Motor magnetic sheet feeding device and method

Abstract

The application discloses a motor magnetic sheet feeding device and a feeding method. Magnetic sheets are sequentially stacked in a feeding guide groove of a stock bin. After a second driving slide rail drives a pushing plate to align with the rear end of the feeding guide groove, a third driving slide rail drives the pushing plate to sequentially push the magnetic sheets in the feeding guide groove from the rear end forward. An elastic clamping mechanism is arranged at the outlet position of the front end of the feeding guide groove. The pushed-out magnetic sheets are clamped by the elastic clamping mechanism. Due to the pushing action of the pushing plate, the magnetic sheets in the feeding channel are continuously pushed into the discharge channel. After the magnetic sheets are completely pushed into the discharge channel, the lifting block moves upward with the magnetic sheets in the discharge channel under the pushing of a lifting cylinder until the upper end of the magnetic sheets is pushed out to the outside of the discharge channel. Then, the external material using mechanism can take away the magnetic sheets. The feeding device adopts a full-automatic process, has high working efficiency, can stably continuously feed the external material using mechanism, and thus meets the production requirements on site.

[0002] An electric motor is a drive component assembled from parts such as a motor housing, stator, and rotor. The rotor contains magnetic plates, which are plate-shaped and approximately 3mm-20mm in length and width.

[0003] In the current motor production process, the handling of magnetic sheets relies on manual labor, which is inefficient and inconvenient. Although there are some feeding devices that can transport magnetic sheets, they are not efficient and cannot adapt to large-scale production processes. Summary of the Invention

[0004] This application provides a feeding device and method for motor magnetic sheets, which can continuously and orderly feed materials to the material-using mechanism and has high working efficiency.

[0005] In a first aspect, this application discloses a feeding device for motor magnetic sheets, comprising:

[0006] The support mechanism includes a worktable and a first drive slide rail, the first drive slide rail being disposed on the worktable and the sliding direction of the first drive slide rail being configured as a first direction;

[0007] The hopper mechanism includes a hopper base and a hopper; the hopper base is mounted on a first drive slide rail; the hopper is mounted on the hopper base and the hopper is provided with a feeding guide chute along a first direction;

[0008] An elastic clamping mechanism is located at the outlet of the feeding guide chute and is used to clamp the motor magnetic sheet;

[0009] The feeding mechanism includes a second drive slide rail, a third drive slide rail, a first sliding seat, and a feeding plate; the second drive slide rail is disposed on the third drive slide rail, the sliding direction of the second drive slide rail is configured as a second direction, and the sliding direction of the third drive slide rail is configured as a first direction; the first sliding seat is disposed on the second drive slide rail; the feeding plate is disposed on the first sliding seat, and the feeding plate can move in the feeding guide groove along the first direction under the drive of the third drive slide rail;

[0010] The receiving mechanism includes a second sliding seat, a receiving base, and a fourth drive slide rail; the fourth drive slide rail is disposed on one side of the worktable, the second sliding seat is disposed on the fourth drive slide rail, and the sliding direction of the fourth drive slide rail is configured as a second direction; the receiving base is disposed on the second sliding seat, and the receiving base is provided with a connected discharge channel and a feed channel, the discharge channel is disposed along a third direction, and the feed channel is disposed along a first direction; under predetermined conditions, the feed channel can correspond to the outlet of the feeding guide in the first direction;

[0011] The lifting mechanism includes a lifting cylinder and a lifting block; the lifting cylinder is mounted on a second sliding seat, and the extension and retraction direction of the lifting cylinder is configured as a third direction; the lifting block is slidably mounted in the discharge channel along the third direction, and the lifting block is connected to the extension and retraction end of the lifting cylinder.

[0012] Secondly, this application discloses a method for feeding motor magnetic sheets, including:

[0013] Step S1: The second drive slide rail drives the first sliding seat and the pusher plate to move in the second direction until the pusher plate corresponds to the feeding guide groove of the hopper in the first direction;

[0014] Step S2: The third drive slide rail drives the pusher plate to move, and the pusher plate pushes the material to move in the first direction for a preset process, so that the material passes through the outlet of the feeding guide and the feeding channel in sequence and enters the discharge channel.

[0015] Step S3: The lifting block of the lifting mechanism moves upward, lifting the material in the discharge channel upward until at least a portion of the material is lifted to the outside of the discharge channel;

[0016] Step S4: The external material feeding mechanism removes the material from the outside of the discharge channel;

[0017] Step S5: Repeat steps S2 to S4 until all the material in the current hopper has been pushed out. Then return to step S1 and use the second drive slide rail to drive the pusher plate to correspond with the feeding guide of the next hopper.

[0018] In step S2, after the pusher plate pushes the material for a preset process, the pusher plate immediately retracts along the first direction by a distance of not less than one-quarter of the preset process.

[0019] The feeding device and feeding method for the motor magnetic sheet of this application have at least the following beneficial effects:

[0020] (1) In the feeding device of this application, magnetic sheets are stacked in the feeding guide groove of the hopper in sequence. Then, the first drive slide rail drives the hopper base and the hopper back to the working position. The second drive slide rail drives the pusher plate to align with the rear end of the feeding guide groove.

An elastic clamping mechanism is set at the outlet position of the front end of the feeding guide groove. The pushed magnetic sheets are elastically clamped to ensure that they can be stably pushed into and transitioned into the feed channel of the receiving seat. Due to the pushing action of the pusher plate, the magnetic sheets in the feed channel are continuously pushed into the discharge channel. At this time, the lifting block carries the magnetic sheets in the discharge channel. After the magnetic sheets are completely pushed into the discharge channel, the lifting block moves upward with the magnetic sheets in the discharge channel under the push of the lifting cylinder until the upper end of the magnetic sheets is pushed out to the outside of the discharge channel. Then the external feeding mechanism can take away the magnetic sheets. The feeding device of this application adopts a fully automatic process, has high working efficiency, and can stably and continuously feed materials to external material-using institutions, thereby meeting the production needs on site.

[0021] (2) In the feeding method of this application, the magnetic sheets in the hopper are pushed out in sequence to achieve effective feeding. After the magnetic sheets in the current hopper are fed, the operation is repeated for the next hopper to achieve continuous feeding. In addition, in this application, after the pusher plate pushes the material to move for a preset process, it immediately retreats a certain distance to avoid the magnetic sheets in the feeding guide groove being deformed by excessive compression.

[0049] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0051] To facilitate understanding of the technical solutions of the embodiments of this application, some situations in the industry will be explained first.

[0052] The rotor of an electric motor is generally made of silicon steel, and it also contains magnetic plates (magnetic steel sheets), which are typically plate-shaped. In existing technologies, due to the small size of the magnetic plates and the lack of efficient feeding devices, the actual production efficiency is too low, thus hindering the improvement of motor production efficiency.

[0053] This application discloses a feeding device and feeding method for motor magnetic sheets, which can achieve efficient feeding of magnetic sheets. First, the feeding device in this application will be introduced.

[0054] like Figures 1 to 3 As shown, a feeding device for motor magnetic sheets includes a support mechanism 1, a hopper mechanism 2, an elastic clamping mechanism 3, a pushing mechanism 4, a receiving mechanism 5, and a lifting mechanism 6.

[0055] The support mechanism 1 includes a worktable 11 and a first drive slide rail 12. The first drive slide rail 12 is disposed on the worktable 11, and the sliding direction of the first drive slide rail 12 is configured as a first direction.

[0056] The hopper mechanism 2 includes a hopper base 21 and a hopper 22; the hopper base 21 is disposed on the first drive slide rail 12; the hopper 22 is disposed on the hopper base 21, and the hopper 22 is provided with a feeding guide groove 22a along the first direction;

[0057] The elastic clamping mechanism 3 is disposed at the outlet 22b of the feeding guide groove and is used to clamp the motor magnetic sheet;

[0058] The feeding mechanism 4 includes a second drive slide rail 41, a third drive slide rail 42, a first sliding seat 43, and a feeding plate 44. The second drive slide rail 41 is disposed on the third drive slide rail 42, and the sliding direction of the second drive slide rail 41 is configured as a second direction, while the sliding direction of the third drive slide rail 42 is configured as a first direction. The first sliding seat 43 is disposed on the second drive slide rail 41. The feeding plate 44 is disposed on the first sliding seat 43, and the feeding plate 44 can move along the first direction in the feeding guide groove 22a under the drive of the third drive slide rail 42.

[0059] The receiving mechanism 5 includes a second sliding seat 51, a receiving seat 52, and a fourth drive slide rail 53. The fourth drive slide rail 53 is disposed on one side of the worktable 11, and the second sliding seat 51 is disposed on the fourth drive slide rail 53. The sliding direction of the fourth drive slide rail 53 is configured as a second direction. The receiving seat 52 is disposed on the second sliding seat 51 and is provided with a connected discharge channel 52a and a feed channel 52b. The discharge channel 52a is disposed along a third direction, and the feed channel 52b is disposed along a first direction. Under predetermined conditions, the feed channel 52b can correspond to the outlet 22b of the feeding guide in the first direction.

[0060] The lifting mechanism 6 includes a lifting cylinder 61 and a lifting block 62; the lifting cylinder 61 is disposed on the second sliding seat 51, and the extension and retraction direction of the lifting cylinder 61 is configured as the third direction; the lifting block 62 is slidably disposed in the discharge channel 52a along the third direction, and the lifting block 62 is connected to the extension and retraction end of the lifting cylinder 61.

[0061] Among them, the first direction, the second direction, and the third direction intersect each other perpendicularly, and the third direction is configured as the height direction.

[0062] The workbench 11 is set on the ground or work surface and serves to support other components and structures.

[0063] The hopper 22 has a through feeding guide 22a along the first direction. The material to be conveyed (i.e., magnetic sheets) is stacked in the feeding guide 22a. An opening of the feeding guide 22a near the receiving seat 52 is configured as the outlet 22b of the feeding guide 22a.

[0064] The elastic clamping mechanism 3 is located at the outlet 22b of the feeding guide groove, and can elastically clamp the magnetic sheet pushed out from the feeding guide groove 22a.

[0065] The pushing mechanism 4 is used to push the magnetic sheet in the feeding guide 22a from the outlet 22b of the feeding guide 22a to the discharge channel 52a of the receiving seat 52.

[0066] Among them, the fourth drive slide rail 53 of the receiving mechanism 5 can drive the receiving seat 52 to slide in the second direction. After the magnetic sheet in the current hopper 22 is pushed out, the fourth drive slide rail 53 can drive the receiving seat 52 to slide along the second direction to the next hopper 22 position, so as to continuously receive the pushed-out magnetic sheet.

[0067] Among them, the discharge channel 52a is a channel opened along the third direction. The lifting block 62 is slidably set in the discharge channel 52a. Driven by the lifting cylinder 61, the lifting block 62 can slide in the discharge channel 52a along the third direction, thereby pushing the magnetic sheet out from the discharge channel 52a.

[0068] In the feeding device of this embodiment, magnetic sheets are stacked sequentially in the feeding guide 22a of the hopper 22. Then, the first drive slide rail 12 drives the hopper base 21 and the hopper 22 back to the working position. The second drive slide rail 41 drives the pusher plate 44 to align with the rear end of the feeding guide 22a. The third drive slide rail 42 drives the pusher plate 44 to push the magnetic sheets in the feeding guide 22a forward sequentially from the rear end. An elastic clamping mechanism 3 is provided at the outlet position of the front end of the feeding guide 22a. The pushed magnetic sheets are elastically clamped to ensure that they can be pushed forward. The magnetic sheet is stably pushed into and transitions into the feed channel 52b of the receiving seat 52. Due to the pushing action of the pusher plate 44, the magnetic sheet in the feed channel 52b is continuously pushed into the discharge channel 52a. At this time, the lifting block 62 supports the magnetic sheet in the discharge channel 52a. After the magnetic sheet is completely pushed into the discharge channel 52a, under the push of the lifting cylinder 61, the lifting block 62 moves upward with the magnetic sheet in the discharge channel 52a until the upper end of the magnetic sheet is pushed out to the outside of the discharge channel 52a. Then the external feeding mechanism can remove the magnetic sheet. The feeding device of this embodiment adopts a fully automatic process, has high working efficiency, and can stably and continuously feed materials to the external feeding mechanism, thereby meeting the production needs on site.

[0069] Preferred, such as Figures 4 to 7 As shown, the first drive slide rail 12 is arranged in a one-to-one correspondence with the hopper mechanism 2, and multiple hopper mechanisms 2 are spaced apart along the second direction; the hopper mechanism 2 includes multiple hoppers 22 spaced apart along the second direction on the hopper base 21, and the hopper base 21 is provided with a positioning pin 211; the hopper base 21 is provided with a positioning hole 22c that cooperates with the positioning pin 211, and the hopper 22 and the hopper base 21 are magnetically connected.

[0070] Among them, such as Figure 4 As shown, a support plate 13 is provided on the workbench 11 of the support mechanism 1. The support plate 13 is slidably disposed on the upper plane of the workbench 11 via a first guide rail 14, and the sliding direction of the first guide rail 14 is configured as a first direction.

[0071] Among them, such as Figure 4 As shown, a drawer baffle 15 is provided at one end of the support plate 13 away from the receiving seat 52 along the first direction. The drawer baffle 15 is used to block the hopper mechanism 2. The first drive slide rail 12 is provided on the upper surface of the support plate 13.

[0072] Among them, such as Figure 4 As shown, the support plate 13, the first guide slide rail 14, the hopper mechanism 2 and the first drive slide rail 12 are arranged in a one-to-one correspondence. In this embodiment of the application, two support plates 13 and two hopper mechanisms 2 are illustrated.

[0073] Among them, such as Figure 4 As shown, two first drive slide rails 12 are spaced apart on two support plates 13 along the second direction.

[0074] Among them, such as Figure 5 and Figure 6 As shown, the hopper mechanism 2 includes a hopper base 21 and multiple hoppers 22. The number of hoppers 22 is selected according to the actual situation. Multiple hoppers 22 are spaced apart on the hopper base 21 along the second direction, and each hopper 22 is provided with a feeding guide groove 22a for placing magnetic sheets.

[0075] Among them, such as Figure 7 As shown, a positioning pin 211 is provided on the hopper base 21, and a positioning hole 22c is provided on the bottom surface of the hopper 22. When the hopper 22 is installed on the hopper base 21, the positioning pin 211 is inserted into the positioning hole 22c.

[0076] Among them, such as Figure 7 As shown, the hopper base 21 and the hopper 22 are magnetically connected. For example, the hopper base 21 is provided with a magnetic post 212, and the bottom surface of the hopper 22 is provided with a magnetic hole 22d. When the hopper 22 is installed on the hopper base 21, the magnetic post 212 is inserted into the magnetic hole 22d, and the magnetic post 212 and the magnetic hole 22d are magnetically attracted to each other.

[0077] In this embodiment, multiple hopper mechanisms 2 are provided on the workbench 11, which facilitates the temporary storage of a large number of magnetic sheets for use by the material-using mechanism. Furthermore, in this embodiment, the hopper base 21 and the hopper 22 are detachable, allowing for quick replacement of the hopper 22 and replenishment of materials. The material replacement process is as follows: First, the first drive slide rail 12 drives the hopper mechanism 2 to move along the first direction toward the drawer baffle 15 until it touches the drawer baffle 15 and stops. Since the drawer baffle 15 is limited by a vertically retractable latch (not shown), it will not move after being touched by the hopper mechanism 2. After the operator arrives at the replacement position, they retract the latch and manually pull the drawer baffle 15 and the support plate 13 together along the first direction, thereby horizontally pulling out the hopper 22 on the support plate 13. Finally, the operator places the new hopper 22 on the hopper base 21 and uses the first drive slide rail 12 to drive the hopper mechanism 2 back to the working position, thus completing the material replacement. It should be noted that the drawer baffle 15 prevents the hopper 22 from being directly pushed out to the outside of the device under the drive of the first drive slide rail 12, thus avoiding injury to passing personnel. Specifically, when replacing the hopper 22, the hopper 22 and the hopper base 21 are initially positioned using the positioning pin 211 and the positioning hole 22c, and then a secondary positioning is achieved using the cooperation of the magnetic post 212 and the magnetic suction hole 22d. The structure is simple and reliable, and performs well in practical applications.

[0078] Preferred, such as Figures 5 to 7 As shown, the elastic clamping mechanism 3 includes two elastic clamping components 31, which are symmetrically arranged on both sides of the outlet 22b of the feeding guide groove along the second direction. Each elastic clamping component 31 includes a spring stop 311, a clamping block 312, and a first elastic element 313. The spring stop 311 is disposed on the hopper 22, and the clamping block 312 is rotatably disposed on the outlet 22b of the feeding guide groove. The two ends of the first elastic element 313 are respectively connected to the spring stop 311 and the clamping block 312.

[0079] Among them, such as Figure 5 As shown, each hopper 22 is provided with an elastic clamping mechanism 3 at its outlet position. Each elastic clamping mechanism 3 includes two elastic clamping components 31, which can clamp the magnetic sheet at the outlet position from both sides.

[0080] Among them, such as Figure 6As shown, the elastic clamping assembly 31 includes a spring baffle that is vertically fixed on the side wall of the hopper 22. The outlet 22b of the feeding guide groove is provided with a mounting groove that corresponds one-to-one with the clamping block 312. The clamping block 312 is horizontally rotatable in the mounting groove. The two ends of the first elastic element 313 are respectively connected to the spring baffle 311 and the clamping block 312. The first elastic element 313 is configured as a spring.

[0081] In this embodiment, the first elastic element 313 can provide elastic force to the clamping blocks 312, causing the two clamping blocks 312 to tend to clamp towards the center of the feeding guide groove 22a. When the magnetic sheet in the feeding guide groove 22a is pushed, the two clamping blocks 312 elastically clamp the magnetic sheet from both sides, ensuring that the magnetic sheet transitions stably and orderly into the receiving seat 52, thereby ensuring the stable operation of the device and avoiding the phenomenon of mechanism jamming. In some other embodiments, the elastic clamping mechanism 3 can also be a component with clamping function such as a cylinder finger, but the elastic clamping mechanism 3 in this embodiment adopts a non-driving force elastic clamping, which achieves better results.

[0082] Preferred, such as Figure 7 As shown, the hopper 22 is also provided with a guide cover plate 221, the guide cover plate 221 has a guide slope 2211, the guide slope 2211 has a preset angle θ with the horizontal plane, and the projection of the guide slope 2211 in the third direction covers at least part of the outlet 22b of the feeding guide groove; the preset angle θ is in the range of 10 degrees to 40 degrees.

[0083] Among them, such as Figure 7 As shown, the guide cover 221 is located above the outlet 22b of the feeding guide groove. The lower side of the guide cover 221 has a guide slope 2211. The guide slope 2211 is inclined relative to the horizontal plane, and the side of the guide slope 2211 near the receiving seat 52 is configured as the relatively lower side.

[0084] Among them, such as Figure 7 As shown, the guide slope 2211 has a preset angle θ with the horizontal plane. The preset angle θ ranges from 10 degrees to 25 degrees, for example, 10 degrees, 15 degrees, and 20 degrees.

[0085] In this embodiment, since multiple magnetic sheets are stacked in the feeding guide groove 22a along the first direction, when the pusher plate 44 at the rear end pushes the magnetic sheets from the rear end, some magnetic sheets in the feeding guide groove 22a may be squeezed and tilted upwards. Therefore, in order for the magnetic sheets to smoothly transition into the receiving seat 52, this embodiment provides a guide cover plate 221 at the outlet 22b of the feeding guide groove. The guide slope 2211 of the guide cover plate 221 is used to guide the tilted magnetic sheets downwards to be flush with other magnetic sheets, so as to maintain the smooth transition of the magnetic sheets.

[0086] Preferred, such as Figures 8 to 10 As shown, the first sliding seat 43 of the pushing mechanism 4 includes a first mounting block 431, a second mounting block 432, a floating block 433, a second elastic element 434, and a third elastic element 435; the first mounting block 431 is disposed on the second drive slide rail 41; the second mounting block 432 is disposed on the first mounting block 431; the floating block 433 is slidably disposed on the first mounting block 431 along a first direction; the pushing plate 44 is disposed on the floating block 433; the two ends of the second elastic element 434 are respectively connected to the floating block 433 and the first mounting block 431; the two ends of the third elastic element 435 are respectively connected to the pushing plate 44 and the first mounting block 431; wherein, the extension and retraction directions of the second elastic element 434 and the second elastic element 435 are both configured in the first direction.

[0087] Among them, such as Figure 8 As shown, the pushing mechanism 4 includes a second drive slide rail 41, a third drive slide rail 42, a first sliding seat 43, and a pushing plate 44; as Figure 9 and Figure 10 As shown, the first sliding seat 43 includes a first mounting block 431, a second mounting block 432, a floating block 433, a second elastic element 434, and a third elastic element 435.

[0088] Among them, such as Figure 8 As shown, at least a portion of the third drive slide rail 412 is disposed on one side of the worktable 11 (one side along the second direction), and the other portion of the third drive slide rail 42 is disposed on the other side of the worktable 11.

[0089] Among them, such as Figure 8 As shown, the second drive slide rail 41 includes a gantry frame 411, a slide rail 412, a slider 413, and a clamping block 414; the two column ends of the gantry frame 411 are respectively connected to the two parts of the two third drive slide rails 42. The gantry frame 411 is driven to move in the first direction through the third drive slide rails 42, thereby causing the pusher plate 44 indirectly connected to the gantry frame 411 to push the material forward.

[0090] like Figure 10 As shown, a first machining surface 4111 is provided on the gantry frame 411, a slide rail 412 is horizontally provided on the first machining surface 4111, the length direction of the slide rail 412 is configured as a second direction, and a slider 413 is slidably provided on the slide rail 412; a clamping block 414 is provided on the gantry frame 411, and a second machining surface 4141 is provided on the clamping block 414. The second machining surface 4141 fits against the upper side wall of the slide rail 412, thereby pressing the slide rail 412. Multiple clamping blocks 414 are spaced apart on the gantry frame 411 along the second direction.

[0091] Among them, such as Figure 10As shown, the first mounting block 431 of the first sliding seat 43 is disposed on the slider 413 of the second drive slide rail 41, and the second mounting block 432 is horizontally connected to the side wall of the first mounting block 431.

[0092] Among them, such as Figure 10 As shown, the floating block 433 is slidably disposed on the lower side of the second mounting block 432. This sliding arrangement can be achieved by connecting the floating block 433 to the lower side of the second mounting block 432 via a second guide rail 436, as detailed in the prior art. The sliding direction of the floating block 433 is configured as a first direction.

[0093] Among them, such as Figure 10 As shown, the pusher plate 44 is fixedly installed on the lower side of the floating block 433, and the two ends of the multiple second elastic members 434 are respectively connected to the floating block 433 and the first mounting block 431; the two ends of the third elastic member 435 are respectively connected to the pusher plate 44 and the first mounting block 431, and both the second elastic members 434 and the third elastic member 435 are configured as springs.

[0094] In other embodiments, such as Figure 9 As shown, the first sliding seat 43 also includes a limiting block 437, which is disposed on the second mounting block 432, and at least a portion of the limiting block 437 can abut against the floating block 433 in a first direction, thereby limiting the floating block 433.

[0095] In this embodiment, when the gantry 411 drives the pusher plate 44 to move, the pusher plate 44 can abut against the magnetic sheet in the feeding guide groove 22a, thereby pushing the magnetic sheet forward. The third elastic member 435 can prevent the pusher plate 44 from rigidly abutting against the magnetic sheet, that is, the pusher plate 44 can elastically push the magnetic sheet, avoiding excessive pushing force from squeezing and deforming the magnetic sheet. At the same time, the pusher plate 44 is set on the slidable floating block 433. The floating block 433 and the second elastic member 434 can release the contact pressure between the pusher plate 44 and the magnetic sheet through elastic contraction and sliding cooperation, playing a secondary buffering effect. On the other hand, this embodiment also designs the second drive slide rail 41. The first machining surface 4111 on the gantry 411 and the second machining surface 4141 on the clamping block 414 ensure the horizontality of the slide rail 412 of the second drive slide rail 41, thereby improving the stability and motion accuracy of the structure.

[0096] Preferred, such as Figure 11 and Figure 12As shown, the receiving mechanism 5 further includes a transition block 54 disposed on the receiving seat 52; the upper top surface 542 of the transition block is configured as the lower bottom surface of the feeding channel 52b, and the outlet 22b of the feeding guide channel and the feeding channel 52b have a clearance H in a first direction, and at least a portion of the upper top surface of the transition block 54 is disposed within this clearance H. The clearance H is as follows: Figure 13 As shown, Figure 13 yes Figure 3 Enlarged view of point A in the middle.

[0097] Among them, such as Figure 12 As shown, the receiving seat 52 is located on one side of the outlet 22b of the feeding guide groove. The receiving seat 52 is mounted on the second sliding seat 51, which is mounted on the fourth drive slide rail 53. The fourth drive slide rail 53 can drive the second sliding seat 51 and the receiving seat 52 to slide in the second direction.

[0098] like Figure 13 As shown, since the receiving seat 52 needs to slide in the second direction, there will be a certain gap between the receiving seat 52 and the left end face of the hopper 22 after the receiving seat 52 is assembled. This gap is the aforementioned clearance H. This clearance is caused by assembly errors and structural design. The existence of this clearance results in a partially unsupported position when the magnetic sheet transitions from the hopper 22 to the receiving seat 52, which is not conducive to the transition of the magnetic sheet into the receiving seat 52. It should be noted that if the assembly accuracy and the structural processing and design accuracy are high enough, this clearance can theoretically be avoided. That is, theoretically, the receiving seat 52 can be tightly attached to the left end face of the hopper 22 after assembly. However, on the other hand, this undoubtedly increases the burden on manufacturing and assembly.

[0099] In this embodiment, to address the gap H between the receiving seat 52 and the hopper 22, a transition block 54 is designed. The upper top surface 542 of the transition block serves as the lower bottom surface of the feed channel 52b, and the upper top surface 542 extends at least partially towards the left end face of the hopper 22. This extended portion of the upper top surface can fill the gap between the hopper 22 and the receiving seat 52, allowing the magnetic sheet to smoothly transition into the receiving seat 52. In some cases, the transition block 54 is detachably mounted on the receiving seat 52, facilitating the replacement of transition blocks 54 of different specifications according to the size of the gap, to fill the gap between the receiving seat 52 and the hopper 22.

[0100] Preferred, such as Figure 14 and Figure 15As shown, the receiving mechanism 5 further includes a fourth elastic element 55; the transition block 54 is slidably disposed on the receiving seat 52 along the first direction, the fourth elastic element 55 is disposed between the receiving seat 52 and the transition block 54, and the extension and retraction direction of the fourth elastic element 55 is configured to be the first direction.

[0101] Among them, such as Figure 14 and Figure 15 As shown ( Figure 14 (The transition block is not shown in the figure). The transition block 54 has a guide hole 54a, and the receiving seat 52 has a threaded hole 52c. The threaded connector 56 passes through the guide hole 54a and is connected to the threaded hole 52c. Specifically, the threaded connector 56 is provided with a smooth section and a threaded section. The threaded section is connected to the threaded hole 52c, and the guide hole 54a is in sliding fit with the smooth section.

[0102] Among them, such as Figure 15 As shown, the fourth elastic element 55 is configured as a spring, and the number of the fourth elastic elements 55 is selected according to the actual situation. Along the first direction, the transition block 54 is provided with a first spring mounting groove 54b on the side facing the receiving seat 52, and the receiving seat 52 is provided with a corresponding second spring mounting groove 52d. The two ends of the fourth elastic element 55 are respectively located in the first spring mounting groove 54b and the second spring mounting groove 52d.

[0103] In this embodiment, the transition block 54 can be slightly displaced relative to the receiving seat 52 in the first direction (the displacement range is, for example, 2mm to 10mm). Then, the fourth elastic element 55 provides the transition block 54 with an elastic force that moves towards the hopper 22, so that the right side of the transition block 54 (i.e., the side facing away from the receiving seat 52) ​​can elastically fit against the left end face of the hopper 22, so that the upper top surface 542 of the transition block can directly fit against the bottom surface of the outlet 22b of the feeding guide channel. That is, by designing the fourth elastic element 55, the gap between the receiving seat 52 and the hopper 22 can be completely made up, and the problem of gaps in individual positions caused by the different sizes of the gaps between each hopper 22 and the receiving seat 52 can be avoided.

[0104] Preferred, such as Figure 15 As shown, the transition block 54 has a rounded corner 541 on one side along the second direction.

[0105] Among them, such as Figure 15 As shown, the transition block 54 has a first side and a second side in the second direction, and a third side and a fourth side in the first direction, with the fourth side configured to face the hopper 22. A rounded corner 541 is provided between the first and fourth sides, and between the second and fourth sides, of the transition block 54.

[0106] In the embodiments of this application, such as Figure 13 and Figure 15 As shown, since the transition block 54 protrudes relative to the receiving seat 52 along the first direction, and the receiving seat 52 needs to move in a staggered manner relative to the hopper 22 along the second direction, a rounded corner 541 is provided on the transition block 54 to make arc contact with the outermost hopper 22. This avoids interference between the transition block 54 and the outermost hopper 22, ensuring smooth operation of the receiving seat 52. In other embodiments, lubricating oil or other lubrication methods can be applied to the transition block 54 to further reduce friction between the transition block 54 and the hopper 22.

[0107] Preferred, such as Figure 16 As shown, the horizontal cross-sectional shape of the discharge channel 52a is T-shaped, and the horizontal cross-sectional shape of the lifting block 62 is T-shaped.

[0108] Among them, such as Figure 16 As shown, the receiving base 52 is provided with a discharge channel 52a and a feed channel 52b. The discharge channel 52a is provided to penetrate the entire receiving base 52 in a third direction. The feed channel 52b is at the same height as the outlet 22b of the feeding guide channel on the hopper 22. That is, the bottom surface of the feed channel 52b is at the same height as the bottom surface of the feeding guide channel 22a. One side of the feed channel 52b is connected to the discharge channel 52a, and the other side is configured as the inlet of the magnetic sheet.

[0109] Among them, such as Figure 16 As shown, the top view of the discharge channel 52a is T-shaped. The discharge channel 52a includes a first section and a second section that are connected. The second section is connected to one side of the feed channel 52b and is used to accommodate the magnetic sheet. The first section can be used to guide the lifting block 62.

[0110] Please refer to the following again. Figure 12 As can be seen, the lifting mechanism 6 in this embodiment includes a lifting cylinder 61, a lifting block 62, a push seat 63, and a third guide rail 64; the lifting cylinder 61 is mounted on the second sliding seat 51, and the extension end of the lifting cylinder 61 is provided with a push seat 63. The push seat 63 and the second sliding seat 51 are slidably connected by the third guide rail 64, and the sliding direction of the third guide rail 64 is configured as a third direction; the lifting block 62 is vertically fixed on the push seat 63, and at least a portion of the lifting block 62 extends into the discharge channel 52a.

[0111] The lifting block 62 is also T-shaped when viewed from above, and the outer periphery of the lifting block 62 fits into the inner periphery of the discharge channel 52a.

[0112] In this embodiment, the discharge channel 52a and the lifting block 62 are both T-shaped, which can ensure the stability and accuracy of the up-and-down movement of the lifting block 62.

[0113] The feeding device in this application embodiment also includes the following structure, such as Figure 16 As shown:

[0114] The first sensor 7 is mounted on the second sliding seat 51. The detection direction of the first sensor 7 is configured as the first direction. The first sensor 7 is used to detect whether there is still material (i.e., magnetic sheet) in the feeding guide trough 22a.

[0115] The second sensor 8 is installed on the receiving seat 52. The second sensor 8 is used to detect whether there is material in the feed channel 52b.

[0116] The third sensor 9 is located above the receiving seat 52. The detection direction of the third sensor 9 is configured as the second direction. The third sensor 9 is used to detect whether there is material outside the discharge channel 52a, that is, to detect whether the magnetic sheet is pushed to the outside of the discharge channel 52a. There are multiple third sensors 9, which are spaced apart along the third direction (height direction). The purpose of setting multiple third sensors 9 is to facilitate the selection of detection points according to the product specifications, thereby achieving product adaptation.

[0117] In the embodiments of this application, the first drive slide rail 12, the second drive slide rail 41, the third drive slide rail 42 and the fourth drive slide rail 53 are all structures that can slide autonomously. For example, they can be driven by drive components such as motors and cylinders to achieve autonomous sliding, as can be referred to in the prior art.

[0118] In this embodiment, the first guide rail 14, the second guide rail 436, and the third guide rail 64 are all sliding guide mechanisms that do not require autonomous sliding.

[0119] In addition, this application also discloses a method for feeding motor magnetic sheets, which uses the aforementioned feeding device and includes the following steps:

[0120] Step S1: The second drive slide rail 41 drives the first sliding seat 43 and the pusher plate 44 to move in the second direction until the pusher plate 44 corresponds to the feeding guide groove 22a of the hopper 22 in the first direction.

[0121] Step S2: The third drive slide rail 42 drives the pusher plate 44 to move. The pusher plate 44 pushes the material to move in the first direction for a preset process, so that the material passes through the outlet 22b of the feeding guide and the feeding channel 52b in sequence and enters the discharge channel 52a.

[0122] Step S3: The lifting block 62 of the lifting mechanism 6 moves upward to lift the material in the discharge channel 52a upward until at least a portion of the material is lifted to the outside of the discharge channel 52a.

[0123] Step S4: The external material feeding mechanism removes the material outside the discharge channel 52a;

[0124] Step S5: Repeat steps S2 to S4 until all the material in the current hopper 22 has been pushed out, then return to step S1 and drive the pusher plate 44 to correspond with the feeding guide 22a of the next hopper 22 via the second drive slide rail 41.

[0125] In step S2, after the pusher plate 44 pushes the material for a preset process, the pusher plate 44 immediately retracts along the first direction by a distance of not less than one-quarter of the preset process.

[0126] In the feeding method of this application embodiment, the magnetic sheets in the hopper 22 are pushed out in sequence to achieve effective feeding. After the magnetic sheets in the current hopper 22 are fed, the operation is repeated for the next hopper 22 to achieve continuous feeding. In this application embodiment, after the pusher plate 44 pushes the material to move for a preset process, it immediately retracts a certain distance to avoid the magnetic sheets in the feeding guide trough 22a being deformed due to excessive compression.

[0127] In step S1, the slider 413 of the second drive slide rail 41 drives the first sliding seat 43 and the pusher plate 44 to move in the second direction until the pusher plate 44 is aligned with the rear end of a certain feeding guide groove 22a; at the same time, the fourth drive slide rail 53 drives the second sliding seat 51 and the receiving seat 52 to move until the feeding channel 52b on the receiving seat 52 is aligned with the outlet 22b of this feeding guide groove in the first direction.

[0128] In step S2, after the pusher plate 44 is aligned, the third drive slide rail 42 drives the gantry frame 411 and the pusher plate 44 to move towards the hopper 22 along the first direction. When the pusher plate 44 touches a piece of material (i.e., a magnetic sheet) at the rear end of the feeding guide trough 22a, the pusher plate 44 continues to push along the first direction until it reaches a preset process and then stops pushing. The preset process can be understood as the distance that the pusher plate 44 continues to move along the first direction after touching the material. In other embodiments, the preset process is equal to the thickness of a material. After the pusher plate 44 pushes the material for a preset process, the pusher plate 44 immediately retracts along the first direction by a distance of not less than one-quarter of the preset process. In the embodiments of this application, it is preferred that the pusher plate 44 immediately retracts one-quarter of the preset process after pushing the material for a preset process. Here, "immediate retraction" can be understood as not exceeding 0.5 seconds.

[0129] As the pusher plate 44 advances, the material located at the outlet 22b of the feeding guide is pushed into the feed channel 52b of the receiving seat 52, and then enters the discharge channel 52a from the feed channel 52b.

[0130] In step S3, the telescopic end of the lifting cylinder 61 extends, driving the pusher 63 and the lifting block 62 to move upward. The upper end of the lifting block 62 pushes the material in the discharge channel 52a upward to the outside of the discharge channel 52a.

[0131] In step S4, the third sensor 9 above the receiving seat 52 detects that the material has been pushed out, and the third sensor 9 sends a signal to the external feeding mechanism, and the robot or other structure of the external feeding mechanism takes away the material above the receiving seat 52.

[0132] In step S5, if the first sensor 7 senses that the material in the current hopper 22 has been completely pushed, then return to step S1 and find the next hopper 22 with material to continue feeding.

[0133] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
