[0041] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0042] like Figure 1-Figure 6 As shown, the utility model discloses a non-stop automatic material sorting and discharging stamping production system, comprising an upper mold 1, a lower mold 2, and a lifting and conveying mechanism 3; a vertically penetrating punching hole 21 is provided on the lower mold 2, and an upper material limiting component 41 and a lower material limiting component 42 are provided on the lower mold 2; the lifting and conveying mechanism 3 is located below the punching hole 21, and the lifting and conveying mechanism 3 is lifted up and down to approach or move away from the punching hole 21; wherein, the upper mold 1 punches toward the lower mold 2 to punch out a workpiece 92 whose shape and size match the punching hole 21 on a substrate, the upper material limiting component 41 and the lower material limiting component 42 are both located in the lower mold 2, and the upper material limiting component 41 is on the top and the lower material limiting component 42 is on the bottom, so that the upper material limiting component 41 works to limit the workpiece 92 dropped into the punching hole 21 from moving toward the lower material limiting component 42, and the lower material limiting component 42 works to limit the workpiece 92 dropped into the punching hole 21 from falling out of the punching hole 21 downward.

[0043] Among them, the base material used in this embodiment is a strip 91, which is packaged in a roll shape and is pulled out in a strip shape under the action of the waste winding mechanism and passes between the upper mold 1 and the lower mold 2. Under the downward punching action of the upper mold 1, the strip 91 is punched out to form a workpiece 92 with the same shape and size as the punching hole 21.

[0044] The lifting and conveying mechanism 3 is a mechanism in which a conveyor belt is installed on a lifting frame, and the lifting frame is installed on a frame along a vertical sliding direction, and the lifting frame is slid up and down by a cylinder, thereby driving the conveyor belt to approach or move away from the punching hole 21 .

[0045] Therefore, in the initial state, it is set so that the upper blanking limiting component 41 is in a blanking state of non-restricted punching hole 21, and the lower blanking limiting component 42 is in a blanking state of restricted punching hole 21, and then the substrate is conveyed between the upper mold 1 and the lower mold 2, and the upper mold 1 punches downward so that the workpiece 92 with the same shape and size as the punching hole 21 is punched into the punching hole 21, and is stacked at the lower blanking limiting component 42 under the restriction of the lower blanking limiting component 42. After stacking to a certain number, the conveyor belt of the lifting and conveying mechanism 3 is driven to rise to approach the lower end of the punching hole 21, and then the upper blanking limiting component 41 is driven at the same time to restrict the blanking of the punching hole 21, and the lower blanking limiting component 42 is released from restricting the blanking of the punching hole 21, so that the workpiece 92 formed by the non-stop punching of the upper mold 1 is temporarily stacked at the upper blanking limiting component 41 under the restriction of the upper blanking limiting component 41, and the workpiece 92 stacked by the lower blanking limiting component 42 continues to move downward along the punching hole 21 and falls on the lifting and conveying mechanism 3. The conveyor belt of the lowering conveyor mechanism 3 is then driven to lower the conveyor belt of the lifting conveyor mechanism 3 so that the workpieces 92 stacked on the conveyor belt are completely out of the punching hole 21, so that the conveyor belt conveying work can stably transfer the stacked workpieces 92, so that punching and material sorting can be carried out simultaneously to achieve optimal production efficiency, and the sorted workpieces 92 can be more convenient for subsequent packaging and secondary processing. In addition, the workpieces 92 are all in flat contact, and the contact surface is larger to ensure that the edges and corners of the workpieces 92 are not deformed by impact and impact pits are not formed on the surface of the workpieces 92 during stacking and transportation, so as to protect the workpieces 92 and improve the yield rate. In addition, after the workpieces 92 fall onto the conveyor belt, the lower material limiting component 42 is driven to limit the material falling of the punching hole 21 at the same time, and the upper material limiting component 41 is released to limit the material falling of the punching hole 21, so that the workpieces 92 temporarily stacked on the upper material limiting component 41 fall to the lower material limiting component 42 and continue to be stacked and counted, so that the upper mold 1 does not need to stop working and further improves the production efficiency.

[0046] In other embodiments, a plate may be used as the substrate, so that the plate is placed between the upper mold 1 and the lower mold 2 for punching manually or by a robot, and after the punching is completed, the waste material is removed and the plate is replaced.

[0047] Specifically, the upper material drop limiting assembly 41 and the lower material drop limiting assembly 42 in the present embodiment both include a telescopic cylinder 5, a connecting frame 6 and a limit member 7.

The telescopic cylinder 5 is fixedly mounted on the lower mold 2 by means of bolts, and the output shaft of the telescopic cylinder 5 and the connecting frame 6 are threadedly fixedly connected so as to drive the connecting frame 6 to slide under the operation of the telescopic cylinder 5; wherein, the sliding channel 22 and the punching hole 21 are connected so that the limit member 7 is driven to extend into the punching hole 21 to limit the workpiece 92 from falling, and the limit member 7 is driven to escape from the punching hole 21 to release the restriction on the falling of the workpiece 92.

[0048] Preferably, the limiting member 7 in this embodiment is provided with a material handling surface 71 on the side facing the punching hole 21, and the shape of the material handling surface 71 is adapted to the shape of the punching hole 21; in addition, the limiting member 7 is provided with a support portion 72 protruding toward the punching hole 21 at the lower end of the material handling surface 71.

[0049] Therefore, the falling workpieces 92 are stacked more evenly under the action of the material sorting surface 71 , while the stability of the stacking is ensured under the action of the supporting portion 72 .

[0050] Preferably, the support portion 72 in this embodiment is arranged in a strip shape, and the shape of the support portion 72 is adapted to the shape of the material processing surface 71, so that the long strip-shaped support portion 72 can provide more stably support for the workpiece 92, and the length direction of the long strip-shaped support portion 72 extends along the shape of the outer peripheral wall of the material processing surface 71, so that the limit member 7 only needs to move a distance adapted to the width of the support portion 72 to extend into the punching hole 21 or escape from the punching hole 21.

[0051] In addition, the upper end of the material-sorting surface 71 in this embodiment is provided with a material-guiding inclined surface 711 that is inclined downward in the direction toward the punching hole 21 , so that the falling workpiece 92 can land on the material-sorting surface 71 more smoothly.

[0052] In addition, a supporting plane 721 is provided at the upper end of the supporting portion 72 in this embodiment, so that the support is more stable.

[0053] In addition, the lower end of the support portion 72 in this embodiment is provided with an anti-pinch slope 722 that is inclined upward along the direction of the punching hole 21, so that when the workpiece 92 falls downward and is stuck in the punching hole 21, the workpiece 92 can be pushed downward for blanking when the limit member 7 re-enters the punching hole 21.

[0054] Specifically, the punching hole 21 in this embodiment is in the shape of a runway, and the material handling surface 71 is an arc surface adapted to the arc segment of the punching hole 21, so that the workpiece 92 can be better aligned and adjusted under the action of the material handling surface 71, thereby improving the flatness of the stacking of the workpieces 92.

[0056] Preferably, the punching holes 21 in the present embodiment include 4 first hole bodies 211 and 3 second hole bodies 212, the arrangement directions of the first hole bodies 211 and the second hole bodies 212 are both along the left-right direction, and the second hole body 212 is located at the rear side between two adjacent first hole bodies 211, wherein the left-right width of the first hole body 211 and the second hole body 212 is s1, and the spacing between adjacent first hole bodies 211 and the spacing between adjacent second hole bodies 212 are s2, wherein s1≥s2, so that a single punching can be used to process multiple workpieces 92, and the orderly arrangement of the first hole bodies 211 and the second hole bodies 212 makes the compactness better; in addition, the upper and lower material drop limiting components 41 and 42 each have 4 connecting frames 6, wherein two corresponding connecting frames 6 limit four punching holes 21, corresponding to the two first hole bodies 211 and the two second hole bodies 212 respectively, and the other two corresponding connecting frames 6 limit three punching holes 21 , respectively corresponding to two first hole bodies 211 and one second hole body 212. Specifically, each connecting frame 6 includes a main connecting rod 63 and one or two sub-connecting rods 64. The number of sub-connecting rods 64 on the connecting frame 6 is the same as the number of first hole bodies 211 corresponding to the connecting frame 6, or the number of sub-connecting rods 64 on the connecting frame 6 is the same as the number of second hole bodies 212 corresponding to the connecting frame 6. In addition, the limiting member 7 connected to the connecting frame 6 includes a first functional member 75 and a second functional member 76.

Among them, the two main connecting rods 63 are located at the front side of the first hole body 211 and the second hole body 212, and the two main connecting rods 63 are located at the rear side of the first hole body 211 and the second hole body 212, so that the distance between the first hole body 211 and the second hole body 212 is more compact.

[0057] Therefore, the telescopic cylinder 5 drives the main connecting rod 63, and simultaneously drives the plurality of first functional parts 75 and the second functional parts 76, so that the number of driving sources is reduced and the whole is more synchronized.

[0058] Correspondingly, the lifting and conveying mechanism 3 in this embodiment includes a first conveyor belt 31 and a second conveyor belt 32.
