[0028] In this technical solution, the support seat includes a support frame formed by splicing conventional structures such as profiles and door panels and a workbench fixed to the top of the support frame, which is used to make a feeding chain and a box body. The box body is spliced ​​by conventional wall panels, and the inner walls and gaps of the wall panels are filled with thermal insulation cotton to improve the thermal insulation capacity of the box body. The side walls of the box body are provided with an openable and closable inspection door through hinges, etc. The specific structure belongs to the prior art and will not be described in detail here. The motor uses a conventional servo motor to drive the chain to feed step by step. The tray is formed according to the parts such as the rotor to be dried as needed. The shifting device on the side of the feed port puts the parts to be dried into the corresponding tray, and the chain drives the tray to enter the baking chamber from the feed port. After drying, the chain drives the tray to enter the cooling chamber from the connecting door. After cooling, the parts in the tray are sent out from the discharge port and taken out by the shifting device on the side of the discharge port, and can be directly put into the next process for continued assembly. The whole process does not require human participation, avoiding the staff working in a high temperature environment, and the drying and cooling of the materials are completed automatically, thereby improving work efficiency.

[0029] For example, see Figures 1 to 5 As shown, the support seat 1 includes a support frame and a workbench arranged on the top of the support frame, the motor 22 is fixed to the bottom surface of the workbench, and its output shaft passes through the workbench and is driven and connected to the chain 21 through a driving sprocket 24.

[0030] In this technical solution, the workbench is assembled in one piece or in multiple pieces and horizontally arranged on the top of the support frame. The motor is vertically fixed to the bottom surface of the workbench through a conventional motor seat. Its output shaft is driven and connected to the driving shaft of the active sprocket through a conventional coupling, etc. The motor output shaft is also sleeved with a conventional dividing plate, and cooperates with existing sensors, etc. to realize the step-by-step drive chain of the motor. The tensioner is rotatably set on the workbench and engages with the chain to ensure the tension of the chain and improve the feeding accuracy. The driven sprocket is rotatably set on the workbench through a conventional bearing seat and rotating shaft, etc., and is used to cooperate with the active sprocket to ensure the normal operation of the chain.

[0031] For example, see Figure 3As shown, the chain 21 is arranged in the baking chamber in a serpentine rotation through a plurality of steering sprockets 27 .

[0032] In this technical solution, the steering sprocket is rotatably set on the workbench through a conventional bearing seat and a rotating shaft, the chain changes its direction through the steering sprocket, and is serpentine-rotated in the baking chamber, thereby extending the time the tray stays in the baking chamber, improving the drying effect, and shortening the length of the box. A support platform corresponding to the chain is set on the top surface of the workbench. The support platform is made of self-lubricating nylon, etc., and a slide groove corresponding to the chain is opened on the top of the support platform to ensure smooth operation of the chain.

[0033] For example, see Figure 1 and Figure 2 As shown, a plurality of centrifugal fans 6 are arranged at the top of the inner wall of the baking chamber, and the heating device 4 includes heating components respectively arranged on both sides of the centrifugal fans 6 , and the heating components include a plurality of heating tubes fixed to the box body 3 .

[0034] In this technical solution, the centrifugal fan can be selected from the existing structure, and its driving motor is fixed to the top of the box body through a mounting plate, and the output shaft of the driving motor passes through the top surface of the box body and drives the centrifugal fan. The centrifugal fan stirs the air in the baking chamber to improve the uniformity of the temperature in the baking chamber; a mounting groove for installing a heating tube is provided at the top of the box body, and the heating tube is fixed to the mounting groove through a mounting strip, and a cover is provided at the top of the mounting groove to encapsulate the heating tube and cables to prevent short circuits caused by debris falling into the groove.

[0035] For example, see Figures 4 to 6 As shown, an air guide plate 7 is provided between the centrifugal fan 6 and the heating assembly.

[0036] In this technical solution, the air guide plate includes a mounting horizontal plate connected to the inner wall of the box body, and a avoidance groove corresponding to the heating device and a through hole corresponding to the centrifugal fan are arranged in the mounting horizontal plate. A surrounding plate corresponding to the centrifugal fan and an air guide strip guiding the heating device are arranged outside the through hole to guide the wind force of the centrifugal fan to the heating device.

[0037] For example, see Figure 1 and Figure 2 As shown, the top of the box body 3 is provided with an exhaust pipe 8 connected to the baking chamber and a thermocouple 9 extending to the baking chamber.

[0038] In this technical solution, the exhaust pipe is of conventional structure, and conventional adjustment is provided inside the exhaust pipe to adjust the cross-section of the exhaust pipe connected to the outside, and cooperate with the heating device to adjust the temperature in the baking chamber. The thermocouple is of conventional structure, and a single or multiple ones are set simultaneously to monitor the temperature in the baking chamber. A cover is set at the top of the box to protect the thermocouple.

[0039] For example, see Figures 1 to 5As shown, a plurality of cooling fans 10 are arranged on the side wall of the cooling cavity, and an exhaust pipe 20 is arranged on the top of the cooling cavity.

[0040] In this technical solution, the cooling fan uses an existing cooling fan and is set on the side of the corresponding part of the chain. The height of the setting is aligned with the pallet, which can quickly cool the dried pallets and parts, making it convenient for the parts to be directly added to the subsequent production process. The exhaust duct draws away the hot air flow in the cooling chamber and connects it to an external processing device or recovery device, etc., to improve the cooling efficiency.

[0041] For example, see Figures 1 to 5 As shown, a plurality of positioning pins 211 protrude from the top of the chain 21 , and the tray 23 is inserted into the positioning pins 211 .

[0042] In this technical solution, the tray includes a base inserted into the positioning pin and a cylinder fixed to the top of the base, which is convenient for disassembly and assembly. The positioning pin is connected to the pin shaft corresponding to the chain or is extended by the pin shaft of the chain.

[0043] For example, see Figure 7 As shown, the material moving device 5 includes a mounting frame 51 fixed to the workbench, a shift cylinder 52 arranged on the mounting frame 51, a lifting cylinder 53 driving the shift cylinder 52 and a clamping cylinder 54 fixed to the lifting cylinder 53, and the fingers of the clamping cylinder 54 are respectively connected to the clamping blocks 55.

[0044] In this technical solution, the mounting frame includes a supporting column and a connecting plate, etc. The shift cylinder drives the gripper cylinder to reciprocate above the pallet and the external storage device, etc., to deliver the dried parts into the pallet or take out the dried parts. The lifting cylinder is slidably arranged on the connecting plate through a cylinder seat and a guide rail, and is driven and connected to the shift cylinder to drive the gripper cylinder and the gripper block to lift and lower, and put the parts into or take them out of the pallet. The gripper cylinder is a conventional finger cylinder, and its fingers are connected to the gripper block through an indexing pin, etc., and the opposite sides of the gripper block are respectively provided with gripper grooves corresponding to the parts.

[0045] For example, see Figure 7 As shown, a support block 56 corresponding to the material moving device 5 is provided under the chain 21, and a positioning seat 57 and a positioning block 58 corresponding to the pallet 23 are provided on both sides of the support block 56 respectively. The positioning block 58 is slidably set on the workbench through a positioning cylinder 59, and a U-shaped positioning groove is opened on the side of the positioning block 58 close to the pallet.

[0046] In this technical solution, the support block is made of self-lubricating nylon blocks, etc., fixed to the side of the positioning seat, and a through groove corresponding to the chain is recessed on the top, which does not interfere with the free operation of the chain. When the lifting cylinder pushes the clamping cylinder down, it provides support for the chain. The positioning seat and the positioning block are respectively arranged on both sides of the pallet at the corresponding position. The support block is fixed to the workbench. When the material moving device loads or takes materials, the positioning cylinder drives the positioning block to abut against the positioning seat, and the U-shaped positioning groove limits the pallet to improve the accuracy of loading and taking materials.

[0047] In summary, the automatic circulation oven has a compact structure, and the chain serpentinely rotates in the baking chamber to reduce the volume of the box, thereby reducing the occupied space, and the cooling chamber accelerates the cooling of the rotor to improve production efficiency.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0049] The above is only a specific implementation of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
