[0050] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims. Example

[0051] A fully automated metal-rubber component node removal system, such as Figure 1 As shown, the system includes a base 100 standing on the ground, a node conveying assembly 200 placed on the base 100, and a press 300 suspended above the node conveying assembly 200. The metal and rubber parts are placed on the node conveying assembly 200. It also includes a climbing assembly 400 and a press working boss 500, and as shown... Figure 2 and 3As shown, the node conveying assembly 200 includes a mounting frame 210, a conveying line I 220 and a node stripping tool plate 230, the mounting frame 210 is placed on the base 100, the conveying line I 220 is installed on the mounting frame 210, the node stripping tool plate 230 is placed on the conveying line I 220, the press working boss 500 is fixed with the base 100 and located directly below the press 300; the climbing assembly 400 is arranged in pairs on both sides of the mounting frame 210. As shown in Figure 3 As shown, the embodiment includes two pairs of climbing assemblies 400, and the four climbing assemblies 400 are arranged near the end of the conveying line I 220. When the conveying line I 220 conveys the product, the climbing assembly 400 lifts the mounting frame 210, and the node stripping tool plate 230 is located higher than the press working boss 500; when the conveying line I 220 conveys the node stripping tool plate 230 directly below the press 300, the climbing assembly 400 drives the mounting frame 210 to descend, the press working boss 500 is higher than the conveying line I 220, and the node stripping tool plate 230 falls on the press working boss 500.

[0052] Specifically, as shown in Figure 4 The climbing assembly 400 includes a driving device I 410, a climbing boss seat 420 and a climbing cam 430, the driving device I 410 is installed on the base 100, the climbing boss seat 420 is fixed with the output end of the driving device I 410, and the climbing cam 430 is fixed on the side surface of the mounting frame 210; the climbing boss seat 420 is provided with an inclined hole 421, both ends of the inclined hole 421 are circular holes with a size suitable for the climbing cam 430, and the vertical distance between the centers of the circular holes at both ends of the inclined hole 421 is the descending distance h of the mounting frame 210 (as shown in Figure 6 The driving device I 410 drives the climbing boss seat 420 to translate, so that the climbing cam 430 moves in the inclined hole 421, the climbing cam 430 switches between the highest end and the lowest end of the inclined hole 421, the mounting frame 210 is lifted off the base 100 or located on the base 100, and the climbing cam 430 is rotatable. As shown in Figure 4 The driving device I 410 is installed on the base 100 through an L-shaped seat 440, the output end of the driving device I 410 is connected with an adapter plate I 450, one side of the adapter plate I 450 is fixed with the climbing boss seat 420, the opposite side is provided with a guide rail 460, the opposite side of the guide rail 460 is provided with a sliding block fixing vertical plate 470, the sliding block fixing vertical plate 470 is fixed with the base 100, and the sliding block fixing vertical plate 470 is provided with a sliding block matched with the guide rail 460. When the driving device I 410 drives the climbing boss seat 420 to translate, the guide rail 460 and the sliding block are used for guiding.

[0053] The climbing assembly 400 can also be a cylinder, respectively located on both sides of the mounting frame 210, but the length of the cylinder on both sides can not be completely equal, resulting in the lifting of the mounting frame 210 is not stable. The present application is carefully designed for the climbing assembly 400, the structure of the inclined hole and the cam is matched, the relative movement of the inclined hole and the cam is adopted, and the climbing assembly 400 arranged on both sides of the mounting frame 210 can stably lift and lower the mounting frame 210 by using a simple structure. The specific process is: when the conveying line 220 is conveying products, the climbing cam 430 is located in the lower end of the inclined hole 421, and the mounting frame 210 is lifted. When the products conveyed by the conveying line 220 are located below the press 300, the driving device 410 drives the climbing cam seat 420 to move linearly, so that the climbing cam 430 moves along the inclined hole 421, forcing the climbing cam 430 to enter the higher end of the inclined hole 421, so that the mounting frame 210 is lowered, that is, the whole node conveying assembly 200 is lowered, and the node stripping tool plate 230 placed on the conveying line 220 falls on the press working cam 500, and the conveying line 220 and the mounting frame 210 fall below the surface of the press working cam 500. In this case, when the press 300 is stripping the products on the node stripping tool plate 230, the pressure of the press 300 acts on the press working cam 500, and does not affect the conveying line 220 and the mounting frame 210.

[0054] In order to ensure the smooth realization of the relative movement of the inclined hole 421 and the climbing cam 430, the climbing assembly 400 further comprises a weight reduction assembly 480; the climbing cam 430 is fixed with the mounting frame 210 through the reinforcing plate 490; the weight reduction assembly 480 is located below the reinforcing plate 490 and is fixed with the reinforcing plate 490. When the driving device 410 drives the climbing cam seat 420 to move linearly, the weight reduction assembly 480 provides a vertical force to the climbing cam 430, so as to achieve the effect of reducing the weight, and the climbing cam 430 smoothly enters the other hole of the inclined hole 421. As shown in Figure 5 The weight reduction assembly 480 comprises a driving device 481, a guide rod 482 and an adapter plate 483, the driving device 481 is installed on the base 100, the center of the adapter plate 483 is fixed with the output end of the driving device 481, and the adapter plate 483 is fixed with the reinforcing plate 490 at the same time; the two ends of the adapter plate 483 are respectively fixed with a guide rod 482, and the guide rod 482 is movably arranged through the base 100. In use, when the driving device 410 drives the climbing cam seat 420 to move linearly, the driving device 481 provides a vertical force upward, which offsets part of the gravity of the node conveying assembly 200, so that the climbing cam 430 more easily enters the other hole of the inclined hole 421.

[0055] In order to ensure the balance of the product during stamping, as shown in Figure 3 and Figure 4As shown, a node stripping tool plate support seat 600 is also installed on the base 100, and the node stripping tool plate support seat 600 is the same height as the press working boss 500. Figure 10 As shown, the node stripping tool plate support seat 600 is a structural schematic diagram. When the node conveying assembly 200 is lifted by the climbing assembly 400, the node stripping tool plate support seat 600 and the press working boss 500 are both below the node stripping tool plate 230; when the node conveying assembly 200 is lowered by the climbing assembly 400, the node stripping tool plate 230 falls together and falls on the node stripping tool plate support seat 600 and the press working boss 500, and the node stripping tool plate support seat 600 and the press working boss 500 jointly support the product to ensure the stability of the product during node stripping.

[0056] In order to ensure that the conveying line 220 accurately conveys the node of the product to the position directly below the press 300, as shown, Figure 3 and 8 As shown, a horizontal blocking 700 is also installed on the base, as shown, Figure 9 As shown, the horizontal blocking 700 includes a blocking edge 710, a third driving device 720, and a movable blocking structure, the blocking edge 710 is fixed to the base 100, the third driving device 720 and the movable blocking structure are installed on the blocking edge 710, the third driving device 720 drives the movable blocking structure to extend upward to block the node stripping tool plate 230, and the node stripping tool plate 230 is provided with a horizontal blocking extension hole 231 for the horizontal blocking 700 to extend. The movement, stop, and speed of the conveying line of the present application are controlled by a control system.

[0057] As shown, Figure 9 The blocking edge 710 includes a left blocking edge and a right blocking edge, the third driving device 720 and the movable blocking structure are arranged between the left blocking edge and the right blocking edge, the movable blocking structure includes a connecting shaft, a movable plate 732, and a blocking roller 740, the connecting shaft is rotationally connected with the movable plate 732, and the movable plate 732 is arranged in pairs at both ends of the connecting shaft; the connecting shaft includes a first-level connecting shaft a, a second-level connecting shaft b, a third-level connecting shaft c, and a fourth-level connecting shaft d, which are arranged in parallel, the movable plate 732 includes a first-level movable plate 732a, a second-level movable plate 732b, and a third-level movable plate 732c; the first-level connecting shaft a and the fourth-level connecting shaft d are fixed between the left blocking edge and the right blocking edge, and the first-level connecting shaft a, the first-level movable plate 732a, the second-level connecting shaft b, the second-level movable plate 732b, the third-level connecting shaft c, the third-level movable plate 732c, and the fourth-level connecting shaft d are connected in sequence; the output end of the third driving device 720 is fixedly connected with the second-level connecting shaft b, and the blocking roller 740 is fixed with the third-level connecting shaft c; the third-level movable plate 732c is L-shaped, when the output end of the third driving device 720 extends, one side of the L-shaped third-level movable plate 732c protrudes upward higher than the blocking edge 710 and is perpendicular to the installation plane of the horizontal blocking 700. As shown, Figure 9As shown, there are pairs of first-level movable plates 732a, second-level movable plates 732b, and third-level movable plates 732c, which are respectively set at both ends of the four connecting shafts.

[0058] The horizontal blocking roller 700 is flexible and retractable. The secondary connecting shaft b, fixed to the output end of the drive device 720, is analogous to a person's knee. When the conveyor line 220 is moving, the drive device 720 pushes the secondary connecting shaft b outward. The secondary connecting shaft b drives the connected primary movable plate 732a and secondary movable plate 732b outward, causing them to rotate and lower their vertical position. This lowers the position of the tertiary connecting shaft c, allowing the blocking roller 740 to retract. When the conveyor line 220 reaches the system-set position and needs to stop, the blocking roller 740 extends from the mounting bracket 210, and the output end of the drive device 720 retracts. Due to the constraint of the L-shaped tertiary movable plate 732c, the primary movable plate 732a and secondary movable plate 732b are perpendicular to the machine base 100, allowing the blocking roller 740 to extend and move along the blocking retraction node tooling plate 230. Figure 3 As shown, a rectangular hole 231 is provided on the retraction node tooling plate for the blocking roller 740 of the horizontal blocking 700 to extend out.

[0059] like Figure 3 As shown, the mounting frame 210 has a rectangular frame 211. An inner sealing plate 212 is fixed between the two long sides of the rectangular frame 211. A groove 213 is provided between the inner sealing plate 212 and the long sides to accommodate the chain of the conveyor line 220. The inner sealing plate 212 is located above the machine base 100. The press working boss 500, the retraction node tooling plate support 600, and the horizontal block 700 mentioned above are all fixed on the machine base 100 and do not rise or fall with the mounting frame 210, nor do they move with the conveyor line 220. However, they all protrude upward from the inner sealing plate 212 because corresponding positions on the inner sealing plate 212 have a boss protrusion hole 232 for the press working boss 500 to protrude, a support protrusion hole 233 for the retraction node tooling plate support 600 to protrude, and a horizontal block protrusion hole 231 for the horizontal block 700 to protrude.

[0060] like Figure 11As shown, the press 300 comprises a support frame, a driving device six 320 mounted on the support frame, and a pressure head 330 connected to the output end of the driving device six 320, the driving device six 320 drives the pressure head 330 to descend; the support frame comprises a driving device six mounting plate 311, a guide plate 312, a column 313 and a column mounting plate 314; the column mounting plate 311 is mounted on the base 100, the column 313 is supported between the driving device six mounting plate 311 and the column mounting plate 314, the driving device six 320 is mounted on the driving device six mounting plate 314, and the guide plate 312 is also connected to the output end of the driving device six 320, the guide plate 312 takes the column 313 as a guide rod, and the driving device six 320 drives the guide plate 312 to slide along the column 313.

[0061] The above design not only uses mechanical equipment to replace manual work, reduces labor intensity, and improves production efficiency, but also ingeniously designs the climbing assembly and the press working boss, so that the pressure does not act on the conveying line when the press is in the pressure withdrawal point, solving the technical problem that the prior art does not have practicality. The prior art also has the deficiency that the recovery of the waste node still relies on manual operation and has not been fully realized.

As shown in Figure 15 As shown, the support seat 843 is U-shaped, like two hands holding the old node tool plate 830 upward. A buffer pad is also installed on the top of the U-shaped support seat 843.

[0067] The guide plate is square, and a reinforcing rib is further fixed between the guide plate and the sliding plate.

[0068] The guiding and centering assembly 850 of the present application, when the old node falls down, two pairs of guiding plates 853 move towards each other to approach the old node, and first coarsely position the old node, playing a guiding role; after the old node falls on the old node tool plate 830, the two pairs of guiding plates 853 continue to move towards each other until the two pairs of guiding plates 853 are in contact with the old node, clamping the old node and centering the old node, at this time the old node is accurately moved into the mounting hole 831 of the old node tool plate 830, completing fine positioning. After the node is centered in the positioning hole of the tool plate, the guiding and centering assembly is loosened, and the lifting assembly is lowered, so that the tool plate is located on the conveying line two.

[0069] The guiding and centering assembly adjusts the distance between the two pairs of guiding plates through the driving device five to adapt to nodes of different sizes.

[0070] The old node tool plate 830 is square, and the mounting hole 831 is formed in the center of the direction, the diameter of the mounting hole 831 is greater than the outer diameter of the old node core shaft and less than the outer diameter of the old node rubber part; semicircular holes are also formed on both sides of the mounting hole 831 to facilitate the robot to grab the old node tool plate 830.

[0071] As shown in Figure 7 and Figure 13 The conveying line one 220 and the conveying line two 820 each include two groups of driving components A and two conveying belts B, the two groups of driving components A of the conveying line one 220 are respectively installed at two ends of the node conveying assembly mounting frame 210, and the two groups of driving components A of the conveying line two 820 are respectively installed at two ends of the old node recycling assembly base 810, the driving component A sequentially includes a driving device seven A1, a driving wheel A2, a driven wheel A3, a short shaft A4, a synchronous belt A5 and a long shaft A6 which are in transmission connection; the driving wheel A2 is connected with the output end of the driving device seven A1, and the driving wheel A2 and the driven wheel A3 are in transmission connection; the driven wheel A3 is centrally provided with a one-way clutch A7, one end of the short shaft A4 is connected with the one-way clutch A7, and the other end is connected with the synchronous belt A5, and the synchronous belt A5 is in transmission connection with the long shaft A6; the long shaft A6 is in transmission connection with one conveying belt B at each end; the old node tool plate 230 (or the old node tool plate 830) is erected on the two conveying belts B; two driving device sevens A1 control the forward and reverse rotation of the conveying belt B. In the embodiment, the driving wheel A2 and the driven wheel A3 are both sprockets, which are in transmission connection through a chain. The conveying belt B is a chain.

[0072] The reason for the two groups of driving components A of the conveying line one 220 and the conveying line two 820: the conveying line one 220 or the conveying line two 820 (collectively referred to as the conveying line) in the present application can be installed with a driving device seven A1 and its transmission components on one side of the middle part of the conveying line conveying belt B, and one driving device seven A1 can simultaneously realize the forward and reverse rotation of the conveying belt B. However, the press, the protective cover, the inductor, the electrical equipment and the like need to be installed on the machine base 100, so that the driving components installed in the middle part of the conveying line B will interfere with other components, and therefore the driving components A are installed at both ends to avoid interference with other components. When the driving components A are installed at both ends, if only one group of driving components A is used, due to the long conveying belt B (chain), the chain will be knotted, for example: when the motor rotates forward, the chain is pulled away, when the motor reverses, the chain is pushed away, the chain will be loose, which may cause the upper layer of the chain to be tight and the lower layer to be loose, resulting in knotting and abnormal noise. The present application provides one group of driving components at both ends of the conveying belt chain, respectively controlling the forward and reverse rotation of the two conveying belts, as shown in the drawings, the two groups of driving components are located at both ends of the conveying belt and are located on different sides. It should be noted that, as shown in Figure 20 the driving device seven A1 on one side rotates, the one-way clutch A7 is locked, the power of the driving wheel A2 is transmitted to the long shaft A6 through the driven wheel A3, the short shaft A4 and the synchronous belt A5, and the long shaft A6 is also fixed with a sprocket at both ends, which meshes with the conveying belt B chain to drive the two conveying belts B to rotate. At this time, the driving device seven A1 of the driving component on the other side does not rotate, and the one-way clutch A7 of the driving component on the other side is in the "off" state. The power from the long shaft to the short shaft cannot be transmitted to the driven wheel A3, so it will not affect the driving device seven A1.
