Description

Technical Field

[0001] The utility model belongs to the technical field of motor magnet assembly production, in particular to a precise openable and closable flow transfer plate used for motor magnet assembly production. Background Art

[0002] Motor magnets are used in precision micro motors. The motor magnets include a magnet body and a yoke sheet bonded to the magnet body.

[0003] In the assembly and production of motor magnets, the solution for bonding the magnet and the yoke sheet is: manually fix the position of the magnet body, use a handheld glue gun to apply glue on the surface of the magnet body one by one, and then stick the yoke sheet on it. According to needs, manually fine-tune the position of the yoke sheet, and obtain the required motor magnet after the glue solidifies.

[0046] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. 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.

[0047] The following is combined with Figure 1-9 The utility model is further described with respect to the precision openable and closable flow carriage for assembling and producing motor magnets.

[0048] The utility model discloses a precision openable and closable flow tray for motor magnet assembly production, comprising a bearing bottom plate 8, a product positioning reference block 2 is fixedly arranged on the top of the bearing bottom plate 8, a first opening and closing unit 3 is arranged on one side of the product positioning reference block 2, and the first opening and closing unit 3 comprises: a first product positioning block 31, a first connecting plate 32, a first mounting block 33, a first closing and resetting spring 34 and a first opening limiting column 35; the first product positioning block 31 is located at the side of the positioning reference block, and the first product positioning block 31 and the product positioning reference block 2 jointly form a plurality of first product receiving grooves 4; the first connecting plate 32 is located at a 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 bottom plate 8; the first mounting block 33 is located at a side of the first connecting plate 32 away from the product positioning reference block 2; two ends of the first closing and resetting spring 34 are respectively abutted against the first mounting block 33 and the first connecting plate 32, one end of the first opening limiting column 35 is fixed to the first mounting block 33, and the other end of the first opening limiting column 35 is directly opposite to the side of the first connecting plate 32.

[0049] In this embodiment, the bearing bottom plate 8 is used to play a supporting role, the product positioning reference block 2 is fixed on the bearing bottom plate 8, and the first product positioning block 31 can be opened and closed.

[0050] When in use, the precision openable and closable flow tray for motor magnet assembly production of the utility model is placed on a production line with a multiple chain, and the multiple chain drives the precision openable and closable flow tray for motor magnet assembly production of the utility model to flow to various processes (such as loading, gluing, baking and curing, and unloading).

[0051] An external linear drive (such as a cylinder) can be used to move the first product positioning block 31 away from the product positioning reference block 2, so that the precision openable and closeable flow plate for motor magnet assembly production is in an open state. In this state, it is convenient for the manipulator to reach in and put in the magnet material (loading) or take out the assembled material (finished product unloading). The first closing reset spring 34 is compressed. The first opening limit column 35 is used for opening the limit.

[0052] Remove the additional linear drive, under the action of the first closed reset spring 34, the first product positioning block 31 moves toward the product positioning reference block 2, and the precision openable and closable flow transfer tray for motor magnet assembly production is in a closed state. In this state, the first opening and closing unit 3 presses the motor magnet 100 from the side to achieve precise positioning of the motor magnet 100, ensure the effect of dispensing and curing, and improve product quality. And the precision openable and closable flow transfer tray for motor magnet assembly production of the utility model can realize the automatic opening and closing of the first product positioning block 31, and can realize positioning of multiple products each time, and can realize automatic dispensing and bonding with the dispensing robot, which greatly reduces the labor intensity, improves the production efficiency, and can achieve precise positioning to ensure product quality.

[0053] According to a specific implementation of the utility model, a second opening and closing unit 5 which is symmetrical to the first opening and closing unit 3 is provided on the other side of the product positioning reference block 2, and 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 reset spring 54 and a second opening limit column 55; the second product positioning block 51 is located at the side of the product positioning reference block 2, and the second product positioning block 51 and the product positioning reference block 2 together form a plurality of second product receiving grooves 7; the second connecting plate 52 is located at 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 bottom plate 8; the second mounting block 53 is located at the side of the second connecting plate 52 away from the product positioning reference block 2; the two ends of the second closing reset spring 54 are respectively abutted against the second mounting block 53 and the second connecting plate 52, one end of the second opening limit column 55 is fixed to the second mounting block 53, and the other end of the second opening limit column 55 is directly opposite to the side of the second connecting plate 52.

[0054] In this embodiment, two sets of opening and closing units are used to form two sets of openable and closable product receiving slots on both sides of the product positioning reference block 2, doubling the capacity, which is conducive to improving the assembly production efficiency of the magnet. It should be noted that the second opening and closing unit 5 is symmetrical in structure with the first opening and closing unit 3, and its operating principle is the same as that of the first opening and closing unit 3. It will not be repeated here.

[0055] According to a specific embodiment of the utility model, the first opening and closing unit 3 also includes a first opening push wheel 36; the first opening push wheel 36 is installed 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 push wheel 56; the second opening push wheel 56 is installed on the second connecting plate 52 or the second product positioning block 51; the precision openable and closing flow tray for motor magnet assembly production also includes a wedge block 1 that acts on the first opening push wheel 36 and the second opening push wheel 56 at the same time, and is used to simultaneously push 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.

[0056] In this embodiment, the wedge block 1 is extended by external force, the first extension push wheel 36 and the second extension push wheel 56 are extended, the first product positioning block 31 and the second product positioning block 51 are opened, and the first closing return spring 34 and the second closing return spring 54 are compressed. When the external force acting on the wedge block 1 is removed or the external force in the opposite direction is applied to the wedge block 1, the first product positioning block 31 and the second product positioning block 51 are driven to close under the elastic force of the first closing return spring 34 and the second closing return spring 54. In specific implementation, a cylinder can be used as the power for extending and retracting the wedge block 1.

[0057] In this embodiment, a wedge block 1 and two opening push wheels (a first opening push wheel 36 and a second opening push wheel 56) are combined to push the first product positioning block 31 and the second product positioning block 51 to open synchronously, thereby ensuring the synchronization of the actions of the first product positioning block 31 and the second product positioning block 51, reducing the number of power parts and reducing the cost. The precision openable and closable flow tray for motor magnet assembly production includes an open state and a closed state.

[0058] Regarding the open state: the wedge block 1 extends to the position between the first opening push wheel 36 and the second opening push wheel 56 (the wedge block extends into the position 300), and then moves in the direction close to the product positioning reference block 2, and uses the two wedge surfaces of the wedge block 1 to simultaneously push the first opening push wheel 36 and the second opening push wheel 56, forcing the first product positioning block 31 and the second product positioning block 51 on both sides to slide in the direction away from the product positioning reference block 2 at the same time, until the first connecting plate 32 abuts against the first opening limit column 35, and the second connecting plate 52 abuts against the second opening limit column 55. At this time, the precision openable and closable flow tray for motor magnet assembly production is in the open state; the first connecting plate 32 moves while pressing the first closing reset spring 34, and the first closing reset spring 34 accumulates elastic force; the second connecting plate 52 moves while pressing the second closing reset spring 54, and the second closing 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 to put materials into the receiving slot or take materials out of the receiving slot.

[0059] Regarding the closed state: the wedge block 1 is retracted in the direction away from the product positioning reference block 2, and the first product positioning block 31 and the first connecting plate 32 are pushed to slide in the direction close to the product positioning reference block 2 under the action of the first closing reset spring 34, and stop when the first product positioning block 31 abuts against the product positioning reference block 2; at the same time, the second product positioning block 51 and the second connecting plate 52 are pushed to slide in the direction close to the product positioning reference block 2 under the action of the second closing reset spring 54, and stop when the second product positioning block 51 abuts against the product positioning reference block 2. At this time, the precision openable and closable flow transfer tray for motor magnet assembly production is in a closed state, in which all the first product receiving slots 4 and all the second product receiving slots 7 become smaller, and the magnet material is firmly received in the product receiving slots. In the utility model, the precision openable and closable flow transfer tray for motor magnet assembly production is in a closed state as a whole when it moves with the production line or performs dispensing, pressing and curing of the product, so as to ensure the accuracy of product assembly production.

[0060] According to a specific embodiment of the present utility model, the first opening and closing unit 3 also includes a first closed limiting column 37, the two ends of the first closed limiting column 37 are respectively a first fixed end 371 and a first abutting limiting end 372, the first fixed end 371 is fixed to the first connecting plate 32, and the first abutting limiting end 372 is directly opposite to one side of the bearing bottom plate 8; the second opening and closing unit 5 also includes a second closed limiting column 57, the two ends of the second closed limiting column 57 are respectively a second fixed end 571 and a second abutting limiting end 572, the second fixed end 571 is fixed to the second connecting plate 52, and the second abutting limiting end 372 is directly opposite to the one side of the bearing bottom plate 8. The contact limit end 572 is opposite to the side of the bearing base plate 8; the precision openable and closable flow transfer disc for motor magnet assembly production includes a closed state; when the precision openable and closable flow transfer disc for motor magnet assembly production is in a closed state: the first abutment limit end 372 abuts against the bearing base plate 8, and there is a gap between the first product positioning block 31 and the product positioning reference block 2, and the second abutment limit end 572 abuts against the bearing base plate 8, and there is a gap between the second product positioning block 51 and the product positioning reference block 2; the second closed limit column 57 has the same structure as the first closed limit column 37.

[0061] It should be noted that when assembling and producing magnets, the blocks need to be opened to place materials, closed to position the materials and dispense glue, then opened to stack the upper materials, and then closed again to position the materials. That is, the first product positioning block 31 and the second product positioning block 51 need to be opened and closed multiple times, and the materials need to be stacked and assembled repeatedly.

[0062] In this embodiment, the first closing limit column 37 and the second closing limit column 57 are both used for closing limit. During the closing process, when the first closing limit column 37 abuts against the bearing bottom plate 8, there is a gap between the first product positioning block 31 and the product positioning reference block 2, that is, during closing, the first closing limit column 37 hits the opposite component before the first product positioning block 31 and limits the position; the second closing limit column 57 hits the opposite component before the second product positioning block 51 and limits the position. The adoption of this structure avoids the collision between the product positioning blocks (the first product positioning block 31 and the second product positioning block 51) and the product positioning reference block 2 during closing, reduces the influence on the position of the magnet material in the product receiving cavity, and is conducive to further improving the assembly accuracy.

[0063] More specifically, the first closed limit column 37 includes a fixing nut and an adjusting screw, the fixing nut is fixed on the first connecting plate 32, one end of the adjusting screw is threadedly connected to the fixing nut, and the other end of the adjusting screw is a first abutting limit end 372; the end of the fixing nut away from the adjusting screw is a first fixed end 371. In this embodiment, the extension length of the adjusting screw can be adjusted by rotating the adjusting screw, thereby adjusting the position of the closed limit to accurately adjust the size of the first product receiving groove 4 when closed. The working principle of the second closed limit column 57 is the same as that of the first closed limit column 37, and will not be repeated.

[0064] According to a specific embodiment of the utility model, a set of first elastic clamping units 38 is correspondingly provided on one side of each first product receiving groove 4, and each first product receiving groove 4 can accommodate a motor magnet 100, and the first elastic clamping unit 38 passes through the first product positioning block 31, and one end of the first elastic clamping unit 38 abuts against the first connecting plate 32, and the other end of the first elastic clamping unit 38 extends into the first product receiving groove 4 and is used to abut the side of the motor magnet 100; a set of second elastic clamping units 58 is correspondingly provided on one side of each second product receiving groove 7, and each second product receiving groove 7 can accommodate a motor magnet 100, the second elastic clamping unit 58 passes through the second product positioning block 51, and one end of the second elastic clamping unit 58 abuts against the second connecting plate 52, and the other end of the second elastic clamping unit 58 extends into the second product receiving groove 7 and is used to abut the side of the motor magnet 100; the first elastic clamping unit 38 and the second elastic clamping unit 58 have the same structure.

[0065] In this embodiment, when the precision openable and closable flow tray for motor magnet assembly production is in a closed state, each first elastic clamping unit 38 abuts against the side of a motor magnet 100, applies elastic force to each motor magnet 100, and pushes each motor magnet 100 to align inward, thereby ensuring the accuracy of the position of each motor magnet 100, achieving precise positioning of the high motor magnet, and ensuring high repeated positioning accuracy during repeated positioning. The working principle of the second elastic clamping unit 58 is the same as that of the first elastic clamping unit 38, which will not be repeated here.

[0066] According to a specific embodiment of the present utility model, the first elastic clamping unit 38 includes a first compression spring 381 and a first pressure column 382. The first product positioning block 31 is provided with a first clamping unit receiving hole running through it. The first clamping unit receiving hole is composed of a connected 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 pressure column 382 includes a first clamping shaft section and a first telescopic shaft section that are fixedly connected. The first compression spring 381 and the first clamping shaft section are both received in the first spring hole 311.

The second compression spring 581 and the second clamping shaft section are both received in the second spring hole 511, and the second telescopic shaft section extends into the second axial hole 512.

[0067] This embodiment further defines the structure of the first elastic clamping unit 38 and the second elastic clamping unit 58. The structure and operation principle of the first elastic clamping unit 38 and the second elastic clamping unit 58 are the same, and the first elastic clamping unit 38 is used as an example for explanation below. When the first compression spring 381 is in a free state, the first telescopic shaft section extends a distance from the receiving hole of the first shaft hole 312, and the first elastic clamping unit 38 moves toward the product positioning reference block 2 as a whole along with the first product positioning block 31 and the first connecting plate 32, until the precision openable and closable flow tray used for motor magnet assembly production is in a closed state, the first telescopic shaft section abuts against the motor magnet 100 and squeezes the first compression spring 381, and finally the first pressure column 382 applies an elastic force to each motor magnet 100.

[0068] According to the specific implementation mode of the utility model, a plurality of recessed product fixing grooves 21 are respectively provided on both sides of the product positioning reference block 2; a first movable recessed groove 313 is correspondingly provided on one side of the first product positioning block 31 close to the product fixing groove 21, and the product fixing groove 21 and the first movable recessed groove 313 form a first product receiving groove 4; a second movable recessed groove 513 is correspondingly provided on one side of the second product positioning block 51 close to the product fixing groove 21, and the product fixing groove 21 and the second movable recessed groove 513 form a second product receiving groove 7.

[0069] In this embodiment, the product positioning reference block 2 and the first product positioning block 31 and the second product positioning block 51 respectively form a plurality of product receiving grooves for receiving products, and the shapes of the product receiving grooves match the shapes of the products to be received and clamped.

[0070] According to a specific embodiment of the present invention, the first product receiving groove 4 and the second product receiving groove 7 are both rectangular in shape as a whole.

[0071] More specifically, the cross section of the motor magnet 100 is fan-shaped, and multiple motor magnets 100 can be subsequently formed into a ring shape and used as motor assembly accessories. The upper and lower surfaces of the motor magnet 100 are arc surfaces, and when assembled, it is inverted in the product receiving groove, and the projection of the motor magnet 100 on the bottom surface of the receiving groove is a rectangle.

[0072] 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 projection shape of the motor magnet 100 on the bottom surface of the receiving groove.

[0073] According to a specific embodiment of the utility model, the bearing base plate 8 includes a base plate body 81 which is a flat plate as a whole, 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 by connecting the positioning piece, the first opening and closing unit 3 and the second opening and closing unit 5 are both installed on the upper part of the base plate body 81, and the first opening and closing unit 3 and the second opening and closing unit 5 are respectively installed on both sides of the reference block support platform 82; the first opening and closing unit 3 also includes a first sliding component 39 arranged between the base plate body 81 and the first connecting plate 32 and used to realize the sliding connection between the first connecting plate 32 and the bearing base plate 8; the second opening and closing unit 5 also includes a second sliding component 59 arranged between the base plate body 81 and the second connecting plate 52 and used to realize the sliding connection between the second connecting plate 52 and the bearing base plate 8; a clamping cover 9 for hoisting is also provided at both ends of the upper part of the reference block support platform 82.

[0074] In this embodiment, the reference block support platform 82 is raised, which, on the one hand, raises the position of the product positioning reference block 2, and is conducive to providing installation space for the first sliding assembly 39 and the second sliding assembly 59. In specific implementation, a transfer robot is provided on the production line, and the transfer robot has two forks used in conjunction with two clamping covers 9. The top of the clamping cover 9 has a cover top step protruding to the side. The fork is inserted under the cover top step and lifted up, and the clamping cover 9 and the entire precision openable and closable flow tray for motor magnet assembly production can be lifted and transferred to the next station.

[0075] According to the specific implementation mode of the present utility model, a recessed sleeve hole 821 is provided at the bottom of the reference block support platform 82, and a positioning sleeve 10 which is annular as a whole is provided in the sleeve hole 821; the bottom plate body 81 is rectangular as a whole, and a stop column 13 is respectively provided at the four corners of the upper part of the bottom plate body 81, and the upper part of the stop column 13 is higher than the upper part of the product positioning reference block 2; the first support push wheel 36 is installed at the lower part of the first connecting plate 32, and the second support push wheel 56 is installed at the lower part of the second connecting plate 52.

[0076] In this embodiment, the positioning sleeve 10 is used to cooperate with the top column of the jacking structure located below the precision openable and closed flow transfer disc for motor magnet assembly production. The two top columns extend and are respectively inserted into the two positioning sleeves 10, so that the precision openable and closed flow transfer disc for motor magnet assembly production is lifted up as a whole and separated from the multiple chain. At the same time, the upper surface of the stop column 13 hits the pressure column fixed at the corresponding position of the production line to achieve the upper limit. With this structure, under the cooperation of the production line jacking structure and the pressure column, the precision openable and closed flow transfer disc for motor magnet assembly production of the utility model can be firmly positioned at a certain place of the multiple chain to meet the production line requirements. The stop column 13 also includes another aspect of the function: when the precision openable and closed flow transfer disc for motor magnet assembly production of the utility model crosses two connected multiple chains, it is sometimes necessary to set a push rod on the production line. The stop column 13 is used to provide a force application point. The push rod acts on one side of the stop column 13 to push the precision openable and closed flow transfer disc for motor magnet assembly production of the utility model to move as a whole and cross the multiple chain.

[0077] When the precision opening and closing flow-through transfer tray for motor magnet assembly production of the utility model is used in an occasion where it needs to cross two connected multiple chains, since there is a certain gap between the two adjacent multiple chains, the bottom chamfer 62 is conducive to smoothly guiding the precision opening and closing flow-through transfer tray for motor magnet assembly production of the utility model from one multiple chain to another multiple chain, avoiding the lower part of the wear-resistant strip 6 from getting stuck during the transfer. The side chamfer 61 is also conducive to smoothly guiding the precision opening and closing flow-through transfer tray for motor magnet assembly production of the utility model from one multiple chain to another multiple chain, avoiding the side wall of the wear-resistant strip 6 from getting stuck during the transfer.

[0078] More specifically, a spreading limit block 11 for limiting the extension length of the wedge block 1 is fixedly embedded on one side of the bottom of the reference block support platform 82 , and a limit collision block 12 is fixedly embedded on one side of the bottom of the reference block support platform 82 .

[0079] In this embodiment, when the wedge block 1 is extended to a preset length, the wedge block 1 abuts against the expansion limit block 11. With this structure, the extension length of the wedge block 1 can be adjusted by adjusting the installation position of the expansion limit block 11, and the size of the receiving groove in the open state can be further adjusted. The limit collision block 12 is used to cooperate with the limit cylinder on the production line to achieve limiting. Specifically: when the limit rod of the limit cylinder is extended, it abuts against the limit collision block 12, limiting the precision openable and closed circulation conveyor for motor magnet assembly production of the utility model from continuing to move forward along the transmission direction of the multiple chain. After adopting the expansion limit block 11 and the limit collision block 12, the bearing bottom plate 8 can also be prevented from being directly hit, and the expansion limit block 11 and the limit collision block 12 can be selected separately from impact-resistant or vibration-absorbing materials, and can be replaced separately after being damaged, which greatly improves the overall performance of the circulation conveyor.

[0080] More specifically, the precision openable and closing flow transfer plate used for motor magnet assembly production also includes two wear-resistant strips 6 respectively arranged on both sides of the lower part of the base plate body 81. The wear-resistant strip 6 is rectangular as a whole, and the four corners of the wear-resistant strip 6 are respectively provided with side chamfers 61, and the bottoms of the two ends of the wear-resistant strip 6 in the length direction are respectively provided with bottom chamfers 62.

[0081] In this embodiment, after the wear-resistant strip 6 is added, the wear-resistant strip 6 replaces the bearing bottom plate 8 to contact the multiple chains. When in use, the wear-resistant strip 6 is in direct contact with the roller on the multiple chains. The wear-resistant strip 6 is made of plastic material, which can increase the contact friction between the wear-resistant strip 6 and the roller, which is beneficial for the multiple chains to drive the precise openable and closable flow tray for motor magnet assembly production to move. After the wear-resistant strip 6 is used, the wear of the lower part of the bearing bottom plate 8 can be avoided. After the wear-resistant strip 6 is worn out after long-term use, the wear-resistant strip 6 can be directly replaced.

[0082] More specifically, the connection positioning member includes positioning pins and screws arranged alternately. Two sleeve holes 821 are arranged at intervals, and a positioning sleeve 10 is arranged in each sleeve hole 821. The first sliding assembly 39 is the same as the second sliding assembly 59, and the first sliding assembly 39 includes a guide rail and a slider matched with the guide rail.
