[0034] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure.
[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.
[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0037] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0038] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0039] According to one embodiment of the present disclosure, a dust-free processing device is provided, comprising a housing, a fan filter unit, and a device body. The fan filter unit is mounted on the housing and is used to deliver dust-free air into the housing so as to maintain a dust-free environment within the housing. The device body is housed within the housing so that the device body performs processing operations in the dust-free environment within the housing. Optionally, the device body may be a pole piece slitting machine or a winding machine. Of course, in other embodiments, the device body may also be other machines that need to perform processing operations in a dust-free environment, which is not limited here.
[0040] Referring to Figures 1 to 3, in an embodiment of the present disclosure, the fan filter unit includes a guide assembly 10, a filter box 20 and a fan box 30. The guide assembly 10 is mounted on the housing, and the filter box 20 is movably connected to the guide assembly 10. The fan box 30 is located on the side of the filter box 20 facing away from the guide assembly 10, and is operably connected to or separated from the filter box 20. When the fan box 30 is separated from the filter box 20, under the guidance of the guide assembly 10, the filter box 20 can exit or enter the space between the guide assembly 10 and the fan box 30. It should be noted that the separation of the fan box 30 and the filter box 20 can refer to the release of the connection between the two, or it can refer to the switching of the two from a contact state to a non-contact state, as long as it is convenient for the filter box 20 to enter or exit the space between the guide assembly 10 and the fan box 30, and is not limited here.
[0041] In this way, when the filter box 20 needs to be replaced, first separate the fan box 30 from the filter box 20; then pull the filter box 20 out from the space between the guide assembly 10 and the fan box 30; and then push the replaced filter box 20 into the space between the guide assembly 10 and the fan box 30. Finally, connect the fan box 30 to the replaced filter box 20, and the replacement of the filter box 20 is completed. Compared with the prior art, in the present disclosure, when replacing the filter box 20, there is no need to remove the entire fan filter unit from the outer casing. It is only necessary to pull the filter box 20 to be replaced from between the guide assembly 10 and the fan box 30, and push the replaced filter box 20 into the space between the guide assembly 10 and the fan box 30. This greatly reduces the workload of the operator, eliminates the need for multiple people to cooperate in the operation, greatly shortens the time required to replace the filter box 20, and is conducive to improving production efficiency.
[0042] Furthermore, the housing has an air inlet connected to the filter box 20. The airflow delivered by the fan box 30 is filtered by the filter box 20 before entering the interior of the housing through the air inlet. In other words, the fan box 30 blows air toward the filter box 20, which filters the airflow. The filtered airflow then enters the interior of the housing through the air inlet, maintaining a dust-free environment inside the housing.
[0043] In an embodiment of the present disclosure, the fan filter unit further includes a first support base 40. The first support base 40 is fixedly connected to the housing so that the first support base 40 is fixed relative to the guide assembly 10. The fan box 30 has a first end a1 and a second end a2 opposite the first end a1. The first end a1 of the fan box 30 is rotatably connected to the first support base 40, allowing the fan box 30 to rotate relative to the first support base 40. The process of the fan box 30 rotating relative to the first support base 40 includes a first position (see Figure 1 or Figure 2) and a second position (see Figure 3). When the fan box 30 rotates relative to the first support base 40 to the first position (see Figure 1 or Figure 2), the fan box 30 is supported on the filter box 20. When the fan box 30 rotates relative to the first support base 40 to the second position (see Figure 3), the fan box 30 is separated from the filter box 20, so that the filter box 20 can be smoothly pulled out of the space between the fan box 30 and the guide assembly 10.
[0044] In this way, when the filter box 20 needs to be replaced, the fan box 30 is first rotated from the first position to the second position so that the fan box 30 is separated from the filter box 20; then the filter box 20 is pulled out from the space between the guide assembly 10 and the fan box 30 (i.e., the filter box 20 slides out of the space between the guide assembly 10 and the fan box 30 along the guide assembly 10); then, the replaced filter box 20 is pushed into the space between the guide assembly 10 and the fan box 30 (i.e., the filter box 20 slides into the space between the guide assembly 10 and the fan box 30 along the guide assembly 10); finally, the fan box 30 is rotated from the second position to the first position so that the fan box 30 is supported on the filter box 20. At this time, the filter box 20 is supported on the guide assembly 10, and the fan box 30 is supported on the filter box 20 and the first support base 40, thereby achieving the fixation of the filter box 20 and the fan box 30 relative to the housing.
[0045] Optionally, the first end a1 of the fan box 30 is mounted on the first support base 40 via a hinge 41, so that the fan box 30 can rotate relative to the first support base 40. Of course, the first end a1 of the fan box 30 and the first support base 40 can also adopt other rotational connection methods, such as hinged connection, which is not limited here.
[0046] Furthermore, a locking member 21 is provided on the filter box 20, and a locking mating member 32 is provided on the fan box 30. When the fan box 30 is rotated to the first position relative to the first support base 40, the fan box 30 is supported on the filter box 20, and the locking member 21 on the filter box 20 is operably locked with the locking mating member 32 on the fan box 30, thereby locking and fixing the fan box 30 to the filter box 20. Optionally, the locking member 21 can be a hasp, and the locking mating member 32 can be a hook that can be locked with the hasp.
[0047] It should be noted that, in other embodiments, the locking member 21 can also be installed on the fan box 30, and the locking fitting 32 can be installed on the filter box 20, as long as the fan box 30 and the filter box 20 can be locked, which is not limited here.
[0048] In the embodiment of the present disclosure, the fan filter unit further includes a support assembly 50 for supporting the fan box 30 in the second position. Thus, when the fan box 30 rotates from the first position to the second position relative to the first support base 40, the support assembly 50 supports the fan box 30, maintaining the fan box 30 in the second position, thereby facilitating replacement of the filter box 20 by an operator.
[0049] Specifically in the embodiment, the support assembly 50 includes a second support seat 51 and a support member 53. The second support seat 51 is fixedly connected to the outer shell, so that the second support seat 51 is relatively fixed to the guide assembly 10. One end of the support member 53 is rotatably connected to the second support seat 51. When the fan box 30 is rotated to the second position relative to the first support seat 40, the support member 53 is rotated relative to the second support seat 51 to a position capable of supporting the fan box 30, so that the fan box 30 remains in the second position. Optionally, one end of the support member 53 is mounted on the second support seat 51 through a rotating shaft 55. Of course, in other embodiments, the support member 53 can also be rotatably connected to the second support seat 51 in other ways, as long as the support member 53 can be rotatable, which is not limited here.
[0050] Furthermore, the first end a1 of the fan box 30 is rotatably connected to the first support base 40. When the fan box 30 rotates to the second position relative to the first support base 40, the second end a2 of the fan box 30 can be supported by the support member 53, so that the fan box 30 remains in the second position.
[0051] Furthermore, the support member 53 has a limiting groove 531, and a support pin 33 is fixedly connected to the fan box 30. When the fan box 30 is rotated to the second position relative to the first support base 40, the support pin 33 on the fan box 30 can be supported in the limiting groove 531 on the support member 53, so that the support member 53 supports the fan box 30 and ensures that the fan box 30 remains in the second position. When the fan box 30 is no longer needed to be supported, the fan box 30 is first lifted and the support member 53 is rotated so that the support pin 33 is withdrawn from the limiting groove 531, that is, the support member 53 is separated from the support pin 33; then, the fan box 30 is rotated from the second position to the first position. At this time, the fan box 30 is supported on the filter box 20, and the fan box 30 and the filter box 20 can be locked and fixed by the locking member 21 and the locking fitting 32.
[0052] Optionally, the support member 53 may be a support rod. When supporting the fan box 30, the support rod is rotated until the support pin 33 enters the limiting groove 531. Of course, in other embodiments, the support member 53 may also be a pneumatic cylinder, an electric cylinder, or a nitrogen spring, thereby providing more stable and reliable support for the fan box 30.
[0053] Specifically, in this embodiment, the support assembly 50 includes two support assemblies 50, which are arranged at an interval from each other, and the second end a2 of the fan box 30 is located between the two support assemblies 50. In this way, when the fan box 30 rotates to the second position relative to the first support base 40, the two support assemblies 50 can simultaneously support the second end a2 of the fan box 30, making the support for the fan box 30 more stable and preventing the fan box 30 from falling from the second position due to its own gravity.
[0054] Specifically, in this embodiment, a handle 31 is provided at the second end a2 of the fan box 30, so that an operator can lift the fan box 30 by means of the handle 31, thereby rotating the fan box 30 relative to the first support base 40 to the first position or the second position. Thus, the provision of the handle 31 saves the operator's effort and greatly reduces the operator's workload.
[0055] Furthermore, the filter box 20 has a third end a3 and a fourth end a4 opposite the third end a3. When the filter box 20 is located in the space between the guide assembly 10 and the fan box 30, the third end a3 of the filter box 20 is positioned toward the first support base 40, and the fourth end a4 of the filter box 20 is positioned between the second support bases 51 of the two support assemblies 50. In other words, when the filter box 20 is located in the space between the guide assembly 10 and the fan box 30, the third end a3 of the filter box 20 is positioned near the first end a1 of the fan box 30, and the fourth end a4 of the filter box 20 is positioned near the second end a2 of the fan box 30.
[0056] A handle 22 is provided at the fourth end a4 of the filter box 20, so that the operator can use the handle 22 to pull the filter box 20 out of the space between the guide assembly 10 and the fan box 30, or push the filter box 20 into the space between the guide assembly 10 and the fan box 30. In this way, the provision of the handle 22 saves the operator's effort and greatly reduces the operator's workload.
[0057] In the embodiment of the present disclosure, the guide assembly 10 includes a first guide rail 11 and a second guide rail 12, both fixedly connected to the housing. The first and second guide rails 11, 12 are arranged parallel to and opposite each other. The filter box 20 is supported on the first and second guide rails 11, 12 and is capable of sliding along the longitudinal extension of the first and second guide rails 11, 12 under the action of an external force. As the filter box 20 slides along the first and second guide rails 11, 12, it can enter or exit the space between the guide assembly 10 and the fan box 30, thereby enabling replacement of the filter box 20.
[0058] Furthermore, one end of the first guide rail 11 and the second guide rail 12 are close to the first support base 40, and the other ends of the first guide rail 11 and the second guide rail 12 are close to the second support base 51. In this way, when the filter box 20 is pulled or pushed, the filter box 20 slides along the first guide rail 11 and the second guide rail 12 until it enters or exits the space between the guide assembly 10 and the fan box 30.
[0059] Furthermore, the guide assembly 10 also includes a first baffle 13 and a second baffle 14. The first baffle 13 is fixedly disposed at one end of the first guide rail 11 and the second guide rail 12 facing the first support seat 40 to prevent the filter box 20 from exiting the space between the guide assembly 10 and the fan box 30 in the direction toward the first support seat 40. The second baffle 14 is fixedly disposed at one end of the first guide rail 11 and the second guide rail 12 facing the second support seat 51 to prevent the filter box 20 from exiting the space between the guide assembly 10 and the fan box 30 in the direction toward the second support seat 51. In this way, when the filter box 20 needs to be replaced, the second baffle 14 is first removed, and then the filter box 20 is replaced. After the replacement is completed, the second baffle 14 is installed at one end of the first guide rail 11 and the second guide rail 12 facing the second support seat 51.
[0060] It is understood that the first baffle 13 can be mounted on the first and second guide rails 11 and 12 or on the housing, as long as it can block the filter box 20, and there is no limitation here. Similarly, the second baffle 14 can be mounted on the first and second guide rails 11 and 12 or on the housing, as long as it can block the filter box 20 and is removable, and there is no limitation here. The electronic device can be, for example, a camera, headphones, smartwatch, etc.
[0061] Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art will understand that the above examples are for illustration only and are not intended to limit the scope of the present disclosure. Those skilled in the art will understand that the above embodiments may be modified without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
