Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to an error-proofing device for automatic clamping and assembly processes. Background Technology

[0002] As a key piece of equipment for the intelligent upgrading of modern manufacturing, automatic clamping and assembly process error prevention equipment is mainly used to monitor and prevent errors in the clamping and assembly process of workpieces in real time on automated production lines. By integrating multiple technologies such as mechanics, electronics and sensors, this type of equipment can quickly identify problems such as dimensional deviations, incorrect installation orientation and missing parts in the workpiece clamping and component assembly stages, avoiding the generation of defective products due to human negligence or mechanical errors, thereby improving product quality and production efficiency. It has important application value in the high-precision production fields of automobile manufacturing and electronic equipment assembly.

[0003] Early error-proofing devices for automated clamping and assembly processes consisted of simple mechanical limiting structures and basic sensors. Mechanical blocks limited the workpiece position, and photoelectric sensors detected the presence of components. However, this structure could only achieve basic position determination and could not accurately measure the dimensional deviations of the workpiece. Current equipment incorporates vision inspection systems and contact measurement probes. High-definition cameras capture images, and probes contact the workpiece surface, improving detection accuracy to some extent. However, in practical applications, existing error-proofing devices, due to the separate arrangement of vision inspection and contact measurement modules, and the limitations of the robotic arm's movement trajectory and detection angle, can only perform single-point or linear measurements on specific directions and parts of the workpiece during operation. This makes it difficult to cover the entire surface of the workpiece, especially for workpieces with complex curved surfaces and internal structures. Because traditional inspection structures cannot flexibly adjust the inspection posture and position, they cannot accurately determine whether the workpiece meets assembly requirements, affecting the detection efficiency and production quality assurance capabilities of the error-proofing equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic clamping and assembly process error prevention device, which aims to improve the problem in the prior art that the detection structure cannot flexibly adjust the detection posture and position, thus making it impossible to accurately determine whether the workpiece meets the assembly requirements.

A sliding rod is slidably connected to the bottom of the sliding block. Multiple rotating rings are rotatably connected to the bottom of the outer wall of the sliding rod. Multiple return springs are fixedly connected to the outer wall of the rotating rings. A contact ring is fixedly connected to the other end of each of the multiple return springs. A multi-functional identification mechanism is provided on the left side of the outer wall of the T-shaped slide rail. The multi-functional identification mechanism is used to collect data and install equipment in multiple ways.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an automatic clamping and assembly process error-proofing device, including a workbench 1. Supports 3 are fixedly connected to the top left and right sides of the workbench 1. A T-shaped slide rail 4 is fixedly connected to the middle of an adjacent side of the two supports 3. A T-shaped moving block 5 is slidably connected to the bottom of the outer wall of the T-shaped slide rail 4. A servo motor 6 is fixedly connected to the top of the T-shaped moving block 5. The output end of the servo motor 6 passes through the T-shaped moving block 5 and is fixedly connected to a pulley 7. The inner wall of the pulley 7 engages with the outer wall of the T-shaped slide rail 4. Activating the servo motor 6 causes the pulley 7 to roll on the T-shaped slide rail 4, allowing the T-shaped moving block 5 to slide smoothly left and right along the T-shaped slide rail 4. A rotary motor 8 is fixedly connected to the bottom of the inner wall of the T-shaped moving block 5. The output end of the rotary motor 8 passes through the T-shaped moving block 5 and is fixedly connected to a semi-hollow plate 9. Activating the rotary motor 8 drives the semi-hollow plate 9 to rotate, changing the detection angle of the detection component below. An electric telescopic rod 10 is fixedly connected to the bottom of the core plate 9. A sliding block 11 is fixedly connected to one end of the electric telescopic rod 10. When making small adjustments, the electric telescopic rod 10 can be activated to drive the sliding block 11 and the structure above it to make slight adjustments. A sliding rod 12 is slidably connected to the bottom of the sliding block 11. Multiple rotating rings 13 are rotatably connected to the bottom of the outer wall of the sliding rod 12. Multiple return springs 14 are fixedly connected to the outer wall of the rotating rings 13. A contact ring 15 is fixedly connected to the other end of each of the multiple return springs 14. The return springs 14 provide buffering force for the contact rings 15 to ensure that the contact rings 15 can fit tightly against the surface of the workpiece and accurately transmit pressure signals during contact detection, so that the contact rings 15 fit against the surface of the workpiece. Then, contact detection is performed around the workpiece as required. A multi-functional identification mechanism 2 is provided on the left side of the outer wall of the T-shaped slide rail 4. The multi-functional identification mechanism 2 is used to collect data in multiple ways and for the installation of equipment.

[0033] Specifically, when workpiece inspection is required, the servo motor 6 can be activated, causing the pulley 7 to roll on the T-shaped slide rail 4. This allows the T-shaped moving block 5 to slide smoothly left and right along the T-shaped slide rail 4, thereby adjusting the lateral position of all components mounted on it. Simultaneously, the rotary motor 8 is activated, driving the semi-hollow plate 9 to rotate, changing the inspection angle of the inspection components below. When the workpiece position to be inspected is reached, if the workpiece requires only a small adjustment, the electric telescopic rod 10 can be activated, causing the sliding block 11 and the upper structure to make slight adjustments. For large-scale adjustments, the required adjustment angle can be achieved by rotating the semi-hollow plate 9. This adjustment allows the contact ring 15 to fit against the surface of the workpiece. Subsequently, contact detection is performed around the workpiece as needed. When the workpiece exceeds the error range, it will squeeze the contact ring 15, and the return spring 14 above it will contract or stretch accordingly. The return spring 14 provides a buffering force for the contact ring 15, ensuring that the contact ring 15 can fit tightly against the workpiece surface. This allows for accurate transmission of pressure signals during contact detection, thereby flexibly adjusting the detection posture and position to ensure the accuracy of the detection results.

[0034] Reference Figure 3 , Figure 4 and Figure 6 The multi-functional identification mechanism 2 includes a 3D scanning device 201. The inner wall of the 3D scanning device 201 is slidably connected to the middle of the bottom side of the outer wall of the T-shaped slide rail 4. The 3D scanning device 201 performs omnidirectional 3D data scanning and acquisition of the workpiece. A slot block 202 is fixedly connected to the left side of the 3D scanning device 201. A lead screw 204 is fixedly connected to the middle of the right side of the inner wall of the slot block 202. A pressing disc 203 is threadedly connected to the outer wall of the lead screw 204. A high-definition camera 205 is set on the left side of the 3D scanning device 201. The high-definition camera 205 captures high-definition images of the surface details of the workpiece. The right side of the high-definition camera 205 is fixedly connected to the slot block 202. A T-shaped locking block 206 is fixedly connected to the camera. The T-shaped locking block 206 can lock the high-definition camera 205 into the slot block 202. Then, by rotating the pressing disc 203, it moves above the lead screw 204 and presses it above the T-shaped locking block 206 to prevent it from falling and being damaged due to vibration during use. The outer wall of the T-shaped locking block 206 is engaged with the inner wall of the slot block 202. The top front and rear sides of the T-shaped moving block 5 are rotatably connected with grooved locking plates 207. The top front and rear sides of the 3D scanning device 201 are fixedly connected with limit posts 208. The inner wall of the grooved locking plate 207 is engaged with the outer wall of the corresponding limit post 208.

[0035] Specifically, by utilizing the rotation of the grooved clamping plate 207 and engaging with the limiting post 208, the 3D scanning device 201 is connected to the T-shaped moving block 5. This allows the 3D scanning device 201 and the structure above it to move together via the movement of the T-shaped moving block 5. The 3D scanning device 201 performs comprehensive 3D data scanning and acquisition of the workpiece, and the high-definition camera 205 captures high-definition images of the workpiece surface details to supplement the visual information of the 3D scan. The high-definition camera 205 can be engaged in the slot block 202 via the T-shaped clamping block 206. Then, by rotating the pressing disc 203, it moves above the lead screw 204 and presses against the T-shaped clamping block 206, preventing it from falling and being damaged due to vibration during use. This allows for multi-dimensional data acquisition and analysis of the workpiece, achieving precise error prevention during the automatic clamping and assembly process.

[0036] Reference Figure 1 and Figure 5 A hollow plate 29 is fixedly connected to the middle of the outer wall of the sliding rod 12. Infrared ray sensors 26 are slidably connected to the front and rear sides of the inner wall of the hollow plate 29. A fixing bolt 28 is threadedly connected to the right side of the infrared ray sensor 26. A limit strip 27 is fixedly connected to the left side of the inner wall of the hollow plate 29. The front and rear sides of the outer wall of the limit strip 27 are slidably connected to the inner wall of the corresponding infrared ray sensor 26. An adjusting nut 16 is rotatably connected to the top of the sliding block 11. A threaded post 17 is fixedly connected to the top of the sliding block 11 through the sliding block 11. The outer wall of the threaded post 17 is threadedly connected to the inner wall of the adjusting nut 16.

[0037] Specifically, the hollow plate 29 provides an installation carrier and working space for the subsequent infrared ray sensor 26. The infrared ray sensor 26 can be flexibly adjusted in the horizontal direction according to actual detection needs to adapt to detection scenarios of workpieces of different sizes and shapes, achieving more comprehensive and accurate detection coverage of the workpieces. The fixing bolts 28 can firmly fix the infrared ray sensor 26 to the hollow plate 29 after it is adjusted to a suitable position, preventing the sensor from being displaced due to vibration or external force during equipment operation, thereby ensuring the accuracy and stability of the detection data. The limiting strip 27 can constrain the sliding range of the infrared ray sensor 26 to prevent it from deviating from the predetermined track during sliding, and at the same time provide guidance for its sliding to ensure that it remains stable during sliding. The position of the threaded post 17 can be changed by adjusting the nut 16, thereby adjusting the height of the sliding rod 12.

[0038] Reference Figure 1 , Figure 2 and Figure 3A column 18 is fixedly connected to the top rear side of the workbench 1, providing a stable mounting base for the warning light 19. The warning light 19 is fixedly connected to the top of the column 18, and can promptly emit a clear light signal or flashing signal when abnormal operation of the equipment occurs. Fume hood doors 20 are rotatably connected to the left and right sides of the front of the inner wall of the workbench 1. The fume hood doors 20 facilitate the operator's operation, maintenance, and storage of items inside the workbench 1. A handle 21 is fixedly connected to the front of the fume hood door 20, providing leverage for the operator to open and close the fume hood door 20. Point; A limiting block 22 is fixedly connected to the top center of the workbench 1. The limiting block 22 can limit the position of the workpiece placed on the workbench 1. Conical support legs 23 are fixedly connected to the four corners of the bottom of the workbench 1. The conical support legs 23 can increase the contact area between the workbench 1 and the ground and improve the stability of the equipment. A fixed column 24 is fixedly connected to the front center of the left side bracket 3. The fixed column 24 can provide a fixed installation position for the display screen 25. The display screen 25 is rotatably connected to the front end of the fixed column 24. The display screen 25 can facilitate the operator to view the equipment operating parameters and test results information in real time.

[0039] Specifically, the column 18 provides a stable mounting base for the warning light 19, allowing it to be perpendicular to the workbench 1 and ensuring good visibility of the warning signal in all directions. The warning light 19 can promptly emit a clear light or flashing signal when abnormal equipment operation occurs, quickly attracting the operator's attention so they can take immediate action to prevent the problem from escalating and ensure production safety and product quality. The fume hood door 20 allows operators to easily operate, maintain, and store items inside the workbench 1. The handle 21 provides a point of leverage for opening and closing the fume hood door 20. The limit block 22 can position the workpiece placed on the workbench 1, ensuring it is in the predetermined processing position. The tapered support leg 23 increases the contact area between the workbench 1 and the ground, improving equipment stability and preventing it from shaking or tipping over during operation. The fixing column 24 provides a fixed mounting position for the display screen 25 and ensures its stability during operation. The display screen 25 allows operators to easily view equipment operating parameters and test results in real time, enabling them to promptly grasp the equipment's working status.

[0040] Working principle: First, when inspecting a workpiece, the servo motor 6 is activated to drive the pulley 7 to roll on the T-shaped slide rail 4, thereby enabling the T-shaped moving block 5 to slide smoothly left and right along the T-shaped slide rail 4. This allows all components mounted on it to adjust their lateral positions. Simultaneously, the rotary motor 8 is activated to rotate the semi-hollow plate 9, changing the detection angle of the detection components below. When the desired workpiece position is reached, if the workpiece requires a small adjustment, the electric telescopic rod 10 can be activated to fine-tune the sliding block 11 and the upper structure. If a large adjustment is required, the semi-hollow plate 9 is rotated to achieve the desired adjustment angle. This adjustment ensures that the contact ring 15 is in close contact with the workpiece surface. Subsequently, contact inspection is performed around the workpiece as needed. When the workpiece exceeds the error range, the contact ring 15 is compressed, and the return spring 14 contracts or stretches accordingly, providing a buffer force for the contact ring 15 to ensure it is in close contact with the workpiece surface. During the contact inspection process, the return spring 14 accurately transmits pressure signals and flexibly adjusts the inspection posture and position to ensure the accuracy of the inspection results.

[0041] Furthermore, through the multi-functional identification mechanism 2, the rotation of the grooved plate 207 and the cooperation of the limiting post 208 are used to connect the 3D scanning device 201 and the T-shaped moving block 5. This allows the 3D scanning device 201 to move synchronously with the structure above it by means of the displacement of the T-shaped moving block 5. The 3D scanning device 201 performs comprehensive 3D data scanning and acquisition on the workpiece, while the high-definition camera 205 is responsible for capturing detailed images of the workpiece surface to supplement the visual information of the 3D scan. The T-shaped plate 206 is engaged in the slot block 202 to ensure the stable fixation of the high-definition camera 205. By rotating the pressing disc 203, it moves on the lead screw 204 and applies pressure to the T-shaped plate 206 to prevent it from falling off and being damaged due to vibration during use. This ensures multi-angle data acquisition and analysis of the workpiece, thereby achieving precise error prevention during the automatic clamping and assembly process.
