Description

Technical Field

[0001] This utility model relates to the technical field of lens processing, specifically to a glue application mechanism and glue dispensing device. Background Technology

[0002] A laser sensor typically includes a laser emitter, a transmitting lens, a receiving lens, a photosensitive chip, and an information processing system. The transmitting lens is aligned with the laser emitter to adjust the optical performance of the emitted laser through the receiving lens. The receiving lens is aligned with the photosensitive chip to receive and optically process the laser pulse beam emitted from the target object, which is then radiated onto the photosensitive chip. The electrical signal obtained by the photosensitive chip is then sent to the information processing system for post-processing of the collected optical information, displaying it as the required feedback.

[0003] A lens module, consisting of a receiving lens and a transmitting lens, requires adhesive dispensing during its manufacturing process. Currently, this is typically achieved using a dispensing machine. Existing dispensing machines generally include a control pump and a syringe. The syringe has a dispensing head at its end, and the control pump controls the adhesive in the syringe to be sprayed out from the dispensing head to complete the dispensing operation, thus finishing the lens manufacturing process.

[0004] However, existing dispensing machines leave adhesive residue on the needle tip after dispensing, which easily falls off and contaminates the dispensing machine's worktable. Therefore, there is a lack of a dedicated adhesive wiping mechanism to remove the residual adhesive. Utility Model Content

[0005] The purpose of this invention is to provide a glue-applying mechanism and a glue-dispensing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a glue-wiping mechanism, comprising a support base, glue-wiping claws, a drive assembly, and a glue-collecting cup. Two glue-wiping claws are provided, each including a connecting rod and a wiping head. The connecting rod is slidably connected to the support base in the horizontal direction. The two wiping heads are arranged opposite each other and can abut against each other. The drive assembly is located on the support base and drives the two connecting rods to move closer or further apart, thereby achieving the abutment or separation of the two wiping heads. The glue-collecting cup is located on the support base and below the wiping heads, collecting the dripping glue.

[0007] Furthermore, the support base includes a first base body and a second base body, the second base body being slidably connected to the first base body, and the adhesive wiping claw, the driving assembly, and the adhesive receiving cup are all disposed on the second base body.

[0008] Furthermore, the connecting rod is L-shaped, with one end connected to the output end of the drive assembly and the other end connected to the wiping head. The second base is also provided with a support plate, on which the adhesive cup is fixed.

[0009] Furthermore, the adhesive cup is detachably connected to the support plate.

[0010] Furthermore, the wiping head is equipped with an absorbent sponge.

[0011] Furthermore, this application also provides a dispensing device, including the adhesive wiping mechanism described above.

[0012] Furthermore, the dispensing device also includes a dispensing mechanism and an adjusting mechanism. The dispensing mechanism includes a cylinder, a fixed base, and a dispensing needle. The cylinder is disposed on the fixed base and rotatably connected to the fixed base, and the dispensing needle is provided at the end of the cylinder. The adjusting mechanism is disposed on the fixed base, and the adjusting mechanism drives the cylinder to rotate to realize the circumferential movement of the dispensing needle.

[0013] Furthermore, the dispensing device also includes a temperature control component, which includes a heating element and a temperature controller. The heating element is disposed on the cylinder, and the temperature controller is electrically connected to the heating element and disposed on the fixed base.

[0014] Furthermore, the dispensing device also includes a positioning component, which is disposed on the fixed base and located on one side of the cylinder. The positioning component includes a CCD camera, which takes pictures to monitor the position of the dispensing needle.

[0015] Furthermore, the dispensing device also includes a movable slide rail, on which a drive motor is mounted, and the drive motor drives the cylinder to slide and connect to the movable slide rail.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. After the dispensing operation is completed, the dispensing needle moves to the middle position between the two wiping heads. The drive assembly then moves the two wiping heads closer together and abuts against the dispensing needle, wiping away any residual adhesive. A receiving cup is located below the wiping heads to collect any adhesive that drips during the wiping process, preventing it from falling onto the worktable. The adhesive wiping mechanism in this application can promptly remove adhesive residue from the dispensing needle, avoiding the problem of adhesive dripping and contaminating the worktable.

[0018] 2. The connecting rod is L-shaped. One end of the connecting rod is connected to the output end of the drive component, and the other end is connected to the wiping head. The second base is also equipped with a support plate, on which a glue cup is fixed. The L-shaped connecting rod leaves space for the glue cup to be installed, making it easy to install the glue cup directly below the wiping head.

[0019] 3. The glue collecting cup is detachably connected to the support plate. When a large amount of glue is collected, the glue collecting cup can be removed to remove the excess glue. After cleaning, the glue collecting cup can be reinstalled back onto the support plate. Attached Figure Description

[0029] Example 1

[0030] An adhesive wiping mechanism 10 provided in this embodiment of the present invention includes a support base 11, adhesive wiping claws 12, a drive assembly 13, and an adhesive collection cup 14. There are two adhesive wiping claws 12, each of which includes a connecting rod 121 and a wiping head 122. The connecting rod 121 is slidably connected to the support base 11 in the horizontal direction, and the two wiping heads 122 are arranged opposite to each other and can abut against each other. The drive assembly 13 is disposed on the support base 11, and the drive assembly 13 drives the two connecting rods 121 to move closer or further away from each other, so as to realize the abutment or separation of the two wiping heads 122. The adhesive collection cup 14 is disposed on the support base 11 and located below the wiping head 122 to collect the dripping adhesive.

[0031] After the dispensing operation is completed, the dispensing needle 23 moves to the middle position between the two wiping heads 122. Driven by the drive assembly 13, the two wiping heads 122 approach each other and abut against the dispensing needle 23, wiping away any remaining adhesive on the needle 23. A receiving cup 14 is provided below the wiping heads 122 to collect any adhesive that drips from the needle 23 during wiping, preventing it from falling onto the worktable. The adhesive wiping mechanism 10 in this application can promptly remove the adhesive remaining on the dispensing needle 23, avoiding the problem of adhesive dripping and contaminating the worktable.

[0032] Specifically, the support base 11 includes a first base 111 and a second base 112. The second base 112 is slidably connected to the first base 111. The adhesive wiping gripper 12, the drive assembly 13, and the adhesive receiving cup 14 are all disposed on the second base 112. In this embodiment, the connecting rod 121 is L-shaped. One end of the connecting rod 121 is connected to the output end of the drive assembly 13, and the other end is connected to the wiping head 122. The second base 112 is also provided with a support plate 113, on which the adhesive receiving cup 14 is fixed. The L-shaped connecting rod 121 can leave installation space for the adhesive receiving cup 14, making it convenient for the adhesive receiving cup 14 to be installed directly below the wiping head 122. The adhesive receiving cup 14 is detachably connected to the support plate 113. When a large amount of adhesive is collected, the adhesive receiving cup 14 can be removed to process the excess adhesive. After cleaning, the adhesive receiving cup 14 can be reinstalled back onto the support plate 113.

[0033] Furthermore, the wiping head 122 is equipped with an absorbent sponge, which uses its absorbency to wipe the adhesive on the dispensing needle 23. After a certain period of use, the absorbent sponge on the wiping head 122 can be replaced.

[0034] Example 2

[0035] The dispensing device provided in this embodiment of the present invention includes the adhesive wiping mechanism 10 described in Embodiment 1. The adhesive wiping mechanism 10 in this application can promptly wipe away the adhesive residue retained by the dispensing needle 23, avoiding the problem of adhesive dripping and contaminating the dispensing needle 23.

[0036] Specifically, the dispensing device further includes a dispensing mechanism 20 and an adjusting mechanism 30. The dispensing mechanism 20 includes a cylinder 21, a fixed base 22, and a dispensing needle 23. The cylinder 21 is mounted on and rotatably connected to the fixed base 22, and the dispensing needle 23 is provided at the end of the cylinder 21. The adjusting mechanism 30 is mounted on the fixed base 22 and drives the cylinder 21 to rotate to achieve circumferential movement of the dispensing needle 23. In this embodiment, a control pump is provided inside the cylinder 21, and the adhesive inside the cylinder 21 can be pumped out from the dispensing needle 23 through the control pump. The adjusting mechanism 30 can be a robotic arm, or a transmission component such as a gear or pulley; the adjusting mechanism 30 only needs to be able to drive the cylinder 21 to rotate. When it is necessary to dispense adhesive onto the inner wall of the lens barrel, the dispensing needle 23 needs to be bent so that the end of the dispensing needle 23 is in close contact with the inner wall of the lens barrel. The adhesive liquid inside the barrel 21 is pumped out from the dispensing needle 23 by a control pump. After the barrel 21 rotates, it also rotates the dispensing needle 23, thereby completing one-circumference dispensing operation on the inner wall of the lens barrel.

[0037] Furthermore, the dispensing device also includes a temperature control component 40, which comprises a heating element and a temperature controller 41. The heating element is mounted on the cylinder 21, and the temperature controller 41 is electrically connected to the heating element and mounted on the fixed base 22. The heating element can be controlled by a controller to preset its temperature, ensuring that the adhesive maintains a certain fluidity at a suitable temperature and preventing the adhesive from solidifying due to excessively low temperatures. The temperature controller 41, mounted on the fixed base 22, can display the heating temperature of the heating element, facilitating real-time monitoring of the heating temperature.

[0038] Furthermore, the positioning component 50 is mounted on the fixed base 22 and located on one side of the cylinder 21. The positioning component 50 includes a CCD camera 51, which takes pictures and monitors the position of the dispensing needle 23 and transmits the monitoring results to the controller. The controller controls the cylinder 21 to move precisely, so that the dispensing needle 23 can be moved to the position where glue is to be applied.

[0039] Furthermore, the dispensing device also includes a movable slide rail 60, on which a drive motor is mounted. The drive motor drives the cylinder 21 to slide slidably connected to the movable slide rail 60. This facilitates the adjustment of the position of the cylinder 21, thereby enabling the dispensing needle 23 to perform dispensing operations on the lens barrel at different positions.

[0040] In this embodiment, when a dispensing operation is required, the dispensing needle 23 moves to a designated position, and the adhesive in the cylinder 21 can be pumped out from the dispensing needle 23 by a control pump. After the dispensing operation is completed, the dispensing needle 23 moves to the middle position between the two wiping heads 122. After being driven by the drive assembly 13, the two wiping heads 122 move closer to each other and abut against the dispensing needle 23, and the adhesive residue on the dispensing needle 23 is wiped away by the wiping heads 122. Furthermore, a receiving cup 14 is provided below the wiping head 122, which can collect the adhesive that falls from the dispensing needle 23 during the wiping process, preventing the adhesive from falling onto the worktable. The adhesive wiping mechanism 10 in this application can promptly wipe away the adhesive residue left on the dispensing needle 23, avoiding the problem of adhesive dripping and contaminating the dispensing needle 23.

[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
