Description

Technical Field

[0001] This utility model relates to the field of circuit board component desoldering technology, and in particular to a double-chopstick-shaped electric heating tweezers. Background Technology

[0002] In the field of circuit board component desoldering technology, existing electrically heated tweezers generally adopt a single heating head design. This design has significant limitations when dealing with the desoldering of electronic components on circuit boards. Specifically, since a single heating head can only heat one side, operators must first heat and operate on one side of the component before rotating the circuit board or changing the tool position to perform the same operation on the other side.

[0003] This step-by-step approach not only increases the complexity of the desoldering process but also significantly reduces work efficiency. Especially when handling a large number of or delicate electronic components, step-by-step heating and manipulation can lead to uneven heating of components, increasing the risk of damage and even affecting the overall performance of the circuit board. Furthermore, frequent rotation of the circuit board or changing of tool positions increases the operator's workload and reduces work comfort and accuracy. Therefore, there is an urgent need in the market for electrically heated tweezers that can simultaneously heat and manipulate both sides of the circuit board component leads to simplify the desoldering process, improve work efficiency, reduce the risk of component damage, and alleviate the operator's workload. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a double-chopstick-shaped electric heating tweezers.

[0005] This utility model proposes a double-chopstick-shaped electric heating tweezers, comprising a lower shell and an upper shell fixedly connected. The front ends of the lower shell and the upper shell are rotatably connected to symmetrically arranged handles. Each handle has a heating plate installed inside. Several heat-conducting sleeves are fixed inside the heating plate. Tweezers rods are inserted into the heat-conducting sleeves. The heat-conducting sleeves are designed with a concave structure in the middle, and the concave part contacts the surface of the tweezers rod. The electric heating tweezers are designed with a chopstick-shaped structure to simultaneously contact both sides of the pins of circuit board components.

[0006] Furthermore, a viewing window is installed on the top of the upper housing, and keycaps are movably disposed on both sides of the viewing window on the top of the upper housing.

[0007] Furthermore, the tail of the handle is provided with a limiting recess. When the two handles are at their maximum opening, the limiting recess abuts against the front end of the lower housing. A spring is engaged and fixed inside the lower housing. The spring is set in a "Y" shape, and both ends of the spring abut against the inner surface of the handle, so that the handle, heating plate, and tweezers can automatically open and reset as a whole.

[0008] Furthermore, the front end of the handle is connected to a cylindrical carrier that communicates with the inside of the handle. Threaded holes are pre-drilled around the cylindrical carrier, and a set screw is connected inside each threaded hole. After the set screw is screwed in, it abuts against the surface of the tweezers bar to adjust and fix the position of the tweezers bar.

[0009] Furthermore, a circuit board is also fixedly installed inside the lower housing. The circuit board integrates a display screen, function keys, and a charging interface. The display screen corresponds to the viewing window, and the function keys correspond to the keycaps.

[0010] Furthermore, the charging interface includes a Type-C charging interface and a DC charging interface. The tail ends of the lower housing and the upper housing are provided with through holes for accommodating the Type-C charging interface and the DC charging interface, so as to facilitate the insertion of the corresponding charging head into the Type-C charging interface or the DC charging interface.

[0011] Furthermore, the outer side of each handle is connected to a rubber heat insulation pad, and the outer surface of the rubber heat insulation pad is provided with an anti-slip texture.

[0012] The beneficial effects of this utility model are as follows: By using a dual-heating head synchronous heating design, which is essentially a chopstick structure design, both sides of the circuit board component pins can be heated and operated simultaneously. This avoids the inefficiency and uneven heating of components caused by the need for a single heating head to heat in stages, significantly improving desoldering efficiency and reducing the risk of component damage. In addition, it is equipped with both Type-C and DC charging interfaces, which can be connected to a power cord for operation or connected to a portable power bank for convenient mobile operation.

Detailed Implementation

[0015] Reference Figure 1-5 The present invention proposes a double chopstick-shaped electric heating tweezers, including an upper shell 1 and a lower shell 2 connected by bolts. At the front end of the lower shell 1 and the upper shell 2, symmetrically arranged handles 3 are rotatably connected together. These two handles 3 constitute the main operating part of the chopstick-shaped electric heating tweezers. Each handle 3 has a heating plate 4 installed inside. The heating plate 4 is the initial component for heating the pins of circuit board components. Several heat-conducting sleeves 41 are fixed inside the heating plate 4. Tweezers 5 are inserted into the heat-conducting sleeves 41. The heat-conducting sleeves 41 are designed with a concave structure in the middle, and the concave part is in contact with the surface of the tweezers 5. This design ensures that heat can be efficiently transferred from the heating plate 4 to the tweezers 5. Through the above structural design, the electric heating tweezers are designed as chopsticks so that they can contact both sides of the circuit board component pins at the same time to achieve symmetrical heating. To facilitate users' viewing of the content displayed on the display screen 81, a viewing window 21 is installed on the top of the upper housing 2, and keycaps 22 are movably arranged on both sides of the viewing window 21 on the top of the upper housing 2. The keycaps 22 correspond to the function keys 82 on the circuit board 8 below, and users can operate the electric heating tweezers by pressing the keycaps 22. The tail of the handle 3 is provided with a limiting recess 31. When the two handles 3 are at their maximum opening, the limiting recess 31 abuts against the front end of the lower housing 1, which restricts the handles 3 from opening further and ensures the safety of use. The lower housing 1 has a spring piece 6 that is snapped into place inside. The spring piece 6 is set in a "Y" shape, and both ends of the spring piece 6 abut against the inner surface of the handle 3. When the user releases the handle 3, the spring force of the spring piece 6 will cause the handle 3, heating plate 4, and tweezers 5 to automatically open and reset as a whole, which improves the convenience of use. To ensure a stable installation of the tweezers 5, a cylindrical carrier 32 connected to the interior of the handle 3 is attached to the front end of the handle 3. Threaded holes are pre-drilled around the circumference of the cylindrical carrier 32, and each threaded hole contains a set screw 33. Once screwed in, the set screw 33 abuts against the surface of the tweezers 5, thereby adjusting and fixing the position of the tweezers 5 and ensuring its stability during operation. This structure also facilitates the replacement of the tweezers 5. During the desoldering of circuit board components, different components require tweezers 5 with different tweezer head shapes. When replacement is needed, the set screws 33 can be loosened directly, and the tweezers 5 can be pulled out. Similarly, when installing a new tweezers 5, it can be inserted sequentially into the cylindrical carrier 32 and several heat-conducting sleeves 41, and then all set screws 33 can be tightened.

[0016] Meanwhile, a circuit board 8 is also fixedly installed inside the lower housing 1. The circuit board 8 integrates a display screen 81, a function key 82, and a charging interface 83. The display screen 81 corresponds to the viewing window 21, allowing users to observe the working parameters of the electric heating tweezers through the viewing window 21. The function key 82 corresponds to the keycap 22, enabling users to operate and control the electric heating tweezers.

[0017] The charging interface 83 includes a Type-C charging interface 831 and a DC charging interface 832. The tail ends of the lower housing 1 and the upper housing 2 are provided with through holes for accommodating the Type-C charging interface 831 and the DC charging interface 832. Users can select the appropriate charging interface as needed and insert the corresponding charging head into the heated tweezers for charging, which improves the flexibility of charging.

[0018] In addition, rubber heat insulation pads are attached to the outer side of the handle 3. The outer surface of the rubber heat insulation pads is provided with anti-slip texture. This not only improves the comfort of the user when holding the electric heating tweezers, but also increases the friction between the hand and the handle 3, preventing the electric heating tweezers from falling off due to slippage during use, and further improving the safety of use.

[0019] It should be noted that: 1. When using the electric heating tweezers, the user can operate the keycap 22 and the function key 82 to achieve the effect of heating both tweezer rods 5 or heating only one tweezer rod 5, depending on the user's needs when desoldering circuit board components. The above control process is already known technology and will not be described in detail here. 2. By providing electrical energy to the heating plate 4, the heating plate 4 generates heat energy (that is, converting electrical energy into heat energy). In other words, the control of the circuit and the control of the temperature are conventional techniques for those skilled in the art and are existing well-known techniques, which will not be described in detail here.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
