Description

Technical Field

[0001] This invention relates to the field of mechanical structure automation technology, and more particularly to an automatic clamping and sealing structure and its control method. Background Technology

[0002] Clamping devices are a common and widely used component in various industrial equipment. In existing technologies, the clamping and sealing of equipment interfaces typically involves manual operation in conjunction with the clamping structure. This traditional manual operation method has significant technical drawbacks in practical applications: First, during manual operation, it is difficult to achieve a uniform standard for clamping force. Due to the lack of precise quantitative control, different operators or even the same operator applying different forces under different conditions often vary. This variation leads to inconsistent clamping force on the equipment by the clamping device, making it difficult to guarantee the tightness and reliability of the sealing at the equipment interface. Second, when operating on interfaces requiring sealed enclosures, relying solely on manual experience makes it difficult to accurately control the start and end positions, failing to meet the high standards of automated sealing requirements.

[0003] Therefore, in order to overcome the defects of uneven clamping force and inconsistent standards in manual clamping, there is an urgent need for a solution that can use motors and sensors for precise control, so as to effectively solve the above problems and achieve automated clamping and sealing. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides an automatic clamping and sealing structure, comprising: an electrical structure, a transmission mechanism, and a mechanical structure; The electrical structure includes a motor and a position sensor, the transmission mechanism includes a rack and pinion, and the mechanical structure includes a pressure plate and a guide rail assembly. The motor controls the transmission between the gear and the rack, driving the clamping plate to clamp and seal other equipment; The guide rail assembly is configured to control the movement direction of the clamping plate; The position sensor is used to send signals to control the operation and shutdown status of the electrical structure.

[0005] Furthermore, the clamping force of the clamping plate is controlled by the number of steps the motor takes.

[0006] Furthermore, the position sensor is pre-set to control the start and end positions of the clamping plate; When the clamping plate reaches the designated position, the position sensor transmits a signal to the motor, controlling the motor to stop transmission, and the clamping plate stops its clamping and lifting actions.

[0007] The present invention also provides a control method for an automatic clamping and sealing structure, applied to the above-mentioned automatic clamping and sealing structure, comprising the following steps: S1. The electrical structure drives the mechanical structure, and the working and stopping states of the electrical structure are controlled by the signal from the position sensor, thereby controlling the state of the mechanical structure; S2. Control the motor to drive the transmission between the gear and the rack, thereby driving the clamping plate to clamp and seal the equipment that needs to be sealed; S3. The movement direction of the clamping plate is controlled by the guide rail assembly; S4. The clamping force of the clamping plate is controlled by the number of steps of the motor; the starting and ending positions of the clamping plate are controlled by the position sensor.

[0008] Furthermore, the step of controlling the start and end positions of the clamping plate through the position sensor specifically includes: when the clamping plate reaches the designated position, the position sensor transmits a signal to the motor to control the motor to stop transmission, and the clamping plate then stops the clamping and lifting actions.

[0009] Furthermore, when it is necessary to release the clamping plate, a signal is given to the motor to reverse the motor and release other equipment.

[0010] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. The present invention provides an automatic clamping and sealing structure and its control method, which controls the clamping force of the clamping device by controlling the number of motor operation steps, effectively solving the problem that the clamping force is difficult to achieve a uniform standard when the clamping structure is manually operated in the prior art, thereby ensuring the consistency and stability of the equipment sealing.

[0011] 2. The present invention provides an automatic clamping and sealing structure and its control method. By using a position sensor to pre-set the position, the starting and ending positions of the clamping device can be precisely controlled. When the device reaches the designated position, the transmission is automatically stopped, realizing automatic clamping and sealing of the interface of the box that needs to be sealed. The precise sealing process can be completed without manual intervention.

[0012] 3. The present invention provides an automatic clamping and closing structure and its control method. The movement direction of the clamping device is controlled by the guide rail combination, and the transmission method of gear and rack ensures the stability of the movement process. At the same time, the device can be released by giving the motor a signal to make it run in reverse. The entire clamping and releasing process is logically clear, easy to operate and easy to control.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] 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 following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples listed and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0020] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms 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 on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0021] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0022] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0023] Example 1 likeFigures 1 to 3 As shown, the present invention provides a control structure for an automated airtight door for a box, comprising: an electrical structure, a transmission mechanism, and a mechanical structure. Through the synergistic effect of these three parts, the mechanical structure tightly clamps and seals the interface of the device 7 that needs to be sealed.

[0024] Specifically, the electrical structure includes a motor 1 and a position sensor 2. The motor 1 serves as a power source and is connected to a transmission mechanism. The position sensor 2 is configured to emit signals and is connected to the motor 1 to control the operating and stopping states of the electrical structure. By controlling the start and stop of the motor 1 through signal feedback from the position sensor 2, automated control of the mechanical structure's state is achieved. This electrical control method replaces traditional manual operation, solving the problem of accurately controlling the start and stop positions when manually cooperating with the clamping structure.

[0025] The transmission mechanism includes a rack 4 and a gear 3. The output end of the motor 1 is connected to and drives the gear 3 to rotate, and the gear 3 meshes with the rack 4 for transmission. The rack 4 is connected to the clamping plate 5 in the mechanical structure. By controlling the transmission between the gear 3 and the rack 4, the motor 1 can convert its rotational motion into linear clamping motion, thereby effectively driving the clamping device formed by the clamping plate 5 to operate on other equipment. At the same time, the clamping force of the clamping device is controlled by the number of steps of the motor 1, thereby solving the problem that it is difficult to achieve a uniform standard for clamping force in the prior art, and realizing standardized automatic clamping.

[0026] The mechanical structure includes a clamping plate 5 and a guide rail assembly 6. The clamping plate 5 moves under the drive of a transmission mechanism to seal the interface of the enclosure that needs to be sealed. The guide rail assembly 6 is configured to cooperate with the clamping plate 5. The guide rail assembly 6 plays a crucial guiding role in the structure, controlling the direction of movement of the clamping device. This ensures that the clamping plate 5 remains stable during movement, accurately reaches the designated position for sealing, and guarantees the reliability and airtightness of the automatic clamping and sealing process.

[0027] Example 2 like Figure 4 As shown, based on the structure in Embodiment 1 above, this embodiment further provides a control method for the control structure of an automated airtight door for a housing. This method uses an electrical structure to drive a mechanical structure, achieving a tight mechanical closure and sealing of the interface of the device 7 to be sealed, thus realizing an automatic opening and closing sealing process. The method specifically includes the following steps: Step S1: Start-up and Transmission: First, the electrical structure drives the mechanical structure. The control motor 1 drives the gear 3 to rotate, the gear 3 drives the rack 4 that meshes with it to move, and in turn drives the pressure plate 5 to move towards the equipment that needs to be sealed.

[0028] Step S2: Directional Guidance: During the movement of the clamping plate 5, the guide rail assembly 6 always controls the movement direction of the clamping plate 5 to ensure that it can be accurately aligned with the interface of the equipment 7 that needs to be sealed.

[0029] Step S3: Position Control (Start and End Control): Position sensor 2 is configured to be pre-set to control the start and end positions of the clamping plate 5. When the clamping plate 5 reaches the designated position, position sensor 2 transmits a signal to motor 1, controlling motor 1 to stop transmission. At this time, the clamping plate 5 stops its clamping and lifting actions, completing precise position control.

[0030] Step S4: During the clamping process, the clamping force of the clamping plate 5 is controlled by the number of steps of the motor 1, thereby ensuring that the clamping force reaches a uniform standard and realizing the tight clamping and sealing of the mechanical structure.

[0031] In addition, the control method also includes the step of releasing the clamping plate 5: when it is necessary to release the clamping plate 5 (i.e., release the clamping on other equipment), a signal is sent to the motor 1. After receiving the signal, the motor 1 performs reverse operation, driving the clamping plate 5 to move in the opposite direction through the transmission of gear 3 and rack 4, thereby releasing other equipment and completing all the steps of automatic clamping and sealing.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
