It is used in alarms, electronic toys, and automotive electronic devices. It can convert electrical signals into sound signals to realize audible and visual alarms and reminders. Buzzer assembly equipment is a special mechanical equipment used to automate or semi-automatically assemble the various components of a buzzer. It covers multiple functional modules such as feeding, handling, and positioning, aiming to replace traditional manual assembly methods and improve the production efficiency and product quality stability of buzzers.

[0003] A search revealed Chinese patent publication number CN217096531U, which discloses a novel buzzer assembly device. The device includes a workbench equipped with a material transmission mechanism, a top-feeding mechanism, a first feeding mechanism, a second feeding mechanism, and a mounting platform. The mounting platform is located between the material transmission mechanism and the top-feeding mechanism. This device uses the top-feeding mechanism to eject the buzzer material, which is then moved to the mounting platform by the second feeding mechanism. The first feeding mechanism, in conjunction with the material transmission mechanism, moves the buzzer to the mounting platform, where the buzzer material is embedded. This achieves automated assembly, improves production efficiency, and saves manpower. However, in actual use, the buzzer assembly process involves compression, which can damage the diaphragm and lead to a decrease in production quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a buzzer assembly device, which aims to improve the problem that the diaphragm is damaged and the production quality is reduced when the buzzer is assembled by extrusion in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a buzzer assembly device, including a platform, a movable component on the top of the platform, a workbench fixed on the top of the movable component, multiple tooling fixtures slidably connected to the top of the workbench, a support frame fixedly connected to the rear right side of the top of the platform, an adjustment component on the top of the support frame, a movable frame fixedly connected to the left side of the adjustment component, an air pump one fixedly connected to the top left side of the movable frame, the output end of the air pump one passing through the movable frame and fixedly connected to a push rod, an L-shaped plate fixedly connected to the bottom of the push rod, a gripping tube fixedly connected to the top left side of the L-shaped plate, the bottom end of the gripping tube passing through the L-shaped plate, a negative pressure fan fixedly connected to the right side of the movable frame, a negative pressure pipe connected to one side of the negative pressure fan, the other end of the negative pressure pipe connected to the top of the gripping tube, and a feeding component provided on the front side of the top of the platform.

[0006] Through the above technical solution: when the workbench is in place, the adjustment component on the top of the support frame is activated, the motor in the adjustment component runs, and its output end drives the threaded rod to rotate in the sliding groove two. The sliding block two, which is threadedly connected to the threaded rod, moves along the sliding groove two under the drive of the threaded rod, thereby driving the moving frame fixed on the left side of the sliding block two to move above the feeding component. After the moving frame is in place, the air pump one on the top left side of the moving frame is activated, and its output end pushes the push rod down. The L-shaped plate fixed at the bottom of the push rod and the gripping tube on the top left side of the L-shaped plate descend accordingly. At the same time, the negative pressure fan on the right side of the moving frame is activated, and negative pressure is generated in the gripping tube through the negative pressure pipe. When the gripping tube descends to contact the parts in the feeding component, it grips the parts. Then, the air pump one contracts, driving the gripping tube to rise. The adjustment component operates again, and the moving frame moves the gripped parts to a suitable position above the workbench fixture. The negative pressure fan stops working, the gripping tube loses negative pressure, and the parts are accurately placed on the fixture. By repeating the above steps, the automated assembly of the buzzer can be continuously completed.

The left side of the sliding block 2 is fixedly connected to the left side of the inside of the movable frame.

[0012] The above technical solution involves a motor driving a threaded rod to rotate, causing a sliding block two, which is threadedly connected to the threaded rod, to move back and forth within a sliding groove two. This, in turn, drives the moving frame to move back and forth, allowing the position of the moving frame to be adjusted to accommodate assembly tasks at different locations.

[0013] As a further description of the above technical solution:

[0014] The feeding assembly includes a feeding pipe, the bottom of which is fixedly connected to the top front side of the platform. The bottom end of the feeding pipe passes through the platform and is fixedly connected to an air pump II. A material core is fixedly connected inside the feeding pipe, and the output end of the air pump II passes through the bottom of the material core.

[0015] Through the above technical solution, the second air pump conveys materials into the upward material pipe through the material core, realizing the automatic feeding function of the buzzer assembly.

[0016] As a further description of the above technical solution:

[0021] Through the above technical solution, the tooling can slide between the slot and the corresponding baffle to fix and position the buzzer components to be assembled, facilitating the assembly operation.

[0022] As a further description of the above technical solution:

[0023] The support frame has grooves on both the upper and lower sides, and the sliding block two has sliders fixedly connected to the upper and lower sides, with the two sliders slidingly connected to the interior of the corresponding grooves.

[0024] The above technical solution makes the movement of the second sliding block more stable when it moves back and forth, while restricting the direction of movement of the second sliding block.
