots. This ensures that critical components inside the device are always in a relatively clean working environment, guaranteeing the stability of the device's operation and the accuracy of the hole cutting.

The gear at the output end of the servo motor 6 is movably connected to the corresponding rack 4. A bellows cover 9 is fixedly connected between the side of the hole cutting machine 7 and both ends of the crossbeam 5. The bellows cover 9 is movably connected to the top and front of the crossbeam 5. The other side of the hole cutting machine 7 is fixedly connected to a connector 10. The connector 10 is bent.

[0034] Example 2: The machine base 1 serves as the basic support structure for the entire device, providing a stable mounting platform for other components. The machine body 2 is fixed to the side of the machine base 1, and a track 3 and a rack 4 are mounted on the top of the machine body 2. A crossbeam 5 is movably connected to the track 3 on the top of the machine body 2, and a servo motor 6 is fixed to the top of the crossbeam 5. The output gear of the servo motor 6 meshes with the rack 4. When the servo motor 6 is started, its output gear rotates on the rack 4, thereby driving the crossbeam 5 to move bidirectionally on the track 3.

[0035] Tracks 3 are fixed to the top and front of the crossbeam 5, and a rack 4 is provided on the top of the crossbeam 5. Two hole cutters 7 are movably connected to the tracks 3 on the crossbeam 5. Each hole cutter 7 also has a servo motor 6 fixed to its top, and the output gears of these servo motors 6 mesh with the rack 4 on the crossbeam 5. By operating the servo motors 6 on the top of the hole cutters 7, the hole cutters 7 can be driven to move bidirectionally on the tracks 3 of the crossbeam 5.

[0036] A laser head 8 is installed at the bottom of the hole cutting machine 7, with the end of the laser head 8 facing downwards. When the hole cutting machine 7 moves to the appropriate position, the laser head 8 emits a laser beam to cut holes in the speaker grille placed below.

[0037] A bellows cover 9 is fixed between the side of the hole cutter 7 and both ends of the crossbeam 5. The bellows cover 9 is movably connected to the top and front of the crossbeam 5 and can extend and retract as the crossbeam 5 and the hole cutter 7 move, thus playing a certain role in dust prevention and protecting the internal structure.

[0038] A 90-degree bent connector 10 is fixed to the other side of the hole cutter 7. Positioning holes 11 are provided at both ends and the bend of the connector 10. A pressure plate 12 is detachably connected to the front of the connector 10. A hexagonal socket head cap connector 13 is inserted into the corresponding position of the pressure plate 12, and the connector 13 is threaded into the positioning holes 11. A retractable elastic cover 14 made of fluororubber is sandwiched between the connector 10 and the pressure plate 12. The elastic cover 14 is located between the two hole cutters 7. The elastic cover 14 effectively prevents dust from entering the area between the two hole cutters 7, protecting components such as the track 3 and rack 4 on the crossbeam 5 and reducing dust-proof blind spots.

[0039] The working principle of this utility model is as follows: A certain audio equipment manufacturer needed to produce a large number of audio grilles with specific hole patterns, so it introduced this high-speed laser cutting device for audio grilles.

[0040] First, the staff places the speaker grille to be cut in a suitable position under the machine 1 to ensure that its position is accurate so that the laser head 8 can cut the hole accurately.

[0041] Next, the servo motor 6 at the top of the crossbeam 5 is started. The servo motor 6 drives the crossbeam 5 to move on the track 3 at the top of the machine body 2 through the meshing of the gear and rack 4, so that the crossbeam 5 reaches a horizontal position that is roughly suitable for the hole cutting operation.

[0042] Then, the servo motors 6 on top of the two hole cutters 7 are started respectively. These servo motors 6 drive the hole cutters 7 to move on the track 3 of the crossbeam 5, and adjust the position of the two hole cutters 7 so that their laser heads 8 are aligned with different positions on the speaker grille that need to be cut.

[0043] As the hole cutter 7 moves, the bellows cover 9 expands and contracts with the relative positions of the hole cutter 7 and the two ends of the crossbeam 5, maintaining protection for the internal structure at all times. At the same time, the elastic cover 14 between the two hole cutters 7 also expands and contracts according to the movement of the hole cutters 7, effectively preventing dust from entering the area.

[0044] Once the hole cutter 7 reaches the accurate position, the laser head 8 emits a high-energy laser beam to quickly cut holes in the speaker grille. Because dual hole cutters 7 operate simultaneously, the cutting efficiency is greatly improved; the cutting of multiple holes, which previously required sequential processing, can now be performed concurrently.

[0045] During the hole-cutting process, the elastic cover 14 always plays a dustproof role, preventing dust from falling onto the track 3 and rack 4 of the crossbeam 5, avoiding problems such as wear of track 3 and poor transmission of rack 4 due to dust accumulation, and ensuring the long-term stable operation of the device.

[0046] After the holes are cut, the workers remove the speaker grille with the holes cut, put in a new grille with holes to be cut, and repeat the above operation to continue the hole cutting production.

[0047] Compared with the prior art, the present invention has the following advantages: This high-speed laser cutting device for speaker grilles features a detachable elastic cover 14 between the two cutting machines 7. Made of fluororubber, the elastic cover 14 offers excellent elasticity and sealing. As the cutting machines 7 move, the elastic cover 14 expands and contracts with their changing positions, always tightly covering the area between the two machines, effectively preventing dust from entering. Simultaneously, the bellows cover 9 also provides dust protection for the area between the crossbeam 5 and the cutting machines 7. This dual dustproof design significantly reduces dust corrosion of critical transmission components such as the track 3 and rack 4, lowering the probability of wear and failure due to dust, extending the device's lifespan, and reducing maintenance costs.

[0048] The flexible cover 14's bending shape and stretchable characteristics allow it to better adapt to the movement trajectory of the hole cutter 7, covering areas that are difficult to reach with traditional dustproofing methods, reducing dust-proof blind spots. This ensures that key components inside the device are always in a relatively clean working environment, guaranteeing the stability of the device's operation and the accuracy of the hole cutting.

[0049] The elastic cover 14 is detachably connected to the connector 10 via a pressure plate 12 and a connector 13 in the form of hexagonal screws. When the elastic cover 14 is damaged or needs cleaning, workers can easily remove it for replacement or cleaning and then reinstall it. This detachable design greatly improves the ease of maintenance of the device and reduces maintenance time and costs.
