Automatic assembly equipment for heat pipes and cooling fins

technical field

The invention provides an automatic assembly equipment for heat pipes and heat dissipation fins, which is composed of a continuous stamping die device and two sets of transmission mechanisms of the upper and lower groups, and the heat dissipation fins punched in the continuous stamping die are used to The upper transmission mechanism in the mold makes the punch produce an automatically decreasing step stroke, so that the heat dissipation fins are tightly inserted into the heat pipe one by one from bottom to top, and the assembly is completed quickly.

Background technique

The traditional heat sink module composed of heat pipes consists of a plurality of heat dissipation fins (aluminum or copper), one or more heat pipes and a base (commonly known as a copper base). A fan lock frame can be combined as needed to lock and fix a heat dissipation fan; the known assembly method of heat dissipation fins and heat pipes is to fix the heat pipes to the upper die of the stamping die with a clamp in advance, and use a punching machine The stamping assembly is completed, but after the completion, the punching machine must be shut down first, and then the upper mold clamping tool must be taken out and replaced by manual operation, so the production speed is inevitably stagnant and slow, and the manual replacement operation is prone to negligence, resulting in deformation of the heat pipe. The defective rate rises, so with the known assembly method, it is difficult to achieve a complete tight match between the through holes of the heat dissipation fins and the heat pipe, the assembly is complicated and inconvenient, the production efficiency is poor, and the assembly cost is also high, and the defective rate is even higher, which is also The heat conduction efficiency of the heat dissipation fins and heat pipes will be reduced due to poor contact bonding.

Detailed ways

As shown in Figures 1 to 4, the automatic assembly equipment for heat pipes and cooling fins of the present invention is mainly composed of a continuous stamping die device 3 and two sets of transmission mechanisms 41, 42, wherein:

The continuous punching device 3 is composed of an upper die 31, a lower die 32 and a punch 33 disposed in the upper die 31, and the material 2a for the cooling fins including the strip 21 is selected for cooperation with an automatic feeding device (not shown). , gradually make the semi-finished product 2b of the cooling fin to the finished product 2 (as shown in Figure 5) through the segmental stamping process, and deliver the finished product 2 of the cooling fin to the working position above the workbench 421 of the lower transmission mechanism 42 (such as As shown in Figure 6), the finished product 2 of the cooling fins has been fully formed at this time, and it is punched with one or more than one through holes 22 that can be closely matched with the heat pipe 1, for supplying one or more than one heat pipes. Catheter 1 is on standby for combination;

The upper transmission mechanism 41, as shown in Figure 4, is located in the upper die 31 of the continuous stamping die device 3, utilizes a motor 411 to drive the screw rod 412, so that the moving block 413 on the screw rod 412 can move in a linear fixed frame, so that the moving block The punch 33 contacted by 413 can therefore produce a fixed degressive stroke (the moving block 413 and the inclined surface block 331 at the head end of the punch 33 are in the relative contact state of most step slopes 414 and 332, and the moving block 413 moves backward. One grid, the punch 33 will decrease by a fixed displacement), so that the punch 33 will automatically decrease by a fixed displacement at each stamping interval, so that a plurality of fin products 2 can be stamped layer by layer with the same spacing in sequence Implanting one or more heat pipes 1;

The lower transmission mechanism 42 mainly includes a workbench 421 and a clamping fixture 422, and the clamping fixture 422 is used to temporarily fix one or more heat pipes 1 (referred to as components to be processed, which can also be included together with A base 5), so that the finished product 2 of the heat dissipation fin is stamped with the punch 33, and the finished product 2 of the heat dissipation fin is accurately implanted into the heat pipe 1 (as shown in Figure 7). After the punch 33 is pulled away, it is waiting for the next heat dissipation The fin finished product 2 then enters the upper working position of the workbench 421 (as shown in FIG. 8 ) to repeat the stamping action. Matching, so after inserting, an excellent tight positioning is formed, and the punch 33 in the upper die 31 cooperates with the automatic decrementing stroke of the upper transmission mechanism 41 to move the plurality of fin products 2 one by one. The layer rushes into the heat pipe 1, and when the cooling fins 2 are filled (as shown in Figure 9), the detection device (not shown) is used to control the workbench 421 to automatically withdraw, and the next group of components to be processed will be sent into place (as Fig. 10), for repeating above-mentioned stamping process;

Utilizing the above-mentioned continuous stamping die device 3 and the upper and lower transmission mechanisms 41, 42 in conjunction with the use, the assembly work of the heat pipe 1 and the heat dissipation fin 2 forms a consistent and rapid production, so it is very suitable for mass production, especially the heat dissipation fin 2 After being stamped and inserted into the heat pipe 1, it immediately forms a tight positioning, so the bonding contact is extremely tight and strong (as shown in Figure 11), and there is no need to use solder paste or other adhesives for media bonding, so the overall assembly can be simplified and the production efficiency can be greatly improved. , reduce the assembly cost, and the through hole 22 of the heat dissipation fin 2 and the heat pipe 1 are nested and tightly matched, so the defective rate is low, and continuous and rapid production is possible, and the heat conduction between the heat dissipation fin 2 and the heat pipe 1 is ensured Efficiency remains at its best.

The finished product 2 of heat dissipation fins punched by the above-mentioned continuous stamping die device 3 has a through hole 22 and a ring wall 221 with the same spacing as the above, and its two sides can also be formed with a straight wing with the same spacing. Sheets 222, so each cooling fin 2 forms a close adjacent stack with the same pitch, and is arranged in a block shape.

The above-mentioned one or more heat pipes 1 can also be clamped and combined with a base 5 (copper base) in advance, and at the same time, use the lower transmission mechanism 42 to send them into the lower die 31 of the continuous stamping die device 3, so that through continuous stamping The heat dissipation fins 2 punched by the mold device 3 can use the upper transmission mechanism 31 to drive the punch 33, and are closely matched and fitted on the heat pipe 1 and the base 5 with a decreasing stroke, so that a set including the heat dissipation fins 2, The radiator module of the heat pipe 1 and the base 5. (Figure 12).

Similarly, as shown in FIG. 13, the one or more heat pipes 1 can temporarily clamp a base 5a (copper base) with a clamping tool 422, and send it into the mold by using the lower transmission mechanism 42. Moreover, a matching structure of mutual concave and convex is provided in advance at the junction of the base 5a and the heat dissipation fins 2, so that the heat dissipation fins 2 punched through the continuous stamping die 3 can not only closely match the fins to the heat pipe one by one 1, and at the same time form a variety of shape-matching clamping combinations or hook positioning with the base 5a, so as to quickly and tightly combine into a radiator module including the base 5a.

To sum up, the automatic assembly equipment for heat pipes and heat dissipation fins of the present invention can effectively simplify manufacturing, improve production efficiency, and reduce assembly costs. The heat transfer efficiency is the best.
