The plasma spraying technology uses a plasma arc driven by direct current as a heat source to heat materials such as ceramics, alloys, and metals to a molten or semi-molten state, and sprays them onto the surface of a pre-treated workpiece at a high speed to form a firmly attached surface layer. At present, plasma spraying treatment is also carried out during the production of glass. Referring to the Chinese patent "A Plasma Spraying Fixture and Equipment" with the publication number "CN117187733A", this patent points out that when the existing equipment performs spraying and clamping, it is easy to cause the problem of clamping looseness due to the small clamping surface, which has a certain impact on subsequent spraying; however, this method still has problems that the clamping method is likely to affect the spraying effect and spraying range of the equipment.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-8 , the present invention provides two technical solutions, specifically including the following embodiments:

[0034] Embodiment 1: In the embodiment of the present invention, a plasma spraying device for glass production includes a machine body 1. A robotic arm 4 is installed inside the machine body 1, and a spraying module 5 is connected to the end of the robotic arm 4 for spraying an object body 7 placed inside the machine body 1. The robotic arm 4 is an existing device for driving the spraying module 5 to operate to achieve uniform spraying, and the control is realized based on an existing PLC control module;

[0035] Specifically, the spraying module 5 is an existing plasma spraying device, which will not be elaborated here;

[0036] Furthermore, a carrier plate 6 is slidably connected up and down inside the machine body 1. The object body 7 is placed above the carrier plate 6. Locking components are provided on both sides of the object body 7 for clamping both sides of the object body 7 during the spraying process. When spraying the object body 7, first place it above the carrier plate 6, and then complete the clamping operation of the object body 7 through the locking components on both sides;

[0037] Furthermore, the locking component includes a side positioning frame 10. The side positioning frame 10 is slidably installed inside the machine body 1. A plurality of outer sleeves 1002 are rotatably connected to the side of the side positioning frame 10 close to the object body 7, and positioning clamping plates 1003 are fixed on the outer sides of the outer sleeves 1002. Support springs 1004 are fixed between the positioning clamping plates 1003 and the side positioning frame 10. A transmission component is provided on the top surface of the side positioning frame 10 for driving the plurality of positioning clamping plates 1003 to be separated from the surface of the object body 7 in sequence during the spraying process of the object body 7;

[0038] Specifically, during the clamping process, as the side positioning frame 10 moves towards the object body 7, the positioning clamping plate 1003 can first come into contact with the side of the object body 7. At this time, through the support of the plurality of support springs 1004, the positioning operation of the object body 7 can be completed through the positioning clamping plate 1003;

[0039] Specifically, when spraying the side of the object body 7, as the transmission component operates, it can drive the plurality of positioning clamping plates 1003 to be separated from the side of the object body 7 in sequence, thereby completing the spraying operation on the side of the object body 7, improving the spraying range and spraying effect, and at the same time not affecting the clamping effect on the object body 7;

[0040] Specifically, the transmission assembly includes a driving rod 11, which is rotatably connected to the top of the side positioning frame 10, and a plurality of positioning sleeves 12 are fixedly sleeved on the outside of the driving rod 11, and a transmission push plate 1201 is fixedly installed on the outside of the positioning sleeves 12, and the plurality of transmission push plates 1201 are staggeredly installed, and the deflection angles of two adjacent transmission push plates 1201 are the same, and are used to sequentially move the positioning clamping plate 1003 as the driving rod 11 runs;

[0041] Specifically, refer to Figure 4 , Figure 6 When the driving rod 11 rotates, it can drive multiple positioning sleeves 12 and multiple transmission push plates 1201 to rotate simultaneously. At this time, as the offset angles of the transmission push plates 1201 are different, they can contact the positioning clamping plates 1003 in sequence, so that the positioning clamping plates 1003 can be rotated along the outer sleeve 1002 under force, and the supporting springs 1004 are squeezed until the transmission push plates 1201 pass over the positioning clamping plates 1003. Then, the positioning clamping plates 1003 are reset by the supporting springs 1004 and contact the side of the workpiece body 7 again;

[0042] Furthermore, a plurality of support springs 1004 are each provided with a telescopic sleeve 1005, and a vent hole 1006 is provided at the end of the telescopic sleeve 1005, and both ends of the telescopic sleeve 1005 are rotatably connected to the positioning clamping plate 1003 and the side positioning frame 10, respectively, so as to extend the reset time of the positioning clamping plate 1003 and reduce the impact force between the positioning clamping plate 1003 and the workpiece body 7 when the positioning clamping plate 1003 is reset;

[0043] Specifically, through the arrangement of the telescopic sleeve 1005, when the positioning splint 1003 is pressed and rotates along the outer sleeve 1002 to squeeze the support spring 1004, the telescopic sleeve 1005 can be forced to retract, and the air inside it can be discharged through the vent hole 1006. When the positioning splint 1003 is reset by the support spring 1004, the gas can re-enter the interior of the telescopic sleeve 1005 through the vent hole 1006. On the one hand, the time required for the positioning splint 1003 to reset is extended to ensure the spraying effect. At the same time, it can avoid excessive impact force between the positioning splint 1003 and the workpiece body 7 when resetting, effectively ensuring the spraying quality of the workpiece body 7.

[0044] Specifically, the transmission assembly also includes a driving motor 13, which is fixedly mounted on the top surface of the side positioning frame 10, and the output end of the driving motor 13 and the end of the driving rod 11 are both fixedly sleeved with sprockets, and a transmission chain 14 is connected through the sprocket, and the transmission chain 14 and the sprocket are adapted to each other to realize the transmission operation, so that the driving rod 11 can realize the driving operation through the driving motor 13;

[0045] Specifically, fixing brackets 1101 are fixedly installed on both sides of the side positioning bracket 10, and both ends of the driving rod 11 are respectively rotatably connected inside the two fixing brackets 1101;

[0046] Specifically, a sliding rod 1001 is fixedly installed on the side of the side positioning bracket 10 away from the workpiece body 7. The sliding rod 1001 is slidably connected to the machine body 1. A protective cover 3 is fixedly installed on the outside of the machine body 1, and a driving cylinder body 301 is fixedly installed inside the protective cover 3. The piston end of the driving cylinder body 301 is fixedly connected to the side positioning bracket 10 for driving the side positioning bracket 10 to operate. The driving cylinder body 301 is an existing device for driving the side positioning bracket 10 to operate and complete the clamping operation;

[0047] Specifically, a sealing door 2 is rotatably connected to the side of the machine body 1, and a control panel 101 is fixedly installed on the outside of the machine body 1. The control panel 101 is based on an existing PLC control module;

[0048] Specifically, a jacking cylinder body 8 is fixedly installed inside the machine body 1. The piston end of the jacking cylinder body 8 is connected to the bearing plate 6 for driving the bearing plate 6 to slide up and down inside the machine body 1. A plurality of conical support members 9 are fixedly installed in the middle of the top surface of the bearing plate 6. By being able to slide up and down, the bearing plate 6 can slide down after the workpiece body 7 is clamped and separate from the workpiece body 7 to avoid affecting the spraying effect and the flipping operation of the workpiece body 7;

[0049] Clamping and flipping assemblies are provided at the bottoms of the side positioning brackets 10 on both sides for clamping the workpiece body 7 and driving the workpiece body 7 to perform a flipping operation. The clamping and flipping assembly includes a right-angle positioning bracket 15. The right-angle positioning bracket 15 is fixedly installed at the bottom of the side positioning bracket 10. An end shaft sleeve 16 is rotatably installed at the end of the right-angle positioning bracket 15, and a flipping clamping plate 1601 is fixedly installed at the end of the end shaft sleeve 16. The flipping clamping plate 1601 is used for clamping the workpiece body 7. A transmission belt 1503 is provided between the end shaft sleeve 16 and the driving rod 11 for driving the end shaft sleeve 16 to rotate, so as to realize the flipping of the clamped workpiece body 7;

[0050] Specifically, a plurality of anti-slip grooves 1602 are formed on the side of the flipping clamping plate 1601 close to the workpiece body 7 to ensure the clamping effect on the workpiece body 7 and avoid the phenomenon of the workpiece body 7 falling off during the flipping process;

[0051] A fixing plate 1501 is fixedly installed on the outside of the right-angle positioning bracket 15. A rotating shaft sleeve 1502 is rotatably sleeved on the outside of the fixing plate 1501. Conical transmission gears 17 are fixedly sleeved on the outside of the rotating shaft sleeve 1502 and the outside of the end shaft sleeve 16, and the two conical transmission gears 17 are meshed with each other. The transmission belt 1503 is rotatably connected between the driving rod 11 and the rotating shaft sleeve 1502;

[0052] Specifically, when the workpiece body 7 needs to be flipped after one-sided spraying, first, the support of the workpiece body 7 is completed by the upward movement of the bearing plate 6. The side positioning frames 10 move to both sides to cancel the clamping of the workpiece body 7. Then, the bearing plate 6 drives the workpiece body 7 to move down to the flipping station, that is, to make the workpiece body 7 flush with the flipping clamping plate 1601. At this time, the movement of the side positioning frame 10 can drive the flipping clamping plate 1601 to contact the workpiece body 7 to complete the clamping. After the clamping is completed, the bearing plate 6 moves down to separate from the workpiece body 7. Then, by operating the driving rod 11, through the cooperation of the transmission belt 1503 and the conical transmission gear 17, the rotating shaft sleeve 1502 and the end shaft sleeve 16 can be driven to rotate, so that the flipping clamping plate 1601 can rotate with the end shaft sleeve 16 to realize the flipping of the clamped workpiece body 7.

[0053] Embodiment 2: Based on Embodiment 1, a plasma spraying method for glass production, based on the above spraying equipment, specifically includes the following steps:

[0054] S1. Place the workpiece body 7 to be sprayed above the bearing plate 6, and support it by a plurality of conical support members 9. Then, slide the side positioning frames 10 on both sides towards the workpiece body 7 until the plurality of positioning clamping plates 1003 contact the workpiece body 7 to complete the clamping operation of the workpiece body 7. Then, drive the spraying module 5 to move through the robotic arm 4, and sequentially perform spraying operations on the outer surface of the workpiece body 7.

[0055] S2. When spraying the side of the workpiece body 7 being clamped, through the operation of the transmission component, the plurality of transmission push plates 1201 can rotate and sequentially contact the positioning clamping plates 1003, so that the positioning clamping plates 1003 are pressed to rotate along the outer shaft sleeve 1002 in sequence, and the support spring 1004 is squeezed. At this time, the spraying module 5 driven by the robotic arm 4 can spray along the positioning clamping plates 1003 that are sequentially separated from the side of the workpiece body 7 until the spraying operation is completed.

[0056] At the same time, the content not detailed in this specification belongs to the prior art well-known to those skilled in the art.

[0057] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the present invention.
