Description

Technical Field

[0001] The present application relates to the technical field of linear displacement device applications, and particularly to a displacement driving mechanism, a control method, a cleaning device, and a pole piece cutting device. Background Art

[0002] Displacement driving mechanisms such as cylinders, hydraulic cylinders, electric push rods, linear slides, etc. are widely used in manufacturing, for example, in the application of pole piece cleaning devices:

[0003] For the pole piece after laser or cutting treatment, it is necessary to wipe the dust on the surface of the pole piece through a pole piece cleaning device. The traditional pole piece cleaning device mainly includes two cleaning mechanisms arranged on opposite sides of the moving path of the pole piece, and the two cleaning mechanisms are used to wipe the surface of the pole piece moving along the moving path.

[0004] Before the pole piece is processed, threading work needs to be carried out. Due to the blocking effect of the brush in the cleaning mechanism, it is not easy to carry out the threading work of the pole piece. To solve this problem, at least one of the two cleaning mechanisms in the existing pole piece cleaning device is applied with a displacement driving mechanism so that the distance between the two cleaning mechanisms is adjustable, thereby facilitating the threading work. However, when carrying out the threading work, if the distance between the two cleaning mechanisms shrinks due to the failure of the displacement driving mechanism or the accidental touch of the control button of the displacement driving mechanism, it is easy to cause injury to the staff or the pole piece. Summary of the Invention

[0005] In view of this, the purpose of the present application is to provide a displacement driving mechanism, a control method, a cleaning device, and a pole piece cutting device to solve the technical problems existing in the background art.

[0006] To achieve the above technical purpose, the present application provides a displacement driving mechanism, including a linear displacement driver and a safety component;

[0007] The safety component includes a connecting piece, a stop piece, and a movable piece;

[0008] The connecting piece is connected to the driving end of the linear displacement driver and moves synchronously;

[0009] The movable piece is inserted through the connecting piece in a vertically movable manner;

[0010] The top surface of the stop piece forms a support surface, and can be in sliding contact with one end of the movable piece that extends downward through the connecting piece;

[0011] One side surface of the stop piece in the moving direction of the driving end of the linear displacement driver forms a stop surface, and can be in contact and abutted against the part of the movable piece below the support surface that leaves the support surface.

[0012] Further, the safety component further includes a controller and a sensor;

[0013] The sensor is installed on the stop surface and connected to the controller, and is used to sense the moving part leaving the support surface, and feedback a signal to the controller when the moving part is sensed;

[0014] The controller is used to control the linear displacement driver to execute the operation locking mode when receiving the signal.

[0015] Further, a limiting part is provided on the moving part, and is used to contact and abut against the support surface when the moving part moves down a certain distance relative to the connecting part after leaving the support surface;

[0016] The limiting part is provided on the part where the moving part penetrates downward through the connecting part.

[0017] Further, a magnetic attraction part is provided at the bottom of the connecting part and / or the limiting part;

[0018] The limiting part can be magnetically coupled with the connecting part through the magnetic attraction part.

[0019] Further, a separating part is further included;

[0020] The separating part is installed on the stop part and can be wedge-fitted with the limiting part, and is used for: during the process of the moving part moving towards the stop part, sliding relatively through the position where the limiting part is wedge-fitted, so that the limiting part moves in the direction of separating from the connecting part, so as to release the magnetic coupling with the magnetic attraction part.

[0021] Further, the magnetic attraction part is an electromagnet;

[0022] The controller is electrically connected to the magnetic attraction part and is used to control the magnetic attraction force of the magnetic attraction part.

[0023] Further, the limiting part is of an annular structure and is arranged around the moving part.

[0024] The present application also discloses a control method applied to the above improved displacement driving mechanism, including the steps:

[0025] The controller responds to the first control instruction, controls the driving end of the linear displacement driver to move, so that the moving part moves towards the stop surface of the stop part until it leaves the support surface of the stop part;

[0026] The controller responds to the signal fed back by the sensor after sensing the moving part, and controls the linear displacement driver to execute the operation locking mode;

[0027] In response to the second control instruction, the controller controls the magnetic member on the connecting member to generate magnetism, so as to adsorb the limiting portion on the movable member, making the movable member higher than the supporting surface;

[0028] In response to the third control instruction, the controller controls the driving end of the linear displacement driver to perform a reset movement, and when the driving end's reset movement is in place, controls the magnetic member to eliminate magnetism to release the limiting portion, making the movable member contact the supporting surface.

[0029] The present application also discloses a cleaning device, including two cleaning mechanisms. The two cleaning mechanisms are arranged at intervals and form a cleaning passage for the object to be cleaned to pass through. At least one of the two cleaning mechanisms is adjustably displaceably arranged through the above-improved displacement driving mechanism, so that the width of the cleaning passage is adjustable;

[0030] The linear displacement driver in the displacement driving mechanism is installed on the stopper, and the driving end of the linear displacement driver is connected to the corresponding cleaning mechanism;

[0031] The connecting member in the displacement driving mechanism is installed on the cleaning mechanism;

[0032] The stopping surface of the stopper is used to stop the adjustably displaceably arranged cleaning mechanism from moving in the direction of reducing the width of the cleaning passage.

[0033] The present application also discloses a pole piece cutting device, including the above-improved cleaning device, and the cleaning passage of the cleaning device allows the pole piece substrate to pass through.

[0034] As can be seen from the above technical solutions, in the displacement driving mechanism designed in the present application, the linear displacement driver is equipped with a safety component. By using this safety component, when the linear displacement driver drives the connecting member to move towards the stopping surface of the stopper, it also drives the movable member. When moving to a position where one end of the movable member passes through the connecting member downward and leaves the supporting surface, after losing the supporting effect of the supporting surface, the movable member moves downward relative to the connecting member by a certain distance. At this time, the part of the movable member below the supporting surface can contact and abut against the stopping surface on the stopper, thereby being able to prevent the linear displacement driver from resetting due to failure or accidental touching of the control button. That is to say, it can play a safety guarantee role for the linear displacement driver after the movement control, making the use of the displacement driving mechanism safer.

[0045] The following will clearly and completely describe the technical solutions of the embodiments of the present application in conjunction with the drawings. Obviously, the described embodiments are some embodiments of the embodiments of the present application, rather than all of them. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the embodiments of the present application.

[0046] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the embodiments of the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0047] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a replaceable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0048] The embodiments of the present application disclose a displacement driving mechanism, a control method, and a cleaning device.

[0049] Please refer to Figure 1 , an embodiment of the displacement driving mechanism provided in the embodiments of the present application includes:

[0050] A linear displacement driver 1 and a safety component. The linear displacement driver 1 can be a cylinder, a hydraulic cylinder, etc., and no specific limitation is made.

[0051] The safety component includes a connecting member 3, a stop member 2, and a movable member 4.

[0052] The connecting member 3 is connected to the driving end of the linear displacement driver 1 and moves synchronously. The connecting member 3 also plays a role of connection and fixation, and its specific structure can be designed according to actual needs, and no specific limitation is made.

[0053] The movable member 4 is inserted through the connecting member 3 in a vertically movable manner, that is, the movable member 4 can move up and down relative to the connecting member 3.

[0054] The top surface of the stop member 2 forms a support surface 21, which can be in sliding contact with one end of the movable member 4 that penetrates downward through the connecting member 3. The support surface 21 can support the movable member 4, and the sliding contact fit between it and the downward end of the movable member 4 will not interfere with the movement of the movable member 4. Based on this, one end of the movable member 4 in contact with the support surface 21 can be designed as an arc to reduce the contact friction force, and no specific limitation is made.

[0055] The stopper 2 forms a stopper surface 22 on one side in the moving direction of the driving end of the linear displacement driver 1, and can contact and abut against the part of the moving member 4 that is lower than the support surface 21 and leaves the support surface 21. When the moving member 4 moves away from the support surface 21, it moves downward relative to the connecting member 3 by a certain distance under the action of its own gravity. At this time, the part of the moving member 4 that is lower than the support surface 21 can contact and abut against the stopper surface 22 on the stopper 2, so as to prevent the linear displacement driver 1 from resetting due to failure or accidental touch of the control button. That is, it can play a safety guarantee role for the linear displacement driver 1 after the movement control, making the use of the displacement driving mechanism safer.

[0056] The above is the first embodiment of the displacement driving mechanism provided by the embodiment of the present application. The following is the second embodiment of the displacement driving mechanism provided by the embodiment of the present application. For details, please refer to Figures 1 to 3 。

[0057] Based on the solution of the above first embodiment:

[0058] Furthermore, the safety component further includes a controller and a sensing member 5.

[0059] The sensing member 5 is installed on the stopper surface 22 and is connected to the controller, and is used to sense the moving member 4 that leaves the support surface 21, and feedback a signal to the controller when the moving member 4 is sensed. The sensing of the sensing member 5 can be through contact with the interactive member or proximity to the moving member 4. For this reason, the sensing member 5 can be designed as a push sensor or a proximity sensor, and there is no specific limitation.

[0060] The controller is used to control the linear displacement driver 1 to execute the operation locking mode when receiving the signal. The operation locking mode is to disconnect the connection between the operation panel and the linear displacement driver 1, or lock the operation panel so that the operator cannot operate the linear displacement driver 1 through the operation panel, thereby avoiding accidental touch. The controller can be a PLC control module, a microprocessing module, etc., and there is no specific limitation.

[0061] Furthermore, a limiting portion 41 is provided on the moving member 4, and is used to contact and abut against the support surface 21 when the moving member 4 moves downward relative to the connecting member 3 by a certain distance after leaving the support surface 21. The design of the limiting portion 41 can limit the downward displacement of the moving member 4 after the stopper 2 leaves the support surface 21, so as to prevent the moving member 4 from directly detaching from the connecting member 3, resulting in the failure of the subsequent stopper cooperation. The limitation of the downward movement distance, that is, the specific distance limitation of the downward movement can be designed according to actual needs, and there is no specific limitation.

[0062] Regarding the setting position of the limiting portion 41, it can be provided on the portion where the movable member 4 penetrates downward through the connecting member 3. When one end of the movable member 4 that penetrates downward through the connecting member 3 leaves the supporting surface 21, the movable member 4 can move downward until the limiting portion 41 contacts and abuts against the supporting surface 21. Of course, it can also be provided on the portion where the movable member 4 penetrates upward through the connecting member 3, and no specific limitation is made.

[0063] Further, taking the above-mentioned limiting portion 41 provided on the portion where the movable member 4 penetrates downward through the connecting member 3 as an example, a magnetic attracting member 31 can be provided on the connecting member 3 and / or the limiting portion 41, and the limiting portion 41 can be magnetically coupled with the connecting member 3 through the magnetic attracting member 31. It can be understood that when only one of the connecting member 3 and the limiting portion 41 is provided with the magnetic attracting member 31, at least a part of the other structure needs to be provided with a material layer that can be magnetically attracted by the magnetic attracting member, such as iron; in the present application, the magnetic attracting member 31 is provided at the bottom of the connecting member 3, and the whole limiting portion 41 can be magnetically coupled with the magnetic attracting member 31. Under this design, when it is necessary to control the linear displacement driver 1 to reset, the movable member 4 can be pulled upward until the limiting portion 41 is magnetically coupled with the magnetic attracting member 31, so that the movable member 4 can be located at a position higher than the supporting surface 21, without always holding the movable member 4 by hand, which is more convenient to use. When the linear displacement driver 1 is reset, that is, when the movable member 4 returns above the supporting surface 21 again, at this time, the movable member 4 can be pressed downward until the movable member 4 is separated from the magnetic attracting cooperation with the magnetic attracting member 31 and contacts the supporting surface 21 again, so as to ensure that when the movable member 4 moves away from the supporting surface 21 again, it can move downward normally.

[0064] Based on the above design, in order to further save operation and improve the convenience of use, a separating member 6 is further included.

[0065] The separating member 6 is installed on the stopper 2 and can be wedge-fitted with the limiting portion 41 for: during the process of the movable member 4 moving towards the stopper 2, by sliding relatively along the wedge-fitting position of the limiting portion 41 in a fitting manner, so that the limiting portion 41 moves in the direction of separating from the connecting member 3 to release the magnetic attraction cooperation with the magnetic attracting member 31. By using the wedge fit between the separating member 6 and the limiting portion 41, the horizontal movement of the limiting portion 41 relative to the separating member 6 can be converted into the vertical movement of the limiting portion 41, and then the limiting portion 41 and the magnetic attracting member 31 are separated to release the magnetic attraction between the limiting portion 41 and the magnetic attracting member 31, so that the magnetic attracting member 31 moves downward to contact the supporting surface 21. To satisfy the wedge fit between the separating member 6 and the limiting portion 41, it can be that both the limiting portion 41 and the separating member 6 are provided with guiding inclined surfaces. Of course, it can also be that a guiding arc surface is provided on the separating member 6 and a guiding inclined surface is provided on the limiting portion 41 to cooperate with it, and no specific limitation is made.

[0066] The limiting part 41 is a structural design that protrudes from the movable part 4 along the circumferential direction of the movable part 4. Specifically, the limiting part 41 can be a ring structure, that is, a convex ring structure, and is arranged around the movable part 4. Those skilled in the art can make appropriate design changes based on this, without limitation.

[0067] Taking the limiting part 41 as a convex ring structure design as an example, an inclined chamfer can be made on the edge of the top surface of the limiting part 41 to form a mating inclined surface 411 that can be used for wedge fit. The separating part 6 can be designed as a base block 61 and a separating part 62 in an inverted L shape arranged on the base. The lower edge of the end surface of the separating part 62 away from the base block 61 is provided with a mating arc surface 621 that can be in sliding contact with the mating inclined surface 411, so as to realize the wedge fit between the separating part 6 and the limiting part 41.

[0068] Furthermore, the magnetic attracting part 31 can be designed as an electromagnet, and the controller is electrically connected to the magnetic attracting part 31 and is used to control the magnetic attraction of the magnetic attracting part 31. By means of electric control, the magnetic attracting part 31 is controlled to generate magnetism or not generate magnetism or control the generated magnetic strength, so as to control the magnetic attraction fit between the magnetic attracting part 31 and the limiting part 41, and thus there is no need to set the separating part 6.

[0069] Furthermore, the movable part 4 can be designed as a pin. The pin can be selected to have a head structure, and the head structure can be used as the limiting part 41 to play a role in restricting the excessive downward movement of the movable part 4.

[0070] As Figure 4 shown, the present application also discloses a control method for the displacement driving mechanism. This control method is applied to the displacement driving mechanism in the second embodiment above with a controller, a sensing part 5, and the magnetic attracting part 31 being an electromagnet, and includes the following steps:

[0071] S1. The controller responds to the first control instruction and controls the driving end of the linear displacement driver to move so that the movable part moves towards the stop surface of the stop part until it leaves the support surface of the stop part.

[0072] S2. The controller responds to the signal fed back by the sensing part after sensing the movable part and controls the linear displacement driver to execute the operation locking mode.

[0073] S3. The controller responds to the second control instruction and controls the magnetic attracting part on the connecting part to generate magnetism to adsorb the limiting part on the movable part, so that the movable part is higher than the support surface.

[0074] S4. The controller responds to the third control instruction, controls the driving end of the linear displacement driver to reset, and when the driving end resets in place, controls the magnetic attracting part to eliminate magnetism to release the limiting part, so that the movable part contacts the support surface.

[0075] The above first control instruction, second control instruction, and third control instruction can all be triggered by a control panel connected to the linear displacement driver 1, without limitation.

[0076] As Figures 5 to 8 shown, the present application also discloses a cleaning device applied to pole piece cleaning, which includes two cleaning mechanisms 7.

[0077] The two cleaning mechanisms 7 are arranged at intervals and a cleaning passage for the object to be cleaned to pass through is formed therebetween, that is, a pole piece cleaning passage for the pole piece substrate to pass through is formed.

[0078] At least one of the two cleaning mechanisms 7 is adjustably displaceably arranged by the displacement driving mechanism of the above-mentioned Embodiment 1 or Embodiment 2, so that the width of the cleaning passage is adjustable. It can be understood that at least one of the two cleaning mechanisms 7 is connected to the displacement driving mechanism of the aforementioned Embodiment 1 or Embodiment 2, so that the cleaning mechanism 7 is adjustable.

[0079] Specifically, the linear displacement driver 1 in the displacement driving mechanism can be installed on the stop member 2, and the driving end of the linear displacement driver 1 is connected to the corresponding cleaning mechanism 7 to facilitate driving the cleaning mechanism 7 to move. The stop member 2 can be designed to fit the cleaning mechanism 7 to better support and fix the linear displacement driver 1 and the cleaning mechanism 7, and at the same time achieve the safety stop function. That is, in the pole piece cleaning device, the stop member 2 can replace the bracket for supporting and fixing the cleaning mechanism 7 in the existing pole piece cleaning device, or directly use the bracket as the stop member 2, without specific limitation.

[0080] In order to achieve high-efficiency control, the present application preferably both cleaning mechanisms 7 are connected to the displacement driving mechanism with the above-mentioned design improvements.

[0081] The connecting member 3 in the displacement driving mechanism is installed on the cleaning mechanism 7, and the linear displacement driver 1 drives the cleaning mechanism 7 to move, so as to drive the connecting member 3 to move synchronously.

[0082] The stop surface 22 of the stop member 2 is used to stop the adjustably displaceably arranged cleaning mechanism 7 from moving in the direction of reducing the width of the cleaning passage, so as to avoid the situation that the distance between the two cleaning mechanisms 7 is reduced due to the failure of the linear displacement driver 1 or accidental touch of the control button of the linear displacement driver 1, resulting in injury to the staff or the pole piece.

[0083] In the present application, the cleaning mechanism 7 can be designed with reference to the cleaning module in the existing pole piece cleaning device or directly used, for example, including an outer cover 72, a brush 73 pivotally connected inside the outer cover 72, a negative pressure chamber 74 connected to the bottom of the outer cover 72, and a motor 71 for driving the brush 73 to rotate, which will not be elaborated here.

[0084] The displacement driving mechanism of this design in this application is not only applied in the field of pole piece cleaning, but also can be applied to, for example, opening and closing door control, etc., without specific limitation.

[0085] This application also discloses a pole piece cleaning device, including the improved cleaning device described above, and the cleaning channel of the cleaning device is for the pole piece substrate to pass through. The pole piece cutting device is used to perform die cutting on the pole piece substrate to form pole ears, or perform slitting on the pole piece substrate to slit one pole piece substrate into multiple pole pieces.

[0086] The displacement driving mechanism, control method, cleaning device and pole piece cutting device provided in this application have been introduced in detail above. For those of ordinary skill in the art, according to the idea of the embodiments of this application, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to this application.
