Abstract
Description
Technical Field
[0001] This invention belongs to the field of robotic arm technology, and in particular relates to a robotic arm for assembling batteries for new energy vehicles. Background Technology
[0002] In the automated assembly process of new energy vehicle battery packs, the precise gripping of battery cells is one of the key steps, which is currently generally achieved by robotic arms. For example, announcement number CN117773999B discloses a robotic arm for assembling new energy vehicle batteries.
[0003] However, during production and transportation, battery cells easily attract dust, metal shavings, and other impurities. Especially in workshop environments after processes such as electrode cutting and casing grinding, the dust concentration is high. When the robotic gripper contacts the battery cell surface, these impurities form a "slipping layer," causing a significant decrease in the coefficient of friction (e.g., from 0.5 in the dry state to below 0.3). This leads to frequent slippage and displacement during gripping, affecting assembly efficiency (e.g., a single failed gripping requires 5-10 seconds of retry) and potentially causing scratches on the battery cell surface or damage to the electrode tabs due to multiple adjustments, affecting subsequent welding quality (e.g., increasing the rate of incomplete welds by 15%). In addition, the large temperature difference between the low-temperature workshop environment (winter room temperature <10℃) and the battery cell temperature (storage temperature 25℃) causes condensation to easily form when the robotic gripper contacts the battery cell, further reducing the coefficient of friction (the wet coefficient of friction can be as low as 0.2), making it difficult to achieve rapid and accurate positioning of the battery cell. In severe cases, fluctuations in gripping force may cause the battery cell to fall, leading to safety accidents or equipment damage.
[0004] To address this, a robotic arm for assembling batteries in new energy vehicles is proposed. Summary of the Invention

An adaptive adjustment mechanism is disposed on the side wall of the blowing mechanism, and the adaptive adjustment mechanism can adjust the blowing intensity of the blowing mechanism; A temperature sensor is fixedly mounted on the side wall of one of the clamping arms, and the temperature sensor is used to detect the surface temperature of the clamping arm; The PLC controller is fixedly embedded in the side wall of the rotating base. The rotating base, the robotic arm, the two clamping arms, the suction and dust removal mechanism, the gas heating mechanism, the air blowing mechanism, and the adaptive adjustment mechanism are all electrically connected to the PLC controller.
[0007] Preferably, the suction and dust removal mechanism includes a hollow suction plate fixedly installed on the top of the rotating base. A plurality of evenly distributed suction holes are opened on one side of the hollow suction plate, and a suction hood is fixedly installed on the other side of the hollow suction plate. A suction fan is fixedly installed inside the suction hood, and a corrugated air outlet pipe is fixedly installed on the side wall of the suction hood. An activated carbon filter screen is vertically inserted inside the hollow suction plate.
[0008] Preferably, the hollow air intake plate has an installation opening at the top, and a sealing plate is provided inside the installation opening. The lower surface of the sealing plate is fixedly connected to the top of the activated carbon filter screen, and the sealing plate and the hollow air intake plate are fixedly connected by bolts.
[0009] Preferably, the gas heating mechanism includes a fixing ring fixedly disposed inside the suction hood, and the fixing ring is located on the air inlet side of the suction fan, and multiple heating tubes are fixedly disposed inside the fixing ring.
[0010] Preferably, the blowing mechanism includes a hollow blowing plate fixedly disposed on the outside of the robotic arm, the end of the corrugated air outlet pipe away from the air suction hood is fixedly connected to the side wall of the hollow blowing plate, a plurality of evenly distributed blowing holes are arranged around the side of the hollow blowing plate away from the corrugated air outlet pipe, and a gas sealing mechanism is provided inside the hollow blowing plate.
[0011] Preferably, the gas sealing mechanism includes a movable ring disposed inside the hollow air blowing plate. Two telescopic rods are symmetrically fixed between the side wall of the movable ring and the inner side wall of the hollow air blowing plate. Each of the two telescopic rods is fitted with a first spring, and the two ends of the first spring are respectively fixedly connected to the side wall of the movable ring and the side wall of the hollow air blowing plate. Two permanent magnet blocks are symmetrically fixed on the side wall of the movable ring, and two electromagnetic blocks are symmetrically fixed on the inner side wall of the hollow air blowing plate. The positions of the electromagnetic blocks correspond to the positions of the permanent magnet blocks. Multiple evenly distributed frustum-shaped sealing heads are fixedly arranged around the side wall of the movable ring, and the multiple frustum-shaped sealing heads are distributed in a one-to-one correspondence with the multiple air blowing holes.
[0012] Preferably, the adaptive adjustment mechanism includes an adjustment housing fixedly disposed on the side wall of the hollow air blowing plate. A resistance rod is vertically fixed inside the adjustment housing. A conductive ring is slidably disposed on the rod wall of the resistance rod. An insulating slider is fixedly disposed on the outer wall of the conductive ring. The insulating slider is slidably connected to the adjustment housing. A second spring is fixedly disposed between the top of the insulating slider and the inner side wall of the adjustment housing. A pull rope is fixedly disposed at the bottom of the insulating slider.

[0013] Preferably, the inner wall of the adjusting housing is rotatably provided with a guide roller, and the pull rope passes around the outer wall of the guide roller and extends outward.
[0014] Compared with existing technologies, the advantages of this invention are as follows: The suction and dust removal mechanism, with its hollow suction plate and activated carbon filter, effectively captures dust particles and metal debris in the air. The purified gas is then blown directionally onto the clamping arm and the surface of the battery cell through the blowing mechanism. The airflow impact force removes the adsorbed dust, preventing the formation of a "slipping layer," maintaining an effective coefficient of friction between the clamping arm and the battery cell, significantly reducing the slippage rate, and improving clamping stability and assembly accuracy.
[0015] With the gas heating mechanism and temperature difference optical fiber, it automatically starts in low-temperature environments (room temperature <10℃). The heating tube heats the inhaled gas to room temperature of 25℃, reducing the temperature difference between the clamping arm and the battery cell, preventing condensation from forming during contact, maintaining surface dryness, ensuring stable friction coefficient, and achieving rapid and accurate clamping in low-temperature environments. This avoids the risk of gripping failure due to a decrease in the friction coefficient under wet conditions.
[0016] Through the adaptive adjustment mechanism, the clamping arm angle is linked with the resistance rod to monitor the cell size in real time and automatically adjust the blowing intensity. For large-sized cells: the clamping arm angle is large, the pulling rope tension is reduced, the resistance is lowered, the current is increased, the magnetic force of the electromagnet is enhanced, and the moving ring drives the frustum-shaped sealing head to increase the gap of the blowing holes, increasing the air volume and ensuring thorough dust removal. For small-sized cells: the reverse adjustment reduces the air volume to avoid excessive airflow causing cell displacement, improving the system's flexible adaptability to cells of different specifications and ensuring cleaning effect and assembly safety.

Detailed Implementation
[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0020] like Figures 1-5 As shown, a robotic arm for assembling batteries for new energy vehicles includes a rotating base 1, a robotic arm 2, and two gripping arms 3. The robotic arm 2 is fixedly mounted on the top of the rotating base 1, and the two gripping arms 3 are both located at the ends of the robotic arm 2. When the rotating base 1 rotates, it can drive the robotic arm 2 and the two gripping arms 3 at the ends to rotate at an angle, thereby completing the assembly operation of the battery cells. The robotic arm 2 also includes: The suction and dust removal mechanism 4 is located on the top of the rotating base 1 and is used to treat the dust around the robotic arm 2. The suction and dust removal mechanism 4 includes a hollow suction plate 41 fixedly mounted on the top of the rotating base 1. Multiple evenly distributed suction holes 42 are opened on one side of the hollow suction plate 41, and a suction hood 43 is fixedly mounted on the other side. A suction fan 44 is fixedly mounted inside the suction hood 43, and a corrugated exhaust pipe 45 is fixedly mounted on the side wall of the suction hood 43. An activated carbon filter 46 is vertically inserted into the hollow suction plate 41. (The corrugated exhaust pipe 45 designed here can freely extend and retract according to the operation of the robotic arm 2 without entanglement. Simultaneously, because the robotic arm 2 is mounted on the rotating base 1 at its bottom, it can achieve circumferential rotation. Therefore, during assembly, the robotic arm 2 does not need to rotate at a large angle in the vertical direction.) (The exhaust pipe 45 will not be subjected to significant pulling.) When the suction fan 44 is running, it continuously draws the gas inside the hollow suction plate 41 into the suction hood 43, creating a negative pressure environment inside the hollow suction plate 41. External air is drawn in through multiple suction holes 42 facing the robotic arm 2, thus cleaning the environment around the robotic arm 2. The air drawn into the hollow suction plate 41 is processed by the activated carbon filter 46. The top of the hollow suction plate 41 has an installation port, and the inside of the installation port has a sealing plate 47. The lower surface of the sealing plate 47 is fixedly connected to the top of the activated carbon filter 46. The sealing plate 47 and the hollow suction plate 41 are fixedly connected by bolts. When the activated carbon filter 46 needs to be replaced, the operator uses a wrench to loosen the bolts and remove the sealing plate 47 from the top of the hollow suction plate 41. At the same time, the activated carbon filter 46 is pulled out from the inside of the hollow suction plate 41 for cleaning.
[0021] The gas heating mechanism 5 is located inside the suction dust removal mechanism 4 and is used to adjust the temperature of the gas drawn in by the suction dust removal mechanism 4. The gas heating mechanism 5 includes a fixing ring 51 fixedly installed inside the suction hood 43 and the fixing ring 51 is located on the air inlet side of the suction fan 44. Multiple heating tubes 52 are fixedly installed inside the fixing ring 51. When the power supply of the heating tubes 52 is turned on, the heating tubes 52 heat the gas drawn into the suction hood 43 and raise the gas temperature to room temperature.
[0022] An air blowing mechanism 6 is installed on the outer wall of the end of the robotic arm 2 and is connected to the suction and dust removal mechanism 4. The air blowing mechanism 6 is used to blow air onto the surfaces of the two clamping arms 3 and the surface of the battery cell. The air blowing mechanism 6 includes a hollow air blowing plate 61 fixedly installed on the outside of the robotic arm 2. One end of the corrugated air outlet pipe 45 away from the suction hood 43 is fixedly connected to the side wall of the hollow air blowing plate 61. Multiple evenly distributed air blowing holes 62 are opened around the side of the hollow air blowing plate 61 away from the corrugated air outlet pipe 45. A gas sealing mechanism 63 is provided inside the hollow air blowing plate 61. The gas sealing mechanism 63 includes a moving ring 631 installed inside the hollow air blowing plate 61. Two telescopic rods 632 are symmetrically fixed between the side wall of the moving ring 631 and the inner side wall of the hollow air blowing plate 61. The rod walls of the two telescopic rods 632 are each sleeved with a first A spring 633 is provided, and the two ends of the first spring 633 are fixedly connected to the side wall of the moving ring 631 and the side wall of the hollow air blowing plate 61, respectively. Two permanent magnet blocks 634 are symmetrically fixed on the side wall of the moving ring 631, and two electromagnetic blocks 635 are symmetrically fixed on the inner side wall of the hollow air blowing plate 61. The positions of the electromagnetic blocks 635 correspond to the positions of the permanent magnet blocks 634. Multiple evenly distributed frustum-shaped sealing heads 636 are fixedly arranged around the side wall of the moving ring 631. The multiple frustum-shaped sealing heads 636 are distributed one-to-one with the multiple air blowing holes 62. By changing the current to the electromagnetic blocks 635, the electromagnetic blocks 635 generate different magnetic attraction forces on the permanent magnet blocks 634, thereby adjusting the gap between the frustum-shaped sealing heads 636 on the moving ring 631 and the air blowing holes 62, and changing the amount of gas blown out.
[0023] An adaptive adjustment mechanism 7 is disposed on the side wall of the blowing mechanism 6, and the adaptive adjustment mechanism 7 can adjust the blowing intensity of the blowing mechanism 6. The adaptive adjustment mechanism 7 includes an adjustment housing 71 fixedly disposed on the side wall of the hollow blowing plate 61. A resistance rod 72 is vertically fixed inside the adjustment housing 71. A conductive ring 73 is slidably disposed on the rod wall of the resistance rod 72. An insulating slider 74 is fixedly disposed on the outer wall of the conductive ring 73, and the insulating slider 74 is slidably connected to the adjustment housing 71. A second spring 75 is fixedly disposed between the top of the insulating slider 74 and the inner side wall of the adjustment housing 71, and a pull rope 76 is fixedly disposed at the bottom of the insulating slider 74. The pull rope 76 extends away from the insulating slider 74 to the outside of the adjustment housing 71 and is fixedly connected to the side wall of one of the clamping arms 3. A guide roller 77 is rotatably disposed on the inner side wall of the adjustment housing 71. The pull rope 76 passes around the outer wall of the guide roller 77 and extends outward. 7. The pulling direction of the pull rope 76 can be changed to reduce bending wear. When the clamping arm 3 completes the clamping of the battery cell, it will open to different degrees. The external force on the pull rope 76 is different when the clamping arm 3 opens to different degrees, so that the end of the pull rope 76 pulls the insulating slider 74 to different degrees. This makes the distance that the conductive ring 73 moves on the resistor rod 72 different, thus changing the resistance value of the resistor rod 72 connected in the circuit. The larger the opening angle of the clamping arm 3, the looser the pull rope 76 becomes as the clamping arm 3 expands outward, and the smaller the downward pulling force on the insulating slider 74. The insulating slider 74 moves upward a greater distance under the elastic force of the second spring 75, and the resistance value of the resistor rod 72 connected in the circuit decreases. The smaller the opening angle of the clamping arm 3, the greater the pulling force on the pull rope 76, the greater the downward pulling distance of the insulating slider 74, and the greater the resistance value of the resistor rod 72 connected in the circuit. According to the change of this electrical signal, the current to the solenoid block 635 is adjusted accordingly.
[0024] Temperature sensor 8 is fixedly installed on the side wall of one of the clamping arms 3, and temperature sensor 8 is used to detect the surface temperature of clamping arm 3. Temperature sensor 8 monitors the surface temperature of clamping arm 3 in real time.
[0025] The PLC controller 9 is fixedly embedded in the side wall of the rotating base 1. The rotating base 1, the robotic arm 2, the two clamping arms 3, the suction and dust removal mechanism 4, the gas heating mechanism 5, the blowing mechanism 6, and the adaptive adjustment mechanism 7 are all electrically connected to the PLC controller 9.
[0026] The operating principle of this invention is described as follows: First, the operator securely installs the rotating base 1 next to the new energy vehicle battery assembly process, connects the power supply to the robotic arm, and starts the robotic arm 2 and gripper arm 3 to perform the battery cell clamping and assembly task. During this process, the power supply to the suction fan 44 is simultaneously turned on. When the suction fan 44 is running, it continuously draws the gas inside the hollow suction plate 41 into the suction hood 43, creating a negative pressure environment inside the hollow suction plate 41. External air is drawn in through multiple suction holes 42 facing the robotic arm 2, thus cleaning the environment around the robotic arm 2. This clean environment reduces wear on the moving parts of the robotic arm 2 and the risk of overheating, extends its service life, and reduces maintenance frequency. The air drawn into the hollow suction plate 41 passes through the activated carbon filter 46. Utilizing the porous structure and adsorption characteristics of activated carbon (pore diameter approximately 0.1-20nm), it effectively captures dust particles (particle size ≥0.3μm), metal fragments, and other impurities in the air through physical adsorption and intermolecular forces, achieving gas purification. The clean gas filtered by the activated carbon filter 46 is discharged into the hollow air blowing plate 61 through the corrugated air outlet 45, and blown onto the surface of the clamping arm 3 and the surrounding area through the evenly distributed air blowing holes 62 on the plate. Due to the integrated structure design of the hollow air blowing plate 61 and the clamping arm 3, when the clamping arm 3 performs the cell clamping action, the hollow air blowing plate 61 simultaneously sprays clean air onto the surface of the cell. The impact force of the airflow (wind speed of about 5-8m / s) blows away the dust adsorbed on the surface of the cell, avoiding the formation of a "slipping layer" of dust at the contact interface between the clamping arm 3 and the cell. This maintains the effective friction coefficient between the clamping arm 3 and the cell, significantly reduces the risk of slippage during clamping, and improves the stability and assembly accuracy of cell clamping. In addition, the continuous airflow circulation can simultaneously remove the trace amount of heat generated by the movement of the clamping arm 3, which helps to improve the working environment temperature of the robotic arm 2 and indirectly improves the reliability of equipment operation. When the workshop is in a low-temperature environment (winter room temperature <10℃), the temperature sensor 8 on the clamping arm 3 monitors its surface temperature in real time and feeds back the temperature value to the PLC controller 9 in the form of an electrical signal. After receiving the signal, the PLC controller 9 automatically turns on the power supply of the heating tube 52 through the control circuit. After the heating tube 52 is started, it heats the gas drawn into the suction hood 43, raising the gas temperature to room temperature (25℃). The heated gas is evenly blown onto the surface of the battery cell through the corrugated air outlet 45, the hollow air blowing plate 61 and the air blowing hole 62, gradually increasing the temperature of the battery cell and reducing the temperature difference between the battery cell and the clamping arm 3. This process can effectively prevent condensation from occurring due to the large temperature difference when the two are in contact, maintain the dry state of the clamping arm 3 and the surface of the battery cell, thereby maintaining a high coefficient of friction and ensuring that the clamping arm 3 can quickly and accurately clamp the battery cell, helping to achieve high-precision assembly of new energy vehicle batteries. When clamping arm 3 completes the clamping of the battery cell, if the battery cell is large, clamping arm 3 needs to open at a larger angle. At this time, the external force of clamping arm 3 on pull rope 76 decreases, and the downward pull force of the other end of pull rope 76 on insulating slider 74 decreases accordingly. The degree of downward movement of insulating slider 74 against the elastic force of second spring 75 decreases, and the distance that it drives conductive ring 73 to move on resistor rod 72 is also shortened accordingly. This results in a decrease in the resistance value of resistor rod 72 connected to the circuit and an increase in circuit current. By connecting a measuring circuit to both ends of resistor rod 72, the change in current can be detected. This electrical signal is amplified and filtered. The signal is then transmitted to the PLC controller 9. After receiving the signal, the PLC controller 9 increases the current of the solenoid block 635 through the control circuit, which enhances its magnetic attraction to the permanent magnet block 634. This causes the permanent magnet block 634 to drive the moving ring 631 to move towards the solenoid block 635. The moving ring 631 will also squeeze the telescopic rod 632 and the first spring 633, causing multiple frustum-shaped sealing heads 636 to move out of the air blowing hole 62, increasing the gap with the air blowing hole 62, thereby increasing the air output and ensuring that the dust on the surface of the large-size battery cell is thoroughly cleaned, thus improving the cleaning effect. Conversely, if the cell size is small, the PLC controller 9 reduces the current of the solenoid block 635, thereby reducing the magnetic attraction force. The moving ring 631 drives the frustum-shaped sealing head 636 closer to the air blowing hole 62, reducing the gap between the frustum-shaped sealing head 636 and the air blowing hole 62 to reduce the air output. This adaptive air output adjustment design can avoid incomplete cleaning of large-sized cells due to insufficient airflow, and also prevent small-sized cells from being blown over or displaced due to excessive airflow. This improves the system's flexibility in adapting to cells of different specifications, ensuring that cells of all sizes can achieve the best cleaning effect before being clamped, and guaranteeing the accuracy and efficiency of subsequent assembly.
