Description

Technical Field

[0001] This utility model belongs to the field of copper and aluminum busbar processing technology, specifically relating to a feeding mechanism for a copper and aluminum busbar bending and forming machine for new energy vehicles. Background Technology

[0002] my country regards the development of new energy vehicles as a major measure to solve energy and environmental problems and achieve sustainable development. With the joint efforts of enterprises, the new energy vehicle industry has shown a good development momentum. As an important component of new energy vehicles, the fixing and connection effect of battery packs will affect the quality of new energy vehicles.

[0003] Battery connectors are typically used to fix and electrically connect battery packs. However, due to different application scenarios, various shapes and structures of copper or aluminum busbars are used in battery connectors. Since the outer insulation layer of copper and aluminum busbars is produced by extrusion, with product updates, soft materials such as PVC are now wrapped around the outer surface of copper and aluminum busbars as an insulation covering layer. However, during the bending and forming process of copper and aluminum busbars wrapped with soft PVC insulation covering layer, the soft PVC material makes the traditional bending and forming machine feeding mechanism prone to insulation layer displacement, insulation layer bulging, and material jamming during the feeding process, resulting in problems such as low feeding efficiency and low forming efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a feeding mechanism for a copper-aluminum strip bending and forming machine for new energy vehicles, which aims to solve the technical problems of existing bending and forming machine feeding mechanisms, which are prone to causing insulation layer displacement, insulation layer bulging, and material jamming, resulting in low feeding efficiency and low forming efficiency.

[0005] To achieve the above objectives, this utility model provides a feeding mechanism for a copper-aluminum strip bending and forming machine for new energy vehicles. The mechanism includes a feeding box, a servo motor mounted on the feeding box, and a lower feeding wheel assembly behind the servo motor. The lower feeding wheel assembly consists of multiple lower feeding wheels connected to the feeding box via bearings. Above the lower feeding wheel assembly is a corresponding upper feeding wheel assembly, consisting of multiple upper feeding wheels corresponding to the lower feeding wheels. The upper feeding wheels are connected to the feeding box via sliding square bearing seats. Above the upper feeding wheel assembly is a cylinder assembly located at the top of the feeding box. The cylinder assembly consists of multiple actuator cylinders corresponding to the sliding square bearing seats. Under system control, the cylinder assembly controls different actuator cylinders to drive the sliding square bearing seats at different times.

[0006] Preferably, the feeding box body is provided with reserved holes for the installation of the lower feeding wheel assembly, the upper feeding wheel assembly and the cylinder assembly.

[0007] Preferably, the servo motor is connected to the lower feed wheel assembly via a transmission gear.

[0008] Preferably, there are multiple bearings, which are fixedly installed in the feeding box. A drive shaft is provided in the middle of the bearing. One end of the drive shaft is connected to the drive gear, and the other end is fixedly connected to each lower feeding wheel by screws.

[0009] Preferably, there is a gap between each pair of the lower feeding wheels; more preferably, there is a groove in the middle of each feeding wheel.

[0010] Preferably, there are multiple sliding square bearing seats, which are movably embedded in the feeding box and respectively positioned above the lower feeding wheel. The sliding square bearing seats can move up and down under the action of the cylinder assembly. The drive shaft in the sliding square bearing seat is fixedly connected to the upper feeding wheel by screws.

[0011] Preferably, the push rod at the center of the actuator cylinder body is fixedly connected to the sliding square bearing seat, so as to control the corresponding actuator cylinder to control the up and down movement of the corresponding sliding square bearing seat.

[0012] The feeding mechanism of the copper-aluminum strip bending and forming machine for new energy vehicles provided in this embodiment of the utility model has at least one of the following technical effects: The feeding mechanism of the copper-aluminum busbar bending and forming machine for new energy vehicles in this utility model, with the cooperation of a servo motor, a lower feeding wheel group, an upper feeding wheel group, and a cylinder group, controls the upper feeding wheel group to alternately press and release the material. This not only realizes the feeding of copper-aluminum busbars, but also solves the problems of low feeding efficiency and low forming efficiency of copper-aluminum busbars with PVC insulation covering during the bending and forming process. Due to the softness of the PVC material, the feeding mechanism of the existing bending and forming machine is prone to insulation layer displacement, insulation layer bulging, and material jamming during the feeding process.

[0013] The feeding mechanism of the copper and aluminum busbar bending and forming machine for new energy vehicles in this utility model can adapt to the feeding of copper and aluminum busbars of various sizes through the cooperation of the upper feeding wheel group and the cylinder group, and has a wider range of applications.

[0014] The feeding mechanism of the copper-aluminum strip bending and forming machine for new energy vehicles in this utility model has a simple and compact structure and occupies little space during operation. The servo motor, lower feeding wheel assembly, upper feeding wheel assembly and cylinder assembly are all fixed on the feeding box, which is beneficial for the bending and forming machine to control the feeding mechanism to drive the copper-aluminum plate to rotate and change the direction of the copper-aluminum plate during the feeding process, so as to cooperate with the extrusion head to bend and form the copper-aluminum strip, and further improve the bending and forming efficiency.

[0023] In one embodiment of this utility model, such as Figure 1 , 2 As shown, a feeding mechanism for a copper-aluminum strip bending and forming machine for new energy vehicles is provided, including a feeding box 10, a servo motor 20, a lower feeding wheel set 30, an upper feeding wheel set 40, and a cylinder set 50.

[0024] The feeding box 10 has reserved holes (not shown) for installing the lower feeding wheel assembly 30, the upper feeding wheel assembly 40, and the cylinder assembly 50. A servo motor 20 is fixedly installed at one end of the feeding box 10 in the material receiving direction. The servo motor 20 is connected to the lower feeding wheel assembly 30 via a transmission gear (not shown). The lower feeding wheel assembly 30 is located behind the end of the servo motor 20 opposite to the material discharge direction. The lower feeding wheel assembly 30 consists of multiple lower feeding wheels, with a gap between every two lower feeding wheels. The multiple lower feeding wheel assemblies 30 are connected to the feeding box 10. The lower feeding wheel assembly 30 is connected to the upper feeding wheel assembly 40, which is composed of multiple upper feeding wheels corresponding to the lower feeding wheels. The upper feeding wheel assembly 40 is connected to the feeding box 10. Above the upper feeding wheel assembly 40, there is a cylinder assembly 50 located at the top of the feeding box 10. The cylinder assembly 50 is composed of multiple actuator cylinders corresponding to the upper feeding wheels. Under the control of the system, the cylinder assembly 50 controls different actuator cylinders to drive the upper feeding wheels to move up and down at different times.

[0025] The lower feeding wheel assembly 30 consists of a bearing 31, a first lower feeding wheel 32, a second lower feeding wheel 33, a third lower feeding wheel 34, and a fourth lower feeding wheel 35.

[0026] Multiple bearings 31 are fixedly installed in the feeding box 10. The bearings 31 are fixedly connected to the first lower feeding wheel 32, the second lower feeding wheel 33, the third lower feeding wheel 34, and the fourth lower feeding wheel 35 by screws. The bearings 31 serve to fix the position of the first lower feeding wheel 32, the second lower feeding wheel 33, the third lower feeding wheel 34, and the fourth lower feeding wheel 35 while allowing the first lower feeding wheel 32, the second lower feeding wheel 33, the third lower feeding wheel 34, and the fourth lower feeding wheel 35 to rotate.

[0027] The first lower feeding roller 32, the second lower feeding roller 33, the third lower feeding roller 34, and the fourth lower feeding roller 35 are arranged sequentially along the feeding box 10 toward the servo motor 20. The first lower feeding roller 32, the second lower feeding roller 33, the third lower feeding roller 34, and the fourth lower feeding roller 35 are connected to the transmission chain through a transmission shaft located at the center of the roller, so that the servo motor 20 can drive the first lower feeding roller 32, the second lower feeding roller 33, the third lower feeding roller 34, and the fourth lower feeding roller 35 to rotate. Preferably, the first lower feeding roller 32, the second lower feeding roller 33, the third lower feeding roller 34, and the fourth lower feeding roller 35 are all provided with grooves in the middle to facilitate better conveying of copper and aluminum bars.

[0028] The upper feeding wheel assembly 40 consists of a sliding square bearing seat 41, a first upper feeding wheel 42, a second upper feeding wheel 43, a third upper feeding wheel 44, and a fourth upper feeding wheel 45.

[0029] Multiple sliding square bearing seats 41 are movably embedded in the feeding box 10 and are respectively located above the first lower feeding wheel 32, the second lower feeding wheel 33, the third lower feeding wheel 34, and the fourth lower feeding wheel 35. The sliding square bearing seats 41 can move up and down under the action of the cylinder group 50. The sliding square bearing seats 41 are fixedly connected to the first upper feeding wheel 42, the second upper feeding wheel 43, the third upper feeding wheel 44, and the fourth upper feeding wheel 45 by screws. The sliding square bearing seats 41 serve to fix the position of the first upper feeding wheel 42, the second upper feeding wheel 43, the third upper feeding wheel 44, and the fourth upper feeding wheel 45, while allowing the first upper feeding wheel 42, the second upper feeding wheel 43, the third upper feeding wheel 44, and the fourth upper feeding wheel 45 to rotate under the action of the moving copper-aluminum busbar and move up and down under the drive of the cylinder group 50.

[0030] The first upper feeding roller 42, the second upper feeding roller 43, the third upper feeding roller 44, and the fourth upper feeding roller 45 are correspondingly arranged with the first lower feeding roller 32, the second lower feeding roller 33, the third lower feeding roller 34, and the fourth lower feeding roller 35. The first upper feeding roller 42, the second upper feeding roller 43, the third upper feeding roller 44, and the fourth upper feeding roller 45 cooperate with the first lower feeding roller 32, the second lower feeding roller 33, the third lower feeding roller 34, and the fourth lower feeding roller 35 to convey the copper and aluminum busbars to the extrusion head. At the same time, they also play a role in controlling the first upper feeding roller 42, the second upper feeding roller 43, the third upper feeding roller 44, and the fourth upper feeding roller 45 to rise and fall in a regular manner through the control of the cylinder group 50. This avoids the displacement, bulging, and jamming of the insulation layer during the feeding process without affecting the material conveying of the copper and aluminum busbars.

[0031] The cylinder group 50 consists of a first actuating cylinder 51, a second actuating cylinder 52, a third actuating cylinder 53, and a fourth actuating cylinder 54. The first actuating cylinder 51, the second actuating cylinder 52, the third actuating cylinder 53, and the fourth actuating cylinder 54 are fixedly mounted on the top of the feeding box 10, corresponding to the first upper feeding wheel 42, the second upper feeding wheel 43, the third upper feeding wheel 44, and the fourth upper feeding wheel 45, and are fixedly connected to the sliding square bearing seat 41 through the push rod in the center of the cylinder body. The first actuating cylinder 51, the second actuating cylinder 52, the third actuating cylinder 53, and the fourth actuating cylinder 54 play the role of controlling the up and down movement of the corresponding first upper feeding wheel 42, the second upper feeding wheel 43, the third upper feeding wheel 44, and the fourth upper feeding wheel 45.

[0032] The working principle of this utility model is as follows: When the feeding mechanism of a copper-aluminum busbar bending and forming machine for new energy vehicles starts feeding, the servo motor 20 rotates under the control of the computer, driving the lower feeding wheel group 30 to rotate clockwise. At the same time, under the control of the computer, the second upper feeding wheel 43, the third upper feeding wheel 44, and the fourth upper feeding wheel 45 move downward under the drive of the second execution cylinder 52, the third execution cylinder 53, and the fourth execution cylinder 54 above, cooperating with the second lower feeding wheel 33, the third lower feeding wheel 34, and the fourth lower feeding wheel 35 to press the copper-aluminum busbar. The first upper feeding wheel 42 is driven by the first execution cylinder 51 above, so that the first upper feeding wheel 42 is in a relaxed state without pressing the material. At this point, during the feeding section (approximately one rotation of the feeding wheel), the first upper feeding wheel 42, under computer control, is driven by the first upper actuator 51 to clamp the material. The second upper feeding wheel 43, under computer control, is driven by the second upper actuator 52 to relax, releasing the material. Now, the first upper feeding wheel 42, the third upper feeding wheel 44, and the fourth upper feeding wheel 45 are clamping the material, while the second upper feeding wheel 43 is relaxing. During the feeding section (approximately one rotation of the feeding wheel), the second upper feeding wheel 43, under computer control, is driven by the second upper actuator 52 to clamp the material. The third upper feeding wheel 44, under computer control, is driven by the third upper actuator 53 to relax, releasing the material. Now, the first upper feeding wheel 42, the second upper feeding wheel 43, and the fourth upper feeding wheel 45 are clamping the material, while the third upper feeding wheel 44 is relaxing. At this point, the feeding line is in a short section (approximately one rotation of the feed reel). Under computer control, the third upper feed reel 44 is driven by the third actuator cylinder 53 above to clamp the material. Under computer control, the fourth upper feed reel 45 is driven by the fourth actuator cylinder 54 above to relax the material. At this time, the first upper feed reel 42, the second upper feed reel 43, and the third upper feed reel 44 clamp the material, while the fourth upper feed reel 45 is relaxed. (This process is repeated twice in the original text.) The above actions complete one cycle and continue to the next. By regularly and periodically pressing and releasing the corresponding feeding rollers during feeding, the problems of insulation layer displacement, insulation layer bulging, and material jamming that are common in traditional feeding mechanisms are effectively solved. This results in low feeding efficiency and low forming efficiency.

[0033] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. For example, replacing the cylinder with a servo motor.
