Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset chips, specifically a chip mounting device for processing Bluetooth headset chips. Background Technology

[0002] In the manufacturing process of Bluetooth headset chips, the surface mount technology (SMT) process plays a crucial role. It not only directly affects the overall quality of the product but also has a profound impact on production efficiency. The SMT process is the process of precisely attaching the chip to the circuit board. Any slight error or inaccuracy may lead to malfunctions or substandard performance of the headset during use.

[0003] Traditional Bluetooth headset chip processing and placement equipment typically employs a single-station design, requiring frequent manual replacement of the chip tray during operation. This not only increases the workload of operators but also prolongs tray replacement time, resulting in low overall production efficiency. Furthermore, existing equipment relies on simple mechanical slots or manual calibration for tray positioning, making it difficult to ensure precise positioning. Once the tray position deviates, it may lead to inaccurate chip placement, causing quality problems such as cold solder joints and short circuits, seriously affecting the processing quality of Bluetooth headset chips and increasing the defect rate. To address these issues, we propose a placement device for Bluetooth headset chip processing. Utility Model Content

[0040] Motor 4: The main body is columnar and fixed on the inner bottom surface of the workbench 1. The output shaft is connected to the rotary table 2 and serves as a power source to drive the rotary table 2 to rotate, thereby realizing the cyclic repositioning of the tray 3.

[0041] Limiting rod 5: It is a rod-shaped structure that can be inserted into the limiting hole 8 on the side of the worktable 1 and the limiting groove 10 on the annular protrusion 9 to fix the rotation angle of the rotary table 2, ensure that the tray 3 is in a precise position, and ensure the chip placement accuracy.

[0042] Circular hole 6: It is formed on the top surface of the worktable 1, and is circular in shape. It is used to insert the rotary table 2. It is the channel for the rotary table 2 to rotate and defines the installation position and movement trajectory of the rotary table 2.

[0043] Annular groove 7: It is formed on the cylindrical surface of the circular hole 6, and is in the shape of an annular ring. It cooperates with the annular protrusion 9 on the outer cylindrical surface of the rotary table 2 to enhance the stability of the rotary table 2 during rotation and reduce shaking.

[0044] Limiting hole 8: It penetrates the side of the worktable 1 to the annular groove 7, and is in the shape of a circular hole. It works with the limiting groove 10 and the limiting rod 5 to limit the rotation angle of the rotary table 2 and ensure the positioning accuracy of the tray 3.

[0045] Annular protrusion 9: Fixed on the outer cylindrical surface of the rotary table 2, it is an annular protrusion that cooperates with the annular groove 7 of the circular hole 6, making the rotation between the rotary table 2 and the circular hole 6 more stable and ensuring the smooth transportation of the pallet 3.

[0046] Limiting groove 10: It is formed on the outer cylindrical surface of the annular protrusion 9, and is in the shape of a circular groove with multiple circumferences evenly distributed. It is coaxial with the limiting hole 8 and is used to insert the limiting rod 5 to fix the position of the rotating table 2.

[0047] Insertion hole 11: penetrating the top surface of the rotary table 2, in the shape of a circular hole with three evenly distributed circumferences, used to insert the insertion rod 12 at the bottom of the tray 3, so as to realize the installation and positioning of the tray 3 on the rotary table 2;

[0048] Insert rod 12: Fixed on the bottom surface of tray 3, in the shape of a column, inserted into the insertion hole 11 of the rotating table 2 to support tray 3, while the spherical groove 13 on its outer cylindrical surface is used to cooperate with the snap-fit ​​structure to fix tray 3.

[0049] Spherical groove 13: It is formed on the outer cylindrical surface of the insertion rod 12 away from the tray 3, and is in the shape of a spherical groove with multiple circumferences evenly distributed. It is engaged with the arc-shaped end of the snap-fit ​​rod 16, and the snap-fit ​​structure is used to complete the fixing and disassembly of the tray 3.

[0050] Snap-fit ​​protrusion 14: It is fixed around the insertion hole 11 on the side of the rotary table 2 that connects to the motor 4. It has a block structure and a square groove inside for installing the spring 15 and the snap-fit ​​rod 16 to achieve snap-fit ​​fixation of the tray 3.

[0051] Spring 15: Installed in the square groove of the snap-fit ​​protrusion 14, one end is fixed on the side opposite to the opening of the square groove, and the other end is connected to the snap-fit ​​rod 16. The spring force causes the snap-fit ​​rod 16 to extend and snap into the spherical groove 13 to fix the tray 3.

[0052] The locking rod 16 has an arc shape at one end, which is connected to the spherical groove 13. The other end is connected to the spring 15. Under the action of the spring 15, the tray 3 can be locked and released, which facilitates the fixing and disassembly of the tray 3.

[0053] Working Principle: In the preparation stage, the Bluetooth headset chip to be processed is placed in tray 3. Then, the insertion rod 12 at the bottom of tray 3 is inserted into the insertion hole 11 on the rotary table 2. At this time, the spherical groove 13 on the outer cylindrical surface of insertion rod 12 is opposite to the snap-fit ​​rod 16 in the snap-fit ​​protrusion 14 on the rotary table 2. Under the action of the spring 15, the arc-shaped end of snap-fit ​​rod 16 is snapped into the spherical groove 13, completing the quick fixation of tray 3 on the rotary table 2. When chip placement is required, motor 4 is started. The output shaft of motor 4 drives the rotary table 2 to rotate in the circular hole 6. The annular groove 7 on the cylindrical surface of the circular hole 6 cooperates with the annular protrusion 9 on the outer cylindrical surface of the rotary table 2 to ensure the stability of the rotary table 2 during rotation and prevent the tray 3 from shifting due to shaking. When the rotary table 2 drives the tray 3 to the placement position of the placement machine, the operation... The operator inserts the limiting rod 5 into the limiting hole 8 on the side of the worktable 1 and the corresponding limiting groove 10 on the annular protrusion 9, limiting the rotation angle of the rotary table 2 and keeping the tray 3 in a precisely fixed state. This provides a stable foundation for chip placement and ensures that the chip can be accurately placed into the corresponding position on the circuit board. After placing the chip on one tray 3, the operator pulls out the limiting rod 5, starts the motor 4 again, and the rotary table 2 rotates, rotating the next tray 3 containing the chip to the placement position. The above limiting and placement operations are repeated to realize the sequential placement of multiple trays 3, which effectively improves the placement efficiency. When it is necessary to change to a different specification of tray 3, the operator presses the latching rod 16 to make it retract into the square groove to overcome the elastic force of the spring 15, and the tray 3 can be easily removed from the rotary table 2 and the new specification tray 3 can be installed. The operation is simple and meets the diverse production needs.
