Description

TECHNICAL FIELD

[0001] The present application relates to the field of quick connector manufacturing equipment, in particular to a steel ball assembling device. BACKGROUND

[0002] In fluid connection systems, quick-connect fittings are key components that enable quick plugging and disconnection of pipelines without the aid of tools, and are widely used in liquid cooling, hydraulic, pneumatic and industrial automation fields. Currently, the mainstream mechanical quick-connect fittings generally adopt a single-row steel ball structure. However, due to the lack of unified standards in the design and manufacturing process of different manufacturers, the steel ball intake amount often does not match when cross-brand docking occurs.

[0003] In recent years, to improve compatibility and locking stability, a quick-connect fitting design using double-row steel balls has emerged. This scheme sets two circles of steel balls at different axial positions in the fitting body, which respectively undertake the main locking and auxiliary positioning functions. By reasonably configuring the diameters, numbers and action sequences of the two circles of steel balls, the adaptability to the size differences of the grooves of different brand mating parts can be effectively enhanced while ensuring sufficient locking strength.

[0004] However, in the actual assembly process of double-row steel ball quick-connect fittings, the existing technology still has obvious deficiencies. The current assembly process generally follows the traditional method suitable for single-specification steel balls, i.e., independent feeding, positioning and assembly mechanisms are configured for steel balls of different diameters, usually requiring step-by-step operation, or even relying on multiple devices to complete sequentially. This serial operation mode not only has a complicated process and a long cycle, resulting in low overall assembly efficiency, but also significantly increases the labor intensity of the operators; at the same time, due to multiple manual interventions or mechanism switching, quality problems such as steel ball assembly position deviation or missing are easily caused, directly affecting the locking performance and sealing reliability of the fitting. More importantly, the existing automated assembly devices mostly customize the guiding channel, limiting structure and driving system for a single size of steel ball, and cannot simultaneously process two different diameters of steel balls at the same station. When the product model is switched, the entire set of key tooling or even the entire machine device often has to be replaced, resulting in long model switching period, high cost, poor flexibility, and difficulty in meeting the current intelligent manufacturing demand of multiple varieties, small batches and fast delivery. SUMMARY

[0005] The application provides a steel ball assembling device, which aims to correspond to two different specifications of steel balls by arranging two rows of independent feeding boxes, discharging assemblies and guide assemblies, so that the assembling of two types of steel balls in double-row steel ball quick connectors is completed synchronously in a single station, and continuous and integrated assembling operation is realized. The design effectively overcomes the problems of complicated process, long rhythm and low efficiency caused by step-by-step operation of multiple devices in the prior art. In addition, the application further cooperates the adjustable discharging assembly with the replaceable guide assembly, so that only partial adjustment or replacement of a small number of modular components is required when switching product models, without replacing the entire set of key tooling or the entire machine device, thereby significantly improving the versatility and production flexibility of the device and meeting the efficient manufacturing needs of multiple varieties and small batches.

[0006] To achieve the above-mentioned purpose, the application adopts the following technical solutions: The application provides a steel ball assembling device for assembling steel balls for double-row steel ball quick connectors, wherein the double-row steel ball quick connector comprises a shell, and the shell is provided with a first radial through hole and a second radial through hole along the axial direction thereof; the assembling device is arranged on a workbench surface, and comprises: A fixing assembly is arranged for fixing the shell; A rotating base is arranged, and the vertical distance from one side of the rotating base facing the fixing assembly to the workbench surface is greater than the vertical distance from one side of the fixing assembly facing the rotating base to the workbench surface; the rotating base can rotate around the axis of the shell; A storage bin is fixed to one side of the rotating base away from the workbench surface, and the storage bin comprises a first bin and a second bin, which are respectively used to accommodate steel balls of the same or different specifications; A discharging assembly is arranged on one side of the storage bin facing the workbench surface, and the discharging assembly is respectively communicated with the first bin and the second bin, and is used to control the discharging action of the first bin and the second bin; A guide assembly is detachably connected to one side of the storage bin facing the workbench surface, and the guide assembly comprises an inlet hole and an outlet hole; the inlet hole is respectively communicated with the discharging assembly corresponding to the first bin and the second bin, and the axis of the outlet hole is coaxial with the axis of the first radial through hole and the second radial through hole.

[0007] In the above embodiment, the application first reserves sufficient assembly space between the shell and the upper feeding structure by setting the rotating base to be higher in height than the fixed assembly, thereby ensuring that the steel balls can be smoothly and accurately introduced into the radial through holes of the shell under the action of gravity; at the same time, the first bin and the second bin are separately arranged in the storage bin for accommodating steel balls of the same or different specifications, and precise control and directional conveying are realized through the independently connected discharge assemblies and guide assemblies, so that steel balls of two specifications can be simultaneously loaded into the corresponding two rows of radial through holes of the shell at the same station, realizing continuous and integrated assembly operation. The design effectively overcomes the problems of complicated process, long rhythm and low efficiency caused by step-by-step operation of multiple devices in the prior art, and avoids the assembly deviation and missing caused by multiple clamping or manual intervention.

[0008] In addition, the guide assembly and the storage bin are connected in a detachable manner, which facilitates quick replacement of the adaptive guide assembly according to different quick connectors, significantly improves the versatility and model changing efficiency of the equipment, effectively solves the problem of replacing the entire key tooling or even the entire machine equipment during product switching in the prior art, and fully meets the demand for high flexibility and high efficiency manufacturing in the multi-variety and small-batch production scene.

[0009] In some embodiments, the assembly device further comprises a machine case, which is arranged on the workbench; The fixed assembly comprises: A lifting mechanism, a fixed end of the lifting mechanism being fixedly connected to a side of the machine case away from the workbench; A locking mechanism, the locking mechanism being detachably connected to a movable end of the lifting mechanism, and the locking mechanism being used for fixing the shell.

[0010] In the above embodiment, the application sets the lifting mechanism connected with the machine case, and detachably installs the locking mechanism at the movable end of the lifting mechanism, so that the fixed assembly has a vertical lifting function, can lift the shell to a working height accurately aligned with the guide assembly before assembly, ensures that the steel balls are smoothly loaded into the radial through holes, and can lower the shell after assembly to facilitate removal, thereby significantly improving the convenience and operation efficiency of feeding and discharging. At the same time, the locking mechanism and the lifting mechanism are connected in a detachable manner, which facilitates quick replacement of the adaptive locking mechanism according to different double-row steel ball quick connectors, thereby realizing reliable clamping and positioning of shells with different external dimensions or structural characteristics, enhancing the versatility of the equipment, avoiding assembly deviation or damage caused by unstable clamping, and further improving the assembly quality and production flexibility.

[0011] In some embodiments, the lifting mechanism comprises a piston rod, and a threaded portion is arranged at the end of the piston rod; The locking mechanism comprises a clamping sleeve and a locking nut; the clamping sleeve is threadedly connected to the threaded portion on the side close to the lifting mechanism; the clamping sleeve is provided with a fixing groove for accommodating the shell; the outer diameter of the clamping sleeve continuously increases from one end close to the lifting mechanism to the other end along the axial direction, and the outer wall of the fixing groove is provided with a plurality of through-wall locking grooves at intervals in the circumferential direction. The locking nut is sleeved on the clamping sleeve, and the outer peripheral surface of the clamping sleeve is provided with external threads, and the locking nut is threadedly connected to the clamping sleeve.

[0012] In the above embodiment, the threaded portion is arranged at the end of the piston rod of the lifting mechanism, and the clamping sleeve is directly threadedly connected to the threaded portion, so that the compact and reliable detachable connection between the locking mechanism and the lifting mechanism is realized, and the clamping sleeve suitable for different shells can be quickly replaced. In addition, the clamping sleeve is provided with a fixing groove, which can provide stable and coaxial positioning support for the shell, so that the failure of the steel ball to be introduced due to the radial deviation during assembly is avoided. At the same time, the outer diameter of the clamping sleeve continuously increases along the axial direction, and the through locking grooves are arranged at intervals in the circumferential direction. When the locking nut is tightened, the locking nut is axially pushed along the conical outer wall, so that the petal-shaped structure between the locking grooves is radially contracted, thereby applying uniform clamping force to the shell placed in the fixing groove, realizing self-centering clamping, and effectively improving the clamping precision and reliability. The structure is not only simple and convenient to operate, but also controllable in clamping force, and can adapt to shells within a certain size tolerance, and has universality and clamping stability, thereby providing a reliable positioning basis for high-precision synchronous assembly of double-row steel balls.

[0013] In some embodiments, the assembly device comprises a fixed base, and the fixed base comprises: a plurality of first support rods, one end of each first support rod being fixedly connected to the side of the cabinet away from the workbench surface; a first fixed plate, the first fixed plate being fixedly connected to the end of the first support rod away from the cabinet; a first opening is formed in the center of the first fixed plate, the first opening being coaxial with the axis of the lifting mechanism; the first fixed plate is provided with a first annular platform, the first annular platform being arranged along the edge of the first opening.

[0014] In the above embodiment, the fixed base composed of the first support rod and the first fixed plate is arranged, the first fixed plate is stably supported above the cabinet, and the first opening coaxial with the axis of the lifting mechanism is formed in the center of the first fixed plate, thereby providing an accurate axial guide reference for the lifting movement and assembly process of the shell; at the same time, the first annular platform arranged on the first fixed plate is arranged along the edge of the first opening, thereby providing a stable fitting and supporting interface for the subsequent rotating base or related rotating components, and ensuring that the rotating base or related rotating components run stably and do not deviate when rotating around the axis of the lifting mechanism.

[0015] In some embodiments, the fixed base further comprises a second fixed plate, a driving motor and at least three limit bearings; the second fixed plate is fixed to one side of the first fixed plate facing the cabinet through a second support rod; the output shaft of the driving motor is connected with a driving gear; the inner ring of the limit bearing is fixed to one side of the first annular platform facing the cabinet, and the limit bearings are uniformly distributed along the circumference of the first annular platform; The rotating base comprises a second annular platform, an annular bottom plate, a circular tube and a gear ring; a second opening is formed in the center of the second annular platform, the outer edge of the annular bottom plate is connected with the edge of the second opening, and one side of the annular bottom plate facing the cabinet is attached to one side of the first annular platform away from the cabinet; one end of the circular tube is connected with the inner edge of the annular bottom plate, the circular tube passes through the first opening, and the outer ring of the limit bearing is tightly attached to the outer side of the circular tube; the gear ring is sleeved on the circular tube and located between the first annular platform and the cabinet; the driving gear of the driving motor is engaged with the gear ring to drive the rotating base to rotate around the shell axis.

[0016] In the above embodiments, by arranging the second fixed plate, the driving motor and at least three limit bearings uniformly distributed along the circumference in the fixed base, and passing the circular tube of the rotating base through the first opening so that its outer side is tightly attached to the outer ring of each limit bearing, the rotating base is formed with multi-point support and radial constraint in the circumferential direction, effectively inhibiting the shaking and eccentricity during rotation, and ensuring its smooth rotation around the shell axis. At the same time, the driving motor is engaged with the gear ring sleeved on the circular tube through the driving gear, realizing reliable driving of the rotating base, compact structure and stable transmission. In addition, the annular bottom plate is attached to the first annular platform, further improving the axial positioning accuracy and overall rigidity of the rotating base. This design not only ensures the accurate positioning of each station during the rotation of the storage bin, providing a stable motion platform for the synchronous assembly of double-row steel balls, but also significantly improves the reliability and repeatability of the device, meeting the process requirements of high rhythm and high consistency assembly.

[0017] In some embodiments, the assembly device comprises a feeding box for accommodating steel balls; a plurality of sliding rails are arranged on the outer side of the feeding box, and a throat communicating the inside and outside is arranged on one side of the feeding box facing the workbench surface; The storage bin comprises a cylindrical wall and a dust cover; a bottom plate is arranged at one end of the cylindrical wall close to the workbench surface, a partition is arranged in the inner cavity of the cylindrical wall, and the partition divides the inner cavity of the cylindrical wall into a first bin and a second bin on both sides thereof; the dust cover is symmetrically arranged on both sides of the partition to close the first bin and the second bin; The inner side of the cylinder wall is provided with a first sliding groove, and the partition is provided with a second sliding groove. The slide rail of the feeding box is respectively embedded in the first sliding groove and the second sliding groove, so that the feeding box can be inserted into the first compartment or the second compartment along the first sliding groove and the second sliding groove.

[0018] In the above embodiments, this application provides a feeding box with a slide rail, and configures a first slide groove and a second slide groove that cooperate with it on the cylinder wall and partition of the storage bin, respectively. This allows the feeding box to be quickly and accurately inserted into the first or second bin, enabling convenient replenishment of steel balls. During production, operators can prepare multiple feeding boxes filled with steel balls in advance. When the steel balls in a bin are exhausted, simply remove the empty box and insert the full box to replenish the material. The downtime for refueling is short, significantly reducing waiting time and improving the cycle time and efficiency of continuous production. Furthermore, to address the differences in throat diameter, length, and other parameters required for different specifications of steel balls, the feeding box can be replaced to quickly adapt to the assembly requirements of different models of double-row steel ball quick connectors, avoiding complex adjustments or re-tuning of the entire feeding system. This design not only improves the flexibility of equipment changeover and material replenishment efficiency but also enhances the adaptability of the entire machine to multi-variety and variable-specification production, effectively supporting efficient and flexible manufacturing scenarios.

[0019] In some embodiments, the discharge assembly includes: The steel ball channel extends through the thickness direction of the bottom plate. The steel ball channel includes a first channel and a second channel. The axis of the first channel is parallel to the axis of the cylinder wall. The first channel is connected to the throat tube, and the second channel is connected to the feed hole. A laser counting mechanism is disposed on the side wall of the first channel and is used to count the steel balls passing through. The first air outlet is located on the side wall of the first channel and is used to spray high-pressure gas to push the steel ball into the second channel. A first driving mechanism, wherein the fixed end of the first driving mechanism is fixed to the base plate; A baffle plate is connected to the movable end of the first drive mechanism. The baffle plate is located at the connection between the first channel and the throat tube. The baffle plate is used to control the opening and closing of the first channel under the drive of the first drive mechanism. The second drive mechanism has its fixed end fixed to the base plate; A top post is connected to the movable end of the second drive mechanism. The top post is inserted into the first channel and is coaxial with the first channel. The top post is used to adjust the vertical distance between the top post and the baffle under the drive of the second drive mechanism.

[0020] In the above embodiment, the application constructs a high-precision and high-reliability single-steel-ball quantitative feeding and anti-stacking control mechanism by integrating a steel ball channel, a laser counting mechanism, a first air outlet, a baffle driven by a first driving mechanism, and a top column driven by a second driving mechanism in the discharge assembly. Specifically, in the initial state, the baffle closes the entrance of the first channel, limiting the steel balls in the throat. When the system starts the feeding process, the second driving mechanism first drives the top column to rise to a preset height, so that the vertical distance between the top end of the top column and the lower side of the baffle is controlled to be between 1.1 and 1.4 times the diameter of the steel ball, and the front end of the top column blocks the entrance of the second channel, thereby forming a height-limited accommodation cavity in the first channel. Then, the first driving mechanism retracts the baffle for a short time to open the entrance of the first channel, and the steel ball enters the accommodation cavity under the action of gravity. After a first preset time, the baffle is quickly ejected to reseal the entrance of the first channel.

[0021] Ideally, only one steel ball completely falls into the accommodation cavity; however, in actual operation, due to factors such as vibration, accumulation, or feeding inertia, a second steel ball occasionally enters the upper part of the first channel. At this time, since the top column has been pre-raised to a limited height, the second steel ball can only partially invade the gap, and its lower part is blocked by the top end of the top column and the first steel ball already in place below, and cannot completely pass through. Therefore, when the baffle is ejected forward to close, the front end surface of the baffle will exert an axial reverse thrust on the second steel ball that fails to completely enter the accommodation cavity, forcing it to return to the inside of the throat along the original path, thereby ensuring that only one complete steel ball is always accommodated between the baffle and the top column. This cooperative action mechanism effectively solves the technical problems of steel ball stacking and multiple ball mispassing that occur in traditional feeding structures during high-speed continuous operation, and fundamentally avoids problems such as jamming, clogging, or misalignment caused by multiple steel balls entering the subsequent channel at the same time.

[0022] After a second preset time, the second driving mechanism drives the top column to fall back, unblocking the entrance of the second channel; at the same time, the first air outlet sprays non-high-pressure gas to push the only remaining steel ball smoothly into the second channel and into the guide assembly through the feeding hole, ensuring a smooth and unobstructed conveying process. Subsequently, after a third preset time, the second driving mechanism drives the top column to rise to the preset height again, preparing for the next feeding cycle. During the third preset time, if the laser counting mechanism detects that the steel ball passes, it will only trigger an effective count, avoiding false positives caused by signal jitter or multiple reflections. This counting signal provides accurate steel ball feeding feedback for the overall control system, thereby realizing closed-loop monitoring and leak detection warning of the assembly quantity.

[0023] In summary, the application not only significantly improves the accuracy, stability and anti-interference ability of steel ball feeding, but also realizes self-adaptive processing of different specifications of steel balls through modular time sequence control, greatly enhances the flexibility and reliability of the equipment in a multi-variety, high-tact production environment, and provides a solid technical guarantee for high-quality automatic assembly of double-row steel ball quick connectors.

[0024] In some embodiments, a connecting seat is arranged on one side of the bottom plate facing the workbench, and the material guiding assembly is detachably mounted on the connecting seat. A Hall sensor is arranged on the connecting seat, and a magnet is arranged at a corresponding position of the material guiding assembly, and the Hall sensor is used to detect whether the material guiding assembly is installed in place.

[0025] In the above embodiments, the connecting seat is arranged on one side of the bottom plate facing the workbench, and the material guiding assembly is detachably mounted thereon, which facilitates quick replacement of the adaptive material guiding assembly according to different models of double-row steel ball quick connectors, thereby improving the equipment change efficiency. Meanwhile, the Hall sensor is integrated on the connecting seat, and the magnet is arranged at a corresponding position of the material guiding assembly to form a non-contact in-place detection mechanism. When the material guiding assembly is correctly installed in place, the magnet is aligned with the Hall sensor, triggering an induction signal, and the control system confirms that the material guiding assembly has been reliably positioned, and the assembly process can be started. This design effectively avoids the misplacement, jamming or even equipment failure of steel balls caused by the material guiding assembly not being installed, not being installed in place or being loose, thereby improving the operation safety and assembly reliability, and realizing automatic verification before assembly, which provides an important guarantee for full-process automation and error-proof control.

[0026] In some embodiments, the material guiding assembly comprises a material guiding shell, a first sealing cover, a second sealing cover and a material guiding pipe. The material guiding shell is a hollow structure, and the first sealing cover and the second sealing cover are respectively arranged at two ends of the material guiding shell; the feeding hole is arranged on the first sealing cover, and the discharging hole is arranged on the second sealing cover. The material guiding pipe is arranged in the material guiding shell, one end of the material guiding pipe communicates with the feeding hole, and the other end of the material guiding pipe communicates with the discharging hole; an air cavity is formed between the material guiding shell and the material guiding pipe, a pipe insertion hole is arranged on the side wall of the material guiding shell, and a pipe insertion hole is arranged on the connecting seat, the pipe insertion hole is inserted into the pipe insertion hole; a plurality of air injection holes are arranged on the side wall of the material guiding pipe, the direction of the air flow injected from the air injection hole is an acute angle with the discharging direction of the steel balls, and the air injection hole is used to push the steel balls to move along the material guiding pipe by high-pressure gas.

[0027] In the above embodiment, the application sets a guide shell, a guide pipe and an air cavity between the two in the guide assembly, and opens a jet port with an acute angle to the steel ball discharge direction on the side wall of the guide pipe, thereby constructing an internal pneumatic boosting structure, effectively solving the jamming problem of steel balls caused by friction, surface roughness or small foreign matters during the guiding process. Specifically, high-pressure gas enters the spigot of the connecting seat after entering the spigot of the connecting seat, flows into the air cavity between the guide shell and the guide pipe, and is sprayed to the surface of the steel ball in an inclined direction through the jet port, thereby forming an axial thrust component of the guide pipe to continuously push the steel ball to move smoothly. Since the direction of the airflow is acute to the direction of the steel ball movement, the rebound or jumping caused by the positive impact is avoided, and stable and continuous propulsion is provided, thereby significantly improving the conveying reliability. At the same time, the guide assembly as a whole adopts a sealed structure, with the first sealing cover and the second sealing cover closing the two ends of the guide shell, so as to ensure the stability of the air cavity pressure and prevent air leakage from causing insufficient thrust. The cooperation of the spigot and the connecting seat not only realizes the quick connection of the air path, but also facilitates the overall disassembly and maintenance of the guide assembly. The design utilizes air pressure to push the steel ball without increasing external driving mechanisms, effectively prevents the jamming and blocking of the steel ball, ensures the assembly rhythm and yield, and is especially suitable for high-precision and high-speed double-row steel ball synchronous assembly scenarios.

[0028] In some embodiments, the storage bin is provided with a guide pipe in the axial direction; The assembly device further comprises a gas guide assembly, which comprises: An air inlet pipe is inserted into the guide pipe, one end of the air inlet pipe extends out of the guide pipe and is connected with a connector, and the connector is used to connect a high-pressure gas source; An adapter pipe is fixed to the bottom plate, and the end of the air inlet pipe away from the connector is rotationally connected with the adapter pipe through a rotary joint, and the adapter pipe is in communication with the spigot and the first air outlet, respectively.

[0029] In the above embodiment, the application effectively solves the problem of continuous and stable supply of high-pressure gas during the rotation of the storage bin by arranging a guide pipe along the axial direction of the storage bin and configuring a gas guide assembly including an air inlet pipe, a rotary joint, and an adapter pipe. Specifically, the air inlet pipe is a fixed component, with one end connected to an external high-pressure gas source and the other end connected to the adapter pipe that rotates synchronously with the storage bin through the rotary joint; the adapter pipe is fixed to the bottom plate of the storage bin and communicates with the jack and the first air outlet, respectively. This structure uses the rotary joint to achieve dynamic sealing connection between the static gas source and the rotating gas path, ensuring that high-pressure gas is delivered without leakage or interruption to the air cavity of the guide component and the first air outlet during continuous rotation of the storage bin around the shell axis. Thus, not only is the stable pneumatic driving of the steel balls during the entire process of discharging, pushing, and guiding ensured, but also the reliability and automation level of the equipment under high-speed and continuous operation are significantly improved, providing reliable dynamic gas supply protection for high-precision and high-efficiency assembly of double-row steel ball quick connectors.

[0033] In this application, unless specifically stated and limited otherwise, a first feature "on" or "under" a second feature can be directly in contact with the second feature, or indirectly in contact with the second feature through an intermediate medium. Also, a first feature "over", "above" and "on top of" a second feature can be directly above or obliquely above the second feature, or simply means that the first feature is higher in horizontal level than the second feature. A first feature "under", "below" and "underneath" a second feature can be directly below or obliquely below the second feature, or simply means that the first feature is lower in horizontal level than the second feature.

[0034] In this application, the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" mean that a particular feature, structure, material, or characteristic is included in at least one embodiment or example of the present application. Exemplary expressions of the above terms do not necessarily refer to the same embodiment or example in this specification, and the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in one or more embodiments or examples. In addition, those skilled in the art can combine and combine different embodiments or examples described in the specification and the features of different embodiments or examples, without contradiction.

[0035] In the following, the present application will be specifically described by exemplary embodiments. However, it should be understood that the elements, structures and features in one embodiment can also be beneficially combined into other embodiments without further description.

[0036] In the fluid connection system, the quick connector is a key element that can realize the quick plugging and disconnection of the pipeline without the aid of tools, and is widely used in liquid cooling, hydraulic, pneumatic and industrial automation fields. At present, the mainstream mechanical quick connector generally adopts single row steel ball structure, specifically, a circle of steel balls with the same specification are uniformly distributed on the inner circumferential side of the connector body; when the connector and the plug are docked, the plug is inserted into the connector, the steel balls slide into the annular groove on the outer wall of the plug, and the radial restraint force is provided by the sliding sleeve, so as to realize the axial locking. However, this structure is highly sensitive to the geometric parameters (such as depth, taper angle, round angle and tolerance) of the plug groove. Due to the lack of unified standards in the design and manufacturing process of different manufacturers, the mismatching of steel ball intake often occurs when cross-brand docking. If the intake is too shallow, the locking force is insufficient, and it is easy to be disconnected under vibration or pressure impact; if the intake is too deep, the plugging resistance increases dramatically, and even causes jamming and engagement. In addition, the mismatching of steel ball intake may also cause leakage risk.

[0037] To improve compatibility and locking stability, a double-row steel ball quick connector design has appeared in recent years. This scheme sets two circles of steel balls in different axial positions in the connector body, which respectively bear the main locking and auxiliary positioning functions. For example, large-diameter steel balls are used to provide the main anti-pullout holding force, and small-diameter steel balls are used to guide the centering at the initial plug-in stage, compensate for manufacturing tolerances, or adjust the locking stroke. By reasonably configuring the diameters, numbers, and action sequences of the two circles of steel balls, the adaptability to size differences of grooves of different brands of mating parts can be effectively enhanced while ensuring sufficient locking strength.

[0038] However, in the actual assembly process of the double-row steel ball quick connector, the existing technology still has obvious deficiencies. The current assembly process generally follows the traditional method suitable for single-specification steel balls, that is, independent feeding, positioning, and assembly mechanisms are configured for steel balls of different diameters, which usually requires step-by-step operation or even relies on multiple devices to complete sequentially. This serial operation mode not only has a complicated process and a long cycle, resulting in low overall assembly efficiency, but also significantly increases the labor intensity of the operators. At the same time, due to multiple manual interventions or mechanism switching, quality problems such as steel ball assembly position deviation or missing are easily caused, directly affecting the locking performance and sealing reliability of the connector. More importantly, the existing automatic assembly device is mostly customized for a single size of steel ball in terms of guiding channel, limiting structure, and driving system, and cannot simultaneously process two different diameters of steel balls at the same station. When the product model is switched, the entire set of key tooling or even the entire machine device often has to be replaced, resulting in long model switching period, high cost, poor flexibility, and difficulty in meeting the current intelligent manufacturing demand of multiple varieties, small batches, and fast delivery.

[0039] Based on this, the present application provides a steel ball assembly device, which aims to simultaneously complete the assembly of two types of steel balls in a double-row steel ball quick connector at a single station by setting two independent feeding boxes 600, discharging assemblies 590, and guide assemblies 700 corresponding to two different specifications of steel balls, thereby realizing continuous and integrated assembly operation. This design effectively overcomes the problems of complicated process, long cycle, and low efficiency caused by relying on multiple devices for step-by-step operation in the existing technology. In addition, the present application further cooperates with the adjustable discharging assembly 590 and the replaceable guide assembly 700 to only need to adjust or replace a small number of modular components when switching product models, without replacing the entire set of key tooling or the entire machine device, thereby significantly improving the versatility and production flexibility of the device and meeting the efficient manufacturing demand of multiple varieties and small batches.

[0040] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0041] As shown in FIG. 1, the steel ball assembly device of the present application comprises a feeding box 600, a discharging assembly 590, a guide assembly 700, and a driving assembly 800. Figures 1 to 19As shown, in one illustrative embodiment of the present application, the assembly device is used to assemble steel balls for a double-row steel ball quick connector. The double-row steel ball quick connector includes a housing and a sliding sleeve, the sliding sleeve is sleeved on the outer periphery of the housing; the housing is provided with two rows of radial through holes along the axial direction thereof, each row of radial through holes includes a plurality of radial through holes distributed along the circumferential direction; wherein each radial through hole in one row is defined as a first radial through hole, and each radial through hole in the other row is defined as a second radial through hole.

[0042] Specifically, the double-row steel ball quick connector includes a housing and a sliding sleeve sleeved on the outer periphery of the housing. The housing is provided with two rows of radial through holes along the axial direction thereof; each row of radial through holes is uniformly distributed along the same circumferential circumference of the housing, and each row includes a plurality of radial through holes, and the two rows of radial through holes are used to assemble steel balls of different specifications or the same specification, and the diameters and numbers of the two rows of radial through holes can be set to be the same or different according to design requirements. The sliding sleeve is an annular part that can slide along the axial direction of the housing, and is the core executive component for realizing the "locking-unlocking" function. The inner wall structure of the sliding sleeve cooperates with the grooves of the steel balls and the plug: in the locking position, the inner tapered surface of the sliding sleeve pushes each ring of steel balls radially inward, so that the steel balls partially protrude from the inner wall of the housing and are embedded in the corresponding annular groove of the plug, thereby completing mechanical locking. In the unlocking position, the sliding sleeve slides backward, and the inner diameter of the corresponding steel ball region expands to form a cavity, so that the steel balls can retreat outward, facilitating disengagement from the plug groove, thereby allowing the plug to be smoothly pulled out. This structure precisely controls the locking and release of the steel balls through the axial movement of the sliding sleeve, ensuring reliable and safe operation of the connector 581a. In addition, since the double-row steel ball quick connector belongs to the category of prior art, its specific structural details will not be described in detail herein.

[0043] In some embodiments, the assembly device is provided on a workbench, which can be the ground or other types of tabletops.

[0044] It should be particularly pointed out that in this paper, the side of the assembly device close to the workbench is defined as the "down" direction, and the side away from the workbench is defined as the "up" direction, and this definition is uniform throughout the paper, and will not be repeated in the subsequent description.

[0045] In some embodiments, the assembly device includes a fixing assembly 200 for fixing the housing to facilitate subsequent assembly of steel balls for the housing.

[0046] In some embodiments, the assembly device includes a rotating base 400, the vertical distance from the side of the rotating base 400 facing the fixing assembly 200 to the workbench is greater than the vertical distance from the side of the fixing assembly 200 facing the rotating base 400 to the workbench; that is, the fixing assembly 200 is located above the workbench, and the rotating base 400 is located above the fixing assembly 200. In addition, the rotating base 400 can rotate around the axis of the housing.

[0047] In some embodiments, the assembly device comprises a storage bin 500 fixed to the side of the rotating base 400 away from the workbench, i.e. the storage bin 500 is located above the rotating base 400; the storage bin 500 comprises a first bin 550 and a second bin 560, which are respectively used to accommodate steel balls of the same or different specifications.

[0048] In some embodiments, the assembly device comprises a discharge assembly 590, which has two groups in total, and is arranged on the side of the storage bin 500 facing the workbench. The two groups of discharge assemblies 590 are respectively in communication with the first bin 550 and the second bin 560, and are respectively used to control the discharging action of the first bin 550 and the second bin 560.

[0049] In some embodiments, the assembly device comprises a guide assembly 700, which has two groups in total, and is detachably connected to the side of the storage bin 500 facing the workbench. The guide assembly 700 comprises an inlet hole 711a and an outlet hole 712a. The inlet hole 711a is respectively in communication with the discharge assembly 590 corresponding to the first bin 550 and the second bin 560, and the axis of the outlet hole 712a is coaxial with the axis of the first radial through hole and the second radial through hole.

[0050] Specifically, the inlet hole 711a of one group of guide assemblies 700 is in communication with the discharge assembly 590 corresponding to the first bin 550, and the axis of the outlet hole 712a thereof is coaxial with the axis of the first radial through hole; the inlet hole 711a of the other group of guide assemblies 700 is in communication with the discharge assembly 590 corresponding to the second bin 560, and the axis of the outlet hole 712a thereof is coaxial with the axis of the second radial through hole.

[0051] In the above embodiments, the rotating base 400 is first arranged to be higher in height than the fixed assembly 200, thereby reserving sufficient assembly space between the housing and the upper feeding structure, ensuring that the steel balls can be smoothly and accurately guided into the radial through holes of the housing under the action of gravity; at the same time, the first bin 550 and the second bin 560 are separately arranged in the storage bin 500, and are respectively used to accommodate steel balls of the same or different specifications, and precise control and directional conveying are realized through the discharge assemblies 590 and the guide assemblies 700 which are independently communicated, so that steel balls of two specifications can be simultaneously loaded into the corresponding two rows of radial through holes of the housing at the same station, realizing continuous and integrated assembly operation. This design effectively overcomes the problems of complicated process, long rhythm and low efficiency caused by relying on multiple devices for step-by-step operation in the prior art, and avoids the assembly deviation and missing risk caused by multiple clamping or manual intervention.

[0052] In addition, the material guiding assembly 700 is detachably connected with the material storage bin 500, so that the material guiding assembly 700 suitable for different types of quick connectors can be quickly replaced to adapt to steel balls of different specifications, thereby significantly improving the universality and model changing efficiency of the equipment, effectively solving the problem of the prior art that the entire key tooling or even the entire machine equipment needs to be replaced when the product is switched, and fully meeting the demand for high flexibility and high efficiency manufacturing in the multi-variety and small-batch production scene.

[0053] In some embodiments, the assembling device further comprises a cabinet 100 arranged on the workbench.

[0054] In some embodiments, the cabinet 100 is provided with a control module, and the control module comprises a control chip, a memory, a wireless communication module and a matching control circuit; wherein the memory stores a control method for coordinating the operation of each component of the device. It should be noted that the hardware composition (including the control chip, the memory, the communication module and the control circuit) of the above-mentioned control module and the control system (including control logic, signal processing and execution instructions) adopted all belong to the prior art, and a general industrial controller, PLC or embedded system can be used for implementation. For those skilled in the art, after combining the description of the structure and function of the present application in this paper, it is obvious that the specific selection, configuration and control method programming of the control module can be implemented without creative labor, and therefore the specific implementation details and principles will not be described again.

[0055] In some embodiments, the side of the cabinet 100 is provided with a display screen 110 and a plurality of control buttons 120, and the display screen 110 and the control buttons 120 are electrically connected with the control chip in the control module; the staff inputs control parameters to the control module by operating the control buttons 120, and starts, stops or adjusts each operation action of the device, and at the same time, the staff can real-time check the equipment state, operation parameters and operation feedback information through the display screen 110.

[0056] In some embodiments, the side of the cabinet 100 facing the workbench is provided with a plurality of shock-absorbing pads 130.

[0057] In some embodiments, the fixing assembly 200 comprises a lifting mechanism 210, and the fixed end of the lifting mechanism 210 is fixedly connected with the side of the cabinet 100 away from the workbench. Wherein, the axis of the lifting mechanism 210 is coaxial with the axis of the fixed shell.

[0058] In some embodiments, the fixing assembly 200 comprises a locking mechanism 220, and the locking mechanism 220 is detachably connected with the movable end of the lifting mechanism 210, and the locking mechanism 220 is used for fixing the shell.

[0059] It should be noted that the axis of the discharge hole 712a of the group of material guiding assemblies 700 is coaxial with the axis of the first radial through hole or the second radial through hole on the shell, which means that after the shell is placed in the locking mechanism 220 and is preliminarily fixed by the locking mechanism 220, the lifting mechanism 210 drives the locking mechanism 220 to rise to a preset position; then, the operator manually rotates the shell to align the discharge hole 712a of the group of material guiding assemblies 700 with a through hole in a certain row of radial through holes on the shell, so as to realize the coaxial alignment. Considering that the two rows of radial through holes on the shell can be arranged in a staggered manner, in order to ensure the assembly precision and functional matching, the structure and shape of the two groups of material guiding assemblies 700 are optimized in the design stage, so that when the discharge hole 712a of one group of material guiding assemblies 700 is coaxial with a through hole (first radial through hole) in the first row of radial through holes, the discharge hole 712a of the other group of material guiding assemblies 700 can also be coaxial with a corresponding through hole (second radial through hole) in the second row of radial through holes, so as to ensure that the material can smoothly and accurately pass through the entire material guiding channel.

[0060] In the above embodiment, the lifting mechanism 210 connected with the case 100 is arranged, and the locking mechanism 220 is detachably installed at the movable end of the lifting mechanism 210, so that the fixing assembly 200 has a vertical lifting function, can lift the shell to a working height for accurate alignment with the material guiding assembly 700 before assembly, ensures that the steel balls are smoothly loaded into the radial through hole, and can lower the shell after assembly for easy removal, which significantly improves the convenience and operation efficiency of the feeding and discharging. At the same time, the locking mechanism 220 and the lifting mechanism 210 are detachably connected, which facilitates quick replacement of the locking mechanism 220 suitable for different models of double-row steel balls, so as to realize reliable clamping and positioning of shells with different external dimensions or structural characteristics, which not only enhances the universality of the equipment, but also avoids assembly deviation or damage caused by unstable clamping, and further improves the assembly quality and production flexibility.

[0061] In some embodiments, the lifting mechanism 210 includes a piston rod 211, and a threaded portion 211a is arranged at the end of the piston rod 211.

[0062] Further, the lifting mechanism 210 is a gas cylinder.

[0063] In some embodiments, the locking mechanism 220 comprises a clamping sleeve 221 and a locking nut 222; the clamping sleeve 221 is threadedly connected to the threaded portion 211a near one side of the lifting mechanism 210; the clamping sleeve 221 is provided with a fixed groove 221b for accommodating the shell; the outer diameter of the clamping sleeve 221 continuously increases along the axial direction from one end near the lifting mechanism 210 to the other end; the outer wall of the fixed groove 221b is provided with a plurality of through-wall locking grooves 221a at intervals in the circumferential direction; wherein the locking grooves 221a serve to provide space for the inward contraction of the clamping sleeve 221 when the locking nut 222 is rotated upward.

[0064] The locking nut 222 is sleeved on the clamping sleeve 221, the outer peripheral surface of the clamping sleeve 221 is provided with external threads, and the locking nut 222 is threadedly connected with the clamping sleeve 221.

[0065] In some embodiments, the fixed groove 221b has a constant diameter along the axial direction.

[0066] In the above embodiments, by providing a threaded portion 211a at the end of the piston rod 211 of the lifting mechanism 210 and directly threadedly connecting the clamping sleeve 221 with the threaded portion 211a, a compact and reliable detachable connection between the locking mechanism 220 and the lifting mechanism 210 is achieved, which facilitates quick replacement of the clamping sleeve 221 adapted to different shells. In addition, the clamping sleeve 221 is provided with a fixed groove 221b inside, which can provide stable and coaxial positioning support for the shell. After the shell is fixed, the shell is coaxial with the lifting mechanism 210, avoiding the failure of steel ball introduction due to radial deviation during assembly. At the same time, the outer diameter of the clamping sleeve 221 continuously increases along the axial direction, and is matched with the through locking grooves 221a arranged at intervals in the circumferential direction. When the locking nut 222 is tightened, the locking nut 222 is axially pushed along the tapered outer wall, causing the petal-shaped structure between the locking grooves 221a to contract radially, thereby exerting uniform clamping force on the shell placed in the fixed groove 221b, achieving self-centering clamping, and effectively improving clamping precision and reliability. This structure not only has simple operation and controllable clamping force, but also can adapt to shells within a certain size tolerance range, taking into account universality and clamping stability, and providing a reliable positioning basis for high-precision synchronous assembly of double-row steel balls.

[0067] In some embodiments, the assembly device comprises a fixed base 300, and the fixed base 300 comprises a plurality of first support rods 310, one end of each first support rod 310 being fixedly connected to the side of the case 100 away from the workbench surface.

[0068] Further, the number of first support rods 310 is three, and the first support rods 310 are located on the same circumference, and the three first support rods 310 are evenly arranged on the circumference.

[0069] In some embodiments, the assembling device comprises a first fixed plate 320, which is fixedly connected with one end of the first support rod 310 away from the cabinet 100, i.e. the first fixed plate 320 is located above the cabinet 100; the first fixed plate 320 is provided with a first opening 321 at the center thereof, which is coaxial with the axis of the lifting mechanism 210; and the first fixed plate 320 is provided with a first annular platform 322, which is arranged along the edge of the first opening 321.

[0070] Further, the vertical distance from the upper surface of the first annular platform 322 to the workbench is less than the vertical distance from the upper surface of the first fixed plate 320 to the workbench.

[0071] In the above embodiments, the fixed base 300 composed of the first support rod 310 and the first fixed plate 320 is provided to stably support the first fixed plate 320 above the cabinet 100 and to provide the first opening 321 coaxial with the axis of the lifting mechanism 210 at the center thereof, thereby providing an accurate axial guide reference for the lifting movement and the assembling process of the shell; at the same time, the first annular platform 322 arranged along the edge of the first opening 321 on the first fixed plate 320 provides a stable fitting and supporting interface for the subsequent rotating base 400 or related rotating components, thereby ensuring smooth operation and no deflection when rotating around the axis of the lifting mechanism 210.

[0072] In some embodiments, the fixed base 300 further comprises a second fixed plate 330, a driving motor 332 and at least three limit bearings 340; the second fixed plate 330 is fixed to the side of the first fixed plate 320 facing the cabinet 100 through a second support rod 331, i.e. the second fixed plate 330 is located below the first fixed plate 320; the driving motor 332 is fixed on the second fixed plate 330, and the output shaft of the driving motor 332 is connected with a driving gear 332a; the inner ring of the limit bearing 340 is fixedly connected with the side of the first annular platform 322 facing the cabinet 100, and the limit bearings 340 are uniformly distributed along the circumference of the first annular platform 322.

[0073] In some embodiments, the rotating base 400 comprises a second annular platform 410, an annular bottom plate 420, a circular tube 430, and a gear ring 440; the second annular platform 410 is provided with a second opening 450 in the center, and a gap is arranged between the second annular platform 410 and the first fixed plate 320; the outer edge of the annular bottom plate 420 is connected to the edge of the second opening 450, the outer diameter of the annular bottom plate 420 is less than or equal to the outer diameter of the first annular platform 322, the side of the annular bottom plate 420 facing the cabinet 100 is attached to the side of the first annular platform 322 away from the cabinet 100, and grease is arranged between the annular bottom plate 420 and the first annular platform 322 to reduce friction; the outer diameter of the circular tube 430 is less than the inner diameter of the first annular platform 322, one end of the circular tube 430 is connected to the inner edge of the annular bottom plate 420, the circular tube 430 passes through the first opening 321, the outer ring of the limiting bearing 340 is tightly attached to the outer side of the circular tube 430, and the limiting bearing 340 is used to constrain the rotating base 400 to avoid the rotating base 400 from moving in the first opening 321; the gear ring 440 is sleeved on the circular tube 430 and located between the first annular platform 322 and the cabinet 100; the driving gear 332a of the driving motor 332 is engaged with the gear ring 440 to drive the rotating base 400 to rotate around the housing axis.

[0074] In the above embodiments, by arranging the second fixed plate 330, the driving motor 332, and at least three limiting bearings 340 uniformly distributed in the circumferential direction in the fixed base 300, and passing the circular tube 430 of the rotating base 400 through the first opening 321 so that its outer side is tightly attached to the outer ring of each limiting bearing 340, the rotating base 400 is formed with multi-point support and radial constraint in the circumferential direction, effectively inhibiting shaking and eccentricity during rotation, and ensuring smooth rotation around the housing axis. At the same time, the driving motor 332 is engaged with the gear ring 440 sleeved on the circular tube 430 through the driving gear 332a to realize reliable driving of the rotating base 400, with compact structure and stable transmission. In addition, the annular bottom plate 420 is attached to the first annular platform 322, further improving the axial positioning accuracy and overall rigidity of the rotating base 400. This design not only ensures the accurate positioning of each station of the storage bin 500 during rotation, providing a stable motion platform for synchronous assembly of double-row steel balls, but also significantly improves the reliability and repeatability of the device, meeting the process requirements of high rhythm and high consistency assembly.

[0075] In some embodiments, the assembly device comprises two feeding boxes 600 for containing steel balls; a plurality of sliding rails 610 are arranged on the outer side of the feeding box 600, and a throat pipe 620 is arranged on the side of the feeding box 600 facing the workbench to communicate the inside and the outside.

[0076] Further, the throat pipe 620 is arranged at the lowest position of the feeding box 600, so as to facilitate the steel balls to enter the throat pipe 620 under the action of gravity.

[0077] Further, the throat pipe 620 is sized according to the diameter of the steel balls, and the diameter of the throat pipe 620 is slightly larger than the diameter of the steel balls, and the length of the throat pipe 620 is within the range of 1 to 1.2 times the diameter of the steel balls, so as to avoid the occurrence of jamming and reduce the risk of simultaneous discharge of multiple steel balls.

[0078] Further, the top of the feeding box 600 is provided with a carrying strap or a carrying rope, so as to facilitate the taking out or preventing the feeding box 600.

[0079] That is to say, in order to adapt to different specifications of steel balls, the present application needs to be equipped with multiple sets of feeding boxes 600 with different sizes of throat pipes 620.

[0080] In some embodiments, the storage bin 500 is fixedly connected to the second annular platform 410 through a plurality of columns.

[0081] In some embodiments, the column is fixedly connected to the second annular platform 410 through a bolt.

[0082] Further, the number of columns is three, and the columns are evenly distributed around the circumference of the second annular platform 410.

[0083] In some embodiments, the storage bin 500 includes a cylindrical wall 510 and two dust covers 570. The cylindrical wall 510 is provided with a bottom plate 520 at one end close to the workbench surface. The inner cavity of the cylindrical wall 510 is provided with a partition plate 530 extending along the radial direction of the cylindrical wall 510. The partition plate 530 divides the inner cavity of the cylindrical wall 510 into a first bin 550 and a second bin 560 located on both sides of the partition plate 530. The first bin 550 and the second bin 560 are both used to accommodate the feeding box 600. The two dust covers 570 are symmetrically arranged on both sides of the partition plate 530 and are used to close the first bin 550 and the second bin 560.

[0084] Further, the two dust covers 570 are detachably connected through the cooperation of the clamping block and the clamping groove, and the dust cover 570 and the cylindrical wall 510 are detachably connected through the buckle structure. Since the clamping block, the clamping groove and the buckle structure are all prior art, the specific technical details are not described in detail.

[0085] Further, the height of the feeding box 600 is consistent with the height of the first bin 550 and the second bin 560. In this way, when the feeding box 600 is inserted into the first bin 550 and the second bin 560, the dust cover 570 can limit the feeding box 600 to prevent the feeding box 600 from moving axially.

[0086] In some embodiments, the inner side of the barrel wall 510 is provided with a first sliding groove 511, the partition plate 530 is provided with a second sliding groove 531, and the sliding rails 610 of the feeding box 600 are respectively embedded in the first sliding groove 511 and the second sliding groove 531 to form a constraint and limiting, so that the feeding box 600 can be inserted into the first bin 550 or the second bin 560 along the first sliding groove 511 and the second sliding groove 531.

[0087] In the above embodiments, the feeding box 600 with the sliding rails 610 is provided, and the first sliding groove 511 and the second sliding groove 531 matched with the feeding box 600 are respectively arranged on the barrel wall 510 and the partition plate 530 of the storage bin 500, so that the feeding box 600 can be quickly and accurately inserted into the first bin 550 or the second bin 560, and the steel balls can be conveniently supplemented. In the production process, the operator can prepare a plurality of feeding boxes 600 filled with steel balls in advance. When the steel balls in a bin are consumed, the empty box is only needed to be pulled out and the full box is only needed to be inserted to complete the feeding, the downtime for feeding is short, the waiting time is significantly shortened, and the rhythm and efficiency of continuous production are improved. At the same time, according to the differences in the diameter and length of the throat pipe 620 and other parameters required by different specifications of steel balls, the feeding box 600 matched can be replaced to quickly adapt to the assembly requirements of different models of double-row steel ball quick connectors, and complex adjustment or re-commissioning of the whole feeding system is avoided. The design not only improves the flexibility of equipment change and the efficiency of material supplement, but also enhances the adaptability of the whole machine to multi-variety and variable-specification production, effectively supporting efficient and flexible manufacturing scenarios.

[0088] In some embodiments, the discharging assembly 590 includes a steel ball channel penetrating through the thickness direction of the bottom plate 520, and the steel ball channel includes a first channel 591 and a second channel 592. The axis of the first channel 591 is parallel to the axis of the barrel wall 510, the first channel 591 is in communication with the throat pipe 620, and the second channel 592 is in communication with the feeding hole 711a.

[0089] Further, the first channel 591 is arranged in a vertical direction, and the inlet of the first channel 591 is in communication with the throat pipe 620. The second channel 592 extends obliquely downward from the connection with the first channel 591, and then extends vertically downward. The outlet of the second channel 592 is in communication with the feeding hole 711a. The inlet of the second channel 592 is arranged on the side wall of the first channel 591 and is in communication with the inside of the first channel 591. At the connection between the first channel 591 and the second channel 592 and the turning position of the second channel 592, a circular arc transition structure is adopted to reduce the flow resistance of the steel balls when passing through, avoid the jamming or jumping caused by the edges or sudden changes in cross section, and ensure the smooth and reliable conveying of the steel balls.

[0090] Further, the diameters of the first channel 591 and the second channel 592 are equal.

[0091] In some embodiments, the discharging assembly 590 comprises a laser counting mechanism 591a arranged on the sidewall of the first channel 591 for counting the steel balls passing through. Among them, the laser counting device is a conventional structure, which usually comprises a laser emitter and a photosensitive receiver arranged oppositely (or adopts a reflective structure, that is, the laser emission and reception are integrated), which are respectively located on both sides (or the same side) of the first channel 591; when the steel ball passes through the first channel 591, it will block or reflect the laser beam, thereby triggering a change in the level signal. After amplification and shaping by the signal processing circuit, the signal is sent to the control module for counting. Such laser counting devices have been widely used in the field of industrial automation, and their selection, installation method and signal processing method are common knowledge to those skilled in the art, which can be realized without creative labor.

[0092] In some embodiments, the discharging assembly 590 comprises a first air outlet 591b arranged on the sidewall of the first channel 591; the jet direction of the first air outlet 591b is towards the inlet of the second channel 592, for spraying high-pressure gas to push the steel balls to smoothly slide from the first channel 591 into the second channel 592.

[0093] In some embodiments, the discharging assembly 590 comprises a first driving mechanism 593, and the fixed end of the first driving mechanism 593 is fixed to the bottom plate 520.

[0094] Further, the first driving mechanism 593 can adopt a micro single-acting cylinder, which has compact structure and rapid response, and is suitable for rapid opening and closing control of the blocking piece 593a and other execution components. Specifically, the micro single-acting cylinder is a small-sized pneumatic execution element. When working, compressed air enters the cylinder cavity from the self-provided air inlet valve, pushes the piston to move axially along the cylinder barrel, so that the piston rod 211 extends to complete the work. When the compressed air is cut off, the piston automatically returns to the initial position under the action of the built-in return spring, and drives the piston rod 211 to retract, thereby realizing the closure of the blocking piece 593a.

[0095] In some embodiments, the outfeed assembly 590 comprises a shutter 593a connected to the movable end of the first driving mechanism 593, which is located at the junction of the first channel 591 and the throat 620, and is used to control the opening and closing of the first channel 591 under the driving of the first driving mechanism 593. In the initial state, the shutter 593a closes the entrance of the first channel 591; when the system starts the feeding process, the shutter 593a is quickly retracted under the driving of the first driving mechanism 593, so that the steel ball can enter the first channel 591. Subsequently, after a first preset time elapses, or when the laser counting mechanism 591a detects that the steel ball has fallen, the shutter 593a is quickly reset and ejected, resealing the entrance of the first channel 591. This process is repeated to achieve controlled feeding of steel balls one by one. The first preset time can be adjusted according to actual working conditions (such as steel ball size, material, feeding speed, etc.), which is not limited in the present application.

[0096] In some embodiments, the outfeed assembly 590 comprises a second driving mechanism 594, the fixed end of which is fixed to the bottom plate 520.

[0097] Further, the second driving mechanism 594 is a micro servo electric push rod. The micro servo electric push rod is an electric actuator that integrates a motor, a transmission mechanism (usually a lead screw or a ball screw) and a position feedback device. Its working principle is: the control signal drives the built-in servo motor to rotate, which drives the lead screw to rotate through the reduction mechanism, and then pushes the nut or push rod to move linearly along the axial direction; at the same time, the built-in position sensor (such as an encoder) feedbacks the push rod displacement information in real time, realizing high-precision position, speed and thrust control.

[0098] In some embodiments, the outfeed assembly 590 comprises a top column 594a connected to the movable end of the second driving mechanism 594, which is inserted into the first channel 591 from the bottom end of the first channel 591 and is coaxial with the first channel 591, and is used to adjust the vertical distance between the top column 594a and the shutter 593a under the driving of the second driving mechanism 594, so as to avoid multiple steel balls entering the first channel 591 at the same time.

[0099] It should be noted that since the inner diameters of the first channel 591 and the second channel 592 are fixed values after manufacturing and cannot be adjusted, there are clear upper and lower limits to the range of steel ball diameters that can be adapted by the same outfeed assembly 590 (i.e., an integrated structure integrated with a specific storage bin 500).

[0100] Specifically, in the design stage, if the minimum steel ball diameter that the discharge assembly 590 is adapted to is d1, the inner diameters of the first channel 591 and the second channel 592 should generally satisfy: not less than 1.1d1 and not greater than 1.7d1, and the specific value should be determined according to the actual situation.

[0101] Suppose that the inner diameter of the first channel 591 is 1.5d1, and the length of the first channel 591 is greater than 1.5d1, then the steel ball diameter range that the discharge assembly 590 is adapted to is d1≤d<1.5d1. At this time, if the steel ball diameter is less than d1, then in the feeding process, even if the top column 594a has risen to the preset height, the second steel ball may still be partially squeezed into the first channel 591 due to the small size; when the baffle 593a is reset and ejected, it cannot effectively push it back into the throat pipe 620, thereby causing multiple balls to enter or be stuck, causing a failure. Conversely, if the steel ball diameter is greater than 1.5d1, the steel ball will not be able to enter the first channel 591 smoothly, causing the feeding to be interrupted.

[0102] Therefore, in the present application, replacing the guide assembly 700 and the feeding box 600 belongs to the fine-tuning measure, which is used to adapt to different steel ball specifications within the allowable range of the same discharge assembly 590; and when the steel ball diameter exceeds the range, the storage bin 500 (including the integrated discharge assembly 590) needs to be replaced as a whole, and the matching guide assembly 700 and the feeding box 600 need to be replaced simultaneously, so as to realize the coverage of a wider specification spectrum. This staged adaptation strategy takes into account the versatility, replacement efficiency and assembly reliability of the equipment.

[0103] In some embodiments, the present application adopts a process of assembling steel balls in stages. Specifically, the discharge assembly 590 controls the release timing of the steel balls: first, assemble the steel balls into the first radial through holes of the first row one by one; and then, after all the first radial through holes are completed with the steel ball assembly, sequentially assemble the steel balls into the second radial through holes of the second row.

[0104] In other embodiments, the present application can also adopt a process of synchronously assembling steel balls, that is, simultaneously assembling steel balls into the radial through holes of the first row and the second row. The specific assembly method can be flexibly selected and adjusted according to factors such as equipment configuration, production efficiency requirements and product structure characteristics.

[0105] It should be noted that in the steel ball assembly process, the driving assembly drives the rotating base to rotate by a preset angle and then stops, so that the radial through hole to be assembled is aligned with the discharge end of the discharge assembly 590, and then the steel ball filling is performed. After completing the assembly of the current round, the rotating base rotates by the same preset angle again, and enters the next round of assembly cycle. The preset angle is determined by the circumferential included angle between the adjacent radial through holes of the shell, so as to ensure that the next through hole is accurately positioned after each rotation, thereby realizing orderly, efficient and precise steel ball assembly.

[0106] In the above embodiment, the application constructs a set of high-precision and high-reliability single-steel-ball quantitative feeding and anti-stacking control mechanism by integrating the steel ball channel, the laser counting mechanism 591a, the first air outlet 591b, the baffle 593a driven by the first driving mechanism 593, and the top column 594a driven by the second driving mechanism 594 in the discharge assembly 590. Specifically, in the initial state, the baffle 593a closes the entrance of the first channel 591, limiting the steel balls in the throat pipe 620; when the system starts the feeding process, the second driving mechanism 594 first drives the top column 594a to rise to a preset height, so that the vertical distance between the top end of the top column 594a and the lower side of the baffle 593a is controlled to be between 1.1 and 1.4 times the diameter of the steel ball, and at the same time, the front end of the top column 594a blocks the entrance of the second channel 592, thereby forming a height-limited accommodation cavity in the first channel 591; then, the first driving mechanism 593 temporarily retracts the baffle 593a to open the entrance of the first channel 591, and the steel ball enters the accommodation cavity under the action of gravity. After a first preset time, the baffle 593a is quickly ejected to reseal the entrance of the first channel 591.

[0107] Ideally, only one steel ball completely falls into the accommodation cavity; but in actual operation, affected by factors such as vibration, accumulation or feeding inertia, occasionally a second steel ball follows into the upper part of the first channel 591. At this time, since the top column 594a has been pre-raised to a limited height, the second steel ball can only partially invade the gap, and its lower part is blocked by the top end of the top column 594a and the first steel ball already in place below, and cannot pass completely. Therefore, when the baffle 593a is ejected forward to close, the front end surface of the baffle 593a will exert an axial reverse thrust on the second steel ball that fails to completely enter the accommodation cavity, forcing it to retreat to the inside of the throat pipe 620 along the original path, thereby ensuring that only one complete steel ball is accommodated between the baffle 593a and the top column 594a. This cooperative action mechanism effectively solves the technical problems of steel ball stacking and multiple-ball mispassing that are prone to occur in traditional feeding structures during high-speed continuous operation, and fundamentally avoids problems such as jamming, clogging or misalignment caused by multiple steel balls entering the subsequent channel at the same time.

[0108] After a second preset time (the second preset time is greater than the first preset time, and the second preset time is determined according to actual conditions), the second driving mechanism 594 drives the top column 594a to fall back, and the blocking of the entrance of the second channel 592 is released; at the same time, the first air outlet 591b sprays non-high-pressure gas to push the only remaining steel ball to smoothly slide into the second channel 592, and then enter the material guide assembly 700 through the feeding hole 711a, ensuring smooth and unobstructed conveying process. Subsequently, after a third preset time (the third preset time is greater than the second preset time, and the third preset time is determined according to actual conditions), the second driving mechanism 594 drives the top column 594a to rise to a preset height again, preparing for the next feeding period. During the third preset time, if the laser counting mechanism 591a detects that the steel ball passes, only one valid count is triggered, avoiding false positives caused by signal jitter or multiple reflections; the counting signal provides accurate steel ball feeding feedback for the whole machine control system, thereby realizing closed-loop monitoring and missing assembly early warning of the assembly quantity.

[0109] In summary, the application not only significantly improves the accuracy, stability and anti-interference ability of steel ball feeding, but also realizes self-adaptive processing of different specifications of steel balls through modular time sequence control, greatly enhances the flexibility and reliability of the equipment in the multi-specification and high-rhythm production environment, and provides a solid technical guarantee for high-quality automatic assembly of double-row steel ball quick connectors.

[0110] In some embodiments, the bottom plate 520 is provided with two connection seats 521 symmetrically arranged on the side facing the workbench, and the material guide assembly 700 is detachably installed on the connection seat 521.

[0111] Further, the connection seat 521 is a U-shaped structure, and the material guide assembly 700 is embedded in the connection seat 521 and fixed by bolts.

[0112] In some embodiments, the connection seat 521 is provided with a Hall sensor 521b, and the corresponding position of the material guide assembly 700 is provided with a magnet, and the Hall sensor 521b is used to detect whether the material guide assembly 700 is installed in place.

[0113] In the above embodiment, the application sets the connecting seat 521 on the side of the bottom plate 520 facing the workbench, and detachably installs the material guiding assembly 700 thereon, so as to facilitate quick replacement of the adaptive material guiding assembly 700 according to different models of double-row steel balls quick connectors, and improve the equipment change efficiency. Meanwhile, the Hall sensor 521b is integrated on the connecting seat 521, and the magnet is arranged at the corresponding position of the material guiding assembly 700, to form a non-contact in-place detection mechanism. When the material guiding assembly 700 is correctly installed in place, the magnet is aligned with the Hall sensor 521b, an induction signal is triggered, and the control system confirms that the material guiding assembly 700 has been reliably positioned, so that the assembly process can be started. This design effectively avoids the mispositioning, jamming or even equipment failure of the steel balls caused by the non-installation, incorrect installation or loosening of the material guiding assembly 700, improves the operation safety and assembly reliability, and realizes the automatic verification function before assembly, which provides an important guarantee for the full-process automation and error-proof control.

[0114] In some embodiments, the material guiding assembly 700 includes a material guiding shell 710, a first sealing cover 711, a second sealing cover 712, and a material guiding pipe 720.

[0115] In some embodiments, the material guiding shell 710 is a hollow structure, and the first sealing cover 711 and the second sealing cover 712 are respectively sealingly arranged at two ends of the material guiding shell 710; the feeding hole 711a is arranged on the first sealing cover 711, and the discharging hole 712a is arranged on the second sealing cover 712.

[0116] Further, the feeding hole 711a is a funnel-shaped structure, and the inner diameter of the end thereof facing the second channel 592 is equal to the inner diameter of the second channel 592, so as to ensure that the steel balls are smoothly transferred from the second channel 592 to the feeding hole 711a and smoothly enter the material guiding pipe 720, and avoid jamming or deflection caused by sudden change of cross section.

[0117] In some embodiments, the material guiding pipe 720 is arranged in the material guiding shell 710, one end of the material guiding pipe 720 communicates with the feeding hole 711a, and the other end of the material guiding pipe 720 communicates with the discharging hole 712a; the air cavity 713 is formed between the material guiding shell 710 and the material guiding pipe 720, the side wall of the material guiding shell 710 is provided with the pipe plug 714, the connecting seat 521 is provided with the insertion hole 521a matched with the pipe plug 714, and the pipe plug 714 is inserted into the insertion hole 521a; a plurality of air injection ports 721 are arranged on the side wall of the material guiding pipe 720, the air injection ports 721 inject air flow at an acute angle with the discharging direction of the steel balls, specifically, the air injection ports 721 inject air flow obliquely downward, and the air injection ports 721 are used for pushing the steel balls to move downward along the material guiding pipe 720 by high-pressure gas.

[0118] Further, the end of the material guiding pipe 720 extends out of the discharging hole 712a, so as to facilitate the staff to conveniently check whether the discharging end of the material guiding pipe 720 is aligned with the radial through hole of the shell.

[0119] Further, the center line of the material guide pipe 720 is arc-shaped and extends downward as a whole. Specifically, the center line of the material guide pipe 720 is a spatial curve.

[0120] Further, the inner diameter of the material guide pipe 720 is slightly larger than the diameter of the steel ball.

[0121] Further, a sealing ring is arranged between the insertion pipe 714 and the insertion hole 521a to achieve airtight connection and prevent high-pressure gas from leaking at the interface.

[0122] Further, a spiral path is defined along the arc-shaped center line of the material guide pipe 720 on the surface of the pipe wall, and the air outlets 721 are arranged along the spiral path, so that the airflow action points are more uniformly distributed during the movement of the steel ball, effectively avoiding the deflection, stagnation or accumulation of the steel ball in the curved section, and improving the stability and reliability of the conveying.

[0123] In the above embodiment, the application constructs an internal pneumatic boosting structure by arranging the material guide shell 710, the material guide pipe 720 and the air cavity 713 therebetween in the material guide assembly 700, and opening the air outlets 721 at the side wall of the material guide pipe 720 at an acute angle to the discharge direction of the steel ball. The application effectively solves the problem of stagnation of the steel ball caused by friction, surface roughness or small foreign matter during the material guiding process. Specifically, after the high-pressure gas enters the insertion pipe 714 through the insertion hole 521a of the connecting seat 521, it flows into the air cavity 713 between the material guide shell 710 and the material guide pipe 720, and is injected to the surface of the steel ball at an inclined direction through the air outlet 721, forming a thrust component along the axial direction of the material guide pipe 720, continuously pushing the steel ball to move smoothly. Since the direction of the airflow is at an acute angle to the direction of the movement of the steel ball, it not only avoids the rebound or jumping caused by the direct impact, but also provides stable and continuous propulsion, significantly improving the conveying reliability. At the same time, the material guide assembly 700 as a whole adopts a sealed structure, with the first sealing cover 711 and the second sealing cover 712 closing the two ends of the material guide shell 710, to ensure the stability of the pressure in the air cavity 713 and prevent air leakage from causing insufficient thrust. The cooperation of the insertion pipe 714 and the insertion hole 521a of the connecting seat 521 not only realizes the quick connection of the air path, but also facilitates the overall disassembly and maintenance of the material guide assembly 700. This design uses air pressure to push the steel ball without increasing external driving mechanisms, effectively preventing the phenomena of jamming and blocking of the steel ball, ensuring the assembly rhythm and yield rate, and is especially suitable for high-precision and high-speed synchronous assembly of double rows of steel balls.

[0124] In some embodiments, the storage bin 500 is provided with a guide pipe 540 in the axial direction.

[0125] In some embodiments, the assembly device further includes a gas guiding assembly 580, which includes an air inlet pipe 581. The outer diameter of the air inlet pipe 581 is smaller than the inner diameter of the conduit 540. The air inlet pipe 581 is inserted into the conduit 540, and one end of the air inlet pipe 581 extends out of the conduit 540 and is connected to a connector 581a. The connector 581a is connected to a high-pressure gas source through a pipeline. The connector 581a facilitates disconnecting the gas source when changing the storage bin 500. The high-pressure gas source can be a high-pressure gas cylinder with a control valve, or a conventional gas supply device such as an air compressor with a control valve. Its specific type and configuration can be flexibly selected according to the actual working conditions.

[0126] In some embodiments, the assembly device includes a transfer pipe 582, which is fixed to the base plate 520. One end of the air inlet pipe 581, away from the connector 581a, is rotatably connected to the transfer pipe 582 via a rotary connector 583, thereby achieving dynamic airflow communication between the stationary air source and the rotating components. The transfer pipe 582 is connected to air-consuming components such as the socket 521a, the first air outlet 591b, and the first drive mechanism 593 via internal or external pipelines. More precisely, the transfer pipe 582 serves as the airflow distribution hub on the storage silo 500 side, providing unified air supply to all actuators on the storage silo 500 that require high-pressure gas, ensuring that each air-consuming point can still obtain stable and reliable airflow support during the rotation of the storage silo 500.

[0127] In some embodiments, the storage hopper 500 is equipped with a coprocessing module, which includes a control chip, a memory, a wireless communication module, and supporting control circuitry. The wireless communication module of the coprocessing module establishes a connection with the wireless communication module of the main control module inside the chassis 100 via Wi-Fi, Bluetooth, or other short-range wireless communication protocols to achieve bidirectional data exchange. The control chip of the coprocessing module is electrically connected to the execution and sensing components on the storage hopper 500, such as the laser counting mechanism 591a, the Hall sensor 521b, the first drive mechanism 593, and the second drive mechanism 594, to collect status signals in real time and control the coordinated action of each component. This distributed control architecture can reduce the burden on the main control system, improve response speed, and support the storage hopper 500 to maintain local intelligent control capabilities during rotation or replacement, thereby enhancing the reliability and flexibility of the entire machine.

[0128] Furthermore, the coprocessor module can be powered by a built-in or external rechargeable or disposable battery, thus eliminating the need for a wired power connection during the 500-degree rotation of the storage hopper and achieving power supply independence and flexibility. The battery can be replaced periodically or replenished via wireless charging, contact charging, or other methods to ensure continuous and stable operation of the coprocessor module throughout its operating cycle. Naturally, the coprocessor module can also be powered by other mature technologies, which will not be elaborated upon in this application.

[0129] For those skilled in the art, after considering the description of the structure and function of this application, the programming of the specific selection, configuration and control method of the coprocessor module is obvious and requires no creative effort. Therefore, its specific implementation details and principles will not be elaborated here.

[0130] In the above embodiments, this application effectively solves the problem of continuous and stable supply of high-pressure gas to the storage silo 500 during rotation by setting a conduit 540 along the axial direction of the storage silo 500 and configuring an air guiding assembly 580 including an air inlet pipe 581, a rotary joint 583, and an adapter pipe 582. Specifically, the air inlet pipe 581 is a fixed component, with one end connected to an external high-pressure gas source and the other end connected to the adapter pipe 582, which rotates synchronously with the storage silo 500, through the rotary joint 583. The adapter pipe 582 is fixed on the bottom plate 520 of the storage silo 500 and is connected to the insertion hole 521a and the first air outlet 591b, respectively. This structure uses the rotary joint 583 to achieve a dynamic sealed connection between the static gas source and the rotating air path, ensuring that high-pressure gas is delivered to the air chamber 713 and the first air outlet 591b of the guiding assembly 700 without leakage or interruption when the storage silo 500 rotates continuously around the housing axis. This not only ensures stable pneumatic drive of steel balls throughout the entire process of discharge, pushing and guiding, avoiding ball jamming or action failure due to poor air supply, but also significantly improves the reliability and automation level of the equipment under high-speed and continuous operation, providing a reliable dynamic air supply guarantee for the high-precision and high-efficiency assembly of double-row steel ball quick connectors.

[0131] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
