Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing opening technology, and in particular to an opening device for copper busbar heat shrink tubing. Background Technology

[0002] Copper busbar heat shrink tubing is a specially formulated heat shrink tubing made of polyolefin material, primarily used for the insulation and protection of copper busbars. It is soft and elastic, shrinking when heated (70°C-90°C), tightly wrapping the copper busbar to provide insulation and protection. It is typically made of polyolefin, but EVA is also available. This material shrinks when heated and possesses flame-retardant, insulating, and temperature-resistant properties. Its inner diameter rapidly shrinks upon heating, tightly encasing the protected copper busbar and preventing the effects of external environmental factors.

[0003] In practical applications, holes need to be drilled in these heat shrink tubings to facilitate necessary electrical connections. This process not only requires accurate hole placement but also demands high efficiency, especially in large-scale production environments.

[0004] Traditional hole-drilling methods primarily rely on manual operation or simple mechanical equipment. While manual operation is flexible, it is slow, lacks precision, and is particularly labor-intensive and inefficient when drilling multiple holes simultaneously. Existing mechanical equipment, although it can improve drilling precision and efficiency to some extent, often falls short when dealing with the need to drill multiple copper busbar heat shrink tubing holes simultaneously. Most existing equipment cannot process multiple workpieces at the same time, creating bottlenecks in the production process and increasing production time and costs.

[0005] Chinese patent application No. 202223110702.4 proposes a "copper busbar heat shrink tubing hole opener", which is equipped with a fixing plate and a drill bit. During use, the fixing plate and the drill bit work together to open multiple bolt holes on the copper busbar at the same time, thereby effectively improving the working efficiency of the device and reducing the labor intensity of the workers, thus reducing the input of labor costs.

[0006] However, in the above technical solution, multiple drill bits can only drill holes in one copper busbar heat shrink tubing, making batch drilling impossible, resulting in low efficiency and increased production time and costs. Utility Model Content

Detailed Implementation

[0033] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0034] Example 1

[0035] like Figure 1 As shown, an opening device for a copper busbar heat shrink tubing 10 according to this embodiment includes a support frame 1, a mounting frame 2, multiple opening components 3, and multiple positioning bases 4. It should be noted that, in terms of horizontal, vertical, and longitudinal directions, the length direction of the positioning base 4 can be defined as horizontal, the direction perpendicular to the length direction of the positioning base 4 in the same horizontal plane can be defined as longitudinal, and the height direction of the column 13 can be defined as vertical.

[0036] Specifically, such as Figure 1 and Figure 2As shown, the mounting frame 2 is vertically movable and mounted on the inner walls of the support frame 1. The mounting frame 2 has a transverse track 5 inside, with both ends of the transverse track 5 connected longitudinally to two longitudinal beams 21 of the mounting frame 2. Multiple opening components 3 are horizontally movable and mounted on the transverse track 5. Multiple positioning bases 4 are installed parallel and spaced on the bottom wall inside the support frame 1. Each positioning base 4 extends laterally and can accommodate one copper busbar heat shrink sleeve 10. Multiple opening components 3 can simultaneously open holes in one copper busbar heat shrink sleeve 10, and the transverse track 5 can drive multiple opening components 3 to move longitudinally along the length of the longitudinal beams 21 to open holes in other copper busbar heat shrink sleeves 10 within the positioning bases 4. By setting multiple positioning bases 4, multiple copper busbar heat shrink sleeves 10 can be accommodated and processed simultaneously. Each positioning base 4 is independently set, ensuring that the copper busbar heat shrink sleeves 10 do not interfere with each other during batch processing. The transverse track 5 is longitudinally movable, connected to two longitudinal beams 21 at both ends. This allows the opening assembly 3 to sequentially open holes in the copper busbar heat shrinkable sleeves 10 within different positioning bases 4, enabling batch processing of multiple copper busbar heat shrinkable sleeves 10 and significantly improving production efficiency. Because the opening assembly 3 can move laterally on the transverse track 5, each opening assembly 3 can precisely open holes at the same location on the same copper busbar heat shrinkable sleeve 10, ensuring accurate positioning and improving the quality of the opening.

[0037] Furthermore, such as Figure 1 and Figure 7 As shown, grooves 211 are provided on the opposite sidewalls of the two longitudinal beams 21, and moving devices 6 are installed in the two grooves 211. Slider 51 is provided at both ends of the transverse track 5. The transverse track 5 is embedded in the two grooves 211 through the sliders 51, and the two sliders 51 are respectively connected to the two moving devices 6. The two moving devices 6 can drive the transverse track 5 to move longitudinally through the two sliders 51, thereby driving the multiple opening components 3 to adjust their positions synchronously, realizing the sequential opening of multiple copper busbar heat shrink tubing 10, and improving the opening efficiency of multiple copper busbar heat shrink tubing 10.

[0038] Furthermore, such as Figure 7As shown, the moving device 6 includes a geared motor 61 and a threaded rod 62. An installation space 212 is provided inside the longitudinal beam 21. The geared motor 61 is fixedly installed in the installation space 212, and the threaded rod 62 is longitudinally installed in the slide groove 211. One end of the threaded rod 62 extends from the slide groove 211 into the installation space 212 and connects to the output end of the geared motor 61, while the other end is rotatably connected to the end wall of the slide groove 211. The slider 51 is screwed onto the threaded rod 62, forming a nut-screw structure. The geared motor 61 can drive the threaded rod 62 to rotate, thereby causing the slider 51 to move along the axial direction of the threaded rod 62 within the slide groove 211. This causes the transverse track 5 to move longitudinally along the length of the longitudinal beam 21, thus enabling the drilling of multiple copper busbar heat shrink tubing 10 and improving drilling efficiency.

[0039] Furthermore, such as Figure 6 As shown, the top of the positioning base 4 is provided with an arc-shaped positioning groove 41 to accommodate the copper busbar heat shrinkable sleeve 10. This groove positions the copper busbar heat shrinkable sleeve 10, ensuring it maintains the correct position initially. This not only improves the accuracy of the opening but also reduces quality problems caused by workpiece position deviations. Clamping devices 7 are respectively provided on both sides of the two transverse sidewalls of the positioning base 4. The two clamping devices 7 are arranged opposite each other and can move relative to each other simultaneously to clamp and fix the copper busbar heat shrinkable sleeve 10 placed in the arc-shaped positioning groove 41. This ensures the copper busbar heat shrinkable sleeve 10 remains stable throughout the opening process, avoiding errors caused by vibration or displacement, thereby guaranteeing the consistency and accuracy of the opening.

[0040] Furthermore, such as Figure 2 and Figure 6As shown, the clamping device 7 includes a clamping plate 71, a fixed base 72, and multiple cylinders 73. The fixed base 72 is mounted on the bottom inner wall of the support frame 1, and the multiple cylinders 73 are mounted parallel to each other at intervals on the top of the fixed base 72, with the output ends of the cylinders 73 facing the positioning base 4. The mounting side of the clamping plate 71 is connected to the protruding end of the cylinder 73, the clamping side of the clamping plate 71 faces the positioning base 4, and the bottom wall of the clamping plate 71 is in contact with the top wall of the positioning base 4. Through the coordinated work of the clamping plate 71, the fixed base 72, and the multiple cylinders 73, precise and stable clamping of the copper busbar heat shrink tubing 10 is achieved. The fixed base 72 is mounted on the bottom inner wall of the support frame 1, and the multiple cylinders 73 are mounted parallel to each other at intervals on its top, driving the clamping plate 71 through their output ends, enabling it to move quickly and smoothly to clamp or release the workpiece. The design of the bottom wall of the clamping plate 71 conforming to the top wall of the positioning base 4 ensures that the clamping side of the clamping plate 71 can disengage the copper busbar heat shrink sleeve 10 from the arc-shaped positioning groove 41, thereby improving the drilling accuracy and working efficiency. Preferably, the clamping side has an arc-shaped structure to adapt to the outer wall of the copper busbar heat shrink sleeve 10. It also allows the copper busbar heat shrink sleeve 10 to rise vertically when two clamping plates 71 clamp the same copper busbar heat shrink sleeve 10 at the same time, so that the copper busbar heat shrink sleeve 10 can disengage from the arc-shaped positioning groove 41. This ensures that the drilling assembly 3 will not touch the positioning groove when drilling the copper busbar heat shrink sleeve 10, thereby reducing the damage rate.

[0041] Furthermore, such as Figure 6 As shown, a buffer pad 74 is installed on the clamping side, which prevents the clamping plate 71 from damaging the outer wall of the copper busbar heat shrinkable sleeve 10 when clamping it, thus improving the quality of the opening. Furthermore, the side wall of the buffer pad 74 away from the clamping side is provided with anti-slip texture, which increases friction and prevents the copper busbar heat shrinkable sleeve 10 from detaching from the clamping plate 71 when clamped.

[0042] Furthermore, such as Figure 2As shown, the drilling assembly 3 includes a lateral movement mechanism 31, a drive motor 32, and a drill rod 33. The lateral movement mechanism 31 is movably mounted on the lateral movement track 5. The fixed end of the drive motor 32 is mounted on the bottom of the lateral movement mechanism 31, and the output end of the drive motor 32 is connected to the drill rod 33. The lateral movement mechanism 31 can drive the drive motor 32 and the drill rod 33 to move laterally along the lateral movement track 5, ensuring that the drill rod 33 can be quickly and accurately positioned to the location where drilling is required, thus improving the accuracy and efficiency of drilling. The drive motor 32 can drive the drill rod 33 to rotate around its own axis to drill holes in the copper busbar heat shrink tubing 10. By setting the drive motor 32, it can drive the drill rod 33 to rotate at high speed around its own axis, thereby achieving efficient drilling of the copper busbar heat shrink tubing 10. The outer wall of the drilling end of the drill rod 33 is provided with threads, which helps to discharge waste during the drilling process, prevents blockage, ensures the smooth progress of the drilling process, and further improves the drilling quality and efficiency.

[0043] Furthermore, such as Figure 3 and Figure 4 As shown, the traversing mechanism 31 includes a moving frame 311 and two sets of wheels 312. The traversing track 5 is an I-beam. The two sets of wheels 312 are rolledly connected to the traversing track 5, which reduces the friction of the traversing mechanism 31 when it moves on the traversing track 5, making the traversing mechanism 31 move more smoothly. The moving frame 311 includes two first horizontal sections 3111, two vertical sections 3112, and one second horizontal section 3113. The two first horizontal sections 3111 are flush and spaced apart. One end of the two first horizontal sections 3111 is connected to the top of the two vertical sections 3112 respectively, and the other end is placed in the traversing track 5. The top of the second horizontal section 3113 is connected to the bottom of the two vertical sections 3112 respectively. The two vertical sections 3112 are connected to the two sets of wheels 312 respectively through two connecting shafts 34. The fixed end of the drive motor 32 is connected to the bottom of the second horizontal section 3113, which makes the structure of the traversing mechanism 31 more stable. like Figure 4 and Figure 5 As shown, the top of the transverse track 5 has multiple elongated holes 52, and the two first horizontal sections 3111 each have multiple locking holes 31111 corresponding to the elongated holes 52. The moving frame 311 can be fixed to the transverse track 5 by inserting multiple pins 8 into the elongated holes 52 and the locking holes 31111. By providing multiple elongated holes 52 at the top of the transverse track 5 and multiple locking holes 31111 on the two first horizontal sections 3111, the position of the transverse mechanism 31 can be fixed by multiple pins 8, so that the moving frame 311 can be firmly fixed to the transverse track 5 when needed, avoiding safety hazards or accuracy errors caused by accidental movement.

[0044] Furthermore, such as Figure 2As shown, this embodiment also includes multiple lifting cylinders 9. The support frame 1 includes a top cover 11, a support base 12, and four columns 13. The two ends of the four columns 13 are respectively installed at the four corners of the top cover 11 and the support base 12. The fixed ends of the multiple lifting cylinders 9 are all installed at the bottom of the top cover 11, and the extended ends of the multiple lifting cylinders 9 are respectively connected to the top of the corresponding longitudinal beams 21 to drive the mounting frame 2 to move vertically. The longitudinal beams 21 are vertically movable to the two corresponding columns 13 through guide blocks 14 and guide grooves 15 to limit the direction of vertical movement of the longitudinal beams 21. By setting multiple lifting cylinders 9, it is possible to realize that when drilling is required, multiple lifting cylinders 9 can simultaneously drive the mounting frame 2 to descend vertically, while driving the motor 32 to drive the drill rod 33 to rotate, thereby realizing the drilling of the copper busbar heat shrink sleeve 10, improving the adaptability of the drilling device, and ensuring the stability and accuracy of the drilling process. After the drilling is completed, multiple lifting cylinders 9 can drive the mounting frame 2 to rise vertically, so that the drill rod 33 can drill the next copper busbar heat shrink sleeve 10. The two longitudinal beams 21 are vertically movable to the four columns 13 through guide blocks 14 and guide grooves 15, ensuring that the longitudinal beams 21 always maintain the correct orientation during vertical movement, effectively preventing the mounting frame 2 from shifting or shaking during movement, and further improving the accuracy and safety of the operation.

[0045] Based on the above structure, the working principle of the opening device for the copper busbar heat shrink tubing 10 in this embodiment is as follows:

[0046] like Figure 1 and Figure 2 As shown, the device is first assembled. After assembly, multiple copper busbar heat shrinkable sleeves 10 are placed in the arc-shaped positioning grooves 41 on the positioning base 4. Then, the output ends of two opposing cylinders 73 extend synchronously and drive the clamping sides of the two clamping plates 71 to move towards the positioning base 4. Since the clamping sides are arc-shaped, when the two clamping sides touch the copper busbar heat shrinkable sleeves 10, the copper busbar heat shrinkable sleeves 10 will enter the clamping side along with the arc-shaped structure of the clamping side, and the outer wall of the copper busbar heat shrinkable sleeves 10 will fit against the side wall of the clamping side facing the copper busbar heat shrinkable sleeves 10. At this time, the clamping of the copper busbar heat shrinkable sleeves 10 is completed.

[0047] Then, multiple opening components 3 are driven to open holes in the copper busbar heat shrink tubing 10. The following description focuses on one opening component 3; the operation of other opening components 3 is the same and will not be repeated here. Specifically, two wheel sets 312 are driven to move the moving frame 311, drive motor 32, and drill rod 33 laterally along the transverse track 5. The wheel sets 312 may have built-in motors to drive the wheels. When the axis of the drill rod 33 is coaxial with the axis of the position to be opened, the wheel sets 312 are stopped, and multiple pins 8 are passed through multiple elongated holes 52 at the top of the transverse track 5 and multiple locking holes 31111 on the two first horizontal sections 3111 corresponding to the elongated holes 52, fixing the moving frame 311 at the current position of the transverse track 5. Then, the drive motor 32 is driven to rotate the drill rod 33. The other multiple opening components 3 open holes in the copper busbar heat shrink tubing 10 according to the above operation, and will not be repeated here. Meanwhile, after all the opening components 3 have completed their preparations, multiple lifting cylinders 9 are driven simultaneously to drive the mounting frame 2 to descend vertically, thereby driving multiple opening components 3 to descend synchronously, so as to enable the drill rod 33 to open the copper busbar heat shrink sleeve 10.

[0048] After the current copper busbar heat shrink tubing 10 is drilled, multiple lifting cylinders 9 are simultaneously driven to rise, thereby causing the mounting frame 2 to rise vertically, so that the drill rod 33 is disengaged from the copper busbar heat shrink tubing 10. Then, the output end of the drive reduction motor 61 rotates, thereby driving the threaded rod 62 to rotate. Since the slider 51 is sleeved on the threaded rod 62 and forms a nut screw structure, the rotation of the threaded rod 62 causes the slider 51 to move along the axis of the threaded rod 62, which in turn causes the transverse track 5 to move longitudinally, thereby driving multiple drilling components 3 to move longitudinally to the position of the next copper busbar heat shrink tubing 10. To clarify, depending on actual needs, a corresponding sensor can be installed at the bottom of the transverse track 5 to detect the axial position of the next copper busbar heat shrinkable sleeve 10, thereby determining the position of the next copper busbar heat shrinkable sleeve 10 to be drilled. For example, the sensor can be a displacement sensor, electrically connected to the reduction motor 61. Since the distance between the axes of each positioning base 4 is fixed, the displacement sensor can transmit an electrical signal to the reduction motor 61 to drive the reduction motor 61 to start and stop, thus determining the position of the next copper busbar heat shrinkable sleeve 10 to be drilled. Alternatively, a line-following sensor can be used, electrically connected to the reduction motor 61. A black or white line is drawn at the axial position of the positioning base 4. The line-following sensor transmits an electrical signal to the reduction motor 61 by detecting the black or white line, thus driving the reduction motor 61 to start and stop, thereby determining the position of the next copper busbar heat shrinkable sleeve 10 to be drilled. Other sensors that can achieve this function can also be used, but will not be elaborated here. Continue to drill the next copper busbar heat shrinkable sleeve 10 according to the above drilling operation, which will not be elaborated here.

[0049] After all the copper busbar heat shrink tubing 10 on the multiple positioning bases 4 have been drilled, remove the drilled copper busbar heat shrink tubing 10, replace it with another copper busbar heat shrink tubing 10 that needs to be drilled, and continue to perform the above operation. It will not be described in detail here.

[0050] This embodiment enables the opening component 3 to sequentially open the copper busbar heat shrink tubing 10 in different positioning bases 4 by setting a longitudinally movable transverse track 5 and multiple positioning bases 4, thereby realizing batch processing of multiple copper busbar heat shrink tubing 10, improving work efficiency, and saving production time and production costs.

[0051] Example 2

[0052] Unlike Embodiment 1, this embodiment provides an opening device for a copper busbar heat shrink tubing 10, which includes a protective cover (not shown in the figure). A mounting groove is provided around the top perimeter of the support base 12, and the protective cover can be placed inside the mounting groove to cover the entire opening device. This prevents waste debris from flying out and injuring operators when the opening assembly 3 is opening the copper busbar heat shrink tubing 10.
