Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle for a horizontally stationary tunnel furnace. Background Technology

[0002] In the production of PCB boards, LED light sheets, and COB display boards, baking is required. To ensure product quality, the products need to be left to cool completely or wait for the next process after baking. Current methods use tunnel ovens and settling machines to perform the baking and settling processes separately, necessitating the installation of loading / unloading and transfer equipment between the two machines, resulting in significant space requirements. Furthermore, traditional tunnel ovens and settling machines often use chain conveyors with looped circuits during loading, palletizing, and material transport. Chain mechanisms inevitably generate metal shavings, which can lead to product defects, especially for materials like PCB boards, LED light sheets, and COB display boards.

[0003] Therefore, the inventors of this application have researched a high-purity horizontal static tunnel oven. Through a novel structural design, the use of transmission components such as chains that easily generate metal shavings in the material transport space is avoided. Furthermore, baking and static placement are integrated, effectively preventing contamination of materials by metal shavings, ensuring product quality, and improving equipment integration and production efficiency. To adapt to the new equipment structure and operating mode, the applicant has also designed corresponding carriers for placing and transporting materials such as PCB boards, LED light sheets, or COB display boards.

[0018] 4. Enhanced structural stability: The four corners of the inner side of the support frame are fixed with reinforcing ribs, which enhances the overall structural stability of the vehicle and ensures that it will not be deformed or damaged during transportation and stacking, thus extending the service life of the vehicle.

[0019] 5. Facilitates stacking and unstacking: The width of the support block is greater than the width of the support frame.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0029] Example 1: The carrier used in this example of the horizontal static tunnel oven is designed for use with the horizontal static tunnel oven for drying and settling PCB boards. Figures 1-5 As shown, the carrier for the horizontally stationary tunnel furnace includes a support frame 10. Positioning pins 30 are fixedly connected to the four corners of the upper end of the support frame 10. Support blocks 20 are fixedly connected to the four corners of the bottom surface of the support frame 10. Positioning holes 201 are opened in the support blocks 20. The center lines of the positioning pins 30 and the positioning holes 201 located at the same corner coincide. Ventilation holes 101 are opened on the front and rear sides of the support frame 10. A support mechanism is provided on the inner side of the support frame 10. The support mechanism consists of four sets of front and rear symmetrical wedge-shaped brackets 401.

[0030] In this embodiment, the wedge-shaped bracket 401 has four steps on its inclined side, which can be used to accommodate four different PCB board sizes.

[0031] In order to improve the circulation of hot air during the drying process, in this embodiment, ventilation holes 101 are also opened on the left and right sides of the support frame 10, and the ventilation holes 101 are designed as elongated round-headed shapes, thereby increasing the area of ​​the ventilation holes 101 while ensuring the strength of the support frame 10.

[0032] To maintain the stability of the vehicle, the four corners of the inner side of the support frame 10 are fixedly connected with reinforcing ribs 50.

[0033] In order to facilitate the contact between the lower support frame 10 and the middle part of the upper support block 20 after the equipment supports the two sides of the support block 20 during the stacking process, the width of the support block 20 is set to be greater than the width of the support frame 10. This allows for convenient stacking and unstacking in conjunction with the support block containing the clearance groove in the horizontally placed tunnel furnace.

[0034] Example 2: The carrier used in this example of the horizontal static tunnel oven is designed for use with the horizontal static tunnel oven for drying and settling COB display panels, such as... Figure 6 As shown, the carrier for the horizontally stationary tunnel furnace includes a support frame 10. Positioning pins 30 are fixedly connected to the four corners of the upper end of the support frame 10. Support blocks 20 are fixedly connected to the four corners of the bottom surface of the support frame 10. Positioning holes 201 are opened in the support blocks 20. The center lines of the positioning pins 30 and positioning holes 201 located at the same corner coincide. Ventilation holes 101 are opened through the front and rear sides of the support frame 10. A support mechanism is provided inside the support frame 10. This support mechanism consists of support plates 402, support rods 403, and auxiliary support plates 404. In this embodiment, two support plates 402 are fixedly connected to the front and rear ends of the support frame 10, and five support rods 403 are fixedly connected to the left and right ends of the support frame 10. Holes for the support rods 403 to pass through are opened on the support plates 402. Two auxiliary support plates 404 are fixedly connected between adjacent support plates 402. Since the COB display board cannot be supported by the edges like a PCB board, in this embodiment, a support plate 402 and a support rod 403 arranged horizontally and vertically are used for joint support. At the same time, an auxiliary support plate 404 can be used to provide auxiliary support or positioning for the COB display board.

[0035] As can be seen from Embodiments 1 and 2, the support mechanism of this utility model can be adaptively adjusted according to the material to be supported. Therefore, without departing from the concept or basic features of this utility model, support mechanisms with other structures should also fall within the claims of this utility model.
