DETAILED DESCRIPTION

[0019] The utility model will be further described below in combination with the drawings and embodiments.

[0020] Please refer to Figures 1 to 3 A metal lithium battery pole piece production equipment includes: base 1, one end of base 1 is fixedly connected with front stand 11, base 1 is installed and connected with conveying roller group 2, the other end of base 1 is fixedly connected with rear drying box 3, the position at the front of conveying roller group 2 is equipped with back frame 4, and extrusion coating head 41 is installed and connected on back frame 4;Joint adjusting mechanism, joint adjusting mechanism includes shaft 42, shaft 42 is fixedly connected with extrusion coating head 41, shaft 42 is rotatably connected with the two ends of back frame 4, one end of shaft 42 is fixedly connected with side tooth ring 43, one side of side tooth ring 43 is equipped with alignment gear 44, alignment gear 44 and side tooth ring 43 are mutually engaged, and control assembly is arranged on back frame 4.

[0021] In the specific implementation process, as Figure 1 And Figure 2 Shown, the control assembly includes rear stand 5, one end of rear stand 5 is fixedly connected with back frame 4, the other end of rear stand 5 is installed and connected with motor 51, and the output shaft of motor 51 is fixedly connected with the center position of alignment gear 44.

[0022] It should be noted that: the control assembly plays a key driving role in the whole equipment operation.Rear stand 5 is used as the installation carrier of motor 51, motor 51 selects high-precision, high-torque servo motor, and the rotating speed of output shaft can be accurately controlled;

[0023] When the angle of the extrusion coating head 41 needs to be adjusted, the motor 51 receives instructions from the control system (such as a PLC programmable logic controller, which can preset relevant parameters in the human-machine interface according to actual production needs), and its output shaft drives the positioning gear 44 to rotate. Since the positioning gear 44 is in close meshing with the side gear 43, the side gear 43 will rotate accordingly, and then the extrusion coating head 41 is driven by the shaft 42 to realize precise angle adjustment. The precise control of the motor 51 enables the extrusion coating head 41 to quickly and accurately adjust to the appropriate angle according to different pole piece materials and coating process requirements, ensuring the uniformity and accuracy of the coating.

[0024] Reference Figure 2 As shown in the drawings, the front frame 11 is fixedly connected with the I-shaped frame 6, and the I-shaped frame 6 is symmetrically provided with two sliding ports. The two ends of the back frame 4 are fixedly connected with limiting rods 61, and the two limiting rods 61 are respectively in sliding connection with the two sliding ports on the I-shaped frame 6. One end of the I-shaped frame 6 is installed and connected with an electric cylinder 62, and the output end of the electric cylinder 62 is fixedly connected with the back frame 4.

[0025] It should be noted that the limiting rod 61 slides smoothly in the sliding port, and at the same time, it can guide and limit the movement of the back frame 4, preventing it from deviating during movement;

[0026] When the horizontal position of the extrusion coating head 41 needs to be adjusted, the electric cylinder 62 receives instructions from the control system, and its telescopic rod extends or retracts. The extension and retraction of the telescopic rod drives the back frame 4 to slide along the sliding port on the I-shaped frame 6, so that the extrusion coating head 41 installed on the back frame 4 moves synchronously. In this way, the extrusion coating head 41 can accurately align with the copper foil, aluminum foil and other pole piece materials on the conveying roller group 2, ensuring the accuracy of the coating position and meeting the production needs of different specifications of pole pieces.

[0027] Reference Figure 2 and Figure 3 As shown in the drawings, the other end of the shaft 42 and the back frame 4 are provided with an observation assembly, which includes a side circle frame 7. The lower end of the side circle frame 7 is fixedly connected with the back frame 4, and the other end of the shaft 42 is fixedly connected with a circle needle head 71. The end of the circle needle head 71 is close to the inner wall of the side circle frame 7.

[0028] It should be noted that the observation component provides an intuitive way for the operator to understand the angle change of the extrusion coating head 41. When the extrusion coating head 41 is adjusted in angle, the rotation of the rotating shaft 42 drives the rotating of the ring needle head 71, the end of the ring needle head 71 is close to the inner wall of the side circle frame 7, and the movement track of the ring needle head 71 matches the curvature of the inner wall of the side circle frame 7. The operator can intuitively judge the angle change of the extrusion coating head 41 by observing the position change of the ring needle head 71 near the inner wall of the side circle frame 7. This design helps the operator to quickly and accurately understand the angle of the coating head during equipment debugging or production process, so as to make corresponding adjustment, improve the convenience of operation and the accuracy of angle adjustment.

[0029] Reference Figure 3 As shown in the figure, the inner wall of the side circle frame 7 is provided with an arc scale mark.

[0030] Reference Figure 1 And Figure 3 As shown in the figure, the ring needle head 71 is provided with a mounting ear, and the mounting ear is connected with a shooting head 8.

[0031] It should be noted that the setting of the shooting head 8 adds the function of real-time monitoring of the adjustment process to the device. The shooting head 8 can clearly shoot the relative position of the extrusion ring needle head 71 and the arc scale mark of the inner wall of the side circle frame 7, and can understand the angle of the extrusion coating head 41 in real time. This helps the operator to take corresponding adjustment measures in time, so as to ensure the coating quality and improve the production efficiency.

[0032] The working principle of the metal lithium battery pole piece production equipment provided by the utility model is as follows: the telescopic rod of the control electric cylinder 62 is extended or retracted, two limiting rods 61 on the back frame 4 are pushed to slide along the sliding port on the I-shaped frame 6, when the back frame 4 moves, the extrusion coating head 41 mounted thereon moves synchronously, so that the position adjustment of the extrusion coating head 41 in the horizontal direction is realized. This position adjustment can be adjusted according to the distance of the conveying position of the copper foil or aluminum foil on the conveying roller group 2. The motor 51 is started, and the output end drives the positioning gear 44 to rotate. Since the positioning gear 44 and the side gear 43 are meshed with each other, the side gear 43 rotates, and then drives the rotating shaft 42 to rotate, finally realizes the rotation of the extrusion coating head 41 around the rotating shaft 42, and achieves the purpose of adjusting the angle. For example, when the pole piece material or the coating process requirement changes, the angle of the extrusion coating head 41 is accurately controlled by the motor 51, the position of the coating head can be adjusted in real time according to the slight change of the pole piece material and the coating process, the uniformity and accuracy of the coating are further improved, so that the slurry can be uniformly coated on the pole piece, the quality of the pole piece is improved, and the deviation of the coating thickness can be well controlled in a small range.

[0033] During the angle adjustment of the extrusion coating head 41, the rotating shaft 42 drives the ring needle head 71 to rotate. The operator can intuitively understand the angle change of the extrusion coating head 41 by observing the position of the ring needle head 71 on the arc scale marked on the inner wall of the side ring frame 7, which helps to accurately control the angle of the extrusion coating head 41. When the extrusion coating head 41 is performing the coating operation, the shooting head 8 can shoot the coating process in real time. The operator can observe the relative position between the ring needle head 71 and the arc scale by connecting the display device (prior art) of the shooting head 8 to realize real-time control adjustment and take corresponding measures for adjustment to ensure the coating quality.

[0034] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields based on the content of the present application specification and drawings are also included in the patent protection range of the present application.
