Description

Technical Field

[0001] The utility model belongs to the technical field of motor magnet assembly production, and in particular relates to an automatic material tray feeding and discharging device used for a motor magnet assembly production line. Background Art

[0002] Magnet assemblies are used in precision micro motors. Magnet assemblies include magnet bodies and yoke sheets bonded to the magnet bodies. The motor magnet assembly production line is used to realize the automatic assembly of motor magnets. When the motor magnets are assembled and produced, the finished motor magnets need to be loaded on a tray. In order to improve the degree of automation, a corresponding tray automatic feeding and unloading device needs to be designed.

[0003] The structure of the conventional automatic tray feeding and unloading device in the prior art is as follows: the two ends of the automatic feeding and unloading device are the feeding end and the discharging end respectively. The feeding end is used for feeding empty trays, and the discharging end is used for discharging full trays. With this structure, when the feeding end is docked with the front magnet assembly production line, a feeding station needs to be set on one side of the feeding end to facilitate the loading of empty trays.

[0004] The shortcomings of the existing technology are: on the one hand, the structure of the feed and discharge ends are located on both sides of the separation, and the overall length of the automatic feed and discharge device is relatively long, which is not suitable for scenarios with restrictions on the length of the production line. On the other hand, the feed end and the discharge end are far apart, and a workstation needs to be set up separately. If an operator is set up at each workstation, the labor cost increases. If only one operator is set up, the operator needs to run between the two ends, which increases the labor intensity and has poor results.

[0005] Therefore, it is necessary to provide a new automatic feeding and unloading device for a material tray used in a motor magnet assembly production line to solve the above technical problems. Utility Model Content

However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0044] The following is combined with Figure 1-14The automatic feeding and unloading device for the material tray of the motor magnet assembly production line of the utility model is further described. Figure 2 The direction of the arrow in the middle is the moving direction of the material tray 400; the X, Y, and Z directions in this utility model refer to Figure 4 The direction of the XYZ coordinate system in; Figure 9-14 The following are the action processes of the feeding unit 100, wherein the direction of the arrow is the direction of the component action.

[0045] The utility model discloses an automatic feeding and discharging device for a material tray used in a motor magnet assembly production line. The material tray 400 is used to hold assembled materials (finished magnet products). A material tray 400 without materials is an empty material tray, and a material tray 400 filled with materials is a full material tray. The automatic feeding and discharging device for a material tray used in a motor magnet assembly production line comprises a feeding unit 100 for feeding empty material trays and a discharging unit 200 for discharging full material trays; the feeding unit 100 comprises: a Z-direction lifting tray 1 for lifting and lowering the material tray 400, a first X-direction telescopic support plate 2 and a second X-direction telescopic support plate 3 for jointly supporting opposite sides of the material tray 400; the first X-direction telescopic support plate 2 and the second X-direction telescopic support plate 3 are respectively located on both sides of the upper part of the Z-direction lifting tray 1; the space through which the Z-direction lifting tray 1 is lifted and lowered is a lifting channel 35, and a loading station 36 is provided on one side of the lifting channel 35, and a feeding station 36 is provided on one side of the lifting channel 35. The unit 100 also includes a first upper Y-axis telescopic carrier plate 4 and a second upper Y-axis telescopic carrier plate 5 for extending into the lifting channel 35 and transferring the material tray 400 to the loading station 36; the unloading unit 200 includes a lifting component and a lower Y-axis telescopic carrier plate 40, the lower Y-axis telescopic carrier plate 40 is arranged below the first upper Y-axis telescopic carrier plate 4, the lifting component is used to carry the material tray 400 down to the lower Y-axis telescopic carrier plate 40, and the upper and lower sides of the Z-axis lifting tray 1 away from the loading station 36 are the feed port 20 and the discharge port 19 respectively; the lower Y-axis telescopic carrier plate 40 is used to carry the material tray 400 to the feed port 20.

[0046] More specifically, the bottom plate 401 of the empty material tray is rectangular, the first X-direction telescopic support plate 2 and the second X-direction telescopic support plate 3 are used to support a group of opposite sides of the bottom plate 401 of the empty material tray, and the first upper Y-direction telescopic carrier plate 4 and the second upper Y-direction telescopic carrier plate 5 are used to support another group of opposite sides of the bottom plate 401 of the empty material tray.

[0047] The upper part of the Z-direction lifting tray 1 is used for stacking empty trays, and the feeding port 20 of the empty trays is located above the discharging port 19. The feeding unit 100 of this embodiment can realize automatic separation and feeding of the stacked trays 400, and the feeding process is as follows.

[0048] Load multiple empty trays: Both the first telescopic support plate 2 in the X direction and the second telescopic support plate 3 in the X direction are extended into the lifting channel 35. The empty trays are stacked on the first telescopic support plate 2 in the X direction and the second telescopic support plate 3 in the X direction manually or by using lifting equipment. The first telescopic support plate 2 in the X direction and the second telescopic support plate 3 in the X direction support the two sides of the bottom empty tray respectively. Considering the load-bearing range of the first telescopic support plate 2 in the X direction and the second telescopic support plate 3 in the X direction, 2-5 empty trays are stacked at a time. Fig. 9 , showing the state of stacking three perforated trays 400.

[0049] Separate the bottom empty trays: The Z-axis lifting tray 1 rises and contacts the bottom empty trays, continues to rise, lifts the bottom empty trays and separates them from the X-axis first telescopic support plate 2 and the X-axis second telescopic support plate 3, and transfers all the empty trays to the Z-axis lifting tray 1 (such as Fig.10 ); The first telescopic support plate 2 in the X direction and the second telescopic support plate 3 in the X direction are retracted to ensure that the lifting channel 35 is unobstructed. At this time, the Z-direction lifting tray 1 can carry the stacked empty trays and move freely up and down (such as Fig.11 The lower Y-direction telescopic carrier plate 40 extends into the lifting channel 35, and the Z-direction lifting tray 1 descends until the bottom plate 401 of the empty tray at the bottom layer passes through the first X-direction telescopic support plate 2 and the second X-direction telescopic support plate 3. The first X-direction telescopic support plate 2 and the second X-direction telescopic support plate 3 extend into the lifting channel 35 again, and the Z-direction lifting tray 1 continues to descend. The extended first X-direction telescopic support plate 2 and the second X-direction telescopic support plate 3 will support the bottom plate 401 of the second layer of empty trays from the bottom to the top. At this time, the empty trays on the second layer and above are supported by the telescopic support plates (the first X-direction telescopic support plate 2 and the second X-direction telescopic support plate 3), and the empty trays on the lower layer still move downward with the Z-direction lifting tray 1, so as to realize the separation of the empty trays on the lower layer from the upper tray 400 (such as Fig.12 ).

[0050] Transfer the bottom empty tray to the loading station 36: During the period when the lifting channel 35 is unobstructed, or before the Z-axis lifting tray 1 moves downward to be flush with the upper surface of the lower Y-axis telescopic carrier 40, the lower Y-axis telescopic carrier 40 extends into the lifting channel 35, and the Z-axis lifting tray 1 continues to descend, and the bottom empty tray is transferred to the lower Y-axis telescopic carrier 40 (such as Fig.13 ), and then the lower Y-axis telescopic carrier plate 40 is retracted with the bottom empty tray, and the bottom empty tray is transferred to the loading station 36. At this time, the empty tray directly supported by the telescopic support plate (the first telescopic support plate 2 in the X direction and the second telescopic support plate 3 in the X direction) becomes the new bottom empty tray (such as Fig.14 ).

[0051] Repeat the above operation to realize continuous loading of empty trays. When all empty trays are used up, continue to load empty trays.

[0052] The unloading process is as follows: an empty tray is fed to the loading station 36 and supported by the lifting assembly. After the loading robot or manual operation has sequentially stacked the motor magnet products into the empty tray, a full tray is formed. The lifting assembly descends and transfers the full tray to the lower Y-axis telescopic carrier plate 40. The lower Y-axis telescopic carrier plate 40 refluxes at the lower layer and transfers the full tray to the discharge port 19.

[0053] The automatic feeding and unloading device for the material tray used in the motor magnet assembly production line of the utility model has the following beneficial effects:

[0054] With the utility model, the upper layer feeds the empty tray, and the lower layer refluxes into the full tray, forming a three-dimensional feeding structure with upper and lower layers of reflux, reducing the overall length of the device. In addition, in the utility model, the (empty tray) feed port 20 and the (full tray) discharge port 19 are located on the same side of the production line, which is conducive to the connection with the upstream motor magnet assembly section on the one hand, and the utility model can be directly used as an extension line of the upstream motor magnet assembly section. On the other hand, the feed port 20 and the discharge port 19 are located on the same side, and can share one operator to reduce labor costs.

[0055] According to a specific embodiment of the present utility model, the feeding unit 100 also includes a lifting power component for driving the lifting tray to lift and lower, and the lifting power is a two-stage lifting cylinder including an upper lifting cylinder 6 and a lower lifting cylinder 7 arranged up and down; and the stroke of the lower lifting cylinder 7 is greater than the stroke of the upper lifting cylinder 7.

[0056] In this embodiment, by using the two-stage lifting cylinder as the power part, three different strokes can be obtained to meet the use requirements of different working conditions. When the upper lifting cylinder 6 and the lower lifting cylinder 7 are both extended, the longest stroke can be obtained, and the hole carrier can be lifted and separated from the telescopic support plate (the first telescopic support plate 2 in the X direction and the second telescopic support plate 3 in the X direction); when the Z-axis lifting tray 1 is lowered, the lower lifting cylinder 7 or the upper lifting cylinder 6 can be lowered first, and then the other cylinder can be lowered, which can play a buffering role and prevent the second layer of empty trays from hitting the telescopic support plate when the bottom layer of empty trays is separated.

[0057] It should be noted that the lifting power part can also be a first-stage cylinder, but it must have a braking function and a stroke sensing element must be set at a preset stroke position.

[0058] According to a specific embodiment of the utility model, the automatic feeding and unloading device for the material tray of the motor magnet assembly production line also includes a frame 300, and the secondary lifting cylinder is installed on the frame 300; the feeding unit 100 also includes a reciprocating belt transmission assembly for driving the first upper Y-direction telescopic carrier 4 and the second upper Y-direction telescopic carrier 5 to synchronously extend and retract, and the reciprocating belt transmission assembly includes: a feeding motor 8, a transmission shaft 9 connected to the feeding motor 8 at one end, and two sets of belt transmission components driven by the transmission shaft 9 to rotate synchronously; the belt transmission component includes: a driving pulley 10, a fixed pulley 11 and a toothed belt 12, and the driving pulley 10 is fixed on the transmission shaft 9; the first upper Y-direction telescopic carrier 4 It is arranged below a set of belt transmission components, and the first upper Y-direction telescopic carrier plate 4 is fixedly connected to the toothed belt 12, and a Y-direction guide rail 13 is arranged between the first upper Y-direction telescopic carrier plate 4 and the frame 300; the second upper Y-direction telescopic carrier plate 5 is arranged below another set of belt transmission components, and the second upper Y-direction telescopic carrier plate 5 is fixedly connected to the toothed belt 12 through a clamping block 41, and a Y-direction guide rail 13 is arranged between the second upper Y-direction telescopic carrier plate 5 and the frame 300, and two position sensors 14 are arranged on one side of a toothed belt 12, and the position sensor 14 is installed on the frame 300; the feeding motor 8, the transmission shaft 9, and the fixed pulley 11 are respectively installed on the frame 300.

[0059] More specifically, the first upper Y-direction telescopic carrier plate 4 and the second upper Y-direction telescopic carrier plate 5 are respectively installed on the lower side belts of the toothed belts 12 in the two sets of belt transmission components.

[0060] In the present invention, the rack 300 is used to provide a stable support. The rack 300 is in the shape of a frame as a whole, and can be an integral structure or a split structure, and is used to provide a fixed installation foundation, and its specific shape is determined according to the position and shape installation requirements of the components.

[0061] When in use, the feeding motor 8 drives the transmission shaft 9 to rotate, driving the two active pulleys 10 to rotate simultaneously, thereby driving the lower side belts of the two toothed belts 12 to move synchronously. Changing the rotation direction of the feeding motor 8 can change the movement direction of the lower side belt accordingly. Two limit sensors are used to detect the position of the lower side belt of a toothed belt 12. Combined with the control system, the forward and reverse rotation of the feeding motor 8 is controlled, so that after the toothed belt 12 reaches the limit position, the feeding motor 8 is reversed, and the toothed belt 12 moves in the opposite direction; finally, the first upper Y-direction telescopic carrier 4 and the second upper Y-direction telescopic carrier 5 are synchronously telescoped. The Y-direction guide rail 13 is used to realize the linear guidance of the frame 300 and the telescopic support plate (the first upper Y-direction telescopic carrier 4 or the second upper Y-direction telescopic carrier 5) to ensure the smoothness and stability of the movement of the telescopic support plate.

[0062] In this embodiment, the transmission shaft 9 can realize long-distance synchronous transmission of two sets of belt transmission components, which can ensure that the first upper Y-direction telescopic carrier plate 4 and the second upper Y-direction telescopic carrier plate 5 are inserted into the lifting channel 35 from both sides of the Z-direction lifting tray 1 and receive the hole material tray 400. The use of this structure reduces power costs and has a simple and reliable structure.

[0063] According to a specific embodiment of the present utility model, the feeding unit 100 also includes a first lateral driving part for driving the first telescopic support plate 2 in the X direction to extend and retract, and the first lateral driving part includes: a lateral driving cylinder 15, a vertical connecting plate 16 and an X-direction guide rail 17; the lateral driving cylinder 15 is installed on the frame 300 via the X-direction guide rail 17, the vertical connecting plate 16 is connected to the lateral driving cylinder 15, and the first telescopic support plate 2 in the X direction is fixedly installed on the lower part of the vertical connecting plate 16; the second telescopic support plate 3 in the X direction and the first telescopic support plate 2 in the X direction are symmetrical structures to each other; the feeding unit 100 also includes a second lateral driving part for driving the second telescopic support plate 3 in the X direction to extend and retract, and the first lateral driving part and the second lateral driving part are symmetrical structures to each other.

[0064] In this embodiment, the first lateral drive unit and the second lateral drive unit are symmetrical structures. Their operating principles are the same. The extension and retraction of the lateral drive cylinder 15 can drive the vertical connecting plate 16 and the first telescopic support plate 2 in the X direction to extend and retract. In specific implementation, the extension and retraction of the two lateral drive cylinders 15 can be controlled separately or simultaneously through a synchronous valve to control the extension and retraction of the two lateral drive cylinders 15.

[0065] According to a specific embodiment of the utility model, the automatic material tray loading and unloading device for the motor magnet assembly production line also includes an empty tray stacking bin 18, the empty tray stacking bin 18 includes two integral right-angle columns 181 and two flippable right-angle columns 182 that together form a rectangular accommodating space, the channel between the two flippable right-angle columns 182 is a feed port 20, the flippable right-angle column 182 includes a fixed plate 1821 and a rotating plate 1822 hinged to the fixed plate 1821, the empty tray stacking bin 18 also includes a limit pin (not shown) for limiting the rotating plate 1822 to an open state, the lower part of the integral right-angle column 181 and the lower part of the fixed plate 1821 are respectively fixedly mounted on the frame 300, and the limit pin is movably plugged into the frame 300.

[0066] In this embodiment, the empty tray stacking bin 18 is used to limit the position of the stacked empty trays, ensure the position accuracy of the empty trays, and facilitate accurate coordination with other power parts. In specific implementation, the single-sided gap between the bottom plate 401 of the empty tray and the column (the integral right-angle column 181 or the flippable right-angle column 182) is small, about 0.1 mm.

[0067] The fixed plate 1821 and the rotating plate 1822 are connected by a hinge with a coil spring. Under normal circumstances, the angle between the fixed plate 1821 and the rotating plate 1822 is 90°. After the rotating plate 1822 is opened and limited by a limit pin, the angle between the fixed plate 1821 and the rotating plate 1822 is 180°. In this state, an empty tray can be put in from the feed port 20 to realize the loading of the empty tray.

[0068] According to a specific implementation of the utility model, the lifting assembly includes: a screw rod 21, a spiral slide 22, a lifting pallet 23, a pallet rubber pad 24, a discharge motor 25 and a discharge belt transmission assembly 26; the screw rod 21 is vertically arranged, the lifting pallet 23 is horizontally arranged, the pallet rubber pad 24 is installed on the upper part of the lifting pallet 23, one side of the lifting pallet 23 is fixedly connected to the spiral slide 22, the spiral slide 22 is sleeved on the screw rod 21 and forms a spiral transmission mechanism with the screw rod 21, the spiral slide 22 is also slidably connected to the frame 300, the two ends of the screw rod 21 are respectively installed on the frame 300, and the screw rod 21 is rotationally connected to the frame 300, the discharge motor 25 is located on one side of the screw rod 21, the discharge belt transmission assembly 26 is located at the bottom of the discharge motor 25, and the discharge belt transmission assembly 26 is respectively connected to the discharge motor 25 and the bottom of the screw rod 21.

[0069] More specifically, the discharge motor 25 is a servo motor.

[0070] In this embodiment, the discharge motor 25 is arranged on one side of the screw rod 21 and is driven by the discharge belt transmission assembly 26, which can reduce the height of the lifting assembly and solve the problem of having no place to place the discharge motor 25 at the bottom.

[0071] The support plate rubber pad 24 is made of rubber material, which can prevent the full tray bottom plate 401 from directly contacting the lifting support plate 23, plays a role of isolation and protection, and also has a certain buffering function.

[0072] During use, after the material tray 400 on the pallet rubber pad 24 is full, the discharge motor 25 rotates, driving the spiral slide 22, the lifting pallet 23 and the pallet rubber pad 24 to descend as a whole, and transferring the full material tray to the lower Y-direction telescopic carrier 40.

[0073] Therefore, it can be seen from the above that the lifting assembly of this embodiment has a small vertical dimension and can provide a buffering and anti-wear effect on the material tray 400.

[0074] According to a specific embodiment of the present invention, the discharging unit 200 also includes a full tray receiving bin 27 and a lower Y-direction telescopic power assembly for driving the lower Y-direction telescopic carrier 40 to telescope; the lower Y-direction telescopic power assembly includes: a Y-direction telescopic cylinder 28, a lower Y-direction guide rail 29 and a lower Y-direction guide block 30; the lower Y-direction guide rail 29 is mounted on a frame 300, one end of the Y-direction telescopic cylinder 28 is mounted on the frame 300, the other end of the Y-direction telescopic cylinder 28 is connected to the lower Y-direction telescopic carrier 40, the lower Y-direction guide block 30 is fixed to the lower part of the lower Y-direction telescopic carrier 40, and the lower The Y guide block 30 is slidably connected to the lower Y guide rail 29, and a drawer guide rail 31 is respectively provided on both sides of the lower Y-direction telescopic carrier plate 40, and the two ends of the full tray receiving bin 27 are respectively slidably connected to the two drawer guide rails 31; an adsorption magnet 32 ​​is also provided between the drawer guide rail 31 and the full tray receiving bin 27; the full tray receiving bin 27 is provided with an entrance 271 for the lifting and lowering pallet 23 carrying the full tray to enter, and the full tray receiving bin 27 is provided with an extraction port 272 for extracting the lifting and lowering pallet 23 on one side close to the lifting component, and blocking plates 273 for blocking the two sides of the full tray are respectively provided on both sides of the extraction port 272.

[0075] According to the specific implementation of the utility model, the lower Y-direction telescopic power assembly also includes a Y-direction buffer limiter 33 for limiting the telescopic position of the lower Y-direction telescopic carrier plate 40; a handle 274 is provided on the side of the full tray receiving bin 27 away from the full tray receiving bin 27 and close to the lifting assembly.

[0076] In this embodiment, the full tray receiving bin 27 is used to receive the full tray. The shape of the full tray receiving bin 27 is adapted to the size of the bottom plate 401 of the full tray, the width of the extraction port 272 is greater than the width of the lifting support plate 23, so as to ensure that the lifting support plate 23 can be extracted from the extraction port 272, and the material blocking plate 273 is used to block the two sides of the bottom plate 401 of the full tray when the lifting support plate 23 is extracted, so as to ensure that the full tray remains in the full tray receiving bin 27.

[0077] Under the action of the adsorption magnet 32, the full tray receiving bin 27 is adsorbed and fixed to the drawer guide rail 31. Under the action of the Y-direction telescopic cylinder 28, the full tray receiving bin 27 moves to the right below the lifting support plate 23. The Y-direction buffer limiter 33 is used to provide limit and buffer. The lifting support plate 23 carrying a full tray descends and enters the full tray receiving bin 27 through the inlet 271. The Y-direction telescopic cylinder 28 drives the lower Y-direction telescopic carrier 40 and the full tray receiving bin 27 to move as a whole toward the discharge port 19, so that the full tray is separated from the lifting support plate 23. At the same time, the lifting support plate 23 is withdrawn from the withdrawal port 272, so that a full tray is transferred to the full tray receiving bin 27.

[0078] The lifting support plate 23 rises to receive the next empty tray, and fills it with magnetic finished materials to obtain a full tray. The above steps are repeated to stack the full tray in the full tray receiving bin 27. The height of the full tray receiving bin 27 determines the number of stacking layers. When it is full, the operator at the discharge port 19 pulls the handle 274. When the pulling force is greater than the magnetic attraction force of the adsorption magnet 32, the drawer guide rail 31 and the full tray receiving bin 27 are separated, and the full tray receiving bin 27 slides along the drawer guide rail 31 to the discharge port 19. After taking out the full tray, the full tray receiving bin 27 is pushed in for the next material receiving.

[0079] According to a specific implementation of the utility model, the full tray receiving bin 27 is rectangular as a whole, and a raised support column 275 is respectively provided at the four corners of the bottom of the full tray receiving bin 27, and the top of the side wall of the full tray receiving bin 27 is bent outward to form a guide notch.

[0080] In specific implementation, a space for the lifting support plate 23 to move downward is formed below the raised support column 275. When the first full tray is placed in the full tray receiving bin 27, the raised support column 275 supports the bottom of the full tray, and the lifting support plate 23 continues to move downward, and the full tray is completely separated from the lifting support plate 23, which is conducive to ensuring the placement accuracy of the full tray. The guide notch is used to guide the full tray when entering, ensuring that the full tray enters the full tray receiving bin 27 smoothly.

[0081] According to a specific implementation of the utility model, the material tray 400 includes a bottom plate 401 which is rectangular as a whole; the discharge unit 200 also includes a lifting guide frame 34, which encloses a guide channel for the material tray 400 with upper and lower openings, and the cross-sectional shape of the guide channel for the material tray 400 matches the shape of the bottom plate 401; the side of the lower Y-axis telescopic power assembly away from the discharge port 19 is a material receiving station 37, the upper part of the lifting guide frame 34 is opposite to the loading station 36, and the lower part of the lifting guide frame 34 is opposite to the material receiving station 37.

[0082] In this embodiment, when the lifting support plate 23 carries the full material tray and moves from the loading station 36 to the receiving station 37, it needs to pass through the lifting guide frame 34. The lifting guide frame 34 is a limit for the full material tray to ensure the position accuracy of the full material tray and facilitate accurate cooperation with the power parts below. In specific implementation, the single-side gap between the bottom plate 401 and the side wall of the lifting guide frame 34 is small, about 0.1mm, to ensure positioning accuracy.

[0083] More specifically, two positioning sleeves 39 are respectively provided at one diagonal of the bottom plate 401, and positioning posts 38 cooperating with the two positioning sleeves 39 are respectively provided on the first upper Y-direction telescopic carrier plate 4 and the second upper Y-direction telescopic carrier plate 5. This structure is used to ensure the stability and position accuracy of the material tray 400 on the first upper Y-direction telescopic carrier plate 4 and the second upper Y-direction telescopic carrier plate 5.
