[0046] Combined Figures 1 to 3 , an embodiment of the present invention is proposed. A diaphragm control device includes a mounting frame 11 and a buffer mechanism. The buffer mechanism includes a primary buffer assembly 1 and a secondary buffer assembly 2. The primary buffer assembly 1 is movably connected to the mounting frame 11, the secondary buffer assembly 2 is movably connected to the primary buffer assembly 1. The secondary buffer assembly 2 is provided with a transport roller 3 and a pressure detector 4. The pressure detector 4 is used to detect the force of the transport roller 3 in the buffer direction. Wherein, the primary buffer assembly 1 drives the secondary buffer assembly 2 to drive the transport roller 3 to move in the buffer direction, and the secondary buffer assembly 2 drives the transport roller 3 to move in the buffer direction.

[0047] Specifically, the upstream of the diaphragm control device is connected to the diaphragm unwinding device, and its downstream is connected to the laminating device. The mounting frame 11 is a vertically arranged plate. A plurality of rollers for transporting the diaphragm are arranged on the mounting frame 11. The plurality of rollers form a diaphragm transport channel, receive the diaphragm from the diaphragm unwinding device, and then transport it to the laminating station for laminating. One of the transport rollers 3 is connected to two driving mechanisms to form a two-stage driving buffer mechanism. Among them, the primary driving mechanism constitutes the primary buffer assembly 1, which drives the secondary driving mechanism and the transport roller 3 to move in the buffer direction. It can be understood that the buffer direction is the direction in which the diaphragm is away from the outlet of the transport channel. Usually, the laminating station of the diaphragm and the electrode sheet is below the diaphragm transport channel, so the buffer direction is the vertical direction. The primary driving mechanism drives the secondary driving mechanism and the transport roller 3 to move upward to achieve buffering and downward to achieve unwinding. Among them, the secondary driving mechanism drives the transport roller 3 to make fine adjustments in the buffer direction. It can be understood that the pressure detector can detect the force of the transport roller 3 in the vertical direction, and the change in the magnitude of the force can further judge the change in the tension of the diaphragm wrapped around the transport roller 3. The secondary driving mechanism drives the transport roller 3 according to the change of the pressure detector 4. If the pressure becomes smaller, it drives the transport roller 3 to press the diaphragm further. If the pressure becomes larger, it drives the transport roller 3 to retreat one step to relax the diaphragm.

[0048] In this embodiment, a diaphragm control device with a two-stage driving structure is adopted. Among them, the transport roller 3 is connected to the secondary buffer assembly 2, and the transport roller 3 and the secondary buffer assembly 2 are jointly connected to the primary buffer assembly 1. A pressure detector 4 is also provided between the transport roller 3 and the secondary buffer assembly 2. When the primary buffer assembly 1 drives the transport roller 3 to make a buffering movement, the transport roller 3 generates an acceleration so that the force exerted on the pressure detector 4 changes. According to the pressure detector 4, the primary buffer assembly 1 controls the transport roller 3 to adjust the pressure of the transport roller 3, thereby ensuring the tension of the diaphragm moving on the transport roller 3.

[0049] Combined Figures 1 to 3 , an embodiment of the present utility model is proposed. The secondary buffer assembly 2 includes:

[0050] A frame body 21, the frame body 21 is slidably connected to the primary buffer assembly 1, the transport roller 3 is rotatably connected to the frame body 21, and the pressure detector 4 is connected to the frame body 21; and

[0051] A secondary driving member 22, one end of the secondary driving member 22 is connected to the frame body 21, and the other end is connected to the primary buffer assembly 1, and is used to drive the frame body 21 to drive the transport roller 3 to move.

[0052] Specifically, the primary buffer component 1 is provided with a vertically arranged plate. The secondary driving member 22 is connected to the plate of the primary buffer component 1, and the secondary driving member 22 is provided with an output end. The frame 21 is slidably connected to the plate of the primary buffer to form a vertical sliding. The output end of the secondary driving member 22 is connected to the frame 21 to drive the frame 21 to move. The transport roller 3 is rotatably connected to the frame 21. The diaphragm bypasses and wraps around the transport roller 3 upward from one side of the frame 21 and then reaches the lamination process downward from the other side, so that the secondary driving member 22 can tension or slow down the contact of the transport roller 3 against the diaphragm in the vertical direction to adjust the tension of the diaphragm.

[0053] In this embodiment, the secondary driving member 22 drives the transport roller 3 to move relative to the primary buffer component 1 to control the tension of the transport roller 3 on the diaphragm. It can be understood that when the transport roller 3 moves upward, the tension of the diaphragm increases, and the secondary driving member 22 drives the diaphragm to move slightly downward to slow down the contact of the transport roller 3 against the diaphragm. When the transport roller 3 moves downward, the tension of the diaphragm decreases, and the secondary driving member 22 drives the diaphragm to move slightly upward to increase the tension of the transport roller 3 on the diaphragm.

[0054] Combined with Figures 1 to 3 , an embodiment of the present utility model is proposed. The secondary driving member 22 includes:

[0055] A cylinder 221, the cylinder 221 is connected to the primary buffer component 1, the output end of the cylinder 221 is connected to the frame 21, and the pressure detector 4 is connected between the cylinder 221 and the frame 21; and

[0056] A controller, the controller is pneumatically connected to the cylinder 221, and the pressure detector 4 is electrically connected to the controller.

[0057] Specifically, the cylinder 221 is vertically arranged, the cylinder 221 is connected to the plate of the primary buffer component 1, and the push rod of the cylinder 221 pushes the frame 21 upward. The push rod of the cylinder 221 is connected to the pressure detector 4, and then the pressure detector 4 is connected to the frame 21. When the push rod of the cylinder 221 pushes the frame 21, the pressure detector 4 is clamped between the push rod and the frame 21 and is subjected to the forces in two directions, namely the thrust of the cylinder 221 and the gravity of the frame 21 plus the transport roller 3, so as to judge the tension of the transport roller 3 on the diaphragm.

[0058] Further, the controller includes a series of pneumatic components, which are connected to the cylinder 221 through an air pipe. By adjusting the air pressure driving the cylinder 221, the thrust of the cylinder 221 on the frame 21 and the transport roller 3 is adjusted, so as to adjust the tension of the transport roller 3 on the diaphragm.

[0059] In this embodiment, according to the value of the pressure detector 4, when the pressure detected by the pressure detector 4 is too high, the air pressure is reduced to reduce the thrust of the cylinder 221. When the pressure detected by the pressure detector 4 is too low, the air pressure is increased to increase the thrust of the cylinder 221. Based on the data obtained by the pressure detector 4, by dynamically maintaining the magnitude of the pressure, it is ensured that the tension of the transport roller 3 on the diaphragm remains dynamically unchanged.

[0060] Combined with Figures 1 to 3 , an embodiment of the present utility model is proposed. The secondary driving member 22 further includes an abutting block 222. One end of the abutting block 222 is connected to the pressure detector 4. An abutting surface is provided at the end of the abutting block 222 away from the pressure detector 4, and the abutting surface abuts against the frame 21.

[0061] Specifically, the cylinder 221 is vertically arranged. The cylinder 221 is connected to the plate of the primary buffer assembly 1. The push rod of the cylinder 221 pushes the frame 21 upward. The push rod of the cylinder 221 is connected to the pressure detector 4, and then the pressure detector 4 is connected to the abutting block 222. The abutting block 222 is provided with a groove or a shoulder, and abuts against the frame 21 in an abutting manner.

[0062] Optionally, abutting bumps are provided between the abutting block 222 and the frame 21, so that the abutting area between the two is more concentrated.

[0063] In this embodiment, the cylinder 221, the pressure detector 4 and the abutting block 222 are connected to the frame 21 by abutting rather than fixed connection, so as to reduce the influence of other forces. For example, if the frame 21 and the pressure detector 4 are connected by screws, the thread engagement will generate non-numerical-direction forces, which will then prevent the frame 21 from sliding, affecting the detection of the gravity of the frame 21 and the transport roller 3 by the pressure detector 4. And as the screws loosen, the force will gradually change, resulting in inaccurate testing. Then, the abutting method is used to reduce the interference of other forces.

[0064] Combined with Figures 1 to 3 , an embodiment of the present utility model is proposed. The frame 21 includes:

[0065] A first guide rail, which is connected to the primary buffer assembly 1;

[0066] A first slider, which is slidably connected to the first guide rail, and the frame 21 is connected to the first slider; and

[0067] A connecting plate, which is connected to the first slider. Bearings are provided on both sides of the connecting plate, and the transport roller 3 is arranged in the bearings.

[0068] Specifically, the connecting plate includes a horizontally arranged cross beam and mounting plates connected to both sides of the cross beam. The mounting plates are provided with structures for mounting bearings, and the bearings on both sides cooperate with the roller shafts of two of the conveying rollers 3 so that the conveying rollers 3 are rotatably connected to the connecting plate. Each mounting plate is connected to a first slider, and the first buffer assembly 1 is vertically provided with a first slide rail. The sliding fit between the first slider and the first slide rail enables the frame 21 to be slidably connected to the first buffer assembly 1.

[0069] In this embodiment, the pressure detector 4 abuts against the middle position of the cross beam with the abutting block 222, that is, to ensure as much as possible that the center of gravity of the frame 21 and the conveying rollers 3 is located vertically above the pressure detector 4. So that the pressure detector 4 can detect the pressure of the frame 21 and the conveying rollers 3, and, according to the value of the pressure detector 4, adjust the thrust of the air cylinder 221, and cooperate with the first slide rail and the first slider to enable the conveying rollers 3 to slide relative to the first buffer assembly 1.

[0070] Combined Figures 1 to 3 , an embodiment of the present utility model is proposed, and the first buffer assembly 1 includes:

[0071] A bearing plate 12, the bearing plate 12 is slidably connected to the mounting frame 11, and the second buffer assembly 2 is connected to the bearing plate 12; and

[0072] A first driving member 13, the first driving member 13 is connected to the mounting frame 11, and the first driving member 13 drives the bearing plate 12 to move.

[0073] Specifically, the bearing plate 12 is vertically arranged. A first bearing portion for bearing the second buffer assembly 2 is concavely provided on one side of the bearing plate 12, and two first guide rails are arranged at intervals on the bearing portion. The lower side of the first bearing portion is used for mounting the air cylinder 221. A second bearing portion for connecting the first driving member 13 is concavely provided on the side of the bearing plate 12 opposite to the bearing portion. It can be understood that the bearing plate 12 has a certain thickness. By concavely providing the first bearing portion and the second bearing portion on both sides of the bearing plate 12, the first driving member 13 and the second driving member 22 of the second buffer assembly 2 are respectively installed, so that the gravity of the first driving member 13, the second driving member 22 and the conveying rollers 3 is as close as possible. If the distance is too far, torque will be generated, affecting the effect of controlling the conveying rollers 3.

[0074] Optionally, the pressure detector 4 can be connected between the bearing plate 12 and the frame 21, and can also detect the pressure to adjust the tension of the diaphragm by the conveying rollers 3.

[0075] In this embodiment, the first driving member 13 drives the bearing plate 12 to move up and down to drive the second buffer assembly 2 and the conveying rollers 3 to move up and down. To achieve the function of buffering the diaphragm by the conveying rollers 3. And the second driving member 22 further drives the conveying rollers 3 to move up and down finely during the driving process of the first driving member 13 to achieve the adjustment of the tension of the diaphragm by the conveying rollers 3.

[0076] Combined with Figures 1 to 3 , an embodiment of the present utility model is proposed. The primary drive member 13 includes:

[0077] A lead screw 133, which is connected to the mounting frame 11;

[0078] A lead screw slider 134, which is slidably connected to the lead screw 133, and the carrier plate 12 is connected to the lead screw slider 134; and

[0080] Specifically, a second guide rail 131 is provided on the mounting frame 11, and a second slider 132 is provided on the carrier plate 12. The second guide rail 131 and the second slider 132 cooperate to enable the carrier plate 12 to be slidably connected in the vertical direction of the mounting frame 11. A lead screw 133 parallel to the second guide rail 131 is provided on the mounting frame 11. A lead screw slider 134 is slidably connected to the lead screw 133, and the carrier plate 12 is connected to the lead screw slider 134. The motor 135 is connected to one end of the lead screw 133 or is connected to one end of the lead screw 133 through a belt drive assembly.

[0081] Through this embodiment, the motor 135 drives the lead screw 133 to rotate, thereby driving the carrier plate 12 together with the secondary buffer assembly 2 and the transport roller 3 to move in the vertical direction.

[0082] Combined with Figures 1 to 3 , an embodiment of the present utility model is proposed. The transport roller 3 includes:

[0083] A tension roller 31, which is connected to the secondary buffer assembly 2; and
