Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and particularly relates to a device for fixing a PCB board body mold. Background Art

[0002] The PCB board body refers to the main part of a printed circuit board, which is an indispensable component in modern electronic devices. It provides mechanical support for electronic components, connects electronic components through conductive paths, and realizes the transmission and distribution of electrical signals. Since the PCB board body needs to be installed in an electronic device, generally speaking, the thickness of the PCB board body is relatively small. The thickness of the PCB is usually between 0.4 mm and 4.0 mm, and the most commonly used thickness is 1.6 mm. When processing the PCB board body, a fixing mold is required to clamp the PCB board body to achieve stable processing of the PCB board body.

[0003] In the existing patent CN106973503A, a PCB board body fixing mold device for a PCB board splitting machine is disclosed, which includes a lower mold. The middle part of the top surface of the lower mold has a placement groove, and the bottom surface of the placement groove has a mounting convex plate. There is an empty groove between the mounting convex plate and the inner side wall of the placement groove. The middle part of the mounting convex plate has a plurality of mutually parallel transverse grooves and a vertical groove, and the transverse grooves and the vertical groove divide the mounting convex plate into a plurality of convex parts. The edge part of the top surface of the lower mold has a plurality of positioning concave holes. The upper pressing plate presses against the top surface of the lower mold. The bottom edge part of the upper pressing plate has convex columns, and the convex columns are inserted into the corresponding positioning concave holes. The middle part of the upper pressing plate has a main through groove. The PCB board body is inserted into the placement groove, and the PCB board body is clamped between the upper pressing plate and the mounting convex plate. It can automatically fix the PCB board body, with firm fixation and convenient installation and disassembly.

[0004] In the above structure, the effect of fixing and clamping the PCB board body can be achieved. However, when processing the PCB board body, since the thickness of the PCB board body is relatively small, it is difficult to put the PCB board body into the mold or take it out of the mold. When putting it in, the PCB board body is prone to friction with the mold, causing damage to the PCB board body. When taking it out, the PCB board body is small and it is difficult to remove it from the mold inside the mold, which is not conducive to the operation of putting in or taking out the PCB board body, not conducive to the processing of the PCB board body, thereby reducing the processing efficiency of the PCB board body and increasing the production cost of the enterprise.

[0005] Therefore, how to provide a device for a PCB board body fixing mold is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0031] Embodiment 1:

[0032] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 shown, a device for a PCB board body fixing mold of the present invention includes a lower mold 1, a downward pressing component 2 is arranged on the lower mold 1, an attracting component 3 is arranged between the lower mold 1 and the downward pressing component 2, a bearing component 4 for bearing the PCB board body is arranged on the lower mold 1, a supporting component 5 is arranged on the bearing component 4, a sliding component 6 is arranged on the lower mold 1, an adjusting component 7 is arranged on the sliding component 6, the adjusting component 7 is used for adjusting the state of the supporting component 5, a transmission component 8 is arranged between the downward pressing component 2 and the adjusting component 7, a clamping component 9 for clamping the bearing component 4 is arranged on the lower mold 1, and a driven component 10 is arranged between the adjusting component 7 and the clamping component 9; wherein, when the downward pressing component 2 opens, the downward pressing component 2 forces the transmission component 8 to rotate, when the transmission component 8 moves to the first state, the adjusting component 7 forces the driven component 10 to drive the clamping component 9 to move, so that the clamping component 9 unlocks the bearing component 4; when the transmission component 8 moves to the second state, the transmission component 8 continues to move, and the adjusting component 7 drives the supporting component 5 and the bearing component 4 to move vertically; when the transmission component 8 moves to the third state, the transmission component 8 continues to move, and the adjusting component 7 drives the supporting component 5 and the bearing component 4 to move horizontally, so that the bearing component 4 moves away from the lower mold 1.

[0033] Working principle: After the PCB board body is processed, the attracting component 3 is used to release the pressing component 2 and the lower die 1, and the pressing component 2 is rotated so that the pressing component 2 moves away from the lower die 1. When the pressing component 2 drives the transmission component 8 to move to the first state, the transmission component 8 rotates to drive the adjusting component 7 to move, the adjusting component 7 moves to drive the driven component 10 to move, and the driven component 10 moves to drive the clamping component 9 to move, so that the clamping component 9 moves away from the bearing component 4, and the bearing component 4 is released. At this time, the adjusting component 7 moves into contact with the supporting component 5; when the pressing component 2 drives the transmission component 8 to move to the second state, the pressing component 2 continues to rotate, and the pressing component 2 drives the transmission component 8 to continue to move, so that the transmission component 8 drives the adjusting component 7 to continue to move. Since the pressing component 2 is in contact with the supporting component 5, at this time, the adjusting component 7 forces the supporting component 5 to move, so that the supporting component 5 jacks up the bearing component 4, and the bearing component 4 automatically moves along the vertical direction of the lower die 1 until the bearing component 4 slides out of the lower die 1. At this time, the supporting component 5 moves to the top of the adjusting component 7; when the pressing component 2 drives the transmission component 8 to move to the third state, the pressing component 2 continues to rotate, and the transmission component 8 drives the adjusting component 7 to continue to move. Since the pressing component 2 moves to the top of the adjusting component 7, when the adjusting component 7 restricts the movement of the supporting component 5, the adjusting component 7 and the supporting component 5 form an integral body. When the transmission component 8 drives the adjusting component 7 to move, the adjusting component 7 drives the supporting component 5 to move horizontally, so that the supporting component 5 drives the bearing component 4 to automatically move along the horizontal direction of the lower die 1 until the bearing component 4 slides out horizontally from the lower die 1. At this time, the bearing component 4 drives the PCB board body to be exposed from the lower die 1. When it is necessary to replace or remove the PCB board body, the staff can directly operate on the PCB board body without the human body or tools reaching into the interior of the lower die 1; similarly, after the PCB board body is placed on the bearing component 4, the pressing component 2 is started in the reverse direction to force the PCB board body and the bearing component 4 to move into the interior of the lower die 1, and the device is used to perform processing operations on the PCB board body; in summary, a device for a PCB board fixing die in the present application realizes the conversion of multiple states by the movement of the pressing component 2, reduces the waiting time between steps, improves the action continuity of the device, can simulate the movement track of a device or a human hand, enables the bearing component 4 to automatically take out or put into the lower die 1, so as to facilitate the taking and placing of the PCB board body, avoid friction damage between the PCB board body and the lower die 1 when putting it in, and when removing the PCB board body, the PCB board body is far away from the lower die 1, which is convenient for the staff to operate, thereby improving the automation function of the device, facilitating the processing of the PCB board body, improving the processing efficiency of the PCB board body, and reducing the production cost of the enterprise.

[0042] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, a device for a PCB board fixing mold of the present invention, the clamping assembly 9 includes a rotating rod 901 bearing-connected to the lower mold 1, a threaded rod 902 is arranged on the rotating rod 901, the two threaded rods 902 have opposite thread structures, a guide rod 903 is arranged on the lower mold 1, a movable block 904 is threadedly connected to the threaded rod 902, the threaded rod 902 threadedly penetrates through the movable block 904, the guide rod 903 penetrates through the movable block 904, and a clamping block 905 for clamping the carrier plate 404 is arranged on the movable block 904.

[0043] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, a device for a PCB board fixing mold of the present invention, the driven assembly 10 includes a connecting rod 1001 arranged on the adjusting plate 701, a driven straight rack 1002 is arranged on the connecting rod 1001, and a driven gear 1003 meshing with the driven straight rack 1002 is fixedly sleeved on the rotating rod 901.

[0044] Working principle: After the PCB board is processed, the electromagnet 301 is powered off, so that the magnetism of the electromagnet 301 disappears, and the electromagnet 301 cannot attract the magnet block 302. At this time, the lower pressing plate 202 and the lower mold 1 are released, and the lower pressing plate 202 is rotated manually by the equipment or the staff;

[0045] When the lower pressing plate 202 rotates upward, the lower pressing plate 202 drives the lower pressing head 203 to rotate, so that both the lower pressing plate 202 and the lower pressing head 203 move away from the lower die 1, thereby releasing the carrier plate 404. When the lower pressing plate 202 rotates to the first state, the lower pressing plate 202 drives the shaft rod 201 to rotate as it rotates. The shaft rod 201 drives the transmission gear 801 to rotate. The transmission gear 801 drives the transmission straight rack 803 to move. The transmission straight rack 803 drives the connecting plate 802 to move. The connecting plate 802 drives the adjusting plate 701 to move closer to the roller 704. The adjusting plate 701 drives the sliding block 601 to move. The sliding block drives the sliding rod 602 to move. Under the action of the baffle 603, the sliding spring 604 is compressed. The movement of the adjusting plate 701 drives the connecting rod 1001 to move synchronously. The connecting rod 1001 drives the driven straight rack 1002 to move. The driven straight rack 1002 drives the driven gear 1003 to rotate. The driven gear 1003 drives the rotating rod 901 to rotate. The rotating rod 901 drives the threaded rod 902 to rotate. The threaded rod 902 drives the movable block 904 and the clamping block 905 to move, so that the two clamping blocks 905 move away from the carrier plate 404, causing the clamping blocks 905 to release the carrier plate 404. At this time, the inclined surface 702 contacts the roller 704, and the driven straight rack 1002 is separated from the driven gear 1003;

[0046] When the lower pressing plate 202 rotates to the second state, the lower pressing plate 202 continues to rotate. The lower pressing plate 202 drives the shaft rod 201 to rotate as it rotates. The shaft rod 201 drives the transmission gear 801 to rotate. The transmission gear 801 drives the transmission straight rack 803 to move. The transmission straight rack 803 drives the connecting plate 802 to move. The connecting plate 802 drives the adjusting plate 701 to move, forcing the roller 704 to move on the inclined surface 702. The adjusting plate 701 drives the sliding block 601 to move. The sliding block drives the sliding rod 602 to move. Under the action of the baffle 603, the sliding spring 604 is compressed. When the adjusting plate 701 is moving, due to the setting of the inclined surface 702, when the inclined surface 702 is moving, the roller 704 will move upward. The roller 704 drives the mounting block 504, the inner rod 503, the support outer cylinder 502 and the support spring 505 to move upward. At this time, due to the action of the support spring 505, the inner rod 503 will not move within a certain force range. Among them, when the force exceeds a certain value, the support spring 505 will be compressed, and the inner rod 503 slides in the support outer cylinder 502. The support outer cylinder 502 moves upward, forcing the support rod 501 to move upward. The support rod 501 drives the carrier plate 404 to move upward. The carrier plate 404 drives the carrier slider 403 to move upward in the vertical groove 401, so that the carrier plate 404 automatically moves along the vertical direction of the lower die 1 until the carrier plate 404 drives the PCB board to slide out of the lower die 1 until the mounting block 504 and the roller 704 move to the top of the adjusting plate 701;

[0047] When the lower pressing plate 202 rotates to the third state, the lower pressing plate 202 continues to rotate, the rotation of the lower pressing plate 202 drives the shaft 201 to rotate, the rotation of the shaft 201 drives the transmission gear 801 to rotate, the rotation of the transmission gear 801 drives the transmission spur rack 803 to move, the transmission spur rack 803 drives the connecting plate 802 to move, the connecting plate 802 drives the adjusting plate 701 to move, and the roller 704 is forced to move into the limiting hole 703, so that the limiting hole 703 forms a limiting effect on the roller 704, so that the adjusting plate 701, the roller 704 and the supporting plate 701 are The component 5 is formed into one body. When the adjustment plate 701 moves, the adjustment plate 701 drives the roller 704 and the support component 5 to move horizontally synchronously, so that the support rod 501 drives the carrier plate 404 to automatically move along the horizontal direction of the lower mold 1, until the carrier plate 404 drives the PCB board to slide out horizontally from the lower mold 1; at this time, the carrier plate 404 drives the PCB board to be exposed from the lower mold 1. When the PCB board needs to be replaced or removed, the staff can directly operate the PCB board without the need for human body or tools to probe into the lower mold 1;

[0048] When placing the PCB body, after placing the PCB body on the carrier plate 404, the lower pressing plate 202 is rotated in the opposite direction to force the PCB body and the carrier plate 404 to move to the inside of the lower mold 1 until the lower pressing plate 202 moves to a reasonable position, so that the lower pressing plate 202 presses down the carrier plate 404 and the PCB body. At this time, the clamping block 905 clamps the carrier plate 404, thereby forming a clamping effect on the PCB body, and the equipment is used to perform processing operations on the PCB body.

[0049] This solution utilizes the movement of the lower pressing plate 202 to realize the conversion of multiple states, reduces the waiting time between steps, improves the action continuity of the device, and can simulate the movement trajectory of equipment or human hands, so that the carrier plate 404 is automatically taken out of the lower mold 1 or automatically placed in the lower mold 1, thereby facilitating the removal and placement of the PCB board, avoiding the friction between the PCB board and the lower mold 1 when placing it. When removing the PCB board, the PCB board is away from the lower mold 1, which is convenient for the staff to operate, thereby improving the automation function of the device, facilitating the processing of the PCB board, improving the processing efficiency of the PCB board, and reducing the production cost of the enterprise.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
