Description

Technical Field

[0001] The utility model belongs to the technical field of battery pole piece production, and in particular relates to a battery pole piece clamping and conveying device and coating equipment. Background Art

[0002] Currently, in the early stages of battery electrode coating production, a rubber roller clamping mechanism is typically used as a tension barrier. However, this mechanism often results in uneven pressure at both ends of the roller, leading to inconsistent linear speeds for electrode clamping and causing problems such as wrinkling and deviation of the electrode. Furthermore, this uneven distribution of pressure can lead to varying degrees of wear on the roller surface, shortening its service life.

[0003] In the existing technology, the clamping force of the rubber pressure roller clamping mechanism is mostly adjusted manually. The adjusted clamping force has no quantitative feedback, which makes the adjustment operation difficult. It often takes multiple adjustments to achieve the ideal effect, but frequent adjustments greatly affect the production efficiency of the electrode. Utility Model Content

[0005] In view of this, the present invention provides a battery electrode clamping and feeding device, comprising:

[0006] Two brackets, each of which is provided with a swing arm, and the two swing arms are rotatably connected to the two brackets;

[0007] The transmission roller mechanism includes a transmission roller and a first driving member. The transmission roller is rotatably mounted on the bracket. The first driving member is mounted on the bracket and is used to control the rotation of the transmission roller.

[0008] The rubber pressure roller mechanism includes a rubber pressure roller, two through-shaft tension sensors, and two second driving members. The two through-shaft tension sensors are respectively mounted on two swing arms. The two ends of the rubber pressure roller are rotatably connected to the two through-shaft tension sensors. The two second driving members are mounted on the bracket and are respectively used to control the rotation of the two swing arms to drive the rubber pressure roller toward or away from the transmission roller.

[0009] Two regulators, the two regulators are respectively mounted on the two brackets and are respectively used to control and adjust the output pressures of the two second driving members;

For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0029] Example 1:

[0030] This embodiment provides a battery electrode clamping and feeding device, comprising:

[0031] Two brackets 1, each of which is provided with a swing arm 2, and the two swing arms 2 are rotatably connected to the two brackets 1;

[0032] The transmission roller mechanism includes a transmission roller 3 and a first driving member 4. The transmission roller 3 is rotatably mounted on the bracket 1. The first driving member 4 is mounted on the bracket 1 and is used to control the rotation of the transmission roller 3.

[0033] The rubber pressure roller mechanism includes a rubber pressure roller 5, two through-shaft tension sensors 6, and two second drive members 7. The two through-shaft tension sensors 6 are respectively mounted on the two swing arms 2. The two ends of the rubber pressure roller 5 are rotatably connected to the two through-shaft tension sensors 6. The two second drive members 7 are mounted on the bracket 1 and are respectively used to control the rotation of the two swing arms 2 to drive the rubber pressure roller 5 toward or away from the transmission roller 3.

[0034] Two regulators 8, the two regulators 8 are respectively mounted on the two brackets 1 and are respectively used to control and adjust the output pressures of the two second driving members 7;

[0035] A pinching gap is formed between the driving roller 3 and the pressing roller 5 for the battery pole pieces to pass through.

[0036] Furthermore, an external control system is included, wherein the signal output end of the through-axis tension sensor 6 is connected to the signal input end of the external control system, and the external control system controls the regulator 8 to adjust the output pressure of the second driving member 7.

[0037] In the present technical solution, when the battery electrode clamping device is working, the battery electrode passes through the clamping gap between the transmission roller 3 and the glue pressing roller 5, the first driving member 4 controls the rotation of the transmission roller 3 to pull the battery electrode, and the second driving member 7 controls the swing arm 2 to rotate to drive the glue pressing roller 5 to abut against the battery electrode. The glue pressing roller 5 applies appropriate pressure to the battery electrode to ensure that the electrode passes stably through the gap between the transmission roller 3 and the glue pressing roller 5, thereby realizing the electrode clamping operation.

[0038] The roller shaft of the rubber pressure roller 5 is rotatably connected to a through-axis tension sensor 6 via a bearing. The through-axis tension sensor 6 can directly measure the pressure on the rubber pressure roller 5. When the rubber pressure roller 5 is rolling and pressing the electrode, the signal output end of the through-axis tension sensor 6 is connected to the signal input end of an external control system, which can be a programmable logic controller (PLC). The through-axis tension sensor 6 collects the pressure at both ends of the rubber pressure roller 5 in real time and communicates the collected pressure data to the PLC. The real-time pressure collected in real time is then compared with the preset pressure range written into the human-machine interface to calculate the deviation. The PLC then calculates the output adjustment amount of the second drive member 7 and controls the regulator 8 to adjust the output pressure of the second drive member 7, affecting the rotation amplitude of the swing arm 2, thereby changing the pressure applied by the rubber pressure roller 5 to the electrode, so that the electrode is in a suitable compression state for the tape to pass.

[0039] In summary, the clamping device installs through-axis tension sensors 6 at both ends of the rubber pressing roller 5 used to press the electrode. The through-axis tension sensors 6 monitor the pressure at both ends of the rubber pressing roller 5 in real time and feed it back to the external control system. The external control system automatically adjusts the output pressure of the second drive member 7 through the control regulator 8 based on the monitored pressure, affecting the rotation amplitude of the swing arm 2, changing the pressure applied by the rubber pressing roller 5 on the electrode, and ensuring that the line pressure between the electrode and the rubber pressing roller 5 during the tape passing through the clamping device is consistent. This can avoid inconsistent linear speeds of the electrode clamping due to inconsistent line pressure between the rubber pressing roller 5 and the electrode, effectively prevent different degrees of surface wear of the rubber pressing roller 5, and prevent the electrode from wrinkling, deviation, and other undesirable phenomena during the clamping process, thereby reducing economic losses. At the same time, there is no need to manually adjust the rubber pressing roller 5, reducing labor input, not only improving production efficiency but also enhancing production safety.

[0042] Furthermore, the through-axis tension sensor 6 is detachably mounted on the swing arm 2 .

[0043] Furthermore, the through-axis tension sensor 6 is connected and fixed to the swing arm 2 by setting fasteners.

[0044] In this technical solution, several mounting holes are opened on the swing arm 2, and several connecting holes corresponding to the mounting holes are opened on the through-axis tension sensor 6. Then, the through-axis tension sensor 6 is connected and fixed to the swing arm 2 by setting bolts or screws.

[0045] Example 3:

[0046] This embodiment provides a battery electrode clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] Furthermore, the bracket 1 further includes:

[0048] The bearing is embedded in the bracket 1, and the transmission roller 3 is connected to the bearing.

[0049] In this technical solution, bearings are embedded and installed on the two brackets 1, one end of the roller shaft of the transmission roller 3 is fixedly connected to the bearing on one of the brackets 1, and the other end passes through the bearing of the other bracket 1 and is connected to the driving end of the first driving member 4, so that the transmission roller 3 is rotatably connected to the two brackets 1.

[0050] Furthermore, the first driving member 4 is a motor. The motor is fixed on one of the brackets 1, and the driving end of the motor is connected to the end of the transmission roller 3. The motor is only responsible for controlling the rotation of the transmission roller 3 to provide kinetic energy for the entire pinching device.

[0051] Example 4:

[0052] This embodiment provides a battery electrode clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] Furthermore, the rubber pressure roller mechanism also includes:

The bearing end of the rod end bearing 9 is rotatably connected to the connecting block, and the other end is fixedly connected to the drive end of the second drive member 7. Through this structural design, the second drive member 7 drives the rod end bearing 9 to move, thereby driving the swing arm 2 to rotate, thereby causing the rubber pressure roller 5 to move closer to or farther from the transmission roller 3. The use of the rod end bearing 9 makes the connection between the second drive member 7 and the swing arm 2 more flexible, preventing the swing arm 2 from getting stuck during rotation. At the same time, the rod end bearing 9 can also effectively absorb and reduce vibration, thereby reducing the noise generated during the movement of the swing arm 2.

[0057] This embodiment provides a battery electrode clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0058] Furthermore, the second driving member 7 is a cylinder.

[0059] Furthermore, the regulator 8 is a pneumatic proportional valve.

[0060] In the present technical solution, during the clamping process of the rubber pressure roller 5, two through-axis tension sensors 6 collect the pressure at both ends of the rubber pressure roller 5 in real time, communicate the pressure data to the PLC, and compare it with the preset pressure range written through the human-machine interface to calculate the deviation. Then the PLC automatically calculates the adjustment amount of the pneumatic proportional valve according to the proportional integral differential control (PID control). The specific calculation process is: if the deviation is greater than the unit adjustment amount (the unit adjustment amount refers to the minimum adjustable amount of the pneumatic proportional valve), the PLC automatically sets the adjustment amount to the deviation amount, and sends the adjustment electrical signal to the proportional valve. If the deviation is less than the unit adjustment amount, the PLC automatically sets no adjustment, and controls the extension amount of the cylinder by adjusting the output gas volume of the pneumatic proportional valve, thereby adjusting the pressure at both ends of the rubber roller.
