[0043] Please refer to Figures 1 to 4 This application provides a frame assembly 10 for a laser processing equipment, the frame assembly 10 including a fan device 22, a frame 11 and a first baffle 21.

[0044] In this embodiment, the fan device 22 is used to provide wind power. The fan device 22 has a first electrical connection portion 226, and the frame 11 has a receiving channel 111 extending through the frame 11. The fan device 22 is disposed within the receiving channel 111. The receiving channel 111 accommodates and supports the fan device 22, and the inner wall of the receiving channel 111 has a second electrical connection portion 114. When the fan device 22 is installed within the receiving channel 111, the first electrical connection portion 226 is electrically connected to the second electrical connection portion 114. A first baffle 21 is detachably connected to the frame 11 and abuts against the first side of the fan device 22.

[0045] To facilitate fan and air duct cleaning, related technologies involve removing and installing fans by unscrewing screws. This process involves removing the fan from the screws, disconnecting the terminals, and then cleaning the fan, which is cumbersome and inefficient. In contrast, this application allows for quick installation of the fan assembly 22 by placing it into the receiving channel 111 of the frame 11 and then detachably attaching the first baffle 21 to the frame 11, which holds the fan assembly 22 from the other side. When disassembling the fan assembly 22, the first baffle 21 is removed, and the fan assembly 22 is taken out of the receiving channel 111, thus improving the efficiency of fan assembly and maintenance.

[0046] In some embodiments of this application, the rack assembly 10 includes a second baffle 12, which is detachably connected to the frame 11 and located on the second side of the fan assembly 22. The second side is the air inlet side of the fan assembly 22, and the first side is the air outlet side of the fan assembly 22. The second baffle 12 can be used to intercept some dust or debris, and / or block light.

[0047] In some embodiments of this application, the frame 11 is further provided with an air inlet channel 117, which is located on the air inlet side of the fan device 22, and the second baffle 12 is provided at the channel opening of the air inlet channel 117 on the side away from the fan device 22.

[0048] In one specific embodiment, the rack assembly 10 includes a second baffle 12, the air inlet channel 117 has a first receiving slot 118 at its opening, the second baffle 12 is detachably connected to the first receiving slot 118, and the second baffle 12 is located on the air inlet side of the fan device 22.

[0049] In one specific embodiment, the opening area of ​​the air inlet channel 117 gradually increases in the direction away from the fan device 22, thereby enabling air to be drawn in through a larger opening and improving the exhaust effect.

[0050] In this embodiment, the second baffle 12 includes a frame 121 and a plurality of baffles 122 arranged at intervals within the frame 121, the frame 121 being disposed on the frame 11. The projections of the plurality of baffles 122 in the ventilation direction F1 of the fan device 22 are spaced apart. By providing the second baffle 12, foreign objects in the laser processing area can be prevented from entering the fan device 22, thereby protecting the fan device 22. The spaced projections of the plurality of baffles 122 in the ventilation direction F1 of the fan device 22 enable better ventilation.

[0051] In some embodiments of this application, the second baffle 12 can be detachably connected to the first receiving groove 118 by means of magnetic connection, snap-fit ​​connection or other means.

[0052] In some embodiments of this application, the first baffle 21 includes a plate body 211 and an elastic buckle 212 disposed on one side of the plate body 211. The plate body 211 is received in a receiving channel 111, and the elastic buckle 212 elastically abuts against the inner wall of the receiving channel 111 to engage the first baffle 21 in the receiving channel 111.

[0053] In one specific embodiment, a second receiving groove 113 is formed on the inner wall of the receiving channel 111. A first baffle 21 is detachably connected to the second receiving groove 113. The first baffle 21 is located on the air outlet side of the fan device 22, and a second through hole 213 is formed on the first baffle 21. The plate body 211 is received in the second receiving groove 113, and an elastic buckle 212 abuts against the inner wall of the second receiving groove 113 to snap the first baffle 21 into the second receiving groove 113. In other embodiments, the first baffle 21 can be magnetically connected to the second receiving groove 113, which is not limited in this application. By setting the first baffle 21, the fan device 22 can be fixed, preventing the first electrical connection part 226 and the second electrical connection part 114 of the fan device 22 from falling off when the fan device 22 is working.

[0054] In some embodiments of this application, the inner wall of the receiving channel 111 is provided with a boss 115, and a second electrical connection portion 114 is provided on the boss 115. The first electrical connection portion 226 is the power input terminal of the fan device 22. The first electrical connection portion 226 can be connected to a power source to provide power input. The boss 115 is provided with a second electrical connection portion 114 that cooperates with the first electrical connection portion 226. The second electrical connection portion 114 is the power output terminal. The first electrical connection portion 226 and the second electrical connection portion 114 are detachably connected and electrically connected. When the first electrical connection portion 226 and the second electrical connection portion 114 are connected, the second electrical connection portion 114 supplies power to the fan device 22 through the first electrical connection portion 226.

[0055] The rack assembly of this application allows the fan device 22 to be placed in the receiving channel 111, and the first electrical connection 226 and the second electrical connection 114 to be connected, thus fixing the fan device 22 to the frame 11. Simultaneously, the fan device 22 is connected to power through the first electrical connection 226 and the second electrical connection 114. When it is necessary to disassemble the fan device 22, it can be removed from the receiving channel 111, enabling quick installation and disassembly of the fan device 22 and improving the efficiency of fan device assembly and disassembly. Furthermore, the receiving channel 111 is used to accommodate and support the fan device 22, and the first electrical connection 226 and the second electrical connection 114 do not need to bear the weight of the fan device 22 after connection, thus improving the stability of the connection between the first electrical connection 226 and the second electrical connection 114.

[0056] In this embodiment, the first electrical connection part 226 is one of the connector male and connector female, and the second electrical connection part 114 is the other of the connector male and connector female, and the connector male and connector female are plugged in.

[0057] In one specific embodiment, the first electrical connection portion 226 is a male connector socket, and the second electrical connection portion 114 is a female connector socket. The first electrical connection portion 226 is inserted into the second electrical connection portion 114 to form a detachable connection and electrical connection. In other embodiments, the first electrical connection portion 226 and the second electrical connection portion 114 can be spring pins or spring sheets, etc., depending on the specific situation.

[0058] In another specific embodiment, the first electrical connection portion 226 is a female connector socket, and the second electrical connection portion 114 is a male connector socket. The second electrical connection portion 114 is inserted into the first electrical connection portion 226 to form a detachable connection and an electrical connection.

[0059] Combination Figures 5 to 9 In some embodiments of this application, the fan device 22 includes a housing 222, a fan module 221 located inside the housing 222, and a light-blocking grille 225. The light-blocking grille 225 is connected to the housing 222 and located on the air intake side of the fan module 221. The light-blocking grille 225 includes a plurality of spaced first grilles 228, and the surfaces of the plurality of first grilles 228 are set at an angle to the ventilation direction of the fan device 22.

[0060] In this embodiment, the light-blocking grille 225 includes a plurality of spaced-apart first grille bars 228, the surfaces of which form a preset angle with the ventilation direction of the fan device 22. The preset angle can be 30 degrees, 60 degrees, etc., and can be set according to specific circumstances. The proportion of the pore area on the union projection of the projections of the plurality of first grille bars 228 onto the ventilation direction F1 of the fan device 22 is not greater than a preset ratio.

[0061] The preset ratio can be 0, 10%, 5%, or other values. When the preset ratio is 0, there are no gaps on the projected union, resulting in the best light-blocking effect. When light shines along the ventilation direction F1 onto the light-blocking grille 225, the light cannot pass directly through the grille 225, thus achieving the light-blocking function. When the preset ratio is 10%, 5%, or other values ​​greater than 0, it can block some light. The preset ratio can be set according to the light-blocking and ventilation requirements.

[0062] Since the multiple first grid bars 228 are spaced apart, ventilation can be achieved. At the same time, the union projection of the multiple first grid bars 228 on the ventilation direction F1 of the fan device 22 is not greater than a preset ratio. When light shines on the light-blocking grid 225 along the ventilation direction F1, the light cannot pass directly through the light-blocking grid 225, thereby achieving the light-blocking effect.

[0063] In one specific embodiment, the first grid strip 228 is rectangular, and the surfaces of multiple spaced-apart first grid strips 228 are parallel, with the surfaces of the multiple first grid strips 228 forming an angle with the ventilation direction F1 of the fan device 22. The projections of the two side edges of the first grid strip 228 onto the ventilation direction F1 are respectively located within the projections of the two adjacent first grid strips 228. In other embodiments, the first grid strip 228 may also be trapezoidal, arc-shaped, or irregular in shape, depending on the specific circumstances.

[0064] In some embodiments of this application, one side of the housing 222 is rotatably connected to a light-blocking grille 225, which is located on the air intake side of the fan module 221. The light-blocking grille 225, located on the air intake side of the fan module 221, can block light and allow ventilation. Since the air velocity on the air intake side of the fan module 221 is lower than that on the air outlet side, this application places the light-blocking grille 225 on the air intake side of the fan module 221, resulting in lower noise in the frame assembly 10 when the fan device 22 is operating. The rotatable connection between one side of the housing 222 and the light-blocking grille 225 allows the light-blocking grille 225 to be opened for maintenance of the fan module 221.

The clamping member 243 is engaged with the optical shaft 241 to clamp the first bushing 2251 and the second bushing 2231. The clamping member 243 can be a retaining spring, a limiting ring, a set screw, or a nut, etc.

[0066] In one specific embodiment, there are two clamping members 243, with a first bushing 2251 and a second bushing 2231 located between the two clamping members 243. In some embodiments, two second bushings 2231 are provided on one side of the housing 222, with the first bushing 2251 located between the two second bushings 2231 and the two second bushings 2231 located between the two clamping members 243.
