Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a broken belt catching mechanism of a battery coating machine and the battery coating machine. Background Art

[0002] Battery coater is a coating equipment, mainly used for coating positive and negative electrode materials of lithium batteries. The basic working principle of the coater is to evenly coat the coating on the surface of the conductive material at a certain speed, and dry it in an oven immediately after coating.

[0003] When current battery coating machines are coating electrodes, particles often scrape the electrodes and break them. Once broken, the electrodes are likely to fly into the oven. When splicing, the oven needs to be opened first, and then the broken tape needs to be taken out and then spliced. The above operations are time-consuming and labor-intensive, affecting production efficiency. Utility Model Content

[0004] In order to solve the above problems, the utility model aims to propose a broken tape catching mechanism for a battery coating machine and a battery coating machine, which clamps the electrode piece by arranging a stop plate linked with the lower pressure roller and the electrode piece in cooperation with a support plate, thereby fixing the position of the electrode piece to prevent the broken electrode piece from flying into the oven.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A broken belt catching mechanism of a battery coating machine relates to a pole piece, comprising an oven, wherein the upper and lower ends of the front entrance of the oven are respectively provided with a support plate and a mounting frame, the pole piece passes through the supporting roller of the coating machine and enters the oven close to the support plate for baking and drying, the mounting frame is slidably inserted with a pressure rod, the lower end of the pressure rod is provided with a stop plate, a rotating roller is rotatably installed at the lower part of the mounting frame, a limiting mechanism is installed on one side of the rotating roller, a limiting groove corresponding to the limiting mechanism is provided on the pressure rod, a rotating rod is installed on the other side of the rotating roller, a lower pressure roller is rotatably installed on the rotating rod, and a limiting block is installed on the mounting frame; when the limiting block and the upper surface of the rotating rod are in contact and extruded, the lower pressure roller is pressed tightly against the upper surface of the pole piece, and at this time, the limiting mechanism is engaged with the limiting groove.

[0007] Furthermore, it also includes a tension spring, the upper part of the pressure rod is sleeved with the tension spring, the upper end of the tension spring is connected to the pressure rod, and the lower end of the tension spring is connected to the mounting frame. When the limiting mechanism is engaged with the limiting groove, the tension spring is in a stretched state.

[0008] Furthermore, the stop plate is a rubber plate.

[0009] Furthermore, the limiting mechanism is a wedge block.

[0010] In order to achieve the above-mentioned purpose, the utility model also provides a battery coating machine, including the broken belt catching mechanism of the battery coating machine as mentioned above.

[0011] Beneficial effect: When the pole piece breaks, the tension of the pole piece decreases instantly, and then the tension of the pole piece is insufficient to support the lower pressure roller. The gravity of the lower pressure roller drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating roller to rotate. The rotation of the rotating roller drives the limiting mechanism to rotate. The limiting mechanism rotates to disengage from the limiting groove on the pressure rod, and then the pressure rod moves downward rapidly under the action of gravity, driving the stop plate to cooperate with the support plate to clamp the pole piece, and then fix the position of the pole piece to prevent the broken pole piece from flying into the oven. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The accompanying drawings constituting a part of the present invention are used to provide a further understanding of the present invention. The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the accompanying drawings:

[0013] Figure 1 It is a structural schematic diagram of the broken belt catching mechanism of the battery coating machine described in an embodiment of the utility model. DETAILED DESCRIPTION

[0014] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0016] Example 1

[0017] See also Figure 1 : A broken belt capture mechanism of a battery coating machine, involving a pole piece 1, comprises an oven 2, wherein the upper and lower ends of the front entrance of the oven 2 are respectively provided with a support plate 3 and a mounting frame 4, wherein the pole piece 1 passes through the supporting roller 5 of the coating machine and enters the oven 2 close to the support plate 3 for baking and drying, wherein a pressure rod 6 is slidably inserted on the mounting frame 4, and a stop plate 7 is installed at the lower end of the pressure rod 6, a rotating roller 8 is rotatably installed at the lower part of the mounting frame 4, a limiting mechanism 9 is installed on one side of the rotating roller 8, a limiting groove 601 corresponding to the limiting mechanism 9 is provided on the pressure rod 6, a rotating rod 10 is installed on the other side of the rotating roller 8, a lower pressure roller 11 is rotatably installed on the rotating rod 10, and a limiting block 12 is installed on the mounting frame 4; when the limiting block 12 and the upper surface of the rotating rod 10 are in contact and extruded, the lower pressure roller 11 is pressed tightly against the upper surface of the pole piece 1, and at this time, the limiting mechanism 9 is engaged with the limiting groove 601.

[0018] When the pole piece breaks, the tension of the pole piece decreases instantly, and then the tension of the pole piece is insufficient to support the lower pressure roller. The gravity of the lower pressure roller drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating roller to rotate. The rotation of the rotating roller drives the limiting mechanism to rotate. The limiting mechanism rotates and disengages from the limiting groove on the pressure rod, and then the pressure rod moves downward rapidly under the action of gravity, driving the stop plate to cooperate with the support plate to clamp the pole piece, thereby fixing the position of the pole piece to prevent the broken pole piece from flying into the oven.

[0019] This embodiment uses a purely mechanical structure as the trigger and action mechanism, which has a relatively simple structure and high reliability. In normal times, it is possible to determine whether the device has mechanical damage by observation, thereby facilitating timely discovery of damage.

[0020] In a specific example, it also includes a tension spring 12, and the upper part of the pressure rod 6 is covered with a tension spring 13, the upper end of the tension spring 13 is connected to the pressure rod 6, and the lower end of the tension spring 13 is connected to the mounting frame 4. When the limiting mechanism 9 is engaged with the limiting groove 601, the tension spring 13 is in a stretched state.

[0021] In this embodiment, the tension spring can further improve the movement speed of the pressure rod, so that the stop plate at the lower end of the pressure rod can react quickly and cooperate with the pole piece and the supporting plate to clamp and capture the pole piece in time.

[0022] In a specific example, the stop plate 7 is a rubber plate.

[0023] The rubber plate of this embodiment can increase the friction force when in contact with the upper surface of the pole piece, improve the stopping effect on the pole piece, and better capture the pole piece with a broken belt.

[0024] In a specific example, the limiting mechanism 9 is a wedge block.

[0025] The working principle of this embodiment is as follows: during operation, when the pole piece breaks, the tension of the pole piece decreases instantly, and then the tension of the pole piece is insufficient to support the lower pressure roller, and the gravity of the lower pressure roller drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating roller to rotate, and the rotation of the rotating roller drives the limiting wedge to rotate, and the limiting wedge rotates to disengage from the limiting groove on the pressure rod, and then the pressure rod moves downward rapidly under the action of the tension spring, driving the rubber plate to cooperate with the support plate to clamp the pole piece, and then fix the position of the pole piece to prevent the pole piece from flying into the oven.
