[0015] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0016] like Figure 1-Figure 6 As shown, it is a structural diagram of a laser hair removal device optical module shell spraying device provided by an embodiment of the present invention, comprising a housing 1, a longitudinal rotating shaft 2, a multi-stage pressing mechanism 100, a bidirectional adjustment mechanism 200, a transmission unit and an adaptive closing mechanism 300, wherein the longitudinal rotating shaft 2 is rotatably installed in the housing 1; the multi-stage pressing mechanism 100 is arranged at the bottom end of the longitudinal rotating shaft 2, and is used to realize the fixing work of multiple optical module shells 8, and when the longitudinal rotating shaft 2 rotates, the optical module shells 8 at multiple positions are driven to rotate synchronously through the arranged multi-stage pressing mechanism 100; the bidirectional adjustment mechanism 200 is arranged on both sides of the longitudinal rotating shaft 2, and the bidirectional adjustment mechanisms 200 on both sides are offset by one The workstation is arranged, and moves synchronously in the height direction when the longitudinal shaft 2 rotates; the transmission unit is installed between the longitudinal shaft 2 and the two-way adjustment mechanism 200, so as to drive the longitudinal shaft 2 and the two-way adjustment mechanism 200 to move synchronously at the same time; the adaptive closing mechanism 300 is installed at the end of the transverse rod 12 of the two-way adjustment mechanism 200 on both sides, and the adaptive closing mechanism 300 moves synchronously with the two-way adjustment mechanism 200, and passes over multiple optical module shells 8 in sequence during the movement; wherein, a feeding unit and a drying unit are also installed at the bottom end of the box body 1, and the feeding unit and the drying assembly are respectively connected to the adaptive closing mechanism 300 on both sides, so as to facilitate synchronous drying after spraying.
[0017] In one example of the present invention, the vertical axis 3 at the bottom is plugged into a base 29 arranged in the box body 1, and the motor 19 is electrically connected to an external controller 30 for controlling the spraying process, so that the optical module shell 8 can rotate and spray evenly while automatically drying the optical module shell 8 of the previous workstation evenly.
[0018] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the multi-stage pressing mechanism 100 includes a vertical shaft 3, a limiting groove 4, an elastic support member 5, a baffle 6 and a suction cup 7; The vertical shafts 3 are arranged longitudinally in the box body 1, and the bottom ends of the middle vertical shafts 3 are all equipped with suction cups 7 for fixing the optical module housing 8; Among them, a limiting groove 4 is opened on the vertical axis 3 at the top, the vertical axis 3 and the limiting groove 4 are both slidably connected with the longitudinal rotating axis 2, and a baffle 6 is fixedly installed at the bottom of the vertical axis 3, and an elastic support member 5 is sleeved on the vertical axis 3 between the longitudinal rotating axis 2 and the baffle 6.
[0019] In one embodiment of the present invention, the vertical axis 3 at the bottom is inserted into the base 29. After the optical module shell 8 is placed, the suction cup 7 at the bottom of the vertical axis 3 is used to adsorb it. The above process is repeated in sequence to fix multiple optical module shells 8. However, it is necessary to ensure that the center of gravity of the multiple optical module shells 8 is on the same axis as the longitudinal rotating shaft 2. When the sprayed optical module shell 8 needs to be removed, the baffle 6 is pushed upward, and the vertical axis 3 and the limit groove 4 slide along the longitudinal rotating shaft 2, and the elastic support member 5 is compressed by force.

[0021] In one example of the present invention, the driving screws 9 on both sides can push the screw sleeve 11 and the transverse rod 12 to move in the height direction when rotating, wherein the transverse rod 12 slides along the guide groove 13 set in the guide rail 10. When the transverse rod 12 passes through different sections of the guide groove 13, the transverse rod 12 slides laterally along the screw sleeve 11, and the elastic support member 14 is elastically deformed under the force.
[0022] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the transmission unit includes a driving gear 15, a connecting gear 16, a driven gear 17 and an inner shell 18; The inner shell 18 is fixedly mounted on the inner side of the top of the housing 1, and a driving gear 15, a connecting gear 16 and a driven gear 17 are arranged in the inner shell 18; The driving gear 15 is fixedly mounted on the end of the longitudinal rotating shaft 2 , the driven gear 17 is fixedly mounted on the end of the driving screw 9 , and the adjacent driving gears 15 and driven gears 17 are transmission-connected via a connecting gear 16 .
[0023] In one embodiment of the present invention, the driving screw 9 or the longitudinal rotating shaft 2 can be optionally used as the driving shaft to be connected to the shaft end of the external motor 19 through a coupling. When the driving screw 9 is connected to the motor 19, due to the meshing of the adjacent driving gear 15, connecting gear 16 and driven gear 17, the longitudinal rotating shaft 2 and the driving screw 9 at other positions can be driven to rotate synchronously through the driven gear 17, connecting gear 16 and driving gear 15 in turn; in addition, in addition to the above-mentioned gear transmission, the driving gear 15, connecting gear 16 and driven gear 17 can also be transmitted by sprocket and chain or pulley and synchronous belt, which will not be described one by one here.

[0025] In one example of the present invention, when the fixed block 20 and the pusher claw 21 enter between adjacent optical module housings 8, in the initial entry stage, the elastic support member three 22 is compressed and deformed by the force, and the two sides of the pusher claw 21 are in contact with the side surfaces of the optical module housing 8, and are in continuous contact with the top and bottom surfaces of the optical module housing 8 when the optical module housing 8 rotates. After the pusher claw 21 is separated from the optical module housing 8, the elastic support member three 22 returns to its original state under the action of the elastic force and pushes the pusher claws 21 on both sides to swing in the opposite direction along the fixed block 20.
[0026] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the feeding unit includes a liquid supply box 25 and a liquid delivery pipe 26, and the drying unit includes a drying box 27 and an air delivery pipe 28; The liquid supply box 25 and the drying box 27 are both installed on the inner side of the bottom of the box body 1, wherein the liquid supply box 25 is connected to the flow channel 24 on one side through the liquid supply pipe 26, and the drying box 27 is connected to the flow channel 24 on the other side through the air supply pipe 28.

[0028] In summary, the vertical shaft 3 at the bottom is plugged into the base 29. After the optical module housing 8 is placed, the suction cup 7 at the bottom of the vertical shaft 3 is used to adsorb it. The above process is repeated in sequence to achieve the fixation of multiple optical module housings 8. When the driving screw 9 is connected to the motor 19, due to the meshing of the adjacent driving gear 15, the connecting gear 16 and the driven gear 17, the longitudinal rotating shafts 2 at other positions and the driving screw 9 can be driven to rotate synchronously through the driven gear 17, the connecting gear 16 and the driving gear 15 in sequence. The driving screws 9 on both sides can push the screw sleeve 11 and the transverse rod 12 to move in the height direction when rotating, wherein the transverse rod 12 slides along the guide groove 13 provided in the guide rail 10. When the transverse rod 12 passes through different sections of the guide groove 13, the transverse rod 12 slides transversely along the screw sleeve 11, and the elastic support member 2 14 is elastically deformed by force. When the fixing block 20 and the pusher claw 21 enter between the adjacent optical module housings 8, in the initial entry stage, the elastic support member 3 22 is compressed and deformed by the force. The two sides of the pusher claw 21 are in contact with the side surfaces of the optical module housing 8, and are in continuous contact with the top and bottom surfaces of the optical module housing 8 when the optical module housing 8 rotates. After the pusher claw 21 is separated from the optical module housing 8, the elastic support member 3 22 is restored to its original state under the action of the elastic force. The spraying liquid can flow along the liquid supply box 25, the liquid infusion pipe 26 and the flow channel 24 under the action of the built-in pump body, and finally sprayed from the spray hole 23 on the left side to the top and bottom surfaces of the optical module housing 8, and after the pusher claw 21 is separated, sprayed to the outer side of the optical module housing 8, the hot air flows along the drying box 27, the gas supply pipe 28 and the flow channel 24 on the right side, and finally sprayed from the spray hole 23 on the right side to the surface of the optical module housing 8; the spraying device can realize the spraying of multiple optical module housings 8 at one time, improve the efficiency of spraying, and can accurately control the spraying spacing during the spraying process to ensure that both regular and irregular surfaces can be sprayed evenly, so as to achieve the purpose of controlling the spraying quality, and can simultaneously perform the fixed-point drying work during the spraying process, so that after the multiple optical module housings 8 are dried, the quality of the finished products remains consistent.
