[0001] The invention relates to the field of automation technology, and in particular to a purely mechanical automatic turning and restoring device. Background Art

[0002] At present, in the medical and semiconductor fields, the production of products such as transparent mobile phone shells and medical protective masks generally requires a series of process flows such as dispensing, lighting, and baking in a closed tunnel furnace at a relatively long distance (50 meters). Due to product process requirements, the product needs to be flipped (90°) in different sections, and the flipped state of the product needs to be automatically maintained for a relatively long distance (20 meters), and then restored to the state before flipping. At present, the commonly used method is to install a motor or cylinder in the tunnel furnace, and use PLC to control the clamped product to flip, maintain and restore in the tunnel furnace. Due to the high temperature in the tunnel furnace (80°C), the motor or cylinder and the air pipe wire need to be made of high temperature resistant materials, and the motor is in this high temperature state for a long time, unable to dissipate heat, and has a high failure rate. The cost of maintenance and replacement is large, which seriously affects the production efficiency. Therefore, a purely mechanical automatic flipping and recovery device is urgently needed to solve the above problems. Summary of the invention

[0036] Working principle of the present invention:

[0037] Continue to refer to Figures 1 to 5 As shown, in this embodiment, the device is applied in a high-temperature tunnel furnace 9, and the translation drive mechanism 7 includes a U-shaped translation guide rail module, a drag chain assembly, and a motor for driving the drag chain assembly to operate; the translation guide rail module is arranged in the tunnel furnace, and the two vertical ends of the U-shape of the translation guide rail module are arranged to pass through the tunnel furnace; the ends of the two vertical ends of the U-shape of the translation guide rail module are respectively the feeding end and the discharging end, and the motor is installed on the outside of the tunnel furnace, so that the products can be continuously conveyed to the tunnel furnace for processing, and then the processed products are conveyed out of the tunnel furnace for unloading; in this embodiment, a limiting wheel is also provided on one side of the sliding seat 8, The sliding seat 8 is arranged on the translation guide rail module through the limiting wheel, which can ensure the stability of its sliding; a fixing clamp 81 is also provided on the other side of the sliding seat 8, and the fixing seat 3 can be detachably installed on the sliding seat 8 through the fixing clamp 81, which is convenient for disassembly and assembly, and convenient for placing and removing products; the upper slope guide rail 1 and the lower slope guide rail 2 are arranged in the tunnel furnace, and the distance between the two is adjustable, which can be freely set according to the use requirements (the distance to keep the product in a horizontal state). Compared with the traditional transmission method using a motor or a cylinder, the device is convenient to adjust the distance that the product needs to move in a horizontal state, which is convenient and efficient. When working specifically:

[0038] First, the product is clamped and fixed by the rotating clamp 42, and the fixed seat 3 is installed on the sliding seat 8 by the fixing clamp 81. Initially, the clamping plate 41 of the clamping assembly 4 and the product are in a vertical state; then, the translation drive mechanism 7 drives the fixed seat 3 to drive the product to translate into the tunnel furnace. Before passing through the upper inclined guide rail 1, the product is always in a vertical state; then, the fixed seat 3 arrives at the entrance of the upper inclined guide rail 1, and under the drive of the translation drive mechanism 7, the sliding wheel 63 of the upper guide wheel shaft 61 will rise along the inner wall slope of the guide cavity, and the sliding wheel 63 of the lower guide wheel shaft 62 will contact the bottom wall of the guide rail housing 11 to guide it and ensure the rolling stability; and the lifting guide rod 51 will pass through the guide slide groove 12 and continue to translate forward, and as the sliding wheel 63 of the upper guide wheel shaft 61 rolls upward, it will drive the lifting guide rod 51 upward The lifting guide rod 51 will move upward, and then the lifting and rotating block 52 will drive the clamping plate 41 and the product to slowly rotate upward. When the sliding wheel 63 rolls to the exit of the upper slope guide rail 1, the clamping plate 41 drives the product to flip over 90°. At this time, the product flips from a vertical state to a horizontal state. In addition, during the upward movement of the lifting guide rod 51, the magnet mounting seat 54 will also be driven to perform a synchronous upward movement. When the sliding wheel 63 of the upper guide wheel shaft 61 rolls to the exit of the upper slope guide rail 1, the magnet assembly 55 of the magnet mounting seat 54 is just adsorbed together with the guide block 32 made of magnetic material. Under the action of the magnetic attraction, the product will continue to remain in a horizontal state. Therefore, there is no need to set any supporting mechanism in the area between the upper slope guide rail 1 and the lower slope guide rail 2, so that the product can always remain in a horizontal state within any distance, which is convenient and practical.

[0039] Driven by the translation drive mechanism 7, the product moves horizontally for a distance and arrives at the entrance of the lower slope guide rail 2; at this time, the sliding wheel 63 of the upper guide wheel shaft 61 enters the guide cavity of the lower slope guide rail 2, and the inner wall of the top of the guide cavity will squeeze the sliding wheel 63, thereby driving the lifting guide rod 51 to descend. During the descent of the lifting guide rod 51, the magnet assembly 55 and the guide block 32 will be driven to gradually separate, thereby driving the clamping plate 41 and the product to slowly rotate downward and reset. When the sliding wheel 63 slides out of the exit of the lower slope guide rail 2, the clamping plate 41 just flips back 90°, so that the product returns to its original vertical state. Driven by the translation drive mechanism 7, it continues to perform translational movement along the translation guide rail module until the material flows out of the tunnel furnace. It is convenient and practical, and compared with the conventional method of using cylinders, motors, etc. to achieve flipping, the device can greatly reduce costs, and is suitable for small spaces and harsh environments, with strong versatility.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
