Description

Technical Field

[0001] The invention relates to the technical field of transformer manufacturing, in particular to a copper busbar positioning device for processing a micro transformer. Background Art

[0002] Accurate positioning can ensure that the distance between copper bars and between copper bars and other conductive parts meets the design requirements, avoiding the situation where the distance is too small to cause a short circuit, or the distance is too large to affect the electric field distribution and electromagnetic performance. Taking a small electronic transformer as an example, if the copper bar is not accurately positioned, the coupling coefficient between the windings may change, affecting the transformer's transformation ratio and efficiency and other performance indicators. At the same time, the positioning equipment can achieve fast and accurate positioning, reducing the time for manual measurement and adjustment, and improving production efficiency. When mass-producing transformers, the use of positioning equipment can ensure that the position of the copper bar in each product is consistent, which is convenient for automated production and quality control;

[0003] During the positioning process, the existing equipment is unable to pre-fix the copper busbar plate, resulting in slight movement of the plate during the fixing process after positioning, causing the staff to position it again, reducing positioning efficiency. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A copper busbar positioning device for processing a micro transformer, comprising:

[0006] A frame, a cross plate is fixedly mounted on the top of the frame, and slots are symmetrically provided on the top of the cross plate;

[0007] A side lift mechanism, which is installed inside the frame and is symmetrically installed along the center position of the axis of the frame;

[0008] A supporting mechanism, which is installed at the bottom of the side top mechanism opposite to the side top mechanism, and the supporting mechanism cooperates with the side top mechanism to fix the copper busbar raw material;

[0009] The clamping plate of the cross plate is detachably mounted at the clamping groove of the cross plate, and a screw ring is fixedly mounted at the center position of the top of the clamping plate, and a stud is threadedly connected to the inner wall of the screw ring, and the bottom end of the stud penetrates the clamping plate and extends to its bottom, and a connecting plate is rotatably mounted on the bottom end of the stud, and connecting beams are fixedly mounted on both sides of the connecting plate, and the connecting beams are symmetrically mounted along the center position of the axis of the connecting plate, and an inclined panel is fixedly mounted on the bottom of the connecting beam, and the position of the copper bar plate is positioned by contacting the top edge position of the copper bar plate through the inclined surface of the inclined panel. When both sides of the copper bar plate contact the inclined panel, the plate is positioned, and when the positions of the two sides of the plate contacting the inclined panel are at the same height, the positioning is completed, and at the same time, the inclined panel applies pressure on the top of the plate to pre-fix the plate to avoid the plate from being offset again when it is fixed by the side top mechanism and the supporting mechanism, and the bottom of the inclined panel is an inclined surface inclined downward away from the connecting plate.

Through the cooperation of the springs on both sides, when the plate is placed, the two sides of the plate are deformed according to their own width through the zigzag plate compression spring. After placing the plate, the spring is deformed by the same distance under the same elastic force, so that the center position of the plate is the same as the position of the zigzag plate, thereby completing the positioning of the copper bus plate and improving the positioning efficiency. A screw hole is opened at the center position of the top of the zigzag plate, and sliding holes are opened on both sides of the top of the zigzag plate.

The bottom of the strip is lower than the bottom of the pressing plate, and the rubber strip is located on both sides of the pressing plate. The bottom of the opposite surface of the rubber strip is an inclined surface inclined from top to bottom on both sides. The rubber strip cooperates with the pressing plate to make the rubber strip contact the plate first, and then the pressing plate contacts the plate, so that the rubber strip deforms under the contact pressure, increasing the contact area, increasing the friction force, and improving the fixing effect. At the same time, the inclined surfaces between the rubber strips provide deformation space for the deformation of the rubber strip, thereby avoiding blocking the contact between the pressing plate and the plate when the rubber strip is deformed, resulting in a reduction in the fixing effect.

[0012] Preferably, the support mechanism comprises a support plate, the outer side of the support plate is fixedly connected to the bottom of the opposite side of the flexural plate, the top of the support plate is provided with a rectangular through groove, the bottom of the support plate is fixedly installed with a slide block, the slide block is symmetrically installed on the bottom of the support plate along the axis center position of the rectangular through groove, the outer side of the slide block is provided with a slide groove, and a slide rod is slidably installed at the slide groove of the slide block, the top of the support plate is fixedly installed with an inclined groove plate, the outer side of the slide rod is rotatably installed with a rotating wheel, the outer side of the rotating wheel is provided with an annular groove, and the rubber ring and the rotating wheel are used to cooperate with each other to change the sliding friction force of the plate during longitudinal movement into rotating friction force when the plate is positioned, thereby reducing the resistance encountered by the plate during movement, and cooperating with the inclined plate , so that the copper bar plate can move smoothly during positioning, thereby improving the positioning efficiency, and a rubber ring is fixedly installed at the annular groove of the rotating wheel, and an elastic pad is clamped at the slide groove of the slide block, and the top of the elastic pad is in contact with the two ends of the bottom of the slide rod, and the top of the inclined slot plate is evenly provided with inclined slots, and through the cooperation of the inclined slot plate and the elastic pad, during the fixing process, the elastic pad is gradually deformed and compressed under pressure, so that the inclined slot plate gradually contacts the copper bar plate, and the contact between the inclined slot plate and the pressing plate is utilized to complete the fixing of the plate, so that the plate can be finely adjusted before being completely fixed, and fine-tuning can be performed when there is a slight deviation in the center position, thereby improving the positioning efficiency, and the inclined slot plate is located directly below the pressing plate, and the top of the rubber ring is higher than the top of the inclined slot plate.

[0013] The present invention provides a copper busbar positioning device for processing a micro transformer, which has the following beneficial effects:

[0014] 1. The copper bar positioning equipment for processing the micro transformer locates the copper bar plate by contacting the inclined surface of the inclined plate with the top edge of the copper bar plate. When both sides of the copper bar plate contact the inclined plate, the plate is positioned. When the positions of both sides of the plate contacting the inclined plate are at the same height, the positioning is completed. At the same time, the inclined plate applies pressure to the top of the plate to pre-fix the plate to avoid the plate from shifting again when it is fixed by the side top mechanism and the support mechanism.

[0015] 2. The copper busbar positioning equipment processed by the micro-transformer cooperates with the springs on both sides. When the plate is placed, the two sides of the plate are deformed according to their own width through the zigzag plate compression springs. After placement, the springs are deformed the same distance under the same elastic force, so that the center position of the plate is the same distance from the zigzag plate, completing the positioning of the copper busbar plate and improving the positioning efficiency.

[0016] 3. The copper bar positioning equipment for processing the micro transformer cooperates with the rubber strip and the pressing plate, so that the rubber strip contacts the plate first, and then the pressing plate contacts the plate, so that the rubber strip is deformed under the contact pressure, increasing the contact area, increasing the friction, and improving the fixing effect. At the same time, the inclined surface between the rubber strips provides deformation space for the deformation of the rubber strip, avoiding the rubber strip from blocking the contact between the pressing plate and the plate when deforming, resulting in a reduction in the fixing effect.

[0017] Fourth, the copper bar positioning equipment processed by the micro-transformer, through the cooperation of the rubber ring and the rotating wheel, when locating the position of the plate, the sliding friction force of the plate during longitudinal movement is converted into rotational friction, thereby reducing the resistance encountered by the plate during movement, and cooperating with the inclined plate, the copper bar plate can move smoothly during positioning, thereby improving the positioning efficiency.

[0018] 5. The copper busbar positioning equipment for processing the micro-transformer, through the cooperation of the inclined slot plate and the elastic pad, in the process of fixing, makes the elastic pad gradually deform and compress under pressure, so that the inclined slot plate gradually contacts the copper busbar plate, and utilizes the contact between the inclined slot plate and the pressing plate to complete the fixing of the plate, so that the plate can be slightly adjusted before being completely fixed, and fine-tuning can be performed when there is a slight deviation in the center position, thereby improving the positioning efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution:

[0030] A copper busbar positioning device for processing a micro transformer, comprising:

[0031] Frame 1, a cross plate 4 is fixedly mounted on the top of the frame 1, and a card slot is symmetrically opened on the top of the cross plate 4;

[0032] A side lift mechanism 2, which is installed inside the frame 1, and the side lift mechanism 2 is symmetrically installed along the center position of the axis of the frame 1;

[0033] A support mechanism 3, which is installed at the bottom of the side top mechanism 2, and the support mechanism 3 cooperates with the side top mechanism 2 to fix the copper busbar raw material;

[0034] A card plate 6 is detachably installed at the card slot of the cross plate 4, a screw ring 10 is fixedly installed at the center position of the top of the card plate 6, a stud 7 is threadedly connected to the inner wall of the screw ring 10, the bottom end of the stud 7 passes through the card plate 6 and extends to its bottom, and a connecting plate 5 is rotatably installed at the bottom end of the stud 7, and connecting beams 8 are fixedly installed on both sides of the connecting plate 5. After the card plate 6 and the cross plate 4 are connected, the worker rotates the stud 7 with a wrench, utilizes the threaded connection between the stud 7 and the screw ring 10, and cooperates with the rotation connection between the stud 7 and the connecting plate 5 to drive the connecting plate 5 to move downward, so that during the downward movement of the connecting plate 5, the connecting beam 8 is driven to move downward synchronously, and then during the movement, the inclined panel 9 at the bottom of the connecting beam 8 contacts the copper bar plate. When in contact, the inclined surface of the bottom of the inclined panel 9 contacts the edge position of the top of the copper bar plate. When the edge positions on both sides of the plate are at the same height as the contact position of the inclined surface of the inclined panel 9, the longitudinal center position is positioned, and the side top mechanism 2 is used to coordinate the lateral positioning of the plate so that the copper bar plate corresponds to the center position of the frame 1 to complete the positioning. The connecting beam 8 is symmetrically installed along the center position of the axis of the connecting plate 5, and the bottom of the connecting beam 8 is fixedly installed with an inclined panel 9. The plate after positioning is fixed by the side top mechanism 2 and the supporting mechanism 3. Then, according to the needs of processing, the clamping plate 6 and the cross plate 4 can be released, and the obstruction on the top of the plate can be removed. The bottom of the inclined panel 9 is an inclined surface that is inclined downward away from the connecting plate 5.

[0035] The second embodiment is based on the first embodiment. Figures 5 and 6 As shown, the side top mechanism 2 includes a zigzag plate 21, a sliding shaft 22 is fixedly installed on the outer side of the zigzag plate 21, and the sliding shaft 22 is symmetrically installed along the center position of the axis of the zigzag plate 21. A spring 24 is fixedly installed between the zigzag plate 21 and the frame 1, and the spring 24 is located on the outer side of the sliding shaft 22. When the plate is placed, the bottom of the plate is supported by the support mechanism 3, and the opposite surface of the zigzag plate 21 contacts the side of the plate. At the same time, the zigzag plate 21 is pushed to both sides according to the width of the plate, so that the zigzag plate 21 compresses the spring 2 4. Then, through the elastic force of the spring 24 after deformation, the same elastic force of the springs 24 on both sides pushes the flex plate 21 to contact the plate, so that the springs 24 on both sides are deformed to the same extent, so that the center position of the plate is the same distance from the flex plates 21 on both sides, completing the positioning of the horizontal center position, a screw hole is opened at the center position of the top of the flex plate 21, and sliding holes are opened on both sides of the top of the flex plate 21, and a screw rod 23 is threadedly connected to the screw hole of the flex plate 21, and a bottom plate 27 is rotatably installed at the bottom end of the screw rod 23.

[0036] A connecting rod 26 is fixedly installed on the top of the bottom plate 27. The connecting rod 26 is symmetrically installed along the center position of the axis of the bottom plate 27, and the outer side of the connecting rod 26 is slidably adapted to the sliding hole of the zigzag plate 21. The top of the connecting rod 26 passes through the zigzag plate 21 and extends to its top, and a limit block 25 is fixedly installed on the top of the connecting rod 26. A pressing plate 28 is fixedly installed at the center position of the bottom of the bottom plate 27, and a rubber pressure strip 29 is fixedly installed at the bottom of the bottom plate 27. The rubber pressure strip 29 is symmetrically installed along the center position of the axis of the bottom plate 27, and the bottom of the pressing plate 28 is evenly provided with oblique protrusions along the axial direction. During the process, a worker rotates the screw rod 23 and utilizes the threaded connection between the screw rod 23 and the screw hole of the flex plate 21 to drive the bottom plate 27 to move downward, so that the bottom plate 27 moves vertically downward under the restriction of the connecting rod 26. During the downward movement, the bottom of the rubber strip 29 first contacts the top of the plate, and then continues to move downward. Under the contact pressure, the rubber strip 29 is deformed and compressed until the pressing plate 28 contacts the plate, and then the fixation is completed. The bottom of the rubber strip 29 is lower than the bottom of the pressing plate 28, and the rubber strip 29 is located on both sides of the pressing plate 28. The bottom of the opposite surface of the rubber strip 29 is an inclined surface inclined from top to bottom to both sides.

[0037] The third embodiment is based on the first and second embodiments. Figures 7 and 8 As shown, the supporting mechanism 3 includes a supporting plate 31, the outer side of the supporting plate 31 is fixedly connected to the bottom of the opposite side of the zigzag plate 21, a rectangular through groove is provided on the top of the supporting plate 31, a slide block 32 is fixedly installed on the bottom of the supporting plate 31, and the slide block 32 is symmetrically installed on the bottom of the supporting plate 31 along the axial center position of the rectangular through groove. When the plate is put in, the rubber ring 35 at the ring groove of the rotating wheel 36 contacts the bottom of the plate. In the process of adjusting the position of the plate for positioning by the inclined plate 9, the rotating wheel 36 is connected with the sliding rod 33 through rotation, and the sliding friction force is converted into a rotating friction force, thereby ensuring the smooth longitudinal movement of the plate and reducing the difficulty of positioning. A slide groove is provided on the outer side of the slide groove block 32, and a slide rod 33 is slidably installed at the slide groove of the slide groove block 32, and an inclined groove plate 37 is fixedly installed on the top of the supporting plate 31.

[0038] The outer side of the slide bar 33 is rotatably mounted with a rotating wheel 36, the outer side of the rotating wheel 36 is provided with an annular groove, and a rubber ring 35 is fixedly mounted at the annular groove of the rotating wheel 36, and the slide groove of the slide groove block 32 is clamped with elastic pads 34, and the top of the elastic pads 34 contacts the two ends of the bottom of the slide bar 33. In the process of fixing the plate, the downward pressure of the plate by the side top mechanism 2 is caused to transfer the pressure to the slide bar 33 through the rubber ring 35 and the rotating wheel 36, so that the slide bar 33 slides downward in the slide groove of the slide groove block 32, compressing the elastic pad 34 to deform, so that the inclined slot plate 37 gradually contacts the bottom of the plate, and cooperates with the pressing plate 28 in the side top mechanism 2 to complete the fixing of the plate. The top of the inclined slot plate 37 is evenly provided with inclined slots, and the inclined slot plate 37 is located directly below the pressing plate 28, and the top of the rubber ring 35 is higher than the top of the inclined slot plate 37.

[0039] When in use, the staff first unfastens the clamping plate 6 and the cross plate 4, then puts the copper bar plate into the side top mechanism 2, and supports the plate through the support mechanism 3, and laterally positions the plate through the side top mechanism 2 so that the center position of the plate is between the side top mechanism 2, and then clamps and fixes the clamping plate 6 and the cross plate 4, and longitudinally positions the plate so that the center position of the plate corresponds to the center position of the frame 1 to complete the positioning. After the fixation is completed, the worker fixes the copper bar plate by operating the side top mechanism 2 and the support mechanism 3.

[0040] After the clamping plate 6 and the cross plate 4 are connected, the worker turns the stud 7 with a wrench, and uses the threaded connection between the stud 7 and the screw ring 10, in conjunction with the rotation connection between the stud 7 and the connecting plate 5, to drive the connecting plate 5 to move downward, so that during the downward movement of the connecting plate 5, the connecting beam 8 is driven to move downward synchronously. Subsequently, during the movement, the inclined plate 9 at the bottom of the connecting beam 8 contacts the copper bar plate. During the contact, the inclined surface at the bottom of the inclined plate 9 contacts the edge position at the top of the copper bar plate. When the edge positions on both sides of the plate are at the same height as the contact position of the inclined surface of the inclined plate 9, the longitudinal center position is positioned, and the side top mechanism 2 cooperates with the lateral positioning of the plate to make the copper bar plate correspond to the center position of the frame 1 to complete the positioning. Subsequently, the side top mechanism 2 cooperates with the supporting mechanism 3 to fix the positioned plate. Subsequently, according to the needs during processing, the clamping plate 6 and the cross plate 4 can be released from the clamping plate, and the obstruction on the top of the plate can be removed.

[0041] When a plate is placed in the side top mechanism 2, the bottom of the plate is supported by the supporting mechanism 3, and the opposite surface of the curved plate 21 contacts the side of the plate. At the same time, the curved plate 21 is pushed to both sides according to the width of the plate, so that the curved plate 21 compresses the spring 24, and then the elastic force after the deformation of the spring 24 is used, and the same elastic force of the springs 24 on both sides pushes the curved plate 21 to contact the plate, so that the springs 24 on both sides are deformed to the same extent, so that the center position of the plate is the same distance from the curved plates 21 on both sides, and the positioning of the lateral center position is completed. In the process of fixing the plate, the worker rotates the screw rod 23 and utilizes the threaded connection between the screw rod 23 and the screw hole of the curved plate 21 to drive the bottom plate 27 to move downward, so that the bottom plate 27 moves vertically downward under the restriction of the connecting rod 26. In the process of moving downward, the bottom of the rubber strip 29 first contacts the top of the plate, and then continues to move downward. Under the contact pressure, the rubber strip 29 is deformed and compressed until the pressing plate 28 contacts the plate and the fixation is completed.

[0042] In the support mechanism 3, when the plate is put in, the rubber ring 35 at the ring groove of the rotating wheel 36 contacts the bottom of the plate. In the process of adjusting the position of the plate for positioning by the inclined plate 9, the rotating connection between the rotating wheel 36 and the slide rod 33 converts the sliding friction force into a rotating friction force, thereby ensuring the smooth longitudinal movement of the plate and reducing the difficulty of positioning. In the process of fixing the plate, the downward pressure of the plate by the side top mechanism 2 causes the plate to transfer the pressure to the slide rod 33 through the rubber ring 35 and the rotating wheel 36, so that the slide rod 33 slides down in the slide groove of the slide groove block 32, compressing the elastic pad block 34 to deform, so that the inclined groove plate 37 gradually contacts the bottom of the plate and cooperates with the pressure plate 28 in the side top mechanism 2 to complete the fixation of the plate.
