Description

Technical Field

[0001] This invention relates to the technical field of cutting equipment, and more specifically, to a copper busbar heat shrink tubing cutting device and its working method. Background Technology

[0002] Copper busbar heat shrink tubing is a heat shrinkable material used for the insulation and protection of copper busbars. During use, it needs to be cut to a fixed length according to the actual length of the copper busbar. Currently, copper busbar heat shrink tubing is mostly cut using simple tubing cutters. These simple cutters typically use top-to-bottom cutting or rotary cutting methods. Because the surface of the heat shrink tubing is smooth and tubular, it is very easy for it to roll circumferentially or move axially under cutting force, resulting in dimensional deviations and uneven cuts.

[0003] Some equipment uses a unidirectional or bidirectional cutting method, which cannot complete the circumferential cutting of the pipe in one go. It often requires multiple cuts or manual rotation of the pipe, which is cumbersome and inefficient. Although there are existing technologies that fix the pipe and cut it, they have problems such as unstable fixation, easy damage to the pipe, and low cutting accuracy and efficiency. Summary of the Invention

[0004] The present invention aims to solve the problems of existing equipment causing copper busbar heat shrink tubing to shift position during cutting, making it difficult to complete the circumferential cutting in one go, and resulting in low cutting accuracy and uneven cuts.

[0005] To address the aforementioned problems, this invention provides a copper busbar heat shrink tubing cutting device, comprising a base, a support seat fixed on the base, a through hole on the support seat, and an upper side blade, a left side blade, a lower side blade, and a right side blade arranged sequentially around one side of the support seat and around the through hole. An upper cylinder is fixed on the support seat, and a fixing plate is fixedly connected to the output end of the upper cylinder. The upper side blade is fixed to the bottom of the fixing plate, and a spring is fixedly connected to the bottom of the fixing plate. A pressure block is fixedly connected to the other end of the spring. A notch is provided on the top edge of the support seat, and the bottom of the pressure block extends through the notch into the through hole. An air pump is fixedly connected to one side of the support seat, and several suction holes are provided inside the support seat. The output end of the air pump is connected to one end of the suction hole, and the other end of the suction hole is connected to the through hole. A transfer assembly for transferring the copper busbar heat shrink tubing into the through hole is also provided on the base.

[0006] The copper busbar heat shrink tubing cutting device provided by this invention has, but is not limited to, the following beneficial effects compared with the prior art: The copper heat shrink tubing is adsorbed by an air pump and suction port, allowing the tubing to adhere to the inner wall of the through hole for positioning and preventing it from rolling. Then, a pressure block is used to press the tubing firmly before cutting for secondary fixation, which can effectively prevent the tubing from rolling circumferentially or moving axially during the cutting process, thus improving cutting accuracy. The upper side blade and the lower side blade, as well as the right side blade and the left side blade, can simultaneously complete the circumferential cutting of the tubing, cutting the tubing in one go without the need for multiple cuts, simplifying the operation process, effectively improving cutting efficiency, and ensuring a neat and flat cut.

[0007] Furthermore, the transfer assembly includes a base plate fixed to the base, on which a movable plate for supporting the copper busbar heat shrink tubing is slidably connected.

[0008] Furthermore, a right cylinder is fixed to one side of the support base, and the output end of the right cylinder is fixedly connected to the right side blade. The left side blade and the lower side blade are both fixedly connected to the support base.

[0009] Furthermore, the cutting edges of the upper side blade, left side blade, lower side blade, and right side blade are all positioned facing the through hole.

[0010] Furthermore, the bottom height of the pressure block is lower than the bottom height of the upper side blade.

[0011] Furthermore, the outer wall of the pressure block fits into the inner wall of the notch on the support base.

[0012] Furthermore, several air intake holes are evenly arranged along the extension direction of the through hole.

[0013] Furthermore, the upper and lower blades are located in the same vertical plane, and the left and right blades are located in the same vertical plane.

[0014] Furthermore, the height of the air intake hole is consistent with the height of the upper surface of the movable plate.

[0015] The present invention also provides a method for operating a copper busbar heat shrink tubing cutting device, the method comprising the following steps: S1: Place the copper busbar heat shrink tubing to be cut on the moving plate, and push the copper busbar heat shrink tubing into the through hole of the support base by sliding the moving plate along the base plate, so that the section to be cut at one end of the copper busbar heat shrink tubing extends out of the through hole. S2: Start the upper cylinder to drive the pressure block down, maintaining the gap between the pressure block and the copper busbar heat shrink tubing.

[0016] S3: Start the air pump. The air pump uses the suction hole to adsorb and fix the copper busbar heat shrink tubing in the through hole, so that the copper busbar heat shrink tubing is attached to the inner wall of the through hole. S4: Restart the upper cylinder. The output end of the upper cylinder extends downward, causing the fixing plate to move down. The pressure block at the bottom of the fixing plate first contacts the surface of the copper busbar heat shrink tubing. As the upper cylinder continues to extend, the spring is compressed, and the pressure block presses firmly onto the surface of the copper busbar heat shrink tubing to complete the fixing. Then, the upper side blade at the bottom of the fixing plate moves down and cooperates with the lower side blade to complete the cutting. S4: Simultaneously with S4, the right cylinder is started. The output end of the right cylinder extends and drives the right blade to move towards the through hole, cooperating with the left blade to perform a circular cut on the copper busbar heat shrink tubing.

[0024] See Figure 1An embodiment of the present invention provides a copper busbar heat shrink tubing cutting device, comprising a base 1, a support seat 2 fixed on the base 1, a through hole 3 on the support seat 2, and an upper blade 7, a left blade 10, a lower blade 9, and a right blade 5 arranged sequentially around one side of the support seat 2 and around the through hole 3. An upper cylinder 6 is fixed on the support seat 2, and a fixing plate 12 is fixedly connected to the output end of the upper cylinder 6. The upper blade 7 is fixed to the bottom of the fixing plate 12, and a spring is also fixedly connected to the bottom of the fixing plate 12. 13. The other end of the spring 13 is fixedly connected to a pressure block 14. The top edge of the support base 2 is provided with a notch. The bottom of the pressure block 14 extends through the notch into the through hole 3. An air pump 8 is fixedly connected to one side of the support base 2. Several air suction holes 17 are provided in the support base 2. The output end of the air pump 8 is connected to one end of the air suction hole 17. The other end of the air suction hole 17 is connected to the through hole 3. The base 1 is also provided with a transfer assembly 11 for transferring the copper busbar heat shrink tubing into the through hole 3.

[0025] In this embodiment, the copper busbar heat shrink tubing is initially adhered and fixed to the inner wall of the through hole 3 by suction through the air hole 17, effectively preventing the tubing from rolling circumferentially within the through hole 3. Then, driven by the upper cylinder 6, the pressure block 14 contacts the copper busbar heat shrink tubing before the upper side blade 7, which can complete the pressing and fixing of the copper busbar heat shrink tubing before the cutting action begins, further preventing the copper busbar heat shrink tubing from moving axially. The double fixing can ensure the fixing stability without excessively damaging the tubing. With the four blades on the upper, lower, left and right sides cutting simultaneously to complete the circumferential cutting, the copper busbar heat shrink tubing can be cut off in one go, resulting in a neat and flat cut, effectively improving the cutting accuracy and cutting efficiency, and avoiding problems such as dimensional deviation, uneven cuts, and cumbersome operation.

[0026] Optionally, the transfer assembly 11 includes a base plate 15 fixed on the base 1, and a movable plate 16 for supporting the copper busbar heat shrink tubing is slidably connected to the base plate 15.

[0027] In this embodiment, the movement of the movable plate 16 can be controlled by manual pushing or electric push rod to control the length of the copper busbar heat shrink tubing extending out of the through hole 3.

[0028] Optionally, a right cylinder 4 is fixed to one side of the support base 2, and the output end of the right cylinder 4 is fixedly connected to the right side blade 5. The left side blade 10 and the lower side blade 9 are both fixedly connected to the support base 2.

[0029] In this embodiment, the upper side blade 7 is driven by the upper cylinder 6 and the right side blade 5 is driven by the right cylinder 4. The circumferential cutting can be completed in conjunction with the fixed lower side blade 9 and left side blade 10.

[0030] Optionally, the cutting edges of the upper blade 7, left blade 10, lower blade 9, and right blade 5 are all positioned facing the through hole 3.

[0031] In this embodiment, the four blades face the center of the through hole 3, and can apply cutting force to the copper busbar heat shrink tubing simultaneously during cutting. A complete annular cut can be completed in one pass, without the need to adjust the position of the tubing or make multiple passes.

[0032] Optionally, the bottom height of the pressure block 14 is lower than the bottom height of the upper side blade 7.

[0033] In this embodiment, the bottom height of the pressure block 14 is relatively high so as to ensure that during the downward extension of the upper cylinder 6, the pressure block 14 first contacts and presses the copper busbar heat shrink tubing, and then the upper side blade 7 contacts the tubing to complete the cutting. This ensures that the cutting is carried out after the fixing is completed, and avoids the copper busbar heat shrink tubing from shifting during the cutting process.

[0034] Optionally, the outer wall of the pressure block 14 is fitted to the inner wall of the notch on the support base 2.

[0035] In this embodiment, the outer wall of the pressure block 14 is in close contact with the inner wall of the notch on the support base 2, which can improve the adsorption force of the air intake hole 17 and prevent air leakage from the gap between the pressure block 14 and the notch during the air intake process.

[0036] Optionally, a plurality of air intake holes 17 are evenly arranged along the extension direction of the through hole 3.

[0037] In this embodiment, the uniformly arranged suction holes 17 can form a uniform adsorption force on the wall of the copper busbar heat shrink tubing, so that the copper busbar heat shrink tubing is uniformly attached to the inner wall of the through hole 3, resulting in a better positioning effect.

[0038] Optionally, the upper blade 7 and the lower blade 9 are located in the same vertical plane, and the left blade 10 and the right blade 5 are located in the same vertical plane.

[0039] In this embodiment, when the upper blade 7 feeds downward, its blade can precisely align with the blade of the lower blade 9. When the right blade 5 feeds horizontally, its blade can also precisely align with the blade of the left blade 10, ensuring uniform force during cutting and complete alignment of the cut, without any rough edges or incomplete cuts.

[0040] Optionally, the height of the air intake 17 is the same as the height of the upper surface of the movable plate 16.

[0041] In this embodiment, the suction hole 17 can be used to adsorb the middle part of the copper heat shrink tubing that is placed on the moving plate 16 and fed into the through hole 3, resulting in the best adsorption and positioning effect.

[0042] Another embodiment of the present invention provides a method for operating a copper busbar heat shrink tubing cutting device, the method specifically including the following steps: S1: Place the copper busbar heat shrink tubing to be cut on the moving plate 16, and push the copper busbar heat shrink tubing into the through hole 3 of the support base 2 by sliding the moving plate 16 along the base plate 15, so that the section to be cut at one end of the copper busbar heat shrink tubing extends out of the through hole 3. S2: Start the upper cylinder 6 to drive the pressure block 14 down, maintaining the gap between the pressure block 14 and the copper busbar heat shrink tubing.

[0043] S3: Start the air pump 8. The air pump 8 uses the suction hole 17 to adsorb and fix the copper heat shrink tubing in the through hole 3, so that the copper heat shrink tubing is attached to the inner wall of the through hole 3. S4: Start the upper cylinder 6 again. The output end of the upper cylinder 6 extends downward, driving the fixing plate 12 to move down. The pressure block 14 at the bottom of the fixing plate 12 first contacts the surface of the copper busbar heat shrink tubing. As the upper cylinder 6 continues to extend, the spring 13 is compressed, and the pressure block 14 presses firmly on the surface of the copper busbar heat shrink tubing to complete the fixation. Then the upper side blade 7 at the bottom of the fixing plate 12 moves down and cooperates with the lower side blade 9 to complete the cutting. S5: Performed synchronously with S4, the right cylinder 4 is started. The output end of the right cylinder 4 extends and drives the right blade 5 to move towards the through hole 3, cooperating with the left blade 10 to perform a circular cut on the copper busbar heat shrink tubing.

[0044] After the cutting is completed, each cylinder resets, and the transfer component 11 moves the cut copper busbar heat shrink tubing out, while simultaneously feeding in the next section of copper busbar heat shrink tubing to be cut. The above operation can be repeated.

[0045] It should be noted that the purpose of starting the upper cylinder 6 before starting the air pump 8 and driving the pressure block 14 to press down is to compress the space between the pressure block 14 and the bottom of the through hole 3, improve the adsorption force of the suction hole 17 on the copper busbar heat shrink tubing, ensure the stability of the adsorption positioning, and avoid the copper busbar heat shrink tubing not being able to fit properly when the air pump 8 is sucking air, which would affect the subsequent cutting accuracy.

[0046] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
