Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pole piece coating, specifically relates to an online pole piece sampling device. BACKGROUND

[0002] When coating work is carried out in a lithium battery coating machine, first, trial piece production needs to be carried out and sampling detection needs to be carried out, so as to confirm whether the debugging parameter of the equipment reaches the process set value, and in the process of trial piece sampling, generally, an integral piece is cut down manually, then a piece puncher is used to punch a piece to carry out weighing test, the pole piece on the machine head is reattached with adhesive tape, this kind of mode is not only low in efficiency, but also cannot guarantee complete alignment when reattaching the tape, so problems such as pole piece wrinkling or tape breakage due to poor reattachment of the tape are prone to occur in the next trial piece or production. SUMMARY

[0003] Therefore, the utility model provides an online pole piece sampling device to solve the problems of low efficiency of manual sampling and easy wrinkling or breakage of the pole piece after manual sampling.

[0004] The utility model provides an online pole piece sampling device, which comprises:

[0005] A rack;

[0006] A plurality of support plates sequentially and continuously form a support frame in a head-tail manner; the support frame is slidably connected to the rack along the height direction of the rack;

[0007] A pole piece supporting roller is arranged on one side of the support frame to support the pole piece;

[0008] A sampler is arranged in the support frame and above the pole piece supporting roller;

[0009] The online pole piece sampling device has a first state and a second state, in the first state, the sampler abuts against the pole piece on the pole piece supporting roller and performs sampling operation, and in the second state, a gap is left between the sampler and the pole piece on the pole piece supporting roller.

[0010] Beneficial effects: when the online pole piece sampling device is used to sample the pole piece, the support frame only needs to be moved downward along the height direction of the rack to abut the sampler with the pole piece, so that the sampling operation of the pole piece can be quickly and accurately completed, and the sampling efficiency is improved. In contrast, the existing manual sampling method is complex and inefficient. When manually operated, a specific area of the continuous pole piece material needs to be accurately cut first, and then the cut piece needs to be sampled again. Compared with this, it undoubtedly increases the operation steps and time cost, and in the whole process, due to the interference of human factors, various problems such as size deviation of the cut piece and inaccurate sampling position are easy to occur, which seriously affects the sampling quality and the reliability of subsequent detection and analysis. In addition, since the continuous pole piece is cut off during manual sampling, in order to ensure that the pole piece can continue to be conveyed, the disconnected part of the pole piece needs to be reattached with adhesive tape to rebuild the continuity of the pole piece. However, due to the interference of human factors, the reattached pole piece often has problems such as wrinkles, loose tape and broken tape, which seriously affects the continuity of the production process. In contrast, when the online pole piece sampling device is used to sample the pole piece, the sampler only takes a certain size of sample from the local area of the pole piece, and this process does not cause the pole piece to break, so it does not affect the continuity and flatness of the pole piece, and improves the continuity of the production process.

[0011] In an optional embodiment, a driving member is further included, which is in transmission cooperation with the support frame and drives the support frame to reciprocate along the height direction of the rack.

[0012] Beneficial effects: the height position of the support frame can be accurately and flexibly adjusted by the driving of the driving member, so that the relative position of the sampler and the pole piece on the pole piece roller can be more accurately controlled, further improving the accuracy of the sampling operation and ensuring that the sampled sample can better meet the detection requirements. In addition, compared with manually moving the support frame, using the driving member to drive can greatly improve the automation degree and work efficiency of the whole sampling process, and reduce the errors and instability that may be caused by manual operation.

[0013] In an optional embodiment, the driving member is a pneumatic cylinder, the extension end of the pneumatic cylinder is connected with a first sliding block, and the rack is provided with a first sliding rail in sliding cooperation with the sliding block, the first sliding rail extending along the height direction of the rack.

[0014] Beneficial effects: The cylinder has good power output characteristics and can accurately and stably control the extension and retraction action, thereby realizing accurate driving of the support frame along the height direction of the rack. Secondly, through the sliding fit design of the first sliding block and the first sliding rail, smooth and stable guidance is provided for the reciprocating motion of the support frame. On the one hand, this matching mode can effectively limit unnecessary shaking or deviation of the support frame in other directions, ensure its linear motion in the height direction, make the sampler more stable when approaching or moving away from the pole piece, and avoid damage to the pole piece or sampling error caused by shaking. On the other hand, the sliding fit also reduces the friction during movement, reduces energy loss and component wear, not only prolongs the service life of the device, but also helps to improve the overall operation efficiency of the device, so that the entire pole piece sampling process can be carried out more efficiently and stably.

[0015] In an optional embodiment, the driving members are a pair, and the pair of driving members are located at the bottom of the support frame and are respectively located at both ends of the support frame.

[0016] Beneficial effects: A pair of driving members are respectively located at both ends of the support frame, which can provide more balanced driving force and avoid uneven stress, tilting or shaking of the support frame caused by single-point driving. In this way, the movement of the support frame can be more stable and smooth, and the sampler located in the support frame can always maintain an accurate and stable positional relationship when approaching or moving away from the pole piece on the pole piece supporting roller, ensuring the accuracy of the sampling operation.

[0017] In an optional embodiment, the support frame is provided with a pair of mounting plates on opposite sides, and the pole piece supporting roller is arranged between the pair of mounting plates away from the support frame, and the pole piece supporting roller is connected with the mounting plates.

[0018] Beneficial effects: By installing mounting plates on both sides of the support frame, stable support can be provided for the pole piece supporting roller, ensuring that the position of the pole piece supporting roller is constant when carrying the pole piece, avoiding displacement of the pole piece caused by shaking of the pole piece supporting roller, and thereby ensuring accurate sampling operation.

[0019] In an optional embodiment, the mounting plate comprises a first support plate and a second support plate arranged perpendicularly to the first support plate, one of the first support plate and the second support plate is connected with the support frame, and the other is connected with the pole piece supporting roller.

[0020] Beneficial effects: the first and second support plates are perpendicular to each other, forming a stable support structure that can better withstand various forces generated by the pole piece roller during operation. Further, when the pole piece is placed on the roller and the roller is operated, the stable mounting plate structure can ensure that the entire device will not deform or loosen due to stress, thereby ensuring the smooth operation of the pole piece on the roller and the smooth operation of the sampling operation.

[0021] In an alternative embodiment, the first support plate and the second support plate are integrally formed.

[0022] Beneficial effects: the integrally formed structure greatly enhances the mechanical strength and stability of the mounting plate as a whole, there is no joint gap or weak connection point, and it can better withstand various complex stresses transmitted by the pole piece roller. Whether it is the weight of the pole piece, the lateral force during rotation, or the additional force due to equipment vibration, it can be stably dispersed and carried, effectively preventing the mounting plate from deforming and breaking, thereby ensuring the smooth operation of the pole piece on the roller and the high precision and high reliability of the sampling operation.

[0023] In an alternative embodiment, the sampler is in sliding connection with the support frame, and the sliding direction of the sampler is perpendicular to the conveying direction of the pole piece.

[0024] Beneficial effects: the sliding direction of the sampler is perpendicular to the conveying direction of the pole piece, so that the sampler can move horizontally along a path perpendicular to the conveying direction of the pole piece, thereby sampling in the width direction of the pole piece, improving the flexibility and coverage of the sampling.

[0025] In an alternative embodiment, a lead screw and a motor connected to the lead screw are further included, the lead screw is arranged on the support frame and extends along the sliding direction of the sampler; the sampler is in sliding cooperation with the lead screw through a sliding block.

[0026] Beneficial effects: by driving the lead screw to rotate, the rotational motion of the motor can be accurately converted into the linear motion of the sampler in a specific direction (perpendicular to the conveying direction of the pole piece). This precise control allows the sampler to accurately position the sampling point on the pole piece, whether it is for detecting and sampling a specific area of the pole piece or adjusting the sampling position according to different process requirements, which greatly improves the accuracy and reliability of the sampling, ensuring that the sampled sample accurately reflects the characteristics of the pole piece.

[0027] In an alternative embodiment, a second sliding rail is further provided on the support frame, the second sliding rail extends along the sliding direction of the sampler, and the sampler is in sliding cooperation with the second sliding rail through a second sliding block.

[0028] Beneficial effect: when the sampler is sliding in the direction perpendicular to the direction of the pole piece conveying, the sliding cooperation between the second sliding rail and the second sliding block can effectively limit the unnecessary shaking or deviation of the sampler in other directions, ensuring its smooth movement along the predetermined straight line. In this way, during the sampling process, the sampler can always accurately position the target area on the pole piece for sampling, greatly improving the accuracy and reliability of the sampling, effectively avoiding the sampling error caused by the unstable position of the sampler.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0037] The online pole piece sampling device aims at solving the problems of low efficiency of manual sampling and wrinkles or breakage of pole pieces caused by manual sampling.

[0038] The embodiments of the present application are described below in combination with Figures 1 to 4 .

[0039] According to the embodiments of the present application, as shown in Figures 1 to 3 , an online pole piece sampling device is provided, comprising a rack, a plurality of support plates 1, a pole piece supporting roller 3 and a sampler 4.

[0040] Specifically, the plurality of support plates 1 are sequentially and continuously connected at the head and tail to form a support frame 2; the support frame 2 is slidingly connected with the rack along the height direction of the rack; the pole piece supporting roller 3 is used for supporting the pole piece 11 and is located at one side of the support frame 2; the sampler 4 is located in the support frame 2 and is not above the pole piece supporting roller 3; the online pole piece sampling device has a first state and a second state; in the first state, the sampler 4 abuts against the pole piece 11 on the pole piece supporting roller 3 and performs sampling operation; in the second state, a gap is left between the sampler 4 and the pole piece 11 on the pole piece supporting roller 3.

[0041] When the online pole piece sampling device of the present application is used to sample the pole piece 11, the sampler 4 only needs to abut against the pole piece 11 by moving the support frame 2 downward along the height direction of the rack, so that the sampling operation on the pole piece 11 can be quickly and accurately completed, and the sampling efficiency is improved. In contrast, the existing manual sampling method is complex and inefficient. During manual operation, a specific area of the continuous pole piece 11 material needs to be accurately cut first, and then the cut piece needs to be sampled again. Compared with this, the operation steps and time cost are undoubtedly increased, and various problems such as size deviation of the cut piece and inaccuracy of the sampling position are easily caused due to human factors during the whole process, which seriously affects the sampling quality and the reliability of subsequent detection and analysis. In addition, since the continuous pole piece 11 is cut off during manual sampling, the continuity of the pole piece 11 needs to be restored by re-adhering the cut part of the pole piece 11 with adhesive tape. However, due to human factors, the re-adhered pole piece 11 often has problems such as wrinkles, poor adhesion of the adhesive tape and broken tape, which seriously affects the continuity of the production process. In contrast, when the online pole piece sampling device of the present application is used to sample the pole piece 11, the sampler 4 only takes a sample of a certain size from a local area of the pole piece 11, and this process does not cause the pole piece 11 to break, so the continuity and flatness of the pole piece 11 are not affected, and the continuity of the production process is improved.

[0042] According to an embodiment of the present application, as shown in Figure 1 , Figure 3 and Figure 4Also shown is a driving member 5 in driving cooperation with the support frame 2, the driving member 5 driving the support frame 2 to reciprocate along the height direction of the rack. The driving of the driving member 5 can accurately and flexibly adjust the height position of the support frame 2, so that the relative position of the sampler 4 and the pole piece 11 on the pole piece carrier 3 can be more accurately controlled, further improving the accuracy of the sampling operation and ensuring that the sampled sample can better meet the detection requirements. In addition, compared with manually moving the support frame 2, the use of the driving member 5 can greatly improve the automation degree and work efficiency of the entire sampling process and reduce errors and instability that may be caused by manual operation. It should be noted that the height direction of the rack in the embodiment is consistent with the direction shown in Figure 1 and Figure 3 .

The pneumatic cylinder has good power output characteristics and can accurately and stably control the telescopic action, thereby realizing accurate driving of the support frame 2 along the height direction of the rack. Secondly, the sliding cooperation of the first sliding block 6 and the first sliding rail 7 provides smooth and stable guidance for the reciprocating movement of the support frame 2. On the one hand, this cooperation can effectively limit unnecessary shaking or deviation of the support frame 2 in other directions, ensure linear movement of the support frame 2 in the height direction, and make the sampler 4 move more stably when approaching or moving away from the pole piece 11, thereby avoiding damage to the pole piece 11 or sampling errors caused by shaking. On the other hand, the sliding cooperation also reduces the friction in the movement process, reduces energy loss and component wear, prolongs the service life of the device, and helps to improve the overall operation efficiency of the device, so that the entire pole piece 11 sampling process can be carried out more efficiently and stably. It should be noted that the height direction of the rack in the embodiment is consistent with the direction shown in Figure 1 and Figure 3 .

A pair of driving member 5 is respectively located at both ends of the support frame 2, which can provide more balanced driving force, avoid uneven stress of the support frame 2 caused by single-point driving, and avoid tilting or shaking and other conditions. In this way, the movement of the support frame 2 can be more stable and smooth, and the sampler 4 located in the support frame 2 can always maintain an accurate and stable positional relationship when approaching or moving away from the pole piece 11 on the pole piece roller 3, ensuring the accuracy of the sampling operation.

[0045] According to an embodiment of the utility model, Figure 1 As shown, the opposite sides of the support frame 2 are provided with a pair of mounting plates 8, and the pole piece roller 3 is arranged between the mounting plates 8 away from the support frame 2, and the mounting plate 8 is connected with the pole piece roller 3. By installing the mounting plate 8 on both sides of the support frame 2, the pole piece roller 3 can be stably supported, and the position of the pole piece roller 3 can be kept constant when carrying the pole piece 11, so that the pole piece 11 is not displaced due to the shaking of the pole piece roller 3, and the sampling operation is accurate and reliable.

The first support plate 801 and the second support plate 802 are perpendicular to each other, forming a stable support structure, which can better withstand various forces generated by the pole piece roller 3 during operation. In addition, when the pole piece 11 is placed on the roller and the roller is rotated, the stable mounting plate 8 structure can ensure that the entire device will not deform or loosen due to stress, thereby ensuring the stable operation of the pole piece 11 on the roller and the smooth operation of the sampling operation.

[0047] According to an embodiment of the utility model, Figure 3 And Figure 4 As shown, the first support plate 801 and the second support plate 802 are integrally formed. The integrally formed structure greatly enhances the mechanical strength and stability of the mounting plate 8 as a whole, and there is no splicing gap or weak connection point, which can better withstand various complex stresses transmitted by the pole piece roller 3. Whether it is the weight of the pole piece 11, the lateral force during rotation, or the additional force generated by the equipment vibration, it can be stably dispersed and carried, effectively preventing the mounting plate 8 from deforming and breaking, thereby ensuring the stable operation of the pole piece 11 on the roller and the high precision and high reliability of the sampling operation.

[0048] According to an embodiment of the utility model, Figures 1 to 3As shown, the sampler 4 is in sliding connection with the support frame 2, and the sliding direction of the sampler 4 is perpendicular to the conveying direction of the pole piece 11. The sliding direction of the sampler 4 is perpendicular to the conveying direction of the pole piece 11, so that the sampler 4 can be accurately moved transversely along a path perpendicular to the conveying direction of the pole piece 11, thereby sampling in the width direction of the pole piece 11, improving the flexibility and coverage of sampling.
