Description

Technical Field

[0001] This utility model relates to the field of jigs, and in particular to an auxiliary jig for bending FPC with a vibration motor. Background Technology

[0002] A phone vibration motor is a small electric motor primarily used to generate vibrations in a mobile phone, causing the phone to vibrate when it receives notifications or messages. Its main function is to provide haptic feedback, helping users perceive changes in the phone's status, such as incoming calls, text messages, and WeChat messages.

[0003] A prior art fixture for processing ultra-thin mobile phone vibration motors is disclosed, including a left support, a right support, a fixed plate, a positioning plate, a chuck, and a pressure mechanism. The chuck is located on the side away from the center. Both sides of the fixed plate are provided with stepped holes that communicate with clearance holes. These hydraulic oil holes communicate with T-shaped blind holes respectively. The movable plate has at least two mounting holes on its upper surface. At least two guide posts pass through the mounting holes of the movable plate and are connected at their upper ends to the fixed plate, and at their lower ends to the left base plate of the left support and the right base plate of the right support respectively. A self-locking cylinder is provided on the side surface of the movable plate. The self-locking cylinder is fixedly installed on the outer surface of the connecting block. The piston rod of the self-locking cylinder passes through the connecting block, is located below the movable plate, and is in contact with the outer surface of the guide post. The spring on the piston rod gives the pressure of the chuck at the end of the piston rod a certain degree of toughness, achieving elastic clamping of the material to be processed. However, this fixture has the following drawbacks:

[0004] For example, pressing the guide post with a piston rod can prevent the movable plate from sliding down. However, it has many parts, and the use of a self-locking cylinder results in a high cost of clamping fixtures. Secondly, the single locking structure can cause it to loosen during subsequent use, which will affect the yield of subsequent workpieces.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an auxiliary fixture for bending FPC with a vibration motor. Through the structural design and cooperation between the fixture body, the pressing component, and the driving component, the double limiting cooperation of the abutment part and the lifting part further restricts the movement of the vibration motor in the vertical, horizontal, and longitudinal directions in the mounting position; it prevents the vibration motor from detaching from the mounting position, improves the connection stability between the vibration motor and the mounting position, and its ingenious structural design results in a low fixture cost.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An auxiliary fixture for bending FPC with a vibration motor includes:

[0009] The fixture body has a recessed mounting position at one end for positioning the vibration motor, and a movable groove and a mounting groove are respectively provided on the side of the mounting position; the movable groove is connected to the mounting position.

[0010] The pressing component has an abutting part at one end near the mounting position. The pressing component is movably disposed in the movable groove, so that the abutting part can selectively approach or move away from the wall of the unlocking vibration motor.

[0011] A drive assembly is disposed in a mounting slot. The drive assembly has a raised portion. The drive assembly can move the raised portion to switch between a locked state and an unlocked state. In the locked state, the drive assembly can move the raised portion against the other wall of the vibration motor. In the unlocked state, the drive assembly can move relative to the mounting slot, so that the raised portion moves away from the other wall of the vibration motor.

[0012] As a preferred embodiment, the drive assembly includes a pusher for moving the raised portion, the pusher being movably disposed within a mounting slot.

[0013] As a preferred embodiment, the pusher includes a pressing block and a connecting block. The pressing block extends from one end of the connecting block away from the raised portion and protrudes outside the fixture body. The raised portion extends upward from the other end of the connecting block, protrudes outside the fixture body, and is located beside the mounting position.

[0014] As a preferred embodiment, the drive assembly further includes a first elastic reset member for driving the connecting block to reset, the first elastic reset member being sandwiched between the fixture body and the connecting block.

[0015] As a preferred embodiment, the pressing component includes a mating block for pushing the abutting part to move, the abutting part extending upward from one end of the mating block near the mounting position; the abutting part is exposed outside the fixture body.

[0016] As a preferred embodiment, the pressing assembly further includes a second elastic reset member for driving the mating block to reset, the second elastic reset member being sandwiched between the mating block and the fixture body.

[0017] As a preferred embodiment, the lower end face of the abutment portion is also connected to a limiting block, which moves with the abutment portion.

[0018] As a preferred embodiment, the fixture body includes an upper shell and a lower shell that are assembled together. The mounting position is recessed downward from the upper end face of the upper shell, and the movable groove and the mounting groove are recessed upward from the lower end face of the lower shell, respectively.

[0019] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly relies on the structural design and cooperation between the fixture body, the pressing component, and the driving component. The pressing component has a pressing part at one end near the installation position. The pressing component is movably disposed in the movable groove, allowing the pressing part to selectively approach or move away from the wall of the vibration motor to lock or unlock. In the locked state, the driving component can drive the lifting part to press against the other wall of the vibration motor. Thus, the double limiting cooperation of the pressing part and the lifting part further restricts the movement of the vibration motor in the vertical, horizontal, and longitudinal directions within the installation position, preventing the vibration motor from detaching from the installation position and improving the connection stability between the vibration motor and the installation position. In particular, its structural design is ingenious and the fixture cost is low.

[0020] Secondly, the movable design of the pressing component allows the pressing part to move relative to the mounting position, thus enabling it to meet the pressing and limiting requirements of vibration motors of different specifications, achieving the effect of adapting to multiple specifications of positioning.

[0021] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0039] An auxiliary fixture for bending FPC with a vibration motor includes a fixture body 10, a pressing component 20, and a driving component 30.

[0040] The fixture body 10 has a recessed mounting position 11 at one end for positioning the vibration motor. A movable groove 12 and a mounting groove 13 are also provided on the side of the mounting position 11. The movable groove 12 communicates with the mounting position 11. Preferably, the fixture body 10 includes an upper shell 101 and a lower shell 102 assembled together. The movable groove 12 and the mounting groove 13 are recessed upwards from the lower end face of the lower shell 102. The mounting position 11 is recessed downwards from the upper end face of the upper shell 101. In this embodiment, two sets of the pressing component 20 and the driving component 30 are provided. Correspondingly, two mounting grooves, movable grooves 12, and mounting grooves 13 are each provided. The number of these grooves can be adjusted according to actual needs on the fixture body 10, which will not be elaborated here.

[0041] The pressing component 20 has an abutment portion 21 at one end near the mounting position 11. The pressing component 20 is movably disposed in the movable groove 12, allowing the abutment portion 21 to selectively approach or move away from the wall of the locking or unlocking vibration motor. Preferably, the pressing component 20 includes a mating block 22 for pushing the abutment portion 21, and the abutment portion 21 extends upward from the end of the mating block 22 near the mounting position 11. The abutment portion 21 protrudes outside the fixture body 10. Preferably, the pressing component 20 also includes a second elastic reset member 23 for driving the mating block 22 to reset, and the second elastic reset member 23 is sandwiched between the mating block 22 and the fixture body 10.

[0042] Preferably, the lower end face of the abutment portion 21 is also connected to a limiting block 24. The limiting block 24 moves with the abutment portion 21. The design of the limiting block 24 is such that in the locked state, the limiting block 24 will first abut against the connecting block 34 to provide a stable abutment force to the abutment portion 21.

[0043] The drive assembly 30 is disposed in the mounting groove 13. The drive assembly 30 is provided with a raised part 31. The drive assembly 30 can drive the raised part 31 to move, so as to switch the raised part 31 between a locked state and an unlocked state. In the locked state, the drive assembly 30 can drive the raised part 31 to press against the other wall of the vibration motor. In the unlocked state, the drive assembly 30 can move relative to the mounting groove 13, so that the raised part 31 moves away from the other wall of the vibration motor.

[0044] Preferably, the drive assembly 30 includes a pusher 32 for moving the raised portion 31, the pusher 32 being movably disposed within the mounting groove 13.

[0045] Preferably, the pusher 32 includes a pressing block 33 and a connecting block 34. The pressing block 33 extends from one end of the connecting block 34 away from the raised portion 31 and is exposed outside the fixture body 10. The raised portion 31 extends upward from the other end of the connecting block 34 and is exposed outside the fixture body 10 and located beside the mounting position 11.

[0046] Preferably, the drive assembly 30 further includes a first elastic reset member 35 for driving the connecting block 34 to reset, the first elastic reset member 35 being sandwiched between the fixture body 10 and the connecting block 34.

[0047] The key design feature of this invention lies in the structural design and coordination between the fixture body, the pressing component, and the driving component. The pressing component has a contact part at one end near the mounting position, and is movably positioned in a movable groove. This allows the contact part to selectively approach or move away from the wall of the vibrating motor to lock or unlock it. In the locked state, the driving component can drive the raised part to press against the other wall of the vibrating motor. Thus, the double limiting coordination of the contact part and the raised part further restricts the movement of the vibrating motor in the vertical, horizontal, and longitudinal directions within the mounting position, preventing the vibrating motor from detaching from the mounting position and improving the connection stability between the vibrating motor and the mounting position. In particular, its ingenious structural design results in a low-cost fixture.

[0048] Secondly, the movable design of the pressing component allows the pressing part to move relative to the mounting position, thus enabling it to meet the pressing and limiting requirements of vibration motors of different specifications, achieving the effect of adapting to multiple specifications of positioning.

[0049] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
