[0023] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, it will be readily apparent to those skilled in the art that the present invention may be implemented in other ways different from those described herein. Therefore, other possible implementations that can be obtained by those skilled in the art based on the embodiments described herein are all within the scope of protection of this application.

[0024] The words or terms indicating direction, such as "up" and "down," described in the following embodiments are for clarity. In practical applications, the present invention can be placed in any convenient and arbitrarily.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, a chip removal fixture is used to remove a chip from a processing box 60, wherein the chip is disposed on a chip holder 611 of the processing box 60 (other parts of the processing box 60 are omitted in the figure). The chip holder 611 is disposed at one end of the box body of the processing box 60. The chip removal fixture includes: a positioning part 121 connected to the processing box 60; a cutting member 41 having a cutting part 501 and capable of cutting the box body; and a support and guide part supporting and guiding the cutting member 41. The cutting part 501 of the cutting member 41 is disposed toward the chip holder 611, and the cutting member 41 can cut the chip holder 611, cutting at least a portion of the chip holder 611 together with the chip from the box body, thereby separating the chip from the box body. In this embodiment, the chip holder 611 is cut by setting the cutting part 501, and at least a part of the chip holder 611 is cut off from the box together with the chip. This avoids deformation of the chip holder 611 during disassembly, which would squeeze and damage the chip and make it unusable. At the same time, the positioning part 121 is also provided, which can quickly, accurately and reliably connect the processing box, making it more convenient to use.

[0027] The chip disassembly fixture 40 includes a cutting component 41 and a support frame 42. The support frame 42 includes a positioning part 121 and a support guide part. The positioning part 121 is used for positioning and connecting with the processing box 60. The support guide part is used for supporting and guiding the cutting component 41 to cut the chip. The cutting component 41 includes a cutting part 501 and a driving part for driving the cutting part 501 to cut the chip socket 611. The cutting part 501 is used to cut the chip socket 611. The cutting part 501 can be a strip-shaped, sheet-shaped, or ring-shaped cutting head 501. The driving part can be electric, manual, pneumatic, or other driving methods. When the cutting part 501 is strip-shaped or sheet-shaped, it cuts the chip socket 611 by reciprocating motion. When the cutting head 501 is ring-shaped, it cuts the chip socket 611 by rotating the cutting head 501.

[0028] In this embodiment, the support guide portion of the support frame 42 is a light hole 502, which faces the chip holder 611. The light hole 502 can be a continuous hole or a discontinuous hole, as long as it can support and guide the connecting rod 413. The driving method of the driving unit is manual. The driving unit includes a connecting rod 413 and a crank handle 414 connected to the connecting rod 413. The connecting rod 413 is disposed in the light hole 502. The connecting rod 413 and the crank handle 414 can be integrally formed or separately disposed. The crank handle 414 is connected to the connecting rod 413. One end of the connecting rod 413 is connected to the cutting part 501. The connecting rod 413 and the cutting part 501 can be connected in a detachable or non-detachable manner. The cutting part 501 is an arc-shaped or ring-shaped cutting head 501. The cutting part 501 has protruding teeth in the direction facing the chip holder 611. The number of protruding teeth is at least one. The protruding teeth can be saw teeth or cutting teeth. The saw teeth can be saw teeth that tend in one direction. Rotating and cutting in the opposite direction of the saw teeth is smoother and less labor-intensive. The cutting trajectory of the cutting component 41 is parallel or perpendicular to the electrical contact surface of the chip.

[0029] It is understood that the cutting head 501 may not have protruding teeth, and the cutting head 501 may be heated to soften or melt the part of the processing box 60 that is in contact with the cutting head 501 before cutting. The cutting head 501 may also be sharpened and cut off the chip holder 611 by rotating and applying pressure in the direction of the chip holder 611. The cutting head 501 may be driven directly or indirectly by the crank handle 414, such as the connecting rod 413 indirectly driving the cutting head 501 through the reduction gear.

[0030] like Figure 4As shown, the other end of the crank handle 414 connected to the connecting rod 413 is provided with a grip portion 504. Alternatively, the grip portion 504 can be described as being located at the end of the crank handle 414 furthest from the connecting rod 413. The grip portion 504 is rotatably connected to the crank handle 414. When the crank handle 414 is rotated by gripping the grip portion 504, the grip portion 504 and the crank handle 414 rotate relative to each other. Simultaneously, an external force is applied towards the chip holder 611 when the crank handle 414 is rotated, causing the connecting rod 413 to rotate and move towards the chip holder 611. The cutting part 501 then cuts the chip holder 611.

[0031] Furthermore, the cutting component 41 includes a second elastic element 505, which causes the connecting rod 413 to maintain a tendency to move towards the chip. During the cutting process, the connecting rod 413 continues to move towards the chip holder 611, and cutting can be performed without applying an external force towards the chip holder 611 to the crank handle 414. The second elastic element 505 is disposed between the connecting rod 413 and the support frame 42.

[0032] Furthermore, in this embodiment, the optical aperture 502 is a discontinuous aperture, with a bare structure in the middle section. A limiting structure is provided between the connecting rod 413 and the support frame 42 to restrict the sliding of the connecting rod 413 along the chip holder 611 at a specific position. That is, after the connecting rod 413 leaves the specific position, the limiting structure cannot restrict the sliding of the connecting rod. The limiting structure includes a protrusion 506 provided on the connecting rod 413 or the cutting part 501, and a protrusion 507 provided on the support frame 42. The protrusion 507 is provided at the optical aperture. In the exposed section of section 502, there is at least one protrusion 507 and one protrusion 506. The protrusion 507 is positioned close to the connecting rod 413. When the connecting rod 413 is moved away from the chip holder 611 and rotated by a certain angle, the protrusion 507 abuts against the protrusion 506, restricting the movement of the connecting rod 413 towards the chip holder 611. When cutting is required, the connecting rod 413 is rotated by a certain angle, the protrusion 507 disengages from the protrusion 506, and the connecting rod 413 can move towards the chip holder 611 for cutting. This design avoids interference between the cutting section 501 and the processing box 60 during the assembly process of this embodiment.

[0033] Furthermore, the chip disassembly fixture 40 also includes an observation hole through which at least a portion of the chip can be observed, allowing for monitoring of the cutting progress during the cutting process.

[0034] Furthermore, the cutting member 41 includes a chip holder 611 ejecting from the cutting section 501 and a chip ejection section. When the cutting section 501 is an arc-shaped or annular cutting head 501, the cut chip holder 611 and chip may fall into the cutting head 501. The ejection section can be an opening provided near the cutting section 501. A long strip is inserted into the cutting section 501 through the opening to eject the chip holder 611 and chip. Alternatively, the ejection section can be a push rod 508 provided inside the connecting rod 413. Pushing the push rod 508 can cause the push rod 508 to enter the cutting section 501 and eject the cut chip and chip holder 611 from the cutting section 501. Specifically, the connecting rod 413 has a through-hole along its length, which connects to the cutting section 501. A push rod 508 is located within the through-hole, with one end of the push rod 508 protruding from the crank handle 414. When the push rod 508 is pushed from outside the crank handle 414, the other end of the push rod 508 enters the cutting section 501, pushing the chip holder 611 and the chip out of the cutting section 501. A pushing part 509 is located at the end of the push rod 508 protruding from the crank handle 414. The shape of the pushing part 509 is larger than the inner hole of the connecting rod 413, preventing the connecting rod 413 from being over-inserted into the inner hole and making it difficult to remove. The end of the push rod 508 near the chip holder 611... A one-way limiting part 510 is provided. The limiting part 510 is elastically deformable. The limiting part 510 enters the inner hole unidirectionally along the direction towards the chip holder 611 and is locked at the end of the connecting rod 413 near the cutting part 501. Specifically, along the length direction of the optical aperture 502, the outermost shape of the cross section of the limiting part 510 near the chip is smaller than the diameter of the optical aperture 502, and the maximum cross section of the other end of the limiting part 510 is larger than the diameter of the optical aperture 502 and can undergo elastic deformation. Pressing the limiting part 510 can push the push rod 508 out of the inner hole. In this embodiment, the limiting part 510 is in the shape of a "V". There are two limiting parts 510, which are arranged opposite to each other on both sides of the end face of the connecting rod 413. It is understood that the shape of the limiting part 510 is not limited to a "V" shape; other shapes that serve the same limiting function are also acceptable. An elastic element may be provided between the connecting rod 413 and the push rod 508. This elastic element ensures that the push rod 508 maintains a tendency to move towards the crank handle 414. The elastic element may be a spring or an elastic structure. In this embodiment, the inclusion of an elastic element prevents the push rod 508 from accidentally displacing during the cutting process, thus avoiding interference with the cutting process.

[0035] like Figure 4As shown, further, when the cutting part 501 is annular or arc-shaped, the diameter of the cutting part 501 is D, and the vertical distance from the force application point of the crank 414 to the axis of the cutting part is H, where H ≥ 2D. In this embodiment, the force application point of the crank 414 is located at the axis of the grip part 504. Preferably, 6D ≥ H ≥ 2D. Cutting within this range of H requires less effort and is more efficient.

[0036] Furthermore, the positioning part 121 includes a guide part 511, which guides the positioning part 121 to connect with the processing box 60. The guide part 511 is set according to the edge or open position of the processing box 60, so that the positioning part 121 can be engaged in the corresponding position, ensuring that this embodiment can quickly connect with the processing box 60 and that the cutting position is accurate. It can be understood that the positioning part 121 can be connected to the processing box 60 in the horizontal or vertical direction, and the connection method can be a snap-fit ​​or limiting method, as long as it performs the positioning function.

[0037] Furthermore, the positioning part 121 is provided with a locking part 512 that can control the tightness of the connection between the positioning part 121 and the processing box 60, making it easier to assemble and disassemble the processing box 60 and the positioning part 121. The locking part 512 includes a pressing part 513 and a locking part 514. A support part connected to the support frame 42 is provided between the pressing part 513 and the locking part 514. The locking part 514 is used to connect to and lock into the processing box 60. The pressing part 513 is used to control the tightness of the locking part 514, so that the locking part 514 is separated from or locked into the processing box 60. Specifically, the pressing part 513 and the locking part 514 have a certain elastic deformation capability under the support of the support part. When the pressing part 513 is pressed, the locking part 514 is released from the connection with the processing box 60. When the pressing part 513 is released, the pressing part 513 and the locking part 514 return to their original state under the action of elastic force. The engaging structure of the engaging part 514 is a quick-connect structure, which is a wedge engaging structure 515 with the inclined surface facing the processing box 60. Under the action of elastic deformation, the engaging part 514 can be directly inserted into the processing box 60. After reaching the limited position, the engaging part 514 engages with the processing box 60.

[0038] Example 2

[0039] like Figure 5 and 6As shown, the main difference between this embodiment and embodiment 1 is that the optical hole 502 is a threaded hole. The threaded hole can be a continuous hole or a discontinuous hole, and the thread of the threaded hole can be only set in one section, as long as it can play a supporting and guiding role for the connecting rod 413. The outer curved surface of the connecting rod 413 is provided with a thread that matches the threaded hole. When the connecting rod 413 is rotated, the connecting rod 413 can move along the direction of the chip holder 611 and simultaneously apply pressure to the chip holder 611 to cut it.

[0040] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the scope of the invention. Any person skilled in the art may make modifications without departing from the scope of the invention; all variations or modifications made in accordance with the present invention shall be covered by the protection scope of the present invention.
