[0046] See also Figures 1 to 11 As shown, this embodiment discloses a partitioned modular drying device, which includes:

[0047] The furnace body 30 includes an outer shell 301, an upper furnace body 302 and a lower furnace body 303. The upper furnace body 302 and the lower furnace body 303 are fixedly connected to the inner part of the outer shell 301, and the upper furnace body 302 is placed above the lower furnace body 303;

[0048] A feeding mechanism, which is drivingly connected to the upper furnace body 302 and is used to transfer external materials into the upper furnace cavity of the upper furnace body;

[0049] The reflux mechanism is transmission-connected to the lower furnace body 303 and is arranged parallel to the feeding mechanism and is placed below the feeding mechanism. The feeding end of the reflux mechanism and the discharging end of the reflux mechanism are respectively arranged corresponding to the discharging end and the feeding end of the feeding mechanism. The reflux mechanism is used to transfer the jig from the discharging end side of the feeding mechanism to the feeding end side of the feeding mechanism.

[0050] Two material blocking mechanisms 40 are respectively connected to the discharge end of the feed mechanism and the discharge end of the reflux mechanism, and the material blocking mechanisms 40 include: a first blocking column 401 and a second blocking column 402; the first blocking columns 401 of the two material blocking mechanisms 40 are respectively used to limit the movement of the fixtures closest to the discharge ends of the feed mechanism and the reflux mechanism, and the second blocking columns 402 of the two material blocking mechanisms 40 are respectively used to limit the movement of other fixtures on the feed mechanism and the reflux mechanism;

[0051] A plurality of modular heating mechanisms 50 are connected to the upper furnace body 302 . The plurality of modular heating mechanisms 50 are closely arranged transversely from the feeding end of the feeding mechanism to the discharging end of the feeding mechanism and are placed on both sides of the feeding mechanism.

[0052] Please see attached Fig.11 The modular heating mechanism 50 includes a plurality of heating units 503 , each of which includes a heating plate 5031 and an elastic member connected to the back of each heating plate 5031 .

[0053] Specifically, the modular heating mechanism 50 further includes: a connecting plate 5034 and a driving unit 5033 for driving the connecting plate 5034, one end of the elastic member is connected to the back of the heating plate 5031, and the other end is connected to the driving end of the driving unit 5033. In this example, a limiting cylinder 5032 is further provided on the front plate surface of the connecting plate 5034, and the elastic member is arranged in the cylinder cavity of the limiting cylinder 5032 to prevent the elastic member from deflecting. In this embodiment, the driving unit 5033 can select a power module such as a servo motor or a cylinder, an electric cylinder, etc., and several elastic members are connected to the same larger connecting plate 5034. At least one elastic member is provided on the back of each heating plate 5031. When the material is contacted and dried, the driving unit 5033 first drives the connecting plate 5034 to extend or rise. When the connecting plate is extended or raised to a set position, the heating plates 5031 at different positions have different compression strokes under the support of the elastic members on their backs, so as to contact different concave-convex structures or different drying temperature zones on the surface of the material. After drying is completed, the driving unit 5033 drives the connecting plate 5034 to return to its position so that the material can be sent out.

[0054] It should be noted that, in the present embodiment, the modular heating mechanism 50 is symmetrically arranged on both sides of the furnace body. In other embodiments, the modular heating mechanism 50 can also be symmetrically arranged on the upper and lower sides of the furnace body. Of course, the modular heating mechanism 50 is still only arranged on one side of the furnace body.

[0055] The modular heating mechanism 50 is attached to the feeding mechanism, the number of modular heating mechanisms 50 is related to the length of the feeding mechanism, and the modular heating mechanism 50 is arranged on both sides of the feeding mechanism. By adjusting the length of the feeding mechanism, it can be ensured that the partitioned modular drying equipment can accommodate a larger number of jigs, and it can also ensure that the materials on the jigs can be heated evenly.

[0056] The transmission directions of the feeding mechanism and the reflux mechanism are opposite. The reflux mechanism can transfer the jigs dried on the upper furnace body to the side of the furnace body 30 close to the feeding end of the feeding mechanism, saving the time of transporting the jigs separately and improving the production efficiency. At the same time, the first stop column 401 and the second stop column 402 realize the sequential recovery of the jigs on the feeding mechanism and enable the jigs to be closely arranged on the feeding mechanism, which is convenient for the control of the jigs and improves the transmission efficiency. Before the partitioned modular drying equipment works, the jig is stored in the reflux mechanism, and the reflux mechanism starts to transport the jig to the outlet of the reflux mechanism, and the material to be dried (the material can be auto parts, circuit boards or wafers, etc.) is loaded into the above jig. After the material is loaded, it is sent to the feeding mechanism by robots, manual labor, lifting racks or other means. All jigs enter the feeding mechanism in turn through the above process, and at this time the first blocking column 401 is in an ascending state, and the second blocking column 402 is in a descending state. The first jig that enters the feeding mechanism cannot move forward after contacting the first blocking column 401, and the subsequent jigs are blocked by the jigs that cannot move forward in front in turn, so that the jigs are closely fitted to each other, meeting the preset drying requirements, avoiding the inability of the feeding mechanism to store the specified number of jigs due to inconsistent spacing, and all jigs are closely arranged behind the feeding mechanism , the modular heating mechanism 50 starts heating, and the partitioned modular drying equipment starts drying; the modular heating mechanism 50 stops heating, and after the partitioned modular drying equipment completes the drying work, the jig is taken out from the discharge end of the feed mechanism by a robot, manual labor, a lifting frame or other means, and after the dried material is taken out of the jig, the empty jig is transferred to the reflux mechanism, and the reflux mechanism separates the jig closest to the discharge end of the reflux mechanism from other jigs on the reflux mechanism through the material blocking mechanism 40, and transports them to the outside of the discharge end of the reflux mechanism, at this time, the jig is directly loaded, and in the process of recycling other jigs, the loaded jig is simultaneously transferred to the feed mechanism by a robot, manual labor, a lifting frame or other means, repeating the work before the partitioned modular drying equipment works, saving the time of performing multiple processes separately.

[0057] In one embodiment, the modular heating mechanism 50 includes: a plurality of electric heating wires 501, an air blast assembly 502 and a heating unit 503, wherein the heating unit 503 is fixedly connected to the upper furnace body 302, the air blast assembly 502 is placed between the outer shell 301 and the heating unit 503, and the plurality of electric heating wires 501 are distributed around the air blast assembly 502, and the air blast assembly 502 is used to transfer the heat generated by the electric heating wires 501 to the feeding mechanism. The heating unit 503 separates the electric heating wires 501 and the air blast assembly 502 from the feeding mechanism, which can prevent the electric heating wires 501 and the air blast assembly 502 from being damaged by the impact of the jig, and can also prevent some materials from contacting the local high temperature around the electric heating wires 501, so that all materials in the upper furnace body 302 are heated unevenly.

[0058] Specifically, a plurality of gaps are provided between adjacent heating units 503 to facilitate the air blowing assembly 502 to deliver hot air to the feeding mechanism through the gaps.

[0059] Specifically, the air blowing assembly 502 includes: a wind wheel 5021 and a wind wheel driving assembly 5022, and the wind wheel driving assembly 5022 is used to drive the wind wheel 5021 to rotate.

The jig transported by the feeding mechanism is a jig filled with materials. The weight of the jig itself plus the weight of the materials places high requirements on the first synchronous wheel groups 102, and in order to ensure the transportation efficiency, this embodiment uses four groups of first synchronous wheel groups 102 to transport the jig, and at the same time can increase the number of jigs carried by the feeding mechanism. In this embodiment, the feeding mechanism can accommodate at least 9 jigs, all jigs are closely arranged, and each jig can load at least 63 materials, so that the partitioned modular drying equipment has high output and high efficiency in a single operation.

It is understood that in other embodiments, a synchronous belt, a screw rod or other transmission components can be used to replace the first chain belt 1021. Preferably, the first chain belt 1021 is a double-speed chain, which has the advantages of high efficiency, strong flexibility, and strong scalability, can improve the efficiency of transmission, and can ensure the stable transmission of the feeding mechanism.

In this embodiment, the first driving member 1011 is a motor, and in other embodiments, a rotary cylinder or other driving member can be used instead of the motor.

[0063] Preferably, the first driving assembly 101 further includes: a first sub-synchronous wheel set 1013, through which the first driving member 1011 is connected to the first transmission shaft 1012, and the first sub-synchronous wheel set 1013 includes: a first driving wheel 10131, a plurality of first driven wheels 10132, and a first sub-chain belt 10133; one of the first driven wheels 10132 is fixedly connected to one end of the first transmission shaft 1012, the first driving wheel 10131 is fixedly connected to the output shaft of the first driving member 1011, and the first sub-chain belt 10133 is sleeved between the first driving wheel 10131 and all the first driven wheels 10132.

The first sub-synchronous wheel set 1013 has a buffering effect during the transmission process, can protect the first driving member 1011, and can adjust the position of the first driving member 1011. The first driving member 1011 is arranged below the first synchronous wheel set 102 to provide a larger space for the transmission of the fixture. It can be understood that the first sub-chain belt 10133 can be set as a whole section or multiple sections.

It can be understood that in other embodiments, a synchronous belt, a screw rod or other transmission components can be used to replace the second chain belt 2021. Preferably, the second chain belt 2021 is a double-speed chain, which has the advantages of high efficiency, strong flexibility, and strong scalability, can improve the efficiency of transmission, and can ensure stable transmission of the feeding mechanism.

The first blocking column 401 and the second blocking column 402 are linked by the connecting rod 403. When the blocking driving component 406 drives the first blocking column 401 to descend, the second blocking column 402 can rise. Through the transmission of the feeding mechanism or the reflux mechanism, the jig between the first blocking column 401 and the second blocking column 402 can be sent out of the furnace body 30, thereby realizing convenient control of the blocking mechanism 40, saving the number of driving components and reducing the cost of production and maintenance.

In the initial state, the material blocking driving assembly 406 does not work, and the return spring 411 lifts the guide plate 409 that originally sank due to its own gravity, so the first blocking column 401 remains in an ascending state. When the material blocking driving assembly 406 is working, the cam 410 is pushed from the edge of the guide plate 409 toward the direction where the guide plate 409 is close to the first blocking column 401, so that the cam 410 penetrates between the bottom plate 407 and the guide plate 409. As the cam 410 is continuously squeezed in, the guide plate 409 continuously descends until the first blocking column 401 descends and drives the second blocking column 402 to rise through the connecting rod 403. In this embodiment, the material blocking driving assembly 406 is a cylinder. When the cylinder is extended, the guide plate 409 is pressed down by the cam 410, the return spring 411 is stretched, and the first blocking column 401 descends. When the cylinder is retracted, the guide plate 409 is retracted under the elastic action of the return spring 411, the first blocking column 401 resumes the ascending state, and the second blocking column 402 is thus descended.

The first block 412 and the second block 413 can increase the contact surface between the material blocking mechanism 40 and the fixture, so as to facilitate the blocking of the fixture from moving forward, and can limit the first blocking column 401 and the second blocking column 402 from separating from the support plate 405 when they descend, so as to facilitate the lifting and lowering control of the first blocking column 401 and the second blocking column 402.

[0077] Preferably, the material blocking mechanism 40 further includes: a guide post 408, the guide post 408 is movably connected to the bottom plate 407, and the bottom end of the guide post 408 is fixedly connected to the end of the guide plate 409 close to the cam.

The two upper door panels correspond to the feeding end and the discharging end of the feeding mechanism, and the upper door panels can move up and down relative to the upper furnace body 302 to realize the opening and closing of the upper furnace body 302, so that the jig for loading materials enters the feeding mechanism when the upper furnace body 302 is opened. A fan 60 is also provided on the side cover 3012, and the heat dissipation holes on the fan 60 and the side cover 3012 are convenient for heat dissipation of the wind wheel drive component 5022.

[0079] Specifically, the side cover 3012 is also provided with a side door panel 30121 , which facilitates the staff to inspect and repair the modular heating mechanism 50 .

[0080] Preferably, a heat insulating layer 304 is provided between the top cover 3011 and the side cover 3012 and the upper furnace body 302. When the modular heating mechanism 50 is working, the heat insulating layer 304 can reduce the temperature loss in the upper furnace body 302 and maintain a constant temperature; at the same time, it plays a role of temperature buffer, so that the staff are not easily scalded by the top cover 3011 and the side cover 3012.

[0083] The partitioned modular drying equipment of this embodiment designs the heating unit in contact with the material into a plurality of elastically liftable heating plate structures, which can not only make the heating plates abut against each other according to the concave and convex shapes of the material surface, but also can independently control the temperature of each heating plate, thereby improving the drying efficiency and quality. In addition, the equipment also realizes the circular transmission of the jig by setting a feeding mechanism and a reflux mechanism, saving the handling time of the jig and improving the efficiency of production; the number of modular heating mechanisms is related to the length of the feeding mechanism, and the modular heating mechanisms are arranged on both sides of the feeding mechanism.
