Description

Technical Field

[0001] This invention relates to the field of motor processing technology, specifically to a stator vacuum potting device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors and generators. During the manufacturing process of an electric motor, the stator windings installed inside the motor housing need to be potted with glue. After the potting glue cures, it forms a protective layer, which plays a role in waterproofing, moisture-proofing, dustproofing, insulation, heat dissipation, and shock absorption, thereby improving the electrical insulation performance of the windings and electronic components.

[0003] Existing potting processes include two types: "vacuuming before potting" and "potting before vacuuming." "Vacuuming before potting" is currently the mainstream process, offering better air bubble removal and process controllability than the latter. Vacuum potting equipment using this process has high production efficiency when potting and sealing small-volume items such as capacitors and chips. However, this type of equipment has limited processing space and is often used for potting small-volume items such as capacitors and chips or a small number of motors. For larger motors, it can only pot one unit at a time. The "potting before vacuuming" process is more suitable for potting large-size stators and stators with porous / layered structures. However, the disadvantage of this process is that the injected glue can block the air venting channels, making it difficult to completely remove deep air bubbles during subsequent vacuuming. This can easily lead to uneven filling or localized glue shortages, which restricts the development of this process.

[0004] Therefore, there is an urgent need for a vacuum dispensing equipment that can solve the problems of deep air bubble removal, uneven glue filling, and local glue shortage, and adopt the "glue first, vacuum later" process to meet the special stator dispensing requirements of this process and improve the dispensing and sealing quality. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a stator vacuum potting device.

[0006] To solve the above technical problems, the technical solution provided by the present invention is: a stator vacuum potting device, including an outer frame mechanism, an exhaust mechanism and a material rack. The outer frame mechanism includes a support frame and a conveying mechanism. The exhaust mechanism includes a treatment tank and a sealing cover. The conveying mechanism cooperates with the sealing cover to move the material rack into the treatment tank. The top of the sealing cover is provided with a hydraulic cylinder fixed on the support frame. The hydraulic cylinder pushes the sealing cover to press against the top of the treatment tank.

[0007] The material rack includes a frame with multiple material cylinders rotatably mounted on it. A tray is rotatably mounted at the bottom of each material cylinder, and a motor is placed on the tray. A dispensing mechanism is located outside the treatment tank. The dispensing mechanism dispenses adhesive to the motor on the material rack inside the treatment tank. After dispensing, a sealing cap is pressed onto the treatment tank and a vacuum is drawn inside the treatment tank. A drive mechanism is located inside the sealing cap. The drive mechanism drives the dispensed motor to rotate inside the material cylinder, so that the adhesive inside the motor is evenly distributed. A swing drive mechanism is located on the treatment tank. The swing drive mechanism is used to push the horizontal swing frame to swing laterally, so that the material cylinder rotates and swings, accelerating the removal of air bubbles.

[0008] As an improvement: multiple material cylinders are arranged in a longitudinal and transverse manner on the frame, and the rotating shafts at both ends of the same row of material cylinders are connected to each other. A gear is connected to the rotating shaft of the outer material cylinder in the same row. A horizontal swing frame is provided on the outer side of the frame. Fixed slides that slide with the horizontal swing frame are provided on both sides of the frame. A rack that meshes with the gear is provided at one of the gears on the horizontal swing frame. A collision beam is provided on both sides of each row of material cylinders on the frame.

[0009] As an improvement: the swing drive mechanism includes a motor, a drive shaft, a transmission shaft, a push mechanism, and a synchronous shaft. The transmission shaft and the push mechanism are provided on both sides of the treatment pool. The output end of the motor is provided with a gear 2. The drive shaft is provided with a gear 3 that meshes with the gear 2. The two ends of the drive shaft are provided with gear 4. The transmission shaft is provided with a gear 5 that meshes with the gear 4. One end of the transmission shaft drives the push mechanism to perform a pushing action, and the other end is provided with a bevel gear 1. Both ends of the synchronous shaft are provided with bevel gear 2 that meshes with the bevel gear 1.

[0010] As an improvement: the pushing mechanism includes a push cylinder, a push column, and a transmission rod. The treatment pool has sliding cavities on both sides that slide with the push cylinder. The push column slides with the sliding groove on the rear side of the push cylinder. The push cylinder has a spring connected to the push column. One end of the transmission shaft has a turntable with an eccentric shaft on it. One end of the transmission rod is hinged to the push column, and the other end rotates with the eccentric shaft. The eccentric shafts on both sides of the treatment pool are located on the same side of the turntable.

[0011] As an improvement: the sealing cover is provided with multiple displacement mechanisms, each of which includes a hydraulic cylinder and a lifting arm. The hydraulic cylinder is fixed to the sealing cover and drives the lifting arm to move up and down. The frame is provided with a hook, which is hung on the lifting arm. The bottom of the sealing cover is provided with an isolation plate, and the isolation plate is provided with a drive mechanism. The displacement mechanism causes the drive mechanism and the tray to clamp the motor, and the drive mechanism causes the motor to rotate.

[0012] As an improvement: the rotary drive mechanism includes a second motor and multiple drive groups. Each drive group includes a transmission component and multiple drive components. The second motor drives the drive components to rotate through the transmission component. Each drive component includes a pressure plate that is rotatably disposed at the bottom of the isolation plate. The pressure plate is in contact with the top of the motor.

[0013] As an improvement: the dispensing mechanism includes a fixed frame on both sides of the treatment pool, a walking device is movably mounted on the fixed frame, a crossbeam is connected to the top of the two walking devices, a horizontal moving platform is movably mounted on the crossbeam, a lifting platform is raised and lowered on the horizontal moving platform, and a dispensing device is mounted on the lifting platform to inject the dispensing glue into the motor.

[0014] The advantages of this invention compared to existing technologies are as follows: This device realizes the glue-filling process of the motor stator. Through the material rack design and the coordination of the swing drive mechanism, the motor swings and vibrates during the glue-filling process, thereby allowing air bubbles on the negative side and those attached to the surface to be expelled, improving the sealing effect of the potting compound. Specifically:

[0015] 1. Through the design of the material rack and the cooperation of the swing drive mechanism, the angle of the material cylinder is adjusted so that the air bubbles inside the motor that are blocked from rising can be discharged. The material cylinder collides and vibrates with the impact beam, thereby expelling the tiny air bubbles on the motor.

[0016] 2. After the material rack is lifted by the displacement mechanism, the rotary drive mechanism cooperates with the motor on the material rack to make multiple motors rotate, so that the potting glue inside the motor is evenly distributed after the glue is poured, avoiding local accumulation or gaps.

[0017] 3. By using the sealing cover to transfer the material rack, in conjunction with the glue dispensing mechanism, the transfer, dispensing, and defoaming of the motor stator glue dispensing are integrated and automated, reducing the motor transfer process and improving glue dispensing efficiency and quality.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 5As shown, a stator vacuum dispensing device includes an outer frame mechanism 1, an exhaust mechanism 2, and a material rack 3. The outer frame mechanism 1 includes a support frame 11, on which a conveying mechanism 12 is mounted. The exhaust mechanism 2 includes a treatment tank 4 and a sealing cover 5. The conveying mechanism 12 moves the material rack 3 to below the sealing cover 5 and hangs the material rack 3 at the bottom of the sealing cover 5. A hydraulic cylinder 51 fixed to the support frame 11 is mounted on the top of the sealing cover 5. The hydraulic cylinder 51 pushes the sealing cover 5 to press it against the top of the treatment tank 4. The material rack 3 includes a frame body 31, on which multiple material cylinders 32 are rotatably mounted. A tray 321 is rotatably mounted at the bottom of each material cylinder 32. A motor is placed on the tray 321. A dispensing mechanism 8 is located outside the treatment tank 4. The glue-filling mechanism 8 performs glue-filling treatment on the motor on the material rack 3 inside the treatment tank 4. After glue-filling, the sealing cover 5 is pressed on the treatment tank 4 and the inside of the treatment tank 4 is evacuated. The sealing cover 5 is equipped with a rotary drive mechanism 7, which drives the glue-filled motor to rotate inside the material cylinder 32, so that the glue liquid inside the motor is evenly distributed. The treatment tank 4 is equipped with a swing drive mechanism 6, which is used to push the horizontal swing frame 33 to swing laterally, so that the material cylinder 32 rotates and swings, accelerating the removal of air bubbles. The treatment tank 4 is equipped with a stretcher 41 for placing the material rack 3. The top of the treatment tank 4 and the bottom of the sealing cover 5 are both equipped with sealing rings 44. The treatment tank 4 is equipped with a vacuum pipe connector 45, which is connected to an external vacuuming device.

[0033] This stator vacuum potting device mainly solves problems such as uneven glue distribution, difficulty in completely removing air bubbles, low potting efficiency, and insufficient sealing affecting the vacuum effect during motor potting. Its working principle revolves around the coordinated operation of various mechanisms: First, the conveying mechanism 12 of the outer frame mechanism 1 moves the material rack 3 carrying the motor to the bottom of the sealing cover 5 and hangs the material rack 3 at the bottom of the sealing cover 5. At this time, the multiple material cylinders 32 on the material rack 3 are kept stable by the frame 31, and the motor is placed on the tray 321 at the bottom of the material cylinder 32. Then the sealing cover 5 is lowered and the material rack 3 is placed on the stretcher 41. When potting is required, the potting mechanism 8 performs potting treatment on the motor on the material rack 3 inside the treatment tank 4 to ensure that the glue is accurately injected into the motor stator.

[0034] After the glue is applied, the hydraulic cylinder 51 on the support frame 11 pushes the sealing cover 5 downwards, pressing it tightly against the top of the treatment tank 4. The sealing rings 44 at the top of the treatment tank 4 and the bottom of the sealing cover 5 work together to ensure a good sealing environment inside the treatment tank 4. Subsequently, the vacuum pipe connector 45 on the treatment tank 4 is connected to a vacuum pumping device to perform a vacuum pumping operation inside the treatment tank 4, using the vacuum environment to promote the removal of air bubbles from the motor.

[0035] During this process, the rotating drive mechanism 7 inside the sealing cover 5 drives the motor after dispensing to rotate inside the material cylinder 32, so that the glue is evenly distributed inside the motor and avoids local accumulation or gaps; at the same time, the swing drive mechanism 6 on the treatment tank 4 pushes the horizontal swing frame 33 to swing laterally, driving the material cylinder 32 to rotate and swing, further accelerating the rise and removal of air bubbles in the glue and improving the dispensing quality.

[0036] Combined with appendix Figure 3 and attached Figure 4 As shown, the material rack 3 includes a frame 31, on which multiple material cylinders 32 are rotatably mounted. A motor is placed inside the material cylinder 32. A tray 321 is rotatably mounted at the bottom of the material cylinder 32. The tray 321 has a slot 322. The multiple material cylinders 32 are arranged longitudinally and transversely on the frame 31. The rotating shafts at both ends of the same row of material cylinders 32 are connected to each other. A gear 34 is connected to the rotating shaft of the outer material cylinder 32 in the same row. A horizontal swing frame 33 is provided on the outer side of the frame 31. Fixed slides 314 that slide with the horizontal swing frame 33 are provided on both sides of the frame 31. A rack 332 that meshes with the gear 34 is provided at the gear 34 in the horizontal swing frame 33. A bumper beam 313 is provided on both sides of each row of material cylinders 32 in the frame 31.

[0037] Material rack 3 mainly solves the problems of unstable placement and easy displacement of motors during potting and subsequent processing, difficulty in achieving synchronous and stable rotation and oscillation of multiple material cylinders 32, and lack of effective limit during oscillation leading to chaotic operation. The working principle of material rack 3 is as follows: the motor is placed in a protective cover (not shown), which can prevent potting glue from flowing onto the motor housing. Then, multiple motors are placed in the material cylinders 32 and inserted into the slots 322 through the card platform at the bottom of the protective cover. The tray 321 allows the motor to rotate inside the material cylinders 32.

[0038] During glue dispensing, the material rack 3 is placed on the stretcher 41, and glue is dispensed through the glue dispensing mechanism 8. After glue dispensing, the sealing cover 5 is closed, and multiple motors are rotated through the drive mechanism 7 to disperse the potting glue inside the motors evenly. Then, a vacuum process is performed. After vacuuming, the swing drive mechanism 6 pushes the horizontal swing frame 33 to swing laterally. Through the meshing transmission between the rack 332 and the gear 34, the gear 34 rotates, thereby driving a row of material cylinders 32 to rotate. This allows the material cylinders 32 to adjust their angle, so that the air bubbles inside the motor that are blocked from rising can be discharged. After the material cylinders 32 hit the impact beam 313, the motors in the material cylinders 32 vibrate, thereby discharging the tiny air bubbles on the motors.

[0039] Combined with appendix Figure 2 Appendix Figure 5 Appendix Figure 7 and attached Figure 8As shown, the swing drive mechanism 6 includes a motor 61, a drive shaft 62, a transmission shaft 63, a pushing mechanism 64, and a synchronous shaft 65. The processing pool 4 has transmission shafts 63 and pushing mechanisms 64 on both sides. The processing pool 4 has a support platform 43 that rotatably engages with the drive shaft 62, transmission shaft 63, and synchronous shaft 65. The processing pool 4 has a housing outside the swing drive mechanism 6, as shown... Figure 2 The outer shell is Figure 5 Hidden within, the motor 61 has a gear 611 at its output end, a gear 621 on the drive shaft 62 that meshes with the gear 611, a gear 622 at both ends of the drive shaft 62, a gear 632 on the transmission shaft 63 that meshes with the gear 622, a drive mechanism 64 at one end of the transmission shaft 63 to perform a pushing action, and a bevel gear 631 at the other end, and a bevel gear 651 at both ends of the synchronous shaft 65 that meshes with the bevel gear 631.

[0040] Combined with appendix Figure 5 Appendix Figure 7 and attached Figure 8 As shown, the pushing mechanism 64 includes a push cylinder 641, a push column 642, and a transmission rod 643. The treatment pool 4 has sliding cavities 42 on both sides that slide with the push cylinder 641. The horizontal frame 33 has a receiving plate 331 that matches the end of the push cylinder 641. The push column 642 slides with the rear sliding groove of the push cylinder 641. The push cylinder 641 has a spring 644 connected to the push column 642. One end of the transmission shaft 63 has a turntable 633. The turntable 633 has an eccentric shaft 634. One end of the transmission rod 643 is hinged to the push column 642, and the other end is rotatably connected to the eccentric shaft 634. The eccentric shafts 634 on both sides of the treatment pool 4 are located on the same side of the turntable 633.

[0041] The swing drive mechanism 6 mainly solves the problems of unstable swing caused by asynchronous transmission of driving force on both sides during the horizontal swing of the material rack 3, easy loss or jamming of power transmission between multiple axes, and lack of protection during operation, which makes it susceptible to interference from the external environment. Its working principle is based on the coordinated transmission of each component: the motor 61 serves as the power source, and the gear 611 at its output end meshes with the gear 621 on the drive shaft 62. When the motor 61 starts, it drives the drive shaft 62 to rotate through gear meshing. The support platform 43 on the processing pool 4 provides stable rotational support for the drive shaft 62.

[0042] The gears 622 at both ends of the drive shaft 62 mesh with the gears 632 on the transmission shaft 63, transmitting power to the transmission shafts 63 on both sides of the treatment tank 4, causing the two transmission shafts 63 to rotate synchronously. One end of the transmission shaft 63 drives the push mechanism 64 to push, thereby causing the horizontal swing frame of the material rack to swing laterally; the bevel gear 631 at the other end meshes with the bevel gear 651 at both ends of the synchronous shaft 65. With the transmission action of the bevel gear, the synchronous shaft 65 and the two transmission shafts 63 on both sides are kept linked, further ensuring the consistency of power transmission on both sides and avoiding swaying due to inconsistent driving forces on both sides. At the same time, the outer shell of the treatment tank 4 on the outside of the swing drive mechanism 6 ( Figure 5 The hidden section can protect internal gears, shafts and other components, reducing the impact of external dust and impurities on the operation of the mechanism. The support platform 43 also provides stable rotational support for the transmission shaft 63 and the synchronous shaft 65, ensuring that the entire swing drive mechanism 6 provides power for the horizontal swing of the material rack efficiently and stably.

[0043] When the drive shaft 63 rotates, the turntable 633 at one end rotates synchronously with the drive shaft 63. The eccentric shaft 634 on the turntable 633 performs eccentric circular motion, which is transmitted to the push column 642 through the drive rod 643. The push column 642 slides in conjunction with the slide groove on the rear side of the push cylinder 641 and moves back and forth along the slide groove under the drive of the drive rod 643. At the same time, the spring 644 in the push cylinder 641 is connected to the push column 642, which drives the push cylinder 641 to slide in the slide cavities 42 on both sides of the treatment pool 4. As the push column 642 moves back and forth, the push cylinder 641 is pushed, and its end cooperates with the receiving plate 331 on the horizontal swing frame 33 to push the horizontal swing frame 33.

[0044] Since the eccentric shafts 634 on both sides of the treatment pool 4 are set on the same side of the turntable 633, the action of the two pushing mechanisms 64 is synchronized, avoiding uneven force on the horizontal frame 33 and causing it to tilt, and realizing the reciprocating swing of the material rack 3. The spring 644 has a buffering capacity when the push column 642 pushes, preventing the push cylinder 641 from being damaged when it collides with the receiving plate 331.

[0045] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 6 As shown, the sealing cover 5 is provided with multiple displacement mechanisms 53. The displacement mechanism 53 includes a second hydraulic cylinder 531 and a lifting arm 532. The second hydraulic cylinder 531 is fixed on the sealing cover 5 and drives the lifting arm 532 to move up and down. The frame 31 is provided with a second hook 312, which is hung on the lifting arm 532. The bottom of the sealing cover 5 is provided with an isolation plate 52, and the isolation plate 52 is provided with a rotary drive mechanism 7. The displacement mechanism 53 causes the rotary drive mechanism 7 and the tray 321 to clamp the motor, and the rotary drive mechanism 7 causes the motor to rotate.

[0046] Working principle of sealing cover 5 and displacement mechanism 53: During the feeding stage, hydraulic cylinder 1 51 drives sealing cover 5 to rise to the top, and hydraulic cylinder 2 531 drives lifting arm 532 to move to a suitable height. Then, through the cooperation of conveying mechanism 12 and displacement mechanism 53, hook 2 312 of material rack 3 is hung on lifting arm 532. Then, conveying mechanism 12 moves out, hydraulic cylinder 1 51 pushes sealing cover 5 to press on treatment tank 4, and hydraulic cylinder 2 531 drives lifting arm 532 to place material rack 3 on stretcher 41 for glue filling and venting. After glue filling is completed, hydraulic cylinder 2 531 drives lifting arm 532 to rise, so that material rack 3 drives motor to rise, so that the top of motor contacts pressure plate 742. Through rotation drive mechanism 7, the motor on material rack 3 is rotated, thereby distributing the glue in motor evenly.

[0047] Combined with appendix Figure 1 and attached Figure 3 As shown, the conveying mechanism 12 includes a conveying frame 13, which is fixed on the support frame 11 on both sides of the exhaust mechanism 2. The conveying frame 13 is provided with a transversely movable transport platform 14, and a carrying pole 15 is provided on the transport platform 14. The frame 31 is provided with a hook 311, which is located inside the hook 312. The material rack 3 is hung on the carrying pole 15 through the hook 311 and is conveyed by the conveying mechanism 12.

[0048] Working principle of conveying mechanism 12: Conveying mechanism 12 is existing technology. Its function is to convey the material rack 3 and hang the material rack 3 on the lifting arm 532. During conveying, the material rack 3 is hung on the support pole 15 through hook 1 311. After the material rack 3 moves with the transport platform 14 to below the sealing cover 5, the hydraulic cylinder 2 531 drives the lifting arm 532 to hang the hook 2 312 of the material rack 3 on the lifting arm 532 and make hook 1 311 disengage from the support pole 15, so as to realize the transfer of the material rack 3.

[0049] Combined with appendix Figure 6 Appendix Figure 9 Appendix Figure 10 and attached Figure 11As shown, the drive mechanism 7 includes a second motor 71 and multiple drive groups 72. Each drive group 72 includes a transmission component 73 and four drive components 74. The transmission component 73 includes a second sprocket 731 and a sixth gear 732 coaxially connected. Each drive component 74 includes a seventh gear 741 and a pressure plate 742 coaxially connected. The pressure plate 742 is rotatably mounted at the bottom of the isolation plate 52. The seventh gear 741 meshes with the sixth gear 732 for transmission. The second sprocket 731 of the multiple drive groups 72 transmits power through a second chain 76. In a dynamic engagement, motor 2 71 drives one of the sprockets 2 731 to rotate. When multiple drive groups 72 are arranged in multiple layers, the inner and outer sprockets 2 731 are driven separately by chain 2 76. The sprocket 2 731 of the innermost drive group 72 is replaced by sprocket 1 711. Sprocket 3 733 is coaxially connected to sprocket 2 731 of one of the outer drive groups 72. Motor 2 71 drives sprocket 1 711 to rotate. Sprocket 1 711 and sprocket 3 733 are driven by chain 1 75.

[0050] Working principle of rotary drive mechanism 7: as shown in the attached document. Figure 9 The drive unit 72 is arranged in a 3×3 matrix. Motor 2 71 drives sprocket 1 711 to rotate. Sprocket 1 711 and sprocket 3 733 are driven by chain 1 75, which in turn drives sprocket 3 733 to rotate. A guide wheel can be added to guide the chain, increasing the contact area between the chain and the sprocket. The rotation of sprocket 3 733 drives sprocket 2 731 and gear 6 732, which are coaxially connected, to rotate. Multiple sprockets 2 731 are driven by chain 2 76 to rotate. Gear 6 732 meshes with gear 7 741 to rotate the pressure plate 742. The pressure plate 742 cooperates with the tray 321 to make the motor rotate inside the material cylinder 32. Figure 9 The arrangement and transmission method of the drive group 72 can be changed according to the specific arrangement of the material cylinder 32. When the drive group 72 is arranged in a 2×2 matrix, the second sprocket 731 is driven by the second chain 76, and the output end of the second motor 71 is directly connected to one of the second sprockets 731. When the drive group 72 is arranged in a 4×4 matrix, the inner 2×2 matrix and the outer matrix are driven by the second sprocket 731 separately. One of the inner drive groups 72 and the adjacent inner drive group 72 are coaxially equipped with a third sprocket 733 on the second sprocket 731. The two third sprockets 733 are driven by the first chain 75, and the output end of the second motor 71 is connected to one of the third sprockets 733. When the output torque of the second motor 71 is small, multiple second motors 71 can also be set. The second motors 71 control the operation of the drive group 72 in the area respectively. The above structure can be adjusted according to the size of the motor being processed. When the motor being processed is large, the above structure is cancelled, and multiple second motors 71 are set to be connected to the pressure plate 742.

[0051] Combined with appendix Figure 1 and attached Figure 12As shown, the dispensing mechanism 8 includes a fixed frame 81 located on both sides of the treatment tank 4. A walking device 82 is movably mounted on the fixed frame 81. A crossbeam 83 is connected to the top of the two walking devices 82. A transverse platform 84 is movably mounted on the crossbeam 83. A lifting platform 85 is raised and lowered on the transverse platform 84. A dispensing device 86 is mounted on the lifting platform 85. The dispensing device 86 injects the potting glue into the motor.

[0052] Working principle of dispensing mechanism 8: The fixed frames 81 on both sides of the treatment pool 4 provide stable support for the entire dispensing mechanism. The walker 82 on the fixed frame 81 can move along the fixed frame, driving the crossbeam 83 connected at the top to move synchronously, so as to realize the position adjustment of the dispensing mechanism in both directions of the treatment pool to adapt to the dispensing needs of different motors.

[0053] The transverse platform 84 on the crossbeam 83 can move laterally along the crossbeam to further adjust the glue-filling position so that it is aligned with motors in different columns of the same row; the lifting platform 85 on the transverse platform 84 can move up and down, driving the glue-filling device 86 at the bottom to adjust its height, ensuring that the glue-filling device 86 can be accurately aligned with the glue-filling port of the motor. After all components are adjusted to the appropriate position, the glue-filling device 86 accurately injects the potting glue into the motor, completing the glue-filling operation.

[0054] Through the coordinated action of the walking device 82, the transverse moving platform 84 and the lifting platform 85, the dispensing mechanism 8 achieves multi-dimensional flexible adjustment in the horizontal and vertical directions, which can accurately adapt to the motors in the multiple material cylinders arranged in the longitudinal and transverse directions, ensuring the accuracy of the dispensing position and the smoothness of the dispensing process, and effectively improving the dispensing efficiency and quality.

[0055] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
