Description

Technical Field

[0001] This utility model relates to the field of tweezers technology, and more specifically, to a special tweezers for electrode fabrication. Background Technology

[0002] During electrode fabrication, the electrode wires are extremely thin. When winding them with ordinary tweezers, the flat and angular nature of the tweezers easily causes irreversible bends, creases, or even breakage, rendering the nearly completed electrode unusable. Furthermore, the electrode wires need to be bent into an approximate S-shape during fabrication, but ordinary tweezers, with their flat and angular structure, are neither convenient nor suitable for bending the wires to the required angle.

[0003] Therefore, there is an urgent need for a special type of tweezers for electrode fabrication to solve the above-mentioned technical problems. Utility Model Content

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Example

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a special tweezers for electrode fabrication, including two clamping arms connected at the tail end. Each clamping arm has a clamping part 1 extending from its front end. The clamping part 1 is provided with a shaping section 2 for winding electrode wire. The part of the shaping section 2 that fits with the electrode wire is provided with an arc surface.

[0027] Understandably, in order to achieve stable and reliable surface contact when using specialized tweezers to hold the electrode wire during operation, thereby reducing the possibility of irreversible bending, creases, and breakage of the electrode wire, this invention incorporates a cylindrical clamping part, either partially or entirely, of the clamping part 1 to ensure stable and reliable surface contact when holding the electrode wire. This design effectively utilizes the shaping section 2 of the clamping part 1 to lightly clamp the electrode wire for S-bending, thus preventing damage to the electrode wire.

[0028] In order to achieve an effective arc surface for the shaping segment 2, in this embodiment the shaping segment 2 can be set as a cylinder.

[0029] It is understood that by setting the shaping segment 2 as a cylinder, this utility model can facilitate manufacturing and reduce production difficulty. The shaping segment 2 shown can be configured as a semi-cylinder, except that the surface in contact with the electrode wire is an arc surface. The aforementioned semi-cylinder is a cylinder with sidewalls that combine an arc surface and a plane, i.e., a cylinder longitudinally sectioned along its centerline.

[0030] Furthermore, to facilitate the S-bending of the electrode wire, in this embodiment, the radius of the shaping section 2 is the same as the radius of the S-bend formed after the electrode wire is manufactured. This arrangement effectively reduces the number of clamping operations, improves clamping efficiency, and reduces the possibility of electrode wire damage.

[0031] Furthermore, considering that the electrode wire is typically placed on a workbench for shaping during operation of this embodiment, the end of the clamping arm near the shaping section 2 is bent to one side, with the angle between the bending direction and the length direction of the clamping arm being greater than or equal to 80° and less than or equal to 100°. By setting the bending angle of the clamping arm as described above, it is possible to ensure a highly linear relationship between the displacement of the clamping point and the hand operation input, greatly improving the accuracy of control. Specifically, the angle between the bending direction and the length direction of the clamping arm can also be set to 90°. The mechanical guidance formed by this angle allows the shaping section 2 to generate a more concentrated radial wrapping force on the electrode wire, effectively suppressing the micro-motion slippage of the electrode wire on the shaping section 2 during bending, thereby ensuring the geometric repeatability of each "S"-shaped bending part and providing a key process guarantee for the mass production of highly consistent microelectrodes.

[0032] At the same time, combined Figure 3 The schematic diagram of the clamping arm end structure shown illustrates that, to facilitate effective clamping of the electrode wire during the shaping process, the inner surface 4 of the clamping part 1 in this embodiment is tangent to the shaping section 2 via an arc. This design effectively reduces the probability of gaps existing between the two shaping sections 2 when the two clamping arms are in a closed state, preventing effective clamping of the electrode wire. Similarly, in some specific embodiments, the shaping section 2 may only constitute a part of the clamping part 1, with a connecting part between the shaping section 2 and the clamping arm. To reduce the possibility of gaps existing between the two shaping sections 2 when the two clamping arms are in a closed state, those skilled in the art can choose to design the connecting part not to protrude from the inner surface, so that when the two clamping arms are in a closed state, the two shaping sections 2 form a line contact for loading.

[0033] See further Figure 3In this embodiment, considering the practical need to clamp the electrode wire from the worktable, the shaping section 2 is preferably located at the end of the clamping part 1 away from the clamping arm. This arrangement effectively increases the probability of clamping the electrode wire in one go. Furthermore, considering that the electrode wire is typically a 0.034mm diameter platinum-iridium alloy wire, in this embodiment, the end face 11 of the shaping section 2 is connected to and perpendicular to the arc surface of the shaping section 2. In other words, the edges of the shaping section 2 are not chamfered. This method eliminates the approximately triangular gap formed at the top of the two shaping sections 2 when the two clamping arms are closed, preventing the electrode wire from being drawn into this gap and affecting the shaping efficiency of the electrode wire.

[0034] Meanwhile, this application considers that the S-bend curvature of the electrode wire shaping may vary depending on the requirements, and therefore different curvatures are adopted. Therefore, the clamping part 1 is detachably connected to the clamping arm to adapt to different shaping needs. Furthermore, in this embodiment, the diameter of the portion of the clamping part 1 exposed to air is set to 0.28-0.31 mm to better match the electrode wire shaping process.

[0035] Furthermore, to expand the usability of the single-diameter clamping part 1, in this embodiment, a silicone sleeve 3 is fitted onto the clamping part 1. By providing the silicone sleeve 3, when the silicone sleeve 3 contacts the surface of the electrode wire, the material undergoes microscopic deformation to conform to the wire's contour, transforming concentrated point contact into a surface contact area with a damping effect. This contact method significantly increases static friction by increasing the effective contact area, effectively suppressing the minute slippage of the electrode wire within the tweezers during bending, ensuring the accuracy of the forming angle; the soft properties of silicone absorb unavoidable minor vibrations and over-impact forces during operation, acting like a mechanical filter to protect the fragile electrode wire from indentation or deformation damage.

[0036] Given the extremely thin electrode wire, typically only 0.034 mm, an electron microscope is usually required to assist in clamping and bending the wire during its shaping. Furthermore, the electrode contacts and the electrode wire are made of the same platinum-iridium alloy, typically silver-white. To facilitate operation in the high-brightness environment under electron microscope illumination and improve the operator's ability to clearly observe the process, a coating is provided on the clamping part 1 in this embodiment. The color of this coating differs from that of the clamping part 1, thus facilitating observation. Simultaneously, to create contrast in the operating environment and guide observation of the electrode wire and the operation process, the coating color is preferably set to a high-saturation color in this embodiment. A high-saturation color refers to a color with a saturation (Croma value, C) greater than 80 in the CIE LCh° color space. It should be noted that in this embodiment… Figure 3 The silicone sleeve 3 and coating are not shown in the image.

[0037] In addition, this utility model also includes a tool system for electrode fabrication, including a housing, a fixed bracket disposed in the housing, special tweezers disposed on the fixed bracket, and multiple clamping parts 1 of various specifications that are matched with the special tweezers.

[0038] The fixing bracket is a flexible bracket, which is equipped with special tweezers and multiple clamping parts 1 of various sizes. It is used to store the special tweezers and the clamping parts 1 and prevent them from falling out.
