Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of semiconductor manufacturing, and particularly relates to a clamp for disassembling a plug-in mounted component. BACKGROUND

[0002] In many devices or apparatuses, plug-in mounted components are widely used, especially in semiconductor devices, and such components often involve embedded mounting. Due to the compact structure of the device, limited operation space, and complex and variable component shapes, the traditional disassembly method usually needs to use multiple special tools to complete the operation, which is tedious and inefficient.

[0003] At present, for a specific type of component, a special clamp is usually designed according to its specific shape characteristics to achieve stable clamping and disassembly. Although such a clamp shows good adaptability and operational convenience in a specific application scenario, its application range is extremely limited, and it can only be compatible with components of a specific shape or size, and lacks universality. Once the component shape changes, or different specifications and structures of elements need to be disassembled, the original clamp often cannot be used, and a new clamp must be designed and manufactured, increasing the cost and development cycle.

[0004] In addition, the clamping force of such a clamp usually depends on the operator's hand feeling control during use, and lacks precise adjustment mechanism, which can easily lead to damage to the component due to excessive clamping force, or unstable clamping due to insufficient clamping force, and has a high operation risk.

[0005] Therefore, there is an urgent need for a universal clamp with simple structure, convenient operation, wide application range and adjustable clamping force, which can meet the disassembly needs of components of various shapes and sizes, improve operation efficiency, reduce dependence on special tools, and improve the reliability and safety of the overall operation. SUMMARY

[0006] Based on the technical problems existing in the prior art, the present application provides a clamp for disassembling a plug-in mounted component.

[0007] According to the technical scheme of the present application, the present application provides a clamp for disassembling a plug-in mounted component, which comprises a main shaft, a plurality of clamps and a telescopic structure, the telescopic structure is in contact with the movable shaft sleeve, the movable shaft sleeve and the fixed shaft sleeve are sequentially sleeved on the outer side of the main shaft along the axis direction, each clamp comprises a first connecting rod, a second connecting rod and a third connecting rod, the first connecting rod is connected to the fixed shaft sleeve through the third connecting rod which is hinged at both ends, the other end of the first connecting rod is provided with a sliding groove plate, the second connecting rod is slidably arranged in the sliding groove plate, the other end of the second connecting rod is hinged to the movable shaft sleeve, and the middle part of the second connecting rod is hinged to the middle part of the third connecting rod.

[0008] Further, the main shaft is externally provided with a fixed limiting sleeve, which is arranged between the movable sleeve and the fixed sleeve.

[0009] Further, the telescopic structure comprises a first spring, a second spring, a first sleeve and a second sleeve, the first sleeve is sleeved on the outside of the main shaft, the second sleeve is sleeved on the outside of the first sleeve, the second spring is arranged between the second sleeve and the first sleeve, and the handle is further arranged in the first sleeve.

[0010] Further, the first sleeve comprises a main shaft sleeve and a handle sleeve, the inner diameter of the main shaft sleeve is smaller than that of the handle sleeve, and the length of the main shaft sleeve is smaller than that of the main shaft.

[0011] Further, the second sleeve is U-shaped, one end of the second sleeve is adjacent to the movable sleeve, and the inner wall of the other end of the second sleeve is adjacent to the outer wall of the handle sleeve.

[0012] Further, the side wall of the handle is uniformly provided with a plurality of bosses along the circumference, each boss is provided with a groove, and the side wall of the handle sleeve is fixedly provided with a plurality of rolling balls.

[0013] Further, the handle is externally sleeved with a handle knob at the end away from the main shaft.

[0014] Further, the handle is provided with a fixing member between the handle and the first sleeve.

[0015] Further, the handle is provided with a limiting block at the end close to the main shaft, and the distance between the limiting block and the handle sleeve is smaller than the height of the rolling balls protruding on the handle sleeve.

[0016] Further, the distance between the boss and the handle sleeve is smaller than the height of the rolling balls protruding on the handle sleeve, and the distance between the recessed part of the groove and the handle sleeve is greater than the height of the rolling balls protruding on the handle sleeve.

[0017] Compared with the prior art, the above technical scheme of the clamp for disassembling the plug-in mounting component has the following beneficial technical effects: The present application realizes that one clamp jaw can adapt to objects of various sizes and different shapes by adopting the articulated multi-link clamp jaw, and the adjustment of the clamping force is realized by driving the sliding sleeve through the telescopic structure, thereby improving the adaptability range of objects with different installation tightness for disassembly.

[0018] This invention fixes the limiting sleeve on the main shaft and positions it between the movable sleeve and the fixed sleeve. The mechanical hard limit directly determines the limit stroke of the movable sleeve, so that the maximum opening of the gripper is determined only by the axial length of the limiting sleeve, thus avoiding over-travel that could cause the connecting rod slider to collide with the end of the groove.

[0019] This invention employs a telescopic structure combining inner and outer double-layer sleeves and double springs. The two sets of springs work independently and are coaxially nested, shortening the axial dimension and providing two levels of stiffness, resulting in a smoother operating force curve.

[0020] This invention divides the first sleeve into two stepped holes with different inner diameters: a main shaft sleeve and a handle sleeve. The main shaft sleeve is fitted with the main shaft to form the first guide section, and the handle sleeve is fitted with the handle to form the second guide section. One part achieves a dual guide function, reducing the need for additional bearings or bushings.

[0021] The present invention uses a U-shaped second sleeve, with its two ends respectively encircling the outer wall of the movable bushing and the handle sleeve, to form a closed force transmission frame. This allows the thrust of the second spring to be evenly transmitted to the end face of the movable bushing through the bottom of the U-shape, avoiding the movable bushing from tilting or jamming due to uneven load.

[0022] This invention prevents the ball from sliding to the right side of the limiting block by setting a limiting block and limiting the distance between the limiting block and the first sleeve. By limiting the distance between the boss and the groove and the first sleeve, the boss cannot pass through the ball, but can only pass through the groove. Through the cooperation of the groove and the ball, and then rotating the handle, locking is achieved. Attached Figure Description

[0025] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0026] like Figures 1-2 As shown, a clamp for disassembling plug-in mounting components includes a main shaft 1, a telescopic structure, a movable bushing 17, a fixed bushing 15, and a plurality of chucks. Each chuck includes a first connecting rod 11, a second connecting rod 13, and a third connecting rod 14. The number of chucks is not less than three. The fixed bushing 15 and the movable bushing 17 are both sleeved on the outside of the main shaft 1. The fixed bushing 15 is fixed in position, and the movable bushing 17 slides along the main shaft 1. The telescopic structure contacts the movable bushing 17, thereby causing the movable bushing 15 to slide. 7. Slides on the main shaft 1. The first connecting rod 11 is provided with a sliding groove plate 12 on the side adjacent to the main shaft 1. One end of the first connecting rod 11 that is on the same plane as the sliding groove plate 12 and away from the sliding groove plate 12 is hinged to one end of the third connecting rod 14. The other end of the third connecting rod 14 is hinged to the fixed bushing 15. One end of the second connecting rod 13 slides in the sliding groove plate 12. The other end of the second connecting rod 13 is hinged to the movable bushing 17. The middle part of the second connecting rod 13 is hinged to the middle part of the third connecting rod 14.

[0027] Specifically, the telescopic structure controls the sliding of the movable bushing 17 on the main shaft 1, thereby driving the second connecting rod 13 to slide within the slide plate 12. This causes a change in the angle between the second connecting rod 13 and the third connecting rod 14, realizing the opening and closing action of the chuck, thus clamping and disassembling plug-in mounting components of different shapes and sizes. By limiting the number of chucks to no less than three, it is ensured that several chucks can apply clamping force evenly from multiple directions, ensuring the stability and reliability of the clamping process and preventing the components from shifting or being damaged during disassembly. The slide plate 12 constrains the movement trajectory of the second connecting rod 13, improving the accuracy and consistency of the chuck. The connecting rods are connected by hinges, giving the chuck a certain degree of flexibility during clamping, which can adapt to minor unevenness or shape differences on the surface of the component, enhancing the versatility and applicability of the fixture. The fixed bushing 15 remains stationary, providing a stable support base for the entire fixture, while the sliding of the movable bushing 17 becomes the core driving mechanism for the fixture's movement. Combined with the pushing force of the telescopic structure, this enables automated or semi-automated operation of the fixture. This fixture features a compact structure and flexible movement, allowing for the disassembly of complex components in space-constrained environments. It is particularly suitable for the maintenance and replacement of embedded components in semiconductor equipment. By adjusting the output force of the telescopic structure, precise control of the clamping force can be achieved, avoiding uncertainties caused by human operation and improving operational safety and efficiency.

[0028] Specifically, the slide plate 12 is a raised plate disposed on the surface adjacent to the first connecting rod 11 and the main shaft 1. The raised plate has a slide groove along the axial direction to form the slide plate. The opening and closing of the gripper is realized through the slide plate 12, the movable bushing 17, and the second connecting rod 13.

[0029] Specifically, the first connecting rod 11 is provided with an anti-slip plate on the plane adjacent to the main shaft 1. The anti-slip plate is fixedly connected to the first connecting rod 11. The outer surface of the anti-slip plate is higher than the adjacent plane of the first connecting rod 11. The contour edge of the anti-slip plate is flush with the contour edge of the first connecting rod 11. The thickness of the anti-slip plate is uniform. By setting the anti-slip plate, the stability of clamping is improved and slippage is prevented.

[0030] Specifically, a limiting sleeve 16 is provided on the outer side of the main shaft 1. The limiting sleeve 16 is disposed between the movable sleeve 17 and the fixed sleeve 15. The limiting sleeve 16 is fixedly connected to the main shaft 1. The limiting sleeve 16 restricts the range of motion of the sliding sleeve 17. When the movable sleeve 17 slides along the main shaft 1, it prevents the movable sleeve 17 from continuing to move towards the fixed sleeve 15. The axial position of the limiting sleeve 16 is determined according to the length of the groove of the slide plate 12, so that at the moment when the end face of the movable sleeve 17 contacts the limiting surface of the limiting sleeve 16, the end of the second connecting rod 13 just slides to the end of the groove of the slide plate 12. The gripper thus reaches the designed maximum opening angle and cannot continue to expand, thereby locking the upper limit of the gripper stroke in a purely mechanical manner. The end faces of the limiting sleeve 16 and the movable sleeve 17 are provided with impact-resistant washers to prevent the limiting sleeve 16 from being damaged.

[0031] Specifically, such as Figure 3 As shown, the telescopic structure includes a first spring 21, a second spring 22, a first sleeve 23, and a second sleeve 24. The first sleeve 23 is sleeved on the outside of the main shaft 1, and the second sleeve 24 is sleeved on the outside of the first sleeve 23. A second spring 22 is provided between the second sleeve 24 and the first sleeve 23. A handle 31 is also provided inside the first sleeve 23. The first spring 21 is provided between the handle 31 and the first sleeve 23 on the outside of the main shaft 1. By pushing the handle 31, the first spring 21 is compressed. The first spring 21 pushes the first sleeve 23 to move, thereby squeezing the second spring 22 between the first sleeve 23 and the second sleeve 24. The second spring 22 then pushes the second bushing 24 to move, thereby pushing the movable bushing 17 to slide on the main shaft 1, driving the connecting rods to move, and realizing the adjustment of the chuck.

[0032] Specifically, the first sleeve 23 includes a spindle sleeve 231 and a handle sleeve 232. The inner diameter of the spindle sleeve 231 is smaller than the inner diameter of the handle sleeve 232, and the length of the spindle sleeve 231 is smaller than the length of the spindle 1. The second sleeve 24 is U-shaped. One end of the second sleeve 24 is adjacent to the movable bushing 17, and the inner wall of the other end of the second sleeve 24 is adjacent to the outer wall of the handle sleeve 232. By setting the spindle sleeve 231 and the handle sleeve 232 with different radial lengths, it is convenient to set the second spring 22. By setting the length of the spindle sleeve 231 to be smaller than the length of the spindle 1, the first spring 21 is set on the outside of the spindle 1, avoiding displacement while being connected to the first sleeve 23. The second sleeve 24 and the first sleeve are slidable and there is no fixed relationship between them.

[0033] Specifically, such as Figures 4-6As shown, the sidewall of the handle 31 is uniformly provided with a plurality of protrusions 32 along the circumference, and each protrusion 32 has a groove 321. A plurality of balls 35 are fixed to the sidewall of the handle sleeve 232. The number of protrusions 32 is the same as the number of grooves 321. A limiting block 311 is provided at one end of the handle 31 near the main shaft 1. The distance between the limiting block 311 and the handle sleeve 232 is less than the height of the protrusions of the balls 35 on the handle sleeve 232. The distance between the protrusions 32 and the handle sleeve 232 is less than the height of the protrusions of the balls 35 on the handle sleeve 232. The distance between the recessed portion of the groove 321 and the handle sleeve 232 is greater than the height of the protrusions of the balls 35 on the handle sleeve 232. By setting a limiting block 311 and limiting the distance between the limiting block 311 and the first sleeve 23, the ball 35 is prevented from sliding to the right side of the limiting block 311. By limiting the distance between the boss 32 and the groove 321 and the first sleeve 23, the boss 32 cannot pass through the ball 35, but can only pass through the groove 321. Through the cooperation of the groove 321 and the ball 35, the handle 31 is rotated to achieve locking.

[0034] Specifically, a handle 34 is fitted on the outer side of the end of the handle 32 away from the main shaft. The handle 34 is frustum-shaped. The handle 34 improves the feel during operation and makes it easier to operate. At the same time, the handle can be made of different materials and made into different shapes to adapt to different application environments, such as anti-static, heat insulation or increased friction. The handle 34 and the handle 31 are connected by a thread for easy replacement.

[0035] Specifically, a fixing member 33 is provided between the handle 31 and the first sleeve 23. The fixing member 33 is a two-stage bushing. The first stage of the fixing member 33 is located between the first sleeve 23 and the second sleeve 24. The first stage of the fixing member 33 is fixedly connected to the first sleeve 23. The outer diameter of the second stage of the fixing member 33 is larger than the outer diameter of the first bushing 23, which facilitates pressing.

[0036] Specifically, the ball bearing 35 is fixedly disposed on the inner wall of the handle bushing 232, and can be fixed by forming a ball bearing groove on the inner wall of the handle bushing 232.
