Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1-6 , an embodiment provided by the present invention: An oven for placing cob light source substrates, including an oven body 1 and a movable door 2. The movable door 2 is movably connected to the surface of the oven body 1. A placement rack 3 is placed inside the oven body 1. A transportation component 4 is provided at the bottom of the placement rack 3. A limiting component 5 is provided inside the placement rack 3;

[0027] The transportation component 4 includes a fixed block 41, a connecting block 42, a first connecting rod 43, a moving roller 44 and a baffle 45. A fixed block 41 is provided at the bottom of the placement rack 3. A connecting block 42 is provided at the bottom of the fixed block 41. A first connecting rod 43 is provided inside the connecting block 42. A moving roller 44 is provided at the bottom of the first connecting rod 43. A baffle 45 is provided on the outer side of the connecting block 42;

[0028] Through the settings of the transportation component 4 and the limiting component 5, this device solves the problems that the existing light source board oven equipment cannot be replaced quickly and transported flexibly in a centralized batch manner, thus affecting the work efficiency.

[0029] Furthermore, the limiting component 5 includes a movable slot 51, a limiting plate 52 and a spring 53. A movable slot 51 is opened in the fixed block 41. A limiting plate 52 is movably connected inside the movable slot 51. The limiting plate 52 is T-shaped and has an arc-shaped bottom. The diameter of the limiting plate 52 is adapted to the movable slot 51. A spring 53 is provided at the upper end of the limiting plate 52. One end of the spring 53 abuts against the limiting plate 52, and the other end of the spring 53 abuts against the inner wall of the movable slot 51. As Figure 6 shown, this structure is used to push the limiting plate 52 to move upward when the first connecting rod 43 contracts inside the oven body 1, squeeze the spring 53, and cause the spring 53 to deform. When the placement rack 3 is taken out after baking, under the restoring action of the spring 53, the limiting plate 52 is pushed to move downward, and the limiting plate 52 pushes the lower first connecting rod 43 until it is parallel to the limiting plate 52, thereby limiting the first connecting rod 43.

[0030] Furthermore, two groups of fixed blocks 41 are respectively located on the left and right sides of the bottom of the placement rack 3 and are fixedly connected to the placement rack 3. The top of the connecting block 42 is fixedly connected to the fixed block 41 and is located on the front and back sides of the fixed block 41. The upper end of the first connecting rod 43 is rotatably connected to the connecting block 42. The other end of the first connecting rod 43 is rotatably connected with a moving roller 44. The top of the baffle 45 is fixedly connected to the fixed block 41. The inner side of the baffle 45 is attached to the connecting block 42. The baffle 45 limits the movement range of the first connecting rod 43. As Figure 5 shown, this structure is used to facilitate the folding of the placement rack 3 through the rotatably connected first connecting rod 43, which is convenient for storage inside the oven body 1. During transportation, the first connecting rod 43 is rotated in the opposite direction for support, and the moving roller 44 is used for movement.

[0031] Furthermore, guiding rollers 6 are fixedly installed on the left and right sides of the placement rack 3. A guide rail 7 is fixedly connected to the inner wall of the oven body 1. The diameter of the guide rail 7 is adapted to the guiding rollers 6. As Figure 4 shown, this structure is used to move the guiding rollers 6 inside the guide rail 7 to play a guiding role for the placement rack 3 so that it is stored in a fixed position.

[0032] Further, holes are equidistantly arranged in the placement rack 3, and positioning rods 8 are inserted into the holes. The top ends of the positioning rods 8 are fixedly connected with limit blocks. As Figure 5 shown, this structure is used to facilitate the fixation of the light source board through the arrangement of the positioning rods 8, and avoid the phenomenon of slipping and scattering during the movement.

[0033] Further, a second connecting rod 9 is fixedly connected to the inner side of the first connecting rod 43, and the second connecting rod 9 is located at the central position of the first connecting rod 43. As Figure 3 shown, this structure is used to connect the two groups of first connecting rods 43 through the arrangement of the second connecting rod 9 to keep them consistent.

[0034] Further, an auxiliary roller 10 is rotatably connected to the outer surface of the first connecting rod 43, and an observation window 11 is fixedly installed in the movable door 2, which is convenient for users to observe the internal situation of the oven body 1 from the outside. As Figure 5 shown, this structure is used to facilitate the movement of the first connecting rod 43 in the oven body 1 with the help of the auxiliary roller 10 when the first connecting rod 43 is retracted through the arrangement of the auxiliary roller 10, so as to avoid abrasion or jamming inside the oven body 1 and make the first connecting rod 43 move stably in the oven body 1.

[0035] Working principle: When in use, as Figure 1 and Figure 2 shown, after the light source board inside the oven body 1 is baked, the movable door 2 is opened and the placement rack 3 is taken out. As Figure 4 and Figure 5 shown, when the placement rack 3 moves outwards, the guiding rollers 6 on both sides move along the guide rails 7. As the placement rack 3 moves, a group of first connecting rods 43 at the front side rotate downwards. At this time, as Figure 6 shown, under the elastic action of the spring 53, the limit plate 52 is pushed to move downwards along the movable groove 51, and the first connecting rod 43 is pushed until the first connecting rod 43 is parallel to the limit plate 52. When the placement rack 3 is completely taken out, the other group of first connecting rods 43 at the rear side is the same. When the four groups of first connecting rods 43 are in a vertical state, they are moved with the help of the moving rollers 44 at the bottom, and then another placement rack 3 that has not been baked is pushed into the oven body 1. As Figure 5 and Figure 6As shown, the guiding rollers 6 are in one-to-one correspondence with the guide rails 7, and then the placement rack 3 is pushed into the oven body 1. As the placement rack 3 goes deeper, the first connecting rod 43 at the rear rotates towards the center of the placement rack 3. While rotating, it pushes the limiting plate 52 to contract upwards, squeezing the spring 53 and deforming the spring 53. After the first connecting rod 43 at the rear completely fits against the bottom of the fixed block 41, the worker holds the second connecting rod 9 at the bottom and drives the first connecting rods 43 at the front sides on both sides to rotate towards the center position of the placement rack 3, and moves inside the oven body 1 with the aid of the auxiliary rollers 10, greatly saving the time for replacing the light source board and improving work efficiency. The above is the entire working principle of the present utility model.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
