Description

Technical Field

[0001] The utility model relates to the technical field of new energy, and particularly relates to a busbar stripping device. Background Art

[0002] New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. Generally, it refers to renewable energy developed and utilized on the basis of new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy, tidal energy, and the thermal cycle between the ocean surface and deep layers. New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels and adopt new in-vehicle power devices), and integrate advanced technologies in the power control and drive aspects of vehicles, forming vehicles with advanced technical principles, new technologies, and new structures. Common new energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. In new energy vehicles with an electric drive mode, wires for transmitting electric energy are required, and generally flat copper busbars and aluminum busbars are used. Taking the copper busbar as an example, during the production and processing of the copper busbar, an insulating layer needs to be coated on the outside of the conductor. After the copper busbar is processed into the designed shape, in order to facilitate electrical connection during subsequent use, a certain length of the insulating layer at the end of the copper busbar needs to be stripped to expose the end of the copper busbar. The traditional operation is for workers to use tools to cut the insulating layer outside the busbar and then peel off the cut insulating layer. Such a method has a high intensity and low efficiency.

[0007] Further, the tool holder is provided with a mounting hole for mounting the wire pushing tool, and a plurality of fixing holes are provided at the top of the tool holder. The fixing holes communicate with the mounting hole.

Specific embodiments

[0024] For the convenience of those skilled in the art to understand the present utility model, the present utility model will be further described in detail below in conjunction with specific embodiments and drawings.

[0025] Embodiment 1

[0026] Referring to Figures 1 to 5 , the present utility model provides a busbar stripping device, including a chassis, a support frame provided on the chassis, a wire clamping mechanism provided on the support frame, and a wire pushing mechanism provided on the chassis; the wire clamping mechanism includes an upper wire clamping assembly connected to the support frame, a lower wire clamping assembly connected to the support frame and matching with the upper wire clamping assembly, and a drive assembly for driving the upper wire clamping assembly and the lower wire clamping assembly to approach or separate from each other. In this embodiment, the chassis has a bottom plate, and the support frame and the wire pushing mechanism are both provided on the bottom plate. The support frame specifically includes a support vertical plate and a reinforcing plate. When stripping the copper bar busbar, the upper wire clamping assembly and the lower wire clamping assembly clamp the copper bar busbar from the upper and lower sides, and the wire pushing mechanism pushes the copper core part to move. At this time, the insulating layer is clamped and extruded, so that the insulating layer can be clamped and stripped.

[0027] The upper clamp assembly and the lower clamp assembly both include a moving seat connected to the support frame and a clamping seat connected to the moving seat; the end surface of the clamping seat is provided with a plurality of protrusions contacting the busbar. The clamping seat is connected to the support frame through a guide rail slider assembly, the clamping seat of the upper clamp assembly is arranged at the bottom of the moving seat, and the clamping seat of the lower clamp assembly is arranged at the top of the moving seat, and the upper and lower clamping seats are positioned relative to each other, that is, the upper clamp assembly and the lower clamp assembly are symmetrically arranged.

[0028] The wire pushing mechanism includes a moving block movably connected to the chassis, a knife seat arranged on the moving block, a push knife connected to the knife seat, a first lead screw arranged on the chassis, and a first driving member for driving the first lead screw, the first lead screw is connected to the moving block and drives the moving block to approach or move away from the wire clamping mechanism. The first driving member drives the first lead screw to rotate, so that the moving block moves toward the support frame, the push knife contacts the copper core of the copper busbar, and pushes the copper busbar to move outward.

[0029] The knife seat is provided with a mounting hole for mounting the push knife, and a plurality of fixing holes are provided on the top of the knife seat, and the fixing holes are connected with the mounting hole. In this embodiment, the mounting hole is a square hole, and one end of the push knife is inserted into the square hole. The mounting hole can be used to install a fastener, so as to lock the push knife on the knife seat.

[0030] The support frame is provided with a knife sleeve matching the push knife, and the push knife passes through the knife sleeve. The knife sleeve can guide the push knife, making the push knife more stable during movement, and ensuring that the push knife position will not be offset.

[0031] Several of the protrusions are arranged in multiple rows, and the protrusions between two adjacent rows are staggered, that is, each row has multiple protrusions arranged at equal intervals, and the protrusions of adjacent rows are staggered. When the upper clamping assembly and the lower clamping assembly clamp the copper busbar, the protrusions of the upper clamping seat and the protrusions of the lower clamping seat contact the copper busbar from both sides of the copper busbar, respectively, and squeeze the insulation layer of the copper busbar. With the cooperation of the push knife mechanism, the clamped part of the insulation layer is squeezed and pulled at the same time, thereby breaking and separating. In this embodiment, the protrusion is a square body, the contact area between the protrusion and the insulation layer is relatively small, and the local pressure is strong, so that the insulation layer can be broken during squeezing.

[0032] The driving assembly includes a second lead screw arranged on the support frame along a vertical direction, and a second driving member arranged on the support frame for driving the second lead screw; the second lead screw is connected to the moving seat. The second lead screw is a bidirectional lead screw, and when the second lead screw rotates, the upper clamping assembly and the lower clamping assembly move closer to or farther from each other.

[0033] The moving seat of the lower wire clamping assembly is provided with a positioning member. The positioning member includes a connecting portion connected to the moving seat, and two positioning portions provided on the connecting portion. The two positioning portions extend above the wire clamping seat, and there is an interval for accommodating the bus bar between the two positioning portions. During wire stripping, the bus bar is placed in this interval, and the positioning member can ensure the corresponding positions of the bus bar and the pushing tool.

[0034] One side of the moving seat facing the support frame is provided with a groove. When the pushing tool pushes the copper bus bar, it pushes the copper core part. As the pushing tool moves, the pushing tool inserts into the insulating layer at the end portion, and the stripped insulating layer adheres to the pushing tool. When the pushing tool resets and retracts into the tool sleeve, after the adhered insulating layer is disengaged from the tool sleeve, it separates from the pushing tool and falls from the groove.

[0035] The chassis is provided with a controller which has a touch display screen and can set operation parameters and display operation status.

[0036] During specific operation, the copper bus bar is placed on the wire clamping seat of the lower wire clamping assembly by a manipulator or manually. The driving assembly drives the upper wire clamping assembly and the lower wire clamping assembly to approach each other until the upper and lower wire clamping seats contact the copper bus bar. The insulating layer deforms under extrusion. At this time, the wire pushing mechanism pushes the copper bus bar to move outward, and the insulating layer is simultaneously squeezed and pulled to break. As the copper bus bar moves, the broken part of the insulating layer separates from the copper bus bar, thereby realizing the stripping of the insulating layer at the end of the copper bus bar.

In this embodiment, the chassis has a bottom plate, and the support frame and the wire pushing mechanism are both provided on the bottom plate. The support frame specifically includes a support vertical plate and a reinforcing plate. When the copper bus bar is stripped of its insulation, the upper wire clamping assembly and the lower wire clamping assembly clamp the copper bus bar from the upper and lower sides, and the wire pushing mechanism pushes the copper core part to move. At this time, the insulating layer is clamped and extruded, so that the insulating layer can be clamped and broken off.

[0039] Both the upper wire clamping assembly and the lower wire clamping assembly include a moving seat connected to the support frame and a wire clamping seat connected to the moving seat; a plurality of protruding portions in contact with the busbar are provided on the end face of the wire clamping seat. The wire clamping seat is connected to the support frame through a guide rail slider assembly. The wire clamping seat of the upper wire clamping assembly is arranged at the bottom of the moving seat, and the wire clamping seat of the lower wire clamping assembly is arranged at the top of the moving seat. Moreover, the positions of the upper and lower wire clamping seats are opposite to each other, that is, the upper wire clamping assembly and the lower wire clamping assembly are symmetrically arranged.

[0040] The wire pushing mechanism includes a moving block movably connected to the chassis, a tool holder arranged on the moving block, a pushing tool connected to the tool holder, a first lead screw arranged on the chassis, and a first driving member for driving the first lead screw. The first lead screw is connected to the moving block and drives the moving block to approach or move away from the wire clamping mechanism. The first driving member drives the first lead screw to rotate, so that the moving block moves towards the support frame, the pushing tool contacts the copper core of the copper bar busbar, and pushes the copper bar busbar to move outward.

[0041] The tool holder is provided with a mounting hole for mounting the pushing tool, and a plurality of fixing holes are arranged at the top of the tool holder. The fixing holes communicate with the mounting hole. In this embodiment, the mounting hole is a square hole, and one end of the pushing tool is inserted into the square hole. The mounting hole can be used to mount fasteners to lock the pushing tool on the tool holder.

[0042] A tool sleeve matching the pushing tool is arranged on the support frame, and the pushing tool passes through the tool sleeve. The tool sleeve can guide the pushing tool to make the pushing tool more stable during the movement and ensure that the position of the pushing tool will not shift.

[0043] The plurality of protruding portions are arranged in multiple rows, and the protruding portions between adjacent rows are staggered, that is, a plurality of protruding portions are arranged at equal intervals in each row, and the protruding portions of adjacent rows are staggered. When the upper wire clamping assembly and the lower wire clamping assembly clamp the copper bar busbar, the protruding portions of the upper wire clamping seat and the protruding portions of the lower wire clamping seat respectively contact the copper bar busbar from both sides of the copper bar busbar and squeeze the insulating layer of the copper bar busbar. With the cooperation of the wire pushing mechanism, the clamped part of the insulating layer is simultaneously squeezed and pulled, so as to break and separate.

[0044] The driving assembly includes a second lead screw arranged vertically on the support frame and a second driving member arranged on the support frame for driving the second lead screw; the second lead screw is connected to the moving seat. The second lead screw is a bidirectional lead screw. When the second lead screw rotates, the upper clamping assembly and the lower clamping assembly approach or move away from each other.

[0045] The moving seat of the lower wire clamping assembly is provided with a positioning member, which includes a connecting portion connected to the moving seat, two positioning portions provided on the connecting portion, the two positioning portions extend above the wire clamping seat, and there is an interval for accommodating the bus bar between the two positioning portions. During wire stripping, the bus bar is placed in this interval, and the positioning member can ensure the corresponding positions of the bus bar and the pushing knife.

[0046] A groove is provided on one side of the moving seat facing the support frame. When the pushing knife pushes the copper bus bar, it pushes the copper core part. As the pushing knife moves, the pushing knife inserts into the insulating layer at the end portion, and the stripped insulating layer adheres to the pushing knife. When the pushing knife resets and retracts into the knife sheath, after the adhered insulating layer is released from the knife sheath, it separates from the pushing knife and falls from the groove.

[0047] The chassis is provided with a controller, which has a touch display screen and can set operation parameters and display operation status.

[0048] During specific operation, the copper bus bar is placed on the wire clamping seat of the lower wire clamping assembly by a manipulator or manually. The driving assembly drives the upper wire clamping assembly and the lower wire clamping assembly to approach each other until the upper and lower wire clamping seats contact the copper bus bar, and the insulating layer deforms under extrusion. At this time, the wire pushing mechanism pushes the copper bus bar to move outward, and the insulating layer is simultaneously squeezed and pulled to break. As the copper bus bar moves, the broken part of the insulating layer separates from the copper bus bar, thus realizing the stripping of the insulating layer at the end of the copper bus bar.

[0049] The wire clamping mechanism of the present utility model includes an upper wire clamping assembly and a lower wire clamping assembly, which can clamp the bus bar from the upper and lower sides. With the cooperation of the wire pushing mechanism, the insulating layer at the end of the bus bar is simultaneously squeezed and pulled, thus breaking and separating from the bus bar. Only by placing the bus bar on the lower wire clamping assembly can rapid wire stripping be realized, improving the operation efficiency and reducing the labor intensity. At the same time, the raised portion provided in this application can reduce the contact area between the wire clamping seat and the insulating layer, thereby increasing the pressure to ensure that the insulating layer breaks during the movement of the bus bar and ensuring the effective separation of the insulating layer at the end.
