Description
Technical Field
[0001] This invention belongs to the technical field of balance clamp production equipment, and particularly relates to a balance clamp magnetization device and its usage method. Background Technology
[0002] Balance clips are core components in micro motors, precision damping components, and electronic transmission parts. To achieve functions such as magnetic positioning and shock absorption, small permanent magnets need to be firmly bonded to the pre-set bonding surface of the balance clip using adhesive. This magnetization process directly determines the dynamic balance accuracy and magnetic durability of the finished product. Currently, most small and medium-sized parts processing plants in China use a purely manual assembly line operation mode for the magnetization of balance clips. The complete process consists of five steps: manually picking up the balance clip, manually applying adhesive with a hand glue gun, manually grasping and aligning the magnets, manually pressing and maintaining pressure, and manually collecting the finished product. This entire process has many unavoidable production defects, which seriously restricts mass production capacity and product consistency.
[0003] Firstly, manual operation results in low production efficiency and continuously rising labor costs. A single skilled worker can only complete 8 to 12 balancing clamp magnetic operations per minute. The repetitive actions of picking up materials, applying glue, and bonding for long periods of time easily lead to physical fatigue, and production capacity further declines during the afternoon and night shifts. Enterprises need to set up multiple dedicated operators to guard the workstations, while also providing material handling, quality inspection, and other support personnel. Labor costs account for a large proportion of production costs, and the management costs caused by recruitment and staff turnover continue to increase, making it difficult to adapt to the production needs of large-volume, continuous orders.
[0004] Secondly, manual gluing and bonding precision are uncontrollable, resulting in low product yield. Glue application relies entirely on worker feel, making it prone to issues such as missed areas, insufficient glue, glue overflow, and glue line misalignment. Manual alignment of magnets can lead to angular and positional deviations, and there's no standardized bonding pressure. Excessive pressure causes glue to overflow and contaminate the balance clamp surface, while insufficient pressure results in excessively large bonding gaps, leading to incomplete magnet adhesion and eventual detachment. Furthermore, the strong magnetic force of the magnets makes them easily attracted and stuck together during manual handling, causing chipping and defects during separation. This results in significant variations in bonding strength between batches, with the factory inspection failure rate consistently exceeding 10%, significantly increasing rework and scrap costs.
[0005] Thirdly, the poor working environment poses safety and quality risks. Long-term direct contact with volatile adhesives can easily cause skin and respiratory discomfort for workers. Manual operations lack enclosed protective measures, allowing dust and debris to easily adhere to uncured adhesive surfaces, resulting in impurities in the bonding process. Magnets and balancing clamps are scattered, and the material handling lacks a standardized feeding structure, leading to frequent problems such as mixed materials, reversed loading / unloading, and inverted magnetic poles. Defective products flowing into downstream assembly processes can cause motor dynamic imbalance, abnormal operating noises, and other overall machine malfunctions.
[0006] Fourth, existing simple auxiliary tooling cannot achieve full-process linkage. The few simple fixtures on the market can only place a balancer or magnet, and cannot simultaneously complete the integrated operation of automatic feeding, simultaneous gluing, automatic gripping and bonding, and finished product stacking and unloading. Manual step-by-step workpiece transfer is still required, resulting in many process interruptions and preventing the formation of a continuous automated production line. This fails to fundamentally solve the efficiency and quality shortcomings caused by manual processes. Based on the above-mentioned defects in existing processes, this invention proposes a fully automatic balancing clamping and magnetizing device, realizing fully automated processing of workpiece automatic feeding, simultaneous gluing and magnetizing, and stacking and unloading with mutually repelling magnetic poles. Summary of the Invention
[0007] The purpose of this invention is to address the aforementioned technical problems by providing a balanced clamping magnet device and its usage method, thereby effectively improving the production efficiency and quality of balanced clamping magnet operations.
[0008] In view of this, the present invention provides a balancing clamp magnetizing device, including a body, a horizontal working platform is provided on the top of the body, and a balancing clamp guiding mechanism, a magnet feeding mechanism, an adhesive bonding mechanism and a finished product discharge mechanism are integrated on the working platform; a vibrating feeding plate is provided on one side of the body to form a feeding mechanism, and the discharge channel of the vibrating feeding plate is connected to the balancing clamp guiding mechanism for sequentially feeding the sorted balancing clamps into the guiding mechanism.
[0009] The balancing clamp guiding mechanism is mounted on the working platform and is a linear pushing structure with vertical and horizontal connections. It is used to sequentially transport the balancing clamps to the gluing station, bonding station, and discharge station. It includes a transverse guide platform distributed along the transverse side of the machine body and a longitudinal guide platform located on the front right side of the transverse guide platform. The upper surface of the transverse guide platform has a transverse guide groove extending along its own length. A transverse push rod is provided at the right end of the transverse guide groove, which is driven by a linear drive structure to push the balancing clamp to reciprocate along the transverse guide groove. The longitudinal guide platform has a longitudinal guide groove extending along its own length. The rear end of the longitudinal guide groove is perpendicularly connected to the transverse guide groove, and the front end of the longitudinal guide groove is provided with a longitudinal push rod for pushing the balancing clamp into the transverse guide groove. The discharge channel of the vibrating feeder is connected to the front end of the longitudinal guide groove.
[0010] The magnet feeding mechanism is set on the working platform and located on the left side of the horizontal guide platform. It adopts a structure of vertical stacking and bottom horizontal pushing for discharging, and is used to output magnets one by one. It includes a magnet storage column set vertically at the left end of the horizontal guide platform. The magnet storage column has a vertically penetrating magnet receiving groove, and the magnets are stored in the magnet receiving groove in a vertically stacked manner. The bottom of the magnet storage column has a horizontally penetrating magnet guiding groove, and the magnet guiding groove has a magnet pushing rod, which is driven by a linear drive structure to push the bottom magnet of the stack horizontally to the picking station in sequence.
[0011] The adhesive application and bonding mechanism is set on the working platform and located behind the balance clamp guiding mechanism. It includes an installation platform that can move two-dimensionally in a vertical plane, and an adhesive application head and a magnetic gripping head fixed on the installation platform. The adhesive application head and the magnetic gripping head can move horizontally and vertically synchronously with the installation platform to simultaneously apply adhesive to the balance clamp and pick up the magnetic material, and attach the magnet to the surface of the balance clamp after adhesive application.
[0012] The adhesive application head includes an adhesive inlet connector, a flow guide pipe, and a coating nozzle. The input end of the adhesive inlet connector is connected to an external adhesive supply device, and the output end is connected to the coating nozzle through the flow guide pipe. An on / off control valve and a backflow control valve are connected in series on the flow guide pipe. The on / off control valve controls the supply of adhesive, and the backflow control valve is used to backflow adhesive from the nozzle tip when the adhesive supply stops to prevent dripping and stringing. The coating nozzle has a gradient chamber that changes sequentially along the adhesive outlet direction. The gradient chamber contains a flow divider and a flow equalization / layering member, ensuring that the adhesive is output from the nozzle outlet in a uniform, ribbon-like form.
[0013] The magnetic gripping head includes a gripping head body and an elastic ejection assembly. The gripping head body is mounted on the mounting platform and located to the left of the adhesive application head. An axially parallel mounting hole is formed on the adsorption surface of the gripping head body. A top plate, a fixing seat, and an elastic element are installed within the hole. The fixing seat is threaded to the inner end of the mounting hole. The elastic element is a compression spring sleeved on the outside of the fixing seat. The inner side of the top plate is connected to the outer end of the compression spring. In its natural state, the outer side of the top plate protrudes beyond the mounting hole and the adsorption surface of the gripping head body. When the magnet is adsorbed, the top plate is compressed and retracts to store energy. When released, the compression spring rebounds, forcibly pushing the magnet away from the adsorption end face, and the spring force completes the pressure-holding operation.
[0014] The finished product discharge mechanism is located in front of the balance clamp guiding mechanism and adopts a horizontal pushing and feeding, magnetic pole repulsion vertical stacking structure. It includes a discharge guide platform arranged longitudinally along the machine body, located to the left of the longitudinal guide platform. The discharge guide platform has a discharge guide groove extending along its length, with its rear end connected to a transverse guide groove. A discharge push rod is located behind the transverse guide platform, coaxially arranged with the discharge guide groove, used to push the magnetized balance clamps into the discharge guide groove. A balance clamp storage column is vertically installed on the discharge guide platform, with a vertically penetrating finished product receiving groove inside. A magnetic repulsion component is located directly below the finished product receiving groove corresponding to the discharge guide groove. The magnetic repulsion component and the magnet on the balance clamp are arranged with the same poles opposite each other, using the magnetic pole repulsion force to create a gap at the bottom of the finished product receiving groove for the balance clamps to push linearly, allowing the magnetized balance clamps to be pushed horizontally in sequence and stacked upwards.
[0015] Furthermore, the gradient chamber of the coating nozzle is successively a shrinkage section, a diffusion section, and a uniform pressure section along the glue discharge direction; the flow splitting component is a symmetrically distributed multi-component flow splitting rib, and the spacing between the flow splitting ribs gradually increases along the glue discharge direction; the flow uniform layering component is at least one parallel flow uniform sheet, and the flow uniform sheet is arranged perpendicular to the glue thickness direction.
[0016] Furthermore, the backflow control valve is arranged downstream of the on / off control valve and is a pneumatic diaphragm structure, including a valve body, a piston body, a diaphragm, and a return spring. The valve body has an air connection port, the piston body is located inside the valve body, and an actuator rod is fixed on its lower side. The diaphragm is located at the through hole at the lower end of the valve body and seals the through hole from the inside of the guide pipe. The return spring is sleeved on the outside of the actuator rod, with its two ends abutting against the lower side of the piston body and the inner wall of the valve body, respectively. When compressed air is introduced into the upper part of the valve body, the piston body compresses the return spring and causes the diaphragm to concave. When the air is cut off, the return spring drives the piston body to return to its original position and causes the diaphragm to convex, forming a negative pressure environment in the guide pipe to backflow the adhesive. The airflow control valve is equipped with an airflow speed regulating element at the air interface to control the adhesive backflow speed to be no more than 10 mm / s and the backflow stroke to be no more than 20 mm.
[0017] Furthermore, the on / off control valve is a pneumatic piston-type shut-off valve, including a valve body, a piston valve core slidably mounted in the valve body, and a return spring; the valve body is provided with an air passage interface connected to a compressed air source. When compressed air is introduced, the piston valve core compresses the return spring and opens the adhesive flow channel. When the air is cut off, the return spring pushes the piston valve core to reset and cut off the adhesive flow channel; an airflow speed regulating element is configured at the air passage interface to adjust the opening and closing speed of the valve core.
[0018] Furthermore, a limiting boss is provided at the outer end of the fixing seat to limit the axial position of the compression spring and prevent the spring from coming out.
[0019] Furthermore, the magnetic repulsion component is a permanent magnet or an electromagnet, with its upper end face flush with or embedded below the bottom surface of the discharge guide trough; the height of the pushing gap formed by the mutual repulsion of the magnetic poles is greater than the thickness of a single balance clamp, ensuring that the discharge push rod can smoothly push the finished product to the bottom of the finished product receiving trough.
[0020] Furthermore, the transverse push rod, longitudinal push rod, magnetic push rod, and discharge push rod are all driven by pneumatic cylinders or electric push rods, and each drive structure is fixedly installed at the corresponding position on the working platform.
[0021] Furthermore, the installation platform is driven by a cross slide module and can move linearly in the horizontal and vertical directions; the distance between the glue application head and the magnetic gripping head on the installation platform matches the distance between the glue application station and the magnetic material picking station on the horizontal guide platform, so that the glue application and material picking actions are completed simultaneously.
[0022] Correspondingly, the present invention also provides a method of using the above-mentioned balanced clamp magnetic device, comprising the following steps: S1. Workpiece feeding and conveying: After being vibrated and sorted by the balance clamp, the workpiece enters the longitudinal guide table, is pushed longitudinally to the transverse guide table, and is then conveyed to the gluing station by the transverse push rod; magnets are stored in a vertical stacking manner and are pushed one by one to the picking station by the bottom magnet push rod. S2. Synchronous operation of gluing and material handling: The glue application head and the magnetic gripper head move synchronously in two dimensions. The glue application head moves to the glue application station, and the glue is evenly distributed and spread on the surface of the balance clamp in a uniform strip shape after being divided and evenly distributed in the internal flow. When the glue application is stopped, the glue at the end of the nozzle is sucked up by the back suction action to prevent dripping. At the same time, the magnetic gripper head moves to the material handling station to attract the magnet. The elastic ejection component on the gripper end face is compressed and retracts to store energy. S3. Magnet bonding and curing: The magnet gripping head with the magnet adsorbed is moved to the top of the balanced clamp after the glue has been applied. The magnet gripping head is released from adsorption, and the elastic ejector component rebounds to force the magnet away from the gripping end face, so that the magnet is flatly bonded to the glue layer surface of the balanced clamp. At the same time, pressure is maintained to complete the magnetization process. S4. Finished product stacking and unloading: The magnetized balance clamp is pushed to the unloading guide platform. The magnetic repulsion component located below the finished product stacking position and the magnet on the balance clamp repel each other, forming a horizontal pushing gap at the bottom of the stack. After the finished product is pushed horizontally into the gap, it is lifted upward, realizing the vertical stacking and storage of finished products in sequence.
[0023] The beneficial effects of this invention are: 1. Through an integrated modular layout of vibration feeding and sorting, longitudinal and transverse linear conveying, synchronous gluing and material picking, automatic bonding and pressure holding, and mutually exclusive stacking and material discharge, the fully automatic continuous processing of the balanced clamping and magnetic process is realized. There is no need for manual loading and unloading or transfer. The single equipment capacity can reach 5 to 8 times that of manual operation, which greatly reduces labor costs and on-site management costs, and can stably adapt to the continuous production needs of large-volume orders.
[0024] 2. The coating nozzle adopts a three-section gradient chamber combined with a flow-dividing rib and a uniform flow sheet internal structure, which effectively compensates for the defect of fast flow velocity in the center and slow flow velocity at the edge of the adhesive. This allows the high-viscosity adhesive to form a strip-shaped adhesive film with uniform thickness and neat edges at the outlet, and the thickness deviation of the adhesive layer can be controlled within ±0.02mm. With the upstream and downstream on / off control valves and back suction control valves, the adhesive is sucked from the nozzle end by the diaphragm deformation at the moment of adhesive stoppage, which completely solves the problems of stringing and dripping when adhesive is stopped, avoids adhesive contamination of the workpiece surface and equipment table, and reduces cleaning and maintenance costs.
[0025] 3. The magnetic gripper head adopts an adsorption-type material picking method, with an elastic ejection component built into the end face. When picking up the material, the spring is compressed and stores energy. When released, the spring rebounds and forcibly pushes the magnet away from the adsorption surface, completely solving the problem of magnet offset and detachment caused by residual magnetism. The bonding position accuracy is significantly improved. At the same time, the elastic pressure of the spring during the ejection process can maintain pressure on the magnet for a short time, so that the adhesive layer is evenly spread and internal air bubbles are expelled, effectively improving the bonding strength and batch consistency, and reducing the defect rate of incomplete adhesion and detachment.
[0026] 4. The finished product unloading utilizes the magnetic force of like poles repelling each other to form a stable pushing gap at the bottom of the stack. After the finished product is pushed in horizontally, it is automatically lifted and stacked upwards without the need for an additional power lifting mechanism. The structure is simple and reliable. It completely avoids the defects of workpiece collision and magnet edge chipping caused by traditional free-falling methods. The finished products are stacked neatly and orderly. After being taken out, they can be directly transferred to the next process without the need for manual secondary sorting. Attached Figure Description

Detailed Implementation
[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0041] like Figures 1-10 As shown in this embodiment, a balancing clamp magnetizing device includes a main body 1, which is constructed from aluminum profiles and has a cabinet-like structure. The internal components can accommodate electrical control components and pneumatic components. A horizontal work platform 2 is fixedly installed on the top of the main body 1. The work platform 2 is made of aluminum alloy sheet with a hard anodized surface, making it wear-resistant and resistant to adhesive adhesion. The left-right extension direction of the main body is defined as the transverse direction, and the front-back extension direction as the longitudinal direction. The work platform 2 is functionally integrated with a balancing clamp guiding mechanism 24, a magnet feeding mechanism 35, an adhesive application and bonding mechanism 46, and a finished product discharge mechanism 57. A vibrating feeder 13 is located on the right front side of the main body 1, serving as a feeding mechanism to continuously supply the sorted workpieces to the balancing clamp guiding mechanism 24.
[0042] 1. Balance clamp guide mechanism 2 The balance clamp guiding mechanism 2 is an L-shaped linear pushing structure with vertical and horizontal connections. It undertakes the functions of transferring balance clamp workpieces and switching workstations. It mainly consists of two parts: the horizontal guide table 20 and the vertical guide table 23.
[0043] A transverse guide platform 20 is fixedly installed in the middle of the work platform along the transverse direction. It is made of aluminum alloy, stainless steel, or wear-resistant engineering plastic. A transverse guide groove 21 running through the transverse direction is opened on its upper surface. The transverse guide groove 21 is an upward-opening groove structure with openings at both ends. The cross-sectional contour of the groove is adapted to the outer contour of the balance clamp. A sliding gap of 0.1~0.2mm is reserved on each side to ensure that the balance clamp can slide smoothly along the groove without deflection or jamming. A transverse drive cylinder is set on the right side of the transverse guide platform 20. The cylinder is fixed to the work platform by a cylinder support. The end of the cylinder piston rod is connected to a transverse push rod 22. The transverse push rod 22 extends into the transverse guide groove 21. The end of the push rod is equipped with a push head adapted to the end face of the balance clamp. Driven by the cylinder, it can move back and forth along the transverse guide groove 21, pushing the balance clamp on the right side to the left in sequence to the gluing station, bonding station, and unloading station. The transverse drive cylinder is equipped with a magnetic ring switch, which can precisely control the pushing stroke and ensure the positioning accuracy of the workstation.
[0044] The longitudinal guide platform 23 is fixedly installed on the front side of the right end of the transverse guide platform 20, and is perpendicular to the transverse guide platform 20. A longitudinal guide groove 24 extending longitudinally is opened in the longitudinal guide platform 23. The cross-section of the groove is also adapted to the contour of the balance clamp. Its rear end is perpendicularly connected to the transverse guide groove 21, and its front end is connected to the direct vibration discharge channel of the vibrating feed plate 1. A longitudinal drive cylinder is fixed at the front end of the longitudinal guide platform 23. Its piston rod is connected to the longitudinal push rod 25, which can push the balance clamp at the front feed port backward into the transverse guide groove 21 to complete the feeding transfer.
[0045] During operation, the vibrating feeder 1 sorts and orients the disordered balance clamps and feeds them one by one into the front end of the longitudinal guide groove 24. The longitudinal pusher rod 25 extends and pushes the workpiece into the transverse guide groove 21. Then the transverse pusher rod 22 moves to the left and transports the workpiece to the corresponding station, realizing the orderly flow of the workpiece.
[0046] II. Magnet feeding mechanism 3 The magnet feeding mechanism 3 is located at the left end of the horizontal guide platform 20. It adopts a vertical stacking storage and bottom horizontal pushing discharge method, which can stably output magnets one by one. It mainly includes a magnet storage column 30, a magnet push rod 33 and a magnet driving cylinder.
[0047] The magnet storage column 30 is a vertical column structure made of non-magnetic stainless steel or polyoxymethylene material to avoid magnetic adsorption causing material jamming. It is vertically fixed to the upper surface of the left end of the horizontal guide table 20 by bolts. The magnet storage column 30 has a vertically through magnet receiving groove 31 inside. The groove cross-section is adapted to the outline of the magnet, with a gap of 0.1~0.15mm on one side. The magnets are vertically stacked in the groove with the magnetic poles aligned. The top opening is a feeding port, which can directly add magnets into the groove.
[0048] The bottom of the magnet storage column 30 has a horizontally penetrating magnet guide groove 32. The length of the magnet guide groove 32 coincides with the horizontal guide groove 21. The height of the groove is slightly greater than the thickness of a single magnet, with the difference controlled within 0.05~0.1mm, ensuring that only the bottom magnet falls into the guide groove each time, achieving single-magnet output. A magnet drive cylinder is installed on the left side of the horizontal guide platform 20, which is fixed to the working platform by a bracket. The cylinder piston rod is connected to the magnet push rod 33. The magnet push rod 33 extends into the magnet guide groove 32, which can push the bottom magnet to the right to the picking position at the left end of the horizontal guide groove 21. After pushing is completed, the cylinder resets, and the upper magnet falls down to fill the position under the action of gravity, waiting for the next output.
[0049] A through-beam photoelectric sensor can be installed on the upper part of the magnet storage column 30 to detect the amount of magnets in the tank. When the amount is lower than the set value, a replenishment prompt will be issued to avoid material shortage and machine shutdown.
[0050] III. Adhesive Application and Bonding Mechanism 4 The adhesive application and bonding mechanism 4 is the core actuator of the equipment. It achieves parallel operation of adhesive application and material handling through a synchronously moving dual-station structure, which greatly shortens the processing cycle. It mainly includes a cross slide module, an installation platform 40, an adhesive application head 41, and a magnetic gripping head 42.
[0051] The cross slide module is fixed to the rear of the work platform by a vertical bracket. It is composed of a horizontal linear module and a vertical linear module, which can drive the installation platform 40 to move in two-dimensional linear motion within the vertical plane formed by the horizontal and vertical directions. The installation platform 40 is a vertical mounting plate, fixed to the sliding block of the vertical linear module. A magnetic gripping head 42 is fixed to the left side of the front end face of the installation platform 40, and an adhesive application head 41 is fixed to the right side. The horizontal distance between the two is exactly the same as the horizontal distance between the adhesive application station and the material picking station on the horizontal guide chute 21. When the installation platform 40 moves horizontally, the adhesive application head 41 is aligned with the adhesive application station, and the magnetic gripping head 42 is aligned with the material picking station. The adhesive application and material picking actions can be completed simultaneously, which can shorten the cycle time of a single station by about 40% compared with the step-by-step operation.
[0052] 1. Magnetic gripping head 42 The magnetic gripping head 42 mainly includes a gripping head body 420 and an elastic ejection component. The gripping head body 420 is made of non-magnetic stainless steel. It can be equipped with a vacuum adsorption channel or a built-in micro electromagnet. In this embodiment, the built-in micro electromagnet solution is adopted. When energized, it generates magnetic force to attract the magnet. When de-energized, the magnetic force disappears and the magnet is released. The structure is simple and the adsorption force is stable.
[0053] A mounting hole 421 extending axially is provided at the center of the lower adsorption surface of the gripping head body 420. The mounting hole 421 is a stepped circular hole with a smaller inner diameter and internal threads in the upper section and a larger inner diameter in the lower section, used to accommodate the elastic ejection assembly. The elastic ejection assembly includes a fixed seat 422, a compression spring 423, and a top plate 424: The fixed seat 422 is a columnar member with external threads or a columnar member with holes. It is screwed into the upper section of the mounting hole 421 to achieve threaded fixation or is threadedly fixed by bolts to the gripping head body 420. Its lower end is provided with a radially outwardly extending annular limiting boss 425; The compression spring 423 is coaxially sleeved on the outer side of the lower section of the fixed seat 422. The upper end of the spring abuts against the stepped end face of the mounting hole 421, and the lower end abuts against the inner end face of the top plate 424; The top plate 424 is a circular wear-resistant thin sheet that is slidably assembled in the lower section of the mounting hole 421 and can slide slightly axially.
[0054] In its natural state, the compression spring 423 is in an extended state, and the outer end face of the top plate 424 protrudes about 0.5~1mm from the adsorption end face of the gripping head body 420. When the gripping head adsorbs the magnet downwards, the magnet end face pushes the top plate 424 inward to compress the spring 423. The spring stores energy, and the magnet is adsorbed and fixed by the electromagnet to the adsorption end face. When the magnet is released, the electromagnet is de-energized and demagnetized, the compression spring 423 quickly rebounds, pushes the top plate 424 outward, and forcibly pushes the magnet away from the adsorption end face, completely avoiding magnet adhesion and displacement caused by residual magnetism. At the same time, the elastic thrust of the spring can provide a holding pressure time of 0.5~2 seconds after the magnet adheres to the adhesive layer, so that the adhesive layer is evenly spread and air bubbles are expelled, improving the bonding strength.
[0055] For larger magnets, three sets of elastic ejection components can be arranged symmetrically or triangularly on the adsorption end face to ensure uniform ejection force and flat magnet fit.
[0056] 2. Glue applicator head 41 The glue application head 41 is composed of a glue inlet connector 410, a flow guide pipe 411, an on / off control valve 412, a back suction control valve 413, and a coating nozzle 414 connected in series to achieve precise glue supply, uniform coating, and glue stop to prevent dripping.
[0057] The glue inlet connector 410 is a standard external threaded connector. The upper end is connected to an external pressure glue tank or precision glue pump through a glue-resistant hose, and the lower end is connected to the flow guide pipe 411. The flow guide pipe 411 is made of polytetrafluoroethylene or stainless steel, with a smooth and corrosion-resistant inner wall to reduce glue residue and curing blockage.
[0058] The on / off control valve 412 is connected in series in the upstream section of the guide pipe 411. It is a pneumatic piston-type shut-off valve structure, including a valve body. Inside the valve body, there is an axially sliding piston valve core 4120. A sealing ring is set around the circumference of the valve core. An annular valve seat is fixed on the inner wall of the valve body, and the center of the valve seat has a glue passage hole. A return spring 4134 is set above the piston valve core 4120. An air passage interface is opened on the upper part of the valve body, which is connected to a compressed air pipeline. When compressed air is introduced into the air passage interface, the air pressure pushes the piston valve core 4120 to move, compressing the return spring 4134, and the valve core moves away from the valve seat, opening the glue flow channel. When the compressed air is cut off, the return spring 4134 pushes the piston back to its original position, the valve core presses against the valve seat, and the glue supply is cut off. An airflow speed regulating valve is connected in series at the air passage interface, which can adjust the intake and exhaust speeds to control the opening and closing speed of the valve core and avoid glue volume fluctuations caused by water hammer effect.
[0059] The backflow control valve 413 is arranged in series downstream of the on / off control valve 412. It is a pneumatic diaphragm 4133 type backflow structure, including a valve body 4130. Inside the valve body 4130, there is a piston body 4131. The lower end of the piston body 4131 is coaxially connected to an actuator rod 4132. The lower end of the actuator rod 4132 is fixedly connected to a diaphragm 4133. The diaphragm 4133 is made of fluororubber material that is resistant to adhesive corrosion. Its edges are sealed and pressed against the inner wall of the valve body 4130, dividing the valve body cavity into an upper chamber and a lower chamber. The lower chamber is connected to the adhesive flow channel of the guide pipe 411. A return spring 4134 is sleeved below the piston body 4131. The upper and lower ends of the spring abut against the lower end face of the piston body 4131 and the stepped surface of the inner wall of the valve body, respectively. An air passage interface is opened on the upper part of the valve body 4130 to connect to a compressed air pipeline.
[0060] When compressed air is introduced into the air port on the valve body 4130, the air pressure pushes the piston body 4131 downward, compressing the return spring 4134. The actuator 4132 causes the diaphragm 4133 to sink downward, allowing the adhesive to flow normally. When the adhesive is stopped, the on / off control valve 412 first cuts off the upstream adhesive supply. At the same time, the air port on the valve body 4130 is shut off. The return spring 4134 pushes the piston body 4131 back to its original position. The actuator 4132 causes the diaphragm 4133 to bulge upward. The volume of the guide pipe 411 decreases instantaneously, forming a local negative pressure. This creates a back suction effect on the adhesive at the downstream nozzle end, drawing the residual adhesive from the nozzle inward to prevent dripping and stringing.
[0061] In this embodiment, an airflow speed control valve is also connected in series at the air passage interface of the valve body 4130. By controlling the exhaust speed, the back suction speed can be precisely adjusted, keeping the adhesive back suction speed within 10mm / s and the back suction stroke within 20mm, thus avoiding excessive back suction that could cause air to enter the pipeline and generate bubbles. The air passages of the on / off control valve 412 and the back suction control valve 413 are connected in parallel to the same solenoid valve for control, achieving precise matching of the opening and closing sequence and completely eliminating the problem of adhesive dripping when the flow stops.
[0062] The coating nozzle 414 is connected to the very end of the guide tube 411. It has a flat, slit-like structure with a long rectangular outlet whose width matches the width of the balancing clamp bonding surface. For example... Figure 7 As shown, the flow channel inside the nozzle has a three-section gradient chamber structure, which is divided into a shrinkage section 4140, a diffusion section 4141, and a pressure equalization section 4142 from top to bottom along the dispensing direction. The flow cross-sectional area of the shrinkage section 4140 gradually decreases along the dispensing direction, which gradually accelerates the adhesive entering the nozzle and eliminates uneven flow velocity and turbulence at the inlet. The flow cross-sectional area of the diffusion section 4141 gradually increases along the dispensing direction, which slows down and diffuses the high-speed adhesive, and the pressure gradually becomes uniform along the width direction. The flow cross-sectional area of the pressure equalization section 4142 gradually decreases along the dispensing direction, which is used to stabilize the adhesive pressure and further equalize the adhesive distribution.
[0063] The chamber is symmetrically equipped with multiple flow-diverting ribs 4143 in the center. The spacing between the flow-diverting ribs 4143 gradually increases along the dispensing direction, diverting the faster-flowing adhesive in the central area to both sides. This compensates for the defect of conventional flow channels where the flow rate is high in the center and slow at the edges, resulting in a uniform distribution of adhesive flow rate in the width direction. The flow-diverting ribs 4143 can be set in multiple stages, arranged sequentially along the dispensing direction to form a step-by-step flow-diverting effect, further improving the uniformity of the adhesive.
[0064] Downstream of the flow divider rib 4143, in the pressure equalization section 4142, at least one layer of flow equalization sheet 4144 is provided. The flow equalization sheet 4144 is arranged parallel to the nozzle outlet plane, that is, perpendicular to the thickness direction of the adhesive liquid. The sheet is distributed with dense micro-flow holes, which can further break up the residual turbulence of the adhesive liquid, reduce the flow rate fluctuation, and make the adhesive liquid that finally flows out of the outlet form a strip-shaped adhesive film with uniform thickness and neat edges, which is directly coated on the bonding surface of the balance clamp. The adhesive layer thickness is uniform and consistent, without the defect of being thick in the middle and thin at both ends.
[0065] The nozzle is made of stainless steel or engineering plastic through precision machining, and the inner wall is mirror polished to reduce adhesive adhesion; the outlet width can be customized according to the size of the bonding surface to adapt to different specifications of balance clamp products.
[0066] IV. Finished Product Discharge Mechanism 5 The finished product discharge mechanism 5 adopts a horizontal pushing and feeding structure with magnetic pole repulsion and vertical stacking, which can realize the orderly storage of finished products without collision. It mainly includes a discharge guide platform 50, a discharge push rod 52, a balance clamp storage column 53 and magnetic repulsion components.
[0067] The discharge guide platform 50 is fixedly installed longitudinally on the work platform, located to the left of the longitudinal guide platform 23. A longitudinally extending discharge guide groove 51 is provided inside the discharge guide platform 50. The groove's cross-section matches the contour of the magnetized balance clamp, and its rear end is perpendicularly connected to the transverse guide groove 21. A sliding groove communicating with the transverse guide groove 21 is provided on the rear side of the transverse guide platform 20. The discharge push rod 52 passes through the sliding groove and extends into the transverse guide groove 21, coaxially arranged with the discharge guide groove 51. The discharge drive cylinder is fixed on a support on the rear side of the transverse guide platform 20, driving the discharge push rod 52 to move back and forth, pushing the finished product on the discharge station forward to below the balance clamp storage column 53.
[0068] The balance clamp storage column 53 is vertically installed at the front of the discharge guide table 50. It has a finished product receiving groove 54 that runs vertically through the inside. The groove cross-section is adapted to the contour of the balance clamp after being magnetized. A gap of 0.15~0.25mm is reserved on one side to ensure that the finished products can be smoothly stacked vertically upward along the groove without offset or jamming.
[0069] A magnetic repulsion component is embedded in the discharge guide trough 51 directly below the finished product receiving trough 54. This embodiment uses a permanent magnet solution, which is simple in structure and requires no power supply. The upper surface of the magnetic repulsion component is flush with or slightly lower than the bottom surface of the discharge guide trough 51 by 0.1~0.2mm, which does not affect the horizontal pushing of the workpiece. The upper magnetic pole of the magnetic repulsion component has the same polarity as the lower magnetic pole of the magnet bonded to the balance clamp. Utilizing the physical principle of like poles repelling each other, it generates an upward repulsive force on the finished product above.
[0070] During operation, when the first finished product is pushed directly below the receiving slot, magnetic repulsion lifts it upwards, creating a pushing gap at the bottom of the finished product that is slightly larger than the thickness of a single balancing clamp. When the second finished product is pushed in, it enters horizontally along the gap, simultaneously pushing the first finished product upwards. The second finished product is also under the influence of mutual repulsion, ensuring that the bottom always maintains a gap large enough for the next piece to be pushed in. This process repeats, with finished products being pushed in horizontally in sequence and automatically stacked upwards. No additional power lifting mechanism is required, making the structure simple and reliable. Furthermore, there is no free-falling process throughout the entire process, preventing workpieces from bumping or chipping the magnetic edges. The stacks are neat and orderly, and once full, the workpiece can be removed from the top and directly transferred to the next process.
[0071] If it is necessary to adapt to products of different weights and stacking heights, an electromagnet can be used as a magnetic repulsion component. The magnitude of the repulsion force can be changed by adjusting the working current, making it more adaptable. A diffuse reflection sensor can be installed on the top of the storage column to issue a full material prompt when the stack reaches the set height.
[0072] V. Overall Equipment Workflow The complete processing flow of this equipment is as follows: Material preparation: Before starting the equipment, add the workpieces to the vibrating feeder 1, add the neatly stacked magnets to the magnet storage column 30, connect the air source and glue source, and set the parameters of each station through the control panel.
[0073] Workpiece feeding and conveying: After the equipment is started, the vibrating feeder 1 begins to vibrate and sort the workpieces, and the balance clamps are fed one by one into the front end of the longitudinal guide chute 24; the longitudinal pusher rod 25 extends and pushes the balance clamps backward into the transverse guide chute 21, and then resets. The transverse pusher rod 22 moves to the left and pushes the balance clamps to the glue application station to wait for processing. Simultaneously, the magnetic pusher rod 33 moves to the right and pushes the bottom magnet to the material picking station, and then resets to replenish the material.
[0074] Synchronous operation of gluing and material handling: The cross slide module drives the installation platform 40 to move laterally, so that the glue application head 41 is aligned with the gluing station and the magnetic gripping head 42 is aligned with the material handling station; then the vertical module drives the installation platform 40 to descend to the working height.
[0075] When the on / off control valve 412 is opened, the adhesive enters the coating nozzle 414. After passing through the three-section chamber and the diversion and equalization structure, it is coated onto the surface of the balance clamp in a uniform strip-shaped adhesive film. The slide table drives the coating head to move laterally at a uniform speed to complete the coating of the entire surface. After the coating is completed, the on / off control valve 412 shuts off the air supply, and at the same time, the back suction control valve 413 starts back suction to suck up the residual adhesive at the end of the nozzle and prevent dripping.
[0076] Simultaneously, the electromagnet of the magnetic gripping head 42 is energized, attracting the magnet on the material handling station, and the top plate 424 is compressed by the spring 423 to store energy; after the material handling is completed, the installation platform 40 rises and resets.
[0077] Magnet bonding and pressure holding: The cross slide moves the mounting platform 40 laterally, aligning the magnet gripping head 42 directly above the glued balance clamp; the vertical module moves the mounting platform 40 down to the bonding height, the electromagnet is de-energized and demagnetized, the compression spring 423 rebounds and drives the top plate 424 to force the magnet away from the adsorption surface, flatly bonding it to the adhesive surface; the spring force continues to act to hold pressure for a short time, so that the adhesive layer is evenly spread.
[0078] After the pressure holding is completed, the mounting platform 40 rises and resets, completing the single-piece magnetization process. The horizontal push rod 22 continues to move to the left, pushing the finished product to the discharge station, while the next balance clamp is sent to the glue application station to enter the next processing cycle.
[0079] Finished product stacking and unloading: After the finished product arrives at the unloading station, the unloading pusher 52 extends forward, pushing the finished product along the unloading guide chute 51 to directly below the balance clamp storage column 53; the magnetic repulsion component and the finished product magnet repel each other, lifting the finished product upwards and forming a pushing gap at the bottom. As finished products are continuously pushed in, the stacking height gradually increases, achieving orderly storage; when the material is full, the equipment prompts for manual material removal.
[0080] The overall operation of the equipment is controlled by a programmable logic controller. Each cylinder, solenoid valve, sensor, and slide module is connected to the control system and achieves fully automated operation through preset programs. Processing parameters can be adjusted via a touch screen, which is a conventional technical method in this field and will not be described in detail here.
