Description

Technical Field

[0001] The present invention relates to a hot pressing fixture for a computer housing, and more particularly to a fixture for controlling the step difference in the hot pressing bonding of a computer housing. Background Art

[0002] At present, after the components in the 3C industry are assembled, the flatness, deformation, gap, step difference, etc. of the product cannot reach the tolerance control range designed for the product. After the hot pressing bonding of the existing computer housing D-piece product, the step difference between the aluminum and plastic parts cannot exceed the controlled tolerance. Due to the large size of the product, the outer shape tolerance of the aluminum part is ±0.15. For the plastic part product size, the conventional shaping fixture cannot shape the oversized size within the control range, which easily leads to unstable step difference between the aluminum and plastic parts of the product. Therefore, a fixture for controlling the step difference in the hot pressing bonding of a computer housing is specially developed. Summary of the Invention

[0003] The main purpose of the present disclosure is to provide a fixture for controlling the step difference in the hot pressing bonding of a computer housing, which is used to solve problems such as the flatness, deformation, gap, step difference, etc. of the product not being able to reach the tolerance control range designed for the product.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A fixture for controlling the step difference in the hot pressing bonding of a computer housing includes an upper template bottom module, a bottom die fixing plate, and a bottom die heating and cooling dual-purpose plate. The bottom module is divided into a top side of the bottom module, a bottom side of the bottom module, a right side of the bottom module, and a left side of the bottom module. The bottom die fixing plate is installed on the bottom side of the bottom module. A mold closing pin is fixedly installed on the bottom die fixing plate, and a guide sleeve is sleeved on the mold closing pin. The upper template passes through the mold closing pin. A heat-conducting silica gel is fixedly connected to the bottom of the upper template. A bottom die heating and cooling dual-purpose plate is fixedly installed at the bottom of the bottom die fixing plate, and a mold foot is fixedly connected to the bottom of the bottom die heating and cooling dual-purpose plate. Side pushing mechanisms are provided on both sides of the bottom die fixing plate.

[0006] Preferably, a plurality of limit columns are threadedly connected to the bottom of the upper template, and the limit columns are movably installed on the bottom die fixing plate.

[0007] Preferably, aluminum part positioning posts a, b, c, and d are installed on the top side of the bottom module, and the four aluminum part positioning posts are distributed in a rectangular array.

[0008] Preferably, an aluminum part main body is installed above the top side of the bottom module, and a plastic part is provided on the side surface of the aluminum part main body.

[0009] Preferably, a top material structure plate is fixedly installed below the bottom die heating and cooling dual-purpose plate, and a plurality of top material cylinders are installed on the top material structure plate. The output end of the top material cylinder is connected to the bottom side of the bottom module.

[0010] Preferably, a plurality of evenly distributed suction cups are fixedly connected to the bottom of the upper template.

[0011] Preferably, the side pushing mechanism includes a linear slide rail, a side pushing cylinder, a left cylinder push block, a right cylinder push block, a linear bearing, and an equal-height guiding screw. Linear guide rails are fixedly installed on both sides of the bottom die fixing plate through equal-height guiding screws. A left cylinder push block and a right cylinder push block are respectively movably installed on the two linear guide rails, and linear bearings are installed on both cylinder push blocks. A left push block is fixedly connected to the linear bearing on the left cylinder push block, and a right push block is fixedly installed on the linear bearing on the right cylinder push block.

Side push mechanisms are provided on both sides of the bottom die fixing plate 11.

[0029] Specifically, a number of limit posts 3 are threadedly connected to the bottom of the upper template 1, and the limit posts 3 are movably installed on the bottom die fixing plate 11.

[0030] Specifically, an aluminum part positioning post a9-1, an aluminum part positioning post b9-2, an aluminum part positioning post c9-3, and an aluminum part positioning post d9-4 are installed on the bottom module top side 10-1, and the four aluminum part positioning posts are distributed in a rectangular array.

[0031] Specifically, an aluminum part main body 22 is installed above the bottom module top side 10-1, and a plastic part 22 is provided on the side surface of the aluminum part main body 22.

[0032] Specifically, a top material structure plate 14 is fixedly installed below the bottom die heating and cooling dual-purpose plate 12, and a number of top material cylinders 15 are installed on the top material structure plate 14. The output end of the top material cylinder 15 is connected to the bottom module bottom side 10-2.

[0033] Specifically, a number of evenly distributed suction cups 18 are fixedly connected to the bottom of the upper template 1, and the suction cups 18 are vacuum suction cups.

[0034] Specifically, the side push mechanism includes a linear slide rail 16, a side push cylinder 21, a left cylinder push block 5-1, a right cylinder push block 5-2, a linear bearing 6, and an equal height guiding screw 8. Linear slide rails 16 are fixedly installed on both sides of the bottom die fixing plate 11 through equal height guiding screws 8. A left cylinder push block 5-1 and a right cylinder push block 5-2 are respectively movably installed on the two linear slide rails 16, and linear bearings 6 are installed on both cylinder push blocks.

[0036] Specifically, a floating spring column 17 is fixedly connected to the side surface of the bottom module, and a floating spring is sleeved on the floating spring column 17.

[0037] The specific implementation of this embodiment is as follows: First, place the plastic part 22 product on the bottom plate of the hot pressing fixture, then place the aluminum part product with glue dots on top of the plastic part. The aluminum part manipulator automatically grabs and places it into the fixture, and the vacuum adsorption of the fixture fixes the aluminum part. The two side cylinders automatically push the plastic part to control the step difference between the aluminum part 23 and the plastic part 22. The hot pressing machine table drives the upper mold of the fixture to press down for heating. When the time is up, the hot pressing machine table rises, and the product after hot pressing bonding is taken out. After hot pressing bonding, the flatness, deformation, gap, step difference and other bad factors of the product are controlled, improving the yield and efficiency.

[0038] The bottom mold of the fixture is designed to be split according to the quantity and shape of the plastic part 22, which is convenient for size control. The bottom mold of the fixture is increased with a vacuum chuck 18 to suck the aluminum part product to prevent the aluminum part from deforming during the heating process and affecting the product control size. When sucking the aluminum part product, the side pushes the plastic part 22 for limit control to control the step difference between the aluminum part 23 and the plastic part 22.

[0039] The left and right plastic part positioning bottom modules adopt a sliding mechanism. The side surface of the positioning bottom module is increased with floating springs. When the aluminum part 23 is placed down, it will not touch the paint on the appearance of the left and right plastic parts, avoiding scratches. The left and right cylinders are increased, and the cylinder push block adopts a floating push block. The cylinder drives the floating push block to push the end surface of the plastic part to the end surface of the aluminum part. Depending on the positioning of the aluminum part end surface, the step difference between the plastic part and the aluminum part is controlled. The floating push block is pushed by a wire diameter spring on the side, and it will not cause the step difference surface of the product to be uneven due to rigidity. The push block adopts a linear bearing 6 to prevent factors such as the push block from getting stuck.

[0040] The fixture is increased with a top material mechanism. After hot pressing, the product is automatically ejected, and the manipulator takes out the product. The bottom mold heating and cooling dual-purpose plate 12 can better control the hot pressing bonding strength and the flatness of the product.
