This packaging technology has a relatively simple structure, is easy to manufacture, and has a relatively low cost. The shell provides good optical path alignment and protection, ensuring the stability and reliability of optical communication devices.

[0003] TO optical communication technology is applied in various fields, especially in data centers and 5G network technology. With the development of TO optical communication technology, the required precision is also increasing. It is necessary to attach chips at multiple angles in the TO base to meet the precision requirements. The existing product process is to manually attach the chips, which leads to reduced efficiency, increased labor costs, and easy deviation in the chip placement position, resulting in a very high chip damage rate. Utility Model Content

[0004] This utility model provides a multi-angle TO rotating head, which solves the technical problems of low chip placement efficiency, high labor costs, large placement errors, and high damage rates. The following technical solution is provided:

[0005] A multi-angle TO rotating head includes a bottom support plate, a main support plate fixedly mounted on one end of the top of the bottom support plate, a drive mechanism fixedly mounted on one side of the main support plate, an output shaft of the drive mechanism extending to the other end of the main support plate, and the output shaft of the drive mechanism and the main support plate being rotatably coupled. The head is characterized by further including an "L"-shaped connector, which is located on the other side of the main support plate. The vertical section of the connector is fixedly connected to the output shaft of the drive mechanism. An angle baffle is fixedly mounted on the section of the output shaft of the drive mechanism between the connector and the main support plate. An angle sensor for detecting the rotation angle of the angle baffle is mounted on the side wall of the main support plate near the connector.

[0006] The top of the horizontal section of the connector is provided with a TO base fixing fixture, and an origin stop post is fixedly provided on the outer wall of the TO base fixing fixture. A hollow shaft motor is fixedly provided at the bottom of the horizontal section of the connector. The output shaft of the hollow shaft motor is fixedly connected to the TO base fixing fixture, and the output shaft of the hollow shaft motor and the connector are in a rotating fit. The end of the output shaft of the hollow shaft motor away from the connector is connected to a rotary joint, and the other end of the rotary joint is used to connect to the vacuum circuit.

[0007] A slotted photoelectric sensor for detecting the rotation angle of the origin stop post is fixedly installed on the horizontal section of the connecting plate corresponding to one side of the TO base fixing fixture.

[0008] By adopting the above technical solution, through the setting of the drive mechanism and hollow shaft motor, the product to be mounted is vacuum-adsorbed by the TO base fixing fixture. At this time, the product is in the initial position. The pick-up structure can perform chip mounting operation on the top of the product. Before mounting, the position of the product can be adjusted by the hollow shaft motor. After mounting is completed, the drive mechanism is started to drive the connector and hollow shaft motor to rotate. At this time, the pick-up structure can mount the chip to other positions on the product, that is, the side wall surface of the product in the initial position. When one side wall surface of the product in the initial position is completed, the motor can be rotated in the opposite direction to mount the chip on the other side wall surfaces of the product in the initial position. Therefore, this device can complete the mechanical and automated mounting of chips in multiple positions on the product, thereby saving the cost and time spent on manual chip mounting, thus improving the efficiency of chip mounting and reducing labor input costs. Moreover, the position of the connector can be detected by the angle sensor to ensure the accuracy of the chip mounting position, reduce the situation of chip damage caused by deviation during mounting, thereby reducing the chip damage rate and reducing cost input.

[0011] Furthermore, the bottom of the third straight plate is provided with a second notch, and the shape of the second notch is suitable for the outer periphery of the rotary joint, so that the third straight plate is fixedly installed on the rotary joint.

A fourth notch is provided at the lower part of the connecting block, and the top of the fourth notch extends upward into the circular notch. The fourth notch extends towards the connector and into the third notch. A mounting hole is provided on the side wall of the connecting block perpendicular to the connector. The mounting hole passes through the fourth notch and extends out of the connecting block.

[0019] The sidewall of the angle baffle abuts against the sidewall of the connecting block. The angle baffle includes a connecting part and a test plate. The connecting part is fixedly sleeved on the output shaft of the drive mechanism in a circular shape. A section of the inferior arc surface on the outer periphery of the connecting part is fixedly connected to the test plate. The angle sensor is used to detect the rotation angle of the test plate.

[0020] By adopting the above technical solution, and by setting the circular notch, the third notch and the fourth notch, when it is necessary to install the connector on the output shaft of the drive mechanism, the circular notch is inserted into the output shaft of the drive mechanism, and bolts are tightened on the mounting holes. The structure is simple and the connector is firmly fixed on the output shaft of the drive mechanism. This reduces the installation difficulty and parts of the connector, thereby speeding up the disassembly and assembly speed and reducing the disassembly difficulty, thus saving costs.

The fixing member is provided along the outer periphery of the output shaft of the reducer, and the fixing member is compatible with the second groove.

[0026] By adopting the above technical solution and setting the fixing parts, the contact area between the reducer and the main support plate can be increased, thereby ensuring the connection stability between the reducer and the main support plate, thus extending the service life of the device and saving cost investment.

At this time, the product is in its initial position. The pick-up structure can perform chip mounting operations on the top of the product. Before mounting, the position of the product can be adjusted by the hollow shaft motor 8. After mounting is completed, the drive mechanism is activated to drive the connector 3 and the hollow shaft motor 8 to rotate. At this time, the pick-up structure can mount the chip to other positions on the product, i.e., the side wall surface where the product was in its initial position. After the chip is mounted on one side wall at the initial position of the product, the motor 25 can be rotated in the opposite direction to mount the chip on the other side walls at the initial position of the product.
