Obviously, the embodiments described below are only some of the embodiments of the present application, rather than all the embodiments.

[0057] In the description of the present application, it should be understood that when one component is considered to be "connected" to another component, it can be directly connected to the other component or there can be a component arranged in the middle. When one component is considered to be "arranged on" another component, it can be directly arranged on the other component or there can be a component arranged in the middle.

[0058] In addition, the terms "long", "short", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application, and do not indicate or imply that the device or element referred to must have this particular orientation, be constructed in this particular orientation, or operate in this particular orientation. It cannot be understood as a limitation of the present application.

[0059] The technical solutions of the present application will be further described below with reference to the specific embodiments. Figures 1-6 The technical solutions of the present application will be further described below with reference to the specific embodiments.

[0060] Please refer to Figure 1 The embodiment of the present application provides a laser cutting equipment based on steering wheel processing, which comprises a rack 1, a supporting mechanism 2, an inner cutting mechanism 3 and an outer cutting mechanism 4.

[0061] The rack 1 is used for providing mounting positions for each mechanism, and the specific structure of the rack 1 can be adjusted according to actual needs, which is not specifically limited here. In this embodiment, the rack 1 is a three-dimensional frame structure, and the rack 1 has a platform.

[0062] The supporting mechanism 2 is arranged on the rack 1, and is used for placing the steering wheel. When the steering wheel is placed on the supporting mechanism 2, the supporting mechanism 2 is used for locking the steering wheel and horizontally arranging the steering wheel, which is beneficial to accurately cutting the scrap edges at the inner edge and the outer edge of the steering wheel. It can be understood that the outer edge of the steering wheel can be understood as the outer peripheral surface, and the inner edge of the steering wheel can be understood as the side edge arranged inside the steering wheel and having a hollow profile. The inner edge and the outer edge of the steering wheel are prone to form outwardly protruding scrap edges during the forming process, and the scrap edges need to be cut for subsequent leather processing of the steering wheel.

[0063] On this basis, the inner cutting mechanism 3 is arranged on the rack 1 and above the steering wheel, and is used for laser cutting the inner edge of the steering wheel. At the same time, the outer cutting mechanism 4 is also arranged on the rack 1, and is arranged adjacent to the supporting mechanism 2 and below the steering wheel, and is used for laser cutting the outer edge of the steering wheel.

[0064] The laser cutting equipment based on steering wheel processing provided by the embodiment is provided with the supporting mechanism 2 on the rack 1, and the supporting mechanism 2 can position the steering wheel. On this basis, the inner cutting mechanism 3 can laser cut the scrap edges of the inner edge of the steering wheel above the steering wheel, and the outer cutting mechanism 4 can laser cut the scrap edges of the outer edge of the steering wheel below the steering wheel. The inner cutting mechanism 3 and the outer cutting mechanism 4 can operate simultaneously and do not interfere with each other, so as to simultaneously cut and process the inner edge and the outer edge of the steering wheel. Since laser beams are used to realize the cutting action, the laser beams have the advantages of high cutting precision and good cutting consistency, and the processing efficiency and the processing precision are significantly improved.

[0065] Refer to Figure 1 and Figure 2 To realize the locking and positioning of the steering wheel. The supporting mechanism 2 provided by the embodiment comprises a base 21, a positioning column 22 and a locking assembly 23.

[0066] The base 21 is fixedly arranged on the rack 1. Specifically, the base 21 has a flat structure, is arranged horizontally, and is fixedly connected with the platform of the rack 1, so that the base 21 is fixedly installed on the rack 1.

[0067] In addition, the positioning column 22 is arranged on the top of the base 21 and is used for plug-in connection with the hole position on the inner side of the steering wheel. It should be explained that the inner side of the steering wheel has a hole position, which is defined as an inner hole herein, and the hole position on the inner side of the steering wheel is used for connection with the steering link of the automobile and plays a role of assembly. In this embodiment, the steering wheel is positioned by using the hole position in the steering wheel, so that the positioning difficulty of the steering wheel can be simplified and a positioning jig does not need to be additionally installed.

[0068] Specifically, in some embodiments, the positioning column 22 is vertically arranged, the bottom of the positioning column 22 is fixedly connected with the top of the base 21, at this time, the base 21 provides stable support for positioning, and at the same time, the outer shape contour of the top end of the positioning column 22 is matched with the hole position on the inner side of the steering wheel, at this time, the steering wheel can be placed on the top of the positioning column 22 and the positioning column 22 can be inserted into the hole position in the steering wheel, so that the steering wheel is preliminarily positioned and can be horizontally placed on the positioning column 22.

[0069] On this basis, the locking assembly 23 is arranged on the positioning column 22, and the locking assembly 23 is used for movable locking of the steering wheel. The positioning column 22 is hollow, the hollow interior of the base 21 is defined as a containing cavity 211, and the locking assembly 23 is located in the containing cavity 211 of the positioning column 22. In some embodiments, the locking assembly 23 includes a driving cylinder 231, a driving block 232, and a locking block 233.

[0070] The driving cylinder 231 is arranged in the positioning column 22 and located in the containing cavity 211. Specifically, the driving cylinder 231 is fixedly arranged in the positioning column 22, and the telescopic rod of the driving cylinder 231 is vertically arranged upward. At the same time, the driving block 232 is arranged on the telescopic rod of the driving cylinder 231. Specifically, the bottom of the driving block 232 is fixedly connected with the end of the telescopic rod, the driving cylinder 231 is used for driving the driving block 232 to move up and down, and the outer side of the driving block 232 has an inclined guide groove. In this embodiment, the driving block 232 has a quadrangular frustum structure, the side surface of the driving block 232 is an inclined side surface, the inclined guide groove is recessed from the outside to the inside and arranged on the inclined side surface of the driving block 232, and the inclined guide groove extends from the bottom to the top of the driving block 232. The opening contour of the inclined guide groove is in a T shape or a dovetail shape, which is not specifically limited herein, and the T shape is used as an example in this embodiment.

[0071] On this basis, the locking block 233 is horizontally movably arranged on the positioning column 22, and the locking block 233 is slidably matched with the inclined guide groove, and the driving block 232 is used to drive the locking block 233 to horizontally extend and retract, so that the driving block 232 is movably abutted with the inner wall of the hole position of the steering wheel.

[0072] Specifically, the locking block 233 in the embodiment is in a long strip structure, the positioning column 22 is also hollow arranged, and the inside of the positioning column 22 is communicated with the accommodating cavity 211 of the positioning column 22; a sliding hole is horizontally arranged on the positioning column 22, and the positioning column 22 is horizontally slidably arranged at the sliding hole. Under the guidance of the sliding hole, the locking block 233 can reciprocate in the horizontal direction. At this time, one end of the locking block 233 is located outside the positioning column 22, and the other end is located inside the positioning column 22. The end of the locking block 233 inside the positioning column 22 has a sliding part, and the outer shape of the sliding part is consistent with the opening profile of the inclined guide groove. In the embodiment, the sliding part is a T-shaped block structure, and the sliding part is slidably arranged in the inclined guide groove.

[0073] Based on the above arrangement, when the driving cylinder 231 drives the driving block 232 to descend, under the cooperation of the inclined guide groove and the sliding part, the locking block 233 can be retracted towards the inside of the positioning column 22, and the steering wheel can be placed on the top of the positioning column 22. When the steering wheel is placed on the positioning column 22, the driving cylinder 231 is started, and the driving cylinder 231 drives the driving block 232 to ascend. At this time, under the cooperation of the inclined guide groove and the sliding block, the locking block 233 can be pushed out towards the outside of the positioning column 22, and then the end of the locking block 233 located outside can be abutted to the inner wall of the hole position of the steering wheel, so as to increase the friction between the positioning column 22 and the steering wheel, thereby realizing the locking of the steering wheel, which is fast and efficient.

[0074] In addition, the inner wall of the hole position of part of the steering wheel also has a convex or concave structure. At this time, the locking block 233 protruding to the outside of the positioning column 22 can also be clamped and matched with the convex or concave structure, so as to improve the locking stability of the steering wheel.

[0075] Reference Figure 3 In an embodiment provided in the present application, the inner cutting mechanism 3 comprises a displacement assembly 31 and a first laser emitter 32. The displacement assembly 31 is arranged on the rack 1, and the first laser emitter 32 is arranged on the displacement assembly 31. The displacement assembly 31 is used to drive the first laser emitter 32 to displace in a three-dimensional space, and the first laser emitter 32 is used to emit a vertically downward laser beam.

[0076] Based on the above setting, the displacement assembly 31 can adjust the position of the first laser emitter 32, so that the laser beam emitted by the first laser emitter 32 can move along a specific contour or trajectory, thereby realizing precise cutting action. It can be understood that the first laser emitter 32 mainly includes a laser, a beam expander, an ultraviolet mirror, and a cutting head. The laser emits a straight beam which is converted into a collimated beam through the center of the beam expander. The collimated beam is reflected by the center of the ultraviolet mirror and enters the cutting head, so that the laser beam can be focused on the appropriate cutting position to achieve precise cutting effect. Here, the principle of the first laser emitter 32 is not described in detail. As long as a component that can emit a laser beam is used, it should be included in the interpretation range of the present application.

[0077] In addition, the above-mentioned specific contour or trajectory can be understood as a cutting path obtained by analyzing computer technology, which has a starting point and an ending point. The path between the starting point and the ending point is a specific path, and the specific contour of the path is determined by the contour of the steering wheel itself. Therefore, it is not unique. Regardless of the shape of the path, it should be included in the interpretation range of the present application.

[0078] Further, with reference to Figure 3 , some steering wheel products have different designs, so the inner edge contours of different steering wheel products are not the same. In order to enable the inner cutting mechanism 3 to meet the cutting requirements of the inner edge contours of various steering wheels.

[0079] The displacement assembly 31 provided by the embodiment includes a lifting linear module 311, a first horizontal linear module 312, and a second horizontal linear module 313. The lifting linear module 311 is arranged on the rack 1. The first horizontal linear module 312 is connected with the lifting linear module 311. The second horizontal linear module 313 is arranged on the first horizontal linear module 312. The movement output directions of the first horizontal linear module 312 and the second horizontal linear module 313 are perpendicular to each other. The lifting linear module 311 is used to drive the first horizontal linear module 312 and the second horizontal linear module 313 to move up and down. The first laser emitter 32 is arranged on the second horizontal linear module 313.

[0080] Specifically, the first horizontal linear module 312, the second horizontal linear module 313, and the lifting linear module 311 are all synchronous belt modules or motor linear modules. All of them have a sliding table capable of outputting reciprocating displacement movement. The specific structure of the linear module is a prior art, which will not be described in detail here.

[0081] For the convenience of description, a spatial rectangular coordinate system is established here, including x-axis and y-axis for moving along the horizontal direction, and z-axis for moving along the vertical direction. When the displacement assembly 31 is installed, first, the lifting linear module 311 is installed vertically on the rack 1, and at this time, the sliding table of the lifting linear module 311 can output reciprocating lifting movement; in addition, the first horizontal linear module 312 is installed horizontally on the sliding table of the lifting linear module 311, and the sliding table displacement direction of the first horizontal linear module 312 is consistent with the x-axis; on this basis, the second horizontal linear module 313 is arranged on the sliding table of the first horizontal linear module 312, and the sliding table of the second horizontal linear module 313 reciprocates along the y-axis direction, and the first laser emitter 32 is installed at the sliding table of the second horizontal linear module 313. Under the cooperation of the lifting linear module 311, the first horizontal linear module 312 and the second horizontal linear module 313, the base can drive the first laser emitter 32 to realize flexible adjustment in three-dimensional space.

[0082] Referring to Figure 4 and Figure 5 In some embodiments, the outer cutting mechanism 4 comprises a rotating assembly 41 and a second laser cutter 42. The rotating assembly 41 is arranged on the rack 1 and adjacent to the supporting mechanism 2, and the second laser cutter 42 is connected with the rotating assembly 41. The rotating assembly 41 is used to drive the second laser cutter 42 to rotate along the outer periphery of the steering wheel, more specifically, the rotating assembly 41 is used to drive the second laser cutter 42 to move around the outer periphery of the supporting mechanism 2, and at this time, the second laser cutter 42 is used to emit a vertically upward laser beam, thereby being able to cut the scrap edge outside the steering wheel.

[0083] In some embodiments, the rotating assembly 41 comprises a sliding seat 411, a rotating motor 412 and a rotating gear 413, and the rack 1 has an annular sliding groove 11. Specifically, the annular sliding groove 11 is located at the platform of the rack 1, and the annular sliding groove 11 has a circular profile and surrounds the outer periphery of the supporting mechanism 2, and the sliding seat 411 is slidingly arranged in the annular sliding groove 11. At this time, under the guidance of the annular sliding groove 11, the sliding seat 411 can displace around the supporting mechanism 2; the second laser cutter 42 is connected with the sliding seat 411, and in the process of the sliding seat 411 displacing around the supporting mechanism 2, the second laser cutter 42 is driven to move around the outer periphery of the steering wheel.

[0084] It can be understood that the specific structure of the second laser cutter 42 is similar to that of the first laser emitter 32, and the specific structure of the second laser cutter 42 will not be described here. In addition, the second laser cutter 42 can be directly connected to the sliding seat 411, or the second laser cutter 42 can be indirectly connected to the sliding seat 411 through other components. The specific arrangement of the second laser cutter 42 is not limited here, and any arrangement of the second laser cutter 42 on the sliding seat 411 should be included in the technical scope of the present application.

[0085] At the same time, the groove wall of the annular chute 11 has a plurality of driving teeth 12 arranged in sequence. Generally, the driving teeth 12 are located at a gear ring, the gear ring is matched with the profile of the annular chute 11, and the gear ring is fixedly arranged on the groove wall of the annular chute 11, so that the driving teeth 12 are arranged on the groove wall of the annular chute 11.

[0086] On this basis, the rotating motor 412 is arranged on the sliding seat 411. Generally, the rotating motor 412 is fixedly arranged on the sliding seat 411, the sliding seat 411 is provided with a vertical extension avoiding hole, the output shaft of the rotating motor 412 extends into the annular chute 11 through the avoiding hole, and the rotating gear 413 is arranged on the output shaft of the rotating motor 412. Specifically, the rotating gear 413 is fixedly arranged on the output shaft of the rotating motor 412, and the rotating gear 413 is engaged with the driving teeth 12.

[0087] Based on the above arrangement, by starting the rotating motor 412, the rotating motor 412 drives the gear to rotate. Under the condition that the gear and the driving teeth 12 are engaged with each other, the sliding seat 411 is pushed to move around the outer periphery of the steering wheel. In this process, since the second laser cutter 42 emits a vertical upward laser beam, the waste edge of the outer periphery of the steering wheel can be cut, and the effect of accurately removing the waste edge of the outer periphery of the steering wheel is achieved.

[0088] Further, different steering wheels have different designs, so the outer periphery profiles of different steering wheel products are different. When the outer periphery waste edge of different steering wheel products is cut and removed, the profile is uncertain, and the outer cutting mechanism 4 is difficult to adapt to different cutting paths. Based on this, in order to realize the function of cutting the outer periphery waste edge of the steering wheel product with different outer periphery profiles, the cutting mechanism provided by the embodiment of the present application further comprises a fine adjustment assembly 43, and the second laser cutter 42 is indirectly arranged on the sliding seat 411 through the fine adjustment assembly 43.

[0089] Reference Figure 5The fine adjustment assembly 43 comprises a mounting base 431, a lead screw 432, a connecting base 433 and a fine adjustment motor 434. The mounting base 431 is in the form of a long plate in this embodiment, is horizontally arranged, and is fixedly arranged on the top of the sliding base 411, and is connected with the rotating assembly 41. In addition, the length direction of the mounting base 431 is consistent with the radius of the annular sliding groove 11. The mounting base 431 has a linear sliding groove therein, which is arranged on the top of the mounting base 431 in a recessed manner from outside to inside, and extends along the length direction of the mounting base 431, so that the extension direction of the linear sliding groove is consistent with the extension direction of the sliding groove.

[0090] The lead screw 432 is rotatably arranged in the mounting base 431 and located in the linear sliding groove. Specifically, the lead screw 432 is located in the linear sliding groove, and both ends of the lead screw 432 are rotatably arranged in the mounting base 431 through bearing seats. The lead screw 432 can rotate relative to the mounting base 431. The connecting base 433 is slidably arranged in the linear sliding groove, and the lead screw 432 is connected with the connecting base 433. Specifically, a threaded hole is arranged through the connecting base 433, and the lead screw 432 is arranged through the threaded hole and is threadedly connected with the threaded hole. The second laser cutting device 42 is arranged on the connecting base 433. Specifically, the second laser cutting device 42 is fixedly arranged on the connecting base 433.

[0091] Further, the fine adjustment motor 434 is arranged in the mounting base 431 and connected with the lead screw 432. Specifically, the fine adjustment motor 434 is fixedly arranged in the mounting base 431, and the output shaft of the fine adjustment motor 434 is connected with the lead screw 432 through a shaft coupling. The fine adjustment motor 434 can be a servo motor, which can output positive and negative torques and accurately output a rotation angle. The fine adjustment motor 434 can be used to drive the lead screw 432 to rotate in the positive and negative directions. During the rotation of the lead screw 432, the connecting base 433 is pushed to move towards or away from the steering wheel, so that the connecting base 433 drives the second laser cutting device 42 to move towards or away from the steering wheel.

[0092] Based on the above arrangement, by controlling the distance between the second laser cutting device 42 and the steering wheel, the second laser cutting device 42 can accurately fit the specific profile of the outer periphery of the steering wheel and continuously cut the scrap edge during the movement around the steering wheel according to the profile of the steering wheel. The scrap edge cutting demand of the steering wheel with different outer edge profiles can be met, and the problem of difficult adaptation to multiple different steering wheel products is solved, and the versatility of the equipment is optimized and improved.

[0093] Further, referring back to Figure 1The laser cutting device provided by the embodiment further comprises a first camera module 5 and a control system. The first camera module 5 is arranged on the rack 1 and located directly above the supporting mechanism 2, and is used to shoot the steering wheel placed on the supporting mechanism 2 and obtain image information.

[0094] Specifically, the first camera module 5 is a CCD first camera module 5, which can shoot images and generate image information. The first camera module 5 is fixedly installed on the top of the rack 1 and arranged vertically downward. Before shooting the images, the displacement mechanism drives the first laser emitter 32 to move away from the steering wheel, so as to obtain complete and clear shooting images.

[0095] On this basis, the control system has a receiving end and an output end. The receiving end is connected with the first camera module 5, and the sending end is connected with the inner cutting mechanism 3 and the outer cutting mechanism 4 respectively. The control system is used to accept the image information and convert it into control signals, and send the control signals to the inner cutting mechanism 3 and the outer cutting mechanism 4 respectively, so that the inner cutting mechanism 3 and the outer cutting mechanism 4 perform cutting actions along the predetermined trajectories respectively.

[0096] Specifically, the control system mainly comprises a computer device and a PLC controller. The computer device and the PLC controller have receiving ends and output ends respectively. The receiving end of the computer device constitutes the receiving end of the control system, and the computer device is electrically connected with the first camera module 5. The output end of the computer device is electrically connected with the receiving end of the PLC controller. The output end of the PLC controller constitutes the output end of the control system, and the output end of the PLC controller is electrically connected with the inner cutting mechanism 3 and the outer cutting mechanism 4 respectively.

[0097] Based on the above arrangement, after the first camera module 5 obtains the image information, the image information is sent to the receiving end of the computer device. The computer device has the function of processing image information, can obtain the inner edge trajectory information and the outer edge trajectory information of the steering wheel through the processor, generate the inner edge cutting trajectory signal based on the inner edge trajectory information, and generate the outer edge cutting trajectory signal based on the outer edge trajectory information. Then, the computer device sends the inner edge cutting trajectory signal and the outer edge cutting trajectory signal to the receiving end of the PLC controller. The PLC controller generates corresponding control signals based on the inner edge cutting trajectory signal and the outer edge cutting trajectory signal, and sends the control signals to the inner cutting mechanism 3 and the outer cutting mechanism 4 through the output end, so as to control the inner cutting mechanism 3 and the outer cutting mechanism 4 to perform waste edge cutting processing on the inner and outer sides of the steering wheel along the specific trajectory or path, realize automatic recognition cutting action, and significantly optimize and improve the cutting efficiency and precision.

[0098] Further, in some embodiments, the output end of the control system can also be electrically connected with the locking mechanism. Specifically, a proximity sensor can be arranged on the positioning column 22, and the proximity sensor is connected with the receiving end of the control system. When the steering wheel is placed on the positioning column 22, the proximity sensor generates a proximity signal and sends it to the control system. The control system generates a control signal based on the proximity signal and sends it to the locking assembly 23, thereby controlling the locking assembly 23 to lock the steering wheel, realizing the automatic locking action of the steering wheel, so as to maintain the structural stability of the steering wheel.

[0099] Further, referring to Figure 6 The laser cutting device provided by the embodiment of the present application further comprises a mechanical hand 6 arranged on the rack 1. Generally, the mechanical hand 6 is fixedly arranged on the rack 1, and the mechanical hand 6 is arranged adjacent to the supporting mechanism 2, the inner cutting mechanism 3 and the outer cutting mechanism 4. The mechanical hand 6 is used to grab the steering wheel from the supporting mechanism 2 or take the steering wheel out of the supporting mechanism 2, so as to realize the automatic feeding and discharging action of the steering wheel. Generally, the mechanical hand 6 can adopt a six-axis mechanical hand 6 to obtain flexible movement freedom, so as to further grab various special-shaped steering wheel structures.

[0100] Further, a transmission module 7 is further included, which mainly comprises a chain assembly line 71 and an angle adjusting assembly 72. The angle adjusting assembly 72 is in multiple groups, and the multiple groups of angle adjusting assemblies 72 are sequentially and spacedly arranged along the length direction of the chain assembly line 71. Each angle adjusting assembly 72 can individually store one steering wheel, and the angle adjusting assembly 72 can drive the steering wheel to horizontally rotate, so as to adjust the relative angle of the steering wheel when it is grabbed by the mechanical hand 6.

[0101] It can be understood that the specific shape of the inner wall of the hole of different steering wheel products can be different, such as different steering wheels having protrusions or groove structures with different position distributions, or having different sizes and abutting points. Therefore, the fitting angle of the locking block 233 and the inner hole of different steering wheels is different. Based on this, in order to enable the locking block 233 to be fitted with the protrusions or groove structures of different steering wheel products, the angle adjusting angle is started to drive the steering wheel to rotate and adjust, so that the mechanical hand 6 can grab the same type of steering wheel at a specific angle during the feeding process, thereby facilitating the mechanical hand 6 to accurately place the steering wheel on the supporting mechanism 2 at a preset angle. At this time, by accurately controlling the relative angle of the positioning column 22 and the steering wheel during insertion, the locking block 233 can be accurately fitted in different inner holes of different steering wheels. Correspondingly, the specific numerical parameters of the preset angle value of the feeding line can also be adjusted according to different steering wheel products, so that different steering wheels can be grabbed by the mechanical hand 6 to the supporting mechanism 2 at a suitable insertion angle, and finally the steering wheel can be accurately fitted with the locking assembly 23.

[0102] In one embodiment, the angle adjusting assembly 72 comprises a bracket 721, an angle motor 722 and a rotating disc 723, the bracket 721 is fixedly arranged at the sliding table of the chain conveyor 71, the angle motor 722 is fixedly arranged on the bracket 721, the rotating disc 723 is horizontally arranged and fixedly connected with the angle motor 722, the angle motor 722 adopts a speed reducer motor to output accurate angle control action, and the angle motor 722 is connected with the control system, the control system can control the angle output action of the angle motor 722, on this basis, the rotating disc 723 is fixedly connected with the output shaft of the angle motor 722, and the rotating disc 723 is provided with a jig element on the top for placing the steering wheel, the jig element plays a role of primary positioning of the steering wheel.

[0103] It can be understood that the structure of the jig element is similar to the top structure of the positioning column 22, which will not be described in detail here. Based on the above arrangement, the angle motor 722 is started to drive the rotating disc 723 to rotate, and finally the jig element drives the steering wheel to rotate for adjustment.

[0104] Further, in other embodiments, another camera module can be arranged above the conveying module 7, which is defined as a second camera module (not shown in the figure), the second camera module is used to take pictures of the steering wheel placed on the angle adjusting assembly 72 to obtain image information, and the second camera module is also connected with the control system, at this time, the obtained image information is sent to the control system for analysis to obtain the angle of the steering wheel that needs to be adjusted and the corresponding control signal, the working principle of the second camera module and the control system is similar to that of the first camera module 5 and the control system, which will not be described here; at this time, the control signal is sent to the angle adjusting assembly 72 to realize the automatic deviation correction function of the steering wheel before feeding, and the feeding efficiency and accuracy can be further optimized and improved.

[0105] So far, the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
