Description

Technical Field

[0001] This utility model specifically relates to the field of vacuum dispensing machine technology, and more specifically to a frameless torque motor vacuum dispensing machine for robot joint modules. Background Technology

[0002] In the field of robot joint modules, torque motors are core drive components, currently mainly divided into two types: framed torque motors and frameless torque motors. Among them, existing framed torque motors have significant drawbacks: compared to frameless torque motors, framed torque motors have a larger diameter and volume, resulting in greater space requirements during robot joint module assembly and poor installation convenience; simultaneously, framed torque motors have lower torque output, making it difficult to meet the operational needs of some high-precision, high-load robot joints, and their stability during operation is insufficient, making them prone to failure.

[0003] From a structural perspective, framed torque motors have a complex structure, containing a large number of components and complicated connections between them. This not only increases the difficulty of component processing but also makes the assembly process time-consuming and labor-intensive, requiring higher assembly precision control, ultimately resulting in higher production and manufacturing costs for framed torque motors.

[0004] While frameless torque motors offer advantages over framed torque motors in terms of size, torque, and installation flexibility, their structural characteristics significantly increase the difficulty of designing suitable potting fixtures. Existing potting equipment and fixtures are insufficient to meet the sealing and potting requirements of frameless torque motors. Conventional potting methods are prone to problems such as glue leakage and uneven potting, affecting the insulation performance and service life of the frameless torque motor. Therefore, there is an urgent need to design a highly efficient and reliable vacuum potting machine and matching potting fixture specifically for frameless torque motors. Utility Model Content

[0009] As a further technical solution of this utility model, a silicone sleeve is also included. The silicone sleeve is adapted to the frameless motor and is used to assist in the positioning and sealing of the frameless motor, further improving the sealing performance of the fixture and preventing glue leakage.

[0010] As a further technical solution of this utility model, it also includes a pressure plate, which is correspondingly arranged with the frameless motor to press and fix the frameless motor in the fixture, so as to prevent the frameless motor from shifting during the glue dispensing process and ensure glue dispensing accuracy.

The material preparation unit 1 is located at the rear of the vacuum chamber 2. The dispensing head 3 is located above the vacuum chamber 2 and extends through the vacuum chamber 2 into its interior. The vacuum pump 4 is installed on the right side of the vacuum chamber 2. The frameless motor fixture 5 is installed on a portion of the profile extending from the bottom of the vacuum chamber 2 and is used to fix the frameless motor 55 to be dispensed with glue. The frameless motor fixture 5 includes a base plate 51, which is used to fix a tooling side plate 57 and a tooling side plate 58.

A mandrel 54 is installed on the mandrel base 53, which is used to seal the inner ring of the frameless motor 55. It also includes a silicone sealing gasket 52, which is installed on the base plate 51 and located at the connection position between the base plate 51 and the tooling side plate 1 57 and the tooling side plate 2 58, and is used to seal the tooling side plate 1 57 and the tooling side plate 2 58 to prevent glue leakage during the glue pouring process.

[0022] By adopting the above technical solution, during use, on the one hand, the frameless motor fixture 5 seals the outer ring of the frameless motor 55 through tooling side plate 1 57 and tooling side plate 2 58, and the mandrel 54 seals the inner ring of the frameless motor 55. Combined with silicone sealing gasket 52 and silicone sleeve 56, multiple seals are achieved, which completely solves the problem of glue leakage during the glue pouring process and ensures the glue pouring quality. On the other hand, the pressure plate 59 in the fixture can firmly fix the frameless motor 55 to prevent the motor from shifting during glue pouring. At the same time, the vacuum chamber 2 forms a stable vacuum environment under the action of vacuum pump 4, which reduces the generation of air bubbles during glue pouring, makes glue pouring more uniform, and thus improves the stability of the frameless motor 55 during operation and reduces the failure rate.

[0023] In this embodiment, a silicone sleeve 56 is also included. The silicone sleeve 56 is adapted to the frameless motor 55 and is used to assist in the positioning and sealing of the frameless motor 55, further improving the sealing performance of the fixture and preventing glue leakage.

[0024] By adopting the above technical solution, the improved glue dispensing quality avoids rework or scrapping of the frameless motor 55 due to glue dispensing problems, extends the service life of the frameless motor 55, and indirectly reduces the overall usage cost of the robot joint module. In addition, the frameless motor 55 itself is smaller in size and has greater torque than the framed motor. When paired with the glue dispensing machine of this application, it can better exert its performance advantages and improve the overall cost performance of the robot joint module.

[0025] In this embodiment, a pressure plate 59 is also included. The pressure plate 59 is correspondingly arranged with the frameless motor 55 and is used to press and fix the frameless motor 55 in the fixture to prevent the frameless motor 55 from shifting during the glue dispensing process and to ensure glue dispensing accuracy.

[0026] By adopting the above technical solution, the frameless motor fixture 5 is specially designed for the frameless motor 55. The various components of the fixture, such as the base plate 51, the mandrel 54, the tooling side plate 1 57, and the tooling side plate 2 58, can be adapted and adjusted according to the size of different models of frameless motors 55. It has a wide range of adaptability and can meet the potting requirements of various robot joint module frameless motors 55. It is highly practical and can be widely used in the field of robot manufacturing.

[0027] The working principle of this utility model is as follows: start the vacuum pump 4, the vacuum pump 4 performs a vacuuming operation on the inside of the vacuum chamber 2, and discharges the air inside the chamber until the chamber reaches the preset vacuum level, so as to provide a vacuum environment without air bubbles to prevent air bubbles from appearing inside the frameless motor 55 after the glue is poured, thus avoiding affecting the performance. The material preparation unit 1 delivers the required glue to the dispensing head 3 according to the preset material ratio and supply quantity. Under the control of the control system, the dispensing head 3 passes through the top of the vacuum chamber 2 and is aligned with the dispensing area of ​​the frameless motor 55 fixed in the fixture 5, and evenly injects the glue into the designated position of the frameless motor 55. During the dispensing process, the multiple sealing structure of the fixture 5 ensures that the glue will not leak, while the vacuum environment ensures that the glue is fully filled and free of air bubbles. After the glue dispensing operation is completed, maintain the vacuum state of the vacuum chamber 2 for a period of time to allow the glue to fully wet the frameless motor 55 and cure it; then turn off the vacuum pump 4, slowly restore the air pressure inside the vacuum chamber 2 to normal pressure, and finally open the vacuum chamber 2, take out the frameless motor 55 and fixture 5 after glue dispensing, disassemble the fixture 5 and take out the frameless motor 55 after glue dispensing to complete the entire glue dispensing process. During use, on the one hand, the frameless motor fixture 5 seals the outer ring of the frameless motor 55 through tooling side plate 1 57 and tooling side plate 2 58, and the mandrel 54 seals the inner ring of the frameless motor 55. Combined with silicone sealing gasket 52 and silicone sleeve 56, multiple seals are achieved, which completely solves the problem of glue leakage during the glue dispensing process and ensures the quality of glue dispensing. On the other hand, the pressure plate 59 in the fixture can firmly fix the frameless motor 55 to prevent the motor from shifting during glue dispensing. At the same time, the vacuum chamber 2 forms a stable vacuum environment under the action of vacuum pump 4, which reduces the generation of air bubbles during glue dispensing, makes glue dispensing more uniform, and thus improves the stability of the frameless motor 55 during operation and reduces the failure rate. The improved glue-filling quality avoids rework or scrapping of the frameless motor 55 due to glue-filling problems, extends the service life of the frameless motor 55, and indirectly reduces the overall cost of using the robot joint module. In addition, the frameless motor 55 itself is smaller in size and has greater torque than the framed motor. When paired with the glue-filling machine of this application, it can better exert its performance advantages and improve the overall cost-effectiveness of the robot joint module. The frameless motor fixture 5 is specifically designed for the frameless motor 55. The various components of the fixture, such as the base plate 51, mandrel 54, tooling side plate 1 57, and tooling side plate 2 58, can be adapted and adjusted according to the size of different models of frameless motors 55. It has a wide range of adaptability and can meet the potting requirements of various robot joint module frameless motors 55. It is highly practical and can be widely used in the field of robot manufacturing.
