[0013] By adjusting the effective number of turns of the shock-absorbing spring, the shock-absorbing capacity of the shock-absorbing spring on the material tray can be adjusted to meet different usage occasions.

Since the extension plates on both sides are respectively inserted into the shock absorbing springs between the adjacent turns, and the adjustment plate and the transmission shaft are spline-connected, the extension plates move downward while rotating, so that the effective turns of the shock absorbing spring between the buffer plate and the extension plate increase, and the shock absorbing capacity of the shock absorbing spring becomes stronger. At the same time, the adjustment plate drives the buffer shaft to move downward, and the ratchet teeth on the buffer shaft follow and move downward; When the extension plate moves to the set position, the displacement sensor on the extension plate feeds back the displacement data to the control system, and the control system energizes the electromagnet, which is a push-pull electromagnet.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The buffer plate can reduce the shock and buffer the tray to improve the stability of the tray.

The shock-absorbing spring can buffer the impact force of the tray to prevent the tray from being damaged or the parts on the tray from splashing, and improve the stability of the tray. By adjusting the effective number of turns of the shock-absorbing spring, the shock-absorbing capacity of the tray can be adjusted to meet different usage occasions. The more effective turns of the shock-absorbing spring, the stronger the shock-absorbing capacity of the shock-absorbing spring.

[0017] 2. Dust removal on the tray to prevent dust from having adverse effects on the tray. The control system opens the solenoid valve in the dust removal chamber and the air slip ring inlet connection pipe, and the negative pressure system draws the air in the dust removal chamber outward, so that the dust around the tray enters the dust removal chamber through the adsorption hole, and is discharged to the outside atmosphere through the dust removal chamber, pipe and air slip ring, preventing the tray from being contaminated with dust during transportation, which may cause problems such as slow transportation and obstruction, and avoid dust from having adverse effects on the parts in the tray.

[0018] 3. The tray is automatically centered to prevent it from shifting. The control system controls the telescopic cylinders on both sides to work and the coils to access the circuit. The coils generate a magnetic field to change the magnetorheological fluid from liquid to solid. The telescopic cylinders on both sides drive the sliding plates on both sides to move relative to each other, so that the distance between the sliding plates on both sides becomes smaller. The sliding plates on both sides drive the conveyor belts and the carrier plates on both sides to move relative to each other. The carrier plates on both sides clamp and position the tray to keep it centered and prevent it from shifting. The magnetorheological fluid changes from liquid to solid, preventing the conveyor belt from bending and deforming during the clamping process, which can further improve the clamping effect of the carrier plate.

The multiple sets of positioning cylinders 161 are connected to the negative pressure system. A proximity switch is installed on the tray seats 16, and the proximity switch is electrically connected to the control system.

[0026] The feeding track includes a feeding motor 18 and a feeding guide rail 181. The feeding guide rail 181 is installed on the frame 11. Feeding rollers are rotatably installed at both ends of the feeding guide rail 181. A slider 182 is slidably installed on the feeding guide rail 181. The output shaft of the feeding motor 18 is connected to one of the feeding rollers. The feeding motor 18 is installed on the feeding guide rail 181. A transmission belt 183 is sleeved between the two groups of feeding rollers. The slider 182 is connected to the transmission belt 183. A support plate 184 is installed on the slider 182; a buffer plate 185 is installed above the support plate 184, and multiple groups of guide columns are arranged on the buffer plate 185. The multiple groups of guide columns pass through the support plate 184, and a sliding connection is formed between the guide columns and the support plate 184; An adjusting motor 19 is installed in the middle of the support plate 184. The output shaft of the adjusting motor 19 passes through the support plate 184 and is connected to a transmission shaft 191. An adjusting plate 192 is splined on the outer side of the transmission shaft 191. A shock absorbing spring 193 is installed on the outer side of the adjusting plate 192. Two groups of extension plates 194 are arranged on the outer side of the adjusting plate 192. One group of extension plates 194 is higher than the other group of extension plates 194. The two groups of extension plates 194 are respectively inserted between adjacent turns of the shock absorbing spring 193. The upper end of the shock-absorbing spring 193 is installed on the buffer plate 185, and another group of displacement sensors are installed on the two groups of extension plates 194; a buffer shaft 195 is arranged on the lower side of the adjustment plate 192, and the buffer shaft 195 passes through the support plate 184. The buffer shaft 195 is provided with a plurality of one-way ratchet teeth, and an electromagnet 196 is installed on the support plate 184 on one side of the buffer shaft 195, and a pawl 197 is installed on the telescopic rod of the electromagnet 196, and the pawl 197 and the ratchet teeth are adapted to each other.

[0027] By adjusting the effective number of turns of the shock absorbing spring 193, the shock absorbing capacity of the shock absorbing spring 193 on the material tray 17 can be adjusted to meet different usage occasions. The effective number of turns refers to the number of turns of the shock absorbing spring 193 between the buffer plate 185 and the extension plate 194. The more effective turns of the shock absorbing spring 193, the stronger the shock absorbing capacity of the shock absorbing spring 193. The control system drives the transmission shaft 191 to rotate by adjusting the motor 19, and the transmission shaft 191 drives the adjustment plate 192 to rotate, and the adjustment plate 192 drives the extension plates 194 on both sides to rotate accordingly. Since the extension plates 194 on both sides are respectively inserted into the damping spring 193 between adjacent turns, and the adjustment plate 192 and the transmission shaft 191 are spline-connected, the extension plate 194 moves downward while rotating, so that the effective number of turns of the damping spring 193 between the buffer plate 185 and the extension plate 194 increases, and the damping capacity of the damping spring 193 becomes stronger. At the same time, the adjustment plate 192 drives the buffer shaft 195 to move downward, and the ratchet teeth on the buffer shaft 195 follow and move downward; When the extension plate 194 moves to the set position, the displacement sensor on the extension plate 194 feeds back the displacement data to the control system, and the control system energizes the electromagnet 196. The electromagnet 196 is a push-pull electromagnet, and the telescopic rod is a reciprocating component on the electromagnet 196. The telescopic rod on the electromagnet 196 pushes the pawl 197 to engage with the ratchet teeth, so that the buffer shaft 195 cannot move downward, and the extension plate 194 and the adjustment plate 192 cannot move, thereby realizing the adjustment of the buffer shock absorption capacity.

[0028] Working principle: the staff places the material tray 17 on the loading plates 141 on the conveyor belts 14 on both sides. The loading plates 141 on both sides support the material tray 17. The start button on the control panel 1 is pressed, and the storage silo starts. The control system controls the telescopic cylinders 131 on both sides to work and the coils 144 to connect to the circuit. The coils 144 generate a magnetic field to change the magnetorheological fluid from liquid to solid. The telescopic cylinders 131 on both sides respectively drive the sliding plates 13 on both sides to move relative to each other, so that the distance between the sliding plates 13 on both sides becomes smaller. The sliding plates 13 on both sides respectively drive the conveyor belts 14 and the loading plates 141 on both sides to move relative to each other. The loading plates 141 on both sides clamp and position the material tray 17, so that the material tray 17 remains in a centered state to prevent the material tray 17 from shifting. The magnetorheological fluid is converted from a liquid state to a solid state, which prevents the conveyor belt 14 from bending and deforming during the clamping process, and can further enhance the clamping effect of the loading plate 141.

[0029] When the material tray 17 is clamped and positioned by the carrier plates 141 on both sides, the encoder in the telescopic cylinder 131 feeds back the displacement data to the control system, and the control system opens the solenoid valve in the connecting pipe between the air slip ring inlet and the carrier plate 141. The control system draws out the air in the carrier plate 141 on which the material tray 17 is placed through the negative pressure system, so that the negative pressure hole generates negative pressure to absorb the material tray 17, thereby preventing the material tray 17 from shaking during the up and down movement; When the negative pressure hole adsorbs the material tray 17, the negative pressure system feeds back the pressure signal to the control system, and the control system cuts off the power to the coil 144. After the coil 144 loses the magnetic field, the magnetorheological fluid changes from solid to liquid. After that, the control system drives the conveyor belts 14 on both sides to move downward through the rollers 142 on both sides, that is, the conveyor belt 14 on the left moves clockwise, and the conveyor belt 14 on the right moves counterclockwise, so that the conveyor belts 14 on both sides respectively drive the material tray 17 to move downward through the carrier plates 141 on both sides. During the downward movement of the tray 17, the encoder in the roller 142 feeds back the displacement data of the tray 17 to the control system in real time. The control system opens the solenoid valve in the dust removal chamber and the air slip ring inlet connecting pipe, and the negative pressure system draws the air in the dust removal chamber outward, so that the dust around the tray 17 enters the dust removal chamber through the adsorption hole 145, and is discharged to the external atmosphere through the dust removal chamber, the pipe and the air slip ring, preventing the tray 17 from being contaminated with dust during the transportation process, thereby causing problems such as slow transportation and obstruction, and avoiding the dust from having adverse effects on the parts in the tray 17.

[0030] When the material tray 17 moves close to the receiving plate 15, the encoder inside the roller 142 feeds back the displacement data on the material tray 17 to the control system, and the control system energizes the telescopic spring 151. After the telescopic spring 151 is energized, each turn generates a mutually attractive magnetic field, which compresses the telescopic spring 151, shortening the telescopic spring 151 as a whole, and the telescopic spring 151 pulls the receiving plate 15 to move upward, and the receiving plate 15 drives the transverse rod 152, the longitudinal rod 154 and the suction cup 155 to move upward, so that the suction cup 155 contacts the material tray 17, and the suction cup 155 cooperates with the negative pressure system to generate negative pressure to absorb the material tray 17; When the material tray 17 is sucked by the suction cup 155, the negative pressure system feeds back the pressure signal of the suction cup 155 to the control system, and the control system draws external air into the carrier plate 141 through the negative pressure system, so that the negative pressure hole releases the material tray 17. At this time, the material tray 17 is sucked by the suction cup 155; When the negative pressure hole releases the material tray 17, the negative pressure system feeds back the pressure signal of the negative pressure hole to the control system, and the control system cuts off the power of the telescopic spring 151. The telescopic spring 151 gradually lengthens under its own elastic force, and the telescopic spring 151 pushes the receiving plate 15 to move downward, and the receiving plate 15 drives the material tray 17 to move downward through the suction cup 155; When the receiving plate 15 drives the material tray 17 to move downward through the suction cup 155, the displacement sensor on the receiving plate 15 feeds back the displacement data of the material tray 17 to the control system, and the control system energizes the longitudinal spring 156, and the longitudinal spring 156 pulls the longitudinal rod 154 and the suction cup 155 to move downward, and the suction cup 155 drives the material tray 17 to move downward, so that the material tray 17 is located in the rectangular groove; When the longitudinal spring 156 is energized to the set time, the material tray 17 will be located in the rectangular groove. At this time, the control system cooperates with the suction cup 155 through the negative pressure system, so that the suction cup 155 does not adsorb the material tray 17, and energizes the transverse spring 153. The transverse spring 153 pulls the transverse rod 152 to move away from the material tray 17. The transverse rod 152 drives the longitudinal rod 154 and the longitudinal spring 156 to move away from the material tray 17, so that there is no obstruction directly below the rectangular groove. At this time, the material tray 17 falls downward onto the buffer plate 185 due to its own weight.

[0031] When the tray 17 falls on the buffer plate 185, the downward impact force of the tray 17 pushes the buffer plate 185 to move downward, and the buffer plate 185 compresses the shock absorbing spring 193. The shock absorbing spring 193 buffers the impact force of the tray 17, preventing the tray 17 from being damaged or the parts on the tray 17 from splashing, thereby improving the stability of the tray 17; When the material tray 17 falls on the buffer plate 185, the proximity switch on the material tray seat 16 directly below feeds back the displacement data of the material tray 17 to the control system, and the control system positions the material tray 17 by extending and retracting the positioning cylinder 161 to prevent the position of the material tray 17 from deviating; thereafter, the feeding motor 18 drives the feeding roller to rotate, the feeding roller drives the transmission belt 183 to move, the transmission belt 183 pulls the slider 182 to move on the feeding guide rail 181, the slider 182 drives the support plate 184 to move, the support plate 184 drives the buffer plate 185 to move through the guide column, and the buffer plate 185 drives the material tray 17 to move to the material tray seat 16 on the other side, thereby realizing the loading of the material tray 17.
