[0002] The automated feeding device for automobile production is equipped with a servo drive unit, a vision sensing system, and a programmable control system. The vision system identifies the position and posture of automobile parts, the control system plans the motion trajectory, and the actuators are driven in coordination through various joints. It adopts a rigid linkage and precision transmission structure.

[0003] Current technology can automatically grab, precisely transport, and load materials such as stamped parts and hardware into designated workstations, adapting to the flexible loading needs of parts for multiple vehicle models. It can reduce manual intervention, improve loading efficiency and positional accuracy, reduce the risk of part damage, and adapt to continuous and intelligent operation scenarios on automotive production lines.

[0004] While existing automated feeding devices for automobile production achieve flexible feeding requirements for parts across multiple vehicle models, reducing manual intervention, improving feeding efficiency and positional accuracy, and lowering the risk of part damage, thus adapting to the continuous and intelligent operation scenarios of automobile production lines, they face many prominent problems in practical use. In terms of specific operation, for materials with particularly complex shapes, significant size variations, or special materials, difficulties in grasping and smooth conveying may still exist. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative automated feeding device for automobile production to solve these problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides an automatic feeding device for automobile production, which solves the problems that may still exist for materials with particularly complex shapes, large size differences, or special materials, such as difficulty in grasping and poor conveying.

[0006] The device includes a robotic arm assembly, which includes a robotic arm wrist. A gripping assembly is located below the robotic arm wrist. The gripping assembly includes a mounting plate. A motor is fixedly connected to the center of the lower surface of the mounting plate. A gear is fixedly connected to the output end of the motor. Square connecting plates are fixedly connected to both sides of the mounting plate. Two mounting strips are fixedly connected to the bottom of the two square connecting plates. The mounting strips are of two types and are positioned correspondingly. A gripping post is fixedly connected to the lower surface of the outer mounting strip. Square sliding holes are opened on the side surfaces of the two mounting strips. A rack is slidably connected to the inner wall of the square sliding hole. The gripping post is fixedly connected to the lower surface of the inner end of the rack. The rack meshes with the side surface of the gear. The upper surface of the mounting plate is fixedly connected to the bottom of the robotic arm wrist.

[0007] Each of the two clamping columns has a hanging block fixedly connected to one side surface, and a square limiting plate is fixedly connected to the outer end surface of the rack.

[0008] The upper surface of the hanging block is provided with an anti-slip pad, and the space between the rack and the square sliding hole is coated with lubricating oil.

[0009] The outer surface of the motor is fixedly connected to the inner wall of the square connecting plate, and the gap between the square connecting plate and the motor is filled with shock-absorbing pads.

[0012] The mounting base has four mounting holes on its upper surface, which are evenly distributed at the four corners of the upper surface of the mounting base.

[0013] 1. In this utility model, the gear fixedly connected to the motor output end precisely meshes with the racks on both sides for transmission. Combined with the limiting and guiding effect of the square sliding hole on the racks, the two clamping columns move synchronously and smoothly in opposite directions along a fixed trajectory, avoiding the problems of displacement, shaking or uneven force on automotive parts during the clamping process. This achieves stable and precise clamping of automotive stamping parts and hardware parts of different specifications, ensuring the stability of the parts' posture during the loading process.

[0014] 2. In this utility model, the anti-slip pads on the upper surface of the hanging block increase the friction of the clamping surface, the shock-absorbing pads filled between the motor and the square connecting plate buffer the running vibration, and the lubricating oil applied between the rack and the square sliding hole optimizes the transmission effect. This makes it difficult for parts to slip during clamping, the equipment operates with low noise, and the transmission is smooth and without jamming. It avoids scratches and deformation on the surface of the parts and excessive wear on the transmission components of the equipment, thus achieving efficient, low-consumption, and safe automatic feeding of automotive parts.

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1-5An automatic feeding device for automobile production includes a robotic arm assembly 1, which includes a robotic arm wrist 104. A clamping assembly 2 is disposed below the robotic arm wrist 104. The clamping assembly 2 includes a mounting plate 201. A motor 203 is fixedly connected to the center of the lower surface of the mounting plate 201. A gear 204 is fixedly connected to the output end of the motor 203. Square connecting plates 202 are fixedly connected to both sides of the mounting plate 201. Two mounting strips 205 are fixedly connected to the bottom of the two square connecting plates 202. There are two mounting strips 205, and their positions are corresponding. A clamping post 210 is fixedly connected to the lower surface of the outer mounting strip 205. Square sliding holes 206 are opened on the side surfaces of the two mounting strips 205. A rack 207 is slidably connected to the inner wall of the square sliding hole 206. The clamping post 210 is fixedly connected to the lower surface of the inner end of the rack 207. The rack 207 meshes with the side surface of the gear 204. The upper surface of the mounting plate 201 is fixedly connected to the bottom of the robotic arm wrist 104. Each of the two clamping posts 210 has a hanging block 208 fixedly connected to one side surface, and a square limiting plate 209 fixedly connected to the outer end surface of the rack 207. An anti-slip pad is provided on the upper surface of the hanging block 208, and lubricating oil is applied between the rack 207 and the square sliding hole 206. The outer surface of the motor 203 is fixedly connected to the inner wall of the square connecting plate 202, and shock-absorbing pads are filled in the gap between the square connecting plate 202 and the motor 203. When the device is started, the output end of the motor 203, which is fixed at the center of the lower surface of the mounting plate 201, drives the gear 204 to rotate. Since the gear 204 meshes with the racks 207 on both sides, and the racks 207 are limited and guided by the square sliding holes 206 opened on the side surface of the mounting strip 205, the racks 207 on both sides are forced to slide smoothly in opposite directions along the inner wall of the square sliding holes 206. The clamping column 210 fixed on the lower surface of the inner end of the rack 207 and the hanging block 208 on the corresponding side surface of the clamping column 210 move synchronously with the rack 207, realizing the action of clamping the automotive parts in opposite directions or releasing them in opposite directions. Meanwhile, the anti-slip pad on the upper surface of the hanging block 208 increases the coefficient of friction with the parts, preventing slippage during clamping; the lubricating oil between the rack 207 and the square sliding hole 206 reduces sliding friction resistance and transmission loss; the shock-absorbing pad filling the gap between the outer side of the motor 203 and the inner wall of the square connecting plate 202 buffers the vibration of the motor 203 during operation, and the square limiting plate 209 at the outer end of the rack 207 prevents the rack 207 from disengaging from the square sliding hole 206, thus ensuring the accuracy and stability of the clamping action as a whole.

[0024] Please see Figures 1-5Based on the first embodiment, a forearm 103 is hinged to the top of the robotic arm wrist 104, and a large arm 102 is hinged to the left end of the forearm 103. A mounting base 101 is fixedly connected to the bottom of the large arm 102, and an anti-slip pad is provided on the lower surface of the mounting base 101. Four mounting holes 105 are provided on the upper surface of the mounting base 101, and the holes 105 are evenly distributed at the four corners of the upper surface of the mounting base 101. The robotic arm assembly 1 is fixed to the mounting base 101 at the bottom of the robotic arm upper arm 102. The mounting base 101 is fastened to the working surface through mounting holes 105 evenly distributed at the four corners of the upper surface, and the anti-slip pad on the lower surface enhances the overall placement stability. The left end of the robotic arm forearm 103 is hinged to the robotic arm upper arm 102, and can swing around the hinge axis to adjust the working radius. The top of the robotic arm wrist 104 is hinged to the robotic arm forearm 103, and the end posture can be flexibly adjusted. The upper surface of the mounting plate 201 is fixed to the bottom of the robotic arm wrist 104, so that the gripping assembly 2 can complete the gripping, handling and loading of automotive parts and designated workstations in three-dimensional space with the coordinated movement of the robotic arm wrist 104, robotic arm forearm 103 and robotic arm upper arm 102, adapting to the multi-position operation requirements of the production line.

[0025] Working principle: When this automatic feeding device for automobile production is in operation, the device is first installed and fixed: the mounting base 101 is fixedly connected to the bottom of the robotic arm assembly 1 via the robotic arm 102. The four mounting holes 105 evenly distributed at the four corners of the upper surface of the mounting base 101 are used in conjunction with bolts and other fasteners to firmly assemble the entire device onto the designated working surface in the automobile production workshop. The anti-slip pads on the lower surface of the mounting base 101 are closely attached to the working surface, effectively increasing the contact friction and preventing the device from shifting or shaking due to vibration during operation, thus providing a stable and reliable support benchmark for subsequent feeding operations. After the device is fixed, the robotic arm assembly 1 is activated and its position is adjusted: the upper arm 102, as the core support component, provides the foundation for the movement of the entire robotic arm; the left end of the lower arm 103 is hinged to the top of the upper arm 102, allowing for a wide range of pitch swing around the hinge axis, thereby adjusting the working radius of the robotic arm to adapt to different material loading requirements; the top of the wrist 104 is hinged to the right end of the lower arm 103, providing flexible posture adjustment capabilities, and can precisely adjust the end-effector direction according to the position and angle of the parts to be gripped. After the control system issues the command, the upper arm 102, lower arm 103, and wrist 104 move in tandem, driving the gripping assembly 2, which is fixedly connected to the bottom of the wrist 104, to move smoothly to the corresponding position directly above the stamped parts and hardware parts to be gripped in automobile production, completing the positioning preparation before gripping. Subsequently, the gripping assembly 2 is activated and performs the part gripping action: the upper surface of the mounting plate 201 of the gripping assembly 2 is fixedly connected to the bottom of the wrist 104 of the robotic arm, providing a mounting carrier for the entire gripping structure. The square connecting plates 202 fixedly connected to both sides of the mounting plate 201 not only serve as connecting supports, but their inner walls are also fixedly connected to the outer surface of the motor 203. The gap between the square connecting plate 202 and the motor 203 is filled with shock-absorbing pads, which can effectively absorb the vibration generated by the motor 203 during operation, prevent the vibration from being transmitted to the gripping components and affecting the gripping accuracy, and reduce the operating noise of the equipment. When the motor 203 receives the gripping command, its output end drives the fixedly connected gear 204 to start rotating. Since the gear 204 meshes with the racks 207 on both sides, and the racks 207 are slidably connected to the inner walls of the square sliding holes 206 opened on the side surfaces of the two mounting strips 205, the square sliding holes 206 form a precise limiting guide for the racks 207, forcing the racks 207 on both sides to slide smoothly in opposite directions along the inner walls of the square sliding holes 206. The clamping post 210, which is fixedly connected to the lower surface of the inner end of the rack 207, moves synchronously with the rack 207. The hanging block 208, which is fixedly connected to the corresponding side surface of the two clamping posts 210, also moves towards each other and gradually approaches the part to be gripped. When the anti-slip pad on the upper surface of the hanging block 208 contacts the surface of the part, it can significantly increase the friction coefficient of the contact surface, prevent the part from slipping or shifting during the clamping process, and ensure the stability of the clamping.Meanwhile, the lubricating oil applied between the rack 207 and the square sliding hole 206 effectively reduces the sliding friction resistance between them, reduces energy loss during transmission, and makes the rack 207 slide more smoothly, avoiding jamming problems that affect work efficiency. The square limiting plate 209 fixedly connected to the outer end surface of the rack 207 can limit the sliding stroke of the rack 207, preventing it from disengaging from the square sliding hole 206 during movement, ensuring the safety and reliability of the transmission structure. After the parts are firmly clamped, the robotic arm assembly 1 starts coordinated movement again: the robotic arm upper arm 102, robotic arm lower arm 103 and robotic arm wrist 104 precisely drive the clamping assembly 2 and the clamped parts to move smoothly in three-dimensional space according to the preset motion trajectory and the path planned by the control system, avoiding other equipment and obstacles on the production line, and accurately arriving at the designated loading station of the automobile production line. Upon reaching the target position, motor 203 receives a reverse drive command, and its output drives gear 204 to rotate in the opposite direction. This, in turn, drives the racks 207 on both sides to synchronously and in the opposite direction along the inner wall of the square sliding hole 206. The clamping column 210 and the hanging block 208 move in opposite directions, gradually releasing the clamp on the parts and allowing them to be stably placed on the designated assembly position or conveying mechanism, completing a full automatic loading operation. The entire workflow requires no manual intervention. Through the coordinated operation of various components, the entire process of picking, handling, and loading automotive parts is fully automated, effectively improving the operational efficiency and loading accuracy of automobile production.
