Description

Technical Field

[0001] The utility model relates to the technical field of electronic product production and assembly, and particularly relates to a double-bent elbow tweezer device. Background Art

[0002] When assembling ZIF electronic sockets and FPC parts in electronic products, it is difficult to grasp FPC parts with fingers when the FPC parts are small in size, and tweezer tools are needed for assistance. For the assembly of ZIF electronic sockets and FPC parts, the best assembly angle is that the direction of the FPC part is parallel to the socket of the ZIF electronic socket.

[0003] Currently, assembly is generally carried out using tweezers. However, existing straight or bent-tip tweezers have an inherent drawback: when clamping an FPC part, the direction of the FPC part is always the same as that of the tweezers. During the assembly process, due to the height difference between the hand-held position and the tweezer tip, it is inevitable that a large angle is formed between the tweezer and the socket of the ZIF electronic socket, failing to reach the ideal angle of parallel assembly between the FPC part and the socket of the ZIF electronic socket, unable to achieve parallel insertion in one step. Instead, after inserting a little, it is necessary to re-grasp to adjust the angle, which will reduce the assembly efficiency and may cause problems such as incomplete one-time assembly or even damage.

[0042] Embodiment

[0043] This embodiment provides a double-bent elbow tweezer device, as Figures 1 to 5 shown, which includes two tweezer legs fixed together, namely the first tweezer leg 1 and the second tweezer leg 2. The tails of the first tweezer leg 1 and the second tweezer leg 2 are fixed together, and a gap is ensured between the heads of the first tweezer leg 1 and the second tweezer leg 2. Specifically, the first tweezer leg 1 includes a first clamping arm 11 and a first clamping head 12. The first clamping head 12 and the first clamping arm 11 are integrally formed, and there is an arc-shaped smooth transition between the first clamping arm 11 and the first clamping head 12. The first clamping head 12 is arranged at one end of the first clamping arm 11 away from the tail. The second tweezer leg 2 includes a second clamping arm 21 and a second clamping head 22. The second clamping arm 21 and the second clamping head 22 are integrally formed, and there is an arc-shaped smooth transition between the second clamping arm 21 and the second clamping head 22. The second clamping head 22 is arranged at one end of the second clamping arm 21 away from the tail. The part to be installed is an FPC part, and the electronic socket is a ZIF electronic socket.

[0044] The first clamping head 12 is arranged at an angle with the first clamping arm 11. Specifically, the first clamping head 12 is bent towards the direction close to the second clamping head 22. The surface of the first clamping head 12 close to the second clamping head 22 is the first clamping surface, and the plane where the first clamping surface is located is arranged at an angle with the plane where the inner side surface of the first clamping arm 11 is located; the second clamping head 22 is arranged at an angle with the second clamping arm 21. Specifically, the second clamping head 22 is bent towards the direction away from the first clamping head 12. The surface of the second clamping head 22 close to the first clamping head 12 is the second clamping surface, and the plane where the second clamping surface is located is arranged at an angle with the plane where the inner side surface of the second clamping arm 21 is located. A clamping space for clamping the part to be installed is formed between the first clamping surface and the second clamping surface.

[0045] When the part to be installed needs to be installed into the electronic socket, the hands of the staff are respectively placed on the outer sides of the first clamping arm 11 and the second clamping arm 21, move the tweezers to the position of the part to be installed, and press the first clamping arm 11 and the second clamping arm 21, so as to drive the first clamping head 12 and the second clamping head 22 to approach each other until the part to be installed is clamped between the first clamping surface and the second clamping surface. Since the plane where the first clamping surface is located is arranged at an angle with the plane where the inner side surface of the first clamping arm 11 is located, and the plane where the second clamping surface is located is arranged at an angle with the plane where the inner side surface of the second clamping arm 21 is located. As Figure 5 shown, when the electronic socket is placed horizontally, its corresponding socket is also horizontal. When the first clamping head 12 and the second clamping head 22 clamp the part to be installed in a horizontal state facing the socket, the first clamping arm 11 and the second clamping arm 21 are inclined upward, and there is a space for accommodating the hand below the first clamping arm 11 and the second clamping arm 21 at this time. Even if there is a height difference between the hand-held position and the tweezer head, it can ensure that the part to be installed and the plug of the electronic socket are relatively horizontally aligned, enabling parallel assembly, realizing parallel insertion, and reaching the end in one step, without the need to re-grasp and adjust the angle, improving the assembly efficiency. It solves the problem that the hand-held angle does not match the optimal angle required for product assembly. There is no line-of-sight obstruction during assembly, rapid alignment, and it can be assembled in place with a single flat push, reducing the hidden danger of damage caused by forced insertion due to angle mismatch.

[0046] Specifically, as Figures 1 to 5As shown in the figure, one end of the first clamping head 12 away from the first clamping arm 11 extends towards the side with a first extension portion 121, and one end of the second clamping head 22 away from the second clamping arm 21 extends towards the side with a second extension portion 221. The extension directions of the first extension portion 121 and the second extension portion 221 are the same. The inner side surface of the first extension portion 121 is part of the first clamping surface, and the inner side surface of the second extension portion 221 is part of the second clamping surface. Thus, the first clamping head 12 and the second clamping head 22 form an L-shaped elbow. When clamping the part to be installed using the inner side surfaces of the first extension portion 121 and the second extension portion 221, the first extension portion 121 or the second extension portion 221 can be first inserted under the part to be installed, and then the first extension portion 121 and the second extension portion 221 are pressed closer to clamp the part to be installed. With the slender shape of the elbow, it is convenient for the staff to pick up, improving the installation efficiency.

[0047] Moreover, a flexible pad is installed on the surfaces of the first clamping surface and the second clamping surface. The clamping head is provided with a soft rubber pad, which ensures sufficient pressing during clamping. When inserting and assembling, the friction generated by the compressed soft rubber pad has the effect of preventing the part to be installed from sliding and shifting.

[0048] In this embodiment, as Figures 1 to 5 shown, a positioning member 13 is provided on the side of the first clamping surface away from the first extension portion 121. The positioning member 13 is a protrusion. The positioning member 13 is provided on the side of the first clamping surface away from the first extension portion 121. The outer side surface of the positioning member 13 away from the first clamping portion is the first positioning surface 131, and the side surface of the positioning member 13 close to the first extension portion 121 is the second positioning surface 132. The second clamping head 22 is provided with a notch 23 corresponding to the positioning member 13. An inner side of one end of the first clamping arm 11 close to the first clamping head 12 is provided with a positioning groove 14.

[0049] When the tweezers pick up the part to be installed, the positioning member 13 can position the picking position of the part to be installed. The first positioning surface 131 abuts against the upper side edge of the lug of the part to be installed. The second positioning surface 132 abuts against the side edge of the body of the part to be installed, and the other end of the side edge in contact with the second positioning surface 132 overlaps on the inner wall of the positioning groove 14. The plane of the side wall of the positioning groove 14 coincides with the plane of the second positioning surface 132. Ensure that the side surface of the part to be installed can completely fit the second positioning surface 132 and the side surface of the positioning groove 14, with a larger contact area, ensuring the stability of its clamping. At the same time, by manually changing the holding angles of the first clamping arm 11 and the second clamping arm 21, the bottom surface of the part to be installed overlaps in the positioning groove 14. Using side positioning and insertion direction positioning design, two points form a straight line for side positioning, ensuring the levelness and stability of the part to be installed during the installation process.

[0050] The positioning member 13 is arranged on the side of the first clamping surface away from the first extension portion 121, away from the end position of the first clamping head 12, which can effectively prevent it from blocking the parts to be installed from entering the clamping space, maximize the effective clamping area of the first clamping surface, and improve the clamping stability. By providing the notch 23, the notch 23 is arranged corresponding to the positioning member 13. When the first clamping head 12 and the second clamping head 22 approach each other for clamping, the positioning member 13 is inserted into the notch 23, and the inner sides of the first clamping head 12 and the second clamping head 22 can be completely attached, ensuring the clamping effect.

[0051] As Figures 1 to 5 shown, a self-locking buckle 3 is further provided on the first clamping arm 11 of the double-crank elbow tweezer device, including a fixing portion 31, a guiding portion 32 and an abutting portion 33. The fixing portion 31 is plate-shaped, with a mounting hole provided on the upper part, and is fixed on the inner wall of the first clamping arm 11 by screws. As Figure 3 shown, the lower end of the elastic piece is fixed on the fixing portion 31, the upper end of the elastic piece extends upward, the guiding portion 32 is fixed on the upper end of the elastic piece, and is placed on the side close to the clamping arm. The guiding portion 32 is arranged obliquely downward, and the side of the guiding portion 32 away from the elastic piece is the guiding surface. The abutting portion 33 is fixed at the lower end of the guiding portion 32. When the first clamping arm 11 and the second clamping arm 21 approach each other to clamp the parts to be installed, the second clamping arm 21 will first touch the top of the guiding portion 32. Under the action of an external force, the elastic piece will tilt outward, and the side surface of the second clamping arm 21 will move along the guiding surface towards the direction close to the first clamping arm 11 until it moves below the abutting portion 33. Then the elastic piece resets, and the self-locking buckle 3 automatically locks and is in a clamped state, fixing the second clamping arm 21, keeping the tweezers clamped, releasing the downward pressure of the index finger, and at the same time reducing the gripping force of the thumb and middle finger. It reduces the operation fatigue, improves the stability and durability of the operation, and enhances the assembly efficiency.

[0052] In this embodiment, the double-crank elbow tweezer device can replace the design scenario of hand-held FPC assembly, saving more design space for the product.

[0053] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
