Description

Technical Field

[0001] This utility model relates to the field of electronic equipment manufacturing technology, and in particular to an ultrasonic dispensing device. Background Technology

[0002] As a fundamental component of electronic devices, printed circuit boards (PCBs) face increasingly stringent quality and performance requirements. In the PCB manufacturing process, the potting process for the inner cover is a crucial step, enhancing the product's structural strength, sealing performance, electromagnetic compatibility, component stability, heat dissipation, aesthetics, and safety protection.

[0003] The existing method requires manually bending the cable backward to keep it away from the top of the inner cover when applying glue to the inner cover, and there is a lack of a simple and stable structure that can securely and accurately place the inner cover under the glue-applying head. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the need to manually bend the cable backward to keep it away from the top of the inner cover when applying glue to the inner cover, and the lack of a simple and stable structure that can securely and accurately place the inner cover under the glue-applying head. Therefore, this invention proposes an ultrasonic glue-applying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultrasonic dispensing device includes a main body.

[0007] Two material bins are used to store the main agent and the hardener, respectively, and both material bins are fixedly installed inside the main body of the equipment;

[0008] A mixing tank is used to mix the main agent and the hardener. The mixing tank is fixedly installed inside the main body of the equipment. Two metering pumps are fixedly installed inside the main body of the equipment. The input ends of the two metering pumps are connected to the two material tanks through pipes, and the output ends of the two metering pumps are connected to the mixing tank through pipes.

[0009] The dispensing head is used for dispensing glue. The dispensing head is located above the main body of the equipment. A second metering pump is fixedly installed inside the main body of the equipment. The input and output ends of the second metering pump are connected to the mixing tank and the dispensing head respectively through pipes.

[0010] A positioning element is used to position the inner cover. The positioning element is located on the top of the main body of the device and directly below the dispensing head.

[0011] In one possible design, a bracket is fixedly mounted on the top of the main body of the device, and the dispensing head is mounted on the bracket.

[0012] In one possible design, a servo motor is fixedly mounted on the top of the mixing tank, and an agitator is installed inside the mixing tank. The agitator's stirring rod rotates through the mixing tank and is fixedly mounted to the output shaft of the servo motor.

[0013] In one possible design, an ultrasonic generator is fixedly installed inside the main body of the device, and an ultrasonic transducer is installed inside the mixing tank, with the ultrasonic transducer cooperating with the ultrasonic generator.

[0014] In one possible design, the positioning element includes an upper ring and a movable half-ring. A fixed half-ring is fixedly disposed at the bottom of the upper ring and is fixedly disposed at the top of the main body of the device. The same inner ring is fixedly disposed at both ends of the movable half-ring. A concave surface is formed on the inner wall of the fixed half-ring, and the concave surface cooperates with the inner ring. A sliding rod is fixedly disposed at both ends of the movable half-ring, and the sliding rod slides through the fixed half-ring.

[0015] In one possible design, a compression spring is fitted on the outer wall of the slide rod, a fixing block is fixedly installed at one end of the slide rod, and the two ends of the compression spring are respectively fixedly installed on one side of the fixing block and the outer wall of the fixing half ring.

[0016] In one possible design, the bottom of the upper ring is provided with a notch.

[0017] In this application, during actual use, two metering pumps draw the main agent and hardener from the two material tanks into the mixing tank. A servo motor drives the agitator inside the mixing tank to rotate, thus achieving the mixing effect. By activating the ultrasonic generator, the ultrasonic transducer inside the mixing tank vibrates, further improving the mixing effect and efficiency. After mixing is complete, it can be extracted by a second metering pump and poured through the dispensing head. For the placement of the PCB board inner cover, the moving half-ring is first pulled out, at which point the compression spring is compressed. Then, the inner cover is placed between the moving half-ring and the inner ring, with the ribbon cable facing away from the upper ring. Then, the release is made, and the compression spring resets the inner cover. This completes the positioning and fixation of the inner cover, and the ribbon cable is located in the notch, achieving ribbon cable guidance and preventing it from affecting the dispensing operation if it is above the inner cover.

[0018] In this utility model, the ultrasonic dispensing equipment can perform ultrasonic treatment on the raw materials in the mixing tank through an ultrasonic generator, thereby further improving the mixing effect and improving the performance of the adhesive.

[0019] In this invention, the ultrasonic dispensing equipment uses a positioning component to accurately position the inner cover, ensuring the accuracy of the dispensing operation. The positioning component employs a combination of an upper circular ring and a movable semi-ring, making operation simple, convenient, and providing excellent positioning results.

[0020] In this invention, the inner cover is placed and glued using the positioning component, which facilitates positioning and fixing as well as guiding the wiring. This is convenient and eliminates the need for manual pressing of the wires, preventing the wires from bending above the inner cover and affecting the glue-filling process. It has the advantages of simple structure and easy operation. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1-2 An ultrasonic dispensing device, used in the field of electronic equipment manufacturing, includes: a main body 1, which serves as the supporting structure for the entire device. Two material tanks 2 are fixedly installed inside the main body 1. These two material tanks 2 are used to store the main agent and the hardener, respectively, ensuring the supply of raw materials required for the dispensing operation. A mixing tank 7 is also fixedly installed inside the main body 1. The mixing tank 7 is used to mix the main agent and the hardener. A feeding end with a valve is provided on the outer wall side of the material tank 2.

[0029] To transfer the raw materials from material tank 2 to mixing tank 7, two metering pumps 6 are fixedly installed inside the main body 1 of the equipment. The input ends of these two metering pumps 6 are connected to the two material tanks 2 respectively through pipes, while the output ends are connected to mixing tank 7 through pipes. In this way, the metering pumps 6 can quantitatively deliver the main agent and hardener from material tank 2 to mixing tank 7.

[0030] A dispensing head 3 is installed above the main body 1 of the equipment, which is used for dispensing glue. To ensure that the mixed glue can be smoothly delivered to the dispensing head 3, a second metering pump 9 is also fixedly installed inside the main body 1 of the equipment. The input end of the second metering pump 9 is connected to the mixing tank 7 through a pipe, and the output end is connected to the dispensing head 3 through a pipe.

[0031] Specifically, the main agent and hardener inside the two material tanks 2 are drawn into the mixing tank 7 by two metering pumps 6. The stirring inside the mixing tank 7 is driven by the servo motor 5 to achieve the mixing effect. After mixing is completed, it can be extracted by the second metering pump 9 and poured through the dispensing head 3.

[0032] Example 2

[0033] refer to Figure 3-4 Improvements based on Example 1: To position the inner cover and ensure the accuracy of the dispensing operation, a positioning component is provided at the top of the equipment body 1, directly below the dispensing head 3. The positioning component includes an upper ring 10 and a movable half-ring 15. A fixed half-ring 11 is fixedly installed at the bottom of the upper ring 10, and the fixed half-ring 11 is fixedly installed at the top of the equipment body 1. The same inner ring 14 is fixedly installed at both ends of the movable half-ring 15. A concave surface 17 is provided on the inner wall of the fixed half-ring 11, which cooperates with the inner ring 14. A sliding rod 13 is fixedly installed at both ends of the movable half-ring 15, and the sliding rod 13 slides through the fixed half-ring 11. To maintain the stability of the movable half-ring 15, a compression spring 12 is sleeved on the outer wall of the sliding rod 13. The two ends of the compression spring 12 are respectively fixedly installed on one side of the fixed block 18 and the outer wall of the fixed half-ring 11.

[0034] Specifically, for the placement of the inner cover of the PCB board, the movable half-ring 15 is first pulled out. In order to facilitate the movement of the movable half-ring 15, auxiliary parts such as pull rings can be set on its outer wall. At this time, the compression spring 12 will be compressed. Then, the inner cover is placed between the movable half-ring 15 and the inner ring 14, and the ribbon cable is oriented away from the upper ring 10. Then, the release can be used to reset the inner cover by the compression spring 12. At this time, the positioning and fixing of the inner cover can be completed, and the ribbon cable will be located in the recess 16 to guide the ribbon cable and avoid affecting the potting operation if it is above the inner cover.

[0035] Reference Figure 2 A bracket 4 is fixedly installed on the top of the main body 1 of the equipment, and the dispensing head 3 is installed on the bracket 4.

[0036] To improve the mixing effect, an ultrasonic generator 8 is fixedly installed inside the main body 1 of the equipment, and an ultrasonic transducer is installed inside the mixing tank 7. The ultrasonic transducer works in conjunction with the ultrasonic generator 8. When the ultrasonic generator 8 is activated, the ultrasonic transducer generates ultrasonic vibrations to ultrasonically treat the raw materials in the mixing tank 7, further improving the mixing effect.

[0037] However, as is well known to those skilled in the art, the working principles and wiring methods of the servo motor 5, the metering pump and the ultrasonic generator 8 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
