Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing technology, and in particular to a large-scale automatic glue application assembly and inspection equipment. Background Technology

[0002] The motor stator is constructed by pressing permanent magnets, coated with adhesive, into a metal housing. The magnet fixing process directly determines the motor's performance, noise level, and lifespan, making it a critical step affecting motor quality. The reliability of magnet bonding depends on the uniformity of adhesive application, the accuracy of the adhesive application amount, and the assembly process. Deviations in any of these aspects can lead to potential problems such as magnet detachment and motor malfunction.

[0003] In existing technologies, there are two main technical solutions for fixing and assembling inner stator magnets. The first is a manual or semi-automatic station-based operation. This requires multiple operators to perform tasks such as magnet sorting, gluing, and pressing, with manual transfer of workpieces. The second is a horizontal automated gluing and assembly mode, which involves purchasing relevant equipment for production.

[0004] However, manual or semi-automatic station-based operations are lengthy, space-consuming, highly dependent on manual skills, and prone to inconsistent glue application, resulting in problems such as missed areas and glue overflow. Horizontal automated glue application and assembly modes suffer from limitations such as horizontally placed magnets, restricted field of vision, inability to clearly observe the glue application status, and high production costs. Therefore, existing technologies for fixing inner stator magnets and assembling assemblies suffer from high costs, insufficient equipment visualization and precise glue control capabilities, and inadequate reliability, requiring improvement. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide an automated glue application, assembly, and inspection device for large-scale assembly, so as to improve assembly efficiency and accuracy while reducing costs. The specific solution is as follows: A large-scale automated glue application, assembly, and inspection device includes: Assembly fixtures are used to attach and fix magnets; A glue-applying mechanism for applying glue to the surface of magnets; The loading fixture is used to fix the conveyor housing to the assembly fixture and complete the assembly of the magnet and the housing to obtain the large assembly. in: The assembly fixture is detachably connected to a rotating base, which drives the assembly fixture to rotate and causes the plurality of magnets to match the glue application mechanism in sequence. The adhesive application mechanism is equipped with a three-pronged adhesive dispensing needle for applying adhesive to the corresponding magnets.

[0006] Preferably, the equipment includes a frame, and the assembly tooling, gluing mechanism, housing fixture and rotating base are all mounted and fixed on the frame. The frame is provided with a working window on the front side, which is used for unloading the assembled parts.

[0007] Preferably, the working window is equipped with a safety light curtain.

[0008] Preferably, the loading fixture includes a housing clamp, which is provided with a loading lifting unit for driving lifting, a housing inlet located on the front side, and a fixing plate for fitting and fixing the housing into the housing inlet.

[0009] Preferably, the fixed plate is provided with a fixed driver for driving linear forward and backward movement and a mating block corresponding to the feed port position of the housing and for matching and fitting with the housing.

[0010] Preferably, the feeding fixture is equipped with a portrait inspection unit, which is used to check whether the adhesive coating position on the surface of the magnet has shifted.

[0011] Preferably, the glue application mechanism is equipped with a glue heater and a screw valve glue dispenser, and the three-pronged glue dispensing needle is detachably connected to the outlet end of the screw valve glue dispenser.

[0012] Preferably, the glue application mechanism is provided with a glue application lifting unit for driving the screw valve glue dispenser to move vertically and a glue application traversing unit for moving horizontally.

[0013] Preferably, the front end of the equipment frame is provided with a discharge bracket, the discharge bracket is provided with a discharge chute that matches the assembly tooling and a control unit for manual drive control of start and stop.

[0014] Preferably, the control method of this large automatic gluing assembly and inspection equipment is as follows: First, multiple magnets are fixed on the assembly fixture and the assembly fixture is fixed on the rotating base. While the rotating base drives the assembly fixture to rotate, the gluing mechanism applies glue to the multiple magnets sequentially from bottom to top. Then, after the machine housing is fixed in the feeding fixture, the feeding fixture matches the assembly fixture to attach and fix the glued magnets to the inner wall of the machine housing. Finally, the material is discharged.

[0015] As can be seen from the above solutions, this application provides a large-scale automatic glue application assembly and inspection device, which has the following beneficial effects: 1. By using a rotating base to drive the assembly fixture to rotate, and cooperating with the glue application mechanism to apply glue to the magnets vertically from bottom to top, the use of a three-pronged glue dispensing needle to dispense glue at multiple points simultaneously effectively avoids the problems of glue accumulation and glue volume fluctuations that are prone to occur in horizontal glue application. Furthermore, the rotation drive of the rotating base ensures that multiple magnets are precisely aligned with the glue application positions in sequence. Under the precise glue dispensing control of the screw valve glue dispenser, the glue adheres evenly to the surface of the magnets, thereby solving the problems of glue accumulation at the glue application port and glue overflow at the end face, significantly improving the consistency and stability of glue application; 2. By integrating magnet fixing, vertical gluing, gluing inspection, casing pressing, and material unloading into a single unit, and combining the coordinated actions of the rotating base, gluing lifting unit, gluing lateral movement unit, material loading lifting unit, and casing clamps, this system achieves automated, high-precision operation while replacing manual substations and semi-automatic processes. Furthermore, the vertical, top-to-bottom pressing method prevents glue misalignment under pressure, and the fully automated process shortens the production cycle, reduces reliance on manual labor and floor space, significantly improving overall production efficiency and product assembly accuracy. 3. The image inspection unit performs full inspection of the glue application position, glue shape, and glue amount of each magnet, and identifies defects such as glue application deviation, insufficient glue, and glue overflow in real time. This allows for real-time interception of defective products in conjunction with the glue application and assembly processes, replacing manual sampling and visual judgment. This solves the problems of lack of quality monitoring and untraceable data in the traditional model, and significantly improves the reliability and pass rate of automotive window motor stator magnet assembly.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] It should be noted that the feeding lifting unit 33, the glue application lifting unit 43, and the glue application transverse movement unit 44 in this embodiment are all driven by corresponding linear drivers, which will not be described in detail here.

[0021] As shown in Figure 1, a large-scale automatic glue application, assembly, and inspection device includes a frame 1, an assembly fixture 2, a glue application mechanism 4, and a loading fixture 3. The assembly fixture 2 is used to attach and fix magnets 21, improving the positioning accuracy of the magnets 21 and preventing displacement during glue application and assembly. The glue application mechanism 4 is used to apply glue to the surface of the magnets 21, achieving quantitative and uniform glue dispensing and ensuring reliable bonding. The loading fixture 3 is used to fix and convey the housing to the assembly fixture 2, and complete the assembly of the magnets 21 and the housing to obtain the large-scale assembly, realizing automatic housing loading and precise alignment assembly, and improving assembly consistency.

[0022] As shown in Figure 2, a discharge bracket 5 is provided at the front end of the equipment frame 1. The discharge bracket 5 is equipped with a discharge chute 51 that matches the assembly fixture 2 to ensure smooth discharge of finished products, as well as a control unit 52 for manual drive control of start and stop, which facilitates on-site operation and emergency control.

[0023] As shown in Figures 1, 2, and 3, the assembly fixture 2 is detachably connected to a rotating base 22, facilitating quick assembly and improving equipment versatility. The rotating base 22 drives the assembly fixture 2 to rotate, causing multiple magnets 21 to sequentially match with the gluing mechanism 4, achieving precise indexing and ensuring uniform gluing positions for each magnet 21. The gluing mechanism 4 is equipped with a three-pronged glue dispensing needle 421 for applying glue to the corresponding magnets 21, enabling simultaneous multi-point glue dispensing, resulting in uniform glue application and preventing accumulation.

[0024] The assembly fixture 2, the gluing mechanism 4, the housing clamp 31, and the rotating base 22 are all mounted and fixed on the equipment frame 1, improving the overall structural rigidity and operational stability. The equipment frame 1 is equipped with a front-mounted working window 11. The working window 11 is used for unloading large assemblies, facilitating workpiece handling and monitoring. Simultaneously, to enhance safety, a safety light curtain 12 is installed in the working window 11 to prevent accidental insertion and ensure operational safety.

[0025] As shown in Figures 2 and 4, the loading fixture 3 includes a housing clamp 31. The housing clamp 31 is equipped with a loading lifting unit 33 for driving the lifting mechanism, providing a stable downward pressure assembly force; a housing inlet 311 located at the front for smooth housing loading; and a fixing plate 32 for attaching and fixing the housing into the inlet 311, increasing the clamping contact area and making the fixation more reliable. The fixing plate 32 is equipped with a fixing driver 322 for driving linear forward and backward movement, and a mating block 321 corresponding to the housing inlet 311 and for matching and fitting with the housing, achieving centering and clamping of the housing and ensuring assembly coaxiality. When the housing is being fed, it first enters the housing clamp 31 through the housing inlet 311, and then the fixing plate 32 is driven to match and fix the housing. The loading lifting unit 33 then drives the housing to descend and assemble with the magnet 21 coated with adhesive. Fixing before pressing prevents adhesive from being squeezed and shifted.

[0026] It should be noted that, in order to further improve the glue application accuracy and thus enhance assembly stability, a portrait inspection unit 34 is installed on the loading fixture 3, located close to the glue application station, providing fast detection response and high accuracy. The portrait inspection unit 34 is used to check whether the glue application position on the surface of the magnet 21 has shifted, achieving full inspection of the glue application status and timely interception of defective products.

[0027] In this embodiment, the glue application mechanism 4 is equipped with a glue heater 41 and a screw valve glue dispenser 42. Heating improves the flowability of the glue, and the screw valve ensures accurate and stable glue dispensing. The three-pronged glue dispensing needle 421 is detachably connected to the outlet end of the screw valve glue dispenser 42 for easy replacement and maintenance, and adaptability to different glue application specifications. Therefore, the glue is first heated by the glue heater 41 before being dispensed, and then quantitatively dispensed by the screw valve glue dispenser 42. The glue is then applied to the surface of the magnet 21 by the dispensing from the three-pronged glue dispensing needle 421. Heating, quantitative dispensing, and multi-point glue dispensing work together to improve the stability of glue application quality. At the same time, the glue application mechanism 4 is equipped with a glue application lifting unit 43 for driving the screw valve glue dispenser 42 to move vertically and a glue application lateral movement unit 44 for moving horizontally, which flexibly adjusts the glue application position to adapt to magnets 21 of different sizes. Therefore, by driving the three-pronged glue dispensing needle 421 to move, the accuracy and stability of the cooperation between the three-pronged glue dispensing needle 421 and the magnet 21 can be improved, ensuring consistent glue application gap and better glue application uniformity.

[0028] In use, firstly, multiple magnets 21 are fixed on the assembly fixture 2, and the assembly fixture 2 is fixed on the rotating base 22. While the rotating base 22 drives the assembly fixture 2 to rotate, the gluing mechanism 4 applies glue to the multiple magnets 21 sequentially from bottom to top. Applying glue from bottom to top avoids glue accumulation at the needle tip. After the machine housing is fixed in the feeding fixture 3, the feeding fixture 3 matches the assembly fixture 2, and the glued magnets 21 are attached and fixed to the inner side wall of the machine housing. Vertical alignment and pressing ensure that the glue is applied evenly and the adhesion is firm. Finally, the material is discharged. The entire process is automated, with a fast production cycle and low reliance on manual labor.

[0029] In summary, this application provides a large-scale automatic glue application and assembly inspection device. This device uses a rotating base 22 to drive the assembly fixture 2 to rotate, and coordinates with the glue application mechanism 4 to apply glue to the magnets 21 from bottom to top vertically. A three-pronged glue dispensing needle 421 dispenses glue at multiple points simultaneously, effectively avoiding the problems of glue accumulation and glue volume fluctuations that easily occur with horizontal glue application. Furthermore, the rotation of the rotating base 22 drives multiple magnets 21 to precisely align with the glue application positions in sequence. Under the precise glue dispensing control of the screw valve glue dispenser 42, the glue adheres evenly to the surface of the magnets 21, thereby solving the problems of glue accumulation at the glue application port and glue overflow at the end face, significantly improving the consistency and stability of glue application.

[0030] This application integrates magnet 21 fixing, vertical gluing, gluing inspection, housing pressing, and material unloading into a single device. The coordinated actions of the rotating base 22, gluing lifting unit 43, gluing lateral movement unit 44, loading lifting unit 33, and housing clamp 31 achieve automated high-precision operation while replacing manual substations and semi-automatic operations. The vertical top-to-bottom pressing method prevents glue misalignment under pressure, and the fully automated process shortens the production cycle, reduces reliance on manual labor and floor space, significantly improving overall production efficiency and product assembly accuracy. Simultaneously, the image inspection unit 34 performs full inspection of the gluing position, glue shape, and glue amount for each magnet 21, identifying defects such as gluing misalignment, insufficient glue, and glue overflow in real time. This coordinated operation with the gluing and assembly processes intercepts defective products in real time, replacing manual sampling and visual judgment. This solves the problems of lack of quality monitoring and untraceable data in traditional methods, significantly improving the reliability and pass rate of the automotive window motor stator magnet 21 assembly.
