Description

Technical Field

[0001] The invention relates to a drying static device, in particular to a high-cleanliness static tunnel furnace. Background Art

[0002] In the production process of PCB boards, LED lamps or COB display boards, baking is required. In order to ensure product quality, the products need to be left to stand for a certain period of time after baking to allow them to fully cool down or wait for the next process. The existing method is to use a tunnel furnace and a standing machine to respectively achieve the baking and standing processes, which requires loading and unloading and transmission equipment to be set between the two devices, which occupies a large area.

[0003] In the process of loading, stacking and conveying materials, the conveyor belts of traditional tunnel furnaces and static machines are mostly in the form of circulating loop chains. For example, in the invention patent of a fully automatic high-temperature static tunnel furnace and a high-temperature static process with the authorization announcement number CN110132004B, the material movement is achieved by pushing the material cart with a chain. Another example is the PCB board static machine with the application publication number CN116022540A, which supports the board rack through the mounting parts on the chain to achieve the first-in-first-out and static of the board rack and the materials. However, the inventor of the present application found in the actual use that in the above method, the chain mechanism will inevitably produce metal debris during the transmission process. For materials such as PCB boards, LED light sheets or COB display boards, the presence of metal debris will cause the product to be unqualified, especially for PCB boards, the metal debris on them is difficult to detect, but it will have a fatal impact on the performance of the PCB boards.

[0035] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0036] 1. Ensure product quality and reduce defective rate: Traditional tunnel furnaces and static machines mostly use chains in the process of loading, stacking and material transportation, which are prone to produce metal debris. Metal debris is a fatal defect for materials such as PCB boards, LED lamps or COB display boards, which will lead to unqualified products. The present invention avoids the contact between transmission parts such as chains that are prone to produce metal debris and the material transmission space through a new structural design, thereby effectively preventing the contamination of materials by metal debris, ensuring product quality, reducing the product defective rate caused by metal debris, and improving the market competitiveness of products.

[0037] 2. High equipment integration and space saving: The tunnel furnace and the stationary equipment are integrated into one, which changes the way the two are set separately in traditional production. There is no need to set up additional loading and unloading and transmission equipment between the two devices, which greatly reduces the overall footprint of the equipment and makes more efficient use of the production space. For companies with limited plant space, it can effectively reduce site costs and improve the flexibility of production layout.

[0038] 3. Improve production efficiency: During the entire production process, materials do not need to be frequently transferred and loaded and unloaded between different equipment, which reduces the waiting time and possible poor connection problems during the transfer process, allowing the materials to complete the baking and standing processes more smoothly and continuously, thereby effectively improving production efficiency and shortening the product production cycle.

[0039] 4. Smooth and reliable operation, extending the life of the equipment: key components such as the palletizing components and stepper components adopt carefully designed drive and transmission structures. For example, the palletizing drive component increases the lifting torque and reduces the pallet movement speed through the reducer, so that the carrier can stack smoothly; the stepper component achieves smooth stepping transportation through the jacking drive component, bevel gear set, cam and other structures. These designs make the equipment more stable and reliable during operation, reduce equipment wear and failure caused by impact, vibration, etc., thereby extending the service life of the equipment and reducing the maintenance cost and replacement frequency of the equipment.

[0040] 5. Strong adaptability and high flexibility: The length of the tunnel furnace and the horizontal stationary section can be adjusted according to actual production needs, which can meet the requirements of different materials and different processes for baking and stationary time. In addition, auxiliary cooling or cleaning equipment can be set in the horizontal stationary section as needed, which further enhances the adaptability and flexibility of the equipment and enables it to better adapt to the changing production environment and process requirements.

[0041] 6. High degree of automation, reducing labor intensity: The entire production process is highly automated. All links from material loading, stacking, baking, standing to unloading are automatically completed by the equipment. There is no need for manual repetitive operations, which greatly reduces the labor intensity of workers. At the same time, it also reduces the impact of human factors on the production process and product quality, and improves the stability and consistency of production.

[0082] like Fig. 9As shown, the carrier reflux assembly 4 includes a reflux drive 41, a transmission member 42, a reflux rotating rod 43, a circulating chain roller 44, a guide frame 45, a guide roller 46 and a stopper 47. The reflux drive 41 is installed on the frame, and the reflux rotating rod 43 is rotatably arranged on the lower side of one end of the frame. The reflux drive 41 drives the reflux rotating rod 43 to rotate through the transmission member 42. The two ends of the reflux rotating rod 43 each drive a circulating chain roller 44 to rotate in a circular manner. The circulating chain roller 44 passes through the carrier displacement assembly 3, the stacking assembly 5, the tunnel furnace 6 and the bottom of the horizontal stationary section 7. A guide frame 45 is arranged on the side where the two circulating chain rollers 44 are away from each other, and a plurality of guide rollers 46 are arranged on the side where the two guide frames 45 are close to each other. The stopper 47 is arranged below the stacking assembly 5 at the loading end, and is used to place a carrier 9 through only after the bracket 31 moves to the bottom, so as to prevent the carrier 9 from interfering with the up and down movement of the bracket 31.

[0083] In this embodiment, the reflux drive member 41 is a motor. Since the guide roller 46 is located at the bottom, the metal debris generated by it will not fall onto the carrier 9 or the material. Based on cost, stability, convenience and other factors, the guide roller 46 is still used here. In other embodiments of the present application, belts, sticks, gears and other methods can also be used to drive the carrier 9 to reflux. Since the transmission member 42 is located outside the equipment carrier 9 and the material running space, the metal debris generated by it will not enter the equipment and affect the material. Therefore, in this embodiment, the transmission member 42 uses a sprocket group. In other embodiments of the present application, the transmission components such as gears, couplings, belts and the like can also be used to achieve the transmission of motion.

[0084] The operation process of the high-clean horizontal static tunnel furnace of the present application is as follows: the material conveying line 1 conveys the material that has completed the previous process to the feeding end side of the horizontal static tunnel furnace, and then the material is taken out by the material taking manipulator 2 and placed on the carrier 9 lifted up by the carrier displacement component 3. The material is transported to the stacking component 5 by the carrier displacement component 3 along with the carrier 9 for stacking. After stacking, the material is gradually taken into the tunnel furnace 6 for drying by the stepping component 8, and then enters the horizontal static section 7 for static. After static, it enters the stacking component 5 on the side of the unloading end for unloading. After unloading, the material is still transported to the direction of the lower feeding end along with the carrier 9 by the carrier displacement component 3 on the side of the unloading end. Then the material is taken out from the carrier 9 by the material taking manipulator 2 and placed on the material conveying line 1 for transportation to the next process. After the material is taken out, the carrier 9 is further transported by the carrier displacement component 3 to the carrier reflux component 4 for reflux.
