[0041] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present disclosure should have the common meanings understood by those skilled in the art to which the present disclosure belongs.

[0042] At present, the automotive industry is developing faster and faster, and the co-production of multiple models is becoming more and more frequent. Co-production of multiple models has become an important strategy to improve production efficiency and reduce costs. This production model allows vehicles of different models or even different brands to be assembled on the same production line. It greatly tests the supply chain management, production scheduling, logistics distribution and quality control capabilities of automobile manufacturers and their parts suppliers, especially the production, assembly and distribution of parts of the same type in different states are more complicated.

[0043] Existing parts of the same type but in different states are uniformly distributed to the assembly department through material boxes, and the assembly department selects parts of different states from the material boxes according to needs.

[0044] When workers select parts in different states, they need to identify or measure the parts in the bin, which wastes a lot of time and reduces production efficiency.

[0045] Example 1

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a material conveying device includes a longitudinal transport mechanism 1 and a transverse transport mechanism 2; the longitudinal transport mechanism 1 includes at least two oppositely arranged bearing parts 11, a plurality of supporting parts 12 arranged at intervals along the longitudinal direction, and a plurality of conveying parts 13; the supporting part 12 includes at least two supporting rods 122 and at least two telescopic members 121, the two supporting rods 122 are rotatably connected to the two bearing parts 11 respectively, the bottoms of the first ends of the two supporting rods 122 on the two bearing parts 11 that are away from each other are connected to the bearing part 11 through the telescopic member 121, and the second ends of the two supporting rods 122 that are close to each other are used to carry the objects to be conveyed; the conveying part 13 is arranged between two adjacent layers of supporting parts 12, and the conveying part 13 can reciprocate between a first position and a second position, the first position is higher than the top surface of the upper layer of supporting parts 12, and the second position is lower than the top surface of the lower layer of supporting parts 12; the transverse transport mechanism 2 is arranged between the two bearing parts 11 and on one side of the bottom layer of supporting parts 12.

[0047] The bearing part 11 is a structure for bearing the supporting part 12 and the conveying part 13; specifically, the bearing part 11 can be a column, or a bracket or any other structure that can bear the supporting part 12 and the conveying part 13. More specifically, the two bearing parts 11 can be connected together by a connecting rod to form an integrated structure, or can be separated and arranged opposite to each other. As long as the bearing part 11 can bear the supporting part 12 and the conveying part 13, the specific structure of the bearing part 11 is not limited.

[0048] The support rod 122 is a structure for carrying objects to be transported. Specifically, the support rod 122 can be a rod-shaped structure or a block-shaped structure. As long as one end of the support rod 122 can carry the objects to be transported and the other end can be connected to the telescopic member 121 to control the up and down rotation of the carrying end, the specific structure of the support rod 122 is not limited.

[0049] Specifically, any position of the support rod 122 except the two ends can be rotatably connected to the bearing portion 11. More specifically, in order to facilitate the movement of the two ends of the support rod 122, the middle position of the support rod 122 can be rotatably connected to the bearing portion 11. More specifically, as Figure 1 As shown, a through slot extending in the longitudinal direction may be provided on the side wall of the bearing portion 11, and the support rod 122 may be rotatably connected in the through slot via a rotating shaft.

[0050] The telescopic member 121 can be an active telescopic member and a passive telescopic member. When the telescopic member 121 is an active telescopic member, the telescopic member 121 can be a hydraulic cylinder, a pneumatic cylinder and an electric push rod. Specifically, when the object to be transmitted is placed on the support rod 122, the telescopic member 121 is extended, and the first end of the support rod 122 is rotated upward, so that the support rod 122 is in a horizontal position; when the object to be transmitted leaves the support rod 122 under the action of the conveying part, the telescopic member 121 is shortened, and the first end of the support rod 122 is rotated downward, so that the second end of the support rod 122 is changed from a horizontal state to an upward rotation, thereby increasing the gap between the second ends of the two relatively arranged support rods 122, so that the conveying part can transport the object to be transmitted downward from the gap; after the object to be transmitted passes through the gap, the telescopic member 121 is reset, so that the support rod 122 is still in a horizontal position to receive the items supported and transported from the upper layer.

[0051] Specifically, when the telescopic member 121 is a passive telescopic member, a follower structure can be provided on the telescopic member 121. When the conveying object leaves the support rod 122, the follower structure can move downward with the conveying part 13 to pull down the second end of the support rod 122 so as to receive the object transmitted from the upper support layer. More specifically, the follower structure can be a hook 124, a telescopic hook 124 or any other structure that can move downward with the conveying part 13.

[0052] More specifically, the telescopic member 121 may be a spring. When the object to be conveyed is placed on the second end of the support rod 122, the second end of the support rod 122 rotates downward under the action of gravity. The first end of the support rod 122 has a tendency to rotate downward under the pulling force of the first spring 127. The pressure and pulling force at both ends of the support rod 122 are balanced, so that the support rod 122 is in a horizontal position. When the object to be conveyed moves downward, under the pulling force of the spring 127, the first end of the support rod 122 rotates downward, so that the second end of the support rod 122 changes from a horizontal state to an upward rotation, thereby increasing the gap between the second ends of the two oppositely arranged support rods 122, so that the conveying unit can transport the object to be conveyed downward from the gap; when the object to be conveyed continues to move downward, the follower structure contacts the conveying unit 13, and the conveying unit 13 drives the follower structure to move downward so that the support rod 122 is still in a horizontal position to receive the objects supported and transported from the upper layer.

[0053] More specifically, multiple follow-up mechanisms may be provided, or only one follow-up mechanism may be provided. When only one follow-up mechanism is provided, the follow-up mechanism may be installed on the topmost support rod 122, and push rods 126 are provided at the bottom of all support rods 122, so that support rods 122 of other layers may also move synchronously with the support rods 122 of the topmost layer.

[0054] The conveying part 13 is a structure capable of transporting articles between two adjacent layers of supporting parts 12. Specifically, the conveying part 13 can be a manipulator, and the longitudinal transportation between the supporting layers can be completed by driving the articles to be transported up and down through the manipulator. The conveying part 13 can also be a lifting mechanism, and a load-bearing end is provided on the lifting mechanism, and the load-bearing end carries the articles to be transported up and down to complete the longitudinal inter-layer transportation of the articles. More specifically, in order to avoid the articles to be transported blocking the resetting of the lifting mechanism, the load-bearing end can be set as a retractable telescopic rod. When the lifting mechanism transports the articles to be transported to the next layer, the load-bearing end shrinks and the lifting mechanism rises and resets again, avoiding the articles to be transported blocking the lifting mechanism from rising. When the lifting mechanism is reset, the load-bearing end is also reset. More specifically, the load-bearing end of the conveying part 13 can also be a non-retractable structure, and the lifting mechanism is a mechanism that can move horizontally. When the lifting mechanism transports the articles to be transported to the next layer, the lifting mechanism can move outward to avoid the articles to be transported. More specifically, the lifting mechanism can be a hydraulic cylinder or other lifting device, and the lifting mechanism can be slidably connected to a base set at the bottom of the bearing part 11. As long as the conveying portion 13 can reciprocate between the first position and the second position to transport articles between two adjacent layers of the supporting portions 12 , the specific structure and shape of the conveying portion 13 are not limited.

[0055] The transverse transport mechanism 2 is a mechanism capable of transversely transporting the bottom support layer. Specifically, the transverse transport mechanism 2 can be a conveyor belt or a swing bed. The bottom layer of items to be transported can be transported by the friction of the conveyor belt, or a stopper 135 can be set on the conveyor belt to drive the items to move; the items can also be transported in a cycle by a swing bed. As long as the transverse transport mechanism 2 can transport the items of the bottom support layer from one side to the other side, the specific structure and shape of the transverse transport mechanism 2 are not limited.

[0056] The material conveying device provided by the present invention realizes the longitudinal layer-by-layer transportation of materials by means of the multi-layer support parts 12 arranged in the longitudinal direction and the conveying parts 13 arranged between the multi-layer support mechanisms. The support rods 122 are rotatably connected to the load-bearing part 11, and the bottoms of the first ends of the two support rods 122 on the two load-bearing parts 11 that are separated from each other are connected to the load-bearing part 11 through the telescopic parts 121, so that when the objects to be conveyed are placed on the support rods 122, the second ends of the support rods 122 can be horizontal under the action of the gravity of the objects to be conveyed, and when the objects to be conveyed leave the support rods 122 under the action of the conveying part and are in the first position, the second ends of the support rods 122 can be tilted, thereby increasing the distance between the second ends of the two support rods 122. The distance between them is such that the articles to be conveyed can be driven by the conveying part to move down from the gap between the second ends of the two support rods 122 to the second position, and then fall onto the next layer of support rods 122 that have been reset, so that the parts can be transported step by step between the multiple layers of support mechanisms and the articles to be conveyed on the bottom layer of support parts 12 can be transported away by the horizontal transport mechanism 2, so that the parts can be continuously delivered to the assemblers layer by layer according to the arrangement order in the longitudinal transport mechanism 1. When the assemblers select the parts in different states, they no longer need to identify or measure the parts in the material box, so that the on-site or logistics personnel can reduce the assembly, distribution and waiting time, improve efficiency and reduce the labor intensity of the staff.

[0057] In another embodiment of the present disclosure, the transverse transport mechanism 2 includes two relatively arranged support frames 23, a conveying part 21, at least two first connecting rods 22 and a driving motor 25; the conveying part 21 is arranged between the two support frames 23, the conveying part 21 is rotatably connected to one end of the first connecting rod 22, and the other end of the first connecting rod 22 is rotatably connected to the support frame 23, the two first connecting rods 22 are parallel to each other and rotatably connected on the same side of the support frame 23, the two first connecting rods 22 are driven by the driving motor 25, the highest point of the travel of the conveying part 21 is between the last layer of support portion 12 and the upper layer of support portion 12, and the lowest point of the travel of the conveying part 21 is lower than the last layer of support portion 12.

[0058] The support frame 23 is a structure that can provide accommodation space and rotation connection points for the conveying part 21. Specifically, the two support frames 23 can be two independently arranged structures, or they can be connected together to form a conveying platform to improve the stability of the overall structure, and the specific structure and shape of the support frame 23 are not limited.

[0059] The conveying part 21 is a structure for carrying the objects to be conveyed. Specifically, the conveying part 21 can be a plate-shaped structure or a frame structure. As long as the conveying part 21 can carry the objects to be conveyed and move laterally, the specific structure of the conveying part 21 is not limited.

[0060] Specifically, two first connecting rods 22 can be provided. In order to make the transmission process of the first connecting rod 22 more stable, four first connecting rods 22 can also be provided. The four transmission rods 3 can be symmetrically provided on both sides of the transmission part 21, and all are rotatably connected to the inner wall of the support frame 23. The provision of four transmission rods 3 can make the transmission process of the first connecting rod 22 more stable. More specifically, the multiple transmission rods 3 can be connected by multiple motors, or driven by a driving motor 25. More specifically, the two first connecting rods 22 on the same side can be connected to the sleeve, the sleeve is rotatably connected to the rotating shaft, the rotating shaft is fixedly connected to the inner wall of the support frame 23, the outer side of the sleeve is provided with gear teeth, the two gear teeth on the same side are connected to one end of the driving shaft through an annular rack, and the driving shaft is connected to the driving motor 25. That is, the motor drives the driving shaft to rotate, and the two ends of the driving shaft respectively drive the two annular racks to rotate, the rotation of the annular rack drives the sleeve 1241 provided with gear teeth to rotate, and the rotation of the sleeve 1241 drives the first connecting rod 22 to rotate, thereby driving the transmission part 21 to swing up and down and left and right. More specifically, the gear teeth may be directly arranged on the rotating shaft, and the rotating shaft is connected to the inner wall of the support frame 23 via a bearing.

[0061] By making the conveying part 21 rotatably connected to one end of the first connecting rod 22, and the other end of the first connecting rod 22 rotatably connected to the support frame 23, the two first connecting rods 22 are parallel to each other and rotatably connected to the same side of the support frame 23, so that the conveying part 21 can swing up and down, left and right, and move in an approximately elliptical trajectory. It is also made that the highest point of the travel of the conveying part 21 is between the last layer of support part 12 and the upper layer of support part 12, and the lowest point of the travel of the conveying part 21 is lower than the last layer of support part 12. In this way, the conveying part 21 can swing to the position of the last layer of support part 12 and take out the items to be conveyed from bottom to top, and move from the position of the longitudinal transport mechanism 1 to a position away from it, so as to transport the items to be conveyed horizontally. Through this bottom-to-top transportation method, the obstruction of the support part 12 can be bypassed, and it is more convenient to take out the items to be conveyed on the support part 12.

[0062] In another embodiment of the present disclosure, a plurality of limit blocks 24 are arranged at the top of the conveying part 21, and the plurality of limit blocks 24 are arranged at intervals along the extension direction of the conveying part 21; wherein, the highest point of the travel of the conveying part 21 is higher than the top surface of the support frame 23. By arranging a plurality of limit blocks 24 at the top of the conveying part 21, on the one hand, the objects to be conveyed can be clamped between two adjacent limit blocks 24, thereby improving the stability of the transported objects; on the other hand, by making the highest point of the travel of the conveying part 21 higher than the top surface of the support frame 23, the objects conveyed by the conveying part 21 can fall on the top surface of the support frame 23. When the conveying part 21 circulates to the highest point, the limit blocks 24 or the front end of the conveying part 21 can push the objects on the top surface of the support frame 23 to move to the side away from the longitudinal transmission mechanism, and place the next object on the top surface of the support frame 23. By analogy, the objects on the longitudinal transmission mechanism can be arranged in order on the top surface of the support frame 23, which is more convenient for the staff to take.

[0063] In another embodiment of the present disclosure, an infrared transmitter 26 and an infrared receiver are provided at one end of the support frame 23 away from the support portion 12. The infrared transmitter 26 and the infrared receiver are provided on opposite sides of the inner wall of the support frame 23. The drive motor 25 and the infrared receiver are both connected to the controller; a baffle 27 is provided on the side of the infrared transmitter 26 close to the infrared receiver. The baffle 27 is higher than the top surface of the support frame 23, and the baffle 27 is slidably connected to the inner wall of the support frame 23. Specifically, the baffle 27 can be slidably connected to the inner wall of the support frame 23 along the extension direction of the support frame 23. When the items are transferred to the end of the support frame 23 away from the support portion 12, it means that the support frame 23 is full of items, and the items push the baffle 27 to move to the side away from the support portion 12, thereby blocking the infrared transmitter 26, so that the infrared receiver cannot receive the signal of the infrared transmitter 26, and the controller controls the drive motor 25 to stop rotating, completing the transportation process. By providing the infrared transmitter 26, the infrared receiver and the baffle 27, the work can be automatically stopped after the transportation is completed, which is more convenient to use.

[0064] In another embodiment of the present disclosure, Figure 5As shown, a slot 112 is provided on one side of the bearing portion 11 close to the second end of the support rod 122; the support portion 12 also includes a movable boss 123, a first spring 127, a second connecting rod 128 and a block 129, and the bottom of the movable boss 123 is connected to the second end of the support rod 122 through the first spring 127; the movable boss 123 is rotatably connected to one end of the second connecting rod 128 on one side close to the bearing portion 11, and the other end of the second connecting rod is rotatably connected to the block 129, and the block 129 is slidably connected in the first sliding groove 1210 of the side wall of the support rod 122, the first sliding groove 1210 is connected to the slot 112, and the block 129 cooperates with the slot 112. When the object to be transported is on the second end of the support rod 122, the movable boss 123 will overcome the elastic force of the first spring 127 and move downward under the action of gravity, thereby driving one end of the second connecting rod 128 to move downward and rotate, thereby pushing the other end of the second connecting rod 128 to rotate and move toward the side close to the bearing part 11, so that the block 129 enters the slot 112 of the bearing part, thereby limiting the rotation of the support rod 122, so that the support rod 122 is maintained in a horizontal position, and the stability of the support is improved. Conversely, when the object to be transported leaves the movable boss, the block is driven by the spring and the second connecting rod to disengage from the slot, so that the support rod can rotate and reset.

[0065] In another embodiment of the present disclosure, Figure 4 As shown, the conveying portion 13 includes a slider 131, a plug-in slot 132, a fourth connecting rod 133, a limiting rod 136 and a fifth connecting rod 134. A stopper 135 is provided at the bottom of the plug-in slot 132. The slider 131 is plugged into the plug-in slot 132. The slider 131 and the fourth connecting rod 133 are coaxially connected to the bearing portion 11. The fourth connecting rod 133 is fixedly connected to the limiting rod 136 on one side close to the bearing portion 11. The limiting rod 136 is slidably connected in the limiting slot 111 of the side wall of the bearing portion 11. One end of the fourth connecting rod 133 is rotatably connected to one end of the fifth connecting rod 134, and the other end of the fifth connecting rod 134 is rotatably connected to the plug-in slot 132.

[0066] The upper support rods 122 of the bottom support rods 122 are all provided with hooks 124, the hooks 124 are fixedly connected to the side walls of the support rods 122, and the hooks 124 are arranged within the travel range of the plug-in slots 132; the upper support rods 122 of the bottom support rods 122 are provided with push rods 126 at the bottom, and the push rods 126 can contact the bottom support rods 122;

[0067] Alternatively, the topmost support portion 12 is provided with a hook 124, which is fixedly connected to the side wall of the support rod 122, and the hook 124 is arranged within the travel range of the plug-in slot 132. The bottom of the upper support rod 122 of the bottommost support rod 122 is provided with a push rod 126, which can contact the support rod 122 of the adjacent layer.

[0068] Specifically, the slider 131 may be a long strip block structure or other structure that can cooperate with the insertion slot 132. More specifically, a through slot may be provided on the side wall of the slider 131, and the fourth connecting rod 133 passes through the through slot, and a pin passes through the slider 131, the fourth connecting rod 133 and the receiving portion, so that the fourth connecting rod 133 and the slider 131 are coaxially connected to the receiving portion.

[0069] More specifically, one or more limiting grooves 111 may be provided, and a closed limiting groove 111 may be provided to limit the rotation of one end of the fourth connecting rod 133, thereby limiting the rotation of the fourth connecting rod 133. Two limiting grooves 111 open on the same side may also be provided, and the two ends of the fourth connecting rod 133 are respectively slidably connected in the two limiting grooves 111 through connecting members, thereby limiting the rotation of the fourth connecting rod 133. As long as the limiting rod 136 can be stuck on the edge of the limiting groove 111 when the object is moved to the position where the next supporting layer is located, thereby limiting the rotation of the fourth connecting rod 133, the specific structure and shape of the limiting groove 111 are not limited.

[0070] More specifically, the plug-in slot 132 may be a hollow structure with a long strip groove or other structure that can slide with the slider 131. A receiving plate may be provided on the side of the plug-in slot 132 away from the slider 131, and the receiving plate may be at a set angle with the sliding direction of the slider 131, so that the receiving plate is arranged horizontally, thereby supporting the items more stably. More specifically, the side panels of the plug-in slot 132 may be arranged as bent plates, the side panels close to the slider 131 extend along the sliding direction of the slider 131, the other side panel and this side panel form an obtuse angle, and the horizontal receiving plate is perpendicular to the other side panel; the side wall of the plug-in slot 132 may also be provided with a bent plate to complete the connection between the sliding section of the plug-in slot 132 and the horizontally arranged receiving plate.

[0071] More specifically, the end of the slider 131 away from the insertion slot 132 can be connected to a driving device so that the slider 131 can move up and down. For example, the driving device can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod. The end of the slider 131 away from the insertion slot 132 can also be connected to a linkage device so that it can move up and down with the movement of the horizontal transport mechanism 2, as long as the slider 131 can move up and down. When the slider 131 moves downward, the insertion slot 132 moves upward to take away the items; when the insertion slot 132 moves downward, it shrinks and stretches, so as to move the items to the position of the next support layer. At this time, the limit rod 136 is just stuck on the edge of the limit slot 111, limiting the rotation of the fourth connecting rod 133. At this time, the fourth connecting rod 133 rotates around its hinge point with the fifth connecting rod 134, thereby driving the insertion slot 132 to further shrink, and then separating the conveying part from the items to be transported.

[0072] In order to allow the articles transported from the upper supporting layer to fall on the lower supporting layer, a hook 124 is provided. The hook 124 can move downward along with the downward movement of the insertion slot 132 of the lower conveying part, so that the supporting layer can be reset when the articles transported from the upper conveying part arrive at the supporting layer.

[0073] More specifically, the upper support rods 122 of the lowest support rods 122 can be provided with hooks 124, the hooks 124 are fixedly connected to the side walls of the support rods 122, and the hooks 124 are arranged within the travel range of the plug-in slots 132; the upper support rods 122 of the lowest support rods 122 are provided with push rods 126 at the bottom, and the push rods 126 can contact the lowest support rods 122. That is, all support rods 122 except the lowest support rods 122 are provided with hooks 124, and the support rods 122 provided with hooks 124 are reset under the drive of the conveying part plug-in slots 132. Since there is no conveying part at the bottom of the support rods 122 of the lowest layer, push rods 126 are provided at the bottom of the upper support rods 122 of the lowest support rods 122, and the push rods 126 drive the lowest support rods 122 to reset synchronously.

[0074] More specifically, a hook 124 may be provided on the support portion 12 of the top layer, the hook 124 is fixedly connected to the side wall of the support rod 122, the hook 124 is provided within the travel range of the insertion slot 132, and a push rod 126 is provided at the bottom of the upper support rod 122 of the bottom layer support rod 122, and the push rod 126 can contact the support rod 122 of the adjacent layer. The support rod 122 of the top layer is driven to reset by the hook 124, and the support rod 122 of the top layer drives the support rods 122 of other layers to reset.

[0075] More specifically, a ball bearing may be provided at the bottom of the push rod 126 to reduce the friction force when the push rod 126 pushes the support rod 122. The hook 124 may be provided as a fixed hook 124 or a sliding hook 124. The hook 124 may be provided as an elastic hook 124 to prevent the movement of the plug-in slot 132 from being affected when the plug-in slot 132 and the hook 124 are in contact. More specifically, in order to ensure that the plug-in slot 132 can drive the hook 124 to move and prevent the plug-in slot 132 from being separated from the hook 124 during movement, a stopper 135 may be provided at the bottom of the plug-in slot 132. During movement, the stopper 135 contacts the hook 124, thereby preventing the hook 124 from falling off during movement.

[0076] In another embodiment of the present disclosure, Figure 6As shown, the hook 124 includes a sleeve 1241, a sleeve rod 1242, a second spring 1244, a pressure plate 1245 and a connecting hook 1243. The sleeve 1241 is fixedly connected to the side wall of the support rod 122, the pressure plate 1245 is slidably connected in the sleeve 1241, the pressure plate 1245 and the sleeve 1241 are connected by the second spring 1244, the pressure plate 1245 is fixedly connected to the first end of the sleeve rod 1242, and the second end of the sleeve rod 1242 is fixedly connected to the connecting hook 1243.

[0077] Specifically, the second spring 1244 can be sleeved on the outside of the sleeve rod 1242, one end of the second spring 1244 is connected to the pressure plate 1245, and the other end is connected to the side of the sleeve 1241 close to the connecting hook 1243. When the sleeve rod 1242 moves downward, the second spring 1244 is compressed and the hook 124 is extended; when the hook 124 is separated from the plug slot 132, the second spring 1244 is extended and the hook 124 is reset. The second spring 1244 can also be connected to the pressure plate 1245 at one end and connected to the side of the sleeve 1241 away from the connecting hook 1243 at the other end. When the sleeve rod 1242 moves downward, the second spring 1244 is extended and the hook 124 is extended; when the hook 124 is separated from the plug slot 132, the second spring 1244 is retracted and the hook 124 is reset. As long as the hook 124 can be extended and reset, the specific structure of the hook 124 is not limited.

[0078] In another embodiment of the first aspect of the present disclosure, the longitudinal transport mechanism 1 further includes a third connecting rod 125, four bearing parts 11 are provided, and the four bearing parts 11 are symmetrically arranged on both sides of the transverse transport mechanism 2, and two support rods 122 arranged at the same height on two bearing parts 11 on the same side are connected by the third connecting rod 125;

[0079] A receiving groove 137 is provided at one end of the insertion groove 132 away from the slider 131, and the receiving groove 137 is used to receive the object to be conveyed;

[0080] The two sliding blocks 131 at the same height on the two bearing parts 11 on the same side are connected by the sixth connecting rod 14, and the multiple sixth connecting rods 14 on the same side are connected to the seventh connecting rod 37. The seventh connecting rod 37 can move up and down, thereby driving the receiving groove 137 to move between the first position and the second position. The first position of the receiving groove 137 is higher than the top of the movable boss 123 of the upper-level support rod 122, and the second position of the receiving groove 137 is lower than the top of the movable boss 123 of the lower-level support rod 122.

[0081] Specifically, the receiving groove 137 is a groove-shaped structure for receiving the items to be transported. More specifically, the receiving groove 137 can be composed of the above-mentioned receiving plate and a protrusion, and the protrusion is arranged on a side away from the center of the longitudinal transmission mechanism, so that the four protrusions can clamp the items in the center of the longitudinal transmission mechanism, further improving the stability of the transported items by the transmission part. More specifically, the protrusion can be a square protrusion, a round protrusion or a triangular protrusion, as long as the protrusion can clamp the items, and the specific structure and shape of the protrusion and the receiving groove 137 are not limited.

[0082] The seventh connecting rod 37 can be connected by a driving device to achieve up and down movement, or can be connected by a follower structure and the transverse transport mechanism 2 to achieve up and down movement under the drive of the transverse transport mechanism 2. Specifically, the driving device can be any structure that can drive the seventh connecting rod to move up and down, such as a hydraulic cylinder, a pneumatic cylinder or an electric push rod. By setting the seventh connecting rod and multiple sixth connecting rods, the multi-layer conveying parts can all move synchronously, thereby enhancing the integrity and coordination of the movement.

[0083] By providing four load-bearing parts 11 and symmetrically arranging the four load-bearing parts 11 on both sides of the transverse transport mechanism 2, each layer has four support rods 122 to support the articles, thereby improving the stability of the articles on the support layer. By connecting two support rods 122 at the same height on two load-bearing parts 11 on the same side through a third connecting rod 125, it is possible to ensure that the support rods 122 on the same side can move synchronously, thereby avoiding the situation where the objects are skewed due to the second ends of the support rods 122 being in different positions.

[0084] When the receiving groove 137 is in the first position, the second end of the support rod 122 is lifted, and the object to be conveyed is in the gap between the two relatively arranged support rods 122; when the receiving groove 137 moves to the second position, the hook 124 contacts the stopper 135, and the hook 124 drives the second end of the support rod 122 to move downward, so that the upper-level support rod 122 is reset, and the lower-level support rod 122 is also reset under the drive of the lower-level conveying part 13; when the object to be conveyed falls into the lower-level support rod 122, the limiting rod 136 rotates to the edge of the limiting groove 111, the fourth connecting rod 133 no longer rotates, and the fifth connecting rod 134 starts to rotate, thereby driving the insertion groove 132 to shrink and then disengage from the object to be conveyed; after the upper-layer support rod 122 of the lowest support rod 122 is reset, the push rod 126 pushes the lowest support part 12 to reset, and the object to be conveyed on the upper-layer support rod 122 of the lowest support rod 122 falls onto the lowest support rod 122.

[0085] In another embodiment of the first aspect of the present disclosure, the transmission portion 21 and the two seventh connecting rods 37 are connected via two transmission rods 3 respectively;

[0086] The transmission rod 3 includes a first linkage rod 34, a linkage shaft 35, and a second linkage rod 36. A roller 33 is provided at one end of the first linkage rod 34. The outer side of the roller 33 contacts the transmission part 21. An annular slide groove is provided inside the roller 33. The annular slide groove is rotatably connected to one end of the connecting hook 31. The other end of the connecting hook 31 is slidably connected in the second slide groove 39. The second slide groove 39 is provided on the side of the transmission part 21 close to the longitudinal transport mechanism 1. The first linkage rod 34 can swing between the third position and the fourth position; the other end of the first linkage rod 34 is connected to the linkage shaft 35, the linkage shaft 35 is connected to one end of the second linkage rod 36, and the other end of the second linkage rod 36 is rotatably connected to one end of the seventh connection rod 37; a plurality of connection blocks 38 are provided on the side wall of the seventh connection rod 37, and a second slide groove 39 is provided in the connection block 38. The sixth connection rod 14 is connected in the second slide groove 39;

[0087] Among them, the second linkage rod 36 is arranged on a side away from the conveying part 21, and the extension directions of the first linkage rod 34 and the second linkage rod 36 are opposite; when the conveying part 21 is at the highest point, the first linkage rod 34 is in the third position, and the receiving groove 137 is in the first position; when the conveying part 21 is at the lowest point, the first linkage rod 34 is in the fourth position, and the receiving groove 137 is in the second position.

[0088] Specifically, when the transverse transport mechanism 2 swings up and down, left and right, its transverse movement is converted into the transverse sliding of the connecting hook 31 in the second slide groove 39, and its longitudinal movement is converted into its movement between the third position and the fourth position. More specifically, when the transverse transport mechanism 2 moves downward, the transverse movement mechanism presses down the roller 33, and the connecting hook 31 slides in the second slide groove 39, so that the roller 33 moves downward, and the first linkage rod 34 rotates around the linkage shaft 35 to the lowest point, that is, the fourth position; when the transverse transport mechanism 2 moves upward, the connecting hook 31 drives the roller 33 to move upward, and the first linkage rod 34 rotates around the linkage shaft 35 to the highest point, that is, the fourth position. That is, the swinging of the transverse transport mechanism 2 up and down, left and right is converted into the swinging of the first linkage rod 34 between the third position and the fourth position through the connecting hook 31 and the roller 33.

[0089] More specifically, since the first linkage rod 34 and the second linkage rod 36 are coaxially connected, and the first linkage rod 34 and the second linkage rod 36 extend in opposite directions, when the first linkage rod 34 swings between the highest point and the lowest point, the second linkage rod 36 swings between the opposite lowest point and the highest point, thereby driving the seventh connection rod 37 to swing. In addition, since a plurality of connection blocks 38 are provided on the side wall of the seventh connection rod, and a third slide groove is provided in the connection block 38, and the sixth connection rod 14 is connected in the third slide groove, when the seventh connection rod 37 swings, the seventh connection rod 37 drives the sixth connection rod 14 to move up and down, and the sixth connection rod 14 slides in the third slide groove, thereby driving the sixth connection rod 14 to move between its lowest point and highest point, that is, driving the slider 131 to move between its lowest point and highest point, and the plug slot 132 at the other end of the transmission rod to move between its highest point and lowest point.

[0090] More specifically, when the transverse transport mechanism 2 is at the highest point, the first linkage rod 34 is at the highest point, the second linkage rod 36 is at the lowest point, the seventh connecting rod 37 is at the lowest point, the sixth connecting rod 14 and the slider 131 are at the lowest point, and the receiving groove 137 in the plug-in groove 132 is at the highest point. That is, the transverse transport mechanism 2 and the receiving groove 137 are synchronously moved in the vertical direction through the transmission rod 3, so that when the transverse transport mechanism 2 swings up and down and left and right for one cycle, the receiving groove 137 swings from the highest point to the lowest point, and then swings from the lowest point to the highest point.

[0091] The transfer rod 3 enables the lateral transport mechanism 2 and the receiving groove 137 to move synchronously in the vertical direction, thereby increasing the integrity and coordination of the entire device, so that the process of the lateral transport mechanism 2 taking away items on the bottom support layer is synchronized with the process of other transfer rods 3 transporting items between support layers, thus avoiding conflicts between the lateral transport mechanism 2 and the transfer rod 3.

[0092] Embodiment 2

[0093] A multi-vehicle co-line manufacturing system comprises the above-mentioned material conveying device.

[0094] The multi-vehicle co-line manufacturing system provided by the present invention realizes the longitudinal layer-by-layer transportation of materials by means of the multi-layer support parts 12 arranged in the longitudinal direction and the conveying parts 13 arranged between the multi-layer support mechanisms. The support rods 122 are rotatably connected to the load-bearing part 11, and the bottoms of the first ends of the two support rods 122 on the two load-bearing parts 11 that are separated from each other are connected to the load-bearing part 11 through the telescopic parts 121, so that when the objects to be transported are placed on the support rods 122, the second ends of the support rods 122 can be horizontal under the gravity of the objects to be transported, and when the objects to be transported leave the support rods 122 under the action of the conveying part and are in the first position, the second ends of the support rods 122 can be tilted, thereby increasing the second ends of the two support rods 122. The distance between them is large, so that the items to be transported can be moved down from the gap between the second ends of the two support rods 122 to the second position under the drive of the conveying part, and then fall onto the next layer of support rods 122 that have been reset, so that the parts can be transported step by step between the multiple layers of support mechanisms and the items to be transported on the bottom layer of support parts 12 can be transported away through the horizontal transport mechanism 2, so that the parts can be continuously delivered to the assemblers layer by layer according to the arrangement order of the longitudinal transport mechanism 1. When the assemblers select parts in different states, they no longer need to identify or measure the parts in the material box, so that the on-site or logistics personnel can reduce the assembly, distribution and waiting time, improve efficiency and reduce the labor intensity of the staff.

[0095] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
