[0031] Embodiment 1

[0032] Please refer to Figures 1-10 The embodiment of the application provides a PC board production carrying device, which relates to the technical field of conveying devices. The device comprises a transfer workboard 1, a first sliding rail 2, a second sliding rail 11, a sliding workboard 4, a carrier 7, a support connector 6, the first sliding rail 2 and the second sliding rail 11 are connected to the upper surface of the transfer workboard 1 in parallel and at intervals, the two sides of the lower surface of the sliding workboard 4 are slidably connected with the first sliding rail 2 and the second sliding rail 11, the carrier 7 is connected to the middle part of the sliding workboard 4, two support connectors 6 are connected to the two sides of the sliding workboard 4, the top of the carrier 7 is connected with an elastic work cylinder 19, and the top of the elastic work cylinder 19 and the support connector 6 are in contact with the PC board.

[0033] It should be noted that the prior art mostly uses simple side trolleys to realize the conversion of the PC board station, which can save time and effort to a certain extent, but this method does not reserve elastic space for the PC board, which has many disadvantages in this process: (1) The vibration frequency of the station transfer trolley is 8-15Hz and 20-30Hz, which overlaps with the inherent frequency of the PC board (15-25Hz). Experimental data shows that the internal stress fluctuation amplitude of the board without buffer reaches 18% of the material yield strength after 2 hours of continuous transfer. A certain electronic factory measured that the incidence of micro-cracks in the solder joints of rigidly fixed PCB substrates increased by 2.7 times after trolley transportation, directly leading to a 1.2% decrease in the yield rate of the subsequent process; (2) The inertial force generated by the acceleration and deceleration (0.5-1.5m / s 2 ) of the trolley causes the board to bear dynamic bending moment. Finite element simulation shows that the stress concentration coefficient at the fixed point of the rigidly clamped board is 3.8 when it is suddenly stopped, and the maximum principal stress is 122MPa. Data shows that the surface stress-induced birefringence phenomenon of the optical-grade PC board without buffer after trolley transportation reduces the uniformity of light transmittance by 2.8%; (3) The collision frequency between the trolley and obstacles in the narrow passageway of the workshop reaches 3-5 times / hour. Measured data shows that the edge wear depth of the board without elastic spacing after collision is 0.1-0.3mm, and the surface scratch density increases by 6 scratches / cm2. A certain automobile parts factory statistics shows that the optical performance defects caused by surface damage of the PC board without buffer packaging account for 32% of the total defects in the station transfer; (4) The subcritical cracks generated by multiple transfers (>10 times / batch) increase the probability of expansion in subsequent processing by 300%. A display panel manufacturer found that the adhesion of the film layer of the board without buffer transfer after plating decreased by 22%, and the yield rate decreased by 3.1%. This delayed damage will cause the after-sales failure rate to rise by 55% after 3-6 months.

[0034] The embodiment is provided with a transfer workboard 1, a first sliding rail 2, a second sliding rail 11, a sliding workboard 4, a carrier 7, a support connector 6, and an elastic work cylinder 19. The transfer workboard 1 is used to position the entire carrying track. The carrier 7 and the support connector 6 are used to contact and elastically support the PC board. The sliding workboard 4 is used to connect the carrier 7 and the support connector 6. The first sliding rail 2 and the second sliding rail 11 are used to reduce the resistance of the sliding workboard 4 during transportation and improve the carrying efficiency. In detail, the elastic work cylinder 19 is arranged on the top of the carrier 7. The elastic work cylinder 19 is used to reserve elastic space for the PC board during the transfer process, reduce the vibration transmission rate of the PC board to below 0.3, effectively suppress the resonance effect, extend the impact response time to 80 ms, reduce the stress peak value by 45%, reduce the relative displacement between the boards, absorb the collision kinetic energy, effectively avoid the increase of internal cracks and the shortening of fatigue life of the PC board during the transfer process, effectively reduce the loss of the PC board, and solve the problem of the increase of internal micro-cracks and the reduction of service life of the PC board caused by the simple tool transfer in the prior art, and the reduction of the quality of the PC board.

A work support column 5 is connected between the support connector 6 and the sliding workboard 4. The first lifting column 14, the second lifting column 15, and the third lifting column 8 are movably connected to the top of the work support column 5, and the support connector 6 is connected to the top of the first lifting column 14, the second lifting column 15, and the third lifting column 8. The first sliding rail 2 and the matching rack 10, and the second sliding rail 11 and the matching rack 10 are both connected with an elastic work section 16.

[0036] Embodiment 2

[0037] The embodiment of the application provides a PC board production carrying device, and relates to the technical field of conveying devices.The device comprises a transfer work plate 1, a first sliding rail 2, a second sliding rail 11, a sliding work plate 4, a carrier 7, a support connector 6, the first sliding rail 2 and the second sliding rail 11 are connected to the upper surface of the transfer work plate 1 in parallel and at intervals, the lower surface of the sliding work plate 4 is slidably connected to the first sliding rail 2 and the second sliding rail 11, the carrier 7 is connected to the middle part of the sliding work plate 4, two support connectors 6 are connected to the two sides of the sliding work plate 4, the top of the carrier 7 is connected with an elastic work cylinder 19, and the top of the elastic work cylinder 19 and the top of the support connector 6 are in contact with the PC board. A matching rack 10 is connected between the first sliding rail 2 and the second sliding rail 11, and a rotating work disc 3 engaged with the matching rack 10 is connected to the lower surface of the sliding work plate 4. Through the matching rack 10 and the rotating work disc 3, the rotating work disc 3 is moved on the matching rack 10 to realize the carrying of the PC board to different work stations. Further, the lower surface of the sliding work plate 4 is also connected with a sliding block, the sliding block slides on the first sliding rail 2 and the second sliding rail 11, provides support force for the two sides of the sliding work plate 4, reduces friction, and improves carrying efficiency.

[0038] In some embodiments, the support connector 6 is provided with a placing groove 9 for placing the PC board, and the support connector 6 is connected with a work handle 12. Through the placing groove 9, the two sides of the PC board are in contact with the placing groove 9, and the middle part is in contact with the elastic work cylinder 19. Through the work handle 12, the height of the support connector 6 can be adjusted.

[0039] In some embodiments, a work support column 5 is connected between the support connector 6 and the sliding work plate 4. The work support column 5 is a lifting column, and can adjust the height of the two sides of the PC board.

[0040] In some embodiments, the top of the work support column 5 is movably connected with a first lifting column 14, a second lifting column 15 and a third lifting column 8, and the top of the first lifting column 14, the second lifting column 15 and the third lifting column 8 is connected with the support connector 6. The first lifting column 14, the second lifting column 15 and the third lifting column 8 realize stable lifting and play a role in stable support. In detail, as shown in Figure 10 Due to different impact resistances of the carrier 7 under different quality actions, when the top of the two work support columns 5 is lifted, the elastic work cylinder 19 is popped up to a specified height, and when the quality of the PC board reaches a specified threshold, the elastic work cylinder 19 is popped up to the specified height again, so that the elastic space is effectively increased.

[0041] In some embodiments, the first slide rail 2 and the mating rack 10, and the second slide rail 11 and the mating rack 10 are connected with elastic working sections 16. The elastic working sections 16 can reduce the vibration of the PC board during transportation, and further reduce the generation of micro-cracks in the PC board.

[0042] In some embodiments, the elastic working section 16 at least includes several elastic air bags. It should be noted that in the prior art, the PC board is transported by a transfer trolley. When the transfer trolley vibrates at a frequency of 2-4 Hz, the stacked PC board (≥8 layers) without buffering will be amplified by 4.7 times. Research data shows that the probability of molecular chain rupture under this working condition is 17 times higher than that of single-layer transportation. In addition, the temperature difference (ΔT≥8℃) between the workstations causes the linear expansion of the PC board ΔL=α·L·ΔT (α=6.8×10^-5 / ℃). Under the condition of rigid constraint, 5.4 mm displacement is generated per meter length, which causes 36 MPa internal stress, which is 240% of the material yield strength. In addition, research has shown that when the PC board experiences a temperature change rate of more than 5℃ / min without buffering, the proportion of amorphous region decreases by 12%, which reduces the anti-creep performance by 23%. In addition, the transfer trolley needs to be operated by manual area during use. The impact force generated by a 0.3 m drop height (E=mgh=1.2 J) during manual transportation will form a transient load of 130 N under the condition of no buffering. Research institute test shows that this value is 1.7 times the dynamic yield strength of the PC board. In addition, plastic turnover boxes are placed on the transfer trolley, but when the plastic turnover boxes are in direct contact with the PC board, the surface static voltage can reach 35 kV, which increases the dust adsorption amount by 300%. Research by the China Institute of Metrology shows that this will increase the surface roughness Ra value from 0.2 μm to 0.7 μm. The elastic air bag provided in the embodiment provides elastic buffering for PC board handling, and realizes different degrees of shock absorption. By controlling the size of the elastic air bag expansion, the shock absorption of PC boards of different masses during transportation is realized.

[0043] It should be noted that by setting the elastic air bag, at least 1.2 J of impact energy generated during handling and loading and unloading can be absorbed, so that the effective contact force is reduced from 130 N to 45 N (65% reduction), which is lower than the PC board surface yield threshold (50 N). Preferably, the outer surface of the elastic air bag is coated with carbon fiber composite material, which can reduce the static accumulation voltage from 35 kV to 0.5 kV, reduce the dust adsorption amount by 98%, and reduce the PC board cleaning cost by 83%. The elastic space provided by the elastic air bag and the elastic working cylinder 19 can reduce the single transfer damage degree from 3×10^-5 to 8×10^-6, and the fatigue life can be increased from 35,000 times to 130,000 cycles, an increase of 271%.

[0044] Preferably, the elastic air bag and the elastic working cylinder 19 are provided with a conductive protective layer, and the surface resistivity of the conductive protective layer is 106-108Ω·m.

[0045] Optionally, the elastic working section 16 can be a gradient density buffer layer, and the frequency selective attenuation is realized by a gradient polyurethane layer, and the attenuation rate of 5-7Hz vibration is 82%.

[0046] Optionally, the elastic working section 16 can be a two-stage vibration isolation system composed of an air spring and a silica gel pad. The air pressure of the air spring is monitored in real time by a pressure sensor and dynamically adjusted by a proportional valve. Specifically, the first-stage vibration isolation is realized by four groups of air springs, the working pressure is 0.5-0.8MPa, the natural frequency is 2-5Hz, and low-frequency vibrations can be absorbed. The second-stage vibration isolation is an elastic pad made of silica gel composite material with a Shore hardness of 50A and a thickness of 10mm, and the damping ratio is 0.3-0.5. The accuracy of the air pressure sensor is ±0.01MPa, which is used to monitor the air spring pressure in real time, and the air pressure is dynamically adjusted by a proportional valve with a response time of 50ms. Through the synergistic effect of the air spring and the silica gel pad, wide frequency domain vibration suppression is realized, and the effective value (RMS) of the vibration acceleration is controlled below 0.5G.

[0047] In some embodiments, magnetic strips 17 are connected between the first sliding rail 2 and the transfer workboard 1 and between the second sliding rail 11 and the transfer workboard 1. The first sliding rail 2 and the transfer workboard 1 are magnetically connected, and the second sliding rail 11 and the transfer workboard 1 are magnetically connected.

[0048] In some embodiments, the transfer workboard 1 is connected with a first fixed footrest 13 and a second fixed footrest 18, the first fixed footrest 13 and the second fixed footrest 18 are respectively located at both ends of the matching rack 10 and are spaced apart from the matching rack 10, the first fixed footrest 13 is connected with a first distance meter 20, the second fixed footrest 18 is connected with a second distance meter 21, and the first distance meter 20 and the second distance meter 21 are connected with the elastic air bag signal. The first distance meter 20 and the second distance meter 21 detect the position change of the carrier 7, send the position signal to the remote control end, and control the elastic air bag to expand to a specified size.

[0049] In some embodiments, the rotating work disc 3 is connected with a gear 22, the matching rack 10 includes a tooth seat 23 and a tooth 24 connected to the tooth seat 23, and the tooth 24 is engaged with the gear 22.

[0050] It should be noted that the PC board production conveying device provided by the embodiment can reduce the vibration transmission rate from 0.85 to 0.32, reduce the stress peak value from 125 MPa to 82 MPa, shorten the single transfer time from 90 seconds to 65 seconds, increase the daily processing capacity by 38%, and improve the yield rate from 91.2% to 97.8%, thereby saving about 12 million yuan per year.

It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
