[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0031] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0032] like Figures 1 to 4 As shown, the present invention provides a cooling device for an annealing device, which can be used to cool components in the annealing device. The annealing device includes a protective cover 1, a blowing device (not shown) and a first exhaust device 2.

[0033] Reference Figure 1 The protective cover 1 can be provided to cover the components of the annealing device. The protective cover 1 can be used to protect the components and prevent external pollutants from contacting the components and thus affecting the operation of the components. The protective cover 1 can be provided with a through blowing port 11. In addition, the protective cover 1 can also be provided with a through exhaust port 12. The blowing port 11 and the exhaust port 12 can respectively connect the outside world with the inside of the protective cover 1. The blowing port 11 and the exhaust port 12 can be provided on the same side of the protective cover 1. For example, the exhaust port 12 and the air outlet can pass through different positions of the same side wall of the protective cover 1.

[0034] The blowing port 11 of the protective cover 1 can be connected to a blowing device so that the blowing device can blow air into the protective cover 1 through the blowing port 11. When the annealing device is working, the heat generated by the annealing chamber 200 in the annealing device may overflow and be transferred to the surrounding components of the annealing device, and the components may also generate heat during operation, thereby causing the temperature inside the protective cover 1 and the temperature of the components in the annealing device to gradually increase. Blowing air into the protective cover 1 through the blowing device can supply low-temperature or normal-temperature gas into the protective cover 1, and the low-temperature or normal-temperature gas can absorb the heat in the protective cover 1 to cool the components in the protective cover 1; in addition, blowing air into the protective cover 1 through the blowing device can also accelerate the air flow rate around the components, enhance the cooling effect on the components, prevent the temperature of the components from being too high, and ensure the stable operation of the components.

[0035] Reference Figure 1 The air outlet 11 of the protective cover 1 may be a through hole and no other components may be provided in the air outlet 11. The air blowing device may be directly or indirectly connected to the air outlet 11 through a connecting pipe. Alternatively, refer to Figure 2The blowing port 11 of the protective cover 1 may be provided with a blowing interface 111, the blowing interface 111 is sealedly connected to the wall forming the blowing port 11, and a blowing flow channel connected to the blowing port 11 is formed in the blowing interface 111. A portion of the blowing interface 111 may protrude from the protective cover 1. A blowing device may be connected to the portion of the blowing interface 111 protruding from the protective cover 1, so that the blowing device can be connected to the blowing port 11 through the blowing flow channel of the blowing interface 111, which facilitates the connection operation of the blowing device and the blowing port 11. The blowing device may specifically be a CDA (clean dry air purge) blowing device, which is used to blow clean and dry air into the protective cover 1, and the blowing interface 111 may specifically be a CDA blowing interface.

[0036] To facilitate the blowing device to control the on / off flow of air into the protective cover 1, a control valve may be provided between the blowing device and the air outlet 11. For example, the blowing device may be connected to the air outlet 11 or the air interface 111 via a connecting pipe, and the control valve may be provided on the connecting pipe. The control valve is used to open or close the connecting pipe to control the on / off flow of air between the blowing device and the air outlet 11, thereby controlling the on / off flow of air into the protective cover 1 by the blowing device. The control valve may specifically be a solenoid valve.

[0037] The air exhaust port 12 of the protective cover 1 can be used to connect with a second air exhaust device (not shown) so that the second air exhaust device can extract the internal gas of the protective cover 1 through the air exhaust port 12. The second air exhaust device and the blowing device can operate simultaneously, the blowing device is used to blow air into the protective cover 1, and the second air exhaust device is used to exhaust the protective cover 1 so that the gas in the protective cover 1 and the external gas flow in a circular manner, thereby continuously supplying fresh air to the protective cover 1. The fresh air can be discharged from the protective cover 1 after absorbing the heat in the protective cover 1, effectively cooling the components in the protective cover 1 and ensuring the stable operation of the components. The fresh air entering the protective cover 1 can be the clean and dry air blown in by the blowing device, and the mixed gas formed by the fresh air after absorbing heat and the original gas in the protective cover 1 can be extracted from the protective cover 1 by the second air exhaust device. The second air exhaust device can be an exhaust device such as an air pump.

[0038] The protective cover 1 may be provided with an exhaust pipe 13 extending toward the outside, and an opening where the exhaust pipe 13 communicates with the outside may form an exhaust port 12. By forming the exhaust port 12 with the exhaust pipe 13 extending toward the outside, a second exhaust device in the outside can be connected to the exhaust pipe 13 to complete the connection between the second exhaust device and the exhaust port 12, thereby facilitating the connection operation between the second exhaust device and the exhaust port 12.

[0039] The components located in the protective cover 1 may not be independently operated components, and the components need to be connected to other external components through pipes or lines. For example, when the component is a cylinder, the component needs to be connected to the gas supply device through a gas pipeline so that the component can operate normally. In order to facilitate the connection between the components in the protective cover 1 and other external components, the protective cover 1 is also provided with a connection port 14. The connection port 14 can pass through the protective cover 1 so that the components located in the protective cover 1 can be connected to other external components through the connection port 14. Among them, a connector 141 is preferably provided in the connection port 14, and a connecting pipeline communicating with the connection port 14 is formed in the connector 141, and a part of the connector 141 can protrude from the protective cover 1 to facilitate connection with other external components, so that other external components can be connected to the components in the protective cover 1 through the connector 141. When the component is a cylinder, the connector 141 can be a cylinder pipe port; when the component is other components, the connector 141 can be correspondingly provided as other interfaces or other circuit structures.

[0040] The connection port 14 of the protective cover 1 can be located on a different side from the air exhaust port 12 and the air blowing port 11. For example, the air exhaust port 12 and the air blowing port 11 of the protective cover 1 are located on the same side of the protective cover 1, and the connection port 14 of the protective cover 1 is located on the bottom surface or the top surface of the protective cover 1. The protective cover 1 can be provided with one or more connection ports 14, and the number of connection ports 14 can be adjusted according to the number of interfaces required by the components located in the protective cover 1. When the components in the protective cover 1 can operate independently or be connected to external components through wireless connection methods such as signal connection, and the components located in the protective cover 1 do not need to be connected to external components using pipes or lines, the protective cover 1 may not be provided with the connection port 14 to prevent external pollutants from entering the interior of the protective cover 1 through the connection port 14, thereby ensuring the protective effect of the protective cover 1 on the components.

[0041] Reference Figure 5The first exhaust device 2 is arranged at the top of the annealing device, and the first exhaust device 2 can be connected to the inside of the annealing device and used to extract the gas in the annealing device. The hot gas formed by the heat overflowing from the annealing chamber 200 in the annealing device will flow upward due to its low density, thereby causing the hot gas in the annealing device to gather toward the top of the annealing device; by arranging the first exhaust device 2 at the top of the annealing device, the direction in which the first exhaust device 2 extracts the gas in the annealing device can coincide with or substantially coincide with the flow direction of the hot gas in the annealing device, and the first exhaust device 2 is arranged at the hot gas gathering point of the annealing device, thereby effectively extracting the hot gas in the annealing device and making the exhaust process of the first exhaust device 2 smoother. Among them, the first exhaust device 2 can be specifically arranged on the top plate 401 of the frame 400 of the annealing device. The first exhaust device 2 can be set to one or more. When the first exhaust device 2 is set to multiple, the multiple first exhaust devices 2 can be evenly distributed on the top of the annealing device. For example, two first exhaust devices 2 are provided, and the two first exhaust devices 2 are distributed on opposite sides of the top of the annealing device, and the two first exhaust devices 2 are symmetrically distributed relative to the center position of the top of the annealing device. The first exhaust device 2 can be an exhaust fan.

[0042] The first exhaust device 2 can be connected to an external exhaust component, for example, an external exhaust pipeline, so that the gas and heat extracted from the annealing device by the first exhaust device 2 can be discharged into the external exhaust component and then discharged into the atmosphere or other designated places through the exhaust component.

[0043] The present invention further provides an annealing device, which includes a frame 400 having a top plate 401, an annealing chamber 200, at least one component, and the above-mentioned cooling device for the annealing device.

[0044] The annealing device may be provided with multiple components, including at least motors, cylinders and other components. The annealing device may be provided with multiple protective covers 1 in the cooling device, and each protective cover 1 may be provided to cover one component. Figure 3 When components are mounted on the bottom plate 300 or arranged on one side of the bottom plate 300, the protective cover 1 corresponding to the component can be open at one end, and the protective cover 1 can be covered on the bottom plate 300 so that the bottom plate 300 blocks the opening of the protective cover 1, and the protective cover 1 and the bottom plate 300 together form a storage space for accommodating components. For example, components are arranged on one side of the bottom plate 300 of the annealing chamber 200, and the protective cover 1 and the bottom plate 300 together form a storage space for accommodating components. Alternatively, refer to Figure 1The protective cover 1 is a rectangular box with a hollow interior, forming a storage space for components. For example, when the protective cover 1 is placed over a component such as a motor or cylinder, the motor or cylinder's mounting plate cannot completely block the sides of the protective cover 1. The protective cover 1 forms a rectangular box and accommodates the motor or cylinder. Each protective cover 1 is provided with an air extraction port 12 and an air outlet 11.

[0045] The cooling device may include multiple blowing devices and multiple second exhaust devices, each of which is connected to the blowing port 11 of a protective cover 1 and is used to blow air into the protective cover 1, and each of which is connected to the exhaust port 12 of a protective cover 1 and is used to exhaust air from the protective cover 1. Alternatively, the cooling device may include only one blowing device and one second exhaust device, and one blowing device may be connected to the blowing ports 11 of multiple protective covers 1, so that one blowing device can blow air into multiple protective covers 1 at the same time; one second exhaust device may be connected to the exhaust ports 12 of multiple protective covers 1, so that one second exhaust device can exhaust air into multiple protective covers 1 at the same time.

[0046] Reference Figure 3 and Figure 4 To prevent heat from escaping from the annealing chamber 200, a heat shield 201 may be attached to at least a portion of the surface of the annealing chamber 200. The heat shield 201 is made of a heat-insulating material and may be attached to the surface of the upper cover of the annealing chamber 200 and the sides of the annealing chamber 200. By using the heat shield 201 to prevent heat from escaping from the annealing chamber 200, the effect of heat from escaping from the annealing chamber 200 on the temperature within the annealing device is reduced, thereby reducing the effect of heat from escaping from the annealing chamber 200 on the components. This effectively reduces the temperature of the components during annealing in the annealing device, ensuring stable operation of the components.
