DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0026] like Figures 1 to 33In the embodiment of the magnet assembly device of the present invention shown, a magazine 10, a jig plate 110 and a magnet transfer device 20 are installed on the workbench 100 of the magnet assembly device, and the magnet transfer device 20 is used to transfer the magnet 101 in the magazine 10 to the jig plate 110; the jig plate 110 is made of ferromagnetic material, and the jig plate 110 is provided with an assembly groove 111 for arranging and placing the magnets 101 to be assembled; the magnet transfer device 20 includes a transfer base plate 21 and a transfer slide 22, the transfer slide 22 is slidably installed on the transfer base plate 21, and the transfer base plate 21 is also equipped with a transfer translation push rod 23 (pneumatic push rod or electric push rod) that drives the transfer slide 22 to slide relative to the transfer base plate 21, and the transfer slide 22 moves away from the transfer base plate 21. A groove 221 for accommodating a magnetic plate is provided on one side of the loading base plate 21. The magnetic plate is made of ferromagnetic material. A loading plate 24 that closes the groove is also installed on the side of the loading slide 22 that faces away from the loading base plate 21. A material transfer block 241 corresponding to the magnet accommodating groove on the magazine 10 is convexly provided on the bottom surface of the loading plate 24. An open groove 242 that matches the shape of the long strip magnet is provided on the loading block 241. The magnetic plate is used to adsorb the magnetized magnet in the magazine 10 into the open groove 242 at the bottom of the loading plate 24. The loading translation push rod 23 (pneumatic push rod or electric push rod) can drive the loading plate 24 to move toward the opening direction of the open groove 242 so that the magnet 101 adsorbed on the bottom of the loading plate 24 is separated from the magnet 101 in the magazine 10.

[0027] In one embodiment of the present application, Figure 1 、 Figure 3 As shown, the workbench 100 is installed with two clips 10, one clip 10 is arranged vertically, and the other clip 10 is arranged horizontally. The workbench 100 is correspondingly installed with two magnet transfer devices 20, which are used to transfer the magnets in the two clips 10 to the assembly slot 111 of the fixture plate 110.

[0028] In one embodiment of the present application, Figure 2 As shown, three long strip magnets to be assembled need to be placed in the assembly slot 111 of the jig plate 110 according to the position shown in the figure. The middle magnet is fed by the horizontally arranged clip 10, and the magnets on both sides are fed by the vertically arranged clip 10. The following takes the magnet transfer device 20 transferring the magnet 101 in the vertically arranged clip 10 to the assembly slot 111 of the jig plate 110 as an example to illustrate the working process of the magnet transfer device 20: like Figure 4As shown, the transfer plate 24 of the magnet transfer device 20 moves to the upper side of the magazine 10 loaded with magnets, and by horizontally moving the transfer base plate 21, the open groove 242 on the material transfer block 241 is aligned with the magnet 101 protruding from the top of the magazine 10, and then the transfer base plate 21 is moved downward to make the material transfer block 242 move downward along with the transfer plate 24 so that the magnet 101 to be transferred enters the open groove 242. Since the groove 221 of the transfer slide plate 22 is installed with a magnetic attraction plate (iron plate, or magnet), the top of the magnet 101 to be transferred can be adsorbed by the magnetic attraction plate on the lower surface of the transfer plate 24 and located in the open groove 242; as shown in FIG. Figure 4 As shown, the depth of the opening slot 242 along the vertical direction is less than or equal to the thickness of the magnet 101 to be transferred, that is, only one magnet 101 to be transferred can be inserted into the opening slot 242, that is, only the magnet 101 to be transferred protruding from the top of the clip 10 enters the opening slot 242, and the other magnets 101 to be transferred are still located in the clip 10, because the magnets 101 to be transferred have been magnetized, and the magnets 101 to be transferred attract each other; after the magnet 101 to be transferred protruding from the top of the clip 10 enters the opening slot 242, it is transferred by the transfer translation. The push rod 23 (pneumatic push rod or electric push rod) drives the transfer plate 24 to move toward the opening direction of the opening slot 242, so that the magnet 101 in the opening slot 242 moves horizontally with the transfer plate 24, so that the magnet 101 in the opening slot 242 is separated from other magnets 101 to be transferred in the magazine 10, thereby reliably separating the magnet 101 to be transferred from the magazine 10. During the transfer process, the position of the magnet 10 will not move and the posture will not change. The magnet can be reliably adsorbed in the opening slot at the bottom of the transfer plate 24 and will not fall off.

[0029] In the above embodiment of the present application, the magnetic attraction plate installed in the groove 221 of the transfer slide 22 is an iron plate, and the transfer base plate 21, the transfer slide 22, the transfer plate 24, etc. are all made of non-ferromagnetic materials that cannot be attracted by magnets, such as aluminum alloy; the fixture plate 110 also uses an iron plate of the same material as the magnetic attraction plate; when the magnet transfer device 20 transfers the magnet 101 to the fixture plate 110 and the transfer plate 24 is aligned with the fixture plate 110, the transfer base plate 21 is moved downward so that the bottom of the material transfer block 241 on the lower side of the transfer plate 24 is close to the upper surface of the fixture plate 110. At this time, the fixture plate 110 and the magnetic material in the groove 221 are The suction plate magnetically absorbs the magnet in the opening slot 242 at the same time. However, because the lower surface of the magnet 101 in the opening slot 242 is in direct contact with the upper surface of the jig plate 110, the upper surface of the magnet 101 in the opening slot 242 is absorbed on the lower surface of the transfer plate 24, and the distance between the magnet 101 and the magnetic suction plate in the groove 221 is the thickness of the transfer plate 24. The adsorption force of the jig plate 110 on the magnet 101 is greater than the adsorption force of the magnetic suction plate on the magnet 101. Therefore, the magnet 101 to be transferred in the opening slot 252 is transferred and adsorbed in the assembly slot 111 on the jig plate 110, thereby realizing reliable transfer of the magnet 101.

[0030] In one embodiment of the present application, preferably, Figure 8 As shown, a transfer rail 211 is also installed on the transfer base plate 21, and a transfer slider 221 adapted to the transfer rail 211 is provided on the transfer slide 22, so that the transfer slide 22 can slide reliably relative to the transfer base plate 21.

The number of material transfer blocks 251 is the same as the number of magnet receiving slots on the magazine 10, thereby enabling the simultaneous transfer of multiple magnets 101 provided by the magazine 10. Preferably, a feed guide slope is also provided on the inner lower edge of the opening slot 242, so that the magnet 101 can accurately enter the opening slot 242. The transfer plate 24 is also provided with an air vent at the bottom of the opening slot 242, so that air in the slot can be promptly discharged when the magnet 101 enters the opening slot 242, and the magnet 101 can be prevented from being adsorbed in the opening slot 242 due to negative pressure, which affects the magnet 101's separation from the transfer plate 24 during discharge.

A compression spring located between the limit plate 212 and the transfer slide 22 is also sleeved on the limit pin 213. The limit plate 213 enables the transfer slide 22 to be reliably positioned at the left end of the transfer base plate 21, and the compression spring can play a buffering role between the limit plate 213 and the transfer slide 22.

[0032] In one embodiment of the present application, preferably, Figure 6 As shown, the magnet transfer device 20 also includes a mounting vertical plate 251 and a vertical slide 252.

[0040] In one embodiment of the present application, preferably, Figure 13As shown, a magazine fixing plate 15 is installed on the upper side of the workbench 100 , and the top end of the magazine 10 is connected to the magazine fixing plate 15 .

[0041] In one embodiment of the present application, preferably, Figures 13 to 15 、 Figure 19 、 Figure 20 As shown, the workbench 100 is also equipped with a lifting assembly that drives the lifting plate 31 to move up and down. Specifically, the lifting assembly can adopt a linear lifting mechanism such as a linear stepper motor or an electric push rod. In one embodiment of the present application, the lifting assembly adopts a combination of a servo motor and a linear slide module. It uses a Panasonic 100W servo motor MSMF012L1U2M and a Hiwin KK40-200A1-F0 linear slide module. The linear slide module converts the rotational motion of the servo motor into linear motion. This combination can accurately control the distance the lifting plate moves upward each time according to the thickness of the magnet, especially for feeding and pushing magnets with smaller thickness.

[0042] In one embodiment of the present application, preferably, Figures 13 to 15 、 Figure 19 、 Figure 20 As shown, the lifting assembly is hidden and installed on the lower side of the workbench 100, and the magazine 10 is installed on the upper side of the workbench 100, so that the equipment layout is reasonable and the appearance is simple; a lifting horizontal plate 33 is installed on the lifting slider of the lifting assembly, and the lifting horizontal plate 33 is connected and fixed to the lifting plate 31 through two lifting vertical plates 34. A through hole corresponding to the lifting vertical plate 34 is provided on the workbench 100. The lifting vertical plate 34 is inserted into the through hole and the upper end is connected to the lifting plate 31, thereby the lifting plate 31 can be driven up and down by the lifting assembly.

[0043] In one embodiment of the present application, preferably, Figures 13 to 15 、 Figure 19 、 Figure 20 As shown, the workbench 100 is further provided with a guide vertical plate 35 corresponding to the lifting vertical plate 34 , a slide rail is installed on the guide vertical plate 35 , and a slider adapted to the slide rail is installed on the lifting vertical plate 34 , so that the lifting plate 31 can reliably move up and down.

[0044] In one embodiment of the present application, preferably, Figure 1 As shown, two magazines 10 are installed on the workbench 100, one of which is arranged in the vertical direction and the other is arranged in the horizontal direction. Figure 3 、 Figure 23 、 Figure 25As shown, a horizontally arranged magazine 10 is installed on the workbench 100, and a long strip of magnet 101 is filled in the horizontally arranged magazine 10. The magazine 10 is provided with a magnet receiving groove arranged in the horizontal direction, and the magnet receiving groove is filled with a plurality of magnets 101. The magnet 101 can slide horizontally in the magnet receiving groove; the magazine 10 is also provided with a translation groove 16 corresponding to the magnet receiving groove, and a feeding plate 41 capable of horizontally pushing the magnet 101 is inserted in the translation groove 16. Figure 23 、 Figure 25 As shown, the feeding plate 41 can push the magnet 101 loaded in the magnet receiving groove to the right when it moves from left to right in the translation chute 16; a vertical dividing plate 50 is also installed at the discharge end on the right side of the magazine 10, and a vertical dividing plate 50 is provided on the vertical dividing plate 50 with a vertical dividing groove 501 corresponding to the outlet of the magnet receiving groove. When the feeding plate 41 moves toward the vertical dividing plate 50 in the translation chute 16, it can push the magnet 101 in the magnet receiving groove to the vertical dividing groove 501; the vertical dividing plate 50 is also equipped with a dividing pushing vertical plate 61 for pushing the magnet 101 in the vertical dividing groove 501 upward along the vertical dividing groove 501.

[0045] In the above embodiment of the present application, the long strip magnets filled in the magnet receiving slot of the clip 10 have been magnetized, and each magnet 101 is sequentially loaded in the magnet receiving slot according to a predetermined posture and can attract each other. Figure 23 、 Figure 25 As shown, the feeding plate 41 pushes all the magnets in the magnet receiving groove to the right together so that the magnet at the rightmost end leaves the magnet receiving groove and enters the vertical dividing groove 501 on the vertical dividing plate 50, and then the magnet 101 entering the vertical dividing groove 501 is pushed upward by the dividing and pushing vertical plate 61. It can be understood that the width of the vertical dividing groove 501 is greater than the width of the magnet 101 and less than 1.5 times the width of the magnet 101, so that only one magnet 101 can slide up and down in the vertical dividing groove 501, and the width of the vertical dividing groove 501 must also ensure that the magnet 101 does not flip during the upward movement; Under the lifting action of the material dividing and pushing vertical plate 61, the magnet 101 in the vertical material dividing trough 501 is separated from the magnet 101 in the magnet receiving trough and moves upward along the vertical material dividing trough 501. The material dividing and pushing vertical plate 61 can push the magnet 101 in the vertical material dividing trough 501 upward out of the vertical material dividing plate 50, thereby efficiently and reliably feeding the magnet assembly.

[0046] like Figure 29 As shown in the figure, the upper and lower magnets 101 are displayed in the same vertical material dividing trough 501. The position shown by the magnet 101 on the lower side is the position when the magnet 101 enters the vertical material dividing trough 501 and has not been pushed upward; the position shown by the magnet 101 on the upper side is the position after the magnet 101 is lifted and pushed by the material dividing and pushing vertical plate 61.

[0047] In one embodiment of the present application, preferably, the vertical dividing plate 50 is further provided with a magnetic block 53 corresponding to the vertical dividing groove 501, and the magnetic block 53 is used to suck the magnet 101 in the magnet receiving groove of the clip 10 into the vertical dividing groove 501; specifically, when using the horizontally arranged clip 10 to feed, first fill the magnet 101 to be assembled in the magnet receiving groove of the clip 10 and fix the clip 10, and then push the magnet 101 filled in the magnet receiving groove to the outlet end of the clip through the feeding plate 41, as shown in FIG. Figure 25 As shown, when the magnet 101 filled in the magnet receiving groove moves rightward and approaches the vertical material dividing plate 50, the magnet 101 filled in the magnet receiving groove is attracted by the magnetic block 53 to enter the vertical material dividing groove 501; Figure 23 、 Figure 24 As shown, the magnetic block 53 is an elongated cylindrical shape, the magnetic block 53 is a magnet and its polarity is arranged to attract the magnet 101, or the magnetic block 53 is made of ferromagnetic materials such as iron blocks; the width of the magnet 101 is 0.4mm-0.7mm, the thickness is 0.3mm-0.8mm, and the length is 8mm-10mm, that is, the magnet 101 is a long strip of magnet with extremely small size and has been magnetized; when the feeding starts, the feeding plate 41 moves the magnet 101 loaded in the magnet receiving groove to the right and approaches the vertical dividing plate 50, and then the magnetic block 53 sucks the magnet 101 into the vertical dividing groove 501. It can be understood that the magnet container The magnets 101 loaded in the receiving groove move to the right together under the magnetic attraction of the magnetic block 53, and the magnet 101 at the rightmost end enters the vertical material dividing groove 501, and then the magnet 101 entering the vertical material dividing groove 501 is pushed upward by the material dividing and pushing vertical plate 61; after the material dividing and pushing vertical plate 61 moves upward to complete the material dividing and pushing, the material dividing and pushing vertical plate 61 moves upward and downward to reset, and under the magnetic attraction of the magnetic block 53, the magnets 101 loaded in the magnet receiving groove move to the right again and the magnet 101 at the rightmost end enters the vertical material dividing groove 501, thereby realizing the horizontal feeding, vertical material dividing and vertical pushing of the magnet 101 in a cycle.

[0048] In one embodiment of the present application, preferably, a plurality of parallel magnet receiving slots are provided on the horizontally arranged magazine 10, each of the magnet receiving slots is respectively provided with a corresponding translation slide slot 16, and each translation slide slot 16 is respectively inserted with the feed plate 41, and each feed plate 41 is fixedly connected to the translation push plate 42.

[0049] In one embodiment of the present application, preferably, Figure 25 、 Figure 26As shown, the lower end of each feed plate 41 is fixedly connected to a translation push plate 42, which is mounted on a translation slider of a translation cylinder 43 (pneumatic push rod or electric push rod). As a result, the translation cylinder 43 can drive the feed plate 41 to move within the translation chute 16. Preferably, a lifting cylinder 44 (pneumatic push rod or electric push rod) is also mounted on the translation slider of the translation cylinder 43 (pneumatic push rod or electric push rod), and the translation push plate 42 is fixedly connected to the lifting slider of the lifting cylinder 44. In this design, the translation cylinder can drive the lifting cylinder and the translation push plate to move horizontally, and the lifting cylinder can drive the translation push plate up and down, so that the translation push plate can be inserted upward into the translation chute or downward out of the translation chute.

[0050] In one embodiment of the present application, a plurality of vertical dividing grooves 501 are provided on the vertical dividing plate 50 corresponding to each of the magnet receiving grooves, and each vertical dividing groove 501 is respectively provided with a dividing pushing vertical plate 61, and the bottom end of each dividing pushing vertical plate 61 is fixedly connected to the dividing pushing horizontal plate 62, and the dividing pushing horizontal plate 62 is installed on the lifting slide of the dividing pushing cylinder 63 (pneumatic push rod, or electric push rod); thereby, the dividing pushing vertical plate 61 can be driven to move up and down by the dividing pushing cylinder 63.

After the first dividing plate 51 and the second dividing plate 52 are assembled, a vertical dividing groove 501 is formed between the end of the insert block 521 and the first opening groove 511, thereby facilitating the processing and manufacturing of the vertical dividing plate 50. As mentioned above, the width of the magnet 101 is 0.4mm-0.7mm, and the width of the vertical dividing groove 501 is slightly larger than the width of the magnet 101. The vertical dividing plate 50 is set as a split structure to facilitate the processing and formation of the above-mentioned vertical dividing groove 501.

[0052] In one embodiment of the present application, preferably, a lifting opening slide groove 522 is also provided on the plug block 521, which passes through the second material dividing plate 52 in the vertical direction. The lifting opening slide groove 522 is perpendicular to the vertical material dividing trough 501 and is connected to the vertical material dividing trough 501. The material dividing push vertical plate 61 is inserted in the lifting guide groove 522 and extends to the vertical material dividing trough 501 on one side close to the first material dividing plate 51 to push the magnet in the vertical material dividing trough 501 upward. This structure can be designed according to the needs to design the thickness of the material dividing push vertical plate 50 and the width of the lifting guide groove 522, so that the material dividing push vertical plate 61 has sufficient structural strength to avoid deformation and wear of the material dividing push vertical plate 61.

[0053] In one embodiment of the present application, Figure 31 、 Figure 32 As shown, two parallel and spaced-apart lifting opening chutes 522 are provided on the insert block 521, and a material dividing and pushing vertical plate 61 is inserted in each lifting opening chute 522. The material dividing and pushing vertical plates 61 in the two lifting opening chutes 522 move upward synchronously to push the magnet in the vertical material dividing trough 501 upward, and the magnet 101 in the vertical material dividing trough 501 is pushed upward synchronously, stably and reliably by the two material dividing and pushing vertical plates 61.

[0054] In one embodiment of the present application, preferably, Figures 23 to 29 As shown, the vertical material dividing plate 50 is installed on the material dividing base 54, and the material dividing base 54 is provided with a vertical slide rail 55, and the vertical material dividing plate 50 is provided with a slider 56 adapted to the vertical slide rail 55; the vertical material dividing plate 50 is also provided with a connecting vertical hole, and the vertical material dividing plate 50 is connected to the material dividing base 54 by a connecting limit pin 57 passed through the connecting vertical hole 5 to prevent the vertical material dividing plate 20 from separating upward from the material dividing base 54; a material dividing compression spring 58 is also provided between the vertical material dividing plate 50 and the material dividing base 54, and the bottom end of the material dividing compression spring 58 abuts against the upper side of the material dividing base 54, and the top end of the material dividing compression spring 58 abuts against the lower side of the vertical material dividing plate 50 so that the upper side of the vertical material dividing plate 50 abuts against the pin of the connecting limit pin 57. This elastic mounting structure of the vertical material dividing plate 50 enables the vertical material dividing plate 50 to move downward relative to the material dividing base 54 when pressed downward. Specifically, as mentioned above, the magnet 101 in the present application has been magnetized and has magnetism, the magnetic block 53 is a magnet or a ferromagnetic material that can be attracted by a magnet, and the other components are made of non-ferromagnetic materials that cannot be attracted by a magnet, such as aluminum alloy; in this embodiment of the present application, when the material distribution and pushing vertical plate 61 moves upward, it can push the magnet 101 in the vertical distribution trough 501 upward, and push the magnet 101 upward until the upper surface of the magnet 101 is flush with the upper surface of the vertical distribution plate 50, so that the magnet 101 is still located in the vertical distribution trough 501 and the bottom is supported by the material distribution and pushing vertical plate 61, thereby ensuring that the magnet 101 will not shake, slide, or flip Turn; when the manipulator (transfer plate) capable of adsorbing and moving the magnet 101 moves to the upper side of the vertical material dividing trough 501 and is aligned with the magnet 101 in the vertical material dividing trough 501, the manipulator (transfer plate) first moves downward to contact the upper surface of the vertical material dividing plate 50 so that the upper surface of the magnet 101 is adsorbed with the transfer plate, and then presses the vertical material dividing plate 50 to make the vertical material dividing plate 50 move downward. Since the bottom of the magnet 101 is supported by the material dividing push vertical plate 30, the magnet 101 will not move downward with the vertical material dividing plate 20, so that the magnet 101 is separated from the vertical material dividing trough 501 of the vertical material dividing plate 50, thereby ensuring accurate positioning of the magnet 101 during the transfer process.
