[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. When describing the embodiments of the present application in detail, for the convenience of explanation, the schematic diagram will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present application. In addition, in actual production, the three-dimensional space dimensions of length, width and depth should be included.
[0024] Some embodiments of the present application provide a wire clamp cleaning tool, referring to Figure 1 ,include:
[0025] A body 100, wherein the body 100 includes a front end portion and a rear end portion that are opposite to each other and are distributed along an extension direction of the body 100;
[0026] A cleaning head 101 is provided at the front end of the body 100, and the cleaning head includes a driving device 103 and a grinding sheet 102 connected to the driving device 103, and the driving device 103 is used to drive the grinding sheet 102 to move in a direction parallel to the extension direction, so as to clean the wire clamp 201 (reference Figure 3-Figure 5 ) to clean the inner wall of the clamp.
[0027] Specifically, the body 100 serves as the main structure of the wire clamp cleaning jig. Both ends of the body 100 extend along an extension direction, and in this embodiment, the extension direction is a direction parallel to the x-axis. The body 100 includes a front end and a rear end relative to each other along the extension direction (or in a direction parallel to the x-axis), and the cleaning head 101 is disposed at the front end of the body 100. In some embodiments, the body 100 is columnar, specifically, a cylindrical or polygonal columnar shape.
[0028] In some embodiments, the body 100 is made of metal or plastic.
[0029] In some embodiments, the wire clamp cleaning fixture further includes: a sealed inner cavity 104 and a liquid infusion pipeline (not shown in the figure), wherein the sealed inner cavity 104 is located in the body 100 and is used to store a cleaning liquid 105, and the liquid infusion pipeline connects the sealed inner cavity 104 and the cleaning head 101, and is used to transport the cleaning liquid 105 in the sealed inner cavity 104 to the frosting sheet 102 of the cleaning head 101, and the wire clamp 201 on the wire bonding device (reference Figure 3-Figure 5 ) when cleaning, since the frosting sheet 102 has the cleaning liquid 105, it is more conducive to removing the residue or stain on the inner wall surface of the clamp mouth, thereby improving the cleaning efficiency.
[0030] In some embodiments, one end of the infusion pipe is opened to communicate with the sealed inner cavity 104 , and the other end of the infusion pipe is opened toward the frosting sheet 102 , so that the cleaning liquid 105 in the sealed inner cavity 104 is transferred to the frosting sheet 102 through the infusion pipe.
[0031] In some embodiments, the cleaning liquid 105 may be alcohol or isopropyl alcohol, or may be other suitable cleaning liquids. In some embodiments, a portion of the body 100 is a transparent area, and the transparent area may be made of a light-transmitting material so that the storage amount of the cleaning liquid 105 in the sealed inner cavity 104 can be viewed, so that when the equipment maintenance personnel or the operator finds that the cleaning liquid 105 in the sealed inner cavity 104 is insufficient through the transparent area, the cleaning liquid can be added in time.
[0032] In some embodiments, a filter is provided on the infusion pipeline between the sealed inner cavity 104 and the cleaning head 101 to prevent residue or contamination on the wire clamp from flowing back into the sealed inner cavity 104 through the frosting sheet 102 and the cleaning fluid in the infusion pipeline during the cleaning process, thereby contaminating the cleaning fluid in the sealed inner cavity 104.
[0033] In some embodiments, the rear end of the body 100 has a detachable cover 112, and the cover 112 closes the opening of the sealed inner cavity 104. When it is necessary to add cleaning liquid to the sealed inner cavity 104, the cover 112 is unscrewed or removed.
[0034] The cleaning head 101 is disposed at the front end of the body 100, and the cleaning head 101 includes a driving device 103 and a frosting sheet 102 connected to the driving device 103. The frosting sheet 102 can move in a direction parallel to the extension direction under the drive of the driving device 103. Therefore, the equipment maintenance personnel hold the wire clamp cleaning jig of the present application, and extend the frosting sheet 102 on the cleaning head 101 into the wire clamp 201 on the wire bonding equipment (refer to Figure 3-Figure 5 ), the driving device 103 drives the frosting sheet 102 to move in a direction parallel to the extending direction, and the frosting sheet 102 is moved in a direction parallel to the extending direction to remove (or clear) the residue or stain on the inner wall surface of the clamping opening of the wire clamp 201, thereby realizing automatic cleaning of the inner wall of the clamping opening of the wire clamp 201 on the wire bonding equipment, and because the movement direction of the frosting sheet is parallel to the surface direction of the inner wall of the clamping opening of the wire clamp 201, the damage to the inner wall of the wire clamp 201 during cleaning is minimal. In addition, when the wire clamp 201 is cleaned by the wire clamp cleaning jig of the present application, there is no need to remove the wire clamp 201 from the wire bonding equipment, which saves cleaning time and eliminates the risk of damage to the wire clamp 201 when it is repeatedly disassembled and assembled.

When the forward switch 109 is pressed, the first drive circuit drives the motor to rotate forward, thereby driving the belt-type rolling component 103b, the belt and the annular frosting sheet 102 to roll clockwise in a direction parallel to the extension direction (x-axis direction), so that the frosting sheet 102 performs forward cleaning on the inner wall of the wire clamp opening on the wire bonding device. When the reverse switch 111 is pressed, the first drive circuit drives the motor to rotate reversely, thereby driving the belt-type rolling component 103b, the belt and the annular frosting sheet 102 to roll counterclockwise in a direction parallel to the extension direction (x-axis direction), so that the frosting sheet 102 performs reverse cleaning on the inner wall of the wire clamp opening on the wire bonding device. When the speed regulator is adjusted, the first drive circuit controls the speed of the motor. In a specific embodiment, the speed regulator can have three gears: low, medium and high, corresponding to the motor speeds of low, medium and high.
