They are mostly made of steel, such as carbon steel and low-alloy steel. A connecting rod consists of three parts: the small end, the rod body, and the big end. The rod body has recessed weight-reducing grooves. During the production of connecting rods, visual inspection of their dimensions and appearance is required. Existing connection inspection equipment mostly relies on manual hand-held visual inspection of the connecting rod, especially when inspecting the edges and sidewalls. The operator's hands can easily obstruct the inspection area, requiring multiple adjustments to the connecting rod's position and affecting inspection efficiency. Utility Model Content

Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0018] refer to Figures 1 to 9A linkage inspection device is characterized by comprising a frame 1, a material transfer mechanism 11 mounted on the frame 1, a multi-axis robotic arm 4, a first inspection mechanism 2, a second inspection mechanism 3, a third inspection mechanism 6, a horizontal conveyor, two oppositely arranged placement platforms 7, a material transfer mechanism 8, a good product discharge channel 9, and a waste product discharge channel 10, both of which are inclined and have upward openings. The operating end of the multi-axis robotic arm 4 is equipped with a positioning and clamping mechanism 41 for clamping the linkage workpiece 14. The working surface of the horizontal conveyor 5 is equipped with a clamping and flipping mechanism 51 for clamping the linkage workpiece 14 and driving it to rotate.

[0019] A protective cover 12 is also provided on the frame 1. The protective cover 12 has through holes 1201 at the positions of the good product discharge channel 9, the waste product discharge channel 10, and the material transfer mechanism 11. A controller 13 is provided on the protective cover 12. The multi-axis robot arm 4, the positioning and clamping mechanism 41, the first detection mechanism 2, the second detection mechanism 3, the third detection mechanism 6, the horizontal conveyor 5, the clamping and flipping mechanism 51, and the material transfer mechanism 8 are all connected to and controlled by the controller 13. A material receiving platform 1101 is provided on the translation end of the material transfer mechanism 11. The material receiving platform 1101 is driven by an electric lead screw to translate the material receiving platform 1101 so that it moves through the corresponding through holes 1201 to the outside of the protective cover 12 so that the operator can place the connecting rod workpiece 14 horizontally on the material receiving platform 1101.

[0020] The positioning and clamping mechanism 41 includes a clamping mounting plate 411 and clamping members 412 and suction members 413 respectively disposed on both sides of the clamping mounting plate 411. The clamping member 412 is a three-jaw clamping head, which is prior art and will not be described in detail here. The suction member 413 is an electromagnet, which is prior art and will not be described in detail here. An alignment rod 401 is provided between the clamping mounting plate 411 and the clamping member 412 and the suction member 413. Both the clamping member 412 and the suction member 413 are electrically connected to and controlled by the controller 13.

[0021] This connecting rod testing equipment is used to test connecting rod workpiece 14 made of steel, such as carbon steel and alloy steel. The connecting rod workpiece 14 consists of three parts: connecting rod small end 141, rod body 142, and connecting rod big end 143. A recessed weight-reducing groove 1401 is formed on the rod body 142.

[0022] Under the control of the controller 13, the material transfer mechanism 11 drives the material receiving table 1101 to move to a position close to the multi-axis robotic arm 4. The positioning and clamping mechanism 41 of the multi-axis robotic arm clamps the connecting rod workpiece 14. The positioning and clamping mechanism 41 positions the connecting rod big end 143 and connecting rod small end 141 of the connecting rod workpiece 14 respectively through the clamping member 412 and the adsorption member 413 on the clamping mounting plate 411. The three clamping fingers of the clamping member 412 extend into the through area of ​​the ring-shaped connecting rod big end 143. The clamping member 412 clamps the connecting rod big end 143 of the connecting rod workpiece 14. The adsorption member 413 abuts against the connecting rod small end 141. Using the magnetic attraction of the electromagnet to the metal, the adsorption member 413 adsorbs the connecting rod small end 141 of the connecting rod workpiece 14. The alignment rod 401 and the weight reduction groove 1401 of the rod body 142 are in a concave-convex fit, which guides the positioning clamping mechanism 41 to align with the connecting rod workpiece 14 in the correct position and plays a limiting role for the connecting rod workpiece 14.

[0023] A multi-axis robotic arm drives the connecting rod workpiece 14 through a positioning and clamping mechanism 41, causing it to pass sequentially through a first inspection mechanism 2 and a second inspection mechanism 3. Both the first inspection mechanism 2 and the second inspection mechanism 3 include a first inspection frame 101 and two first visual inspection devices 102. The two first visual inspection devices 102 are arranged vertically spaced and opposite to each other on the first inspection frame 101. The first visual inspection devices 102 are electrically connected to and controlled by a controller 13. The first visual inspection devices 102 can be CCD cameras. Two first lighting devices 103, also arranged vertically spaced and opposite to each other, are also provided on the first inspection frame 101 to provide a bright environment and ensure better visual inspection results. The first inspection mechanism 2 is used to perform visual inspection on the sidewall of the rod body 142, and the second inspection mechanism 3 is used to perform visual inspection on the sidewall of the big end 143 and the sidewall of the small end 141 of the connecting rod, respectively. In this process, the design of the positioning and clamping mechanism 41 ensures stable clamping of the connecting rod workpiece 14 while also preventing the sidewall of the connecting rod workpiece 14 from being obscured by the clamping part. This allows the first inspection mechanism 2 and the second inspection mechanism 3 to perform a more comprehensive visual inspection on the sidewall of the connecting rod workpiece 14. The inspection range includes the sidewall of the rod body 142, the sidewall of the big end 143 of the connecting rod, and the sidewall of the small end 141 of the connecting rod. This avoids the inconvenience and inefficiency caused by the need to adjust the position of the connecting rod workpiece 14 multiple times during manual operation, thereby completing the visual inspection of the connecting rod workpiece 14 efficiently and accurately.

[0024] Two placement platforms 7 are located on either side of the horizontal conveyor 5. One placement platform 7 is close to the transfer mechanism 8, and the other placement platform 7 is close to the second inspection mechanism 3. Each placement platform 7 is equipped with a feeding plate 701 located between two clamping docking parts 5122, for placing the connecting rod workpiece 14. The third inspection mechanism 6 is located close to the horizontal conveyor 5. The horizontal conveyor 5 can be any linear drive device such as an electric push rod, a linear conveyor belt, or a telescopic cylinder. The third inspection mechanism 6 includes a second inspection frame 61, an inspection lifting mechanism 62 mounted on the second inspection frame 61, and a second visual inspection device 63 mounted on the lifting end of the inspection lifting mechanism 62. The second visual inspection device 63 is electrically connected to and controlled by the controller 13. The second visual inspection device 63 can be a CCD camera. A second lighting device 601 is mounted on the second inspection frame 61.

[0025] The clamping and flipping mechanism 51 includes a travel mounting plate 511 and two flipping clamping assemblies 512 arranged opposite to and spaced apart on both sides of the travel mounting plate 511. The flipping clamping assembly 512 includes a movable frame 5121, a clamping docking piece 5122 and a clamping rotation mechanism 5123. The movable frame 5121 is slidably mounted on the travel mounting plate 511. Both sides of the travel mounting plate 511 are provided with clearance grooves 502 for the movable frame 5121 to pass through. The clamping docking member 5122 is pivotally connected to the upper part of the movable frame 5121, and the clamping rotation mechanism 5123 is located at the lower part of the movable frame 5121. The rotating end of the clamping rotation mechanism 5123 is connected to the clamping docking member 5122 by a synchronous belt drive. The clamping rotation mechanism 5123 is a rotary motor and is connected to and controlled by the controller 13. Both the rotating end of the clamping rotation mechanism 5123 and the pivot of the clamping docking member 5122 are provided with synchronous belt pulleys for the synchronous belt to engage, so that the clamping rotation mechanism 5123 drives the clamping docking member 5122 to rotate. The stroke mounting plate 511 is provided with two oppositely arranged telescopic mechanisms 501. The telescopic mechanism 501 is a telescopic cylinder and is connected to and controlled by the controller 13. The telescopic ends of the two telescopic mechanisms 501 are respectively connected to the two movable frames 5121.

[0026] After the connecting rod workpiece 14 undergoes visual inspection of its edge sidewalls by the first visual inspection mechanism and the second inspection mechanism 3, the multi-axis robotic arm uses the positioning and clamping mechanism 41 to move the connecting rod workpiece 14 horizontally onto the feeding plate 701 of the placement platform 7 near the second inspection mechanism 3. The horizontal conveyor 5 drives the clamping and flipping mechanism 51 to translate, so that the two flipping clamping components 512 move to the placement platform 7. The two clamping docking parts 5122 correspond to the large end 143 and the small end 141 of the connecting rod, respectively. Under the control of the controller 13, the two clamping rotation mechanisms 5123 drive the two clamping docking parts 5122 to rotate, so that the two clamping docking parts 5122 are adapted to the large end 143 and the small end 141 of the connecting rod, respectively. The two telescopic mechanisms 501 drive the two movable frames 5121 to translate, so that the two clamping docking parts 5122 are adapted to the large end 143 and the small end 141 of the connecting rod, respectively. The clamping and flipping mechanism 51 clamps the connecting rod workpiece 14 by pressing against the large end 143 and the small end 141 of the connecting rod respectively. Then, the horizontal conveyor 5 drives the clamping and flipping mechanism 51 to translate so that the two flipping clamping components 512 move to the first vision inspection mechanism. The two clamping rotation mechanisms 5123 of the clamping and flipping mechanism 51 drive the two clamping docking parts 5122 to rotate synchronously so that the clamped connecting rod workpiece 14 is rotated so that the second vision inspection device 63 can perform a more comprehensive vision inspection of the connecting rod workpiece 14 at different angle positions. After the inspection is completed, the horizontal conveyor 5 drives the clamping and flipping mechanism 51 to translate so that the two flipping clamping components 512 move to the placement platform 7 near the transfer mechanism 8. The two telescopic mechanisms 501 drive the two movable frames 5121 to separate from each other so that the connecting rod workpiece 14 is placed on the corresponding release plate 701.

[0027] The material transfer mechanism 8 includes a material transfer mounting frame 81, a material transfer translation mechanism 82, a material transfer lifting mechanism 83, and a material transfer clamping mechanism 84. The material transfer mounting frame 81 is a gantry frame. The material transfer translation mechanism 82 is mounted on the crossbeam of the material transfer mounting frame 81 and is an electric slide table. The material transfer translation mechanism 82 is electrically connected to and controlled by the controller 13. The material transfer clamping mechanism 84 has the same structure as the positioning clamping mechanism 41 and is electrically connected to and controlled by the controller 13. The material transfer mechanism 8 adjusts the position of the material transfer clamping mechanism 84 through the material transfer translation mechanism 82 and the material transfer lifting mechanism 83. The material transfer clamping mechanism 84 picks up the connecting rod workpiece 14 from the feeding plate 701. Based on the detection result of the connecting rod workpiece 14, the material transfer clamping mechanism 84 moves to the top of the good product discharge channel 9 or the waste product discharge channel 10 to discharge the workpiece, thereby realizing the classified discharge of the connecting rod workpiece 14.

[0028] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
