Description

Technical Field

[0001] This utility model relates to the field of burr removal technology, specifically to a copper bar burr removal device. Background Technology

[0002] Copper bars are conductive materials used for connecting battery modules and circuit boards. They are typically made of copper foil and are often simply called copper bars. Copper bars are flexible connectors primarily used for electrical connections between battery modules and circuit boards. In the battery modules of new energy vehicles, each battery needs to be electrically connected to the circuit board via a copper bar to achieve charging or discharging functions. Copper bars are widely used in high-current equipment in fields such as power grids, rail transportation, communications, military, and aerospace.

[0003] For example, in actual operation, the vibratory polishing machine relies on vibration to make the polishing abrasive media interact with the workpiece, which makes it difficult to ensure that every part of every workpiece is polished evenly. This is especially true for copper workpieces with complex shapes, grooves, or dead corners, which can lead to uneven polishing results. Therefore, a copper burr removal device is used.

[0060] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0061] like Figures 1 to 12As shown, a copper burr polishing device includes: a base 1, a control switch 2, and multiple supports 3 fixedly installed on the top. A strong spring 4 is provided above the support 3, and a polishing disc 5 is fixedly installed above the multiple strong springs 4. The device also includes: a vibrating rod 6 fixedly installed in the center of the polishing disc 5, a drive motor 7 is provided inside the vibrating rod 6, and the drive end of the drive motor 7 passes through the polishing disc 5 and the vibrating rod 6.

[0062] The grinding section is located inside the polishing disc 5 to grind the copper workpiece;

[0063] The polishing part includes an adjusting member and a repositioning member. The adjusting member is located above the drive motor 7 and outside the drive motor 7. The adjusting member is connected to the repositioning member, and the lower part of the repositioning member contacts the inner wall of the polishing disc 5.

[0064] The agitator is located on the outside of the vibrating rod 6 to agitate the polishing abrasive.

[0065] The flipping part includes a driving component and a spreading component. The spreading component is located on the outside of the vibrating rod 6 and on the inner wall of the polishing disc 5. The repositioning component is connected to the spreading component through the driving component.

[0066] When working, when polishing the burrs on the copper bar, using the preferred embodiment of this utility model, firstly, polishing abrasive is added to the polishing disc 5, then the copper bar workpiece is added to the polishing disc 5, and the control switch 2 is activated to make the drive motor 7 rotate to generate a deflection force. The deflection of the drive motor 7 transmits the force to the upper vibrating rod 6, and the drive motor 7 drives the vibrating rod 6 to vibrate. The support 3 and the strong spring 4 play an auxiliary role in the rear vibration buffer. The vibrating rod 6 is linked to the vibration of the polishing disc 5, and the polishing abrasive medium in the polishing disc 5 moves to all sides with the vibration. After the polishing abrasive vibrates, it interacts with the copper bar workpiece. Through the continuous movement of the polishing abrasive and friction with the copper bar workpiece, the burrs on the surface of the copper bar workpiece are polished away.

[0067] Because copper workpieces have complex shapes, grooves, or dead corners, the polishing medium may have difficulty reaching these areas, resulting in inconsistent polishing effects. Therefore, when the drive motor 7 rotates, it drives the repositioning component to move synchronously. The repositioning component rotates along the inner wall of the polishing disc 5, changing the position of the copper workpiece placed in the polishing sand in the polishing disc 5. This makes the dead corners or grooves easier to polish, facilitating the polishing of areas that were previously inaccessible to the grooves or dead corners. In addition, the burrs contain both ferromagnetic and non-ferromagnetic materials. The repositioning component is magnetic, and when it rotates, it will attract the ferromagnetic material on the surface of the copper workpiece, thereby reducing the presence of some ferromagnetic burrs and reducing the difficulty of surface polishing. It should be noted that the repositioning component has a strong attraction force, and after attracting burrs containing ferromagnetic material, it will not be obstructed by the polishing sand during rotation and fall off.

[0068] However, the angle of the repositioning component cannot be adjusted when it rotates, and it only rotates in one direction, making it difficult to grind the copper workpieces in other positions. Therefore, after the drive motor 7 rotates, the angle adjustment component works in conjunction with it. Each time the angle adjustment component rotates, it gradually retracts a certain distance inward. After retraction, the repositioning component moves from the outside to the side closer to the vibrating rod 6, so as to change the position of the copper workpieces at different angles, thereby promoting the effect of comprehensive grinding and improving uniformity.

[0069] Furthermore, when the repositioning component moves toward the vibrating rod 6, it will come into contact with the driving component. The driving component will push the spreading component inward, causing it to be squeezed and flipped. The spreading component will then form a tendency to push outward on the outer surface of the vibrating rod 6, which will facilitate the adjustment of the position of the copper workpiece and the polishing sand.

[0070] The corner adjustment components include:

[0071] The mounting plate 71 is positioned above the drive motor 7 and located outside the drive motor 7;

[0072] The mounting base 72 is fixedly installed at one end of the drive motor 7 and is located above the mounting plate 71;

[0073] The processor 73 is located on one side of the mounting plate 71;

[0074] The corner adjustment component also includes:

[0075] The first electric lever 74 is located on one side of the processor 73;

[0076] A magnetic chuck 75 is fixedly installed at the end of the first electric rod 74;

[0077] A rotating shaft 76 is rotatably mounted on the lower surface of the fixed base 72, and the rotating shaft 76 passes through the fixed base 72;

[0078] The core rod 77 is located on the outer surface of the rotating shaft 76 and is magnetically connected to the magnetic chuck 75.

[0079] like Figures 3 to 5 , Figures 8 to 9During operation, it is generally difficult to ensure that every part of every copper workpiece is polished evenly. For copper workpieces with complex shapes, grooves, or dead corners, the polishing abrasive may not be able to fully reach these parts, resulting in inconsistent polishing effects. When it is necessary to change the position of the copper workpiece for uniform polishing, the preferred embodiment of this utility model is used. The drive motor 7 rotates in conjunction with the mounting plate 71 and the processor 73. The processor 73 transmits the rotational electrical signal to the first electric rod 74. The magnetic chuck 75 at one end of the first electric rod 74 attracts the core rod 77. After the first electric rod 74 rotates, it first drives the core rod 77 to rotate one revolution. After the core rod 77 rotates one revolution, it will retract inward once. Each revolution of the first electric rod 74 pulls the core rod 77 to move inward once. Through the movement, the copper workpiece and the polishing abrasive come into frictional contact. The core rod 77 pulls the workpiece from the outside towards the vibrating rod 6, adjusting the copper workpieces in various positions to ensure that the polishing abrasive can rub against the dead corners, improving the uniform polishing effect.

[0080] The repositioning components include:

[0081] The limiting seat 773 is located at one end of the core rod 77;

[0082] Linkage bar 774 is set on one side of limit seat 773, and the height of linkage bar 774 is less than the height of limit seat 773;

[0083] The repositioning component also includes:

[0084] Sandpaper 775 is installed inside the linkage bar 774, and sandpaper 775 is L-shaped with one side penetrating the limiting seat 773;

[0085] Two plug-in strips 776 are provided, which pass through the linkage strip 774 and are slidably connected to the inner side of the linkage strip 774;

[0086] Connecting strip 777 is fixedly installed on the outside of plug strip 776;

[0087] like Figures 8 to 9 As shown, when uniform polishing is required, using this embodiment of the invention, the core rod 77 rotates to drive the limiting seat 773 to rotate. The rotating limiting seat 773 gradually moves the polishing abrasive, accelerating the movement of the polishing abrasive and promoting contact between the polishing abrasive and the copper workpiece. At the same time, as the first electric rod 74 retracts, it pulls the limiting seat 773 towards the vibrating rod 6, and the linkage bar 774 moves accordingly. The linkage bar 774 rotates and moves inward while squeezing the polishing abrasive and the copper workpiece, changing the dead corner position of the copper workpiece, accelerating the polishing abrasive and grinding the dead corner position, thereby promoting uniform polishing.

[0088] The repositioning component also includes:

[0089] The second electric pole 778 is installed at one end of the connecting bar 777;

[0090] Position sensor 779 is fixedly installed at one end of the second electric pole 778.

[0091] The limiting seat 773 has a through groove on the side near the linkage bar 774.

[0092] The repositioning component also includes:

[0093] The insert strip 776 is fixedly connected to both sides of the sandpaper 775;

[0094] Connecting strip 777 passes through the interior of limiting seat 773 and connects to plug strip 776.

[0095] like Figures 11 to 12 As shown, common polishing abrasives come in various shapes, such as round and angular. Some angular polishing abrasives often cause scratches when they come into contact with and rub against the copper workpiece. In the preferred embodiment of this utility model, when the linkage bar 774 moves in the direction of the vibrating rod 6, the linkage bar 774 comes into contact with the polishing abrasive and the copper workpiece. A small amount of polishing abrasive enters the interior of the linkage bar 774, causing the sandpaper 775 to come into contact with a portion of the polishing abrasive. When the sandpaper 775 comes into contact with the polishing abrasive, friction is generated, which accelerates the flattening of the angular abrasive shape and prevents some polishing abrasive from causing scratches on the copper workpiece due to friction caused by its shape, thereby improving the polishing accuracy.

[0096] During use, polishing abrasive gradually fills the interior of the linkage bar 774, preventing further entry of polishing abrasive and hindering polishing. In this embodiment, when the polishing abrasive fills the interior of the linkage bar 774 and is flush with its upper surface, the position sensor 779 senses the positional relationship between the polishing abrasive and the linkage bar 774. The second electric rod 778 is then energized and extended, pressing the connecting bar 777 to move. The connecting bar 777 pushes the sandpaper 775 towards the vibrating rod 6 by pushing the insertion strip 776. After the sandpaper 775 is inserted into the linkage bar 774, the polishing abrasive overflows into the polishing disc 5 due to the pushing and squeezing action, thus ensuring that the linkage bar 774 has the effect of reloading polishing abrasive a second time.

[0097] The driving components include:

[0098] The folding rod 770 has one end set on the inner surface of the limiting seat 773 and the other end set on the outer side of the vibrating rod 6;

[0099] A magnetic locking plate 771 is fixedly installed at one end of the folding rod 770.

[0100] The drive unit also includes:

[0101] The folding rod 770 passes through the interior of the limiting seat 773, and the magnetic locking plate 771 is located on the outside of the flipping collar 63 and contacts the lever 64.

[0102] like Figure 8 As shown, when it is necessary to connect the limiting seat 773 and the rotating rod 61 to improve the grinding speed, using the preferred embodiment of this utility model, when the limiting seat 773 moves inward, it will drive the folding rod 770 and the magnetic locking plate 771 to move. The folding rod 770 is in a straight and unretracted state by default. After the magnetic locking plate 771 moves, it attracts the spreading part to form a combination. At this time, the limiting seat 773 continues to move inward, and the limiting seat 773 squeezes the folding rod 770 to move. After the folding rod 770 moves, it is collected at the magnetic locking plate 771. At this time, the weight on the magnetic locking plate 771 increases, and the direction of the force is downward. After the magnetic locking plate 771 is combined, it twists with the accumulation of gravity. Through twisting, the spreading part is gradually unfolded, thereby having a driving effect, which facilitates the indication of driving force for the unfolding of the spreading surface.

[0103] Amortized components include:

[0104] Rotating rod 61 is installed on the inner wall of vibrating rod 6;

[0105] The push plate 62 is rotatably disposed on the outside of the rotating rod 61, and there are multiple of them, which are U-shaped;

[0106] The flip-ring 63 is fixedly installed on the outside of the rotating rod 61;

[0107] The inner wall of the push plate 62 is rotated relative to the inner wall of the polishing disc 5.

[0108] like Figures 6 to 7As shown, when it is necessary to accelerate the vibration of the polishing sand on the outside of the vibrating rod 6, the polishing sand needs to move and contact the copper workpiece to complete the grinding. However, the speed at which the polishing sand moves by vibration alone is slow, and the friction efficiency is low, resulting in slow work efficiency. Therefore, in the preferred embodiment of this utility model, the limiting seat 773 moves towards the vibrating rod 6. The limiting seat 773 pushes the magnetic locking plate 771 and the folding rod 770 to move. The magnetic locking plate 771 first contacts the flipping collar 63. The flipping collar 63 and the magnetic locking plate 771 have opposite magnetic properties, and the two attract each other. At this time, the limiting seat 773 continues to move towards the vibrating rod 6. The limiting seat 773 pushes the folding rod 770 to move, and the folding rod 770 moves away from the vibrating rod 6. The weight is applied to the magnetic locking plate 771, causing it to twist. The flipping collar 63 is also twisted synchronously by the magnetic locking plate 771. When the flipping collar 63 twists, it drives the rotating rod 61 to rotate. The rotating rod 61 rotates at a certain angle, pushing the plate 62 outward, thereby accelerating the movement of the polishing sand on the outside and increasing the friction intensity of the polishing. It should be noted that the limiting seat 773 is set in an inclined shape. The limiting seat 773 pushes the folding rod 770 and the magnetic locking plate 771 with a tendency to apply force from the upper side to the lower side. At the same time, the flipping collar 63 is the negative pole, while the magnetism of the magnetic locking plate 771 is the positive pole. The two are set to a mother-and-child bayonet engagement method.

[0109] Working Principle: The working principle of this copper bar burr grinding device revolves around core components such as the base 1, control switch 2, support 3, strong spring 4, polishing disc 5, vibrating rod 6, drive motor 7, grinding section, and flipping section. Through the coordinated operation of these components, efficient grinding of burrs on copper bar workpieces is achieved, as detailed below:

[0110] Before starting the device, polishing abrasive is added to the polishing disc 5, and then the copper workpiece to be polished is placed inside the polishing disc 5. After activating the control switch 2, the drive motor 7 begins to rotate, generating a deflection force that is transmitted to the vibrating rod 6 above, causing the vibrating rod 6 to vibrate. At this time, the support 3 and the strong spring 4 fixedly installed on the top of the base 1 play a role in providing vibration buffering and ensuring a smooth vibration process. The vibration of the vibrating rod 6 further links the vibration of the polishing disc 5, causing the polishing abrasive medium inside the polishing disc 5 to move outwards with the vibration. During this process, the polishing abrasive interacts with the copper workpiece, and through continuous movement and friction, gradually removes the burrs from the surface of the copper workpiece.

[0111] However, due to the complex shape of copper workpieces, including grooves and dead corners, ordinary vibration grinding may result in the polishing medium failing to reach these areas sufficiently, leading to inconsistent polishing effects. Therefore, the device is designed with a grinding section for targeted treatment. When the drive motor 7 rotates, it drives the repositioning component to move synchronously. The repositioning component rotates along the inner wall of the polishing disc 5, changing the position of the copper workpiece within the disc 5. This adjusts areas that were originally in grooves or dead corners to easier-to-grind locations, facilitating the treatment of these difficult-to-grind areas. Furthermore, the repositioning component is magnetic, capable of attracting ferromagnetic burrs on the surface of the copper workpiece, reducing the presence of ferromagnetic burrs and simplifying post-grinding cleaning. Its strong attraction also ensures that the attracted burrs will not fall off due to the rotation of the polishing abrasive.

[0112] However, the repositioning component rotates at a fixed angle, only in one direction, which is not conducive to grinding copper workpieces in other positions. At this time, the drive motor 7 rotates and activates the angle adjustment component. The mounting plate 71 and processor 73 in the angle adjustment component rotate in conjunction with the drive motor 7. The processor 73 transmits the rotational electrical signal to the first electric rod 74, and the magnetic chuck 75 at the end of the first electric rod 74 attracts the core rod 77. Each rotation of the first electric rod 74 pulls the core rod 77 inward once, causing the repositioning component to move from the outside towards the vibrating rod, thereby changing the position of copper workpieces at different angles, promoting comprehensive grinding, and improving the uniformity of grinding.

[0113] During the movement of the repositioning component towards the vibrating rod 6, the flipping section is triggered. When the limiting seat 773 in the repositioning component moves inward, it drives the folding rod 770 and the magnetic locking plate to move. The folding rod 770 is straight by default. After the magnetic locking plate moves, it attracts and engages with the flipping collar 63 in the spreading component (the two have opposite magnetic properties and use a mother-daughter bayonet engagement method). The limiting seat 773 continues to move and compress the folding rod 770, causing it to retract at the magnetic locking plate. As the weight accumulates, the magnetic locking plate twists, causing the flipping collar 63 to twist synchronously. When the flipping collar 63 twists, it drives the rotating rod 61 to rotate. The rotating rod 61 rotates at a certain angle, pushing the plate 62 outward, accelerating the movement of the polishing sand on the outside, enhancing the friction intensity of grinding, and improving grinding efficiency.

[0114] Furthermore, the device also has corresponding handling mechanisms to address potential problems with the polishing abrasive. Some angular polishing abrasive particles can easily cause scratches when they come into contact with the copper workpiece. When the linkage bar 774 moves towards the vibrating rod and comes into contact with the polishing abrasive and the copper workpiece, a small amount of polishing abrasive enters the interior of the linkage bar 774. The abrasive paperboard 775 then comes into contact with and rubs against the polishing abrasive, smoothing out the angular shape of the abrasive particles, preventing scratches, and improving polishing accuracy. When the polishing abrasive fills the interior of the linkage bar 774, the position sensor 779 senses the positional relationship between the polishing abrasive and the linkage bar 774, activating the second electric rod 778. The second electric rod 778 extends and presses the connecting strip 777, pushing the abrasive paperboard 775 through the insertion strip 776, causing the polishing abrasive to overflow into the polishing disc 5. This ensures that the interior of the linkage bar 774 can be reloaded with polishing abrasive, maintaining the continuous polishing operation.
