Technical Field

[0001] This application relates to the field of battery component processing technology, specifically to terminal crimping devices and busbar welding machines. Background Technology

[0002] In the field of lithium-ion battery module manufacturing, the CCS (Cell Contacting System) is a core component, undertaking key functions such as electrical connection of individual battery cells, temperature and voltage signal acquisition, and module-level current transmission. Its structure typically consists of an insulating support, busbars (aluminum or copper), and acquisition harnesses (FPC or FFC cables). Among these, the reliable connection between the harnesses and the busbars is crucial for ensuring the electrical performance and safety of the battery module, directly affecting the battery system's energy efficiency, signal transmission stability, and long-term cycle life.

[0003] Before connecting the wire harness and busbar, pre-treatment operations such as stripping, sleeve application, and crimping terminals are required. After crimping the terminals, the effectiveness of the crimping must be checked. Currently, related technologies primarily rely on manual inspection of the crimped terminals, and the level of automation needs improvement. Utility Model Content

[0004] Embodiments of this application provide a terminal crimping device and a busbar welding machine.

[0010] In one embodiment, the terminal crimping detection assembly includes a terminal crimping camera and a terminal crimping camera holder. The terminal crimping camera and the terminal crimping camera holder are disposed opposite to each other. A background surface is formed on the side of the terminal crimping camera holder facing the terminal crimping camera, and a space for accommodating a wire harness is formed between the background surface and the terminal crimping camera.

[0011] In one embodiment, the crimping terminal imaging device includes a crimping terminal mounting base, a crimping terminal camera, and a crimping terminal cover. Both the crimping terminal camera and the crimping terminal cover are connected to the crimping terminal mounting base. The crimping terminal cover is disposed above the crimping terminal imaging base, and the crimping terminal cover forms a crimping terminal detection channel. The crimping terminal camera can detect the effect of crimping the wire harness terminals through the crimping terminal detection channel.

[0012] In one embodiment, the crimp terminal detection assembly further includes an illumination element, the crimp terminal cover forms a crimp terminal cavity communicating with the crimp terminal detection channel, and the illumination element is disposed in the crimp terminal cavity and spaced apart from the crimp terminal detection channel.

[0018] The beneficial effects of the embodiments of this application are as follows:

[0019] In the embodiments of this application, a crimping assembly can be used to crimp terminals onto the wire harness. After the crimping operation is completed, the wire harness is moved to a crimping detection assembly, which detects the effectiveness of the crimping to determine if it meets the requirements. If the crimping is successful, the wire harness with crimped terminals is moved to a heat-shrink assembly for heat-shrinking, improving the connection stability between the terminals and the wire harness. In other words, this application automates the crimping process, automatically detects the crimping effect, and automatically heat-shrinks the crimped wire harness, effectively improving the automation level of the crimping device.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] The following is combined with Figures 1 to 4 This application describes the crimping terminal device and busbar welding machine.

[0027] According to the embodiments of the first aspect of this application, such as Figure 3 and Figure 4As shown, the crimping device includes a crimping assembly 31, a crimping detection assembly 32, and a heat shrinking assembly 33. The crimping assembly 31 is used to crimp terminals onto the wire harness. The crimping detection assembly 32 is located on one side of the crimping assembly 31 and is used to detect the effect of crimping terminals onto the wire harness. The heat shrinking assembly 33 is located on one side of the crimping assembly 31 and is used to heat shrink the wire harness with crimped terminals.

[0028] According to the terminal crimping device of this application embodiment, the terminal crimping assembly 31 can perform terminal crimping operations on the wire harness. After the terminal crimping operation of the wire harness is completed, the wire harness is moved to the terminal crimping detection assembly 32, which detects the effect of the wire harness terminal crimping to determine whether the effect of the wire harness terminal crimping meets the requirements. If the effect of the wire harness terminal crimping meets the requirements, the wire harness with crimped terminals is moved to the heat shrink assembly 33, which heat shrinks the wire harness to improve the connection stability between the terminals and the wire harness. In other words, this application realizes automated processing of wire harness terminal crimping, automated detection of the effect of wire harness terminal crimping, and automated heat shrinking of wire harnesses with crimped terminals, effectively improving the automation level of the terminal crimping device.

[0029] In some embodiments, the crimp terminal detection component 32 is located between the crimp terminal component 31 and the heat shrink component 33.

[0030] It is understandable that the crimping terminal detection component 32 is set between the crimping terminal component 31 and the heat shrink component 33, that is, the crimping terminal component 31, the crimping terminal detection component 32 and the heat shrink component 33 are arranged in sequence. After the wire harness completes the crimping terminal operation at the crimping terminal component 31, the wire harness can be moved to the crimping terminal detection component 32 for crimping terminal effect detection. Then the wire harness can be moved to the heat shrink component 33 for heat shrinking. There is no need to move the wire harness back and forth, which improves efficiency.

[0031] In some embodiments, such as Figure 3 and Figure 4 As shown, the terminal crimping detection assembly 32 includes a terminal crimping camera 321 and a terminal crimping camera holder 322. The terminal crimping camera 321 and the terminal crimping camera holder 322 are disposed opposite to each other. A background surface 3221 is formed on the side of the terminal crimping camera holder 322 facing the terminal crimping camera 321. A space for accommodating the wire harness is formed between the background surface 3221 and the terminal crimping camera 321.

[0032] It is understandable that after the crimping operation of the wire harness is completed, the wire harness is moved between the background surface 3221 and the crimping terminal camera 321. Since the crimping terminal camera 321 and the crimping terminal camera holder 322 are arranged opposite to each other, that is, the crimping terminal camera 321 is arranged opposite to the background surface 3221, the crimping terminal camera 321 can take pictures of the background surface 3221 and the wire harness at the background surface 3221, thereby determining the effect of the crimping terminal of the wire harness.

[0033] It is understandable that by setting a background surface 3221, the background surface 3221 can serve as the background when the crimping terminal imaging device 321 photographs the wire harness, thereby facilitating the crimping terminal imaging device 321 to determine the effect of the crimping terminal of the wire harness and avoiding interference from other backgrounds on the detection.

[0034] It should be noted that determining the processing effect of a product through photography is a mature technology. Therefore, the improvement of this application is not about how to determine the crimping effect based on the photographed image, but about applying the crimping imaging component to the detection of the crimping effect.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, the crimping terminal imaging device 321 includes a crimping terminal mounting base 3211, a crimping terminal camera 3212, and a crimping terminal cover 3213. The crimping terminal camera 3212 and the crimping terminal cover 3213 are both connected to the crimping terminal mounting base 3211. The crimping terminal cover 3213 covers the crimping terminal imaging base 322. The crimping terminal cover 3213 forms a crimping terminal detection channel 3214. The crimping terminal camera 3212 can detect the effect of crimping the wire harness terminals through the crimping terminal detection channel 3214.

[0036] It is understood that the crimping cover 3213 is located above the crimping camera 322, meaning the crimping cover 3213 is positioned opposite the crimping base. Consequently, the crimping cover 3213 is positioned opposite the wire harness at the crimping base, allowing the wire harness to be observed through the crimping detection channel 3214. The crimping camera 3212 can then capture images of the wire harness through the crimping detection channel 3214. In other words, the crimping camera 3212 can determine the crimping effect of the wire harness by analyzing the images captured through the crimping detection channel 3214, effectively reducing external interference and allowing the crimping camera 3212 to capture images only through the crimping detection channel 3214.

[0037] Specifically, the crimp terminal detection assembly 32 further includes an illumination element, the crimp terminal cover 3213 forms a crimp terminal cavity communicating with the crimp terminal detection channel 3214, and the illumination element is disposed in the crimp terminal cavity and spaced apart from the crimp terminal detection channel 3214.

[0038] It is understandable that by providing lighting, the lighting can provide light for the crimping terminal camera 3212 to capture images, thereby ensuring the shooting effect of the crimping terminal camera 3212.

[0039] It is understandable that placing the lighting element inside the crimping cavity of the crimping cover 3213 can reduce light leakage from the lighting element and ensure the lighting effect of the lighting element. At the same time, the lighting element and the crimping detection channel 3214 are set up to avoid obstructing the shooting of the crimping camera 3212.

[0040] In some embodiments, such as Figure 3 and Figure 4 As shown, the terminal crimping detection assembly 32 includes a terminal crimping connecting plate 323. The first end of the terminal crimping connecting plate 323 is connected to the terminal crimping cover 3213. The second end of the terminal crimping connecting plate 323 forms a third connecting structure. The terminal crimping mounting base 3211 forms multiple fourth connecting structures. The distance between different fourth connecting structures and the terminal crimping camera base 322 is different. The third connecting structure can be connected to different fourth connecting structures.

[0041] It is understandable that the third connection structure of the crimp terminal connecting plate 323 can be connected to the fourth connection structure of the crimp terminal mounting base 3211 to connect the crimp terminal cover 3213 and the crimp terminal mounting base 3211 together.

[0042] Different fourth connection structures have different distances from the crimp terminal detector 322. By connecting the third connection structure to different fourth connection structures, the distance between the crimp terminal cover 3213 and the crimp terminal detector 322 can be changed. In other words, the distance between the crimp terminal detection channel 3214 and the wire harness can be adjusted to meet different requirements.

[0043] For example, the third and fourth connection structures are, for instance, connection holes.

[0044] In some embodiments, the crimp terminal mounting base 3211 is connected to the crimp terminal assembly 31.

[0045] It is understandable that by connecting the crimping terminal mounting base 3211 to the crimping terminal assembly 31, the crimping terminal camera 3212 is arranged adjacent to the crimping terminal assembly 31, thus shortening the distance between the crimping terminal detection assembly 32 and the crimping terminal assembly 31.

[0046] Understandably, connecting the crimping terminal mounting base 3211 to the crimping terminal assembly 31 enables the crimping terminal mounting base 3211 and the crimping terminal camera 3212 to be suspended, which helps to save space.

[0047] In some embodiments, such as Figure 3 and Figure 4 As shown, the heat shrink assembly 33 includes a heat shrink machine 331 and a cooling fan 332. The heat shrink machine 331 forms a heat shrink space 333. The cooling fan 332 is connected to the heat shrink machine 331 and is used to drive the gas flow in the heat shrink space 333.

[0048] Understandably, when the wire harness moves into the heat shrinking space 333, the heat shrinking machine 331 heat shrinks the wire harness with crimped terminals, thus realizing the automatic heat shrinking operation of the wire harness.

[0049] Understandably, after the heat shrink machine 331 heat shrinks the wire harness, the cooling fan 332 can drive the air flow in the heat shrink space 333 to accelerate the air flow speed in the heat shrink space 333, so that the terminals can be cured quickly, so that the wire harness can be moved directly to the next station.

[0050] In some examples, the crimping assembly 31 includes a crimping machine for crimping terminals onto wire harnesses.

[0051] According to an embodiment of the second aspect of this application, the busbar welding machine includes the aforementioned crimping terminal device.

[0052] According to the bus welding machine of this application embodiment, the crimping terminal assembly 31 can perform the crimping terminal operation on the wire harness. After the crimping terminal operation is completed on the wire harness, the wire harness is moved to the crimping terminal detection assembly 32, which detects the effect of the crimping terminal to determine whether the effect of the crimping terminal meets the requirements. If the effect of the crimping terminal meets the requirements, the wire harness with crimped terminals is moved to the heat shrink assembly 33, which heat shrinks the wire harness to improve the connection stability between the terminals and the wire harness. In other words, this application realizes the automated processing of wire harness crimping terminals, the automated detection of the effect of wire harness crimping terminals, and the automated heat shrinking of wire harnesses with crimped terminals, effectively improving the automation level of the crimping terminal device.

[0053] In some embodiments, such as Figure 1 and Figure 2As shown, the busbar welding machine also includes a sleeve device, which includes a sleeve conveying assembly 21, a sleeve cutting assembly 22, a sleeve clamping assembly 23, and a sleeve moving assembly 24. The 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 sleeved on the wire harness.

[0054] According to the sleeve device of this application embodiment, the sleeve conveying component 21 can realize the automatic conveying of the sleeve, and the sleeve cutting component 22 can realize the automatic cutting of the sleeve. Through the cooperation of the sleeve conveying component 21 and the sleeve cutting component 22, the sleeve can be precisely cut to obtain a sleeve segment of the target length. When the sleeve cutting component 22 cuts the sleeve, the sleeve clamping component 23 clamps the sleeve to prevent the sleeve segment from falling off. Then, the sleeve moving component 24 drives the sleeve clamping component 23 to move, so that the sleeve segment moves together to the wire harness. Then, the sleeve moving component 24 continues to drive the sleeve clamping component 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.

[0055] In some embodiments, such as Figure 1 and Figure 2 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.

[0056] 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.

[0057] Specifically, such as Figure 1 and Figure 2 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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, so that the structural layout of the sleeve device is more compact.

[0063] In some embodiments, such as Figure 1 and Figure 2 As shown, the sleeve device also includes a marking component 25, which is located above the sleeve conveying component 21 and is used to mark the sleeve.

[0064] Understandably, marking the casing with the marking component 25 enables automated marking of the casing, thereby improving the automation level of the casing device.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] In some embodiments, such as Figure 1 and Figure 2 As shown, the casing device also includes a casing delivery conduit 26, which is located on the side of the casing delivery assembly 21 away from the casing shearing assembly 22. The casing delivery conduit 26 forms a casing delivery cavity, which is used to guide the casing to move to the casing delivery assembly 21.

[0070] 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.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the cannula 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 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 the cannula shearing assembly 22. The cannula shearing assembly 22 is used to shear the cannula.

[0072] According to the cannulation device of this application embodiment, the cannulation delivery cavity of the cannulation delivery conduit 26 is used for cannulation insertion to guide the cannulation, allowing the cannulation to move precisely to the cannulation delivery assembly 21. The cannulation delivery assembly 21 then moves the cannulation to the cannulation cutting assembly 22, which cuts the cannulation to obtain a cannulation segment of the target length. In other words, this application can guide the cannulation through the cannulation delivery conduit 26, accurately delivering the cannulation to the cannulation delivery assembly 21. The cannulation delivery assembly 21 enables automatic cannulation delivery, and the cannulation cutting assembly 22 enables automatic cutting of the cannulation. Through the cooperation of the cannulation delivery assembly 21 and the cannulation cutting assembly 22, the cannulation can be precisely cut to obtain a cannulation segment of the target length, ensuring that the length of the cannulation segment for different wire harnesses is the same, thereby effectively improving the automation level of cannulation processing.

[0073] In some embodiments, such as Figure 1 and Figure 2 As shown, the cannula delivery conduit 26 has a notch 261 that communicates with the cannula delivery cavity.

[0074] 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.

[0075] In some embodiments, such as Figure 1 and Figure 2 As shown, the sleeve conveying assembly 21 includes at least two sleeve feeding wheels 211, which are arranged opposite to each other.

[0076] 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.

[0077] In some embodiments, such as Figure 1 and Figure 2 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.

[0078] 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.

[0079] In some embodiments, such as Figure 1 and Figure 2 As shown, the casing 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.

[0080] 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.

[0081] In some embodiments, such as Figure 1 and Figure 2 As shown, the cannula device also includes a tube shortage detection component 28, which is located on the side of the cannula delivery conduit 26 away from the cannula delivery component 21. The tube shortage detection component 28 is used to detect whether there is a cannula at the cannula delivery conduit 26.

[0082] 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.

[0083] Specifically, such as Figure 1 and Figure 2 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.

[0084] 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.

[0085] 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...

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.
