Description

Technical Field

[0001] The embodiments of the present invention relate to the field of bulletproof helmet processing technology, specifically, to an automated production line for processing bulletproof helmets. Background Technology

[0002] Bulletproof helmets are a primary military product used to protect the user's head. The main materials of bulletproof helmets are ultra-high molecular weight polyethylene fiber and aramid fiber. Ultra-high molecular weight polyethylene fiber is used to produce the main body of the bulletproof helmet, and multiple layers of aramid fiber are added to the helmet body to improve the protection of the user's head.

[0003] In the production and manufacturing process of bulletproof helmets, laser die-cutting machines and hot pressing equipment are used. First, the laser die-cutting machine is used to sequentially die-cut a whole piece of aramid fiber into different shapes. Then, the shaped helmet body is placed on the lower mold of the hot pressing equipment. Then, the workers place each layer of aramid fiber onto the helmet body, and start the hot pressing equipment to drive the upper mold to descend, so that the aramid fiber and the helmet body are hot-pressed together. Using the above method, multiple layers of aramid fiber are sequentially processed onto the helmet body to complete the production and manufacturing of bulletproof helmets.

[0004] Because the shape of each layer of aramid fiber placed on the helmet body varies during the manufacturing process of bulletproof helmets, it is crucial to ensure that the aramid fiber layer is placed correctly. Current technology uses pneumatic clamps to grip the die-cut aramid fiber layer using vacuum adsorption. However, when using pneumatic clamps, the aramid fiber layer must be kept absolutely flat for effective adsorption. During the placement of the aramid fiber layer onto the helmet body, because the aramid fiber layer is flat while the helmet body is curved, the aramid fiber may shift as it falls onto the helmet body after the pneumatic clamps stop adsorbing it. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide an automated production line for processing bulletproof helmets, which solves the technical problem in the related art where aramid fiber displacement easily occurs when the die-cut aramid fiber layer is moved onto the helmet body during the production process of bulletproof helmets.

[0006] This invention provides an automated production line for processing bulletproof helmets, comprising a production line frame, which includes a die-cutting frame, a gripping frame, and a hot press frame. The die-cutting frame is equipped with die-cutting equipment, and the hot press frame is equipped with a top hot press structure. The production line also includes:

[0007] The lifting slide is provided with an XY axis moving device between the lifting slide and the gripping frame. The bottom of the lifting slide is longitudinally moved with a lifting seat. Multiple adsorption clamps are provided on the outside of the lifting seat. The multiple adsorption clamps are grouped in pairs.

Multiple abutment seats are provided on the top of the mounting cylinder seat. The multiple abutment seats are grouped in pairs, and each abutment seat corresponds to one of the adsorption clamps. The mounting cylinder seat is provided with a position adjustment structure to adjust the position of the multiple abutment seats.

[0009] A forming base is movably mounted on the hot press frame. A lower punch is provided on the top of the forming base, and multiple rectangular inlets and outlets are provided on the top of the forming base for the abutment seat to extend out.

[0010] To further adjust the position of multiple adsorption clamps, the sliding adjustment structure includes a through groove, a triangular connector, and a circumferential drive structure. Multiple through grooves are fixedly connected to the bottom circumference of the lifting seat. A T-shaped sliding body is slidably connected to each through groove. Two adsorption clamps are respectively disposed on both sides of the T-shaped sliding body. The triangular connector is fixedly connected to the T-shaped sliding body. An inclined groove is formed on the triangular connector, and a rotating component is slidably disposed on the inclined groove. The circumferential drive structure is provided at the bottom of the lifting seat for moving the multiple triangular connectors.

[0011] To move the multiple triangular connectors, the circumferential drive structure further includes a lifting ring and a first electric cylinder. The lifting ring is slidably sleeved on the bottom of the lifting seat, and multiple connecting rods are fixedly connected to the bottom circumference of the lifting ring. The connecting rods are rotatably connected to the rotating component. The first electric cylinder is mounted on the lifting slide block, and the output end of the first electric cylinder is fixedly connected to the lifting ring.

[0012] To further adsorb aramid fibers, an annular suction cylinder is fixedly connected to the bottom of the lifting slide, and a suction pipe is connected between the adsorption clamp and the annular suction cylinder. An adsorption device is provided on the lifting slide, and the adsorption device is connected to the annular suction cylinder.

[0013] To further facilitate the upward movement of the mounting base, a sliding seat is slidably connected within the transverse sliding groove frame. A second electric cylinder is mounted on the top of the sliding seat, and the output end of the second electric cylinder is fixedly connected to the bottom end of the mounting base.

[0014] To further adjust the position of the multiple abutment seats, the position adjustment structure includes a fixed slide groove and a threaded adjustment component. The inner circumference of the mounting cylinder is fixedly connected with multiple fixed slide grooves, and T-shaped sliding bodies are also slidably arranged on the fixed slide grooves. Two abutment seats are respectively fixedly connected to the top two sides of the T-shaped sliding bodies. The threaded adjustment component is arranged between the multiple T-shaped sliding bodies located in the mounting cylinder and the mounting cylinder.

[0015] To facilitate the movement of the helmet body, a sliding rail is provided at the bottom of the hot press frame, and a wheeled mobile device is provided at the bottom of the molding base. The wheeled mobile device is movably mounted on the sliding rail, and an operating cavity is provided in the middle of the molding base for the mounting cylinder to enter.

[0016] In order to heat-press the aramid fiber and the helmet body together, the top heat-pressing structure includes a heat-pressing base and a slope clamping member. The top of the heat-pressing base is longitudinally movable with an upper concave mold body with a heating function. The slope clamping member is movable on both sides of the middle part of the heat-pressing base. A third electric cylinder is provided on both sides of the heat-pressing base. The output end of the third electric cylinder is fixedly connected to the slope clamping member.

[0017] The beneficial effects of the embodiments of the present invention are as follows:

[0018] 1. In this invention, when it is necessary to smoothly move the die-cut aramid fiber layer onto the helmet body, after the die-cutting equipment first cuts a whole piece of aramid fiber layer, due to the high die-cutting precision, the die-cut aramid fiber material will remain on the main body of the aramid fiber layer. Then, the main body of the aramid fiber layer is continued to be conveyed to the top area of ​​the mounting cylinder. When it is necessary to remove one of the aramid fiber materials, the mounting cylinder and the moving slide can be moved to the corresponding positions. Then, according to the shape of the aramid fiber material, the positions of the abutment and the corresponding adsorption clamp are adjusted. Then, the abutment and the adsorption clamp are moved simultaneously towards the aramid fiber material, so that the abutment and the adsorption clamp contact the bottom and top sides of the aramid fiber material respectively. The abutment can keep the aramid fiber material flat, so that the adsorption clamp can fully adsorb and grasp the aramid fiber material.

[0019] 2. In this invention, when the adsorption clamp moves the aramid fiber material onto the helmet body on the lower punch, the mounting cylinder moves into the operating cavity inside the forming base. After the mounting cylinder moves into the forming base, the abutment seat continues to rise. After the adsorption clamp moves the aramid fiber material to the upper side of the helmet body, the abutment seat and the adsorption clamp continue to move closer to each other, so that the abutment seat contacts the bottom side of the aramid fiber material. When the aramid fiber material is about to contact the top of the helmet body, the adsorption clamp stops adsorbing the aramid fiber material. Then, the aramid fiber material is clamped by the adsorption clamp and the abutment seat. When the aramid fiber material moves onto the helmet body, it falls precisely into the designated position on the helmet body. Attached Figure Description

[0036] like Figures 1 to 8 As shown, the present invention discloses an automatic production line for processing bulletproof helmets, including a production line frame 1. The production line frame 1 includes a die-cutting frame 2, a gripping frame 3, and a hot press frame 4. A die-cutting device 5 is provided on the die-cutting frame 2. The die-cutting device 5 is a common laser die-cutting machine in the prior art, which is a prior art device known to those skilled in the art. By driving the laser die-cutting head to move in the XY axis direction, a whole piece of aramid fiber layer is die-cut into aramid fiber material of the corresponding shape.

[0037] The hot press frame 4 is equipped with a top hot press structure, which includes a hot press base 33 and a slope clamping member 35. A heating upper concave mold 34 is longitudinally movable at the top of the hot press base 33. Slope clamping members 35 are movable on both sides of the middle of the hot press base 33. A third electric cylinder 36 is installed on both sides of the hot press base 33. The output end of the third electric cylinder 36 is fixedly connected to the slope clamping member 35. After the forming base 13 is moved to the bottom of the hot press base 33, the upper concave mold 34 and the lower convex mold 14 are positioned correspondingly, and the helmet body is placed on the lower convex mold 14. Aramid fiber material is also placed on the helmet body. The third electric cylinders 36 on both sides are then activated to move the slope clamping members 35. The movement causes the sloped clamping member 35 to contact the aramid fiber material, allowing the aramid fiber material to adhere to the helmet body. A hydraulic drive device is installed on the hot pressing base 33, which drives the upper concave mold 34 to descend. The upper concave mold 34 contacts the top of the helmet body and the aramid fiber material. The upper concave mold 34 also has a heating function, which heat-presses the helmet body and the aramid fiber material together, forming the aramid fiber material and the helmet body together. The sloped clamping member 35 is used to fix the aramid fiber material. When the upper concave mold 34 contacts the top of the helmet body, the sloped clamping member 35 can keep the unformed area between the aramid fiber material and the helmet body fixed, ensuring the forming effect of the aramid fiber material and the helmet body.

[0038] It also includes a lifting slide 6, and an XY axis moving device 7 is provided between the lifting slide 6 and the gripping frame 3. The XY axis moving device 7 is a prior art device used to drive the lifting slide 6 to move laterally and longitudinally. It is used in a variety of CNC equipment and generally uses a lead screw transmission structure to drive the lifting slide 6 to move in all directions in a planar manner. It is a prior art device known to those skilled in the art.

[0039] A lifting seat 8 is longitudinally movable at the bottom of the lifting slide 6. The lifting seat 8 is longitudinally movable on the lifting slide 6 via a lifting slide rod. The lifting slide 6 has a technical structure for driving the longitudinal movement of the lifting slide rod. Multiple adsorption clamps 9 are arranged on the outside of the lifting seat 8, with the multiple adsorption clamps 9 arranged in pairs. A sliding adjustment structure for adjusting the position of the multiple adsorption clamps 9 is provided between the lifting seat 8 and the lifting slide 6. The sliding adjustment structure includes a through slide groove 16, a triangular connector 18, and a circumferential drive structure. Multiple through slide grooves 16 are fixedly connected to the bottom circumference of the lifting seat 8. T-shaped sliding bodies 17 are slidably connected to the through slide grooves 16. Two adsorption clamps 9 are respectively set on the T-shaped sliding bodies. On both sides of the body 17, triangular connectors 18 are fixedly connected to the T-shaped sliding body 17. The triangular connectors 18 are provided with inclined grooves 19. Rotating parts 20 are slidably arranged on the inclined grooves 19. The bottom of the lifting seat 8 is provided with a circumferential drive structure for moving multiple triangular connectors 18. When it is necessary to adjust the position of multiple adsorption clamps 9 to adapt to aramid fiber materials of different shapes, the rotating parts 20 in the inclined grooves 19 are pushed to move up or down in the triangular connectors 18, so that the T-shaped sliding body 17 slidably connected in the through grooves 16 drives the two adsorption clamps 9 to move along the sliding trajectory of the through grooves 16, thereby adjusting the position of the adsorption clamps 9.

[0040] The circumferential drive structure includes a lifting ring sleeve 21 and a first electric cylinder 23. The lifting ring sleeve 21 is slidably sleeved on the bottom of the lifting seat 8. Multiple connecting rods 22 are fixedly connected to the bottom circumference of the lifting ring sleeve 21. The connecting rods 22 are rotatably connected to the rotating part 20. The first electric cylinder 23 is set on the lifting slide 6. The output end of the first electric cylinder 23 is fixedly connected to the lifting ring sleeve 21. When the first electric cylinder 23 is started, it drives the lifting ring sleeve 21 to descend, which causes the lifting ring sleeve 21 to drive the multiple connecting rods 22 to descend. The connecting rods 22 push the rotating part 20 to move on the triangular connecting part 18, thereby adjusting the position of the triangular connecting part 18, the T-shaped sliding body 17 and the adsorption clamp 9.

[0041] The bottom of the lifting slide ram 6 is fixedly connected to an annular suction cylinder 24. An suction pipe 25 connects the adsorption clamp 9 to the annular suction cylinder 24. The lifting slide ram 6 is equipped with an adsorption device 26, which is connected to the annular suction cylinder 24. When the adsorption clamp 9 needs to adsorb aramid fiber material, the adsorption device 26 is activated. Multiple adsorption clamps 9 are operated simultaneously through the annular suction cylinder 24 and multiple suction pipes 25, creating a negative pressure adsorption effect between the adsorption clamp 9 and the aramid fiber material, allowing the adsorption clamp 9 to adsorb and grasp the aramid fiber material. When the aramid fiber material needs to be discharged, the adsorption device 26 creates gas and gaps between the adsorption clamp 9 and the aramid fiber material, completing the discharge of the aramid fiber material.

[0042] A transverse sliding frame 10 is fixedly connected between the gripping frame 3 and the hot press frame 4. A mounting cylinder seat 11 is laterally movable on the transverse sliding frame 10. A sliding seat 27 is slidably connected inside the transverse sliding frame 10. A second electric cylinder 28 is mounted on the top of the sliding seat 27, and its output end is fixedly connected to the bottom end of the mounting cylinder seat 11. A transmission screw 37 is rotatably connected to the bottom of the transverse sliding frame 10. A first drive motor 38 is mounted on one side of the transverse sliding frame 10, and its output end is fixedly connected to the transmission screw 37. The sliding seat 27 and the transmission screw 37 are in a transmission engagement. When the mounting cylinder needs adjustment... When the position of the mounting cylinder 11 corresponds to the position of the lifting slide 6, the first drive motor 38 is started to drive the transmission screw 37 to rotate, so that the sliding seat 27 can adjust the position of the mounting cylinder 11. The top of the sliding seat 27 is fixedly connected to the lifting slot frame 39, and the mounting cylinder 11 is slidably connected to the lifting slot frame 39. After the mounting cylinder 11 moves to the position corresponding to the lifting slide 6, in order to bring the abutment seat 12 and the adsorption clamp 9 closer to each other, the second electric cylinder 28 is started to drive the mounting cylinder 11 to move longitudinally on the lifting slot frame 39, thereby adjusting the height of the abutment seat 12.

[0043] The top of the mounting base 11 is provided with multiple abutment seats 12, which are arranged in pairs and correspond one-to-one with the adsorption clamp 9. The mounting base 11 is provided with a position adjustment structure for adjusting the position of the multiple abutment seats 12. The position adjustment structure includes a fixed slide groove 29 and a threaded adjustment component. Multiple fixed slide grooves 29 are fixedly connected to the inner circumference of the mounting base 11. T-shaped sliding bodies 17 are also slidably arranged on the fixed slide grooves 29. Two abutment seats 12 are fixedly connected to the top two sides of the T-shaped sliding body 17 respectively. A threaded adjustment component is provided between the multiple T-shaped sliding bodies 17 located in the mounting base 11 and the mounting base 11. When it is necessary to align the position of the multiple abutment seats 12 with the longitudinal position of the adsorption clamp 9, the threaded adjustment component drives the T-shaped sliding bodies 17 to move in the fixed slide grooves 29, thereby further moving the position of the abutment seats 12.

[0044] The threaded adjustment assembly includes a threaded disc 40, a second drive motor 41, and threaded seats 42. The threaded disc 40 is rotatably connected inside the mounting cylinder 11. The second drive motor 41 is located at the bottom of the mounting cylinder 11. The output end of the second drive motor 41 is fixedly connected to the bottom of the threaded disc 40. Each T-shaped sliding body 17, which is slidably disposed in the fixed slide groove 29, has a threaded seat 42 at its bottom. The threaded seat 42 is threadedly connected to the threaded disc 40. When it is necessary to adjust the position of the abutment seat 12 to correspond with the adsorption clamp 9, the second drive motor 41 is started to drive the threaded disc 40 to rotate, so that the threaded disc 40 drives multiple threaded seats 42 to move, thereby driving the T-shaped sliding body 17 and the abutment seat 12 in the fixed slide groove 29 to move together.

[0045] The forming base 13 is movably mounted on the hot press frame 4. A lower punch 14 is provided on the top of the forming base 13. The top of the forming base 13 has multiple rectangular inlets and outlets 15 for the abutment seat 12 to extend out. The rectangular inlets and outlets 15 can adapt to the different positions of the abutment seat 12. A sliding rail 30 is provided at the bottom of the hot press frame 4. A wheel-type mobile device 31 is provided at the bottom of the forming base 13. The wheel-type mobile device 31 is movably mounted on the sliding rail 30. The wheel-type mobile device 31 is a prior art mobile device driven by electricity. The wheel-type mobile device 31 can move along the path of the sliding rail 30 to move the lower punch 14 of the forming base 13.

[0046] The molding base 13 has an operating cavity 32 in the middle for the mounting cylinder 11 to enter. After the adsorption clamp 9 adsorbs the die-cut aramid fiber material, the lifting slide 6 is moved to the top side of the molding base 13 by the XY axis moving device 7. Then, the mounting cylinder 11 is moved into the operating cavity 32 of the molding base 13 through the transmission screw 37. When the aramid fiber material needs to be placed on the helmet body, the abutment seat 12 is first extended to the top side of the molding base 13, and then the abutment seat 12 is driven to contact the bottom side of the aramid fiber material. When the aramid fiber material is about to contact the top of the helmet body, the adsorption clamp 9 stops adsorbing the aramid fiber material. Then, the aramid fiber material is clamped by the adsorption clamp 9 and the abutment seat 12. When the aramid fiber material moves onto the helmet body, the aramid fiber material falls accurately into the designated position on the helmet body.

[0047] The working principle of the automated production line for processing bulletproof helmets:

[0048] A whole piece of aramid fiber layer is conveyed on the die-cutting equipment 5. The die-cutting equipment 5 is used to perform die-cutting operation on the aramid fiber layer. Multiple parallel and different aramid fiber materials can be die-cut from the aramid fiber layer. Then, the die-cut aramid fiber layer and the multiple aramid fiber materials that remain are moved to the range of the gripping frame 3. Then, according to the forming sequence, the multiple aramid fiber materials are processed onto the helmet body in sequence. The helmet body is placed on the lower punch 14, and the forming base 13 is moved to the intersection of the hot press frame 4 and the gripping frame 3. One side of the transverse sliding slot frame 10 extends into the operating cavity 32.

[0049] At this time, adjust the positions of the mounting cylinder 11 and the lifting slide 6 respectively, and move the mounting cylinder 11 and the lifting slide 6 to the corresponding positions between the aramid fiber materials. Then, according to the shape of the aramid fiber material, adjust the positions of the abutment seat 12 and the adsorption clamp 9 accordingly. Then, move the abutment seat 12 and the adsorption clamp 9 simultaneously towards the aramid fiber material, so that the abutment seat 12 and the adsorption clamp 9 contact the bottom and top sides of the aramid fiber material respectively. The abutment seat 12 can keep the aramid fiber material flat, so that the adsorption clamp 9 can fully adsorb and grab the aramid fiber material. After the adsorption clamp 9 grabs the aramid fiber material, it drives the lifting slide 6 and the aramid fiber material to the upper side of the helmet body. At this time, the mounting cylinder 11 is also moved into the operating cavity 32.

[0050] The abutment seat 12 extends to the top side of the molding base 13, and then the abutment seat 12 is brought into contact with the bottom side of the aramid fiber material. When the aramid fiber material is about to contact the top of the helmet body, the adsorption clamp 9 stops adsorbing the aramid fiber material. Then, the aramid fiber material is clamped by the adsorption clamp 9 and the abutment seat 12. When the aramid fiber material moves onto the helmet body, the aramid fiber material falls precisely into the designated position on the helmet body. After the aramid fiber material is placed on the helmet body, the molding base 13, the helmet body and the aramid fiber material are moved to the bottom of the hot pressing base 33, and the upper concave mold 34 is driven down. The upper concave mold 34 contacts the top of the helmet body and the aramid fiber material. The upper concave mold 34 also has a heating function, which heats and presses the helmet body and the aramid fiber material together, so that the aramid fiber material and the helmet body are formed together.

[0051] Using the above method, multiple aramid fiber materials are sequentially molded onto the helmet body.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
