[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] like Figures 1 to 3 , combined Figure 8As shown, a Mylar bonding magnet assembly pressure-maintaining and unloading equipment includes a machine table 10, a feeding mechanism 20, a blocking mechanism 23, a lifting mechanism 24, a pressure-maintaining mechanism 30 and a unloading mechanism 40. The feeding mechanism 20 includes a pair of feeding lines 200 connected in series for feeding and positioning fixtures 100. The pair of blocking mechanisms 23 are matched with the pair of feeding lines 200 respectively. The blocking mechanism 23 includes a first lifting cylinder and a baffle plate arranged at the output end of the first lifting cylinder. The baffle plate is driven to rise by the first lifting cylinder to block the positioning fixture 100 transported on the feeding line 200. The pair of lifting mechanisms 24 are matched with the pair of feeding lines 200 respectively. The lifting mechanism 24 includes a second lifting cylinder and a top plate arranged at the output end of the second lifting cylinder. The cylinder drives the top plate to rise, so as to lift the positioning fixture 100 located on the feeding line 200 and blocked by the blocking mechanism 23. The pressure holding mechanism 30 is arranged on the machine table 10 and is located beside a feeding line 200. The pressure holding mechanism 30 includes a first driving unit 31 (such as a multi-axis manipulator) and a pressing plate 32 arranged at the output end of the first driving unit 31. The pressing plate 32 is driven to press the product on the lifted positioning fixture 100. The unloading mechanism 40 is arranged on the machine table 10 and is located beside another feeding line 200. The unloading mechanism 40 includes a second driving unit 41 (such as a multi-axis manipulator) and a suction cup 42 arranged at the output end of the second driving unit 41. The suction cup 42 is driven to adsorb the product on the lifted positioning fixture 100.

[0034] In the front process of the present invention, a plurality of annular magnets 101 and a plurality of strip magnets 102 are placed on the positioning jig 100 according to the position requirements, and a plurality of Mylars 103 are bonded thereon in a matching manner, so that a plurality of products consisting of annular magnets 101, strip magnets 102 and Mylars 103 are formed on the positioning jig 100. The positioning jig 100 is placed on the conveyor line 200 at the front end by manual or mechanical operation. After the positioning jig 100 is fed to the set position on the conveyor line 200, it is blocked by the blocking mechanism 23 and lifted by the lifting mechanism 24. After lifting, the first driving unit 31 drives the pressure plate 32 to press down the products on the positioning fixture 100 one by one for a set time. The pressure-maintaining action allows the Mylar and the magnet parts to fully function to ensure the connection effect. After the pressure-maintaining is completed, the blocking mechanism 23 and the lifting mechanism 24 are reset to allow the positioning fixture 100 to enter the conveyor line 200 at the rear end. Similarly, after the positioning fixture 100 is fed to the set position on the conveyor line 200, it is blocked by the blocking mechanism 23 and lifted by the lifting mechanism 24. Then, the second driving unit 41 drives the suction cup 42 to adsorb and discharge multiple products respectively.

[0035] The present invention uses a positioning fixture 100 to transport the products on two series-connected feeding lines 200 respectively, and uses a pressure-maintaining mechanism 30 to press the products, and uses a discharge mechanism 40 to discharge the pressure-maintained products, thereby improving the processing efficiency on the basis of achieving a firm combination of Mylar.

[0036] Preferably, the feeding line 200 includes a bearing part and a translation assembly 22, the bearing part is a circulating feeding belt structure with a power unit, which specifically includes a first bearing part 211 and a second bearing part 212, the second bearing part 212 is fixedly arranged on the support plate 201 on the machine 10, and its position remains fixed, the first bearing part 211 is arranged on the translation assembly 22 on the machine 10, and the translation assembly 22 drives the first bearing part 211 to move closer to or away from the second bearing part 212, thereby realizing the adjustment of the spacing between a pair of bearing parts on the feeding line 200 to be suitable for positioning fixtures 100 of different widths (that is, suitable for products of different sizes).

[0037] Specifically, the translation assembly 22 includes a mounting plate 221, a slider 222, a slide rail 223, a screw rod 224, a nut 225 and a turntable 226. The mounting plate 221 is used to support the first bearing portion 211. The slide rail 223 is arranged on the machine table 10 in a horizontal plane along a direction perpendicular to the bearing portion. The mounting plate 221 is arranged on the slide rail 223 in a translational manner through the slider 222. The nut 225 is arranged at the lower end of the mounting plate 221. The screw rod 224 is arranged perpendicular to the bearing portion in a horizontal direction. The nut 225 is arranged on the screw rod 224. The turntable 226 is arranged at one end of the screw rod 224. The screw rod 224 can be rotated by rotating the turntable 226. The screw rod 224 and the nut 225 are screwed together. The connection relationship allows the nut 225 to move along the length direction of the screw rod 224, thereby driving the mounting plate 221 and the first bearing part 211 located on the mounting plate 221 to move to adjust the spacing between a stack of bearing parts. The cost can be reduced by rotating the turntable 226 instead of the drive motor to drive the screw rod 224. Moreover, since the feeding belt on the bearing part has a certain width, for positioning fixtures 100 of different widths, only a larger part of the feeding belt is needed to support the side of the positioning fixture 100. Moreover, operation through the turntable 226 is more flexible than driving the motor, and the adjustment position is easier to flexibly control according to different positioning fixtures 100.

[0038] The mounting plate 221 includes a vertical plate 2211 and a horizontal plate 2212 arranged in the middle of the side wall of the vertical plate 2211. The lower end of the first bearing portion 211 abuts against the upper end of the horizontal plate 2212, and its side wall is locked on the vertical plate 2211, which can better ensure the stability of the first bearing portion 211 on the mounting plate 221.

[0039] Combination Figures 4 to 6As shown, in another embodiment of the present invention, the translation assembly 22 also includes a limiting member, which includes a limiting portion 227 and a limiting sheet 2281. The limiting sheet 2281 is fixedly sleeved on the screw rod 224, and a magnetic sheet 2282 is provided at one end away from the screw rod 224. The limiting portion 227 includes a positioning plate 2271 and an abutting plate 2272. The positioning plate 2271 is arranged on the mounting plate 221, and at least two abutting plates 2272 are arranged side by side and with a gap on the positioning plate 2271, and a magnet 2274 coplanar therewith is provided on the abutting plate 2272, that is, a mounting groove is provided on the abutting plate 2272, and the magnet 2274 is arranged in the mounting groove and the end face is flush with the abutting plate. In the process of driving the screw rod 224 to rotate by rotating the turntable 226 to drive the nut 225 to move, the limiting sheet 2281 on the screw rod 224 also drives the magnetic sheet 2282 Rotation, when the magnetic sheet 2282 rotates to the upper side during the rotation and is relatively adsorbed with the magnet 2274 on the abutment plate 2272, the relative stability of the screw 224 can be guaranteed at this position, and the screw 224 will not rotate by itself due to factors such as vibration generated by the positioning fixture 100 being transported on a pair of bearing parts. The stability of the screw 224 can ensure the stability of the spacing between the pair of bearing parts, and the transportation of the positioning fixture 100 can be achieved more stably; when it is necessary to adjust the spacing between a pair of bearing parts, it is only necessary to operate the turntable 226 with a slightly larger force to overcome the magnetic attraction force between the magnetic sheet 2282 and the magnet 2274; and since there are multiple matching abutment plates 2272 and magnets 2274, the magnetic sheet 2282 can be positioned at multiple positions, that is, the first bearing part 211 can be adjusted to different positions relative to the second bearing part 212.

[0040] Furthermore, the abutment plate 2272 is provided with an oblique cut 2273 at the end where the magnetic sheet 2282 rotates. Since the movement trajectory of the magnetic sheet 2282 is simultaneous rotation and translation, the oblique cut 2273 can prevent the magnetic sheet 2282 and the abutment plate 2272 from being squeezed.

[0041] In addition, the positioning plate 2271 can be provided with an arch-shaped structure, that is, a concave cavity 2270 is provided at its lower part, the end of the magnetic suction sheet 2282 can be located below the inner wall of the concave cavity 2270 and move, the abutment plate 2272 is provided in the concave cavity 2270, and its side is bonded to the positioning plate 2271, so that the lateral length of the positioning plate 2271 and the abutment plate 2272 can be reduced, and the bonding area and bonding strength between the two can be ensured; based on the above-mentioned setting, the positioning plate 2271 A first incision 227a is provided on the side close to the abutment plate 2272, and a second incision 227b is provided on the side away from the abutment plate 2272. The first incision 227a is flush with the abutment plate 2272, and the first incision 227a and the second incision 227b are staggered. The setting of the first incision 227a and the second incision 227b can enable the magnetic attraction sheet 2282 to enter or exit the concave cavity 2270 on the basis of the positioning plate 2271 with an arched structure.

[0042] like Figure 7 As shown, the pressure-maintaining blanking equipment for Mylar-bonded magnet assemblies also includes a lifting and limiting mechanism 25 arranged on the feeding line 200 and located above the lifting mechanism 24. The lifting and limiting mechanism 25 includes a vertical rod 251 and a horizontal rod 252. A pair of vertical rods 251 are symmetrically arranged on the feeding line 200, that is, they are respectively located on a pair of bearing parts. A pair of horizontal rods 252 are respectively arranged on one side of the pair of vertical rods 251 close to each other, one of the horizontal rods 252 is provided with an insertion rod 2521, and the other horizontal rod 252 is provided with a socket 2520, and the insertion rod 2521 can be translated in the socket 2520. The cross bar 252 abuts against the upper end surface of the lifted positioning fixture 100, so the joint action of the lifting mechanism 24 and the cross bar 252 can ensure the stability of the positioning fixture 100 after being lifted, especially avoiding shaking or deviation when the pressure plate 32 or the suction cup 42 acts on the product on the positioning fixture 100; and the cooperation between the socket 2520 and the insertion rod 2521 can also be used to adjust the distance between a pair of bearing parts.

[0043] The Mylar-bonded magnet assembly pressure-maintaining unloading device further includes a material receiving box 50 , which is disposed on the machine platform 10 and located beside the second driving unit 41 , and is used to collect the unloading products adsorbed by the suction cup 42 .

[0044] The pressure-maintaining unloading equipment for the Mylar-bonded magnet assembly also includes a return mechanism 61 and a return line 62 arranged next to the return mechanism 61. The return mechanism 61 includes a moving module and a suction plate arranged at the output end of the moving module. The return mechanism 61 is used to absorb the unloaded positioning fixture 100 on the feeding line 200 and move it to the return line 62. After the unloading mechanism 40 completes the unloading of the product on the positioning fixture 100, the moving module drives the suction plate to absorb the positioning fixture on the unloading line 200 and place it on the return line 62, so as to facilitate the subsequent transportation of the positioning fixture 100 with the product, so as to facilitate the movement of the unloaded positioning fixture 100 to the loading end of the entire equipment.

[0045] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
