Technical Field

[0001] The utility model relates to the technical field of magnet assembly, in particular to a device for automatic gluing and lamination of magnets. Background Art

[0002] Semi-finished NdFeB is the black sheet product of NdFeB before electroplating. The NdFeB black sheet is bonded and then machined and electroplated. Compared with ordinary conventional products, it is more widely used. The existing semi-finished black sheet magnet bonding usually adopts manual application of glue, and then the magnets are stacked up one by one manually after applying glue. This glue-applying and laminating method has the following problems:

[0003] 1. Currently, most of the glue used for bonding semi-finished black sheets is epoxy structural glue. Manual application of this type of glue will result in uneven glue application, agitation of the glue, and the generation of a large number of bubbles.

[0004] 2. Manually applying glue cannot ensure uniform application of glue, thus causing serious waste of glue.

[0005] 3. After the magnets are coated with glue, they are stacked up manually one by one. In this process, there is a risk of rubbing off the glue, which will affect the structural stability of the magnet assembly.

[0006] 4. The manual glue application and lamination process is inefficient and cannot meet the needs of large-scale production. Utility Model Content

[0034] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The utility model provides a device for automatically applying glue and laminating magnets, such as Figures 1 to 5 As shown, it includes a workbench 1 and a loading station 2, a gluing station 3, a laminating station 4 and a moving platform 7 arranged on the workbench 1. The equipment can realize automatic gluing and automatic laminating of magnets.

[0036] like Figure 1 and 5As shown, the design of the mobile platform 7 is a key part to ensure that the magnets can be efficiently and accurately transferred between the various stations. The platform is located between the loading station 2, the gluing station 3 and the lamination station 4, and makes linear reciprocating motion between these stations, thereby realizing the transmission of magnets between different stations. The mobile platform 7 is located between the above-mentioned stations, and a platform moving motor 72 is provided at the end of the mobile platform 7, and the platform moving motor 72 drives the mobile platform 7 to make linear reciprocating motion between the stations. A platform moving motor 72 is provided at the end of the mobile platform 7, which is the core component that drives the movement of the mobile platform 7. The platform moving motor 72 usually adopts a servo motor or a stepper motor, which has the characteristics of high precision, high stability and strong controllability. By controlling the rotation of the motor, the movement speed and position of the mobile platform 7 can be accurately controlled, thereby ensuring that the magnet can accurately reach each station.

[0037] At least four grooves 71 for placing magnets are provided on the mobile platform 7. The size and shape of these grooves 71 match the magnets to ensure the stability and safety of the magnets during the transmission process. When the mobile platform 7 is translated along the setting direction of the workstation, the grooves 71 will correspond to different workstations respectively. For example, when the groove 71 is located at the loading station 2, the magnet can be placed in the groove 71 through the loading mechanism; when the groove 71 moves to the glue-spreading station 3, the glue-spreading mechanism will apply glue to the magnet in the groove 71; when the groove 71 reaches the stacking station 4, the stacking mechanism will take out the magnet in the groove 71 and stack it.

[0038] The loading station 2 is used to transfer the stored magnets to the designated groove 71 on the workbench 1, so as to facilitate the subsequent gluing and lamination process of the magnets. Figure 2 and Figure 3 As shown, the feeding station 2 uses a vibrating plate to feed the magnets. In addition, other feeding mechanisms such as a conveyor belt and a pneumatic push rod can also be used.

[0039] Key References Figure 1 and Figure 2 The glue spreading station 3 is used to apply glue to the magnets on the workbench 1. The glue spreading station 3 includes a glue spreading gantry frame 31 located above the mobile platform 7, and the glue spreading gantry frame 31 is provided with a glue spreading X-axis moving motor 32, a glue spreading Y-axis moving motor 33 and a glue discharging cylinder 34. The glue spreading Y-axis moving motor 33 is mounted on the glue spreading X-axis moving motor 32, and the glue discharging cylinder 34 is mounted on the glue spreading Y-axis moving motor 33. The glue spreading position is controlled by two groups of servo motors. The glue discharging cylinder 34 is provided with a group of glue spreading motors 35 for controlling the glue spreading. In addition, a customized glue nozzle 36 is added to the glue discharging position of the glue discharging cylinder 34 to control the glue discharging amount and the uniformity of the glue.

[0040] The entire working process of the glue spreading station 3 is as follows: when the mobile platform 7 moves the magnet to the glue spreading station 3, the glue spreading X-axis moving motor 32 and the glue spreading Y-axis moving motor 33 will work together to move the glue dispensing cylinder 34 to the top of the magnet. Then, the glue dispensing motor 35 will control the glue to flow out of the glue nozzle 36 and evenly spread it on the magnet. By accurately controlling the movement of the servo motor and the glue dispensing amount of the glue nozzle 36, it can be ensured that each magnet can be evenly and appropriately coated with glue.

[0041] The stacking station 4 is used to stack the magnets after applying glue. Figure 4 The stacking station 4 includes a stacking gantry frame 41, on which a grabbing X-axis moving motor 42, a grabbing Y-axis moving motor 43 and a grabbing clamp 44 are provided. The grabbing Y-axis moving motor 43 is mounted on the grabbing X-axis moving motor 42 and moves along the grabbing X-axis moving motor 42. The grabbing clamp 44 is mounted on the grabbing Y-axis moving motor 43, and the position of the grabbing clamp 44 is controlled by two sets of servo motors. The grabbing clamp 44 is provided with a grabbing cylinder 45, which is used to control the grabbing clamp 44 to grasp or release the magnet.

[0042] Key References Figure 1 and Figure 3 The stacking station 4 further includes a lifting mechanism and a pushing mechanism to assist the gripping jaws 44 in performing the magnet stacking operation. The lifting mechanism in this embodiment is a lifting cylinder 6, and the pushing mechanism is a pushing motor 5. The lifting cylinder 6 is located below the moving platform 7 and is used to lift the magnet in the groove 71. The pushing motor 5 is located on one side of the groove 71 and is used to push the magnet in the groove 71 toward the lifting mechanism.

[0043] In order to optimize the unloading process and ensure that the magnets can be accurately and efficiently placed in the jig of the next process, the design of the gripper 44 does need to take its rotation function into account. Figure 4 As shown, a rotary cylinder 46 is also provided on the gripper 44 to drive the gripper 44 to rotate. The addition of the rotary cylinder 46 enables the gripper 44 to perform a rotating action. Each time the magnets are stacked, the gripper 44 is driven by the rotary cylinder 46 and the gripper X and Y axis moving motors to place them in the next process jig, and then the gripper starts to grip again.

[0044] The working process of the device for automatic gluing and lamination of magnets in the utility model is as follows:

[0045] like Figure 1As shown, the magnets are fed through the vibration plate and orderly enter the first groove 71 of the mobile platform 7 for receiving materials. When the first groove 71 is full of magnets, the mobile platform 7 starts to move. When the magnets in the first groove 71 reach the glue applying position, the glue applying station 3 starts to apply glue to the magnets in the first groove 71, and the second groove 71 starts to be fed through the vibration plate. When the magnets in the first groove 71 are completely glued and the second groove 71 is full of magnets, the mobile platform 7 will continue to move. When the first groove 71 reaches the stacking position, the stacking station 4 starts to stack the magnets in the first groove 71.

[0046] The stacking process is as follows: the lifting cylinder 6 lifts up a magnet, the grabbing claw 44 is used to grab a magnet after the X and Y axis moving motors are positioned, and then the pushing motor 5 pushes the second magnet to the position of the lifting cylinder 6. At this time, the grabbing claw 44 puts the first magnet on the second magnet, and finally the lifting cylinder 6 lifts up the two magnets again, and then the grabbing claw 44 grabs again, and so on to complete the magnet stacking after the glue is applied.

[0047] After the first groove 71 is stacked, the mobile platform 7 continues to move, and the mobile platform 7 completes the magnetization and glue application work at the corresponding position of the subsequent groove. After all four grooves 71 are stacked, the equipment completes one work.

[0048] Each time the stacked magnets are placed in the next process fixture by the material grabbing claw 44 under the drive of the rotating cylinder 46 and the X and Y axis moving motors of the material grabbing, and then the material grabbing is restarted.

[0049] It should be noted that the utility model is mainly used for the automatic gluing and lamination of magnets for gluing and lamination of semi-finished NdFeB magnets. This type of magnetic assembly is composed of multiple pieces of semi-finished NdFeB arranged and bonded together, and then machined into the final finished assembly. However, the utility model is universal and is not limited to semi-finished NdFeB magnets, but is also suitable for the processing of other types of magnet assemblies.
