Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe powder filling, in particular to a heat pipe powder height control jig. Background Art

[0002] A heat pipe is a highly efficient heat conduction device that transfers heat between two ends using the principle of phase change heat transfer. A sintered tube is a type of heat pipe that is made by sintering copper powder at high temperatures. A thin steel roller is inserted into the heat pipe, and then copper powder is filled into the heat pipe. To improve the quality of the sintered tube, the heat pipe must be vibrated after the copper powder is filled into the heat pipe. This vibration reduces the gaps between the copper powder inside the heat pipe, reducing the volume of the powder inside the heat pipe and making the copper powder more compact inside the heat pipe. The heat pipe is then taken to a sintering furnace for sintering. After sintering is complete, the steel roller is removed.

[0003] Existing heat pipe powder filling devices often rely on manual control to open and close the powder outlet. This manual control often suffers from a long response time. Operators must observe, judge, and manually execute actions, resulting in a time lag between decision-making and actual operation. This time lag can lead to inconsistent powder filling amounts on high-speed or continuous production lines, making it difficult for the actual filling amount to accurately match the expected value. Furthermore, repeated operations over long periods of time can cause operator fatigue, and response time increases as fatigue accumulates, further affecting the control accuracy of powder output.

[0004] In view of this, in order to overcome the above technical problems, the present invention proposes a heat pipe powder height control jig to solve the above technical problems. Utility Model Content

[0029] A fixing unit is provided at the upper end of the rotating platform 11 with a slot 112 ; the fixing unit is installed at the lower end of the rotating platform 11 ; the fixing unit is used to fix the heat pipe inserted into the slot 112 .

[0030] As an embodiment of the present invention, two baffles 23 and two powder control plates 221 are provided; a straight plate 25 is fixedly connected to one side of the powder control plate 221 away from the pneumatic push rod 224; and the two powder control plates 221 are fixedly connected by a connecting plate 251.

[0031] As an embodiment of the present utility model, a mounting plate 252 is provided between the powder control plate 221 close to the pneumatic push rod 224 and the pneumatic push rod 224; the mounting plate 252 is fixedly connected to the powder control plate 221; a sealing groove 253 is provided on the side wall of the mounting frame 2; the end of the mounting plate 252 away from the powder control plate 221 is slidably sealed in the sealing groove 253.

[0032] As an embodiment of the present invention, a groove 231 is provided at the lower end of the baffle 23; a slide plate 232 is slidingly and sealingly connected in the groove 231; the slide plate 232 is connected to the bottom of the groove 231 by a fixed spring 233; the slide plate 232 is made of PTFE material.

[0033] As an embodiment of the present utility model, the fixing unit includes a clamping block 13; a strip groove 14 is opened at the lower end of the rotating table 11; the clamping block 13 is slidingly and sealingly connected in the strip groove 14; a connecting spring 15 is provided in the strip groove 14; one end of the connecting spring 15 is fixedly connected to the clamping block 13; and the other end is fixedly connected to the groove wall of the strip groove 14; the number of the clamping blocks 13 is set to two; the two clamping blocks 13 are distributed on both sides of the slot 112.

[0034] As an embodiment of the present invention, a V-shaped groove 131 is provided on a side where the two clamping blocks 13 are close to each other; and a chamfer is provided on the upper end surface of the clamping block 13;

[0035] During operation, existing heat pipe powder filling devices often rely on manual control of the opening and closing of the powder outlet 24. Manual control of the opening and closing of the powder filling port often has a long response time problem. That is, the operator needs to observe, judge, and manually perform the action, resulting in a time lag between the decision and the actual operation. This time lag can lead to inconsistent powder filling amounts on high-speed or continuous production lines, making it difficult for the actual powder filling amount to accurately match the expected value. In addition, repeated operations over a long period of time can cause operator fatigue, and the response time will also increase as fatigue accumulates, which will further affect the control accuracy of the powder discharge amount.

[0036] To this end, the present invention sets a powder control plate 221 so that the diameter of the through groove 225 provided at the lower end of the powder control plate 221 is fixed. When the copper powder in the hopper 21 enters the feeding chamber 222, the copper powder will fall into the through groove 225, so that the powder control plate 221 drives the copper powder filled in the through groove 225 to the powder outlet 24, so that the copper powder in the through groove 225 can enter the powder discharge pipe through the powder outlet 24, and then be introduced into the heat pipe by the powder discharge pipe, thereby avoiding the influence of the operation reaction time on the control accuracy of the powder output amount; thereby ensuring that the actual powder filling amount each time can accurately match the expected value, so that the practical application effect of the present invention is effectively improved;

[0037] The heat pipe is then inserted into the slot 112 of the rotating table 11. In the initial state, the user inserts the heat pipe into the slot 112 at the upper end of the rotating table 11, so that during the process of inserting the heat pipe into the slot 112, the heat pipe will contact the upper end surface of the clamping block 13. Since the upper end surface of the clamping block 13 is provided with an arc chamfer, the heat pipe will push the two clamping blocks 13 to squeeze the fixing spring 233 in the strip groove 14 to move in the direction of moving away from each other, so that the clamping blocks 13 are separated from each other so that the heat pipe is inserted between the two clamping blocks 13. Since the clamping blocks 13 are pushed by the restoring force of the fixing spring 233, the two clamping blocks 13 can produce an extrusion and clamping effect on the heat pipe under the push of the restoring force of the fixing spring 233, thereby making the heat pipe inserted into the slot 112 clamped in the slot 112 by the clamping block 13; thereby ensuring that the heat pipe can be stably filled with powder in the slot 112, and the V-shaped groove 131 is provided on the side where the clamping blocks 13 are close to each other, so as to increase the roughness of the surface of the clamping block 13. The friction between the clamping block 13 and the heat pipe is increased, thereby improving the clamping effect of the clamping block 13 on the heat pipe; when the clamping block 13 clamps the heat pipe, the user controls the driving motor 12 to operate, so that the driving motor 12 drives the gear ring 111 to rotate through the driving gear 121, so that the gear ring 111 drives the rotating table 11 fixed thereto to rotate until the upper end of the heat pipe is aligned with the end of the powder discharge pipe away from the powder discharge port 24; at this time, the user controls the lower end of the hopper 21 to open, so that the copper powder in the hopper 21 enters the feeding chamber 222, so that the copper powder entering the feeding chamber 222 falls to the upper end of the powder control plate 221, because the upper end of the powder control plate 221 is provided with a through groove 225; the copper powder falling to the upper end of the powder control plate 221 will fall into the through groove 225 until the through groove 225 is filled with copper powder, and at this time the pneumatic push rod 224 is controlled to operate, so that the pneumatic push rod 224 can push the mounting plate 252 to move in the direction away from the sealing groove 253;The mounting plate 252 drives the powder control plate 221 connected thereto to move toward the direction close to the baffle 23. Since, in the initial state, the two powder control plates 221 are connected by the connecting plate 251, and the baffle 23 is in sliding and sealing contact with the upper end surface of the powder control plate 221, when the mounting plate 252 drives the powder control plate 221 connected thereto to move, the powder control plate 221 will push the other powder control plate 221 to move synchronously through the connecting plate 251, so that both powder control plates 221 are in sliding and sealing contact with the baffle 23, so that the powder control plates The excess copper powder on the surface of 221 is blocked by the baffle 23 and scraped off from the upper end of the powder control plate 221, so that the excess copper powder on the upper end of the powder control plate 221 can be kept in the feeding chamber 222, so that the copper powder on the two powder control plates 221 is scraped off to the upper ends of the connecting plate 251 and the mounting plate 252 respectively. When the powder control plate 221 passes over the baffle 23, the powder control plate 221 drives the copper powder in the through groove 225 to pass over the baffle 23 to the discharge chamber 223 until the through groove 225 is aligned with the powder outlet 24, so that the copper powder in the through groove 225 is The filled copper powder falls into the powder discharge pipe through the powder outlet 24, and is finally introduced into the heat pipe by the end of the powder discharge pipe facing the heat pipe, so that the discharged volume of the copper powder is the volume of the through groove 225, thereby ensuring that the actual powder filling amount each time can accurately match the expected value; when the pneumatic push rod 224 contracts, the pneumatic push rod 224 can pull the mounting plate 252 to drive the two powder control plates 221 to cross the baffle 23 and return to the feeding chamber 222 again; at this time, the mounting plate 252 enters the sealing groove 253, so that the copper powder on the mounting plate 252 is sealed. The copper powder is blocked by the upper end wall of the slot 253 and moves toward the powder control plate 221, so that it is once again caught on the powder control plate 221. Similarly, the copper powder on the connecting plate 251 is blocked by the baffle 23 near the sealing slot 253 and is scraped to the powder control plate 221 away from the sealing slot 253. The copper powder accumulated on the powder control plate 221 can fall into the through groove 225 of the powder control plate 221, thereby reducing the waste of copper powder and improving the utilization rate of copper powder. This further enhances the practical application effect of the present invention.
