Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Fig. 1 to 5 schematically show a floating type foam attaching device according to an embodiment of the present invention, which is used for attaching conductive foam 01 to a product blank 00 of a heat dissipation assembly. As shown in the figure, the device includes tool box 10, and the inside of tool box 10 is open-topped cavity 11, and the open-topped top of cavity 11, the top edge of tool box 10 side promptly is provided with step 12, and the one side of keeping away from cavity 11 on the step 12 is higher than the one side that is close to cavity 11.

A movable positioning block 20 is embedded in the cavity 11, and a plurality of symmetrically arranged springs 50 are arranged at the bottom of the positioning block 20. One end of the spring 50 is connected to the lower surface of the positioning block 20, and the other end is connected to the upper surface of the bottom of the jig box 10. The positioning block 20 can move up and down under the elastic force of the spring 50. The springs 50 are symmetrically arranged, so that the stress balance of the positioning block 20 can be ensured, and the positioning block 20 is prevented from shaking all around in the up-down moving process.

The side surface of the positioning block 20 is attached to the inner wall of the jig box 10, and in the process of moving upwards, the top edge of the positioning block 20 is matched with the step 12 at the opening of the cavity 11 to form a groove. The conductive foam 01 can be placed in the groove.

The top of the positioning block 20 is configured with a plurality of supporting sheets 21, and the plurality of supporting sheets 21 are sequentially arranged at a certain interval to form a tooth-shaped structure, and can be matched with the heat dissipation fins arranged in the tooth shape on the heat dissipation assembly.

The bottom of the cavity 11 is symmetrically provided with two vertical guide posts 41, and the bottom of the positioning block 20 is symmetrically provided with two vertical guide grooves 23. One end of the guide post 41 is fixed at the bottom of the jig box 10, and the other end extends vertically upwards in the cavity 11 and is inserted into the guide groove 23. So, locating piece 20 is at the in-process that reciprocates, and guide post 41 and guide way 23 relative motion because guide post 41 and the equal vertical setting of guide way 23 to can ensure that locating piece 20 reciprocates in vertical direction all the time, prevent that locating piece 20 from rocking.

A guide sleeve 42 is arranged at one end of the guide groove 23 close to the bottom of the jig box 10, and the guide column 41 is sleeved in the guide sleeve 42. The bottom of the guide groove 23 is provided with a protrusion 43, the protrusion 43 can be fixed on the upper surface of the bottom of the jig case 10 by bolts, and the top of the guide groove 23 is fitted into the guide groove 23. Therefore, when the positioning block 20 moves up and down, the inner wall of the guide groove 23 rubs against the guide sleeve 42, so that the guide groove 23 can be prevented from wearing the positioning block 20, the uneven stress caused by the deformation of the positioning block 20 is prevented, the movement direction of the positioning block 20 is ensured to be unchanged, and the service life of the positioning block 20 is prolonged.

The central position of locating piece 20 is equipped with the spacing passageway 22 that link up from the front to back, and spacing PIN30 has been alternate in the spacing passageway 22 to the both ends of spacing PIN30 are fixed respectively on two relative lateral walls that set up on tool box 10.

On the jig box 10, two side surfaces opposite to the limit channel 22 are respectively provided with a positioning through hole 13, and the two positioning through holes 13 are arranged opposite to the two tail ends of the limit channel 22. One end of the limiting PIN30 is provided with a flange 31, and the limiting PIN30 penetrates through one positioning through hole 13 of the jig box 10, so that the flange 31 is clamped on the outer side of the jig box 10. The other end of the limit PIN30 passes through the limit passage 22. A bolt penetrates through the other positioning through hole 13 from the jig box body 10, the head of the bolt is clamped on the outer side of the jig box body 10, and the tail of the bolt extends into the cavity 11. The tail of the bolt is in threaded connection with one end, far away from the flange 31, of the limiting PIN30, and the bolt is screwed tightly, so that the limiting PIN30 can be fixed between the two positioning through holes 13.

The diameter of the limiting channel 22 is slightly larger than that of the limiting PIN30, and the positioning block 20 can float up and down by taking the limiting PIN30 as a limit. The difference between the diameter of the limit passageway 22 and the diameter of the limit PIN30 determines the distance the locating block 20 floats up and down. Limit PIN30 prevents locating block 20 from being ejected into cavity 11 by bottom spring 50.

When the jig box body 10 is used, the positioning block 20 is firstly placed into the cavity 11, and the top end of the positioning block 20 is matched with the step 12 at the opening at the top end of the jig box body 10 to form a groove. And placing the conductive foam 01 into the groove, and tearing off the release film on the foam 01.

Then, the product blank 00 of the heat dissipation assembly is placed above the positioning block 20, so that the tooth-shaped structure of the product blank 00 is attached to the support sheet 21 on the positioning block 20 in a staggered manner. The support sheet 21 has a supporting and positioning function for the product blank 00.

After the product blank 00 is properly placed, the product blank 00 is pressed downward to move downward in synchronization with the positioning block 20. In this process, the edge of the product blank 00 is attached to the foam 01 at the edge of the top opening of the cavity 11, and the foam 01 is tightly attached to the product blank 00 during the pressing process. The pressure applied to the product blank 00 is released and the positioning block 20 will float upwards under the action of the bottom spring 50. Therefore, the foam 01 is separated from the constraint of the groove and moves upwards along with the product blank 00, and the foam 01 attaching work is completed.

Adopt the cotton laminating device of floating bubble in this embodiment to carry out the cotton 01 laminating work of bubble, because the cotton 01 of bubble accomplishes positioning work before product stock 00, can prevent the cotton 01 offset of bubble, guarantee the laminating face contact uniformity. In addition, the positions of the foam 01 and the product blank 00 are not required to be manually determined in the attaching process, the precision of attaching the foam 01 can be improved, and the dimensional stability is ensured. Utilize the mode of whole floating resilience to realize the laminating of bubble cotton 01, avoid manual taking or laminating bubble cotton 01, can prevent bad such as bubble cotton 01 fold, deformation, dirty, damage, the floating cotton laminating device laminating efficiency of bubble in this embodiment is high, and the product quality obtains promoting to easy operation is applicable to industrialization, intensive production to manpower demand greatly reduced.
