Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle battery assembly, and in particular to a new energy vehicle battery module assembly robot. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and new vehicle-mounted power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. At present, for pure electric vehicles or hybrid vehicles, they are equipped with new energy battery packs for providing power to the vehicles. When producing new energy battery packs, multiple battery modules are assembled in a shell, and the modules are wired and glued.

[0003] As shown in announcement number CN109638337A, a gripping mechanism for assembling power battery modules of new energy vehicles is disclosed, which includes a top plate and a gripping mechanism. The upper end surface of the top plate is provided with a connecting plate connected to the end of the manipulator, and the lower end of the top plate is provided with a linear drive component 1 and a linear drive component 2. The two linear drive components 2 are distributed in parallel, and each linear drive component 2 is equipped with two power battery module expansion positioning components. The power battery module expansion positioning component is composed of a micro-cylinder, a guide rod, a polyurethane rubber expansion ring and its locking pin. The battery module is clamped by four guide rods and transferred to the inside of the shell.

[0004] Battery module assembly is an important part of the production of new energy battery packs. When assembling the battery module, a layer of thermal conductive gel needs to be applied to the bottom of the shell, and then the finished battery module is moved to the designated position in the shell by a robot. Finally, the wiring harness is installed and arranged. Existing robots usually use clamping rods or clamping plates as described in the above patent to clamp the arranged battery modules and then move them. However, the weight of the battery modules is relatively large. If they are clamped by rods or plates, a great clamping force is required, which can easily cause deformation of the battery module shell. In addition, the end of the robot will generate inertia when lifting and lowering, which can easily cause the battery module to fall off or offset, affecting the assembly accuracy and efficiency.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-9 A new energy vehicle battery module assembly manipulator includes an assembly robot arm 1, a fixed frame 2 is fixedly arranged at the end of the assembly robot arm 1, a bidirectional screw rod 21 is rotatably arranged in the fixed frame 2, two moving plates 23 are threadedly connected on the bidirectional screw rod 21, a moving frame 24 is fixedly arranged at the bottom of each moving plate 23, a clamping plate 25 is slidably arranged in each moving frame 24, a support plate 35 is slidably arranged at the bottom of each clamping plate 25, and two friction wheels 31 are rotatably arranged on each clamping plate 25;

[0031] The filling mechanism includes a filling tube 12 arranged in the fixed frame 2 and a sealing plate 44 slidably arranged on the clamping plate 25. The filling tube 12 is used to fill the heat insulating gel between two adjacent battery modules. The two-way screw rod 21 drives the two clamping plates 25 to move and drives the two friction wheels 31 to rotate, so that the two friction wheels 31 lift the battery module upward and insert the support plate 35 into the bottom of the battery module; the assembly robot 1 is a prior art and will not be described in detail here. The fixed frame 2 is fixedly arranged at the end of the assembly robot 1. The two-way screw rod 21 has two thread grooves with opposite thread directions. The two moving plates 23 are threadedly connected with the two thread grooves one by one. When the assembly robot 1 carries the battery When installing the battery module, the clamping plate 25 is used to clamp the battery module. In order to solve the heat dissipation problem, the existing battery pack needs to fill the gap between two adjacent battery modules with thermal conductive gel when installing the battery module. Usually, the thermal conductive gel is manually filled into the gap between the battery modules after the battery module is completely installed, which is inefficient and difficult to control the filling amount. In the initial state, the two moving plates 23 are in the middle position of the corresponding thread groove. When in use, the two clamping plates 25 are moved to the two sides of the corresponding battery module by assembling the mechanical arm 1, and the bidirectional screw rod 21 is rotated to make the two moving plates 23 move towards the direction close to the battery module at the same time. When the two clamping plates 25 are against the battery module, the two moving plates 23 are moved to the direction close to the battery module. When the battery module is connected, the two-way screw rod 21 continues to rotate. At this time, each friction wheel 31 rotates to lift the battery module slightly. When the friction wheel 31 rotates, it drives the support plate 35 to move in the direction close to the battery module. The side of the support plate 35 close to the battery module is set as an inclined surface 351. When the bottom of the battery module is lifted, the support plate 35 is inserted into the bottom of the battery module to support the battery module, so that the battery module can be kept stable when the assembly robot 1 moves, and it does not need to use a huge clamping force to ensure that the battery module will not fall or deviate. Then, the battery module is moved to the specified position inside the battery pack shell by the assembly robot 1, and then the two-way screw rod 21 is reversed. When the screw rod 21 reverses, the movable plate 23 and the movable frame 24 first move away from the battery module. At this time, the clamping plate 25 is still in contact with the battery module, and the support plate 35 is pulled out from the bottom of the battery module, and the friction wheels 31 reverse, so that the battery module is pressed downward by friction, and then the battery module is fully in contact with the thermal conductive glue coated on the inside of the shell, thereby improving the thermal conductivity efficiency of the thermal conductive glue and the connection stability between the battery module and the shell. When the movable frame 24 moves away from the battery module, it drives the sealing plate 44 to seal both sides of the gap between the two adjacent battery modules. As the movable plate 23 moves, the thermal conductive gel in the filling tube 12 is filled into the gap between the two adjacent battery modules.

[0032] Furthermore, a plurality of springs 26 are fixedly arranged between each mobile frame 24 and the corresponding clamping plate 25, a rotating shaft 36 is rotatably arranged on the clamping plate 25, a gear ring 41 is fixedly arranged on the rotating shaft 36, and a gear plate 42 for driving the gear ring 41 to rotate is fixedly arranged on the mobile frame 24; four springs 26 are fixedly arranged between each mobile frame 24 and the clamping plate 25 sliding thereon, the two friction wheels 31 on each clamping plate 25 are rotatably fixedly connected to the rotating shaft 36 arranged on the clamping plate 25, the gear ring 41 is fixedly arranged between the two friction wheels 31 on the same rotating shaft 36, and each friction wheel 31 is partially exposed from the side of the corresponding clamping plate 25 close to the battery module, and the friction wheel 31 is fixedly arranged between the two friction wheels 31 on the same rotating shaft 36. The rubbing wheel 31 has a certain elasticity. When the battery module needs to be clamped, the two moving frames 24 are driven to move toward the direction close to the battery module through the bidirectional screw rod 21. The friction wheel 31 first abuts against the battery module. As the moving frame 24 moves, the springs 26 are compressed, and the pressure of the friction wheel 31 on the battery module gradually increases. The tooth plate 42 moves with the moving frame 24. When the spring 26 is compressed a certain distance, the tooth plate 42 engages with the tooth ring 41. At this time, the movement of the moving frame 24 drives the tooth plate 42 to drive the tooth ring 41 to rotate, and then the rotating shaft 36 rotates, thereby driving the two friction wheels 31 to rotate. When the two friction wheels 31 rotate, they drive the support plate 35 to be inserted into the bottom of the battery module.

[0033] Specifically, a plurality of abutment rods 32 are fixedly provided on one side of each friction wheel 31 away from the gear ring 41, two abutment plates 33 are slidably provided on each support plate 35, and each abutment plate 33 is provided with a first avoidance groove 34; the number of abutment rods 32 on each friction wheel 31 is four, such as Figure 8 As shown, when the friction wheel 31 rotates, it drives each abutment rod 32 to rotate around the corresponding rotating shaft 36. When the abutment rod 32 rotates, it abuts against the corresponding abutment plate 33. As the friction wheel 31 rotates, the abutment rod 32 pushes the corresponding abutment rod 32 to move toward the clamping plate 25, so that the two sides of the support plate 35 extend from the clamping plate 25 and insert into the bottom of the battery module. The bottom of the battery module is supported by the support plate 35, which can effectively prevent the battery module from falling or being displaced when the end of the assembly robot arm 1 moves.

[0034] In another embodiment of the present invention: a storage box 11 is fixedly arranged in the fixed frame 2, and the filling tube 12 includes a first connecting tube 121 fixedly connected to the bottom of the storage box 11, a second connecting tube 122 is slidably arranged at the bottom of the first connecting tube 121, and a discharge head 123 is fixedly arranged at the bottom of the second connecting tube 122; when the battery module is on the support plate 35, the discharge head 123 is at the top of the side wall of the battery module, the storage box 11 is used to place the thermal conductive gel, the first connecting tube 121 and the second connecting tube 122 are connected to each other, when the support plate 35 places the battery module at the specified position, the moving frame 24 is driven by the bidirectional screw rod 21 to move away from the battery module, at this time, the thermal conductive gel in the storage box 11 is discharged from the discharge head 123 through the first connecting tube 121 and the second connecting tube 122 and flows into the gap between two adjacent battery modules.

[0035] Specifically, a blocking plate 44 is slidably provided on each clamping plate 25, and a screw 43 is threadedly connected in each rotating shaft 36. One end of each screw 43 away from the rotating shaft 36 is fixedly connected to each blocking plate 44 in a one-to-one correspondence; the side of the blocking plate 44 away from the abutting plate 33 is set to have an elastic rubber material. When the friction wheel 31 on the clamping plate 25 abuts against the battery module, the blocking plate 44 abuts against the edge of the battery module. With the movement of the mobile frame 24, the tooth plate 42 meshes with the tooth ring 41 and drives the tooth ring 41 to rotate The rotating shaft 36 rotates, and the gear ring 41 drives the rotating shaft 36 to rotate. Since the screw 43 is fixedly connected to the sealing plate 44, and the sealing plate 44 is slidably connected to the clamping plate 25, when the rotating shaft 36 drives the friction wheel 31 to press the battery module downward, the screw 43 moves in the direction away from the rotating shaft 36. At this time, the sealing plate 44 moves toward the gap between the two adjacent battery modules and seals it. At this time, the thermal conductive gel in the storage box 11 flows into the gap between the battery modules as the moving plate 23 moves, thereby completing the filling of the thermal conductive gel.

[0036] Furthermore, a servo motor 22 is fixedly arranged on the fixed frame 2, and the output end of the servo motor 22 is fixedly connected to the bidirectional screw rod 21, and an air bag 51 is fixedly arranged on the end of the bidirectional screw rod 21 away from the servo motor 22, and a connecting pipe 52 is fixedly connected between the end of the air bag 51 away from the servo motor 22 and the material storage box 11; the end of the connecting pipe 52 away from the air bag 51 is connected to the top of the material storage box 11, and the moving plate 23 away from the servo motor 22 is rotatably connected to the end of the air bag 51 close to the servo motor 22, and the forward and reverse rotation of the bidirectional screw rod 21 is controlled by the servo motor 22, thereby controlling the reciprocating movement of the moving plate 23, and a single The one-way valve 53 on the airbag 51 allows air to enter the airbag 51 but cannot flow out of the airbag. The one-way valve 53 close to the storage box 11 through the connecting pipe 52 allows air to enter the storage box 11 but cannot move from the storage box 11 to the connecting pipe 52. When the two movable plates 23 move toward the direction close to the battery module, the airbag 51 stretches, and air enters the airbag 51 at this time. When the battery module is placed, the movable plate 23 moves away from the battery module. At this time, the airbag 51 is compressed, and the air in the airbag 51 is squeezed into the storage box 11 through the connecting pipe 52, thereby increasing the pressure in the storage box 11, and then the thermal conductive gel in the storage box 11 is discharged into the gaps between the battery modules.

[0037] In another embodiment of the present invention, two limit plates 54 are fixedly provided in the fixed frame 2, a protruding rod 57 is fixedly provided on each movable plate 23, and a limit rod 56 is fixedly provided in the fixed frame 2; the two limit plates 54 are located on both sides of the fixed frame 2, and when the movable frame 24 is directly below the bidirectional screw rod 21, the protruding rod 57 is located above the corresponding movable plate 23, and the limit rod 56 is located below the bidirectional screw rod 21 and abuts against the movable plate 23, such as Fig. 9 As shown, when the bidirectional screw 21 rotates clockwise, the movable plate 23 moves to the right through the limitation of the limit rod 56, and when the bidirectional screw 21 rotates counterclockwise, the movable plate 23 moves to the left through the cooperation of the limit plate 54 and the protruding rod 57, thereby cooperating with the servo motor 22 to control the reciprocating movement of the movable plate 23. A second avoidance groove 55 is provided on each limit plate 54. When the assembly robot 1 is used to transport and assemble the battery module, the protruding rod 57 moves between the second avoidance groove 55 and the end of the limit plate 54 close to the storage box 11.

[0038] Specifically, both sides of the second connecting tube 122 are rotatably provided with downward pressing rods 14, and one end of each downward pressing rod 14 away from the second connecting tube 122 is rotatably provided with a slider 141, a fixing plate 13 is fixedly provided in the fixing frame 2, and each slider 141 is slidably connected to the fixing plate 13, and a first push rod 15 is movably provided on each slider 141, and one end of each first push rod 15 away from the second connecting tube 122 is rotatably provided with a second push rod 16, and one end of each second push rod 16 away from the first push rod 15 is rotatably connected to the inner wall of the fixing frame 2; when the battery module is transported, since it is necessary to fill the gap between the battery modules with thermal conductive gel, the first connecting tube 121 and the second connecting tube 122 are in a retracted state. When the battery module is on the support plate 35, the discharge head 123 is at the upper end of the side wall of the battery module, and only a small part of the second connecting tube 122 can be exposed in the fixing frame 2, such as Fig. 9 As shown, after the battery module is installed, the servo motor 22 drives the moving plate 23 to move to the end of the thread groove of the two-way screw rod 21 away from the second connecting tube 122, and the two-way screw rod 21 continues to rotate counterclockwise, and the moving plate 23 is driven to rotate by the end of the thread groove of the two-way screw rod 21, so that the moving frame 24 below the two-way screw rod 21 is rotated to the top of the two-way screw rod 21, and when the moving frame 24 rotates upward, it will abut against the connection between the corresponding first push rod 15 and the second push rod 16, so that the first push rod 15 and the second push rod 16 connected in a V shape are pressurized into a straight line, thereby causing the end of the first push rod 15 away from the second push rod 16 to move in the direction close to the first connecting tube 121, so that the corresponding slider 141 moves in the direction close to the first connecting tube 121, and the end of the corresponding lower pressing rod 14 away from the slider 141 moves downward, so that the second connecting tube 122 moves downward, so that the discharging head 123 moves downward a certain distance, and the clamping devices for clamping the battery module are all retracted to the fixed frame 2, at this time, the material storage box 11 is connected with the pump for coating the new energy battery shell, the first connecting pipe 121, the second connecting pipe 122, and the discharge head 123 can be used for coating the battery shell, and the material storage box 11 can be used as a buffer component. When the pump for conveying the thermal conductive glue is driven, the thermal conductive glue will first enter the material storage box 11 for buffering, thereby reducing the impact force on the discharge head 123, i.e., the glue gun head, when the conveying pump is started, which can effectively prevent the glue from splashing and increase the service life of the discharge head 123. When the battery pack shell is glued, or when the battery module needs to be installed, the servo motor 22 is controlled to make the bidirectional screw 21 rotate clockwise. At this time, the movable frame 24 falls, and the movable plate 23 abuts against the limit rod 56. Then, the servo motor 22 is controlled to rotate forward and reversely for multiple times to enable the airbag 51 to continuously inflate the storage box 11, thereby squeezing out the residual thermal conductive glue in the first connecting tube 121, the second connecting tube 122 and the discharge head 123, that is, the glue gun head, thereby achieving the effect of cleaning the discharge head 123.

[0039] Furthermore, each limit plate 54 is provided with a second avoidance groove 55; the servo motor 22 drives the movable plate 23 to move to the end of the thread groove of the bidirectional screw rod 21 away from the second connecting tube 122. At this time, the protruding rod 57 is directly below the corresponding second avoidance groove 55. When the end of the thread groove drives the movable plate 23 to rotate, the protruding rod 57 passes through the corresponding second avoidance groove 55, thereby preventing the limit plate 54 from interfering with the rotation of the movable plate 23.

[0040] Furthermore, a torsion spring 17 is fixedly arranged between one end of each second push rod 16 away from the first push rod 15 and the fixed frame 2; when the movable frame 24 squeezes the first push rod 15 and the second push rod 16, the torsion spring 17 is deformed, and when the movable frame 24 returns to the bottom of the bidirectional screw rod 21, the torsion spring 17 rebounds, so that the first push rod 15, the second push rod 16, the lower pressure rod 14, the second connecting tube 122, and the discharge head 123 return to their original positions, making it convenient for the subsequent filling of thermal conductive gel between the battery modules.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
