Description

Technical Field

[0001] The present invention relates to the technical field of battery frame welding, and more specifically, to an ultrasonic welding machine for a battery frame of a new energy vehicle. Background Art

[0002] In recent years, new energy vehicles (NEVs), which rely on power batteries as their driving energy source, have seen rapid growth due to their low noise, environmentally friendly emissions, and strategic significance for the continued advancement of intelligent driving capabilities and sustainable energy development. The power battery is a key component in NEVs. Proper layout and installation of the power battery can provide better and safer power. To conserve battery installation space, existing NEVs typically install the power battery within a battery frame, which is then secured to the vehicle chassis. During production, the battery frame components are shaped and then assembled and welded. To enhance the safety of power batteries against external impacts, multiple layers of protection are often installed around the battery. However, the power battery generates significant heat during charging and dissipating, necessitating the installation of the battery frame within a multi-layered battery frame for water cooling.

[0003] Currently, ultrasonic welding is commonly used in the production of battery frames. However, existing ultrasonic welding machines require operators to manually assemble the first and second battery frames one by one onto the ultrasonic welding machine, and then manually start the ultrasonic welding process. This type of ultrasonic welding has low welding efficiency and is labor-intensive. It can also easily lead to poor assembly precision and warping of the first and second battery frames, impacting battery frame quality. Furthermore, during mass production, quality is unstable, affecting product yield. Summary of the Invention

The term " / and" in this article describes another type of association object relationship, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0048] Example 1:

[0049] according to Figure 1-Figure 22 As shown, an ultrasonic welding machine for battery frames of new energy vehicles includes an ultrasonic welding machine, a battery frame supply component, and a battery frame automatic assembly component, both of which are arranged on the ultrasonic welding machine. The ultrasonic welding machine includes a welding support base 1, a welding transfer component, and an ultrasonic welding component, both of which are arranged on the welding support base 1.

[0050] The welding transfer component includes a transfer support and a transfer power component. The transfer support is arranged on the welding support seat 1, and the transfer power component is arranged on the transfer support. The transfer support includes a transfer slide 2, a transfer slide 3, a workbench 4 and a welding seat 5. The transfer slide 2 is arranged on the support surface of the welding support seat 1, the transfer slide 3 is slidably mounted on the transfer slide 2, and the workbench 4 is horizontally fixed on the rotating slide to provide support for the ultrasonic welding operation.

[0051] The welding seat 5 is in the shape of a rectangular block, and there are two welding seats 5. The two welding seats 5 are arranged parallel to each other on the workbench 4, and are used to provide support for the first battery frame 17 transferred from the first battery frame removal part by the battery frame automatic assembly part. That is, the two sides of the transferred first battery frame 17 to be welded are placed one by one on the two welding seats 5, waiting to be welded by the ultrasonic welding head 11. It should be noted that a pressing locking part 6 is provided on the workbench 4 next to the welding seat 5, and the pressing locking part 6 is used to press the first battery frame 17 and the second battery frame 37 before welding onto the welding seat 5. The specific structure of the pressing locking part 6 is shown in the attached figure. Figure 19 .

[0052] The transfer power part includes a first motor 7, a first gear and a first rack 8.

The first gear is fixedly mounted on the rotating shaft of the first motor 7. The first rack 8 is fixedly mounted on the support surface, and the first rack 8 is parallel to the transfer slide 2. At the same time, the first gear on the side of the first rack 8 is engaged with the first gear. When the first motor 7 drives the first gear to rotate, the workbench 4 will be driven to slide and position on the transfer slide 2 through the first rack 8. This meets the battery frame assembly and welding requirements.

[0053] The ultrasonic welding part includes a pressure mechanism 9, an ultrasonic transducer 10 and an ultrasonic welding head 11. The pressure mechanism 9 is arranged on the welding support frame of the welding support seat 1, the ultrasonic transducer 10 is arranged on the pressure mechanism 9, and the ultrasonic welding head 11 is arranged on the ultrasonic transducer 10. Furthermore, the ultrasonic welding parts are provided with twelve sets, and the twelve sets of ultrasonic welding parts are distributed in two rows. The two rows of ultrasonic welding parts correspond to each other and serve the ultrasonic welding operations on both sides of the battery frame. It should be noted that there are two ultrasonic welding points 12 on each side of the battery frame. Since the welding length of each ultrasonic welding point 12 is long, three sets of ultrasonic welding parts are used for welding. The three sets of ultrasonic welding parts are staggered in a row, and the welding lines 13 on the bottom surface of the ultrasonic welding heads 11 of the three sets of ultrasonic welding parts are spliced and matched with each other to ensure the smooth flow of the cooling channel in the battery frame formed after ultrasonic welding (the battery frame is composed of the first battery frame 17 and the second battery frame 37 ultrasonically welded). A protective cover 14 is provided on the outside of the welding support frame.

[0054] The battery frame supply includes a first battery frame supply and a second battery frame supply 69.

The battery frame support plate 15 is in the shape of a rectangular plate. The battery frame support plate 15 is horizontally fixed on the ground by supporting legs, and the battery frame support plate 15 is connected flush with the supporting surface. The first storage box 16 is in the shape of a rectangular box. The box opening of the first storage box 16 is connected to the bottom surface of the battery frame support plate 15 through-hole. The first storage box 16 stores multiple stacked first battery frames 17. The limiting guide rail 18 is in the shape of a right-angled plate. The limiting guide rail 18 is vertically fixed to the battery frame support plate 15 at one end of the first storage box 16 with its right angle side. Two limiting guide rails 18 are symmetrically distributed on the battery frame support plate 15 at both ends of the first storage box 16. The first linear actuator 19 is fixedly mounted on the bottom surface of the first storage box 16. The first push plate 20 is a thick rectangular plate and is fixed horizontally on top of the first linear actuator 19 to provide support for the first battery frames 17 stacked in the first storage box 16. Alternatively, the first linear actuator 19 is a load-bearing, electrically, pneumatically, or hydraulically actuated telescopic push mechanism.

[0057] When the first linear actuator 19 is extended, the stacked first battery frames 17 will be pushed upward to a certain height through the first pushing plate 20, so that the horizontal height of the battery frame stacked on the top is higher than the battery frame support plate 15, and the top surface of the battery frame is located below the other right-angled side of the limiting guide rail 18, so that the first battery frame removal member can push the top battery frame outward.

[0058] The first battery frame preheating component includes a first preheating cover 21 and a first infrared heater 22. The first preheating cover 21 is in the shape of a rectangular groove. The notch of the first preheating cover 21 is fixedly buckled on the battery frame support plate 15 outside the first storage box 16. The first infrared heater 22 is arranged in the first preheating cover 21 to preheat the first battery frame 17 in the first storage box 16, narrow the temperature difference between the welding area and the non-welding area, reduce the shrinkage difference during cooling, reduce internal stress and warping risks, promote molecular chain movement, improve welding strength, and reduce the ultrasonic energy required for welding.

[0059] The first battery frame removal component includes a first battery frame removal power component and a first battery frame positioning component, and the first battery frame removal power component and the first battery frame positioning component are both arranged on the first battery frame storage component. The first battery frame removal power component includes a guide tube 23, a push transmission rod 24, a first push force plate 25, a worm gear, a second motor 27 and a worm 28.

The push transmission rod 24 is axially slidably embedded in the two guide tubes 23, and the first slide groove on the outer wall of the push transmission rod 24 cooperates with the first slider on the inner wall of the guide tube 23 to slide. The first push force plate 25 is horizontally fixed on one end of the push transmission rod 24, and the thickness of the first push force plate 25 is greater than the thickness of the first battery frame 17 and less than the height of the right-angle side of the limiting guide rail 18. The worm gear is fitted onto the outside of the push transmission rod 24 between the two guide tubes 23, and the internal thread of the worm gear is fitted with the external thread of the push transmission rod 24. The second motor 27 is fixedly mounted on the battery frame support plate 15, and the worm 28 is mounted on the rotating shaft of the second motor 27, and the worm 28 is meshed with the worm gear. When the second motor 27 drives the worm 28 to rotate, it will drive the worm gear to rotate. The rotating worm gear pushes the push transmission rod 24 to slide back and forth axially in the guide tube 23 through the external thread, thereby driving the first push force plate 25 to horizontally push the first battery frame 17 located at the top from the first storage box 16 to the first battery frame positioning member.

The positioning transmission through hole is in the shape of a long strip hole, and the axis of the positioning transmission through hole is parallel to the side positioning plate 29. Furthermore, there are three end positioning transmission blocks 30, and the three end positioning transmission blocks 30 are evenly spaced. The end-side positioning transmission plate 31 is connected to the bottom end surfaces of the three end-side positioning transmission blocks 30, and the end-side positioning transmission plate 31 slides and fits with the bottom surface of the battery frame support plate 15. The end-side positioning push plate 32 is in the shape of a right-angled plate, and one right-angled side of the end-side positioning push plate 32 is fixedly set on the three end-side positioning transmission blocks 30. The width of the other right-angled side of the end-side positioning push plate 32 is greater than the width of the right-angled side of the end-side positioning push plate 32, so as to guide the first battery frame 17 that is moved. Furthermore, two sets of end-side positioning transmission parts are provided, and the two sets of end-side positioning transmission parts are symmetrically distributed at both ends of the first battery frame 17 to clamp and position the two ends of the first battery frame 17. The area formed by the side positioning plate 29 and the two sets of end-side positioning parts is the first battery frame positioning area.

[0061] The end-side positioning power component includes a third motor 33, a first screw 34, and a first nut 35. The third motor 33 is fixedly mounted on the bottom surface of the battery frame support plate 15. The third motor 33 is a dual-axis motor.

The bottom end of the second storage box 36 is fixed to the workbench 4. Multiple stacked second battery frames 37 are stored in the second storage box 36. The second linear actuator is fixed to the bottom surface of the second storage box 36. The second push plate is fixed horizontally to the top of the second linear actuator and is used to push the stacked second battery frames 37 in the second storage box 36. Furthermore, the second battery storage unit is provided in four sets, arranged in two rows. Specifically, the two rows of second battery storage units provide second battery frames 37 on both sides of the first battery frame 17. The two sets of second battery storage units in each row provide second battery frames 37 for two locations 12 to be ultrasonically welded on one side of the first battery frame 17. When the second linear actuator extends, it pushes the stacked second battery frames 37 upward via the second push plate, raising the topmost second battery frame 37 above the opening of the second storage box 36. This allows the second battery frame removal member to push the topmost second battery frame 37 outward, facilitating the automatic battery frame assembly assembly to grasp and assemble it onto the first battery frame 17 for ultrasonic welding. Alternatively, two second storage boxes 36 in the same row can be connected through each other.

The second preheating cover 40 is in the shape of a rectangular slot, and the slot of the second preheating cover 40 is fixedly buckled outside the four sets of second storage boxes 36. The second infrared heater 41 is located inside the second preheating cover 40 to preheat the second battery frames 37 in the four sets of second storage boxes 36. This reduces the temperature difference between the welding area and the non-welding area, reduces differential shrinkage during cooling, reduces internal stress and warping risks, promotes molecular chain movement, improves weld strength, and reduces the ultrasonic energy required for welding.

[0065] The second battery frame removal member includes a second battery frame removal support member, a second battery frame removal power member and a second battery frame positioning member.

The two removal support seats 42 are symmetrically distributed to provide support for the first pushing member and the second pushing member.

[0066] The first pushing member includes a guide slide 43, a guide shaft 44 and a second pushing force plate 45. The guide slide 43 is horizontally fixed on the top surface of the removal support seat 42, and the two guide slides 43 correspond to the two removal support seats 42 one by one. One end of the guide shaft 44 is axially slidably embedded in the guide slide 43, and the two guide shafts 44 correspond to the two guide slides 43 one by one. One side of the second pushing force plate 45 is horizontally fixedly connected to the other end of the two guide shafts 44, and the second pushing force plate 45 is higher than the height of the second storage box 36 opening, so as to push the top second battery frame 37 outward. The first pushing member is used to push the two second battery frames 37 in a row of the second battery storage components.

[0067] The second pushing member has the same structure as the first pushing member. The second pushing member is symmetrical with the first pushing member on the removal support seat 42. The second pushing member is used to push the two second battery frames 37 in another row of the second battery storage elements.

[0068] The second battery frame removal power member includes a fourth motor, a second gear 47, a second rack and a third rack 49.
