[0030] Please also read Figure 3 Each glue-applying assembly includes a glue-applying unit, a first deflection-correcting unit, a second deflection-correcting unit, and a deflection-correcting control unit.

[0031] The unwinding and gluing unit includes a support plate 1, an unwinding reel 2 mounted on the support plate 1, several rollers 3, a splicing mechanism 4, a tensioning mechanism 5, a first gluing roller 6, a first heater 7, and a second gluing roller 8. The support plate 1 is arranged vertically and perpendicular to the surface of the battery electrode. The unwinding reel 2 can be rotated by a servo motor. The first gluing roller 6, the first heater 7, and the second gluing roller 8 are arranged in sequence along the battery electrode transport direction (in this embodiment, they are arranged horizontally from right to left). Several rollers 3 are located between the unwinding reel 2 and the first gluing roller 6, feeding the adhesive tape 300 onto the first gluing roller 6. The splicing mechanism 4 is located between two adjacent rollers 3 and is used to bond the leading edge of the next roll of tape to the trailing edge of the previous roll. The tensioning mechanism 5 includes a tensioning roller 51 and an angle potentiometer 52 for driving the tensioning roller 51. The tensioning roller 51 is located to the left of the gap between two adjacent rollers 3. The first heater 7 is a non-contact infrared focused heater, which can heat the battery electrode and the adhesive tape 300 between the first adhesive roller 6 and the second adhesive roller 8, so that the adhesive tape 300 can adhere to the battery electrode.

[0032] The first correction unit is installed on the support plate 1, including a correction mechanism 9 and an ultrasonic sensor 10. Figure 7 The deflection correction mechanism 9 includes a deflection correction roller 91, a bracket 92 and a deflection correction driver 93. The deflection correction driver 93 is used to drive the deflection correction roller 91 to swing, and has a power output shaft. The bracket 92 is fixedly mounted on the power output shaft of the deflection correction driver 93. The deflection correction roller 91 is rotatably mounted on the bracket 92, and its rotation axis is perpendicular to the power output shaft of the deflection correction driver 93. The deflection correction roller 91 is located parallel to two rollers 3 arranged one above the other. The ultrasonic sensor 10 is located between two adjacent rollers 3 and upstream of the deflection correction roller 91 in the transmission direction of the tape 300. It is used to detect the position deviation of the tape 300 and feed back the signal to the deflection correction control unit.

[0033] The second correction unit is mounted on the support plate 1 and includes an optical corrector 11 and a transmission mechanism 12. The optical corrector 11 is mounted on the support plate 1, to the right of the first adhesive roller 6, and is used to detect the positional deviation of the battery electrode and provide feedback to the correction control unit. The transmission mechanism 12 is mounted on the bracket 100 and is used to drive the support plate 1 in horizontal translation. The support plate 1 is mounted on the transmission mechanism 12.

[0034] The correction control unit is used to control the operation of the correction mechanism 9 and the transmission mechanism 12. It is electrically connected to the ultrasonic sensor 10, the optical corrector 11, the correction driver 93 and the transmission mechanism 12. It can control the operation of the correction driver 93 and the transmission mechanism 12 according to the signals fed back by the ultrasonic sensor 10 and the optical corrector 11, respectively, and then make the correction roller 91 swing a specified angle to compensate for the position deviation of the tape 300, and make the support plate 1 translate a specified distance to compensate for the position deviation of the battery electrode.

[0035] The above-mentioned unwinding and gluing unit is used to stick the tape 300 to the specified position of the battery electrode. The unwinding disk 2 can be driven by a servo motor. The tape 300 is a whole roll of material. The size of the material roll can be measured by the laser ranging sensor 13 and fed back to the servo motor of the unwinding disk 2. The servo motor adjusts the speed according to the measurement results to ensure that the unwinding linear speed is uniform.

[0036] Please also read Figure 4 The above-mentioned tape splicing mechanism 4 includes a base 41, a heating module 42 and a tape splicing pressure head 43 that can move up and down. The base 41 is horizontally installed on the support plate 1, and a mounting groove 411 is provided on it. The heating module 42 is located in the mounting groove 411, and its upper surface is flat and exposed on the top surface of the base 41. The tape splicing pressure head 43 is located above the heating module 42. The tape splicing pressure head 43 includes a pressure plate 431, a connecting column 432, a pin 433, a spring 434 and a guide sleeve 435. The connecting column 432 is perpendicular to the upper surface of the heating module 42, the pressure plate 431 is located at the bottom end of the connecting column 432, and is parallel to the upper surface of the heating module 42. The guide sleeve 435 is placed on the end of the connecting column 432 away from the pressure plate 431. The guide sleeve 435 is provided with a T-shaped guide slot 4351, which includes a horizontal slot parallel to the upper surface of the heating module 42 and a vertical slot perpendicular to the upper surface of the heating module 42. The pin 433 passes through the connecting column 432 and the guide slot 4351 and is parallel to the upper surface of the heating module 42. The base 41 is provided with a base bracket 412, and the guide sleeve 435 is mounted above the base bracket 412. The spring 434 is elastically compressed and clamped between the base bracket 412 and the pressure plate 431. In addition, the tape splicing mechanism 4 also includes a K-type thermocouple 44, which is used to detect the heating temperature of the heating module 42 to prevent excessively high or low temperatures from affecting the viscosity of the tape 300.

[0037] When the tape is not connected, pin 433 is located in the horizontal groove of guide slot 4351, pressure plate 431 is suspended in the air, and spring 434 is in a compressed state. When the tape is connected, pin 433 is manually moved downward along the vertical groove of guide slot 4351. During this process, spring 434 extends under the elastic restoring force, thereby driving pressure plate 431 and connecting column 432 downward, causing pressure plate 431 to press against tape 300.

[0038] When splicing, the tape 300 is fed horizontally ( Figure 4 The direction of the middle arrow indicates the conveying direction of the tape 300). During the transverse movement of the tape 300, the bottom heating module 42 ensures the adhesiveness of the tape 300. During the heating process, the K-type thermocouple 45 measures the heating temperature of the heating module 42 to prevent the temperature of the tape 300 from being too high or too low. The tape pressing head 43 presses the tape 300 downward so that it fits the upper surface of the heating module 42 and is fully heated. When changing materials, the tape 300 is fixed and then cut, and the cycle is repeated to complete the production process.

[0039] The angle potentiometer 52 of the tensioning mechanism 5 has an encoder and a controller for measuring and controlling the swing angle of the tensioning roller 51 , and feeding back the position to compensate the unwinding speed to adjust the moving speed of the tape 200 .

[0040] Please also read Figure 5 The first heater 7 comprises a lamp housing 71, an infrared heating tube, and a light concentrator. One side of the lamp housing 71 is recessed to form a housing space, with the open end of the housing space serving as a light outlet. Both the infrared heating tube and the light concentrator are mounted within the housing space, with the infrared heating tube positioned between the light outlet and the light outlet, extending parallel to the direction in which the battery electrodes are transported.

[0041] The lamp housing 71 is provided with two water connectors 711 for the inlet and outlet of cooling water, respectively. A water channel is provided inside the lamp housing 71, and the water channel connects the two water connectors 711. The water connectors 711 are connected to a water chiller, respectively for the inlet and outlet of water. As the cooling water flows through the lamp housing 71, it can remove heat from the lamp housing 71 and reduce the temperature of the lamp housing 71. In addition, the lamp housing 71 is also provided with at least two air connectors 712, which are connected to the storage space of the lamp housing 71. One of the air connectors 712 can be connected to compressed air, and the other can be connected to an exhaust fan, so that air is taken in and exhausted at the same time, or all the air connectors 712 can be connected to an exhaust fan, so that air is exhausted at the same time, so that air flows in the storage space of the lamp housing 71, thereby removing heat from the storage space and the lamp housing 71, reducing the temperature of the lamp housing 71 and the storage space, making the equipment safer, improving product quality, and reducing the probability of damage during battery electrode production.

[0042] In addition, the first heater 7 further includes a first thermocouple 72 and a second thermocouple 73. The first thermocouple 72 is used to detect the temperature of the battery electrode, and the second thermocouple 73 is used to detect the temperature of the lamp housing 71. Both the first and second thermocouples 72 and 73 are mounted on the lamp housing 71 to better control the device temperature and ensure safety.

[0043] The above-mentioned first heater 7 emits the infrared light emitted by the infrared heating tube from the light outlet of the lamp housing 71, and focuses it to the part of the battery electrode that needs to be heated through the focusing plate, thereby realizing non-contact heating of the battery electrode. The first heater 7 dissipates heat to the lamp housing 71 and the accommodating space of the lamp housing 71 at the same time through water cooling and air cooling. Under the premise of not affecting the heating effect, the inside of the heater and the surrounding air can be cooled to prevent damage to the battery electrode and the operator.

[0044] In order to make the adhesive tape 300 more firmly attached to the battery electrode, the above-mentioned unwinding and gluing unit also includes a second heater 14. The second heater 14 is installed on the support plate 1 and is located between the first gluing roller 6 and the optical deflection corrector 11. It is used to preheat the battery electrode before entering the area of ​​the first gluing roller 6. When the battery electrode passes through the area of ​​the second heater 14, the second heater 14 can heat the battery electrode at room temperature to a temperature at which the electrode can be glued. In this way, when the preheated battery electrode moves to the first gluing roller 6, the adhesive tape 300 can be attached to the battery electrode. After the subsequent secondary pressing by the second gluing roller 8, the bonding strength between the battery electrode and the adhesive tape 300 can be enhanced to prevent false adhesion. In this embodiment, the structure of the second heater 14 is the same as that of the first heater 7 and will not be repeated here.

[0045] Please also read Figure 6 Considering that there is a section of the battery electrode between the second heater 14 and the first gluing roller 6 where the tape 300 is not adhered, which cools down after power is turned off, the second heater 14 cannot heat this section after power is turned on, and the tape 300 cannot adhere to this section of the battery electrode. In this embodiment, the first gluing roller 6 includes a first gluing roller 61 and a heating tube, which is installed inside the first gluing roller 61. The heat generated by the heating tube can be transferred to the first gluing roller 61, and through the first gluing roller 61, it is attached to the tape 300, achieving contact heating of the tape 300. The first gluing roller 6 can simultaneously heat the tape 300 while squeezing it, thereby better ensuring the bonding effect of the adhesive on the tape 300.

[0046] In this embodiment, the first adhesive roller 6 also includes a pressure regulating module, which includes a lift cylinder 62, a pressure sensor 63, and a pressure controller. The first adhesive roller 61 is connected to the piston of the lift cylinder 62 and can move with the piston of the lift cylinder 62. The pressure sensor 63 is used to detect the pressure between the adhesive tape 300 and the first adhesive roller 61. The pressure controller is used to adjust the air pressure of the lift cylinder 62 based on the feedback signal from the pressure sensor 63. This adjustment ensures that the first adhesive roller 61 and the adhesive tape 300 are properly aligned and heat is transferred, preventing the adhesive tape 300 from being damaged by excessive pressure.

[0047] The first adhesive roller 6 further includes a temperature probe 64 and a temperature controller. The temperature probe 64 is used to detect the temperature of the adhesive tape 300 . The temperature controller is used to control the temperature of the heating tube according to the feedback signal of the temperature probe 64 to prevent the heating temperature of the adhesive tape 300 from being too high or too low.

[0048] During operation, the lifting cylinder 62 drives the first adhesive roller 61 to contact the tape 300. The pressure sensor 63 detects the pressure between the first adhesive roller 61 and the tape 300 and feeds it back to the pressure controller. Based on the signal from the pressure sensor 63, the pressure controller issues a command to adjust the air pressure in the lifting cylinder 62, ensuring proper contact and heat transfer between the first adhesive roller 61 and the tape 300. Simultaneously, the temperature probe 64 detects the temperature of the tape 300 and feeds it back to the temperature controller. Based on the signal from the temperature probe 64, the temperature controller issues a command to adjust the temperature of the heating tube, ensuring that the first adhesive roller 61 provides the appropriate contact heating temperature to the tape 300, preventing overheating or insufficient heating.

[0049] The second gluing roller 8 is used to re-press the adhesive tape 300 onto the battery electrode, thereby enhancing the bonding strength between the battery electrode and the adhesive tape 300 and preventing loose adhesion. In this embodiment, the structure of the second gluing roller 8 is similar to that of the first gluing roller 6, including a second gluing roller and a pressure regulating module. The main difference is that the second gluing roller does not have a heating function and does not have a heating tube, a temperature probe, or a temperature controller. The structure of the second gluing roller 8 is not further described here.

[0050] Please refer to Figure 7 again. The aforementioned deflection correction control unit controls the deflection correction driver 93 based on the feedback signal from the ultrasonic sensor 10, driving the deflection correction roller 91 to swing to a corresponding angle. In this embodiment, the deflection correction driver 93 comprises a motor and a reducer. The motor is a servo motor, whose shaft is connected to the reducer. The reducer's shaft (i.e., the power output shaft of the deflection correction driver 93) is connected to the bracket 92. The deflection correction roller 91 is rotatably mounted on a roller shaft. One end of the roller shaft is fixedly mounted on the bracket 92, and the roller shaft is perpendicular to the power output shaft of the deflection correction driver 93. The motor drives the bracket 92 to rotate via the reducer, causing the deflection correction roller 91 to swing along with the bracket 92.

[0051] During operation, the ultrasonic sensor 10 performs real-time detection of the position of the tape 300 entering the roller 3, detects the edge of the tape 300, determines whether the position of the tape 300 is deflected and the extent of the deflection, and outputs the information to the correction control unit, which calculates whether correction is required and the extent of the correction. When the tape 300 runs to the correction roller 91, the correction control unit controls the correction driver 93 to drive the correction roller 91 to deflect by a corresponding angle based on the deviation of the tape 300, thereby correcting the position of the tape 300. When the position of the tape 300 deflects toward the support plate 1, the correction control unit controls the correction roller 91 to swing counterclockwise; conversely, when the position of the tape 300 deflects away from the support plate 1, the correction control unit controls the correction roller 91 to swing clockwise.

[0052] In this embodiment, the transmission mechanism 12 includes a motor, a screw and a screw nut. The screw is connected to the motor in a transmission manner, which is perpendicular to the transmission direction of the battery electrode and parallel to the surface of the battery electrode. The screw nut is installed on the screw, and the support plate 1 is fixed on the screw nut. When the motor drives the screw to rotate, the screw nut translates along the screw, thereby driving the support plate 1 to translate, and the support plate 1 then drives all components installed thereon to move together. The above-mentioned correction control unit can control the motor to drive the screw to rotate according to the feedback signal of the optical corrector 11, thereby driving the support plate 1 to translate a corresponding distance.

[0053] The working process of the above-mentioned horizontal tape laminating equipment is roughly as follows:

[0054] Four rolls of tape are manually mounted on the support plates 1 of the four adhesive laminating assemblies (i.e., the unwinding reels 2). The size of the tape roll is measured by a laser ranging sensor 13 and fed back to the servo motor of the unwinding reel 2. The servo motor adjusts the speed based on the measurement results to ensure a uniform linear speed of unwinding.

[0055] The unwinding and gluing unit transfers the tape 300 to the tape splicing mechanism 4. When splicing is required, the tape splicing mechanism 4 heats and presses the tape 300 during the transfer process.

[0056] Then, the adhesive tape 300 is conveyed to the tensioning mechanism 5, and the speed of the adhesive tape is corrected by the tensioning mechanism 5;

[0057] After the correction is correct, the tape 300 passes through the ultrasonic sensor 10, which senses whether there is any deviation, and transmits the data to the correction mechanism 9, which corrects the deflected part of the tape 300 to prevent the tape 300 from deviating;

[0058] Then, the adhesive tape 300 is conveyed to the first adhesive roller 6, where the adhesive tape 300 is heated to be attached to a designated position on the battery electrode.

[0059] The battery electrode is fed from the right side and is detected by the optical deflection corrector 11 to see if there is any deviation. If there is any deviation, the transmission mechanism 12 drives the support plate 1 to move according to the data of the optical deflection corrector 11. The support plate 1 then drives all components mounted on it to move together, thereby compensating for the deviation and ensuring that the adhesive tape 300 and the battery electrode are accurately attached.

[0060] After the adhesive tape 300 is applied, the battery electrode is heated by the first heater 7 , and then the second adhesive roller 8 applies pressure to the adhesive tape 300 for application.

[0061] During the lateral movement of the battery electrode, the second heater 14 may first heat the battery electrode to a temperature at which the adhesive tape 300 can be adhered, thereby facilitating the attachment of the adhesive tape 300 to the battery electrode.

[0062] This horizontal tape-applying machine features automated operation, resulting in high production efficiency. Furthermore, the first and second deflection-correcting units detect positional deviations between the tape 300 and the battery electrode, ensuring precise application and a high yield rate. Furthermore, the four adhesive-applying components are staggered vertically and horizontally, creating a convenient structure that facilitates the removal of the tape 300.

[0063] The above embodiments are only preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be regarded as equivalent replacement methods and are included in the scope of protection of the present invention.
