[0026] Refer to the attached drawings of this utility model specification Figure 1 , a lens assembly pressing device according to an embodiment of the utility model is explained. The lens assembly pressing device includes a frame 1, a controller 2, an air pump 3, a cylinder 4, a pressing head 5 and a placement seat 6, wherein the air pump 3, the cylinder 4 and the placement seat 6 are all arranged on the frame 1, wherein the cylinder 4 is installed at the upper end 11 of the frame 1, and the placement seat 6 is installed at the lower end 12 of the frame 1. The air pump 3 is connected to the air inlet 401 of the cylinder 4, and is used to provide compressed gas with a specific air pressure for the operation of the cylinder 4, such as compressed air, so that the telescopic rod 41 of the cylinder 4 can reciprocate up and down under the air pressure of the gas provided by the air pump 3. The pressing head 5 is installed at the pressing end 411 of the telescopic rod 41 of the cylinder 4, wherein the pressing head 5 can reciprocate up and down with the reciprocating up and down movement of the telescopic rod 41, in other words, the telescopic rod 41 can drive the pressing head 5 to approach or move away from the placement seat 6. The placement seat 6 is used to place and carry the lens or components to be assembled, so that the lens assembly pressing device can perform pressing and assembly, wherein the lens component suitable for being placed on the placement seat 6 is a lens, a pressing ring or an O-ring. The controller 2 is used to control the operation of the air pump 3 to achieve multiple working modes, such as controlling the air pump 3 to inlet air at a single point, controlling the air pump 3 to work at a set number of pressing times, and controlling the air pump 3 to work with a delay, etc.

[0027] like Figure 1 As shown, specifically, the air inlet 401 of the cylinder 4 of the lens assembly pressing device includes an upper air inlet 4011 and a lower air inlet 4012, wherein the air pump 3 is connected to the upper air inlet 4011 of the cylinder 4 through a first air inlet pipe 101, and the air pump 3 is connected to the lower air inlet 4012 of the cylinder 4 through a second air inlet pipe 102. When the controller 2 controls the air pump 3 to supply compressed gas to the first air inlet pipe 101, the compressed gas enters the upper air inlet 4011 of the cylinder 4 through the first air inlet pipe 101, drives the telescopic rod 41 to move downward, and makes the telescopic rod 41 drive (or drive) the pressing head 5 to move downward, and uses the pressing head 5 to press and assemble the lens or components. When the controller 2 controls the air pump 3 to supply compressed gas to the second air inlet pipe 102, the compressed gas enters the lower air inlet 4012 of the cylinder 4 through the second air inlet pipe 102, driving the telescopic rod 41 to move upward, so that the telescopic rod 41 drives (or drives) the pressing head 5 to move upward, thereby separating the pressing head 5 from the lens or components in the placement seat 6.

[0028] Reference Manual Attached Figure 1In particular, the pressing head 5 includes a motor 51, an assembly tool 52 and a pressure sensor 53, wherein the motor 51 is fixedly mounted on the pressing end 411 of the telescopic rod 41, the assembly tool 52 is detachably mounted on the motor 51, and the pressure sensor 53 is mounted between the motor 51 and the assembly tool 52, wherein the motor 51 and the pressure sensor 53 are both electrically connected to the controller 2. When the telescopic rod 41 drives (or drives) the pressing head 5 to move downward, so that the assembly tool 52 contacts the lens or component in the placement seat 6, the pressure sensor 53 feeds back the measured pressure value to the controller 2, and then the controller 2 controls the motor 51 to rotate, and then the motor 51 drives (or drives) the assembly tool 52 to rotate, thereby realizing the pressing assembly. Preferably, the assembly tool 52 is screwed to the motor 51, so as to facilitate the rapid replacement of the assembly tool 52 to meet the assembly of different components such as lenses, pressure rings and O-rings.

[0029] In some embodiments of the present invention, a limiting nut 410 is provided at the limiting end 412 of the telescopic rod 41 of the cylinder 4 for limiting and restraining the telescopic rod 41 during its movement to limit the telescopic stroke of the telescopic rod 41 .

[0030] Those skilled in the art can understand that the controller 2 can control the air pump 3 to realize a variety of working step modes, such as a single-step control mode, a semi-automatic control mode, and a delay control mode. For example, in the single-step control mode, the controller 2 controls the single-point air intake of the air pump 3, and the compressed gas enters the upper air inlet 4011 of the cylinder 4 through the first air intake pipe 101, driving the telescopic rod 41 to move downward, so that the telescopic rod 41 drives the pressing head 5 to move downward, and the telescopic rod 41 drives the motor 51 to move downward, and the motor 51 drives the assembly tool 52 to move downward to press and assemble the lens or component. When the assembly tool 52 contacts the lens or component in the placement seat 6, the pressure sensor 53 feeds back the measured pressure value. To the controller 2, and then the controller 2 controls the motor 51 to rotate, and then the motor 51 drives the assembly tool 52 to rotate, so as to realize the pressing assembly. After the assembly is in place, the controller 2 controls the air pump 3 to inlet air at a single point, and the compressed gas enters the lower air inlet 4012 of the cylinder 4 through the second air inlet pipe 102, driving the telescopic rod 41 to move upward, so that the telescopic rod 41 drives the pressing head 5 to move upward, and then the pressing head 5 is separated from the lens or component in the placement seat 6, and the controller 2 controls and records the number of pressing assemblies. Exemplarily, in the semi-automatic control mode, the number of pressing assemblies can be pre-set by the controller 2, and the controller 2 automatically controls the pressing head 5 to move up and down a set number of times to complete multiple pressing and assembly actions on the lens or component. Exemplarily, in the delay control mode, a delay time can be pre-set by the controller 2, and the controller 2 can automatically control the pressing head 5 to delay the execution of the action upward or downward to complete the delayed pressing assembly of the lens or component. In other words, the controller 2 is configured to automatically control the number of times the pressing head 5 moves up and down to achieve multiple pressing and assembling actions on the lens or components. It can be understood that the lens assembly pressing device of the utility model can flexibly set the pressing times, use the controller 2 to control the air pump 3, and drive the pressing head 5 to move up and down through the cylinder 4 to approach or move away from the placement seat 6, thereby achieving automatic pressing and assembly, improving assembly efficiency, increasing production rhythm, and helping to control product quality.

[0031] Reference Manual Attached Figure 1In some embodiments of the utility model, the lens assembly pressing device further includes a negative pressure converter 7 and a negative pressure tube 8, wherein the gas inlet 701 of the negative pressure converter 7 is connected to the gas outlet 402 of the cylinder 4, and is used to recover the compressed gas output by the cylinder 4 during operation, so that the compressed gas enters the negative pressure converter 7 through the gas inlet 701 of the negative pressure converter 7 and is recycled to generate negative pressure. One end of the negative pressure tube 8 is connected to the negative pressure port 702 of the negative pressure converter 7, and the other end of the negative pressure tube 8 is connected to the placement groove 60 of the placement seat 6, so that the negative pressure suction force generated by the negative pressure converter 7 at the negative pressure port 702 can adsorb the lens or component in the placement groove 60 of the placement seat 6 through the negative pressure tube 8. Those skilled in the art can understand that the compressed gas output by the cylinder 4 during the working process can enter the negative pressure converter 7 through the gas inlet 701 of the negative pressure converter 7. After the compressed gas enters the negative pressure converter 7, the pressure is released and converted into high-speed flowing gas. The high-speed flowing gas quickly flows over the negative pressure port 702 of the negative pressure converter 7, and the pressure difference is used to generate negative pressure suction at the negative pressure port 702 of the negative pressure converter 7, thereby converting the recovered compressed gas into negative pressure.

[0032] like Figure 1As shown, specifically, the gas outlet 402 of the cylinder 4 includes an upper gas outlet 4021 and a lower gas outlet 4022, wherein a first recovery pipe 103 is provided between the gas inlet 701 of the negative pressure converter 7 and the upper gas outlet 4021 of the cylinder 4, and a second recovery pipe 104 is provided between the gas inlet 701 of the negative pressure converter 7 and the lower gas outlet 4022 of the cylinder 4, wherein the first recovery pipe 103 is provided with a first check valve 1031 to allow the compressed gas to flow from the upper gas outlet 4021 of the cylinder 4 to the lower gas outlet 4022. The second recovery pipe 104 is provided with a second one-way valve 1041 to allow the compressed gas to flow from the lower gas outlet 4022 of the cylinder 4 to the gas inlet 701 of the negative pressure converter 7, and to prevent the compressed gas from flowing from the gas inlet 701 of the negative pressure converter 7 to the upper gas outlet 4021 of the cylinder 4. The second recovery pipe 104 is provided with a second one-way valve 1041 to allow the compressed gas to flow from the lower gas outlet 4022 of the cylinder 4 to the gas inlet 701 of the negative pressure converter 7, and to prevent the compressed gas from flowing from the gas inlet 701 of the negative pressure converter 7 to the lower gas outlet 4022 of the cylinder 4. Those skilled in the art can understand that when the telescopic rod 41 of the cylinder 4 moves back and forth up and down, the upper air outlet 4021 and the lower air outlet 4022 of the cylinder 4 will switch back and forth to output compressed gas. When the compressed gas enters the first recovery pipe 103 from the upper air outlet 4021 of the cylinder 4, the first one-way valve 1031 allows the compressed gas to flow in the direction of the gas inlet 701 of the negative pressure converter 7, and the second one-way valve 1041 prevents the compressed gas from flowing from the gas inlet 701 of the negative pressure converter 7 to the lower air outlet 4022 of the cylinder 4, so the compressed gas The compressed gas can only enter the negative pressure converter 7 through the gas inlet 701 of the negative pressure converter 7. Accordingly, when the compressed gas enters the second recovery pipe 104 from the lower gas outlet 4022 of the cylinder 4, the second one-way valve 1041 allows the compressed gas to flow in the direction of the gas inlet 701 of the negative pressure converter 7, and the first one-way valve 1031 prevents the compressed gas from flowing from the gas inlet 701 of the negative pressure converter 7 to the upper gas outlet 4021 of the cylinder 4. Therefore, the compressed gas can only enter the negative pressure converter 7 through the gas inlet 701 of the negative pressure converter 7. Therefore, no matter whether the telescopic rod 41 of the cylinder 4 moves upward or downward, the compressed gas output by the cylinder 4 during the working process is recovered into the negative pressure converter 7, utilized and converted into negative pressure, so that the lens or components in the placement groove 60 of the placement seat 6 can be continuously negatively adsorbed.

[0033] It is worth mentioning that the lens assembly pressing device of the present invention recovers the compressed gas (such as compressed air) output by the cylinder 4 during the working process, and utilizes the recovered compressed gas through the negative pressure converter 7 to convert it into a negative pressure for adsorbing and fixing the lens or components to be assembled. Compared with the traditional non-fixed method, it can prevent the lens or components from moving during the pressing and assembly process. Compared with the traditional clamping and fixing method, it can prevent the lens or components from being damaged by friction or scratching the clamping structure.

[0034] In some embodiments of the present invention, the lens assembly pressing device also includes a silencer 9, wherein the silencer 9 is arranged at the gas outlet 703 of the negative pressure converter 7, wherein the high-speed flowing gas in the negative pressure converter 7 enters the silencer 9 through the gas outlet 703 of the negative pressure converter 7, and the silencer 9 can eliminate the noise emitted when the high-speed flowing gas passes through the gas outlet 703 of the negative pressure converter 7.

[0035] Those skilled in the art should understand that the above description and the embodiments shown in the drawings are only for illustrative explanation of the present invention, rather than for limiting the present invention. All equivalent implementations, modifications and improvements within the spirit of the present invention should be included in the protection scope of the present invention.
