Description

Technical Field

[0001] The present invention relates to the field of communication filter processing equipment, and particularly relates to a multi-station communication filter drilling processing device and a processing method. Background Art

[0002] In the related art, a surface acoustic wave filter is a commonly used radio frequency signal filter for communication terminals such as mobile phones. When a loading signal voltage is applied to the transmitting transducer, an electric field is formed between the input interdigital electrodes, causing the piezoelectric material to generate mechanical vibrations and produce surface waves. The surface waves propagate to both sides and are received by the receiving interdigital electrodes and then converted into electrical signals for output. Since the interdigital electrodes only respond to signals of a specific frequency, a band-pass filter can be formed.

[0003] In the production of communication filters, it is necessary to drill holes in their casings to facilitate subsequent assembly. Therefore, relevant equipment is required for drilling processing. However, there are more than one place on the surface of the communication filter that needs to be drilled. Therefore, during processing, it is necessary to repeatedly rotate it to a suitable position for processing, thus reducing production efficiency. At the same time, the vibrations generated during drilling easily cause the workpiece to shift, and it is difficult to remove the mold that fits too closely to the workpiece, thus prolonging the processing time.

[0004] Therefore, it is necessary to invent a multi-station communication filter drilling processing device and a processing method to solve the above problems. Summary of the Invention

Detailed implementation manners

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] The present invention provides a multi-station communication filter drilling and processing device as shown in Figures 1-6 which includes a workbench 1 and an automatic rotation mechanism 2. The automatic rotation mechanism 2 includes a mounting plate 201 arranged above the workbench 1. Two groups of clamping blocks 202 are arranged inside the mounting plate 201 for installing multiple groups of workpieces to improve efficiency. A turntable 203 is arranged below the mounting plate 201 to provide space for subsequent parts. A chassis 204 is arranged below the turntable 203 and an annular groove is formed on the surface of the chassis 204. The turntable 203 is slidably connected to the annular groove inside the chassis 204, so as to realize the rotation of the turntable 203. A sliding rod 205 is slidably connected inside the chassis 204. The bottom end of the sliding rod 205 is fixedly connected to a stable seat 206. The top end of the stable seat 206 is fixedly connected to a return spring 207 and the opposite top end of the return spring 207 is fixedly connected to the bottom end of the chassis 204. The return spring 207 is sleeved on the outer sidewall of the sliding rod 205. The return spring 207 extends towards both ends in the natural state. The top wall of the turntable 203 is fixedly connected to a rotating cylinder 8. Two groups of inclined grooves 10 are formed on the outer sidewall of the rotating cylinder 8. A guiding fitting block 11 is slidably connected inside the inclined groove 10. The guiding fitting block 11 is fixedly connected to the top end of the sliding rod 205. By using the sliding connection between the guiding fitting block 11 and the inclined groove 10, when the turntable 203 is reset by the return spring 207, the turntable 203 can be rotated by the cooperation of the inclined groove 10 and the guiding fitting block 11, so as to realize the automatic rotation of the workpiece to adjust the punching position, reduce the working procedures and improve the working efficiency.

[0021] As shown in Figures 1-6As shown, a cross groove 13 is formed on the surface of the turntable 203. Above the cross groove 13, there is a cross block 12 which is fixedly connected to the bottom end of the mounting plate 201. A buffer pad 14 is fixedly connected to the bottom end of the cross block 12. Through the cooperation of the cross block 12, the cross groove 13 and the buffer pad 14, the cooperation of the cross groove 13 and the cross block 12 makes the mounting plate 201 more stable when being pressed, prevents it from generating radial displacement, and the buffer pad 14 is used to strengthen the buffering, improving the stability of the structure.

[0022] As Figures 1-6 shown, a top seat 3 is fixedly connected to the top end of the workbench 1. A punching cylinder 4 is fixedly connected to the top end of the top seat 3. The output end of the punching cylinder 4 is fixedly connected with a multi - hole drilling die 401. The punching cylinder 4 is used to drive the multi - hole drilling die 401 to drill holes on the surface of the workpiece. The multi - hole drilling die 401 is located directly above the automatic rotation mechanism 2. Two sets of trigger plates 9 are fixedly connected to the bottom end of the multi - hole drilling die 401. The trigger plate 9 is composed of a telescopic plate fixedly connected to the bottom end of the multi - hole drilling die 401 and a movable spring fixedly connected between the telescopic plates, so as to be linked with other parts. A sliding groove 7 is formed on one side of the workbench 1. A moving box 6 is slidably connected inside the sliding groove 7. The automatic rotation mechanism 2 is installed inside the moving box 6. A servo motor 5 is fixedly connected to one side of the workbench 1. The output end of the servo motor 5 is fixedly connected with a driving gear 15. A driven rack 16 is engaged with the bottom end of the driving gear 15. The driven rack 16 is fixedly connected to one side of the moving box 6. By driving the driving gear 15 with the driven rack 16, the position of the moving box 6 is controlled in cooperation with the driven rack 16, which is convenient for the workers to work.

[0023] As Figures 1-6 shown, a limiting rod 19 is fixedly connected to the bottom wall of the mounting plate 201. A telescopic spring 18 is sleeved on the outer side wall of the limiting rod 19. The telescopic spring 18 extends towards both ends in its natural state. The top end of the telescopic spring 18 is fixedly connected with a linkage block 17 which slides on the outer side wall of the limiting rod 19. One side of the linkage block 17 is fixedly connected with a transmission block 21. Above the transmission block 21, there is an upper guiding block 20, and below the transmission block 21, there is a lower guiding block 22. Both the upper guiding block 20 and the lower guiding block 22 are fixedly connected to one side of the clamping block 202. When the trigger plate 9 is pressed downwards, it drives the linkage block 17 to press downwards, and makes the transmission block 21 press the lower guiding block 22 to move, so that the clamping block 202 clamps the workpiece inward. When the pressure on the trigger plate 9 is released, the linkage block 17 resets under the action of the telescopic spring 18, so that the transmission block 21 drives the upper guiding block 20 to move to both sides, and further makes the clamping block 202 move outwards to reserve space for the workpiece, making it easier for the workers to take out, thus improving the work efficiency.

[0024] As Figures 1-6A multi-station communication filter drilling method is shown, including a multi-station communication filter drilling device as above, and its steps include: S1. Preparation step: Start the servo motor 5 to drive the transmission gear 15 to rotate, so that the moving box 6 slides out of the inside of the workbench 1. Then install the workpiece inside the mounting plate 201, and then reset the moving box 6 through the servo motor 5. S2. Processing step: Start the punching cylinder 4 to drive the multiple drilling dies 401 to descend, and drive the touch plate 9 and the linkage block 17 to descend through the multiple drilling dies 401, so that the clamping block 202 firmly clamps the workpiece and drills holes. Then continue to apply pressure to make the chassis 204 slide down. S3. Rotation step: While the chassis 204 slides down, guide the fitting block 11 to slide down along the inclined groove 10. Then start the punching cylinder 4 to drive the multiple drilling dies 401 to rise, use the elasticity of the return spring 207 to reset the chassis 204, and during the reset process, use the process of the guide fitting block 11 sliding along the inclined groove 10 again to rotate the turntable 203, and make the transmission block 21 reset with the help of the limiting rod 19. Then repeat the S2 step again. S4. Recycling step: Start the servo motor 5 to drive the transmission gear 15 to rotate, so that the moving box 6 slides out of the inside of the workbench 1. Then take out the original workpiece from the clamping block 202 and install a new workpiece, and then reset the moving box 6 through the servo motor 5 and repeat the above operations.
