Description

Technical Field

[0001] The utility model belongs to the technical field of pole piece winding, and in particular relates to a winding mechanism and a coating machine. Background Art

[0002] In the coating process of battery pole pieces, a winding mechanism is usually set at the last stage of the coating process to wind the coated pole pieces onto a special reel. In the process of winding the pole pieces, there is a risk of slippage between the winding reel and the chuck of the winding mechanism. Once slippage occurs and the equipment cannot be slowed down and stopped in time, the chuck and the inner wall of the reel will melt into each other and the reel cannot be unloaded. The reel and the chuck can only be separated by cutting the reel. The cut reel cannot be used any more, which increases production costs and affects production efficiency. In addition, the cutting process will also generate powder that poses a great risk of contaminating the quality of the pole pieces and the cleanliness of the workshop environment.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0029] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships.

In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] Embodiment 1:

[0031] This embodiment provides a winding mechanism, including:

[0032] Base frame 1;

[0033] Two chucks 2, which are rotatably mounted on the base frame 1;

[0034] A winding drum 3, which is mounted between the two chucks 2, and a sensing member 4 is provided on the winding drum 3;

[0035] A detection sensor 5, which is mounted on the chuck 2;

[0036] Wherein, when the winding drum 3 is connected to the chuck 2, the detection sensor 5 and the sensing member 4 are aligned and sensed with each other.

[0037] In this technical solution, as Figure 1 shown, the number of chucks 2 is two and both are rotatably mounted on the base frame 1. The two ends of the winding drum 3 are respectively connected and fixed to the two chucks 2. The sensing member 4 provided on the winding drum 3 is aligned and sensed with the detection sensor 5 provided on the chuck 2, and then the motor is used to drive the chuck 2 to rotate, driving the winding drum 3 to rotate to realize the winding operation of the pole piece.

[0038] During the pole piece winding process, if slippage occurs between the winding drum 3 and the chuck 2, the originally aligned sensing member 4 and the detection sensor 5 will be misaligned, and the signal fed back by the detection sensor 5 to the equipment control system will change, so that the control system controls the motor to decelerate and stop urgently, thereby preventing the slippage from intensifying and causing the situation of mutual melting between the inner wall of the winding drum 3 and the chuck 2.

[0039] Furthermore, the number of the sensing elements 4 is several, and the several sensing elements 4 are arranged in an annular array along the circumferential direction of the winding drum 3. Through this structural design, when the winding drum 3 is installed on the chuck 2, the detection sensor 5 of the chuck 2 only needs to be aligned and sensed with one of the sensing elements 4, which helps to quickly connect and fix the winding drum 3 and the chuck 2, and is more convenient and practical.

[0040] In summary, by providing the detection sensor 5 on the chuck 2 and the sensing element 4 capable of inducing with the detection sensor 5 on the winding drum 3, when the winding drum 3 is connected and fixed to the chuck 2, the detection sensor 5 is aligned and sensed with the sensing element 4; when the winding drum 3 and the chuck 2 slip and misalign, the detection sensor 5 feeds back the signal change to the control system to stop the rotation of the chuck 2, effectively avoiding the potential hidden danger of the mutual melting of the inner wall of the chuck 2 and the winding drum 3.

[0041] Embodiment 2:

[0042] This embodiment provides a winding mechanism, which, in addition to including the technical solutions of the above embodiment, further has the following technical features.

[0043] Furthermore, it further includes:

[0044] A first identification member 6, which is arranged on the chuck 2 and corresponds to the detection sensing position;

[0045] Several second identification members 7, which are arranged on the winding drum 3 and correspond to the several sensing elements 4 one by one;

[0046] Wherein, when the detection sensor 5 is aligned and sensed with one of the sensing elements 4, the first identification member 6 and the corresponding second identification member 7 are directly opposite to each other.

[0047] In this technical solution, the first identification member 6 is arranged on the chuck 2 corresponding to the position of the detection sensor 5, and the number of the second identification members 7 is multiple and arranged on the winding drum 3, corresponding to the positions of the several sensing elements 4 one by one. Through this structural design, when installing and connecting the end of the winding drum 3 to the chuck 2, it is convenient for the staff to visually observe whether the detection sensor 5 on the chuck 2 corresponds to the sensing element 4 on the winding drum 3, and ensure that the detection sensor 5 is aligned and sensed with the sensing element 4 to detect the slipping phenomenon between the chuck 2 and the winding drum 3.

[0048] Furthermore, both the first identification member 6 and the second identification member 7 are colored stickers. Selecting colored stickers as the first identification member 6 and the second identification member 7, the colored stickers are simple and convenient to paste on the chuck 2 and the winding drum 3, convenient to replace, and not easy to damage the chuck 2 and the winding drum 3, with high practicability.

[0049] Embodiment 3:

[0050] This embodiment provides a winding mechanism, which, in addition to including the technical solutions of the above embodiments, further has the following technical features.

[0051] Furthermore, it further includes:

[0052] A tray 8, which is liftably installed on the base frame 1 and is located below the reel 3.

[0053] In this technical solution, two trays 8 are provided on the base frame 1. The two trays 8 are respectively located below the two chucks 2 and can be moved and adjusted along the height direction of the base frame 1. The lifting of the tray 8 can be achieved by setting an electric cylinder or a pneumatic cylinder. The two ends of the reel 3 are respectively placed on the two trays 8. By using the rising of the tray 8 to drive the reel 3 to move to the position corresponding to the chuck 2, and then connecting and installing the reel 3 with the chuck 2, it helps the staff to install the reel 3 more conveniently. When disassembling the reel 3 from the chuck 2, controlling the tray 8 to rise can support the reel 3 and avoid the reel 3 accidentally falling during the disassembly process.

[0054] In summary, through this structural design, it is convenient for the staff to load and unload the reel 3, and it can also protect the reel 3 during the loading and unloading process.

[0055] Furthermore, a "V"-shaped trough 9 is provided on the tray 8. The "V"-shaped trough 9 can provide stable support for the end of the reel 3 and guide the upward movement of the reel 3, avoiding the position of the reel 3 from shifting during the rising of the tray 8, ensuring that the positions between the reel 3 and the chuck 2 can be accurately aligned, and facilitating the connection and installation between the reel 3 and the chuck 2.

[0056] Embodiment 4:

[0057] This embodiment provides a winding mechanism, which, in addition to including any one of the technical solutions in the above Embodiments 1-3, further has the following technical features.

[0058] Furthermore, the detection sensor 5 is a magnetic sensor, and the sensing element 4 is a magnetic sheet.

[0059] In this technical solution, the detection sensor 5 can be a magnetic sensor, and the sensing element 4 can be a magnetic sheet. When the magnetic sensor and the magnetic sheet are aligned, the magnetic sensor can sense and detect the magnetic field generated by the magnetic sheet. When slippage occurs between the chuck 2 and the reel 3, the magnetic sensor and the magnetic sheet are misaligned, the magnetic sensor detects a change in the signal magnetic field, and the signal fed back by the magnetic sensor to the control system changes accordingly, so that the winding mechanism decelerates and stops urgently.

[0060] Embodiment 5:

[0061] This embodiment provides a winding mechanism. In addition to including any one of the technical solutions in the above Embodiments 1-3, it also has the following technical features.

[0062] Further, the detection sensor 5 is a photoelectric sensor, and the sensing member 4 is a baffle.

[0063] In this technical solution, the detection sensor 5 can be a photoelectric sensor, and the sensing member 4 can be a baffle. A photoelectric sensor is installed on one chuck 2, and an infrared emitter is installed on the other chuck 2. When the winding drum 3 is installed on the chuck 2, the baffle is located between the photoelectric sensor and the infrared emitter, blocking the photoelectric sensor from receiving the infrared signal. When slippage occurs between the chuck 2 and the winding drum 3, the photoelectric sensor and the baffle are misaligned, the photoelectric sensor receives the infrared signal, and the signal fed back to the control system changes accordingly, so that the winding mechanism decelerates emergently and stops.

[0064] Embodiment 6:

[0066] The embodiments of the present application have been described above in conjunction with the accompanying drawings.
