Description

Technical Field

[0001] The utility model relates to the technical field of processing devices, in particular to a multi-station heating and pressing machine. Background Art

[0002] Magnets are widely used in the fields of electronics, mechanical equipment, medical treatment, automobiles, electroacoustics, motors, etc. By arranging or assembling multiple magnets according to different polarities into different magnetic group structures (such as Halbach structure, etc.), a stronger magnetic field can be obtained with the least amount of magnetism and the smallest volume. When multiple magnets are arranged or assembled in combination, anaerobic glue, AB glue, resin glue and other glues are generally used for bonding. The uniformity of glue coating and the thickness of the glue layer will affect the bonding force between the parts. Some application scenarios also have shielding requirements or structural fixation requirements for the magnetic field direction or a certain direction of the magnet, and it is necessary to bond a magnetic steel plate or a shielding steel plate or a fixed steel plate to the magnetic group structure. During the magnet assembly process, it is generally necessary to use a jig to fix and limit the magnets, steel plates and other parts before applying glue and bonding to ensure that the dimensional tolerances meet the design requirements. Different types of glue have corresponding requirements for curing time and curing temperature. For example, AB two-component glue generally takes 24 hours to fully cure at room temperature, but at 80 degrees Celsius, the full curing time can be shortened to about 30 minutes, and 50% curing can be achieved in about 5 minutes.

[0003] Existing magnetic group bonding and curing devices generally use a single station for curing processing. In the case of large-scale production, multiple curing devices and multiple personnel are required to process the bonded magnetic groups, which has low production efficiency and is inconvenient for users.

[0026] The replacement mechanism includes a first connecting column 1001, one end of the first connecting column 1001 is fixedly connected to the second cylinder 1002, one side of the second cylinder 1002 is fixedly connected to the base 1, and the top of the first fixture 7 is fixedly connected to the first fixing block 1003.

[0027] A second fixing block 1004 is fixedly connected to the top of the second fixture 8 , and a second connecting column 1005 is fixedly connected between the first fixing block 1003 and the second fixing block 1004 .

[0028] The electrical control box 3 is composed of a digital controller 301 and a temperature controller 302. The digital controller 301 is fixedly connected to one side of the bracket 2, and the temperature controller 302 is fixedly connected to the other side of the bracket 2. The digital controller 301 is electrically connected to the first cylinder 4 through a wire. When the processing time set by the digital controller 301 is reached, the first cylinder 4 can drive the heating device 6 to move upward and separate from the magnetic group 9.

[0029] The downward pressure device 5 is composed of an upper pressure plate 501, a guide column 502, a spring 503 and a lower pressure plate 504. The top of the upper pressure plate 501 is fixedly connected to the output end of the first cylinder 4, the guide column 502 is fixedly connected to the inside of the upper pressure plate 501, and the spring 503 is sleeved on the outside of the guide column 502. One end of the spring 503 is fixedly connected to the upper pressure plate 501, and the other end of the spring 503 is fixedly connected to the lower pressure plate 504. One end of the guide column 502 passes through the interior of the lower pressure plate 504 and is slidably connected to the lower pressure plate 504. The lower pressure plate 504 and the upper pressure plate 501 are elastically connected by the spring 503, so that the lower pressure plate 504 can play a buffering role after being fitted with the jig through the heating device 6, and the elastic force of the spring 503 can ensure that the two fit more closely to avoid gaps.

[0030] The heating device 6 is composed of a heating plate 601, a temperature measuring thermistor 602 and a heating rod 603.

After the heating plate 601 is attached to the first fixture 7, a closed space is formed between the two. As the temperature inside the heating plate 601 increases, the pressure inside it will also increase.

[0031] The top of the first fixture 7 is fixedly connected to the first concave plate 11 by bolts, and a first groove is provided in the first concave plate 11, and the first groove is clearance-matched with the magnetic group 9. The top of the second fixture 8 is fixedly connected to the second concave plate 12 by bolts, and a second groove is provided on the top of the second concave plate 12. The second groove has a different shape from the first groove, and can accommodate magnetic groups 9 of different shapes for curing processing. The magnetic group 9 is placed in the first concave plate 11, and the magnetic group 9 consists of a first magnet 901, a second magnet 902, a third magnet 903 and a steel sheet 904. The first magnet 901, the second magnet 902 and the third magnet 903 are all bonded to the steel sheet 904.

[0032] The inner portion of the bracket 2 is slidably connected to the limiting column 13 , one end of which is fixedly connected to the upper pressing plate 501 , and the outer portion of the limiting column 13 is slidably connected to the limiting sleeve 14 , one side of which is fixedly connected to the top of the bracket 2 .

[0033] By setting the limit column 13 and the limit sleeve 14, the limit column 13 and the bracket 2 can slide up and down to play a limiting role when the pressing device 5 moves up and down, preventing the pressing device 5 from shaking and shifting when moving up and down, and the limit sleeve 14 can strengthen the connection between the limit column 13 and the bracket 2.

[0034] Working principle: When curing the bonded magnetic group 9, first, the magnetic group 9 coated with glue and loaded into the steel sheet 904 is placed on the top of the first jig 7 and clamped into the first groove on the top of the first concave plate 11. Then, the first cylinder 4 is started, and the first cylinder 4 drives the pressing device 5 and the heating device 6 and other components to move downward and press the magnetic group 9. Then, after the time set by the digital controller 301 is reached, the first cylinder 4 drives the pressing device 5 and the heating device 6 to retract, completing the glue bonding and pressure holding process of the magnetic group 9.

[0035] By setting up a plurality of first cylinders 4, the plurality of first cylinders 4 are evenly distributed on the top of the bracket 2. Each first cylinder 4 can solidify and process the magnetic group 9 in batches through the corresponding pressing device 5 and heating device 6 at the bottom of the air cylinder. There are multiple first grooves on the top of the first concave plate 11. Each heating device 6 can process the magnetic groups 9 in multiple first grooves, further increasing the number of magnetic groups 9 processed. The multi-station production design scheme can effectively improve the production efficiency of the magnetic group 9 while reducing the number of operators.

[0036] When it is necessary to manufacture a special-shaped magnetic group 9, the second cylinder 1002 is started, and the second cylinder 1002 drives the first fixed block 1003 to move backward through the first connecting column 1001. The first fixed block 1003 drives the first jig 7 at the bottom and the second connecting column 1005 on the front side to move backward. The second connecting column 1005 simultaneously drives the second fixed block 1004 and the second jig 8 at the bottom of the second fixed block 1004 to move backward, so that the second jig 8 is located at the bottom of the heating device 6 after moving backward. At this time, the heating device 6 will be pressed down and fit with the second concave plate 12 at the top of the second jig 8, so as to achieve the effect of quick replacement of jigs, and can quickly replace jigs of magnetic groups 9 of different shapes without affecting the overall processing time. The first concave plate 11 on the top of the first jig 7 and the second concave plate 12 on the top of the second jig 8 can be disassembled by bolts, and different jigs can be quickly replaced when one of the jigs is heated and pressurized, which can improve the adaptability of the jig and further improve the production efficiency of the magnetic group 9.
