Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to a power battery casing processing equipment. Background Art

[0002] As the new energy industry is booming, the quality and efficiency of power battery production and manufacturing, as core components in key areas such as electric vehicles and energy storage systems, are receiving more and more attention. The welding quality of the battery shell, as an important protective structure for power batteries, is directly related to the safety, stability and service life of the battery.

[0003] In the current battery shell welding workflow, workers generally adopt a relatively basic operation method. When performing welding operations, they usually place the battery shell directly on an ordinary support platform, and then use a clamp to perform a simple clamping and fixing operation on the battery shell. The function of this clamp is relatively simple, and it can only play a role in preliminarily fixing the position of the battery shell to prevent it from having a large displacement during the welding process. However, in actual welding work, due to the complexity of the welding process and the diversity of the battery shell structure, it is often necessary to flexibly adjust the angle and height of the battery shell according to different welding requirements. However, the existing fixing method makes it difficult for workers to easily adjust the battery shell to the required different angles and heights during the welding process. In order to meet the welding requirements, workers have to frequently make large adjustments to their standing position and height.

[0004] This adjustment method has many disadvantages. On the one hand, frequent changes in one's own position and height greatly affect the efficiency of welding work, making the entire welding process cumbersome and time-consuming, resulting in a significant reduction in the practicality of the work. On the other hand, frequent changes in standing height put workers in an unstable working state, increasing the probability of workers making mistakes during operations, which can easily affect the quality of welding, and can also easily increase the probability of safety accidents such as accidental falls and collisions among welders, which can easily lead to danger. At the same time, due to frequent changes in the position and height of welders, it is easy to increase the fatigue of welders and affect the efficiency of welding. Summary of the invention

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0020] See also Figures 1 to 11 The embodiment of the present invention provides a processing device, which is used in the scenario where the battery shell is welded and fixed at different heights and positions according to different welding requirements. In this embodiment, the structure of the processing device is improved to enable it to have the advantages of being adjustable between multiple heights and multiple angles. Specifically, taking the welding of the battery shell as an example, as a preferred solution in this embodiment, the processing device is specifically a power battery shell processing device, which can support and adjust the battery shell in multiple amplitudes when welding.

[0021] See also Figures 1 to 11 The present invention provides a technical solution: a power battery shell processing device, which is used in scenarios where the battery shell is welded and fixed at different heights and positions according to different welding requirements.

[0022] A power battery housing processing device comprises an adjustment mechanism 2, a welding mechanism 3 and a rotating mechanism 4, wherein: The rotating mechanism 4 includes a fixed part fixedly connected to the welding mechanism 3 and a rotating part rotatably connected to the fixed part, and the rotating part is used to carry the workpiece to be welded; The adjustment mechanism 2 includes a positioning seat 201 and a secondary hydraulic rod 203. The surface of the positioning seat 201 is rotatably connected to a plurality of main hydraulic rods 202 via a rotating shaft, and a midpoint is formed between the plurality of main hydraulic rods 202. The fixed end of the secondary hydraulic rod 203 is fixedly connected to the midpoint. The ends of the secondary hydraulic rod 203 and the main hydraulic rod 202 that are away from the positioning seat 201 are both correspondingly provided with a universal joint 204. One end of the main hydraulic rod 202 away from the positioning seat 201 is connected to the welding mechanism 3 through a universal joint 204 , and the telescopic end of the auxiliary hydraulic rod 203 is connected to the fixed part through the universal joint 204 .

[0023] In this embodiment, the positioning plate 301 serves as the basic supporting component of the entire adjusting mechanism 2, and plays the role of connecting and positioning the main hydraulic rod 202 and the auxiliary hydraulic rod 203, providing a stable installation foundation for the entire device. The four main hydraulic rods 202 are distributed at the four corners of the top of the positioning plate 301. Through their own extension and shortening, the support distance between the positioning plate 301 and the rotating part can be adjusted to achieve the device to adjust the support height of the battery shell. At the same time, the four main hydraulic rods 202 can work together, and the extension and shortening of the main hydraulic rods 202 at different positions can achieve different angles of the rotating part. The battery shell can be tilted according to the welding requirements, which is convenient for the workers to weld and greatly improves the applicability of the device. The auxiliary hydraulic rod 203 can work in conjunction with the main hydraulic rod 202 to further enhance the stability and accuracy of the height adjustment of the support plate 405, and assist in achieving precise adjustment of the height of the battery shell. The universal joint 204 is respectively installed on the top of the main hydraulic rod 202 and the auxiliary hydraulic rod 203, which can enable the components connected thereto to rotate flexibly in different directions, thereby ensuring that the angle of the battery shell to be welded placed on the rotating part is adjusted more smoothly without being restricted by the connecting components.

[0024] The rotating part is used to place and support the battery shell. It can be rotatably connected to the top of the adjustment mechanism 2 and can be rotated and adjusted according to different welding positions of the battery shell, so that the staff can perform welding operations on multiple positions of the battery shell without changing their standing position, thereby improving the practicality of the device; Specifically, during welding, the welder's line of sight is tilted downward at an angle of thirty degrees for the best viewing angle. First, the welder's neck is kept in the most comfortable state, and the welding ash will not fall in the direction of the welder. At this time, the welder stands beside the rotating part along the direction of one of the main hydraulic rods 202, and the corresponding main hydraulic rod 202 is relatively extended, and the other three main hydraulic rods 202 are relatively retracted. At this time, the rotating part is tilted along the direction of the welder's line of sight, that is, tilted, so that the power battery shell to be welded on the rotating part is tilted. The welder welds the power battery shell to be welded on the rotating part through the welding mechanism 3. Through the action of the universal joint 204, physical interference is avoided when adjusting the angle of the rotating part. When the height needs to be adjusted, the auxiliary hydraulic rod 203 and the main hydraulic rod 202 are relatively extended or retracted at the same time, so that the height of the rotating part can be adjusted according to the needs of the welder, so that the rotating part is at the optimal welding height of the welder, avoiding the welder from bending over or tiptoeing for welding, and avoiding the welder's state due to the mismatch of welding height affecting the welding quality and welding efficiency; By rotating the rotating part, the surface of the power battery shell to be welded facing the welder can be adjusted, and the rotation adjustment can be performed according to the different welding positions of the power battery shell to be welded, so that the workers can perform welding operations in multiple directions of the power battery shell to be welded without changing their own standing positions, that is, the welding operation can be performed on all sides of the power battery shell to be welded, thereby improving the welding efficiency. In addition, since the welding position does not need to be changed, the position of the welding head during welding does not need to be adjusted significantly, which further ensures the quality of welding and improves the practicality of the device. The welding mechanism 3 can be a laser welding device, i.e. a welding laser generator, or other welding equipment, i.e. a welding rod welding device, or a welding device that uses a flame generated by the mixed combustion of a combustible gas and a combustion-supporting gas as a heat source. All of these are existing well-known technologies and are only cited here.

[0025] In this embodiment, as a preferred solution, it also includes a clamping mechanism 5, which includes a guide frame 501, a baffle 502, a cylinder 503 and a clamping plate 506. The guide frame 501 is rotatably connected to the rotating part, and the fixed end of the cylinder 503 is fixedly connected to the guide frame 501. The piston rod of the cylinder 503 is used to push the clamping plate 506 to clamp the workpiece to be welded on the rotating part. The baffle 502 is fixedly connected to the end face of the guide frame 501 by bolts. Through the action of the guide frame 501, it can play a supporting role and provide a supporting position for the cylinder 503, the baffle 502 and the clamping plate 506. Through the connection between the guide frame 501 and the rotating part, the guide frame 501 can be rotated on the rotating part to adjust its position. Through the setting of the cylinder 503, the clamping plate 506 can be pushed to extend or retract along the extension direction of the cylinder 503. By extending the piston rod of the cylinder 503, it pushes The clamping plate 506 clamps the workpiece to be welded placed on the rotating part. When the piston rod of the cylinder 503 is retracted, the clamping of the workpiece to be welded is released. The end of the cylinder 503 away from the piston rod (i.e., the end where the piston rod is extended by air intake) is provided with a pressure relief valve. The pressure relief valve is a prior art known technology and is a one-way valve with an adjustable threshold value. When the piston rod of the cylinder 503 is extended, when the air pressure in the cavity of the cylinder 503 at the end where the piston rod is extended by air intake reaches the threshold value, the pressure relief valve opens to discharge the gas. When the cylinder 503 needs to be retracted, the other end of the cylinder 503 (i.e., located on the other side of the piston rod, which is also the end where the piston rod is retracted by air intake) is inhaled. At this time, the end of the cylinder 503 at which the piston rod is extended by air intake no longer inhales air. The gas in the cavity at the end where the piston rod is extended by air intake is squeezed by the piston rod in cooperation with the cylinder 503. The pressure relief valve is opened to discharge the gas, and the piston rod of the cylinder 503 is retracted. It also includes a control component, which is used to control the retraction of the piston rod of the cylinder 503 located at the highest relative inclination point or the lowest relative inclination point of the rotary part; The control assembly includes a control module, a driver and a detection mechanism. The detection mechanism specifically includes an inclinometer or an inclination sensor. The inclination sensor is a known technology. When in use, the rotating part rotates. When it is detected that the cylinder 503 at the corresponding position on the rotating part is about to rotate to the highest relative inclination point or the lowest relative inclination point of the rotating part, a signal is sent to the control module, and the control module controls the corresponding cylinder 503 piston rod to be retracted. When the rotating part is in a horizontal state, the control module controls the driver to retract or extend the piston rod of the cylinder 503 to place or remove the power battery shell to be welded.

[0026] In this embodiment, as a preferred solution, there are at least four clamping mechanisms 5, and the four guide frames 501 are all rotatably connected to the rotating part and are arranged in a matrix. The clamping mechanism 5 also includes a guide block 505 and a two-position four-way solenoid valve 504. The surface of the guide frame 501 is slidably connected to the guide block 505 through an opened slide groove, and the clamping plate 506 is fixedly connected to the end surface of the guide block 505 away from the guide frame 501. The guide block 505 is fixedly connected to the piston rod of the cylinder 503 through bolts, and the two-position four-way solenoid valve 504 is used to control the extension or retraction of the piston rod of the cylinder 503; By setting the guide block 505, it can slide in the guide frame 501. The guide block 505 can provide auxiliary support and guidance for the installed clamping plate 506, thereby preventing the piston rod of the cylinder 503 from being skewed and damaged and affecting the service life of the piston rod. By setting the two-position four-way solenoid valve 504, the air intake of the cavity on one side of the piston rod of the cylinder 503 or the air intake of the cavity on the other side of the piston rod can be controlled, thereby controlling the extension or retraction of the piston rod of the cylinder 503.

[0027] See also Figures 9 to 11 In this embodiment, as a preferred solution, the two-position four-way solenoid valve 504 is provided with a first opening, a second opening, an exhaust port and a gas delivery port, the first opening is connected to the air inlet port when the cylinder 503 is extended, the second opening is connected to the air inlet port when the cylinder 503 is retracted, and the gas delivery port is connected to the gas source; The two-position four-way solenoid valve 504 is provided with a first state and a second state. When the two-position four-way solenoid valve 504 is in the first state, the gas delivery port is communicated with the first opening, the second opening is communicated with the exhaust port, and the piston rod of the cylinder 503 is in a relatively extended state. When the two-position four-way solenoid valve 504 is in the second state, the gas delivery port is communicated with the second opening, the second opening is not communicated with the exhaust port, and the piston rod of the cylinder 503 is in a relatively retracted state. The two-position four-way solenoid valve 504 is electrically connected to the driver. When in use, when the rotary part is in a horizontal state, the control module controls the driver to control the two-position four-way solenoid valve 504 to be in the first state or the second state, so that the piston rod of the cylinder 503 is retracted or extended, which is used to place or remove the power battery shell to be welded. When the rotary part rotates, at least four two-position four-way solenoid valves 504 are in the first state, that is, the piston rod of the cylinder 503 is in a relatively extended state, and the power battery shell to be welded on the rotary part is clamped. The detection mechanism detects that the cylinder 503 at the corresponding position on the rotary part is 3 When the rotary part is about to rotate to the highest point or the lowest point of relative inclination of the rotary part or the corresponding position of the cylinder 503 is at the highest point or the lowest point of relative inclination of the rotary part (the highest point of relative inclination is a range, that is, the center of the rotary part is the center of the circle, the position of the cylinder 503 is the circumference, and the range of 30 degrees on both sides of the cylinder 503 is the highest point of relative inclination or the corresponding lowest point of relative inclination), a signal is sent to the control module, and the control module controls the corresponding two-position four-way solenoid valve 504 to be in the second state, and the piston rod of the cylinder 503 is retracted, releasing the corresponding two cylinders. The clamping formed by the extension of the 503 piston rod, the piston rod of the cylinder 503 located at the highest point of the relative inclination is retracted, the purpose is to make the clamping plate 506 retract to form an avoidance position to avoid affecting the sight of the welder and blocking the welding area, the piston rod of the cylinder 503 located at the lowest point of the relative inclination is retracted, the purpose is to obliquely remove the thrust of the cylinder 503 located at the lowest point of the relative inclination, the cylinders 503 on both sides of the highest point of the relative inclination or the lowest point of the relative inclination push the clamping plate 506 to form a stable clamping, through the arrangement of four guide frames 501 and the corresponding four cylinders 503, the purpose is to quickly The power battery shell to be welded is positioned and clamped so that the power battery shell to be welded is at the relative center point of the rotating part. Through the setting of the control component, the piston rod of the cylinder 503 can be automatically retracted to form an avoidance position in cooperation with the two-position four-way solenoid valve 504, thereby improving the welding efficiency. When the detection mechanism detects that the corresponding cylinder 503 leaves the relative inclination highest point or the relative inclination lowest point with the rotating part, a control signal is sent to the control module. The control module controls the corresponding two-position four-way solenoid valve 504 to be in the first state through the driver, and continues to clamp the power battery shell to be welded to ensure the stability of subsequent welding; A tilt sensor may also be provided on the surface of each guide frame 501, so that after the adjustment mechanism 2 adjusts the support angle of the device for the support plate 405, the tilt sensor can monitor the tilt angle of each guide frame 501, and send out a control electrical signal when the tilt angle reaches between the highest relative tilt point or the lowest relative tilt point. Therefore, after the support angle of the support plate 405 is adjusted, the tilt sensors on the surfaces of the two guide frames 501 at the highest relative tilt point or the lowest relative tilt point can send out a control signal; A two-position five-way solenoid valve can also be used to control the extension or retraction of the cylinder 503. At this time, there is no pressure relief valve on the cylinder 503. When the cylinder 503 is in a relatively retracted state, the internal space of the cylinder 503 cannot be sealed, so that the air pressure inside the cavity of the cylinder 503 near the output end cannot be stabilized by the sealing of the cylinder 503 itself, and the piston rod of the cylinder 503 cannot be prevented from extending outward again due to its own gravity, which easily affects the operation of the welding work. Alternatively, a cylinder 503 with pressure relief valves on both sides of the piston rod and a two-position three-way solenoid valve may be used. However, since the power battery shell to be welded does not need to be clamped when retracting, there is no need to control the clamping force. The use of a pressure relief valve causes material waste and increases costs.

[0028] See also Figure 10 to Figure 11 In this embodiment, as a preferred solution, it also includes a two-position three-way solenoid valve 507 and a blowing member. The two-position three-way solenoid valve 507 is provided with a first air port, a second air port and a vent. The first air port is connected to the air delivery port, the vent is connected to the air source, and the second air port is connected to the air inlet end of the blowing member. The two-position three-way solenoid valve 507 is electrically connected to the driver, and the two-position three-way solenoid valve 507 is provided with a first state and a second state. When the two-position three-way solenoid valve 507 is in the first state, the first air port is communicated with the air vent, and the air vent is not communicated with the second air port. The gas of the air source enters the air delivery port of the two-position four-way solenoid valve 504 through the first air port for air supply. When the two-position three-way solenoid valve 507 is in the second state, the first air port is not communicated with the air vent, that is, it is in a sealed state, and the air vent is communicated with the second air port. The gas of the air source enters the blowing piece for air supply. The blowing piece is arranged on one side of the guide frame 501, and an exhaust hole is arranged on the blowing piece. The gas entering the blowing piece is blown out through the exhaust hole. At this time, the guide frame can be rotated Toward the frame 501, the exhaust hole is directed toward the power battery shell to be welded, and the gas discharged through the exhaust hole is blown to the power battery shell to be welded. The smoke generated in the welding process can be blown away by the gas ejection, so as not to affect the staff's observation of the welding position. At the same time, the welded part can be quickly cooled after welding, further improving the welding efficiency. The specific exhaust hole direction can be adjusted according to the welding process. During the welding process, the two-position three-way solenoid valve 507 is in the first state, and the gas enters the two-position four-way solenoid valve 504 through the two-position three-way solenoid valve 507, so that the piston rod of the cylinder 503 is extended to achieve the clamping effect. Through the setting of the two-position three-way solenoid valve 507, when the driver After the two-position four-way solenoid valve 504 is controlled to be in the second state, that is, five seconds after the driver controls the two-position four-way solenoid valve 504 to be in the second state, the two-position three-way solenoid valve 507 is controlled to be in the second state, that is, no gas enters or is discharged from the two-position four-way solenoid valve 504, and it is in a sealed state, so as to ensure the stability of the air pressure inside the cavity of the cylinder 503 near the output end by means of the sealing of the cylinder 503 itself, thereby preventing the piston rod of the cylinder 503 from extending outward again due to its own gravity, so as to ensure the normal operation of the welding work (according to the volume of the power battery shell to be welded, the relative size of the cylinder 503 is relatively large, and the gas pressure has a corresponding threshold value, and at the same time, due to the entry of the blowing piece, the gas entering the cylinder 5 03's gas diversion, which easily leads to unstable air pressure inside the cavity of the cylinder 503 near the output end, and the piston rod is likely to overcome the thrust of the air flow blown out by the gas source and extend outward again due to its own gravity, thereby affecting the welding work and posing certain safety hazards). By setting the two-position three-way solenoid valve 507, a certain degree of safety can be improved, and automatic control can be achieved at the same time. When the two-position four-way solenoid valve 504 is in the first state, the control module controls the driver to make the two-position three-way solenoid valve 507 in the first state, the piston rod of the cylinder 503 extends, and the blowing piece stops blowing at the same time, reducing the use of the gas source and achieving automatic control, further improving the welding efficiency and reducing the number of operating steps; By means of the rotation of the guide frame 501, the guide frame 501 drives the clamping plate 506 arranged thereon to be laid flat, which will not affect the welding operation of the staff, thereby improving the practicality of the device.
