[0037] In some embodiments, reference Figure 1 The present application embodiment provides a pair of tweezers for picking up a held object, the tweezers comprising:

[0038] A tweezer handle 1, two tweezer arms 5 and two tweezer heads;

[0039] The two tweezer arms 5 are arranged opposite to each other and are respectively connected to one end of the tweezer handle 1, and each tweezer head is connected to one end of a tweezer arm 5 away from the tweezer handle 1, and the two tweezer heads are arranged opposite to each other and spaced apart;

[0040] Each tweezer head includes a holding portion, and the holding portion includes an outwardly convex anti-slip curved surface;

[0041] When the tweezers hold an object, the two anti-slip curved surfaces are inserted into the held object and abut against the held object away from each other.

[0042] In this embodiment, two tweezers arms 5 are connected to the same end of the tweezers handle 1 to form a forked tweezers body, and the two forked ends of the tweezers body are respectively connected to a tweezer head so that the two tweezers heads are relatively spaced apart; and the tweezers arms 5 can be deformed relative to the tweezers handle 1 to drive the two tweezers heads to be relatively close or relatively far away.

[0043] When the two tweezer heads are relatively close, the two holding parts on the two tweezer heads are also relatively close, so that the two anti-slip curved surfaces on the two tweezer heads can be inserted into the through holes in the held object after being relatively close; and when the two tweezer heads are relatively far away, the two anti-slip curved surfaces can abut against the inner wall of the through hole of the held object after being relatively far away, so as to pick up and transfer the held object.

[0044] In one embodiment, see Figure 1 and Figure 4 The two tweezer heads are respectively a first tweezer head 2 and a second tweezer head 3. One end of the first tweezer head 2 is connected to an end of a tweezer arm 5 away from the tweezer handle 1, and the other end of the first tweezer head 2 forms a first holding portion 24. A first anti-slip curved surface 21 is formed on the first holding portion 24 and protrudes away from the second tweezer head 3; one end of the second tweezer head 3 is connected to an end of another tweezer arm 5 away from the tweezer handle 1, and the other end of the second tweezer head 3 forms a second holding portion 34. A second anti-slip curved surface 31 is formed on the second holding portion 34 and protrudes away from the first tweezer head 2 to pick up annular materials (such as Figure 6 ) as an example, the first anti-slip surface 21 and the second anti-slip surface 31 are used to cooperate with the curved inner wall of the through hole on the annular material, that is, the two tweezers arms of the tweezers are spread apart from each other, so that the anti-slip surfaces of the holding parts of the two tweezers heads abut against the inner wall of the through hole of the annular material, thereby realizing the picking up and transfer of the annular material (i.e. the object being held).

[0045] In one embodiment, the tweezers can be used to pick up a plastic object, and the material of the first tweezer head 2 and the second tweezer head 3 can be bakelite material to ensure the stability of picking up and transferring the object while avoiding contact damage to the object when clamping.

[0046] In one embodiment, the held object needs to be assembled into a mounting slot (such as Figure 7 As shown in the figure, the mounting groove is provided with adhesive backing, and when the two tweezer heads are relatively far apart, the two anti-slip curved surfaces can abut against the inner wall of the through hole of the held object after being relatively far apart, so as to pick up and transfer the held object, ensure a close fit between the held object and the mounting groove, and avoid accidental touching of the adhesive backing of the mounting groove, thereby improving the yield and efficiency of assembly of the held object.

[0047] In one embodiment, see Figure 7 , take the held object as a ring-shaped material as an example (such as Figure 6 Specifically, two tweezers heads of the tweezers are inserted into the through hole of the annular material, and then the two tweezers arms are spread apart to drive the anti-slip curved surfaces of the two tweezers heads to abut against the inner wall of the through hole of the annular material, and the annular material is picked up and transferred to the installation groove, so that the annular material is attached to the first surface with adhesive on the installation groove to complete the assembly. The assembly effect is as shown in FIG. Figure 8As shown; or the annular material is fitted with the second side with adhesive on the installation groove to complete the assembly. The assembly effect is as shown Fig. 9 As shown, in this way, the tweezers of this embodiment can not only be used in a variety of assembly scenarios, but also avoid accidental contact with the adhesive on the back of the installation groove, thereby improving the yield and efficiency of assembling the held object.

[0048] The tweezers provided in the embodiment of the present application include a tweezer handle 1, two tweezer arms 5 and two tweezer heads; wherein, the two tweezer arms 5 are arranged opposite to each other and are respectively connected to one end of the tweezer handle 1, each tweezer head is connected to one end of a tweezer arm 5 away from the tweezer handle 1, and the two tweezer heads are arranged opposite to each other and at intervals; each tweezer head includes a holding portion, and the holding portion includes an outwardly convex anti-slip curved surface; when the tweezers hold an object, the two anti-slip curved surfaces are inserted into the held object and abut against the held object away from each other, so as to realize the picking up and transferring of the held object and ensure the stability of picking up and transferring the held object.

[0049] In one embodiment, the forceps have a pinching state and a releasing state;

[0050] When the tweezers are in a pinching state, the holding portion of the first tweezer head 2 and the holding portion of the second tweezer head 3 can be in the through hole on the held object, and the first tweezer head 2 and the second tweezer head 3 are separated from the held object;

[0051] When the tweezers are in a released state, both the first anti-slip curved surface 21 and the second anti-slip curved surface 31 can abut against the inner wall of the through hole on the held object.

[0052] In this embodiment, see Figure 1 and Figure 2 The end of one tweezer arm 5 away from the tweezer handle 1 has a first connecting structure 11, the end of the other tweezer arm 5 away from the tweezer handle 1 has a second connecting structure 12, the first tweezer head 2 is connected to the first connecting structure 11, and the second tweezer head 3 is connected to the second connecting structure 12.

[0053] When the two tweezers arms 5 are pinched, the first connecting structure 11 and the second connecting structure 12 are close to each other, the holding portion on the first tweezers head 2 and the holding portion on the second tweezers head 3 extend into the through hole on the held object, and the tweezers and the held object are in a separated state.

[0054] After releasing the pinching action on the tweezers, the first connection structure 11 and the second connection structure 12 move away from each other, and the first anti-skid curved surface 21 and the second anti-skid curved surface 31 both move toward the inner wall of the through hole on the held object, and the first anti-skid curved surface 21 and the second anti-skid curved surface 31 can abut against the inner wall of the through hole on the held object to achieve the picking up of the held object, which is convenient for moving the tweezers to drive the movement of the held object. After the held object is moved to the installation position by the tweezers, pinching the two tweezer arms 5 can release the first anti-skid curved surface 21 and the second anti-skid curved surface 31 from abutting against the inner wall of the through hole on the held object, so that the held object can be installed at the installation position, ensuring the installation accuracy and stability of the held object.

[0055] In one embodiment, see Figures 2 to 4 The radius of the convex anti-slip curved surface at the end of the holding portion away from the tweezers handle 1 is greater than the radius at the end of the holding portion close to the tweezers handle 1.

[0056] In this embodiment, the radius of the anti-slip surface gradually decreases in the direction from the end of the holding portion away from the tweezers handle 1 to the end of the holding portion close to the tweezers handle 1, so as to form an outer peripheral surface that gradually shrinks from the distal end to the proximal end of the holding portion; and when the tweezers pick up and transfer the held object through the holding portion, the distal end of the holding portion first penetrates into the through hole of the held object, and then the proximal end of the holding portion approaches or penetrates into the through hole of the held object, so that the two anti-slip surfaces can limit the held object through the distal end of the holding portion when abutting against the inner wall of the through hole of the held object, thereby preventing the held object from detaching from the holding portion and ensuring the stability of the tweezers in clamping and transferring the held object.

[0057] In one embodiment, see Figure 4 The object holding portion is a cylinder composed of a plurality of sector-shaped surfaces with the same center and gradually decreasing radius in the direction of extending the tweezers handle 1.

[0058] In this embodiment, a plurality of fan-shaped structures with gradually decreasing radii constitute the holding portion, and the anti-slip curved surface forms a partial conical surface. This can reduce the volume of the holding portion and simplify the size of the tweezers on the basis of ensuring that the radius of the anti-slip curved surface at the end of the holding portion away from the tweezers handle 1 is greater than the radius at the end of the holding portion close to the tweezers handle 1. Furthermore, the opposing surfaces of the two holding portions can both be planes, so that the two holding portions can be easily aligned with each other when they are relatively close.

[0059] In one embodiment, the holding portion is a cylinder consisting of a plurality of circular surfaces having the same center and gradually decreasing radii in the direction in which the forceps handle 1 extends.

[0060] In this embodiment, a plurality of circular surface structures with gradually decreasing radius constitute the holding portion to form a decreasing circular surface in the direction from the distal end to the proximal end of the outer peripheral side of the holding portion, that is, the holding portion forms a cone. When the tweezers clamp the object, it can not only prevent the object from falling off, but also facilitate the processing and forming of the holding portion.

[0061] In one embodiment, the tweezers can pick up multiple stacked held objects. Specifically, taking the assembly of the ring-flash diaphragm and the ring-flash lamp cover as an example, the ring-flash diaphragm and the ring-flash lamp cover need to be stacked together and placed in the installation groove without touching the adhesive on the notch of the installation groove, and the two anti-slip curved surfaces with gradually decreasing radius can abut against the inner walls of the through holes of the multiple stacked held objects (i.e. the stacked ring-flash diaphragms and the ring-flash lamp cover) after being relatively far away, so as to pick up and transfer the multiple stacked held objects together, and then put the multiple stacked held objects into the installation groove together and fix them with the adhesive. It should be noted that the ring-flash diaphragm and the ring-flash lamp cover both have through holes, and the apertures of the two can be equal or unequal. It is understandable that the number of ring flash diaphragms and ring flash lamp covers can be multiple, for example, one or more ring flash diaphragms and one or more ring flash lamp covers are assembled, and for example, multiple ring flash diaphragms or ring flash lamp covers are stacked and assembled. It should also be noted that the sizes of multiple ring flash diaphragms or ring flash lamp cover layers can be consistent or inconsistent. According to actual conditions, multiple held objects (such as ring flash diaphragms or ring flash lamp cover layers) can be stacked in different combinations, so that the tweezers can clamp multiple stacked held objects and complete the effect requirements of assembling multiple held objects with the mounting grooves.

[0062] In one embodiment, the first anti-slip curved surface 21 and the second anti-slip curved surface 31 are both rough surfaces, and the rough surfaces are used to pick up and fix the held object to prevent the held object from slipping off the tweezers; in addition, the tweezers head can be processed by CNC to ensure the processing accuracy of the tweezers head, and the right angles on the tweezers head can be polished with sandpaper to prevent the tweezers head from scratching the held object.

[0063] In one embodiment, the first tweezers head 2 and the second tweezers head 3 are symmetrically connected to the two tweezers arms 5, that is, the first tweezers head 2 and the second tweezers head 3 have the same structure, so as to avoid the deflection of the held object when the two symmetrical anti-slip curved surfaces abut against the inner wall of the through hole of the held object, thereby ensuring the stability of the tweezers in picking up and transferring the held object.

[0064] In one embodiment, see Figure 4 and Figure 5 Each tweezers head also includes a transition portion, a step is formed at the connection between the transition portion and the holding portion, the surfaces of the two steps are on the same horizontal plane, the projection area of ​​the transition portion in the length direction of the tweezers is larger than the projection area of ​​the holding portion, and the end of the transition portion away from the holding portion is connected to the tweezers arm 5.

[0065] In this embodiment, the two tweezers heads are respectively a first tweezers head 2 and a second tweezers head 3. The first tweezers head 2 includes a first transition portion 23, and a first step 231 is formed at one end of the first transition portion 23 close to the first holding portion 24; the second tweezers head 3 includes a second transition portion 33, and a second step 331 is formed at one end of the second transition portion 33 close to the second holding portion 34. The first step 231 and the second step 331 are in the same plane when clamping the object to be held, so as to contact the object to be held; when the angle of the tweezers is adjusted, the installation angle of the held object can be adjusted by the first step 231 and the second step 331 to ensure that the position of the held object is accurately installed.

[0066] In one embodiment, see Figure 4 and Figure 5 The two tweezers heads are respectively a first tweezers head 2 and a second tweezers head 3. The first tweezers head 2 includes a first fixing portion 22, the first fixing portion 22 is used to connect to one tweezers arm 5, and the first transition portion 23 is located between the first fixing portion 22 and the first holding portion 24; the second tweezers head 3 includes a second fixing portion 32, the second fixing portion 32 is used to connect to another tweezers arm 5, and the second transition portion 33 is located between the second fixing portion 32 and the second holding portion 34;

[0067] A first step 231 is formed at one end of the first transition portion 23 close to the first holding portion 24, and a second step 331 is formed at one end of the second transition portion 33 close to the second holding portion 34. The first step 231 and the second step 331 are used to contact the held object to limit the holding portion in the through hole on the held object to avoid misalignment between the holding portion and the through hole on the held object.

[0068] In one embodiment, the tweezers head is detachably connected to the tweezers arm 5 .

[0069] In this embodiment, two tweezers arms 5 are connected to the same end of the tweezers handle 1 to form a tweezers body, and the tweezers body can be a traditional tweezers body. The tweezers head is detachably connected to the tweezers arm 5 of the tweezers body. The structural integrity of the tweezers can be ensured by simply replacing different tweezers heads, thereby reducing the cost of using the tweezers.

[0070] In one embodiment, each tweezers head further includes a fixing portion, one end of which is fixedly connected to the tweezers arm 5 by a locking member 4, and the other end of the fixing portion is connected to the transition portion.

[0071] In this embodiment, see Figure 3In the two tweezers heads formed by the first tweezers head 2 and the second tweezers head 3, the first tweezers head 2 includes a first fixing portion 22 and a first holding portion 24, the first fixing portion 22 is detachably connected to the first connecting structure 11 of a tweezers arm 5 through a locking piece 4, a first anti-slip curved surface 21 is formed on the side of the first holding portion 24 away from the second tweezers head 3, and a first transition portion 23 is integrally formed between the first fixing portion 22 and the first holding portion 24; the second tweezers head 3 includes a second fixing portion 32 and a second holding portion 34, the second fixing portion 32 is detachably connected to the second connecting structure 12 of another tweezers arm 5 through a locking piece 4, a second anti-slip curved surface 31 is formed on the side of the second holding portion 34 away from the first tweezers head 2, and a second transition portion 33 is integrally formed between the second fixing portion 32 and the second holding portion 34, so as to facilitate the first holding portion 24 and the second holding portion 34 to pick up and transfer the held object on the basis of ensuring the reliability of the connection between the tweezers head and the tweezers arm 5.

[0072] In one embodiment, one ends of the two tweezers arms 5 are close to each other and integrally connected to the tweezers handle 1 , and the other ends of the two tweezers arms 5 extend along the length direction of the tweezers to form two rectangular parallelepipeds that are symmetrical and relatively spaced apart from each other.

[0073] In this embodiment, one end of the two tweezers arms 5 are connected to the same end of the tweezers handle 1 after they are brought together to form a forked tweezers body, so that the two tweezers arms 5 can be deformed away from or closer to each other with the tweezers handle 1 as a fulcrum; and the other ends of the two tweezers arms 5 are extended along the length direction of the tweezers and form mutual symmetry, which can ensure the balance of the two tweezers arms 5 when deformed and ensure that the two tweezers arms 5 can still be symmetrical with each other after frequent deformation.

[0074] The other ends of the two tweezer arms 5 form two relatively spaced rectangular parallelepipeds, which can facilitate the connection between the tweezer head and the tweezer arm 5 through the rectangular parallelepiped, thereby improving the convenience of connecting the tweezer head and the tweezer arm.

[0075] In one embodiment, the area of ​​the inner surface of the cuboid is greater than the area of ​​the surface adjacent to the inner surface, wherein the inner surface is a surface opposite to another cuboid.

[0076] In this embodiment, among the two tweezers arms 5, one tweezers arm 5 forms a first cuboid at one end away from the tweezers handle 1, and the other tweezers arm 5 forms a second cuboid at one end away from the tweezers handle 1, and the first inner surface of the first cuboid and the second inner surface of the second cuboid are opposite to each other, and on the first cuboid, the area of ​​the first inner surface is larger than the area of ​​the adjacent surface, and on the second cuboid, the area of ​​the second inner surface is larger than the area of ​​the adjacent surface, so that the connecting surface of the tweezers head is formed by the first inner surface and the second inner surface, which facilitates the assembly between the tweezers head and the tweezers arm 5.

[0077] In one embodiment, see Figure 1 The two tweezer arms 5 are arranged opposite to each other and at intervals, and each tweezer arm 5 includes an inclined surface portion 51 and a straight surface portion 53, and the inclined surface portion 51 and the straight surface portion 53 are sequentially connected in the extending direction of the tweezer head;

[0078] The two inclined portions 51 extend toward the tweezers handle 1 and gradually approach each other until they reach a common end and are integrally connected to the tweezers handle 1 at the common end. The end of the inclined portion 51 close to the tweezers head is first bent from the outside and then inward to form a bent portion 52. The end of the bent portion 52 close to the tweezers head extends in a straight line toward the tweezers head to form a straight portion 53.

[0079] In this embodiment, one ends of the two inclined portions 51 are connected together to form a common end after being close to each other, and the common end is integrally connected to the tweezers handle 1, and the other ends of the two inclined portions 51 are first bent and extended in a direction away from each other, and then bent and extended in a direction close to each other, so that the other ends of the inclined portions 51 form a bent portion 52, and the end of the bent portion 52 away from the tweezers handle 1 is integrally connected to a straight portion 53, and the straight portion 53 extends in a plane, so that the tweezers head can be connected to the tweezers arm 5 through the straight portion 53.
