[0027] The purpose, advantages and characteristics of the utility model will be illustrated and explained by the following non-restrictive description of the preferred embodiment. These embodiments are only typical examples of the application of the technical scheme of the utility model, and any technical scheme formed by equivalent replacement or equivalent transformation falls within the scope of the utility model.

[0028] In the description of the scheme, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of description and simplification of description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, the operator is taken as the reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0029] The utility model discloses a kind of three-dimensional transfer modules, including as Figures 1 to 3 The outer side of the conveying line 1 is provided with a temporary storage assembly 2 moving along the Z-axis direction and a carrying assembly 3 moving along the Y-axis direction. The product placed on the conveying line 1 is placed in the temporary storage assembly 2 after being grabbed by the carrying assembly 3 after reaching the designated position, and then moved to the processing position at the output end of the conveying line 1 by the carrying assembly 3 or a known structure such as a mechanical hand. The product to be processed is moved from the conveying line to the buffer layer of the temporary storage assembly by the carrying assembly, or the product in the buffer layer of the temporary storage assembly is moved to the processing position, effectively avoiding the product to be processed from being stranded or accumulated on the conveying line, ensuring the processing efficiency and the processing yield rate; And the overall structure is simple and compact, with small floor area and universality.

[0030] Further, as Figure 4The conveyor line 1 shown is composed of a first conveyor section 11 and a second conveyor section 12 coaxially arranged; both are controlled by a first conveyor motor 111 and a second conveyor motor 121, respectively. Both the first conveyor end 11 and the second conveyor end 12 consist of a set of parallel conveyor rollers, all of which are located on the same plane. Preferably, the conveyor line is designed as a two-section structure, each driven by a separate conveyor motor. In practical application, the rotational speeds of the first and second conveyor motors can be adjusted according to processing requirements. Preferably, the rotational speed of the second conveyor motor is less than that of the second conveyor end, so that the handling components can quickly grab products from the second conveyor end, ensuring processing efficiency while preventing product accumulation and retention.

[0031] Furthermore, damping elements 10 are symmetrically arranged on the conveying rollers of both the first conveying section 11 and the second conveying section 12. Each damping element 10 is movable along the direction of the conveying roller, and its end has a limiting protrusion protruding from its main body. By adjusting the distance between two damping elements 10 on the same conveying roller, products of different widths can be accommodated. Simultaneously, the limiting protrusions on the damping elements can guide and limit the movement of the product on both sides, ensuring that the product travels in a straight line during conveying. All damping elements 10 arranged along the conveying direction of the conveying line 1 can be controlled by the same controller to move along the direction of the conveying roller. This controller can be a component with linear movement function disclosed in the prior art, including cylinders, linear motors, etc., which will not be elaborated here.

[0032] like Figure 1 As shown, the second conveying section 12 is also provided with a blocking member 13, and the blocking member 13 is located between two adjacent conveying rollers; it includes a blocking cylinder 131 and a stop bar 132.

[0033] Combination Figure 1 and Figure 4 As shown, at least the second conveying section 12 is equipped with a material sensor 122. Specifically, as shown... Figure 4 As shown, the material sensor 122 is located at the input end of the second conveying section 12 to detect whether there is a product on the second conveying section 12. When the product to be processed moves to the material sensor 122, the material sensor 122 triggers a material signal and sends the signal to the blocking member 13. After receiving the signal from the material sensor 122, the blocking member 13 activates the blocking cylinder 131 to drive the stop rod 132 upward to block the product from continuing to move towards the conveying end. By setting the material sensor and the blocking member on the second conveying section, when there is a product being processed at the processing position, the product on the second conveying section is limited by the blocking member, effectively preventing the product to be processed from flowing out and accumulating.

[0034] As Figure 3 and Figure 4 shown, the second conveying end 12 is also provided with a to-position sensor 123 and an alarm sensor 124. Among them, the blocking piece 13 is arranged beside the to-position sensor 123; and the to-position sensor 123 is arranged at the distal end of the material sensor 122, closer to the output end of the second conveying section 12; further, the to-position sensor 123 is arranged between the material sensor 122 and the output end of the second conveying section 12. When the product to be processed moves to the to-position sensor 123, the to-position sensor 123 obtains a material signal and sends a start signal to the carrying assembly 3 to trigger the carrying assembly 3 to move the product from the second conveying section 12 to the temporary storage assembly 2.

[0035] As Figure 4 shown, the alarm sensor 124 is arranged at the output end of the second conveying section 12 and triggers an alarm signal after detecting the product. When the processing position at the conveying end of the conveying line 1 is in an empty processing state, i.e. there is no product on the processing position, the alarm sensor 124 is started, and the material sensor 122 and the to-position sensor 123 are turned off, so that the product can be smoothly output from the second conveying section 12 and trigger a prompt material taking signal when reaching the alarm sensor 124.

[0036] In addition, after the alarm sensor 124 is started, the alarm sensor 124 can also send a material putting signal to the carrying assembly 3 to trigger the carrying assembly 3 to move the product from the temporary storage assembly 2 to the second conveying section 12 and output. The carrying assembly 3 is driven by the to-position sensor or the alarm sensor to work, without manual intervention throughout, improving the automatic operation performance, saving labor cost and improving and ensuring the work efficiency. Of course, the first conveying end 11 can also be provided with the above three kinds of sensors, and the setting positions of the three kinds of sensors are equivalent to those of the three kinds of sensors on the second conveying end 12, which will not be repeated here.

[0037] In combination with Figure 3 and Figure 5As shown, the temporary storage assembly 2 comprises a Z-axis driving mechanism 21 and a temporary storage rack 22. The Z-axis driving mechanism 21 is a component with linear movement function arranged along the Z-axis direction, such as a cylinder, a linear module, a lead screw, etc. The opening of the temporary storage rack 22 faces the conveying line 1 and comprises a set of buffer layers 221 arranged along the Z-axis direction at intervals, and the distance between two adjacent buffer layers 221 is greater than the height of the gripper 32 in the carrying assembly 3. The Z-axis driving mechanism 21 is provided with an infrared sensor 23, which can also be replaced by a fiber sensor or a proximity sensor in other embodiments. The infrared sensor 23 is arranged towards the temporary storage rack 22 to detect whether there is a product on the corresponding buffer layer 221.

[0038] Further, as shown in Figure 5 Each buffer layer 221 is composed of two support rods arranged along the X-axis direction, and the end of each support rod is provided with a limiting block 222. Each limiting block 222 is formed with a notch for placing a product. The Z-axis driving mechanism 21 drives the temporary storage rack 22 to move to any buffer layer 221 and the conveying line 1 is at the same height; and the product on the conveying line 1 is placed in the buffer layer 221; and the two long edges of the product are limited by the limiting block 222 to ensure the stability of the product placed in the buffer layer 221.

[0039] As shown in Figure 1 Or Figure 6 The carrying assembly 3 comprises a Y-axis driving member 31 and a gripper 32 arranged on the Y-axis driving member 31. As shown in Figure 6As shown, the Y-axis drive unit 31 is slidably connected to a linear motion mechanism 311 via a mounting bracket. The output end of the linear motion mechanism 311 is fixedly connected to the gripper 32 via a connecting plate 312. The Y-axis drive unit 31 is preferably a linear module arranged along the Y-axis direction. Since linear modules are a known existing structure, they will not be described in detail here. The Y-axis drive unit 31 drives the gripper 32 to reciprocate between the conveyor line 1 and the temporary storage rack 22, placing the products on the conveyor line 1 onto the buffer layer 221 at the same height. Simultaneously, it can also grip products from the buffer layer 221 onto the conveyor line 1. The linear motion mechanism 311 drives the gripper 32 to rise and fall, allowing the gripper 32 to correspond to any of the buffer layers 221, thus facilitating the insertion of products into any of the buffer layers 221 or the gripping of products from any of the buffer layers 221 onto the conveyor line 1. The transport component and the temporary storage component work together. The temporary storage component moves relative to the transport component, allowing the grippers on the transport component and the product to be processed to be placed in any buffer layer of the temporary storage component. After placement, the grippers automatically move out of the temporary storage component, causing the temporary storage component to automatically move relative to the grippers to switch buffer layers.

[0040] Furthermore, the gripper 32 is positioned along the Z-axis and can move up and down relative to the Y-axis drive member 31. Specifically, as follows... Figure 6 As shown, the gripper 32 is mounted on a double-headed cylinder or two opposing one-way cylinders 321, and moves simultaneously toward or relative to each other; the upper surface of the cylinder 321 is fixed to the bottom of the connecting plate 312. Since the structures of the double-headed cylinder and the cylinder are known prior art, they will not be described in detail here.

[0041] Combination Figure 3 and Figure 6 As shown, a limiting plate 313 is provided on the outer side of the connecting plate 312. The limiting plate 313 is located between the two grippers 32 and is perpendicular to the setting direction of the grippers 32. During the product gripping process, the inner wall of the limiting plate 313 contacts the outer edge of the product, and when placed on the buffer layer 221, the limiting plate 313 limits the position of the outer edge of the product, effectively preventing the product from protruding from the limiting block 222 and causing the product to be unstable.

[0042] Further, the outer side of the connecting plate 312 is further provided with a sensor 314 for detecting whether there is a product on the gripper 32. The specific working process of moving the product from the conveying line 1 to the temporary storage assembly 2 is as follows: when the carrying assembly 3 receives the driving signal from the in-place sensor 123 or the alarm sensor 124, the Y-axis drive 31 and the linear moving mechanism 311 are started to drive the gripper 32 to approach the second conveying section 12, and after the sensor 314 detects the product, a start signal is sent to the cylinder 321 to drive the gripper 32 to clamp the product. Then the Y-axis drive 31 and the linear moving mechanism 311 drive the gripper 32 to move towards the direction of the infrared sensor 23 on the temporary storage assembly 2, and pause at the proximal end of the temporary storage rack 22, i.e. the outside of the opening of the temporary storage rack 22. At the same time, the temporary storage assembly 2 is started, and the Z-axis drive mechanism 21 drives the temporary storage rack 22 to move towards the gripper 32 until any buffer layer 221 of the temporary storage rack 22 is coaxial with the gripper 32. Then the infrared sensor 23 detects whether there is a product on the buffer layer 221 coaxial with its detection direction during the moving process. If the infrared sensor 23 detects that there is no product on the buffer layer 221, a temporary signal is sent to the Z-axis drive mechanism 21, and the gripper 32 is placed in the buffer layer 221 coaxial with it under the driving of the Y-axis drive 31; if the infrared sensor 23 detects that there is a product on the buffer layer 221, a continue moving signal is sent to the Z-axis drive mechanism 21 until a buffer layer without product is detected, and a temporary signal is sent to the Z-axis drive mechanism 21, and the gripper 32 is placed in the buffer layer 221 coaxial with it under the driving of the Y-axis drive 31.

[0043] The working process of moving the product from the temporary storage assembly 2 to the conveying line 1 is opposite to the above-mentioned working process, which will not be repeated here. In addition, if the infrared sensor 23 still does not detect a buffer layer without product when the temporary storage rack 22 moves to the limit position, the temporary storage rack 22 is driven in reverse by the Z-axis drive mechanism 21.

[0044] The utility model still has multiple implementation manners, all technical schemes formed by using equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
