Description

Technical Field

[0001] This invention relates to the field of rubber product manufacturing technology, specifically to an automated production line for rubber products. Background Technology

[0002] Current cable accessory production involves manual mold opening and closing, manual insertion and removal of glue guns, and manual transport into high-temperature ovens for vulcanization. This manual method is inefficient, labor-intensive, and results in inconsistent quality. Hydraulic flatbed vulcanizing equipment is only suitable for two-section molds that open and close vertically; the molds cannot be laid flat during vulcanization, making it unsuitable for three-section molds. Furthermore, continuous kinetic energy is required to keep the molds pressed during vulcanization. Therefore, we are introducing an automated production line for rubber products.

[0034] Example 1:

[0036] The upper middle part of the frame base 75 is provided with a transfer mechanism for transporting the rubber mold 71. The auxiliary lifting mechanism 72 is used to adjust the height of the middle mold of the rubber mold 71. The main lifting mechanism 74 is used to adjust the height of the upper mold of the rubber mold 71. The rotating mechanism 73 is used to lift the rubber mold 71 as a whole and rotate the rubber mold 71 at an angle.

[0037] An automated production line for rubber products also includes a cooling mold temperature controller 1, a heating mold temperature controller 2, a gantry robot 3, a glue injection machine 4, a material rack 5, and a control panel 6.

[0038] The molding machine 7 is located inside the gantry robot 3, and the material rack 5 is used to place the mandrel and finished product.

[0039] The transplanting mechanism is longitudinally positioned in the middle of the frame base 75, the auxiliary lifting mechanism 72 is transversely positioned above the middle of the frame base 75, the main lifting mechanism 74 is positioned above the tail of the frame base 75, the rotating mechanism 73 is positioned inside the main lifting mechanism 74, and the rubber mold 71 is a three-section rubber mold with an automatic locking mechanism, which includes an upper mold, a middle mold and a lower mold that can be automatically locked.

[0040] Example 2:

[0041] In this embodiment, such as Figure 2 As shown, the transplanting mechanism includes a linear guide rail 752 in the groove at the middle of the upper end of the frame base 75, a front transplanting base plate 751 and a rear transplanting base plate 754 slidably connected on the linear guide rail 752, and a first servo motor 755. The output end of the first servo motor 755 is provided with a ball screw 753. The ball screw 753 passes through the screw cylinder at the bottom of the rear transplanting base plate 754 and the front transplanting base plate 751, and the upper end of the front transplanting base plate 751 is provided with a transplanting seat 76 for placing the rubber mold 71.

[0042] Example 3:

[0043] In this embodiment, such as Figure 5-7 As shown, the auxiliary lifting mechanism 72 includes a second servo motor 721, a screw jack 722, and two sets of first optical axes 725 installed on both sides of the upper end of the frame base 75;

[0044] The top of the two sets of first optical axes 725 is connected to a fixed top plate 724. The second servo motor 721 drives a vertical lead screw 723 via a lead screw jack 722. The two sets of first optical axes 725 and the vertical lead screw 723 pass through a lifting plate 727.

[0045] The lifting plate 727 is provided with a lead screw nut and a first bearing cylinder 726. The lead screw nut is screwed to the outside of the vertical lead screw 723. The first optical shaft 725 passes through the first bearing cylinder 726. The top of the vertical lead screw 723 extends into the bearing on the lifting plate 727.

[0046] The upper inner side of the lifting plate 727 is provided with a clamping mechanism for clamping the rotating shaft portion 711 fixed on both sides of the rubber mold 71. This mechanism includes a clamping seat 7272 fixed to the upper inner side of the lifting plate 727, a cylinder 7271 fixed to the side of the clamping seat 7272, and a positioning pin 7274 connected to the output end of the cylinder 7271. The clamping seat 7272 has a placement groove 7273 for placing the rotating shaft portion 711. The cylinder 7271 drives the positioning pin 7274 to extend into the placement groove 7273, clamping the rotating shaft portion 711 and thus fixing the rubber mold 71. This improves the stability of the rubber mold 71 fixed on the auxiliary lifting mechanism 72, thereby ensuring the stability of the rubber mold 71 during lifting and lowering when the auxiliary lifting mechanism 72 adjusts the height of the rubber mold 71.

[0047] Example 4:

[0048] In this embodiment, such as Figure 9 As shown, the main lifting mechanism 74 includes a top frame 741 and two sets of third servo motors 743 fixed to the upper end of the top frame 741.

[0049] The lower corner of the top frame 741 is fixed to the upper end of the frame base 75 by a column 749, and two sets of second optical axes 746 are provided on the left and right sides of the lower end of the top frame 741, as well as a first trapezoidal lead screw 745 and a second trapezoidal lead screw 747 located between the two sets of second optical axes 746.

[0050] The top of the first trapezoidal lead screw 745 and the second trapezoidal lead screw 747 pass through the top frame 741 and are provided with pulleys, which are connected to the output end of the corresponding third servo motor 743 through a synchronous belt 744.

[0051] The second optical axis 746 on the same side passes through the second bearing cylinder on the upper mold lifting plate 748, the bottom of the first trapezoidal lead screw 745 passes through the trapezoidal nut on the upper mold lifting plate 748, and the bottom of the second trapezoidal lead screw 747 passes through the round hole on the upper mold lifting plate 748.

[0052] The third servo motor 743 is fixed on the motor mounting base 742 at the upper end of the top frame 741. The top frame 741 is also provided with a tensioning wheel 7441, which is in close contact with the surface of the timing belt 744.

[0053] Example 5:

[0054] In this embodiment, such as Figure 8As shown, the rotating mechanism 73 includes a first rotating shaft seat mounting plate 734, a second rotating shaft seat mounting plate 739, a first rotating shaft seat 738 mounted on the inner side of the upper end of the first rotating shaft seat mounting plate 734, a second rotating shaft seat 735 mounted on the inner side of the upper end of the second rotating shaft seat mounting plate 739, a driven turntable 7381 fixedly connected to the inner side of the driven rotating shaft in the first rotating shaft seat 738, and a driven turntable 736 fixedly connected to the inner side of the driven rotating shaft in the second rotating shaft seat 735.

[0055] Both the driven turntable 7381 and the driving turntable 736 have a mounting seat 7361 fixed on their inner sides for placing the rotating shaft 711;

[0056] The upper outer side of the first rotating shaft mounting plate 734 is fixed with a reducer mounting plate 7341 for mounting a worm gear reducer 733. The output end of the worm gear reducer 733 is connected to the drive shaft. The top of the worm gear reducer 733 is equipped with a fourth servo motor 731 through a planetary reducer 732. The fourth servo motor 731 drives the drive shaft to rotate through the planetary reducer 732 and the worm gear reducer 733.

[0057] The second optical axis 746 is fixed to the upper end of the frame base 75 after passing through the third bearing cylinder 737 at the lower end of the first shaft mounting plate 734 and the second shaft mounting plate 739. The bottom of the first trapezoidal lead screw 745 is inserted into the bearing of the frame base 75 after passing through the round holes on the first shaft mounting plate 734 and the second shaft mounting plate 739. The bottom of the second trapezoidal lead screw 747 is inserted into the bearing of the frame base 75 after passing through the trapezoidal nuts on the first shaft mounting plate 734 and the second shaft mounting plate 739.

[0058] Specifically, during use, when the mold is closed, the transfer mechanism transports the lower mold to the position of the auxiliary lifting mechanism 72, that is, the lower mold is placed on the transfer seat 76. Then, the first servo motor 755 drives the front transfer base plate 751 and the transfer seat 76 to move through the ball screw 753. The front transfer base plate 751 moves along the linear guide rail 752 until the lower mold on the transfer seat 76 moves to the auxiliary lifting mechanism 72.

[0059] The auxiliary lifting mechanism 72 lowers the middle mold onto the lower mold, and the middle mold and the lower mold lock themselves together. That is, the rotating shaft 711 on the middle mold is placed in the placement groove 7273 on the clamping seat 7272. The cylinder 7271 drives the positioning pin 7274 to extend into the placement groove 7273 and clamp the rotating shaft 711 to fix the middle mold. Then, the second servo motor 721 drives the vertical screw 723 to rotate through the screw jack 722, so that the vertical screw 723 drives the lifting plate 727 to move down along the front and rear first optical axes 725. The middle mold moves down and the bottom of the middle mold contacts the upper end of the lower mold until the middle mold and the lower mold lock themselves together.

[0060] The transplanting mechanism then transports the lower mold and the middle mold to the position of the main lifting mechanism 74. The main lifting mechanism 74 lowers the upper mold onto the middle mold, and the middle mold and the upper mold are automatically locked together. That is, the cylinder 7271 drives the positioning pin 7274 to retract and reset. The second servo motor 721 drives the vertical screw 723 to rotate through the screw jack 722, so that the vertical screw 723 drives the lifting plate 727 to move down along the front and rear first optical axes 725 until the rotating shaft 711 is disengaged from the placement groove 7273.

[0061] The first servo motor 755 drives the front transplant base plate 751 and the transplant seat 76 to move backward via the ball screw 753. The front transplant base plate 751 moves backward along the linear guide rail 752 until the lower mold and the middle mold on the transplant seat 76 are transported to the position of the main lifting mechanism 74.

[0062] The upper end of the upper mold is supported on both sides of the upper mold lifting plate 748. The corresponding third servo motor 743 drives the first trapezoidal lead screw 745 to rotate through the synchronous belt 744, so that the first trapezoidal lead screw 745 drives the upper mold lifting plate 748 to move down along the second optical axis 746, lowering the upper mold onto the middle mold until the upper mold and the middle mold automatically lock together to form a rubber mold 71.

[0063] The rotating mechanism 73 lifts the rubber mold 71 (the entire mold) and flips the rubber mold 71 at a certain angle. The corresponding third servo motor 743 drives the second trapezoidal lead screw 747 to rotate through the synchronous belt 744. This causes the second trapezoidal lead screw 747 to drive the first rotating shaft mounting plate 734 and the second rotating shaft mounting plate 739 to move upward along the second optical axis 746 until the rotating shaft part 711 is inserted into the placement seat 7361. At this time, the first rotating shaft mounting plate 734 and the second rotating shaft mounting plate 739 continue to move upward, lifting the rubber mold 71.

[0064] Subsequently, the fourth servo motor 731 drives the active rotating shaft to rotate through the planetary reducer 732 and the worm gear reducer 733. The active rotating shaft drives the active turntable 736 and the placement seat 7361 to rotate, thereby causing the rubber mold 71 to flip at a certain angle and change the posture of the rubber mold 71 to a horizontal position. At this time, the mold closing is completed, and the mold can be injected with rubber and vulcanized.

[0065] When the mold is opened, the rotating mechanism 73 flips the rubber mold 71 at a certain angle, changing its posture to vertical, and lowers the rubber mold 71 onto the transplanting seat 76 of the transplanting mechanism. The middle mold and the upper mold automatically open the locking mechanism. That is, the fourth servo motor 731 drives the active rotating shaft to rotate through the planetary reducer 732 and the worm gear reducer 733. The active rotating shaft drives the active turntable 736 and the placement seat 7361 to rotate, thereby causing the rubber mold 71 to flip at a certain angle, changing its posture to vertical.

[0066] Then, the corresponding third servo motor 743 drives the second trapezoidal lead screw 747 to rotate via the synchronous belt 744, causing the second trapezoidal lead screw 747 to drive the first rotating shaft mounting plate 734 and the second rotating shaft mounting plate 739 to move downward along the second optical axis 746. The middle mold and the upper mold automatically open the locking mechanism until the middle mold and the lower mold of the rubber mold 71 descend onto the transplanting seat 76 of the transplanting mechanism, and the rotating shaft part 711 disengages from the placement seat 7361.

[0067] The main lifting mechanism 74 raises the upper mold to a certain height, and the transfer mechanism transports the middle and lower molds to the position of the auxiliary lifting mechanism 72. At this time, the workpiece can be removed from the mold. The middle and lower molds automatically open their locking mechanisms. The auxiliary lifting mechanism 72 raises the middle mold to a certain height, and the transfer mechanism transports the lower mold to the front end of the frame base 75, completing the mold opening. The corresponding third servo motor 743 drives the first trapezoidal lead screw 745 to rotate via the synchronous belt 744. This causes the first trapezoidal lead screw 745 to drive the upper mold lifting plate 748 to move upwards along the second optical axis 746, raising the upper mold to a certain height. The first servo motor 755 drives the front transfer base plate 751 to move along the linear guide rail 752 via the ball screw 753 until the middle and lower molds on the transfer seat 76 are transported to the position of the auxiliary lifting mechanism 72. At this time, the workpiece can be removed from the mold. The middle and lower molds automatically open their locking mechanisms. The second servo motor 721 drives the vertical lead screw 723 to rotate via the lead screw jack 722. The vertical lead screw 723 drives the lifting plate 727 to move upward along the two sets of first optical axes 725, so that the rotating shaft 711 on the middle mold is placed in the placement groove 7273 on the clamping seat 7272. The cylinder 7271 drives the positioning pin 7274 to extend into the placement groove 7273 and clamp the rotating shaft 711 to fix the middle mold. The lifting plate 727 continues to move upward, raising the middle mold to a certain height. Then, the first servo motor 755 drives the front transfer base plate 751 to move forward along the linear guide rail 752 through the ball screw 753 until the lower mold on the transfer seat 76 moves to the front end of the frame base 75, and the mold opening is completed.

[0068] The molding machine 7 automatically opens the rubber mold 71. The gantry robot 3 transfers the mandrel into the rubber mold 71 at the material rack 5. The molding machine 7 then closes the rubber mold 71 and flips it to a horizontal position. The glue injection machine 4 injects glue into the rubber mold 71. The temperature riser 2 raises the temperature of the rubber mold 71 to the set temperature to vulcanize the glue. After vulcanization, the molding machine 7 opens the rubber mold 71. The gantry robot 3 removes the finished product from the rubber mold 71 and places it in the material rack 5. One cycle is completed. All equipment operations are centralized at the control panel 6.
