DETAILED DESCRIPTION

[0036] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0037] A pusher device for a special magnet assembly 11, such as Figures 1 to 18As shown, it includes a workbench 1, a first magnetic material clamp 2, a second magnetic material clamp 3, a limiting device 4, a first pushing device 5, a second pushing device 6 and a moving device 7; the first magnetic material clamp 2 and the second magnetic material clamp 3 are respectively fixed on the workbench 1, and a vertical arrangement is formed between the first magnetic material clamp 2 and the second magnetic material clamp 3 in the longitudinal and transverse directions. The tops of the first magnetic material clamp 2 and the second magnetic material clamp 3 are both provided with a feeding port 8 for pre-installed magnets, and the bottoms of the first magnetic material clamp 2 and the second magnetic material clamp 3 are both provided with a discharge port 9; the limiting device 4 is fixedly arranged on the workbench 1, and a limiting portion 43 is provided on the limiting device 4, and the limiting portion 4 3 corresponds to the position of the discharge port 9 of the first magnetic material clamp 2 and the discharge port 9 of the second magnetic material clamp 3; the first pushing device 5 and the second pushing device 6 are respectively arranged on the workbench 1, the first magnetic material clamp 2 is located between the limiting device 4 and the first pushing device 5, the second magnetic material clamp 3 is located between the limiting device 4 and the second pushing device 6, the first pushing device 5 and the second pushing device 6 are used to push the magnets of the discharge port 9 against the limiting part 43 of the limiting device 4 to form a magnet assembly 11; the material moving device 7 is arranged on the workbench 1, and is used to carry the magnet assembly 11 arranged on the limiting device 4.

[0038] In this embodiment, since the magnets need to be assembled into an L-shaped magnet assembly 11, the first magnetic material clip 2 and the second magnetic material clip 3 are arranged vertically in the longitudinal and transverse directions. The first magnetic material clip 2 is arranged vertically and can accommodate four magnets, and the second magnetic material clip 3 is arranged horizontally and can accommodate three magnets, but it is not limited to this. In other embodiments, the number of magnets accommodated by the first magnetic material clip 2 and the second magnetic material clip 3 can also be adjusted according to actual needs. For example, the first magnetic material clip 2 is set to accommodate three magnets, and the second magnetic material clip 3 is set to accommodate four magnets. The magnets arranged in a row are respectively placed from the feed ports 8 of the first magnetic material clamp 2 and the second magnetic material clamp 3, and will sink to the discharge port 9 under the action of their own gravity. The first pushing device 5 and the second pushing device 6 respectively push the magnets at the discharge ports 9 of the first magnetic material clamp 2 and the second magnetic material clamp 3 against the limiting device 4. The shape of the limiting device 4 matches the shape of the magnet assembly 11, so that the magnet forms an L-shaped magnet assembly 11, and then the magnet assembly 11 on the limiting device 4 is moved to the fixture through the material moving device 7. The whole process is semi-automated, which effectively reduces the burden of manual operation, improves the production efficiency and production quality of the magnet assembly 11, and is conducive to the smooth progress of the next step of dispensing and bonding iron parts.

[0039] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a cover plate 12 is provided on the workbench 1, a first magnetic material clamp 2 and a second magnetic material clamp 3 are fixedly arranged at adjacent two sides of the cover plate 12, a limiting device 4 is fixedly arranged on the cover plate 12, and a first magnetic attraction plate 13 for adsorbing the magnet assembly 11 on the cover plate 12 is provided at the bottom of the cover plate 12.

[0040] A cover plate 12 is provided on the workbench 1 of this embodiment to prevent the magnet assembly 11 from directly contacting the workbench 1 and causing wear of the magnet assembly 11. The limiting device 4 is fixedly arranged on the cover plate 12, and the first magnetic material clamp 2 and the second magnetic material clamp 3 are fixedly arranged at the positions on the adjacent two sides of the cover plate 12, and are arranged vertically in the longitudinal and transverse directions, so that the first pushing device 5 and the second pushing device 6 can push the magnet against the limiting device 4 to form an L-shaped magnet assembly 11. This embodiment also provides a first magnetic suction plate 13 at the bottom of the cover plate 12. The suction force provided by the first magnetic suction plate 13 flatly adsorbs the entire row of magnets on the cover plate 12, so that the magnets of the first magnetic material clamp 2 and the second magnetic material clamp 3 will not be offset during the process of being pushed by the first pushing device 5 and the second pushing device 6, thereby ensuring the fit between the magnet assembly 11 and the fixture.

[0041] like Figure 2 , Figure 3 and Figure 8 As shown, the limiting device 4 includes a first limiting block 41 and a second limiting block 42. The first limiting block 41 is provided with the limiting portion 43. The limiting portion 43 is stepped. The first pushing device 5 and the second pushing device 6 respectively push the magnets of the first magnetic material clamp 2 and the second magnetic material clamp 3 to rest between the limiting portion 43 of the first limiting block 41 and the second limiting block 42, thereby forming an L-shaped magnet assembly 11.

[0042] The first limit block 41 of the present embodiment is provided with a stepped limit portion 43, which corresponds to the discharge port 9 of the first magnetic material clamp 2 and the discharge port 9 of the second magnetic material clamp 3, and is in the same straight line as the first pushing device 5 and the second pushing device 6. The first pushing device 5 and the second pushing device 6 respectively push the magnets of the first magnetic material clamp 2 and the second magnetic material clamp 3 to rest between the limit portion 43 of the first limit block 41 and the second limit block 42, thereby forming an L-shaped magnet assembly 11, which has a simple structure and is easy to implement.

[0043] like Figure 5 , Figure 6 and Fig.11As shown, the first magnetic attraction plate 13 of this embodiment is provided with anti-stupid magnet openings 14 at positions corresponding to the discharge ports 9 of the first magnetic material clamp 2 and the second magnetic material clamp 3, respectively. The anti-stupid magnet is arranged in the anti-stupid magnet openings 14 and is located at the bottom of the cover plate 12. When a whole row of magnets is placed from the feed port 8 of the first magnetic material clamp 2 or the second magnetic material clamp 3, the magnets will sink to the discharge port 9 under the action of their own gravity. Since the polarity of the anti-stupid magnet is opposite to the polarity of the corresponding magnet at the discharge port 9, the whole row of magnets at the discharge port 9 can be flatly adsorbed on the cover plate 12, which is convenient for the operator to pre-install the magnets. The first magnetic attraction plate 13 of this embodiment is provided with an anti-stupid magnet opening 14 at positions corresponding to the discharge ports 9 of the first magnetic material clamp 2 and the second magnetic material clamp 3, respectively, but it is not limited thereto. In other embodiments, multiple anti-stupid magnet openings 14 can be provided according to actual needs, and the anti-stupid magnets are adaptively arranged.

[0044] like Fig. 9 and Fig.10 As shown, in this embodiment, a discharge trough 10 is provided at the discharge port 9 of the first magnetic material clamp 2 and the second magnetic material clamp 3. The longitudinal height of the discharge trough 10 is greater than the longitudinal height of the pre-installed magnet. The longitudinal height of the discharge trough 10 is preferably greater than the longitudinal height of the magnet by 0.5 mm, but is not limited thereto. This ensures that when the first pushing device 5 and the second pushing device 6 push out the magnet, the magnets in the first magnetic material clamp 2 and the second magnetic material clamp 3 will not get stuck, and the design is user-friendly.

[0045] like Figure 3 and Fig.17 As shown, the first pushing device 5 includes a first pushing cylinder 51 and a first shovel plate 52. The output end of the first pushing cylinder 51 is provided with a push rod, and the first shovel plate 52 is fixedly arranged on the push rod. The first pushing cylinder 51 controls the push rod to make reciprocating motion, so that the first shovel plate 52 cyclically pushes the magnet of the first magnetic material clamp 2 against the limiting portion 43 of the limiting device 4. The second pushing device 6 includes a second pushing cylinder 61 and a second shovel plate 62. The output end of the second pushing cylinder 61 is provided with a push rod, and the second shovel plate 62 is fixedly arranged on the push rod. The second pushing cylinder 61 controls the push rod to make reciprocating motion, so that the second shovel plate 62 repeatedly pushes the magnet of the first magnetic material clamp 2 against the limiting portion 43 of the limiting device 4.

[0046] The first pushing device 5 and the second pushing device 6 of this embodiment use the first pushing cylinder 51 and the second pushing cylinder 61 as the power source, and have good power output. The first shovel plate 52 and the second shovel plate 62 cooperate with the first pushing cylinder 51 and the second pushing cylinder 61 to ensure that the whole row of magnets can be stably against the limit device 4. In this embodiment, the size of the first shovel plate 52 and the second shovel plate 62 should match the size of the discharge trough 10 at the discharge port 9 and the whole row of magnets, so that the magnets are more evenly stressed when the first shovel plate 52 and the second shovel plate 62 push the whole row of magnets.

[0047] like Fig.12 As shown, the material moving device 7 includes a transport cylinder 71, a lifting cylinder 72 and a demagnetization cylinder 73. A side plate 21 is fixedly provided on the left side of the workbench 1. The transport cylinder 71 is slidably set on the side plate 21 along the front and rear directions of the workbench 1. The lifting cylinder 72 is fixedly set on the transport cylinder 71, and the output end of the lifting cylinder 72 is set vertically downward. The demagnetization cylinder 73 is set at the output end of the lifting cylinder 72, and the output end of the demagnetization cylinder 73 is set vertically downward.

[0048] by Fig.16 and Fig.17 The figure shows a reference datum. In this embodiment, a side plate 21 is fixedly provided on the left side of the workbench 1. The transport cylinder 71 is slidably arranged on the side plate 21 along the front-back direction of the workbench 1 and is located above the side of the workbench 1. The lifting cylinder 72 is arranged on the transport cylinder 71. When the transport cylinder 71 slides along the front-back direction of the workbench 1, the lifting cylinder 72 slides with the sliding of the transport cylinder 71. The output end of the lifting cylinder 72 is arranged vertically downward, which can provide a long distance of displacement, and is convenient for carrying the magnet assembly 11 arranged on the limit device 4. The demagnetization cylinder 73 is arranged at the output end of the lifting cylinder 72. The output end of the demagnetization cylinder 73 is arranged vertically downward, which is convenient for the output end of the demagnetization cylinder 73 and the lifting cylinder 72 to produce relative movement, so that the magnet assembly 11 is easier to fall off.

[0049] like Figures 12 to 15 As shown, it also includes a second magnetic attraction plate 74, a connecting plate 75 and a demagnetizing plate 76. The second magnetic attraction plate 74 is arranged at the output end of the demagnetizing cylinder 73. A plurality of magnetic attraction columns 77 are arranged at the bottom of the second magnetic attraction plate 74. The demagnetizing cylinder 73 is connected to the lifting cylinder 72 through the connecting plate 75. The bottom of the connecting plate 75 is fixedly connected to the top of the demagnetizing plate 76. A boss 78 matching the shape of the magnet assembly 11 is arranged at the bottom of the demagnetizing plate 76. A plurality of through holes matching the magnetic attraction columns 77 are arranged on the demagnetizing plate 76. The magnetic attraction columns 77 of the second magnetic attraction plate 74 are movably inserted into the through holes of the demagnetizing plate 76. The bottom ends of the magnetic attraction columns 77 are flush with the bosses 78 at the bottom of the demagnetizing plate 76, which are used to absorb the magnet assembly 11 on the limiting device 4. The demagnetizing cylinder 73 drives the magnetic attraction columns 77 to rise and disengage from the through holes of the demagnetizing plate 76. The demagnetizing plate 76 is used to isolate the second magnetic attraction plate 74 and the magnet assembly 11.

[0050] The second magnetic plate 74 of this embodiment is provided with a plurality of magnetic posts 77 at the bottom, but is not limited thereto. The shape formed by the plurality of magnetic posts 77 matches the shape of the magnet assembly 11, and each magnetic post 77 corresponds to a magnet, so that the second magnetic plate 74 can better absorb the magnet assembly 11. The demagnetizing plate 76 is provided with a boss 78 matching the shape of the magnet assembly 11 at the bottom, and the demagnetizing plate 76 is provided with a through hole matching the magnetic post 77. The magnetic post 77 of the second magnetic plate 74 passes through the through hole of the demagnetizing plate 76, and the bottom end of the magnetic post 77 is flush with the boss 78 at the bottom of the demagnetizing plate 76. The demagnetization cylinder 73 of this embodiment is connected to the lifting cylinder 72 through a connecting plate 75, and the bottom of the connecting plate 75 is fixedly connected to the top of the demagnetization plate 76. When the demagnetization cylinder 73 drives the second magnetic plate 74 together with the magnetic column 77 to rise, since the demagnetization plate 76 is made of non-magnetic material, the magnet assembly 11 at the bottom of the demagnetization plate 76 can be separated from the magnetic column 77, thereby achieving a demagnetization operation.

[0051] like Figure 1 , Fig.16 and Fig.17 As shown, in order to receive the arranged magnet assemblies 11, this embodiment also includes a jig plate 15, a slide 16, a guide rail 17 and a driving assembly 18 for driving the guide rail 17. A bottom plate 20 is provided below the workbench 1, the guide rail 17 is mounted on the bottom plate 20, the slide 16 is slidably arranged on the guide rail 17, the jig plate 15 is fixedly arranged on the slide 16, and a plurality of placement grooves 19 for placing the magnet assemblies 11 are evenly distributed on the jig plate 15. The driving assembly 18 drives the guide rail 17 to rotate so that the slide 16 moves laterally along the guide rail 17, and the slide 16 moves so that the placement grooves 19 on the jig plate 15 are aligned with the magnet assemblies 11 on the material transfer device 7. The arranged magnet assemblies 11 are moved and fixed on the placement grooves 19 of the jig plate 15 under the drive of the material transfer device 7, and then the slide 16 continues to move laterally for a distance for the next group of arranged magnet assemblies 11 to be placed, thereby realizing automated operation.

[0052] Further, if Figure 1 As shown, in this embodiment, a dust cover 22 is also provided on the workbench 1, but it is not limited thereto. It can not only effectively prevent pollutants from entering the equipment and extend the service life of the equipment, but also improve the safety of manual operation. The height of the dust cover 22 is lower than the height of the first magnetic material clamp 2 and the second magnetic material clamp 3, and a through hole for the first magnetic material clamp 2 and the second magnetic material clamp 3 to pass through is provided at the position of the first magnetic material clamp 2 and the second magnetic material clamp 3. The feed port 8 of the first magnetic material clamp 2 and the second magnetic material clamp 3 is located at the top of the dust cover 22, which is convenient for manual pre-installation of magnets.

[0053] Further, if Figure 1 , Fig.16 and Fig.17As shown, in this embodiment, a control module 23 is also set on the workbench 1, and the control module 23 is electrically connected to the motor (not shown in the figure), and the motor is electrically connected to the first pushing cylinder 51, the second pushing cylinder 61, the transport cylinder 71, the lifting cylinder 72, the demagnetization cylinder 73 and the driving assembly 18 respectively, and the control module 23 controls each module through the motor to realize semi-automatic operation.

[0054] Taking three magnets arranged horizontally and four magnets arranged vertically as an example, the working process of the utility model is as follows:

[0055] After a single magnet is magnetized, it will attract each other into a row according to its polarity, such as Figure 7 As shown, among the three magnets arranged horizontally, the magnet polarity at both ends is S pole, and among the four magnets arranged vertically, the magnet polarity is adaptively adjusted. The four magnets arranged vertically are placed in the first magnetic material clamp 2, and the three magnets arranged horizontally are placed in the second magnetic material clamp 3. Since the first magnetic attraction plate 13 is provided on the workbench 1, the four magnets of the first magnetic material clamp 2 and the three magnets of the second magnetic material clamp 3 can be flatly adsorbed on the cover plate 12 under the action of their own gravity and the first magnetic attraction plate 13. Press the start switch of the control module 23, and the first push cylinder 51 and the second push cylinder 61 start to work, respectively driving the first shovel plate 52 and the second shovel plate 62 to move. The first shovel plate 52 and the second shovel plate 62 push the four magnets at the discharge port 9 of the first magnetic material clamp 2 and the three magnets at the discharge port 9 of the second magnetic material clamp 3 to between the limiting portion 43 of the first limiting block 41 and the second limiting block 42. Since the limiting portion 43 is in a stepped shape, the three magnets arranged horizontally and the four magnets arranged vertically form an L-shaped magnet assembly 11 at the limiting portion 43. Figure 3 shown.

[0056] After the material is pushed, the magnet assembly 11 on the limiting device 4 is placed in an L shape. At this time, the initial position of the transport cylinder 71 is close to one end of the magnet assembly 11. Fig.16 As shown, the demagnetization cylinder 73 is in a descending state, the bottom of the second magnetic plate 74 is against the top of the demagnetization plate 76, and the magnetic column 77 is flush with the boss 78 at the bottom of the demagnetization plate 76. Then the first push cylinder 51 and the second push cylinder 61 are reset respectively, the lifting cylinder 72 descends, and the second magnetic plate 74 adsorbs the magnet assembly 11 to the bottom of the demagnetization plate 76 through the magnetic column 77. Then the lifting cylinder 72 rises, and the transport cylinder 71 moves to the top of the fixture plate 15. After the transport cylinder 71 moves into place, the lifting cylinder 72 descends, as shown in FIG. Fig.17 After the lifting cylinder 72 is lowered to the position, the demagnetizing cylinder 73 rises and drives the second magnetic plate 74 and the magnetic column 77 to rise. Since the demagnetizing plate 76 is made of non-magnetic material, the magnet assembly 11 will remain in the placement groove 19 of the fixture plate 15 as a whole. Fig.18Then the lifting cylinder 72 rises, and the driving assembly 18 drives the guide rail 17 to drive the fixture plate 15 on the slide 16 to move horizontally for a distance, so that the next group of arranged magnet assemblies 11 can be placed, and the operation is cyclic.

[0057] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0058] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
