Description

Technical Field

[0001] The invention relates to the field of PCB fixtures, and in particular to an R-type contactless loading PCB assembly fixture. Background Art

[0002] PCB, Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, the support of electronic components, and the carrier of electrical connection of electronic components. Because it is made by electronic printing technology, it is called "printed" circuit board.

[0003] When PCBs are transferred, they are stacked and transported by stacking. However, under the action of gravity, the horizontal fixtures will cause the middle parts of the PCBs to contact each other, causing friction between the PCBs. For example, the PCBs of high-end HDI, MSAP, and IC carriers have very thin circuits, which can easily damage the printed circuits during transportation or manual operation. In addition, the fixing stability of the PCBs is poor, which makes it inconvenient to use. A Chinese patent discloses a circuit board storage rack. (Authorization Announcement No. CN203419420U). This patented technology can effectively prevent the surface of the circuit board from being scratched or abraded, but it cannot solve the friction between PCBs placed in the same storage layer; and the inclined setting will have a triangular gap on the upper part, and the space utilization rate is low; there are no limit and protection structures at the front and rear ends of the PCB, resulting in the risk of collision and dumping at the front and rear ends of the PCB.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] See also Figures 1 to 8In this embodiment, an R-type contactless loading PCB assembly fixture is provided, including a first outer plate 1, an inner frame, a second outer plate 11, a slide bar 12, a bulkhead, a relay rod and a synchronization rod. The second outer plate 11 is crimped between the front and rear ends of the two first outer plates 1 to form a rectangular frame. The outer wall cover of the second outer plate 11 away from one end of the first outer plate 1 is provided with a pressing plate 19. The first outer plate 1, the second outer plate 11 and the pressing plate 19 are crimped and assembled by bolts. A synchronization rod is rotatably installed between the pressing plate 19 and the second outer plate 11. The three are assembled separately and have a detachable structure, which is convenient for disassembly and removal of the synchronization rod for maintenance;

[0028] A relay rod is rotatably mounted in the middle of the first outer plate 1 located on the left, and the front and rear ends of the relay rod are respectively meshed and connected with the left ends of the two synchronization rods. The relay rod links the two synchronization rods, and an adjustment head 31 is fixedly mounted on the left end of the synchronization rod located at the front. An assembly hole matching the adjustment head 31 is provided at the left end of the second outer plate 11 located at the front, and one synchronization rod can be rotated by the adjustment head 31, thereby driving the other synchronization rod to rotate synchronously;

[0029] The outer wall of the pressure plate 19 is fixedly mounted with a symmetrically arranged slide rod sleeve 3, and a slide rod 12 is slidably mounted through the middle of the slide rod sleeve 3. The slide rod 12 is fixedly mounted with equidistantly arranged tooth pieces 29 on the side facing the synchronization rod. The tooth pieces 29 are meshed and connected with the synchronization rod, and the slide rod 12 can be driven to extend upward or slide downward by the synchronously rotating synchronization rod, so that multiple slide rods 12 can be synchronously moved up and down, and a single azimuth action can be achieved, so that all slide rods 12 can be synchronously adjusted, and the adjustment is convenient and the synchronization is stable;

[0030] A limit plate 17 is fixedly installed on the top of the slide bar 12, a screw head 18 is fixedly installed in the middle of the top of the limit plate 17, and a top ring 9 is installed on the outer side of the screw head 18 through a threaded connection, so that multiple frames can be stacked and used, and multiple stacked inner frames can be stored at the same time, so that multiple PCB boards can be stacked;

[0031] An inner frame is installed and inserted between the first outer plate 1 and the second outer plate 11, and a partition frame and a PCB board 7 are stacked on the upper part of the inner frame. The partition frame and the PCB board 7 are overlapped, and an inner groove 14 is provided in the middle part of the lower side of the second outer plate 11, and a symmetrically arranged first guide plate groove 20 is provided on the second outer plate 11 toward the inner frame. The inner side of the first guide plate groove 20 is staggered with first guide pieces 10 installed by bolts, and the first outer plate 1 is provided with an equidistantly arranged second guide plate groove 23 on the inner side of the second guide plate groove 23, and the first guide pieces 10 and the second guide pieces 13 are staggered with bolts. The first guide pieces 10 and the second guide pieces 13 limit and guide the PCB board 7 to prevent the PCB board 7 from tipping over or sliding off. At the same time, when stacking, the first guide pieces 10 and the second guide pieces 13 can be inserted into the vacant first guide plate grooves 20 and the second guide plate grooves 23 of the side walls of the upper first outer plate 1 and the second outer plate 11, and the stacked frames are slidably plugged in to achieve stable mutual embedding, thereby ensuring the stacking stability of the device.

[0032] The inner frame includes a latch 2, a first inner plate 4, a middle rod 5 and a second inner plate 8. The second inner plate 8 is fixedly installed with latches 2 arranged in an upper and lower direction at both ends of the front and rear ends. The first inner plate 4 is provided with a socket matched with the latch 2 on the side facing the second inner plate 8. A locking bolt 15 is screwed through the middle of the first inner plate 4, and a middle rod 5 is screwed between the locking bolts 15. The side walls of the first inner plate 4 and the second inner plate 8 are tightly pressed together. A continuous arc groove is provided at the top of the first inner plate 4 and the second inner plate 8. The lowest point of the arc groove is located in the middle of the top of the first inner plate 4. The arc shape can make the PCB board become an arc through its own toughness, and the stacked spacers are used to press the PCB board 7 around to fix it, so as to truly achieve non-contact between the PCB boards 7, avoid the phenomenon that the middle part of the PCB board 7 sags due to gravity and causes wear, and improve the protective effect of the PCB board 7 in the stacked state.

[0033] The partition frame includes a partition 6 and a lifting rod 22. A rectangular opening is set in the middle of the partition 6. The partition 6 adopts a narrow-edge structure. The front and rear outer walls of the partition 6 are fixedly installed with symmetrically set lifting rods 22. Any number of partitions 6 and all PCB boards 7 and partitions 6 on the upper part can be lifted upward by the lifting rods 22 for easy removal and placement.

[0034] The first guide plate 10 and the second guide plate 13 are provided with an inclined guide surface on the upper part of the outer wall facing the inner frame side, which guides the PCB board 7 and the spacer 6 in the center to ensure a high degree of overlap between the upper and lower layers, avoid tilting of the PCB board 7 and the spacer 6 after a large number of layers are stacked, and ensure stable verticality.

[0035] The relay rod includes a long rotating rod 21, a short rotating rod 25, a middle column 26, a spinning sleeve 32 and a transmission head 30. The short rotating rod 25 is fixedly installed on the rear end of the middle column 26, and the long rotating rod 21 is fixedly installed on the front end of the middle column 26. The transmission head 30 is fixedly installed on the rear end of the short rotating rod 25 and the front end of the long rotating rod 21 respectively. The outer side of the short rotating rod 25 is sleeved with a spinning sleeve 32 rotatably installed, and the outer side wall of the spinning sleeve 32 is provided with a threaded groove. The spinning sleeve 32 is assembled and connected with the first outer plate 1 through the threaded groove, and is meshed and transmitted through gears. The meshing is tight, and a large transmission gap occurs when it is placed, resulting in loose meshing and poor assembly stability, thereby ensuring the stability of the support stacking.

[0036] The synchronization rod includes a bevel gear 24, a transmission shaft 27 and a gear 28. The gear 28 is fixedly installed on the outer wall of the transmission shaft 27 at the slide rod 12. The gear 28 is meshed and clamped with the tooth pieces 29 arranged up and down. The left end of the transmission shaft 27 is fixedly installed with a bevel gear 24, which is meshed and connected with the transmission head 30. The synchronization rod can be quickly disassembled, assembled and combined, and the replacement and maintenance are quick and convenient in the later stage of porridge cooking.

[0037] A hexagonal groove is provided in the middle of the left end of the adjusting head 31, and a locking bolt is installed on the left part of the pressure plate 19 located in front of the second outer plate 11 through a threaded connection. The locking bolt is in tight pressure contact with the front side wall of the adjusting head 31. After adjustment, the position of the adjusting head 31 can be tightened, thereby achieving the position of all the sliding rods 12 being fixed, ensuring a stable fixation.

[0038] The working principle of the present invention is:

[0039] This device is used for loading PCB boards. When working, compared with the horizontal fixture currently used in the market, the traditional horizontal loading PCB board will be affected by gravity during loading, causing the middle of the board to sag slightly, which will cause the PCB board to be unable to completely isolate the contact between the PCB boards. This device adopts a special-shaped fixture through its own research and development. The top of the first inner plate 4 and the second inner plate 8 are provided with continuous arc grooves. The lowest point of the arc groove is located in the middle of the top of the first inner plate 4. The arc shape can make the PCB board become an arc through its own toughness. With the stacked spacers, the PCB board is pressed around to fix it, so that the PCB board circuit is suspended, and each layer of PCB board is truly contactless.

[0040] By setting the relay rod, the synchronous rod and the slide rod 12, the action of a single position can be realized, and the synchronous adjustment of all the slide rods 12 can be realized, the adjustment is convenient and the synchronization is stable, the gears are meshed and the meshing is tight, and the transmission gap is large when placed, resulting in loose meshing and poor assembly stability, ensuring the stability of the support stacking, and the synchronous rod can be quickly disassembled and assembled by crimping through threaded rotation, and the replacement and maintenance of the porridge in the later stage are quick and convenient;

[0041] By setting the adjustment head 31, the first guide plate 10 and the second guide plate 13, when stacking, the first guide plate 10 and the second guide plate 13 can be inserted into the vacant first guide plate groove 20 and the second guide plate groove 23 of the side walls of the upper first outer plate 1 and the second outer plate 11, and the stacked frames can be slidably plugged to achieve stable mutual embedding, thereby ensuring the stacking stability of the device. After adjustment, the position of the adjustment head 31 can be pressed, thereby achieving that the positions of all the slide bars 12 are fixed, thereby ensuring the stable fixation;

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
