Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber cloth processing, and in particular to a fixing device for connecting the carbon fiber cloth with a conductor. Background Art

[0002] Carbon fiber cloth, also known as carbon fiber cloth, is a unidirectional carbon fiber product. 1K~12K carbon fiber is transformed into carbon fiber cloth through a specific textile machine. The cloth surface is woven and locked around, and it can be used as the basic material of the double electrode plate, which is often called the electrode grid. Using carbon fiber cloth as the electrode grid can greatly reduce the total weight of the battery, and can make the electrode grid have the characteristics of high conductivity and uniform current distribution, thereby greatly improving the specific energy of the battery. Carbon fiber cloth as an electrode grid has become a development trend in battery manufacturing.

[0003] When carbon fiber cloth is used as an electrode grid, it is necessary to add a metal ear to the side of the carbon fiber cloth to connect the positive and negative electrodes. Since carbon fiber cloth is an inorganic material, its conductivity is poor and it cannot be well connected with the metal ear. There are also reports that the metal ear is connected to the carbon fiber cloth by a conductive adhesive with bonding properties. However, the electrode grid made by this method is prone to cause the ear to fall off. Therefore, it is usually necessary to fix the conductor on the carbon fiber cloth to increase the conductivity of the carbon fiber cloth, and then connect and fix the ear on the conductor to achieve a stable fixation effect; but the existing conductor fixing method mostly uses manual manual fixing of the conductor to the carbon fiber cloth one by one. The whole process is labor-intensive, resulting in low processing efficiency and poor finished product qualification rate, which is not conducive to large-scale production and processing. Summary of the invention

[0004] The object of the present invention is to provide a fixing device for connecting a carbon fiber cloth with a conductor, so as to solve the problem of low efficiency in fixing the conductor on the carbon fiber cloth in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A fixing device for connecting a carbon fiber cloth to an electrical conductor comprises a frame, a transmission mechanism is arranged on the frame, the transmission mechanism comprises a driving wheel and a driven wheel, a positioning plate is slidably connected to the frame, a first transmission rod is fixedly connected to the positioning plate, a first spring is connected between the first transmission rod and the frame, a fan gear is coaxially connected to the driving wheel, gear teeth are arranged on the first transmission rod, and the first transmission rod meshes with the fan gear through the gear teeth; a fixing plate for fixing the electrical conductor on the carbon fiber cloth is slidably connected to the frame, a first cylinder body and a second cylinder body are connected to each other, a first pressure valve is arranged between the first cylinder body and the second cylinder body, a one-way air intake valve is arranged on the first cylinder body, a second pressure valve is arranged on the second cylinder body, a first piston is slidably connected in the first cylinder body, a second spring is connected between the first piston and the first cylinder body, a first piston rod is fixedly connected to the first piston, a cam abutting against the first piston rod is coaxially connected to the driven wheel, a second piston is slidably connected in the second cylinder body, a third spring is connected between the second piston and the second cylinder body, and a second piston rod fixedly connected to the second piston and the fixing plate.

[0007] Compared with the prior art, the principles and beneficial effects of the present invention are as follows:

[0008] 1. By setting up a transmission mechanism, the carbon fiber cloth to be processed is automatically transmitted, and there is no need to manually change it every time, which improves the efficiency of the entire processing; when the transmission mechanism is transmitting, the driving wheel will drive the first transmission rod to move through the fan gear, and the first transmission rod will drive the positioning plate to approach the carbon fiber cloth, so that the positioning plate and the carbon fiber cloth are against each other and the carbon fiber cloth is pressed and fixed, and then the transmission mechanism stops transmitting, and the transmission mechanism and the positioning plate are linked through the fan gear and the first transmission rod, so that the transmission and positioning of the carbon fiber cloth are carried out at the same time, that is, when the carbon fiber cloth is transmitted to the appropriate position, the positioning plate just presses the carbon fiber cloth, which can achieve the effect of accurate positioning and improve the efficiency of the entire processing.

[0009] 2. By setting a cam, when the transmission mechanism is transmitting, the driven wheel will rotate with the driving wheel and drive the cam to rotate. Since the cam is against the first piston rod, the cam will push the first piston through the first piston rod. Every time the cam rotates one circle, the first piston will reciprocate once. When the transmission mechanism transmits the carbon fiber cloth, the first cylinder will first be filled with air, and then the first piston will compress the air in the first cylinder under the action of the cam, so that the pressure in the first cylinder increases. In the process, the positioning plate approaches the carbon fiber cloth. When the positioning plate presses the carbon fiber cloth, the pressure in the first cylinder increases to the first cylinder. When the critical value of a pressure valve is reached, the first pressure valve opens automatically, connecting the first cylinder body with the second cylinder body, and the air in the first cylinder body quickly enters the second cylinder body, and pushes the second piston to drive the second piston rod and the fixing plate to approach the carbon fiber cloth, and fix the conductor on the fixing plate on the carbon fiber cloth; the transmission mechanism is linked with the fixing plate through the cam, which improves the efficiency of the entire processing. At the same time, the driving wheel and the driven wheel are synchronized, and the process of air from the first cylinder body to the second cylinder body realizes the continuous automatic control of the transmission, positioning of the carbon fiber cloth and the fixation of the conductor, thereby improving the processing efficiency.

[0010] Furthermore, the frame is provided with a pre-positioning mechanism, which includes a pre-positioning plate slidably connected to the frame, a fourth spring is connected between the pre-positioning plate and the frame, a wedge groove is opened on the pre-positioning plate, and a wedge rod for inserting into the wedge groove is fixedly connected to the first transmission rod.

[0011] When the first transmission rod drives the positioning plate to approach the carbon fiber cloth, it will also drive the wedge rod to move. When the wedge rod moves, it will interact with the wedge groove. At this time, the pre-positioning plate will approach the carbon fiber cloth under the action of the wedge rod and the fourth spring; when the carbon fiber cloth is shifted on the transmission mechanism, the pre-positioning plates on both sides will correct its position by abutting against the carbon fiber cloth, thereby pre-positioning the carbon fiber cloth, so that the positioning plate can finally accurately position the carbon fiber cloth, thereby accurately fixing the conductor on the carbon fiber cloth.

[0012] Furthermore, the wedge rod comprises an outer sleeve rod fixed on the first transmission rod, an inner sleeve rod is slidably connected inside the outer sleeve rod, the end of the inner sleeve rod is wedge-shaped, and a fixing block is provided on the outer sleeve rod.

[0013] According to the distance between the positioning plate and the carbon fiber cloth and the width of the carbon fiber cloth, the inner sleeve rod is slidably adjusted to adjust the length of the wedge rod, thereby adjusting the distance between the pre-positioning plate and the carbon fiber cloth, so that the pre-positioning plate can correct the position of the carbon fiber cloth before the positioning plate presses the carbon fiber cloth.

[0014] Furthermore, the frame is slidably connected with a receiving plate located directly below the fixed plate, the receiving plate is fixedly connected with a second transmission rod, the second transmission rod is provided with gear teeth, and the frame is rotatably connected with a gear meshing with both the first transmission rod and the second transmission rod.

[0015] When the first transmission rod drives the positioning plate to approach the carbon fiber cloth, it will also drive the second transmission rod to move through the gear, and the second transmission rod will drive the receiving plate to approach the carbon fiber cloth. When the positioning plate presses the carbon fiber cloth, the receiving plate will also move to contact the carbon fiber cloth and provide a supporting force to the carbon fiber cloth, so that the fixing plate can fix the conductor.

[0016] Furthermore, the area of ​​the receiving plate facing the carbon fiber cloth is larger than the area of ​​the fixing plate facing the carbon fiber cloth, so that the receiving plate can provide sufficient support force to the carbon fiber cloth when the fixing plate fixes the conductor, making the fixation more stable and accurate.

[0017] Furthermore, a rubber layer is provided on the side of the positioning plate in contact with the carbon fiber cloth. The rubber layer plays a buffering role and reduces the wear on the surface of the carbon fiber cloth during the pressing process of the positioning plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The embodiment is basically as shown in the attached Figures 1 to 3 As shown:

[0024] A fixing device for connecting carbon fiber cloth and an electrical conductor comprises a frame 1, on which a transmission mechanism is provided, the transmission mechanism comprises a driving wheel 2, a driven wheel 3 and a conveyor belt 4 wound between the driving wheel 2 and the driven wheel 3, and a motor (not shown in the figure) is fixedly connected to the frame 1 for driving the driving wheel 2 to rotate. A positioning plate 5 is vertically slidably connected to the frame 1, and a rubber layer is fixedly connected to the side of the positioning plate 5 that contacts the carbon fiber cloth 29 to reduce the wear on the surface of the carbon fiber cloth caused by the positioning plate during the pressing process.

When the pressure in the first cylinder body 10 increases to a critical value of the first pressure valve 12, the first pressure valve 12 will automatically open to allow the air in the first cylinder body 10 to enter the second cylinder body 11; a one-way intake valve (not shown in the figure) is installed on the first cylinder body 10, which is connected to the outside world and the first cylinder body 10 and is unidirectional to the first cylinder body 10. A second pressure valve 13 is installed on the second cylinder body 11. When the pressure in the second cylinder body 11 increases to a critical value, the first pressure valve 12 will automatically open to allow the air in the first cylinder body 10 to enter the second cylinder body 11. When the pressure increases to the critical value of the second pressure valve 13, the second pressure valve 13 will automatically open to discharge the air in the second cylinder 11; a first piston 14 is slidably connected in the first cylinder 10, a second spring 15 is welded between the first piston 14 and the first cylinder 10, a first piston rod 16 is fixedly connected to the first piston 14, a cam 17 is coaxially connected to the driven wheel 3 and abuts against the first piston rod 16, a second piston 18 is slidably connected in the second cylinder 11, a third spring 19 is welded between the second piston 18 and the second cylinder 11, and a second piston rod 20 fixed to the fixing plate 9 is fixedly connected to the second piston 18.

[0025] The frame 1 is provided with a pre-positioning mechanism (such as Figure 2The pre-positioning mechanism includes a pre-positioning plate 21 horizontally slidably connected to the frame 1, a fourth spring 22 is welded between the pre-positioning plate 21 and the frame 1, a wedge groove 23 is formed on the pre-positioning plate 21, a wedge rod for inserting into the wedge groove 23 is fixedly connected to the first transmission rod 6, the wedge rod includes an outer sleeve rod 24 fixed to the first transmission rod 6, an inner sleeve rod 25 is slidably connected inside the outer sleeve rod 24, the end of the inner sleeve rod 25 is wedge-shaped, and a fixing block (not shown in the figure) is provided on the outer sleeve rod 24. A receiving plate 26 located directly below the fixing plate 9 is vertically slidably connected to the frame 1, the area of ​​the receiving plate 26 facing the carbon fiber cloth 29 is larger than the area of ​​the fixing plate 9 facing the carbon fiber cloth 29, so as to support the entire carbon fiber cloth 29, a second transmission rod 27 is fixedly connected to the receiving plate 26, and a gear tooth is integrally formed on the second transmission rod 27, and a gear 28 meshing with both the first transmission rod 6 and the second transmission rod 27 is rotatably connected to the frame 1.

[0026] In specific implementation, according to the distance between the positioning plate 5 and the carbon fiber cloth 29 and the width of the carbon fiber cloth 29, the inner sleeve rod 25 is slidably adjusted, and the length of the wedge rod is adjusted, thereby adjusting the distance between the pre-positioning plate 21 and the carbon fiber cloth 29, so that the pre-positioning plate 21 can correct the position of the carbon fiber cloth 29 before the positioning plate 5 is pressed against the carbon fiber cloth 29; after confirmation, the outer sleeve rod 24 and the inner sleeve rod 25 are locked using a fixed block to prevent relative sliding between the two during the movement. The carbon fiber cloth 29 to be processed is placed on the conveyor belt 4, and the motor is started. The motor will drive the driving wheel 2 to rotate in the clockwise direction, so that the conveying mechanism conveys the carbon fiber cloth 29 to the right. When the driving wheel 2 rotates, it will drive the fan gear 8 to rotate in the clockwise direction. The fan gear 8 will not mesh with the first transmission rod 6 first. At this time, the transmission mechanism will transmit the carbon fiber cloth 29 to the bottom of the positioning plate 5 and the fixing plate 9; at the same time, the driven wheel 3 will drive the cam 17 to rotate in the clockwise direction. At this time, the second spring 15 will push the first piston 14 downward, the pressure in the first cylinder body 10 will decrease, and the outside air will automatically enter the first cylinder body 10 through the one-way intake valve to achieve air replenishment.

[0027] The driving wheel 2 continues to rotate, the fan gear 8 will mesh with the first transmission rod 6, and drive the first transmission rod 6 to move downward, the first spring 7 will be stretched, and the first transmission rod 6 will drive the positioning plate 5 to move closer to the carbon fiber cloth 29; at the same time, the first transmission rod 6 will drive the second transmission rod 27 to move upward through the gear 28, and the second transmission rod 27 will drive the receiving plate 26 to move upward; the first transmission rod 6 will also drive the wedge rod to move downward, and the wedge rod will be inserted into the wedge groove 23 when it moves downward. At this time, the fourth spring 22 will push the pre-positioning plate 21 to move closer to the carbon fiber cloth 29. When the carbon fiber cloth 29 is offset on the transmission mechanism, the pre-positioning plates 21 on both sides will correct the position of the carbon fiber cloth 29 by abutting against it, thereby pre-positioning the carbon fiber cloth 29. At the same time, the cam 17 will continue to rotate and push the first piston rod 16 upward, and the first piston rod 16 will drive the first piston 14 to compress the air in the first cylinder 10, so that the pressure in the first cylinder 10 gradually increases. When the positioning plate 5 presses the carbon fiber cloth 29, the motor is turned off. At this time, the receiving plate 26 moves just to abut against the carbon fiber cloth 29 and gives the carbon fiber cloth 29 an upward supporting force, which is convenient for the fixing plate 9 to fix the conductor; at the same time, the pressure in the first cylinder body 10 reaches the critical value of the first pressure valve 12, and the first pressure valve 12 automatically opens. The air in the first cylinder body 10 will quickly enter the second cylinder body 11 and push the second piston 18 downward. The third spring 19 will be stretched, and the second piston 18 will drive the second piston rod 20 and the fixing plate 9 to approach the carbon fiber cloth 29, and fix the conductor on the fixing plate 9 on the carbon fiber cloth 29.

[0028] After the fixation is completed, the air in the first cylinder 10 continues to enter the second cylinder 11. At this time, the second piston 18 will no longer move downward, so that the pressure in the second cylinder 11 increases. When the pressure increases to the critical value of the second pressure valve 13, the second pressure valve 13 will automatically open, so that the air in the second cylinder 11 is quickly discharged, and the pressure in the second cylinder 11 decreases rapidly. The third spring 19 will restore its deformation and pull the second piston 18 to move upward and reset, so that the fixed plate 9 is separated from the carbon fiber cloth 29. Start the motor again, the motor will drive the driving wheel 2 to continue to rotate in the clockwise direction. At this time, the driving wheel 2 will drive the fan gear 8 to separate from the first transmission rod 6, the first spring 7 will restore its deformation and pull the first transmission rod 6 upward to reset, the first transmission rod 6 will drive the positioning plate 5 to move away upward and release the carbon fiber cloth 29, and the transmission mechanism will continue to transmit the carbon fiber cloth 29, transport the carbon fiber cloth 29 with the conductor fixed, and at the same time, transmit the next carbon fiber cloth 29 to be processed to the bottom of the positioning plate 5.

[0029] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention. These should also be regarded as the scope of protection of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
