As a further improvement of the present invention, before executing step S1, the method further includes step S0: providing a transverse mandrel rack 170, and arranging a plurality of heat pipes inserted with mandrels in the transverse mandrel rack 170; providing a clamping fixture 180, clamping a plurality of heat pipes placed in the horizontal mandrel rack 170 at a time and transferring the heat pipes to the semi-automatic powder filling machine 100;
specifically, in step S0, the heat pipes in the horizontal mandrel holder 170 are clamped and transferred to the tapered grooves or through holes 1315 on the bearing plate 131 of the semi-automatic powder filling machine 100 for fixing the lower ends of the heat pipes.
Specifically, the front clamping plate 151 and the rear clamping plate 152 on the heat pipe fixing mechanism 150 in the step S1 are folded to form a fixing groove 1532 for fixing the upper end portion of the heat pipe.
Specifically, when the front plate 151 and the rear plate 152 of the heat pipe fixing mechanism 150 in step S3 are folded, a V-shaped accommodating space 1542 is formed, and the accommodating space 1542 is filled with the powder.
Specifically, a plurality of heat pipes with inserted mandrels can be placed in the transverse mandrel holder 170 at one time (as shown in fig. 10).
Specifically, the clamping fixture 180 is provided with a clamping portion 181 (as shown in fig. 11), which can clamp all the heat pipes in the horizontal mandrel rack 170 at one time.
Specifically, the clamping fixture 180 is removed before the vibrator 132 is started, so as to reduce the influence of the clamping fixture 180 on the vibration of the heat pipe when the heat pipe is filled with powder.
In the present embodiment, the electric control box 160 sets the vibration time of the vibrator 132. The control switch on the electrical control box 160 is started to start the first cylinder 135, push the heat pipes upwards to a predetermined height, start the second cylinder 156, close the front and rear clamping plates 151 and 152 and fix the heat pipes, and start the vibrator 132 to start the vibration of the bearing plate 131. When the vibrator 132 vibrates, the operator repeats the first half operation of the above step S0. When the vibrator 132 stops vibrating, the piston rod of the second cylinder 156 begins to contract, forcing the front clamping plate 151 to separate from the rear clamping plate 152, causing the front clamping plate 151 to return to the initial position, and the piston rod of the first cylinder 135 begins to contract, forcing the heat pipe carrying mechanism 130 to return to the initial position; at this time, the operator needs to use the clamping jig 180 to clamp and take down the plurality of heat pipes filled with the powder to be placed in the fixed area. Then, the clamping fixture 180 is used to clamp and transfer the heat pipes re-placed in the horizontal mandrel rack 170 to the tapered groove or through hole 1315 of the carrier plate 131, and the steps S2 and S3 are repeated.
In summary, the vibrator 132 is disposed on the supporting plate 131, the structural design between the supporting plate 132 and the two buffering elements 133, and the arrangement between the fixing groove 1532 and the tapered groove or the through hole 1315 and the limiting groove 141, so that the vibrator 132 in the semi-automatic powder filling machine 100 mainly applies work to the supporting plate 131, and the amplitude of the lower end portions of the heat pipes is greater than the amplitude of the upper end portions of the heat pipes. Therefore, the vibration source of the semi-automatic powder filling machine 100 has a "step" type vibration amplitude mode for the heat pipes, which is more beneficial to filling powder and faster in filling rate than the vibration amplitude mode of the traditional automatic powder filling machine.
The invention also discloses a powder filling method of the semi-automatic powder filling machine 100. The advantages of the invention include: the working efficiency is improved, and the labor cost is reduced; noise is reduced, and the working environment is improved; the amplitude mode is changed, so that the heat pipe can be conveniently filled with powder.
