Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic assembly device for smoke detectors. Background Technology

[0002] Smoke detectors, as an important fire safety device, are widely used in homes, office buildings, and industrial sites. The market demand is huge, and the requirements for product quality are extremely high. The internal structure of a smoke detector is relatively complex, typically consisting of multiple components such as a base shell, PCB circuit board, round cover, top cover, and light guide column. The assembly quality of these components, especially the alignment accuracy of the optical components and the circuit board, directly affects the sensitivity and operational stability of the alarm.

[0003] However, in the current manufacturing process of smoke detectors, the vast majority of assembly processes still rely on manual operation or the use of scattered semi-automated equipment. This traditional production model has obvious limitations: on the one hand, because the assembly processes of each component (such as bottom shell loading, PCB board installation, and top cover pressing) are relatively independent, the processes often need to be transferred manually or asynchronously via conveyor belts, resulting in a discontinuous overall production cycle and making it difficult to achieve high-speed, large-scale assembly line production, which seriously restricts the improvement of production capacity.

[0004] On the other hand, with increasing demands for product precision, especially for precise PCB board positioning and the insertion and assembly of tiny light guides, relying solely on manual labor or simple tooling makes it difficult to guarantee a high degree of consistency. Manual operation is not only prone to fatigue leading to misassembly or omissions, but also susceptible to damage when pressing tiny components, resulting in significant fluctuations in product yield. Furthermore, decentralized work layouts occupy a large area, and the lack of a unified central integrated control and automated workflow mechanism prevents the formation of a compact and efficient automated closed loop, increasing production management and labor costs.

[0005] Therefore, this utility model proposes an automatic assembly device for smoke detectors to overcome the shortcomings of the prior art. Utility Model Content

[0026] Please refer to Figures 1 to 10This utility model provides an automatic assembly equipment for smoke detectors, which aims to solve the structural defects in the existing technology where the assembly process of smoke detectors relies too much on manual or semi-automatic equipment, resulting in low production efficiency, poor consistency of component assembly accuracy, and difficulty in achieving high-speed fully automated production.

[0027] like Figure 1 and Figure 2 As shown, the automatic assembly equipment for the smoke detector includes a lower frame base 2 and an assembly platform 11 fixedly installed on the upper surface of the lower frame base 2.

A first camera light source 406 and a second camera light source 407 are fixedly mounted on the top of the grasping area via a bracket. The first camera light source 406 and the second camera light source 407, together with the vision system, can capture the feature points of the PCB board on the PCB board waiting position 402. The four-axis robot 408 picks up the PCB board through the suction cup at its end according to the visual coordinates.

The first vibration table 501 conveys the bottom shell into the first primary positioning component 503 for coarse positioning through vibration. The first linear module 506 drives the first electric cylinder 505 and the first rotary clamping pneumatic claw 504 to move above the first primary positioning component 503 to grab the bottom shell. Then, it moves to the vision detection position powered by the camera power supply 509 to take pictures and correct the bottom. Finally, it is accurately placed in the bottom shell assembly station 508 on the assembly machine 11. The first linear module 506, the first electric cylinder 505 and the first rotary clamping pneumatic claw 504 constitute a three-axis linkage gripping and transfer mechanism, which ensures the high efficiency and accuracy of bottom shell loading.

[0033] Working principle: When the equipment starts to carry out automated production, the controller 3 issues instructions to coordinate the operation of each component. The material tray conveyor line 403 transports the material tray loaded with PCB boards to the PCB board waiting position 402. The first camera light source 406 and the second camera light source 407 work together with the vision system to identify the position and correct the angle of the PCB board. The four-axis robot 408 takes out the PCB board with a suction cup and accurately places it on the PCB board assembly 1104 station on the turntable of the assembly machine 11. The empty tray is returned via the empty tray conveyor line 401. Meanwhile, the first vibration table 501 transports the bottom shell in an oriented arrangement to the first primary positioning component 503. The first electric cylinder 505 drives the first rotary clamping gripper 504 to grab the bottom shell. The first linear module 506 drives the first electric cylinder 505 to move to the camera detection position. After the angle is corrected with the assistance of the vision system powered by the camera power supply 509, the bottom shell is accurately placed into the bottom shell assembly body 1105 station. As the cam divider 1107 drives the turntable to rotate, the bottom shell and PCB board complete the initial assembly. Subsequently, the first vibratory feeder 701 transports the round cover to the second primary positioning component 708. The second electric cylinder 703 drives the gripper body 707 to grasp the round cover. The third linear module 704 drives the component to move above the first assembly station 706 to complete the placement and assembly of the round cover. The second vibratory table 801 transports the upper cover to the third primary positioning component 808. The third electric cylinder 803 drives the second rotary clamping pneumatic gripper 802 to grasp the upper cover. The fourth linear module 804 moves the component to the third camera light source 807 for high-precision visual alignment and rotation correction, and then moves it above the second assembly station 806 to complete the assembly. The light guide column is then pressed into place. Next, the second vibratory feeder 903 transports the light guide column to the fourth primary positioning component 908. The fourth electric cylinder 905 drives the rotary clamping cylinder 902 to grab the light guide column. The fifth linear module 901 moves the component to the area of ​​the fourth camera light source 907 to identify the direction and correct it. At the third assembly station 906, the light guide column is inserted into the guide hole of the upper cover to complete the initial assembly. The cam divider 1107 continues to drive the turntable to rotate to the final assembly station 1108 of the light guide column. The pressing cylinder 1002 descends vertically and, supported by the fifth fixed bracket 1001, presses the light guide column completely into the interior of the upper cover to achieve locking. Finally, after all processes are completed, the second linear module 601 drives the gripping cylinder 604 and the cylinder gripper 605 to grab the assembled smoke detector from the finished product output 1106 station, move it horizontally and place it on the finished product conveyor line 606 for output, realizing fully automated cyclic production.
