Description

Technical Field

[0001] The utility model mainly relates to the field of electronic components, and in particular to a screw machine blanking mechanism. Background Art

[0002] The duplexer is the main accessory of the duplex radio and repeater. Its function is to isolate the transmitting and receiving signals to ensure that both the receiving and transmitting can work normally at the same time. It is composed of two sets of bandpass filters with different frequencies to prevent the local transmitting signal from being transmitted to the receiver. The duplexer is a relatively special two-way three-terminal filter. The duplexer must not only couple the weak receiving signal, but also feed the larger transmitting power to the antenna, and require both to complete their functions without affecting each other. The general duplexer is composed of a spiral resonator cavity. Due to its high operating frequency and the large influence of distributed parameters, it is often made into a sealed sleeve. The general duplexer is composed of six band-stop filters (notch filters), each resonating at the transmitting and receiving frequencies.

[0003] In the invention patent application with application number CN202123060987.0, application publication date 2022.04.26, and titled "A Screw Unloading Mechanism", it includes a unloading channel, a unloading pallet, a unloading frame, a unloading baffle and a driving assembly; the unloading channel is longitudinally arranged and is provided with a discharge port and a feed port, and a first bending portion for buffering is provided at the discharge port. The device arranges a second bending portion at the edge of the receiving portion of the unloading pallet so that small bagged screws can accurately fall to the designated position and carry out subsequent packaging operations together with the switch plate, thereby greatly improving work efficiency.

[0004] However, during the actual process of installing screws on the surface of the duplexer, the feeding mechanism is unable to control the frequency of screw feeding, and since the screws cannot be arranged, the posture adjustment of the screws during feeding takes a long time, which affects the efficiency of screw feeding. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model:

[0006] The utility model provides a screw machine feeding mechanism to solve the problem that the frequency of screw feeding cannot be controlled and the posture adjustment of the screws during feeding needs to be prolonged due to the inability to arrange the screws, thus affecting the efficiency of screw feeding.

[0007] 2. Technical solution:

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is as follows: a screw machine unloading mechanism, including an equipment base, a mounting side plate fixedly connected to one side of the equipment base, an assembly plate fixedly connected to one side of the mounting side plate, a clamping strip movably connected to the upper surface of the assembly plate, a lifting screw gun installed on the top surface of the mounting side plate, a unloading tray arranged on the upper surface of the equipment base, a screw discharging mechanism arranged on one side of the unloading tray on the surface of the equipment base, a special-shaped gear drivingly connected to the lower end surface of the unloading tray,

[0009] The unloading tray includes a fixed base fixed to the surface of the equipment base, a rotating shaft is movably connected to the upper surface of the fixed base, a rotating gear is arranged on the surface of the rotating shaft, a fan panel is fixedly connected to the top surface of the rotating shaft, a screw slot is arranged on one side of the curved surface of the fan panel, a magnetic strip is arranged on the surface of the screw slot, and a torque spring is sleeved and connected between the rotating shaft and the rotating gear on the upper surface of the equipment base.

[0010] The screw discharge mechanism includes an "L"-shaped piece, wherein two "L"-shaped pieces are provided, and a spring side plate is fixedly connected between the "L"-shaped pieces, a propulsion spring is fixedly connected to a surface of one side of the spring side plate, and a screw push plate is fixedly connected to a surface of the other end of the propulsion spring, and sliding grooves are provided on both sides of the screw push plate on the inner surface of the "L"-shaped piece.

[0011] Furthermore, the lower end of the special-shaped gear is connected to a transmission motor on the bottom surface of the equipment base, and the unloading tray forms a rotating structure on the surface of the equipment base through the special-shaped gear.

[0012] Furthermore, the lower end surface of the torque spring is fixedly connected to the surface of the fixed base, and the upper end surface of the torque spring is fixedly connected to the lower end surface of the rotating gear, the rotating shaft is meshed with the special-shaped gear through the rotating gear, and a reciprocating rotating structure is formed by the rotation of the special-shaped gear and the resetting of the torque spring, the fan panel and the screw discharge mechanism are in the same horizontal plane, and the fan panel moves to the upper surface of the assembly plate through rotation.

[0013] Furthermore, the screw push plate forms an elastic structure on the surface of the sliding groove through a push spring, the gap between the "L"-shaped pieces is used for assembling the screw arrangement, and the screws between the "L"-shaped pieces are limited by the curved surface of the fan panel.

[0014] 3. Beneficial effects:

[0015] The utility model has a reasonable design. When the screws are cut and installed on the surface of the duplexer, the screws are placed between the two "L" shaped pieces in the screw discharge mechanism, and the screws between the "L" shaped pieces are used to form an elastic structure between the two "L" shaped pieces through the screw push plate. Under normal working conditions, the screws at one end of the "L" shaped piece are blocked between the "L" shaped pieces through the fan panel. When the screw slot on the surface of the fan panel moves to the open end of the "L" shaped piece, the screws are pushed to the surface of the screw slot under the action of the screw push plate and fixed by the magnetic strip, so as to realize the posture of the fixed screw when cutting, and avoid the situation that the posture adjustment affects the work efficiency.

[0016] When performing the blanking operation, the duplexer is installed on the surface of the clamping bar, and the transmission motor on the bottom surface of the equipment base drives the special-shaped gear to rotate, thereby driving the rotating gear, the rotating shaft and the fan panel to rotate on the surface of the fixed base, so that the screw slot rotates to the surface of the screw discharge mechanism for loading. When the loading is completed, the special-shaped gear continues to rotate, so that the special-shaped gear and the rotating gear are disengaged. Under the action of the torque spring, the fan panel returns to its original position and drives the screw to the top of the assembly plate at the same time. The screw and the duplexer on the surface of the clamping bar are assembled by lifting the screw gun. By controlling the rotation speed of the special-shaped gear, the purpose of controlling the screw blanking frequency can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
