Description

Technical Field

[0001] This invention relates to the technical field of steam oven processing equipment, specifically a processing device for pre-bonding glass on the door panel of a steam oven. Background Technology

[0002] Currently, food processing methods worldwide are limited to a few basic types: frying, stir-frying, deep-frying, steaming, boiling, stewing, and baking. Among these, steaming and baking account for a significant proportion, demonstrating people's preference for these two methods. Some food processing requires both steaming and baking; some require steaming first and then baking, while others require baking first and then steaming. Therefore, a steam oven is necessary.

[0003] A steam oven is a cooking machine that contains food in a sealed space and heats it for cooking. A glass panel is fixedly installed in the center of the steam oven door so that the user can clearly see the food inside. This glass needs to be covered with a film.

[0004] Evaporation coating, often called vacuum coating, is characterized by the evaporation of materials under vacuum conditions and their condensation on the glass surface to form a film. After high-temperature heat treatment, a film layer with strong adhesion is formed on the glass surface.

[0005] During thin-film vapor deposition, the processing chamber must be kept under vacuum. However, when the operator changes parts, outside air fills the chamber, causing internal vaporized molecules to escape. This results in a heavy workload for the vacuum pump during subsequent processing, requiring reheating and evaporation to replenish the vaporized gas. The process is complex, time-consuming, labor-intensive, and inconvenient. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a processing device for pre-bonding glass on the door panel of a steam oven, thus solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a processing device for pre-gluing glass on the door panel of a steam oven, comprising a worktable, a door frame placed in the center of the worktable, a top cover above the door frame, a slide rail on the top of the inner wall of the top cover, an annular tube on the top of the inner wall of the top cover and inside the slide rail, an air outlet at the bottom of the annular tube, an air inlet extending to the outside of the top cover, a sealing glue container on the top of the inner wall of the top cover and inside the annular tube, an electric push rod slidably fitted inside the slide rail, a rubber block vertically connected to the lower end of the electric push rod, and a flexible hose connecting the rubber block and the sealing glue container.

The end of the slide rod slides in conjunction with the slide groove and can be inserted into the left end of the slide groove. An air pump is connected to the right side of the top cover and is connected to the right end of the air cushion. When the air cushion is inflated, it pushes the slide rod to the leftmost end. At this time, the slide rod is inserted into the left end of the slide groove, and a sealed space is formed between the air cushion and the top cover.

[0009] A baking module is also fixedly installed on the top of the inner wall of the top cover.

The lower end of the thin spring is connected to the lever. A microcontroller is embedded in the top cover, and an indicator light is provided on the outside of the top cover. The indicator light, the microcontroller, and the push switch are electrically connected.

[0011] The left end of the slide groove is provided with a rubber protrusion, which clamps the air cushion. When the air cushion is inflated, it pushes the slide rod to the left end of the slide groove. The slide rod touches the lever, which squeezes the press switch and the thin spring. The press switch closes and the indicator light illuminates.

[0012] Preferably, the top of the top cover is provided with a positioning ring, and cylinders are symmetrically provided on the left and right sides of the top of the top cover.

A motor is connected to the top of cylinder 1. A rope is connected to the motor drive shaft. The rope is connected to clamping block 2.

[0013] Preferably, the door frame has an extension edge connected to its inner side, and glass is provided inside the door frame. The glass rests on the extension edge, and bolts are threadedly connected to the corners of the glass, with the bolts threadedly connected to the extension edge.

[0014] Preferably, the upper end of the electric push rod is connected to a drive wheel, the drive wheel contacts the inner wall of the slide rail, the rubber block has an adhesive outlet hole on the side facing the door frame, the rubber block has an abutting part on the side facing the door frame, the abutting part abuts against the inner wall of the door frame, and the hose is connected to the adhesive outlet hole.

[0016] This invention provides a processing device for pre-bonding glass on the door panel of a steam oven. It has the following beneficial effects:

[0017] 1. This processing device for pre-coating glass on the door panel of a steam oven involves placing a top cover over the door frame and aligning a ring tube with the glass inside the frame for film coating. Using an electric actuator, rubber blocks, and sealing tubing, a sealing ring is applied after the glass is coated to strengthen the door frame, glass, and the film layer on the glass surface, further improving the sealing effect. An air pump, air cushion, and sliding rod work together to shield and seal the equipment inside the top cover, preventing the loss of internal evaporation molecules. This simplifies the complex operation of traditional processes. Attached Figure Description

[0029] This invention provides a processing device for pre-bonding glass on the door panel of a steam oven, such as... Figure 1-10 As shown, a workbench 1 has a door frame 2 placed in its center. A top cover 3 is positioned above the door frame 2. A slide rail 31 is welded to the top of the inner wall of the top cover 3. An annular pipe 4 is fixedly installed on the top of the inner wall of the top cover 3, inside the slide rail 31. An air outlet 41 is located at the bottom of the annular pipe 4, and the air inlet of the annular pipe 4 extends to the outside of the top cover 3. Before operation, see attached... Figure 1 As shown, the top cover 3 is first placed on the door frame 2, and then the raw materials used for pre-coating are evaporated into gas and sent into the annular pipe 4.

[0030] A sealing glue container 7 is fixedly installed on the top of the inner wall of the top cover 3, located inside the annular tube 4. An electric actuator 5 is slidably fitted inside the slide rail 31. A rubber block 6 is fixedly installed vertically downward at the lower end of the electric actuator 5. A flexible hose 62 connects the rubber block 6 and the sealing glue container 7. (See attached...) Figure 2 It can be seen that the slide rail 31 is a rectangular frame, and the electric push rod 5 moves one circle along the slide rail 31, which is equivalent to moving one circle along the inner side of the door frame 2.

[0031] A slide groove 32 is provided on the inner wall of the top cover 3 and below the slide rail 31. The slide groove 32 runs around the inner wall of the top cover 3, as shown in the attached figure. Figure 2 As shown. An air cushion 8 is fixedly installed inside the right end of the slide groove 32. A slide rod 9 is fixedly installed on the left side of the air cushion 8. The end of the slide rod 9 slides and engages with the slide groove 32. The slide rod 9 can be embedded into the left end of the slide groove 32. An air pump 10 is fixedly installed on the right side of the top cover 3. The inflation end of the air pump 10 is connected to the right end of the air cushion 8.

[0032] During the expansion and deployment of the air cushion 8, the front and rear edges of the air cushion 8 are always located within the groove 32.

[0033] During operation, to prevent vapor leakage of the coating material after lamination is completed, the air pump 10 is operated to inflate the air cushion 8. The inflated air cushion 8 pushes the slide rod 9 to the left. When the slide rod 9 reaches the leftmost end, it engages with the left end of the slide groove 32, and the air cushion 8 covers the annular tube 4, creating a sealed space between the air cushion 8 and the top cover 3, thus sealing the vapor. When the top cover 3 is raised, vapor leakage can be prevented.

[0034] A baking module is also fixedly installed on the top of the inner wall of the top cover 3. The baking module consists of heating wires, baking lamps, etc., and is a conventional technical method. After the coating material evaporates, it encounters the cold glass and condenses into a film on the glass surface. Then, the baking module performs high-temperature heat treatment, resulting in a film layer with strong adhesion on the glass surface. Since the baking module is existing technology, its specific structure and connection method will not be described.

[0035] A groove 33 is provided at the upper left end of the slide 32. A lever 37 is pivotally connected in the groove 33. The movable end of the lever 37 can contact the slide rod 9. A push switch 38 is fixedly installed on the top of the inner wall of the groove 33. A thin spring 39 is welded to the top of the inner wall of the groove 33. The lower end of the thin spring 39 is welded to the lever 37. A microcontroller 34 is embedded in the top cover 3. An indicator light 35 is fixedly installed on the outside of the top cover 3. The indicator light 35, the microcontroller 34, and the push switch 38 are electrically connected.

[0036] Combined with appendix Figure 9 A rubber protrusion 36 is fixedly bonded to the left end of the slide groove 32, and the rubber protrusion 36 plays a clamping role for the air cushion 8.

[0037] The air cushion 8 inflates and pushes the slide rod 9 to the left end of the slide groove 32. The slide rod 9 contacts the lever 37, which squeezes the press switch 38 and the thin spring 39. The press switch 38 closes, illuminating the indicator light 35. The indicator light 35 illuminates, indicating that the top cover 3 is sealed and can be removed from the door frame 2. When the slide rod 9 is inserted into the left end of the slide groove 32, the rubber protrusion 36 clamps the air cushion 8. The rubber protrusion 36 acts as an obstruction, preventing the slide rod 9 from automatically detaching from the left end of the slide groove 32.

[0038] A positioning ring 11 is welded to the top of the top cover 3. Cylinder 12 is symmetrically fixedly installed on the left and right sides of the top of the top cover 3. The movable end of cylinder 12 passes through the positioning ring 11 and is welded to a clamping block 13. Slide rod 2 14 is symmetrically provided on the front and rear sides of the top of the top cover 3. One end of slide rod 2 14 is welded to the fixed end of cylinder 1.

[0039] The slide rod 14 is fitted with a large spring 16, and the slide rod 14 is slidably fitted with a clamping block 15. The large spring 16 is welded to the clamping block 15. A motor 17 is fixedly mounted on the top of the cylinder 12. The drive shaft of the motor 17 is fixedly bound with a rope 18, and the rope 18 is fixedly bound to the clamping block 15.

[0040] The lower ends of clamping blocks 13 and 15 can abut against the door frame 2. By retracting cylinder 12, motor 17 winds rope 18, causing clamping blocks 13 and 15 to move closer to the door frame 2. When clamping blocks 13 and 15 abut against the door frame 2, they also abut against the outer side of the top cover 3. Thus, the clamping blocks effectively fix the door frame 2 and the top cover 3 together. This allows the rubber block 6 at the lower end of the electric actuator 5 to align with the inner side of the door frame 2.

[0041] An extension edge 21 is welded to the inside of the door frame 2. A glass 22 is provided inside the door frame 2. The glass 22 is placed on the extension edge 21. A bolt 23 is threadedly connected to the corner of the glass 22. The bolt 23 is threadedly connected to the extension edge 21.

[0042] First, use bolts 23 to fix the glass 22 inside the door frame 2. Then fix the top cover 3 to the door frame 2 and apply a film coating. After the film coating is completed, the electric push rod 5 extends so that the bottom of the rubber block 6 contacts the glass 22 and the side of the rubber block 6 abuts against the inside of the door frame 2.

[0043] A drive wheel 51 is fixedly mounted on the upper end of the electric actuator 5. The drive wheel 51 contacts the inner wall of the slide rail 31. A control module and a power supply are also fixedly mounted inside the electric actuator 5. The control module controls the drive wheel 51 to rotate, allowing the electric actuator 5 to move along the slide rail 31.

[0044] The rubber block 6 has an adhesive outlet 61 on the side facing the door frame 2, and an abutment part 63 on the same side. The rubber block 6 and the abutment part 63 are integrally formed. The abutment part 63 abuts against the inner wall of the door frame 2, and the flexible hose 62 is connected to the adhesive outlet 61.

[0045] The sealant container 7 is equipped with a delivery module, which delivers the sealant into the hose 62 and finally out through the outlet 61. The outflowing sealant moves with the rubber block 6, thus applying a layer of sealant to the contact edge between the glass 22 and the door frame 2. This strengthens the bond between the door frame 2 and the glass 22, further improving their seal. It also covers the edges of the film layer on the surface of the glass 22.

[0046] After the sealant is applied, the electric actuator 5 is retracted to raise the rubber block 6 to its highest position. Then, air is injected into the air cushion 8 to prepare for removing the top cover 3.

[0047] A cylinder 2 19 is fixedly installed on the top of the top cover 3. The extension and retraction of the cylinder 2 19 controls the raising and lowering of the top cover 3.

[0048] In summary, this processing device for pre-bonding glass on the door panel of a steam oven uses a top cover 3 to cover the door frame 2, aligning the annular tube 4 with the glass inside the door frame 2 for film coating. Using an electric push rod 5, rubber block 6, and sealing tube 7, a sealing ring is applied after the glass 2 is coated, strengthening the door frame 2, the glass 22, and the film layer on the surface of the glass 22, further improving the sealing effect. The air pump 10, air cushion 8, and sliding rod 9 work together to shield and seal the equipment inside the top cover 3, thus preventing the loss of internal evaporation molecules. This simplifies the complex operation of traditional processes.
