Description

Technical Field

[0001] This invention relates to the field of mannequin manufacturing technology, and more specifically to an automatic assembly device for mannequin lower limb connectors. Background Technology

[0002] Human mannequins are display models made to human proportions, widely used in clothing design, clothing education, garment cutting and production, industrial garment inspection, and commercial displays. To facilitate assembly, transportation, and flexible adjustment of display poses, mannequins are typically assembled from modular components such as the head, hands, legs, and main body, with connecting parts used for secure fastening. The assembly of the mannequin's lower limbs with these connecting parts is a crucial step in the production process. These connecting parts must be secured to the assembly plate at the top of the lower limbs using screws to ensure a stable and reliable connection between the lower limbs and the mannequin's main body. Currently, the assembly of mannequin lower limbs and connecting parts is generally done manually. The specific operation process is as follows: the operator first places the connecting part into the groove on the surface of the mannequin lower limb assembly plate, and then uses an electric screwdriver or screwdriver to manually lock the screws one by one into the screw holes on the connecting part and the assembly plate. After assembling each mannequin lower limb, the operator needs to manually remove and place the connecting part, manually locate the screw holes, and complete the screwing operation one by one. The manual assembly method has the following defects in actual production: (1) Each screw requires the operator to manually pick up the material, align the hole, press to start and wait for the locking to be completed. The operation time for a single screw is long. When facing a large batch of production orders, there are problems of reduced production efficiency and high labor costs. (2) The fixation of the lower limbs of the model mainly relies on manual placement. There is a lack of dedicated positioning devices to ensure that the lower limbs of multiple models maintain a consistent spacing and posture during the assembly process. At the same time, the loading and unloading of the lower limbs of the model requires manual handling of each piece. There is a lack of automated transfer devices, which results in a large amount of time being spent on loading and unloading. Furthermore, the manual handling process is prone to causing damage to the workpieces. Based on this, the present invention designs an automatic assembly device for connecting parts for lower limbs of models to solve the above problems. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic assembly device for connecting parts for lower limbs of mannequins.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An automatic assembly device for mannequin lower limb connectors includes a mannequin transfer cart, a frame, a Y-axis linear module and an X-axis linear module, wherein the X-axis linear module is fixedly installed above the frame and the Y-axis linear module is fixedly installed at the output end of the X-axis linear module.

The drive motor is fixedly connected to the conveyor frame fixedly installed above the frame. Two sets of rollers are rotatably connected to the surface of the conveyor frame. The belt is slidably connected between the two sets of rollers. One end of one set of rollers is fixedly connected to the output end of the drive motor, and one end of the other set of rollers is fixedly connected to the second transmission gear. Furthermore, the second limiting assembly includes a rotating disk, a second rotating shaft, a connecting rod, a first transmission gear meshing with a second transmission gear, and a second limiting plate for limiting the other end of the mannequin transfer cart. The first transmission gear and the rotating disk are respectively fixedly installed at the upper and lower ends of the second rotating shaft. The second rotating shaft is rotatably connected to the surface of the frame. One end of the connecting rod is hinged to the eccentric position of the rotating disk, and the other end of the connecting rod is hinged to the second limiting plate. The second limiting plate is slidably connected in the guide hole opened in the side wall of the loading and unloading channel. Furthermore, the material handling mechanism includes a first fixed frame, a first lifting block, a first telescopic cylinder, a first elastic element, a fixed block, and a pneumatic clamping component for gripping the connecting component. The output end of the Y-axis linear module is fixedly mounted on a base. The first fixed frame is fixedly mounted on the surface of the base. The first telescopic cylinder and the fixed block are both fixedly connected to the first fixed frame. The first lifting block is fixedly mounted on the output end below the first telescopic cylinder. The fixed block passes through the bottom of the first elastic element. The pneumatic clamping component is fixedly mounted on the bottom end of the first elastic element. The first lifting block is slidably connected to the surface of the first fixed frame. Furthermore, the screw-driving mechanism includes a second fixed frame, a second telescopic cylinder, a second lifting block, a third lifting block, a servo tightening assembly, a screw feeding head, a second elastic element, and a screw feeding tube for conveying screws.

The screw feeding head is fixedly connected to the screw feeding tube at its upper angle, and the screw feeding tube is connected to the screw conveying system. The servo tightening assembly is fixedly installed above the second lifting block, and the output end below the servo tightening assembly is inserted into the upper part of the screw feeding head. The upper part of the second elastic element is fixedly connected to the lower part of the second lifting block, and the second elastic element passes through the third lifting block. Furthermore, the upper surface of the belt is provided with several storage slots for placing connectors, and two or four positioning pins for passing through the screw holes on the surface of the connectors are fixedly installed in the storage slots.

[0005] Compared with the prior art, the beneficial effects of this invention are as follows: 1. When this invention is working, the operator only needs to align the slot with the leg support rod and insert the leg support rod into the slot, which facilitates the support and fixation of the model's lower limbs, and facilitates subsequent centralized screw driving. The operator can directly push the model transfer cart with multiple model lower limbs into the loading and unloading channel. After the screw driving is completed, the belt conveyor first controls several connecting parts to move a preset distance, which can simultaneously control the second limiting component to move a preset distance away from the model transfer cart, which is used to release the limitation on the end of the model transfer cart away from the first limiting component. When the operator moves the model transfer cart out of the loading and unloading channel to complete the unloading, the belt conveyor again controls several connecting parts to move a preset distance, which can simultaneously control the second limiting component to move a preset distance towards the model transfer cart, which is used to limit the end of the model transfer cart away from the first limiting component. This realizes the function of automatically limiting and releasing the limitation of the model transfer cart using the power of the belt conveyor, and has the characteristic of facilitating unloading. 2. This invention utilizes a Y-axis linear module, an X-axis linear module, and a material handling mechanism that work together. After the belt conveyor controls several connectors to be horizontally aligned with the lower limbs of several mannequins, the X-axis linear module controls the material handling mechanism to move to the position of the connector, and the Y-axis linear module controls the material handling mechanism to move directly above a connector. The first telescopic cylinder controls the first lifting block, the first elastic element, the fixing block, and the pneumatic clamping element to descend a preset distance together. The pneumatic clamping element grabs the spherical protrusion at the center of the connector. After the first telescopic cylinder controls the pneumatic clamping element to rise and reset, the X-axis linear module and the Y-axis linear module work together to control the pneumatic clamping element to move directly above the groove on the surface of the assembly plate. The X-axis linear module and the Y-axis linear module work together to control the connector to be placed into the groove. This process is repeated until several connectors are placed into the groove in sequence, thus automatically feeding the connectors. 3. This invention achieves automatic conveying of connectors by setting up a belt conveyor and driving a motor to control the belt movement through rollers. The setting of two or four positioning pins plays a role in pre-positioning the connectors. After the connectors are placed in the grooves on the surface of the assembly plate, the screw holes of the connectors can be aligned with the screw holes in the grooves, thereby improving the installation accuracy of the connectors and the assembly plate.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0010] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 An automatic assembly device for connecting lower limbs of a mannequin includes a mannequin transfer cart 1, a frame 3, a Y-axis linear module 4 and an X-axis linear module 8. The X-axis linear module 8 is fixedly installed above the frame 3, and the Y-axis linear module 4 is fixedly installed at the output end of the X-axis linear module 8. Both the Y-axis linear module 4 and the X-axis linear module 8 are linear modules. The model transfer cart 1 is slidably connected to the loading and unloading channel 31 opened below the frame 3; The model transfer vehicle 1 is fixedly installed with a leg support rod 12. The lower leg of the model 2 has an integrally formed slot 22, into which the leg support rod 12 can be inserted. The top of the model 2 has an integrally formed assembly plate 21, into which a connector 23 can be embedded in the groove on the upper surface of the assembly plate 21. The loading and unloading channel 31 is equipped with a first limiting component 32 and a second limiting component 33 at both ends to limit the two ends of the model transfer cart 1. A belt conveyor 7 for conveying the connector 23 is installed above the frame 3; The output end of the Y-direction linear module 4 is equipped with a material handling mechanism 5 for placing the connector 23 in the groove on the upper surface of the assembly plate 21 and a screw-driving mechanism 6 for driving screws on the surface of the connector 23. The material handling mechanism 5 includes a first fixed frame 51, a first lifting block 52, a first telescopic cylinder 53, a first elastic element 55, a fixed block 56, and a pneumatic clamping member 54 for gripping the connecting member 23. The output end of the Y-axis linear module 4 is fixedly mounted on a base 41. The first fixed frame 51 is fixedly mounted on the surface of the base 41. The first telescopic cylinder 53 and the fixed block 56 are both fixedly connected to the first fixed frame 51. The first lifting block 52 is fixedly mounted on the output end below the first telescopic cylinder 53. The first elastic element 55 passes through the fixed block 56. The first elastic element 55 includes a movable rod and a spring. The top end of the movable rod is fixedly connected to the first lifting block 52. The spring is sleeved on the surface of the movable rod. The upper and lower ends of the spring abut against the first lifting block 52 and the fixed block 56, respectively. The pneumatic clamping member 54 is fixedly mounted on the bottom end of the movable rod. The first lifting block 52 is slidably connected to the surface of the first fixed frame 51. The pneumatic clamping member 54 is a relatively mature parallel gripper in the prior art, and its specific structure will not be described in detail. The screw-driving mechanism 6 includes a second fixed frame 61, a second telescopic cylinder 64, a second lifting block 62, a third lifting block 63, a servo tightening assembly 65, a screw feeding head 66, a second elastic element 67, and a screw feeding tube 68 for conveying screws. The second fixed frame 61 is fixedly mounted on the surface of the base 41, the second telescopic cylinder 64 is fixedly mounted on the surface of the second fixed frame 61, the second lifting block 62 is fixedly mounted on the output end below the second telescopic cylinder 64, and both the second lifting block 62 and the third lifting block 63 are slidably connected to the second fixed frame 61. The screw feeding head 66 is fixedly connected to the screw feeding tube 68 at its upper angle, and the screw feeding tube 68 is connected to the screw conveying system. The servo tightening assembly 65 is fixedly mounted above the second lifting block 62. The output end below the tightening assembly 65 is inserted into the top of the screw feeder 66. The top of the second elastic element 67 is fixedly connected to the bottom of the second lifting block 62. The second elastic element 67 passes through the third lifting block 63. The second elastic element 67 includes a movable rod and a spring. The top end of the movable rod is fixedly connected to the second lifting block 62. The spring is sleeved on the surface of the movable rod. The upper and lower ends of the spring abut against the second lifting block 62 and the third lifting block 63, respectively. The bottom end of the movable rod passes through the third lifting block 63. The screw conveying system is used to convey screws from the feeding end to the screw feeder 66 in an orderly and continuous manner. It is fixedly connected to the upper oblique interface of the screw feeder 66 through the screw feeding tube 68. The screw conveying system mainly includes: a screw feeder such as a vibratory feeder or a stepped feeder, a screw feeding tube 68 (i.e., a screw conveying hose or rigid tube), and a conveying drive assembly blowing device or vacuum generator. The feeder is installed on one side of the frame 3 or placed independently next to the equipment. The feeder is equipped with a hopper and a distributing mechanism for sorting and arranging screws. After being sorted by the feeder, the screws are output one by one to the inlet end of the screw feeding tube 68, with the heads facing upwards or downwards, depending on the specific process requirements. The feeder can be a vibratory feeder, which uses the directional vibration of the vibratory plate to arrange the screws along a spiral track for output; or a stepped feeder can be used, which uses push plates to push the screws step by step to the outlet. A compressed air pipeline is connected to the outlet end of the feeder or the inlet end of the screw feeding tube 68, and compressed air is used to blow the screws along the screw feeding tube 68 to the screw unloading head 66. The servo tightening assembly 65 mainly includes: a servo motor, a planetary or harmonic reducer, a coupling, a torque sensor, and screwdriver bits. The servo motor has a built-in encoder that can provide real-time feedback on the motor's speed, angle, and position. The reducer is connected to the output end of the servo motor to reduce the speed and increase the output torque. The coupling connects the reducer's output shaft to the screwdriver bit, transmitting torque and compensating for coaxiality deviations between them. The screwdriver bit is a replaceable screwdriver tip, the shape of which matches the Phillips head or slotted head of the screw. The screwdriver bit is connected to the output end of the servo motor via the coupling and rotates under the drive of the servo motor, screwing the screw into the screw hole. The torque sensor is installed at the output end of the servo motor or the screwdriver bit connection point to detect the tightening torque in real time and feed the signal back to the controller.

[0011] In this embodiment, when an automatic assembly device for mannequin lower limb connectors is working normally, the leg support rods 12 allow the operator to simply place the mannequin lower limb 2 into the mannequin transfer cart 1, align the slot 22 with the leg support rod 12, and insert the leg support rod 12 into the slot 22. This facilitates support and fixation of the mannequin lower limb 2. The horizontally and evenly arranged leg support rods 12 ensure consistent spacing between the mannequin lower limbs 2, thus positioning them and facilitating subsequent screwing. The first limiting component 32 allows the operator to directly push the mannequin transfer cart 1, containing multiple mannequin lower limbs 2, into the loading / unloading channel 31 for easy loading. It also prevents the mannequin transfer cart 1 from moving in the opposite direction, limiting one end of the mannequin transfer cart 1. The belt conveyor 7 connects with the second limiting component 33. With the coordinated setup, after the screwing is completed, the belt conveyor 7 first controls several connecting parts 23 to move a preset distance. At the same time, the belt conveyor 7 can synchronously control the second limiting component 33 to move a preset distance away from the mannequin transfer cart 1, which is used to release the limitation on the end of the mannequin transfer cart 1 away from the first limiting component 32. When the worker moves the mannequin transfer cart 1 out of the loading and unloading channel 31 to complete the unloading, the belt conveyor 7 again controls several connecting parts 23 to move a preset distance. At this time, several connecting parts 23 can be horizontally aligned with several mannequin lower limbs 2. The belt conveyor 7 can synchronously control the second limiting component 33 to move a preset distance closer to the mannequin transfer cart 1, which is used to limit the end of the mannequin transfer cart 1 away from the first limiting component 32. This realizes the function of automatically limiting and releasing the limitation of the mannequin transfer cart 1 using the power of the belt conveyor 7, and has the feature of facilitating unloading. Through the coordinated arrangement of the Y-axis linear module 4, the X-axis linear module 8, and the material handling mechanism 5, the belt conveyor 7 controls several connecting parts 23 to be horizontally aligned with several mannequin lower limbs 2. Then, the X-axis linear module 8 controls the material handling mechanism 5 to move to the position of the connecting part 23, and the Y-axis linear module 4 controls the material handling mechanism 5 to move directly above a certain connecting part 23. The first telescopic cylinder 53 controls the first lifting block 52, the first elastic element 55, and the pneumatic clamping element 54 to descend a preset distance together, utilizing pneumatic... The clamping member 54 grabs the spherical protrusion at the center of the connector 23. After the first telescopic cylinder 53 controls the pneumatic clamping member 54 to rise and reset, the X-axis linear module 8 and the Y-axis linear module 4 cooperate to control the pneumatic clamping member 54 to move directly above the groove on the surface of the assembly plate 21. The X-axis linear module 8 and the Y-axis linear module 4 cooperate to control the connector 23 to be placed into the groove. This process is repeated until several connectors 23 are placed into the groove in sequence, thus automatically feeding the connectors 23. With the Y-axis linear module 4, X-axis linear module 8, and screw-driving mechanism 6, the X-axis linear module 8 and Y-axis linear module 4 work together to control the screw cutting head 66 to move directly above the screw hole on the surface of the connector 23. The second telescopic cylinder 64 controls the second lifting block 62, servo tightening component 65, second elastic element 67, third lifting block 63, and screw feeding tube 68 to move downwards by a preset distance, so that the bottom of the screw cutting head 66 contacts the surface of the connector 23. The screw conveying system conveys the screw into the screw cutting head 66, ensuring that the screw accurately enters the screw hole. When the second telescopic cylinder 64 controls the second lifting block 62, servo tightening component 65, and second elastic element 67 to move downwards, the blocked third lifting block 63 remains stationary, allowing the bit to enter the screw cutting head 66 and contact the cross groove or slotted groove on the top of the screw. The servo motor starts and drives the bit to rotate through the reducer and coupling. The bit drives the screw to rotate and screw it into the screw hole on the surface of the connector 23. During the tightening process, the encoder built into the servo motor provides real-time feedback on the rotation angle and speed. Precise control of the tightening torque is achieved through the servo motor's current loop control or feedback signals from the torque sensor. When the tightening torque reaches the preset value, the servo motor stops rotating, completing the automatic locking of a single screw and improving work efficiency.

[0012] Example 2: In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of the present invention, the bottom of the mannequin transfer cart 1 is fixedly equipped with casters 13, the two sides of the mannequin transfer cart 1 are fixedly equipped with limiting side plates 11 that are slidably connected to the bottom of the loading and unloading channel 31, and both ends of the mannequin transfer cart 1 are fixedly equipped with handles 14.

[0013] In this embodiment, with the mannequin transfer cart 1, during loading, the worker pushes the mannequin transfer cart 1 into the loading / unloading channel 31 by holding the handle 14. The bottom of the loading / unloading channel 31 is longitudinally limited by the limiting side plate 11. For unloading the first and last mannequin transfer cart 1, the worker can directly pull or push the mannequin transfer cart 1 out of the loading / unloading channel 31 by holding the handle 14. For unloading the mannequin transfer cart 1 in the middle stage, another mannequin transfer cart 1 that needs to be screwed can be directly pushed into the loading / unloading channel 31. This method can simultaneously complete the loading and unloading of the mannequin transfer cart 1, improving work efficiency.

[0014] Example 3: In some embodiments, such as Figures 1-9 As shown, in a preferred embodiment of the present invention, the belt conveyor 7 includes a drive motor 72, rollers 73, a belt 71 for conveying the connector 23, and a second transmission gear 74 for transmission connection with the second limiting component 33. The drive motor 72 is fixedly connected to the conveyor frame fixedly installed above the frame 3. Two sets of rollers 73 are rotatably connected to the surface of the conveyor frame. The belt 71 is slidably connected between the two sets of rollers 73. One end of one set of rollers 73 is fixedly connected to the output end of the drive motor 72, and one end of the other set of rollers 73 is fixedly connected to the second transmission gear 74. The upper surface of the belt 71 is provided with several storage slots 711 for placing the connector 23. Two or four positioning pins 712 for passing through the screw holes on the surface of the connector 23 are fixedly installed in the storage slots 711.

[0015] In this embodiment, the belt conveyor 7 is used to drive the motor 72 to control the belt 71 to move via the roller 73, thereby realizing the automatic conveying of the connector 23. The setting of two or four positioning pins 712 plays the role of pre-positioning the connector 23. After the connector 23 is placed in the groove on the surface of the assembly plate 21, the screw hole of the connector 23 can be aligned with the screw hole in the groove, thereby improving the installation accuracy of the connector 23 and the assembly plate 21.

[0016] Example 4: In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of the present invention, the first limiting component 32 includes a first rotating shaft 322, a sleeve 324, a coil spring 325, a first limiting plate 321 for limiting one end of the model transfer cart 1, and a limiting frame 323 for preventing the first limiting plate 321 from rotating in the opposite direction. The sleeve 324 is fixedly connected to the limiting frame 323, the first limiting plate 321 is fixedly connected to the first rotating shaft 322, the first rotating shaft 322 is rotatably connected inside the sleeve 324, the two ends of the coil spring 325 abut against the first rotating shaft 322 and the sleeve 324 respectively, and the limiting frame 323 is fixedly installed on the side wall of the loading and unloading channel 31. The second limiting component 33 includes a rotating disk 332, a second rotating shaft 333, a connecting rod 335, a first transmission gear 334 meshing with the second transmission gear 74, and a second limiting plate 331 for limiting the other end of the model transfer cart 1. The first transmission gear 334 and the rotating disk 332 are respectively fixedly installed at the upper and lower ends of the second rotating shaft 333. The second rotating shaft 333 is rotatably connected to the surface of the frame 3. One end of the connecting rod 335 is hinged to the eccentric position of the rotating disk 332, and the other end of the connecting rod 335 is hinged to the second limiting plate 331. The second limiting plate 331 is slidably connected in the guide hole opened in the side wall of the loading and unloading channel 31.

[0017] In this embodiment, during the process of pushing the mannequin transfer cart 1 into the loading and unloading channel 31, the spring force of the coil spring 325 can be overcome to rotate the first limiting plate 321, so that the first limiting plate 321 can avoid the mannequin transfer cart 1. After the mannequin transfer cart 1 passes the first limiting plate 321, the elastic deformation of the coil spring 325 drives the first limiting plate 321 to rotate in the opposite direction around the axis of the first rotating shaft 322 until the side of the first limiting plate 321 away from the mannequin transfer cart 1 contacts the limiting frame 323. The limiting frame 323 is used to limit the first limiting plate 321. It should be noted that at this time, there is a gap between the first limiting plate 321 and the mannequin transfer cart 1. The operator needs to pull the mannequin transfer cart 1 in the opposite direction to move it a certain distance so that the mannequin transfer cart 1 contacts the first limiting plate 321 to prevent the second limiting plate 331 from interfering with the mannequin transfer cart 1. When the rotating roller 73 controls the rotating disk 332 to rotate via the second transmission gear 74 and the first transmission gear 334, the rotating disk 332 controls the second limiting plate 331 to extend out of the guide hole by the connecting rod 335 to fit against the surface of the model transfer carriage 1, so that the second limiting plate 331 can be limited from the other end of the model transfer carriage 1, thus achieving the function of automatic limiting by using the power of the belt conveyor 7.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
