Abstract

This application relates to the field of hot pressing technology, and discloses a decontamination mechanism and a hot pressing device. The decontamination mechanism includes a scraper assembly and a support assembly. The scraper assembly is used to contact the surface to be cleaned and can move relative to the surface to be cleaned along a first direction. The support assembly is used to support the scraper assembly and includes a retaining member. The retaining member is provided on at least one side of the scraper assembly along the first direction, and the retaining member abuts against the scraper assembly. By setting the retaining member to abut against the scraper assembly, this application can better maintain the scraper assembly in its initially set decontamination posture. At the same time, during the relative movement of the scraper assembly and the surface to be cleaned along the first direction, the force acting on the scraper assembly due to friction between the two can be transmitted to the retaining member, effectively preventing the scraper assembly from deforming due to frequent and long-term bearing of this force. This solves the problem of easy deformation of oil scraping mechanisms in related technologies, enabling the scraper assembly to maintain effective contact with the surface to be cleaned for a long time and ensuring the decontamination effect of the decontamination mechanism.

Description

Technical Field

[0001] This application relates to the field of hot pressing technology, and in particular to a decontamination mechanism and a hot pressing device. Background Technology

[0002] In related technologies, some hot pressing equipment generates oil stains during operation. To prevent oil stains from corroding the equipment, an oil scraping mechanism is usually installed to remove the oil stains from the surface to be cleaned. Currently, most oil scraping mechanisms are contact-type, meaning the scraping mechanism contacts and moves relative to the surface to be cleaned. This type of scraping mechanism is subject to forces exerted by the surface during its relative movement. However, the load-bearing capacity of current scraping mechanisms is relatively weak, and long-term, frequent exposure to these forces can easily cause deformation, resulting in ineffective contact between the scraping mechanism and the surface to be cleaned, thus compromising the cleaning effect.

[0006] According to some embodiments of this application, the scraper assembly is configured to move along the second direction; wherein: The supporting member includes a main body and a sliding part. The main body and the sliding part are connected as an integral structure. The sliding part is connected to one end of the main body near the scraper assembly.

[0009] According to some embodiments of this application, the connecting assembly includes a connector and an elastic member. The two ends of the connector are respectively connected to the support member and the scraper assembly. The elastic member is sleeved on the connector and abuts between the support member and the scraper assembly. The scraper assembly can abut against the surface to be cleaned under the elastic force of the elastic member.

[0010] According to some embodiments of this application, the scraper assembly includes a mounting base and a scraper connected to the mounting base, the scraper being used to contact the surface to be cleaned, and the abutment abutting member abutting against the mounting base.

[0011] According to some embodiments of this application, the mounting base is provided with a receiving groove, the scraper is disposed in the receiving groove and partially extends out of the receiving groove for contacting the surface to be cleaned; the mounting base includes two side plates defining the receiving groove, the two side plates respectively abutting against opposite sides of the scraper along the first direction.

[0012] According to a second aspect of the present application, a hot pressing device is provided, including a door body and a cleaning mechanism as described in any of the above embodiments. The door body is provided with the surface to be cleaned, and the scraper assembly of the cleaning mechanism is in contact with the surface to be cleaned.

[0016] The decontamination mechanism according to the embodiments of this application has at least the following beneficial effects: This application provides a retaining member on at least one side of the scraper assembly along the first direction. The retaining member abuts against the scraper assembly, which allows the scraper assembly to better maintain its initial cleaning posture. At the same time, during the relative movement of the scraper assembly and the surface to be cleaned along the first direction, the force acting on the scraper assembly due to friction between the two can be transmitted to the retaining member. This effectively prevents the scraper assembly from deforming due to frequent and long-term exposure to this force, solving the problem of easy deformation of the oil scraping mechanism in related technologies. This allows the scraper assembly to maintain effective contact with the surface to be cleaned for a long time, ensuring the cleaning effect of the cleaning mechanism.

[0020] The following will clearly and completely describe the concept and technical effects of this application in conjunction with embodiments, so as to fully understand the purpose, features and effects of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0023] This application provides a decontamination mechanism and a hot pressing device.

[0024] The hot pressing device provided in this application is mainly used for pressing PCB boards. Of course, this hot pressing device can also be used for pressing other electronic components that require bonding. The hot pressing device may include a housing, a door, a pressure applying mechanism, and a heating mechanism. The door is used to open or close the housing. The pressure applying mechanism and the heating mechanism are disposed in the housing. The pressure applying mechanism is used to apply pressure to the inner core board and the prepreg of the PCB board, and the heating mechanism is used to generate heat to fuse the inner core board and the prepreg through high temperature and high pressure.

[0025] During the hot pressing process of PCB boards, halogenated volatile substances such as formaldehyde and benzene are generated. These volatile substances are highly viscous, and when they come into contact with the relatively cool surface of the door, they easily condense into droplets and flow along the surface. If no treatment is taken, the droplets will continuously accumulate, flow, and leak out of the casing, corroding the anti-corrosion paint layer on the casing surface, damaging the appearance and structural safety of the hot pressing device, and the leaked volatile substances will pollute the workshop, increase the concentration of harmful substances in the air, and affect human health.

[0026] The decontamination agency provided in this application can solve the above problems. Please refer to [the relevant documentation / reference]. Figure 2 and Figure 3 The cleaning mechanism 300 includes a scraper assembly 310, which is used to contact the surface to be cleaned. The scraper assembly 310 is capable of moving relative to the surface to be cleaned along a first direction Z. Through the relative movement between the scraper assembly 310 and the surface to be cleaned, a scraping action is achieved on the surface to be cleaned, which can remove oil stains from the surface to be cleaned.

[0027] Understandably, the scraper assembly 310 moves relative to the surface to be cleaned along the first direction Z. It can be configured such that the scraper assembly 310 is stationary along the first direction Z, while the surface to be cleaned is driven to move along the first direction Z; or, it can be configured such that the surface to be cleaned is stationary along the first direction Z, while the scraper assembly 310 is driven to move along the first direction Z; or, both the scraper assembly 310 and the surface to be cleaned move along the first direction Z.

[0028] When the cleaning mechanism 300 is applied to the hot press device, the surface to be cleaned can be the side of the door facing the inner cavity of the housing, i.e., the inner surface of the door. By bringing the scraper assembly 310 into contact with the inner surface of the door, the scraper assembly 310 can scrape off the condensed droplets on the inner surface of the door as there is relative movement between the scraper assembly 310 and the door.

[0029] However, during the movement of the surface to be cleaned, due to the contact friction between the surface to be cleaned and the scraper assembly 310, a force is generated on the scraper assembly 310 along the direction of movement (first direction Z). If no treatment is done, the scraper assembly 310 is prone to deformation along the first direction Z due to frequent and long-term exposure to this force, which will cause the scraper assembly 310 to fail to make effective contact with the surface to be cleaned, thus affecting the cleaning effect.

[0030] To address this, the cleaning mechanism 300 is also equipped with a support component 320, which supports the scraper assembly 310. Please refer to [reference needed]. Figure 3 The support component 320 includes a retainer 322. The scraper assembly 310 is provided with a retainer 322 on at least one side along the first direction Z, and the retainer 322 abuts against the scraper assembly 310.

[0031] Understandably, the abutment 322 can be provided on one side of the scraper assembly 310 along the first direction Z, or it can be provided on both opposite sides of the scraper assembly 310 along the first direction Z. The abutment 322 can be flexibly set according to the specific installation position of the scraper assembly 310.

[0032] This application provides a retaining member 322 on at least one side of the scraper assembly 310 along the first direction Z. By having the retaining member 322 abut against the scraper assembly 310, the scraper assembly 310 can better maintain its initially set cleaning posture. At the same time, during the relative movement of the scraper assembly 310 and the surface to be cleaned along the first direction Z, the force acting on the scraper assembly 310 due to friction between the two can be transmitted to the retaining member 322, effectively preventing the scraper assembly 310 from deforming due to frequent and long-term exposure to this force. This allows the scraper assembly 310 to maintain effective contact with the surface to be cleaned for a long time, ensuring the cleaning effect of the cleaning mechanism 300.

[0033] Please refer to the reference. Figure 1 and Figure 3 The scraper assembly 310 abuts against the surface to be cleaned along the second direction X, which intersects with the first direction Z. In this way, the direction of force applied by the scraper assembly 310 on the surface to be cleaned intersects with the direction of relative movement between the scraper assembly 310 and the surface to be cleaned. The scraper assembly 310 can generate greater pressure on the surface to be cleaned and can better scrape off the oil stains on the surface to be cleaned.

[0034] In one embodiment of this application, to facilitate the cooperation between the scraper assembly 310 and the support assembly 320 and to facilitate the overall assembly of the cleaning mechanism 300, the second direction X is perpendicular to the first direction Z. The following embodiments are mainly described with the second direction X being perpendicular to the first direction Z as an example.

[0035] Understandably, the scraper assembly 310 moves relative to the surface to be cleaned along the first direction Z, and the scraper assembly 310 abuts against the surface to be cleaned along the second direction X. To increase the contact area and improve the cleaning efficiency, the scraper assembly 310 can extend along a third direction Y, which is perpendicular to the first direction Z and the second direction X. For ease of explanation, combined with... Figure 3 As shown, in the spatial three-dimensional coordinate system constructed in this application, the first direction can be the Z-axis direction of the three-dimensional coordinate system, the second direction can be the X-axis direction, and the third direction can be the Y-axis direction. That is, the scraper assembly 310 moves relative to the surface to be cleaned along the first direction Z, the scraper assembly 310 abuts against the surface to be cleaned along the second direction X, and the scraper assembly 310 extends along the third direction Y. Correspondingly, at least one side of the scraper assembly 310 along the first direction Z is provided with a supporting member 322.

[0036] Please refer to the reference. Figure 2 and Figure 3The support assembly 320 also includes a support member 321, and the cleaning mechanism 300 also includes a connecting assembly 330. The scraper assembly 310 is connected to the support member 321 through the connecting assembly 330. To ensure that the scraper assembly 310 is always in contact with the surface to be cleaned, the connecting assembly 330 includes a connecting member 331 and an elastic member 332. The two ends of the connecting member 331 are respectively connected to the support member 321 and the scraper assembly 310. The elastic member 332 is sleeved on the connecting member 331 and abuts against the support member 321 and the scraper assembly 310. The scraper assembly 310 can abut against the surface to be cleaned under the elastic force of the elastic member 332.

[0037] It is important to understand that the elastic element 332 can initially be in a compressed state. The elastic force generated by the compression deformation of the elastic element 332 acts on the scraper assembly 310 and the support member 321. During the movement of the surface to be cleaned along the first direction Z, there may be a slight offset along the second direction X. Specifically, when the surface to be cleaned offsets away from the scraper assembly 310, the elastic force generated by the elastic element 332 pushes the scraper assembly 310 to move and contact the surface to be cleaned. When the surface to be cleaned offsets towards the scraper assembly 310, the scraper assembly 310 can also contact the surface to be cleaned under the action of the elastic force. In this way, the scraper assembly 310 can move with the offset of the surface to be cleaned along the second direction X under the action of the elastic force, ensuring that the scraper assembly 310 is always in contact with the surface to be cleaned. The elastic element 332 can be a spring or a sheet spring.

[0038] like Figure 3 As shown, in one embodiment of this application, the connector 331 can be a stud 3311. One end of the stud 3311 can be welded or bonded to the scraper assembly 310, and the other end of the stud 3311 passes through the support member 321. A nut (not shown) is connected to one end of the stud 3311 that passes through the support member 321.

[0039] Since the abutment 322 abuts against the scraper assembly 310, this improves the smoothness of the scraper assembly 310's movement along the second direction X. For some embodiments of this application, please refer to... Figure 4 The supporting member 322 includes a main body 3221 and a sliding part 3222. The sliding part 3222 is connected to the end of the main body 3221 near the scraper assembly 310, and the sliding part 3222 can slide or roll relative to the scraper assembly 310. The main body 3221 and the sliding part 3222 can be connected as an integral structure, that is, the main body 3221 and the sliding part 3222 are connected as a whole.

[0040] Understandably, by configuring the abutment 322 to include the main body 3221 and the sliding part 3222, when the scraper assembly 310 moves along the second direction X, the sliding part 3222 can slide or roll relative to the scraper assembly 310, reducing the frictional resistance between the abutment 322 and the scraper assembly 310, thereby enabling the scraper assembly 310 to move smoothly along the second direction X under the action of the elastic member 332, and thus ensuring that the scraper assembly 310 can reliably contact the surface to be cleaned with the real-time movement of the surface to be cleaned.

[0041] One possible implementation is that the sliding aid 3222 can be a sliding member connected to one end of the main body 3221, so that the sliding aid 3222 slides relative to the scraper assembly 310. The sliding member is made of a low-friction material to reduce the frictional resistance between the two. In one embodiment of this application, the sliding aid 3222 is a low-friction thrust washer.

[0042] Another possible implementation is that the sliding aid 3222 can be a rolling element rotatably connected to one end of the main body 3221, so that the sliding aid 3222 rolls relative to the scraper assembly 310, thereby reducing the frictional resistance between the two through rolling contact. In one embodiment of this application, combined with Figure 4 As shown, the supporting member 322 is configured as a ball plunger, the main body 3221 is the stud portion of the ball plunger, and the lubrication part 3222 is the ball portion of the ball plunger.

[0043] Please refer to Figure 5 In some other embodiments of this application, the cleaning mechanism 300 includes a first sliding aid 323 separately disposed from the supporting member 322. The first sliding aid 323 is disposed between the supporting member 322 and the scraper assembly 310, and the first sliding aid 323 can slide or roll relative to the scraper assembly 310. That is, in this embodiment, the first sliding aid 323 and the supporting member 322 are two independent components.

[0044] Similarly to the above embodiments, this embodiment provides a first sliding aid 323 between the supporting member 322 and the scraper assembly 310. The relative sliding or rolling of the first sliding aid 323 reduces the frictional resistance between the supporting member 322 and the scraper assembly 310, which is beneficial for the scraper assembly 310 to move smoothly along the second direction X.

[0045] One possible implementation is that the first sliding aid 323 can be connected to the scraper assembly 310 to prevent it from falling off. In one embodiment of this application, the first sliding aid 323 can be a roller rotatably connected to the surface of the scraper assembly 310. In another embodiment of this application, the first sliding aid 323 can be a low-friction thrust pad connected to the surface of the scraper assembly 310.

[0046] To ensure that the retaining member 322 is securely abutted against the scraper assembly 310, please refer to the following: Figure 3 The support assembly 320 further includes a support member 321, which includes a first support portion 3211. The scraper assembly 310 is provided with the first support portion 3211 at least on one side along the first direction Z. A retaining member 322 is connected to the first support portion 3211. By connecting the retaining member 322 to the first support portion 3211 of the support member 321, the first support portion 3211 provides support for the retaining member 322, allowing the retaining member 322 to firmly abut against the scraper assembly 310. It is understood that by making the first support portion 3211 spaced apart from the scraper assembly 310 along the first direction Z, the scraper assembly 310 will not scrape against the first support portion 3211 when moving along the second direction X, which is beneficial to the smoothness of the movement of the scraper assembly 310.

[0047] It should be understood that when the abutment member 322 is provided only on one side of the scraper assembly 310 along the first direction Z, the first support portion 3211 is also provided only on one side of the scraper assembly 310 along the first direction Z, and is located on the same side as the abutment member 322. When the abutment member 322 is provided on both opposite sides of the scraper assembly 310 along the first direction Z, then the first support portion 3211 is provided on both opposite sides of the scraper assembly 310 along the first direction Z.

[0048] Understandably, multiple abutment members 322 can be provided, and these multiple abutment members 322 can be arranged at intervals along a third direction Y. When there are multiple abutment members 322, the number of first support portions 3211 can be the same as the number of abutment members 322, combined with... Figure 2 As shown, each first support portion 3211 is connected to a supporting member 322, and multiple first support portions 3211 are arranged at intervals along the third direction Y. Alternatively, when there are multiple supporting members 322, the number of first support portions 3211 can be less than the number of supporting members 322. In one possible implementation, the scraper assembly 310 may have only one first support portion 3211 on one side along the first direction Z. By extending the first support portion 3211 along the third direction Y and setting it to an elongated shape, multiple supporting members 322 located on the same side of the scraper assembly 310 can be connected to the same first support portion 3211. It is understood that the accompanying drawings of the embodiments of this application are only illustrative examples and should not be considered as limitations on this application.

[0049] Please refer to Figure 3The support member 321 also includes a second support portion 3212, which is connected to the first support portion 3211 and located on the side of the scraper assembly 310 away from the surface to be cleaned. The scraper assembly 310 is connected to the second support portion 3212 via a connecting component 330. It is understood that the second support portion 3212 supports both the first support portion 3211 and the scraper assembly 310. Simultaneously, the second support portion 3212 can also be used to connect to external equipment, allowing the entire cleaning mechanism 300 to be installed on external devices. For example, the cleaning mechanism 300 can be installed on the hot press device 10 via the second support portion 3212.

[0050] Please continue to refer to this. Figure 3 The scraper assembly 310 includes a mounting base 311 and a scraper block 312 connected to the mounting base 311. The scraper block 312 is used to contact the surface to be cleaned, and the retaining member 322 abuts against the mounting base 311. It is understood that since the scraper block 312 cleans in contact with the surface to be cleaned, to prevent scratches on the surface, the scraper block 312 can be made of a low-hardness material; simultaneously, the scraper block 312 can also be made of a low-friction material to reduce the frictional resistance between the scraper block 312 and the surface to be cleaned. In some embodiments of this application, the material of the scraper block 312 can be hard low-friction nylon or Teflon.

[0051] In the above embodiment, the mounting base 311 is connected to the scraper 312. By abutting the support member 322 against the mounting base 311 instead of directly against the scraper 312, the support member 322 and the mounting base 311 can better bear force, avoiding the impact of the low hardness of the scraper 312 on the abutment reliability of the support member 322. Moreover, by connecting the scraper 312 to the mounting base 311, the mounting groove can provide a certain degree of support and limitation for the scraper 312, which helps to reduce the deformation of the scraper 312 caused by frequent relative movement with the surface to be cleaned, and improves the service life of the scraper 312.

[0052] like Figure 3 As shown, the mounting base 311 is provided with a receiving groove 3111, and the scraper 312 is disposed in the receiving groove 3111, with a portion extending out of the receiving groove 3111 for contact with the surface to be cleaned. The mounting base 311 includes two side plates 3112 defining the receiving groove 3111, and the two side plates 3112 respectively abut against opposite sides of the scraper 312 along the first direction Z. In this way, the scraper 312 is supported and limited by the two side plates 3112 along the first direction Z, which can reduce the compression deformation of the scraper 312 under long-term and frequent cleaning of the surface to be cleaned. Moreover, the scraper 312 only contacts the cleaning surface through the portion extending out of the receiving groove 3111, and the deformation of the scraper 312 mainly occurs at the end, further improving the service life of the scraper 312.

[0053] Mounting base 311 also includes a base plate 3113, with both ends of the base plate 3113 connected to two side plates 3112 respectively, and a connecting assembly 330 connected to the base plate 3113. To ensure that the connecting assembly 330 is subjected to uniform force, the connecting assembly 330 is connected to the middle of the base plate 3113.

[0054] When the aforementioned cleaning mechanism 300 is applied to the hot press device 10, the door body 200 is provided with a surface to be cleaned, and the scraper assembly 310 of the cleaning mechanism 300 contacts the surface to be cleaned of the door body 200, and the scraper assembly 310 can move relative to the door body 200.

[0055] The hot pressing device 10 of this application adopts the cleaning mechanism 300 conceived in the above embodiment. By bringing the scraper assembly 310 into contact with the surface of the door 200 to be cleaned, the scraper assembly 310 scrapes and cleans the surface of the door 200 as the relative movement between the door 200 and the scraper assembly 310 occurs. This can promptly remove condensed halogen droplets on the door 200, effectively improving the problem in related technologies where halogen droplets leak to the outside of the hot pressing device 10, causing corrosion of the housing 100 and air pollution.

[0056] The following is a detailed description of the installation of the cleaning mechanism 300 on the hot press device 10. Please refer to [link / reference]. Figure 1 (Should Figure 1 (Partial structure is hidden; only the lower half of the hot pressing device 10 is shown.) The hot pressing device 10 includes a housing 100, which has an inner cavity 102 and an opening 101 communicating with the inner cavity 102. The PCB board is pressed within the inner cavity 102. The door 200 can slide relative to the housing 100 to open or close the opening 101. The side of the door 200 facing the inner cavity 102 has a surface to be cleaned (i.e., the inner surface of the door 200), and the cleaning mechanism 300 is disposed in the inner cavity 102. As the door 200 moves, the scraper assembly 310 scrapes away the droplets on the surface to be cleaned on the door 200. That is, the relative movement between the two is directly achieved by the movement of the door 200, so there is no need to set a drive source for the scraper assembly 310, simplifying the overall structure of the cleaning mechanism 300.

[0057] Understandably, by placing the cleaning mechanism 300 in the inner cavity 102, the cleaning mechanism 300 cleans the inner surface of the door 200 from inside the housing 100, which helps the liquid scraped off by the scraper assembly 310 to fall into the inner cavity 102, preventing droplets from flowing along the door 200 to the outside of the housing 100. Moreover, the cleaning mechanism 300 is hidden inside the housing 100, so it is not visible from the outside of the hot press device 10, which contributes to the overall aesthetics of the hot press device 10.

[0058] Understandably, the door 200 is configured to slide along the first direction Z. In one possible implementation, the height direction of the door 200 can be the first direction Z, the thickness direction of the door 200 can be the second direction X, and the width direction of the door 200 can be the third direction Y. In this case, the door 200 slides vertically along the first direction Z. To fully scrape off the condensed droplets on the door 200, the scraper 312 can be extended horizontally along the third direction Y and configured as a long strip. In order to prevent the scraper 312 from bending and deforming due to excessive length, the mounting base 311 can also be designed to extend along the third direction Y. Alternatively, multiple mounting bases 311 can be configured along the third direction Y, and a scraper 312 can be supported by multiple mounting bases 311.

[0059] In another possible implementation (not shown in the figure), the width direction of the door body 200 is the first direction Z, the thickness direction of the door body 200 is the second direction X, and the height direction of the door body 200 is the third direction Y. In this implementation, the door body 200 slides horizontally along the first direction Z, and the scraper block 312 can be arranged vertically along the third direction Y.

[0060] Please refer to the reference. Figure 1 and Figure 3 The housing 100 includes an end plate 110, which is disposed in the inner cavity 102 and arranged along the first direction Z. The scraper assembly 310 is supported on the end of the end plate 110, and the abutment 322 abuts against the side of the scraper assembly 310 away from the end plate 110.

[0061] By supporting the scraper assembly 310 at the end of the end plate 110 and abutting the abutting member 322 against the side of the scraper assembly 310 away from the end plate 110, the opposite sides of the scraper assembly 310 are supported by the end plate 110 and abutted by the abutting member 322, respectively. Under the combined action of the two, the scraper assembly 310 is stably abutted and confined between the end plate 110 and the abutting member 322. Moreover, during the relative movement of the scraper assembly 310 and the door body 200, the force of friction between the two on the scraper assembly 310 is transmitted to the end plate 110 and the abutting member 322, which greatly prevents the scraper assembly 310 from deforming along the movement direction of the door body 200. This further facilitates stable and reliable contact between the scraper assembly 310 and the surface of the door body 200 to be cleaned, thereby improving the cleaning effect of the cleaning mechanism 300.

[0062] The second support part 3212 of the support member 321 can be connected and fixed to the end plate 110 by fasteners (such as bolts, rivets, etc.), so that the entire cleaning mechanism 300 is stably installed in the inner cavity 102.

[0063] In one embodiment of this application, the end plate 110 can be connected to the bottom wall 103 of the inner cavity 102, the scraper assembly 310 is supported on the top of the end plate 110, and the abutment 322 abuts against the upper side of the scraper assembly 310. Then, during the downward movement of the door 200 to open the opening 101, the scraper assembly 310 scrapes off the condensed oil on the inner surface of the door 200. This liquid is first scraped onto the upper side of the scraper assembly 310, and then, under the influence of gravity, flows downward along the end plate 110 to the bottom wall 103 of the inner cavity 102. This not only promptly removes the condensed droplets on the door 200, preventing halogenated liquid from leaking outside the housing 100, but also effectively prevents the oil from flowing along the door 200 to outside the housing 100 during the scraping process. Furthermore, it also achieves oil collection.

[0064] Understandably, when the scraper assembly 310 is supported on the end plate 110, the scraper assembly 310 can move relative to the scraper block 312 under the action of the elastic element 332. To ensure smooth movement of the scraper assembly 310, please refer to the reference... Figure 1 and Figure 3 A second sliding aid 324 is also provided between the scraper assembly 310 and the end plate 110. The second sliding aid 324 can slide or roll relative to the scraper assembly 310.

[0065] When the scraper assembly 310 moves relative to the end plate 110 under the action of the elastic member 332, the frictional resistance between the scraper assembly 310 and the end plate 110 is reduced through the relative sliding or rolling of the second sliding aid 324, further facilitating the smooth movement of the scraper assembly 310 and ensuring reliable contact between the scraper assembly 310 and the inner surface of the door body 200 as the door body 200 moves in real time. It is understood that multiple second sliding aids 324 can be provided along the length of the scraper assembly 310.

[0066] One possible implementation is that the second sliding aid 324 is configured as a sliding member, which is made of a low-friction material to reduce the frictional resistance between the end plate 110 and the scraper assembly 310. In one embodiment of this application, combined with... Figure 3 As shown, the second sliding aid 324 is a low-friction thrust washer.

[0067] Another possible implementation is that the second sliding aid 324 is set as a rolling element, which can roll between the end plate 110 and the scraper assembly 310, thereby reducing the frictional resistance between the end plate 110 and the scraper assembly 310 through rolling contact.

[0068] Understandably, to prevent the second sliding aid 324 from falling off, the second sliding aid 324 can be connected to the end plate 110, or the second sliding aid 324 can also be connected to the mounting base 311 of the scraper assembly 310. This application embodiment does not limit this.

[0069] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
