Unless otherwise stated, the meaning of "multiple" is two or more.

[0036] At present, in the production of photovoltaic modules, the transportation of materials is mainly completed by manual operation, especially the materials such as welding strips and bus bars. In the actual production process, the welding strips and bus bars are generally wound on the spool, that is, the material transportation and feeding are realized by operating the spool. Since the spool is difficult to fix, it is generally manually transported to the feeding position. After feeding, the material head on the spool needs to be fixed to the mechanical arm, and the material head is pulled to the preset position by the mechanical arm to prepare for subsequent automatic welding. Since the welding strip and the bus bar are soft, it is difficult to grasp the material head by the mechanical arm, so manual feeding operation is still required.

[0037] To solve one or more of the above technical problems, to improve the level of automation of photovoltaic module production. To this end, one embodiment of the present application provides a spool automatic feeding system, comprising: a conveying device comprising a trolley and a fixing tool, the trolley having a carrying platform, the fixing tool being arranged on the carrying platform, the fixing tool being used to fix a spool, and the trolley being used to transport the spool; a material fixing device comprising a material table, a fixing crossbar and an axial fixing assembly, the fixing crossbar having opposite first and second ends, the first end of the fixing crossbar being fixed to the material table, and the second end of the fixing crossbar being suspended; the spool having an axial through hole, the fixing crossbar being used to pass through the axial through hole to receive the spool, and the axial fixing assembly being used to be fixed at the second end to limit the axial movement of the spool on the fixing crossbar; and an automatic feeding device; when the trolley transports the spool to a predetermined position, the automatic feeding device picks up the spool on the trolley and sleeves the spool on the outer periphery of the fixing crossbar, and the automatic feeding device is also used to sleeve the axial fixing assembly on the second end to fix the spool on the fixing crossbar.

[0038] The spool automatic feeding system provided by the embodiment of the present application comprises a conveying device, an automatic feeding device and a material fixing device, the conveying device comprises a trolley and a fixing tool, when material needs to be transported, a spool is placed on the trolley by manual, the fixing tool fixes the spool on the trolley, the trolley automatically transports the spool to a predetermined position to realize automatic material transportation. At this time, the automatic feeding device picks up the spool on the trolley and sets it on the fixing crossbar of the material fixing device, and then sets the axial fixing assembly at one end of the fixing crossbar to fix the spool on the fixing crossbar, realizes automatic feeding, reduces labor cost and loss, and improves the level of automation of photovoltaic module production.

[0039] The implementation details of the spool automatic feeding system of the embodiment will be specifically described below, and the following content is only provided for the implementation details for easy understanding, and is not necessary for implementing the present solution.

[0040] Please refer to Figure 1The reel automatic feeding system provided by the embodiment comprises: a conveying device 100 comprising a carrying trolley 110 and a fixing tool 120, the carrying trolley 110 has a bearing platform 111, the fixing tool 120 is arranged on the bearing platform 111, the fixing tool 120 is used for fixing a reel 400, and the carrying trolley 110 is used for conveying the reel 400; a material fixing device 200 comprising a material table 210, a fixing crossbar 220 and an axial fixing assembly 230, the fixing crossbar 220 has opposite first and second ends, the first end of the fixing crossbar 220 is fixed to the material table 210, and the second end of the fixing crossbar 220 is suspended; the reel 400 has an axial through hole 410, the fixing crossbar 220 is used for being arranged through the axial through hole 410 to receive the reel 400, and the axial fixing assembly 230 is used for being fixed at the second end to limit the axial movement of the reel 400 on the fixing crossbar 220; and an automatic feeding device 300; when the carrying trolley 110 conveys the reel 400 to a preset position, the automatic feeding device 300 picks up the reel 400 on the carrying trolley 110 and arranges the reel 400 on the outer periphery of the fixing crossbar 220, and the automatic feeding device 300 is also used for arranging the axial fixing assembly 230 on the second end to fix the reel 400 on the fixing crossbar 220.

[0041] Therefore, when the carrying trolley 110 conveys the reel 400 on which the welding strip or the bus bar is wound, the reel 400 can be fixed by the fixing tool 120, which can avoid the reel 400 from falling off the carrying trolley 110 due to vibration or the like, and the reel 400 can be fixed at a specific position or region on the bearing platform 111 by the fixing tool 120, so that the automatic feeding device 300 can accurately pick up the reel 400 when the carrying trolley 110 reaches the preset position. After picking up the reel 400, the automatic feeding device 300 arranges the reel 400 on the fixing crossbar 220, then picks up the axial fixing assembly 230 and arranges the axial fixing assembly 230 on the second end of the fixing crossbar 220, and finally fixes the reel 400 on the fixing crossbar 220 by the axial fixing assembly 230, thereby realizing automatic feeding.

[0042] Optionally, the carrying trolley 110 can be driven by a motor to drive a roller to travel along a preset track to receive the material (i.e., the bobbin 400) at a position where the material is received, and then transport the material to the preset position along the preset track; or, the traveling track can be set according to actual needs, and the carrying trolley 110 is arranged on the traveling track, and the carrying trolley 110 reciprocates on the traveling track to transport the bobbin 400.

[0043] Please also refer to Figure 2 In some embodiments, the fixing tool 120 comprises a fixing mechanism 121 and a clamping mechanism 122; the fixing mechanism 121 is two and oppositely arranged on the bearing platform 111, and the two fixing mechanisms 121 are used to clamp and fix the bobbin 400 on opposite sides of the bobbin 400; the clamping mechanism 122 is arranged at the edge of the bearing platform 111, and the clamping mechanism 122 is used to clamp the end of the material wound on the bobbin 400.

[0044] Specifically, by arranging two fixing mechanisms 121 on opposite sides of the bearing platform 111, the two fixing mechanisms 121 can fix the bobbin 400 on opposite ends of the bobbin 400, thereby improving the fixing effect of the bobbin 400. In addition, by clamping the end of the material, i.e., the material head of the welding strip or the bus bar, by the clamping mechanism 122, the automatic feeding device 300 can accurately clamp the material head of the welding strip or the bus bar after the bobbin 400 is fixed, and then pull the welding strip or the bus bar to the processing (such as welding) position for processing. That is, the fixing tool 120 not only fixes the bobbin 400, but also clamps the end (i.e., the material head) of the material.

[0045] In some embodiments, the structures of the two fixing mechanisms 121 can be the same or different. When the structures of the two fixing mechanisms 121 are the same, one fixing mechanism 121 is taken as an example for description. Please also refer to Figure 3The fixing mechanism 121 comprises a handle 121a, a first spring 121b and a shaft fixing structure 121c; the first spring 121b is parallel to the bearing platform 111 in the axial direction, one end of the first spring 121b is fixedly connected to the bearing platform 111, the other end of the first spring 121b is drivingly connected to the handle 121a and fixedly connected to the shaft fixing structure 121c; the first springs 121b of the two fixing mechanisms 121 are coaxially arranged, and the shaft fixing structures 121c of the two fixing mechanisms 121 are oppositely arranged, the two fixing mechanisms 121 are configured to: turning the two handles 121a drives the two first springs 121b to compress to make the two shaft fixing structures 121c move away from each other one by one, when the spool 400 is placed on the bearing platform 111, the two first springs 121b are released, and the two first springs 121b drive the two shaft fixing structures 121c to move close to each other to hold the spool 400.

[0046] Specifically, when it is needed to place the spool 400 on the bearing platform 111, the handle 121a can be rotated to make the opposite ends of the two first springs 121b move away from each other, so as to compress the two first springs 121b. At this time, the two first springs 121b drive the two shaft fixing structures 121c to move away from each other, so that the space between the two shaft fixing structures 121c is increased, the operator can place the spool 400 on the bearing platform 111, and the spool is located between the two shaft fixing structures 121c. Then, the handle 121a is released, the force applied to the two first springs 121b by the handle 121a is removed, and the two first springs 121b restore to the original state under the action of their own elastic force, driving the two shaft fixing structures 121c to move close to each other, and the two shaft fixing structures 121c are respectively inserted into the spool 400 from opposite sides of the spool 400 and fix the spool 400.

[0047] More specifically, the bearing platform 111 can be provided with a fixed seat 112, and a through hole (not shown in the figure) coaxial with the first spring 121b is arranged on the fixed seat 112, and a connecting rod 121d is arranged to pass through the through hole, one end of the connecting rod 121d is drivingly connected to the handle 121a, and the other end is fixedly connected to the shaft fixing structure 121c, the first spring 121b is sleeved on the outer periphery of the connecting rod 121d, one end of the first spring 121b abuts against the shaft fixing structure 121c, and the other end of the first spring 121b abuts against the fixed seat 112. When it is necessary to fix the spool 400, the handle 121a can be rotated to drive the shaft fixing structure 121c to move away from each other and compress the corresponding first spring 121b, and after the spool 400 is placed, the handle 121a is released, and the first spring 121b restores to its original state under the action of its own elastic force, driving the shaft fixing structure 121c to move, specifically, the two shaft fixing structures 121c move close to each other to fix the spool 400.

[0048] Optionally, the handle 121a can drive the connecting rod to move by winding a rope or a transmission chain, or by a gear transmission, and the specific arrangement can be selected and arranged by those skilled in the art according to actual needs under the guidance of the present application, which is not specifically described and limited here.

[0049] Further, when the shaft fixing structure 121c is moved away from each other by rotating the handle 121a to compress the first spring 121b, in order to prevent the first spring 121b from automatically resetting before the spool 400 is placed, a locking pin (not shown in the figure) can be arranged to fix the handle 121a, so that the shaft fixing structure 121c keeps compressing the first spring 121b.

[0050] It can be understood that the spool 400 is generally composed of a winding drum and baffles arranged at opposite ends of the winding drum, and a plurality of fixing holes (not shown in the figure) can be arranged on the two baffles of the spool 400, and the shaft fixing structure 121c is fixed to the spool 400 by inserting the fixing holes. Since the two shaft fixing structures 121c are respectively arranged on the opposite sides of the spool 400 to fix the spool 400, a plurality of fixing holes can be arranged at intervals along the circumference of the baffles, and at this time, the thickness of the baffles can be appropriately increased to avoid the situation that the side wall of the fixing hole surrounded by the baffles is insufficient in mechanical strength due to the small thickness after the fixing hole is arranged.

[0051] In other possible embodiments, the fixing base 112 is provided with a threaded hole, a threaded rod is threadedly connected to the fixing base 112 and passes through the threaded hole, one end of the threaded rod is fixedly connected to the handle 121a, the other end of the threaded rod is fixedly connected to the shaft fixing structure 121c, and the first spring 121b can be sleeved on the outer periphery of the threaded rod and abut against the fixing base 112 and the shaft fixing structure 121c at both ends. In this way, when the handle is rotated, the threaded rod can be moved in the axial direction, thereby driving the shaft fixing structure 121c to move, making the two shaft fixing structures 121c move away from each other, and the two first springs 121b are compressed. After the bobbin 400 is placed, the handle 121a is rotated again, so that the two shaft fixing structures 121c move close to each other, thereby fixing the bobbin 400. At the same time, the first spring 121b applies a pushing force to the shaft fixing structure 121c, which can eliminate the gap between the threads of the threaded rod and the threads of the threaded hole, and ensure a stable fixing effect.

[0052] Please refer again to Figure 3 In some embodiments, the shaft fixing structure 121c includes a cross arm 121e and two fixing components 121f. The cross arm 121e is fixedly connected to the first spring 121b, and the axial direction of the cross arm 121e is parallel to the bearing platform 111 and perpendicular to the axial direction of the first spring 121b. The two fixing components 121f are respectively arranged at both ends of the cross arm 121e and located on the side of the cross arm 121e away from the first spring 121b, and are used for clamping the baffle to fix the bobbin.

[0053] Specifically, the first spring 121b is located between the cross arm 121e and the fixing base 112, and the cross arm 121e and the first spring 121b interact with each other when the shaft fixing structure 121c moves. By arranging one fixing component 121f at each end of the cross arm 121e, the force application points for the bobbin 400 can be increased, and the fixing effect of the bobbin 400 can be improved. The two shaft fixing structures 121c include four fixing components 121f, and the bobbin 400 is fixed from four points. In other possible embodiments, the number of fixing components 121f on each cross arm 121e can be the same or different, and can be one or more. For example, one fixing component 121f is arranged on one cross arm 121e, and two fixing components 121f are arranged on one cross arm 121e, thereby forming three force application points on the baffle of the bobbin 400.

[0054] Please refer to Figure 4 and Figure 5In some embodiments, the fixing assembly 121f comprises a mounting arm 121g, a first inclined top 121h, a second inclined top 121i, and a second spring 121j. The mounting arm 121g is fixed to the cross arm 121e and extends away from the first spring 121b. The first inclined top 121h is fixed to one end of the mounting arm 121g away from the cross arm 121e and is located on the upper side of the mounting arm 121g. The height of the first inclined top 121h decreases along the extension direction of the mounting arm 121g. The second inclined top 121i has opposite connecting ends and a free end. One end of the second spring 121j is fixedly connected to the mounting arm 121g, and the other end is fixedly connected to the free end.

[0055] Specifically, the mounting arm 121g, the first inclined top 121h, and the second inclined top 121i together form an arrow-shaped structure, which facilitates the smooth entry of the fixing assembly 121f into the fixing hole of the baffle. When the fixing assembly 121f is inserted into the fixing hole, the second spring 121j is compressed by the inner wall of the fixing hole, so that the spool 400 is locked by the fixing assembly 121f. When the carrying trolley 110 transports the spool 400 to the preset position, the automatic feeding device 300 picks up the spool 400 and lifts it upwards. At this time, the compressed second spring 121j pushes the second inclined top 121i to rotate under the action of its own elastic force. The second inclined top 121i continuously pushes the spool 400 and compresses the first spring 121b, thereby pushing the spool 400 to separate from the fixing assembly 121e.

[0056] In some cases, when the spool 400 is placed on the bearing platform, the baffle contacts the first inclined top 121h. Due to the inclined arrangement of the first inclined top 121h, the baffle can gradually push away the first inclined top 121h, so that the oppositely arranged shaft fixing structures 121c move away from each other and compress the first spring 121b. When the fixing assembly 121f passes the edge of the baffle surrounding the fixing hole, the fixing assembly 121f extends into the fixing hole and clamps the spool 400 under the action of the first spring 121b.

[0057] Please refer to Figure 6 In some embodiments, the clamping mechanism 122 comprises two clamping assemblies 123. The two clamping assemblies 123 are located at the same horizontal height and are arranged at intervals. The two clamping assemblies 123 are used to clamp the end of the material wound on the spool 400.

[0058] Specifically, after the operator fixes the bobbin 400, the two spaced-apart clamping assemblies 123 fix the material head, that is, there is a straightened part between the two spaced-apart clamping assemblies 123, facilitating the automatic feeding device 300 to pick up the material head and pull the material head to a specific position for subsequent automatic processing. It can be understood that the "specific position" is determined by the actual production equipment and process, such as the position of automatic welding of the equipment, or the position of clamping the material head of the equipment, and the person skilled in the art can determine it according to the actual situation, which is not specifically described here.

[0059] Please refer to Figure 7 In some embodiments, the clamping assembly 123 includes two oppositely arranged elastic sheets 123a, and the two elastic sheets 123a are used to clamp the end portion. Especially when the elastic sheet 123a is made of metal, the clamping of the material head can be realized by the elasticity of the metal sheet itself.

[0060] Further, a third spring 123b can be arranged between the two elastic sheets 123a, one end of the third spring 123b is connected to one of the elastic sheets 123a, and the other end is connected to the other elastic sheet 123a, and the third spring 123b is used to pull the two elastic sheets 123a.

[0061] Specifically, the two elastic sheets 123a are arranged in parallel, and the opposite ends of the two elastic sheets 123a are respectively connected to one end of the third spring 121b. The operator can place the material head between the two elastic sheets 123a, and the two elastic sheets 123a are stretched apart, thereby stretching the third spring 123b, and the third spring 123b drives the two elastic sheets 123a to clamp the material head under the action of the elastic force.

[0062] Optionally, the elastic sheet 123a can be made of metal, or made of plastic or the like. Preferably, a flexible material such as resin, rubber, and silicone can be arranged on the opposite surfaces of the two elastic sheets 123a to avoid deformation of the material head when clamped.

[0063] Please refer to Figure 6 Further, a support rod 124 can be arranged on the bearing platform 111, and the two clamping assemblies 123 are arranged on the support rod 124 to lift the material head at a certain angle, facilitating the automatic feeding device 300 to pick up the material head.

[0064] Please refer to Figure 8In some embodiments, the axial fixing assembly 230 comprises a main body 231 and a locking structure 232, the main body 231 is provided with a first through hole 231a for accommodating the fixing crossbar 220, and the locking structure 232 is fixed to the main body 231 and used for locking the fixing crossbar 220 and limiting the bobbin 400 to prevent the bobbin 400 from moving axially relative to the fixing crossbar 220.

[0065] Specifically, after the automatic feeding device 300 sets the bobbin 400 on the fixing crossbar 220, the automatic feeding device 300 picks up the axial fixing assembly 230 and sets the axial fixing assembly 230 on the second end of the fixing crossbar 220, so that the axial fixing assembly 230 blocks the bobbin 400 from moving axially along the fixing crossbar 220, thereby preventing the bobbin 400 from being separated from the fixing crossbar 220 and ensuring that the equipment can normally complete the production work.

[0066] In some embodiments, the main body 231 is in the shape of a circular truncated cone, the sidewall of the main body 231 is provided with a groove 231b, the bottom of the groove 231b is provided with a second through hole 231c communicating with the first through hole 231a, and the locking structure 232 is located in the groove 231b and at least partially extends into the first through hole 231a via the second through hole 231c.

[0067] It should be noted that the diameter of at least one of the two bottom surfaces of the main body 231 is greater than the diameter of the axial through hole 410 of the bobbin 400, so that the main body 231 can hold the bobbin 400 and prevent the bobbin 400 from being separated from the fixing crossbar 220. Preferably, the diameter of one bottom surface of the main body 231 is greater than the diameter of the axial through hole 410, and the diameter of the other bottom surface is less than the diameter of the axial through hole 410. When the axial fixing assembly 230 is installed, the bottom surface with the smaller diameter of the main body 231 faces the bobbin 400 and extends into the axial through hole 410, and the bottom surface with the larger diameter of the main body 231 faces away from the bobbin 400. At this time, the sidewall of the main body 231 abuts against the inner wall of the axial through hole 410 to fix the bobbin 400. It can be understood that the bottom surface with the larger diameter of the main body 231 can also be arranged to face the bobbin 400, and at this time, the bottom surface is in contact with the surface of the baffle.

[0068] In some embodiments, the locking structure 232 is a plurality of locking structures 232, which are arranged at intervals around the axis of the first through hole 231a. That is, the side wall of the main body 231 is provided with a plurality of grooves 231b around the first through hole 231a, and each of the grooves 231b is provided with the locking structure 232, and each of the locking structures 232 extends into the first through hole 231a to fix the fixed crossbar 220.

[0069] Optionally, the locking structure 232 can be two, three or more, and preferably is uniformly arranged on the main body 231. In addition, in other embodiments, the main body 231 can also not be a circular truncated cone, such as a hemisphere, a semi-ellipsoid or other similar shapes, as long as it can be fixed on the second end of the fixed crossbar 220 to prevent the spool 400 from being separated from the fixed crossbar 220.

[0070] Please refer to Figure 9 In some embodiments, the locking structure 232 includes a mounting rod 232a, a clamping portion 232b and a fourth spring 232c, the middle part of the mounting rod 232a is rotatably connected to the main body 231, the clamping portion 232b is fixed to one end of the mounting rod 232a and at least partially extends into the first through hole 231a, the other end of the mounting rod 232a is fixedly connected to one end of the fourth spring 232c, and the other end of the fourth spring 232c is fixedly connected to the bottom of the groove 231b; the fourth spring 232c is configured to compress the fourth spring 232c to drive the clamping portion 232b away from the first through hole 231a to release the fixed crossbar 220, and release the fourth spring 232c to drive the clamping portion 232b to extend into the first through hole 231a to clamp the fixed crossbar 220.

[0071] Specifically, the middle part of the mounting rod 232a can be rotatably connected to the main body 231 by means of a pivot connection, i.e., the two side walls opposite to the groove 231b are rotatably connected to form a lever. The clamping part 232b is fixed to one end of the mounting rod 232a. One end of the fourth spring 232c is fixed to one side of the mounting rod 232a towards the bottom of the groove 231b. The other end of the fourth spring 232c is fixed to the bottom of the groove 231b. In the natural state or when the axial fixing assembly 230 is arranged on the fixed cross rod 220, the fourth spring 232c lifts one end of the mounting rod 232a, so that the clamping part 232b extends into the first through hole 231a, thereby enabling the clamping part 232b to clamp the fixed cross rod 220. When it is necessary to remove the axial fixing assembly 230, one end of the mounting rod 232a is pressed to compress the fourth spring 232c, at which time the clamping part 232b is lifted to disengage the fixed cross rod 220, thereby enabling the axial fixing assembly 230 to disengage the fixed cross rod 220.

[0072] It can be understood that the fixed cross rod 220 is provided with a threaded segment, and the clamping part 232b is an inclined barb towards the fourth spring 232c, which extends into the first through hole 231a to clamp the thread of the threaded segment.

[0073] In this way, when the axial fixing assembly 230 is arranged on the fixed cross rod 220, the barb can be lifted to avoid the thread (similar to inclined surface cooperation) under the blockage of the thread, thereby enabling the axial fixing assembly 230 to be smoothly arranged on the fixed cross rod 220. Conversely, the end of the barb is embedded in the gap between adjacent threads. Due to the inclined arrangement of the barb, the barb can hook the thread to prevent the axial fixing assembly 230 from disengaging the fixed cross rod 220. As long as one end of the fourth spring 232c connected to the mounting rod 232a is pressed, the barb can disengage the thread.

[0074] In other possible embodiments, the threaded segment can also be provided as a step with a certain pitch. Specifically, a plurality of different steps can be arranged according to the model of the spool 400, and the barb can hook different steps to fix different models of the spool 400.

[0075] In some embodiments, the automatic feeding device 300 can be a mechanical arm which can pick up the spool 400, the end of the material and the axial fixing assembly 230 by clamping or the like.

[0076] Optionally, the automatic feeding device 300 can be a mechanical arm with multiple joints, so that it can pick up target objects from different heights, distances and angles, has high degrees of freedom and can adapt to the setting requirements of different production lines. The mechanical arm can include a gripper for picking up the bobbin 400 and the axial fixing assembly 230, and the gripper can be arranged to be telescopic and rotatable relative to the last joint of the mechanical arm, so as to improve the degrees of freedom of the gripper when picking up and placing objects.

[0077] In order to improve the stability of the gripper in picking up the bobbin 400 and the axial fixing assembly 230, a strip-shaped, conical and / or semispherical protrusion or the like can be arranged on the clamping part of the gripper for clamping objects, so as to increase the friction between the clamping part and the picked-up objects and prevent the picked-up objects from falling off.

[0078] Further, in order to avoid damage to the bobbin 400 or the axial fixing assembly 230 when the gripper clamps them, and in particular because the gripper needs to pick up the material head after feeding and pull the material head to a specific position, in order to prevent the material head from sliding, a rubber, silicone or other elastic object can be arranged on the clamping part. When the clamping part clamps the bobbin 400 or the axial fixing assembly 230, the elastic object can prevent the bobbin 400 or the axial fixing assembly 230 from being damaged, and can also ensure that the gripper can stably clamp the material head.

[0079] The operation mode of the bobbin automatic feeding system provided by the embodiment is as follows:

[0080] Firstly, the operator unpacks the bobbin with material, then finds the material head, clamps and fixes the material head by two clamping assemblies 123, tightens the material, rotates the handle 121a to make the oppositely arranged shaft fixing structures 121c move away from each other and compress the corresponding first springs 121b, then places the bobbin 400 on the bearing platform 111, releases the handle 121a, and the first spring 121b drives the corresponding shaft fixing structure 121c to clampingly fix the bobbin 400. Then, the carrying trolley 110 transports the bobbin 400 to the preset position according to the preset route, the mechanical arm removes the axial fixing assembly 230 on the fixed cross rod 220 and places it on the material table 210, if there is a bobbin 400 with used-up material on the fixed cross rod 220, the bobbin 400 is removed and placed on the material table 210. Then, the mechanical arm moves to the carrying trolley 110 to pick up the bobbin 400, and sets the bobbin 400 on the fixed cross rod 220, then picks up the axial fixing assembly 230 on the material table 210 and sets it on the fixed cross rod 220 to fix the bobbin 400. Then, the mechanical arm picks up the material head clamped and fixed by two clamping assemblies 123, and drags the material head to a specific position for processing. Finally, the mechanical arm picks up the empty bobbin on the material table 210 and places it on the bearing platform 111 of the carrying trolley 110, and the carrying trolley 110 transports the empty bobbin away.

[0081] It can be understood that a specific area can be planned on the material table 210 for placing the axial fixing assembly 230, and another specific area can be planned for placing the empty bobbin. In this way, the mechanical arm can accurately pick up the target object.

[0082] In order to further improve the picking accuracy, a camera or other sensor can be arranged on the mechanical arm, such as using machine vision technology to identify and pick up.

[0083] In addition, please refer again to Figure 6 In order to prevent the empty bobbin from falling off the carrying trolley 110 due to rolling or other reasons, a blocking rod 125 can be arranged at the edge of the bearing platform 111 where the fixing mechanism 121 is not arranged, to block the empty bobbin and prevent it from falling off the carrying trolley 110. It should be noted that the length of the blocking rod 125 in the direction parallel to the bearing platform 111 should be greater than the size of the bobbin, so as to ensure that the blocking rod 125 can block the empty bobbin.

[0085] The third embodiment of the present application provides a spool automatic feeding system, comprising the axial fixing assembly of the first embodiment.

The above description of the embodiments is only used to help understand the idea of the present application, and there will be changes in the specific embodiments and application scope.
