Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat plate, in particular to a VC heat plate edge sealing machine. BACKGROUND

[0002] With the rapid development of mobile phones, VC heat plates are also constantly iterating and upgrading. VC heat plate is a high-efficiency heat dissipation device, mainly used for efficient conduction and uniform distribution of heat. Its working principle is to realize rapid heat conduction by using phase change heat transfer principle.

[0003] The internal of VC heat plate is a vacuum cavity, filled with a small amount of working liquid (such as water or ethanol). When the heat source contacts the VC heat plate, the liquid evaporates under heat, the vapor rapidly diffuses to the low-temperature area and condenses to release heat, and the condensed liquid flows back to the heat source through the capillary structure, forming a cycle.

[0004] Due to the high heat conduction performance, uniform heat distribution, light and thin compactness and other advantages of VC heat plate, it is particularly suitable for heat dissipation solutions of compact electronic devices such as smartphones, notebook computers and high-performance graphics cards, effectively solving the heat dissipation problem of high-power chips.

[0005] Chinese patent with publication number CN102780043B discloses a lever type edge sealing machine, which comprises a machine box, a bottom plate, guide columns, pressure springs, guide sleeves, sliding plates, upper edge sealing heating blocks, lower edge sealing heating blocks, cross beams, fulcrum pieces, levers, output shafts and cylinders. The bottom plate and the cross beam are fixed in the machine box, the fulcrum piece is fixed at the bottom of the cross beam, the lower edge sealing heating block is fixed on the bottom plate, the lower end of the guide column is fixed on the bottom plate, the pressure spring and the guide sleeve are sleeved on the guide column, the sliding plate is fixed on the guide sleeve, and the upper edge sealing heating block is fixed on the sliding plate. The upper edge sealing heating block is located directly above the lower edge sealing heating block; the cylinder is fixed on the bottom plate, the lower end of the output shaft is connected to the cylinder, the middle part of the lever is hinged to the fulcrum piece, one end of the lever is hinged to the upper end of the output shaft, and the other end is located directly above the sliding plate.

[0006] The lever type edge sealing machine has good edge sealing effect and can completely solve the problem of edge sealing slip. However, since it uses a lever to press the heat plate, there is a certain angle between the pressing force and the heat plate, which causes the edge sealing effect of each side of the heat plate to be different, and the edge sealing strength is not enough, which reduces the yield. SUMMARY

[0007] The present application overcomes the shortcomings of the prior art and provides a VC heat plate edge sealing machine.

[0008] In order to solve the above technical problems, the present application provides a VC heat plate edge sealing machine.

[0009] Technical effect: The hydraulic cylinder drives the entire movable sealing plate to descend, thereby making the upper sealing plate and the lower sealing plate fit together to achieve hot-press welding, and finally complete the sealing of the heat spreader. The movement of the entire movable sealing plate can make the upper and lower sealing plates very evenly stressed, reducing uneven stress and avoiding differences in sealing effect on each side, preventing insufficient sealing strength, and greatly improving the yield rate.

[0010] The technical solution further defined in this invention is: a VC heat-sealing plate edge banding machine, comprising a control cabinet, a machine body located next to the control cabinet, and an outer casing of the machine body.

[0011] The sealing platform includes a sealing top plate and a sealing bottom plate, as well as a movable sealing plate that is movably connected between the sealing top plate and the sealing bottom plate;

[0012] The upper and lower sealing plates are located on the bottom surface of the movable sealing plate and the top surface of the sealing base plate, respectively. They are used to secure the upper and lower halves of the VC heat spreader and to achieve hot-press welding of the edges.

[0013] A clamping cylinder is fixed to the top of the movable sealing plate and is used to drive the movable sealing plate to slide. The output shaft of the clamping cylinder is equipped with a push block, and the movable sealing plate is equipped with a push seat that matches the push block at the corresponding position.

[0014] Furthermore, the push block is cylindrical in shape and has a hexagonal prism-shaped limiting block on it; the push base has a recessed hole with the same shape as the push block.

[0015] The aforementioned VC heat exchange plate edge banding machine connects the upper and lower sealing plates via several cylindrical fixed columns, and the movable sealing plate is slidably connected to the fixed columns, with four fixed columns in total.

[0016] The aforementioned VC heat exchange plate edge banding machine has a movable arc plate on its body. The movable arc plate includes two parallel straight edge sections and a semi-circular arc edge section located in the middle. The two straight edge sections are respectively connected to the machine body and the movable sealing plate.

[0017] The aforementioned VC heat exchange plate edge banding machine has a straight edge section that is slidably connected to the machine body in a vertical direction; a straight edge section of the movable guard plate is connected to the movable sealing plate through a horizontally set connecting plate, and the lower sealing plate is fixed to the bottom of the connecting plate.

[0018] The aforementioned VC heat-absorbing plate edge banding machine has a fixed arc plate on its body. One end of the fixed arc plate is fixed to the machine body, and the other end is connected to the sealing base plate.

[0019] The aforementioned VC heat exchange plate edge sealing machine has grooves on both the upper and lower sealing plates that are adapted to the shape of the VC heat exchange plate.

[0020] The beneficial effects of this invention are:

[0021] (1) In the present application, by pressing the output shaft of the oil cylinder, the push block can cooperate with the push seat, thereby driving the movable sealing plate to slide up and down along the fixed column. The upper sealing plate is arranged on the movable sealing plate, and the lower sealing plate is arranged on the sealing bottom plate. The four fixed columns can position the movable sealing plate to slide stably, thereby achieving the effect of stably adhering to the VC heat plate.

[0022] (2) In the present application, the movable arc plate is arranged on the machine body. On the one hand, the movable arc plate can heat the upper sealing plate and the lower sealing plate to realize the heat pressure welding of the two; on the other hand, the movable arc plate has the shape of two vertical sides and a semicircular middle, which can offset the force in other directions and only leave the vertical force, thereby further stabilizing the movable sealing plate and making the movable sealing plate more stable in force during the edge sealing process, and greatly reducing the occurrence of uneven force.

[0023] (3) In the present application, the hydraulic cylinder drives the entire movable sealing plate to descend, so that the upper sealing plate and the lower sealing plate are mutually adhered to realize heat pressure welding, and finally complete the sealing of the heat plate. The entire movable sealing plate moves, which can make the upper and lower sealing plates very uniform in force, reduce the uneven force, thereby avoiding the difference in edge sealing effect, preventing the occurrence of insufficient edge sealing strength, and greatly improving the yield.
