Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lens processing technology, and specifically refers to an automatic glue dispensing device. Background Technology
[0002] During lens manufacturing, optical adhesives are used to bond different materials together. Sometimes, two or more types of optical adhesives need to be mixed together in a predetermined ratio to achieve the desired bonding effect.
[0003] Currently, different optical adhesives are mainly mixed manually by pouring them into containers and stirring them evenly before loading them into a dispensing machine. This process may result in common manual problems such as insufficient stirring and errors in the mixing ratio. Utility Model Content
[0004] The main purpose of this invention is to provide an automatic adhesive mixing device that solves the problems existing in the prior art, and can automatically mix different adhesives to achieve automation.
[0005] To achieve the above objectives, the solution of this utility model is:
[0006] An automatic glue dispensing device includes two feed cups, a mixing cup, a storage cup, a cup lid, a stirring motor, a solenoid valve, a first defoaming filter, a second defoaming filter, and a switching valve. The bottoms of the two feed cups are connected to the side of the mixing cup via pipes, and the bottom of the mixing cup is connected to the side of the storage cup via a pipe. Each feed cup, mixing cup, and storage cup has a sealed cup lid at its upper opening. A stirring motor is mounted on the cup lid above the mixing cup, and the stirring shaft of the motor passes into the mixing cup. Several stirring blades are arranged on the circumference of the stirring shaft. A solenoid valve is installed on the pipe between the feed cups and the mixing cup. A first defoaming filter is installed on the pipe between the mixing cup and the storage cup. A second defoaming filter is installed at the bottom of the storage cup. Several liquid outlets are provided at the bottom of the storage cup, and each liquid outlet is equipped with a switching valve.
[0007] An ultrasonic liquid level sensor is installed on the lid of both the feed cup and the storage cup.
[0008] Both the feed cup and the storage cup are equipped with exhaust pipes on their respective cup lids.
[0009] Both the feed cup and the storage cup have cup lids with handles.
[0010] A positioning tenon is provided between the cap of the plastic cup and the circumferential surface of the corresponding opening end of the plastic cup, and the positioning tenon is inserted into the groove on the circumferential surface of the plastic cup.
[0011] Flow meters are installed on the pipes between the feed cup and the mixing cup.
[0012] The lid of the mixing cup is provided with a through hole for the stirring shaft of the stirring motor to pass through, and the surface of the through hole is covered with a dustproof rubber cover.
[0013] A solenoid valve is also installed on the pipe between the mixing cup and the storage cup.
[0014] After adopting the above technical solution, the present invention has the following technical effects:
[0015] The two feeding cups of this invention can be filled with different optical adhesives according to production needs. By controlling the different opening degrees of the two solenoid valves, different flow rates of optical adhesive can be fed into the mixing cup to achieve proportional mixing. The storage cup and the mixing cup are used for storage and mixing, respectively. The mixed optical adhesive first passes through the first defoaming filter into the storage cup, and then passes through the second defoaming filter to be discharged from the outlet, ensuring that no air bubbles are mixed in the adhesive and ensuring the dispensing quality of subsequent processes. The multi-outlet design allows multiple dispensing machines to share the same storage cup, saving equipment costs. Attached Figure Description

Detailed Implementation
[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0021] refer to Figure 1-2 As shown, this utility model discloses an automatic glue dispensing device, including two feeding glue cups 1, a mixing glue cup 2, a storage glue cup 3, a glue cup lid 4, a stirring motor 5, a solenoid valve 6, a first defoaming filter 7, a second defoaming filter 8, and a switching valve 9.
[0022] The bottoms of the two feeding cups 1 are connected to the side of the mixing cup 2 via pipes, and the bottom of the mixing cup 2 is connected to the side of the storage cup 3 via pipes; the upper openings of the feeding cup 1, the mixing cup 2, and the storage cup 3 are all sealed with cup lids 4.
[0023] A stirring motor 5 is installed on the cup lid 4 above the mixing cup 2. The stirring shaft 51 of the stirring motor 5 is inserted into the mixing cup 2. Several stirring blades 52 are provided on the circumference of the stirring shaft 51.
[0024] A solenoid valve 6 is installed on the pipe between the feeding cup 1 and the mixing cup 2;
[0025] A first defoaming filter 7 is installed on the pipe between the mixing cup 2 and the storage cup 3; a second defoaming filter 8 is installed at the bottom of the storage cup 3.
[0026] The bottom of the storage cup 3 is provided with several liquid outlets 31, and each liquid outlet 31 is equipped with a switch valve 9.
[0027] Through the above scheme, the two feeding cups 1 of this utility model can be filled with different optical adhesives according to production needs. By controlling the different opening degrees of the two solenoid valves 6, different flow rates of optical adhesive can be input into the mixing cup 2 to achieve proportional mixing. The storage cup 3 and the mixing cup 2 are used for storage and mixing, respectively. The mixed optical adhesive first passes through the first defoaming filter 7 into the storage cup 3, and then passes through the second defoaming filter 8 to be discharged from the outlet 31, ensuring that no air bubbles are mixed in the adhesive and ensuring the dispensing quality of the subsequent process. The design of multiple outlets 31 allows multiple dispensing machines to share the same storage cup 3, saving equipment costs.
[0028] The following are specific embodiments of the present invention.
[0029] An ultrasonic liquid level sensor 10 is installed on the glue cup cover 4 above the above-mentioned feed glue cup 1 and storage glue cup 3 to detect the amount of glue in the feed glue cup 1 / storage glue cup 3 so that the material can be replenished at any time.
[0030] The above-mentioned feed cup 1 and storage cup 3 are both equipped with exhaust pipes 41 on the cup lids 4 to discharge the gas inside the cups.
[0031] The above-mentioned feeding cup 1 and storage cup 3 are both equipped with cup lid handles 42 on the cup lids 4, which make it easy to open the cup lids 4.
[0032] A positioning tenon 43 is provided between the aforementioned glue cup lid 4 and the circumferential surface of the opening end of the corresponding glue cup (including feeding glue cup 1, mixing glue cup 2 and storage glue cup 3) to ensure that the glue cup lid 4 will not rotate after being assembled in place; the positioning tenon 43 is inserted into the groove provided on the circumferential surface of the glue cup.
[0033] A flow meter 20 is installed on the pipeline between the feed cup 1 and the mixing cup 2 to monitor the liquid flow rate in the pipeline to ensure that it meets the mixing ratio requirements and to open and close the solenoid valve 6 on the corresponding pipeline in a timely manner.
[0034] A solenoid valve 6' is also installed on the pipeline between the mixing cup 2 and the storage cup 3, so that the corresponding solenoid valve 6' is automatically closed after the glue in the mixing cup 2 is emptied, such as by controlling the solenoid valve 6' through a time relay.
[0035] The above-mentioned mixing cup 2 has a cup cover 4 with a through hole 44 for the stirring shaft 51 of the stirring motor 5 to pass through. The surface of the through hole 44 is covered with a dustproof rubber cover 30 to prevent dust from entering the mixing cup 2.
