Description

Technical Field

[0001] The utility model belongs to the technical field of lens processing and relates to a glue dispensing device, in particular to a glue dispensing device for a lens. Background Art

[0002] A camera module consists of multiple camera lenses and a housing. The camera lenses are fixed to the housing via adhesive dispensing. The adhesive bonding of the optical lens primarily involves the lens element and the lens mount. This bonding process involves attaching a plastic or glass lens to the lens mount, typically using transparent UV glue (ultraviolet light-curing adhesive). Conventional glue dispensing is typically performed manually. While manual labor can ensure precision, it can lead to fatigue and errors after long hours. Furthermore, manual glue dispensing is slower than mechanical dispensing, impacting the speed of camera assembly. Furthermore, manual labor costs are higher than those of mechanical processing, increasing the cost of the camera.

[0003] A search revealed a Chinese patent document that discloses a multi-position adjustable dispensing device for an optical lens [Application Number: 202122301530.8; Publication Number: CN215878597U]. This multi-position adjustable dispensing device for an optical lens allows the adjustment rod to slide along a perforation in the adjustment seat when the locking member is released, thereby changing the extension of the adjustment rod relative to the adjustment seat. When the pressure cap is released, the adjustment seat can rotate relative to the support rod to change the relative angle of the adjustment rod, thus achieving multiple position adjustments for the dispensing assembly.

[0004] Although the multi-position adjustable optical lens dispensing device disclosed in this patent realizes flexible adjustment of the dispensing position, the dispensing device requires manual disassembly and assembly of the lens before and after dispensing. The glue is not dry after dispensing, and the lens assembly after disassembly needs to be handled carefully to prevent the glue from being contaminated to other places or flowing out, thereby reducing work efficiency and dispensing quality. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a lens dispensing device. The technical problem to be solved by this utility model is: how to achieve rapid unloading of the assembled lens after solidification for subsequent dispensing, thereby improving the dispensing efficiency.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A dispensing device for a lens comprises a workbench, a three-dimensional displacement mechanism is provided on the top of the workbench, a dispensing assembly is provided on the three-dimensional displacement mechanism, a solidification mechanism is provided on the top of the workbench, the solidification mechanism comprises a mounting frame fixed to the top of the workbench, a second electric telescopic rod is fixed to the top of the mounting frame by bolts, a fixing plate is fixed to the top of the second electric telescopic rod, a connecting rod is fixed to the rear bottom of the fixing plate, a slide is fixed to the bottom of the connecting rod, a slide is passed through the center of the slide, a baffle is fixed to the rear end of the slide, a square groove is provided in the center of the bottom of the baffle, the bottom end of the slide is fixed to the mounting frame, an ultraviolet lamp board is fixed to the right bottom of the mounting frame, and a placement mechanism is provided below the ultraviolet lamp board.

[0008] The working principle of the utility model is as follows: the lens structure to be glued is placed in the placement mechanism, the placement mechanism drives the lens structure to move to the bottom of the glue dispensing component, and glue is dispensed under the operation of the three-dimensional displacement mechanism. After the glue is dispensed, the staff promptly places the other part to be spliced on the glued lens through an external mechanical arm or manually. When the lens moves with the cross rotating frame in the placement mechanism, the second electric telescopic rod is extended, the fixed plate moves up with the second electric telescopic rod, the connecting rod moves up with the fixed plate, and the slide slides upward on the slide rod with the connecting rod (a limited block is integrally formed on the top of the slide rod to prevent the slide from continuously moving up and falling out), and the baffle moves with the slide Move it upward to open the internal space of the mounting frame, so that the cross turret can drive the lens after dispensing to move to the bottom of the UV lamp board. Then the second electric telescopic rod retracts, causing the baffle to move downward indirectly with the second electric telescopic rod to separate the lens after dispensing and the lens in dispensing (the baffle is a black opaque plate). At this time, a placement arm of the cross turret is in contact with the square groove (the cross turret is composed of four vertically crossed placement arms). At this time, the UV lamp board is turned on to illuminate the top of the lens after dispensing. After solidification is completed, the placement mechanism drives the lens to the front of the worker, and the lens that is firmly combined after solidification can be directly taken out without the risk of offset at the assembly point.

[0009] Four universal wheels are fixed to the bottom of the workbench by bolts.

[0010] With the above structure, the universal wheels can be rolled on the ground by pushing the workbench, so that the dispensing device can be moved to the desired placement position as a whole, making the device easy to move as a whole.

[0011] The three-dimensional displacement mechanism includes four columns fixed on the left and right sides of the workbench top, the first linear motor is fixed on the top of the two left columns, the slide rail is fixed on the top of the two right columns, the slide rail and the moving end of the first linear motor are both provided with a first slider, the second linear motor is fixed on the top of the two first sliders, the second linear motor is fixed on the moving end of the second linear motor, the first electric telescopic rod is fixed on the front end of the second slider, and the dispensing assembly is arranged at the bottom end of the first electric telescopic rod.

[0012] With the above structure, when the first linear motor is running, the moving end of the first linear motor can drive the first slider on the left to slide on the sliding track of the first linear motor, and the second linear motor moves back and forth with the first slider, and the first slider on the right moves back and forth linearly with the second linear motor on the slide rail, so that the sliding is smoother, and the movement of the dispensing component on the Y axis is realized. When the second linear motor is running, the moving end of the second linear motor can drive the second slider to move left and right, and the first electric telescopic rod and the dispensing component move left and right linearly with the second slider to realize the movement of the dispensing component on the X axis. When the first electric telescopic rod is running, the connecting plate drives the dispensing component to move up and down linearly with the moving end of the first electric telescopic rod to realize the movement of the dispensing component on the Z axis. In summary, three-dimensional movement is realized to adjust the dispensing position.

[0013] The dispensing assembly comprises a back-suction dispensing valve body, a glue bottle is threadedly connected to the back-suction dispensing valve body, and a dispensing head is threadedly connected to the bottom of the back-suction dispensing valve body.

[0014] With the above structure, when the back-suction dispensing valve body is in operation, the UV glue in the glue bottle is dispensed to the lens joints through the dispensing head. The back-suction dispensing valve body can back-suction and cut off the glue at the moment of stopping the glue, thereby improving the dispensing quality.

[0015] The back-suction type dispensing valve body is fixed to the bottom end of the first electric telescopic rod through a connecting plate.

[0016] With the above structure, the connecting plate is respectively connected to the first electric telescopic rod and the back-suction type dispensing valve body by bolts, so that the back-suction type dispensing valve body is detachable and easy to repair and replace.

[0017] The placement mechanism includes a fixing frame fixed at the front of the top of the workbench, a servo motor is fixed to the bottom of the fixing frame by bolts, the output end of the servo motor is key-connected to a cross rotating frame, four internal threaded cylinders are evenly fixed on the top of the cross rotating frame, the inner wall of the internal threaded cylinder is threadedly connected to a threaded plate, and a placement frame is integrally formed on the top of the threaded plate.

[0018] The above structure is adopted, and a placement frame that is compatible with the specifications of the processed lens is selected, and the threaded plate at the bottom of the frame is aligned with the internal threaded barrel and then rotated. The installation of the placement frame is achieved through threaded transmission, so that the specifications of the processed lens are not limited and it is easy to disassemble and replace. The lens to be glued is placed in the placement frame. When the servo motor is running, the cross turret rotates 90° clockwise with the output end of the servo motor, and stops every 90° rotation, so that the lens being processed by the cross turret is in the front, back, left and right directions each time it is paused. The front placement frame is used for workers to disassemble and assemble the processed lens, the left placement frame is in the waiting area, the rear placement frame is used for glue dispensing under the glue dispensing head, and the right placement frame is located under the ultraviolet lamp board to dry the glue just dispensed with ultraviolet light to solidify the UV glue. After the UV glue is solidified, the lens continues to move to the front with the placement frame so that the worker can take out the finished product, so that the disassembly, gluing and light solidification steps are carried out simultaneously, thereby improving work efficiency.

[0019] The top of the placement frame contacts the chassis, a short column is fixed at the bottom of the chassis, a through hole for the short column to pass through is opened at the bottom of the placement frame, and a limiting piece is integrally formed at the bottom of the short column.

[0020] With the above structure, when a lens is placed in the placement frame, the weight of the lens itself presses the chassis into the placement frame. After the UV glue solidifies, move your finger under the limit piece and apply upward force. The short column moves upward in the through hole along with the limit piece, and the chassis moves upward with the short column to push out the combined lens, making it easier to unload.

[0021] Compared with the existing technology, the dispensing device of this lens has the following advantages:

[0022] 1. By setting up a UV light board under the mounting frame to solidify the lens after dispensing glue, the processed lens can be directly taken out when unloading, and the glue can be spliced in time to improve production quality.

[0023] 2. By setting up a placement mechanism, the cross-shaped rotating frame drives the four lens components to move to different processing step areas, so that the steps of disassembling and installing the lens in the frame, assembling after dispensing, and solidifying under light can be carried out simultaneously. After solidification, the assembled lens can be quickly unloaded for subsequent dispensing, thereby improving the dispensing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The first slider 6 on the right moves back and forth linearly with the second linear motor 7 on the slide rail 5, making the sliding smoother, thereby realizing the movement of the dispensing component on the Y-axis. When the second linear motor 7 is running, the moving end of the second linear motor 7 can drive the second slider 8 to move left and right, and the first electric telescopic rod 9 and the dispensing component move left and right linearly with the second slider 8, thereby realizing the movement of the dispensing component on the X-axis. When the first electric telescopic rod 9 is running, the connecting plate 901 drives the dispensing component to move up and down linearly with the moving end of the first electric telescopic rod 9, thereby realizing the movement of the dispensing component on the Z-axis. In summary, three-dimensional movement is realized to adjust the dispensing position.

[0035] The dispensing assembly includes a back-suction dispensing valve body 10, a glue bottle 11 is threadedly connected to the back-suction dispensing valve body 10, and a dispensing head 12 is threadedly connected to the bottom of the back-suction dispensing valve body 10.

In this embodiment, a placement frame 20 that is compatible with the specifications of the processed lens is selected, and the threaded plate 19 at the bottom is aligned with the internal threaded barrel 18 and then rotated. The installation of the placement frame 20 is achieved through thread transmission, so that the specifications of the processed lens are not limited and it is easy to disassemble and replace. The lens to be dispensed is placed in the placement frame 20 When the servo motor 16 is running, the cross turret 17 rotates 90° clockwise along with the output end of the servo motor 16, and stops every 90°, so that the lens being processed by the cross turret 17 is in the front, back, left and right directions each time it is paused. The front placement frame 20 is used for workers to disassemble and assemble the processed lens, the left placement frame 20 is in the waiting area, the rear placement frame 20 is placed under the dispensing head 12 for dispensing glue, and the right placement frame 20 is located under the ultraviolet lamp board 14 to irradiate the glue just dispensed with ultraviolet light to solidify the UV glue. After the UV glue is solidified, the lens continues to move to the front with the placement frame 20 so that the worker can take out the finished product, so that the disassembly, dispensing, and lighting solidification steps are carried out simultaneously, thereby improving work efficiency.

The threaded plate 19 at the bottom is aligned with the internal threaded cylinder 18 and then rotated. The lens to be dispensed is placed in the placement frame 20. When the lens is placed in the placement frame 20, the weight of the lens itself presses the chassis 21 into the placement frame 20. The placement mechanism drives the lens structure to move below the dispensing assembly. When the first linear motor 4 is running, the moving end of the first linear motor 4 can drive the first slider 6 on the left to slide on the sliding track of the first linear motor 4, and the second linear motor 7 moves back and forth with the first slider 6, and the first slider 6 on the right moves with the second linear motor 7.

When the second linear motor 7 is running, the moving end of the second linear motor 7 can drive the second slider 8 to move left and right. The first electric telescopic rod 9 and the dispensing component move left and right with the second slider 8 to realize the movement of the dispensing component on the X axis. When the first electric telescopic rod 9 is running, the connecting plate 901 drives the dispensing component to move up and down with the moving end of the first electric telescopic rod 9 to realize the movement of the dispensing component on the Z axis. When the back-suction dispensing valve body 10 is running, the UV glue in the glue bottle 11 is dispensed to the lens splicing through the dispensing head 12. After the dispensing is completed, the staff will promptly place the other part to be spliced on the lens to be dispensed through an external robotic arm or manually. The servo motor When the cross turret 16 is running, the cross turret 17 rotates 90 degrees clockwise along with the output end of the servo motor 16, and stops every 90 degrees, so that the lens being processed by the cross turret 17 is in the front, back, left and right directions each time it is paused. The front placement frame 20 is used for workers to disassemble and assemble the processed lens, the left placement frame 20 is in the waiting area, the rear placement frame 20 is placed under the dispensing head 12 for dispensing glue, and the right placement frame 20 is located under the ultraviolet lamp board 14 to dry the glue just dispensed with ultraviolet light to solidify the UV glue. Before the cross turret 17 rotates, the second electric telescopic rod 24 is extended, the fixed plate 25 moves up with the second electric telescopic rod 24, the connecting rod 26 moves up with the fixed plate 25, and the slide plate 27 slides upward on the slide bar 28 along with the connecting rod 26 (the top of the slide bar 28 is pressed against the slide bar 28). The baffle 23 moves up with the slide 27 to open the internal space of the mounting frame 13, so that the cross turret 17 can drive the lens after dispensing to move to the bottom of the ultraviolet lamp board 14. Then, the second electric telescopic rod 24 retracts, so that the baffle 23 moves down indirectly with the second electric telescopic rod 24 to separate the lens after dispensing and the lens in dispensing (the baffle 23 is a black opaque plate). At this time, the square groove 2301 contacts a placement arm of the cross turret 17 (the cross turret 17 is composed of four placement arms that cross vertically). At this time, the ultraviolet lamp board 14 is turned on to illuminate the top of the lens after dispensing. After solidification is completed, the placement mechanism drives the lens to the front of the worker, and the finger is moved to the bottom of the limit piece 2201 and force is applied upward.The short column 22 moves upward in the through hole 2001 along with the limiting piece 2201, and the chassis 21 moves upward along with the short column 22 to push out the combined lens. The lens that is firmly combined after solidification can be directly taken out without the risk of displacement at the assembly point.

[0040] In summary, by setting up a solidification mechanism and a placement mechanism, the steps of disassembling and installing the lens in the frame, assembling after gluing, and solidifying under light can be carried out simultaneously. After solidification, the assembled lens can be quickly unloaded for subsequent gluing, thereby improving the gluing efficiency.
