Description

Technical Field

[0001] The present invention relates to the technical field of lens assembly equipment, and in particular to a lens dispensing equipment. Background Art

[0002] When assembling cameras on mobile phones and tablets, the clamping ring and lens barrel must be assembled and glued together to secure them securely. Each step in lens assembly is extremely rigorous, and any incorrect operation can lead to quality issues with the lens installation.

[0003] Now, dispensing operations are performed through various dispensing equipment. For example, the Chinese utility model patent with publication number CN222778326U discloses a high-precision dispensing machine, including a fuselage, a first linear module is provided on the top of the fuselage, both ends of the first linear module are fixedly connected to columns, and the columns are fixedly connected to the fuselage, the output end of the first linear module is fixedly connected to the second linear module, the output end of the second linear module is fixedly connected to the mounting seat, a CCD camera is fixedly connected to the mounting seat, a lens is installed on the CCD camera, a coaxial light source is provided at the bottom of the lens, and a laser displacement sensor is provided on one side of the coaxial light source; the utility model adopts machine vision technology and uses a CCD camera to realize the positioning of the dispensing position, and at the same time uses a laser displacement sensor to detect the height difference of the product dispensing surface, thereby providing data support for eliminating the height difference, and uses a photoelectric sensor to detect the needle position, thereby assisting in correcting the needle. For example, in the dispensing equipment of this patent, when performing a dispensing operation, there will often be glue residue after the dispensing needle completes a dispensing operation. If the residual glue on the dispensing needle is not cleaned in time, the residual glue will solidify over time and affect the dispensing quality, or even clog the dispensing needle. The assembly of the pressure ring and the lens barrel has strict requirements on the dispensing quality, and the dispensing needle needs to be cleaned in time after the dispensing is completed. The current method for cleaning the residual glue on the dispensing needle is generally to set a wiping cloth or sponge on the clamping mechanism and use contact wiping on the dispensing needle. However, this cleaning method will cause the glue on the wiping cloth to solidify, which will affect the wiping quality. The solidified glue is harder and will cause damage to the dispensing needle. On the other hand, this contact-type structure for cleaning residual glue can only clean the glue on the surface of the dispensing needle, and the glue on the inside of the glue outlet of the dispensing needle cannot be cleaned in time, and the cleaning effect is limited.

DETAILED DESCRIPTION

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0052] In this disclosure, terms such as "first," "second," "upper," and "lower" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features designated as "first," "second," "upper," and "lower" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions of various embodiments may be combined, but this must be achievable by persons of ordinary skill in the art. If the technical solutions of various embodiments can be combined, they are within the scope of protection claimed by this disclosure.

[0053] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0054] like Figures 1 to 3As shown, a lens dispensing device includes: a fixing device 300, a dispensing device 200 and a glue cleaning device 100. The fixing device 300 includes a clamp for clamping the lens, and the clamp can rotate about the Z axis. The dispensing device 200 can at least move relative to the fixing device 300 in the X-axis direction and the Z-axis direction. The dispensing device 200 includes a dispensing mechanism 210 and an image acquisition mechanism 220. The dispensing mechanism 210 includes a dispensing needle 2111, and the image acquisition mechanism 220 collects image information of the dispensing position of the lens on the fixing device 300. The dispensing device 200 can at least move relative to the glue cleaning device 100 in the X-axis direction and the Z-axis direction. The glue cleaning device 100 includes: a glue cleaning cylinder 110, an air inlet 1131 and an air exhaust port 1121. The glue cleaning cartridge 110 has a hollow chamber 114 with a socket 11411 at its top. The dispensing needle 2111 is inserted into the hollow chamber 114 through the socket 11411. An air inlet 1131 is provided on the sidewall of the cartridge 110 and is connected to a gas storage container. An air extraction port 1121 is provided at the other end of the hollow chamber 114, opposite the socket 11411, and is connected to an air extraction device.

[0055] The lens after the pressure ring operation is clamped by a fixture. In this embodiment, the fixing device 300 includes a fixture seat and a fixture. The fixture is preferably a three-claw chuck. The fixture is driven by a motor and a transmission mechanism to drive the jaws to clamp and release the lens, and at the same time drive the fixture to rotate around the Z axis. During the dispensing operation, the dispensing needle 2111 is caused to perform a dispensing operation on different parts of the lens by rotating the fixture. Before the dispensing operation, the lens image is first collected by the image acquisition mechanism 220 to confirm the dispensing position and compare it with its preset dispensing position. Therefore, according to the angle difference of the dispensing position, the motor drives the three-claw chuck to rotate, driving the lens barrel to rotate to the preset dispensing angle. The dispensing needle 2111 moves to the top of the fixing device 300 according to the determined dispensing angle, and then descends to the dispensing position to start dispensing. At the same time, the motor drives the three-claw chuck to drive the lens barrel to rotate together, completing the dispensing at the connection between the lens barrel and the pressure ring.

[0056] After the glue dispensing is completed, the glue dispensing needle 2111 is moved to the glue cleaning device 100 to perform a glue cleaning operation on the glue remaining on the glue dispensing needle 2111. The glue dispensing needle 2111 is inserted into the hollow chamber 114, and gas is input into the hollow chamber 114 through the air inlet 1131 to remove the glue remaining on the outside of the glue dispensing needle 2111. At the same time, the input gas forms a negative pressure at the glue outlet of the glue dispensing needle 2111, and the residual glue at the glue outlet can also be quickly removed under the action of the negative pressure. The glue dispensing needle 2111 is connected to an external vacuum device through the air extraction port 1121, and the glue is extracted by vacuuming, thereby improving the glue removal efficiency of the glue dispensing needle 2111 and improving the glue removal effect.

[0057] The lens dispensing device with the above-mentioned structure of this embodiment avoids damage to the dispensing needle 2111 caused by using a wiping cloth, and the glue on the outside and inside of the dispensing needle 2111 is cleaned in time, thereby improving the cleaning effect.

[0058] Further, such as Figure 4 and Figure 5 As shown, an air inlet channel 113 is provided inside the adhesive cleaning cylinder 110. The air inlet channel 113 is connected to the air storage container through the air inlet 1131. The air inlet channel 113 is connected to the hollow chamber 114 through the air blowing port 1135. The area of ​​the air blowing port 1135 is smaller than that of the air inlet 1131. The adhesive dispensing needle 2111 is inserted under the air blowing port 1135 through the socket 11411.

[0059] When performing the glue cleaning operation, the glue dispensing needle 2111 is inserted into the hollow chamber 114 from the socket 11411, and the end of the glue dispensing needle 2111 is inserted below the air port 1135. Gas is input into the hollow chamber 114 through the gas storage container, and the glue remaining in the glue dispensing needle 2111 can be blown off. Preferably, the glue dispensing needle 2111 is inserted below the air port 1135 so that the air port 1135 is located in the upper half of the glue dispensing needle 2111. At the same time, the gas generates negative pressure at the end of the glue dispensing needle 2111, which can suck out the glue remaining inside the glue dispensing needle 2111. The gas input into the hollow chamber 114 needs to have a certain pressure. Therefore, in this embodiment, the area of ​​the air port 1135 is set to be smaller than the area of ​​the air inlet 1131 to increase the flow rate of the gas blown out. An air pump may also be provided between the gas storage container and the gas inlet 1131 to adjust the flow rate of the gas. The specific setting may be made using existing technology according to actual conditions and will not be described in detail here.

[0060] Furthermore, the air inlet channel 113 includes an air inlet portion 1132, an annular portion 1133, and an air blowing portion 1134. The air inlet 1131 is provided on the air inlet portion 1132, and the air blowing portion 1135 is an annular opening provided on the air blowing portion 1134. The annular portion 1133 and the air blowing portion 1135 are both coaxially disposed with the hollow chamber 114. The air blowing portion 1134 is disposed within the sidewall of the rubber cleaning cylinder 110 and is an annular airflow chamber surrounding the hollow chamber 114.

[0061] The gas in the gas storage container is input into the hollow chamber 114 through the air inlet 1131 arranged on the side wall of the glue cleaning cylinder 110. The gas surrounds the hollow chamber 114 through the annular portion 1133 in the middle, and the gas is blown out within a 360° range around the dispensing needle 2111 through the annular blowing port 1135 to ensure that all glue on the dispensing needle 2111 can be blown off by the gas.

[0062] Furthermore, the cleaning cylinder 110 includes a cover plate 111 and a cylinder body 112. The socket 11411 is provided on the upper surface of the cover plate 111. The air extraction port 1121 is provided at the other end of the cylinder body 112 relative to the cover plate 111. The hollow chamber 114 passes through the cover plate 111 and the cylinder body 112. The hollow chamber 114 includes a cover plate chamber provided inside the cover plate 111 and a cylinder body chamber provided inside the cylinder body 112.

[0063] The cylinder body 112 is connected to an external air extraction device via an air extraction pipe 115. The rubber cleaning cylinder 110 is divided into a cover plate 111 and a cylinder body 112, which is convenient for cleaning and daily maintenance of the rubber cleaning cylinder 110.

[0064] Furthermore, the cover plate 111 includes an upper cover 1111 and a lower cover 1112, and the upper cover 1111 and the lower cover 1112 are snap-fitted together. The cover plate chamber includes an upper cover chamber 1141 and a lower cover chamber 1142, and the upper cover chamber 1141 and the lower cover chamber 1142 are both conical, and the minimum diameter ends of the upper cover chamber 1141 and the lower cover chamber 1142 are arranged relative to each other.

[0065] The air flow channel is arranged on the cover plate 111. In order to facilitate the processing of the annular portion 1133 and the annular blowing port 1135, the cover plate 111 is divided into an upper cover 1111 and a lower cover 1112, and the upper cover chamber 1141 and the lower cover chamber 1142 are arranged to be conical, so that the outer diameter of the annular blowing port 1135 can be smaller than the outer diameter of the annular portion 1133, thereby realizing a gradual change of the air flow area from large to small, gradually accelerating the air flow speed, and increasing the pressure of the gas blown out of the blowing port 1135.

[0066] Furthermore, the air inlet 1131 is arranged on the outer wall of the lower cover 1112, the annular portion 1133 is arranged on the surface of the lower cover 1112 relative to the upper cover 1111, and the air outlet 1135 is arranged at the opposite ends of the upper cover chamber 1141 and the lower cover chamber 1142.

[0067] As described above, in order to facilitate processing, the air flow channel is provided on the upper surface of the lower cover 1112 .

[0068] Furthermore, the upper cover 1111 is provided with a conical raised portion, and the upper cover chamber 1141 is disposed within the raised portion. A conical hole is provided within the lower cover 1112, extending from the lower cover chamber 1142 to the surface of the lower cover 1112 opposite the upper cover 1111, and the conical hole engages with the raised portion. The annular portion 1133 surrounds the outside of the raised portion, and the air blowing portion 1134 is disposed on the inner sidewall of the conical hole.

[0069] The conical protrusion and the conical hole are arranged so that the blowing portion 1134 is tapered, and the diameter gradually decreases from large to small. The blowing portion 1134 is arranged on the inner side wall of the conical hole portion for ease of processing.

[0070] Further, such as Figure 2 and Figure 3 As shown, a sponge 120 is provided in the chamber of the barrel portion, and the airflow flows through the sponge 120 to the air extraction port 1121, and the residual glue blown off from the needle is collected by the sponge 120. The sponge 120 is inserted into the chamber of the barrel 112 from the outside of the barrel 112 and can be pulled out of the barrel 112.

[0071] Preferably, an insertion port is provided on the side wall of the cylinder 112, and a tray is provided in the insertion port, and the sponge 120 is placed on the tray. During the glue cleaning operation, the tray carrying the sponge 120 is inserted into the tray so that the sponge 120 covers the cylinder cavity. A through hole is provided at the bottom of the tray. The sponge 120 has a loose texture. Under the action of air extraction, air flows from the cover cavity into the cylinder cavity, passes through the sponge 120, and is extracted from the air extraction port 1121.

[0072] Furthermore, the glue cleaning device 100 also includes a vertical plate 140, to which the glue cleaning cylinder 110 is fixedly connected via an adapter plate 130. The adapter plate 130 is an L-shaped, bent plate, comprising a flat plate and a vertical plate. The vertical plate is provided with an arc-shaped hole, and the vertical plate 140 is provided with multiple through-holes, the arrangement of which matches the shape of the arc-shaped holes. The adapter plate 130 is secured by bolts passing through the arc-shaped holes and the through-holes in the vertical plate 140. The arc-shaped holes allow the fixing angle of the adapter plate 130 to be adjusted, thereby aligning the inclination of the glue cleaning cylinder 110 with the inclination of the glue dispensing needle 2111.

[0073] Further, such as Figure 6 and Figure 7As shown, the dispensing mechanism 210 and the image acquisition mechanism 220 are both fixed to a fixed plate 230 that can move along the X-axis. The dispensing mechanism 210 includes a dispensing assembly 211 and a Z-axis transmission mechanism 212. The dispensing assembly 211 includes a dispensing needle 2111, a side plate 2114, and a first camera 2112. The dispensing needle 2111 is fixed to the side plate 2114 and moves along the Y-axis relative to the fixed plate 230. The side plate 2114 is also provided with a first camera 2112 for capturing images of the dispensing needle 2111. The side plate 2114 is provided with an arcuate slot 21141, which is connected to the Z-axis transmission mechanism 212 via screws passing through the arcuate slot 21141. The image acquisition mechanism 220 includes a second camera 221 and a light source 222.

Specifically, the side plate 2114 is movably fixed to the Z-axis transmission mechanism 212, and the glue dispensing needle 2111 and the first camera 2112 are fixed on the side plate 2114. When performing the glue dispensing operation, the glue dispensing needle 2111 is adjusted to the glue dispensing position of the lens through the Z-axis transmission mechanism. The inclination angle of the glue dispensing needle 2111 can be adjusted by the arc groove 21141. A Y-axis transmission mechanism 2113 is fixed to the side plate 2114, and the glue dispensing needle 2111 is fixed to the side plate 2114 through the Y-axis transmission mechanism 2113. The glue dispensing needle 2111 moves along the Z axis through the Z-axis transmission mechanism and moves along the Y axis through the Y-axis transmission mechanism 2113. The first camera 2112 captures images of the dispensing operation of the dispensing needle 2111, capturing the dispensing action and the glue removal effect of the dispensing needle 2111, allowing staff to monitor the dispensing and glue removal effects in real time. The second camera 221 captures images of the fixture 300, facilitating the positioning of the dispensing needle 2111. The light source 222 provides fill light.

[0075] Further, such as Figure 1 As shown, the lens dispensing device further includes a frame 400, including a base plate 430, an X-axis transmission mechanism 410, and a manipulator mechanism 420. The fixing device 300 and the cleaning device 100 are fixed to the base plate 430. The X-axis transmission mechanism 410 is fixed to the base plate 430, and the dispensing device 200 is movably fixed to the X-axis transmission mechanism 410 via the fixing plate 230. The manipulator mechanism 420 is fixed to the X-axis transmission mechanism 410 so as to be movably fixed along the X-axis direction.

[0076] The dispensing device 200 and the manipulator mechanism 420 can be driven to move along the X axis by the X-axis transmission mechanism 410. After the lens completes the pressing operation, the manipulator picks up the lens and places it on the fixing device 300. The vertical plate 140 of the clearing device 100 is fixed on the bottom plate 430.
