[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] In the present utility model, it should also be noted that the directional terms such as one side, one end, the other end, top and bottom in the embodiments of the present application are only relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0022] like Figure 1 As shown, the embodiment of the present application provides a positioning and pressing mechanism with a mechanical arm, including a frame 1, a mechanical arm mechanism 2 and a pressing mechanism 3, wherein the mechanical arm mechanism 2 is arranged on one side of the frame 1, and the pressing mechanism 3 is arranged on the other side of the frame 1, and a workbench 4 is arranged on the frame 1, and a positioning component is arranged on the workbench 4;

[0023] After the battery cell is glued, the mechanical arm drives the glued battery cell to move to the positioning component, and the positioning component starts to squeeze and align the glued battery cell, and then the pressing mechanism presses the glued battery cell. In this embodiment, the frame 1 serves as the basis of the entire mechanism and provides a stable support and installation platform for other components. The design of the frame 1 needs to be able to withstand various forces of the mechanical arm and the pressing mechanism 3 during work to ensure the stable operation of the entire mechanism. The mechanical arm mechanism 2 is responsible for moving the glued battery cell from the initial position to the positioning component. Through the motion control of the mechanical arm mechanism 2, the battery cell is accurately placed on the positioning component to prepare for the next pressing operation. The speed and accuracy of battery cell positioning are improved, and the need for manual operation is reduced. The pressing mechanism 3 is used to press the glued battery cell to ensure a firm bond between the battery cell and the glue or adhesive strip. By applying pressure to the battery cell, the penetration and bonding of the glue or adhesive strip is promoted to ensure a tight bond between the battery cell and the adhesive strip. The bonding quality of the battery cell is improved, and the stability and reliability of the battery cell during use are enhanced. The positioning component is responsible for accurately extruding and aligning the battery cell to ensure that the battery cell is in the correct position during the pressing process. The positioning component is used to position and extrude the battery cell to ensure that the battery cell will not shift during the pressing process and ensure the quality of the battery cell's lamination. This improves the accuracy of the battery cell's lamination, reduces the poor lamination caused by the displacement of the battery cell's position, and improves the product yield.

[0024] Specifically, the robot arm mechanism 2 can accurately move the glued battery cell to the positioning assembly, and the positioning assembly squeezes and aligns the battery cell to ensure the correct position of the battery cell during the pressing process, effectively avoiding the poor fitting caused by the position offset of the battery cell. After the battery cell is glued, the battery cell may be offset due to the fact that the glue is not completely dry or the weight of the battery cell itself. The positioning assembly of the present application can perform secondary positioning and correction on the battery cell after gluing to ensure that the battery cell maintains the correct position during the pressing process, thereby improving the accurate position of the battery cell in the battery pack. The battery cell after gluing is pressed by the pressing mechanism 3, which ensures the strong adhesion between the battery cell and the glue or adhesive strip, and improves the sealing of the battery cell and the subsequent pressing effect. It avoids the problems of sealing and pressing effect caused by uneven sticking of the adhesive strip. To sum up, the positioning and pressing mechanism 3 of the robot arm of the present application, through key technologies such as high-precision positioning, secondary positioning correction, and pressing mechanism 3, effectively solves the problem of position offset after gluing of battery cells and the problem of uneven adhesive strip sticking in the prior art, thereby greatly improving the quality and production efficiency of battery cell products.

[0025] like Figure 3As shown, further, the positioning assembly includes several groups of finger cylinders 50, and the finger cylinders 50 are arranged on the workbench 4. When the robot arm drives the battery cell after gluing to move to the workbench 4, the finger cylinders 50 start to squeeze the glue strip and the battery cell to align the battery cell with the glue strip. In this embodiment, the finger cylinder 50 is a part of the positioning assembly, which is used to squeeze and align the battery cell and the glue strip when the robot arm moves the battery cell to the workbench 4. The finger cylinder 50 controls its opening and closing by compressed air. When the robot arm brings the battery cell to the workbench 4, the finger cylinder 50 extends, clamps the glue strip and the battery cell, and squeezes them by the force of air pressure, so that the battery cell and the glue strip fit tightly. Through the squeezing effect of the finger cylinder 50, it can be ensured that the battery cell will not shift due to weight or the glue not being dry after gluing, which improves the accurate position of the battery cell in the battery pack. The finger cylinders 50 are arranged on the workbench 4 so that they can be operated immediately when the robot arm places the battery cell on the workbench 4. The finger cylinder 50 on the workbench 4 can directly contact and operate the newly placed battery cell, achieving fast and accurate positioning. This setting enables the positioning component to respond immediately, improves the timeliness of positioning, and ensures immediate correction and alignment of the battery cell after gluing. The function of the finger cylinder 50 is to squeeze the glue strip and the battery cell so that they fit tightly. The squeezing action of the finger cylinder 50 can promote the penetration and adhesion of the glue, while ensuring uniform contact between the battery cell and the glue strip. Squeezing helps to improve the bonding quality of the battery cell, ensure the stability and reliability of the battery cell in the battery pack, and also help to improve the overall performance of the battery pack. The operation of the finger cylinder 50 ensures the alignment of the battery cell with the glue strip, which is a key step to ensure the correct placement of the battery cell. By squeezing the battery cell and the glue strip, the finger cylinder 50 helps the battery cell stay in the correct position and prevents positional displacement. The alignment operation ensures the accurate position of the battery cell in the battery pack, which is crucial to the performance of the battery pack and the safety of the battery cell.

[0026] like Figure 2As shown, further, the pressing mechanism 3 includes a moving component and a pressing plate component 30, the moving component is arranged on the frame 1, the pressing plate component 30 is connected to the movable end of the moving component, and the moving component is used to drive the pressing plate component 30 to move above the positioning component, and then drive the pressing plate component 30 to move downward to press the battery cell after the glue is applied. In this embodiment, the moving component is arranged on the frame 1, and is used to drive the pressing plate component 30 to move above the positioning component, and further drive the pressing plate component 30 to move downward to press the battery cell after the glue is applied. The moving component may include a motor, a transmission device, a guide mechanism, etc., and the precise movement of the pressing plate component 30 is achieved through the action of these components. The motor drives the transmission device, and the transmission device transmits power to the pressing plate component 30 through the guide mechanism, so that it can move to the top of the positioning component and perform the pressing operation. The use of the moving component realizes the precise positioning and control of the pressing plate component 30, ensures the high precision and high consistency of the pressing operation, and thus improves the pressing quality of the battery cell. The pressing plate assembly 30 is connected to the movable end of the moving assembly and is used to press the battery cell after the glue is applied. The pressing plate assembly 30 is usually designed as a structure that can withstand greater pressure. It is connected to the movable end of the moving assembly so that the pressing plate can move up and down under the drive of the moving assembly. When the pressing plate assembly 30 moves above the battery cell, the pressing plate assembly 30 applies pressure downward through the action of the moving assembly to press the battery cell. The design and operation of the pressing plate assembly 30 ensure that the battery cell can be pressed evenly after the glue is applied, enhance the bonding effect between the battery cell and the glue, and improve the sealing and subsequent pressing effect of the battery cell. One of the functions of the moving assembly is to move the pressing plate assembly 30 above the positioning assembly for the pressing operation. Through the precise control of the moving assembly, the pressing plate assembly 30 can be moved above the position of the positioning assembly, and the position of the pressing plate assembly 30 is aligned with the position of the battery cell, ready for the next pressing operation. This feature ensures that the pressing operation is performed at the correct time and position, and improves the accuracy and efficiency of the pressing. The moving assembly further drives the pressing plate assembly 30 to move downward to press the battery cell. Under the action of the moving assembly, the pressure plate assembly 30 moves downward, and by applying pressure to the battery cell, the penetration and bonding of the glue is promoted, thereby ensuring a firm bond between the battery cell and the adhesive strip.

[0027] like Figure 4As shown, further, the mechanical arm mechanism 2 is also provided with a lifting component 20 and an adsorption component 21, the lifting component 20 is connected to the movable end of the mechanical arm mechanism 2, and the adsorption component 21 is connected to the movable end of the lifting component 20. In this embodiment, the lifting component 20 is connected to the movable end of the mechanical arm mechanism 2, and is used to control the height of the mechanical arm. The lifting component 20 may include components such as a motor, a lead screw, and a slider. Through the drive of the motor, the action of the lead screw and the slider, the lifting and lowering of the mechanical arm can be controlled. When the motor rotates the lead screw, the slider moves accordingly, thereby changing the height of the mechanical arm. The use of the lifting component 20 enables the mechanical arm to flexibly adjust its height to adapt to the battery cells or workbenches 4 of different heights, thereby improving the adaptability and flexibility of the mechanical arm. The adsorption component 21 is connected to the movable end of the lifting component 20, and is used to adsorb the battery cell. The adsorption component 21 may include components such as an electromagnet and a suction cup. Through the on-off control of the electromagnet or the negative pressure control of the suction cup, the adsorption and release of the battery cell can be achieved. When the electromagnet is energized, a magnetic force is generated to adsorb the battery cell; when the power is off, the magnetic force disappears and the battery cell is released. The use of the adsorption assembly 21 can achieve precise grasping and placement of the battery cell, improve the accuracy and efficiency of the operation, and reduce the need for manual operation. The lifting assembly 20 and the adsorption assembly 21 are both connected to the movable end of the robot arm mechanism 2, so that they can move with the movement of the robot arm. The lifting assembly 20 and the adsorption assembly 21 are connected to the movable end of the robot arm mechanism 2 through mechanical connectors (such as pins, joints, etc.), so that they can move accordingly with the rotation, swinging and other movements of the robot arm. This feature enables the lifting assembly 20 and the adsorption assembly 21 to work in conjunction with the robot arm mechanism 2 to achieve precise positioning and operation, and improve the working efficiency and stability of the entire mechanism.

[0028] like Figure 2As shown, further, the moving assembly includes a transverse moving member 31, a longitudinal moving member 32 and a height moving member 33, the longitudinal moving member 32 is arranged on the frame 1, the transverse moving member 31 is connected to the longitudinal moving member 32, the height moving member 33 is connected to the transverse moving member 31, and the pressing plate assembly 30 is connected to the height moving member 33. In this embodiment, the longitudinal moving member 32 may include components such as a motor, a lead screw, and a slider. Through the drive of the motor, the action of the lead screw and the slider, the movement of the pressing plate assembly 30 in the longitudinal direction can be controlled. When the motor rotates the lead screw, the slider moves accordingly, thereby changing the position of the pressing plate assembly 30. The use of the longitudinal moving member 32 can realize the precise movement of the pressing plate assembly 30 in the longitudinal direction, providing accurate position guarantee for the pressing operation. The transverse moving member 31 is connected to the longitudinal moving member 32, and is used to control the movement of the pressing plate assembly 30 in the transverse direction. The transverse moving member 31 may include components such as a motor, a gear, and a track. Through the drive of the motor and the action of the gear, the transverse movement is realized on the track. The use of the lateral moving member 31 can realize the precise movement of the platen assembly 30 in the lateral direction, providing greater flexibility and accuracy for the pressing operation. The height moving member 33 is connected to the lateral moving member 31 and is used to control the movement of the platen assembly 30 in the height direction. The height moving member 33 may include components such as a motor, a lead screw, and a slider. Through the drive of the motor, the action of the lead screw and the slider, the movement of the platen assembly 30 in the height direction can be controlled. When the motor rotates the lead screw, the slider moves accordingly, thereby changing the position of the platen assembly 30. The use of the height moving member 33 can realize the precise movement of the platen assembly 30 in the height direction, providing accurate position guarantee for the pressing operation. The platen assembly 30 is connected to the height moving member 33 so that the platen assembly 30 can move with the movement of the height moving member 33. The platen assembly 30 is connected to the height moving member 33 through a mechanical connector (such as a pin, a joint, etc.), so that it can move accordingly with the movement of the height moving member 33.

[0029] like Figure 3As shown, further, the pressure plate assembly 30 includes several groups of pressure strips, and the number of the pressure strips is the same as the number of the rubber strips. In this embodiment, the pressure strips are key components in the pressure plate assembly 30, and they can be made of elastic materials with sufficient hardness and elasticity to adapt to the shape and size of the rubber strips. The design and layout of the pressure strips can be optimized according to the distribution of the rubber strips to ensure that the battery cell has a uniform pressure distribution with the rubber strips during the pressing process. The number of pressure strips is the same as the number of rubber strips, which means that each rubber strip can correspond to a pressure strip, which can ensure that the contact between the battery cell and the rubber strip is more uniform, and improve the quality and consistency of the pressing. The pressure plate assembly 30 presses the battery cell through the pressure strips. When the pressure plate assembly 30 moves above the battery cell, the pressure strips will deform according to the shape and size of the battery cell, thereby applying uniform pressure to the battery cell. This pressure helps to promote the bonding of the glue and ensure a firm bond between the battery cell and the rubber strip. Through the pressing of the pressure strips, accurate pressing of the battery cell can be achieved, the sealing of the battery cell and the subsequent pressing effect can be improved, thereby improving the quality and performance of the battery cell product. This feature ensures that every strip has its own corresponding pressure strip. By ensuring that the number of pressure strips is the same as the number of strips, it ensures that each strip has an even pressure distribution during the lamination process, thereby improving the quality and consistency of the lamination.

[0030] By adopting the above-mentioned technical solutions, the robot arm mechanism 2 of the utility model can accurately move the battery cell with glue to the positioning component, and the positioning component squeezes and aligns the battery cell to ensure the correct position of the battery cell during the pressing process, and effectively avoids the poor fitting caused by the position offset of the battery cell. After the battery cell is glued, the battery cell may be shifted due to the fact that the glue is not completely dry or the weight of the battery cell itself. The positioning component of the present application can perform secondary positioning and correction on the battery cell after gluing to ensure that the battery cell maintains the correct position during the pressing process, thereby improving the accurate position of the battery cell in the battery pack. The battery cell after gluing is pressed by the pressing mechanism 3, which ensures the strong adhesion between the battery cell and the glue or adhesive strip, and improves the sealing of the battery cell and the subsequent pressing effect. It avoids the problems of sealing and pressing effect caused by uneven sticking of the adhesive strip. To sum up, the positioning and pressing mechanism 3 of the robot arm of the present application, through key technologies such as high-precision positioning, secondary positioning correction, and pressing mechanism 3, effectively solves the problem of position offset after gluing of battery cells and the problem of uneven adhesive strip sticking in the prior art, thereby greatly improving the quality and production efficiency of battery cell products.
