Description

Technical Field

[0001] This invention relates to the field of battery manufacturing equipment technology, and in particular to an adhesive applicator, a core rod feeding device, and a battery winding machine. Background Technology

[0002] Battery cells are a crucial component of batteries. Cylindrical cells, for example, are typically manufactured using a winding process. During winding, the core rods are first fed one by one to the winding station. The notch at the end of the core rod engages with the winding needle at the station, allowing the needle to rotate the core rod. As the needle rotates the core rod, the material wraps around it to form the battery cell.

[0003] To ensure the mandrel can wind the strip (e.g., diaphragm strip), double-sided tape needs to be applied to the mandrel to attach the starting end of the strip to it. However, existing mandrel feeding equipment has a low degree of automation and requires manual application of the double-sided tape, resulting in low mandrel feeding efficiency. Summary of the Invention

[0004] Therefore, it is necessary to address the problem that the existing core rod feeding equipment has a low degree of automation and requires manual intervention to apply double-sided tape, resulting in low core rod feeding efficiency. In this regard, an adhesive application device, core rod feeding equipment, and battery winding machine should be provided to improve the above defects.

[0005] An adhesive applicator, comprising:

[0006] The motion mechanism includes a first drive assembly and a transfer seat that is pulsatorically connected to the first drive assembly. The first drive assembly is used to drive the transfer seat to move along a second direction and a third direction, wherein the second direction intersects with the third direction.

[0007] An unwinding mechanism, disposed on the transfer seat, is used to unwind double-sided adhesive tape, the double-sided adhesive tape comprising stacked double-sided adhesive layers and a release film;

[0008] A winding mechanism, disposed on the transfer seat, is used to wind up the release film;

[0009] An adhesive applicator is mounted on the transfer seat and has an applicator wheel through which the double-sided adhesive tape is wound; and

[0010] A cutting mechanism, disposed on the transfer seat, is used to cut the double-sided adhesive layer from the upstream side of the adhesive-applying wheel;

[0011] During the movement of the transfer seat along the third direction, it can drive the adhesive roller to press the double-sided adhesive layer against the mandrel; during the movement of the transfer seat along the second direction, it can drive the adhesive roller to roll along the surface of the mandrel.

[0012] In one embodiment, the adhesive applicator further includes a pressing mechanism disposed on the transfer seat, the pressing mechanism having a pressing wheel located downstream of the adhesive applicator wheel;

[0013] When the adhesive roller presses the double-sided adhesive layer against the mandrel, the pressing roller abuts against the mandrel so that, as it moves along the second direction with the transfer seat, the pressing roller smooths the double-sided adhesive layer adhered to the mandrel.

[0014] In one embodiment, the peripheral surface of the pressure roller is recessed inward to form a concave surface, which is used to match the peripheral surface of the mandrel.

[0015] In one embodiment, the pressing mechanism includes a connecting seat, a support shaft, and a second elastic element. The connecting seat is disposed on the transfer seat, the support shaft is movably connected to the connecting seat, and the pressing wheel is rotatably connected to the support shaft.

[0016] The second elastic element abuts between the support shaft and the connecting seat to provide a preload force that causes the support shaft to have a tendency to move towards the mandrel.

[0017] In one embodiment, the adhesive applicator further includes a first limiting block, and the cutting mechanism includes a cutter seat, a cutter disposed on the cutter seat, and a second limiting block. The cutter seat is disposed on the transfer seat. The first limiting block and the second limiting block are disposed opposite to each other along the second direction, and a gluing channel for the double-sided tape to pass through is formed between the first limiting block and the second limiting block. The gluing channel is located on the upstream side of the adhesive applicator wheel.

[0018] The cutter holder can move along the second direction toward the adhesive applicator to the cutting position; when the cutter holder moves to the cutting position, the second limiting block abuts against the first limiting block, and the cutter cuts the double-sided adhesive layer between the first limiting block and the adhesive applicator wheel.

[0019] In one embodiment, the adhesive applicator further includes an adhesive applicator seat disposed on the transfer seat, the adhesive applicator wheel being rotatably connected to the adhesive applicator seat, and the first limiting block being disposed on the adhesive applicator seat and being adjustable in position relative to the adhesive applicator seat along the second direction.

[0020] In one embodiment, the first limiting block is movably connected to the adhesive base along the second direction, and the first limiting block has a first inclined surface; the adhesive applicator further includes an adjusting wedge disposed on the adhesive base, the adjusting wedge having a second inclined surface that is parallel to and fits against the first inclined surface;

[0021] The adjusting wedge is movable relative to the adhesive base in a preset direction perpendicular to the second direction, so as to push the first limiting block to move in the second direction under the guidance of the first inclined surface and the second inclined surface.

[0022] In one embodiment, the adhesive base has a stop surface located on the side of the first limiting block away from the second limiting block, and the adjusting wedge is located between the first limiting block and the stop surface; the stop surface is parallel to a plane perpendicular to the second direction.

[0023] In one embodiment, the adhesive applicator further includes an adjusting screw, which is rotatably connected to the adhesive applicator about its own axis. The axis of the adjusting screw is parallel to the preset direction, and one end of the adjusting screw is threadedly connected to the adjusting wedge.

[0024] A mandrel feeding device includes an adhesive applicator as described in any of the above embodiments.

[0025] A battery winding machine includes the core rod feeding device as described in any of the above embodiments.

[0026] In the actual adhesive application process of the aforementioned adhesive application device, core rod feeding equipment, and battery winding machine, the transfer seat first moves towards the core rod along a third direction until it drives the adhesive application wheel to press the double-sided adhesive tape against the core rod. At this time, the double-sided adhesive layer of the double-sided adhesive tape is in contact with the surface of the core rod, and the release liner of the double-sided adhesive tape is located between the double-sided adhesive layer and the adhesive application wheel. Then, the transfer seat moves a preset distance along a second direction (i.e., the axial direction of the core rod) (while the winding mechanism winds up the release liner and the unwinding mechanism unwinds the double-sided adhesive tape), thereby driving the adhesive application wheel to roll along the surface of the core rod to adhere the double-sided adhesive layer to the core rod. Next, the cutting mechanism cuts the double-sided adhesive layer of the double-sided adhesive tape from the upstream side of the adhesive application wheel (without cutting the release liner of the double-sided adhesive tape), and the cut double-sided adhesive layer is then adhered to the core rod. Then, the transfer seat moves away from the core rod along a third direction and returns to the initial position to prepare for the next adhesive application operation. Thus, the above-mentioned adhesive application device can achieve automatic and continuous adhesive application, with a high degree of automation and a stable and reliable adhesive application process, which is conducive to improving adhesive application efficiency and the stability of adhesive application quality.

[0063] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a mandrel feeding device, which has a blanking station B1, an adjustment station B2, an adhesive application station B3, and a feeding station (not shown in the figure). The mandrel feeding device includes a transfer device 10, a blanking device 20, an adjustment device 30, an adhesive application device 40, and a feeding device 50.

[0064] The transfer device 10 is movable to the aforementioned unloading station B1, adjustment station B2, adhesive application station B3, and loading station. The unloading device 20 is located at the unloading station B1 and is used to store and output mandrels A one by one. When the transfer device 10 moves to the unloading station B1, it can receive the mandrels A output by the unloading device 20. The adjustment device 30 is located at the adjustment station B2 and is used to rotate the mandrels A transferred from the transfer device 10 to the adjustment station B2 until the positioning part a1 on the mandrel A is in a preset position, so that the positioning part a1 on the mandrel A matches the winding needle of the winding mechanism D. The adhesive applicator 40 is located at the adhesive applicator station B3 and is used to apply a double-sided adhesive layer a2 to the mandrel A transferred from the transfer device 10 to the adhesive applicator station B3. This allows the mandrel A to adhere to the winding tape (which can be a diaphragm) using the double-sided adhesive layer a2 when it is fed onto the winding needle of the winding mechanism D. As the winding needle rotates the mandrel A, the winding tape can be wound around the mandrel A. The feeding device 50 is located at the feeding station and is used to pick up the mandrel A transferred from the transfer device 10 to the feeding station and transfer the picked-up mandrel A to the winding mechanism D. This allows the winding needle of the winding mechanism D to insert into the mandrel A and engage with the positioning part a1 of the mandrel A. Optionally, the positioning part a1 can be a notch or protrusion on the mandrel A, used for positioning and engaging with the winding needle, allowing the winding needle to rotate the mandrel A on it.

[0065] In the aforementioned mandrel feeding equipment, during actual feeding operations, multiple mandrels A are stored on the unloading device 20, and the unloading device 20 outputs mandrels A one by one. The transfer device 10 moves to the unloading station B1 to receive the mandrels A output by the unloading device 20. Then, the transfer device 10 carries the mandrels A to the adjustment station B2, where the adjustment device 30 operates to drive the mandrel A to rotate until the positioning part a1 on the mandrel A rotates to a preset position so that the winding needle can match the positioning part a1 when the mandrel A is transferred to the winding mechanism D. Then, the transfer device 10 carries the adjusted mandrels A to the adhesive application station B3, where the adhesive application device 40 applies a double-sided adhesive layer a2 to the mandrel A on the transfer device 10. Next, the transfer device 10 carries the mandrel A with the double-sided adhesive layer a2 attached to it to the loading station. At this time, the loading device 50 clamps the mandrel A from the transfer device 10 and transfers the mandrel A to the winding mechanism D. Then, the winding needle of the winding mechanism D inserts into the mandrel A and positions and matches it with the positioning part a1 on the mandrel A. Then, the loading device 50 releases the mandrel A and returns to the loading station, thus completing the loading of one mandrel A. In this way, the transfer device 10 realizes the transfer of the mandrel A between the unloading station B1, the adjustment station B2, the adhesive application station B3, and the loading station. Furthermore, the unloading device 20, the adjustment device 30, the adhesive application device 40, and the loading device 50 sequentially complete the unloading, adjustment, adhesive application, and loading of the mandrel A at each station, which has a high degree of automation and is conducive to improving production efficiency.

[0066] It should be noted that the loading station is not essential, and in some embodiments, it may be omitted. That is, the transfer device 10 transfers the mandrel A to the adhesive application station B3, and the adhesive application device 40 applies adhesive to the mandrel A. Then, the loading device 50 directly clamps the mandrel A located at the adhesive application station B3 and transfers the clamped mandrel A to the winding mechanism D.

[0067] In a specific embodiment, the mandrel feeding device also includes a mounting plate 60, on which the transfer device 10, the unloading device 20, the adjustment device 30, the adhesive application device 40, and the feeding device 50 are all mounted to improve the integration of the device, facilitate maintenance, and reduce the space required.

[0068] In an embodiment of the present invention, the transfer device 10 includes two transfer mechanisms 13. One transfer mechanism 13 is movable between the unloading station B1 and the adjustment station B2 to receive the mandrel A output by the unloading device 20 at the unloading station B1 and transfer the mandrel A to the adjustment device 30 at the adjustment station B2. The other transfer mechanism 13 is movable between the adjustment station B2 and subsequent stations (i.e., the adhesive application station B3 and the loading station) to receive the mandrel A transferred by the adjustment device 30 at the adjustment station B2, allow the adhesive application device 40 to apply adhesive to the mandrel A at the adhesive application station B3, and transfer the mandrel A to the loading device 50 at the loading station.

[0069] For ease of description, the transfer mechanism 13 that moves between the unloading station B1 and the adjustment station B2 is named the first transfer mechanism 13a, and the transfer mechanism 13 that moves between the adjustment station B2, the adhesive application station B3, and the loading station is named the second transfer mechanism 13b. During actual material loading, the first transfer mechanism 13a moves to the unloading station B1 and receives the mandrel A output by the unloading device 20. Then, the first transfer mechanism 13a moves to the adjustment station B2, causing the adjustment device 30 to pick up the mandrel A from the first transfer mechanism 13a and rotate the mandrel A until the positioning part a1 on the mandrel A is in a preset position. Simultaneously, the first transfer mechanism 13a returns from the adjustment station B2 to the unloading station B1 to receive the next mandrel A output by the unloading device 20, and the second transfer mechanism 13b moves to the adjustment station B2. Then, the adjusting device 30 transfers the adjusted mandrel A to the second transfer mechanism 13b, which carries the adjusted mandrel A to the adhesive application station B3. Next, the adhesive application device 40 applies double-sided adhesive layer a2 to the mandrel A on the second transfer mechanism 13b. Then, the second transfer mechanism 13b carries the adhesive-applied mandrel A to the loading station, where the loading device 50 picks up the mandrel A from the second transfer mechanism 13b and transfers it to the winding mechanism D. At this point, the second transfer mechanism 13b can return to the adjusting station to receive the next adjusted mandrel A.

[0070] It is understandable that the process of the first transfer mechanism 13a transferring the mandrel A between the unloading station B1 and the adjustment station B2 can be carried out simultaneously with the process of the second transfer mechanism 13b transferring the mandrel A between the adjustment station B2, the adhesive application station B3 and the loading station, thereby greatly improving the loading efficiency of the mandrel A.

[0071] Please see Figure 4As shown, in some embodiments, the transfer device 10 further includes a base 110 and a first transfer drive mechanism (not shown) and a second transfer drive mechanism (not shown) disposed on the base 110. The base 110 is fixedly mounted on the mounting plate 60. The first transfer mechanism 13a and the second transfer mechanism 13b are both movably connected to the base 110 along the first direction X, and are respectively driven by the first transfer drive mechanism and the second transfer drive mechanism, such that the first transfer drive mechanism drives the first transfer mechanism 13a to move between the unloading station B1 and the adjustment station B2; the second transfer drive mechanism drives the second transfer mechanism 13b to move between the adjustment station B2, the adhesive application station B3, and the loading station.

[0072] Optionally, the first transfer drive mechanism includes a drive cylinder 115, which is mounted on the base 110. The telescopic end of the drive cylinder 115 is connected to the first transfer mechanism 13a, thereby driving the first transfer mechanism 13a to move along the first direction X between the unloading station B1 and the adjustment station B2. Of course, in other embodiments, the first transfer drive mechanism may also use other linear drive modules, as long as they can drive the first transfer mechanism 13a to move along the first direction X between the unloading station B1 and the adjustment station B2. This is not limited here.

[0073] Optionally, the second transfer drive mechanism includes a first lead screw 112, a transfer drive component 111, and a first lead screw nut 113. The first lead screw 112 is rotatably connected to the base 110 about its own axis, and the axis of the first lead screw 112 is parallel to the first direction X. The transfer drive component 111 is mounted on the base 110 and is drivenly connected to the first lead screw 112 to drive the first lead screw 112 to rotate about its own axis. The first lead screw nut 113 is threadedly connected to the first lead screw 112 and fixedly connected to the second transfer mechanism 13b, so that the first lead screw nut 113 and the second transfer mechanism 13b move together along the first direction X. Thus, when the transfer drive component 111 drives the first lead screw 112 to rotate, the first lead screw nut 113 moves along the axis of the first lead screw 112 (i.e., the first direction X), thereby driving the second transfer mechanism 13b to move along the first direction X between the adjustment station B2, the adhesive application station B3, and the loading station. Optionally, the transfer drive component 111 can be a motor. Of course, in other embodiments, the second transfer drive mechanism may also adopt other linear drive modules, as long as it can drive the second transfer mechanism 13b to move between the adjustment station B2, the adhesive application station B3 and the material loading station along the first direction X, which is not limited here.

[0074] Please see Figure 5 and Figure 6As shown, in an embodiment of the present invention, the transfer mechanism 13 includes a mounting base 130, a tray 132, and a clamping structure 136. The mounting base 130 is movably connected to the base 110 along a first direction X and is connected to a first transfer drive mechanism or a second transfer drive mechanism, so as to be driven by the first transfer drive mechanism or the second transfer drive mechanism to move along the first direction X. The tray 132 is mounted on the mounting base 130 and is used to receive the mandrel A. The clamping structure 136 is used to clamp or release the mandrel A carried on the tray 132. Specifically, the clamping structure 136 includes two clamping blocks 131, which are disposed on the mounting base 130 and located on both sides of the tray 132 in the first direction X (in Figure 6 In the illustrated embodiment, two clamping blocks 131 are located on the left and right sides of the tray 132, respectively. The two clamping blocks 131 can be controlled to move closer or further apart to clamp or release the mandrel A supported on the tray 132. Thus, at the unloading station B1, the mandrel A output by the unloading device 20 is unloaded onto the tray 132 of the first transfer mechanism 13a, and then the two clamping blocks 131 of the first transfer mechanism 13a are controlled to move closer together until the mandrel A on the tray 132 is clamped. At the adjustment station B2, the adjustment device 30 places the adjusted mandrel A onto the tray 132 of the second transfer mechanism 13b, and then controls the two clamping blocks 131 of the second transfer mechanism 13b to move closer together until the mandrel A on the tray 132 is clamped.

[0075] Optionally, there can be multiple clamping structures 136, which are spaced apart along a second direction Y perpendicular to the first direction X. When the mandrel A is supported on the support plate 132, the longitudinal direction of the mandrel A is parallel to the second direction Y. Thus, by simultaneously clamping the mandrel A with multiple clamping structures 136 spaced apart along the longitudinal direction of the mandrel A, the clamping of the mandrel A becomes more stable. Specifically... Figure 6 In the embodiment shown, there are two clamping structures 136.

[0076] Optionally, the base 110 is provided with a first slide rail 114 extending longitudinally along the first direction X (see...). Figure 4 Each of the two transfer mechanisms 13 has a first slider (not shown) on its mounting base 130. Each first slider is slidably engaged with a first slide rail 114, thereby guiding the movement of the two transfer mechanisms 13 in the first direction X by the movement of the two first sliders along the first slide rail 114.

[0077] Please see Figures 7 to 12As shown, in a specific embodiment, the clamping structure 136 further includes a first elastic element 134 and a wedge block 138 both disposed on the mounting base 130. Each of the two clamping blocks 131 is correspondingly provided with a first elastic element 134, and each first elastic element 134 abuts against its corresponding clamping block 131 to provide a preload force that causes the two clamping blocks 131 to tend to move closer to each other. Each clamping block 131 has an abutment portion 1314. The wedge block 138 is disposed on the mounting base 130 and has a first side surface 1380 and a second side surface 1382 facing away from each other in a first direction X. The abutment portions 1314 on the two clamping blocks 131 abut against the first side surface 1380 and the second side surface 1382 of the wedge block 138, respectively. The wedge block 138 can be controllably reciprocated along a second direction Y, and the distance between the first side surface 1380 and the second side surface 1382 is set to gradually increase or decrease in the second direction Y, which is perpendicular to the first direction X. Thus, as the distance between the first side 1380 and the second side 1382 gradually increases or decreases in the second direction Y, during the movement of the wedge block 138 along the second direction Y, under the combined action of the first elastic elements 134 and the wedge block 138, the two clamping blocks 131 can be moved closer or further apart, thereby clamping or releasing the mandrel A on the support plate 132. Optionally, the first elastic element 134 can be a spring.

[0078] Optionally, both abutment portions 1314 are rollers, and the rollers on the two clamping blocks 131 can roll along the first side surface 1380 and the second side surface 1382, respectively. In this way, setting both abutment portions 1314 as rollers helps to reduce the friction between the abutment portions 1314 and the wedge block 138, reduce wear, and extend service life; on the other hand, it helps to improve the flexibility of movement of the wedge block 138.

[0079] Furthermore, the clamping structure 136 also includes a movable drive member 137 disposed on the mounting base 130. The movable drive member 137 is connected to the wedge block 138, enabling the movable drive member 137 to drive the wedge block 138 to reciprocate along the second direction Y. Optionally, the movable drive member 137 may be a cylinder.

[0080] Specifically, in this embodiment, the clamping structure 136 further includes two fixing blocks 133 and a guide rod 135. The two fixing blocks 133 are fixedly connected to the mounting base 130 at intervals along a first direction X, and the support plate 132 is located between the two fixing blocks 133. The two ends of the guide rod 135 are respectively connected to the two fixing blocks 133. Two clamping blocks 131 are slidably connected to the guide rod 135, allowing the two clamping blocks 131 to move closer or further apart along the guide rod 135. One first elastic member 134 abuts against one of the fixing blocks 133 and an adjacent clamping block 131, and the other first elastic member 134 abuts against another fixing block 133 and an adjacent clamping block 131. It should be noted that the number of guide rods 135 can be two or more, thereby simultaneously guiding the movement of the clamping blocks 131 using each guide rod 135, making the movement of the clamping blocks 131 more stable and reliable.

[0081] Optionally, both clamping blocks 131 have clamping portions 1311, which are arranged opposite each other in the first direction X, and each has a clamping ramp 1313 on its facing side. The two clamping portions 1311 clamp or release the mandrel A on the support plate 132 via their respective clamping ramps 1313. The distance between the two clamping ramps 1313 is set to gradually decrease from the end closer to the support plate 132 to the end farther from the support plate 132 (i.e., as shown in the image). Figure 5 The distance between the two clamping ramps 1313 shown gradually decreases from bottom to top, so that when the two clamping parts 1311 clamp the mandrel A on the support plate 132 between the two clamping ramps 1313, the clamping force applied to the mandrel A has a component force toward the support plate 132 (i.e., as shown in the figure). Figure 5 The downward component force shown in the figure makes the mandrel A clamped and pressed firmly against the support plate 132, thus making the clamping of the mandrel A more stable.

[0082] Furthermore, the pallet 132 has a positioning groove (not shown) for positioning the mandrel A, which extends longitudinally along a second direction Y perpendicular to the first direction X. Thus, when the mandrel A is placed onto the pallet 132, it is accommodated within the positioning groove, thereby positioning the mandrel A in the first direction X and preventing it from rolling freely before being clamped by the two clamping blocks 131.

[0083] In a specific embodiment, the transfer mechanism 13 further includes a fixing and positioning member 141 connected to the mounting base 130. This fixing and positioning member 141 is located at one end of the positioning groove in the second direction Y, and is used to abut against one end of the mandrel A located within the positioning groove, thereby positioning the mandrel A in the second direction Y. See also... Figure 14As shown, the transfer device 10 also includes a positioning mechanism 14 disposed at the unloading station B1, which includes a movable positioning member 142. When the transfer mechanism 13 moves to the unloading station B1, the movable positioning member 142 is located at the other end of the positioning groove (that is, at this time, the movable positioning member 142 and the fixed positioning member 141 are respectively located at the two ends of the positioning groove in the second direction Y), and the movable positioning member 142 can be controlled to move closer to or further away from the fixed positioning member 141 along the second direction Y, so as to clamp or release the mandrel A in the positioning groove together with the fixed positioning member 141 along the second direction Y. Thus, when the transfer mechanism 13 moves to the unloading station B1, firstly, the mandrel A output by the unloading device 20 falls into the positioning groove of the support plate 132 of the transfer mechanism 13. Then, the movable positioning member 142 moves closer to the fixed positioning member 141 along the second direction Y until it presses the mandrel A in the positioning groove against the fixed positioning member 141 (i.e., at this time, the movable positioning member 142 and the fixed positioning member 141 together clamp the mandrel A in the positioning groove). Next, the movable positioning member 142 moves away from the fixed positioning member 141 along the second direction Y until it returns to its initial position, thus completing the positioning of the mandrel A in the positioning groove in the second direction Y. Then, the two clamping blocks 131 move closer to each other until they clamp the mandrel A in the positioning groove.

[0084] Furthermore, the positioning mechanism 14 also includes a positioning drive 144, a connecting block 143, and a buffer elastic member 146. The positioning drive 144 is mounted on the mounting plate 60, and the connecting block 143 is mounted on the drive end of the positioning drive 144 so as to be driven by the positioning drive 144 to reciprocate along the second direction Y. The movable positioning member 142 is movably connected to the connecting block 143 along the second direction Y. The buffer elastic member 146 abuts between the connecting block 143 and the movable positioning member 142 to provide a preload force that causes the movable positioning member 142 to have a tendency to move away from the connecting block 143 along the second direction Y. Thus, when it is necessary to position the mandrel A in the positioning groove, the positioning drive 144 drives the movable connecting block 143 to move along the second direction Y towards the fixed positioning member 141, so that the movable positioning member 142 pushes the mandrel A in the positioning groove toward the fixed positioning member 141 until the mandrel A in the positioning groove is pressed tightly onto the fixed positioning member 141. At this time, the buffer elastic member 146 is compressed and plays a buffering role, preventing the movable positioning member 142 and the fixed positioning member 141 from damaging the mandrel A. Optionally, the buffer elastic member 146 can be a spring, and the positioning drive 144 can be a cylinder.

[0085] Please see Figures 13 to 15As shown, in an embodiment of the present invention, the feeding device 20 includes a material box 21 and a feeding wheel 22. The material box 21 has a receiving cavity 210 and an opening 212. The receiving cavity 210 is used to receive a plurality of mandrels A, and the opening 212 is located at the bottom of the receiving cavity 210. The feeding wheel 22 is rotatably disposed below the material box 21. A plurality of receiving grooves 221 are formed on the peripheral surface of the feeding wheel 22. The plurality of receiving grooves 221 are arranged at intervals along the circumference of the feeding wheel 22, such that each receiving groove 221 passes through the opening 212 one by one during the rotation of the feeding wheel 22. Each receiving groove 221 is used to receive a mandrel A when it rotates with the feeding wheel 22 to the opening 212, and when it rotates with the feeding wheel 22 to the discharge position, it transfers the mandrel A to the support plate 132 of the first transfer mechanism 13a of the transfer device 10.

[0086] In actual use, the discharge wheel 22 rotates, causing the various receiving grooves 221 on the discharge wheel 22 to rotate along with it. When the receiving groove 221 rotates past the opening 212, the mandrel A in the receiving cavity 210 enters the receiving groove 221 through the opening 212 and leaves the opening 212 along with the receiving groove 221. When the receiving groove 221 containing the mandrel A rotates to the discharge position, the mandrel A in the receiving groove 221 falls onto the pallet 132 of the first transfer mechanism 13a at the discharge station B1 under its own gravity.

[0087] In this way, the rotation of the dropping wheel 22 continuously drives each receiving tank 221 to pick up the mandrel A at the opening 212 and output the mandrel A at the discharge position, so that the transfer mechanism 13 can transfer the mandrel A from the dropping station B1 to the adjustment station B2 one by one. That is, the rotation of the dropping wheel 22 realizes the continuous dropping of the mandrel A, which is beneficial to improving the feeding efficiency of the mandrel A.

[0088] Optionally, the opening 212 is located at the top of the discharge wheel 22, so that the mandrel A in the receiving cavity 210 can fall into the receiving groove 221 reaching the opening 212 under its own gravity. The discharge position is located at the bottom of the discharge wheel 22, so that the mandrel A that rotates to the receiving groove 221 at the bottom of the discharge plate 22 can fall onto the support plate 132 of the first transfer mechanism 13a under its own gravity.

[0089] In a specific embodiment, the unloading device 20 further includes a guide member 23, which is arranged around the unloading wheel 22 and forms a conveying channel (not shown) with the peripheral surface of the unloading wheel 22. This allows the mandrel A, housed in the receiving groove 221, to move along the conveying channel with the unloading wheel 22 during its rotation, preventing the mandrel A from falling out of the receiving groove 221 before reaching the discharge position. The guide member 23 has an inlet end 2210 located at the opening 212 and a discharge end 2212 located at the discharge position. During the rotation of the unloading wheel 22, the mandrel A housed in the receiving groove 221 enters the conveying channel from the inlet end 2210 and is conveyed from the discharge end 2212 to the pallet 132 of the transfer mechanism 13 that reaches the unloading station B1.

[0090] Thus, the guide 23 prevents the mandrel A in the receiving groove 221 from falling before it reaches the discharge position as it rotates with the discharge wheel 22, so that the mandrel A in each receiving groove 221 can smoothly rotate with the discharge wheel 22 to reach the discharge position and be transported to the tray 132 of the transfer mechanism 13 that reaches the discharge station B1.

[0091] It should be noted that the method of preventing mandrel A from falling before it reaches the discharge position is not limited to using guide member 23. In other embodiments, magnetic attraction or clamping can also be used to fix mandrel A in the receiving groove 221, and release mandrel A when it reaches the discharge position, thereby ensuring that mandrel A can smoothly reach the discharge position and fall onto the tray 132 of transfer mechanism 13 at the discharge position.

[0092] In a specific embodiment, the unloading device 20 further includes a guide fitting 24 disposed at the discharge position. The guide fitting 24 and the discharge end 2212 of the guide member 23 form a discharge port C. When the mandrel A, housed in the receiving groove 221, reaches the discharge port C as the unloading wheel 22 rotates, it falls from the discharge port C onto the support plate 132 of the transfer mechanism 13 under its own gravity. Thus, by utilizing the discharge port C formed between the discharge end 2212 of the guide member 23 and the guide fitting 24, the unloading position of the mandrel A is defined, ensuring that the mandrel A can accurately fall into the positioning groove on the support plate 132 of the transfer mechanism 13.

[0093] Furthermore, the material feeding device 20 also includes a mounting frame 25 and a material feeding drive component 26. The mounting frame 25 is fixedly connected to the mounting plate 60, the material box 21 is fixedly connected to the mounting frame 25, and the material feeding wheel 22 is rotatably connected to the mounting frame 25. The material feeding drive component 26 is mounted on the mounting frame 25 and connected to the material feeding wheel 22, so that the material feeding drive component 26 can drive the material feeding wheel 22 to rotate. The aforementioned guide component 23 and guide mating component 24 are both mounted on the mounting frame 25. Optionally, the material feeding drive component 26 can be a motor.

[0094] Please see Figure 16 As shown, in an embodiment of the present invention, the adjustment device 30 includes an adjustment mechanism 32. The adjustment mechanism 32 includes a first support base 320 and a first rotating abutment shaft 321 and a second rotating abutment shaft 322, both rotatably connected to the first support base 320 about their own axes. The first support base 320 is fixedly connected to the mounting plate 60. The axes of the first rotating abutment shaft 321 and the second rotating abutment shaft 322 are collinear (i.e., the first rotating abutment shaft 321 and the second rotating abutment shaft 322 are coaxial). The first rotating abutment shaft 321 and the second rotating abutment shaft 322 are spaced apart from each other. The mandrel A, transferred to the adjustment station by the transfer device 10, can be controllably moved between the first rotating abutment shaft 321 and the second rotating abutment shaft 322. The first rotating abutment shaft 321 and the second rotating abutment shaft 322 can be controllably moved closer to or further away from each other to clamp or release the mandrel A located between the first rotating abutment shaft 321 and the second rotating abutment shaft 322. Optionally, the axes of the first rotating abutment shaft 321 and the second rotating abutment shaft 322 are both parallel to the second direction Y, and the first rotating abutment shaft 321 and the second rotating abutment shaft 322 are arranged at intervals along the second direction Y.

[0095] The adjustment mechanism 32 also includes a detection element 324, which is used to detect the position of the positioning part a1 on the mandrel A clamped between the first rotating abutment shaft 321 and the second rotating abutment shaft 322. Optionally, the detection element 324 may be a through-beam photoelectric sensor.

[0096] Specifically, in this embodiment, the adjustment device 30 further includes a clamping mechanism 31, which includes a clamping component 312. This clamping component 312 is movable along a third direction Z to both the material picking position and the adjustment position. This third direction Z intersects both the first direction X and the second direction Y. Preferably, the third direction Z is perpendicular to both the first direction X and the second direction Y. When the clamping component 312 moves to the material picking position, it can clamp the mandrel A on the first transfer mechanism 13a that has reached the adjustment station B2, or place the mandrel A on the second transfer mechanism 13b that has reached the adjustment station B2. When the clamping assembly 312 moves to the adjustment station B2, the mandrel A clamped by the clamping assembly 312 reaches between the first rotating abutment shaft 321 and the second rotating abutment shaft 322, so that the first rotating abutment shaft 321 and the second rotating abutment shaft 322 can approach each other to abut against the two ends of the mandrel A respectively, that is, the first rotating abutment shaft 321 and the second rotating abutment shaft 322 clamp the mandrel A along the second direction Y (i.e., the axial direction of the mandrel A).

[0097] Thus, when the first transfer mechanism 13a moves to the adjustment station B2, firstly, the clamping assembly 312 moves closer to the first transfer mechanism 13a along the third direction Z until it reaches the material picking position. At this time, the clamping assembly 312 clamps the mandrel A on the first transfer mechanism 13a, and the clamping structure 136 of the first transfer mechanism 13a releases its grip on the mandrel A. Then, the clamping assembly 312 moves away from the first transfer mechanism 13a along the third direction Z until it reaches the adjustment position. At this time, the mandrel A clamped by the clamping assembly 312 is located between the first rotating abutment shaft 321 and the second rotating abutment shaft 322. The first transfer mechanism 13a can return from the adjustment station B2 to the unloading station B1, and the second transfer mechanism 13b can move to the adjustment station B2. Then, the first rotating abutment shaft 321 and the second rotating abutment shaft 322 move closer to each other until they respectively abut against both ends of the longitudinal length of the mandrel A (i.e., clamp the mandrel A along the second direction Y). At this point, the clamping assembly 312 releases the mandrel A, and the first rotating abutment shaft 321 and the second rotating abutment shaft 322 drive the mandrel A to rotate. When the detection element 324 detects that the positioning part a1 on the mandrel A has reached the preset position, the first rotating abutment shaft 321 and the second rotating abutment shaft 322 stop rotating, thus completing the adjustment of the mandrel A. Then, the clamping assembly 312 clamps the mandrel A again, and the first rotating abutment shaft 321 and the second rotating abutment shaft 322 move away from each other, releasing the mandrel A. Then, the clamping assembly 312 moves towards the second transfer mechanism 13b along the third direction Z until the mandrel A is placed on the support plate 132 of the second transfer mechanism 13b and clamped by the clamping structure 136. Then, the clamping assembly 312 releases the mandrel A and returns away from the second transfer mechanism 13b along the third direction Z. At this time, the second transfer mechanism 13b can move from the adjustment station B2 to the adhesive application station B3.

[0098] It should be noted that the position of the mandrel A between the first rotating abutment shaft 321 and the second rotating abutment shaft 322 is not limited to using the clamping mechanism 31. In other embodiments, a transfer mechanism 13 with lifting function can also be used, that is, the position of the mandrel A between the first rotating abutment shaft 321 and the second rotating abutment shaft 322 is achieved by the lifting of the transfer mechanism 13 itself, which is not limited here.

[0099] In a specific embodiment, the adjustment mechanism 32 further includes a guide shaft 323 connected to one end of the first rotating abutment shaft 321 facing the second rotating abutment shaft 322. As the first rotating abutment shaft 321 and the second rotating abutment shaft 322 move closer or further apart, the guide shaft 323 inserts into or retracts from the central hole of the mandrel A located between the first rotating abutment shaft 321 and the second rotating abutment shaft 322. Thus, when the clamping assembly 312 clamps the mandrel A to the adjustment position, the first rotating abutment shaft 321 and the second rotating abutment shaft 322 move closer together, causing the guide shaft 323 to insert into the central hole of the mandrel A and guide the mandrel A until the first rotating abutment shaft 321 and the second rotating abutment shaft 322 respectively abut against the two longitudinal ends of the mandrel A, thereby clamping the mandrel A.

[0100] Of course, in other embodiments, the guide shaft 323 can also be connected to the end of the second rotating abutment shaft 322 facing the first rotating abutment shaft 321, which can also play the role of guiding the mandrel A. This is not limited here.

[0101] Please see Figures 17 to 18 As shown, in a specific embodiment, the adjustment mechanism 32 further includes a first movable seat 325 and a first driving member 326. The first movable seat 325 is movably connected to the first support seat 320 along the second direction Y. The first rotating abutment shaft 321 is rotatably connected to the first movable seat 325 about its own axis, thereby enabling the first movable seat 325 to drive the first rotating abutment shaft 321 to move along the second direction Y. The first driving member 326 is mounted on the first support seat 320 and connected to the first movable seat 325, enabling the first driving member 326 to drive the first movable seat 325 to move relative to the first support seat 320 along the second direction Y, causing the first movable seat 325 to drive the first rotating abutment shaft 321 closer to or away from the second rotating abutment shaft 322. Optionally, the first driving member 326 may be a cylinder.

[0102] Optionally, the first support base 320 is provided with a second slide rail 3202 extending longitudinally along the second direction Y, and the first movable base 325 is provided with a second slider 3203 that slides in cooperation with the second slide rail 3202. In this way, the movement of the second slider 3203 along the second slide rail 3202 guides the movement of the first movable base 325 relative to the first support base 320 along the second direction Y.

[0103] Optionally, the first rotating abutment shaft 321 is mounted on the first movable seat 325 via a bearing, thereby enabling the first rotating abutment shaft 321 to rotate relative to the first movable seat 325.

[0104] In a specific embodiment, the adjustment mechanism 32 further includes a second movable seat 328 and a second driving member 329. The second movable seat 328 is movably connected to the first support seat 320 along the second direction Y. The second rotating abutment shaft 322 is rotatably connected to the second movable seat 328 about its own axis, so that the second rotating abutment shaft 322 can move along the second direction Y under the drive of the second movable seat 328. The second driving member 329 is mounted on the first support seat 320 and connected to the second movable seat 328, so that the second driving member 329 can drive the second movable seat 328 to move relative to the first support seat 320 along the second direction Y, thereby causing the second movable seat 328 to drive the second rotating abutment shaft 322 closer to or away from the first rotating abutment shaft 321. Optionally, the second driving member 329 can be a cylinder.

[0105] Optionally, the first support 320 is provided with a third slide rail 3201 extending longitudinally along the second direction Y, and the second movable seat 328 is provided with a third slider that slides in cooperation with the third slide rail 3201. In this way, the movement of the third slider along the third slide rail 3201 guides the movement of the second movable seat 328 relative to the first support 320 along the second direction Y.

[0106] Optionally, the second rotating abutment shaft 322 is mounted on the second movable seat 328 via a bearing, thereby enabling the second rotating abutment shaft 322 to rotate relative to the second movable seat 328.

[0107] Specifically, the adjustment mechanism 32 further includes a first rotary drive member 327 mounted on the first movable seat 325. The first rotary drive member 327 is connected to the first rotary abutment shaft 321, enabling the first rotary drive member 327 to drive the first rotary abutment shaft 321 to rotate, thereby causing the mandrel A, which is clamped by the first rotary abutment shaft 321 and the second rotary abutment shaft 322, to rotate. Further, the output shaft of the first rotary drive member 327 is connected to the first rotary abutment shaft 321 via a belt drive structure 3271, so that the rotational motion output by the first rotary drive member 327 is transmitted to the first rotary abutment shaft 321 via the belt drive structure 3271, thereby driving the first rotary abutment shaft 321 to rotate.

[0108] Of course, in another embodiment, the first rotary drive 327 may also be mounted on the second movable seat 328. The first rotary drive 327 is connected to the second rotary abutment shaft 322, so that the first rotary drive 327 can drive the second rotary abutment shaft 322 to rotate, thereby driving the mandrel clamped by the first rotary abutment shaft 321 and the second rotary abutment shaft 322 to rotate.

[0109] In some embodiments, the adjustment mechanism 32 further includes an adjustment seat (not shown) disposed on the first support 320, on which the detection element 324 is mounted. The position of the adjustment seat relative to the first support 320 is adjustable, thereby achieving the purpose of adjusting the position of the detection element 324. Optionally, the position of the adjustment seat relative to the first support 320 is adjustable along the second direction Y and / or the third direction Z. Thus, by adjusting the position of the adjustment seat relative to the first support 320 along the second direction Y and / or the third direction Z, the position of the detection element 324 in the second direction Y and / or the third direction Z is adjusted, thereby enabling the use of mandrels A of different specifications and improving the compatibility of the device.

[0110] Further, the adjusting seat includes a first adjusting block 3241, a first threaded locking member, a second adjusting block 3242, and a second threaded locking member. The first adjusting block 3241 has a first oblong hole 3243 extending longitudinally along a second direction Y. The first threaded locking member passes through the first oblong hole 3243 and is threadedly connected to the first support seat 320 to secure the first adjusting block 3241 to the first support seat 320. The second adjusting block 3242 has a second oblong hole 3244 extending longitudinally along a third direction Z. The second threaded locking member passes through the second oblong hole 3244 and is threadedly connected to the first adjusting block 3241 to secure the second adjusting block 3242 to the first adjusting block 3241. A detection member 324 is installed on the second adjusting block 3242 to adjust its position along with the second adjusting block 3242. Optionally, both the first and second threaded locking components can be locking screws.

[0111] Thus, when it is necessary to adjust the position of the detection element 324 in the second direction Y, first loosen the first threaded locking member and push the first adjusting block 3241 to move relative to the first support base 320 along the second direction Y, thereby driving the second adjusting block 3242 and the detection element 324 to move along the second direction Y. After the position of the detection element 324 in the second direction Y is adjusted to the correct position, tighten the first threaded locking member to lock the first adjusting block 3241 onto the first support base 320.

[0112] When it is necessary to adjust the position of the detection element 324 in the third direction Z, first loosen the second threaded locking member and push the second adjusting block 3242 to move relative to the first adjusting block 3241 in the third direction Z, thereby causing the detection element 324 to move in the third direction Z. After the position of the detection element 324 in the third direction Z is adjusted to the correct position, tighten the second threaded locking member to lock the second adjusting block 3242 onto the first adjusting block 3241.

[0113] Please see Figure 19 and Figure 20 As shown, in some embodiments, the clamping mechanism 31 further includes a second driving assembly, which comprises a second support base 310, a third movable base 311, and a third driving member 313. The second support base 310 is fixedly connected to the mounting plate 60, and the third movable base 311 is movably connected to the second support base 310 along a third direction Z. The clamping assembly 312 is mounted on the third movable base 311, so that the clamping assembly 312 moves along the third direction Z along with the third movable base 311. The third driving member 313 is disposed on the second support base 310 and connected to the third movable base 311, so that the third driving member 313 can drive the third movable base 311 to move relative to the second support base 310 along the third direction Z, and drive the clamping assembly 312 to move to the material picking position or adjustment position. When the clamping assembly 312 moves to the adjustment position, the mandrel A on the clamping assembly 312 is located between the first rotating abutment shaft 321 and the second rotating abutment shaft 322, and is coaxial with the first rotating abutment shaft 321 and the second rotating abutment shaft 322. This ensures that when the first rotating abutment shaft 321 and the second rotating abutment shaft 322 clamp the mandrel A and drive the mandrel A to rotate, the rotation of the first rotating abutment shaft 321, the second rotating abutment shaft 322, and the mandrel A is smooth and stable.

[0114] Optionally, the second drive assembly further includes a second lead screw 314 and a second lead screw nut 315. The second lead screw 314 is rotatably connected to the second support 310 about its own axis, and the axis of the second lead screw 314 is parallel to the third direction Z. A third drive member 313 is connected to the second lead screw 314, enabling the third drive member 313 to drive the second lead screw 314 to rotate about its own axis. The second lead screw nut 315 is threadedly connected to the second lead screw 314 and fixedly connected to the third movable seat 311, allowing the third movable seat 311 to move together with the second lead screw nut 315. Thus, when the third driving member 313 drives the second lead screw 314 to rotate, the second lead screw nut 315 moves along the third direction Z (i.e., the axial direction of the second lead screw 314), thereby driving the third moving seat 311 and the clamping assembly 312 to move along the third direction Z between the material picking position and the adjustment position, thereby ensuring that when the clamping assembly 312 reaches the adjustment position, the mandrel A on the clamping assembly 312 is coaxial with the first rotating abutment shaft 321 and the second rotating abutment shaft 322. Optionally, the third driving member 313 can be a motor.

[0115] Optionally, the second support 310 is provided with two guide rods 316 that extend longitudinally along the third direction Z, and the third movable seat 311 is slidably disposed on the two guide rods 316. In this way, the two guide rods 316 guide the movement of the third movable seat 311 relative to the second support 310 along the third direction Z.

[0116] In a specific embodiment, the gripping assembly 312 includes a gripper cylinder (not shown) and two grippers (not shown) mounted on the drive end of the gripper cylinder. The gripper cylinder drives the two grippers to move closer or further apart, so that the two grippers clamp or release the mandrel. Of course, in other embodiments, the gripping assembly 312 may also adopt other gripper structures, as long as they can clamp or release the mandrel, and this is not limited here.

[0117] Please see Figure 21 and Figure 22As shown, in an embodiment of the present invention, the adhesive applicator 40 includes a motion mechanism 41, an unwinding mechanism 43, a winding mechanism 44, an adhesive applicator 45, and a cutting mechanism 46. The motion mechanism 41 includes a first drive assembly 411 and a transfer seat 412 pulverizedly connected to the first drive assembly 411. The first drive assembly 411 drives the transfer seat 412 to move along a second direction Y and a third direction Z. The second direction Y intersects with the third direction Z; preferably, the third direction Z is perpendicular to the second direction Y. The unwinding mechanism 43 is disposed on the transfer seat 412 and is used to unwind double-sided adhesive tape a3, which includes a double-sided adhesive layer a2 and a release film a4 stacked together. The winding mechanism 44 is disposed on the transfer seat 412 and is used to wind the release film a4 of the double-sided adhesive tape a3. The adhesive applicator 45 is disposed on the transfer seat 412 and has an adhesive applicator wheel 451 through which the double-sided adhesive tape a3 is wound. The cutting mechanism 46 is mounted on the transfer seat 412 and is used to cut the double-sided adhesive layer a2 of the double-sided tape a3 by the upstream side of the adhesive roller 451, so that the release film a4 of the double-sided tape a3 remains continuous and is eventually wound up by the winding mechanism 44.

[0118] During the movement of the transfer seat 412 along the third direction Z, it can drive the adhesive roller 451 to press the double-sided adhesive layer a2 against the mandrel A on the transfer mechanism 13 that has reached the adhesive application station. During the movement of the transfer seat 412 along the second direction Y, it can drive the adhesive roller 451 to roll along the surface of the mandrel A on the transfer mechanism 13, so as to stick the double-sided adhesive layer a2 onto the mandrel A on the transfer mechanism 13.

[0119] In the actual adhesive application process, when the transfer mechanism 13, carrying the mandrel A, moves from the adjustment station B2 to the adhesive application station B3, the transfer seat 412 first moves closer to the mandrel A on the transfer mechanism 13 along the third direction Z until the adhesive application wheel 451 presses the double-sided adhesive tape a3 against the mandrel A. At this time, the double-sided adhesive layer a2 of the double-sided adhesive tape a3 is in contact with the surface of the mandrel A, and the release film a4 of the double-sided adhesive tape a3 is located between the double-sided adhesive layer a2 and the adhesive application wheel 451. Then, the transfer seat 412 moves a preset distance along the second direction Y (i.e., the axial direction of the mandrel A) (at the same time, the winding mechanism 44 winds up the release film a4, and the unwinding mechanism 43 unwinds the double-sided adhesive tape a3), thereby causing the adhesive application wheel 451 to roll along the surface of the mandrel A to adhere the double-sided adhesive layer a2 to the mandrel A. Next, the cutting mechanism 46 cuts the double-sided adhesive layer a2 of the double-sided tape a3 from the upstream side of the adhesive roller 451 (without cutting the release film a4 of the double-sided tape a3), at which point the cut double-sided adhesive layer a2 is adhered to the mandrel A. Then, the transfer seat 412 moves away from the mandrel A on the transfer mechanism 13 along the third direction Z and returns to the initial position, preparing for the next adhesive application action. In this way, the above-mentioned adhesive application device 40 can realize automatic and continuous adhesive application action, with a high degree of automation and stable and reliable adhesive application process, which is conducive to improving adhesive application efficiency and the stability of adhesive application quality.

[0120] It should be noted that the upstream side of the aforementioned adhesive roller 451 is relative to the conveying of the double-sided tape a3, that is, the position that the double-sided tape a3 passes through first is the upstream position, and the position that it passes through later is the downstream position.

[0121] Specifically, in this embodiment, the first driving assembly 411 includes a base 4110, a motion seat 4112, a first motion driving member 4113, and a second motion driving member 4114. The base 4110 is fixedly mounted on the mounting plate 60. The motion seat 4112 is movably connected to the base 4110 along a second direction Y, and the transfer seat 412 is movably connected to the motion seat 4112 along a third direction Z. The first motion driving member 4113 is disposed on the base 4110 and is drivenly connected to the motion seat 4112 to drive the motion seat 4112 to move relative to the base 4110 along the second direction Y. The second motion driving member 4114 is disposed on the motion seat 4112 and is drivenly connected to the transfer seat 412 to drive the transfer seat 412 to move relative to the motion seat 4112 along a third direction Z. Thus, when it is necessary to move the adhesive-applying wheel 451 along the third direction Z so that the adhesive-applying wheel 451 abuts against or separates from the mandrel A on the transfer mechanism 13, the second motion drive 4114 can be used to drive the transfer seat 412 to move relative to the motion seat 4112 along the third direction Z. When it is necessary to move the adhesive-applying wheel 451 along the second direction Y so that the adhesive-applying wheel 451 rolls along the axial direction of the mandrel, the first motion drive 4113 can be used to drive the motion seat 4112 to move along the second direction Y, thereby driving the adhesive-applying wheel 451 to roll along the axial direction of the mandrel, so that the adhesive-applying wheel 451 adheres the double-sided adhesive layer a2 to the mandrel A.

[0122] Optionally, the first motion drive member 4113 and the second motion drive member 4114 can be a lead screw drive structure. Of course, in other embodiments, other linear drive structures can also be used, which are not limited here.

[0123] Optionally, the base 4110 is provided with a fourth slide rail extending longitudinally along the second direction Y, and the motion seat 4112 is provided with a fourth slider that slides in cooperation with the fourth slide rail. In this way, the movement of the fourth slider along the fourth slide rail guides the movement of the motion seat 4112 relative to the base 4110 in the second direction Y.

[0124] Optionally, the motion seat 4112 is provided with a fifth slide rail extending longitudinally along the third direction Z, and the transfer seat 412 is provided with a fifth slider that slides in cooperation with the fifth slide rail. In this way, the movement of the fifth slider along the fifth slide rail guides the movement of the transfer seat 412 relative to the motion seat 4112 in the third direction Z.

[0125] It should be noted that in some other embodiments, the motion seat 4112 may be movable relative to the base 4110 along the third direction Z, and the transfer seat 412 may be movable relative to the motion seat 4112 along the second direction Y. As long as it can drive the adhesive roller 451 to move along the second direction Y and the third direction Z, it is not limited here.

[0126] Specifically, in this embodiment, the adhesive applicator 40 further includes a pressing mechanism 47 disposed on the transfer seat 412. This pressing mechanism 47 has a pressing wheel 471 located downstream of the adhesive applicator 451. When the adhesive applicator 451 presses the double-sided adhesive layer a2 against the mandrel A on the transfer mechanism 13 reaching the adhesive applicator station B3, the pressing wheel 471 also abuts against the mandrel A on the transfer mechanism 13 reaching the adhesive applicator station B3. During the movement along the second direction Y with the transfer seat 412, the pressing wheel 471 smooths the double-sided adhesive layer a2 adhered to the mandrel A. Thus, as the adhesive applicator 451 rolls along the axial direction (i.e., the second direction Y) of the mandrel A, the double-sided adhesive layer a2 of the double-sided tape a3 is adhered to the mandrel A. At the same time, the pressure roller 471 also rolls along the axial direction of the mandrel A to further press the double-sided adhesive layer a2 pasted on the mandrel A (i.e., smooth it out), so that the double-sided adhesive layer a2 is more tightly adhered to the mandrel A.

[0127] Please see Figures 26 to 28 As shown, further, the peripheral surface of the pressure roller 471 is recessed inward to form a recessed surface 4710. This recessed surface 4710 is used to match the peripheral surface of the mandrel A, thereby increasing the pressing area between the pressure roller 471 and the mandrel A and improving the effect of pressing the double-sided adhesive layer a2 onto the mandrel A. Optionally, the outer surface of the mandrel A is an arc surface, so the recessed surface 4710 on the pressure roller 471 is also an arc surface, so that the recessed surface 4710 can match the outer surface of the mandrel A.

[0128] Specifically, in this embodiment, the pressing mechanism 47 includes a connecting seat 472, a support shaft 473, and a second elastic element 474. The connecting seat 472 is disposed on the transfer seat 412. The support shaft 473 is movably connected to the connecting seat 472, and the pressing wheel 471 is rotatably connected to the support shaft 473. The second elastic element 474 abuts against the support shaft 473 and the connecting seat 472 to provide a preload force that causes the support shaft 473 to have a tendency to move the pressing wheel 471 closer to the mandrel A. Optionally, the second elastic element 474 may be a spring.

[0129] Thus, as the transfer seat 412 drives the adhesive-applying roller 451 and the pressure roller 471 to move towards the mandrel A along the third direction Z, the pressure roller 471 first abuts against the mandrel A. As the transfer seat 412 continues to drive the adhesive-applying roller 451 towards the mandrel A, the second elastic element 474 is compressed and contracts until the adhesive-applying roller 451 presses the double-sided adhesive layer a2 of the double-sided tape a3 against the mandrel A (i.e., at this time, both the adhesive-applying roller 451 and the pressure roller 471 are pressing against the mandrel A). After both the adhesive-applying roller 451 and the pressure roller 471 are pressing against the mandrel A, the moving seat 4112 drives the adhesive-applying roller 451 and the pressure roller 471 to roll together along the axial direction of the mandrel A, so that the adhesive-applying roller 451 adheres the double-sided adhesive layer a2 of the double-sided tape a3 to the mandrel A, while the pressure roller 471 further presses the double-sided adhesive layer a2 adhered to the mandrel A. After the moving seat 4112 moves a preset distance along the second direction Y and stops moving, the cutting mechanism 46 cuts the double-sided adhesive layer a2 of the double-sided tape a3 from the upstream side of the adhesive-applying roller 451. Then, the moving seat 4112 drives the adhesive-applying roller 451 and the pressing roller 471 to continue rolling along the mandrel A for a distance, so that the tail end of the cut double-sided adhesive layer a2 is also pressed against the mandrel A by the adhesive-applying roller 451. Then, the transfer seat 412 drives the adhesive-applying roller 451 to move away from the mandrel A for a distance along the third direction Z, so that the adhesive-applying roller 451 separates from the mandrel A, and the pressing roller 471 remains in contact with the mandrel A under the elastic force provided by the second elastic element 474. Then, the moving seat 4112 drives the pressing roller 471 to roll along the axial direction of the mandrel A for a distance, so that the tail end of the cut double-sided adhesive layer a2 is also pressed against the mandrel A by the pressing roller 471. Finally, the motion seat 4112 and the transfer seat 412 return to their initial positions along the second direction Y and the third direction Z, respectively, to prepare for the next application of adhesive.

[0130] Optionally, the connecting seat 472 has a mounting groove 4721, and the support shaft 473 is disposed in the mounting groove 4721, so that the support shaft 473 can move a certain distance along the mounting groove 4721 (i.e., along the third direction Z). One end of the second elastic member 474 abuts against the connecting seat 472, and the other end abuts against the support shaft 473, so that when the pressure roller 471 is subjected to external pressure, it can overcome the elastic force of the second elastic member 474 and move relative to the connecting seat 472 along the third direction Z. Optionally, the second elastic member 474 can be a spring pin.

[0131] Please see Figures 23 to 25In some embodiments, the adhesive applicator 45 further includes a first limiting block 453, and the cutting mechanism 46 includes a cutter holder 462 and a cutter 463 and a second limiting block 464 disposed on the cutter holder 462. The cutter holder 462 is disposed on the transfer seat 412, so that the cutter holder 462 moves together with the transfer seat 412. The first limiting block 453 and the second limiting block 464 are disposed opposite to each other along the second direction Y, and a gluing channel h is formed between the first limiting block 453 and the second limiting block 464 for the double-sided adhesive tape a3 to pass through. The gluing channel h is located upstream of the adhesive applicator roller 451, that is, after the double-sided adhesive tape a3 unwound by the unwinding mechanism 43 passes through the gluing channel h and goes around the adhesive applicator roller 451, the adhesive applicator roller 451 attaches the double-sided adhesive layer a2 of the double-sided adhesive tape a3 to the mandrel A, and the release film a4 of the double-sided adhesive tape a3 is wound up on the winding mechanism 44.

[0132] The cutter holder 462 can move along the second direction Y toward the adhesive applicator 45 to the cutting position. When the cutter holder 462 moves to the cutting position, the second limiting block 464 abuts against the first limiting block 453, and the cutter 463 cuts the double-sided adhesive layer a2 between the first limiting block 453 and the adhesive applicator 451. In this way, the cutting depth of the cutter 463 is limited by the first limiting block 453 and the second limiting block 464, thereby ensuring that the cutter 463 only cuts the double-sided adhesive layer a2 of the double-sided tape a3 each time it cuts, without cutting the release film a4 of the double-sided tape a3.

[0133] In a specific embodiment, the cutting mechanism 46 further includes a cutting drive 461, which is mounted on the transfer seat 412, and a cutter holder 462 is mounted on the drive end of the cutting drive 461. The cutting drive 461 drives the cutter holder 462 to move toward the adhesive applicator 45, thereby causing the cutter 463 to cut the double-sided adhesive layer a2 of the double-sided tape a3 from the upstream side of the adhesive applicator roller 451. Optionally, the cutting drive 461 can be a cylinder.

[0134] In a specific embodiment, the adhesive applicator 45 includes an adhesive applicator base 452 disposed on the transfer seat 412. An adhesive applicator wheel 451 is rotatably connected to the adhesive applicator base 452. A first limiting block 453 is disposed on the adhesive applicator base 452 and its position relative to the adhesive applicator base 452 is adjustable along the second direction Y, so as to accommodate double-sided adhesive tape a3 and mandrel A of different specifications, thereby improving the compatibility of the equipment.

[0135] Furthermore, the first limiting block 453 is movably connected to the adhesive base 452 along the second direction Y. The first limiting block 453 has a first inclined surface 4531, which is inclined relative to a plane perpendicular to the second direction Y. The adhesive application mechanism 45 also includes an adjusting wedge 454 disposed on the adhesive base 452, which has a second inclined surface 4541 that is parallel to and fits against the first inclined surface 4531.

[0136] The adjusting wedge 454 is movable relative to the adhesive base 452 along a preset direction perpendicular to the second direction Y. Guided by the first inclined surface 4531 and the second inclined surface 4541, it pushes the first limiting block 453 to move along the second direction Y, thereby adjusting the position of the first limiting block 453 relative to the adhesive base 452 along the second direction Y. Thus, when the position of the first limiting block 453 needs adjustment, the adjusting wedge 454 is moved along the preset direction, thereby causing the first limiting block 453 to move relative to the adhesive base 452 along the second direction Y, thus achieving position adjustment of the first limiting block 453. Optionally, this preset direction is parallel to the first direction X.

[0137] Furthermore, the adhesive base 452 has a stop surface 4520, which is located on the side of the first limiting block 453 opposite to the second limiting block 464. An adjusting wedge 454 is located between the first limiting block 453 and the stop surface 4520. That is, the second limiting block 464, the first limiting block 453, the adjusting wedge 454, and the stop surface 4520 are arranged sequentially along the second direction Y. The first limiting block 453 and the adjusting wedge 454 abut against each other through the first inclined surface 4531 and the second inclined surface 4541, and the adjusting wedge 454 abuts against the stop surface 4520.

[0138] The abutment surface 4520 is parallel to the plane perpendicular to the second direction Y, so that during the process of the adjusting wedge 454 moving in the preset direction and pushing the first limiting block 453 to move in the second direction Y, the abutment surface 4520 limits the position of the adjusting wedge 454 in the second direction Y, so as to prevent the adjusting wedge 454 from being displaced in the second direction Y.

[0139] Furthermore, the adhesive applicator 45 also includes an adjusting screw 455, which is rotatably connected to the adhesive applicator 452 about its own axis. The axis of the adjusting screw 455 is parallel to the aforementioned preset direction, and one end of the adjusting screw 455 is threadedly connected to the adjusting wedge 454. Thus, by turning the adjusting screw 455, the adjusting wedge 454 can be moved along the preset direction, thereby pushing the first limiting block 453 to move along the second direction Y.

[0140] Furthermore, the first limiting block 453 has a third oblong hole 4532 extending longitudinally along the second direction Y. The adhesive applicator 45 also includes a threaded fastener (not shown), which passes through the third oblong hole 4532 and is threadedly connected to the adhesive applicator 452 to lock and fix the first limiting block 453 onto the adhesive applicator 452. Thus, when the position of the first limiting block 453 needs to be adjusted, the threaded fastener is first loosened so that the first limiting block 453 can move relative to the adhesive applicator 452 along the second direction Y. Then, the adjusting screw 455 is turned, thereby driving the adjusting wedge 454 to move relative to the adhesive applicator 452 in a preset direction, thereby driving the first limiting block 453 to move relative to the adhesive applicator 452 along the second direction Y. When the position of the first limiting block 453 is adjusted to the correct position, the adjusting screw 455 is stopped, and the threaded fastener is tightened to lock and fix the first limiting block 453 onto the adhesive applicator 452. Alternatively, threaded fasteners can be fastening screws.

[0141] Please see Figure 29 and Figure 30 In an embodiment of the present invention, the feeding device 50 includes a feeding drive mechanism 51 and a clamping mechanism 52. The feeding drive mechanism 51 is connected to the clamping mechanism 52, enabling the feeding drive mechanism 51 to drive the clamping mechanism 52 to move along a first direction X between the feeding station and the winding mechanism D. When the clamping mechanism 52 is located at the feeding station, it can clamp the mandrel A that has arrived at the feeding station from the transfer mechanism 13. When the clamping mechanism 52 is located at the winding mechanism D, it can place the clamped mandrel A on the winding mechanism D. Thus, when the transfer mechanism 13 arrives at the feeding station carrying the adjusted mandrel A, firstly, the feeding drive mechanism 51 drives the clamping mechanism 52 to move along the first direction X to the feeding station, and the clamping mechanism 52 clamps the mandrel A on the transfer mechanism 13 at the feeding station. Then, the loading drive mechanism 51 drives the clamping mechanism 52 to move along the first direction X to the winding mechanism D. At this time, the winding needle of the winding mechanism D extends and inserts into the mandrel A, so that the positioning part a1 of the mandrel A matches the winding needle. Then, the clamping mechanism 52 releases the mandrel A and returns to the loading station.

[0142] Specifically, in this embodiment, the loading drive mechanism 51 is also used to drive the clamping mechanism 52 to move along the third direction Z, so that the clamping mechanism 52 at the loading station can move closer to or further away from the mandrel A on the transfer mechanism 13 along the third direction Z, thereby achieving the clamping of the mandrel A on the transfer mechanism 13. Thus, when it is necessary to clamp the mandrel A that has arrived at the loading station on the transfer mechanism 13, the loading drive mechanism 51 drives the clamping mechanism 52 to move closer to the mandrel A on the transfer mechanism 13 along the third direction Z until the clamping mechanism 52 can clamp the mandrel A. Then, the clamping mechanism 52 clamps the mandrel A, and the clamping structure 136 of the transfer mechanism 13 releases the mandrel A. Then, the loading drive mechanism 51 drives the clamping mechanism 52 to move further away from the transfer mechanism 13 along the third direction Z and return, so that the clamping mechanism 52 causes the mandrel A to separate from the transfer mechanism 13, thus achieving the clamping of the mandrel A.

[0143] Specifically, in this embodiment, the feeding drive mechanism 51 is also used to drive the clamping mechanism 52 to rotate around a rotation axis, so as to align the mandrel A clamped on the clamping mechanism 52 with the winding needle of the winding mechanism D, thereby enabling the winding needle to be accurately inserted into the mandrel A. Thus, when the feeding drive mechanism 51 drives the clamping mechanism 52 to move along the first direction X to the winding mechanism D, firstly, the feeding drive mechanism 51 drives the clamping mechanism 52 to rotate around the rotation axis until the mandrel A on the clamping mechanism 52 is aligned with the winding needle of the winding mechanism D. At this time, the winding needle of the winding mechanism D extends and inserts into the mandrel A until the positioning part a1 of the mandrel A matches the winding needle. Then, the clamping mechanism 52 releases the mandrel A and returns to the feeding station under the drive of the feeding drive mechanism 51, so as to facilitate the next feeding action. Optionally, the rotation axis is parallel to the second direction Y.

[0144] Further, the feeding drive mechanism 51 includes a third support base 510, a fourth movable base 511, a fourth drive member 513, a fifth movable base 512, a fifth drive member 515, and a second rotary drive member 516. The third support base 510 is fixedly connected to the mounting plate 60. The fourth movable base 511 is movably connected to the third support base 510 along a first direction X. The fourth drive member 513 is mounted on the third support base 510 and connected to the fourth movable base 511, enabling the fourth drive member 513 to drive the fourth movable base 511 to move relative to the third support base 510 along the first direction X. The fifth movable base 512 is movably connected to the fourth movable base 511 along a third direction Z. The fifth drive member 515 is mounted on the fourth movable base 511 and connected to the fifth movable base 512, enabling the fifth drive member 515 to drive the fifth movable base 512 to move relative to the fourth movable base 511 along the third direction Z. The second rotary drive member 516 is mounted on the fifth movable seat 512, and the clamping mechanism 52 is mounted on the drive end of the second rotary drive member 516 so that it can be driven by the second rotary drive member 516 to rotate around the aforementioned rotation axis. Optionally, the fifth drive member 515 can be a cylinder. The second rotary drive member 516 can be a rotary cylinder.

[0145] Optionally, the feeding drive mechanism 51 further includes a third lead screw 514 and a third lead screw nut (not shown). The third lead screw 514 is rotatably connected to the third support base 510 about its own axis, and the axial direction of the third lead screw 514 is parallel to the first direction X. A fourth drive member 513 is connected to the third lead screw 514, enabling the fourth drive member 513 to drive the third lead screw 514 to rotate about its own axis. The third lead screw nut is threaded onto the third lead screw 514 and fixedly connected to the fourth moving base 511. Thus, when the fourth drive member 513 drives the third lead screw 514 to rotate, the third lead screw nut moves along the axial direction of the third lead screw 514 (i.e., the first direction X), thereby driving the fourth moving base 511 to move along the first direction X. Optionally, the fourth drive member 513 can be a motor.

[0146] Optionally, the third support 510 is provided with a sixth slide rail 5101 extending longitudinally along the first direction X, and the fourth movable seat 511 is provided with a sixth slider 5112 that slides in cooperation with the sixth slide rail 5101. In this way, the movement of the sixth slider 5112 along the sixth slide rail 5101 guides the movement of the fourth movable seat 511 relative to the third support 510 along the first direction X.

[0147] Optionally, the fourth movable seat 511 is provided with a seventh slide rail 5110 extending longitudinally along the third direction Z, and the fifth movable seat 512 is provided with a seventh slider 5120 that slides in cooperation with the seventh slide rail 5110. In this way, the movement of the seventh slider 5120 along the seventh slide rail 5110 guides the movement of the fifth movable seat 512 relative to the fourth movable seat 511 along the third direction Z.

[0148] Based on the aforementioned core rod feeding device, the present invention also provides a battery winding machine. This battery winding machine includes a winding mechanism D and the core rod feeding device as described in any of the above embodiments. The feeding device 50 of the core rod feeding device is used to transfer the core rod A arriving at the feeding station to the winding mechanism D. The winding needle of the winding mechanism D extends out, inserting into the center hole of the core rod A, and the positioning part a1 of the core rod A engages with the positioning needle, thereby enabling the winding needle to drive the core rod A to rotate. Thus, when a winding operation is required, the end of the winding strip is bonded and fixed to the core rod A by a double-sided adhesive layer a2, and the winding needle drives the core rod A to rotate, thereby winding the winding strip onto the core rod A to form a battery cell. Optionally, the winding strip can be a separator.

[0149] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0150] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
