Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, specifically to a film-applying mechanism for MIC component processing. Background Technology

[0002] MIC components, or microphone components, are commonly used components in communication products. Before processing MIC components, the protective film on the surface needs to be removed and acoustic tests need to be performed. After the tests are completed, the protective film is then reapplied.

[0003] However, existing film application mechanisms suffer from uncontrolled application force. Excessive application force can damage the product, while insufficient application force results in inadequate film adhesion. Furthermore, the film application mechanism needs to rotate a certain angle after picking up the protective film, but existing mechanisms cannot precisely control this rotation angle, leading to misaligned film placement. This results in incomplete application of the protective film, causing dust to adhere to the product surface and affecting product yield. To address these issues, we propose a film application mechanism for MIC component processing. Utility Model Content

[0004] The purpose of this utility model is to provide a film-applying mechanism for MIC component processing, in order to solve the problems mentioned in the background art of existing film-applying mechanisms, such as uncontrolled film-applying force, excessive film-applying force damaging the product, and insufficient film-applying force resulting in insufficient film adhesion; moreover, after the film-applying mechanism picks up the protective film, it needs to rotate at a certain angle, but existing film-applying mechanisms cannot precisely control the rotation angle, resulting in the film-applying position being skewed, causing the protective film to not be fully applied, resulting in dust adhering to the product surface and affecting product yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a film-applying mechanism for MIC component processing, comprising a vacuum film-applying head, a connecting block fixedly mounted on the upper end of the vacuum film-applying head, a connecting rod fixedly mounted on the upper surface of the connecting block, a quick-connect coupling slidably sleeved on the outer surface of the connecting rod, a pressure sensor detachably mounted on the upper end of the quick-connect coupling, a stepper motor mounted on the upper end of the pressure sensor, the bottom of the stepper motor and the top of the pressure sensor fixedly connected, the output end of the stepper motor facing upward and fixedly connected to a quick-connect air tube connector, and a photoelectric sensor fixedly mounted on the stepper motor.

[0006] The film application mechanism is rotatably connected to the external film application equipment. After the vacuum film application head picks up the protective film, it first rotates via a stepper motor. The rotation angle is controlled by a photoelectric sensor. Then, the film is applied. During film application, when the film application mechanism moves downward and contacts the MIC element, it continues to move downward. The pressure sensor monitors the film application force. When the pressure on the pressure sensor reaches a preset value, the film application mechanism is controlled to stop moving downward, thereby controlling the film application force and avoiding affecting the product yield.

[0007] Preferably, a floating spring is movably sleeved on the outer side of the connecting rod, with the top of the floating spring and the bottom of the quick-connect fitting fitting together. When the film-applying head contacts the MIC element and the film-applying mechanism continues to move downward, the quick-connect fitting slides on the outer side of the connecting rod and squeezes the floating spring. After being squeezed, the floating spring transmits its elastic force to the pressure sensor, thereby enabling the pressure sensor to monitor the film-applying force.

[0008] Preferably, the quick-connect coupling has a through-hole on its side, and the connecting rod has a groove on its side corresponding to the position of the through-hole, the groove extending downward.

[0009] Preferably, a limiting pin is detachably installed in the limiting hole. The end of the limiting pin away from the quick-connect coupling passes through the limiting groove and extends into the interior of the connecting rod. The limiting pin and the connecting rod are slidably connected. This slidable connection prevents the connecting rod from detaching from the quick-connect coupling. Simultaneously, when the quick-connect coupling slides outside the connecting rod, the limiting pin guides the connecting rod, preventing it from shifting.

[0010] Preferably, both the quick-connect coupling and the pressure sensor have external threads on opposite sides, allowing for detachable connection via threaded joints. Connecting the quick-connect coupling and pressure sensor via threaded joints facilitates easy disassembly of the quick-connect coupling.

[0011] Preferably, the output end of the stepper motor is fixedly mounted on an adapter, and the end of the adapter away from the stepper motor is fixedly connected to a quick-connect air hose connector. The quick-connect air hose connector is used to fixally connect to an external film-applying device, allowing the film-applying mechanism to be installed on the film-applying device and to perform film-applying operations.

[0012] Preferably, the photoelectric sensor is fixedly installed between the adapter and the quick-connect air hose connector, and a slotted photoelectric switch is provided on the outside of the film-applying mechanism at the position corresponding to the photoelectric sensor. The slotted photoelectric switch is located on the external film-applying equipment. When the stepper motor rotates and the photoelectric sensor scans the slotted photoelectric switch, the slotted photoelectric switch sends a PLC signal, which in turn sends a command to the motor driver, causing the motor driver to control the stepper motor to stop rotating.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0014] This invention features a connecting rod fixedly installed above the vacuum film applicator. A floating spring is fitted over the connecting rod, along with a quick-connect coupling and a pressure sensor. The cooperation of the floating spring, connecting rod, quick-connect coupling, and pressure sensor controls the film applicator force, preventing excessive or insufficient force from affecting product yield. Furthermore, by incorporating a photoelectric sensor and a slotted photoelectric switch on an external device, the rotation angle of the stepper motor driving the film applicator can be precisely controlled through the interaction of the photoelectric sensor and the slotted photoelectric switch, preventing excessive rotation and misalignment of the film applicator.
