Description

Technical Field

[0001] The present invention relates to a pressing bearing plate, and more specifically, to a pressing bearing plate for a PCB board. Background Art

[0002] PCB, or printed circuit board, is a common substrate in electronic products. It is responsible for connecting various electronic components together to realize circuit functions. In the PCB manufacturing process, lamination is a key link, which mainly forms a whole by applying pressure and temperature to prepreg, copper foil and other plates. This process is crucial to ensure the quality and performance of the circuit board.

[0003] In the process of laminating and stacking the panels, a steel or aluminum partition with an insulating layer on the surface is first placed on the carrier plate, and the panels that make up one PCB board are stacked on the partition in sequence, and the partition is used to block the panels on the upper and lower PCB boards. In the existing laminating process, it is usually necessary to install a liftable positioning block on the carrier plate to position the corners of the partition. Since the positioning block is installed on the carrier plate, in order to leave lifting space, the positioning block cannot contact the partition on the bottom layer for positioning. And after the laminating is completed, the positioning block is in a fixed state. In order to ensure the laminating, the height of the upper end of the positioning block is less than the height of the panel and cannot position the baffle on the top layer. Summary of the invention

[0004] The purpose of the present invention is to provide a PCB board pressing carrier with a compact structure and convenient positioning in view of the above-mentioned deficiencies in the prior art.

DETAILED DESCRIPTION

[0024] See also Figure 1-6 As shown, a PCB board pressing carrier of the present invention comprises a carrier plate 1 for placing PCB board raw materials, four liftable right-angle baffles 2 are arranged on the carrier plate 1, a first lifting groove 3 for installing the right-angle baffles 2 is arranged at the bottom of the carrier plate 1, a first spring 4 is arranged in the first lifting groove 3; and a limiting frame 5 is sleeved on the outer side of the right-angle baffle 2. By arranging the first lifting groove and the first spring at the bottom of the carrier plate, the right-angle baffle can limit the partition, and at the same time, when pressing is performed on the upper side, the right-angle baffle can be lowered with the plate, ensuring that all the partitions can be positioned and aligned by the right-angle baffle during the stacking process, so as to ensure the pressing.

[0025] During the experiment, it was found that if the layers of plate materials are not aligned during stacking, uneven force will occur during the pressing process, causing the partition to tilt or deviate to one side, and applying thrust to the right-angle baffle on one side to cause tilting, which may cause the right-angle baffle to be unable to move downward, affecting the pressing. The right-angle baffle is limited in the horizontal direction by the limit frame to ensure that the inner wall of the right-angle baffle can fit tightly with the edge of the partition, prevent the right-angle baffle from tilting outward, and ensure that the partition will not tilt or deviate to one side, ensuring that the pressing is carried out.

[0026] A connecting structure for installing the first spring is provided on the inner bottom surface of the first lifting groove and the bottom of the right-angle baffle, such as a boss adapted to the inner diameter of the first spring. This is common knowledge for those skilled in the art and will not be elaborated here.

[0027] In this embodiment, side baffles 6 are provided on both sides of the carrier plate 1 along the length direction, a second lifting groove 7 for installing the side baffles 6 is provided at the bottom of the carrier plate 1, and a second spring 8 is provided in the second lifting groove 7. Providing side baffles on both sides to position the two sides of the baffle can further improve the positioning accuracy of the partition, and the two long sides are easier to position than when only the four corners are positioned.

[0028] In this embodiment, preferably, a mounting frame 9 is provided at the bottom of the carrier plate 1, and the first lifting slot 3 is detachably arranged in the mounting frame 9; a positioning baffle 10 is provided on the inner side of the mounting frame 9, and a plurality of clamping springs 11 are symmetrically provided on both sides of the mounting frame 9; the surface of the clamping spring 11 is located on the same plane as the inner surface of the mounting frame 9, and a plurality of spherical clamping blocks 12 are evenly distributed on the surface of the clamping spring 11. The first lifting slot is set to be detachable, which is convenient for installing and replacing the first spring. In the initial state, the spacing between the clamping blocks on both sides is slightly smaller than the width of the first lifting slot. When the limit frame applies horizontal limit to the right-angle baffle, the first lifting slot is only subjected to vertical thrust during the pressing process, so the first lifting slot can be stably installed by the clamping spring.

[0029] In this embodiment, the second lifting slot adopts the same installation structure as the first lifting slot.

[0030] In this embodiment, a plurality of mounting grooves 13 for mounting the clamping spring piece 11 are provided on both sides of the mounting frame 9, and positioning protrusions 14 are provided in the mounting grooves 13; mounting end plates 15 are provided at both ends of the clamping spring piece 11, and positioning notches 16 matching the positioning protrusions 14 are provided on the mounting end plates 15. This structure facilitates the installation and replacement of the clamping spring piece, and after the clamping spring piece is bent, the positioning notch and the positioning protrusion are matched from the side so that the mounting end plate enters the mounting groove.

[0031] In addition, the height of the installation slot can be set to the sum of the height of the clamping spring piece and the height of the positioning protrusion. During installation, first insert the installation end plate into the installation slot from above the positioning protrusion and then move the positioning notch downward to match the positioning protrusion, thereby further improving the convenience of disassembly and assembly of the clamping spring piece.

[0032] Further preferably, a diamond-shaped spring piece 17 is provided on the outer wall of the first lifting slot 3 at one end inside the installation frame 9, and a positioning hole 18 matching the diamond-shaped spring piece 17 is provided on the positioning baffle 10; a handle 19 is provided on the outer wall at the end opposite to the diamond-shaped spring piece 17. The diamond-shaped spring piece is provided to cooperate with the positioning hole to further fix the first lifting slot, so as to avoid shaking during the process of moving the carrier plate into the pressing machine, resulting in the first lifting slot being offset, causing the right-angle baffle to tilt and get stuck, or causing the first lifting slot to be separated from the installation frame.

[0033] In this embodiment, the limit frame 5 includes two first beams 5a, and a second beam 5b is vertically arranged between the two ends of the two first beams 5a; guide grooves 5c are arranged at both ends of each first beam 5a, and guide rods 5d cooperating with the guide grooves 5c are arranged at both ends of the second beam 5b, and a first limit plate 5e and a second limit plate 5f are respectively arranged at the free ends of the guide grooves 5c and the guide rods 5d. With this structure, the limit frame can be freely adjusted in size, can be used with carrier plates of different sizes, and is more convenient to cooperate with the limit frame and the four right-angle baffles.

[0034] The bearing plate 1 outside the right-angle baffle 2 is provided with a threaded hole 5g, and a positioning plug-in 20 is threadedly connected to the threaded hole 5g; when the inner side surfaces of the first crossbeam 5a and the second crossbeam 5b are in contact with the surface of each right-angle baffle 2, they are fixed by the positioning plug-in 20. The positioning plug-in provided on the bearing plate limits the outer side of the rectangle formed by the first crossbeam and the second crossbeam, so that the disassembly and assembly can be performed quickly, which is convenient and quick.

[0035] Preferably, the positioning plug-in 20 includes a threaded shaft 20a matched with the threaded hole 5g, an inverted cone-shaped positioning block 20b is provided at the upper end of the threaded shaft 20a, and the first crossbeam 5a and the guide rod 5d are both provided with a rounded corner portion matched with the positioning block 20b; a torsion ring 20c is provided at the upper end of the positioning block 20b for easy rotation. By providing the rounded corner portion to match the inverted cone-shaped positioning block, the force applied to the first crossbeam and the guide rod will become greater and greater during the process of tightening the inverted cone-shaped positioning block downward, so that the limit frame and the right-angle baffle are more closely matched.

[0036] In this embodiment, a bottom plate 21 corresponding to the carrier plate 1 is provided at the bottom of the first lifting slot 3. The existing feeding method of the press machine is to first place the carrier plate on the material preparation vehicle for material preparation, and then transport the carrier plate loaded with the plate into the press machine through the transport rollers on the material preparation vehicle and in the press machine. The bottom plate is provided to facilitate the cooperation with the transport roller, so as to avoid bumping or jamming of the bottom edge of the first lifting slot when passing through the gap between the two transport rollers during transportation.

[0037] During operation, place the base plate of the carrier plate on the material preparation vehicle, insert the first lifting slot and the second lifting slot into the corresponding installation frames respectively, put the right-angle baffle and the side baffle into the first lifting slot and the second lifting slot respectively, place the limit frame on the carrier plate so that the first crossbeam and the second crossbeam are respectively attached to the outer walls corresponding to each right-angle baffle, lock the positioning blocks at the four corners, stack the partitions and plates according to production needs in the rectangular space formed by the right-angle baffles and the side baffles and wait for pressing.

[0038] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the description of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
