Description

Technical Field

[0001] The invention relates to the technical field of bulk machines, in particular to high-precision fluoroplastic plate welding automation equipment. Background Art

[0002] Fluoroplastic is a special polymer material containing fluorine atoms in its molecular structure. Due to its excellent chemical stability, heat resistance, insulation and other properties, fluoroplastic sheets have excellent corrosion resistance, high temperature resistance and electrical insulation, and are widely used in chemical, construction, electronic and electrical, medical and other fields.

[0003] Fluoroplastic sheets come in many different types depending on the material, including PTFE, FEP, PFA, PTFE, etc. During the processing of fluoroplastic sheets for parts, the fluoroplastic sheets need to be welded to connect them with other workpieces. During welding, the surface of the fluoroplastic sheet needs to be heated to melt it for welding. Polytetrafluoroethylene (PTFE) in fluoroplastic sheets is difficult to melt and needs to be heated by hot pressing with a hot press plate, while PFA and FEP can be heated by hot air heating. The existing welding equipment has a single heating method, mainly using a hot press plate for heating, which is difficult to meet the heating requirements of different fluoroplastic sheets. In addition, some fluoroplastic sheet workpieces have complex shapes and are uneven, and it is difficult for a flat heating plate to effectively heat the welding surface to melt it. Summary of the Invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-precision fluoroplastic sheet welding automation equipment, including a welding machine, a translation mechanism, a switching mechanism and a heating component, wherein: The front end of the welding machine is provided with a welding chamber, the welding chamber is provided with a heating chamber, and the upper and lower sides of the welding chamber are equipped with a lower lifting welding platform and an upper lifting welding platform that cooperate with each other.

[0010] The small hot air gun is started, and the first servo cylinder drives the lower lifting welding platform and the upper lifting welding platform to move to both sides of the hot plate rack, so that the fixed fluoroplastic plate is aligned with the surface of the air jet seat. At this time, the air jet holes on the air jet seat spray hot air to heat the surface of the fixed fluoroplastic.

[0014] The second servo cylinder drives the lifting seat to move up and down, thereby driving the hot air rack and the hot plate rack connected to the lifting seat to move up and down, so that the hot plate rack or the hot air rack to be used is lifted and lowered to be aligned with the translation mechanism.

[0015] The translation mechanism is arranged on both sides of the middle of the welding chamber and the heating chamber, and is used to drive the hot plate heating mechanism and the hot air heating mechanism to translate to the welding chamber.

[0016] Preferably, the translation mechanism includes guide rails symmetrically installed on both sides of the inner wall of the welding chamber, the guide rails extend into the heating chamber, the outer side of the guide rails is slidably connected to an electric slide, the outer end of the electric slide is installed with a movable seat, and a clamping cylinder facing the middle of the welding machine is installed in the movable seat, and the clamping cylinder cooperates with the hot air rack and the hot plate rack.

[0017] A clamping seat plate is installed at the output end of the clamping cylinder, and holes are provided on the surface of the clamping seat plate.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] See also Figures 1-13 The embodiment of the present invention provides a technical solution: a high-precision fluoroplastic sheet welding automation equipment, including a welding machine 1, a translation mechanism 4, a switching mechanism 5 and a heating component 6, wherein: The front end of the welding machine 1 is provided with a welding chamber 12, a heating chamber 13 is provided in the welding chamber 12, and a lower lifting welding platform 2 and an upper lifting welding platform 3 are installed on the upper and lower sides of the welding chamber 12. Furthermore, the upper lifting welding table 3 and the lower lifting welding table 2 both include a lifting table body 22 movably connected to the welding chamber 12, and the first servo cylinder 21 is symmetrically installed on the upper and lower sides of the front end of the welding machine 1. The output rod of the first servo cylinder 21 extends into the welding chamber 12 and is fixedly connected to the lifting table body 22. The sides of the lifting table bodies 22 that are close to each other are symmetrically installed with fixed seat plates 23, and the fixed seat plate 23 is installed with a fixed cylinder 24, and the output end of the fixed cylinder 24 is installed with a fixed push plate 25.

[0029] Specifically, the fluoroplastic plate workpieces to be welded are placed on the lifting platform bodies 22 of the lower lifting welding platform 2 and the upper lifting welding platform 3 respectively, and the fixing cylinder 24 is started to drive the fixing push plate 25 to clamp and fix the fluoroplastic plate.

[0030] Furthermore, the heating assembly 6 includes a hot plate heating mechanism 61 and a hot air heating mechanism 62 vertically distributed in the heating chamber 13; In one embodiment, the fluoroplastic plate is heated by a hot plate heating method. The hot plate heating mechanism 61 includes a hot plate frame 611, an isolation plate 614 is installed in the middle of the hot plate frame 611, and heating plates 612 and multiple heating frame plates 613 are symmetrically installed on the upper and lower sides of the isolation plate 614. Electric heating structures are installed inside the heating plates 612 and the heating frame plates 613. The heating frame plates 613 are hollow frame-shaped and are fixed layer by layer on the outside of the heating frame plates 613. The heating frame plates 613 and the central heating plate 612 are combined into a rectangular heating surface, and the multiple heating frame plates 613 and the heating plates 612 can be independently controlled and started.

[0031] Specifically, when the heating plate 612 and the heating frame plate 613 start heating, the first servo cylinder 21 drives the lower lifting welding platform 2 and the upper lifting welding platform 3 to move to both sides of the hot plate frame 611, so that the fixed fluoroplastic plate contacts the heating plate 612 and the heating frame plate 613, and starts hot pressing.

[0032] In this embodiment, the hot plate heating is mainly used to heat the flat polytetrafluoroethylene (PTFE) fluoroplastic plate to melt the welding surface thereof.

[0033] During the heating process, the fluoroplastic plate, the heating plate 612 and the heating frame plate 613 are all tightly fitted to the surface of the fluoroplastic plate. During the heating process, the first servo cylinder 21 can continue to start to increase the pressure between the fluoroplastic plate and the heating plate 612, so that the heating and hot melting effect is better.

[0034] It should be noted that when processing a frame-shaped fluoroplastic plate, only a single or multiple heating frame plates 613 corresponding to the size of the fluoroplastic plate can be started to heat the fluoroplastic plate to save electricity.

[0035] In another embodiment, the hot air heating mechanism 62 includes a hot air rack 623, a distribution pipe 626 is symmetrically installed in the middle of the hot air rack 623, and a plurality of integrated pipes 625 are symmetrically installed and connected on the upper and lower sides of the distribution pipe 626. A small hot air gun 624 facing vertically outward is installed on the outside of the integrated pipe 625. The air outlet end of the small hot air gun 624 is equipped with a rectangular jet seat 627, and the jet seat 627 is provided with a plurality of jet holes 628. The jet seats 627 are closely arranged to form a rectangular surface, and the multiple small hot air guns 624 arranged on the upper and lower sides of the hot air rack 623 can be independently controlled and started.

[0036] Specifically, the small hot air gun 624 is started, and the first servo cylinder 21 drives the lower lifting welding platform 2 and the upper lifting welding platform 3 to move to both sides of the hot plate rack 611, so that the fixed fluoroplastic plate is aligned with the surface of the jet seat 627. At this time, the jet hole 628 on the jet seat 627 sprays hot air to heat the surface of the fixed fluoroplastic.

[0037] In this embodiment, hot air heating is mainly used for heating PFA, FEP materials and fluoroplastic plates with complex shapes.

[0038] During the heating process, the fluoroplastic plate does not need to be in close contact with the air jet seat 627. During the heating process, the hot air ejected from the air jet seat 627 can evenly heat the fluoroplastic plate. Even if the fluoroplastic plate has a complex and uneven shape, the hot air can heat and melt it.

[0039] It should be noted that, according to the shape of the fluoroplastic plate and the heating requirements, only some of the small hot air guns 624 may be activated to perform regional heating to save energy.

[0040] Furthermore, the welding machine 1 is also equipped with an air supply device 14, which is specifically an air pump. A socket 15 is installed at the rear end of the welding chamber 12. A first wire pipe 64 and an air intake pipe 63 are installed between the socket 15 and the hot air rack 623. The air intake pipe 63 is connected to the air supply device 14, and the air intake pipe 63 is fixedly connected to the distribution pipe 626. A second wire pipe 65 is installed between the socket 15 and the hot plate rack 611. The first wire pipe 64, the second wire pipe 65 and the air intake pipe 63 are all retractable hoses.

[0041] Specifically, the heating plate 612 and the heating frame are connected to electricity through the first wire tube 64, and the small hot air gun 624 is ventilated and connected to the air inlet pipe 63 through the second wire tube 65. When the hot air heating mechanism 62 or the hot plate heating mechanism 61 is extended, the retractable hose can maintain normal air supply and power supply.

[0042] Furthermore, the switching mechanism 5 is provided with two groups, which are respectively arranged on the upper and lower sides of the heating chamber 13, and are respectively connected to the hot plate heating mechanism 61 and the hot air heating mechanism 62. The switching mechanism 5 includes a fixed table 52 installed in the heating chamber 13, and a second servo cylinder 51 is installed on the outside of the fixed table 52. The output rod of the second servo cylinder 51 extends to the inside of the fixed table 52 and is fixed with a lifting seat 53. The inside of the lifting seat 53 is symmetrically installed with a slide rail 54 facing the welding chamber 12. The hot air rack 623 and the hot plate rack 611 are symmetrically installed with a connecting slide 66. The slide rail 54 is slidably connected to the connecting slide 66. The lifting seat 53 in the symmetrically arranged switching mechanism 5 is slidably connected to the hot air rack 623 and the hot plate rack 611 through the slide rail 54.

[0043] Specifically, the second servo cylinder 51 drives the lifting seat 53 to move up and down, and then drives the hot air rack 623 and the hot plate rack 611 connected to the lifting to move up and down, so that the hot plate rack 611 or the hot air rack 623 to be used is lifted and lowered to be aligned with the translation mechanism 4.

[0044] Furthermore, the translation mechanism 4 is arranged on both sides of the middle of the welding chamber 12 and the heating chamber 13, and is used to drive the hot plate heating mechanism 61 and the hot air heating mechanism 62 to translate to the welding chamber 12. The translation mechanism 4 includes guide rails 41 symmetrically installed on both sides of the inner wall of the welding chamber 12. The guide rails 41 extend into the heating chamber 13. The outer side of the guide rails 41 is slidably connected to an electric slide 42. The outer end of the electric slide 42 is installed with a movable seat 43. The movable seat 43 is installed with a guide rail 41 that moves toward the center of the welding machine 1. The clamping cylinder 44 of the part cooperates with the hot air rack 623 and the hot plate rack 611. The output end of the clamping cylinder 44 is installed with a clamping seat plate 45, and holes are provided on the surface of the clamping seat plate 45. Connecting seats 621 are symmetrically installed on both sides of the hot air rack 623 and the hot plate rack 611. The surface of the connecting seat 621 is provided with a clamping groove 622 that fits with the clamping seat plate 45, and the inner bottom surface of the clamping groove 622 is installed with a cylindrical pin that fits with the empty hole on the clamping seat plate 45.

[0045] Specifically, after the hot plate rack 611 or hot air rack 623 to be used by the switching mechanism 5 moves to be aligned with the clamping seat plate 45 on the switching mechanism 5, the clamping cylinder 44 is started, and the clamping cylinder 44 drives the clamping seat plate 45 to clamp toward the middle, so that the clamping seat plate 45 enters the clamping groove 622 in the connecting seat 621 on both sides of the hot plate rack 611 or the hot air rack 623. At this time, the electric slide 42 drives the clamped hot air rack 623 or hot plate rack 611 to move between the lower lifting welding platform 2 and the upper lifting welding platform 3. At this time, the first servo cylinder 21 is started first to drive the two lower lifting welding platforms 2 and the upper lifting welding platform 3 to contact the heating mechanism to heat the fluoroplastic plate. After the heating is completed, the lower lifting welding platform 2 is separated from the upper lifting welding platform 3, and the electric slide 42 moves the heating mechanism back to the heating chamber 13. At this time, the lower lifting welding platform 2 and the upper lifting welding platform 3 are merged again so that the heated fluoroplastic plates are merged and connected to complete the welding.

[0046] Furthermore, a controller 11 is installed on the side end of the welding machine 1. The controller 11 is a touch screen controller 11. The first servo cylinder 21, the second servo cylinder 51, the fixed cylinder 24, the clamping cylinder 44, the heating plate 612, the heating frame plate 613 and the small hot air gun 624 are all polarity-connected to the controller 11 and started by the controller 11. The controller 11 is a PLC programmable controller 11.

[0047] The present invention provides a high-precision fluoroplastic plate welding automation equipment driving structure usage and function: first, the fluoroplastic plate workpiece to be welded is placed on the lifting platform body 22 of the lower lifting welding platform 2 and the upper lifting welding platform 3 respectively, and the fixed cylinder 24 is started to make the fixed cylinder 24 drive the fixed push plate 25 to clamp and fix the fluoroplastic plate.

[0048] According to the material of the fluoroplastic plate to be welded, the hot air heating mechanism 62 or the hot plate heating mechanism 61 is selected through the switching mechanism 5, and the second servo cylinder 51 is started by the controller 11. The second servo cylinder 51 drives the lifting seat 53 to move up and down. The lifting seats 53 on the upper and lower sides respectively drive the hot air heating mechanism 62 and the hot plate heating mechanism 61 to move up and down. The mechanism to be used, the hot air heating mechanism 62 or the hot plate heating mechanism 61, is moved to the middle of the heating chamber 13 by the control of the second servo cylinder 51 so that it is aligned with the clamping seat plate 45 on the translation mechanism 4. At this time, the movable seat 43 in the translation mechanism 4 is moved to the heating chamber 13 through the electric slide 42, and is aligned with the connecting seat 621 on the hot air heating mechanism 62 or the hot plate heating mechanism 61 in the middle, and then the clamping cylinder 44 is started, and the clamping cylinder 44 drives the clamping seat plate 45 to be inserted into the clamping groove 622 in the connecting seat 621, and then the movable seat 43 drives the clamped hot air heating mechanism 62 or the hot plate heating mechanism 61 to move forward to the welding chamber 12 through the electric slide 42, and is aligned with the hot air heating mechanism 62 or the hot plate heating mechanism 61 fixed at the bottom. The lifting welding table 2 is aligned with the fluoroplastic plate on the upper lifting welding table 3, and then the first servo cylinder 21 is started to drive the two lower lifting welding tables 2 and the upper lifting welding table 3 to contact the heating mechanism to heat the fluoroplastic plate. After the heating is completed, the lower lifting welding table 2 is separated from the upper lifting welding table 3, and the electric slide 42 moves the heating mechanism back to the heating chamber 13. At this time, the first servo cylinder 21 is controlled to make the lower lifting welding table 2 rise and the upper lifting welding table 3 fall. The heated fluoroplastic plates are merged and connected to complete the welding.
