Description

Technical Field

[0001] This application relates to the field of laser processing technology, specifically to a frame assembly and laser processing equipment. Background Technology

[0002] When laser processing equipment engraves wood products, a certain amount of smoke is generated. If this smoke is not removed from the processing area in a timely manner, it will absorb laser energy, thus affecting the engraving quality and efficiency. Therefore, equipping the machine with a fan to remove the smoke generated during processing is particularly important, as this can effectively ensure processing quality.

[0003] However, during the use of laser processing equipment, dust can enter the back space of the equipment through the fan, and the back space contains many electronic components that are difficult to clean. Utility Model Content

[0004] The purpose of this application is to provide a frame assembly and laser processing equipment for laser processing equipment, so as to reduce dust entering the back space of the laser processing equipment through the fan, effectively alleviate the problem of reduced lifespan of electronic components in the back space caused by dust accumulation, thereby improving the stability of the equipment and extending its service life.

[0005] This application provides a frame assembly for a laser processing equipment. The frame assembly includes: a support plate; a housing, which is disposed opposite to the support plate, and the support plate and the housing form a receiving space; and a fan assembly located within the receiving space. The fan assembly includes a fan housing and a fan. The fan housing is mounted on one side of the support plate or the housing and has a mounting cavity. The fan is located within the mounting cavity, which has a first air inlet and a first air outlet. The support plate has a second air inlet corresponding to the first air inlet, and the housing has a second air outlet corresponding to the first air outlet. One end face of the fan housing is sealed to the end face of the support plate, and the other end face of the fan housing is sealed to the end face of the housing.

[0006] The fan's air inlet faces the first air inlet, and the first air inlet connects the fan's air inlet and the second air inlet; the fan's air outlet faces the first air outlet, and the first air outlet connects the fan's air outlet and the second air outlet.

[0007] The fan assembly also includes a first seal, which is located between the cavity surface of the mounting cavity where the first air inlet is provided and the fan, and is arranged around the outer edge of the first air inlet.

[0008] The fan assembly also includes a second seal, which is located on the side of the fan away from the first air inlet and is arranged around the outer edge of the fan's air outlet. The two end faces of the second seal are in contact with the inner surfaces of the fan and the housing, respectively.

[0009] The fan housing has a notch at the end facing the housing, and the outer peripheral sidewall of the second seal protrudes to form a positioning part. The positioning part is adapted to the notch and is located inside the notch.

[0010] The rack assembly also includes a connector seat located outside the receiving space and fixed at the edge of the fan's air outlet corresponding to the position of the second air outlet. The second seal is clamped between the air outlet connector seat and the fan. The connector seat has a protrusion on the side facing the second seal, and the protrusion presses against the second seal.

[0011] The rack assembly also includes a circuit board located within the housing space and outside the mounting cavity; the fan assembly also includes a fan connection cable that electrically connects the circuit board and the fan.

[0012] The circuit board has a clearance opening, the fan housing is located inside the clearance opening, and the circuit board is fixed to the fan housing.

[0013] The outer peripheral sidewall of the fan housing is provided with a baffle. The baffle protrudes from the outer peripheral sidewall and surrounds the outer peripheral sidewall. The width of the baffle along the depth direction of the mounting cavity is smaller than the width of the sidewall of the mounting cavity along the depth direction of the mounting cavity, so that a gap is formed between the baffle and the support plate.

[0014] This application embodiment also provides a laser processing device, which includes: a frame assembly of any of the above; a protective cover, installed on the frame assembly and forming a processing chamber with the frame assembly, the processing chamber and the receiving space being located on opposite sides of a support plate, and a second air inlet connecting the processing chamber and the receiving space; and a laser head assembly, installed on the frame assembly, the laser head assembly being used to perform laser processing on the workpiece to be processed in the processing chamber.

[0015] The beneficial effects of this application are as follows: The frame assembly and laser processing equipment provided in this application include a support plate and a housing, and a fan assembly, which are arranged opposite to each other. The support plate and the housing form a receiving space, and the fan assembly is located within the receiving space, including a fan housing and a fan. Specifically, the fan housing is installed on one side of the support plate or the housing, and the fan housing has a mounting cavity. The fan is located within the mounting cavity, and the mounting cavity has a first air inlet and a first air outlet. Furthermore, the support plate has a second air inlet corresponding to the first air inlet, and the housing has a second air outlet corresponding to the first air outlet. One end face of the fan housing is sealed to the end face of the support plate, and the other end face of the fan housing... The side end face and the end face of the housing are sealed. Thus, by embedding the fan inside the fan housing and sealing the fan housing relatively within the back space of the laser processing equipment (i.e., the receiving space formed by the support plate and the housing), the fan is isolated from the back space through the fan housing. This makes it difficult for airflow to enter the back space of the laser processing equipment when the fan is working, and thus it is difficult to bring dust in. This effectively alleviates the problem of dust accumulation in the back space affecting the service life of electronic components in the back space due to the difficulty in cleaning dust. Therefore, it can protect the back space of the laser processing equipment, improve the stability of the laser processing equipment, and extend the service life of the equipment.

Figure 7 This is a three-dimensional structural diagram of the fan assembly, support plate, and housing provided in the embodiments of this application.

[0025] like Figures 1 to 7As shown, the laser processing equipment 10 includes a frame assembly 20, a protective cover 30, and a laser head assembly 40 mounted on the frame assembly 20. The frame assembly 20 includes a support plate 21 and a housing 22 disposed opposite to each other, and a fan assembly 23. The support plate 21 and the housing 22 form a receiving space R1, which is located between the support plate 21 and the housing 22. The fan assembly 23 is located within the receiving space R1. The protective cover 30 and the frame assembly 20 form a processing chamber R2. The processing chamber R2 and the receiving space R1 are located on opposite sides of the support plate 21, and the space within the processing chamber R2 communicates with the receiving space R1. The laser head assembly 40 is used to perform laser processing on the workpiece to be processed within the processing chamber R2.

[0026] Specifically, such as Figures 6 to 10 As shown, in the frame assembly 20 of the laser processing equipment 10 described above, the fan assembly 23 may include a fan housing 231 and a fan 232. The fan housing 231 is mounted on one side of the support plate 21 or the rear shell 22, and the fan housing 231 has a mounting cavity 2311. The fan 232 is located within the mounting cavity 2311, and the mounting cavity 2311 has a first air inlet 2311B and a first air outlet 2311C. For example, as... Figures 6 to 10 As shown, the fan housing 231 can be specifically installed on one side of the support plate 21, for example, it can be fixed to one side of the support plate 21 by screws, and the mounting cavity 2311 can be specifically opened on the side of the fan housing 231 away from the support plate 21. The first air inlet 2311B and the first air outlet 2311C can be respectively opened at opposite ends of the mounting cavity 2311 along the depth direction of the mounting cavity 2311. Thus, by embedding the fan 232 inside the fan housing 231, the fan 232 is isolated from the back space of the laser processing equipment 10 (i.e., the aforementioned accommodating space R1) through the fan housing 231. This allows the fan housing 231 to prevent dust from entering the back space through the fan 232. Therefore, compared to the related art where the fan 232 is directly exposed to the back space of the laser processing equipment 10, the method of embedding the fan 232 inside the fan housing 231 in this embodiment can reduce the amount of dust entering the back space of the laser processing equipment 10. This effectively alleviates the problem of dust accumulation in the back space affecting the service life of electronic components in the back space due to the difficulty in cleaning the dust in the back space, improves the stability of the laser processing equipment 10, and extends the service life of the equipment.

[0027] In this embodiment, as Figure 5 and Figure 7As shown, the support plate 21 can be provided with a second air inlet 211 corresponding to the first air inlet 2311B. The second air inlet 211 is connected to the first air inlet 2311B, thereby enabling the space inside the processing chamber R2 of the laser processing equipment 10 to be connected to the first air inlet 2311B through the second air inlet 211. Figure 4 and Figure 7 As shown, the housing 22 may be provided with a second air outlet 221 corresponding to the first air outlet 2311C. The second air outlet 221 is connected to the first air outlet 2311C, thereby enabling the external space of the laser processing equipment 10 to be connected to the first air outlet 2311C through the second air outlet 221. In this way, it is ensured that the smoke generated in the processing chamber R2 of the laser processing equipment 10 can be discharged to the outside of the laser processing equipment 10 in sequence through the second air inlet 211, the first air inlet 2311B, the fan 232, the first air outlet 2311B, and the second air outlet 211.

[0028] Furthermore, one end face of the fan housing 231 (for example, the end face of the fan housing 231 with the first air inlet 2311B) can be sealed with the end face of the support plate 21, and the other end face of the fan housing 231 (for example, the end face of the fan housing 231 with the first air outlet 2311C) can be sealed with the end face of the housing 22. This allows the fan housing 231 to be relatively sealed within the accommodating space R1 formed by the support plate 21 and the housing 22, ensuring that the fan 232 is isolated from the accommodating space R1 through the fan housing 231. Therefore, when the fan 232 is working, it is not easy for airflow to enter the back space of the laser processing equipment 10, and thus it is not easy to bring dust in. This can further alleviate the problem that the accumulation of dust in the back space affects the service life of electronic components in the back space due to the difficulty in cleaning the dust in the back space, further improve the stability of the laser processing equipment 10, and further extend the service life of the equipment.

[0029] Specifically, such as Figure 6 and Figure 9 As shown, the air inlet 232A of the fan 232 can be positioned facing the first air inlet 2311B, and the first air inlet 2311B can connect the air inlet 232A of the fan 232 with the second air inlet 211. The air outlet 232B of the fan 232 can be positioned facing the first air outlet 2311C, and the first air outlet 2311C can connect the air outlet 232B of the fan 232 with the second air outlet 221. This facilitates the fan 232 drawing in the smoke generated in the processing chamber R2 through the second air inlet 211 and the first air inlet 2311B, and then discharging it to the outside of the laser processing equipment 10 through the first air outlet 2311C and the second air outlet 221, forming a complete airflow circulation path. This design not only improves the smoke extraction efficiency but also effectively prevents dust accumulation in the accommodating space R1.

[0030] In this embodiment, the air inlet 232A of the fan 232 and the first air inlet 2311B can be sealed and connected to ensure the sealing performance of the air inlet side of the fan assembly 23, increase the suction power of the fan 232, and thus improve the smoke exhaust efficiency.

[0031] Specifically, such as Figure 8 As shown, to achieve airtightness on the air inlet side of the fan assembly 23, the fan assembly 23 further includes a first sealing member 233. The first sealing member 233 is located between the cavity surface 2311A of the mounting cavity 2311 where the first air inlet 2311B is opened and the fan 232, and can be arranged around the outer edge of the first air inlet 2311B. The air inlet 232A of the fan 232 and the first air inlet 2311B can be sealed and connected through the first sealing member 233. Furthermore, in a specific implementation, when the fan 232 is assembled in the mounting cavity 2311, the first sealing member 233 can fit tightly in the gap between the outer edge of the first air inlet 2311B and the outer edge of the air inlet 232A of the fan 232, thereby increasing the suction power of the fan 232 and improving the smoke extraction efficiency.

[0032] In some examples, such as Figure 8 As shown, the first sealing element 233 can be an annular sealing element 233 arranged around the outer edge of the first air inlet 2311B. For example, the annular sealing element 233 can be specifically formed by splicing two semi-annular sealing elements.

[0033] The material of the first sealing element 233 can be silicone or foam (e.g., EVA foam). For example, the annular sealing element 233 can be an annular foam, and the semi-annular sealing element can be a semi-annular foam.

[0034] In this embodiment, the outer edge of the air outlet 232B of the fan 232 can be sealed to the outer edge of the first air outlet 2311C, and the air outlet 232B of the fan 232 can be sealed to the second air outlet 211, so as to ensure the airtightness of the air outlet side of the fan assembly 23 and effectively prevent dust from entering the above-mentioned accommodating space R1 through the air outlet side of the fan assembly 23.

[0035] Specifically, such as Figure 8As shown, in order to achieve the airtightness of the air outlet side of the fan assembly 23, the fan assembly 23 may also include a second seal 234. The second seal 234 is located on the side of the fan 232 away from the first air outlet 2311C and is arranged around the outer edge of the air outlet 232B of the fan 232. The two end faces of the second seal 234 (for example, the end face of the second seal 234 facing the fan 232 and the end face of the second seal 234 away from the fan 232) can respectively contact the inner surface of the fan 232 and the housing 22. Furthermore, in specific implementation, when the fan 232 is assembled in the mounting cavity 2311, the second sealing member 234 can not only fit tightly in the gap between the outer edge of the second air outlet 221 and the outer edge of the air outlet 232B of the fan 232, so as to achieve a sealed connection between the air outlet 232B of the fan 232 and the second air outlet 221 through the second sealing member 234, but also seal the outer edge of the air outlet 232B of the fan 232 and the outer edge of the first air outlet 2311C of the mounting cavity 2311, so that the fan 232 only exposes its air outlet 232B on the air outlet side of the fan assembly 23. This not only effectively prevents dust and other impurities from entering the accommodating space R1, thereby improving the cleanliness of the back space of the laser processing equipment 10, but also increases the suction power of the fan 232.

[0036] In some examples, such as Figure 8 As shown, the second seal 234 can specifically be an annular seal 234 arranged around the outer edge of the air outlet 232B of the fan 232.

[0037] The material of the second sealing element 234 can be silicone or foam (e.g., EVA foam). For example, the annular sealing element 234 can be an annular sealing gasket (e.g., an annular silicone gasket).

[0038] Furthermore, in specific implementation, the aforementioned fan assembly 23 may include both a first seal 233 and a second seal 234, and the first seal 233, the fan 232, and the second seal 234 may be sequentially installed into the mounting cavity 2311 of the fan housing 231 to complete the assembly of the aforementioned fan assembly 23. Thus, the fan 232 can be isolated from the external space of the fan housing 231 within the internal space of the fan housing 231, achieving the effects of dust prevention and sealing. Moreover, the good sealing performance of the front and rear of the fan 232 can increase the suction power of the fan 232.

[0039] In some embodiments, such as Figure 6 and Figure 9 As shown, the side wall of the fan housing 231 facing the housing 22 may be provided with a notch 231A, and the depth direction of the notch 231A is parallel to the depth direction of the mounting cavity 2311.

[0040] Furthermore, in the above-described embodiment where the fan assembly 23 also includes a second seal 234, as shown... Figure 6 As shown, the outer peripheral sidewall of the second seal 234 can protrude to form a positioning portion 2341, which is adapted to the notch 231A and is located within the notch 231A. In this way, during the assembly of the fan assembly 23, the second seal 234 and the fan housing 231 can be quickly positioned, thereby facilitating the assembly of the fan assembly 23.

[0041] Specifically, the width of the positioning part 2341 can be adapted to the width of the notch 231A so that the notch 231A on the fan housing 231 prevents the positioning part 2341 of the second seal 234 from moving along its width direction.

[0042] In some specific embodiments, such as Figure 11 As shown, the rack assembly 20 may further include a circuit board 25, which is located within the receiving space R1 and outside the mounting cavity 2311. Furthermore, the fan assembly 23 may also include a fan connection cable (not shown in the figure), which electrically connects the circuit board to the fan 232 to facilitate power supply and control of the fan 232.

[0043] Specifically, the circuit board 25 may have a clearance opening 251, and the fan housing 231 may be located within the clearance opening 251. The circuit board 231 can be fixed to the fan housing 231, thereby achieving a compact layout of the circuit board 25 and the fan housing 231. This saves space and ensures neat routing of the fan connection wires, avoiding potential safety hazards caused by messy wiring. In practical applications, the size of the clearance opening 251 on the circuit board 25 can be customized according to the specific dimensions of the fan housing 231 to ensure a tight fit between the two. In addition, the circuit board 25 can also be securely installed on the fan housing 231 with screws or other fasteners to prevent loosening due to vibration or external forces during use.

[0044] Specifically, one end of the fan connection cable can be electrically connected to the lower side of the fan 232 inside the mounting cavity 2311, and the other end can pass through a pre-drilled hole on the fan housing 231 and be electrically connected to the circuit board outside the mounting cavity 2311, thereby enabling the fan connection cable to connect to the circuit board from below the fan 232. The through hole can be positioned corresponding to the lower side of the fan 232 to reduce the required length of the fan connection cable.

[0045] Furthermore, in the above embodiment where a notch 231A is provided at the end of the side wall of the fan housing 231 facing the housing 22, the notch 231A can serve as a through hole reserved on the fan housing 231 for the fan connection wire to pass through, thereby enabling the notch 231A to have both positioning and wire passing functions.

[0046] In some examples, the circuit board described above can specifically be a PCB (printed circuit board). The fan connection cable described above can specifically be a wire.

[0047] In some embodiments, such as Figures 1 to 8 As shown, the rack assembly 20 may also include a connector 24 located outside the receiving space R1 and fixed to the edge of the air outlet 232B of the fan 232 at the position corresponding to the second air outlet 221. For example, the edge of the air outlet 232B of the fan 232 can be fixed to the position corresponding to the second air outlet 221 by screws.

[0048] Specifically, in the above embodiment where the fan assembly 23 further includes a second seal 234, such as Figure 6 As shown, the second seal 234 can be clamped between the connector seat 24 and the fan 232, and the side of the connector seat 24 facing the second seal 234 can be provided with a protrusion, which can press against the second seal 234 to achieve a sealed connection between the air inlet of the connector seat 24 and the air outlet 232B of the fan 232.

[0049] For example, the protrusion on the connector seat 24 can be a rib, and the rib can be annular. The connector seat 24 can specifically be a tracheal connector seat.

[0050] In some embodiments, such as Figures 9 to 11 As shown, a baffle 231B may protrude from the outer peripheral sidewall of the fan housing 231. The baffle 231B protrudes from and surrounds the outer peripheral sidewall of the fan housing 231. Furthermore, the width of the baffle 231B along the depth direction of the mounting cavity 2311 may be smaller than the width of the sidewall of the mounting cavity 2311 along the depth direction of the mounting cavity 2311, so that a gap is formed between the baffle 231B and the support plate 21. This gap can serve as a channel for the wire harness, thereby facilitating wire routing and preventing the wire harness from affecting the assembly of the fan assembly 23.

[0051] Furthermore, in the aforementioned embodiment where the rack assembly 20 also includes a circuit board 25, as shown... Figure 11 As shown, the circuit board 25 can be mounted on the baffle 231B, for example, it can be fixed to the baffle 231B with screws.

[0052] For example, the surface of the baffle 231B may be provided with a rib protrusion J1. The rib protrusion J1 can be used to enhance the structural strength of the baffle 231B, and can also serve as a limiting structure to limit the circuit board 25 mounted on the baffle 231B, thereby further improving the reliability of the equipment.

[0053] In the above embodiments, such as Figures 1 to 5As shown, the frame assembly 20 may also include a base plate 26, a support plate 21 and a housing 22 connected to the same side (e.g., the upper side) of the base plate 26, thereby enabling the base plate 26 to provide bottom-up support to the support plate 21 and the housing 22.

[0054] Specifically, such as Figures 1 to 4 As shown, the support plate 21 and the housing 22 can be arranged opposite each other in a direction parallel to the base plate 26. The frame assembly 20 may also include a top cover 27, which covers the top of the receiving space R1 and seals the top opening of the receiving space R1.

[0055] As can be seen from the above, the frame assembly of the laser processing equipment provided in this embodiment includes a support plate and a housing, and a fan assembly, which are arranged opposite to each other. The support plate and the housing form a receiving space, and the fan assembly is located within the receiving space, including a fan housing and a fan. Specifically, the fan housing is installed on one side of the support plate or the housing, and the fan housing has a mounting cavity. The fan is located in the mounting cavity, and the mounting cavity has a first air inlet and a first air outlet. Furthermore, the support plate has a second air inlet corresponding to the first air inlet, and the housing has a second air outlet corresponding to the first air outlet. One end face of the fan housing is sealed to the end face of the support plate, and the other end face of the fan housing is sealed to the end face of the housing. By embedding the fan inside the fan housing and sealing the fan housing relatively within the back space of the laser processing equipment (i.e., the receiving space formed by the support plate and the housing), the fan is isolated from the back space through the fan housing. This prevents airflow from easily entering the back space of the laser processing equipment during fan operation, thus reducing the likelihood of dust being brought in. This effectively alleviates the problem of dust accumulation in the back space affecting the lifespan of electronic components due to the difficulty in cleaning dust in the back space. Therefore, it can protect the back space of the laser processing equipment, improve the stability of the laser processing equipment, and extend the service life of the laser processing equipment.
