Technical Field

[0001] This utility model relates to the field of filter manufacturing technology, and more specifically, to a feeding device for filter assembly. Background Technology

[0002] As one of the core components of a radio frequency (RF) unit, the filter's function is to eliminate interference and clutter, allowing useful signals to pass through with minimal attenuation while attenuating unwanted signals as much as possible. With the development of 5G technology, millions, or even tens of millions, of 5G base stations will be built globally in the future. Currently, 5G base station filters come in three types: small metal cavity filters, plastic filters, and ceramic dielectric filters. In the filter assembly manufacturing process, loading devices are commonly used for automated filter loading.

[0003] For example, a utility model patent with publication number CN210254002U discloses an automatic lead-cutting device for filters used in wireless headphones, including a frame, a feeding assembly, a transferring assembly, and two lead-cutting assemblies. By setting a vibratory feeder in the feeding assembly, manual feeding can be replaced, thereby saving labor costs. By setting a transferring assembly, the filter on the vibratory feeder can be gripped and transported to the lead-cutting assembly for lead cutting. By setting two lead-cutting assemblies, the pins of the filter can be cut.

[0004] In the aforementioned patent, during the assembly of the filter with the corner cut, the material is mainly conveyed in an orderly manner by a vibratory feeder. However, the vibratory feeder currently has poor adjustability of its working height, which increases the difficulty of adjusting the material height of the filter. In addition, the vibratory feeder is inconvenient to move during disassembly and maintenance, which makes operation and maintenance inconvenient. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can address the poor adjustability of the operating height of vibratory feeders and the inconvenience of operation and maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for filter assembly, comprising a support base, a guide assembly on the support base, a support bracket on the guide assembly, a vibratory feeder body on the support bracket, the vibratory feeder body being used to transport the filter to a designated assembly location, a lifting plate on the guide assembly, a lifting mechanism between the lifting plate and the support base, a wheel seat at the bottom of the lifting plate, a shock-absorbing mechanism between the wheel seat and the lifting plate, and a movable wheel at the bottom of the wheel seat.

[0007] In a preferred embodiment, the guiding assembly includes a guide cylinder, which is fixedly connected to the corner of the top of the support base. A guide rod is slidably connected inside the guide cylinder. An expansion groove is formed on the outer surface of the guide cylinder, and a slider is slidably connected inside the expansion groove. One end of the slider is fixedly connected to the guide rod, and the other end of the slider is fixedly connected to the lifting plate.

[0008] In a preferred embodiment, the lifting mechanism includes a self-locking motor, which is fixedly connected to the support base. The output shaft of the self-locking motor is fixedly connected to a bidirectional lead screw, and a pair of threaded seats are threadedly connected to the bidirectional lead screw. A lifting rod is hinged to each threaded seat, and a fixing plate is hinged to the end of the lifting rod facing away from the threaded seat. The fixing plate is fixedly connected to the bottom of the lifting plate.

[0009] In a preferred embodiment, a pair of guide plates are fixedly connected to the top of the support base, and the threaded seat is slidably connected between the pair of guide plates.

[0010] In a preferred embodiment, the damping mechanism includes a damper fixedly connected between the lifting plate and the wheel seat, and a damping spring is provided on the outer side of the damper.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] The feeding device for filter assembly provides lifting power to the lifting plate through the lifting mechanism. The longitudinal movement of the guide rod can adjust the working height of the vibratory feeder body to meet the adjustment requirements of the vibratory feeder body to transport the filter to the specified feeding height. This reduces the difficulty of adjusting the assembly height of the vibratory feeder body.

[0013] The feeding device for filter assembly has casters at the bottom of the lifting plate to control the casters to descend above the support base. This allows the entire feeding device to move by rollers, providing convenience for the transfer and maintenance of the feeding device. In addition, the casters are equipped with shock-absorbing mechanisms, which can absorb and buffer the vibrations and impacts when the feeding device moves. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See also Figures 1-5 This utility model provides a feeding device for filter assembly, including a support base 1, with corner brackets 15 fixedly connected to the periphery of the support base 1.

[0023] There are multiple corner brackets 15, which can be installed in the processing area of ​​the filter assembly process using fasteners.

[0024] In this embodiment: a guide assembly is provided on the support base 1. The guide assembly includes a guide cylinder 2, which is fixedly connected to the corner of the top of the support base 1. A guide rod 3 is slidably connected inside the guide cylinder 2. A support 4 is provided on the guide assembly. A vibrating plate body 5 is provided on the support 4. The vibrating plate body 5 is used to transport the filter to the designated assembly location.

[0025] In this application, four sets of guide components are provided, and the four sets of guide components are respectively arranged at the corners around the support base 1. The guide rod 3 slides in the guide cylinder 2 to provide longitudinal lifting balance support for the support 4, so that the height adjustment of the vibratory feeder body 5 can be more stable. The vibratory feeder body 5 can be installed on the support 4 by fasteners. The working principle of the vibratory feeder body 5 is mainly based on electromagnetic vibration and material spiral track movement. Through vibration, the disordered workpiece is automatically and orderly conveyed. The workpiece is a filter, so the filter can be orderly conveyed toward the processing position of its assembly process. The assembly process may include corner cutting, laser marking and other processing. Since the vibratory feeder body 5 is prior art, it will not be described in detail here.

[0026] In this embodiment: a lifting plate 6 is provided on the guide assembly, and a lifting mechanism is provided between the lifting plate 6 and the support base 1. The lifting mechanism includes a self-locking motor 7, which is fixedly connected to the support base 1. The output shaft of the self-locking motor 7 is fixedly connected to a bidirectional lead screw 8. A pair of threaded seats 9 are threadedly connected to the bidirectional lead screw 8. A lifting rod 10 is hinged to each threaded seat 9. A fixing plate 11 is hinged to one end of the lifting rod 10 facing away from the threaded seat 9. The fixing plate 11 is fixedly connected to the bottom of the lifting plate 6. A telescopic groove 16 is provided on the outer surface of the guide cylinder 2. A slider 17 is slidably connected in the telescopic groove 16. One end of the slider 17 is fixedly connected to the guide rod 3, and the other end of the slider 17 is fixedly connected to the lifting plate 6.

[0027] To ensure the stability of the rotation of the bidirectional lead screw 8, the support base 1 can be equipped with a bearing seat that supports the bidirectional lead screw 8 through rotation. When the lifting mechanism is in use, the self-locking motor 7 is started, which drives the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 can drive a pair of threaded seats 9 to move closer or further apart. In this way, the pair of lifting rods 10 can change the support angle, thereby driving the lifting plate 6 to move up and down. The slider 17 serves to fix the lifting plate 6 and the guide rod 3. In this way, when the lifting plate 6 moves up and down, the slider 17 can drive the guide rod 3 to slide longitudinally in the guide cylinder 2. In this way, the height of the vibratory feeder body 5 based on the support base 3 can be adjusted to meet the height adjustment requirements of the conveying filter at the discharge point of the vibratory feeder body 5.

[0028] The self-locking motor 7 of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, and the power supply is also common knowledge in the art.

[0029] In this embodiment: a pair of guide plates 18 are fixedly connected to the top of the support base 1, and the threaded seat 9 is slidably connected between the pair of guide plates 18.

[0030] The guide plate 18 can linearly constrain the lateral path of the threaded seat 9, thus making the transmission of the threaded seat 9 on the bidirectional lead screw 8 more stable.

[0031] In this embodiment: the bottom of the lifting plate 6 is provided with a wheel seat 12, the bottom of the wheel seat 12 is provided with a movable wheel 13, and the support base 1 is provided with a through groove 19 for the movable wheel 13 to pass through.

[0032] The movable wheels 13 are omnidirectional wheels, and there are four sets of movable wheels 13. When it is necessary to disassemble and transfer the loading device, the fasteners on the corner brackets 15 can be released. Then, the lifting plate 6 is controlled to descend by the lifting mechanism until the movable wheels 13 under the lifting plate 6 pass through the through slot 19 and exceed the position of the support seat 1. The movable wheels 13 can lift the support seat 1. At this time, the movable wheels 13 can provide wheel slip support for the entire loading device so that the loading device can be moved and transferred.

[0033] In this embodiment, a shock-absorbing mechanism is provided between the wheel seat 12 and the lifting plate 6. The shock-absorbing mechanism includes a damper 14, which is fixedly connected between the lifting plate 6 and the wheel seat 12. A shock-absorbing spring 141 is provided on the outer side of the damper 14.

[0034] The number of shock-absorbing mechanisms is the same as the number of moving wheels 13. The two ends of the shock-absorbing spring 141 abut against the opposite surfaces of the lifting plate 6 and the wheel seat 12, respectively. When the feeding device moves by sliding through the moving wheels 13, the shock-absorbing spring 141 can buffer the vibration, and the damper 14 can absorb the vibration energy. In this way, the movement of the feeding device can have the effect of shock absorption and buffering.

[0035] In this embodiment, a pair of slide rods 20 are fixedly connected to the wheel seat 12, and both slide rods 20 are slidably connected to the lifting plate 6.

[0036] The slide bar 20 is a T-shaped structure. By setting a pair of slide bars 20, the wheel seat 12 is provided with longitudinal guidance and balance. When the moving wheel 13 is subjected to lateral force, the wheel seat 12 can prevent deflection. This can prevent the shock absorption mechanism from being torn, thereby improving the reliability of the shock absorption mechanism.
