[0014] The present invention also provides a process for preparing a PCB circuit board, which is applied to the circuit board structure of the PCB circuit board as described above, and comprises the following steps:

[0015] S1. Twist the limiting sleeve on the surface of the inner rod. The limiting sleeve and the inner rod are spirally matched to make the limiting sleeve move on the surface of the inner rod. The moving limiting sleeve and the elastic force of the spring are matched to adjust the slide plate, so that the slide plate can be moved on the top of the base. The relative distance between the two slide plates is adjusted in real time according to the length of the circuit board, and the circuit board is placed on the top surfaces of the two slide plates accordingly.

[0017] S3, twist the rotating sleeve. Since the rotating plate limits the outer end of the sliding rod through the rotating rod, the rotating sleeve rotates on the inner end surface of the sliding rod. The rotating rotating sleeve makes the two opposite sliding rods approach each other. The moving sliding rod pulls the rotating rod to slide inside the arc groove, and the moving rotating rod drives the rotating plate to rotate. The moving rotating rod drives the outer ring to squeeze the end surface of the circuit board using the circular plate;

[0018] S4. The reaction force of the circuit board end face on the outer ring causes the outer ring to deform, and the outer ring cooperates with the circular plate to extrude the elastic ring. The deformed outer ring uses the insertion rod to drive the pressure plate to move, and the moving pressure plate slides on the surface of the side rod, and the moving pressure plate drives the top of the connecting plate to move. Since the pressure plate cooperates to limit the top of the connecting plate, the connecting plate rotates driven by the pressure plate, and the bottom end of the rotating connecting plate pushes the pressure rod downward. The downward pressure rod uses the bottom plate to extrude the top surface of the slide plate, and the circular plate is limited by the extrusion force of the bottom plate and the slide plate. Multiple circular plates use the outer ring outside the elastic ring to limit the circuit board, thereby improving the stability of circuit board installation.

[0019] Technical effects and advantages of the present invention:

[0020] 1. When the present invention squeezes the end face of the circuit board through the outer ring on the outer side of the circular plate, the deformed outer ring rotates the connecting plate through the pressure plate on the inner side of the plug rod, and the bottom end of the rotating connecting plate pushes the pressure rod to move downward, and the downward pressure rod uses the bottom plate to squeeze the top surface of the slide plate, and the circular plate is limited by the extrusion force of the bottom plate and the slide plate, thereby ensuring the limiting effect of the circular plate on the top of the slide plate and preventing the circular plate from moving arbitrarily. Multiple circular plates use the outer ring on the outer side of the elastic ring to limit the circuit board, thereby improving the stability of circuit board installation.

[0021] 2. The present invention twists the limiting sleeve on the surface of the inner rod, and the spiral cooperation between the limiting sleeve and the inner rod enables the limiting sleeve to move on the surface of the inner rod. The moving limiting sleeve cooperates with the elastic force of the spring to adjust the slide plate, so that the slide plate can be moved on the top of the base conveniently, and the relative distance between the two slide plates can be adjusted in real time according to the length of the circuit board.

[0022] 3. When the present invention squeezes the end face of the circuit board through the outer ring, the reaction force of the end face of the circuit board on the outer ring causes the outer ring to deform, and the outer ring cooperates with the circular plate to squeeze the elastic ring. The deformed outer ring uses the insertion rod to drive the pressure plate to move, and the squeezing force of the circular plate on the end face of the circuit board is reduced by the elastic ring and the outer ring, thereby avoiding damage to the circuit board due to installation.

The buffer component enables the skateboard 2 to move. At this time, the two opposite skateboards 2 are close to each other, and a circuit board 3 is placed on the top of the skateboard 2, wherein an identity recognition module in the prior art is arranged inside the circuit board 3. Two opposing slides 4 are arranged on the top of the circuit board 3, and the two slides 4 correspond to the two skateboards 2 one by one. Two vertical rods 5 are fixed to the bottom surface of the slide 4, and two side panels 6 are fixed to the outer side surface of the skateboard 2. The two vertical rods 5 correspond to the two side panels 6 one by one, and the bottom ends of the vertical rods 5 correspond to the outer ends of the side panels 6. Nuts 7 are spirally sleeved on the bottom ends of the vertical rods 5, and the top surfaces of the nuts 7 fit with the bottom surfaces of the side panels 6. At this time, the skateboard 2 and the slide 4 cooperate to limit the circuit board 3, and a ring block 8 is fixed at the center of the vertical rods 5, and the top surfaces of the side panels 6 fit with the bottom surfaces of the side panels 6. A regulating component is arranged between the two opposing slides 4, and the circuit board 3 is limited by the regulating component. A plurality of heat dissipation grooves 9 are arranged at the center of the surface of the base 1, and the heat dissipation grooves 9 correspond to the circuit board 3. After the circuit board 3 is installed, and the bottom surface of the circuit board 3 does not contact the top surface of the base 1, the bottom surface of the circuit board 3 can dissipate heat quickly. After limiting the distance between the two slides 2 by the buffer component, the circuit board 3 is placed on the top surfaces of the two slides 2 accordingly. The vertical rod 5 at the bottom end of the slide 4 corresponds to the side panel 6. The bottom end of the vertical rod 5 passes through the outer end of the side panel 6. The nut 7 cooperates with the vertical rod 5 so that the ring block 8 is placed on the top surface of the side panel 6. The two slides 4 are limited by the regulating component. At this time, the two slides 4 cooperate with the two slides 2 to limit the circuit board 3, thereby ensuring the stability of the circuit board 3 during the installation process.

[0035] exist Figure 1 , Figure 2 and Figure 4 In the embodiment, the bottom surface of the slide plate 2 is provided with bottom blocks 10 on both sides, the top surface of the base 1 is provided with a slide groove corresponding to the bottom block 10, the buffer component includes two inner rods 11, the two inner rods 11 are respectively located inside the two slide grooves, the surface of the inner rod 11 is sleeved with a spring 12, one end of the spring 12 is connected to the outer side of the bottom block 10, and the other end of the spring 12 is connected to the outer end of the slide groove, the surface of the inner rod 11 is spirally sleeved with a limiting sleeve 13, and the outer side of the limiting sleeve 13 is in contact with the inner side of the bottom block 10. The limiting sleeve 13 on the surface of the inner rod 11 is twisted, and the spiral cooperation of the limiting sleeve 13 and the inner rod 11 makes the limiting sleeve 13 move on the surface of the inner rod 11, and the moving limiting sleeve 13 cooperates with the elastic force of the spring 12 to adjust the slide plate 2, so that the slide plate 2 can be conveniently moved on the top of the base 1, and the relative distance between the two slide plates 2 can be adjusted in real time according to the length of the circuit board 3.

[0036] Illustratively, when the rotating limiting sleeve 13 drives the bottom block 10 to squeeze the spring 12 on the surface of the inner rod 11, the distance between the two slides 2 increases, and the circuit board 3 is placed on the top surface of the base 1. At this time, the limiting sleeve 13 is twisted in the opposite direction, and the elastic force of the spring 12 passes through the bottom block 10 to make the slide 2 close to the circuit board 3, so that the circuit board 3 can be simply clamped and limited by the elastic force of the spring 12.

[0037] exist Figure 1 and Figure 5 In the embodiment, the regulating component includes two corresponding parallel rotating sleeves 14, a baffle 15 is fixed to the inner side of the top surface of the slide 4, the rotating sleeve 14 is located between the two baffles 15, two parallel sliding rods 16 are arranged on the top surface of the slide 4, through grooves 17 are arranged on both sides of the baffle 15, and the inner side ends of the sliding rods 16 correspond to the through grooves 17, and the end of the rotating sleeve 14 is spirally sleeved on the inner side ends of the sliding rods 16, and two opposite arc grooves 18 are arranged on the top surface of the slide 4, and the inner sides of the two arc grooves 18 are vertically inserted with rotating rods 19, and the outer side ends of the sliding rods 16 are sleeved on the surface of the rotating rods 19, and the rotating rotating sleeve 14 makes the two opposite sliding rods 16 approach or move away from each other. Since the top end of the rotating rod 19 limits the outer side of the sliding rod 16, when the rotating sleeve 14 rotates on the inner side end surfaces of the two sliding rods 16, the rotating rotating sleeve 14 makes the two opposite sliding rods 16 approach or move away from each other.

[0038] exist Figure 3 , Figure 5 and Figure 6 In the embodiment, a circular plate 20 is fixed at the bottom of the rotating rod 19, and the two rotating rods 19 correspond to the two vertical rods 5 one by one, and a rotating plate 21 is arranged between the rotating rod 19 and the vertical rod 5, one end of the rotating plate 21 is sleeved on the surface of the vertical rod 5, and the other end of the rotating plate 21 is sleeved on the surface of the rotating rod 19, the bottom surface of the rotating plate 21 is in contact with the top surface of the circular plate 20, and the top surface of the rotating plate 21 is in contact with the bottom surface of the slide 4, and the rotating rotating plate 21 drives the rotating rod 19 to slide inside the arc groove 18. When the two slide bars 16 approach each other, the slide bar 16 pulls the rotating rod 19 to slide inside the arc groove 18 during the movement process, and because the arc groove 18 corresponds to the limitation of the rotating rod 19, the moving slide bar 16 moves inside the through groove 17 at this time, and the moving rotating rod 19 drives the rotating sleeve 14 to move by the slide bar 16, and the distance between the two rotating sleeves 14 increases at this time, and the rotating rod 19 drives the circular plate 20 to move synchronously, and at this time the circular plate 20 gradually approaches the end surface of the circuit board 3. When the two slide bars 16 approach each other, the slide bars 16 push the rotating rod 19 to slide inside the arc groove 18 during the movement. Since the arc groove 18 corresponds to the limitation of the rotating rod 19, the moving slide bar 16 moves inside the through groove 17 at this time, and the moving rotating rod 19 drives the rotating sleeve 14 to move by the slide bar 16. At this time, the distance between the two rotating sleeves 14 is reduced. At this time, the rotating rod 19 drives the circular plate 20 to move synchronously, and the circular plate 20 gradually moves away from the end face of the circuit board 3.

[0039] exist Figure 3 , Figures 5 to 9 In the figure, an outer ring 22 is arranged on the outside of the circular plate 20, and the outer side surface of the outer ring 22 is in contact with the end surface of the circuit board 3. The outer ring 22 is made of rubber material, and a plurality of plug rods 23 are fixed on the inner side surface of the outer ring 22. An elastic ring is arranged between the circular plate 20 and the outer ring 22, and the elastic ring is placed on the top of the plurality of plug rods 23. A pressure plate 24 is fixed on the inner end of the plug rod 23. An inner groove corresponding to the pressure plate 24 is arranged inside the circular plate 20, and the inner end of the plug rod 23 is located inside the inner groove. The rotating circular plate 20 drives the outer ring 22 to rotate by using the plug rod 23. The moving circular plate 20 drives the outer ring 22 to contact the end face of the circuit board 3. The reaction force of the end face of the circuit board 3 on the outer ring 22 causes the outer ring 22 to deform, and the outer ring 22 cooperates with the circular plate 20 to squeeze the elastic ring. The deformed outer ring 22 uses the insertion rod 23 to drive the pressure plate 24 to move. The squeezing force of the circular plate 20 on the end face of the circuit board 3 is reduced through the elastic ring and the outer ring 22, thereby avoiding damage to the circuit board 3 due to installation.

[0040] When the reverse rotating sleeve 14 uses the slide rod 16 to make the rotating rod 19 move away from the baffle 15, when the moving rotating rod 19 is at the end of the arc groove 18, the rotating sleeve 14 continues to rotate in the reverse direction. At this time, the slide rod 16 uses the rotating rod 19 to push the slide 4 to move. At this time, the two slides 4 are separated from each other, and the slide 4 uses the vertical rod 5 and the side plate 6 to drive the slide plate 2 to move synchronously. At this time, the two slide plates 2 are away from each other. During the movement, the slide plate 2 uses the bottom block 10 to squeeze the spring 12 on the surface of the inner rod 11. At this time, the circuit board 3 can be quickly taken out from between the slide plate 2 and the slide 4, and the circuit board 3 can be quickly replaced.

[0041] exist Figure 8 and Fig. 9 In the embodiment, two side bars 25 are arranged inside the inner groove, and the two ends of the pressure plate 24 are respectively sleeved on the surfaces of the two side bars 25. A pressure bar 26 is vertically inserted at the bottom of the inner groove, and a connecting plate 27 is arranged inside the inner groove. The top end of the connecting plate 27 is hinged to the inner side of the pressure plate 24, and the bottom end of the connecting plate 27 is hinged to the top end of the pressure bar 26. A bottom plate 28 is fixed to the bottom end of the pressure bar 26, and the bottom surface of the bottom plate 28 corresponds to the top surface of the slide plate 2, and the bottom plate 28 is made of rubber material. When the circular plate 20 uses the outer ring 22 to squeeze the end face of the circuit board 3, the deformed outer ring 22 uses the insertion rod 23 to drive the pressure plate 24 to move, and the moving pressure plate 24 slides on the surface of the side rod 25, and the moving pressure plate 24 drives the top end of the connecting plate 27 to move. Since the pressure plate 24 cooperates to limit the top end of the connecting plate 27, the connecting plate 27 rotates under the drive of the pressure plate 24, and the bottom end of the rotating connecting plate 27 pushes the pressure rod 26 to move downward. The downward pressure rod 26 uses the bottom film 28 to squeeze the top surface of the slide plate 2, and the circular plate 20 is limited by the extrusion force of the bottom film 28 and the slide plate 2. Multiple circular plates 20 use the outer ring 22 outside the elastic ring to limit the circuit board 3, thereby improving the stability of the installation of the circuit board 3.

[0042] The present invention also provides a PCB circuit board preparation process, referring to Figures 1 to 9 As shown, the circuit board structure applied to the PCB circuit board as described above includes the following steps:

[0043] S1, twist the limiting sleeve 13 on the surface of the inner rod 11, the limiting sleeve 13 and the inner rod 11 are spirally matched to make the limiting sleeve 13 move on the surface of the inner rod 11, and the moving limiting sleeve 13 and the elastic force of the spring 12 cooperate to adjust the slide plate 2, so that the slide plate 2 can move on the top of the base 1 conveniently, and the relative distance between the two slide plates 2 is adjusted in real time according to the length of the circuit board 3, and the circuit board 3 is placed on the top surface of the two slide plates 2 accordingly;

[0044] S2, the vertical rod 5 at the bottom end of the slide 4 corresponds to the side plate 6, the bottom end of the vertical rod 5 passes through the outer end of the side plate 6, the nut 7 cooperates with the vertical rod 5 so that the ring block 8 is placed on the top surface of the side plate 6, and the two rotating sleeves 14 are placed between the two baffles 15, and the end of the rotating sleeve 14 is spirally sleeved on the inner end of the slide rod 16;

[0045] S3, twist the rotating sleeve 14. Since the rotating plate 21 limits the outer end of the slide bar 16 through the rotating rod 19, the rotating sleeve 14 rotates on the inner end surface of the slide bar 16. The rotating rotating sleeve 14 makes the two opposite slide bars 16 approach each other. The moving slide bar 16 pulls the rotating rod 19 to slide inside the arc groove 18, and the moving rotating rod 19 drives the rotating plate 21 to rotate. The moving rotating rod 19 drives the outer ring 22 to squeeze the end surface of the circuit board 3 using the circular plate 20.

[0046] S4. The reaction force of the end face of the circuit board 3 on the outer ring 22 causes the outer ring 22 to deform, and the outer ring 22 cooperates with the circular plate 20 to extrude the elastic ring. The deformed outer ring 22 uses the insertion rod 23 to drive the pressure plate 24 to move. The moving pressure plate 24 slides on the surface of the side rod 25, and the moving pressure plate 24 drives the top of the connecting plate 27 to move. Since the pressure plate 24 cooperates to limit the top of the connecting plate 27, the connecting plate 27 rotates under the drive of the pressure plate 24. The bottom end of the rotating connecting plate 27 pushes the pressure rod 26 to move downward. The downward pressure rod 26 uses the bottom film 28 to extrude the top surface of the slide plate 2. The circular plate 20 is limited by the extrusion force of the bottom film 28 and the slide plate 2. Multiple circular plates 20 use the outer ring 22 on the outside of the elastic ring to limit the circuit board 3, thereby improving the stability of the installation of the circuit board 3.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
