Description

Technical Field

[0001] This utility model belongs to the field of dual-component glue dispensing, and in particular relates to a two-component AB glue bucket anti-reverse device. Background Technology

[0002] In the 3C electronics manufacturing industry, two-component AB adhesives (such as epoxy resin adhesives and polyurethane adhesives) are widely used in structural bonding, sealing, and potting processes. These adhesives consist of component A (resin) and component B (curing agent), and must be mixed in the correct proportions to cure properly. Therefore, in automatic dispensing equipment, component A and component B must be added separately to their respective dispensing containers and extracted using a dedicated suction rod.

[0003] However, in practice, the following technical problems exist: 1. Manual glue addition is prone to errors: When changing or adding glue, operators may mistakenly add glue A to glue B or vice versa, resulting in incorrect glue mixing ratios and causing quality problems such as product bonding failure and incomplete curing.

[0004] 2. Incorrect installation of glue suction rods: If glue suction rod A and glue suction rod B are installed incorrectly, it will cause the wrong glue to be drawn, which will also disrupt the mixing ratio and affect the production yield.

[0005] 3. Lack of automatic identification and alarm mechanism: Traditional glue supply systems rely on manual verification and lack automatic detection function. Errors are difficult to detect in time and are often only discovered after a period of production, resulting in batch scrap.

[0006] 4. Low level of equipment intelligence: Existing equipment cannot automatically identify and provide status feedback for glue buckets and suction rods, and cannot be linked with the control system to provide abnormal prompts or shutdown protection.

[0007] Although some devices are distinguished by labels or numbers, they still rely on manual judgment and cannot fundamentally eliminate misoperation.

[0008] Therefore, there is an urgent need for a simple, accurate, and timely anti-reverse device for two-component AB glue buckets to solve the above problems. Utility Model Content

[0009] The purpose of this invention is to provide a two-component AB glue bucket anti-reverse device to solve problems such as incorrect glue addition to the A / B glue buckets and incorrect installation of the suction rod caused by manual operation in the prior art. By setting different color markings on the glue bucket and the suction rod, and using color sensors for automatic identification, the device can intelligently determine the placement position of the glue bucket and the installation status of the suction rod. Once an abnormality is detected, an automatic alarm is triggered to prevent incorrect glue from entering the system, ensuring production quality and stable equipment operation.

[0010] The technical solution provided by this utility model is as follows: A two-component AB glue bucket anti-reverse device, comprising an A glue supply bucket, a B glue supply bucket, a glue bucket support, a first color sensor, a second color sensor, an A suction rod, and a B suction rod; the A glue supply bucket and the B glue supply bucket are placed on the glue bucket support, and the first color sensor is respectively provided below the A glue supply bucket and the B glue supply bucket to detect the color of the glue bucket and determine whether the placement position is correct; the A suction rod and the B suction rod are respectively inserted into the A glue supply bucket and the B glue supply bucket, and the second color sensor is respectively provided below the A suction rod and the B suction rod to detect the color of the suction rod and determine whether the installation is correct.

[0011] Preferably, both the first color sensor and the second color sensor are photoelectric color sensors, and their output signals are connected to the device control system.

[0012] Preferably, two first color sensors are installed on the bottom side of the glue bucket bracket, one of which detects the color of glue bucket A; the other detects the color of glue bucket B.

[0013] Preferably, the A glue supply bucket and the A glue suction rod are the same color, and the B glue supply bucket and the B glue suction rod are the same color; however, the A glue supply bucket and the B glue supply bucket are different colors.

[0014] Preferably, an A-type adhesive suction rod bracket and a B-type adhesive suction rod bracket are also provided; the adhesive bucket bracket is fixedly connected to the A-type and B-type adhesive suction rod brackets respectively; the A-type and B-type adhesive suction rod brackets have identical structures. This ensures that the color sensor is aligned with the detection positions of the adhesive bucket and the adhesive suction rod.

[0015] Preferably, the adhesive suction rod bracket is stepped, with its bottom fixed to the other side of the bottom of the glue bucket bracket, its middle fixed to the upper surface of the glue bucket bracket, and its upper part in contact with the surface of glue bucket A or glue bucket B; a U-shaped groove is provided on the upper part of the adhesive suction rod bracket, which is the mounting position for the second color sensor.

[0016] Preferably, the outer surfaces of the first color sensor and the second color sensor are each provided with a protective cover to prevent glue splashing from affecting the detection accuracy.

[0017] The advantages over existing technologies are: 1) Strong error prevention capability: Through color marking and automatic sensor identification, the misinstallation of A / B glue buckets and glue suction rods is fundamentally eliminated, avoiding product defects caused by incorrect glue ratio.

[0018] 2) High level of intelligence: The system can automatically determine the installation status of the glue bucket and the glue suction rod, eliminating the need for manual verification and improving the automation level of the equipment.

[0019] 3) Timely response: Once an incorrect installation is detected, an alarm or shutdown is triggered immediately to prevent the error from continuing and reduce material waste and batch scrapping.

[0020] 4) Simple structure and low cost: It only requires adding color markings and color sensors to the existing glue supply system, which is low-cost and easy to implement and promote.

[0021] 5) Easy maintenance: The color sensor is installed in a reasonable position, which does not affect normal glue application and maintenance operations, and can be seamlessly integrated with the equipment control system. Attached Figure Description

When a component is described as being "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "fixed," "integral," "left," "right," and similar expressions used in this specification are for illustrative purposes only, and in the figures, structurally similar units are labeled with the same reference numerals.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0027] like Figure 1-2 As shown, one embodiment of this utility model is: a two-component AB glue bucket anti-reverse device, mainly including an A glue supply bucket 1, a B glue supply bucket 5, a glue bucket bracket 3, a glue suction rod bracket and a color sensor, wherein the glue suction rod bracket includes an A glue suction rod bracket 3 and a B glue suction rod bracket 7; the color sensor includes a first color sensor 4 and a second color sensor 9.

[0028] In this embodiment: A glue supply bucket 1 is red and is used to hold glue A. B glue supply bucket 5 is blue and is used to hold B glue; Glue supply bucket 1 (A) and glue supply bucket 5 (B) are placed in their designated positions on the glue bucket bracket 3.

[0029] Directly below the glue bucket bracket 3, corresponding to the installation positions of glue supply bucket A 1 and glue supply bucket B 5, a first color sensor 4 is installed on each bucket. Once the glue buckets are in place, the first color sensor 4 automatically detects the color of their bottom. If glue supply bucket 1 is placed at position A, the sensor detects red → judgment is correct; If glue supply bucket 5 (B) is placed at position A, the sensor will detect a blue color → indicating an error and triggering an alarm.

[0030] Similarly: A suction rod 2 is red and is inserted into A glue supply bucket 1; B suction rod 6 is blue and is inserted into B glue supply tank 5; The adhesive suction rod bracket is used to support the adhesive suction rod, and a second color sensor 9 is also installed below it to detect the color of the lower part of the adhesive suction rod.

[0031] After the adhesive suction stick is installed, the color sensor detects its color: If adhesive suction rod 2 (A) is inserted into adhesive supply tank 1 (A), the sensor detects red → judgment is correct; If glue suction rod 6 (B) is mistakenly inserted into glue supply tank 1 (A), the sensor will detect a blue light, indicating an error and triggering an alarm.

[0032] The output signals of the first color sensor 4 and the second color sensor 9 are connected to the equipment PLC or control system. Once an abnormality is detected, the HMI interface will immediately prompt "Incorrect placement of glue bucket" or "Incorrect installation of glue suction rod", and the machine can be selectively stopped to prevent the error from continuing.

[0033] This invention has been applied in a 3C electronic product potting production line, effectively eliminating potting errors caused by manual operation and improving product yield by more than 98%.

[0034] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
