Description

Technical Field

[0001] The present invention relates to the technical field of power battery processing, and in particular to a device and method for quickly cutting copper and aluminum soft connectors of power batteries. Background Art

[0002] At present, mainstream new energy vehicles usually use batteries as their power source. In order to avoid battery vibration and fatigue as much as possible during the life cycle of the vehicle, it is usually necessary to use soft electrical connectors made of multiple layers of copper and aluminum foil welded between battery modules.

[0003] In the processing of flexible connectors, the existing process is to cut one piece at a time, weld one piece, stamp one time, and cut another piece. The processing efficiency is low and cannot meet the production capacity requirements of customers. Therefore, it is very important to cut multiple flexible connectors at one time to complete multiple welding and stamping at one time to improve efficiency.

[0004] However, after the flexible connector is punched and formed from the metal strip, in order to achieve one-time cutting of multiple pieces, each flexible connector must be accurately cut and retain the spacing part (not cut). The spacing part can keep the cut strips connected and facilitate simultaneous cutting. The existing punching equipment cannot meet the forming requirements, so the equipment and process need to be further optimized. Summary of the invention

[0005] The purpose of the present invention is to provide a device and method for quickly unloading copper and aluminum flexible connectors of power batteries, so as to solve the problems raised in the above-mentioned background technology and meet the requirements of efficient production.

[0022] When the slitting actuator fails to cut the material strip, the force of the top pressure piece fails, and the lifting piece drives the support plate to move upward, so that the upper slitting roller is away from the lower slitting roller.

[0023] As an optional solution, the cutting actuator includes an upper cutting knife and a lower cutting knife arranged vertically, and the cut material strip passes between the upper cutting knife and the lower cutting knife.

[0049] See also Figures 1 to 3 As shown, this embodiment provides a device for quickly unloading copper and aluminum flexible connectors of power batteries, including an unwinding mechanism 1, a feeding mechanism 2, a slitting actuator 3 and a cutting actuator 4, wherein:

[0050] The unwinding mechanism 1 is used to unwind the uncut material roll into a material strip 100, and the material strip 100 passes through the feeding mechanism 2, the cutting actuator 3 and the cutting actuator 4 in sequence;

[0051] The feeding mechanism 2 is used to drive the material belt 100 to feed;

[0052] The slitting actuator 3 is used to slit the material strip 100 into a plurality of material strips 101 and form an unslit interval section 102 on the material strip 100, and the interval section 102 is connected to the end of each material strip 101;

[0053] The cutting actuator 4 is used to cut the material strip 100 into a plurality of material segments 103 , and the cutting position is located on each spacing segment 102 , so that part of the spacing segment 102 is retained at both ends of the material segment 103 .

[0054] Therefore, through the coordinated actions of the unwinding mechanism 1, the feeding mechanism 2, the slitting actuator 3 and the cutting actuator 4, the slitting width of the material strip 101, the slitting length and the unslitting length on the material strip 100 and the length of the material segment 103 can be accurately controlled to meet the forming requirements of workpieces of various sizes; in addition, by controlling the slitting actuator 3 to cut or not cut, a method of forming a spacing segment 102 on the material strip 100 allows multiple material strips 101 to be unloaded at the same time, which is convenient for subsequent processing and greatly improves the processing efficiency.

[0055] Optionally, the feeding mechanism 2 includes an upper pressure roller 21 and a lower pressure roller 22 arranged vertically, and the material belt 100 passes between the upper pressure roller 21 and the lower pressure roller 22. The lower pressure roller 22 is driven to rotate by a first driving member, and the rotation speed of the lower pressure roller 22 is adjustable to control the feeding speed of the material belt 100; the upper pressure roller 21 is driven by the second driving member 23 to approach or move away from the lower pressure roller 22 to control the feeding or stopping of the material belt 100.

[0056] The first driving member here is preferably a servo motor, which converts the feeding length of the material strip 100 into the rotation angle of the lower pressing roller 22, so as to accurately control the feeding amount of the material strip 100.

[0057] The second driving member 23 here is preferably a cylinder, which drives the upper pressing roller 21 and the lower pressing roller 22 to cooperate with each other to clamp the material belt 100, thereby forming a static friction force to drive the material belt 100 to feed.

[0058] Optionally, the slitting actuator 3 includes an upper slitting roller 31 and a lower slitting roller 32 arranged vertically, and the material strip 100 passes between the upper slitting roller 31 and the lower slitting roller 32, and the lower slitting roller 32 is driven to rotate by a third driving member 33; the upper slitting roller 31 is driven by a fourth driving member 34 to approach or move away from the lower slitting roller 32 to control whether the material strip 100 is cut or not.

[0059] The third driving member 33 here is preferably a servo motor. No matter in the slitting or non-slitting state, the lower slitting roller 32 can feed the material strip 100, and the feeding distance is controlled by the running angular velocity of the servo motor.

[0060] The fourth driving member 34 here is preferably a cylinder, which drives the upper slitting roller 31 and the lower slitting roller 32 to cooperate with each other to extrude the material strip 100 to achieve the slitting action, and by controlling the upper slitting roller 31 to move upward and downward, the un-slitting length and slitting length of the material strip 100 can be controlled.

[0061] Optionally, the upper slitting roller 31 is provided with a plurality of first protrusions 311 axially spaced apart, and the lower slitting roller 32 is provided with second protrusions 321 staggered with the first protrusions 311 , and the first protrusions 311 cooperate with the second protrusions 321 to achieve slitting action.

[0062] The staggered arrangement of the first protrusion 311 and the second protrusion 321 forms a plurality of cutting locations, thereby meeting the requirement of cutting the material strip 100 into material strips 101 of target width.

[0063] Furthermore, rubber parts 35 are respectively provided between adjacent first protrusions 311 and between adjacent second protrusions 321 , and the rubber parts 35 are used to cooperate with the corresponding first protrusions 311 or second protrusions 321 to press the material strip 101 .

[0064] The rubber part 35 here is injection molded on the upper slitting roller 31 and the lower slitting roller 32. The diameter of the rubber part 35 is slightly smaller than the outer edge of the corresponding first protrusion 311 and the second protrusion 321. The rubber part 35 and the corresponding first protrusion 311 and the second protrusion 321 are matched in a concave and convex manner to ensure the slitting effect.

[0065] Optionally, both ends of the upper slitting roller 31 are respectively provided with a vertically movable support plate 36, and the upper surface of the support plate 36 is provided with a top pressure piece 37 for pressing the support plate 36 downward and a lifting piece 38 for pulling the support plate 36 upward. When the slitting actuator 3 cuts the material strip 100, the top pressure piece 37 overcomes the force of the lifting piece 38 to drive the support plate 36 to move downward, so that the upper slitting roller 31 is close to the lower slitting roller 32; when the slitting actuator 3 does not cut the material strip 100, the force of the top pressure piece 37 fails, and the lifting piece 38 drives the support plate 36 to move upward, so that the upper slitting roller 31 is away from the lower slitting roller 32.

[0066] The pressing member 37 in this embodiment is exemplified by a cam assembly driven by a cylinder, and the lifting member 38 is exemplified by a tension spring, so as to realize the up and down movement of the upper slitting roller 31 .

[0067] Optionally, the cutting actuator 4 includes an upper cutting knife 41 and a lower cutting knife 42 arranged vertically, and the cut material strip 100 passes between the upper cutting knife 41 and the lower cutting knife 42. The upper cutting knife 41 is driven by a fifth driving member to approach or move away from the lower cutting knife 42 to control whether the material strip 100 is cut or not.

[0068] The fifth driving member here is preferably a motor that drives the crankshaft to link the upper cutting knife 41 to achieve periodic up and down movement to achieve the cutting function.

[0069] Optionally, a distance sensor 5 is provided between the unwinding mechanism 1 and the feeding mechanism 2 , and the distance sensor 5 is used to measure the sagging amount of the material strip 100 between the unwinding mechanism 1 and the feeding mechanism 2 .

[0070] The distance sensor 5 cooperates with the unwinding motor of the unwinding mechanism 1 to feed the material strip 100 at an appropriate speed, thereby preventing the unwinding speed from being too slow to cause inaccurate slitting size, and preventing the unwinding speed from being too fast to cause the material strip 100 to be entangled or piled up.

[0071] Optionally, a guide assembly 6 is provided between the slitting actuator 3 and the cutting actuator 4, and the guide assembly 6 is used to limit the material strip 100 to constrain the feeding posture of the material strip 100 after slitting to avoid deflection, thereby ensuring that the material strip 100 is perpendicular to the upper cutting knife 41 and the lower cutting knife 42 of the cutting device, thereby ensuring the cutting effect.

[0072] In addition, the equipment for rapid unloading of copper and aluminum flexible connectors for power batteries also includes a PLC control panel 7, which can input the cutting length, non-cutting length, number of cut pieces, cutting length, etc., and can control each cylinder, servo motor, etc. to meet the needs of cutting and unloading.

[0073] The specific processing process is as follows:

[0074] 1) Replace the upper slitting roller 31 and the lower slitting roller 32 of the corresponding slitting actuator 3 according to the target product width;

[0075] 2) placing the material coil (here, copper or aluminum foil coil) on the bracket of the unwinding mechanism 1 and fixing it with a chuck;

[0076] 3) Input parameters such as cutting length, added length (piece length difference), interval length (length not cut), cutting quantity (number of pieces cut on the material strip 100), and unloading length on the PLC control panel 7;

[0077] 4) driving the upper pressing roller 21 and the upper slitting roller 31 upward, and allowing the unrolled material strip 100 to pass through the distance sensor 5, the feeding mechanism 2, the slitting actuator 3, the guide assembly 6 and the cutting actuator 4 in sequence;

[0078] 5) driving the upper pressing roller 21 and the upper slitting roller 31 downward, so that the feeding mechanism 2 and the slitting actuator 3 respectively press the material belt 100;

[0079] 6) Activate the start button on the PLC control panel 7, the feeding mechanism 2 starts to convey the material strip 100 forward, and the slitting actuator 3 starts slitting, slitting the material strip 100 into material strips 101 of target width; when the slitting length is reached, the upper slitting roller 31 is controlled to be raised to achieve non-slitting; when the non-slitting length is reached, the upper slitting roller 31 is controlled to be lowered to continue slitting;

[0080] 7) After the slitting, the material strip 100 is in a state of having one section slid and one section not slid (interval section 102), and the material strip 100 is tidied and sent to the cutting actuator 4 through the guide assembly 6;

[0081] 8) When the interval section 102 of the material strip 100 reaches the cutting actuator 4, the upper cutting knife 41 is controlled to move downward, and cooperates with the lower cutting knife 42 to form a shear force to cut the material strip 100. The cutting position is preferably the middle position of the interval section 102;

[0082] 9) The material segment 103 after slitting and cutting is the target material length, see Figure 3 The two ends of the material segment 103 retain part of the spacing segment 102, the middle part of the material segment 103 is the cut material strip 101, and the cut material segment 103 falls onto the workbench behind the cutting actuator 4;

[0083] 10) The feeding mechanism 2 continues to operate, and performs the next slitting according to whether there is an increment (length difference) between each material segment 103;

[0084] 11) When the set cutting quantity is reached, the PLC control panel 7 will stop the command, all mechanisms will stop the action, and the material segments 103 will fall onto the workbench behind the cutting actuator 4 in the cutting order, waiting to be taken away for packaging.

[0085] Based on the above-mentioned device for quickly unloading copper and aluminum flexible connectors of power batteries, this embodiment also provides a method for quickly unloading copper and aluminum flexible connectors of power batteries, which includes the following steps:

[0087] Step 2: Cut the material strip 100 into a plurality of material segments 103 , and the cutting position is located on each interval segment 102 , so that part of the interval segment 102 is retained at both ends of the material segment 103 , so that multiple material strips 101 can be cut at the same time.

[0088] Therefore, the method for quickly cutting copper and aluminum flexible connectors for power batteries can quickly complete the cutting, and multiple cut strips 101 can be cut at the same time, so that the welding and stamping efficiency of the subsequent processes can be greatly improved on the original basis.

[0089] In summary, the device and method for rapid unloading of copper and aluminum flexible connectors for power batteries have the following advantages:

[0090] ① Multiple mechanisms are linked to achieve precise control of slitting width, length, unslitting length, etc., and can also enable the equipment to adapt to a variety of strips of different sizes and materials 100;
