Description

Technical Field

[0001] The invention relates to the field of vacuum drying furnaces, in particular to a fully automatic vacuum drying tunnel furnace with a coating transmission mechanism. Background Art

[0002] Vacuum baking uses the lower boiling point of water in a vacuum environment to quickly evaporate water at a lower temperature, effectively avoiding the denaturation or loss of materials that may be caused by high-temperature baking. Due to the lower boiling point, water evaporates faster, shortening the drying time (such as the moisture hidden between the electrode membranes of lithium batteries, which takes a long time to dry in traditional ovens). At the same time, it can prevent oxidation (vacuum environment can effectively prevent oxidation of materials), and is suitable for heat-sensitive materials (for some heat-sensitive materials such as lithium batteries, vacuum baking can provide milder drying conditions), so it can be widely used in: batteries, food, coatings and other fields. Vacuum baking uses the lower boiling point of water in a vacuum environment to quickly evaporate water at a lower temperature, effectively avoiding material denaturation or loss caused by high-temperature baking, and is more efficient and energy-saving. Currently, there are mainly two types of drying furnaces: single-body drying furnaces and tunnel drying furnaces. Single-body drying furnaces must be placed in a drying room, and the loading and unloading actions in the drying furnace are mainly completed by robots running on tracks; tunnel drying furnaces do not need to be completely in the drying plant, and the tunnel exit can be in the drying room. The entire process is mainly completed by transporting materials in the tunnel through clamps. After drying, materials are unloaded directly in the cooling room without the need for robots, while saving space in the drying room.

[0003] However, the existing tunnel drying furnace means that the door of the vacuum chamber has to be opened frequently when adding materials, which results in frequent vacuum extraction and release, and increased energy consumption. Summary of the invention

[0004] In view of the existing problems, the present invention provides a fully automatic vacuum drying tunnel furnace with a coating transmission mechanism, which can effectively solve the problems raised in the background technology when used in combination.

[0005] To solve the above problems, the present invention adopts the following technical solutions: A fully automatic vacuum drying tunnel furnace with a coating transmission mechanism comprises a drying tunnel furnace, the drying tunnel furnace comprising: a finished product storage bin, a hot drying processing bin, and a feeding bin, an upper partition plate is installed between the finished product storage bin and the hot drying processing bin, a lower partition plate is installed between the hot drying processing bin and the feeding bin, a limiting slide groove is provided on the lower surface of one end of the lower partition plate, a closed plug-in cover plate is installed below the limiting slide groove, a sealing slot is installed on the side surface of the drying tunnel furnace corresponding to the outer side of the closed plug-in cover plate, a hydraulic pushing mechanism is installed between the end of the closed plug-in cover plate located away from the sealing slot and the lower partition plate, a coating transmission mechanism is installed on the upper surface of the lower partition plate located inside the hot drying processing bin, a material preparation transmission track is installed below the lower partition plate located inside the feeding bin, the coating transmission mechanism comprises: a driving mechanism, a transmission chain, and a mounting bracket, a moving mechanism is arranged on the outer array of the transmission chain, a device placement pad mounting frame is installed on the upper end of the moving mechanism, and a supporting pad is installed on the outer side of the device placement pad mounting frame.

[0006] As a further solution of the present invention: an angle adjustment frame is installed at the lower end of the moving mechanism, a mounting clamping seat is installed between the angle adjustment frame and the transmission chain, and a waste collection box is arranged below the device placement pad mounting frame.

[0007] As a further solution of the present invention: a heating wire is installed on the inner wall of the hot drying processing chamber outside the coating transmission mechanism, and a thermal control mechanism is installed on the outer side of the drying tunnel furnace at a position corresponding to the heating wire.

[0008] As a further solution of the present invention: a vacuum tube is installed on the upper surface of the drying tunnel furnace, one end of the vacuum tube is located outside the drying tunnel furnace and a vacuum pump is installed, a main cabinet door is opened at one end of the hot drying processing warehouse below the vacuum pump, and a charging cabinet door is installed at one end of the charging warehouse below the main cabinet door.

[0009] As a further solution of the present invention: a sealing gasket is installed on the outer side wall of the closed plug-in cover plate corresponding to the inner side of the sealing slot, and a guide slider is installed between the closed plug-in cover plate and the limiting slide groove.

[0010] As a further solution of the present invention: the upper partition plate is provided with a through hole at one end away from the closed plug-in cover plate, and the moving mechanism is movably connected to the angle adjustment frame.

[0011] As a further solution of the present invention: mechanical arms are installed inside the finished product storage bin and the heat drying processing bin.

[0012] As a further solution of the present invention: a limit pin is installed between the mounting bracket and the transmission chain, and the waste collection box is fixedly connected to the mounting bracket.

[0013] As a further solution of the present invention: the thermal control mechanism is electrically connected to the heating wire.

[0014] As a further solution of the present invention: the vacuum tube is connected to the finished product storage bin, and the inner walls of the main cabinet door and the material adding cabinet door are both installed with sealing gaskets.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When in use, the lower partition plate and the upper partition plate divide the entire drying tunnel furnace into three parts. The lower partition plate can be used to select the connectivity of the three parts. When the lower partition plate is used to close the connectivity between the hot drying processing bin and the feeding bin, the finished product storage bin and the hot drying processing bin are evacuated to use the heating wire to perform heat drying on the components inside the hot drying processing bin. At the same time, the feeding cabinet door is opened to add materials to the inside of the preparation transmission track. When drying is required next time, the lower partition plate is disconnected and the vacuum leakage is smaller, reducing energy consumption.

[0016] 2. The driving mechanism as a whole drives the transmission chain to rotate. The rotating transmission chain drives the moving mechanism as a whole to move. At the same time, after the heating and drying treatment by the heating wire, the uniformity of heating and drying can be guaranteed. When the residual paint on the workpiece moves, it will fall into the waste collection box for collection, which is convenient for subsequent cleaning.

[0017] 3. The heating wire corresponds to the inside of the hot drying processing bin as a whole. After the drying process, according to the principle of heat transfer, the devices collected in the finished product storage bin will also maintain a higher temperature to use the residual heat to ensure the drying effect. At the same time, due to the higher strength of the outer surface of the dried devices, the placement interval can be reduced or even stacked inside the finished product storage bin. Therefore, the storage quantity inside the finished product storage bin can be guaranteed. Therefore, it is only necessary to take out the material once after multiple additions.

[0018] 4. When processing devices with high requirements for temperature control, a door panel that can be opened and closed can be set at the position of the through hole in the form of an internal feeding bin to control the passage adjustment between the finished product storage bin and the heat drying processing bin. Therefore, during processing, the passage between the finished product storage bin, the heat drying processing bin and the feeding bin can be changed to cope with the processing of different workpieces.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example, and the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0023] like Figure 1-6As shown, the present embodiment provides a fully automatic vacuum drying tunnel furnace with a coating transmission mechanism, including a drying tunnel furnace 1, the drying tunnel furnace 1 including: a finished product storage bin 101, a hot drying processing bin 102, and a feeding bin 103, an upper partition plate 110 is installed between the finished product storage bin 101 and the hot drying processing bin 102, a lower partition plate 104 is installed between the hot drying processing bin 102 and the feeding bin 103, a limiting slide groove 107 is provided on the lower surface of one end of the lower partition plate 104, a closed plug-in cover plate 105 is installed below the limiting slide groove 107, a guide slider is installed between the closed plug-in cover plate 105 and the limiting slide groove 107, and a side surface of the drying tunnel furnace 1 is installed corresponding to the outer side of the closed plug-in cover plate 105 There is a sealing slot 106, and a sealing gasket is installed on the outer wall of the closed plug-in cover plate 105 corresponding to the inner side of the sealing slot 106. A hydraulic pushing mechanism 108 is installed between the closed plug-in cover plate 105 at the end away from the sealing slot 106 and the lower partition plate 104. The upper partition plate 110 is located at the end away from the closed plug-in cover plate 105 and has a through hole. When processing devices with high temperature control requirements, a door panel that can be opened and closed can be set at the position of the through hole in the form of an internal feeding bin 103, so as to control the passage adjustment between the finished product storage bin 101 and the hot drying processing bin 102, so as to ensure that the finished product storage bin 101, the hot drying processing bin 102 and the feeding bin 103 are connected during processing. The passage between them can be changed to cope with the processing of different workpieces. A robotic arm 9 is installed inside the finished product storage bin 101 and the hot drying processing bin 102. The finished product storage bin 101 is provided with a cabinet door on the side away from the robotic arm 9. The upper surface of the lower partition plate 104 is located inside the hot drying processing bin 102 and is provided with a coating transmission mechanism 7. The lower surface of the lower partition plate 104 is located inside the hot drying processing bin 102 and is provided with a material preparation transmission track 8. The coating transmission mechanism 7 includes: a driving mechanism 701, a transmission chain 702, and a mounting bracket 703. The outer array of the transmission chain 702 is provided with a moving mechanism 704. The upper end of the moving mechanism 704 is provided with a device placement pad mounting frame 705. The device placement A supporting pad block 707 is installed on the outer side of the pad mounting frame 705. When in use, the lower partition plate 104 and the upper partition plate 110 divide the entire drying tunnel furnace 1 into three parts. The lower partition plate 104 can be used to select the connectivity of the three parts. When the lower partition plate 104 is used to close the connectivity between the hot drying processing bin 102 and the feeding bin 103, the finished product storage bin 101 and the hot drying processing bin 102 are evacuated to perform hot drying treatment on the components inside the hot drying processing bin 102. At the same time, the feeding cabinet door 6 is opened to add materials to the inside of the preparation transmission track 8. When drying treatment is needed next time, the vacuum leakage degree will be smaller after the lower partition plate 104 is disconnected, thereby reducing energy consumption.

[0024] like Figure 2-6As shown, in this embodiment, an angle adjustment frame 708 is installed at the lower end of the moving mechanism 704, and the moving mechanism 704 is movably connected to the angle adjustment frame 708. A mounting clamping seat 709 is installed between the angle adjustment frame 708 and the transmission chain 702, and a limit pin is installed between the mounting clamping seat 709 and the transmission chain 702. By controlling the moving mechanism 704 to use the installation interval on the outer side of the transmission chain 702, the amount of drying at one time can be controlled. A waste collection box 706 is arranged below the device placement pad mounting frame 705, and the waste collection box 706 is fixedly connected to the mounting bracket 703. The outer side of the coating transmission mechanism 7 is located on the inner side wall of the hot drying processing chamber 102 and a heating wire 109 is installed. The outer side of the drying tunnel furnace 1 is installed at a position corresponding to the heating wire 109. The thermal control mechanism 4 is electrically connected to the heating wire 109. The heating wire 109 corresponds to the inside of the hot drying processing chamber 102 as a whole. After the drying process, according to the heat transfer The principle is that the devices collected in the finished product storage bin 101 will also maintain a relatively high temperature to utilize the waste heat to ensure the drying effect. At the same time, due to the high strength of the outer surface of the dried devices, the placement interval can be reduced or even stacked inside the finished product storage bin 101, so the storage quantity inside the finished product storage bin 101 can be guaranteed. Therefore, it is only necessary to take out the materials once after multiple additions. A vacuum tube 3 is installed on the upper surface of the drying tunnel furnace 1. The vacuum tube 3 is connected to the finished product storage bin 101. One end of the vacuum tube 3 is located on the outside of the drying tunnel furnace 1 and a vacuum pump 2 is installed. A main cabinet door 5 is provided at one end of the hot drying processing bin 102 below the vacuum pump 2. A charging cabinet door 6 is installed at one end of the charging bin 103 below the main cabinet door 5. The inner side walls of the main cabinet door 5 and the charging cabinet door 6 are both installed with sealing gaskets. The main cabinet door 5 is provided for placing and adding devices to be processed into the interior of 102 after each retrieval is completed.

[0025] The working principle of the present invention is: before use, after placing the coated device as a whole on the upper position of the device placement pad mounting frame 705, and then placing the device to be processed on the upper position of the material preparation transmission track 8, after the main cabinet door 5 and the feeding cabinet door 6 are tightly closed as a whole, the vacuum pump 2 is started to evacuate the interior of the finished product storage bin 101, the hot drying processing bin 102, and the feeding bin 103 through the vacuum pipe 3, and then the driving mechanism 701 is used to drive the transmission chain 702 to rotate as a whole. The rotating transmission chain 702 drives the moving mechanism 704 to move as a whole, and after the heating of the heating wire 109 is dried, the residual paint on the workpiece will fall into the waste collection box 706 for accumulation during movement. After the rotation and drying is completed, the mechanical arm 9 at the upper position of the finished product storage bin 101 is started to clamp the workpiece dried by the coating transmission mechanism 7 upwards After that, the processed devices are stored in the finished product storage bin 101, and then the mechanical arm 9 under the lower partition plate 104 is started at the same time to clamp the devices to be processed on the material preparation transmission track 8 inside the material preparation bin 103 to the upper position of the coating transmission mechanism 7. Therefore, the reciprocating movement can reduce the number of openings. After the consumption of the tools to be processed on the material preparation transmission track 8 is completed, the hydraulic pushing mechanism 108 is started to push the closed plug-in cover plate 105 to move inside the limiting slide groove 107, and the closed plug-in cover plate 105 is completely sealed inside the sealing slot 106, and the connection between the hot drying processing bin 102 and the material filling bin 103 is sealed. After opening the material filling cabinet door 6, after adding the workpiece to the material preparation transmission track 8 again, the sealing effect of the closed plug-in cover plate 105 is disconnected, and then the vacuum pump 2 is used to evacuate the air, which can reduce the vacuuming amount and greatly reduce the vacuuming amount and the number of vacuuming times.
