Referring to fig. 1-3, a clamping tool of an LED lamp sealing machine comprises an air cylinder 1 and a clamping arm frame 2 fixed with an external frame, wherein an output shaft of the air cylinder 1 penetrates through the center of the clamping arm frame 2 and is fixedly connected with a splayed slide block 3, two ends of the clamping arm frame 2 are rotatably connected with two clamping fingers 4, and one end, close to each other, of each clamping finger 4 is bonded with a soft and hollow water bag 5;

the splayed sliding block 3 is formed by combining a cross rod and two inclined rods, each inclined rod is provided with an inclined groove 6, each clamping finger 4 is fixedly connected with a sliding shaft 7, each sliding shaft 7 is clamped in the corresponding inclined groove 6 in a sliding manner, and the synchronous and reverse motion processes of the two clamping fingers 4 are ensured;

the outer wall of the water bag 5 is symmetrically glued and fixed with a plurality of bendable plastic plates 10, an even number of bendable and deformable resistor strips 9 are symmetrically embedded at the upper end of the inner wall of the water bag 5, the water bag 5 is filled with conductive liquid at 60-80 ℃ and does not completely submerge the resistor strips 9, a circle of annular air bag 8 is fixed at the lower side inside the water bag 5, the air bag 8 is communicated with a constant pressure pump 15 through a hose, the constant pressure pump is used for ensuring that the air pressure in the air bag 8 is a stable value, nozzles 11 which are equal to the resistor strips 9 are symmetrically arranged on the side wall of the water bag 5, each nozzle 11 is hermetically communicated with the air bag 8, the straight line where each nozzle 11 is located is not intersected with the axis of the air cylinder 1, the water bag 5 and a lampshade can generate a rotating effect when the nozzles 11 spray gas, and a reset mechanism which is electrically connected with the resistor strips 9 is arranged on each nozzle 11.

The reset mechanism comprises a bulge 12 arranged on the side wall of the spray head 11, a baffle 13 vertical to the axis of the spray head 11 is connected in the bulge 12 in a sliding manner, the baffle 13 and the inner wall of the spray head 11 are fixedly connected with a conductive spring 14 together, one end of a power supply is electrically connected with the top end of the resistor strip 9, the other electrode of the power supply is electrically connected with the spring 14, and the spring 14 is electrically connected with conductive liquid;

the outer wall of the spring 14 is provided with an insulating layer, so that the spring 14 is prevented from contracting to metal contact of adjacent turns to be directly conductive, the constant pressure pump 15 is fixedly arranged on the arm clamping frame 2, the matching part of the output shaft of the air cylinder 1 and the arm clamping frame 2 is of a square rod structure, and the output shaft and the arm clamping frame 2 are in clearance fit, so that the torque applied to the clamping finger 4 when the arm clamping frame 2 rotates is reduced, and the probability of damage of the clamping finger is reduced.

Shower nozzle 11 runs through plastic board 10 and rather than fixed connection, and plastic board 10 has certain hardness, and shower nozzle 11 can avoid its atress and random motion influence rotation effect rather than fixed, and the matrix has been scribbled on resistive bar 9 and has dredged the oil layer, avoids resistive bar 9 to go up the condition emergence that adhesion part conducting solution leads to the access circuit resistance inaccurate.

In the invention, when a lampshade is clamped, the air cylinder 1 is started to push the splayed sliding block 3 to move downwards, in the process, the two sliding shafts 7 slide in the inclined grooves 6 so that the two clamping fingers 4 approach to the middle, so that the water bag 5 clamps and fixes the lampshade, the relative position of each baffle 13 in the spray head 11 is the same in the initial state, at the moment, the constant pressure pump 15 is started to pump air into the air bag 8, and the spray head 11 continuously sprays air outwards as the spray head 11 is communicated with the air bag 8 and the outside;

because the straight line of shower nozzle place in this device is not crossing with the axis of cylinder 1, and the air that shower nozzle 11 spun is not parallel with arbitrary diameter of lamp shade promptly, so the produced reaction force of blowout gas can produce the moment of torsion that makes water bag 5 pivoted, and rotatory process will drive the wick and also follow the rotation, carries out under the circumstances that sintering device does not rotate, can be with the partial sintering of lamp shade 17 and wick contact a whole circle to accomplish the process of sintering and sealing.

In the process, the device rotates around the axis of the output shaft of the cylinder 1 (namely the axis of the lampshade), in the process, the conducting liquid has the effects of concave in the middle and convex on the outer layer under the action of centrifugal force, but the contact positions of the resistor strips 9 and the conducting liquid are the same, namely the current flowing through the springs 14 is the same, so that the gas flow sprayed out of the nozzles 11 is the same, and the rotation of the device can also keep the original position.

If the lampshade is deflected (as shown in fig. 3), at this time, the resistive strips 9 on the side (hereinafter, referred to as the right side, and hereinafter, referred to as fig. 3 as an example) to which the lampshade is inclined are submerged by the conductive liquid to a larger area, whereas the area of the resistive strips on the left side submerged by the conductive liquid is reduced, (the resistance of the resistive strips 9 per unit length is far greater than the conductive liquid, so that the submerged resistive strips are equivalently short-circuited), that is, the resistance of the resistive strip 9 on the left side connected to the circuit is increased, the resistance of the resistive strip 9 on the right side connected to the circuit is reduced, that is, the current connected to the spring 14 on the left side is reduced, the current connected to the spring 14 on the right side is increased and shortened (when the conductive spring is connected with current, each turn of metal generates a same-direction magnetic field, so that the shortened phenomenon occurs, the current is larger, the shortened amount is larger), and the baffle 13 moves to reduce the amount of gas ejected from the corresponding nozzle 11;

therefore, in the state shown in fig. 3, the amount of gas sprayed by the left side nozzle 11 is obviously greater than that of the right side, and the component force of the reaction force generated by the left side nozzle 11 in the diameter direction of the lampshade is obviously greater than that of the right side, so that the lampshade can deflect reversely until the lampshade returns to the vertical state; in the invention, in the rotating process of the lampshade, the submerging degree of each resistor strip 9 is always in a circulating state, and the air injection quantity of each spray nozzle 11 also dynamically changes along with the rotating process, so that the air injection quantity of the side, to which the lampshade tends, can be ensured to be smaller than that of the other side, and the lampshade is always in the effect of recovering towards the vertical direction.

Although the terms of the cylinder 1, the clamping arm frame 2, the splayed slide block 3, the clamping fingers 4, the water bag 5, the inclined groove 6, the slide shaft 7, the air bag 8, the resistance strip 9, the plastic plate 10, the spray head 11, the bulge 12, the baffle 13, the spring 14, the constant pressure pump 15 and the like are used more frequently, the possibility of using other terms is not excluded.
