Description

Technical Field

[0001] The invention relates to the technical field of mobile phone production equipment, and in particular to a mobile phone camera cover plate coating mechanism. Background Art

[0002] As consumer electronic products such as digital cameras, mobile phones, PDAs, and even video game consoles become smaller and more sophisticated, these electronic products are usually equipped with optical image capture components, which are required to have higher performance.

[0003] At present, Chinese patent CN201821442116.0 discloses a filter coating device, including a coating machine, wherein at least one pole target is provided in the coating machine, a tray is provided below the pole target, a rotating shaft is provided at the bottom of the tray, the rotating shaft is driven by a stepper motor, a fixture disk concentric with the rotating shaft is provided above the tray, a plurality of placement grooves are provided along the circumference of the upper side of the fixture disk, one of the placement grooves is located directly below the pole target, the coating machine is provided with an air inlet pipe and an exhaust pipe, the exhaust pipe is connected to the dust removal box device and the suction fan in turn through a pipeline, the dust removal device is connected to the vacuum pump through a branch pipe, and a valve is provided on the air inlet pipe; when the suction fan in the above device is sucking air, the horizontal filter screen in the air inlet pipe will adhere to a lot of impurities and cause blockage during long-term use, affecting the subsequent dust removal effect;

[0004] In order to optimize the dust removal effect of the above-mentioned device, another Chinese patent CN202411039920.4 discloses a coating device for a mobile phone camera cover, comprising: a coating machine body, a connecting plate fixedly installed on the side wall of one end of the coating machine body, a box body fixedly installed on the upper end of the connecting plate, and a cover plate installed on the front end of the box body through a hinge. By starting the suction fan, the air inlet pipe starts to intake air, and the air contacts the fan blades after entering. Because the cross-sectional shape of the fan blades is asymmetrical up and down, the wind has different flow rates up and down when passing through the fan blades, forming a pressure difference between the upper and lower sides of the fan blades. The pressure difference generates lift, causing the fan blades to rotate. When the fan blades rotate, they rotate synchronously with the rollers. When the rollers rotate to the lower end of the filter plate, they hit and lift the filter plate, so the filter plate vibrates back and forth, and while vibrating back and forth, the impurities and dust remaining on the filter plate after being filtered by the filter plate are shaken off to the bottom end of the box, and the dust can be cleaned up by opening the cover plate;

[0005] The above technical solution only cleans the residual dust by vibrating the filter plate back and forth. This cleaning method may still leave some dust after the vibration ends, and cannot ensure that the filter plate is completely cleaned. In addition, the cleaned impurities and dust remain at the bottom of the box, and the machine needs to be stopped for cleaning, which has many limitations in use. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 3 , a coating mechanism for a mobile phone camera cover shown in the figure includes a coating machine body 1 and a box body 101. The side of the box body 101 close to the coating machine body 1 is fixedly connected to the coating machine body 1 through an air outlet pipe, and the other side of the box body 101 is fixedly connected with an air inlet pipe 102. A suction fan is installed at the other end of the coating machine body 1. Before the suction fan works, the coating machine body 1 will work first, and the wind will enter the box body 101 from the air inlet pipe 102. After filtering the incoming wind, it will enter the coating machine body 1 through the air outlet pipe to clean the dust and impurities in the coating machine body 1;

[0031] The utility model also comprises: a first filter screen 2 and a second filter screen 3 which are slidably connected to the inside of the box body 101; a replacement unit 4 for exchanging the first filter screen 2 and the second filter screen 3 is installed on the outside of the box body 101; the first filter screen 2 and the second filter screen 3 can be operated to enter and exit one by one through the replacement unit 4, so that the filter screens can be quickly pulled out and manually cleaned externally; at the same time, the cleaned filter screens are automatically replaced into the box body 101, so that the two filter screens can work alternately, and there is no need to stop the machine to disassemble and wash the filter screens, thereby improving the cleaning efficiency of the filter screens;

[0032] A No. 3 filter screen 5 is fixed at the end of the air inlet pipe 102, and a No. 1 cleaning unit 6 is provided between the replacement unit 4 and the No. 3 filter screen 5, which can produce a linkage effect when the replacement unit 4 is operated, thereby automatically cleaning the No. 3 filter screen 5 of the air inlet pipe 102;

[0033] The No. 2 cleaning unit 7 is installed on the top of the coating machine body 1, and one end of the replacement unit 4 is transmission connected to the No. 2 cleaning unit 7, which can produce a linkage effect when the replacement unit 4 is operated, thereby automatically cleaning the top of the coating machine body 1, which can reduce the probability of the coating machine being exposed to the outside for a long time and easily falling into dust, causing equipment aging, effectively clean and protect the coating machine, and also save the trouble of manual cleaning and wiping.

[0034] For further information, see Figure 3 and Figure 4 The replacement unit 4 includes a transmission rod 401, a No. 1 gear 402, a No. 2 gear 403, a No. 1 rack 404 and a No. 2 rack 405. The No. 1 gear 402 and the No. 2 gear 403 are respectively fixed at both ends of the transmission rod 401. The upper and lower sides of the No. 1 gear 402 and the No. 2 gear 403 are meshed and connected with the No. 1 rack 404 and the No. 2 rack 405. The top of the No. 1 rack 404 and the bottom of the No. 2 rack 405 are fixed with a connecting piece 406. The No. 1 rack 404 and the No. 2 rack 405 are respectively connected to the No. 1 filter 2 and the No. 2 filter 2 through the connecting piece 406. The filter screen 3 is detachably connected, and four evenly distributed diamond columns 407 are fixed on the outer side of the box body 101, and a connecting frame 408 is fixed at one end of the four diamond columns 407. The transmission rod 401 is rotatably connected to the connecting frame 408 through a bearing seat, and a driving member 409 is provided between the transmission rod 401 and the connecting frame 408. A first rotating shaft 4010 and a second rotating shaft 4011 are respectively fixed at both ends of the transmission rod 401, and the first rotating shaft 4010 is transmission-connected to the input end of the No. 1 cleaning unit 6, and the No. 2 rotating shaft 4011 is transmission-connected to the input end of the No. 2 cleaning unit 7.

[0035] Specifically, the personnel drives the transmission rod 401 to rotate through the driving member 409, so that the No. 1 gear 402 and the No. 2 gear 403 at both ends of the transmission rod 401 rotate together, thereby driving the No. 1 gear 402 and the No. 1 rack 404 on the top of the No. 2 gear 403 to move away from the box body 101, so that the No. 1 filter 2 is pulled out from the inside of the box body 101, and the No. 2 rack 405 at the bottom of the No. 1 gear 402 and the No. 2 gear 403 moves toward the direction close to the box body 101, and the No. 2 filter 3 is sent into the inside of the box body 101. At this time, the personnel can quickly disassemble the No. 1 filter 2 through the connecting member 406. Then take out the No. 1 filter 2 for cleaning. After cleaning, fix it to the No. 1 rack 404 through the connecting piece 406. At this time, the No. 2 filter 3 is inside the box 101. The filtering work can continue inside the box 101 without stopping, thereby ensuring the efficiency of cleaning the coating machine. Until it is used for a period of time, the driving piece 409 is reversed. At this time, the No. 2 filter 3 will be pulled out according to the above process, and the No. 1 filter 2 will be sent into the box 101. Then the No. 2 filter 3 will be manually cleaned, thereby realizing the alternating operation of the two filters. There is no need to stop the filter for disassembly and cleaning, thereby improving the cleaning efficiency of the filter.

[0036] For further information, see Figure 4 The driving member 409 includes a worm 4091, a worm wheel 4092 and a crank 4093. The worm 4091 is rotatably connected to the connecting frame 408 through a bearing seat. The worm wheel 4092 is fixedly sleeved on the middle part of the transmission rod 401. The worm 4091 and the worm wheel 4092 are meshingly connected. A fixed shaft 4094 is fixed to the top of the worm 4091. The crank 4093 is fixedly connected to the worm 4091 through the fixed shaft 4094.

[0037] Specifically, the operator turns the crank 4093, the crank 4093 drives the fixed shaft 4094 to rotate, the fixed shaft 4094 drives the worm 4091 to rotate, the worm 4091 drives the worm wheel 4092 to rotate, the worm wheel 4092 drives the transmission rod 401 to rotate, and the transmission rod 401 drives the first gear 402 and the second gear 403 to rotate together, thereby realizing the alternating movement of the two racks.

[0038] For further information, see Figure 5 The connecting piece 406 includes an L-shaped plate 4061, a threaded column 4062 and a fixing nut 4063. The L-shaped plate 4061 is slidably connected with the diamond column 407. One end of the threaded column 4062 located on the upper side of the No. 1 rack 404 is fixed to the No. 1 filter 2, and one end of the threaded column 4062 located on the lower side of the No. 2 rack 405 is fixed to the No. 2 filter 3. The L-shaped plate 4061 is inserted into the outer side of the threaded column 4062 and is threadedly connected to the threaded column 4062 through two fixing nuts 4063.

[0039] Specifically, when one of the filters is pulled out from the box body 101, one of the fixing nuts 4063 is removed from the threaded column 4062 by rotating the fixing nut 4063, thereby loosening the fixing effect of the L-shaped plate 4061 and the threaded column 4062, and then the filter is pulled out from the L-shaped plate 4061 to complete the disassembly work, thereby facilitating personnel to quickly remove the filter for cleaning.

[0040] For further information, see Fig. 9 A connecting column 4051 is fixed to one side of the No. 2 rack 405, an inclined rod 4052 is fixed to one end of the connecting column 4051, and a No. 3 brush 4053 is fixed to one end of the inclined rod 4052 away from the connecting column 4051, and the bottom of the No. 3 brush 4053 contacts the top of the box 101.

[0041] Specifically, when the No. 2 rack 405 moves toward the box body 101, the No. 3 brush 4053 will be pushed to move together through the connecting column 4051 and the inclined rod 4052. Because dust is easy to accumulate on the top of the box body 101, when replacing the No. 1 filter 2 and the No. 2 filter 3, the No. 3 filter 5 can be used to push on the top of the box body 101. The No. 3 filter 5 can clean the dust accumulated on the top of the box body 101 to ensure that the box body 101 is sufficiently clean.

[0042] Example 2: Please refer to Figure 6 This embodiment further explains the first embodiment, and the difference lies in that the filter cleaning method on the air inlet pipe 102 is optimized.

[0043] Specifically, the first cleaning unit 6 includes a first pulley 601, a first belt 602, a second pulley 603, a third shaft 604 and a third gear 605, a gear ring 606 and a first brush 607. The first pulley 601 is fixedly sleeved with the first shaft 4010, the second pulley 603 is connected to the first pulley 601 through the first belt 602, and the second pulley 603 and the third gear 605 are fixedly sleeved on the third shaft 4010. On the shaft 604, one end of the third rotating shaft 604 is rotatably connected to the outer wall of the box body 101, the inner side of the ring gear 606 is rotatably connected to a slewing bearing 608, and the slewing bearing 608 is fixedly sleeved on the outer side of the air inlet pipe 102. The third gear 605 is meshingly connected with the ring gear 606, and the brush surface of the number one brush 607 contacts the surface of the number three filter 5. The top of the number one brush 607 is fixedly connected to the front side of the ring gear 606 through a fixing rod.

[0044] Specifically, when the transmission rod 401 rotates, it will drive the No. 1 shaft 4010 to rotate, the No. 1 shaft 4010 will drive the No. 1 pulley 601 to rotate, the No. 1 pulley 601 will drive the No. 2 pulley 603 to rotate through the No. 1 belt 602, the No. 2 pulley 603 and the No. 3 shaft 604 will rotate, the No. 3 shaft 604 will drive the No. 3 gear 605 to rotate, the No. 3 gear 605 will drive the ring gear 606 to rotate, the ring gear 606 will drive the No. 1 brush 607 to sweep the surface of the No. 3 filter 5, thereby automatically cleaning the dust on its surface. Compared with the existing method of needing to unscrew the filter for cleaning, the workload will be greatly reduced and the cleaning efficiency of the filter at the air inlet pipe 102 will be improved.

[0045] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further explains other embodiments, and the difference lies in the optimization of the coating machine body 1.

[0046] Specifically, the second cleaning unit 7 includes a third pulley 701, a second belt 702, a fourth pulley 703, a fourth rotating shaft 704, a moving member 705 and a second brush 706. The third pulley 701 is fixedly connected with the second rotating shaft 4011, the third pulley 701 is connected to the fourth pulley 703 through the second belt 702, the fourth pulley 703 is fixedly connected with the fourth rotating shaft 704, the brush surface of the second brush 706 is in contact with the top of the coating machine body 1, and the output end of the moving member 705 is fixed to the second brush 706; the moving member 705 includes a trapezoidal thread screw 7051, a moving block 70 52. Sliding column 7053 and slot plate 7054, trapezoidal thread screw 7051 is threadedly sleeved with moving block 7052, both ends of trapezoidal thread screw 7051 are fixed with No. 4 rotating shaft 704, slot plate 7054 is fixed to the outer side of coating machine body 1, sliding column 7053 is slidably sleeved in slot plate 7054, the bottom of moving block 7052 is fixed with sliding column 7053, one end of No. 2 brush 706 is fixed with moving block 7052 through connecting plate, both ends of slot plate 7054 are fixed with supporting plates 7055, and No. 4 rotating shaft 704 is rotatably connected with the top of supporting plate 7055 through bearing seat.

[0047] Specifically, when the transmission rod 401 rotates, it will drive the second shaft 4011 to rotate, the second shaft 4011 drives the third pulley 701 to rotate, the third pulley 701 drives the fourth pulley 703 to rotate through the second belt 702, the fourth pulley 703 drives the fourth shaft 704 to rotate, and the fourth shaft 704 drives the trapezoidal thread screw 7051 to rotate. Since the trapezoidal thread screw 7051 has a larger pitch than the ordinary thread, this thread has a higher transmission efficiency, and the transmission ratio between the second gear 403 and the rack is one, the coating machine body 1 is The length of the part is much larger than the length of the rack, so the use of the trapezoidal thread screw 7051 can change the transmission ratio between the transmission rod 401 and the trapezoidal thread screw 7051, making the structural layout more reasonable, so that when the moving block 7052 moves from one side to the other, it just drives the second brush 706 to clean the largest area, thereby achieving the effect of automatically cleaning the top of the coating machine body 1, which can reduce the probability of the coating machine being exposed to the outside for a long time and easily falling into dust, causing equipment aging, effectively cleaning and protecting the coating machine, and also saving the trouble of manual cleaning and wiping.

[0048] It should be noted that the outer side of the coating machine body 1 is rotatably connected to the fifth rotating shaft 707 through a bearing, and the outer side of the fifth rotating shaft 707 is fixedly sleeved with a tensioning pulley 708. The tensioning pulley 708 and the No. 2 belt 702 are frictionally connected. Because the No. 2 belt 702 is in a vertical distribution, the gravity of the No. 2 belt 702 will have a component force downward along the belt. If the belt is not tensioned, this component force will easily cause the belt to slip on the pulley. Therefore, in order to optimize the transmission effect, the designed tensioning pulley 708 can ensure that the No. 2 belt 702 fits tightly between the pulleys, thereby minimizing the energy loss during power transmission.
