Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly, and particularly relates to a magnetic tile conveying and surface mounting device for a motor. Background Art

[0002] The motor magnetic tile is a kind of permanent magnet, mainly a tile-shaped magnet used in permanent magnet motors. The types of magnetic tiles include different materials such as NdFeB and SmCo, each having different characteristics. They interact with the motor coil to generate a magnetic field to drive the motor to rotate. At the same time, the magnetic tile can also stabilize the speed of the motor so that it can still operate stably when the load changes.

[0003] There are various ways to mount magnetic tiles. Brushless motor rotors such as power tools and water pumps mostly adopt the embedded method, while model aircraft and electric vehicle motor rotors adopt the surface mounting method. The surface mounting method can be further divided into inner surface mounting and outer surface mounting (inner surface mounting is to annularly attach the magnetic tile to the inner side of the hollow rotor, and outer surface mounting is to annularly attach the magnetic tile to the outer side of the rotor, as Figure 1 shown is the outer surface mounting method).

[0004] In the existing outer surface mounting method of magnetic tiles, manual assembly is relied on by operators, that is, the operators sequentially annularly attach the glued magnetic tiles to the outer side wall of the rotor. This method is time-consuming and laborious. If there are few magnetic tiles, it is okay, but if there are many, the assembly efficiency is very low. Moreover, manual mounting cannot guarantee the accuracy of the magnetic tile mounting position, so it will lead to an increase in unqualified products and waste costs. Summary of the Utility Model

[0005] The utility model provides a magnetic tile conveying and surface mounting device for a motor, which solves the defects of low efficiency and inability to guarantee the qualified rate of finished products existing in the prior art relying on manual mounting.

[0006] To achieve the above object, the technical solution adopted by the utility model is: a magnetic tile conveying and surface mounting device for a motor, which includes:

[0007] A support assembly, the support assembly includes a support frame, side baffles fixedly spaced at the top of the support frame, a magnetic tile groove arranged between the side baffles, and a push plate movably arranged in the magnetic tile groove. The magnetic tile to be surface-mounted is placed in the magnetic tile groove;

[0008] A surface mounting assembly, the surface mounting assembly includes a moving plate movably arranged on one side of the support frame, a transition plate fixed on the top of the moving plate, a transition groove opened on one side of the transition plate, and a clamping jaw cylinder fixed on the side of the transition plate away from the transition groove. The magnetic tile in the magnetic tile groove falls into the transition groove and is held by the clamping jaw cylinder.

[0009] Optimally, it further includes a pressing-down component, which includes a lifting plate disposed above the side baffle in a liftable manner and a pressing strip fixed to the bottom of the lifting plate. The descending pressing strip presses the magnetic tiles in the magnetic tile groove into the transition groove.

[0010] Optimally, the support component further includes a support plate fixed to the top of the support frame, a main baffle fixed to one side of the support plate, an adaptation part integrally connected to the inner side of the main baffle, and a push groove and a through groove penetrating the support plate. The push plate penetrates the push groove and is placed in the magnetic tile groove, and the magnetic tiles in the magnetic tile groove fall into the transition groove through the through groove.

[0011] Optimally, the surface-mounting component further includes a guiding part obliquely arranged above the transition groove, a clamping plate fixed to the clamping jaw cylinder, and a blocking strip integrally connected to the opposite sides of the clamping plate. The magnetic tiles in the transition groove are held by the blocking strip.

[0012] Optimally, the support component further includes a vertical plate fixed to the inner side of the support frame, a sliding plate slidably connected to the top of the vertical plate, and a cushion block fixed to the inner side of the push plate. The push plate is fixed to the top of the sliding plate.

[0013] Optimally, the support component further includes a light channel opened on the side of the side baffle close to the main baffle, an infrared emitter fixed to one side of the side baffle, and an infrared receiver fixed to the other side of the side baffle. The infrared emitter cooperates with the infrared receiver.

[0014] Optimally, the support component further includes a driving wheel rotatably mounted on one side of the vertical plate, a conveyor belt wound around the driving wheel, and an upper clamping plate fixed to the conveyor belt. The sliding plate is fixed to the top of the upper clamping plate.

[0015] Optimally, the surface-mounting component further includes a surface-mounting slider fixed to one side of the support frame, a surface-mounting slide rail slidably mounted on the surface-mounting slider, and a moving cylinder fixed to the vertical plate and connected to the moving plate. The moving plate is fixed to the surface-mounting slide rail.

[0016] Due to the application of the above technical solutions, the utility model has the following advantages compared with the prior art:

[0017] The magnetic tile conveying and surface-mounting device for the motor of the utility model transfers single magnetic tiles to the surface-mounting component through the cooperation of the support component and the pressing-down component, and finally the surface-mounting component mounts the magnetic tiles on the outer peripheral surface of the rotor. The whole mounting process has a high degree of automation, improves the mounting efficiency of the magnetic tiles, saves costs, and can ensure the accuracy of the magnetic tile mounting position, thereby improving the qualified rate of the finished products.

[0032] The present utility model will be further described below with reference to the embodiments shown in the drawings.

[0033] As shown Figures 2 - 4 in the figure, it is a schematic structural diagram of a magnetic tile conveying and surface mounting device for a motor of the present utility model, which is usually used to convey a single magnetic tile and then mount the magnetic tile on the outer side surface of the rotor (as Figure 1 shown in the figure, the magnetic tiles are annularly attached to the outer side surface of the rotor). The device includes a support assembly 1, a pressing assembly 2 and a surface mounting assembly 3. The support assembly 1 is used to carry the magnetic tile group to be surface-mounted (the magnetic tile group is formed by overlapping multiple magnetic tiles in sequence); the pressing assembly 2 is used to press a single magnetic tile onto the surface mounting assembly 3, and finally the surface mounting assembly 3 mounts the magnetic tile on the outer side wall of the rotor.

[0034] The support assembly 1 is used to carry the magnetic tile group to be surface-mounted. The support assembly 1 includes a support frame 101, a support plate 102, a push groove 103, side baffles 104, a magnetic tile groove 105, a vertical plate 106, a driving wheel 107, a conveyor belt 108, an upper clamping plate 109, a lower clamping plate 110, a sliding plate 111, a support slide rail 112, a support slider 113, a push plate 114, a cushion block 115, a through groove 116, a main baffle 117, a light channel 118, an infrared emitter 119, an infrared receiver 120 and an adaptation part 121. The support frame 101 is welded by aluminum profiles and fixed on the motor assembly table by means of screw fastening. The support frame 101 mainly plays a role of support and fixation.

[0035] The support plate 102 is fixed on the top of the support frame 101 by means of screw fastening. The push groove 103 penetrates the support plate 102 in the vertical direction and is parallel to the length direction of the support plate 102 (when the push plate 114 moves in the push groove 103, the magnetic tile in the magnetic tile groove 105 is pushed forward).

[0036] There are two side baffles 104, which are vertically fixed on the top of the support plate 102 and are parallel to the length direction of the support plate 102. A magnetic tile groove 105 is formed between the two side baffles 104. The magnetic tiles to be surface-mounted are sequentially overlapped and placed in the magnetic tile groove 105. When the push plate 114 moves in the push groove 103, the magnetic tile in the magnetic tile groove 105 is pushed forward, and then a single magnetic tile is pushed onto the surface mounting assembly 3.

[0037] The main baffle 117 is fixed on one side of the two side baffles 104, and the adaptation part 121 is integrally connected to the inner side of the main baffle 117. The adaptation part 121 is arc-shaped and matches the shape of the magnetic tile. When the push plate 114 pushes the magnetic tile in the magnetic tile groove 105 forward, the magnetic tile is limited by the main baffle 117 and the adaptation part 121 to prevent the push plate 114 from pushing the magnetic tile excessively, thus affecting the transition blanking of the foremost magnetic tile.

[0038] As Figure 8As shown, the through slot 116 runs through the support plate 102 and is close to the main baffle 117. The shape of the through slot 116 matches the shape of the magnetic tile. When the push plate 114 pushes the magnetic tile in the magnetic tile groove 105 forward until the foremost magnetic tile abuts against the mating portion 121 of the main baffle 117, at this time the foremost magnetic tile is just above the through slot 116. Under the action of gravity, the foremost magnetic tile falls into the through slot 116 and then lands on the surface mount component 3 below. Due to the mutual adhesion of adjacent magnetic tiles, under the influence of friction, the foremost magnetic tile may adhere to the second magnetic tile adjacent to it and cannot fall normally. Therefore, the pressing component 2 presses down on the foremost magnetic tile to ensure the smooth dropping of the foremost magnetic tile.

[0039] The vertical plate 106 is vertically fixed between the support frames 101 by welding. There are two driving wheels 107 (i.e., the driving wheel and the driven wheel), which are respectively rotatably installed on the same side of the vertical plate 106 and are spaced apart. The conveyor belt 108 is wound around the two driving wheels 107. The servo motor is fixed on the other side of the vertical plate 106 and is connected to one of the driving wheels 107 for driving the driving wheel 107 to rotate, and then driving the conveyor belt 108 to rotate (in this embodiment, the conveyor belt 108 does not rotate 360°, but makes a reciprocating linear movement between the two driving wheels 107, that is, the upper conveyor belt makes a reciprocating linear movement between the two driving wheels 107, thereby driving the upper push plate 114 to move).

[0040] The support slide rail 112 is fixed to the top of the vertical plate 106 by means of screw fastening. The support slider 113 is slidably installed on the support slide rail 112. The slide plate 111 is fixed to the support slider 113. By providing the mutually cooperating support slide rail 112 and support slider 113, the stability of the reciprocating movement of the slide plate 111 is improved, and the inclination of the slide plate 111 is avoided, which may affect the pushing of the magnetic tile in the magnetic tile groove 105.

[0041] The upper clamping plate 109 is located at the top of the upper conveyor belt 108, and the lower clamping plate 110 is located at the bottom of the lower conveyor belt 108. The upper clamping plate 109 and the lower clamping plate 110 are fixed together, thereby clamping the upper conveyor belt 108. When the upper conveyor belt 108 moves, it will drive the upper clamping plate 109 and the lower clamping plate 110 to move synchronously and reciprocally.

[0042] The slide plate 111 is fixed to the upper clamping plate 109. The push plate 114 is fixed to the top of the slide plate 111 and passes through the push slot 103 and is placed in the magnetic tile groove 105. The conveyor belt 108 drives the push plate 114 to move in the push slot 103, thereby pushing the magnetic tile in the magnetic tile groove 105 forward.

[0043] The spacer block 115 is fixed to the inner side of the push plate 114, i.e., the side of the push plate 114 close to the magnetic tile. The material of the spacer block 115 is rubber, which plays a buffering role when pushing the magnetic tile forward to avoid leaving indentations on the magnetic tile.

[0044] As Figure 5 shown, the optical channel 118 is horizontally opened on the side of the side baffle 104 close to the main baffle 117. The infrared emitter 119 is fixed to the outer side of one of the side baffles 104, and the infrared receiver 120 is fixed to the outer side of the other side baffle 104. The infrared receiver 120 cooperates with the infrared emitter 119 to detect whether the position of the magnetic tile pushed in the magnetic tile groove 105 is accurate, ensuring that the magnetic tile can smoothly fall from the through groove 116.

[0045] The pressing-down assembly 2 is fixed to the top of the support frame 101 and is used to press a single magnetic tile down onto the surface-mounting assembly 3. The pressing-down assembly 2 includes a frame plate 201, an avoidance groove 202, a lifting slide table 203, a lifting plate 204, and a pressing strip 205. The frame plate 201 is fixed to the top of the support frame 101 and is erected above the side baffle 104. The avoidance groove 202 is opened at the bottom of the frame plate 201, and the avoidance groove 202 is used to avoid the magnetic tile in the lower magnetic tile groove 105.

[0046] The lifting slide table 203 is fixed to one side of the frame plate 201. The lifting plate 204 is connected to the lifting slide table 203, and the lifting slide table 203 drives the lifting plate 204 to move up and down. The pressing strip 205 is fixed to the bottom of the lifting plate 204, and the thickness of the pressing strip 205 is the same as the thickness of one magnetic tile, so as to push the foremost magnetic tile into the through groove 116 and then fall onto the lower surface-mounting assembly 3.

[0047] When the push plate 114 pushes the magnetic tile in the magnetic tile groove 105 forward until the foremost magnetic tile abuts against the mating portion 121 of the main baffle 117, at this time the foremost magnetic tile is just above the through groove 116, and the foremost magnetic tile falls into the through groove 116 under the action of gravity and then falls onto the lower surface-mounting assembly 3. Due to the mutual adhesion of adjacent two magnetic tiles, under the influence of friction, the foremost magnetic tile may adhere to the second magnetic tile adjacent to it and cannot fall normally. Therefore, the pressing-down assembly 2 presses down the foremost magnetic tile to ensure the smooth fall of the foremost magnetic tile. Therefore, the pressing-down assembly 2 only assists the fall of the foremost magnetic tile.

[0048] The surface mounting component 3 is arranged on one side of the support frame 101, and is used to receive the dropped frontmost magnetic tile and mount the magnetic tile on the outer surface of the rotor. The surface mounting component 3 includes a moving cylinder 301, a surface mounting slide rail 302, a surface mounting slider 303, a fixing plate 304, a jaw cylinder 305, a transition plate 306, a transition groove 307, a guiding portion 308, a clamping plate 309, a stop bar 310 and a moving plate 311. The moving cylinder 301 is fixed at the bottom of the vertical plate 106 and is used to push the moving plate 311 to move, so as to transfer the dropped magnetic tile.

[0049] The surface mounting slider 303 is fixed on one side of the support frame 101 through the fixing plate. The surface mounting slide rail 302 is slidably installed on the surface mounting slider 303. The moving plate 311 is fixed on the surface mounting slide rail 302 and is connected to the piston rod of the moving cylinder 301. When the moving cylinder 301 drives the moving plate 311 to move forward for mounting the magnetic tile, relying on the cooperation between the surface mounting slider 303 and the surface mounting slide rail 302, the stability of the movement of the moving plate 311 is ensured, thereby improving the effect of magnetic tile mounting.

[0050] The fixing plate 304 is fixed on the top of the moving plate 311, and the transition plate 306 is vertically fixed on the top of the fixing plate 304. As Figure 9 shown, the transition groove 307 is opened on one side of the transition plate 306 and is used to receive the magnetic tile dropped from the frontmost part of the magnetic tile groove 105. The guiding portion 308 is inclinedly arranged on the top of the transition groove 307. During the falling process of the magnetic tile, the guiding portion 308 is relied on to guide it to ensure that the magnetic tile smoothly falls into the transition groove 307.

[0051] As Figure 6 、 7 shown, the jaw cylinder 305 is fixed on the top of the fixing plate 304, and the clamping plate 309 is fixed on the jaw cylinder 305. The clamping plate 309 is driven by the jaw cylinder 305 to move inwards or outwards synchronously. The stop bar 310 is integrally connected to the opposite sides of the clamping plate 309. After the magnetic tile falls into the magnetic tile groove 105, the jaw cylinder 305 drives the clamping plate 309 to move inwards, so that the stop bar 310 moves inwards to hold the magnetic tile in the transition groove 307, preventing the magnetic tile from falling during the gluing and transfer processes.

[0052] After gluing the inner surface of the magnetic tile, the moving cylinder 301 drives the glued magnetic tile to move forward to be close to the rotor (the rotor is installed on the rotating table, and the rotating table drives the rotor to rotate, and then the magnetic tile is mounted on the outer peripheral surface of the rotor). The jaw cylinder 305 is opened, and the moving cylinder 301 continues to push forward, so as to stick the glued magnetic tile on the outer peripheral surface of the rotor.

[0053] The magnetic tile conveying and surface mounting device for the motor of the utility model transfers a single magnetic tile to the surface mounting component 3 through the cooperation of the supporting component 1 and the pressing-down component 2. Finally, the surface mounting component 3 mounts the magnetic tile on the outer peripheral surface of the rotor. The whole mounting process has a high degree of automation, improves the mounting efficiency of the magnetic tile, saves more costs, and can ensure the mounting position accuracy of the magnetic tile, thus improving the qualified rate of the finished product.

[0054] The above embodiments are only used to illustrate the technical concept and characteristics of the utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the utility model and implement it accordingly. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit and essence of the utility model should be covered within the protection scope of the utility model.
