In this embodiment, the feeding channel 12 is provided with a baffle 12a, the pushing device 4 includes a conveyer belt 41 and a pushing cylinder 42, the conveyer belt 41 is located below the baffle 12a, the pushing cylinder 42 is arranged on the left side of the conveyer belt 41 and is fixedly connected with the mounting table 1, and the output end of the pushing cylinder 42 is fixedly connected with a pushing plate 43. The pushing cylinder 42 is used for pushing the filter on the conveying belt 41 onto the feeding plate 13 in the feeding channel 12.

In this embodiment, the mounting table 1 is provided with a longitudinal sliding groove 1b and a transverse sliding groove 1c, and the transverse rack 11 is perpendicular to the longitudinal rack 9. The vertical arrangement ensures that longitudinal movement of the drive beam 7 can drive the transverse clamping block 2 to move transversely.

In this embodiment, 2 sliding columns one 17 are rotatably connected between the longitudinal clamping block 3 and the driving beam 7, and the sliding columns one 17 are slidably connected in the longitudinal sliding grooves 1 b. The bottom of the transverse clamping block 2 is rotatably connected with a sliding column II 15, the sliding column II 15 is connected in the transverse sliding groove 1c in a sliding mode, and the longitudinal rack 9 is connected with the mounting table 1 in a sliding mode through a plurality of L-shaped structures 1d at the bottom of the mounting table 1. The first sliding column 17 and the second sliding column 15 are used for replacing sliding friction by rolling friction, so that the friction resistance in the sliding groove is reduced, and the principle of two-point alignment is utilized except, so that the transverse clamping block and the longitudinal clamping block can keep linear motion.

In this embodiment, the inner sides of the longitudinal clamping blocks 3 and the transverse clamping blocks 2 are provided with rubber pads 16, and the top of the transverse clamping block 2 is provided with a protruding structure 2 a. Rubber pad 16 plays the effect of buffering, protects the wave filter, and protruding structure 2a gives the spacing of a vertical direction of wave filter.

The working principle and the process thereof are as follows:

the filter is conveyed by the conveying belt 41 to the baffle 12a and is blocked by the baffle 12a, the filter is pushed onto the feeding plate 13 in the feeding channel 12 along the baffle 12a by the pushing cylinder 42, the feeding plate 13 is at the bottommost end at the moment, then the piston of the pushing cylinder 42 is retracted, after the main controller receives a signal that the pushing cylinder 42 reaches an initial position, an extending signal is given to the feeding cylinder 14, the piston of the feeding cylinder 14 extends, the feeding plate 13 jacks the filter to the feeding port 1a of the mounting table 1, at the moment, the upper surface of the feeding plate 13 is flush with the upper surface of the mounting table 1, and the feeding cylinder 14 keeps an extending state.

After the main controller receives a signal that the feeding cylinder 14 reaches the highest position, the motor 5 is started, the motor 5 drives the screw rod 8 to rotate, the screw threads matched with the screw rod 8 are arranged on the driving beam 7, the screw rod 8 rotates to drive the driving beam 7 to move towards the direction of the reference block 6, the longitudinal clamping block 3 fixed to the top of the driving beam 7 also moves towards the direction of the reference block 6, when the longitudinal clamping block 3 moves, linear translation is realized through the two sliding rods I, the left-right swinging is avoided, the sliding column I17 is rotatably connected with the driving beam 7 and the longitudinal clamping block 3, and therefore the sliding column I17 can rotate in the longitudinal sliding groove 1b, sliding friction is converted into rolling friction, and friction resistance is reduced.

At this time, the longitudinal rack 9 is fixed with the driving beam 7, so the longitudinal rack 9 also moves in the same direction, the longitudinal rack 9 moves to enable the gear 10 meshed with the longitudinal rack 9 to rotate, the gear 10 is also meshed with the transverse rack 11 above the longitudinal rack 9, the gear 10 rotates to drive the transverse rack 11 to move towards the center, the transverse rack 11 is fixed at the bottom of the transverse clamping block 2, so the transverse clamping block 2 also moves towards the center, and the function of the sliding column two 15 is similar to that of the sliding column one 17, so that the transverse clamping block 2 can realize two-point positioning, and therefore the transverse clamping block can move linearly. An L-shaped structure capable of supporting the longitudinal rack 7 is arranged below the mounting table 1, so that the longitudinal rack 7 does not tend to bend downwards due to gravity.

Horizontal clamp splice 2 draws close to the center with vertical clamp splice 3 simultaneously, then uses benchmark piece 6 to fix to central point and fix as the benchmark automatic positioning, and the restriction of a vertical direction can be given to the casing to protruding structure 2a on the horizontal clamp splice 2, and rubber pad 16 can play the effect of buffering, avoids causing the damage to the casing.

After the positioning and clamping are finished, the motor 5 is closed, the welding machine welds the pcb board and the filter, the welding is finished, the motor 5 rotates reversely, the filter is loosened, the welded product is conveyed to the next procedure by other machines, then the feeding cylinder 14 resets, the main controller receives a reset signal of the feeding cylinder 14, and the pushing cylinder 42 is continuously controlled to push a new filter into the feeding channel, so that the cycle is carried out.

Based on the above: a motor drives the transverse clamping block and the longitudinal clamping block to gather together towards the center to clamp the filter, the situation that multiple actuators work in cooperation to bring is avoided, centering performance is poor, the filter is easy to move, the feeding cylinder is matched with the material pushing cylinder, and the positioning and clamping mechanism is added to realize full-automatic feeding and positioning.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
