Description

Technical Field

[0001] This invention belongs to the field of automated production technology of motor magnets, and particularly relates to a high-performance neodymium iron boron magnet assembly line for precision micro motors. Background Technology

[0002] Miniature motors typically refer to motors with a diameter less than 160mm or a rated power less than 750mA. These precision micro-motors utilize high-performance neodymium iron boron magnets and are assembled on precision micro-motors. Precision micro-motors combine the small size and high precision of traditional micro-motors. For example, coreless motors, as typical compact micro-motors, possess outstanding energy-saving characteristics, sensitive and convenient control characteristics, and stable operation characteristics, demonstrating significant technological advancement. As highly efficient energy conversion devices, they represent the future development direction of electric motors in many fields.

[0003] Neodymium iron boron (NdFeB) magnets are high-performance magnets with excellent temperature characteristics, chemical stability, and high mechanical strength. Furthermore, NdFeB magnets possess high energy product and coercivity, and their saturation magnetic induction at room temperature is significantly higher than that of other permanent magnets (such as AlNiCo). Therefore, they are used for electrical excitation in miniaturized electromechanical devices requiring high performance.

[0004] The neodymium iron boron magnets in the motor can be either integrally circular or composed of multiple block-shaped neodymium iron boron magnet assemblies 100 (e.g. Figure 2 A ring-shaped structure composed of (e.g.) Figure 1 The magnet assembly 100 includes a magnet 102 and a first yoke 101 and a second yoke 103, respectively used for bonding and fixing to both sides of the magnet 102. In the prior art, the method for bonding the magnet body and the yoke sheets is as follows: the magnet 102 is manually fixed, glue is applied to the surface of the magnet 102 one by one using a glue gun, and then the first yoke 101 and the second yoke 103 are adhered to it. The positions of the first yoke 101 and the second yoke 103 are manually fine-tuned as needed. After the glue solidifies, the desired motor magnet is obtained.

[0005] The shortcomings of the existing technology are that the current production method, which mainly relies on manual assembly of motor magnet components, is not only inefficient, but also affects product quality due to the inability to provide accurate and reliable positioning of the magnet and yoke and uneven application of glue.

[0006] Therefore, it is necessary to provide a new precision micro-motor high-performance neodymium iron boron magnet assembly line to solve the above-mentioned technical problems. Summary of the Invention

[0007] (I) Technical problem to be solved: Based on this, the present invention provides a high-performance neodymium iron boron magnet assembly line for precision micro motors, which aims to solve the technical problems of poor product quality and low production efficiency in the existing method of assembling motor magnet components by manual bonding.

[0072] This embodiment, based on the specific magnet assembly 100 structure described above, provides a more specific implementation scheme for a precision micro-motor high-performance neodymium iron boron magnet assembly line, and provides a more detailed design for the structure and layout of each functional component. The structure and function of each part are described in detail below.

[0073] Regarding the magnet assembly 100: The magnet assembly 100 includes three mutually bonded materials (magnet 102, first yoke 101, and second yoke 103). It should be noted that, in addition to the yoke, other materials that need to be bonded can also be bonded to both sides of the magnet 102.

[0074] The operating principle and function of the multiplier chain circulation line 800 are as follows: The upper multiplier chain output line carries the transfer tray assembly 500 through each station and enters the tray lowering assembly 28. The tray lowering assembly 28 is used to lower the empty transfer tray assembly 500 to the lower multiplier chain return line 29, and then input it to the upper multiplier chain output line via the tray rising assembly 30, realizing the cyclic use of the transfer tray assembly 500. The upper multiplier chain output line is composed of three line segments spliced ​​together sequentially, with a certain gap between adjacent segments. Three sets of auxiliary passing components (first auxiliary passing component 46, second auxiliary passing component 47, and third auxiliary passing component 48) are used to assist the transfer tray assembly 500 in smoothly passing through three gaps (between the feeding and gluing section multiplier chain 25 and the baking and fixing section multiplier chain 26, between the baking and fixing section multiplier chain 26 and the magnetizing section multiplier chain 27, and between the magnetizing section multiplier chain 27 and the tray lowering assembly 28). The pusher cylinder assembly 031 includes a retractable pusher cylinder and a pusher plate driven by the pusher cylinder. In use, the pusher cylinder drives the pusher plate outwards, pushing the transfer tray assembly 500 located on the pusher plate across the gap and onto the loading point glue section multiplier chain 25. The auxiliary transmission component works in conjunction with the pusher cylinder assembly 031 to ensure that the transfer tray assembly 500 smoothly flows across the gap on the multiplier chain circulation line 800. The tray lifting assembly 30 also includes a tray lifting plate 301 and a screw lifting assembly 302 for driving the extension and retraction of the tray lifting plate 301. The screw lifting assembly 302 is a motor-driven screw transmission structure. In use, the transfer tray assembly 500 is located on the tray lifting plate 301 and moves up and down with the tray lifting plate 301.

[0075] The main reason why the upper multiplier chain output line is composed of three segments spliced ​​together is that the curing equipment 41 is an externally purchased component. Each end of the curing equipment 41 (along the production line direction) has an openable lifting door. After the lifting doors are lowered and closed, the curing equipment 41 has a closed heating space. Since the curing equipment 41 needs to form a closed heating space, the upper multiplier chain output line needs to be divided into at least one segment located within the curing equipment 41. Specifically, the baking fixed segment multiplier chain 26 is located within the curing equipment 41. The advantages of the upper multiplier chain output line being composed of three segments spliced ​​together are: using this structure, after adding a protective shell to the curing equipment 41, a baking module can be formed. The other two sections of the upper multiplier chain output line (the feeding and dispensing multiplier chain 25 and the magnetizing multiplier chain 27) are respectively set on the front working platform 44 and the rear working platform 45. The baking and curing processes are arranged on the front working platform 44 and the rear working platform 45 respectively. After adding a protective shell, an assembly module and a magnetizing unloading module can be formed. The assembly module, baking module and magnetizing unloading module are independent structures. They can be equipped with separate control structures (such as control panels), protective structures (alarm warning lights, protective shells) and housing structures (cabinets under the working platforms), forming a modular structure that facilitates separate design, processing, assembly and transfer. The lower multiplier chain return line 29 connects the assembly module, baking module and magnetizing unloading module, and is used for the smooth return of the empty openable transfer tray assembly 500.

[0076] Explanation of the layout scheme and advantages of functional components on the feeding side and dispensing side:

[0077] The feeding side is wider to match the larger volume of the first magnetic yoke feeding robot 036, the magnet feeding robot 037, and the second magnetic yoke feeding robot 038. The robots are installed in a relative or opposite manner, creating space for the vibratory feeder and maximizing space utilization. Since the feeding side is used for feeding, this structure, which centrally arranges the same functional components, creates a regular and clear boundary for the feeding function's coverage area. This facilitates functional area division, resulting in a rational and orderly structure that allows for the centralized and regular arrangement of power source pipes / lines.

[0078] On the dispensing side: The dispensing robot 039 is located on the dispensing side and has sufficient space to span two workstations, performing dispensing operations on the first magnetic yoke 101 and the magnet 102 respectively, saving costs. The pressing robot 40 includes an existing, readily available pressing three-axis linear robot module and a high-precision multi-head pressure pressing device mounted on the robot module. The specific structure of the high-precision multi-head pressure pressing device can be found in patent number 2023226550248. The extendable fork 13 is loaded onto the pressing robot 40, allowing the high-precision multi-head pressure pressing device and the extendable fork 13 to share a single power source, reducing equipment cost and size. The extendable fork 13 is an extendable structure, including a fork body with an opening. The top of the clamp 9 has a raised top step that protrudes to the side. The telescopic fork 13 is inserted below the top step and lifted up to lift the clamp 9 and the entire transfer tray assembly 500 across the gap and accurately place it on the baking fixed section multiple chain 26.

[0079] Regarding the arrangement and advantages of the functional components on the rear work platform 45: The unloading robot 43 and the magnetizer 42 are both located on the same side of the magnetization section multiplier chain 27, which is aligned with the loading side. This structure aligns the assembly module and the magnetizing unloading module in the width direction, which helps reduce the overall width of the precision micro-motor high-performance NdFeB magnet assembly line of this invention. In the automatic tray feeding and unloading device, the feeding unit 0100 and the unloading unit 0200 are arranged vertically. The direction of the feeding unit 0100 is generally opposite to the production line direction, while the direction of the unloading unit 0200 is consistent with the production line direction. The upper layer feeds empty trays, and the lower layer returns to full trays, forming a three-dimensional material conveying structure with upper and lower return flows, reducing the overall length of the automatic tray feeding and unloading device. With this structure, the empty material tray inlet 020 and the full material tray outlet 019 are located on the same side of the production line, allowing the automatic material tray feeding and discharging device to be directly connected to the upstream multi-chain circulation line 800. Furthermore, the empty material tray inlet 020 and the full material tray outlet 019 can be supervised by a single operator, reducing labor costs.

[0080] It should be noted that the first magnetic yoke loading robot 036, the magnet loading robot 037, and the second magnetic yoke loading robot 038 in this embodiment all include existing robot modules that can be directly purchased externally, enabling three-way movement along the XYZ axes. The dispensing robot is also an existing purchased component. In summary, by adopting the structure of this embodiment, the functional components are rationally designed and arranged, significantly reducing the overall volume, weight, and cost of the production line of this invention.

[0081] According to a specific embodiment of the present invention, the multiplier chain circulation line 800 and the tray opening and closing control assembly 600 are respectively installed on the production line frame 400. The openable and closable transfer tray assembly 500 further includes: a supporting base plate 8, a product positioning reference block 2 fixedly provided on the top of the supporting base plate 8, and a first opening and closing unit 3 and a second opening and closing unit 5 with symmetrical structures respectively provided on both sides of the product positioning reference block 2; multiple sets of tray opening and closing control assemblies 600 are provided below the upper multiplier chain output line, and the tray opening and closing control assembly 600 includes: a wedge block 14 and a wedge block telescopic linear drive 15 that provides telescopic power to the wedge block 14; the openable and closable transfer tray assembly 500 is located on the wedge block Under the squeezing action of 14, the openable flow transfer tray assembly 500 is opened and accumulates elastic force, thus putting the openable flow transfer tray assembly 500 in the open state; the openable flow transfer tray assembly 500 is in the closed state under the action of elastic force; when the openable flow transfer tray assembly 500 is in the closed state: the first opening and closing unit 3 and the second opening and closing unit 5 respectively form a product receiving groove with the product positioning reference block 2, the product receiving groove includes: a plurality of first product receiving grooves 4 that match the shape of the magnet assembly 100 and are jointly formed by the first opening and closing unit 3 and the product positioning reference block 2, and a plurality of second product receiving grooves 7 that match the shape of the magnet assembly 100 and are jointly formed by the second opening and closing unit 5 and the product positioning reference block 2.

[0082] In this embodiment, a tray opening and closing control component 600 is provided below each assembly station of the upper multiplier chain output line. The production line frame 400 is a frame structure used to provide a mounting and support foundation.

[0083] In the transfer tray assembly 500: the supporting base plate 8 is used for support, the product positioning reference block 2 is fixed to the supporting base plate 8, the first opening and closing unit 3 and the second opening and closing unit 5 respectively cooperate with the product positioning reference block 2 to form multiple openable and closable product receiving slots to receive the constituent materials of the magnet assembly 100. The slots can switch between closed and open states as required to realize and position the materials.

[0084] In the openable transfer tray assembly 500: under the action of the wedge block extension and retraction linear drive 15, the wedge block 14 simultaneously squeezes the first opening and closing unit 3 and the second opening and closing unit 5. The first opening and closing unit 3 and the second opening and closing unit 5 open simultaneously, facilitating the robot arm to insert and place materials into the magnet assembly 100 or to retrieve assembled materials. Furthermore, the transfer tray assembly 500 is equipped with elastic elements such as compression springs. When the first opening and closing unit 3 and the second opening and closing unit 5 open, they compress the compression springs. When the wedge block 14 moves in the opposite direction, under the elastic force of the compression springs, the first opening and closing unit 3 and the second opening and closing unit 5 retract, and the transfer tray assembly 500 is in a closed state.

[0085] In this embodiment: the transfer tray assembly 500 can automatically open and close to meet usage requirements, and the product receiving slots in the transfer tray assembly 500 are multiple in shape that match the magnet assembly 100. The transfer tray assembly 500 can accurately position multiple products simultaneously, and multiple magnet assemblies 100 can be assembled at the same time. The multiplier chain circulation line 800 can transfer the transfer tray assembly 500 to each workstation and realize the cyclical use of the transfer tray assembly 500.

[0086] According to a specific embodiment of the present invention, the first opening and closing unit 3 includes: a first product positioning block 31, a first connecting plate 32, a first mounting block 33, a first closing reset spring 34, and a first opening limiting post 35; the first product positioning block 31 is located on the side of the product positioning reference block 2, and the first product positioning block 31 and the product positioning reference block 2 together form a plurality of first product receiving slots 4; the first connecting plate 32 is located on the side of the first product positioning block 31 away from the product positioning reference block 2, and the first connecting plate 32 is slidably connected to the bearing base plate 8; the first mounting block 3 ... product positioning block 34 is slidably connected to the first product positioning base plate 8; the first product positioning block 35 is located on the side of the first product positioning block 31 away from the product positioning reference block 2, and the first product positioning block 35 is slidably connected to the first product positioning base plate 8; the first product positioning block 35 is located on the side of the first product positioning base plate 31 away from the product positioning reference block 2, and the first product positioning block 35 is slidably connected to the first product positioning base plate 34. A connecting plate 32 is located away from the product positioning reference block 2; the two ends of the first closing return spring 34 abut against the first mounting block 33 and the first connecting plate 32 respectively; one end of the first opening limit post 35 is fixed to the first mounting block 33, and the other end of the first opening limit post 35 faces the side of the first connecting plate 32; the second opening and closing unit 5 includes: a second product positioning block 51, a second connecting plate 52, a second mounting block 53, a second closing return spring 54, and a second opening limit post 55; the second product positioning block 51 is located on the side of the product positioning reference block 2, and the second product positioning... Block 51 and product positioning reference block 2 together form multiple second product receiving slots 7; the second connecting plate 52 is located on the side of the second product positioning block 51 away from the product positioning reference block 2, and the second connecting plate 52 is slidably connected to the bearing base plate 8; the second mounting block 53 is located on the side of the second connecting plate 52 away from the product positioning reference block 2; the two ends of the second closing return spring 54 abut against the second mounting block 53 and the second connecting plate 52 respectively; one end of the second opening limit post 55 is fixed to the second mounting block 53, and the other end of the second opening limit post 55 faces the side of the second connecting plate 52. The first opening and closing unit 3 also includes a first opening pusher 36; the first opening pusher 36 is mounted on the first connecting plate 32 or the first product positioning block 31; the second opening and closing unit 5 also includes a second opening pusher 56; the second opening pusher 56 is mounted on the second connecting plate 52 or the second product positioning block 51; the wedge block 14 simultaneously squeezes the first opening pusher 36 and the second opening pusher 56, and simultaneously pushes the first product positioning block 31 and the second product positioning block 51 to move in a direction away from the product positioning reference block 2, so that the openable and closable transfer tray assembly 500 is in the open state;

[0087] In this embodiment, the structure of the first opening and closing unit 3 and the second opening and closing unit 5 in the transfer disk assembly 500 is designed in more detail.

[0088] Regarding the open state of the transfer tray assembly 500: The telescopic linear drive drives the wedge block 14 to extend to the position between the first opening pusher 36 and the second opening pusher 56 (wedge block extension position 300), and then moves towards the product positioning reference block 2. The two wedge surfaces of the wedge block 14 simultaneously push the first opening pusher 36 and the second opening pusher 56, forcing the first product positioning block 31 and the second product positioning block 51 on both sides to slide simultaneously away from the product positioning reference block 2 until the first connecting plate 32 abuts against the first opening limit post 35 and the second connecting plate 52 abuts against the second opening limit post 55. At this time, the transfer tray assembly 500 is in the open state; while the first connecting plate 32 moves, it presses the first closed reset spring 34, and the first closed reset spring 34 accumulates elastic force; while the second connecting plate 52 moves, it presses the second closed reset spring 54, and the second closed reset spring 54 accumulates elastic force. In this state, all the first product receiving slots 4 and all the second product receiving slots 7 become larger, which is conducive to the robot arm putting materials into or taking materials out of the product receiving slots.

[0089] Regarding the closed state of the transfer tray assembly 500: The telescopic linear drive drives the wedge block 14 to retract away from the product positioning reference block 2. Under the action of the first closing return spring 34, it pushes the first product positioning block 31 and the first connecting plate 32 to slide towards the product positioning reference block 2 simultaneously. It stops when the first product positioning block 31 abuts against the product positioning reference block 2. At the same time, under the action of the second closing return spring 54, it pushes the second product positioning block 51 and the second connecting plate 52 to slide towards the product positioning reference block 2 simultaneously. It stops when the second product positioning block 51 abuts against the product positioning reference block 2. At this time, the transfer tray assembly 500 is in the closed state. In this state, all the first product receiving slots 4 and all the second product receiving slots 7 become smaller, and the materials constituting the magnet assembly 100 are securely contained in the product receiving slots. When the transfer tray assembly 500 moves with the production line or when the product is being glued, pressed, or cured, the transfer tray assembly 500 is in the closed state to ensure the product assembly production accuracy.

[0090] In this embodiment, the transfer tray assembly 500 employs a combination of a wedge block 14 and two opening pushers (first opening pusher 36 and second opening pusher 56) to synchronously open the first product positioning block 31 and the second product positioning block 51. This ensures the synchronicity of the movements of the first product positioning block 31 and the second product positioning block 51, reduces the number of power components, and lowers costs. More specifically, both the first opening pusher 36 and the second opening pusher 56 are capable of rotating around their own axes. This structure facilitates smooth opening.

[0091] According to a specific embodiment of the present invention, the first opening and closing unit 3 further includes a first closing limiting post 37, the two ends of which are a first fixed end 371 and a first abutting limiting end 372, the first fixed end 371 being fixed to the first connecting plate 32, and the first abutting limiting end 372 facing the side of the supporting base plate 8; the second opening and closing unit 5 further includes a second closing limiting post 57, the two ends of which are a second fixed end 571 and a second abutting limiting end 572, the second fixed end 5 ..., the second fixed end 571 being fixed to the first connecting plate 32, and the first abutting limiting end 372 facing the side of the supporting base plate 8, the second fixed end 571 being fixed to the first connecting plate 32, 71 is fixed to the second connecting plate 52, and the second abutting and limiting end 572 faces the side of the supporting base plate 8; when the openable and closable transfer tray assembly 500 is in the closed state: the first abutting and limiting end 372 abuts against the supporting base plate 8, there is a gap between the first product positioning block 31 and the product positioning reference block 2, and the second abutting and limiting end 572 abuts against the supporting base plate 8, there is a gap between the second product positioning block 51 and the product positioning reference block 2; the second closing limiting post 57 has the same structure as the first closing limiting post 37.

[0092] In this embodiment, both the first closing limiting post 37 and the second closing limiting post 57 are used for closing and limiting. During the closing process, when the first closing limiting post 37 abuts against the supporting base plate 8, there is a gap between the first product positioning block 31 and the product positioning reference block 2. That is, when closing, the first closing limiting post 37 hits the opposite component and limits it before the first product positioning block 31; the second closing limiting post 57 hits the opposite component and limits it before the second product positioning block 51. By adopting this structure, the product positioning blocks (first product positioning block 31 and second product positioning block 51) are prevented from directly colliding with the product positioning reference block 2 when closing, which reduces the impact on the position of the material in the product receiving cavity and helps to further improve the assembly accuracy. It should be noted that when assembling and producing the magnet assembly 100, the openable transfer tray assembly 500 needs to be opened to put in the lower layer of material, closed to achieve positioning of the material and dispensing glue, then opened again to stack the upper layer of material, and closed again to achieve positioning of the material. That is, the first product positioning block 31 and the second product positioning block 51 need to be opened and closed multiple times to repeatedly stack and assemble the material. The structure of this embodiment ensures positioning accuracy even with repeated opening and closing. In this embodiment, rotating the adjusting screw allows adjustment of its extension length, thereby adjusting the position of the closing limit and precisely adjusting the size of the first product receiving groove 4 when closed. The working principle of the second closing limit post 57 is the same as that of the first closing limit post 37, and will not be described again here.

[0093] According to a specific embodiment of the present invention, a set of first elastic pressing units 38 is provided on one side of each first product receiving slot 4. Each first product receiving slot 4 can accommodate one magnet assembly 100. The first elastic pressing unit 38 passes through the first product positioning block 31, and one end of the first elastic pressing unit 38 abuts against the first connecting plate 32. The other end of the first elastic pressing unit 38 extends into the first product receiving slot 4 and is used to abut against the side of the magnet assembly 100. A set of second elastic pressing units 58 is provided on one side of each second product receiving slot 7. Each second product receiving slot 7 can accommodate one magnet assembly 100. The second elastic pressing unit 58 passes through the second product positioning block 51, and one end of the second elastic pressing unit 58 abuts against the second connecting plate 52. The other end of the second elastic pressing unit 58 extends into the second product receiving slot 7 and is used to abut against the side of the magnet assembly 100. The first elastic pressing unit 38 and the second elastic pressing unit 58 have the same structure. In this embodiment, when the transfer tray assembly 500 is in the closed state, each first elastic pressing unit 38 abuts against the side of a magnet assembly 100, applying an elastic force to each magnet assembly 100 and pushing each magnet assembly 100 inward to ensure the accuracy of the position of each magnet assembly 100, achieving precise positioning of the magnet assembly 100, and ensuring high repeatability during repeated positioning. The working principle of the second elastic pressing unit 58 is the same as that of the first elastic pressing unit 38, and will not be described again here.

[0094] According to a specific embodiment of the present invention, the first elastic pressing unit 38 includes a first compression spring 381 and a first pressing post 382. A first pressing unit receiving hole is provided on the first product positioning block 31, which is composed of a first spring hole 311 and a first shaft hole 312. The diameter of the first spring hole 311 is larger than the diameter of the first shaft hole 312. The first pressing post 382 includes a first snap-fit ​​shaft section and a first telescopic shaft section fixedly connected. The first compression spring 381 and the first snap-fit ​​shaft section are both received within the first spring hole 311, and the first telescopic shaft section extends into the first spring hole 382. A shaft hole 312; the second elastic pressing unit 58 includes a second compression spring 581 and a second pressing column 582. The second product positioning block 51 is provided with a second pressing unit receiving hole that passes through it. The second pressing unit receiving hole is composed of a second spring hole 511 and a second shaft hole 512 that are connected. The diameter of the second spring hole 511 is larger than the diameter of the second shaft hole 512. The second pressing column 582 includes a second snap-fit ​​shaft section and a second telescopic shaft section that are fixedly connected. The second compression spring 581 and the second snap-fit ​​shaft section are both received in the second spring hole 511. The second telescopic shaft section extends into the second shaft hole 512.

[0095] This embodiment further defines the structure of the first elastic pressing unit 38 and the second elastic pressing unit 58. The structure and operating principle of the first elastic pressing unit 38 and the second elastic pressing unit 58 are the same, and the following description uses the first elastic pressing unit 38 as an example. When the first compression spring 381 is in a free state, the first telescopic shaft section extends a certain distance from the receiving hole of the first shaft hole 312. The first elastic pressing unit 38 moves closer to the product positioning reference block 2 along with the first product positioning block 31 and the first connecting plate 32. Until the transfer tray assembly 500 is in a closed state, the first telescopic shaft section abuts against the magnet assembly 100 and squeezes the first compression spring 381, ultimately realizing that the first pressing column 382 applies elastic force to each magnet assembly 100.

[0096] According to a specific embodiment of the present invention, the product positioning reference block 2 has multiple recessed product fixing grooves 21 on both sides; the first product positioning block 31 has a corresponding recessed first movable groove 313 on the side near the product fixing groove 21, and one product fixing groove 21 and one corresponding first movable groove 313 form a first product receiving groove 4; the first pressing unit receiving hole is connected to the first product receiving groove 4; the second product positioning block 51 has a corresponding recessed second movable groove 513 on the side near the product fixing groove 21, and one product fixing groove 21 and one corresponding second movable groove 513 form a second product receiving groove 7; the second pressing unit receiving hole is connected to the second product receiving groove 7; both the first product receiving groove 4 and the second product receiving groove 7 are rectangular in shape. In this embodiment, the shape of the product receiving groove (the first product receiving groove 4 or the second product receiving groove 7) matches the shape of the magnet assembly 100.

[0097] According to a specific embodiment of the present invention, the supporting base plate 8 includes a base plate body 81 that is generally flat. A raised reference block support platform 82 is provided on the upper part of the base plate body 81. The product positioning reference block 2 is fixedly installed on the reference block support platform 82 via connecting positioning components. The first opening / closing unit 3 and the second opening / closing unit 5 are both installed on the upper part of the base plate body 81, and are respectively installed on both sides of the reference block support platform 82. The first opening / closing unit 3 further includes a first sliding component 39 disposed between the base plate body 81 and the first connecting plate 32, used to achieve a sliding connection between the first connecting plate 32 and the supporting base plate 8. The second opening / closing unit 5 further includes a second sliding component 59 disposed between the base plate body 81 and the second connecting plate 52, used to achieve a sliding connection between the second connecting plate 52 and the supporting base plate 8. In this embodiment, the reference block support platform 82 is raised, which on the one hand, elevates the position of the product positioning reference block 2, facilitating the provision of installation space for the first sliding component 39 and the second sliding component 59.

[0098] The cross-section of the magnet assembly 100 is fan-shaped. Multiple magnet assemblies 100 are arranged into a ring and used as motor assembly accessories. The upper and lower surfaces of the magnet assembly 100 are arc surfaces. During assembly, it is inverted in the product receiving groove, and the projection of the magnet assembly 100 on the bottom surface of the receiving groove is rectangular.

[0099] According to a specific embodiment of the present invention, a support block 11 for limiting the extension length of the wedge block 14 is fixedly embedded on one side of the bottom of the reference block support platform 82, and a limiting block 12 is fixedly embedded on one side of the bottom of the reference block support platform 82; the base plate body 81 is generally rectangular, and the openable and closeable transfer tray assembly 500 also includes two wear-resistant strips 6 respectively provided on both sides of the lower part of the base plate body 81. The wear-resistant strips 6 are generally rectangular, and the four corners of the wear-resistant strips 6 are respectively provided with side chamfers 61, and the bottoms of both ends of the wear-resistant strips 6 in the length direction are respectively provided with bottom chamfers 62; the first opening push wheel 36 is installed on the lower part of the first connecting plate 32, and the second opening push wheel 56 is installed on the lower part of the second connecting plate 52.

[0100] In this embodiment, when the wedge block 14 extends to a preset length, it abuts against the opening limiting block 11. Using this structure, the extension length of the wedge block 14 can be adjusted by adjusting the installation position of the opening limiting block 11, thereby further adjusting the size of the receiving groove in the open state. The limiting block 12 is used to cooperate with the front-stop cylinder 20 on the production line to achieve limiting. Specifically, the limiting rod of the limiting cylinder extends and abuts against the limiting block 12, restricting the flow transfer tray assembly 500 from continuing to advance. Using the opening limiting block 11 and the limiting block 12 also prevents the bearing base plate 8 from being directly impacted. Furthermore, the opening limiting block 11 and the limiting block 12 can be made of impact-resistant or vibration-absorbing materials, and can be replaced individually after damage, greatly improving the overall performance of the flow transfer tray.

[0101] According to a specific embodiment of the present invention, the openable transfer tray assembly 500 further includes two wear-resistant strips 6 respectively disposed on both sides of the lower part of the base plate body 81. The wear-resistant strips 6 are generally rectangular, and the four corners of the wear-resistant strips 6 are respectively provided with side chamfers 61, and the bottom of both ends of the wear-resistant strips 6 in the length direction are respectively provided with bottom chamfers 62; two clamping covers 9 are respectively disposed at both ends of the upper part of the reference block support platform 82. In this embodiment, after adding the wear-resistant strips 6, the wear-resistant strips 6 replace the bearing base plate 8 in contact with the multiplier chain. In use, the wear-resistant strips 6 are in direct contact with the rollers on the multiplier chain. The wear-resistant strips 6 are made of plastic material, which can improve the contact friction between the wear-resistant strips 6 and the rollers, which is beneficial to the movement of the multiplier chain driving the transfer tray assembly 500. In addition, the use of wear-resistant strips 6 can avoid wear on the lower part of the bearing base plate 8. After long-term use and wear, the wear-resistant strips 6 can be directly replaced, which is convenient for maintenance. Because there is a certain gap between two adjacent multiple chain segments, the bottom chamfer 62 facilitates the smooth guidance of the transfer tray assembly 500 from one multiple chain to another, preventing the lower part of the wear-resistant strip 6 from getting stuck during transfer. Similarly, the side chamfer 61 facilitates the smooth guidance of the transfer tray assembly 500 from one multiple chain to another, preventing the side wall of the wear-resistant strip 6 from getting stuck during transfer. Two sleeve holes 821 are spaced apart, and each sleeve hole 821 contains a first positioning sleeve 10. The first sliding assembly 39 and the second sliding assembly 59 are identical; the first sliding assembly 39 includes a guide rail and a slider that cooperates with the guide rail.

[0102] According to a specific embodiment of the present invention, the pallet lifting and positioning assembly 700 includes: a positioning assembly support frame 16, a lifting cylinder 17, a lifting top plate 18, a lifting slide rail 19, a front deflector cylinder 20, a rear anti-reverse block 021, and positioning pins 22; the positioning assembly support frame 16 is generally rectangular, the lower part of the lifting cylinder 17 is mounted on the positioning assembly support frame 16, the lower part of the lifting cylinder 17 is connected to the lifting top plate 18 and is used to drive the lifting top plate 18 to rise and fall, there are two sets of lifting slide rails 19, and the two sets of lifting slide rails 19 are arranged along a set of diagonals of the positioning assembly support frame 16; the rear anti-reverse block 021 is installed on one side of the positioning assembly support frame 16, and the front deflector cylinder 20 is located on the other side of the positioning assembly support frame 16; the positioning pins 22 are respectively located on both sides of the lifting cylinder 17 and fixed to the upper part of the lifting top plate 18; the bottom of the reference block support platform 82 is provided with There is a recessed sleeve hole 821, and a first positioning sleeve 10 in an overall ring shape is provided in the sleeve hole 821. There are two first positioning sleeves 10, and the positions of the two first positioning sleeves 10 are aligned with the positions of the two positioning top pins 22. The bottom adjacent sides of the positioning component support frame 16 are connected to the production line frame 400 through adjustable screws 23. The wedge block telescopic linear drive 15 in a set of openable and closable transfer tray assembly 500 is installed on the positioning component support frame 16 in a set of tray lifting and positioning assembly 700. A stop post 1 is provided at each of the four corners of the upper part of the base plate body 81. The upper part of the stop post 1 is higher than the upper part of the product positioning reference block 2. The upper multiplier chain output line is also provided with a set of top pressing units above each assembly station. Each set of top pressing units includes four pressing frames 24, and the four pressing frames 24 are set directly above the four stop posts 1.

[0103] In this embodiment, the tray lifting and positioning assembly 700 is used to lift and fix the transfer tray assembly 500 located on the multi-chain circulation line 800 at the required work position to facilitate operations such as loading and dispensing. The positioning assembly support frame 16 provides an installation base for other components in the tray lifting and positioning assembly 700, as well as for the wedge block telescopic linear drive 15. Ultimately, one set of openable transfer tray assemblies 500 is installed on one set of tray lifting and positioning assemblies 700. The position of the positioning assembly support frame 16 can be adjusted by the adjustable screw 23 to ensure the accuracy of the positioning assembly support frame 16. Two sets of diagonally arranged lifting slide rails 19 provide stable guidance for the lifting of the lifting top plate 18. The rear backstop block 021 includes a block and a backstop compression spring. When the transfer tray assembly 500 moves along the production line direction, it presses down on the anti-reverse compression spring under the locking block, allowing the transfer tray assembly 500 to pass smoothly. After passing, the anti-reverse compression spring pushes up the locking block, restricting the transfer tray assembly 500 from moving in the opposite direction of the production line. In use, when the position sensor 014 senses that the transfer tray assembly 500 has moved to the preset work position, the front stop cylinder 20 rises up, blocking the front of the transfer tray assembly 500. The locking block in the rear anti-reverse locking block 021 locks the rear of the transfer tray assembly 500. In this state, the front and rear of the transfer tray assembly 500 are limited, and the transfer tray assembly 500 stops at the preset position of the upper multiplier chain output line, making it easy for the positioning top pin 22 to align with the insertion of the first positioning sleeve 10. To further secure the transfer tray assembly 500, the cylinder rod of the lifting cylinder 17 extends, driving the lifting top plate 18 and positioning pins 22 upwards. The two positioning pins 22 rise and insert into the two corresponding first positioning sleeves 10, lifting the transfer tray assembly 500 upwards and detaching it from the upper multiplier chain output line until the four stop posts 1 abut against the four pressure frames 24 above. In this state, the transfer tray assembly 500 is detached from the upper multiplier chain output line and is press-fitted and fixed from above and below, ensuring the stability of the product receiving slot position and facilitating precise positioning by the robotic arm for operations such as material loading and dispensing.

[0104] According to a specific embodiment of the present invention, the second auxiliary passage assembly 47 and the third auxiliary passage assembly 48 have the same structure. The second auxiliary passage assembly 47 includes: a material feeding telescopic cylinder 032, a mounting plate 033, and a reverse thrust block 034. The material feeding telescopic cylinder 032 is fixed to the mounting plate 033 and is used to drive the mounting plate 033 to extend and retract. The material feeding telescopic cylinder 032 is installed on one side of the production line frame 400. The reverse thrust block 034 is hinged to the mounting plate 033, and a mechanism for driving the reverse thrust block 034 to engage / disengage is also provided between the mounting plate 033 and the reverse thrust block 034. The coil spring 035 is open, and the mounting plate 033 is provided with a limiting surface 0331 for limiting the opening angle of the reverse thrust block 034; the front and rear sides of the reverse thrust block 034 are respectively the avoidance surface 0341 and the pushing surface 0342; the reverse thrust block 034 has a parallel production line state and a vertical production line state; when the reverse thrust block 034 is in the vertical production line state, the reverse thrust block 034 extends vertically into the upper multiplier chain output line; when the reverse thrust block 034 is in the parallel production line state, the reverse thrust block 034 exits from the upper multiplier chain output line.

[0105] In this embodiment, under the action of the coil spring 035, the reverse thrust block 034 extends above the upper multi-chain output line, and the reverse thrust block 034 is perpendicular to the production line direction (perpendicular to the production line state). When the transfer tray assembly 500 moves or the material feeding telescopic cylinder 032 actuates (extends or retracts) and the stop post 1 acts on the avoidance surface 0341, it pushes the reverse thrust block 034 to rotate to a state parallel to the production line (parallel to the production line state), without affecting the normal movement of the transfer tray assembly 500. When the avoidance surface 0341 disengages from the stop post 1, the reverse thrust block 034 is in its normal state under the action of the coil spring 035. When the material-feeding telescopic cylinder 032 is activated (extended or retracted) and the stop post 1 acts on the pushing surface 0342, the anti-reverse block 034 cannot rotate under the action of the limiting surface 0331. This transmits the extension or retraction force of the material-feeding telescopic cylinder 032 to the stop post 1, pushing the transfer tray assembly 500 to move, thus assisting the transfer tray assembly 500 in smoothly passing through the gap between the multiple chains. It should be noted that the installation direction of the material-feeding telescopic cylinder 032 determines whether it acts on the pushing surface 0342 in the extended or retracted state. With this embodiment, the anti-reverse block 034 has a reverse-stop function. The anti-reverse block 034 extending above the upper multiple chain output line will not affect the transfer tray assembly 500, and can smoothly push the transfer tray assembly 500 to move when needed. Furthermore, only one telescopic force (the material-feeding telescopic cylinder 032) is required to move the transfer tray assembly 500 across the gap, resulting in a simple, reliable, and low-cost structure.

[0106] As can be seen from the above, in addition to the function of cooperating with the pressure frame 24 to achieve upper and lower limit, the stop post 1 also has another function: when the transfer tray assembly 500 crosses two adjacent multiple chain segments, the reverse thrust block 034 acts on one side of the stop post 1. The stop post 1 is used to provide the force application point, and the reverse thrust block 034 pushes the transfer tray assembly 500 to move as a whole and flow into the next multiple chain segment.

[0107] Please refer to this carefully. Figure 19-24 According to a specific embodiment of the present invention, the feeding unit 0100 includes: a Z-axis lifting pallet 01 for lifting and lowering a material tray, an X-axis first telescopic support plate 02 and an X-axis second telescopic support plate 03 for jointly supporting opposite sides of the material tray; the X-axis first telescopic support plate 02 and the X-axis second telescopic support plate 03 are respectively located on the upper sides of the Z-axis lifting pallet 01; the space through which the Z-axis lifting pallet 01 lifts and lowers is a lifting channel, and a loading station 0036 is provided on one side of the lifting channel. 00 also includes a first upper Y-direction telescopic carrier plate 04 and a second upper Y-direction telescopic carrier plate 05 for extending into the lifting channel and transferring the material tray to the loading station 0036; the discharge unit 0200 includes a lifting assembly and a lower Y-direction telescopic carrier plate 040, the lower Y-direction telescopic carrier plate 040 is located below the first upper Y-direction telescopic carrier plate 04, the lifting assembly is used to carry the material tray down to the lower Y-direction telescopic carrier plate 040, and the lower Y-direction telescopic carrier plate 040 is used to carry the material tray to the empty material tray inlet 020.

[0108] The X, Y, and Z direction references in this embodiment Figure 21 The orientation of the XYZ coordinate system in the diagram; Figure 20 The direction of the middle arrow indicates the moving direction of the finished product tray 0400. The finished product tray 0400 is used to hold finished magnet components. An empty finished product tray 0400 is a tray without material, and a tray 0400 filled with material is a full tray. The feeding unit 0100 is used to feed empty trays, and the discharging unit 0200 is used to discharge full trays. The area above the Z-axis lifting pallet 01 is used to stack empty trays, and the empty tray inlet 020 is located above the full tray outlet 019. The feeding unit 0100 of this embodiment can realize the automatic separation and feeding of stacked finished product trays 0400. The feeding process is as follows.

[0109] Multiple empty material trays are loaded: The first telescopic support plate 02 and the second telescopic support plate 03 in the X direction both extend into the lifting channel. The empty material trays are stacked on the first telescopic support plate 02 and the second telescopic support plate 03 in the X direction, either manually or using hoisting equipment. The first telescopic support plate 02 and the second telescopic support plate 03 in the X direction support the two sides of the bottom empty material tray respectively.

[0110] Separate the bottom empty material tray: The Z-axis lifting pallet 01 rises and contacts the bottom empty material tray, continues to rise, lifts the bottom empty material tray and separates it from the X-axis first telescopic support plate 02 and X-axis second telescopic support plate 03, and transfers all empty material trays onto the Z-axis lifting pallet 01; the X-axis first telescopic support plate 02 and X-axis second telescopic support plate 03 retract to ensure unobstructed lifting channel. At this time, the Z-axis lifting pallet 01 can move freely up and down carrying the stacked empty material trays. The lower Y-axis telescopic plate 040 extends into the lifting channel, and the Z-axis lifting pallet 01 descends. After the bottom plate 0401 of the lowest empty material tray passes the first X-axis telescopic support plate 02 and the second X-axis telescopic support plate 03, the first X-axis telescopic support plate 02 and the second X-axis telescopic support plate 03 extend back into the lifting channel. The Z-axis lifting pallet 01 continues to descend, and the extended first X-axis telescopic support plate 02 and the second X-axis telescopic support plate 03 support the bottom plate 0401 of the second layer of empty material trays from bottom to top. At this time, the second layer and above empty material trays are all supported by the telescopic support plates (first X-axis telescopic support plate 02 and second X-axis telescopic support plate 03), while the lower empty material trays continue to descend with the Z-axis lifting pallet 01, thus separating the lower empty material trays from the upper finished material trays 0400.

[0111] Transferring the bottom empty tray to loading station 0036: During the period when the lifting channel is unobstructed, or before the Z-axis lifting pallet 01 descends to be flush with the upper surface of the lower Y-axis telescopic carrier plate 040, the lower Y-axis telescopic carrier plate 040 extends into the lifting channel, and the Z-axis lifting pallet 01 continues to descend, transferring the bottom empty tray to the lower Y-axis telescopic carrier plate 040. Then, the lower Y-axis telescopic carrier plate 040 carrying the bottom empty tray retracts and transfers the bottom empty tray to loading station 0036. At this time, the empty tray directly supported by the telescopic support plates (X-axis first telescopic support plate 02 and X-axis second telescopic support plate 03) becomes the new bottom empty tray.

[0112] Repeat the above steps to continuously feed empty material into the trays. Once all empty trays are used up, simply refill them.

[0113] The unloading process is as follows: The empty material tray is fed to the loading station 0036 and supported by the lifting component. After the loading robot or manual personnel stack the finished motor magnet components into the empty material tray in sequence, a full material tray is formed. The lifting component descends and transfers the full material tray to the lower Y-axis telescopic carrier plate 040. The lower Y-axis telescopic carrier plate 040 returns the material to the lower layer and transfers the full material tray to the full material tray outlet 019.

[0114] According to a specific embodiment of the present invention, the feeding unit 0100 further includes a lifting power component for driving the lifting pallet to rise and fall. The lifting power component is a two-stage lifting cylinder comprising an upper lifting cylinder 06 and a lower lifting cylinder 07 arranged vertically; and the stroke of the lower lifting cylinder 07 is greater than the stroke of the lower lifting cylinder 07. In this embodiment, by using a two-stage lifting cylinder as the power component, different strokes can be obtained to meet the usage requirements of different working conditions. When both the upper lifting cylinder 06 and the lower lifting cylinder 07 are extended, the longest stroke can be obtained, which can lift the perforated tray and separate it from the telescopic support plate (X-direction first telescopic support plate 02 and X-direction second telescopic support plate 03); when the Z-direction lifting pallet 01 descends, the lower lifting cylinder 07 or the upper lifting cylinder 06 can be lowered first, and then the other cylinder can be lowered. This can play a buffering role and prevent the second empty tray from hitting the telescopic support plate when the bottom empty tray is separated.

[0115] According to a specific embodiment of the present invention, the automatic feeding and discharging device for the material tray further includes a frame 0300, on which a secondary lifting cylinder is mounted; the feeding unit 0100 further includes a reciprocating belt drive assembly for synchronously extending and retracting the first upper Y-axis telescopic carrier plate 04 and the second upper Y-axis telescopic carrier plate 05. The reciprocating belt drive assembly includes: a feeding motor 08, a drive shaft 09 connected at one end to the feeding motor 08, and two sets of belt drive assemblies driven synchronously by the drive shaft 09; the belt drive assembly includes: a driving pulley 010, a driven pulley 011, and a toothed belt 012, with the driving pulley 010 fixed on the drive shaft 09; the first upper Y-axis telescopic carrier plate 04 is disposed on a set of belt drive assemblies. Below the drive assembly, the first upper Y-axis telescopic carrier plate 04 is fixedly connected to the toothed belt 012, and a Y-axis guide rail 013 is provided between the first upper Y-axis telescopic carrier plate 04 and the frame 0300; the second upper Y-axis telescopic carrier plate 05 is located below another set of belt drive assemblies, and the second upper Y-axis telescopic carrier plate 05 is fixedly connected to the toothed belt 012, and a Y-axis guide rail 013 is provided between the second upper Y-axis telescopic carrier plate 05 and the frame 0300; two position sensors 014 are provided on one side of one toothed belt 012, and the position sensors 014 are mounted on the frame 0300; the feeding motor 08, the drive shaft 09, and the driven pulley 011 are all respectively mounted on the frame 0300. More specifically, the first upper Y-axis telescopic carrier plate 04 and the second upper Y-axis telescopic carrier plate 05 are respectively mounted on the lower edge of the toothed belt 012 in the two sets of belt drive assemblies.

[0116] In this embodiment, the frame 0300 provides stable support. The frame 0300 is generally frame-shaped and can be an integral or modular structure, providing a fixed installation base. Its specific shape is determined according to the position and shape of the components and installation requirements. In use, the feeding motor 08 drives the transmission shaft 09 to rotate, which in turn drives the two drive pulleys 010 to rotate simultaneously, thereby driving the lower edge of the two toothed belts 012 to move synchronously. Changing the rotation direction of the feeding motor 08 changes the movement direction of the lower edge of the belt. Two limit sensors are used to detect the position of the lower edge of one toothed belt 012. Combined with the electrical control system, the forward and reverse rotation of the feeding motor 08 is controlled so that when the toothed belt 012 reaches its limit position, the feeding motor 08 reverses, and the toothed belt 012 moves in the opposite direction; ultimately, the first upper Y-axis telescopic carrier plate 04 and the second upper Y-axis telescopic carrier plate 05 are synchronously extended and retracted. The Y-axis guide rail 013 is used to achieve linear guidance between the frame 0300 and the telescopic support plate (first upper Y-axis telescopic carrier plate 04 or second upper Y-axis telescopic carrier plate 05), ensuring smooth and stable movement of the telescopic support plate. The drive shaft 09 enables long-distance synchronous transmission between the two sets of belt-driven components, ensuring that the first upper Y-axis telescopic carrier plate 04 and the second upper Y-axis telescopic carrier plate 05 are simultaneously inserted into the lifting channel from both sides of the Z-axis lifting tray 01 and receive the finished product tray 0400. This structure reduces power costs and is simple and reliable.

[0117] According to a specific embodiment of the present invention, the feeding unit 0100 further includes a first lateral driving part for driving the first telescopic support plate 02 in the X direction to extend and retract. The first lateral driving part includes: a lateral driving cylinder 015, a vertical connecting plate 016, and an X-direction guide rail 017. The lateral driving cylinder 015 is mounted on the frame 0300 via the X-direction guide rail 017. The vertical connecting plate 016 is connected to the lateral driving cylinder 015. The first telescopic support plate 02 in the X direction is fixedly installed on the lower part of the vertical connecting plate 016. The second telescopic support plate 03 in the X direction is symmetrical to the first telescopic support plate 02 in the X direction. The feeding unit 0100 further includes a second lateral driving part for driving the second telescopic support plate 03 in the X direction to extend and retract. The first lateral driving part and the second lateral driving part are symmetrical to each other.

[0118] In this embodiment, the first lateral drive unit and the second lateral drive unit are symmetrical structures. They operate on the same principle; the extension and retraction of the lateral drive cylinder 015 drives the extension and retraction of the vertical connecting plate 016 and the X-direction first telescopic support plate 02. In practice, the extension and retraction of the two lateral drive cylinders 015 can be controlled individually or simultaneously controlled via a synchronization valve.

[0119] According to a specific embodiment of the present invention, the automatic tray feeding and discharging device further includes an empty tray stacking bin 018. The empty tray stacking bin 018 includes two integral right-angle columns 0181 and two rotatable right-angle columns 0182 that together form a rectangular receiving space. The channel between the two rotatable right-angle columns 0182 is an empty tray inlet 020. The rotatable right-angle column 0182 includes a fixed plate 01821 and a rotating plate 01822 hinged to the fixed plate 01821. The empty tray stacking bin 018 also includes a limiting pin for restricting the rotating plate 01822 to the open state. The lower part of the integral right-angle column 0181 and the lower part of the fixed plate 01821 are respectively fixedly installed on the frame 0300, and the limiting pin is movably inserted into the frame 0300.

[0120] In this embodiment, the empty pallet stacking bin 018 is used to limit the position of the stacked empty pallets, ensuring the positional accuracy of the empty pallets and facilitating precise coordination between the empty pallets and other power components. Specifically, the single-sided gap between the bottom plate 0401 of the empty pallet and the upright (integral right-angle upright 0181 or flip-up right-angle upright 0182) is small, approximately 0.1mm. The fixed plate 01821 and the rotating plate 01822 are connected by a hinge with a coil spring 035. Under normal conditions, the included angle between the fixed plate 01821 and the rotating plate 01822 is 90°. After opening the rotating plate 01822 and limiting it with a limiting pin, the included angle between the fixed plate 01821 and the rotating plate 01822 is 180°. In this state, an empty pallet can be placed into the empty pallet inlet 020, realizing empty pallet loading.

[0121] According to a specific embodiment of the present invention, the lifting assembly includes: a lead screw 00021, a spiral slide 022, a material tray lifting support plate 023, a support plate rubber pad 024, a discharge motor 025, and a discharge belt drive assembly 026; the lead screw 00021 is vertically arranged, the material tray lifting support plate 023 is horizontally arranged, the support plate rubber pad 024 is installed on the upper part of the material tray lifting support plate 023, one side of the material tray lifting support plate 023 is fixedly connected to the spiral slide 022, and the spiral slide 022 is sleeved on the lead screw 00021. The screw 021 and the lead screw 00021 form a screw transmission mechanism. The screw slide 022 is also slidably connected to the frame 0300. The two ends of the lead screw 00021 are respectively installed on the frame 0300, and the lead screw 00021 is rotatably connected to the frame 0300. The discharge motor 025 is located on one side of the lead screw 00021, and the discharge belt transmission assembly 026 is located at the bottom of the discharge motor 025. The discharge belt transmission assembly 026 is connected to the bottom of the discharge motor 025 and the lead screw 00021 respectively.

[0122] In this embodiment, the discharge motor 025 is located on one side of the lead screw 00021 and driven by the discharge belt drive assembly 026, which reduces the height of the lifting assembly and solves the problem of not having a place to install the discharge motor 025 at the bottom. The pallet pad 024 is made of rubber material, which can prevent the bottom plate 0401 of the full material tray from directly contacting the material tray lifting pallet 023, thus playing a role in isolation and protection, and also has a buffering function. In use, after the finished product tray 0400 on the pallet pad 024 is full, the discharge motor 025 rotates, driving the spiral slide 022, the material tray lifting pallet 023 and the pallet pad 024 to descend as a whole, transferring the full material tray to the lower Y-axis telescopic carrier plate 040. Therefore, as can be seen from the above, the lifting assembly using this embodiment has a small vertical dimension and can buffer and prevent wear on the finished product tray 0400.

[0123] According to a specific embodiment of the present invention, the discharge unit 0200 further includes a full-pan receiving bin 027 and a lower Y-axis telescopic power assembly for driving the lower Y-axis telescopic carrier plate 040 to extend and retract; the lower Y-axis telescopic power assembly includes: a Y-axis telescopic cylinder 028, a lower Y-axis guide rail 029, and a lower Y-axis guide block 030; the lower Y-axis guide rail 029 is mounted on the frame 0300, one end of the Y-axis telescopic cylinder 028 is mounted on the frame 0300, and the other end of the Y-axis telescopic cylinder 028 is connected to the lower Y-axis telescopic carrier plate 040; the lower Y-axis guide block 030 is fixed to the lower part of the lower Y-axis telescopic carrier plate 040, and the lower Y-axis guide block 030... The lower Y-axis telescopic carrier plate 040 is slidably connected to the lower Y-axis guide rail 029. A drawer guide rail 0031 is provided on each side of the lower Y-axis telescopic carrier plate 040. The two ends of the full-tray receiving bin 027 are slidably connected to the two drawer guide rails 0031. An adsorption magnetic block 0032 is also provided between the drawer guide rails 0031 and the full-tray receiving bin 027. The full-tray receiving bin 027 has an inlet 0271 for the tray lifting pallet 023 to carry the tray into the bin. A drawout 0272 is provided on the side of the full-tray receiving bin 027 near the lifting assembly for the tray lifting pallet 023 to be pulled out. Baffles 0273 are provided on both sides of the drawout 0272 to block the tray. The lower Y-axis telescopic power assembly also includes a Y-axis buffer limiter 0033 for limiting the extension and retraction of the lower Y-axis telescopic carrier plate 040. A handle 0274 is provided on the side of the full-tray receiving bin 027 away from the full-tray receiving bin 027 and near the lifting assembly.

[0124] In this embodiment, the full-tray receiving bin 027 is used to receive full trays. The shape of the full-tray receiving bin 027 is adapted to the size of the base plate 0401 of the full tray. The width of the pull-out port 0272 is greater than the width of the tray lifting plate 023, ensuring that the tray lifting plate 023 can be pulled out from the pull-out port 0272. The baffle plate 0273 is used to block both sides of the base plate 0401 of the full tray when the tray lifting plate 023 is pulled out, ensuring that the full tray remains in the full-tray receiving bin 027. Under the action of the magnetic adsorption block 0032, the full-tray receiving bin 027 is adsorbed and fixed to the drawer guide rail 0031. Under the action of the Y-axis telescopic cylinder 028, the full-tray receiving bin 027 moves to directly below the tray lifting plate 023. The Y-axis buffer limiter 0033 is used to provide limit and buffer. The material tray lifting pallet 023 carries a full material tray down and enters the full material receiving bin 027 through the inlet 0271. The Y-axis telescopic cylinder 028 drives the lower Y-axis telescopic carrier plate 040, together with the full material receiving bin 027, to move towards the discharge port 019 of the full material tray, so that the full material tray is separated from the material tray lifting pallet 023. At the same time, the material tray lifting pallet 023 is pulled out from the extraction port 0272, realizing the transfer of a full material tray to the full material receiving bin 027. The material tray lifting plate 023 rises to pick up the next empty material tray. After filling it with finished materials of the magnet assembly, a full material tray is obtained. The aforementioned steps are repeated to stack the full material tray in the full material receiving bin 027. The height of the full material receiving bin 027 determines the number of stacking layers. When it is full, the operator located at the full material tray outlet 019 pulls the handle 0274. After the pulling force is greater than the magnetic attraction force of the magnetic block 0032, the drawer guide rail 0031 and the full material receiving bin 027 are separated. The full material receiving bin 027 slides along the drawer guide rail 0031 to the full material tray outlet 019. After the full material tray is taken out, the full material receiving bin 027 is pushed in for the next material receiving.

[0125] According to a specific embodiment of the present invention, the full-pan receiving hopper 027 is generally rectangular. A raised support column 0275 is provided at each of the four corners of the bottom of the full-pan receiving hopper 027. The top of the side wall of the full-pan receiving hopper 027 bends outward to form a guide notch. In this embodiment, a space is formed below the raised support column 0275 for the lowering of the tray lifting plate 023. When the first full-pan is placed into the full-pan receiving hopper 027, the raised support column 0275 supports the bottom of the full-pan, and the tray lifting plate 023 continues to move downward until the full-pan is completely detached from the tray lifting plate 023, which helps to ensure the placement accuracy of the full-pan. The guide notch is used to guide the full-pan when it enters, ensuring that the full-pan smoothly enters the full-pan receiving hopper 027. According to a specific embodiment of the present invention, the discharge unit 0200 further includes a lifting guide frame 0034, which forms a material tray guide channel 0035 with openings at the top and bottom. The side of the lower Y-axis telescopic power component away from the full material tray discharge port 019 is the receiving station 0037. The upper part of the lifting guide frame 0034 is directly opposite the loading station 0036, and the lower part of the lifting guide frame 0034 is directly opposite the receiving station 0037.

[0126] In this embodiment, when the material tray lifting pallet 023 carries the full material tray from the loading station 0036 to the receiving station 0037, it needs to pass through the lifting guide frame 0034. The lifting guide frame 0034 limits the side of the full material tray to ensure the positional accuracy of the full material tray and facilitates precise cooperation between the side of the full material tray and the power component below. In specific implementation, the single-sided gap between the full material tray and the side wall of the lifting guide frame 0034 is small, about 0.1mm, to ensure high positioning accuracy.

[0127] Please refer to this carefully. Figure 25-26According to a specific embodiment of the present invention, the finished product tray 0400 includes a tray support plate 001, on which n recessed magnetic strip receiving cavities 0011 are provided, where n is a natural number ≥ 1. Each magnetic strip receiving cavity 0011 contains a magnetic adsorption strip 003. The finished product tray 0400 also includes a partition unit fixed to the upper part of the tray support plate 001 and confining the magnetic adsorption strip 003 within the magnetic strip receiving cavity 0011. The partition unit includes multiple intermediate partitions 002 arranged vertically at intervals. One side of each intermediate partition 002 is provided with n first intermediate receiving slots 0021, and one side of each intermediate partition 002 is provided with slots corresponding to the n first intermediate receiving slots. Each card slot 0021 corresponds to one of n second middle card slots 0022; the first middle card slot 0021 in a middle partition 002 and the second middle card slot 0022 in an adjacent middle partition 002 form a middle product receiving cavity 007; a magnetic adsorption strip 003 is provided at the lower part of all middle product receiving cavities 007 located in the same column; the finished product tray 0400 also includes two second positioning sleeves 0010 respectively provided on both sides of the partition unit, the second positioning sleeves 0010 extend into the tray support plate 001 and are installed on the tray support plate 001, and the second positioning sleeves 0010 are provided with positioning holes that pass through them.

[0128] In this embodiment, the material tray 001 is arranged horizontally, and the magnetic strip receiving cavity 0011 is used to receive the magnetic adsorption strip 003, which is used to adsorb the finished magnetic component. The partition unit presses on the magnetic adsorption strip 003 to confine the magnetic adsorption strip 003 within the magnetic strip receiving cavity 0011. The middle product receiving cavity 007 is used to receive the finished magnetic component. Since the middle partition 002 is arranged vertically, a three-dimensional receiving cavity is formed, and multiple finished magnetic components can be stacked in each middle product receiving cavity 007. This greatly expands the capacity of the finished product tray 0400. After the cylinder positioning rod at the corresponding position on the production line extends, it is inserted into the positioning hole to position the material tray 001, ensuring the stability and accuracy of the finished product tray 0400, which facilitates the transfer of the finished magnetic component into the finished product tray 0400 by the unloading robot 43. The installation position of the second positioning sleeve 0010 can be adjusted according to actual needs, and the second positioning sleeve 0010 can also be replaced separately if damaged. In practice, the unloading robot 43, equipped with multiple rod-shaped suction heads, picks up finished magnet components from the finished product unloading end of the magnet component 100 production line. Each suction head picks up one finished magnet component and aligns with a central product receiving cavity 007. The suction head then probes into the magnetic strip receiving cavity 0011 from top to bottom, placing one finished magnet component into one corresponding product receiving cavity.

[0129] In summary, by using the finished product tray 0400, the unloading robot 43 can quickly and conveniently stack the finished magnetic components into the central product receiving cavity 007. Under the action of the magnetic adsorption strip 003, the finished magnetic components are firmly adsorbed, ensuring their regular and stable placement, facilitating subsequent retrieval and counting management, and preventing damage to the finished magnetic components from collisions.

Specifically: A pulse electromagnet is located beneath the hopper of the vibratory feeder, causing the hopper to vibrate vertically. An inclined spring plate drives the hopper to oscillate around its vertical axis. Parts inside the hopper rise along a spiral track due to this vibration. During this ascent, after a series of track selections or posture changes, the parts automatically enter the assembly or processing position in a uniform state according to assembly or processing requirements. Its purpose is to automatically and orderly orient and accurately transport disordered workpieces to the next process through vibration. The vision module is an existing purchased component, consisting of a camera, lens, light source, and adjustment structure, used for image positioning. The three-axis linear robot module includes XYZ axis linear modules. The four-axis robot can be an Epson SCARA robot. The seven steps of the assembly process of this invention are all independent actions. As shown in Table 1 (Decomposition Table of Timing Diagram for Precision Micro-Motor High-Performance NdFeB Magnet Assembly Line), step S3 (gluing of magnet 102 and assembly of the second yoke 103) is the most time-consuming, taking 32 / 10 = 3.2 seconds per piece, corresponding to a UPH of 1125 pcs / h. Additionally, the UPH of the baking and curing zone is 1050 pcs / h. Therefore, the UPH of this assembly line is 1050 pcs / h > 1000 pcs / h. Using this invention, the automatic assembly production of magnet components 100 can be achieved, and the resulting magnet components have a bonding accuracy of ±0.05mm and a bonding shear force greater than 100N. The product has high positional accuracy and a stable bond.
