Description

Technical Field

[0001] The utility model specifically relates to a rapid soldering fixture. Background Art

[0002] Surge protectors, also known as lightning arresters, mainly provide safety protection for various electronic equipment, instruments and meters, and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit.

[0003] When assembling a lightning arrester, the varistor needs to be welded, and the consistency and efficiency of welding are key factors in determining production quality and efficiency. In order to perform batch consistency welding, Chinese patent CN219787198U discloses a welding fixing structure for a lightning arrester, which utilizes a specification fixing block to slide relative to a base, and utilizes a supporting column after sliding to press the varistor to complete the fixation of the varistor. The structure is mainly used for welding the pins of the varistor.

[0004] However, the existing lightning arrester chip needs to be provided with an indicator, and the state change of the indicator is used to realize the indication of the fuse. For example, the Chinese patent CN216624167U discloses a double-cavity compact surge protector, which is provided with a chip component (varistor) and an indicator. The indicator needs to be welded and fixed to the chip component after the spring is compressed. Then, when the varistor plays a protective role, the fuse indicator and its matching solder connection are fused, so that the compressed indicator is reset. For the welding and fixing of this type of lightning arrester, it is not only the electrode welding of the varistor, but also the welding with the indicator. Therefore, the welding and fixing structure for lightning arrester disclosed in the Chinese patent CN219787198U cannot be applied to the welding of this product. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a quick soldering fixture.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] As shown in the figure, a quick soldering fixture is used for welding and fixing the varistor and the indicator of the lightning arrester, which includes:

[0029] A base 1, wherein the surface of the base is provided with a plurality of working surfaces, each of which is provided with a plurality of operating stations, and a plurality of independent working surfaces 11 are provided on the base, and a row of operating stations 12 are arranged in an array in the area of ​​each working surface, and the operating stations can be formed by relying on a stopper, or by relying on a recessed groove structure provided on the surface of the working surface, and the groove structure is adapted to the shape of the product to be welded, and the stopper or the recessed step setting is used to achieve the limitation of the product to be welded, so as to avoid the displacement of the product to be welded during the welding process, and also to facilitate the operator to install the product to be welded in place, thereby improving production efficiency;

[0030] The movable plate 2 is fitted with the base and can move relative to the surface of the base. It has an operating area 21 that cooperates with the working surface. It can realize that the movable plate can only move along its surface through corresponding pressing blocks or guide components to avoid separation of the movable plate and the base, resulting in failure of cooperation. At the same time, it is necessary to set an operating area. The area of ​​the operating area is larger than the area of ​​the working surface, so as to ensure that the movable plate will not affect the welding operation of the operating station. Preferably, the movable plate is set as a frame structure. If two working surfaces are set on the base, the center of the frame structure is adapted to the second working surface, and its front end is adapted to the first working surface. If there are multiple working surfaces, the corresponding number of frame areas minus one can be increased accordingly to ensure that each crossbeam of the movable plate in the vertical moving direction can correspond to a working surface, that is, the front hollow part of each crossbeam is set as an operating area, which cooperates with the working surface to expose the operating station, thereby reducing costs.

[0031] A plurality of pressing members 3 are arranged in the operating area and are arranged corresponding to the indicating members of the products to be welded. When the movable plate moves relatively, the indicating members are driven to move, and the soldering part of the indicating members is aligned with the soldering part of the varistor. The pressing members move with the movement of the movable plate, so they are fixed on the crossbeam to be aligned with the products to be welded placed in the operating station, and the installation and fixing method thereof is simple.

[0032] The driving member 4 is arranged on one side of the moving plate and is used to drive the moving plate to move relative to the base. The driving member can be a manual structure or an automatic structure.

[0033] If it is a manual structure, a push-pull linkage component is adopted, and a connecting rod structure is adopted, which includes a top rod 41, a connecting rod 42 and a handle 43 which are arranged in linkage with the moving plate. The three are hingedly arranged, and the top rod is limited by a guide hole to realize the translation of the moving plate. The push-pull linkage component is not limited to the push-pull method, or it can adopt a screw method, and realize the relative lateral movement of the screw through a hand wheel to drive the moving plate to slide relative to each other. The manual structure is not limited to the above methods, as long as it can realize the position sliding of the moving plate relative to the base.

[0034] If it is an automatic structure, a motor or a cylinder can be used to drive the moving plate to move relative to the base using the power generated by the motor or the cylinder.

[0035] Furthermore, in order to adjust the position of the movable plate, the position of the movable plate can be adjusted by adjusting the length of the driving rod that is fixedly connected to the driving member and the movable plate. The position of the movable plate can be adjusted by replacing the driving rod or by setting an adjusting screw and changing the position of the adjusting screw.

[0036] Furthermore, an installation step 22 is provided on one side of the operating area of ​​the movable plate corresponding to the operating station, and the clamping piece is fixed on the installation step. The installation step is integrally formed on the movable plate and slightly lowered by a certain distance to limit the position of the clamping piece. At the same time, it is also convenient to fix the position of the clamping piece to ensure that its position is fixed in place to avoid damage to the welding product due to displacement of the installation position.

[0037] The soldering requirements of different products can be met by replacing the clamping parts.

[0038] Furthermore, the clamping piece is adjustable in position on the mounting step. Through the adjustable design, the soldering clamp can be adapted to different products. When clamping and fixing different products, the position of the clamping piece can be adjusted in advance to align it with the indicator piece, thereby making the soldering clamp more applicable and having a higher utilization rate.

[0039] Furthermore, the clamping member includes a fixing seat 31 and a clamping arm 32 extending from the fixing seat to the operating station. The clamping arm is coaxially arranged with the indicating member. The weight of the product is reduced by extending the clamping arm, thereby reducing the cost.

[0040] At the same time, a support rod can also be set at the front end of the fixing seat, and the support rod can be used to press the varistor to meet some scenarios where the varistor needs to be fixed, making it more applicable to a wider range of scenarios.

[0041] Furthermore, a matching groove 34 matching with the indicator is provided at the front end of the pressure arm. Since the indicator has certain sharp corners, in order to avoid damaging it, the front end of the pressure arm is set to a matching groove matched with the indicator. The matching groove is matched with the sharp corner to protect the indicator and avoid damage to the indicator when it is compressed. The matching groove can be triangular, arc-shaped or other irregular shapes. The entire clamping part can be replaced according to needs, or the pressure arm can be set to be movably connected, so that the adaptation to different indicators can be achieved directly by replacing the pressure arm.

[0042] Furthermore, the fixing seat is symmetrically provided with strip holes 33 for fixing to the movable plate. The symmetrical arrangement enables the fixing seat to be subjected to more uniform force, thereby ensuring that its position is not easily displaced. In addition, the arrangement of the strip holes can adjust the position of the fixing seat on the movable plate by adjusting the position of the fixing screws.

[0043] Furthermore, a stopper is provided at one end of the operating station away from the clamping piece, and the stopper is provided to limit the side of the product to be welded away from the clamping piece. Under the action of the pressure given by the movable plate, the product to be welded is given resistance toward the clamping piece, ensuring that force is applied on both sides, thereby playing a role of fixing and limiting it, further ensuring that the position of the product to be welded is not easy to change, and ensuring the consistency of soldering.

[0044] Furthermore, a guide assembly is provided between the movable plate and the base, and the guide assembly includes a slider 13 arranged on the base and a slide groove 23 arranged on the back of the movable plate. The two cooperate to achieve a guiding function. In order to ensure the positions of the two, the slider and the slide groove can be set to a dovetail or a structure with a limiter, thereby ensuring that the two always slide during the bonding process.

[0045] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
