[0124] An operation table 404 is fixedly arranged on the upper side of the horizontal conveying belt 4012, and the push plate assembly 402 and the clamping jaw assembly 403 are arranged at the two sides of the operation table 404, respectively. The operation table 404 comprises a horizontal fixed plate 4041 and a fixed table 4042 arranged on the horizontal fixed plate 4041, and the fixed table 4042 is internally provided with corresponding circuit control components.

[0125] The fixed table 4042 is fixedly arranged on the horizontal fixed plate 4041, and the push plate assembly 402 is arranged at one side of the fixed table 4042, and the clamping jaw assembly 403 is arranged at the other side of the fixed table. The specific structure is as follows:

[0126] The push plate assembly 402 comprises a push plate lifting oil cylinder 4021 and a push plate 4022, wherein the side wall of the push plate lifting oil cylinder 4021 is fixedly connected with the side walls of the horizontal fixed plate 4041 and the fixed table 4042, the movable end of the push plate lifting oil cylinder 4021 is two synchronous push plate piston rods 4023, the bottom end of a push plate fixed table 4024 is fixedly connected with the top of the push plate piston rod 4023, and the top end of the push plate fixed table 4024 is provided with a vertical plate surface of the push plate 4022 facing the moving direction of the graphite box. When the push plate piston rod 4023 is at the low position, the top end of the push plate 4022 is lower than the position of the longitudinal support rod 301, so that the graphite box can be pushed to the longitudinal support rod 301 when stored. When the push plate piston rod 4023 is at the high position, the push plate 4022 is higher than the position of the longitudinal support rod 301, and the plate surface of the push plate 4022 can contact the graphite box placed on the longitudinal support rod 301, so as to realize the pushing of the graphite box by the push plate 4022.

[0127] The clamping jaw assembly 403 comprises a clamping jaw lifting oil cylinder 4031, a clamping jaw adjusting air cylinder 4032, a clamping jaw connecting component 4033 and a gas jaw 4034. The clamping jaw connecting component 4033 comprises an upper horizontal plate 40331, a side plate 40332 and a lower horizontal plate 40333.

The gas jaw 4034 is a purchased component, and the beginning thereof is provided with movable upper and lower clamping jaws. The upper clamping head 40341 of the upper clamping jaw and the lower clamping head 40342 of the lower clamping jaw are horizontally arranged and opposite to each other, so as to realize the clamping and retracting actions of the graphite box. The lower surface of the upper clamping head 40341 and the upper surface of the lower clamping head 40342 are both provided with a polyurethane layer, which can effectively protect the graphite box.

[0128] The inner side of the two longitudinal supporting rods 301 is provided with an axially horizontally arranged bearing wheel 3011, and the distance between the two rows of bearing wheels is equal to the distance between the two rows of guide wheels 1021 in the storage position. The rolling direction of the bearing wheel 3011 is consistent with the conveying direction of the graphite box, and the bearing wheel is composed of a polyurethane rubber wheel with a bearing skeleton, so as to cooperate with the conveying component to convey the graphite box assembly and avoid vibration during the conveying process.

[0129] The top of the longitudinal supporting rod is provided with an axially vertically arranged lateral guide wheel 3012, and the rolling direction of the lateral guide wheel 3012 is consistent with the conveying direction of the graphite box. The lateral guide wheel 3012 is composed of a polyurethane rubber wheel with a bearing skeleton, so as to cooperate with the conveying component to convey the graphite box assembly and play a guiding role on the graphite box. The lateral vibration of the graphite box assembly during the conveying process is absorbed by the polyurethane.

[0130] When the clamping jaw piston rod 40311 is in the low position, the height of the upper horizontal plate 40331 is lower than the height of the longitudinal supporting rod 301, so as to ensure that the whole clamping jaw assembly 403 is lower than the longitudinal supporting rod 301, so that the graphite box can be pushed onto the longitudinal supporting rod 301 during storage. When the clamping jaw piston rod 40311 is in the high position, the height of the gas jaw 4034 can be aligned with the graphite box, so as to realize the taking out of the graphite box.

[0131] The conveying method of the horizontal conveying device is as follows:

[0132] For the case of pushing the graphite box to the storage position, the steps are as follows:

[0133] The height of the push plate piston rod is adjusted by the push plate lifting oil cylinder to match the height of the graphite box;

[0134] The upper side of the horizontal transmission belt is driven by the horizontal drive motor to move inward, and the operating table and the push plate are driven by the horizontal transmission belt to move inward, and the push plate pushes the graphite box to move towards the storage position. When the graphite box is pushed by the push plate to the storage position, the upper side of the horizontal transmission belt is driven by the horizontal drive motor to move outward, and the operating table and the push plate are driven to return to the initial position on the outside;

[0135] The height of the push plate piston rod is adjusted to the initial position, so that the height of the push plate is lower than the height of the longitudinal supporting rod;

[0136] For the case of clamping the graphite box from the storage position to the longitudinal supporting rod, the steps are as follows:

[0137] The height of the push plate piston rod is adjusted by the push plate lifting oil cylinder to match the height of the graphite box;

[0138] Before clamping the graphite box, the distance between the upper and lower grab heads is slightly larger than the thickness of the graphite box, and the horizontal drive motor drives the horizontal transmission belt to drive the operating table and the push plate to move towards the graphite box;

[0139] When the grabber moves to a position where it can clamp the graphite box, that is, the lower surface of the upper grab head and the upper surface of the lower grab head are opposite the edge of the graphite box to be clamped, the cylinder piston rod of the adjusting cylinder is retracted, the upper grab head naturally falls on the upper surface of the graphite box under the action of gravity, and the gas claw 4034 is actuated, the upper and lower grab heads are tightened, thereby clamping the graphite box. At this time, the horizontal drive motor drives the horizontal transmission belt to drive the operating table and the push plate to move outward, and the graphite box is clamped by the grabber under the guidance of the lateral guide wheel and slides along the bearing wheel to the longitudinal supporting rod. When the graphite box is completely moved to the longitudinal supporting rod, the distance between the upper and lower grab heads is slightly larger than the thickness of the graphite box again, so as to loosen the grabber, and the grabber is continuously withdrawn to the outside of the graphite box;

[0140] The height of the push plate piston rod is adjusted by the push plate lifting oil cylinder to match the height of the graphite box;

[0141] The box is a sealed box, and the box is a taking and placing side wall 101 on the side away from the storage area, such as Figure 11 、 Figure 12As shown, the taking and placing side wall 101 is provided with a taking and placing opening 1011 matching the size of the graphite box, and a gate 1012 is arranged at the taking and placing opening 1011.
