[0002] In the motor manufacturing process, the glue dispensing process of the motor core is a key step to ensure the firmness of the core laminations. The quantitative glue dispensing device used for the motor core ensures the bonding strength between the core laminations by precisely controlling the amount of glue used and the dispensing position, thereby improving the overall performance and service life of the motor.

[0003] The existing technology has the following problems:

[0004] Traditional dispensing devices often leave adhesive residue on the nozzle after dispensing. If not cleaned in time, the residue will solidify and clog the nozzle, affecting the accuracy of subsequent dispensing and even damaging the nozzle, thus increasing maintenance costs. Utility Model Content

[0005] This invention provides a quantitative dispensing device for motor cores to solve the problem mentioned in the background art that residual glue easily clogs the nozzle and affects the subsequent dispensing accuracy.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A quantitative dispensing device for motor cores includes a worktable. Two mounting brackets are fixedly connected to the outer side of the worktable. A mounting shell is fixedly connected to the top of the mounting brackets. A first motor is fixedly connected to the outer side of the mounting shell. A threaded rod is fixedly connected to the output end of the first motor. A threaded block is threadedly connected to the outer circumference of the threaded rod. An electric push rod is fixedly connected to the bottom of the threaded block. A dispensing nozzle is fixedly connected to the output end of the electric push rod. An input pipe is fixedly connected to the outer side of the dispensing nozzle. A wiping mechanism is provided on the outer side of the mounting brackets. A shaking mechanism is provided inside the worktable.

[0008] The wiping mechanism includes a motor base and two fixed blocks. The outer side of the motor base is fixedly connected to the outer side of the mounting frame. A second motor is fixedly connected to the outer side of the motor base. A turntable is fixedly connected to the output end of the second motor. An eccentric shaft is fixedly connected to the outer edge of the turntable. A movable frame is slidably connected to the outer side of the eccentric shaft. A connecting shaft is fixedly connected to the bottom of the movable frame. A mounting block is rotatably connected to the bottom of the connecting shaft. A rotating shaft is rotatably connected inside the mounting block. A cleaning block is fixedly connected to the outer side of the mounting block. The outer sides of both fixed blocks are fixedly connected to the outer side of the mounting frame. A support rod is fixedly connected between the fixed blocks.

[0009] The shaking mechanism includes a mounting slot, a third motor is fixedly connected inside the mounting slot, a half gear is fixedly connected to the output end of the third motor, a rotating shaft is rotatably connected inside the mounting slot, a gear is fixedly connected to the outer circumference of the rotating shaft, a spring is fixedly connected to the outer circumference of the rotating shaft, a connecting block is fixedly connected to the end of the spring away from the rotating shaft, and a rotating block is fixedly connected to the top of the rotating shaft.

[0010] Preferably, both ends of the threaded rod are rotatably connected inside the mounting housing, and the outer side of the threaded block is slidably connected inside the mounting housing.

[0011] Preferably, the inside of the movable frame is slidably connected to the outer periphery of the support rod, and the outside of the movable frame is slidably connected to the outside of the mounting bracket.

[0012] Preferably, the two ends of the rotating shaft are fixedly connected inside the mounting frame, and the outer side of the mounting block is rotatably connected inside the mounting frame.

[0015] Preferably, the outer side of the connecting block is fixedly connected to the inside of the mounting groove, and the outer side of the rotating block is rotatably connected to the top of the worktable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model provides a quantitative dispensing device for motor cores. The wiping mechanism is driven by a second motor to rotate the turntable and eccentric shaft, which in turn drives the moving frame to slide back and forth along the support rod. The connecting shaft pushes the mounting block to rotate around the rotating shaft, so that the cleaning block is in close contact with the dispensing nozzle and wipes back and forth, thus removing residual glue from the nozzle in time, avoiding blockage, ensuring accurate and stable dispensing in the future, and reducing maintenance costs.

[0018] 2. This utility model provides a quantitative dispensing device for motor iron cores. The shaking mechanism drives the half gear to rotate through a third motor. The meshing gear drives the rotating shaft to rotate. The spring stores energy. After the half gear disengages, the spring resets and causes the rotating shaft to rotate in the opposite direction. This enables the rotating block to drive the motor iron core to rotate back and forth in a small amplitude. This allows the glue to adhere to the motor iron core quickly and evenly after dispensing, thus improving dispensing efficiency. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-6 As shown, a quantitative dispensing device for motor cores includes a workbench 1. Two mounting brackets 2 are fixedly connected to the outside of the workbench 1. A mounting shell 3 is fixedly connected to the top of the mounting bracket 2. A first motor 4 is fixedly connected to the outside of the mounting shell 3. A threaded rod 5 is fixedly connected to the output end of the first motor 4. A threaded block 6 is threadedly connected to the outer circumference of the threaded rod 5. An electric push rod 7 is fixedly connected to the bottom of the threaded block 6. A dispensing nozzle 8 is fixedly connected to the output end of the electric push rod 7. An input pipe 9 is fixedly connected to the outside of the dispensing nozzle 8. A wiping mechanism 10 is provided on the outside of the mounting bracket 2. A shaking mechanism 11 is provided inside the workbench 1.

[0028] The wiping mechanism 10 includes a motor base 100 and two fixing blocks 109. The outer side of the motor base 100 is fixedly connected to the outer side of the mounting frame 2. A second motor 101 is fixedly connected to the outer side of the motor base 100. A turntable 102 is fixedly connected to the output end of the second motor 101. An eccentric shaft 103 is fixedly connected to the outer edge of the turntable 102. A movable frame 104 is slidably connected to the outer side of the eccentric shaft 103. A connecting shaft 105 is fixedly connected to the bottom of the movable frame 104. A mounting block 106 is rotatably connected to the bottom of the connecting shaft 105. A rotating shaft 107 is rotatably connected inside the mounting block 106. A cleaning block 108 is fixedly connected to the outer side of the mounting block 106. The outer sides of both fixing blocks 109 are fixedly connected to the outer side of the mounting frame 2. A support rod 1010 is fixedly connected between the fixing blocks 109.

[0029] It should be noted that after the dispensing is completed, the second motor 101 is started, the turntable 102 drives the eccentric shaft 103 to rotate, the moving frame 104 slides back and forth along the support rod 1010, and the connecting shaft 105 pushes the mounting block 106 to rotate around the rotating shaft 107, so that the cleaning block 108 makes close contact with the surface of the dispensing nozzle 8 and wipes it back and forth to remove residual glue. After wiping, the second motor 101 is turned off, and the cleaning block 108 returns to its original position with the mechanism, without affecting the normal operation of the dispensing nozzle 8.

[0030] The wobbling mechanism 11 includes a mounting groove 110, a third motor 111 fixedly connected inside the mounting groove 110, a half gear 112 fixedly connected to the output end of the third motor 111, a rotating shaft 113 rotatably connected inside the mounting groove 110, a gear 114 fixedly connected to the outer periphery of the rotating shaft 113, a spring 115 fixedly connected to the outer periphery of the rotating shaft 113, a connecting block 116 fixedly connected to the end of the spring 115 away from the rotating shaft 113, and a rotating block 117 fixedly connected to the top of the rotating shaft 113.

[0031] It should be noted that when the motor core is placed on the rotating block 117 and the third motor 111 is started, the half gear 112 rotates and meshes with the gear 114, driving the rotating shaft 113 to rotate. The spring 115 is twisted and stores energy. When the half gear 112 disengages from the gear 114, the spring 115 resets and drives the rotating shaft 113 to rotate in the opposite direction, causing the rotating block 117 to drive the core to rotate back and forth in a small amplitude, so that the glue can be quickly and evenly applied to the core, improving the glue application efficiency.

[0032] like Figure 2 As shown, both ends of the threaded rod 5 are rotatably connected inside the mounting shell 3, and the outer side of the threaded block 6 is slidably connected inside the mounting shell 3.

[0033] It should be noted that the stable rotation of the threaded rod 5 within the mounting housing 3 ensures the smoothness of the threaded transmission, and the sliding of the threaded block 6 along the mounting housing 3 can precisely control the lateral movement trajectory of the dispensing nozzle 8, ensuring accurate dispensing position.

[0034] like Figure 4 As shown, the movable frame 104 is slidably connected to the outer periphery of the support rod 1010 inside, and slidably connected to the outer side of the mounting bracket 2 outside.

[0035] It should be noted that the support rod 1010 provides guidance for the moving frame 104, ensuring its stable reciprocating sliding. The sliding cooperation between the moving frame 104 and the mounting bracket 2 further enhances the structural stability of the wiping mechanism.

[0036] like Figure 3 As shown, the two ends of the rotating shaft 107 are fixedly connected to the inside of the mounting bracket 2, and the outer side of the mounting block 106 is rotatably connected to the inside of the mounting bracket 2.

[0037] It should be noted that the rotating shaft 107 is fixed inside the mounting bracket 2, providing a fulcrum for the rotation of the mounting block 106, so that the cleaning block 108 can flexibly fit the surface of the dispensing nozzle 8 and improve the wiping effect.

[0038] like Figure 1 As shown, the cleaning block 108 and the dispensing nozzle 8 are in contact.

[0039] It should be noted that the contact between the two ensures that the cleaning block 108 effectively wipes the surface of the nozzle, ensuring that residual glue is completely removed and preventing nozzle clogging.

[0040] like Figure 6 As shown, half gear 112 and gear 114 mesh with each other, and the outer circumference of rotating shaft 113 is rotatably connected to the inside of worktable 1.

[0041] It should be noted that the intermittent meshing of the half gear 112 and the gear 114 enables the reciprocating rotation of the rotating shaft 113, and the rotational connection of the rotating shaft 113 within the worktable 1 ensures the stability of the wobbling mechanism 11 during operation.

[0042] like Figure 2 , Figure 6 As shown, the outer side of the connecting block 116 is fixedly connected to the inside of the mounting groove 110, and the outer side of the rotating block 117 is rotatably connected to the top of the worktable 1.

[0043] It should be noted that the connecting block 116 fixes one end of the spring 115 so that it can store force when the rotating shaft 113 rotates. The rotation of the rotating block 117 on the top of the worktable 1 can drive the iron core to rotate, so that the glue can be applied quickly and evenly.

[0044] The working principle of this utility model is as follows: When in use, the motor core is placed on the rotating block 117, and glue is supplied to the dispensing nozzle 8 through the input pipe 9. The first motor 4 is started, and the threaded rod 5 drives the threaded block 6 to move laterally. The horizontal position of the dispensing nozzle 8 is adjusted, and the electric push rod 7 extends and retracts to adjust the height of the nozzle. After aligning with the dispensing position of the core, a quantitative amount of glue is dispensed. After the dispensing is completed, the dispensing nozzle 8 is turned off, and the wiping mechanism 10 is started. The second motor 101 drives the cleaning block 108 to wipe the nozzle surface back and forth to remove residual glue. The shaking mechanism 11 is started, and the third motor 111 drives the rotating block 117 to rotate the core back and forth, so that the glue is quickly and evenly attached to the core.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
