Description

Technical Field

[0001] The invention belongs to the technical field of electrical processing, and in particular relates to a welding inspection device for manganese-copper shunt strips. Background Art

[0002] Manganese copper shunt is a component used in power systems to shunt current and distribute electrical energy. In the production process of manganese copper shunt, two copper strips and one manganese copper strip need to be laser welded to form an integral strip, and then the strip is cut and stamped for use on the manganese copper shunt element. After the strip is welded, personnel need to check the strip, such as whether the welding point is between the welds, whether there are protrusions on both sides of the strip, and the size of the leakage beam, and mark the places where the welding quality does not meet the requirements so that they can be cut off and scrapped in subsequent processing. Therefore, when checking the welding points of the strip, personnel need to bend down and observe the upper and lower sides of the strip repeatedly, check the poor welding points and mark them. Because manganese copper and copper are dark in color and inconvenient to observe, it is also quite troublesome to mark the strips on the upper and lower sides. After marking, the marked parts of the strip need to be cleaned to prevent debris particles from being rolled in when the strip is rolled up, which seriously affects work efficiency.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] (1) The inspector can use the marking component to mark whether the welding points on the upper and lower surfaces of the manganese copper strip are between the welds, whether there are protrusions on both sides of the strip, and whether there are any welding discrepancies such as the size of the leaked beam. The V-shaped plate can drive the movable shaft to rotate, so that the upper marking part or the lower marking part is close to the manganese copper strip, so that it can be cut off and scrapped in subsequent processing. Since manganese copper and copper are dark in color and the longitudinal scratches on their surface are not convenient for observers to see, the support spring can be pressed to make the casing rotate around the connecting shaft. At this time, the rotating motor drives the marking drill rod to move horizontally on the manganese copper strip, leaving a wavy scratch, which is convenient for observers to cut off and scrap in subsequent processing.

[0016] (2) The cleaning card at the entrance window can be used to clean the manganese copper tape after welding to prevent the debris generated by welding from adhering to the surface of the manganese copper tape, which is not conducive to the inspection personnel to observe the surface of the tape; the cleaning card at the exit window can be used to clean the manganese copper tape after marking to prevent the debris particles generated during the marking of the tape from being rolled into the manganese copper tape when it is rolled up.

[0017] (3) The upper lighting device and the lower lighting device illuminate the upper surface of the manganese-bronze strip, making it convenient for inspectors to observe and inspect the manganese-bronze strip from above or below, and mark the places where the welding quality does not meet the standards through the upper marking parts of the marking assembly so that they can be cut off and scrapped in subsequent processing. Since inspectors stare at the manganese-bronze strip for a long time, the lampshade on the upper lighting device and the lower lighting device facing away from the inspectors can prevent the light from directly shining into the inspectors' eyes, thereby avoiding visual fatigue and eye damage.

[0018] (4) The inspector can directly observe through the left and right observation mirrors whether the welding points on the lower surface of the manganese-bronze strip are between the welds, whether there are protrusions on both sides of the strip, and the size of the leakage beam, and mark the places where the welding quality does not meet the requirements through the lower marking parts of the marking component. The observer does not need to bend down to observe the lower surface of the manganese-bronze strip, which improves the inspection efficiency and makes the work more convenient.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection.

[0030] In the description of the embodiments, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the embodiments.

[0031] Manganese copper shunt is a component used in power systems for shunting current and distributing electric energy. In the production process of manganese copper shunt, two copper strips and one manganese copper strip need to be laser welded to form an integral strip, and then the strip is cut and stamped for use on the manganese copper shunt element. After the strip is welded, personnel need to check the strip, such as whether the welding point is between the welds, whether there are protrusions on both sides of the strip, and the size of the leakage beam, and mark the places where the welding quality does not meet the requirements so that they can be cut off and scrapped in subsequent processing. However, the inventor of this application has realized that when checking the welding points of the strip, the staff needs to repeatedly observe the upper and lower sides of the strip, check the poor welding points and mark them. Since manganese copper and copper are dark in color and inconvenient to observe, it is also quite troublesome to mark the strips on the upper and lower sides. After marking, the marked parts of the strip need to be cleaned to avoid the inclusion of foreign particles when the strip is rolled up, which greatly affects the work efficiency.

[0032] After recognizing the above problems, the inventors of the present application proposed and disclosed a manganese-copper shunt strip welding inspection device, which can facilitate personnel to directly observe the upper and lower sides of the strip, flexibly mark poor welding areas, and clean the strip.

[0033] Referring to the accompanying drawings, Figure 1 and Figure 2 As shown, a manganese copper shunt strip welding inspection device comprises a movable frame 1 and a marking assembly 2, wherein one side of the movable frame 1 is provided with an inlet window 3, and the other side of the movable frame 1 is provided with an outlet window 4, wherein the inlet window 3 and the outlet window 4 are arranged opposite to each other on the same horizontal line, and when in use, the manganese copper strip 35 is introduced into the movable frame 1 through the inlet window 3 and is led out of the movable frame 1 through the outlet window 4, and the marking assembly 2 is fixedly arranged in the movable frame 1;

[0034] like Figure 3 and Figure 4 As shown, the marking assembly 2 includes a connecting plate 5, a movable shaft 6, a V-shaped plate 7, an upper marking member 8 and a lower marking member 9. The connecting plate 5 is fixedly arranged on the movable frame 1, and the connecting plate 5 and the inlet window 3 and the outlet window 4 are arranged on the same horizontal line. The movable shaft 6 is rotatably arranged on the connecting plate 5. The middle end of the V-shaped plate 7 is fixedly arranged on the movable shaft 6. Grooves 10 are arranged at both ends of the V-shaped plate 7. The upper marking member 8 is arranged in the groove 10 at the upper end of the V-shaped plate 7. The lower marking member 9 is arranged in the groove 10 at the lower end of the V-shaped plate 7. The upper marking member 8 and the lower marking member 9 are symmetrically arranged.

[0035] In this embodiment, the manganese-copper strip 35 is introduced into the movable frame 1 through the inlet window 3 and is led out of the movable frame 1 through the outlet window 4, and the manganese-copper strip 35 passes through the middle of the upper marking piece 8 and the lower marking piece 9. The inspector can control the V-shaped plate 7 to drive the movable shaft 6 to rotate so that the upper marking piece 8 or the lower marking piece 9 is close to the manganese-copper strip 35, and mark the parts of the upper and lower surfaces of the manganese-copper strip 35 that are not in compliance with the welding quality so that they can be cut off and scrapped in subsequent processing.

[0036] like Figure 3 and Figure 4 As shown, the upper marking member 8 includes a connecting shaft 11, a casing 12, a marking drill rod 13 and a first supporting spring 14, the connecting shaft 11 is fixedly arranged in the groove 10, the upper end of the casing 12 is movably arranged on the connecting shaft 11, a rotating motor 15 is arranged in the casing 12, the marking drill rod 13 is fixedly arranged on the output shaft end of the rotating motor 15, a fixing rod 16 is arranged on the outer wall of the casing 12, a protrusion 17 is arranged on the side wall of the V-shaped plate 7, and the protrusion 17 is arranged close to the fixing rod 16, one end of the first supporting spring 14 is fixedly arranged on the fixing rod 16, and the other end of the first supporting spring 14 is fixedly arranged on the protrusion 17, and the lower marking member 9 has the same structure as the upper marking member 8.

[0037] In this embodiment, the output shaft end of the rotating motor 15 drives the marking drill rod 13 to rotate, and the V-shaped plate 7 drives the movable shaft 6 to rotate, so that the marking drill rod 13 is close to the manganese-bronze strip 35, and the parts of the manganese-bronze strip 35 that do not meet the welding quality requirements are marked.

[0038] In this embodiment, since the manganese-copper tape 35 passes horizontally between the upper marking part 8 and the lower marking part 9, when the marking drill rod 13 contacts the manganese-copper tape 35, a longitudinal scratch will be left, and the longitudinal scratch is not convenient for observers to view. Therefore, the supporting spring can be pressed to make the housing 12 rotate around the connecting shaft 11. At this time, the rotating motor 15 drives the marking drill rod 13 to move horizontally on the manganese-copper tape, thereby leaving a wavy scratch, which is convenient for observers to cut off and scrap in subsequent processing.

[0039] like Figure 3 and Figure 4 As shown, a handle 18 is provided at the upper end of the upper marking member 8 , and the handle 18 is provided at the upper end of the housing 12 , so that the user can drive the V-shaped plate 7 and the movable shaft 6 to rotate through the handle 18 .

[0040] In this embodiment, when it is necessary to mark above the manganese-bronze tape 35, the handle 18 is pressed down so that the marked drill rod 13 of the upper marking part 8 is close to the manganese-bronze tape 35 for marking. When it is necessary to mark below the manganese-bronze tape 35, the handle 18 is pulled up so that the marked drill rod 13 of the lower marking part 9 is close to the manganese-bronze tape 35 for marking.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, a support plate 19 is provided at the lower end of the V-shaped plate 7, and the support plate 19 is arranged close to the lower marking member 9. A support seat 20 is provided below the support plate 19, and the support seat 20 is arranged on the lower wall of the movable frame 1. A second support spring 21 is provided on the support seat 20, and the lower end of the second support spring 21 is fixedly arranged against the support seat 20, and the upper end of the second support spring 21 is fixedly arranged against the support plate 19.

[0042] In this embodiment, the support seat 20, the second support spring 21 and the support plate 19 jointly support the V-shaped plate 7, so that the distances between the upper marking member 8 and the lower marking member 9 and the manganese-bronze strip 35 are close. In the absence of user operation, the marking drill rod 13 will not touch the manganese-bronze strip 35 due to the natural support of the second support spring 21.

[0043] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a cleaning card 22 is clamped on the outer side of the inlet window 3 and the inner side of the outlet window 4. The cleaning card 22 includes a clamping frame 23, a fixing plate 24 and a cleaning cloth 25. A clamping portion 26 is provided on one end of the clamping frame 23. The clamping frame 23 is clamped on the inlet window 3 and the outlet window 4 through the clamping portion 26. The fixing plate 24 is provided on the other end of the clamping frame 23 away from the clamping portion 26. Two groups of fixing plates 24 are provided, and the two groups of fixing plates 24 are symmetrically arranged up and down. The cleaning cloth 25 is fixed on the fixing plate 24.

[0044] In this embodiment, the manganese-copper tape 35 is movably arranged between two groups of cleaning cloths 25, and the cleaning clamp 22 at the entrance window 3 can clean the welded manganese-copper tape 35 to prevent debris generated by welding from adhering to the surface of the manganese-copper tape 35, which is not conducive to the inspector's observation of the tape surface.

[0045] In this embodiment, the cleaning card 22 at the outlet window 4 can clean the marked manganese-bronze tape 35 to prevent debris particles generated during marking from being rolled into the manganese-bronze tape 35 when it is rolled up.

[0046] like Figure 1 and Figure 2 As shown, an upper lighting device 27 is symmetrically provided inside the movable frame 1 , and the upper lighting device 27 is provided above the entrance window 3 and the exit window 4 . A lampshade 28 is provided on the upper lighting device 27 , and the lampshade 28 is provided above the upper lighting device 27 .

[0047] In this embodiment, the upper lighting device 27 emits light to illuminate the upper surface of the manganese-bronze strip 35, so that the inspectors can observe and inspect the manganese-bronze strip 35 from above, such as whether the welding points are between the welds, whether there are protrusions on both sides of the strip, and the size of the leakage beam, etc., and mark the places where the welding quality does not meet the requirements through the upper marking part 8 of the marking component 2, so that they can be cut off and scrapped in subsequent processing. Since the inspectors stare at the manganese-bronze strip 35 for a long time, the lampshade 28 provided on the upper lighting device 27 can prevent the upper lighting device 27 from directly irradiating the inspectors' eyes to avoid visual fatigue and eye damage.

[0048] like Figure 1 and Figure 2 As shown, the lower wall of the movable frame 1 is provided with a lower lighting device 29, which is arranged at the front end of the marking component 2, and the light-emitting end of the lower lighting device 29 is arranged toward the marking component 2, and the upper lighting device 27 and the lower lighting device 29 are both energy-saving lamps.

[0049] In this embodiment, the lower lighting device 29 can emit light to illuminate the lower surface of the manganese-bronze strip 35, so that the inspectors can observe and inspect the manganese-bronze strip 35 from below, such as whether the welding points are between the welds, whether there are protrusions on both sides of the strip, and the size of the leakage beam, etc., and mark the places where the welding quality does not meet the requirements through the lower marking part 9 of the marking component 2, so that they can be cut off and scrapped in subsequent processing. The lower lighting device 29 is facing away from the inspectors to avoid the light irradiating the inspectors' eyes and causing visual fatigue and eye damage.

[0050] like Figure 1 and Figure 2 As shown, a left observation mirror 30 and a right observation mirror 31 are provided in the movable frame 1. The left observation mirror 30 is provided on the left side of the marking component 2, and the left observation mirror 30 is inclined to the left rearward, and the right observation mirror 31 is provided on the right side of the marking component 2, and the right observation mirror 31 is inclined to the right rearward.

[0051] In this embodiment, the observer can directly observe whether the welding points on the lower surface of the manganese-bronze strip 35 are between the welds, whether there are protrusions on both sides of the strip, and the size of the leakage beam through the left observation mirror 30 and the right observation mirror 31, and mark the places where the welding quality is inconsistent through the lower marking part 9 of the marking component 2. The observer does not need to bend down to observe the lower surface of the manganese-bronze strip 35, so the inspection efficiency is improved and the work is more convenient.

[0052] like Figure 1 , Figure 5 and Figure 8 As shown, a base 32 is provided at the lower end of the movable frame 1, a slider 33 is provided on the lower wall of the movable frame 1, a slide groove 34 is provided on the base 32, and the slide groove 34 is matched with the slider 33 in size. The movable frame 1 is slidably arranged on the base 32 through the slider 33.

[0053] In this embodiment, since the manganese-copper strip 35 passes through the marking component 2 at a uniform speed, when the upper and lower surfaces of the manganese-copper strip 35 have welding quality discrepancies at the same time, the marking component 2 cannot mark the upper and lower surfaces at the same time. At this time, the inspector can move the movable frame 1 along the direction of the slide groove 34 to make the marking component 2 close to the manganese-copper strip 35, and mark the parts that have not been marked in time, so that the inspector can cut them off and scrap them in subsequent processing.

[0054] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] Although embodiments have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the embodiments is defined by the appended claims and their equivalents.

[0056] The above description of the implementation mode is not restrictive, and the drawings show only one of the implementation modes, and the actual structure is not limited thereto.
