Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coating, in particular to a flip opening and closing device and a coating equipment. BACKGROUND

[0002] In the coating equipment, the chamber cover needs to be opened for maintenance. However, due to the large shape and mass of the chamber cover, once the operation is failed or an accident occurs, the chamber cover may be out of control and flipped, which may damage the equipment and even cause serious safety accidents.

[0003] In addition, the current chamber cover usually uses an electric cylinder or other driving mechanism to achieve pushing. If the opening angle of the chamber cover is too large and exceeds the dead point position, the pushing force of the electric cylinder is too short for the force arm of the chamber cover hinge, and the torque provided by the electric cylinder cannot balance the torque generated by the self-weight of the chamber cover, which will cause the electric cylinder to be unable to drive the chamber cover, and even the electric cylinder is easily damaged, and the reliability is poor. Therefore, the chamber cover must move within a preset angle.

[0004] In order to solve the problem of limiting protection and safety after the chamber cover is opened, it is urgent to design a safety protection structure after the chamber cover is opened. SUMMARY

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] As disclosed in the background section, existing cavity cover opening and closing mechanisms typically use an electric cylinder to push the cavity cover to achieve the opening and closing of the opening. During the pushing process and after full opening, the pushing is achieved solely by the electric cylinder. However, as the opening angle of the cavity cover increases, the driving pressure of the electric cylinder also increases. When the opening angle of the cavity cover is too large and exceeds the dead point, the thrust of the electric cylinder and the lever arm of the cavity cover hinge become too short. The torque provided by the electric cylinder cannot balance the torque generated by the weight of the cavity cover itself. This can lead to the electric cylinder failing to drive the cavity cover, and may even damage the electric cylinder, resulting in poor reliability. Therefore, the cavity cover must move within a preset angle. This limits the opening angle of the cavity cover, and in actual operation, it is difficult to guarantee the opening angle of the cavity cover solely by the electric cylinder.

[0033] To address the aforementioned problems, embodiments of the present invention provide a novel flip-top opening and closing device and a coating equipment. It should be noted that, unless otherwise specified, the features in the embodiments of the present invention can be combined with each other.

[0034] See Figure 1 This invention provides a flip-top opening and closing device that can achieve limit protection after the cavity cover is opened, avoid excessive angle when opening the cavity cover, ensure the safety of opening the cover, and at the same time, will not damage the drive mechanism, thus improving reliability.

[0035] The flip-top opening and closing device 100 provided in this embodiment of the invention includes a support 110, a flip-top door panel 120, a door panel drive member 130, and a first locking mechanism 140. The support 110 is configured to be installed on the outer wall of a chamber 200, for example, on the outer side wall of the chamber 200, which has an opening. One edge of the flip-top door panel 120 is hinged to the support 110, and the flip-top door panel 120 is configured to be movably disposed at the opening. The door panel drive member 130 is tractively connected to the flip-top door panel 120 and is configured to drive the flip-top door panel 120 to rotate relative to the support 110 to open or close the opening. The first locking mechanism 140 is disposed between the support 110 and the door panel drive member 130 and is configured to lock the tractive connection between the flip-top door panel 120 and the door panel drive member 130 when the opening is open.

[0036] It should be noted that in this embodiment, the flip door panel 120 can rotate relative to the support 110 under the driving action of the door panel drive member 130, thereby opening or closing the opening of the chamber 200. The chamber 200 is preferably a vacuum coating chamber. Of course, the chamber 200 can also be a chamber for implementing other processes, which is not specifically limited here.

[0037] It is worth noting that, by adding a first locking mechanism 140, the embodiment of the present invention can achieve limit protection after the flip door panel 120 is opened, avoid the angle of the flip door panel 120 being too large when it is opened, ensure the safety of the opening process, and at the same time reduce the driving pressure of the door panel drive component 130, so as not to damage the door panel drive component 130, and improve the reliability of the drive mechanism.

[0038] In some embodiments, a pull rod shaft 123 is rotatably provided on the outer side of the flip door panel 120. The door panel drive member 130 is connected to the pull rod shaft 123 and is configured to pull the pull rod shaft 123 to make the flip door panel 120 rotate relative to the support 110. The first locking mechanism 140 is configured to hold and lock both ends of the pull rod shaft 123 when the flip door panel 120 rotates a preset angle relative to the support 110 from the closed state.

[0039] Furthermore, the outer surface of the flip door panel 120 is provided with an outwardly protruding tension reinforcing frame 121. A transmission seat 122 is provided on the tension reinforcing frame 121, and a pull rod shaft 123 is rotatably provided on the transmission seat 122. The door panel drive member 130 is connected to the pull rod shaft 123 and is configured to pull the pull rod shaft 123 during the opening process, so that the flip door panel 120 rotates relative to the support 110. Specifically, the tension reinforcing frame 121 is integrally provided on the outer surface of the flip door panel 120, the door panel drive member 130 can pull the pull rod shaft 123, and the pull rod shaft 123 is tractably connected to the transmission seat 122, thus realizing the rotational opening and closing of the flip door panel 120. When the flip door panel 120 rotates from the closed state to a preset angle, it can be considered that the cavity cover has fully opened the opening of the cavity 200. At this time, the first locking mechanism 140 can hold the two ends of the locking lever shaft 123 from both ends, thereby limiting the position of the lever shaft 123 and preventing the position of the lever shaft 123 from moving and affecting the position of the flip door panel 120, thus achieving the locking of the flip door panel 120.

[0040] It should be noted that the outer surface of the flip door panel 120 here refers to the surface of the flip door panel 120 away from the chamber 200, and the outward protrusion of the tension reinforcing frame 121 refers to the protrusion of the tension reinforcing frame 121 towards the side away from the chamber 200. The protruding tension reinforcing frame 121 allows the position of the transmission seat 122 to be spaced apart from the hinge position of the flip door panel 120, increasing the torque and facilitating better rotation of the flip door panel 120. Furthermore, the preset angles mentioned in this embodiment refer to the rotation angle of the flip door panel 120 relative to the support support 110 from the closed state to the open state. For example, the rotation angle of the flip door panel 120 in the closed state can be set to 0°.

[0041] In this embodiment, the door panel drive component 130 can be a different type of drive structure, such as an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. Preferably, it is an electric cylinder, and the output shaft of the electric cylinder is connected to the tension shaft. The clamping lock mentioned in this embodiment refers to locking the pull rod shaft 123 after the two first locking mechanisms 140 come close together.

[0042] See also Figure 1 and Figure 2 Furthermore, the tension-reinforcing frame 121 includes a longitudinal reinforcing plate 124 and a transverse tension plate 125. The longitudinal reinforcing plate 124 extends longitudinally, while the flip-top door panel 120 is hinged to the support bracket 110 along one longitudinal edge. There are two longitudinal reinforcing plates 124, integrally formed on the outer surface of the flip-top door panel 120 and spaced apart from each other. The two ends of the transverse tension plate 125 are respectively connected to the ends of the two longitudinal reinforcing plates 124 near the support bracket 110 and extend laterally. The transverse tension plate 125 is perpendicular to the longitudinal reinforcing plates 124, and the transmission seat 122 is fixedly disposed in the middle of the transverse tension plate 125. By providing the longitudinal reinforcing plate 124, the structural strength of the flip-top door panel 120 can be improved, and tension transmission can be achieved. By setting the transverse tension plate 125, on the one hand, the two longitudinal reinforcing plates 124 can be connected into one, further improving the structural strength; on the other hand, it can also support the transmission seat 122, so that the tensile force can be transmitted more evenly to the two longitudinal reinforcing plates 124 and the flip door panel 120.

[0043] It should be noted that in this embodiment, there are also two bearing supports 110. The two bearing supports 110 are spaced apart on the outer wall of the chamber 200. The flip door panel 120 is provided with two hinged ears 126 along one longitudinal edge. The two hinged ears 126 can be respectively hinged to the two bearing supports 110.

[0044] Furthermore, in order to enhance the structural strength of the hinge, in this embodiment, the two hinge lugs 126 are respectively connected to the root edges of the two longitudinal reinforcing plates 124. Preferably, a thickening plate 127 can be additionally designed at the connection between the hinge lugs 126 and the longitudinal reinforcing plates 124. The thickening plate 127 is integrally connected to the hinge lugs 126 and the longitudinal reinforcing plates 124, which can further enhance the structural strength of the hinge.

[0045] See also Figures 4 to 7In some embodiments, there are two first locking mechanisms 140, which are arranged at a distance from each other to form a clamping and receiving space 141. Each first locking mechanism 140 is provided with a limiting groove 142. At least a portion of the two first locking mechanisms 140 are configured to selectively move closer to or further away from each other, so that the two limiting grooves 142 cooperate to lock at both ends of the pull rod shaft 123 or release the locking of the pull rod shaft 123. Specifically, during the process of the flip door panel 120 opening the opening of the cavity 200, the door panel drive member 130 can pull the tension shaft and the transmission seat 122 to move into the receiving space 141. When the flip door panel 120 rotates to a preset angle, it can be considered to be in the open state. At this time, the tension shaft can move into the receiving space 141 under the drive of the door panel drive component 130. At this time, the limiting groove 142 and the end of the tension shaft can correspond to each other, and the two first locking mechanisms 140 can move closer to each other, so that the limiting groove 142 is locked at the end of the pull rod shaft 123, thereby preventing the pull rod shaft 123 from moving further, thus achieving locking. When unlocking, the two first locking mechanisms 140 can move away from each other, so that the limiting groove 142 disengages from the end of the pull rod shaft 123, thus achieving unlocking.

[0046] It should be noted that the two ends of the pull rod shaft 123 can protrude relative to the transmission seat 122, so as to facilitate the engagement of the limiting groove 142 with the end of the pull rod shaft 123.

[0047] Further, the first locking mechanism 140 includes a locking seat 143, a locking piece 144, and a locking drive member 145. The locking drive member 145 is disposed on the locking seat 143, the bottom end of the locking piece 144 is hinged to the locking seat 143, and a limiting groove 142 is disposed on the top of the locking piece 144. The locking drive member 145 is pulsatorically connected to the locking piece 144 and configured to drive the locking piece 144 to rotate relative to the locking seat 143, so that the tops of the locking pieces 144 move closer together or further apart. Specifically, the locking seat 143 can be fixedly disposed on an external frame, the locking piece 144 is hinged to the top of the locking seat 143 and extends upward, and the two limiting grooves 142 are respectively disposed on opposite sides of the two locking pieces 144 and located in the top region. Under the drive of the locking drive member 145, the locking pieces 144 can move closer together or further apart, thereby changing the position of the limiting grooves 142. The shape of the limiting groove 142 is adapted to the end shape of the pull rod shaft 123, and the size of the limiting groove 142 is slightly larger than the end size of the pull rod shaft 123.

[0048] It should be noted that the locking seat 143 is positioned outside the travel stroke of the transmission seat 122. The locking seat 143 includes a mounting portion 146 and a connecting portion 147 connected to each other. The mounting portion 146 and the connecting portion 147 form an L-shaped bent structure. The mounting portion 146 is fixed to the external frame, and the connecting portion 147 is located at the edge of the mounting portion 146 and protrudes upward. The bottom end of the locking piece 144 is hinged to the top end of the connecting portion 147. Furthermore, the two mounting portions 146 can be arranged opposite to each other. The locking drive member 145 can be a cylinder, with one end hinged to the mounting portion 146 and the other end hinged to the top end of the locking piece 144, thereby stably driving the locking piece 144 to rotate relative to the locking seat 143.

[0049] In some embodiments, the preset angle is greater than or equal to 90°. Specifically, the preset angle can be between 90° and 100°, for example, the preset angle can be any value among 90°, 95°, or 100°, or a value between any two points. Preferably, the preset angle can be slightly greater than 90°, so as to ensure that the opening of the chamber 200 is fully opened while avoiding excessive opening angle that would cause excessive driving pressure on the door panel drive component 130.

[0050] See also Figure 1 , Figure 8 , Figure 9 and Figure 10 In some embodiments, the flip-top opening and closing device 100 further includes a second locking mechanism 150. The second locking mechanism 150 is configured to be installed on the outer wall of the chamber 200 and / or on the support 110, and is configured to engage and lock the tension reinforcing frame 121 when the flip-top door panel 120 rotates relative to the support 110 from the closed state by a preset angle. Specifically, the second locking mechanism 150 can be disposed on the outer wall of the chamber 200 and close to the support 110. The second locking mechanism 150 can limit the tension reinforcing frame 121 when the flip-top door panel 120 is in the open state, thereby achieving auxiliary locking of the flip-top door panel 120. This ensures that the flip-top door panel 120 is still positioned even if the clamping locking mechanism fails, thus achieving limit protection.

[0051] Furthermore, the second locking mechanism 150 includes a positioning plate 151 and a positioning pin 152. The positioning plate 151 is located outside the rotational stroke of the tension reinforcing frame 121 and is configured to be installed on the outer side wall of the support 110. The positioning pin 152 is detachably mounted on the positioning plate 151. The flip-top door panel 120 is provided with a locking pin hole 154. The positioning pin 152 is configured to be inserted into the locking pin hole 154 when the flip-top door panel 120 rotates relative to the support 110 at a preset angle.

[0052] Furthermore, the positioning plate 151 has a positioning pin hole 153, and the tension reinforcing frame 121 has a locking pin hole 154. The locking pin hole 154 is configured to be concentrically aligned with the positioning pin hole 153 when the flip door panel 120 rotates relative to the bearing support 110 by a preset angle. The positioning pin 152 is detachably mounted in the positioning pin hole 153 and is configured to pass through the positioning pin hole 153 and the locking pin hole 154 in the aligned state, so that the tension reinforcing frame 121 and the positioning plate 151 remain relatively fixed. Specifically, the positioning plate 151 can be fixed to the outer wall of the chamber 200 by bolts, and the positioning plate 151 can be located on the side of one bearing support 110 away from the other bearing support 110. At the same time, in the longitudinal direction, the positioning plate 151 and the tension reinforcing frame 121 can be misaligned, thereby ensuring that the positioning plate 151 is outside the rotation stroke of the tension reinforcing frame 121.

[0053] It should be noted that the positioning pin 152 is a detachable structure. When the flip door panel 120 is not opened and rotated to the correct position (e.g., in the closed state or during the opening process), the positioning pin 152 can be removed from the positioning pin hole 153 to ensure that the rotation of the tension reinforcing frame 121 is not affected by the positioning plate 151 and the positioning pin 152. When the flip door panel 120 is opened and rotated to the correct position (e.g., rotated to the preset angle and in the open state), the locking pin hole 154 on the tension reinforcing frame 121 coincides and aligns with the positioning pin hole 153 on the positioning plate 151. The positioning pin 152 can be inserted into the positioning pin hole 153. Since the locking pin hole 154 and the positioning pin hole 153 are concentrically aligned at this time, the positioning pin 152 can also be inserted into the locking pin hole 154, thereby keeping the tension reinforcing frame 121 and the positioning plate 151 relatively fixed, achieving the locking and positioning of the flip door panel 120. When it is necessary to close the flip door panel 120, the positioning pin 152 can be removed first, and then the door panel can be closed. This can also prevent the flip door panel 120 from closing uncontrollably due to unexpected situations.

[0054] In some embodiments, the positioning plate 151 is further provided with a placement support plate 155, and the placement support plate 155 is provided with a placement hole 156, which is configured to place the positioning pin 152 removed from the positioning pin hole 153. Specifically, the placement support plate 155 is a horizontal plate, and the diameter of the placement hole 156 is smaller than the cap diameter of the positioning pin 152, so that the positioning pin 152 removed from the positioning pin hole 153 can be placed in the placement hole 156 for easy access, while also preventing the removed positioning pin 152 from being lost.

[0055] See Figures 1 to 3In some embodiments, the flip-top opening and closing device 100 further includes a flexible limiting mechanism 160, which is configured to elastically abut against the tension reinforcing frame 121 when the flip-top door panel 120 rotates relative to the support 110 from the closed state by a preset angle. Specifically, the flexible limiting mechanism 160 is disposed on the outer wall of the support 110 and located within the rotation stroke of the flip-top door panel 120. The flexible limiting mechanism 160 can elastically abut against the tension reinforcing frame 121 when the flip-top door panel 120 is opened, thereby providing a certain elastic resistance to prevent the flip-top door panel 120 from tipping backward under its own weight, and also to act as a buffer to prevent overload damage to the door panel drive component 130. Simultaneously, the flexible limiting mechanism 160 can also limit the end of the flip-top door panel 120, thus preventing the flip-top door panel 120 from opening too wide even if both the first locking mechanism 140 and the second locking mechanism 150 fail, thereby limiting the opening angle of the flip-top door panel 120.

[0056] Furthermore, the flexible limiting mechanism 160 includes an elastic element 161 and a limiting head 162. An assembly hole 163 is provided on the outer wall of the support 110. One end of the limiting head 162 is movably assembled in the assembly hole 163, and the other end protrudes in a direction away from the support 110, configured to abut against the flip-up door panel 120, specifically against the tension reinforcing frame 121. The elastic element 161 is disposed within the assembly hole 163 and elastically abuts against the limiting head 162, configured to provide elastic force to the limiting head 162 in a direction away from the support 110.

[0057] Specifically, the limiting head 162 includes a top-holding cap 164 and a support shaft 165 connected to each other. The support shaft 165 is rod-shaped and movably mounted in the mounting hole 163, with one end of the support shaft 165 extending out of the mounting hole 163. The top-holding cap 164 is located at the end of the support shaft 165 that extends out of the mounting hole 163. The diameter of the top-holding cap 164 is larger than the diameter of the mounting hole 163, and it is configured to hold against the tension reinforcing frame 121. The elastic element 161 can be a disc spring or a spring. The elastic element 161 is mounted inside the mounting hole 163 and abuts against the support shaft 165, thereby providing a certain elastic force to achieve elastic holding between the top-holding cap 164 and the tension reinforcing frame 121. Therefore, it can provide elastic force to prevent the flip-top door panel 120 from flipping backward, and the top-holding cap 164 has a certain buffering capacity to prevent damage to the electric cylinder due to overload.

[0058] Furthermore, the elastic element 161 can be sleeved on the support shaft 165, and a partial protrusion in the middle of the support shaft 165 forms a convex ring 167. The size of the convex ring 167 is adapted to the size of the mounting hole 163. One end of the elastic element 161 abuts against the bottom wall step of the mounting hole 163, and the other end abuts against the convex ring 167, thereby achieving elastic support for the support shaft 165. Simultaneously, a baffle 168 can be detachably mounted at the opening of the mounting hole 163. The baffle 168 surrounds the support shaft 165 and has a clearance hole with a size between the outer diameter of the support shaft 165 and the inner diameter of the mounting hole 163, through which the support shaft 165 passes. Furthermore, the inner diameter of the clearance hole is smaller than the outer diameter of the convex ring 167. By setting the baffle 168, the convex ring 167 can be limited, preventing the support shaft 165 from dislodging from the mounting hole. Of course, in other embodiments of the present invention, the elastic element 161 may also adopt different installation methods. Any installation method that can provide elastic force to the limiting head 162 in a direction away from the bearing support 110 is within the protection scope of the present invention.

[0059] In some embodiments, a stop block 166 is also provided on the tension reinforcing frame 121. Specifically, the stop block 166 is formed by a partial protrusion on the side of the tension reinforcing frame 121 near the door panel drive member 130. The stop block 166 is configured to abut against the limiting head 162 when the flip door panel 120 rotates relative to the support support 110 from the closed state by a preset angle. Specifically, the stop block 166 is integrally provided on the side wall of the longitudinal reinforcing plate 124 near the door panel drive member 130. When the flip door panel 120 is in the open state, the stop block 166 can abut against the limiting head 162, thereby preventing the flip door panel 120 from rotating further.

[0060] It should be noted that the cavity cover opening and closing mechanism provided in this embodiment of the invention utilizes the first locking mechanism 140, the second locking mechanism 150, and the flexible limiting mechanism 160 to achieve triple limiting protection after the cavity cover is opened, ensuring the safety of opening the cover, while not causing overload damage to the door panel drive component 130, greatly improving the reliability of the overall device and greatly improving the safety level.

[0061] This invention also provides a coating device, including a frame, a chamber 200, and the aforementioned flip-top opening and closing device 100. The flip-top opening and closing device 100 includes a support 110, a flip-top door panel 120, a door panel drive member 130, and a first locking mechanism 140. One edge of the flip-top door panel 120 is hinged to the support 110. The door panel drive member 130 is tractively connected to the flip-top door panel 120 and is configured to drive the flip-top door panel 120 to rotate relative to the support 110. The first locking mechanism 140 is disposed between the support 110 and the door panel drive member 130 and is configured to lock the flip-top door panel 120 when the opening is open. The bearing support 110 is disposed on the outer wall of the chamber 200, and the flip door panel 120 is movably disposed at the opening of the chamber 200 and is configured to open or close the opening under the drive of the door panel drive member 130. The door panel drive member 130 and the first locking mechanism 140 are both disposed on the frame.

[0062] In summary, this invention provides a flip-top opening and closing device 100 and a coating device. The flip-top opening and closing device 100 has a support 110 mounted on the outer wall of a chamber 200. One edge of a flip-top door panel 120 is hinged to the support 110, and the flip-top door panel 120 is movably disposed at the opening of the chamber 200. A door panel drive member 130 is connected to the flip-top door panel 120 and can drive the flip-top door panel 120 to rotate relative to the support 110, thereby opening or closing the opening. A first locking mechanism 140 is also provided between the support 110 and the door panel drive member 130. The first locking mechanism 140 can hold and lock the flip-top door panel 120 when the opening of the chamber 200 is opened, thereby locking and positioning the chamber door panel in the open state. Compared with the prior art, the embodiments of the present invention, by adding a first locking mechanism 140, a second locking mechanism 150 and a flexible limiting mechanism 160, can achieve limiting protection after the flip door panel 120 is opened, avoid excessive angle when opening the flip door panel 120, ensure the safety of the opening process, and at the same time reduce the driving pressure of the door panel drive component 130, so as not to damage the door panel drive component 130, and improve the reliability of the drive mechanism.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
