[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: The intelligent suspension conveying device for PC board production can release the limit on the suspension plate by disengaging the limit plate from the suspension groove, thereby preventing the suspension plate from being lifted at will due to misoperation or external interference, thereby reducing the risk of accidental dropping of the PC board, thereby reducing the downtime of the suspension conveying line and improving the continuity and efficiency of the PC board suspension conveying. The extrusion plate moves upward to contact the reserved hole of the PC board and squeezes and fixes the PC board, thereby reducing the displacement and shaking of the PC board during suspension conveying. By reducing the additional vibration load caused by the shaking, the abnormal wear of core components such as chains and guide rails can be reduced, and the probability of sudden failures can be reduced, thereby improving the stability of the PC board suspension conveying.

[0016] The intelligent suspended conveying device for PC board production drives the partition frame to move downward by moving the connecting plate downward.

[0017] (3) The intelligent hanging conveying device for PC board production drives the partition frame to move upward by moving the connecting plate upward. The partition frame moves upward to break away from the contact with multiple PC boards, thereby facilitating the unloading of multiple partition frames. When the partition frame moves upward and breaks away from the PC board, it can eliminate the obstruction to the PC board, so that the PC board can be unloaded quickly and smoothly, further improving the overall hanging conveying efficiency.

[0018] (4) The intelligent suspension conveying device for PC board production prevents the gas inside the sleeve rod from being discharged through the air guide hole, which makes the guide rod unable to move vertically. The guide rod cannot move vertically, which makes the lifting shaft unable to move vertically to lift the PC board. The lifting shaft cannot move, which ensures that the PC board maintains a fixed height during the suspension process, avoids the position of the PC board being shifted due to accidental movement of the lifting shaft, and effectively protects the accuracy of the placement of the PC board.

[0019] (5) The intelligent suspension conveying device for PC board production allows the gas inside the sleeve rod to be slowly discharged through the air guide holes so that the lifting shaft can only move slowly to lift the PC board. The design of slowly discharging the gas inside the sleeve rod through the air guide holes to achieve slow movement of the lifting shaft provides buffer protection for the lifting process of the PC board, thereby preventing the PC board from colliding violently with the ground or other components when the lifting shaft descends rapidly, thereby avoiding safety accidents caused by excessive speed.

Detailed Embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Please refer to Figures 1-6, the present invention provides a technical solution: an intelligent suspension conveying device for PC board production, including a guide rail 1 and a conveying component, and further including a suspension module, a separation module and a protection module. The conveying component is arranged at the bottom of the guide rail 1. The suspension module includes a lifting table 2, a lifting shaft 3, a suspension frame 4, a suspension rod 5, a suspension plate 6, a suspension groove 7, a limit disk 8, a pressing column 9, a pressing plate 10, a suspension spring 11 and a limit groove 1401. The lifting table 2 is fixedly installed on the conveying equipment component. The lifting shaft 3 is arranged inside the lifting table 2. The suspension frame 4 is fixedly installed at the bottom of the lifting shaft 3. The suspension rod 5 is fixedly installed inside the suspension frame 4. The suspension plate 6 slides through the top of the right side of the suspension frame 4. The suspension groove 7 is opened on the front side of the suspension plate 6. The limit disk 8 is rotatably installed on the top of the suspension frame 4. The pressing column 9 slides inside the suspension rod 5. The pressing plate 10 slides through the circumferential surface of the suspension rod 5. The suspension spring 11 is arranged between the lifting shaft 3 and the suspension plate 6. The limit groove 1401 is opened on the top of the limit disk 8. A first spring is arranged between the suspension rod 5 and the pressing column 9. A second spring is arranged between the suspension rod 5 and the pressing plate 10. The inside of the suspension rod 5 is filled with liquid. The pressing plate 10 is elastic. By reducing the additional vibration load caused by shaking, abnormal wear of core components such as chains and guide rails 1 can be reduced, and the probability of sudden failures can be lowered, thereby improving the stability of PC board suspension conveying. The suspension height of the PC board can be adjusted through the lifting table 2 and the lifting shaft 3.

[0025] The suspension plate 6 contacts the suspension rod 5, and the suspension plate 6 abuts against the pressing column 9. The right side of the pressing column 9 is set as an inclined surface. A torsion spring is arranged between the suspension frame 4 and the limit disk 8. When the limit disk 8 rotates, it squeezes the torsion spring. The torsion spring deforms and stores energy under the extrusion of the limit disk 8. After the limit groove 1401 disengages from the contact with the suspension plate 6, the limit disk 8 can be driven to reset by the torsion spring. The pressing column 9 can be supported by the first spring, and the pressing plate 10 can be supported by the second spring.

[0026] The limit disk 8 contacts the inner wall of the suspension groove 7. A first rubber ring is arranged between the suspension rod 5 and the pressing column 9. The sealing performance between the suspension rod 5 and the pressing column 9 can be increased through the first rubber ring. A second rubber ring is arranged between the suspension rod 5 and the pressing plate 10. The sealing performance between the suspension rod 5 and the pressing plate 10 can be increased through the second rubber ring. When the limit disk 8 rotates to align the limit groove 1401 with the suspension groove 7, the limit disk 8 disengages from the contact with the suspension groove 7 and releases the limit on the suspension plate 6, avoiding the random lifting of the suspension plate 6 caused by misoperation or external interference, thereby reducing the risk of accidental dropping of the PC board, reducing the downtime of the suspension conveying line, and improving the continuity and efficiency of PC board suspension conveying.

[0027] During operation, the operator rotates the limit plate 8. When the limit plate 8 rotates so that the limit slot 1401 is aligned with the suspension slot 7, the limit plate 8 breaks away from the contact with the suspension slot 7 and releases the limit on the suspension plate 6. At the same time, the limit plate 8 rotates to squeeze the torsion spring. The torsion spring is squeezed by the limit plate 8 to produce deformation and accumulate force. After the limit of the suspension plate 6 is released, the operator pulls the suspension plate 6 to move upward. The suspension plate 6 moves upward to pull the suspension spring 11. The suspension spring 11 is pulled by the suspension plate 6 to produce The suspension plate 6 is deformed and accumulates force, and at the same time, the suspension plate 6 moves upward to break away from the contact with the suspension rod 5. After the suspension rod 5 breaks away from the contact with the suspension plate 6, the operator hangs multiple PC boards with reserved holes on the circumferential surface of the suspension rod 5. After multiple PC boards are hung to the specified position, the operator repeats the operation to rotate the limit plate 8. When the limit plate 8 rotates so that the limit groove 1401 is aligned with the suspension groove 7 at the bottom of the suspension plate 6, the limit plate 8 breaks away from the contact with the suspension groove 7 at the bottom of the suspension plate 6 and releases the limit on the suspension plate 6. After the limit of the hanging plate 6 is released, the hanging plate 6 moves downward and resets under the elastic force of the hanging spring 11, and the hanging plate 6 moves downward and resets to contact the inclined surface on the right side of the extrusion column 9 and squeeze the extrusion column 9. The extrusion column 9 is squeezed to the left by the hanging plate 6, and the extrusion column 9 moves to the left to squeeze the spring 1. The spring 1 is squeezed by the extrusion column 9 to produce deformation and accumulate force. At the same time, the extrusion column 9 moves to the left to squeeze the liquid inside the hanging rod 5. The liquid inside the hanging rod 5 is squeezed by the extrusion column 9 to apply extrusion force to the extrusion plate 10. The extrusion plate 10 is squeezed by the liquid inside the hanging rod 5 and moves upward. The extrusion plate 10 moves upward to pull the spring 2. The spring 2 is pulled by the extrusion plate 10 to produce deformation and accumulate force. At the same time, the extrusion plate 10 moves upward to contact the reserved hole of the PC board and squeeze and fix the PC board, thereby reducing the displacement and shaking of the PC board during suspension and transportation. After the PC board is suspended stably, the conveying assembly cooperates with the lifting platform 2 to suspend and transport the PC board.

The partition frame 124 moves downward to separate multiple PC boards.

[0030] The separation module also includes a connecting plate 125, a separation spring 126 and a stop ring 127. The connecting plate 125 is fixedly installed on the right side of the separation frame 124. The separation spring 126 is arranged between the lifting shaft 3 and the connecting plate 125. The connecting plate 125 moves upward to pull the separation spring 126. The separation spring 126 is deformed and accumulates force due to the pulling of the connecting plate 125. After the connecting plate 125 is separated from the contact with the suspension plate 6, the connecting plate 125 can be driven to reset by the separation spring 126. The stop ring 127 is fixedly installed on the circumferential surface of the separation rod 122. The connecting plate 125 moves downward to drive the separation frame 124 to move downward. A physical isolation barrier is formed through the separation frame 124. Even when the conveying component is started, stopped or accelerated, the PC boards can be prevented from being squeezed against each other due to inertia, thereby effectively protecting the integrity of the PC board surface and reducing the defective rate caused by surface scratches and corner bumps.

[0031] The connecting plate 125 is in contact with the suspension plate 6, the stop ring 127 is elastic, the connecting plate 123 is in contact with the bottom of the inner wall of the lifting shaft 3, the connecting plate 125 moves upward to drive the partition frame 124 to move upward, and the partition frame 124 moves upward to break away from the contact with multiple PC boards, thereby facilitating the unloading of multiple partition frames 124. When the partition frame 124 moves upward and breaks away from the PC board, it can eliminate its obstruction to the PC board, so that the PC board can be unloaded quickly and smoothly, further improving the overall suspension conveying efficiency.

[0033] The protection module also includes an elastic telescopic rod 134, a rubber block 135 and an air guide hole 136. The elastic telescopic rod 134 is fixedly installed on the left side of the hollow block 133, the rubber block 135 is fixedly installed on the left side of the hollow block 133, and the air guide hole 136 is opened on the circumferential surface of the sleeve rod 131. The lifting shaft 3 cannot move, which can ensure that the PC board maintains a fixed height during the suspension process, avoids the position of the PC board being offset due to accidental movement of the lifting shaft 3, and effectively protects the accuracy of the placement of the PC board. The hollow block 133 can be reset by the elastic telescopic rod 134.

[0034] A third spring is provided between the sleeve rod 131 and the guide rod 132. The guide rod 132 can be supported by the third spring. A third rubber ring is provided between the sleeve rod 131 and the guide rod 132. The sealing performance between the sleeve rod 131 and the guide rod 132 can be improved through the third rubber ring. The right bottom of the hollow block 133 is provided as an inclined surface. The hollow block 133 contacts with the connecting plate 123. The slow-speed movement design of the lifting shaft 3 is realized by the slow discharge of the gas in the sleeve rod 131 through the air guide hole 136, providing buffer protection for the lifting process of the PC board and thus avoiding safety accidents caused by too fast speed.

[0035] During operation, the suspension plate 6 moves upward to contact with the connection plate 125 and extrude the connection plate 125. The connection plate 125 moves upward under the extrusion of the suspension plate 6. The upward movement of the connection plate 125 drives the partition frame 124 to move upward. The upward movement of the partition frame 124 drives the connecting plate 123 to move upward. After the PC board is stably suspended, the suspension plate 6 moves downward to reset under the elastic force of the suspension spring 11. The suspension plate 6 moves downward to reset and disengages from the contact with the connection plate 125. After the connection plate 125 disengages from the contact with the suspension plate 6, the connection plate 125 moves downward to reset under the elastic force of the partition spring 126. The downward movement of the connection plate 125 drives the partition frame 124 to move downward. The partition frame 124 moves downward to separate multiple PC boards. After multiple PC boards are transported to the designated position, the operator repeats the operation of pulling the suspension plate 6 upward to contact with the connection plate 125 and extrude the connection plate 125. The connection plate 125 moves upward under the extrusion of the suspension plate 6. The upward movement of the connection plate 125 drives the partition frame 124 to move upward. The partition frame 124 moves upward to disengage from the contact with multiple PC boards, thus facilitating the blanking of multiple partition frames 124.

[0036] The connecting plate 123 moves upward and contacts the inclined surface of the hollow block 133 and squeezes the hollow block 133. The hollow block 133 is squeezed to the left by the connecting plate 123. The hollow block 133 moves to the left, driving the elastic telescopic rod 134 to move to the left. The elastic telescopic rod 134 moves to the left, contacts the inner wall of the lifting shaft 3 and squeezes the inner wall of the lifting shaft 3. The free end of the elastic telescopic rod 134 is squeezed by the reaction force of the lifting shaft 3 and retracts and accumulates force. At the same time, the hollow block 133 moves to the left, driving the rubber block 135 to move to the left. The rubber block 135 The guide plate 125 moves to the left side to contact with the air guide hole 136 and seal the air guide hole 136. The air guide hole 136 is sealed by the rubber block 135 so that the gas inside the sleeve rod 131 cannot be discharged through the air guide hole 136. The gas inside the sleeve rod 131 cannot be discharged through the air guide hole 136, so that the guide rod 132 cannot move vertically. The guide rod 132 cannot move vertically, so that the lifting shaft 3 cannot move vertically to lift the PC board. After the PC board is suspended stably, the connecting plate 125 moves downward and resets under the elastic force of the separation spring 126, and the connecting plate 125 is The partition frame 124 moves downward, and the partition frame 124 moves downward, and the connection plate 123 moves downward and resets. The connection plate 123 moves downward and resets to break away from the contact with the hollow block 133. After the hollow block 133 breaks away from the contact with the connection plate 123, the elastic telescopic rod 134 moves to the right side and resets under the action of its own elastic force. The elastic telescopic rod 134 moves to the right side and resets, and the hollow block 133 is reset. The reset of the hollow block 133 drives the rubber block 135 to move to the right side and break away from the contact with the air guide hole 136. The rubber block 135 moves to the right side. Move out of contact with the air guide hole 136 and release the seal on the sleeve rod 131. After the seal of the sleeve rod 131 is released, the lifting shaft 3 moves vertically upward to drive the sleeve rod 131 to move vertically upward. The sleeve rod 131 moves vertically upward so that the guide rod 132 squeezes the gas inside the sleeve rod 131. The gas inside the sleeve rod 131 is squeezed by the guide rod 132 and slowly discharged through the air guide hole 136. The gas inside the sleeve rod 131 is slowly discharged through the air guide hole 136, so that the lifting shaft 3 can only move slowly to lift the PC board.
