Description

Technical Field

[0001] This invention relates to the field of parts assembly technology, and in particular to a foot assembly device and method. Background Technology

[0002] In the production of cabinet-type household appliances and industrial equipment, the threaded section of the foot needs to be screwed into the mounting hole at the bottom of the cabinet. The top of the foot has an integrally formed protrusion. The tightening device transmits torque by engaging the protrusion, thereby driving the foot to complete the thread screwing operation. Stable tightening is achieved by the cooperation between the protrusion and the tightening structure. This is a foot drive structure widely used in current automated assembly lines.

[0003] In the existing automated foot tightening process, the feet are batch-fed by the feeding mechanism without any directional limiting structure. The feet randomly flip within the material channel and the picking station, and their circumferential angles are completely disordered. The orientation and circumferential position of the top protrusions have no fixed pattern. The tightening mechanism has a slot structure that matches the protrusions. Torque can only be transmitted when the protrusions are precisely aligned with the slots. Before each tightening action, an additional rotation positioning station is required to correct the circumferential angle of the feet. The tightening program can only be started after the protrusions and slots are aligned. This increases the number of steps in the assembly of a single foot, lengthens the cycle time, and reduces the overall output efficiency of the production line. The additional positioning mechanism also increases the equipment manufacturing cost and space occupation.

[0004] Meanwhile, the mounting holes on the bottom of different models and irregularly shaped enclosures are not uniformly vertically opened. Some mounting holes extend in an inclined direction, and the threaded section of the anchor bolt needs to be fed in to match the inclination angle of the mounting hole in order to screw it in properly. The existing conventional tightening mechanism has a fixed anchor bolt posture after taking material and cannot adaptively adjust the inclination angle. If there is an angle between the anchor bolt axis and the extension direction of the mounting hole, it is very easy to cause thread collision, stripping, and incomplete locking of defective products. In severe cases, it can cause damage to the anchor bolt threads and the mounting hole threads of the enclosure, increasing the product scrap rate. If the anchor bolt inclination angle is adjusted to match the mounting hole, it will disrupt the automated continuous production process and make it difficult to adapt to the flexible production needs of mixed-specification enclosures.

[0018] This invention also provides a foot assembly method, which uses the aforementioned foot assembly equipment for foot assembly processing, comprising: Step S1, adjusting the assembly frame and its screwing mechanism and docking mechanism to move synchronously to the feeding end of the foot vibrating plate through an adjusting mechanism; Step S2, driving the locking cylinder to move so that the floating block abuts against the adaptive adjustment groove, thereby fixing the angle of the docking mechanism; Step S3, driving the magnetic component to approach and attract the foot, at which time the foot protrusion pushes at least part of the functional column, and the remaining functional columns are inserted between adjacent foot protrusions; Step S4, moving the docking mechanism above the screw hole to be assembled through the adjusting mechanism, releasing the driving force of the locking cylinder so that the floating block and the adaptive adjustment groove are in clearance fit, thereby allowing the mounting block to adaptively adjust its angle relative to the moving shaft; Step S5, after the foot is inserted into the screw hole, driving the rotating component to rotate, the functional columns that are not pushed drive the foot protrusion to rotate, and at the same time the magnetic component drives the moving shaft to compress the screwing spring until the foot assembly is completed, at which point the screwing spring pushes the magnetic component to automatically reset.

[0019] The technical solution of the present invention has the following advantages over the prior art:

[0020] The foot assembly equipment and method described in this invention rely on the aforementioned foot assembly equipment to complete automated foot assembly operations. First, the adjustment mechanism is used to realize the three-dimensional displacement of the overall module by twisting and docking. It can accurately switch between the material picking station and the assembly station and is compatible with the continuous material feeding mode of the vibrating plate.

[0021] During the material handling stage, the locking cylinder can be driven to press the floating block to lock the angle of the docking mechanism. When gripping the foot, the foot is quickly attracted by the magnetic component. The functional column and the foot protrusion interlock to form a stable torque transmission structure. The magnetic component can quickly and stably attract and grip the foot with disordered posture. By utilizing the pushing and locking relationship of the foot protrusion with different functional columns, a stable and reliable torque transmission structure can be formed without the need for circumferential angle positioning and correction of the foot. This completely solves the problem of traditional equipment being unable to be aligned and tightened due to disordered orientation of the foot protrusion, resulting in slippage and free rotation. After the tightening operation is completed, the component can be automatically reset by the tightening spring, ensuring continuous and stable operation of the assembly process.

[0022] Meanwhile, during the tightening stage, this application utilizes an adaptive adjustment groove with an arc-shaped inner wall and a floating block clearance fit structure within the docking mechanism. This allows the mounting block to achieve multi-angle adaptive fine-tuning relative to the moving axis, automatically compensating for mounting hole tilt deviations and assembly alignment errors. This eliminates the need for manual correction or the addition of independent angle positioning stations, significantly simplifying the assembly process, shortening the work cycle, effectively improving the overall production efficiency of the production line, and reducing equipment manufacturing costs and floor space.

[0023] In summary, the overall equipment structure of this application is compact, with a high degree of automation and assembly fault tolerance. It can adapt to the flexible production needs of mixed production lines for multiple specifications of boxes, significantly reduce product defect rate and scrap cost, and improve the stability and versatility of automated assembly operations.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0039] Example 1: See Figures 1 to 12 As shown, this embodiment provides a foundation mounting device, which includes:

[0040] Adjustment mechanism 200;

[0041] Assembly frame 300 includes a fixed base plate 310 and a movable frame 320. The fixed base plate 310 is connected to the free end of the adjustment mechanism 200 so as to move in three dimensions through the adjustment mechanism 200. The movable frame 320 is slidably connected to the fixed base plate 310 in the vertical direction.

[0042] A screwing mechanism 400 includes a drive assembly 410 and a rotating assembly 420. The drive assembly 410 is mounted on the movable frame 320. The rotating assembly 420 includes a rotating cylinder 422, a locking cylinder 423, and a moving shaft 424. The rotating cylinder 422 is connected to the power output end of the drive assembly 410 to rotate around the rotation center line 1001 via the drive assembly 410. The rotating cylinder 422 has a first moving groove extending along its length inside. The locking cylinder 423 includes a cylinder body 4231, a floating block 4232, and a locking spring 4234. The cylinder body 4231 is disposed through the first moving shaft 424. A movable groove is provided, and the movable groove can move along the first movable groove. The locking spring 4234 is sleeved and connected to the outer wall of the cylinder 4231 and abuts against the end face of the rotating cylinder 422. The floating block 4232 is connected to the end of the cylinder 4231 and is located outside the rotating cylinder 422. The cylinder 4231 is provided with a second movable groove extending along its length. The movable shaft 424 includes a shaft 4241 and a screwing spring 4243. The shaft 4241 is disposed through the second movable groove and can move along the second movable groove. The screwing spring 4243 is sleeved and connected to the outer wall of the shaft 4241 and abuts against the end face of the locking cylinder 423.

[0043] A docking mechanism 500 includes a mounting block 510, a magnetic component 550, and multiple functional columns 540. The mounting block 510 is connected to the floating block 4232 and rotates synchronously with the rotating cylinder 422. The mounting block 510 has an adaptive adjustment groove 511 and multiple connecting through holes inside. The inner wall of the adaptive adjustment groove 511 is configured with an arc-shaped surface structure. The floating block 4232 is disposed in the adaptive adjustment groove 511 and is clearance-fitted with the adaptive adjustment groove 511 so that the mounting block 510 can adaptively adjust its angle relative to the moving axis 424. The magnetic component 550 is connected to the mounting block 510. The bottom of the mounting block 510 is attached to the foot 100, and the top surface of the magnetic component 550 abuts against the moving shaft 424 through the connecting pin 560. Multiple connecting through holes are arranged around the adaptive adjustment groove 511 and extend through the height direction of the mounting block 510. Multiple functional posts 540 are correspondingly connected to the multiple connecting through holes and can move along the corresponding connecting through holes. After the magnetic component 550 attaches to the foot 100, at least some of the functional posts 540 are pushed by the foot protrusion 110, and the remaining functional posts 540 are inserted between adjacent foot protrusions 110 so that the foot 100 can be screwed by rotating the mounting block 510.

[0044] It should be noted that, for ease of description, in this embodiment, the length direction of the foot assembly device is defined as the first direction X, the width direction of the foot assembly device is defined as the second direction Y, and the height direction of the foot assembly device is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular to each other, and the first direction X and the second direction Y are located in the same plane.

[0045] In this embodiment, the adjustment mechanism 200 serves as the displacement driving carrier of the whole machine. Its free end supports the overall structure of the assembly frame 300 and can simultaneously drive the assembly frame 300, the screwing mechanism 400, and the docking mechanism 500 to complete the movement and adjustment in three-dimensional space. It can flexibly switch positions between the material picking station of the vibrating plate and the box assembly station, and can also precisely fine-tune the relative positions of the docking mechanism 500, the foot 100, and the box mounting holes. It adapts to various box arrangements and station spacings, providing a large-scale, high-precision displacement basis for material picking and alignment processes.

[0046] Further, the adjustment mechanism 200 includes a first moving component 210, a second moving component 220, and a third moving component 230. The first moving component 210 includes a first driver 211, a first guide rail 212, and a first carriage 213. The first guide rail 212 extends along a first direction X. The first driver 211 is disposed at one end of the first guide rail 212, and its power output end is connected to the first carriage 213 to drive the first carriage 213 to move horizontally along the first guide rail 212. The second moving component 220 includes a second driver 221, a second guide rail 222, and a second carriage 223. The second guide rail 222 is disposed at one end of the first guide rail 212. A third moving component 230 includes a third driver 231, a third guide rail 232, and a third slide 233. The third guide rail 232 is disposed on the second slide 223 and extends along a third direction Z. The third driver 231 is disposed on one end of the third guide rail 232 and its power output end is connected to the third slide 233 to drive the third slide 233 to move up and down along the third guide rail 232.

[0047] Specifically, the adjustment mechanism 200 achieves high-precision three-dimensional spatial adjustment of the entire device through the hierarchical nesting of the first moving component 210, the second moving component 220, and the third moving component 230. The first moving component 210 relies on the first guide rail 212 extending along the first direction X as a guiding reference. Powered by the first driver 211, it drives the first carriage 213 to precisely translate horizontally along the first guide rail 212, achieving coarse and fine adjustments to the overall position of the device in the first dimension. The second moving component 220 is mounted on the first carriage 213 and can move synchronously with it. Simultaneously, through the driving cooperation of the second guide rail 222 extending along the second direction Y and the second driver 221, it drives the second carriage 223 to move independently horizontally along the second direction Y, thereby achieving displacement adjustment of the device in the second dimension. 210 works together to form a two-dimensional precise alignment function in the horizontal plane; the third moving component 230 is installed on the second slide 223 and can move synchronously with the two-dimensional structure in the horizontal plane. Through the driving action of the third guide rail 232 arranged along the third direction Z and the third driver 231, the third slide 233 is driven to achieve stable lifting and lowering along the third direction Z, completing the precise adjustment of the vertical height of the equipment and the feeding action. Through the three-dimensional displacement adjustment structure with the cooperation of the three moving components and independent controllability, it can flexibly and accurately drive the rear assembly frame 300, the turning mechanism 400 and the docking mechanism 500 to complete multi-directional position switching and fine adjustment in space, accurately adapting to the alignment requirements of the vibrating material tray picking station and the box assembly station, effectively compensating for station deviation and assembly position error, and providing a stable and precise three-dimensional motion foundation for the automated picking, precise alignment and flexible assembly of the foot 100.

[0048] In this embodiment, the assembly frame 300 includes two parts: a fixed base plate 310 and a movable frame 320. The fixed base plate 310 is connected to the free end of the adjustment mechanism 200 and serves as the bearing base of the screwing mechanism 400. It can simultaneously receive the three-dimensional displacement output by the adjustment mechanism 200 and transmit the displacement action synchronously to all the screwing and docking execution components. The movable frame 320 is slidably mounted on the fixed base plate 310 in the vertical direction and can independently complete the vertical lifting action relative to the fixed base plate 310. It provides vertical buffer stroke when the foot 100 grips and the foot 100 extends into the mounting hole. It works with the internal elastic structure to buffer the impact generated by the downward pressure and at the same time provides a stable installation position for various components of the screwing mechanism 400 and constrains the overall installation reference of the drive component 410 and the rotating component 420.

[0049] Specifically, the movable frame 320 includes a top plate 321, a bottom plate 323, and guide posts 322. The guide posts 322 extend vertically and are connected to the fixed base plate 310. The top plate 321 and the bottom plate 323 are respectively connected to the opposite ends of the guide posts 322. The top plate 321 is located above the fixed base plate 310, and the bottom plate 323 is located below the fixed base plate 310. The vertically extending guide post 322 penetrates the interior of the fixed base plate 310, providing precise vertical sliding guidance for the entire movable frame 320. This ensures that the movable frame 320 can only move smoothly up and down in the vertical direction, effectively limiting horizontal offset and swaying, and improving overall motion accuracy and structural stability. The top plate 321 and the bottom plate 323 are fixedly connected at their upper and lower ends, respectively, forming an integrated rigid frame structure with the top plate 321, bottom plate 323, and guide post 322. The top plate 321, located above the fixed base plate 310, can control the screwing mechanism mounted on the movable frame 320. The top limit and load-bearing support of the 400 mechanism are provided. The bottom plate 323 located below the fixed base plate 310 can provide an installation reference and load-bearing limit for the bottom structure of the screwing mechanism 400. The overall structure achieves the vertical adaptive floating stroke of the screwing mechanism 400 without affecting the three-dimensional alignment accuracy of the adjustment mechanism 200. It can effectively adapt to the vertical feed displacement during the material picking and pressing screwing process of the foot 100, buffer the assembly contact impact, and ensure the stable and reliable operation of the structure during the screwing operation.

[0050] Furthermore, the movable frame 320 also includes an extension plate 324 and a material detector 325. The extension plate 324 is connected to the base plate 323, and the material detector 325 is disposed on the extension plate 324 with its detection end facing the fixed base plate 310. The mobile frame 320 provides a stable external mounting carrier for the material detector 325, effectively expanding the installation space of the mobile frame 320. This allows the material detector 325 to be suspended on the side of the equipment's working area, avoiding interference with other moving structures. Simultaneously, the material detector 325 is mounted on the extension plate 324 with its detection end facing the fixed base plate 310. It can move synchronously with the vertical sliding of the mobile frame 320 and the three-dimensional displacement of the entire equipment, accurately detecting in real time whether there is material at the picking station and whether the gripping status of the foot 100 is normal. It can provide real-time feedback on the equipment's picking and alignment status, achieving automatic monitoring and feedback of material presence and success / failure. This provides accurate detection signals for automated start-up and shutdown and continuous cyclic assembly operations, effectively avoiding abnormal conditions such as empty tightening, missed picking, and gripping failure, thus improving the overall stability and intelligent monitoring capabilities of the automated equipment operation.

[0051] In addition, the assembly frame 300 in this embodiment is also provided with a buffer assembly 330. The buffer assembly 330 includes a connecting plate 333, a buffer member 332, and a buffer guide post 331. The connecting plate 333 is connected to the rotating assembly 420. The buffer guide post 331 passes through and is connected to the connecting plate 333 and extends in the vertical direction. The buffer member 332 is sleeved on the buffer guide post 331, with one end connected to the top of the buffer guide post 331 and the other end supported by the connecting plate 333. The top of the buffer guide post 331 can abut against the top plate 321. The connecting plate 333 is connected to the rotating component 420 to achieve synchronous movement of the buffer component 330 and the rotating component 420. The buffer guide post 331, which passes through the connecting plate 333 in the vertical direction, provides vertical guidance and constraint for the overall buffering action, preventing horizontal deviation during the buffering process. The buffer member 332, which is fitted outside the buffer guide post 331, abuts against the top of the buffer guide post 331 and the connecting plate 333 at both ends, and can generate vertical buffering force by its own elasticity. When the foot 100 is pressed down and screwed, the top of the buffer guide post 331 moves downward and fits against the top plate 321. The top plate 321 supports the buffer guide post 331. 1. The upper limit is formed, and the compression buffer 332 absorbs the impact load generated by the downward pressure, which alleviates the rigid collision during the twisting moment and reduces the wear and tear on the threads of the foot 100, the rotating component 420 and the docking mechanism 500. After the twisting is completed, the buffer 332 rebounds and drives the buffer guide post 331 to reset. Under the premise of not affecting the normal transmission of the twisting torque, it continues to provide a gentle clamping force to ensure full engagement of the threads. At the same time, the maximum downward stroke is limited by the abutment cooperation between the buffer guide post 331 and the top plate 321 to prevent excessive downward pressure from causing workpiece crushing damage, thereby improving the overall machine operation stability and the service life of the parts.

[0052] In this embodiment, the screwing mechanism 400 is provided with a drive component 410, which is fixedly installed on the movable frame 320. As the power input source of the entire rotating component 420, it can output rotational torque to drive the rotating cylinder 422 to rotate around its own central axis, thereby synchronously driving the locking cylinder 423, the moving shaft 424 and the docking mechanism 500 to rotate as a whole, providing continuous and reliable rotational power for the tightening operation of the foot 100.

[0053] Specifically, the drive assembly 410 includes a base frame 411, a rotary driver 412, a transmission belt 413, and a rotary drive wheel 414. The base frame 411 is connected to the movable frame 320, the rotary driver 412 is disposed on the base frame 411, the rotary drive wheel 414 is sleeved on the rotating cylinder 422, and the two ends of the transmission belt 413 are respectively sleeved on the power output end of the rotary driver 412 and the rotary drive wheel 414. The drive assembly 410 provides a stable mounting base for the rotary drive 412 through the base frame 411 connected to the mobile frame 320, ensuring that the position of the power component is stable and does not shift during operation. The rotary drive 412, mounted on the base frame 411, outputs rotational power as a rotational power source. The rotary drive wheel 414, sleeved on the outside of the rotary cylinder 422, receives the torque transmitted by the transmission belt 413 and synchronously drives the rotary cylinder 422 to rotate as a whole. The transmission belt 413, with its two ends respectively covering the output end of the rotary drive 412 and the rotary drive wheel 414, realizes flexible power transmission, which can buffer the impact load at the moment of start-up and stop of the drive, reduce the noise and component wear caused by rigid transmission. The entire transmission structure is compact and can stably and continuously transmit the torque output by the rotary drive 412 to the rotary cylinder 422 efficiently, ensuring continuous and slip-free power transmission during the tightening operation, and providing a stable and reliable rotary driving force for the tightening assembly of the foot 100.

[0054] In this embodiment, the rotating cylinder 422 in the rotating assembly 420 is connected to the power output end of the driving assembly 410 and rotates synchronously with the driving assembly 410. A first moving groove is opened in the cylinder along the length direction to provide an axial sliding guide channel for the cylinder body 4231 of the locking cylinder 423, so as to realize the linear sliding of the locking cylinder 423 along the axial direction of the rotating cylinder 422. At the same time, it serves as an intermediate carrier for torque transmission, synchronously transmitting the rotational torque to the locking cylinder 423, the floating block 4232 and the docking mechanism 500.

[0055] The rotating assembly 420 also includes a connecting cylinder 421, which is connected to the base plate 323 and moves synchronously with the movable frame 320. The connecting cylinder 421 is connected to the rotating cylinder 422 through a bearing disposed inside it. The connecting cylinder 421 can form a stable support carrier based on the base plate 323. The connecting cylinder 421 is equipped with bearings, which rotate in conjunction with the rotating cylinder 422. This not only limits the radial movement of the rotating cylinder 422, restricting radial sway and offset during operation, and ensuring that the rotating cylinder 422 always rotates smoothly along the rotation center line 1001, but also reduces the frictional resistance of the rotating cylinder 422 relative to the connecting cylinder 421, reducing power loss and wear of parts. At the same time, the connecting cylinder 421 moves up and down synchronously with the moving frame 320, maintaining coaxial support and constraint on the rotating cylinder 422 throughout the process. This ensures that the rotating cylinder 422 always has a stable rotation reference during vertical floating and three-dimensional alignment movements, effectively improving the smoothness of torque transmission during twisting operations and extending the service life of the equipment.

[0056] The locking cylinder 423 consists of a cylinder body 4231, a floating block 4232, and a locking spring 4234. The cylinder body 4231 is arranged inside the first moving groove and can move along the groove axis. The second moving groove inside the cylinder body 4231 provides a sliding guide for the moving shaft 424. The locking spring 4234 is sleeved on the outer wall of the cylinder body 4231 and abuts against the end face of the rotating cylinder 422. Under normal conditions, it pushes the cylinder body 4231 and the floating block 4232 outward by its own elastic force. During material handling, the cylinder body 4231 can be retracted by external force to compress the locking spring 4234, so that the floating block 4232 is pressed tightly against the adaptive adjustment groove 5. 11. Lock the angle of the mounting block 510 relative to the moving shaft 424 to ensure the stability of the foot 100 during the material picking stage. After the external force is removed during the assembly and alignment stage, the locking spring 4234 rebounds and pushes the cylinder 4231 back to its original position. The floating block 4232 and the adaptive adjustment groove 511 return to the clearance fit state, and the angle lock of the docking mechanism 500 is released to achieve adaptive angle adjustment. The floating block 4232 is fixed at the end of the cylinder 4231 and placed outside the rotating cylinder 422. By switching between the two states of contact and separation with the adaptive adjustment groove 511, the two working modes of angle locking and adaptive adjustment of the docking mechanism 500 are realized respectively.

[0057] Furthermore, the rotating assembly 420 also includes a locking driver 425, which is connected to the top plate 321 and has its power output end connected to the locking cylinder 423 to drive the locking cylinder 423 to move in the first moving slot. The locking actuator 425 is stably supported by the top plate 321. Its power output end is connected to the locking cylinder 423, which can independently output linear driving force to drive the locking cylinder 423 to slide axially along the first moving groove inside the rotating cylinder 422. This switches the engagement and disengagement states of the floating block 4232 and the adaptive adjustment groove 511. During the material picking stage, the locking actuator 425 pushes the locking cylinder 423 forward to press the floating block 4232 against the adaptive adjustment groove 511, locking the adjustment angle of the mounting block 510 to ensure the stability of the gripping posture of the foot 100. During the assembly alignment stage, the locking actuator 425 pulls the locking cylinder 423 backward to release the pressing constraint of the floating block 4232, so that the floating block 4232 and the adaptive adjustment groove 511 restore the clearance fit, releasing the angle adaptive adjustment capability of the mounting block 510. The entire structure can accurately control the switching between the locking angle and the adjustment angle of the docking mechanism 500. It can automatically match the usage requirements of different processes of material picking and assembly without manual intervention, improving the automation control accuracy of the equipment.

[0058] Furthermore, in this embodiment, the first moving groove is provided with an inwardly protruding first limiting boss, and the outer surface of the cylinder 4231 is provided with a first limiting block 4233. The two ends of the locking spring 4234 abut against the end face of the rotating cylinder 422 and the first limiting block 4233, respectively. During the movement of the cylinder 4231, the first limiting block 4233 can abut against the first limiting boss and interfere. The first limiting boss and the first limiting block 4233 on the outer side of the cylinder 4231 cooperate to form an axial limiting structure. The two ends of the locking spring 4234 abut against the end face of the rotating cylinder 422 and the first limiting block 4233 to continuously apply an outward pushing elastic force to the cylinder 4231. When the cylinder 4231 slides outward along the first moving groove to its limit position, the first limiting block 4233 will abut against the first limiting boss to form mechanical interference, thereby restricting the cylinder 4231 from dislodging out of the first moving groove and preventing the cylinder from locking. When 423 separates from the rotating cylinder 422 and fails, and at the same time, during the process of the locking driver 425 pulling the cylinder 4231 inward to compress the locking spring 4234, the cooperation between the first limiting block 4233 and the first limiting boss can limit the maximum outward movement of the cylinder 4231, constrain the stretching range of the locking spring 4234, prevent the locking spring 4234 from excessively deforming and causing fatigue damage, and ensure that the locking cylinder 423 slides stably in the first moving groove throughout the process, maintaining the continuous and reliable operation of the locking structure's elastic pressing and angle locking functions.

[0059] In this embodiment, the floating block 4232 is provided with a transmission connecting arm 4235, and the mounting block 510 is provided with a snap-fit ​​groove. One end of the transmission connecting arm 4235 is fixed to the floating block 4232, and the other end extends in a direction away from the floating block 4232 and can be movably snapped into the snap-fit ​​groove. One end of the transmission connecting arm 4235 is rigidly connected to the floating block 4232, and the other end extends outward and can be movably engaged in the engagement groove inside the mounting block 510. The synchronous transmission of torque between the floating block 4232 and the mounting block 510 is achieved by the engagement of the transmission connecting arm 4235 and the engagement groove, ensuring that the rotational power output by the rotating cylinder 422 can be completely transmitted to the mounting block 510 to drive the foot 100 to rotate. At the same time, the two adopt a movable engagement form. When the floating block 4232 and the adaptive adjustment groove 511 are in clearance engagement and the mounting block 510 is undergoing angular adaptive deflection, the transmission connecting arm 4235 can move slightly inside the engagement groove to avoid the obstruction. This does not restrict the angle adjustment action of the mounting block 510, thus taking into account the need for stable transmission of rotational torque and not interfering with the function of the docking mechanism 500 to autonomously compensate for assembly tilt errors. This achieves the compatibility and coexistence of torque transmission and angle adaptive adjustment functions.

[0060] In this embodiment, the movable shaft 424 includes a shaft body 4241 and a screwing spring 4243. The shaft body 4241 passes through the second movable groove of the locking cylinder 423 and can slide along the axial direction of the groove. The lower end of the shaft body 4241 abuts against the magnetic component 550 through the connecting pin 560, which can transmit the downward clamping force to the foot 100. The screwing spring 4243 is sleeved on the outer wall of the shaft body 4241, and its two ends abut against the end face of the locking cylinder 423 and the magnetic component 550, respectively. During the screwing and pressing of the foot 100, the magnetic component 550 will drive the shaft body 4241 to move upward and compress the screwing spring 4243, continuously outputting a constant clamping force to ensure full engagement of the threads. After assembly, the screwing spring 4243 rebounds and pushes the magnetic component 550 and the shaft body 4241 to automatically reset downward, which facilitates disengagement from the assembled foot 100 and smoothly starts the next assembly cycle.

[0061] Furthermore, the second moving groove is provided with an inwardly protruding second limiting boss, and the outer surface of the shaft 4241 is provided with a second limiting block 4242. The two ends of the screwing spring 4243 respectively abut against the end face of the locking cylinder 423 and the second limiting block 4242. During the movement of the shaft 4241, the second limiting block 4242 can abut against and interfere with the second limiting boss. The second limiting boss and the second limiting block 4242 on the outer wall of the shaft 4241 cooperate to form an axial limiting structure for the shaft 4241. The two ends of the screwing spring 4243 abut against the end face of the locking cylinder 423 and the second limiting block 4242, respectively. Under normal conditions, the screwing spring 4243 pushes the shaft 4241 and the magnetic component 550 downward by its elastic force. When the shaft 4241 is pushed upward by the foot 100 and slides upward along the second moving groove to compress the screwing spring 4243, the second limiting block 4242 moves upward and can form abutment interference with the second limiting boss, thereby limiting the shaft 4241. The maximum upward stroke of 41 prevents the screwing spring 4243 from being over-compressed and causing permanent deformation failure. At the same time, it can prevent the shaft 4241 from falling out of the second moving groove, ensuring that the shaft 4241 is always confined to the locking cylinder 423 and slides stably. During the screwing operation, it continuously outputs a constant elastic clamping force. After assembly, the screwing spring 4243 can stably rebound to drive the shaft 4241 to reset. Throughout the process, it ensures the axial sliding and elastic clamping reset functions of the moving shaft 424 are stable and reliable, and extends the service life of the screwing spring 4243 and related sliding parts.

[0062] In this embodiment, the mounting block 510 in the docking mechanism 500 is connected to the floating block 4232 and can rotate synchronously with the rotating cylinder 422. It has an adaptive adjustment groove 511 with an arc-shaped inner wall and multiple connecting through holes arranged around it. The adaptive adjustment groove 511 works with the floating block 4232 to realize the angle adaptive adjustment function. The connecting through holes provide an independent vertical sliding limit channel for each functional column 540. The whole structure bears the rotation torque and transmits it to the functional column 540 to drive the foot 100 to complete the turning action. The adaptive adjustment groove 511 with an arc-shaped inner wall can allow the floating block 4232 to shift slightly after the floating block 4232 is unlocked, so that the mounting block 510 can deflect at multiple angles relative to the moving axis 424, automatically compensating for the coaxiality assembly error caused by the inclined mounting hole of the box.

[0063] The magnetic component 550 is installed at the bottom of the mounting block 510. It quickly attracts and fixes the foot 100 by magnetic force, so as to achieve stable gripping of the foot 100 with disordered loading posture. The top surface of the magnetic component 550 abuts against the moving shaft 424 through the connecting nail 560, and receives the elastic downward pressure transmitted by the moving shaft 424, continuously applying a clamping force to the foot 100 to prevent the foot 100 from floating up and getting out of the mating position during the tightening process.

[0064] Multiple functional posts 540 are respectively inserted into the corresponding connecting through holes and can slide freely vertically along the corresponding connecting through holes. When the magnetic component 550 attracts the foot 100, some functional posts 540 are pushed upward by the protrusion 110 on the top of the foot 100, while the remaining functional posts 540 are inserted into the gap between the adjacent foot protrusions 110. When the mounting block 510 rotates, the functional posts 540 that are not pushed against the side wall of the protrusion 110 transmit rotational torque. The foot 100 can be stably driven into the screw hole without prior circumferential angle correction, effectively solving the transmission slippage problem caused by the random orientation of the foot protrusions 110. At the same time, each functional post 540 can slide vertically independently, which can adapt to different protrusion heights and different specifications of foot 100, improving the equipment's universal adaptability.

[0065] Furthermore, the docking mechanism 500 also includes a top fixing ring 530 and a bottom fixing ring 520 respectively disposed on opposite sides of the mounting block 510 in the thickness direction. The functional column 540 passes through the mounting hole of the top fixing ring 530 into the connecting through hole. The floating block 4232 passes through the top fixing ring 530 and is gap-connected to the mounting block 510. The bottom fixing ring 520 is disposed around the magnetic component 550. The top fixing ring 530 and the bottom fixing ring 520 serve to limit and position the components in layers. The functional column 540 passes through the mounting hole in the top fixing ring 530 and enters the connecting through hole inside the mounting block 510. The top fixing ring 530 constrains the upper position of the functional column 540, preventing it from coming off upwards. The floating block 4232 passes through the top fixing ring 530 and then forms a clearance fit with the mounting block 510. The top fixing ring 530 provides radial protection and guide limit for the floating block 4232, preventing it from shifting or getting stuck. The bottom fixing ring is arranged around the magnetic component 550. 520 can laterally surround and limit the magnetic component 550, stabilizing the assembly position of the magnetic component 550 at the bottom of the mounting block 510, preventing the magnetic component 550 from shifting or falling off due to twisting vibration or downward impact. The whole is constrained and positioned layer by layer by the upper fixing ring 530 and the lower fixing ring 520, respectively, to achieve layered constraint and positioning of the functional column 540, floating block 4232 and magnetic component 550, improving the assembly compactness and operational stability of each component of the docking mechanism 500, while not interfering with the vertical sliding of the functional column 540, the adaptive angle adjustment of the mounting block 510 and the normal operation of the magnetic component 550 adsorbing and gripping the foot 100.

[0066] Specifically, the functional column 540 includes a body 542 and a limiting part 541. The limiting part 541 protrudes from the outer surface of the body 542. The body 542 passes through the mounting hole. The limiting part 541 can be supported by the top fixing ring 530. The bottom fixing ring 520 is provided with a plurality of guide grooves 521. The bodies 542 of the plurality of functional columns 540 can move along the guide grooves 521. The main body 542 is inserted into the mounting hole of the top fixing ring 530 to achieve vertical sliding assembly. The protruding limiting part 541 can abut against and support the upper end face of the top fixing ring 530, thereby preventing the functional column 540 from falling downward and avoiding it from falling out of the mounting block 510. The bottom fixing ring 520 has multiple guide grooves 521, each corresponding to the main body 542 of the functional column 540, so that the main body 542 of the functional column 540 can slide smoothly vertically along the guide grooves 521. The guide grooves 521 can guide the functional column 540 downward. The end is radially limited to prevent the functional column 540 from tilting or getting stuck during sliding. The upper and lower parts are respectively supported by the top fixing ring 530 and the bottom fixing ring 520 guide groove 521 to constrain the body 542. The double limiting and guiding structure ensures that all functional columns 540 always remain vertical and slide smoothly. It can float independently upward when the foot protrusion 110 pushes, and can also stably lock into the gap of the foot protrusion 110 to transmit the turning torque. It does not interfere with the adaptive angle adjustment action of the docking mechanism 500 throughout the process, improving the stability of gripping and turning operations.

[0067] In addition, the foot assembly equipment described in this embodiment also includes a navigation mechanism 600 and a control mechanism. The navigation mechanism 600 includes a navigation camera 610, a light source 620, and a quick-release frame 630. The quick-release frame 630 is connected to the movable frame 320. The navigation camera 610 and the light source 620 are respectively connected to the quick-release frame 630, and the light source 620 is located at the detection end of the navigation camera 610. The adjustment mechanism 200, the navigation mechanism 600, and the screwing mechanism 400 are respectively connected to the control mechanism. The navigation mechanism 600 and the control mechanism work together to achieve precise automated control of the entire machine. The quick-release bracket 630, connected to the mobile frame 320 within the navigation mechanism 600, provides a shared mounting platform for the navigation camera 610 and the light source 620. The quick-release bracket 630 is easy to install and remove, facilitating later maintenance and replacement of the navigation camera 610 and the light source 620. Both the navigation camera 610 and the light source 620 are fixed on the quick-release bracket 630, with the light source 620 positioned on the side of the shooting and detection end of the navigation camera 610. During operation, the light source 620 can provide supplemental lighting to the foot 100 and the mounting hole area of ​​the housing, eliminating shadows and improving image clarity to ensure accurate image acquisition by the navigation camera 610. The system integrates material and hole position coordinate information. The control mechanism establishes signal connections with the adjustment mechanism 200, navigation mechanism 600, and screwing mechanism 400 respectively. It can receive image coordinate data transmitted back by the navigation camera 610 and generate displacement commands to drive the adjustment mechanism 200 to complete three-dimensional precise alignment. At the same time, it can control the start and stop of the locking driver 425 and the rotary driver 412 according to the process sequence, switch the locking angle and release state of the locking cylinder 423, and drive the rotary component 420 to complete the screwing action of the foot 100. The entire structure relies on visual navigation to achieve automatic positioning and automatic process flow, without the need for manual alignment assistance, which greatly improves the automation level of the equipment and the assembly alignment accuracy.

[0068] Example 2: This example provides a method for assembling foundation feet, which uses the foundation foot assembly equipment described in Example 1 to perform foundation foot assembly processing, and includes:

[0069] Step S1: Adjust the assembly frame 300 and its screwing mechanism 400 and docking mechanism 500 synchronously to the feeding end of the vibrating material tray at the foot 100 by adjusting the assembly frame 300 and its screwing mechanism 400 and docking mechanism 500. In this embodiment, the adjustment mechanism 200 drives the assembly frame 300 and the screwing mechanism 400 and docking mechanism 500 mounted on it to perform three-dimensional synchronous displacement, so that the docking mechanism 500 is accurately moved to the feeding end position of the vibrating material tray at the foot 100, realizing the precise alignment between the equipment execution end and the feeding station, providing an accurate station position basis for subsequent stable material picking operations, adapting to the continuous automatic feeding operation mode of the vibrating material tray, ensuring that the material picking position is uniform and stable each time, and avoiding material picking failure due to alignment deviation.

[0070] Step S2: Drive the locking cylinder 423 to move so that the floating block 4232 abuts against the adaptive adjustment groove 511, thereby fixing the angle of the docking mechanism 500. By driving the locking cylinder 423 to move, the floating block 4232 and the adaptive adjustment groove 511 of the mounting block 510 abut against each other. The mechanical clamping fit restricts the rotation and deflection freedom of the mounting block 510 relative to the moving axis 424, realizing the rigid locking of the overall angle of the docking mechanism 500. This keeps the posture of the docking mechanism 500 fixed and consistent during the material picking process, effectively preventing the foot 100 from shifting, tilting, or falling off due to the swaying of the mechanism angle when gripping the foot 100. This ensures that the subsequent gripping posture of the foot 100 is stable and reliable, establishing a structural prerequisite for the stable material picking of disordered foot 100.

[0071] Step S3: Drive the magnetic component 550 to approach and attract the connecting foot 100. At this time, the foot protrusion 110 pushes at least some of the functional posts 540, and the remaining functional posts 540 are inserted between adjacent foot protrusions 110. Specifically, by moving the docking mechanism 500 downward, the magnetic component 550 approaches and stably attracts the foot 100, realizing the foot 100's rapid gripping without damage. At the same time, by utilizing the adaptive cooperation relationship between the top protrusion 110 of the foot 100 and each functional post 540, some functional posts 540 are pushed upward by the foot protrusion 110, and the remaining functional posts 540 naturally fit into the gap position of adjacent foot protrusions 110. A reliable torque positioning structure can be formed without circumferential angle correction of the foot 100, which completely adapts to the working conditions of random feeding angle and disordered posture of the foot 100, fundamentally avoiding the problem of torque transmission failure and slippage caused by incorrect orientation of the protrusion 110 in traditional processes.

[0072] Step S4: The docking mechanism 500 is moved above the screw hole to be assembled by the adjusting mechanism 200, and the driving force of the locking cylinder 423 is released so that the floating block 4232 and the adaptive adjustment groove 511 are in clearance fit. This allows the mounting block 510 to be angularly adaptively adjusted relative to the moving shaft 424. Specifically, in this process, the docking mechanism 500, after gripping the foot 100, is moved as a whole to directly above the screw hole to be assembled in the housing by the adjusting mechanism 200, completing the precise switching and alignment of the assembly station. At the same time, the driving constraint of the locking cylinder 423 is released, so that the floating block 4232 and the adaptive adjustment groove 511 switch from a pressing contact state to a clearance fit state. The angle locking restriction of the mounting block 510 is released, so that the mounting block 510 can achieve multi-angle adaptive fine adjustment relative to the moving shaft 424. It can automatically compensate for screw hole tilt, workpiece placement deviation and alignment coaxiality error, ensuring that the posture of the foot 100 can adaptively match the extension angle of the screw hole, avoiding thread collision and scratches caused by hard alignment.

[0073] Step S5: After inserting the foot 100 into the screw hole, drive the rotating assembly 420 to rotate. Relying on the unpush functional column 540 to press against the side wall of the foot protrusion 110, the rotational torque is stably transmitted, driving the foot 100 to continue to screw into the screw hole to complete the locking assembly. During the screwing process, the equipment continuously presses down, causing the magnetic component 550 to drive the moving shaft 424 to slide upward and compress the screwing spring 4243. The elastic energy storage effect of the screwing spring 4243 provides a continuous and constant assembly clamping force, ensuring that the threads are fully engaged and locked in place, effectively preventing problems such as stripping, loose locking, and incomplete assembly. After the foot 100 is assembled and the screwing resistance disappears, the compressed screwing spring 4243 elastically releases and pushes the magnetic component 550 and the moving shaft 424 to automatically reset, realizing the automatic unloading and reset of the mechanism, ensuring that the overall assembly process can run continuously.

[0074] In summary, the foot assembly equipment and method described in this invention completes the automated foot 100 assembly operation by relying on the aforementioned foot assembly equipment. First, the adjustment mechanism 200 is used to realize the three-dimensional displacement of the overall module by twisting and docking. It can accurately switch between the material picking station and the assembly station and is compatible with the continuous material feeding mode of the vibrating plate.

[0075] During the material handling stage, the locking cylinder 423 can be driven to press the floating block 4232 to lock the docking mechanism at an angle of 500. When gripping the foot 100, the foot 100 is quickly attracted by the magnetic component 550. The functional column 540 and the foot protrusion 110 are mutually engaged to form a stable torque transmission structure. The magnetic component 550 can quickly and stably attract and grip the foot 100 with disordered posture. By utilizing the pushing and locking relationship of the foot protrusion 110 with different functional columns 540, a stable and reliable torque transmission structure can be formed without circumferential angle positioning and correction of the foot 100. This completely solves the problem of traditional equipment being unable to be aligned and tightened due to disordered orientation of the foot protrusion 110, resulting in slippage and free rotation. After the screwing operation is completed, the component can be automatically reset by the screwing spring 4243, ensuring continuous and stable operation of the assembly process.

[0076] Meanwhile, during the tightening stage, the present application utilizes the adaptive adjustment groove 511 with an arc-shaped inner wall inside the docking mechanism 500 and the clearance fit structure with the floating block 4232 to enable the mounting block 510 to achieve multi-angle adaptive fine adjustment relative to the moving shaft 424. This can automatically compensate for the tilt deviation of the mounting hole and the assembly alignment error, eliminating the need for manual correction or the addition of an independent angle positioning station. This significantly simplifies the assembly process, shortens the work cycle, effectively improves the overall production efficiency of the production line, and reduces equipment manufacturing costs and floor space.

[0077] In summary, the overall equipment structure of this application is compact, with a high degree of automation and assembly fault tolerance. It can adapt to the flexible production needs of mixed production lines for multiple specifications of boxes, significantly reduce product defect rate and scrap cost, and improve the stability and versatility of automated assembly operations.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
