Detailed Description

In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.

Example 1

This embodiment provides a tool of uncapping, can separate the upper cover 22 and the base 21 of the object of uncapping, and the operation degree of difficulty is low, and it is efficient to uncap, and can avoid upper cover 22 broken or inner structure to damage.

Specifically, as shown in fig. 1, the uncovering jig comprises a pair of pliers 1, wherein the pliers 1 comprises a first pliers head 11, a second pliers head 12, a rotating shaft 13, a first pliers handle 14 and a second pliers handle 15, and the first pliers head 11 and the second pliers head 12 can be driven to be relatively opened or tightened by relatively opening or tightening the first pliers handle 14 and the second pliers handle 15, so as to clamp an object. The forceps 1 may be made of a rigid material, such as stainless steel, etc., and have a certain strength and are not easily deformed. In order to facilitate the operation of workers, the size of the clamp handles can be designed to be suitable for being grasped by a single hand of the workers, and the two clamp handles are applied with inward holding force to easily open the cover.

In order to adapt the pliers 1 to the above-mentioned opening operation of the object with the base and the upper cover, the inner side of the first plier head 11 is convexly provided with the elastic projection 112 and the first projection 111, the inner side of the second plier head 12 is convexly provided with the second projection 121, and the second projection 121 is arranged opposite to the elastic projection 112. When the cover opening jig is used, as shown in fig. 2, the object to be opened is positioned between the two binding clip heads, and the elastic protrusion 112 and the second protrusion 121 are respectively positioned on two opposite sides of the base 21 and abut against the side wall of the base 21 so as to clamp and fix the base 21. The first protrusion 111 is disposed opposite to the upper cover 22 with a certain distance. As the first and

second bits

11 and 12 are tightened, the elastic projection 112 is compressed, so that the first projection 111 comes into contact with the side of the upper cover 22. The grip force continues to be applied, the elastic protrusion 112 continues to be compressed, and the first protrusion 111 abuts the upper cover 22. Because the second protrusion 121 and the first protrusion 111 are made of hard materials and do not deform obviously, the second protrusion 121 and the first protrusion 111 apply huge shearing force to the upper cover 22, the upper cover 22 is pushed away from the original position, the upper cover 22 moves relative to the base 21, and the cover opening effect is achieved.

Due to inertia, the worker cannot immediately stop applying the grip at the moment when the upper cover 22 and the base 21 are separated, and if the duration of the grip is not limited, the upper cover 22 may be easily crushed or the internal structure and the bottom cover 21 may be damaged. In order to avoid the above problem, a buffer spring (not shown) is further provided between the root portions of the first and

second handles

14 and 15, i.e., at a position close to the rotation shaft 13, and both ends of the buffer spring are connected to the first and

second handles

14 and 15, respectively. When the holding power is applied, the buffer spring is stressed and compressed, the elastic restoring force of the buffer spring is opposite to the direction of the holding power, the buffer effect can be achieved at the moment that the upper cover 22 is separated from the base 21, and the damage to the parts of the object to be opened is avoided.

In order to facilitate the use of the cap opening jig, in a natural state, that is, when the elastic protrusion 112 is not compressed, the length of the elastic protrusion 112 protruding the inner side of the first binding clip 11 should be greater than the length of the first protrusion 111 protruding the inner side of the first binding clip 11, so as to improve the clamping effect of the elastic protrusion 112 and the second protrusion 121 on the base 21.

Since the size of the object to be uncapped, such as a semiconductor device, may be relatively small, the upper lid 22 is moved a small distance relative to the base 21, i.e., the upper lid 22 is separated from the base 21. In order to prevent the inner side surface of the second jaw 12 from affecting the movement of the upper cover 22, the inner side surface of the second jaw 12 is provided with a groove 122 at a position corresponding to the first protrusion 111, and the groove 122 can accommodate the upper cover 22. After the upper cover 22 is separated from the base 21, the upper cover 22 can be clamped in the groove 122, so that the upper cover 22 is prevented from falling and being not easy to find.

In order to further improve the uncapping efficiency, before the uncapping jig provided by the embodiment is used, the uncapped object can be baked at a high temperature (about 170 ℃) for a short time (about 10 seconds) so as to reduce the viscosity of the glue between the upper cover 22 and the base 21.

As shown in fig. 3, the elastic protrusion 112 in the present embodiment may include a first spring 1121, one end of the first spring 1121 is connected to the inner side of the first caliper head 11, and the other end is used for abutting against the base 21. In order to prevent the first spring 1121 from being displaced during the compression process, the elastic protrusion 112 may further include a guide sleeve 1122, one end of the guide sleeve 1122 is connected to the first tong head 11, and the other end is open, and the guide sleeve 1122 is sleeved outside the first spring 1121. The first spring 1121 is compressed in the guide sleeve 1122, so that the first spring 1121 can be prevented from twisting and deviating, and the abutting effect of the elastic protrusion 112 on the base 21 can be ensured.

In order to ensure that the first spring 1121 always abuts against the base 21 with a sufficient amount of compression so that the first protrusion 111 pushes the upper cover 22, the length of the first spring 1121 should be greater than the length of the guide sleeve 1122, and the difference between the lengths ensures that the first protrusion 111 applies a sufficient shearing force to the upper cover 22.

Further, in order to improve the abutting effect of the first spring 1121 on the base 21, the elastic protrusion 112 may further include a guide cap 1123, the guide cap 1123 is sleeved on an end portion of the first spring 1121, and the guide cap 1123 may slide in the guide sleeve 1122. In use, the first spring 1121 pushes the end of the guide cap 1123 to abut against the base 21, the contact area is large, and the abutting effect can be improved, so that the base 21 is stably clamped between the elastic protrusion 112 and the second protrusion 121.

In other embodiments, the resilient protrusions 112 may be made of resilient material or partially made of resilient material, so long as they are capable of deforming to some extent in response to application of a gripping force to provide sufficient shear force to open the lid. Wherein, the elastic material can be rubber or silica gel and the like.

Because the object of being uncapped has different sizes, and the high difference of base 21 and upper cover 22 for the object of being uncapped that adapts to different sizes, improves this tool's of uncapping commonality, and the distance between first arch 111 and the elastic bulge 112 is adjustable, during the use, can be according to the distance between the first arch 111 of the size adjustment of the object of being uncapped and the elastic bulge 112 to satisfy different user demands.

Specifically, in the embodiment, the first protrusion 111 is detachably connected to the first binding clip 11, and a plurality of first mounting holes are disposed on the inner side of the first binding clip 11, and the plurality of first mounting holes and the elastic protrusion 112 are located on the same straight line. When it is necessary to adjust the distance between the first protrusion 111 and the elastic protrusion 112, the first protrusion 111 may be coupled with the first mounting hole at a corresponding position so as to be adapted to the size of the object to be uncapped. The first protrusion 111 may be fixed to the first mounting hole in a threaded connection or a snap connection manner.

In other embodiments, the elastic protrusion 112 may be detachably connected to the first binding clip 11, and the elastic protrusion 112 is selectively fixed to one of the first mounting holes. The first protrusion 111 and the elastic protrusion 112 may be detachably connected to the first binding clip 11 and may be connected to the first mounting hole, and the distance between the first protrusion 111 and the elastic protrusion 112 may be adjusted by adjusting the positions of the first protrusion 111 and the elastic protrusion 112.

When the elastic protrusion 112 can be selectively fixed to one of the first mounting holes, the base 21 needs to be clamped and fixed between the elastic protrusion 112 and the second protrusion 121, and therefore, the position of the second protrusion 121 needs to be adjusted accordingly. Specifically, the inner side of the second binding clip 12 may be provided with a plurality of second mounting holes, and the second mounting holes and the first mounting holes are arranged in a one-to-one correspondence manner, and after the position of the elastic protrusion 112 is adjusted, the second protrusion 121 and the second mounting hole at the corresponding position are fixed in a matching manner, so as to ensure that the elastic protrusion 112 and the second protrusion 121 are arranged oppositely.

In order to ensure the stability of the contact between the ends of the elastic protrusions 112, the first protrusions 111 and the second protrusions 121 and the object to be uncovered, the ends of the elastic protrusions 112, the first protrusions 111 and the second protrusions 121 may be provided with anti-slip structures, and the anti-slip structures may be anti-slip stripes, so that the friction force is increased by increasing the roughness of the surfaces of the protrusions, and the surfaces of the ends of the protrusions and the object to be uncovered are prevented from slipping.

As shown in fig. 4, in order to further improve the stability of the contact between the protrusion and the object to be uncapped, the end of at least one of the elastic protrusion 112, the first protrusion 111 and the second protrusion 121 may be in an L-shaped structure, and the L-shaped structure includes a first portion and a second portion, where the first portion and the second portion are respectively abutted against two adjacent side surfaces of the object to be uncapped and buckled at the edge of the object to be uncapped, so as to increase the contact area and effectively avoid slipping. Taking the first protrusion 111 as an example, a first portion of the first protrusion 111 abuts against a side edge of the upper cover 22, and a second portion abuts against a top surface of the upper cover 22. The ends of the elastic protrusion 112 and the second protrusion 121 are L-shaped, and can also support the base 21, thereby improving the clamping and fixing effect on the base 21. Meanwhile, the end parts of the first protrusion 111, the elastic protrusion 112 and the second protrusion 121 are matched, so that a frame for fixing an object to be uncapped can be enclosed, and slipping in the uncapping process can be effectively avoided.

Example 2

The present embodiment provides a cap opening jig, which has substantially the same structure as the cap opening jig of embodiment 1, and is different from embodiment 1 in the structure for adjusting the distance between the elastic projection 112 and the first projection 111.

As shown in fig. 5, in the present embodiment, the first protrusion 111 is slidably connected to the first binding clip 11, and a second spring 113 is further disposed between the first binding clip 11 and the first protrusion 111, and the second spring 113 pushes the first protrusion 111 toward the elastic protrusion 112. Specifically, the inner side of the first binding clip 11 is provided with a sliding groove, and the end of the first protrusion 111 extends into the sliding groove and is in sliding fit with the sliding groove. When the tool is used, the compression spring enables the first protrusion 111 to slide towards the direction away from the elastic protrusion 112, after an object to be uncapped is placed between the first tong head 11 and the second tong head 12, the first protrusion 111 is released, and the first protrusion 111 slides downwards under the action of the second spring 113 until the first protrusion 111 abuts against the upper cover 22. Through the mode that first arch 111 and first binding clip 11 sliding connection, can make a uncapping tool have the commonality, the quilt that adapts to different sizes is uncapped the object. At this time, at least the end of the first protrusion 111 is in an L-shaped configuration so as to restrict the second spring 113 from continuously pushing the first protrusion 111 downward.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
