DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-9 , the present invention provides the following technical solutions:

[0033] Embodiment 1:

[0034] In this embodiment, in order to solve the problems existing in the prior art, the hot air can be blown more evenly and fully on the workpiece to improve the baking efficiency, so the following scheme is disclosed, specifically as follows: Figure 3As shown, the baking machine includes a body 1 and an operating area 2 arranged on the vertical surface of the body 1, and an upper cover 3 hinged on the top of the baking space inside the body 1. A hot air duct 4 is arranged in the baking space. The hot air duct 4 is symmetrically distributed on the front and rear side walls of the baking space, and a nozzle for spraying hot air is installed on the hot air duct 4. Drying strips 5 with hollow structures distributed at equal intervals are also installed on the bottom wall of the baking space. The upper end surface of the drying strip 5 is also provided with air holes 6. The drying strip 5 and the hot air duct 4 are both connected to a hot air supply mechanism 9 through a connecting pipe 8. The drying strip 5 and the hot air duct 4 are also connected to a hot air supply mechanism 9 through a connecting pipe 8. The drying strip 5 and the hot air duct 4 are also connected to a hot air supply mechanism 9 through a connecting pipe 8. The gear 10 is fixedly installed at the end of the hot air duct 4, and the gears 10 on the upper and lower adjacent hot air ducts 4 are meshed with each other. A motor 11 is also installed inside the body 1. The output end of the motor 11 is connected to a hot air duct 4 on the front and rear sides through a pulley mechanism. The motor 11 is used to drive the hot air duct 4 to reciprocate. The output shaft of the motor 11 reciprocates under the control of the motor 11, so Figure 3 The hot air pipe 4 in the middle position of the front and rear sides will be in a reciprocating rotation state. Therefore, under the meshing transmission action between the gears 10, all the hot air pipes 4 located in the baking space will be in a reciprocating rotation state. Therefore, the hot air flow will also be in a swinging state accordingly. Multiple hot air pipes 4 swing at the same time, thereby achieving more sufficient and uniform baking, and the hot air will also be blown out from the air holes 6 opened on the surface of the drying strip 5 accordingly, so that the bottom of the workpieces piled up in the basket will also be dried by the corresponding hot air.

[0035] When batch drying of workpieces is performed, especially the terminal devices stacked in the basket, the gaps between each other are small. Even if the hot air is in a swinging state, it is difficult to dry the terminals stacked inside. Therefore, in order to solve this problem, the following solution is also disclosed in this embodiment. Figure 4As shown, a cylinder 7 is also installed on the upper end surface of the drying strip 5, and the top of the cylinder 7 is used to directly contact the net basket, and the cylinder 7 and the air holes 6 are staggered, and a vibration mechanism is provided in the drying strip 5, and the vibration mechanism is used to make the cylinder 7 in a vibrating state during baking, and the vibration mechanism includes a raised block 14 with an arc-shaped cross-section, and the raised block 14 is fixed at an equal angle in the inner wall of the cylinder 7, and a vertical shaft 12 distributed vertically is arranged coaxially in the cylinder 7, and the outer wall of the vertical shaft 12 is installed with a striking rod 13 distributed horizontally at an equal angle, and the middle section of the striking rod 13 is connected by a spring, and a driving mechanism is installed at the bottom end of the vertical shaft 12, and the driving mechanism is used to drive the vertical shaft 12 to rotate, and the driving mechanism is composed of a first paddle 28, and the first paddle 28 is fixed at an equal angle at the bottom end of the vertical shaft 12, And the first paddle 28 is located inside the drying strip 5. Since the bottom end of the mesh basket is in direct contact with the top end of the cylinder 7, when the hot air flows at a high speed inside the drying strip 5, it will drive the vertical shaft 12 to rotate through the first paddle 28. Therefore, the striking rod 13 installed on the vertical shaft 12 will rotate synchronously. During the rotation, the outer end of the striking rod 13 will hit the outer wall of the protruding block 14 accordingly, and during the continuous rotation of the vertical shaft 12, the spring part of the striking rod 13 will bend accordingly to ensure that the vertical shaft 12 can continue to rotate normally. Therefore, the striking rod 13 can cyclically knock on the outer wall of the protruding block 14, thereby driving the mesh basket containing the workpiece to be in a vibrating state through the cylinder 7. Therefore, the hot air flow can more easily enter the stacked terminals, thereby achieving the purpose of using the flow of hot air flow to put the workpiece in a vibrating state.

[0036] Embodiment 2:

[0037] Since the split terminal itself is a split structure, that is, the contact surface with the outside world is more, which makes it easy for more water vapor to stay inside it. Therefore, in order to better bake such workpieces, the following scheme is also disclosed in this embodiment, specifically as follows: Figure 8 As shown, a placement rack 15 is also provided in the baking space, and a clamping column 16 is installed on the placement rack 15. The clamping column 16 is used to place the split terminal, and the bottom end of the clamping column 16 is installed on the top end of the positioning cylinder 17. The bottom end of the positioning cylinder 17 passes through the strip rod at the bottom end of the placement rack 15 and coincides with the channel 18. The channel 18 is opened inside the cylinder 7. The placement rack 15 is composed of a plurality of strip rod structures distributed longitudinally and transversely. The strip rod at the bottom end is used to contact the body 1. The clamping column 16 installed on the top end of the strip rod is used to contact the inner wall of the split terminal and install the terminal, and the positioning cylinder 17 at the bottom end of the clamping column 16 is used to be inserted into the channel 18 in the cylinder 7 to ensure that the placement rack 15 can be stably placed in the baking space.

[0038] The inner wall of the terminal of the split structure is attached to the clamping column 16, and the airflow cannot fully contact the inner wall of the terminal, resulting in low drying efficiency. Therefore, in order to solve this problem, the following solution is also disclosed in this embodiment, specifically as follows: Figure 7-8 As shown, the interior of the column 16 is a hollow structure, which is connected to the through hole 20 opened on the surface of the column 16, and the bottom end of the column 16 is connected to the positioning cylinder 17 of the hollow structure. The air supply device is used to connect the positioning cylinder 17 and the drying strip 5. The air supply device includes a top plate 19, which is vertically elastically slidably connected to the inside of the channel 18, and the top opening diameter of the channel 18 is smaller than the diameter of the lower half. The edge of the top plate 19 in the initial state is attached to the inner wall of the upper half of the channel 18, and the top plate 19 is rotatably connected to the top of the vertical shaft 12, and the vertical shaft 12 is vertically slidably connected to the top plate 19. Connected in the cylinder 7, when the placement rack 15 is placed in the baking space, the bottom end of the positioning cylinder 17 is inserted into the channel 18, and the rod-type structure with equal angles distributed at the bottom end of the positioning cylinder 17 fits on the top wall of the top plate 19. Under the action of gravity, the positioning cylinder 17 presses the top plate 19 downward and moves the top plate 19 downward, so the aperture of the channel 18 around the top plate 19 becomes larger, and the hot air in the drying strip 5 enters the positioning cylinder 17 through the channel 18, and further enters the internal space of the card column 16, and is blown out from the perforation 20, so that the inner wall of the terminal fitted on the card column 16 is fully dried.

[0039] In order to further improve the baking efficiency of the terminal, the present embodiment also discloses the following scheme, specifically: Figure 7-9 As shown, the bottom end of the post 16 is rotatably mounted on the top end of the positioning tube 17, and a ball 23 is embedded in the top end of the post 16, and the positioning tube 17 is connected to a rotating device, which is used to drive the positioning tube 17 to rotate in the terminal. The rotating device includes a vertical rod 22 and a second paddle 21, and the vertical rod 22 is vertically rotatably mounted in the positioning tube 17, and the top end of the vertical rod 22 is fixed to the side wall of the post 16, and the second paddle 21 fixed to the bottom end of the vertical rod 22 is located inside the positioning tube 17. When the airflow flows in the positioning tube 17, the vertical rod 22 will be synchronously in a rotating state driven by the second paddle 21, so the post 16 will rotate synchronously, and because the inner top end of the terminal fits and presses on the ball 23, the relative rotation between the ball 23 and the post 16 will make the terminal in a relatively static state when the post 16 rotates, so the hot airflow ejected from the surface of the post 16 can act more evenly and comprehensively on the inner wall of the terminal.

[0040] In this embodiment, in order to ensure that the hot air flow can be used more efficiently, the following solution is also disclosed in this embodiment. Figure 8-9As shown, a collar 27 is rotatably mounted on the vertical shaft 12, and the outer surface of the collar 27 is hinged to the top of the inclined rod 26, and the bottom end of the inclined rod 26 is hinged to the outer end of the push rod 25. A sealing plate 24 is also fixed to the inner end of the push rod 25, and the push rod 25 is horizontally slidably connected to the inside of the drying bar 5 through a spring. The coverage area of ​​the sealing plate 24 is larger than the cross-sectional area of ​​the air hole 6. When the top plate 19 drives the vertical shaft 12 to move downward, the push rod 25 will correspondingly drive the sealing plate 24 to move under the pushing action of the inclined rod 26. Therefore, the sealing plate 24 will correspondingly block the air hole 6 on the side of the cylinder 7 to ensure the hot air flow in the drying bar 5. After the placement rack 15 is placed in the baking space, only the cylinder 7 connected thereto will spray hot air flow, thereby ensuring the drying effect and energy saving effect.
