Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0027] The following is combined with Figures 1 to 4 This application describes the sleeve conveying device and the busbar welding machine.

[0028] According to the embodiments of the first aspect of this application, such as Figure 2 and Figure 3 As shown, the cannula delivery device includes a cannula delivery conduit 26, a cannula delivery assembly 21, and a cannula shearing assembly 22. The cannula delivery conduit 26 forms a cannula delivery cavity. The cannula delivery assembly 21 is disposed on one side of the cannula delivery conduit 26. The cannula delivery cavity is used to guide the cannula to move to the cannula delivery assembly 21. The cannula delivery assembly 21 is used to drive the cannula to move. The cannula delivery assembly 21 is located between the cannula shearing assembly 22 and the cannula delivery conduit 26. The cannula delivery assembly 21 is used to drive the cannula to move to the cannula shearing assembly 22. The cannula shearing assembly 22 is used to shear the cannula.

[0029] According to the cannula delivery device of this application embodiment, the cannula delivery cavity of the cannula delivery conduit 26 is used for cannula insertion to guide the cannula, allowing it to move precisely to the cannula delivery assembly 21. The cannula delivery assembly 21 then moves the cannula to the cannula cutting assembly 22, which cuts the cannula to obtain a cannula segment of the target length. In other words, this application uses the cannula delivery conduit 26 to guide the cannula, ensuring precise delivery to the cannula delivery assembly 21. The cannula delivery assembly 21 enables automatic cannula delivery, and the cannula cutting assembly 22 enables automatic cannula cutting. Through the cooperation of the cannula delivery assembly 21 and the cannula cutting assembly 22, the cannula can be precisely cut to obtain a cannula segment of the target length, ensuring that the length of the cannula segments for different wire harnesses is the same, thereby effectively improving the automation level of cannula processing.

[0030] In some embodiments, such as Figure 2 and Figure 3As shown, the cannula delivery conduit 26 has a notch 261 that communicates with the cannula delivery cavity.

[0031] Understandably, since notch 261 is connected to the sleeve delivery cavity, the sleeve will be exposed at notch 261 to facilitate laser marking of the sleeve.

[0032] In some embodiments, such as Figure 2 and Figure 3 As shown, the sleeve conveying assembly 21 includes at least two sleeve feeding wheels 211, which are arranged opposite to each other.

[0033] Understandably, the two oppositely positioned sleeve feed rollers 211 clamp the sleeve in the middle, and when the two sleeve feed rollers 211 rotate, they will drive the sleeve to move, so as to realize the automatic feeding of the sleeve.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, the sleeve shearing assembly 22 includes a shearing drive 221, a first shearing blade 222, and a second shearing blade 223. The first shearing blade 222 and the second shearing blade 223 are both connected to the shearing drive 221. The shearing drive 221 is used to drive the first shearing blade 222 and the second shearing blade 223 to move closer to or further away from each other.

[0035] Understandably, when it is necessary to cut the sleeve, the shearing drive 221 moves the first shearing blade 222 and the second shearing blade 223 closer together to cut the sleeve. When it is not necessary to cut the sleeve, the shearing drive 221 moves the first shearing blade 222 and the second shearing blade 223 further apart so that the sleeve can move between the first shearing blade 222 and the second shearing blade 223.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the casing conveying device further includes a casing guide 27, which is disposed between the casing shearing assembly 22 and the casing conveying assembly 21. The casing guide 27 forms a casing guide cavity, which is used to guide the casing from the casing conveying assembly 21 to the casing shearing assembly 22.

[0037] Understandably, the casing guide cavity of the casing guide 27 allows the casing to pass through, enabling the casing guide 27 to guide the casing. Since the casing guide 27 is located between the casing shearing assembly 22 and the casing conveying assembly 21, the casing conveying assembly 21 conveys the casing to the casing guide 27, and the casing guide 27 can guide the casing to move to the casing shearing assembly 22, allowing the casing to move accurately from the casing conveying assembly 21 to the casing shearing assembly 22.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the cannula delivery device also includes a cannula missing detection component 28. The cannula missing detection component 28 is located on the side of the cannula delivery conduit 26 away from the cannula delivery component 21. The cannula missing detection component 28 is used to detect whether there is a cannula at the cannula delivery conduit 26.

[0039] Understandably, the missing tube detection component 28 can detect whether there is a sleeve at the sleeve delivery conduit 26, thereby promptly identifying the missing sleeve so that staff can handle it in time and avoid the situation where the wire harness is not sleeved.

[0040] Specifically, such as Figure 2 and Figure 3 As shown, the tube shortage detection assembly 28 includes a tube shortage detection plate 281 and a tube shortage detection element 282. The tube shortage detection plate 281 has a sleeve hole 2811, which is disposed opposite to the sleeve delivery cavity. The tube shortage detection element 282 is connected to the tube shortage detection plate 281 and is used to detect whether there is a sleeve between the sleeve hole 2811 and the sleeve delivery cavity.

[0041] It is understandable that both the casing hole 2811 and the casing delivery cavity are used for casing insertion. This means that under normal circumstances, the casing will be inserted from the casing hole 2811 into the casing delivery cavity. Therefore, the casing can be detected between the casing hole 2811 and the casing delivery cavity. Thus, the casing missing detection device 282 can be used to detect whether there is a casing missing between the casing hole 2811 and the casing delivery cavity, thereby determining whether a casing is missing. In other words, the casing missing detection device 282 can achieve automatic detection of missing casing.

[0042] For example, the tube shortage detection element 282 includes a pressure detection element, and the tube shortage detection assembly 28 further includes a detection frame 283, which is rotatably connected to the tube shortage detection plate 281. The detection frame 283 abuts against the pressure detection element, wherein...

[0043] When there is a sleeve between the sleeve hole 2811 and the sleeve delivery cavity, the side of the detection frame 283 away from the pressure detection element abuts against the sleeve to support the sleeve.

[0044] Understandably, when the sleeve is sequentially inserted into the sleeve hole 2811 and the sleeve delivery cavity, meaning there is a sleeve between the sleeve hole 2811 and the sleeve delivery cavity, the side of the detection frame 283 facing away from the pressure detection element will abut against the sleeve, providing support for the sleeve. In other words, part of the sleeve's weight will act on the detection frame 283, and the pressure detection data can then be used to determine whether there is a sleeve between the sleeve hole 2811 and the sleeve delivery cavity, thus achieving automatic detection of missing sleeves.

[0045] It is understandable that the pressure detection value of the pressure sensor when there is a sleeve between the sleeve hole 2811 and the sleeve delivery cavity will be greater than the pressure detection value when there is no sleeve between the sleeve hole 2811 and the sleeve delivery cavity.

[0046] Specifically, the tube missing detection device 282 includes a tube missing imaging device, which is disposed between the sleeve hole 2811 and the sleeve delivery cavity. The tube missing imaging device is used to detect whether there is a sleeve between the sleeve hole 2811 and the sleeve delivery cavity.

[0047] Understandably, the missing tube imaging device can be used to take pictures of the area between the sleeve hole 2811 and the sleeve delivery cavity. Based on the captured images, it can be determined whether there is a sleeve between the sleeve hole 2811 and the sleeve delivery cavity, so as to achieve automatic detection of missing sleeves.

[0048] According to an embodiment of the second aspect of this application, the busbar welding machine includes the aforementioned sleeve conveying device.

[0049] According to the busbar welding machine of this application embodiment, the sleeve delivery chamber of the sleeve delivery conduit 26 is used for sleeve insertion to guide the sleeve, allowing it to move precisely to the sleeve delivery assembly 21. The sleeve delivery assembly 21 then moves the sleeve to the sleeve shearing assembly 22, which shears the sleeve to obtain a sleeve segment of the target length. In other words, this application uses the sleeve delivery conduit 26 to guide the sleeve, ensuring precise delivery to the sleeve delivery assembly 21. The sleeve delivery assembly 21 enables automatic sleeve delivery, and the sleeve shearing assembly 22 enables automatic sleeve cutting. Through the cooperation of the sleeve delivery assembly 21 and the sleeve shearing assembly 22, the sleeve can be precisely cut to obtain a sleeve segment of the target length, ensuring that the sleeve segments for different wire harnesses are of the same length, thereby effectively improving the automation level of sleeve processing.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the busbar welding machine also includes a sleeve clamping assembly 23 and a sleeve moving assembly 24. A sleeve cutting assembly 22 is located on one side of the sleeve conveying assembly 21. The sleeve conveying assembly 21 is used to move the sleeve to the sleeve cutting assembly 22. The sleeve cutting assembly 22 is used to cut the sleeve to obtain a sleeve segment of the target length. The sleeve clamping assembly 23 is located on the side of the sleeve cutting assembly 22 away from the sleeve conveying assembly 21. The sleeve clamping assembly is used to clamp the sleeve segment. The sleeve moving assembly 24 is connected to the sleeve clamping assembly 23. The sleeve moving assembly 24 is used to move the sleeve clamping assembly 23 so that the sleeve segment is fitted onto the wire harness.

[0051] According to the busbar welding machine of this application embodiment, the sleeve conveying assembly 21 can realize automatic sleeve conveying, and the sleeve cutting assembly 22 can realize automatic sleeve cutting. Through the cooperation of the sleeve conveying assembly 21 and the sleeve cutting assembly 22, the sleeve can be precisely cut to obtain a sleeve segment of the target length. When the sleeve cutting assembly 22 cuts the sleeve, the sleeve clamping assembly 23 clamps the sleeve to prevent the sleeve segment from falling off. Then, the sleeve moving assembly 24 drives the sleeve clamping assembly 23 to move, so that the sleeve segment moves together to the wire harness. Then, the sleeve moving assembly 24 continues to drive the sleeve clamping assembly 23 to move towards the wire harness, or drives the wire harness to move towards the sleeve segment, so that the sleeve segment is sleeved on the wire harness, thereby automatically completing the sleeve operation of the wire harness and improving the degree of automation.

[0052] In some embodiments, such as Figure 2 and Figure 4 As shown, the sleeve clamping assembly 23 includes a sleeve clamping drive 231, a first clamping member 232, and a second clamping member 233. The first clamping member 232 and the second clamping member 233 are both connected to the sleeve clamping drive 231. The sleeve clamping drive 231 is used to drive the first clamping member 232 and the second clamping member 233 to move closer or further apart from each other in order to clamp or release the sleeve segment.

[0053] Understandably, when the sleeve clamping drive 231 moves the first clamping member 232 and the second clamping member 233 closer together, the sleeve segment can be clamped by the first clamping member 232 and the second clamping member 233. When the sleeve clamping drive 231 moves the first clamping member 232 and the second clamping member 233 away from each other, the first clamping member 232 and the second clamping member 233 can release the sleeve segment. In other words, before the sleeve segment is fitted onto the wire harness, the sleeve clamping drive 231 can move the first clamping member 232 and the second clamping member 233 closer together to prevent the sleeve segment from falling off. After the sleeve segment is fitted onto the wire harness, the sleeve clamping drive 231 can move the first clamping member 232 and the second clamping member 233 away from each other, so that the first clamping member 232 and the second clamping member 233 no longer clamp the sleeve segment, thus preventing the first clamping member 232 and the second clamping member 233 from pulling the sleeve segment out of the wire harness.

[0054] Specifically, such as Figure 2 and Figure 4 As shown, a sleeve guide slope 234 is formed on the side of the first clamping member 232 and / or the second clamping member 233 opposite to the sleeve shearing assembly 22. The sleeve guide slope 234 is used to guide the sleeve segment to be sleeved on the wire harness.

[0055] It is understood that the side of the first clamping member 232 facing away from the sleeve shearing assembly 22 and the side of the second clamping member 233 facing away from the sleeve shearing assembly are oriented towards the wire harness. A sleeve guide slope 234 is formed on the side of the first clamping member 232 facing away from the sleeve shearing assembly 22 and / or the side of the second clamping member 233 facing away from the sleeve shearing assembly 22. The sleeve guide slope 234 is oriented towards the wire harness, so the sleeve guide slope 234 can guide the wire harness, allowing the wire harness to be smoothly inserted into the sleeve segment held by the first clamping member 232 and the second clamping member 233 along the sleeve guide slope 234, realizing the operation of sleeve segment being fitted onto the wire harness.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the sleeve moving assembly 24 includes a sleeve moving drive 241, which is connected to the sleeve clamping assembly 23. The sleeve moving drive 241 is used to drive the sleeve clamping assembly 23 to move relative to the sleeve shearing assembly 22.

[0057] Understandably, after the sleeve cutting assembly 22 completes the cutting of the sleeve and the sleeve clamping assembly 23 clamps the sleeve segment, the sleeve moving drive 241 drives the sleeve clamping assembly 23 to move away from the sleeve cutting assembly 22, so that the sleeve segment moves towards the wire harness and is fitted onto the wire harness. After the wire harness is fitted, the sleeve moving drive 241 drives the sleeve clamping assembly 23 to move towards the sleeve cutting assembly 22, so that the sleeve clamping assembly 23 can then clamp the next sleeve segment. That is, this embodiment can realize the automatic movement of the sleeve segment between the sleeve cutting assembly 22 and the wire harness, improving the degree of automation.

[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, the sleeve moving assembly 24 further includes a sleeve connecting plate 242. The first end of the sleeve connecting plate 242 is connected to the sleeve clamping assembly 23, and the second end of the sleeve connecting plate 242 is connected to the sleeve moving drive 241. The sleeve moving drive 241 is arranged side by side with the sleeve conveying assembly 21.

[0059] It is understandable that the sleeve moving drive component 241 and the sleeve clamping assembly 23 are connected together by the sleeve connecting plate 242, so that the sleeve moving drive component 241 can drive the sleeve clamping assembly 23 to move through the sleeve connecting plate 242. At the same time, since the sleeve moving drive component 241 and the sleeve clamping assembly 23 are not directly connected, but connected through the sleeve connecting plate 242, the sleeve moving drive component 241 can be set to be arranged side by side with the sleeve conveying assembly 21, making the overall structure of the busbar welding machine more compact.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, the busbar welding machine also includes a marking component 25, which is located above the sleeve conveying component 21 and is used to mark the sleeve.

[0061] Understandably, marking the sleeves with the marking component 25 enables automated marking of the sleeves, thereby improving the automation level of the entire busbar welding machine.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the marking assembly 25 includes a marking mounting base 251 and a laser marking machine 252. The laser marking machine 252 is mounted on the marking mounting base 251 and is located above the sleeve conveying assembly 21. The laser marking machine 252 is used to mark the sleeve.

[0063] Understandably, the marking mounting base 251 can support the laser marking machine 252, allowing the laser marking machine 252 to be stably positioned above the sleeve conveying assembly 21, thereby enabling the laser marking machine 252 to automatically mark the sleeve at the sleeve output assembly.

[0064] Specifically, the marking assembly 25 also includes a marking drive component, which is mounted on the marking mounting base 251. The laser marking machine 252 is connected to the marking drive component, and the marking drive component is used to drive the laser marking machine 252 to move.

[0065] It is understandable that the laser marking machine 252 can be moved relative to the sleeve by the marking drive component, thereby adjusting the distance or angle between the laser marking machine 252 and the sleeve to ensure the marking effect of the laser marking machine 252.

[0066] In some embodiments, such as Figure 2 and Figure 3 As shown, the busbar welding machine also includes a sleeve delivery conduit 26, which is located on the side of the sleeve delivery assembly 21 away from the sleeve shearing assembly 22. The sleeve delivery conduit 26 forms a sleeve delivery cavity, which is used to guide the sleeve to move to the sleeve delivery assembly 21.

[0067] Understandably, the casing delivery chamber of the casing delivery conduit 26 is used for casing insertion to guide the casing, allowing it to be accurately moved to the casing delivery assembly 21. In other words, the casing can be guided through the casing delivery conduit 26, enabling it to be accurately delivered to the casing delivery assembly 21.

[0068] It should be noted that in this application, the driving component may be, for example, a motor, a cylinder, or any other suitable driving structure. Furthermore, since the driving component is an existing part, its specific structure and working principle will not be described in detail here.

[0069] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
