Description

Technical Field

[0001] The invention relates to the technical field of silver removal of dielectric filters, in particular to a laser tuner of a dielectric filter and an automatic parallel silver removal method thereof. Background Art

[0002] In the production process of dielectric filters, the silver layer in multiple resonant holes on the dielectric filter cavity is adjusted to adjust the state in the resonant holes and the coupling relationship between the resonant holes, so that the dielectric filter can output according to the designed waveform. Dielectric filters are usually composed of multiple resonant holes, so it is necessary to adjust the silver layer in several to dozens of resonant holes.

[0003] At present, the common practice for adjusting the resonant hole in the industry is to first fix the dielectric filter on the debugging platform, read the real-time monitoring performance of the dielectric filter through the network analyzer and transmit it to the computer, the computer compares the received monitoring performance with the target performance, analyzes the data through the debugging algorithm software, generates a control signal, and then drives the removal device to locate at the position of the corresponding resonant hole, and then quantitatively removes the silver layer on the surface of the resonant hole according to the silver layer removal amount set by the control signal until the real-time monitoring performance matches the target performance. This approach has the following shortcomings:

[0004] 1) The removal device for quantitatively removing the silver layer generally adopts mechanical grinding, which is essentially to control the grinding head to move back and forth through a servo drive device to achieve the removal of the silver layer. The operation is inconvenient, cumbersome and complicated, and the grinding is unstable, the precision is not high, the cost is high, and the efficiency is low;

[0005] 2) A serial adjustment method is adopted, and a single channel of a vector network analyzer can only adjust one dielectric filter at a time. That is, when the removal device removes the silver layer on the surface of one of the resonant holes, the network analyzer is in an idle state. Only after one adjustment is completely completed can the next one be started, resulting in low work efficiency, high energy consumption and high cost. Summary of the invention

[0082] The working process of the material conveying device 1 is:

[0083] 1) First, manually place the materials in a plurality of trays, and stack the plurality of trays on one end of the top of the loading conveyor rack 111;

[0084] 2) The first lifting module 114 of the loading conveyor mechanism 11 lifts a number of trays on the second to last layer on the loading conveyor rack 111, and then the first translation module 112 drives the first pushing module 113 to push the trays on the bottom layer to the other end of the top of the loading conveyor rack 111 (i.e., the loading position);

[0085] 3) The first transfer mechanism 2 transfers the material in the tray to the first positioning platform 8 for positioning, and then transfers it to the clamp mechanism 3;

[0086] 4) After the material in the tray is transferred, the second transfer mechanism 13 transfers the empty tray to the unloading conveyor mechanism 12 for unloading, and then circulates in sequence. The first translation module 112 drives the first pushing module 113 to push the tray at the bottom layer to the other end of the top of the loading conveyor frame 111, thereby realizing uninterrupted loading.

[0087] After the material tray at one end of the top of the unloading conveyor rack is filled with qualified materials except silver (transferred by the first transfer mechanism 2), the unloading conveyor mechanism 12 transfers the material tray to the other end of the top of the unloading conveyor rack to complete the unloading.

[0088] In addition, in this embodiment, a spare platform 9 is provided on one side of the unloading conveying mechanism 12, and a number of empty trays are placed on the spare platform 9. When the trays are insufficient, the second transfer mechanism 13 can transfer the empty trays on the spare platform 9 to the unloading conveying mechanism 12 for emergency use.

[0089] Fixture mechanism 3: Figure 5 As shown, in this embodiment, two clamp transfer modules are provided, and the two clamp transfer modules are arranged in parallel and spaced apart from each other. Two limit grooves are provided on the clamp body 33 of each clamp transfer module, so that the synchronous transfer of four materials can be realized, and the working efficiency is high; the third translation module 31 of each clamp transfer module includes a synchronous belt assembly, and a first motor for driving the synchronous belt assembly to operate; the first sliding seat 32 is connected to the synchronous belt assembly, and the first motor can drive the first sliding seat 32 to move back and forth through the synchronous belt assembly; the pressure plate module 34 of each clamp transfer module includes a first support arranged on one side of the synchronous belt assembly, and a third lifting air module arranged on one side of the first support in the vertical direction. Cylinder, and a first pressure plate driven and connected to the third lifting cylinder, two pressure grooves are arranged at intervals in the length direction on the top of each first pressure plate, which are used to limit and fix the material on the fixture body 33; when working, the first transfer mechanism 2 first transfers the material from the feeding conveying mechanism 11 to the first positioning platform 8 for preliminary positioning, and then the first transfer mechanism 2 transfers it to the limiting groove on the fixture body 33; then, the third translation module 31 drives the fixture body 33 to transfer the material to the bottom of the pressure plate module 34 via the first sliding seat 32; then, the third lifting cylinder drives the first pressure plate to descend to limit and fix the material, thereby facilitating the laser silver removal mechanism 4 to remove silver from the material.

[0090] The first transfer mechanism 2 and the laser silver removal mechanism 4: The mechanical arm module 21 of the first transfer mechanism 2 is controlled by the background, and can drive the second suction cup module 22 to move in all directions, so as to facilitate the transfer of materials; the rotating module 41 of the laser silver removal mechanism 4 can drive the laser head module 42 to rotate, so as to facilitate the laser head module 42 to remove silver from the material (the laser head module 42 can realize lifting movement); during specific operation, the first transfer mechanism 2 first transfers the material from the loading conveying mechanism 11 to the first positioning platform 8 for initial positioning, and then transfers the material to the clamping mechanism 3; after the material is desilvered, the first transfer mechanism 2 transfers the material with qualified silver removal to the material tray on the unloading conveying mechanism 12, and directly transfers the material with unqualified silver removal to the defective product recovery box 6, so as to realize the automatic sorting of qualified materials and unqualified materials and save labor costs.

[0091] At the same time, the present invention also provides an automatic parallel silver removal method for dielectric filters, which can be used to simultaneously complete the adjustment of two or more materials (dielectric filters). During the entire test process, the materials respond and perform adjustments alternately according to instructions, which greatly improves work efficiency; specifically,

[0092] First, a hardware path between the network analyzer 5 and one of the materials is established through the radio frequency switch. The network analyzer 5 reads the S parameters of the material and transmits them to the background. The background simulates the S parameters through the simulation algorithm, and calculates the difference between the simulated material model and the preset target value (preset according to actual requirements). Then, the removal amount is set, and the laser silver removal mechanism 4 is controlled to remove silver from the material according to the set removal amount. After the network analyzer 5 reads the S parameters of the material and transmits them to the background, the background will control the network analyzer 5 to immediately establish a hardware path with another material through the radio frequency switch (so that the network analyzer 5 is not in an idle state), and control the network analyzer 5 to read the S parameters of the material and transmit them to the background. After the background calculates the difference between the S parameter of the previous material and the preset target value, it controls the laser silver removal mechanism 4 to remove silver from the previous material, and at the same time, calculates the difference between the S parameter of the material obtained at this time and the preset target value, and cycles in sequence, thereby establishing multiple hardware paths, and then realizing the parallel and time-sharing silver removal of multiple materials by the laser silver removal mechanism 4, thereby improving work efficiency; in addition, the network analyzer 5 will also review the materials from which silver has been quantitatively removed, repeat the above steps, and form a closed process loop; this method can make each mechanism in a state of full utilization, high work efficiency, and can be applied to the silver removal of any type of dielectric filter, and has stronger consistency and stability than the existing serial method.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
