The hot pressing assemblies are vertically mounted on the movable ends of the drive cylinders and are linked to the slide rail assemblies. One heating adjustment section is fixed to the lower end of one hot pressing assembly. Several modules suitable for fixing thermally conductive adhesive plates are rotatably mounted on the heating adjustment section. The drive cylinders are adapted to drive the heating adjustment section to slide downwards to hot press the chip. Rotating the corresponding modules fixes the thermally conductive adhesive plates to accommodate chips of different specifications. Several positioning blocks limit and fix the thermally conductive adhesive plates to accommodate chips of different sizes, improving work efficiency. However, this technology still has the following problems:

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A chip hot pressing fixture for easy workpiece handling, comprising a fixture base 1;

[0031] The fixture base 1 is equipped with a dual-work platform transfer mechanism 2 for rotating the worktable;

[0032] The dual-work platform transfer mechanism 2 is equipped with two sets of cylindrical workpiece fixing and rotating mechanisms 3 for fixing the cylindrical workpiece 4 and automatically rotating the cylindrical workpiece 4. The two sets of cylindrical workpiece fixing and rotating mechanisms 3 are symmetrical about the center point of the dual-work platform transfer mechanism 2.

[0033] The cylindrical workpiece fixing and rotating mechanism 3 includes a clamping component 31 and a rotating component 32; the clamping component 31 is connected to the dual working platform transfer mechanism 2, the clamping component 31 is connected to the rotating component 32, and the rotating component 32 is connected to the dual working platform transfer mechanism 2.

[0034] The operator places the cylindrical workpiece 4 above and close to the rotating component 32, and then places the cylindrical workpiece 4 on the outer wall of the clamping component 31. The clamping component 31 then clamps the cylindrical workpiece 4, so that the cylindrical workpiece 4 is clamped and fixed on the double working platform transfer mechanism 2 by the clamping component 31 and the rotating component 32. While the double working platform transfer mechanism 2 sends the cylindrical workpiece 4 to the hot pressing position, it sends another set of cylindrical workpiece fixing rotating mechanism 3 to the loading and unloading side for loading. After the cylindrical workpiece 4 under the hot press is adjusted to a suitable position by the rotating component 32 and the hot pressing is completed, the double working platform transfer mechanism 2 sends the hot-pressed cylindrical workpiece 4 back to the loading and unloading side. At the same time, the other set of loading cylindrical workpiece fixing rotating mechanism 3 is sent to the hot pressing side. The dual-working-platform transfer mechanism 2 includes a rotary cylinder 21 and a rotating platform 22; the drive end of the rotary cylinder 21 passes through the fixture base 1 and is fixedly connected to the rotating platform 22, the rotary cylinder 21 is fixedly connected to the inner bottom of the fixture base 1, and the rotating platform 22 is rotatably connected to the fixture base 1.

[0035] This invention enables operators to more easily fix cylindrical workpieces 4 when they have multiple slots that need to be fixed and hot-pressed, without having to manually adjust the hot-pressing positions one by one, thus improving processing efficiency.

[0036] The dual-working-platform transfer mechanism 2 includes a rotary cylinder 21 and a rotating platform 22; the drive end of the rotary cylinder 21 passes through the fixture base 1 and is fixedly connected to the rotating platform 22, the rotary cylinder 21 is fixedly connected to the inner bottom of the fixture base 1, and the rotating platform 22 is rotatably connected to the fixture base 1.

[0037] After the operator fixes the workpiece body 41 on the clamping component 31 and rotating component 32 on the loading and unloading side, the driving end of the rotary cylinder 21 drives the rotating platform 22 to rotate, sending the fixed cylindrical workpiece 4 to the hot pressing position. At the same time, the clamping component 31 and rotating component 32, which were originally in the hot pressing position, are sent to the loading and unloading position for loading. After the hot pressing is completed, the driving end of the rotary cylinder 21 drives the rotating platform 22 to rotate again, sending the hot-pressed cylindrical workpiece 4 to the loading and unloading station. At the same time, the newly loaded cylindrical workpiece 4 is sent to the hot pressing station for processing.

[0038] This invention enables operators to more easily fix cylindrical workpieces 4 when they have multiple slots that need to be fixed and hot-pressed, without having to manually adjust the hot-pressing positions one by one, thus improving processing efficiency.

[0039] The clamping assembly 31 includes a cylinder 311, a cylinder mounting bracket 312, a limiting groove 313, and a clamping roller 314. The lower end of the cylinder 311 is fixedly connected to the top end of the cylinder mounting bracket 312. The cylinder mounting bracket 312 has a limiting groove 313 on its inner side in the vertical direction to limit the driving end of the cylinder 311. The bottom of the cylinder mounting bracket 312 is fixedly connected to the rotating platform 22. The driving end of the cylinder 311 is rotatably connected to the clamping roller 314 that clamps the workpiece. The cylindrical workpiece 4 is slidably connected to the outer wall of the clamping roller 314.

[0040] The rotating assembly 32 includes a motor 321, a first rotating roller 322, a second rotating roller 323, and a workpiece stop 324. The first rotating roller 322 is fixedly connected to the rotating platform 22. One end of the first rotating roller 322 near the middle of the rotating platform 22 is fixedly connected to the driving end of the motor 321. The motor 321 is fixedly connected to the rotating platform 22. The second rotating roller 323 is rotatably connected to the rotating platform 22. A workpiece stop 324 for positioning the cylindrical workpiece 4 is fixedly installed on one end of the first rotating roller 322 near the motor 321. The first rotating roller 322 and the second rotating roller 323 are at the same height and are arranged in parallel.

[0041] The clamping roller 314 is rolledly connected to the inner wall of the cylindrical workpiece 4, the rotating roller 1 322 is rolledly connected to the outer wall of the cylindrical workpiece 4, the rotating roller 2 323 is rolledly connected to the outer wall of the cylindrical workpiece 4, the workpiece body 41 and the workpiece abutment block 324 are slidably connected, and multiple chip slots 42 are opened on the outer wall of the cylindrical workpiece 4.

[0042] The outer walls of rotating roller 2 322, rotating roller 1 323, and pressing roller 314 are all covered with a rubber layer to increase friction.

[0043] The side where the operator is located is the loading and unloading station, and the side where the hot pressing is located is the hot pressing station. The operator places the workpiece body 41 at the loading and unloading station onto the outer wall of the clamping roller 314 of a set of clamping components 31 at the loading and unloading station. The workpiece body 41 is placed on the upper part of the rotating rollers 322 and 323 of a set of rotating components 32. The workpiece abutment 324 is used to hold the cylindrical workpiece 4 against to prevent it from sliding backward. At this time, the driving end of the cylinder 311 drives the clamping roller 314 to move in the limiting slide groove 313. The workpiece body 41 is pressed against the limit position, and then the dual working platform transfer mechanism 2 sends the workpiece body 41 to the hot pressing station. At the same time, another set of pressing components 31 and another set of rotating components 32 are rotated to the loading and unloading station. The rotating roller 322 below the workpiece body 41 in the hot pressing position is driven to rotate by the motor 321 behind it. The rotation of the rotating roller 322 rotates the chip slot 42 to adjust the hot pressing position. The rotation of the workpiece body 41 drives the rotating roller 323 and the pressing roller 314 to rotate.

[0044] This invention enables operators to more easily fix cylindrical workpieces 4 when they have multiple slots that need to be fixed and hot-pressed, without having to manually adjust the hot-pressing positions one by one, thus improving processing efficiency.
