Description

Technical Field

[0001] The utility model relates to lead terminal production equipment, in particular to a lead terminal burr removal machine. Background Art

[0002] Lead terminals are important accessories for lead-acid batteries, which usually include a connecting portion, a wiring portion, and a torque ring integrally connected between the connecting portion and the wiring portion. A patent document with announcement number CN209658291U discloses an anti-rotation battery terminal. The anti-rotation battery terminal provided in the embodiment includes a hollow cylinder and a toothed ring integrally connected to the outer wall of the hollow cylinder, wherein the hollow cylinder is a rotating body made of lead material, and one or more convex rings are integrally connected to the outer wall of the hollow cylinder, the radial semi-section (i.e., the section in the radial direction) of the convex ring is arrow-shaped, and the arrow-shaped portion of the convex ring is an inverted hook structure; the toothed ring is coaxially arranged with the hollow cylinder, and a plurality of anti-rotation teeth are evenly arranged around the axis of the hollow cylinder, and a tooth groove is formed between two adjacent anti-rotation teeth, and the tooth groove portion is a concave arc surface structure.

[0003] At present, lead terminals are generally obtained by cold forging and stamping. Since the blanks obtained after cold forging and stamping have relatively low dimensional accuracy and inevitably have burrs, it is necessary to further remove the burrs on their surfaces. Existing deburring equipment can usually only deburr and polish a fixed angle or surface, that is, the angle at which the bristles contact the workpiece is often fixed, and the burr removal effect is affected by the angle at which the bristles contact the burrs. Therefore, the use of existing deburring equipment has certain limitations; for the curved surface part, especially the undercut part, the use of existing equipment has certain limitations. Usually, workers need to hold the workpiece by hand and adjust the angle of the workpiece to the deburring equipment. The operation is unsafe and inefficient, and it may even be impossible to polish it clean and require manual secondary polishing with sandpaper. The existing equipment has a poor deburring effect.

[0004] In view of this, the applicant conducted an in-depth study on the above issues, which led to the present case. Utility Model Content

The angle between the first and second rays is called the brush penetration angle, and the brush penetration angle has an angle value of 30° to 60°. Furthermore, the brush penetration angles in each brush assembly 340 have different values.

[0048] It should be noted that the first ray and the second ray are both lines that do not actually exist, and are introduced to better describe the relative positions of the brush member 341 and the wheel disc 310 .

[0049] By setting up multiple brush groups 340 with different brush cutting angles, in the process of removing burrs on the surface of the lead terminal 999, different brush groups 340 have different initial contact angles at the same position on the surface of the lead terminal 999, which is beneficial to avoiding the problem that the burrs on the surface of the lead terminal 999 are difficult to remove due to a single angle, and the removal effect is good.

[0050] One end of each rotating column 343 has an external thread section, and the other end is fixed with a column cap, and each brush member 341 is located between the corresponding column cap and the wheel disc 310. Specifically, in the same brush group 340, the column cap is cylindrical, and the column cap and the rotating column 343 are coaxially arranged.

The rotating post 343 is screwed to the wheel disc 310, which makes it easy to remove the rotating post 343 from the wheel disc 310, thereby facilitating the replacement of the brush member 341 and facilitating the maintenance of the brush member 341 of the brush assembly 340 during subsequent use.

[0051] Furthermore, each elastic adjustment member 342 is a tension spring, one end of each tension spring is fixed to one end of the corresponding brush member 341 close to the axis of the wheel disc 310, and the other end is fixed to the wheel disc 310; in the same brush group 340, the tension spring and the bristles are respectively located on both sides of the brush member 341.

[0052] Furthermore, the rotating brush group 300 also includes a second base 350 and a second cylinder 360 for driving the second base 350 to move, the second cylinder 360 is fixed to the motor frame 320, and the second base 350 is slidably connected to the motor frame 320.

[0053] By fixing the second motor 330 to the second base 350 and using the second cylinder 360 to drive the second base 350 to move on the motor frame 320, it is helpful to adjust the distance between the wheel 310 and the mounting part 211, and indirectly adjust the distance between the brush part 341 on the wheel 310 and the lead terminal 999.

[0054] The pressing group 400 includes a pressing seat 410, a pressing cylinder 420 for driving the pressing seat 410 to move, and a mounting bracket 430 fixed to the workbench panel 100; the pressing seat 410 is located directly above the mounting member 211 and is slidably connected to the mounting bracket 430. Specifically, a vertical guide rail is fixed to the mounting bracket 430, and a vertical slide matching the vertical guide rail is provided on the pressing seat 410. The vertical slide of the pressing seat 410 is slidably connected to the vertical guide rail on the mounting member 211; The air cylinder 420 is located directly above the pressure seat 410 and is fixed to the mounting bracket 430. The piston rod of the pressure cylinder 420 is fixed to the pressure seat 410. The end of the pressure seat 410 away from the pressure cylinder 420 is rotatably connected to the rotating head 411. Specifically, a cylindrical groove is provided at the end of the pressure seat 410 away from the pressure cylinder 420. The rotating head 411 is rotatably connected to the cylindrical groove through multiple bearings. The rotating head 411 is indirectly rotatably connected to the pressure seat 410 by being rotatably connected to the cylindrical groove.

[0055] Furthermore, a protective cover 110 is secured to the upper end surface of the work surface 100. Together, the protective cover 110 and the work surface 100 form a working chamber, within which the mounting member 211 and the rotating brush assembly 300 are located. By providing the protective cover 110 on the work surface 100 and positioning the mounting member 211 and the rotating brush assembly 300 within the working chamber enclosed by the protective cover 110 and the work surface 100, burrs removed from the lead terminal 999 are trapped within the working chamber, preventing them from flying out and impacting the environment.

[0056] Furthermore, one end of the protective cover 110 is the working end, and the other end is the dust removal end. The working end is provided with a working port 111, and the mounting part 211 is located on the side close to the working end. The dust removal end is provided with a dust removal port 112, and the dust removal port 112 is a reserved interface for the fan. By providing the dust removal port 112 on the protective cover 110, it is convenient to connect the existing negative pressure fan to remove burrs in subsequent operations. During the brushing operation, the existing negative pressure fan is connected to the dust removal port 112 through the air duct, and then the negative pressure fan is started to suck out the burrs brushed off by the brush group 340 in the working chamber, thereby avoiding excessive accumulation of burrs in the working chamber. It should be noted that the negative pressure fan and the air duct are not components of the present invention. They are only used as supporting facilities in the present invention to illustrate the advantages of the present invention. The air duct and the negative pressure fan are not shown in the accompanying drawings.

[0057] During use, the lead terminal 999 to be deburred is manually or mechanically held through the working port 111 of the working chamber and installed on the mounting part 111, and then the pressing cylinder 420 of the pressing group 400 drives the pressing seat 410 to move toward the mounting part 111 until the rotating head 411 presses the upper position of the lead terminal 999; then the first motor 220 drives the first rotating shaft 210 to rotate, thereby rotating the lead terminal 999; the second motor 330 is turned on to drive the wheel 310 to rotate, thereby rotating the brush group 340 on the wheel 310 with the axis of the wheel 310 as the center; then the second cylinder 360 of the rotating brush group 300 drives the second base 350 to move, so that the brush group 340 can brush the lead terminal 999, and the bristles rotate and brush the surface of the lead terminal 999.

[0058] The burrs are removed by the combined action of the first motor 220 driving the lead terminal 999 to rotate and the brush group 340 with the elastic adjustment member 342 brushing the lead terminal 999 during rotation. During the brushing operation, the angle value of the brush cut-in angle of the brush in the brush group 340 gradually changes from when the brush member 341 initially contacts the lead terminal 999 to when the brush member 341 leaves the lead terminal 999, so that the brush member 341 can brush the burrs on the surface of the lead terminal 999 from different angles, avoiding the disadvantage that individual burrs are difficult to remove at a single angle, thereby achieving effective burr removal. The purpose of deburring is to remove burrs efficiently and to have a good brushing effect on the burrs on the arc surface and the hook part; during the brushing process, the drive of the first motor 220 and the second motor 330 can be paused first, and observation can be made through the working port 111; after confirming that the burrs on the surface of the lead terminal 999 have been brushed off, the pressing cylinder 420 drives the pressing seat 410 to move away from the mounting part 211, and finally the lead terminal 999 is removed from the lead terminal burr removal machine manually or by using a robot through the working port 111 to complete the removal of the burrs on the lead terminal 999.

[0059] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the existing technology, and all of these modifications fall within the scope of protection of the present invention.
