Description

Technical Field

[0001] This utility model relates to the technical field of deburring devices, and in particular to a deburring device for spring clips used in anti-theft devices. Background Technology

[0002] An anti-theft device is a device used to prevent intrusion and protect property. It monitors and alarms through specific working principles to notify users or relevant personnel in case of abnormalities. Anti-theft devices are widely used in clothing and supermarkets, primarily to prevent theft and reduce property loss. Anti-theft devices include spring clips. During the manufacturing process, after the spring clips are blanked through stamping, sharp burrs remain on the edges. These burrs affect subsequent production processes and the finished product. They can not only injure assembly personnel but also cause jamming between components during operation, affecting the normal operation of the anti-theft device and increasing the risk of property loss. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that the edges of existing blanks have sharp burrs, which affect the subsequent production process and finished products. Burrs can not only injure assembly personnel, but also cause jamming and other problems during component operation, affecting the normal operation of the anti-theft device. A deburring device for spring sheet of anti-theft device is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a deburring device for spring sheets in anti-theft devices, including a bracket, a rotating barrel, a polishing shaft, and a first motor. The first motor is slidably mounted on the bracket, and the rotating barrel is fixed on the output end of the first motor. A control mechanism is provided on the bracket, and the polishing shaft is rotatably mounted on the control mechanism. The control mechanism is used to control the polishing shaft to enter and abut against the rotating barrel or to disengage from the rotating barrel. The polishing shaft has a connecting section, a polishing section, and an abutting section arranged sequentially. The connecting section is rotatably mounted on the control mechanism. The polishing section is eccentrically arranged with the connecting section and the abutting section. The abutting section is used to abut against the rotating barrel, and the central axis of the abutting section coincides with the central axis of the rotating barrel. Compared with the prior art, this solution uses the first motor to drive the rotating barrel to rotate, and the control mechanism controls the polishing shaft to abut against the rotating barrel. The rotating barrel drives the polishing brick to rotate as well. By improving the polishing efficiency between the internal spring sheet and abrasive through the interaction between the rotating barrel and the polishing shaft, the spring sheet is polished to remove burrs, which is beneficial for subsequent painting processes and improves paint adhesion. Assembly will not cause injury to personnel.

[0005] To improve polishing efficiency, in some preferred embodiments, the polishing section is provided with a plurality of protrusions. By providing protrusions on the polishing section, the protrusions collide with the abrasive and the spring, increasing the contact rate between them and thus improving polishing efficiency.

[0006] In order to enable the protrusions to make better contact with the abrasive and the spring, in some preferred embodiments, the protrusions are arranged along the axial direction of the polishing section and staggered from each other.

[0007] To ensure stable and reliable rotation of the polishing shaft, in some preferred embodiments, a first friction plate is provided on the abutment section, and a second friction plate is provided inside the rotating barrel. The first and second friction plates are arranged opposite to each other and in contact. Through the contact between the first friction plate on the polishing shaft and the second friction plate inside the rotating barrel, the rotation of the rotating barrel drives the polishing shaft to rotate, ensuring stable and reliable rotation of the polishing shaft.

[0008] To implement the control mechanism, in some preferred embodiments, the control mechanism includes a cylinder and a mounting plate. The cylinder is fixedly mounted on a bracket, and the mounting plate is fixedly mounted on the extended end of the cylinder. The polishing shaft is rotatably mounted on the mounting plate. By having the cylinder drive the mounting plate to rise or fall, the polishing shaft is driven to extend into and contact the rotating drum, or to disengage from the rotating drum.

[0009] To prevent abrasive and shrapnel from flying out, in some preferred embodiments, a protective cover is fixedly mounted on the mounting plate, which is used to cover the rotating barrel during polishing.

[0010] To facilitate the addition of abrasives or springs, in some preferred embodiments, the protective cover is provided with an input port, which is provided corresponding to the opening end of the rotating barrel.

[0011] In some preferred embodiments, the bracket is provided with a drive mechanism for driving the first motor to slide.

[0012] To implement the drive mechanism, in some preferred embodiments, the drive mechanism includes a second motor, which is fixedly mounted on a bracket. A screw is rotatably mounted on the bracket along the sliding direction of the first motor. The output end of the second motor is connected to the screw via a transmission connection. A slider is provided on the first motor, and a linear guide rail is provided on the bracket along the sliding direction of the first motor. The slider is slidably mounted on the linear guide rail, and the screw is threadedly connected to the first motor. The second motor drives the screw to rotate, and the screw drives the first motor to slide back and forth on the bracket, which can shake the abrasive and spring pieces inside the rotating drum and facilitate material transfer after completion.

[0013] For better polishing, in some preferred embodiments, the sidewall of the rotating barrel is provided with a through hole, which extends from the outer circumferential surface of the sidewall to the inner circumferential surface. By providing a through hole in the sidewall of the rotating barrel, the removed burrs and scrap can be discharged, and the polishing efficiency can be improved.

[0014] The beneficial effects of this utility model are as follows: When using the deburring device for anti-theft devices, the first motor drives the rotating barrel to rotate, and the control mechanism controls the polishing shaft to abut against the rotating barrel. The rotating barrel drives the polishing brick to rotate as well. The polishing efficiency between the internal spring and the abrasive is improved through the interaction between the rotating barrel and the polishing shaft, thereby polishing the spring and removing burrs. This prepares the material for subsequent painting processes and improves paint adhesion. The device will not cause injury to personnel during assembly, ensuring the stable and reliable operation of the anti-theft device. It avoids the problem of sharp burrs on the edges of existing materials, which affect subsequent production processes and finished products. Burrs can not only injure assembly personnel but also cause jamming and other problems during component operation, affecting the normal operation of the anti-theft device.
