DETAILED DESCRIPTION

[0037] In order to prevent the jitter of the material strip from causing uneven coating thickness and increased production costs, the prior art usually adopts multiple sampling of the pole piece along the length direction of the material strip to determine the jitter of the material strip. However, if there is a difference in the coating thickness of the material strip of the same width during the material strip coating process, the above-mentioned prior art cannot measure it, and the detection position adopts fixed-point positioning for detection and acquisition of data, which has the problem of singleness, and the production reference feedback is inaccurate.

[0038] To this end, an embodiment of the utility model discloses a material belt jitter detection device, which solves the technical problem that when the material belt jitters, the existing contact-type jitter detection means cannot move with the jitter of the material belt and is difficult to accurately detect the jitter amplitude.

[0039] See also Figure 1 , a structural schematic diagram of a material belt jitter detection device provided in an embodiment of the utility model.

[0040] The utility model provides a material belt vibration detection device, comprising a mounting frame 1 and at least one detection component 2;

[0041] The mounting frame 1 is connected across two sides of the material belt conveying mechanism;

[0042] The detection component 2 is slidably mounted on the mounting frame 1 and is used to collect jitter data of the material belt transported by the material belt conveying mechanism.

[0043] The material strip can be a pole piece or a metal current collector that is rolled into a metal strip of a certain thickness by a roller.

[0044] In the production process of lithium-ion batteries, slurrying, coating and rolling are the three key processes for the preparation of its pole pieces. The positive and negative active materials, conductive agents, binders, etc. are made into slurry, coated on copper / aluminum foil, dried, rolled and compacted to obtain positive and negative electrodes, which constitute the electrochemical reaction carrier and the core of the entire battery. The electrode manufacturing process affects the porosity, thickness, density of the positive and negative electrodes, as well as the microstructures such as the conductive network and the bonding network, which largely determines the performance of lithium-ion batteries.

[0045] To this end, it is necessary to monitor the entire process of electrode preparation in real time. During the electrode preparation process, the material belt is usually moved to the position of each process by a material belt conveyor mechanism. The material belt jitter detection device composed of a mounting frame 1 and at least one detection component 2 can be set at any position to flexibly detect the material belts of different processes, so as to obtain a variety of jitter data to meet production reference needs.

[0046] Specifically, in an embodiment of the utility model, the mounting frame 1 is installed along the width direction of the material belt, straddling the two sides of the material belt conveying mechanism and fixing its position. By sliding at least one detection component 2 on the mounting frame 1, the detection component 2 is moved to different positions of the mounting frame 1 at the same width to collect jitter data corresponding to each point at the same width position of the material belt.

[0047] It should be noted that the jitter data can be the thickness detected by the detection component 2, the height from the material strip, or other data that can be directly detected by the sensor, and the embodiment of the utility model does not limit the data type. Taking the detection mechanism 21 in the detection component 2 as a laser detection component as an example, the laser detection component can be fixed on the test bench and its distance from the pole piece to be tested can be adjusted to ensure that the laser beam can correctly irradiate the pole piece surface. Then, through the operation of the control system, the laser detection component scans the pole piece and records the displacement data of each point. By processing and analyzing the displacement data, the thickness distribution of the pole piece can be obtained. Among them, the laser detection component can specifically be a laser displacement sensor.

[0048] In one example of the present utility model, the material belt jitter detection device further includes two sets of equipment brackets arranged along the conveying direction of the material belt conveying mechanism;

[0049] The equipment bracket is provided with a plurality of embedding holes arranged in pairs for embedding the mounting frame 1 .

[0050] In order to improve the installation stability of the material belt jitter detection device, the mounting frame 1 can be further fixed by the equipment brackets arranged on both sides of the material belt conveyor mechanism. Specifically, two sets of equipment brackets can be arranged along the conveying direction of the material belt conveyor mechanism, and a plurality of embedded holes arranged in pairs are opened on the equipment brackets in opposite directions. A fixing piece matching the embedded hole is provided on the mounting frame 1, and the fixing piece can be arbitrarily embedded in the embedded hole through the fixing piece to move the detection position of the device.

[0051] Among them, the equipment bracket can be selectively installed in the length direction of the material belt conveying mechanism.

[0052] like Figure 1 As shown, optionally, the mounting frame 1 includes a slide rail assembly 11 and a fixing assembly 12;

[0053] The fixing assembly 12 is detachably connected to both ends of the slide rail assembly 11 , and the fixing assembly 12 is used to fix the cross-connection position of the mounting frame 1 .

[0054] In this embodiment, the mounting frame 1 includes a slide rail assembly 11 and two sets of fixing assemblies 12. The fixing assemblies 12 are detachably mounted on both ends of the slide rail assembly 11. The slide rail assembly 11 spans the material strip along the width direction of the material strip. The above-mentioned fixing parts matching the embedding holes are arranged on the fixing assembly 12, and the fixing parts are embedded in the equipment bracket to fix the detection position of the slide rail assembly 11.

[0055] Furthermore, the slide rail assembly 11 is provided with a transverse slide rail and a transverse inner cavity 111;

[0056] The detection assembly 2 is sleeved on the slide rail assembly 11 and can move to a target position along the transverse slide rail.

[0057] In order to realize the movement of the detection component 2 at any position on the same width of the material strip, the slide rail component 11 can be provided with a hollow transverse inner cavity 111, and a transverse slide rail is also provided on the slide rail component 11. By sleeve-mounting the detection component 2 on the slide rail component 11, and the detection component 2 is slidably connected with the transverse slide rail, the detection component 2 can be moved to the target position along the transverse slide rail. The transverse slide rail can be formed by opening along the width direction of the material strip.

[0058] The transverse inner cavity 111 is used to accommodate the connecting wire group 24 associated with the detection component 2;

[0059] One end of the connecting wire group 24 is connected to the detection component 2 , and the other end passes through the transverse inner cavity 111 to be connected to the processing terminal.

[0060] It should be noted that the connecting wire group 24 may include at least one connecting wire, and the connecting wire type may include but is not limited to data transmission lines, power supply wires or various connecting wires required to realize the functions of the detection components. By accommodating the connecting wire group 24 in the transverse inner cavity 111, it is convenient to manage various connecting wires, and at the same time avoid the safety risk of the connecting wires being entangled in the material belt conveying mechanism.

[0061] like Figure 2 As shown, in one example of the present utility model, the slide rail assembly 11 further includes a driving assembly 14 accommodated in the transverse inner cavity 111;

[0062] The driving assembly 14 is rigidly connected to the detection assembly 2 and is used to drive the detection assembly 2 to move to the target position along the transverse slide rail and fix it.

[0063] In order to realize the movement of the detection component 2, the slide rail component 11 may also include a driving component 14 accommodated in the transverse inner cavity 111, the driving component 14 is rigidly connected to the detection component 2, and the detection component 2 is driven to move to the target position along the transverse slide rail by moving the driving component 14, and the target position of the detection component 2 is fixed when the driving component 14 stops. When the detection component 2 is fixed, the detection component 2 is used to collect data on the vibration of the material belt.

[0064] Optionally, the driving assembly 14 includes a connecting rod and a driving mechanism;

[0065] The connecting rod is rigidly connected to the detection assembly;

[0066] The power output shaft of the driving mechanism is connected to the connecting rod and is used to drive the connecting rod to rotate or extend, so as to drive the detection component to move to the target position and fix it.

[0067] Among them, the connecting rod can be a spiral rod, a lead screw or other telescopic rod, but is not limited to the exemplified connecting rods. The driving mechanism can be a motor or other mechanism. Through the axial connection between the motor and the lead screw, the external motor drives the lead screw to rotate, so as to realize the conversion of the rotational motion of the lead screw into the linear reciprocating motion of the detection component 2, so as to drive the detection component 2 to move along the transverse slide rail to the target position. When the position of the detection component 2 needs to be fixed, the detection component 2 is fixed at the target position by stopping the rotation of the motor.

[0068] like Figure 3 As shown, in another example of the present utility model, the detection assembly 2 includes a detection mechanism 21, a mechanism mounting plate 22 and a positioning mechanism 23;

[0069] The mechanism mounting plate 22 is sleeved on the slide rail assembly 11, the detection mechanism 21 is mounted on one side of the mechanism mounting plate 22, and the positioning mechanism 23 is mounted on the other side;

[0070] The positioning mechanism 23 is used to fix the position of the detection mechanism 21 on the transverse slide rail.

[0071] In this embodiment, the detection mechanism 21 is installed on one side of the mechanism mounting plate 22, and the positioning mechanism 23 is installed on the other side of the mechanism mounting plate 22, so that a rigid connection is achieved between the three. By sleeveing ​​the mechanism mounting plate 22 on the slide rail assembly 11, the structure is pulled to slide in a linkage manner on the transverse slide rail.

[0072] The positioning mechanism 23 and the detection mechanism 21 are movably connected, and the detection mechanism 21 can be fixed or loosened on the transverse slide rail by rotating the positioning mechanism 23 .

[0073] like Figure 3 and Figure 4 As shown, further, the device also includes a traction assembly 13;

[0074] The mechanism mounting plate 22 is provided with at least one first traction sleeve hole 211, and the positioning mechanism 23 is provided with at least one second traction sleeve hole 212;

[0075] The traction assembly 13 is used to hook the first traction sleeve hole 211 and pull the detection assembly 2 along the transverse slide rail to the target position, and then hook the second traction sleeve hole 212 in sequence in a clockwise or counterclockwise direction to fix the detection assembly 2.

[0076] Specifically, a first traction sleeve hole 211 is provided on the mechanism mounting plate 22, and at least one second traction sleeve hole 212 is provided on the positioning mechanism 23. The first traction sleeve hole 211 can be respectively arranged at the upper end and the lower end of the mechanism positioning plate. When it is necessary to move the detection component 2, the first traction sleeve hole 211 is hooked through the traction component 13, and the detection component 2 is pulled along the transverse slide rail until it is pulled to the target position, and then the traction component 13 is hooked on the second traction sleeve hole 212 of the positioning mechanism 23 to fix the detection component 2 at the target position.

[0077] After the detection component 2 is fixed at the target position, the detection mechanism 21 on the detection component 2 is used to detect the jitter of the material belt on the material belt conveying mechanism, for example, to detect its thickness, distance and other data, so as to monitor the jitter of the material belt during movement in real time.

[0078] In an embodiment of the utility model, a material belt jitter detection device is provided, which includes a mounting frame and at least one detection component; the mounting frame is connected across the two sides of the material belt conveyor mechanism; the detection component is slidably mounted on the mounting frame, and is used to collect jitter data of the material belt transported by the material belt conveyor mechanism. The slide rail component spans across the two sides of the material belt, and the detection component is slidably arranged on the slide rail, and an inner cavity is arranged on the slide rail for the line body or the driving component to pass through. After the detection component is driven to move to the target position on the slide rail, the jitter data of the material belt on the material belt conveyor mechanism is detected in real time through the detection component, so as to accurately and flexibly monitor the jitter of the material belt at different positions during the production process.
