Description

Technical Field

[0001] This invention relates to the technical field of specialized equipment for automated processing of automotive frame parts, and in particular to a fully automated material winding device. Background Technology

[0002] The frame pin is a core metal connector in automobile frame assembly. After the frame is welded, it undergoes a rust-proofing process. The lug area of ​​the frame pin needs to be coated with protective paint, but critical assembly areas such as the pin mating surface and threaded sections must not be contaminated with paint. If paint is applied, it can cause assembly jamming, excessive clearance, and accelerated wear of parts. Therefore, physical shielding protection must be applied to the non-painted areas of the frame pin before painting.

[0003] Currently, the shielding and protection of vehicle frames before painting relies entirely on manual operation, with no dedicated automated wrapping equipment in the industry. Operators take flexible masking materials such as newspapers and plastic wrapping film, manually cut and fold them, and then manually wrap and press them onto the areas of the frame to be shielded. After each piece is wrapped, it is manually transferred to the painting station. The entire production line relies on multiple workers to continuously repeat the masking operation, with no mechanical positioning, transfer, or wrapping auxiliary structures throughout the entire process.

[0004] The manual wrapping method lacks standardized mechanical support structures. First, the frame pin conveyor lacks a centering and correction mechanism, making it easy for workpieces to shift and sway during transport, and making it impossible to standardize workstations. Second, manual clamping and transfer can easily squeeze and scratch the frame pins, and there is no non-destructive positioning and transfer structure. Third, manual winding lacks a unified movement trajectory, resulting in large differences in the number of winding layers, tightness, and coverage boundaries, and inadequate shielding can easily lead to paint seepage. Fourth, there is no automatic film cutting and continuous conveying structure, making the single-piece processing cycle unstable, and the manual wrapping process becomes a bottleneck for production line efficiency during mass production. Fifth, the repetitive manual operation is labor-intensive, resulting in poor consistency in wrapping quality and a persistently high rate of defective product coating. Summary of the Invention

[0005] This application provides a fully automatic material wrapping device, which realizes the unmanned and automated operation of the entire process of vehicle frame pin shielding and wrapping, completely replaces the manual wrapping process, greatly shortens the processing time of a single piece, stabilizes the production line operation rhythm, and breaks through the production capacity bottleneck caused by manual operation.

The entire operation requires no manual intervention, the processing time per piece is greatly shortened, the operation cycle is stable and controllable, effectively eliminating the efficiency bottleneck caused by the manual wrapping process and improving the overall capacity of the painting production line.

[0016] 2. With this device, operators only need to perform auxiliary tasks such as equipment monitoring and material replenishment, eliminating the need for repetitive, high-intensity movements such as bending over, reaching out, and wrapping, significantly reducing labor burden. Furthermore, manual packaging operations that previously required multiple personnel can now be completed by a smaller team working with the equipment, optimizing production line staffing and reducing labor costs.

[0017] 3. This device employs a mechanically controlled winding method. The number of winding layers, tension, coverage position, and boundary accuracy are all precisely controlled through preset parameters or sensor feedback, eliminating individual differences and random errors caused by manual operation. The wrapped newspaper adheres tightly and has neat edges, effectively preventing paint from seeping into the area to be shielded during the coating process.

[0019] 5. As an automated solution for the pre-treatment stage of coating, this device can work in conjunction with upstream welding stations and downstream spraying equipment, providing key node equipment support for building a fully automated coating production line, and has high industrial promotion value.

[0020] 6. To further optimize the function of conveying frame pins of different specifications with offset and centering difficulties, the present invention also sets up a symmetrical adjustable positioning base, an adjusting screw and a positioning plate assembly, with threaded adjustment of the spacing, and an elastic buffer layer to achieve centering and correction of frame pins of various diameters throughout the conveying process, eliminating workpiece shaking and misalignment, and laying the foundation for subsequent precise processing.

[0021] 7. To further optimize the function of accurately locking and clamping the workpiece after the frame pin is delivered to the position, the present invention also sets up a photoelectric induction cylinder-driven arc-shaped clamping block, with independent cylinders on both sides clamping synchronously, and the arc-shaped contact surface is evenly stressed, so as to realize automatic clamping of the workpiece upon arrival, without indentation damage, and stable locking of the winding front station.

[0022] 8. To further optimize the function of workpiece transfer and prevent workpiece clamping and trajectory deviation, the present invention also includes a dual electromagnet magnetic attraction transfer assembly, a transfer slide plate with a limiting groove and a first electric telescopic rod, which enables non-contact magnetic attraction transfer and the limiting groove constrains the sliding path, so as to realize workpiece transfer without damage and accurate delivery to the winding station.

[0023] 9.

[0024] 10. To further optimize the function of uneven wrapping and incomplete coverage by single winding motion, the present invention also sets up a motor gear ring driven rotating sleeve, a fourth telescopic rod lifting structure, and multiple sets of limit wheels radially supporting sleeves to achieve longitudinal lifting + circumferential rotation composite winding, so that the film material uniformly and fully covers the shielding area.

[0025] 11.

The guide sleeve constrains the cutting path, which is used to achieve automatic and accurate film cutting after wrapping, with a smooth cut, without the need for secondary manual cutting.

[0026] 12. To further optimize the function of intermittent operation and inability to produce continuously in a single workstation, the present invention also sets up a first and second crawler conveyor belt arranged in parallel, and a magnetic suction component for bidirectional transfer of workpieces, so as to realize synchronous cycle of loading, winding and unloading, and uninterrupted continuous automated operation of the equipment.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0029] This invention discloses a fully automatic material winding device. The device can automatically complete the feeding, winding and cutting of newspaper in the area to be shielded on the frame pin, replacing manual operation, thereby improving the work efficiency of the pre-coating process, reducing the intensity of manual labor, and ensuring that the tightness of the shielding wrap, the coverage boundary and the sealing effect are uniform and consistent, ultimately improving the coating quality and product yield.

[0030] like Figure 1 and Figure 2 As shown, the system includes a support frame 1; a first tracked conveyor belt 2 is mounted on the top of the support frame 1; the frame pins enter the sensing platform 3 through the feed inlet of the first tracked conveyor belt 2. Specifically, several positioning bases 4 are fixedly installed on both sides of the support frame 1. The positioning base 4 has threaded holes inside, and an adjusting screw 5 is threaded into the threaded holes. An adjusting handle is provided at the outer end of the adjusting screw 5, and a rotatable movable block 6 is provided at the inner end of the adjusting screw 5. The movable block 6 is slidably mounted inside the positioning slide rail 7. A positioning plate 8 is provided at the inner end of the positioning slide rail 7. Two positioning plates 8 are symmetrically arranged about the forward center axis of the first tracked conveyor belt 2, and the spacing of the positioning plates 8 can be adaptively adjusted according to the adjusting screw 5 to accommodate frame pins of different diameters and to ensure the stability of the frame pins during the conveying process.

[0031] To address the industry pain point of misalignment and unstable positioning of frame pins of different specifications, the device is equipped with an adaptively adjustable positioning mechanism. Positioning bases 4, symmetrically arranged on both sides of the support frame 1, serve as a fixing carrier. Utilizing the threaded engagement between the internal threaded holes of the positioning bases 4 and the adjusting screw 5, the screw can be driven to rotate and extend / retract using the external adjusting handle. The rotatable movable block 6 at the inner end of the screw slides directionally along the positioning slide rail 7, thereby synchronously adjusting the spacing of the two symmetrically distributed positioning plates 8, maintaining the workpiece centered with the conveyor belt's central axis as the reference throughout the entire process.

[0032] This mechanical adjustment structure can precisely adapt to frame pin workpieces of different diameters, correcting workpiece position deviations from the source of conveying and eliminating problems such as workpiece shaking, offset, and misalignment. It lays a solid positioning foundation for the fully automated operation of subsequent newspaper feeding, wrapping, and precise cutting, enabling the entire process to operate smoothly, accurately, and continuously.

[0033] like Figure 1 and Figure 3 As shown, the sensing platform 3 is further positioned at the output end of the first track conveyor belt 2. Fixed blocks 9 are fixedly installed on both sides of the sensing platform 3, and two synchronously moving clamping blocks 10 are positioned directly above the sensing platform 3. The clamping blocks 10 are driven by cylinders 11 mounted on the fixed blocks 9. When the frame pin moves to the position of the fixed blocks 9, the photoelectric sensor 12 on the side of the fixed blocks 9 is triggered. The photoelectric sensor 12 then sends a signal and the controller controls the cylinder 11 to move, driving the clamping blocks 10 to move closer until the inner surface arc of the clamping blocks 10 fits against the two opposite sides of the frame pin, thereby locking the frame pin in the preset position on the sensing platform 3.

[0034] Unlike traditional rigid clamping structures, the arc-shaped contact surface can evenly distribute the clamping force, eliminating the problems of sharp corner squeezing and localized force concentration, completely preventing damage such as indentations, deformation, and scratches on the frame pin surface, and protecting the integrity of the workpiece substrate.

[0035] like Figure 3 and Figure 4As shown, a transfer platform 13 is provided on the other side of the sensing platform 3. The transfer platform 13 has a rectangular structure and is located on one side of the sensing platform 3. A magnetic conveying assembly 14 is fixedly installed on the side of the transfer platform 13 adjacent to the sensing platform 3. A positioning area is provided on the transfer platform 13. A limiting groove 15 is provided in the positioning area of ​​the transfer platform 13. A slide plate 16 is provided inside the limiting groove 15. A first electric telescopic rod 17 for driving the slide plate 16 is provided inside the limiting groove 15. Under the action of the magnetic conveying assembly 14, the frame pin positioned at the preset work station is magnetically attracted and conveyed to the slide plate 16 in the positioning area. Then, under the driving action of the first electric telescopic rod 17, the slide plate 16 is pushed to move in the direction of the winding area on the other side of the sensing platform inside the limiting groove 15.

[0036] After the frame pin is precisely clamped and positioned, the magnetic transfer assembly 14 starts working, using a non-contact magnetic adsorption method to smoothly transfer the frame pin from the preset workstation to the positioning area of ​​the transfer platform 13, so that the workpiece is initially placed above the slide plate 16. Then, the limiting groove 15 provides a directional movement track for the slide plate 16, constraining its movement trajectory and preventing problems such as lateral deviation and swaying. Then, the built-in first electric telescopic rod 17 provides a stable linear driving force, pushing the slide plate 16 to slide precisely along the limiting groove 15, and smoothly pushing the frame pin to the winding operation area on the other side of the sensing platform 3.

[0037] Unlike the rigid clamping and transfer of traditional mechanical grippers, magnetic adsorption provides uniform force and non-contact compression, completely avoiding clamping marks, wear, and deformation during frame pin transfer, and comprehensively protecting the appearance and structural integrity of the workpiece. Furthermore, the limiting groove 15 forms a bidirectional trajectory constraint on the slide plate 16, preventing angular deviations and positional misalignments during workpiece transfer, ensuring that the workpiece arrives at the winding area in a completely consistent position each time, laying the foundation for standardized winding operations.

[0038] like Figure 4 The magnetic transfer assembly 14 includes a stand 1401 and a linear motor fixed on the stand 1401. A guide rail 1402 is provided on the top of the stand 1401. A guide slider 1403 is provided inside the guide rail 1402. The guide slider 1403 moves along the direction of the guide rail 1402 under the action of the linear motor. The bottom of the guide slider 1403 is fixedly connected to the integrated plate 1405 through a connector 1404. Two electromagnets 1406 are provided on the bottom of the integrated plate 1405. The electromagnets 1406 are raised and lowered by a second electric telescopic rod on the integrated plate 1405, so that the electromagnets 1406 contact the top of the frame pin and the frame pin is transferred by the linear motor.

[0039] In actual operation, after the frame pin is locked in place, the second electric telescopic rod extends precisely, pushing the electromagnet 1406 downward to adhere to the top end face of the frame pin. Upon energization, a stable magnetic force is generated to firmly attract the workpiece. After adhesion and attraction are complete, the linear motor starts, driving the slider to slide smoothly along the guide rail 1402, causing the integrated plate 1405 and the attracted frame pin to be precisely transferred as a whole, ultimately transferring the workpiece smoothly to the positioning area of ​​the transfer platform 13. This split-type lifting and translating structure separates and controls the magnetic adhesion and horizontal transfer actions, executing them step-by-step with precise coordination. This completely solves the problems of unstable adhesion and large displacement deviation in traditional integrated transfer structures, achieving standardization and high precision throughout the entire workpiece transfer process.

[0040] like Figure 4 As shown, a mounting frame 18 is provided in the winding area on the other side of the transfer platform 13. The mounting frame 18 is positioned opposite to the upright frame 1401 of the magnetic conveying component 14 and is located at the sliding output position of the slide plate 16. A top plate 19 is fixedly installed on the top of the mounting frame 18. A third electric telescopic rod 20 is provided at the center of the top plate 19, and the bottom output end of the third electric telescopic rod 20 is connected to a pressure block 21. The pressure block 21 is coaxially arranged with the frame pin on the slide plate 16 directly below, and realizes the fixing function of the frame pin. After the frame pin is fixed, the frame pin is first coated with film and then cut by passing through the winding module 22 and the cutting mechanism 23 on the mounting frame 18 in sequence.

[0041] After the slide plate 16 precisely pushes the frame pin into the winding operation area, the third electric telescopic rod 20 descends vertically, driving the pressure block 21 to press the top of the frame pin, locking the workpiece position vertically and completely restricting the workpiece's vertical movement, radial offset, and angular deflection, ensuring the workpiece is firmly fixed in the standard operating position. After completing the high-precision locking, the equipment, relying on the winding module 22 and cutting mechanism 23 integrated in the mounting frame 18, performs the operation according to the sequence of processes, first completing the uniform winding and wrapping process of newspaper film, and then automatically cutting off the excess film material.

[0042] like Figure 5 and Figure 6As shown, the winding module 22 includes a vertical rail 2201 fixed on the mounting frame 18. A connecting block 2202 is slidably arranged on the vertical rail 2201. The connecting block 2202 slides up and down through the fourth electric telescopic rod 2203 on the top plate 19. A fixed sleeve 2204 is fixedly installed on one side of the connecting block 2202. A rotating sleeve 2205 is rotatably arranged inside the fixed sleeve 2204. A fixed ring 2206 is arranged at the bottom of the rotating sleeve 2205. The fixed ring 2206 is coaxially arranged with the pressure block 21 and the frame pin. A rotatable shaft 2207 is arranged at the bottom of the fixed ring 2206. A winding film 2208 is wound on the rotating shaft 2207. During the winding process, the winding film 2208 moves from bottom to top longitudinally. At the same time, it makes a circular motion around the axis of the frame pin by rotating the sleeve 2205, so as to achieve uniform winding of the area to be shielded on the frame pin.

[0043] During operation, the rotating shaft 2207, with the wrapping film 2208 wound up, moves synchronously with the rotating sleeve 2205. The equipment simultaneously activates a dual-dimensional motion mode: on one hand, the fourth electric telescopic rod 2203 drives the entire wrapping structure to move longitudinally at a uniform speed from bottom to top; on the other hand, the rotating sleeve 2205 drives the wrapping film 2208 to perform a precise circular motion around the frame pin axis. The two motions are synchronously coupled and precisely coordinated, allowing the wrapping film 2208 to adhere layer by layer and evenly to the area of ​​the frame pin to be shielded. The entire process requires no manual intervention. Relying on mechanical composite motion to replace the traditional single-circle wrapping method, it perfectly adapts to the shielding and wrapping needs of various frame pins, achieving standardized wrapping operations with full coverage and no blind spots.

[0044] like Figure 6 As shown, a gear ring 2209 is coaxially fixedly mounted on the outer side of the rotating sleeve 2205. A gear 22010 meshes with the outer side of the gear ring 2209. The central axis of the gear 22010 is coaxially connected to the output end of the second drive motor fixed on the fixed sleeve 2204, which is used to drive the rotating sleeve 2205.

[0045] Furthermore, several L-shaped brackets 24 are fixedly installed on the fixed sleeve 2204. Limiting wheels 25 are provided on the L-shaped brackets 24. The limiting wheels 25 are arranged at equal angles around the central axis of the rotating sleeve 2205, and roll between the limiting wheels 25 and the inner ring of the rotating sleeve 2205. The limiting wheels 25 and the inner ring of the rotating sleeve 2205 are assembled in a rolling fit, which retains the free rotational motion characteristics of the rotating sleeve 2205 while achieving real-time radial constraint and limitation. During the winding operation, the second drive motor drives the gear 22010 and the gear ring 2209 to drive the rotating sleeve 2205 to rotate at high speed, performing circumferential winding motion. At this time, multiple sets of equally angled limiting wheels 25 synchronously roll against the inner ring of the sleeve, providing uniform support to the rotating sleeve 2205 from all radial directions. This structure effectively compensates for the slight meshing clearance in the gear 22010 and gear ring 2209 meshing transmission, and counteracts problems such as radial offset and eccentric sway caused by high-speed rotation. It always locks the coaxiality of the rotating sleeve 2205 and the frame pin, and precisely coordinates with the longitudinal lifting and feeding motion, so that the composite winding motion trajectory always remains in a standard and constant state, providing a key structural guarantee for uniform and deviation-free shielding winding operations.

[0046] After the wrapping operation is completed, the cutting mechanism 23 cuts the wrapping film 2208. The cutting mechanism 23 includes a fixing plate fixed to the bottom of the connecting block 2202. A fifth electric telescopic rod is fixedly installed on the fixing plate. A cutting blade is provided at the bottom of the fifth electric telescopic rod. When the frame pin is evenly wrapped, the wrapping module 22 pauses its operation, the fifth electric telescopic rod quickly extends, and drives the blade to descend and cut the wrapping film 2208, completing the shaping and cutting of the workpiece shielding wrapping.

[0047] like Figure 1 As shown, after the frame pin is wound, the bottom slide plate 16 returns to its original position, conveying it to the area below the magnetic conveyor. The rear magnetic conveyor picks up the wound frame pin and transfers it to the second tracked conveyor belt, which is located on one side of the transfer platform 13. The second tracked conveyor belt then transports the pin to the subsequent packaging station. Simultaneously, the front magnetic conveyor assembly 14 picks up the frame pin to be wound and transfers it to the slide plate 16. The slide plate 16 then transfers the frame pin to be wound to the winding area for winding. The above actions are repeated sequentially to achieve continuous automated winding of the frame pin.

[0048] Working principle: First, the frame pins to be shielded are fed into the first track conveyor belt 2 at the top of the support frame 1 by the upstream welding process, and the automated processing flow is officially started. Before processing, the operator can rotate the adjustment handle on the outside of the adjusting screw 5. The screw thread engages with the positioning plates 8 on both sides to adjust the spacing to match the diameter of the frame pin being produced. The symmetrical positioning plates 8 continuously correct the workpiece in the conveyor, ensuring that the frame pin is transported smoothly along the central axis of the conveyor belt, thus avoiding the problems of deviation and shaking from the source.

[0049] Then, the frame pin is continuously transported to the sensing platform 3 station by the track. After the photoelectric sensor 12 on the side of the fixing block 9 detects the workpiece, it outputs an electrical signal. The equipment controller synchronously controls the independent cylinders 11 on both sides to extend synchronously. The cylinders 11 drive the inner arc surface clamping blocks 10 to move towards each other, evenly wrapping the side wall of the frame pin, locking the workpiece in the standard processing station of the sensing platform 3 without squeezing damage.

[0050] Subsequently, the magnetic transfer assembly 14 starts the transfer process. The second electric telescopic rod drives the double electromagnets 1406 at the bottom of the integrated plate 1405 to descend vertically. After the electromagnets 1406 are in contact with the top surface of the frame pin, they are energized to generate a stable magnetic force to firmly attract the workpiece. The linear motor drives the guide slider 1403 to move along the guide rail 1402 to transfer the frame pin without damage to the slide plate 16 in the positioning area of ​​the transfer platform 13. The electromagnets 1406 are de-energized to complete the workpiece unloading.

[0051] Next, the first electric telescopic rod 17 in the limiting groove 15 extends, pushing the slide plate 16 to slide linearly along the limiting groove 15, smoothly pushing the frame pin to the working position directly below the winding area. The lateral limiting block restricts the slide plate 16 from overtravel, and the buffer pad buffers the impact force when it reaches the position.

[0052] Subsequently, the winding area fixing mechanism activates the locking action, and the third electric telescopic rod 20 at the center of the top plate 19 descends vertically. The coaxial pressure block 21 presses the top of the frame pin, forming a bidirectional clamping action with the lower slide plate 16, completely eliminating axial movement and radial eccentricity of the workpiece, and ensuring that the workpiece is coaxial with the winding module 22.

[0053] After the workpiece is locked, the winding module 22 initiates a two-dimensional composite winding motion: the second drive motor, through gear 22010 meshing with gear ring 2209, drives the rotating sleeve 2205 to rotate uniformly around the frame pin axis, while the fourth electric telescopic rod 2203 drives the connecting block 2202 to rise uniformly from bottom to top along the vertical rail 2201; the winding film 2208 on the rotating shaft 2207 moves synchronously with the sleeve's circumference and longitudinal feed, uniformly covering the frame pin shielding area layer by layer, and multiple sets of L-shaped bracket limit wheels 25 continuously adhere to the inner ring of the sleeve for rolling support, offsetting the high-speed rotation eccentricity gap and maintaining the winding coaxiality. After the preset number of winding turns is completed, the winding module 22 pauses its operation, the cutting mechanism 23 starts the cutting process, the fifth electric telescopic rod extends downward, and the single-sided oblique cutting blade descends smoothly along the guide sleeve, cutting the winding film 2208 material in one go, completing the shielding wrapping and shaping.

[0054] Subsequently, the third electric telescopic rod 20 drives the pressure block 21 to move upward and release the workpiece, the first electric telescopic rod 17 pulls the slide plate 16 to reset, the magnetic suction conveyor assembly 14 starts again, attracts the frame pin that has been wound, and moves it horizontally to the second track conveyor belt, from which it is conveyed to the downstream spraying station.

[0055] At the same time, the magnetic conveyor component 14 synchronously grabs the newly arrived frame pins to be wound on the sensing platform 3, repeating the entire process of transfer, winding, and cutting. The entire set of equipment relies on photoelectric sensing, multiple sets of electric telescopic rods, and drive motors working together to perform the feeding, transfer, winding, and unloading processes alternately and synchronously, continuously completing the fully automatic shielded winding of the frame pins without any manual intervention, realizing continuous automated processing on the production line.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
