Abstract
Description
Technical Field
[0001] The invention relates to the field of lithium battery negative electrodes, and in particular to a special positioning device for three-eccentric mixing equipment of a lithium battery negative electrode production line. Background Art
[0002] This application is mainly designed for the three-eccentric mixing equipment of the lithium battery negative electrode production line. The barrel of the hopper of the three-eccentric mixing equipment of the lithium battery negative electrode production line is connected to the rotating shaft. Its main material port first receives materials from the discharge port of the equipment in the previous process, and then the rotating shaft drives the barrel to rotate, and the main material port moves to the inlet of the equipment in the next process to transport materials. However, the discharge port of the hopper often cannot be accurately moved to the standard position during docking, causing the entire production line to be unable to run smoothly. There are various reasons for this situation. For example, the amount of material received by the hopper each time is different, but the torque output on the motor is a fixed value. For example, after the equipment has been used for a period of time and depreciated, the rotation amplitude of the shaft will more or less deviate. Summary of the invention
[0003] In order to solve the technical problem that the discharge port of the hopper of the existing three-eccentric mixing equipment of the lithium battery negative electrode production line cannot be accurately moved to the standard position during docking, the present invention provides a special positioning device for the three-eccentric mixing equipment of the lithium battery negative electrode production line, which solves the above technical problem.
[0004] The technical solution adopted by the present invention to solve its technical problem is:
[0005] The present invention provides a special positioning device for a three-eccentric mixer of a lithium battery negative electrode production line, comprising: a positioning guide groove, which is formed on a rotating shaft of the three-eccentric mixer of the lithium battery negative electrode production line, and the positioning guide groove extends along the radial direction of the rotating shaft, and the groove transition section of the positioning guide groove gradually widens from a positioning end close to the center of the rotating shaft to a guide end far from the center of the rotating shaft; an introduction member, which has a clearance fit with the guide end of the positioning guide groove, and the introduction member has a transition fit with the positioning end of the positioning guide groove, and after the transfer hopper stops rotating, the introduction member enters the guide end of the positioning guide groove from the radial direction of the rotating shaft, and then the introduction member moves to the positioning end, and drives the transfer hopper to move to a standard position through the rotating shaft.
[0006] Furthermore, the positioning guide groove is arranged on the rotating shaft through a positioning plate, the positioning plate is coaxially fixedly connected to the rotating shaft, and the positioning guide groove is formed on the outer circumference of the plate body of the positioning plate.
[0007] Furthermore, the positioning plate is a flange inherent in the rotating shaft.
[0008] Furthermore, the flange is a connecting flange on a coupling connected to the rotating shaft.
[0009] Furthermore, it also includes a driving module for driving the introduction member to move, the driving module includes a driving cylinder, the cylinder body of the driving cylinder is fixedly configured, and the piston of the driving cylinder is connected to the introduction member.
[0010] Furthermore, the driving module also includes a guide assembly, which includes a fixed guide groove and a slider slidably engaged with the guide groove, the guide groove extends along the radial direction of the rotating shaft, and the guide piece is connected to the slider.
[0011] Further, the positioning member is a cylindrical roller rotatably matched on the slider, and correspondingly, the port of the positioning end is formed into a semicircular port adapted to the shape of the cylindrical roller.
[0012] Furthermore, the driving cylinder is a pneumatic cylinder.
[0013] Furthermore, the included angle between two groove edges of the positioning guide groove is less than or equal to 40 degrees.
[0014] Based on the above technical solution, the technical effects that can be achieved by the present invention are:
[0015] The special positioning device for the three-eccentric mixing equipment of the lithium battery negative electrode production line of the present application has a positioning guide groove formed on the rotating shaft of the transfer hopper, and the guide piece enters the guide end of the positioning guide groove from the radial direction of the rotating shaft, and then the guide piece moves to the positioning end, and drives the transfer hopper to move to the standard position through the rotating shaft. Specifically, the rotating shaft is first driven by a motor, and the rotating shaft drives the transfer hopper to move to the initial position for receiving or conveying materials. There is a certain angle deviation between the initial position and the actual standard position. To be more specific, when the rotation angle of the rotating shaft is less than 5° from the design angle, the transfer hopper can operate normally, but in fact, the rotation angle of the rotating shaft is often greater than 5° from the design angle. When the transfer hopper stops at the initial position, the guide piece enters the positioning guide groove and drives the rotating shaft to move, repairing the deviation of the actual rotation angle of the rotating shaft, thereby positioning the transfer hopper to the standard position. In summary, the present application realizes multi-angle positioning of the hopper, and solves the technical problem that the discharge port of the hopper of the existing three-eccentric mixing equipment of the lithium battery negative electrode production line cannot be accurately moved to the standard position during docking.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0021] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0023] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0024] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0025] like Figure 1-2 As shown, the present application provides a special positioning device for a three-eccentric mixing equipment of a lithium battery negative electrode production line, including a positioning guide groove 1 and an introduction piece 2. The positioning guide groove 1 is formed on a rotating shaft b that drives a hopper a to rotate, and the positioning guide groove 1 extends radially along the rotating shaft b. The groove transition section of the positioning guide groove 1 gradually widens from a positioning end 11 close to the center of the rotating shaft b to a guide end 12 away from the center of the rotating shaft b. The introduction piece 2 is clearance-matched with the guide end 12 of the positioning guide groove 1, and the introduction piece 2 is transitionally matched with the positioning end 11 of the positioning guide groove 1. After the hopper a stops rotating, the introduction piece 2 enters the guide end 12 of the positioning guide groove 1 from the radial direction of the rotating shaft b, and then the introduction piece 2 moves to the positioning end 11 and drives the hopper a to move to the standard position through the rotating shaft b.
[0026] The special positioning device for the three-eccentric mixing equipment of the lithium battery negative electrode production line of the present application has a positioning guide groove 1 formed on the rotating shaft b of the hopper a, and the guide piece 2 enters the guide end 12 of the positioning guide groove 1 from the radial direction of the rotating shaft b, and then the guide piece 2 moves to the positioning end 11, and drives the hopper a to move to the standard position through the rotating shaft b. Specifically, the rotating shaft b is first driven by a motor, and the rotating shaft b drives the hopper a to move to the initial position for receiving or conveying materials. There is a certain angle deviation between the initial position and the actual standard position. To be more specific, when the rotation angle of the rotating shaft b is less than 5° from the design angle, the hopper a can operate normally, but in fact the rotation angle of the rotating shaft b is often greater than 5° from the design angle. When the hopper a stops at the initial position, the guide piece 2 enters the positioning guide groove 1 and drives the rotating shaft b to move, repairing the deviation of the actual rotation angle of the rotating shaft b, thereby positioning the hopper a to the standard position. In summary, the present application realizes multi-angle positioning of hopper a, and solves the technical problem that the discharge port of hopper a of the existing three-eccentric mixing equipment of lithium battery negative electrode production line cannot be accurately moved to the standard position during docking.
[0027] Furthermore, the positioning guide groove 1 is configured on the rotating shaft b through the positioning plate 3 , the positioning plate 3 is coaxially fixedly connected with the rotating shaft b, and the positioning guide groove 1 is formed on the outer periphery of the plate body of the positioning plate 3 .
[0028] In an optional solution of the present application, the positioning plate 3 is coaxially fixedly connected to the inherent flange plate on the rotating shaft b. In this way, only another positioning plate 3 needs to be processed and connected to the inherent flange plate on the rotating shaft b by bolts, which is convenient for secondary transformation of old equipment.
[0029] Alternatively, in another embodiment of the present application, the positioning plate 3 is a flange inherent in the rotating shaft b. Further, the flange inherent in the rotating shaft b can be selected as a connecting flange on a coupling c connected to the rotating shaft b.
[0030] Specifically, the special positioning device for the three-eccentric mixing equipment of the lithium battery negative electrode production line of the present application also includes a driving module for driving the introduction piece 2 to move, and the driving module includes a driving cylinder 5, which can be optionally a cylinder. The cylinder body of the driving cylinder 5 is fixedly configured, and the piston of the driving cylinder 5 is connected to the introduction piece 2.
[0031] Furthermore, the driving module also includes a guide assembly, which includes a fixed guide groove and a slider 4 slidably engaged with the guide groove, the guide groove extends along the radial direction of the rotating shaft b, and the guide member 2 is connected to the slider 4.
[0032] Preferably, the positioning member is a cylindrical roller rotatably fitted on the slider 4, and correspondingly, the port of the positioning end 11 is formed as a semicircular opening adapted to the shape of the cylindrical roller.
[0033] In a preferred embodiment of the present application, the included angle between two groove edges of the positioning guide groove is less than or equal to 40 degrees.
[0034] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
