Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture for the resonant components of a photovoltaic filter. Background Technology

[0002] Photovoltaic filters are crucial components in photovoltaic (solar) power generation systems, primarily used to improve power quality. The resonant component is a key part of the photovoltaic filter, mainly used to enhance filtering effectiveness, particularly by effectively suppressing noise and harmonics at specific frequencies. The resonant component typically includes inductors (coils), capacitors, and other components that work together to form one or more resonant circuits. The resonant component of a photovoltaic filter is secured by soldering various electronic components (such as inductors and capacitors) and circuit boards or other metal parts, ensuring smooth current flow and establishing effective electrical connections.

[0003] In existing photovoltaic filter resonant components, during welding, welding fixtures are used to position the resonant components to the PCB board or metal parts. The welding fixtures first need to securely position the circuit board or metal parts, and then position the resonant components based on the positioning of the circuit board or metal parts. Traditional welding fixtures use clamping for positioning, but the resonant components need to be positioned using clamps, which causes the welding part of the resonant components to be obstructed by the clamps, resulting in limitations in the operation of the welding tools. Utility Model Content

[0004] The purpose of this utility model is to provide a welding fixture for the resonant components of a photovoltaic filter, so as to solve the problem mentioned in the background art that the resonant components on the market currently require the use of clamps for positioning, which causes the welding part of the resonant components to be obstructed by the clamps, resulting in limitations in the operation of the welding tools.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for a resonant component of a photovoltaic filter, comprising a welding fixture body and a circuit board. A positioning base plate is provided below the welding fixture body, and symmetrical positioning adjustment plates are provided on the upper end of the positioning base plate. The positioning adjustment plates are bent plate structures, with recessed and protruding portions formed by bending. A lifting drive mechanism is fixed to the middle portion of the recessed portion of the positioning adjustment plate, and transmission screws are symmetrically installed above the recessed portion of the positioning adjustment plate. Side clamps are sleeved and fixed on the transmission screws, and clamping pads are engaged on opposite sides of the side clamps. The bottom of the side clamps contacts and cooperates with the bottom surface of the recessed portion. A connecting plate is connected to the movable end of the lifting drive mechanism, and a resonant component positioning plate is connected between the connecting plates. The resonant component positioning plate contacts and cooperates with the circuit board, and through holes for welding and positioning the resonant component are provided on the resonant component positioning plate.

[0006] Preferably, the positioning adjustment plate is provided with weight reduction holes, and the end of the positioning adjustment plate that is close to each other is respectively clamped to the positioning stabilizing plate with the inherent L-shaped structure, and the positioning stabilizing plate and the recessed part are respectively fixed to the positioning base plate with bolts.

[0007] Preferably, the middle of the positioning and stabilizing plates is connected to a limiting rod, and the two ends of the limiting rod are respectively straight-lined with connecting rods, and the connecting rods are connected to the transmission screw through a coupling.

[0008] Preferably, the protrusion is provided with grooves by stamping, and anti-slip pads are bonded and fixed to the grooves of the protrusion, and the anti-slip pads are in contact with the circuit board.

[0009] Preferably, the clamping pad and the anti-slip pad are positioned correspondingly, and the lower end surface of the clamping pad is lower than the upper end surface of the protrusion.

[0010] Preferably, the connecting plate is a bent plate, and the connecting plate has corresponding circular holes and oblong holes.

[0011] Compared with existing technologies, the advantages of this invention are as follows: The photovoltaic filter resonant component welding fixture has a liftable resonant component positioning plate in the upper area for circuit board positioning. By opening through holes on the resonant component positioning plate for resonant component positioning, the resonant component can be accurately positioned on the circuit board, reducing the need for clamping and stabilizing the resonant component and making the welding operation more convenient. The photovoltaic filter resonant component welding fixture supports and stabilizes the circuit board through a positioning adjustment plate and side clamps. While positioning the resonant component, the resonant component positioning plate can also press down on the circuit board for stabilization, further ensuring the accuracy of the welding positioning between the circuit board and the resonant component.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a welding fixture for a resonant component of a photovoltaic filter, including a welding fixture body 1 and a circuit board 9. A positioning base plate 2 is provided below the welding fixture body 1, and positioning adjustment plates 3 are symmetrically provided on the upper end of the positioning base plate 2. The positioning adjustment plates 3 are bent plate structures, and recesses 303 and protrusions 304 are provided on the positioning adjustment plates 3 through bending. Weight reduction holes 302 are respectively opened on the positioning adjustment plates 3, and the adjacent ends of the positioning adjustment plates 3 are respectively clamped to positioning stabilizing plates 6 with inherent L-shaped structures. The positioning stabilizing plates 6 and the recesses 303 are respectively bolted to the positioning base plate 2. This structure can stabilize the welding fixture body 1 through the cooperation of the positioning adjustment plates 3 and the positioning stabilizing plates 6. The spacing of the positioning adjustment plates 3 can be adjusted to accommodate circuit boards 9 of different sizes. A lifting drive mechanism 10 is fixed to the middle of the recess 303 on each of the positioning adjustment plates 3. A transmission screw 4 is symmetrically installed above the recess 303 on each of the positioning adjustment plates 3. A limit rod 8 moves through the middle of the positioning and stabilizing plates 6, and connecting rods 801 are linearly inserted into both ends of the limit rod 8. The connecting rods 801 are connected to the transmission screw 4 via a coupling. This structure allows the limit rod 8 to be positioned through a bearing structure within the positioning and stabilizing plates 6, enabling the limit rod 8 to rotate smoothly relative to the positioning and stabilizing plates 6. Simultaneously, the limit rod 8 provides relative stability to the positioning and stabilizing plates 6, ensuring accurate positioning of the positioning adjustment plates 3. 801 can only move linearly relative to the limiting rod 8, allowing the connecting rod 801 to move relative to the limiting rod 8 when adjusting the spacing of the positioning adjustment plate 3. The transmission screw 4 is fixed to the connecting rod 801 via a coupling, so that one side of the transmission screw 4, after being driven by a servo motor, can drive the connecting rod 801, the limiting rod 8, and the other side of the transmission screw 4 to rotate synchronously. The spiral structures of the two transmission screws 4 are opposite, which can realize the displacement adjustment of the two side clamping plates 5, thereby allowing the side clamping plates 5 to clamp and release the circuit board 9, ensuring reliable clamping and positioning of the circuit board 9 during the welding of the resonant components. The side clamping plates 5 are fixedly sleeved on the transmission screw 4, and the opposite side of the side clamping plates 5 is engaged with the clamping plate pad 501, and the bottom of the side clamping plates 5 is flush with the concave side. The bottom surface of the recess 303 contacts and engages with the protrusion 304, which has grooves formed by stamping. Anti-slip pads 301 are adhered and fixed to the grooves of the protrusion 304 and engage with the circuit board 9. This structure provides bottom support for the circuit board 9 through the protrusion 304 and anti-slip stability through the anti-slip pads 301, while also protecting the bottom of the circuit board 9. The protrusion 304, through bending, provides reliable support and stability. The movable end of the lifting drive mechanism 10 is connected to a connecting plate 7, and a resonant component positioning plate 11 is connected between the connecting plates 7. The connecting plate 7 is a bent plate, and it has corresponding circular holes 701 and oblong holes 702. This structure makes the connecting plate 7 structurally stable.Meanwhile, the connecting plate 7 reliably fixes the resonant component positioning plate 11. The resonant component positioning plate 11 contacts and engages with the circuit board 9, and through holes for positioning the resonant component during welding are provided on the resonant component positioning plate 11. The clamping pad 501 and the anti-slip pad 301 are positioned correspondingly, and the lower end face of the clamping pad 501 is lower than the upper end face of the protrusion 304. This structure allows the side clamping plate 5 to clamp the circuit board 9 from the side through the clamping pad 501, ensuring the stable positioning of the circuit board 9. The resonant component positioning plate 11 is raised and lowered by the lifting drive mechanism 10, which allows the resonant component positioning plate 11 to press down and stabilize the circuit board 9, and allows the through holes on the resonant component positioning plate 11 to position the resonant component and restrict the welding area to avoid affecting other parts of the circuit board 9. The size of the resonant component positioning plate 11 is smaller than the size of the circuit board 9. The resonant component positioning plate 11 is designed according to the specific size of the circuit board 9, and the through holes on the resonant component positioning plate 11 are opened accordingly according to the designed position of the resonant component.

[0018] Working Principle: When using the photovoltaic filter resonant component welding fixture, the photovoltaic filter resonant component is first welded to the circuit board 9. The welding fixture body 1 positions the circuit board 9 from below the lifting drive mechanism 10 onto the positioning adjustment plate 3, supported by the protrusion 304. Anti-slip pads 301 provide anti-slip stability and scratch protection for the bottom of the circuit board 9. The positioning adjustment plate 3 is bent to ensure structural strength and uses weight-reducing holes 302 to reduce weight. After the circuit board 9 is placed, the transmission screw 4 is activated, causing the transmission screw 4, connecting rod 801, and limit rod 8 to rotate synchronously. This allows the side clamping plate 5 to move under the support of the recess 303, achieving stable clamping of the circuit board 9 by the clamping pad 501. The spacing between the three can be adjusted according to the specific dimensions of the circuit board 9. The positioning and stabilizing plate 6 adjusts and limits the positioning adjustment plate 3 through the limiting rod 8. By fixing the positioning and stabilizing plate 6 and the positioning adjustment plate 3 to the positioning base plate 2 respectively with bolts, the stability of the basic positioning of the welding fixture body 1 is ensured. While the transmission screw 4 is driven, the lifting drive mechanism 10 is started, so that the lifting drive mechanism 10 drives the resonant component positioning plate 11 to move down gradually, so that the resonant component positioning plate 11 presses the circuit board 9. The resonant component is welded and positioned through the through hole opened on the resonant component positioning plate 11 for the resonant component positioning. The connecting plate 7 fixes the resonant component positioning plate 11 through the cooperation of the round hole 701 and the oblong hole 702, thereby completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
