[0031] As shown in Figure 1 As shown in Figure 4 The embodiment provides a circuit board copper foil substrate pressing device for tablet computer, which comprises a support 1 serving as a carrier. The support 1 is provided with a limiting assembly 2 for limiting the position of the circuit board copper foil substrate, and is also provided with a pressing assembly 3 for pressing the circuit board copper foil substrate.

[0032] The limiting assembly 2 comprises a rotating disc 21 in the shape of a circle rotatingly installed in the support 1, the rotating disc 21 is provided with rotating grooves 22 in the shape of an arc and arranged in an array along the center of the rotating disc 21, and the rotating grooves 22 are used for limiting the position of a push block 26. The rotating disc 21 is provided, above, with a support block 23 in the shape of a cross fixedly installed on the support 1, the support block 23 is fixedly connected with a workbench 24, and the workbench 24 is used for carrying the circuit board copper foil substrate to be processed. The support block 23 is slidably connected with a sliding rod 25, and the sliding rod 25 is used for connecting and driving a lamination assembly 27. One end of the sliding rod 25 is fixedly connected with the push block 26 slidably installed in the rotating groove 22, and the other end of the sliding rod 25 is detachably installed with the lamination assembly 27 close to or away from the workbench 24. The support 1 is provided with a driving assembly 28 for driving the rotating disc 21 to rotate.

[0033] As shown in Figure 2 As shown in Figure 3 As shown in Figs. 1 and 2, the lamination assembly 27 comprises a connecting plate 271 fixedly installed on the end of the sliding rod 25, the connecting plate 271 is detachably installed with a clamping plate 272, and the connecting plate 271 and the clamping plate 272 are threadedly installed with a bolt 273. The bolt 273 can conveniently and timely detach the clamping plate 272.

[0034] The clamping plate 272 is higher than the workbench 24 and much larger than the thickness of the copper foil substrate of the circuit board to be processed, so that the copper foil substrate of the circuit board can be stably and effectively positioned.

[0035] The driving assembly 28 comprises a worm 281 rotatably installed in the bracket 1, which is driven by a worm gear 282. One side of the worm 281 is connected with the worm gear 282 rotatably installed in the bracket 1, one end of the worm gear 282 is fixedly connected with the turntable 21, and the bracket 1 is fixedly connected with a motor 283 for driving the worm 281 to rotate. The motor 283 serves as a driving source to reduce manual operation of workers. The worm gear 282 can be kept in a fixed position under the action of the worm 281 after stopping rotating due to the self-locking property, and will not be displaced due to external vibration, pressure and other factors. The copper foil substrate can be kept in a stable positioning state during a long pressing process, and problems such as displacement and misplacement of the circuit board caused by loose positioning can be avoided.

[0036] As shown in Figure 4 The pressing assembly 3 comprises a pressing plate 31 slidably installed on the bracket 1, and a cylinder 32 fixedly installed on the bracket 1 for driving the pressing plate 31 to slide in the vertical direction.

[0037] The pressing plate 31 and the workbench 24 are matched in shape and size, and the pressing plate 31 is located above the workbench 24 and parallel to the workbench 24. This ensures that the copper foil substrate of the circuit board can be stably and accurately pressed.

[0038] The pressing plate 31 and the workbench 24 are both provided with ceramic heating sheets 4. When current passes through the ceramic heating sheets 4 with certain resistance, electrons moving in the resistance material will collide with atoms, converting electrical energy into heat energy, so that the ceramic heating sheets 4 generate heat. The upper and lower heating mode is adopted, and high-performance heating elements are embedded in the pressing plate 31 and the workbench 24. Heated pipes and the like can also be used. This uniform heating mode can make the copper foil substrate more evenly heated during pressing, avoiding problems such as uneven pressing quality caused by local overheating or overcooling.

[0039] In use, first start the motor 283, drive the worm 281 through it to make the rotating disc 21 rotate, make the push block 26 drive the slide rod 25 to slide under the restriction of the rotating groove 22 of the rotating disc 21 and the supporting block 23. Make the clamping plate 272 away from the workbench 24 under the drive of the slide rod 25. At the same time, start the power supply to heat the pressing plate 31 and the workbench 24, then put the circuit board copper foil substrate to be processed on the workbench 24, drive the clamping plate 272 to close to the workbench 24 through the motor 283, thereby limiting the circuit board copper foil substrate on the workbench 24. The circuit board copper foil substrate pressing device for tablet computer can effectively reduce the possibility of position deviation of the circuit board copper foil substrate, ensure the accuracy of the line connection, and make the copper foil substrate uniformly stressed during the pressing process, avoid the combination between the copper foil and the substrate not being tight or bubbles, delamination and other defects caused by excessive or insufficient local pressure. Reduce the scrap rate, reduce the consumption of raw materials, and reduce the production cost.
