Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automatic feeding device for automotive parts spraying. Background Technology

[0002] In the automotive parts manufacturing industry, stamping is a crucial step in forming sheet materials. During stamping, efficient material transport is essential for the smooth operation of the entire production process.

[0003] However, existing feeding mechanisms are not compact enough, with a loose layout of functional modules and a lack of tight integration between components. For example, the feeding mechanism places the feeding track and positioning device in different areas, connected by a long transmission path. This dispersed layout not only occupies a large amount of horizontal space in the workshop, but also increases the overall operating time of the equipment and reduces production efficiency due to material waiting and transfer during the transmission process. Utility Model Content

[0004] The main purpose of this utility model is to propose an automatic feeding device for automotive parts spraying, which aims to solve the technical problem of slow material conveying efficiency caused by insufficient compactness of the feeding mechanism in the prior art.

[0005] To achieve the above objectives, this utility model proposes an automatic feeding device for automotive parts painting, comprising: A frame, wherein a feed inlet is provided on one side of the frame and a discharge outlet is provided on the side of the frame opposite to the feed inlet, and the feed inlet is provided with a carrier for placing materials; A feeding mechanism is movably disposed inside the frame, and the feeding mechanism includes a clamping assembly and a multi-axis motion module connected to the clamping assembly; The discharge mechanism is located between the carrier and the loading mechanism. The discharge mechanism includes a loading platform and a discharge drive module connected to the loading platform. The loading platform can move relative to the discharge port under the drive of the discharge drive module to extend out of the frame and retract into the frame.

[0006] In some embodiments, the multi-axis motion module includes a Y-axis assembly, which includes two Y-axis guide rails respectively disposed on opposite sides of the top of the frame. The two ends of any Y-axis guide rail face the feed port and the discharge port respectively. The two Y-axis guide rails are slidably connected to a Y-axis moving frame, and the Y-axis moving frame is connected to the clamping assembly.

[0007] In some embodiments, the multi-axis motion module further includes a Z-axis assembly disposed on the Y-axis moving frame. The Z-axis assembly includes a Z-axis drive module disposed on the Y-axis moving frame and a Z-axis moving frame connected to the Z-axis drive module. The clamping assembly is connected to the bottom of the Z-axis moving frame.

[0008] In some embodiments, the clamping assembly includes a plurality of suction cups.

[0009] In some embodiments, the discharge drive module includes two discharge guide rails respectively disposed on both sides of the loading platform parallel to the Y-axis guide rail. The two discharge guide rails are located below the Y-axis guide rail. The end of any discharge guide rail near the feed inlet extends toward the feed inlet. The frame is provided with discharge sliders on both sides parallel to the discharge guide rails. The two discharge guide rails are slidably connected to the two discharge sliders respectively.

[0010] In some embodiments, the loading platform is provided with multiple sets of positioning fixtures for fixing materials and positioning drive components connected to the positioning fixtures.

[0011] In some embodiments, the loading platform is provided with a plurality of clearance holes corresponding to the positioning fixture. The positioning fixture includes a clamping part and a fixing part. The clamping part protrudes from the surface of the loading platform through the clearance holes. A plurality of positioning driving members are disposed at the bottom of the loading platform, and the fixing part is connected to the positioning driving members.

[0012] In some embodiments, the multiple sets of positioning fixtures include a Y-direction positioning fixture disposed in the middle of the loading platform, and at least two X-direction positioning fixtures respectively disposed on both sides of the loading platform near the discharge guide rail, wherein at least four sets of the Y-direction positioning fixtures are provided.

[0013] In some embodiments, an alarm is provided on the top of the rack.

[0014] In some embodiments, the bottom of the frame is provided with wheels.

[0015] This invention improves the compactness of the automatic feeding device for automotive parts painting by opening inlet and outlet ports on opposite sides of the frame, and by setting up loading and unloading mechanisms inside. This avoids wasted space, shortens the material flow path, and enables efficient material transfer within a limited space. In addition, the multi-axis motion module is movably installed inside the frame, allowing for flexible movement and high-precision control. This enables the loading mechanism to quickly and accurately complete the grabbing and transfer of materials. Driven by the unloading drive module, the loading platform of the unloading mechanism can promptly send materials out of the frame. Combined with the material picking action of the robot in the next process, seamless material connection is achieved, greatly shortening the material transfer time and improving the efficiency of the entire production process.

[0021] Please refer to Figure 1 and Figure 2 This utility model provides an automatic feeding device 100 for automotive parts painting, comprising: The frame 200 has a feed inlet 210 on one side and a discharge outlet 220 on the side opposite to the feed inlet 210. The feed inlet 210 is provided with a carrier 230 for placing materials. The feeding mechanism 300 is movably located inside the frame 200. The feeding mechanism 300 includes a clamping component 310 and a multi-axis motion module 320 connected to the clamping component 310. The discharge mechanism 400 is located between the carrier 230 and the loading mechanism 300. The discharge mechanism 400 includes a loading platform 410 and a discharge drive module 420 connected to the loading platform 410. The loading platform 410 can move relative to the discharge port 220 under the drive of the discharge drive module 420 to extend out of the frame 200 and retract into the frame 200.

[0022] The frame 200 serves as the main support for the entire mechanism, with an inlet 210 and an outlet 220 on its two sides, respectively. This allows materials to flow in an orderly manner along a fixed path, avoiding space waste and inefficiency caused by chaotic paths. The frame 200 can be made of materials such as aluminum alloy or steel. Specifically, the material can be determined according to actual needs, and this utility model does not impose any limitations.

[0023] In this embodiment, the material is rectangular. The carrier 230 set at the feed inlet 210 is a component specifically used to place the material. Its shape can be rectangular to ensure that the material remains stable on the carrier 230 while waiting to be fed, and will not shift or fall off.

[0024] The loading mechanism 300 is movably located inside the frame 200 and consists of a clamping component 310 and a multi-axis motion module 320. The clamping component 310 can be a suction cup or a gripper structure, depending on actual needs; this invention does not impose any limitations. The multi-axis motion module 320 provides the clamping component 310 with a flexible movement trajectory, enabling it to move within the cabinet and accurately complete the action of grabbing materials from the carrier 230 and transferring them to the loading platform 410.

[0025] The discharge mechanism 400 is located between the carrier 230 and the loading mechanism 300. It can also be understood as being located in the middle of the height direction. It includes a loading platform 410 and a discharge drive module 420. The loading platform 410 carries materials conveyed from the carrier 230 for the next process robot to grasp. The discharge drive module 420 provides power for the movement of the loading platform 410, enabling it to extend out of and retract into the frame 200 relative to the discharge port 220. The transmission method of the discharge drive module 420 can be selected according to actual needs, such as screw drive or belt drive, as long as it can achieve linear movement of the loading platform 410. This invention does not impose any limitations on this method.

[0026] In operation, the material is first placed on the carrier 230 at the feed inlet 210, completing the pre-loading preparation. At this time, the multi-axis motion module 320 of the loading mechanism 300 receives a working command and drives the clamping assembly 310 to move above the carrier 230, accurately gripping the material on the carrier 230. Subsequently, the multi-axis motion module 320 drives the clamping assembly 310, holding the material, to move along a set path above the loading platform 410 of the discharge mechanism 400, and smoothly places the material on the loading platform 410. During this process, the high-precision control of the multi-axis motion module 320 ensures accurate material positioning and avoids collisions with other components. After the material is placed on the loading platform 410, the discharge drive module 420 starts working, driving the loading platform 410 to move towards the discharge port 220 until the loading platform 410 extends beyond the frame 200. At this point, the robotic arm of the next process can easily remove the material from the loading platform 410, completing the material handover. After the material is removed, the discharge drive module 420 drives the loading platform 410 to retract into the frame 200, awaiting the next material placement. Simultaneously, the loading mechanism 300 actuates again, grabbing new material from the carrier 230, repeating the above workflow to achieve continuous material loading and unloading.

[0027] This invention improves the compactness of the automatic feeding device 100 for automotive parts painting by opening inlet 210 and outlet 220 on opposite sides of the frame 200, and by setting up feeding mechanism 300 and discharging mechanism 400 inside, avoiding space waste, shortening the material flow path, and achieving efficient material transfer within a limited space. In addition, the multi-axis motion module 320 is movably installed inside the frame 200, which can move flexibly and be controlled with high precision, enabling the feeding mechanism 300 to quickly and accurately complete the gripping and transfer of materials. The loading platform 410 of the discharging mechanism 400, driven by the discharging drive module 420, can promptly send materials out of the frame 200, and in conjunction with the material picking action of the next process robot, achieves seamless material connection, greatly shortens the material transfer time, and improves the efficiency of the entire production process.

[0028] Please refer to Figure 2 and Figure 3 The multi-axis motion module 320 includes a Y-axis assembly 321. The Y-axis assembly 321 includes two Y-axis guide rails 3211 respectively disposed on opposite sides of the top of the frame 200. The two ends of any Y-axis guide rail 3211 face the feed port 210 and the discharge port 220 respectively. The two Y-axis guide rails 3211 are slidably connected to a Y-axis moving frame 3212, and the Y-axis moving frame 3212 is connected to a clamping assembly 310.

[0029] Two Y-axis guide rails 3211 are respectively set on opposite sides of the top of the frame 200. The symmetrical installation provides a stable support foundation for the entire Y-axis assembly 321, which can effectively disperse the force generated by the Y-axis moving frame 3212 and the clamping assembly 310 during the movement, and ensure the stability of operation.

[0030] Both ends of any Y-axis guide rail 3211 face the inlet 210 and outlet 220 respectively, so that the movement trajectory of the Y-axis moving frame 3212 can accurately cover the material transfer path from the inlet 210 to the outlet 220. The Y-axis moving frame 3212 is slidably connected to the two Y-axis guide rails 3211, and adopts a slider and guide rail cooperation structure to ensure the smoothness of the displacement and positioning accuracy of the Y-axis moving frame 3212.

[0031] Once the material is placed on the carrier 230 at the inlet 210, the control system issues a command, and the Y-axis assembly 321 begins operation. The drive unit drives the Y-axis moving frame 3212 to slide along the Y-axis guide rail 3211. Since the two ends of the Y-axis guide rail 3211 face the inlet 210 and the outlet 220 respectively, the Y-axis moving frame 3212 can precisely move from its initial position, carrying the clamping assembly 310, above the carrier 230 at the inlet 210. After the clamping assembly 310 completes gripping the material, the Y-axis moving frame 3212 moves again along the Y-axis guide rail 3211 towards the outlet 220, smoothly conveying the clamping assembly 310 holding the material above the loading platform 410 of the discharge mechanism 400. After the material is placed on the loading platform 410, the Y-axis moving frame 3212 drives the clamping assembly 310 to return to the vicinity of the feed port 210 along the Y-axis guide rail 3211, waiting for the next gripping command, thereby realizing the orderly transmission of the material in the Y-axis direction.

[0032] The two Y-axis guide rails 3211 of this utility model are installed at the top of the frame 200, making full use of the unused space at the top of the frame 200 without increasing the size of the frame 200, thus further enhancing the compactness of the mechanism. The sliding motion trajectory of the Y-axis moving frame 3212 along the Y-axis guide rails 3211 is precise and stable, reducing the offset and shaking of the clamping assembly 310 during the movement process, ensuring that the material can be quickly and accurately transferred from the feed port 210 to the discharge port 220, shortening the material transfer time and improving the material transfer efficiency.

[0033] Please continue to refer to this. Figure 2 and Figure 3 The multi-axis motion module 320 also includes a Z-axis assembly 322 disposed on the Y-axis moving frame 3212. The Z-axis assembly 322 includes a Z-axis drive module 3222 disposed on the Y-axis moving frame 3212 and a Z-axis moving frame 3221 connected to the Z-axis drive module 3222. A clamping assembly 310 is connected to the bottom of the Z-axis moving frame 3221.

[0034] The Z-axis assembly 322 is mounted on the Y-axis moving frame 3212. This stacked structure design makes full use of the space of the Y-axis moving frame 3212, making the entire multi-axis motion module 320 more compact in structure, avoiding the waste of space caused by the dispersed setting of each axis assembly, and improving the overall compactness of the automatic feeding device 100 for automotive parts painting.

[0035] Z-axis assembly 322 includes Z-axis moving frame 3221 and Z-axis drive module 3222. Z-axis drive module 3222 is connected to Z-axis moving frame 3221 and provides power for the movement of Z-axis moving frame 3221. Z-axis drive module 3222 can be a combination of servo motor and synchronous belt. The bottom of Z-axis moving frame 3221 is directly connected to clamping assembly 310. The connection can be made by bolts, ensuring the stability of clamping assembly 310 during movement and facilitating subsequent individual disassembly and maintenance.

[0036] When the Y-axis moving frame 3212, carrying the Z-axis assembly 322 and the clamping assembly 310, moves above the feed inlet 210 carrier 230, the Z-axis drive module 3222 begins to operate. Driven by the Z-axis drive module 3222, the Z-axis moving frame 3221 moves downward, causing the clamping assembly 310 connected to its bottom to approach the material on the carrier 230 until the clamping assembly 310 reaches a suitable gripping position. Subsequently, the clamping assembly 310 grips the material. After gripping, the Z-axis drive module 3222 drives the Z-axis moving frame 3221 upward, lifting the material to a suitable height to prevent the material from colliding with other components during its movement with the Y-axis moving frame 3212. When the Y-axis moving frame 3212 conveys the material to the loading platform 410 of the discharge mechanism 400, the Z-axis drive module 3222 drives the Z-axis moving frame 3221 to move downwards, causing the clamping assembly 310 to bring the material closer to the loading platform 410. Once the material reaches the appropriate position, the clamping assembly 310 releases the material and places it on the loading platform 410. Finally, the Z-axis drive module 3222 drives the Z-axis moving frame 3221 upwards, returning it to its initial height, preparing for the next gripping action. In this way, the Z-axis assembly 322, through its vertical lifting motion, combined with the horizontal movement of the Y-axis assembly 321, achieves precise material transfer within the frame 200.

[0037] The horizontal movement of the Z-axis assembly 322 and the Y-axis assembly 321 works in conjunction. The vertical movement provided by the Z-axis assembly 322 allows the clamping assembly 310 to move freely within the cabinet, meeting the needs of gripping and placing materials at different heights and expanding the flexibility and versatility of the automatic loading device 100 for automotive parts painting. Furthermore, the Z-axis drive module 3222 drives the Z-axis moving frame 3221 to move rapidly and with precise positioning, shortening the vertical movement time of the clamping assembly 310 and improving the efficiency of material gripping and placement. Simultaneously, the coordinated work of the Z-axis assembly 322 and the Y-axis assembly 321 reduces redundant movements during material transfer, making the entire loading process smoother and further improving the overall efficiency of the production line. Finally, regarding material safety, the Z-axis assembly 322 can precisely control the descent and ascent height of the clamping assembly 310, avoiding damage to the material caused by improper height control when the clamping assembly 310 grips the material; as the material moves with the Y-axis moving frame 3212, the Z-axis assembly 322 lifts the material to a suitable height, effectively preventing collisions between the material and the frame 200 or other components, and improving the material yield.

[0038] Please continue to refer to this. Figure 3 The clamping assembly 310 includes multiple suction cups 311.

[0039] The suction cups 311 can be made of a flexible, soft material, such as nitrile rubber or silicone, which provides good sealing to ensure adhesion and also acts as a buffer when in contact with materials to prevent damage to the material surface. The clamping assembly 310 mainly includes four suction cups 311 arranged in a rectangular structure. The carrier 230 holds two sets of materials simultaneously; the four suction cups 311 can simultaneously pick up both sets of materials, improving transfer efficiency.

[0040] Please refer to Figure 2 , Figure 4 as well as Figure 6 The discharge drive module 420 includes two discharge guide rails 421 respectively disposed on both sides of the loading platform 410 parallel to the Y-axis guide rail 3211. The two discharge guide rails 421 are located below the Y-axis guide rail 3211. The end of any discharge guide rail 421 near the feed port 210 extends toward the feed port 210. The frame 200 is provided with discharge sliders 422 on both sides parallel to the discharge guide rails 421. The two discharge guide rails 421 are slidably connected to the two discharge sliders 422 respectively.

[0041] Two discharge guide rails 421 are respectively set on both sides of the loading platform 410 parallel to the Y-axis guide rail 3211, providing stable support for the loading platform 410 and effectively balancing the torque generated by the loading platform 410 during movement, ensuring its stability during movement. Furthermore, the two discharge guide rails 421 are located below the Y-axis guide rail 3211, making full use of the vertical space inside the frame 200. This allows the Y-axis assembly 321 and the discharge drive module 420 to form an upper and lower layer distribution in space, avoiding horizontal spatial conflicts, greatly improving the utilization rate of the internal space of the frame 200, and enhancing the compactness of the mechanism.

[0042] One end of any discharge guide rail 421 near the feed inlet 210 extends towards the feed inlet 210, which can extend the travel of the carrying platform 410 and ensure that the carrying platform 410 can smoothly extend out of the frame 200, making it convenient for the robot arm in the next process to pick up the material. The discharge sliders 422 are respectively arranged on both sides of the frame 200 parallel to the discharge guide rails 421, forming a sliding connection with the two discharge guide rails 421, which can guide the carrying platform 410 to move along a predetermined path, improving the accuracy of material transfer and increasing efficiency.

[0043] After the clamping assembly 310 places the material on the loading platform 410, the discharge drive module 420 starts working. Under the action of the servo motor driving the lead screw, the discharge guide rails 421 on both sides of the loading platform 410 slide along the discharge slider 422 on the frame 200, thereby driving the loading platform 410 to slide. Since the end of the discharge guide rail 421 near the feed port 210 extends towards the feed port 210, and the two discharge guide rails 421 are located below the Y-axis guide rail 3211, the loading platform 410 can move smoothly towards the discharge port 220 along with the discharge guide rails 421. As the discharge guide rails 421 slide, the loading platform 410 gradually extends from inside the frame 200 to the outside until it is completely outside the frame 200. At this time, the loading platform 410 is within the operable range of the robot in the next process, making it convenient for the robot to pick up the material. After the material is removed, the drive unit reverses its operation, causing the discharge guide rail 421 to slide along the discharge slider 422 into the frame 200, so that the loading platform 410 retracts into the frame 200 and returns to its initial position, waiting to receive the next material, thus completing a complete discharge process.

[0044] The sliding cooperation between the discharge guide rail 421 and the discharge slider 422 of this utility model ensures the stability and accuracy of the movement of the loading platform 410, enabling the loading platform 410 to quickly and accurately extend and retract from the discharge port 220, shortening the waiting time of materials in the discharge stage. At the same time, the loading platform 410 smoothly extends beyond the frame 200, facilitating the rapid material retrieval by the robot arm in the next process, reducing the time cost of process connection and improving production efficiency.

[0045] Please refer to Figure 4 and Figure 5 as well as Figure 7 The loading platform 410 is equipped with multiple sets of positioning fixtures 430 for fixing materials and positioning drive components 440 connected to the positioning fixtures 430. The positioning fixtures 430 can be in the form of pins or blocks. Each fixture can be connected to the loading platform 410 by bolts, ensuring that no displacement occurs during material placement and movement, and facilitating future maintenance and replacement.

[0046] As a preferred embodiment of this utility model, please refer to Figure 5 and Figure 7 The positioning fixture 430 adopts a pin structure. The loading platform 410 is provided with multiple clearance holes 411 corresponding to the positioning fixture 430. The positioning fixture 430 includes a clamping part 431 and a fixing part 432. The clamping part 431 protrudes through the clearance holes 411 and protrudes from the surface of the loading platform 410. Multiple positioning drive members 440 are provided at the bottom of the loading platform 410, and the fixing part 432 is connected to the positioning drive members 440.

[0047] This can be understood as follows: the clamping part 431, at least partially, has a pin structure that passes through the clearance hole 411 and protrudes from the surface of the loading platform 410 to fix the material. The fixing part 432 has a rectangular structure, and both ends of the fixing part 432 are connected to a clamping part 431. That is to say, a positioning fixture 430 is provided with two clamping parts 431, which can simultaneously drive the two clamping parts 431 to position the material under the drive of the positioning drive member 440.

[0048] The positioning drive component 440 can be a cylinder, such as a slide cylinder. The slide cylinder is bolted to the bottom of the loading platform 410, which can improve the connection stability between the slide cylinder and the loading platform 410 and facilitate disassembly and replacement. The middle part of the fixing part 432 is connected to the side of the slide cylinder facing away from the loading platform 410. When the slide cylinder is working, it can slide to drive the positioning fixture 430 to move within the clearance hole 411, thereby positioning the material.

[0049] To locate all four sides of a rectangular material, please refer to... Figure 4 The multiple positioning fixtures 430 include a Y-direction positioning fixture 433 disposed in the middle of the loading platform 410, and at least two X-direction positioning fixtures 434 disposed on both sides of the loading platform 410 near the discharge guide rail 421. The Y-direction positioning fixtures 433 are provided in at least four sets.

[0050] The mechanism of this embodiment can transport two pieces of material simultaneously. Four sets of Y-axis positioning fixtures 433 are arranged in the middle of the loading platform 410. That is, each piece of material is positioned in the width direction by two sets of Y-axis positioning fixtures 433. At this time, the length direction of the clearance hole 411 is perpendicular to the long side of the material, and the clamping part 431 can move within the clearance hole 411 under the drive of the slide cylinder to move closer to the sides of the material to achieve positioning.

[0051] X-axis positioning fixtures 434 are respectively disposed on both sides of the loading platform 410. At this time, the length direction of the clearance hole 411 adapted to the X-axis positioning fixture 434 is perpendicular to the wide side of the material. That is to say, the clamping part 431 of the X-axis positioning fixture 434 can move in the clearance hole 411 under the drive of the slide cylinder to get close to the two ends of the material for positioning. Then, it cooperates with the Y-axis positioning fixture 433 to position the four sides of the material, ensuring that the material is fixed stably and accurately on the loading platform 410, avoiding the loading platform 410 from shifting when moving, affecting the subsequent material picking by the robot, and thus improving production efficiency.

[0052] To facilitate timely access to the status of the mechanism and production line conditions for on-site personnel, an alarm system is installed on the top of the frame 200. The alarm system includes a buzzer and a tri-color indicator light. When a malfunction occurs in the mechanism or material handling, the buzzer will sound to alert on-site personnel, while the tri-color indicator light will flash red or yellow. This allows on-site personnel to quickly grasp the situation and respond promptly, preventing prolonged malfunctions from impacting production.

[0053] In some embodiments, the frame 200 is equipped with four wheels at its bottom. These wheels are located at the four corners of the frame 200. The wheels can be made of high-strength polyurethane or rubber, and possess a certain degree of elasticity and wear resistance to adapt to slight unevenness in the workshop floor, reducing vibration during movement.

[0054] On the one hand, when the workshop production line is adjusted, the automatic feeding device 100 for automotive parts painting does not need to rely on large equipment such as forklifts. It can be manually pushed to change the position, which reduces the difficulty and cost of moving the mechanism and makes the entire stamping production system more convenient to adapt to different production needs and site layouts.

[0055] On the other hand, the casters allow for convenient centralized storage or flexible relocation of the mechanism when not in use, preventing it from occupying fixed space for extended periods, which is especially suitable for situations where workshop space is limited. When maintenance is required, the mechanism can be easily moved to a spacious area, providing ample operating space for maintenance personnel.

[0056] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the contents of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
