Description

Technical Field

[0001] This invention relates to the field of polymer battery cell processing equipment technology, and in particular to a device for attaching side adhesive tape to polymer battery cells. Background Technology

[0002] Polymer batteries are typically wrapped with a protective tape on both sides. This tape serves two purposes: protecting the battery and enhancing its appearance. It's generally placed before the battery pack and primarily provides insulation, making it an indispensable part of the battery manufacturing process. Currently, applying this tape to the sides of batteries is mostly done by a combination of automated equipment and manual labor. However, existing automated tape-applying equipment frequently encounters problems during the application process, such as numerous air bubbles within the tape, tape wrinkles, and tape placement outside of process requirements. Furthermore, the corners at the top of the battery still require manual operation, resulting in very low production efficiency and posing safety hazards due to the need for manual edge pressing.

[0003] Faced with increasing market demand, fully automatic side tape application equipment has become a trend. At the same time, the market's requirements for tape application quality are also getting higher and higher. Problems such as air bubbles and wrinkles must not occur during the tape application process. Therefore, it is of great significance to propose a new type of polymer battery cell side tape application equipment. Summary of the Invention

[0004] The purpose of this invention is to address the technical deficiencies in the existing technology by providing a polymer battery cell side tape application device. This device can overcome problems such as air bubbles and wrinkles that occur during the tape application process, while also performing corner bending and heat pressing functions on the leading edge of the battery, achieving fully automatic edge bending and meeting product quality requirements.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0033] like Figure 1 As shown, the polymer battery cell side tape application equipment of this invention includes an automatic tray feeding unit 1, a tray buffer unit 2, an automatic tray unloading unit 3, a defective product collection unit 4, a feeding robot 5, an unloading robot 6, a turntable unit 7, a battery side hot pressing and shaping unit 8, a left side tape application robot 9, a left side tape feeding and cutting unit 10, a CCD correction detection unit 11, a right side tape feeding and cutting unit 12, a right side tape application robot 13, a roller adhesive unit 14, a top corner bending unit 15, and a top corner hot stamping unit 16.

[0034] The automatic tray feeding unit 1, the tray buffer unit 2, and the automatic tray unloading unit 3 are arranged on the feeding side of the upper surface of the equipment substrate, that is, the lower side of the equipment substrate. The feeding robot 5, the unloading robot 6, the turntable unit 7, the battery side hot pressing and shaping unit 8, the left side tape applicator robot 9, the left side tape feeding and cutting unit 10, the CCD correction and detection unit 11, the right side tape feeding and cutting unit 12, the right side tape applicator robot 13, the roller adhesive unit 14, the top corner bending unit 15, and the top corner hot stamping unit 16 are arranged on the other side of the equipment substrate, that is, the higher side of the equipment substrate.

[0035] In addition, the battery side hot pressing shaping unit 8, the left side tape applicator robot 9, the left side tape feeding and cutting unit 10, the CCD correction detection unit 11, the right side tape feeding and cutting unit 12, the right side tape applicator robot 13, the adhesive roller unit 14, the top corner bending unit 15, and the top corner hot stamping unit 16 are arranged sequentially and at intervals on the outside of the turntable unit 7 around the turntable unit 7.

[0036] The loading robot 5 is used to place the batteries from the tray containing polymer batteries, delivered by the automatic tray loading unit 1, onto the turntable unit at the battery loading station 17. The turntable unit includes a turntable 70 and multiple battery clamps arranged on the turntable. The multiple battery clamps are spaced apart around the center of the turntable and are used to clamp and fix the batteries mounted thereon. The turntable of the turntable unit is driven to rotate, moving the batteries mounted on the battery clamps to the corresponding processing position for processing, including hot pressing and shaping of the battery side, applying adhesive, rolling adhesive, top corner bending, and hot pressing of the top corner, etc., to finally complete the processing.

[0037] Specifically, the structure of the turntable unit can be referred to Figure 5 As shown, an angle divider 72 is installed at the bottom of the turntable and connected to a servo motor 71. A battery receiving plate 73 and a clamping cylinder 74 are installed on the upper surface of the turntable. The clamping cylinder 74 is connected to a battery pressing block 75. After the loading robot places the battery on the turntable, the clamping cylinder drives the battery pressing block to move, pressing the battery on the battery receiving plate 73, thereby achieving the purpose of pressing the battery. The angle divider drives the turntable to rotate at a fixed angle, transferring the battery to the hot pressing station and other stations for processing.

[0038] The left-side tape-applying robot 9 and the right-side tape-applying robot 13 are mainly used for applying tape to both sides of the battery, that is, applying insulating tape to the two sides of the battery. The unloading robot is used to take out the qualified tape-applied batteries after the tape is applied to the batteries in this equipment, and place them into the tray automatic unloading unit 3 for unloading and sending out, or to collect the unqualified batteries into the defective product collection unit 4.

[0039] The loading robot 5, unloading robot 6, left-side tape-applying robot 9, and right-side tape-applying robot 13 are all four-axis robots. The loading robot 5, using four axes, can accurately place batteries onto the eight-position turntable unit at the turntable loading station 17, with a repeatability of ±0.02mm. The unloading robot 6, also using four axes, uses a CCD appearance inspection module (installed on the robot) to inspect the tape position, presence of bubbles, wrinkles, etc., on the taped batteries. Defective products are directly collected in the defective product collection unit 4 by the unloading robot 6. The unloading robot 6 can accurately place qualified batteries into the unloading tray of the automatic tray unloading unit 3, completing the unloading of qualified batteries.

[0040] For details, see Figure 6 As shown, taking the loading robot as an example, the robot includes a four-axis robot 50, a suction cup bracket 51, and a suction cup 52. It can pick up the batteries in the tray and place them in the turntable loading station, or pick up the empty tray and place it in the tray buffer position. The robot mounting base is fixed on the equipment base plate, and the four-axis robot 50 is fixed on the top of the robot mounting base. The suction cup bracket 51 is fixed to the Z-axis end of the four-axis robot 50. The suction cup 52 is installed on the suction cup bracket and a proximity sensor is installed on it. When the robot picks up the material at the material pick-up position, the sensor senses the battery, picks up the battery, and moves the battery to the turntable station or moves the empty tray to the empty tray buffer position.

[0041] In this application, the automatic pallet feeding unit 1 and the automatic pallet unloading unit 3 are automatic feeding and unloading mechanisms, which adopt servo motors and linear module mechanisms to ensure that the repeated position of the pallet's up and down movement is accurate to ±0.02mm. The automatic pallet feeding unit 1 and the automatic pallet unloading unit 3 realize continuous feeding and unloading by moving up and down. The pallet buffer unit 2 realizes the transfer processing of the pallet, such as transferring the empty pallet used by the automatic pallet feeding unit to the automatic pallet unloading unit to become the empty pallet needed by the automatic pallet unloading unit.

[0042] The automatic pallet feeding unit 1 of this invention consists of a pallet feeding mechanism, a lifting feeding mechanism, and an empty pallet discharge mechanism. It is placed on the same side as the automatic pallet unloading unit and can place discharged empty pallets into the automatic pallet unloading unit. It has alarm functions for "missing empty pallets" and "full pallet storage". The width of the pallet feeding port is adjustable, and the width adjustment structure is a manual crank. The pallet is conveyed to the lifting feeding position, and the four sides of the pallet are positioned. The positioning effect must be stable and reliable. The pallet lifting mechanism is driven by a servo motor. After pressing the start button, full pallets are sequentially lifted to the same height. The two-sided photoelectric sensors detect the position and stop the lifting action. Each battery position in the pallet is checked for the presence of batteries. After confirming that a battery is present at that position, the feeding robot grabs the battery according to the calibrated picking point coordinates and moves it to the next station. After all batteries in each pallet are picked up, the empty pallet is placed in the empty pallet discharge station or placed in the automatic pallet unloading station.

[0043] The pallet feeding mechanism of the automatic pallet feeding unit 1 is as follows: Figure 4 As shown, it includes a lifting module and a tray carrier. Its function is to lift a fully loaded battery tray to a specified height. The module fixing plate 13 is fixed on the equipment frame. The front of the module fixing plate 13 is fixedly connected to the servo module 11. The sliding block of the servo module 11 is fixedly connected to the tray bracket 12. The top of the tray bracket 12 is used to place the batteries to be processed and the tray.

[0044] The battery side hot pressing shaping unit of the present invention performs side hot pressing shaping of the battery. Its control parameters are hot pressing for 2 seconds, 50-125℃; temperature control accuracy ±2℃; temperature display accuracy 0.1℃. During the shaping process, the battery body has a limit mechanism to prevent the battery from tilting. The hot pressing block is equipped with a protective cover to prevent burns. The side shaping cylinder has a limit control structure to prevent the battery from deforming due to excessive pressure or uneven pressure.

[0045] The battery side hot pressing shaping unit 8 may include a gripper cylinder 83, a hot plate 86, and a slide cylinder 80. Its main function is to energize the heating tube to raise the temperature of the hot plate to a set value. After the battery is transferred, the slide cylinder 80 rises, the gripper cylinder 83 moves, and the hot plate 86 clamps the battery to perform battery side hot pressing shaping. After the battery side hot pressing shaping is completed, the gripping cylinder opens, the slide cylinder 80 descends, and the battery is transferred to the adhesive application station.

[0046] The fixed plate 88 is fixed to the top of the equipment base plate. The fixed plate 88 is fixed to the side of the slide cylinder 9. The top of the slide cylinder 9 is fixed to the lifting connecting block 81. The top of the lifting connecting block 81 is fixed to the support block 82. The top of the support block 82 is fixed to the clamping cylinder 83. The top of the slider connected to the clamping cylinder 83 is fixed to the end support frame 84. The end of the end support frame 84 is fixed to the heat insulation block 85. The end of the heat insulation block 85 is fixed to the heat-scalding block 86. The heat-scalding block 86 contains a heating tube 87. After the battery is transferred, the slide cylinder 80 extends and the clamping cylinder 83 clamps it for heat-scalding treatment. After the heat-scalding treatment is completed, the clamping cylinder releases and the slide cylinder retracts.

[0047] In this application, in order to ensure that the tape position meets the process requirements, two tape-applying robots using a four-axis robot grip the tape and apply the tape. When applying the tape to the side of the battery, the two tape-applying robots use a CCD correction mechanism 11 to take pictures of the tape and the battery to be tapeped at the same time. After the picture data is completed, the two tape-applying robots using the four-axis robot grip the tape and apply the tape according to the coordinates fed back by the PLC.

[0048] The two tape-applying robots of this invention perform visual recognition of the tape and battery cell positions before parallel tape application to ensure accurate tape application that meets preset requirements. Furthermore, the tape width on the marked side of the battery after wrapping can be adjusted via servo motor parameters, with the tape width adjustment on this side requiring precision to 0.1mm. Additionally, a linear module is used for tape preparation and application to ensure the correct tape length.

[0049] In specific implementation, the tape-applying robot, taking the left-side example, includes a tape suction plate and a rotary motor. The tape suction plate is connected to the rotary motor. The robot, equipped with the rotary motor and tape suction plate, moves to the tape-picking position. After the tape is cut, the tape suction plate operates, picking up the tape. The robot then transfers the picked-up tape to the CCD correction detection unit 11 for correction. After the tape position is corrected, the tape is applied to the side of the battery for tape application. The robot mounting base is fixed to the top of the equipment base plate. A four-axis manipulator is fixed to the top of the robot mounting base. A connecting block 90 is fixed to the lower end of the Z-axis of the four-axis manipulator. A motor connecting plate 91 is fixed to the lower end of the connecting block 90. ​​A rotary motor 93 is fixed to the right end of the motor connecting plate 91. The tape suction plate 92 is fixed to the output shaft end of the rotary motor 93.

[0050] In this application, the tape feeding and cutting unit is described in [reference needed]. Figure 9 As shown, taking the left-side tape feeding and cutting unit as an example, it includes a tape roll 100 and a tape pulling module 111. A tape cutter 116 is arranged between the tape roll and the tape pulling module. The tape cutter is mounted on a cutter bracket 115, which is connected to a tape cutting cylinder 114. A tape clamping cylinder 112 is provided on the tape pulling module, which is connected to a gripper 113. The tape pulling module carries the clamping cylinder to the tape picking position, the clamping cylinder actuates, and the gripper clamps the tape. The tape pulling module then moves to a set position, and the tape cutting cylinder carries the cutter to cut the tape. After cutting, the tape applicator robot sucks the tape away.

[0051] Specifically, the mechanism bracket 118 is fixed to the equipment. The top of the mechanism bracket 118 is fixed to the support plate 110. The top of the support plate 110 is fixed to the tape support frame 126. The top of the tape support frame 126 is fixed to the tape fixing shaft to install the tape roll 100. The top of the support plate 20 is fixed to the tape tension roller 125, the tape pressing plate 119, the tape pressing plate 124, and the pressing cylinder 123. The lever end of the pressing cylinder 123 is fixed to the pressing drive block 122. The end of the pressing drive block 122 is fixed to the pressing block 121. The end of the pressing drive block 122 is fixed to the support shaft 120. The bottom of the support shaft 120 is fixed to the top of the support plate 20.

[0052] The roller coating mechanism of this invention functions as follows: after the battery arrives, the height adjustment module rises, the pressing cylinder extends to press the battery, and the roller coating cylinder extends to complete the roller coating action. Afterwards, the roller coating cylinder retracts, the pressing cylinder retracts, the height module returns to the initial position, and the battery flows to the corner station for wrapping the applied tape. The wrapping process does not cause the battery to bend, and the wrapped tape is guaranteed to be free of curling, air bubbles, and wrinkles. The roller coating process is carried out by first heat-shaping the sides of the battery and then performing a compression roller coating method.

[0053] In this application, the roller adhesive unit is described in [reference needed]. Figure 10As shown, the device may include a roller coating mechanism and a height adjustment mechanism. The roller coating mechanism is mounted on a support plate, and a height adjustment mechanism is installed at the bottom of the support plate to adjust the height of the roller coating mechanism. A lifting module 33 is fixed to the front of the support plate used for fixing to the equipment base plate to form the adjustment mechanism. A connecting plate is fixed to the slider end of the lifting module 33, and the support plate is fixed to the top of the connecting plate. The roller coating mechanism includes a pressing cylinder 145 fixed to the top of the support plate by a cylinder bracket. A pressing connecting plate 146 is fixed to the top of the pressing cylinder 145, and a side pressing plate 149 is fixed to the top of the pressing connecting plate 146. In addition, a roller coating cylinder 142 is fixed to the top of the support plate, and a roller coating bracket 148 is fixed to the top of the slider of the roller coating cylinder 142. Two linear bearings are fixed to the upper and lower ends of the roller coating bracket 148. Each linear bearing is connected to a guide shaft 141. A roller coating support plate 144 is fixed to both ends of the guide shaft 141, and a glue roller 143 is fixed to the end of the roller coating support plate 144.

[0054] In a preferred embodiment, there are two roller support brackets 148 arranged opposite to each other. Each roller support bracket has two roller support plates 144 spaced vertically apart. The side pressing plate 149 can move between the two spaced roller support plates 144 to press the sides of the battery. The roller support brackets 148 are provided with space for the movement of the side pressing plates 149. There are two pressing cylinders 145 arranged opposite to each other, corresponding to two side pressing plates 149.

[0055] In this application, the top corner folding unit 15 and the top corner hot-pressing unit 16 use mechanical corner folding and hot-pressing methods to replace manual methods, and are used to fold and hot-press the leading edge of the top of the battery cell / battery packaging. The top corner folding of this invention uses the leading edge of the battery as a reference, and employs a rolling structure to bend the two leading corners of the battery packaging from both sides of the battery. After bending, the leading edge is flat, compatible with dual-pit batteries, and will not damage the battery body or the leading edge of the battery. The top corner hot-pressing unit 16 of this invention has a hot-pressing and hot-pressing time of 2 seconds, a clamping temperature of 50-125℃, and a bending angle of 30°-60°.

The bending cylinder 154 is mounted on a sliding bracket 153, which is connected to a linear guide rail 156 on a support plate and to a pressing cylinder 150. (Specifically, the sliding bracket 153 is connected to the connecting block 152, the connecting block is connected to a floating joint, and the floating joint is connected to the piston rod of the pressing cylinder 150.) A movable positioning frame 159 is provided below the bending cylinder 154.

Its function is that after the battery flows to the station, the pressing cylinder and the lifting cylinder extend, the bending cylinder drives the bending fixture to extend, so that the top of the battery needs to be bent at a bending angle. Then the pressing cylinder and the lifting cylinder retract, the bending cylinder retracts, and the battery flows to the hot pressing station.

[0057] In this application, the top corner heat-pressing unit 16, see [link to application]. Figure 12 As shown, the heating module includes a heating tube 164 and two heating blocks 163, which are spaced apart on the outer wall of the heating module on which the heating tube 164 is installed. The upper end of the heating module is connected to a connecting block 162 and a sliding block 165. The sliding block is linearly slidably connected to a linear guide rail 166 on a support plate 169. The upper end of the connecting block is connected to a floating joint 161, which is connected to a hot ironing pressing cylinder 160.

If the connection is made through a floating joint and a connecting plate, please refer to the connection structure or method of the hot ironing pressing cylinder 160 and the connecting block 162. Its function is that after the battery is transferred, the hot pressing cylinder and the hot lifting and positioning cylinder extend to press down on the bent part of the battery. After a predetermined time, the hot pressing cylinder and the hot lifting and positioning cylinder retract, and the battery is transferred to the unloading station.

[0058] In this application, the tray cache unit is described in [reference needed]. Figure 13As shown, a lifting buffer tray carrier 20 is installed above a support plate 23 via four carrier guide shafts 21. A rod reducer 26 is installed below the support plate and is connected to the buffer tray carrier 20 for transmission, controlling the buffer tray carrier 20 to rise and fall along the carrier guide shafts. Its main function is to use the rod reducer to drive the buffer tray carrier to move up and down along the carrier guide shafts, and to control the position of the up and down movement through sensors to realize the buffering use of the tray.

[0059] Additionally, a tray limiting plate 22 is provided on the outer periphery of the cache tray carrier 20 to limit the position of the tray. An extreme position fixing shaft 28 is fixed at the bottom of the support plate 23, and a limit sensor 27 is fixed on the extreme position fixing shaft 28.

[0061] The support panel 43 is provided with four limiting plates 42, which cooperate with the limiting holes formed on the defective product collection tray carrier 40 to form a limiting structure for the tray. A lifting limiting shaft 45 is fixed to the bottom of the support panel 43 and extends to the bottom of the support panel. A limiting piece 46 is installed at the lower end of the lifting limiting shaft 45. A lifting limit fixing block 47 is fixed at the bottom of the support panel, and a lifting limit sensor 48 is fixed on the lifting limit fixing shaft 47. The lifting and lowering of the defective product collection tray carrier 40 is controlled by the cooperation of the limiting piece 46 and the lifting limit sensor 48.

[0062] The support panel 43 can be fixed to the top of the equipment base plate by four support rods. The bottom of the support panel 43 is fixed with a lifting reducer 11. The output end of the lifting reducer 11 is connected to the defective product collection tray carrier 40 through the support panel.
