Description

Technical Field

[0001] This utility model relates to the field of connector manufacturing technology, specifically a connector rotation drive mechanism. Background Technology

[0002] Connectors, as key components for achieving electrical connections, are widely used in various electronic devices, communication systems, and automotive manufacturing industries. With the continuous upgrading and increasing complexity of electronic products, the performance and quality requirements for connectors are also rising. Furthermore, to facilitate production management, quality control, and subsequent use and maintenance, specifications and other information are typically engraved on the surface of connectors during the manufacturing process.

[0003] Laser engraving, as an advanced surface treatment process, is widely used for engraving specifications on connector surfaces due to its advantages such as high engraving precision, clear patterns, and wear resistance. During laser engraving, to ensure that the specifications are completely and accurately engraved around the entire circumference of the connector, it is necessary to drive the connector to rotate. Based on this, we propose a connector rotation drive mechanism for laser engraving equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connector rotation drive mechanism, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a connector rotation drive mechanism, including a drive motor, the drive end of the drive motor being connected to a main shaft, the end of the main shaft being connected to a chuck mounting seat, the end of the chuck mounting seat being connected to a pneumatic chuck, and the pneumatic chuck clamping and fixing the connector; a baffle is installed at the bottom end of the main shaft, and a photoelectric sensor is set directly below the baffle.

[0006] Furthermore, the connector rotation drive mechanism also includes a bracket, with an outer protective cover mounted on the side of the bracket, and the drive motor located inside the outer protective cover.

[0007] Furthermore, a base is installed on the side of the outer cover, a drive motor is installed on one side of the base, and the main shaft is rotatably connected to the inside of the base through bearings.

[0008] Furthermore, the surface of the outer cover is provided with several through holes, through which air is convected to carry away the heat generated by the drive motor during operation.

[0009] Furthermore, the drive motor is configured as a servo motor, capable of driving the spindle, chuck mounting base, and pneumatic chuck to rotate in either the forward or reverse direction.

[0010] Furthermore, when the drive motor drives the main shaft and the baffle to rotate synchronously, the baffle will pass through the inside of the photoelectric sensor.

[0011] This invention provides a connector rotation drive mechanism. Compared with the prior art, it has the following advantages:

[0012] Beneficial effects:

[0013] This connector rotary drive mechanism can precisely drive the connector to rotate stably for one full revolution, ensuring that the specifications and parameters are accurately and completely engraved all around the connector surface. This effectively avoids laser engraving quality defects caused by unstable rotation or inaccurate positioning, significantly improving the accuracy and quality of laser engraving of specifications and parameters on the connector surface. It meets the requirements of high precision and high stability for large-scale, automated production, thereby improving the connector's production efficiency and product qualification rate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a connector rotation drive mechanism, comprising a bracket 1, an outer protective cover 2, a drive motor 3, a base 4, a main shaft 5, a chuck mounting base 6, a pneumatic chuck 7, a connector 8, a baffle 9, and a photoelectric sensor 10. Specifically:

[0021] The drive motor 3, serving as the power source, is housed within the space enclosed by the outer casing 2. The outer casing 2 is securely supported by the bracket 1, and the side of the outer casing 2 is connected to the base 4. The drive motor 3 is mounted on one side of the base 4. The drive end of the drive motor 3 is directly connected to one end of the main shaft 5, providing power for the rotation of the main shaft 5.

[0022] The spindle 5 is located inside the base 4 and is rotatably connected to it via bearings. The bearings provide stable support and guidance for the rotation of the spindle 5, ensuring that the spindle 5 can rotate smoothly. The end of the spindle 5 furthest from the drive motor 3 is connected to the chuck mounting base 6. The chuck mounting base 6 serves as an intermediate connecting component, with one end firmly connected to the spindle 5 and the other end connected to the pneumatic chuck 7. The pneumatic chuck 7 is indirectly fixed to the spindle 5 through the chuck mounting base 6, and its interior forms a clamping space for clamping and fixing the connector 8.

[0023] A baffle 9 is installed at the bottom of the spindle 5. The baffle 9 is perpendicular to the spindle 5. A photoelectric sensor 10 is installed at the corresponding position directly below the baffle 9. The photoelectric sensor 10 is installed at the bottom inside the outer cover 2 to detect the position change of the baffle 9, thereby realizing the monitoring of the rotation angle or position of the spindle 5.

[0024] When the mechanism is in operation: Before starting work, ensure the entire mechanism is in normal working order. With the pneumatic chuck 7 in the released state, place the connector 8, to be laser-engraved, into the clamping space of the pneumatic chuck 7. Activate the pneumatic system (not shown in the figure), and the pneumatic chuck 7 actuates under air pressure to clamp and fix the connector 8, ensuring that the connector 8 will not loosen or shift during subsequent rotation. The pneumatic chuck 7 clamps the connector 8 through the pneumatic system, which is existing known technology and will not be described in detail here.

[0025] Start drive motor 3. As a servo motor, drive motor 3 can precisely control the rotation direction and angle. Drive motor 3 drives spindle 5 to rotate inside base 4. The rotation of spindle 5 causes chuck mounting base 6, pneumatic chuck 7 and clamped connector 8 to rotate forward as a whole.

[0026] During the rotation of connector 8, the laser engraving equipment starts and engraves the corresponding specifications around the surface of connector 8 according to a preset program. At this time, the baffle 9 at the bottom of the spindle 5 rotates synchronously with the spindle 5. Initially, the baffle 9 is located inside the photoelectric sensor 10. As the spindle 5 rotates, the baffle 9 gradually moves away from the photoelectric sensor 10. After connector 8 has rotated one revolution, the spindle 5 has also completed one revolution, and the baffle 9 returns to the inside of the photoelectric sensor 10. The photoelectric sensor 10 detects the change in the position of the baffle 9 and feeds back the signal to the control system (not shown in the figure). After receiving the signal from the photoelectric sensor 10, the control system controls the drive motor 3 to rotate in the opposite direction. The drive motor 3 drives the spindle 5, chuck mounting base 6, pneumatic chuck 7, and connector 8 to rotate in the opposite direction, causing the baffle 9 to return to the inside of the photoelectric sensor 10, completing the reset action. After the baffle 9 has completed its reverse rotation and returned to the inside of the photoelectric sensor 10, the control system controls the pneumatic chuck 7 to release connector 8. The operator removes the laser-engraved connector 8 and replaces it with the next connector 8 requiring surface laser engraving. After replacing connector 8, the initial preparation, forward rotation and laser engraving, reverse rotation and reset steps are repeated in a cyclical manner. Although the pneumatic chuck 7 is connected to an air hose during operation, this alternating forward and reverse rotation method prevents the air hose from becoming tangled. As long as the air hose is long enough for the pneumatic chuck 7 to rotate one revolution, the entire mechanism can operate stably, achieving efficient and stable laser engraving of the connector surface.

[0027] Finally, it should be noted that the servo motor, pneumatic chuck 7, photoelectric sensor 10 and control system involved in this embodiment are all technologies well known to those skilled in the art, and their structures, principles, control structures and circuit structures will not be described here.
