Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a sorting and conveying device for an automotive metal parts processing production line. Background Technology

[0002] In automobile manufacturing production lines, metal parts often need to be sorted and categorized after processing to facilitate their entry into subsequent assembly or packaging stages. Because stamped or die-cast metal parts are typically heavy and have surface rigidity, they are prone to becoming disordered on conveyor belts. Traditional single-belt conveyors, lacking effective mechanical buffering and physical flow guidance mechanisms, are prone to causing large quantities of heavy metal parts to squeeze and jam at diversion points. This not only reduces the continuity of the production line but also increases downtime and maintenance costs caused by mechanical blockages.

[0003] Chinese patent publication number CN103808734B discloses an invention patent entitled "Fully Automated Inspection Equipment for Automotive Parts." This patent discloses a conveyor device for sorting defective automotive parts. Its main structure includes an inspection table and a mechanical feeding mechanism controlled by a linear module. During operation, a conveyor belt transports metal parts to the workstation. Subsequently, an electrical control unit controls a robotic arm located on the linear module to perform feeding actions, using the robotic arm to screen and discharge specific categories of automotive parts from the main conveyor line.

[0004] The aforementioned device exhibits significant mechanical structural defects when handling high-intensity sorting of large quantities of automotive metal parts: Firstly, the use of a cantilevered robotic arm to grasp and discharge materials one by one results in a long mechanical travel and a relatively weak stress structure. When subjected to continuous rigid impacts from heavy metal parts, it is prone to fatigue wear of the module guide rails. Secondly, the device lacks a physical quantitative sorting and separation mechanism for incoming materials at the front end of the production line. When metal parts arrive in dense clusters, the robotic arm cannot effectively separate overlapping or locked heavy parts, which can easily lead to physical jamming and poor reliability and continuity of equipment operation. Summary of the Invention

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a sorting and conveying device for automotive metal parts processing lines, aiming to solve the problems of easy accumulation and jamming of metal parts during the conveying process, low efficiency of manual sorting, and poor impact resistance of the mechanical structure of the equipment.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A sorting and conveying device for an automotive metal parts processing production line includes: a belt conveyor, a screening mechanism disposed above the feed end of the belt conveyor, a plurality of grouping mechanisms disposed sequentially on the side of the belt conveyor along the conveying direction of the belt conveyor, and a plurality of sorting mechanisms respectively connected to the plurality of grouping mechanisms. The screening mechanism is used to perform preliminary physical screening of automotive metal parts and quantitatively guide them to the belt conveyor. The material distribution mechanism is used to intercept metal parts on the belt conveyor and physically guide them to the corresponding sorting mechanism; The sorting mechanism is used to perform visual inspection and verification on the received metal parts, and trigger pneumatic actuators to sort and discharge them according to the inspection results.

[0007] Preferably, the screening mechanism includes a lower support and an upper support fixed above the lower support. A feeding mold is provided on the top of the upper support, and a baffle plate is slidably connected inside the feeding mold. A cylinder A is installed on the side wall of the upper support, and the output shaft of cylinder A is fixedly connected to the baffle plate. A feeding port adapted to the feeding mold is opened on the lower support, and the feeding port is located directly above the feed end of the belt conveyor. By extending and retracting cylinder A, the opening and closing frequency of the baffle plate is controlled, thereby achieving quantitative and slow feeding of metal parts.

[0008] Preferably, the material distribution mechanism includes a material distribution trough installed on the side of the belt conveyor. A hinged seat is fixed on the side frame of the belt conveyor, and a material distribution plate is rotatably connected to the hinged seat. A servo motor is installed at the bottom or side of the hinged seat, and the output shaft of the servo motor is connected to the rotating shaft of the material distribution plate. The servo motor drives the material distribution plate to rotate and span across the belt, forming a rigid baffle that forces the parts to be guided smoothly into the material distribution trough.

[0009] Preferably, the sorting mechanism includes a mounting base, a guide plate is inclinedly arranged on the top of the mounting base, and the feeding end of the guide plate is connected to the bottom discharge end of the sorting trough; a mounting arm B is fixed on one side of the mounting base, and a CCD vision system is mounted on the cantilever end of the mounting arm B, and the detection lens of the CCD vision system faces the surface of the guide plate to obtain the appearance contour information of the accessories flowing through the guide plate.

[0010] Preferably, a mounting arm A is fixed to one side of the guide plate, and a cylinder B is horizontally mounted on the mounting arm A. The output end of the cylinder B is connected to a pusher plate, and the bottom of the pusher plate is disposed against or close to the surface of the guide plate. When the CCD vision system recognizes a specific accessory, it sends an electrical signal to the cylinder B, which then quickly extends to physically push the corresponding accessory out from the side of the guide plate.

[0011] Preferably, a baffle plate is provided at the discharge port of the guide plate, and a cylinder C is connected to the bottom of the baffle plate. The cylinder C is fixed to the lower part of the mounting base or an independent bracket. The cylinder C is used to drive the baffle plate to rise and fall. When the baffle plate rises, it can act as a physical interception at the end, and when it falls, it allows the parts to slide naturally from the end of the guide plate.

[0012] Preferably, a number of storage platforms are distributed below and to the side of the sorting mechanism, and a collection box is placed on the top of each storage platform; the end of the guide plate and the pushing direction of the pusher plate each correspond to a collection box, so as to realize the classified and centralized collection of accessories of different specifications or qualified / unqualified accessories.

[0013] Preferably, the end of the belt conveyor is fixed with a discharge chute, and the drive roller shaft of the belt conveyor is connected to a geared motor to provide stable and constant torque conveying power for the entire production line.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This automotive metal parts processing production line's sorting and conveying device uses a screening mechanism installed above the feed end of the belt conveyor. A cylinder-driven baffle plate opens and closes, enabling the quantitative and slow-moving of heavy, rigid metal parts. This purely mechanical physical buffering and guiding mechanism effectively prevents batch materials from haphazardly accumulating and squeezing at the front end of the conveyor belt, fundamentally solving the problem of production line jams and shutdowns due to dense material. This significantly improves the continuity and operational stability of the entire conveyor line and reduces manual unblocking costs.

[0015] The device features multiple servo-motor driven material distribution mechanisms along the side of the belt conveyor. Driven by the motors, the distribution plates span the belt surface, forming rigid physical baffles that guide heavy metal parts during transport smoothly and forcefully into their corresponding distribution troughs. Compared to traditional simple planar interception, this active rotary guide structure possesses extremely strong mechanical impact resistance, can stably adapt to various irregularly shaped automotive parts, completely eliminates the risk of physical lock-up at the distribution nodes, and ensures the reliability of the equipment during long-term operation.

[0016] This device innovatively employs a three-dimensional mechanical sorting structure combining a guide plate, a side pusher plate, and an end-lifting baffle plate at the sorting end. Triggered by basic electrical signals provided by the vision system, cylinders rapidly execute purely physical stripping actions such as side pushing or end-release, accurately placing the target metal parts into the corresponding collection bins. This multi-stage physical action not only offers rapid response but also boasts strong pneumatic structural components, effectively overcoming the fatigue and wear defects of traditional cantilever gripping systems, achieving impact-resistant sorting and centralized collection.

[0019] Please see Figures 1 to 7 The present invention provides a technical solution: a sorting and conveying device for an automotive metal parts processing production line.

[0020] This device uses belt conveyor 1 as the main transmission line; to ensure stable power output when transporting heavy-duty automotive metal parts, the drive roller shaft of belt conveyor 1 is directly connected to a geared motor 5; the end of belt conveyor 1 (i.e. the discharge end) is fixedly installed with a discharge trough 4, which is used to collect the remaining materials on the production line that have not been sorted in the middle.

[0021] The screening mechanism 2 is suspended directly above the feed end of the belt conveyor 1. Its main structure includes a lower support 21 and an upper support 22 fixed above the lower support 21 by a support column. A hollow feeding mold 23 is horizontally provided on the top of the upper support 22. A baffle plate 24 is horizontally slidably connected inside the feeding mold 23. A cylinder A25 is horizontally installed on one side of the outer wall of the upper support 22. The output push rod of the cylinder A25 passes through the side wall and is directly fixedly connected to the side end face of the baffle plate 24. A feeding port 26 is opened on the bottom plate of the lower support 21. The spatial position of the feeding port 26 is vertically connected to the internal channel of the feeding mold 23 and is vertically aligned with the center bearing surface of the belt conveyor 1.

[0022] Along the conveying direction of the belt conveyor 1, several group material distribution mechanisms 3 are arranged at equal intervals on one side. Each group material distribution mechanism 3 includes a material distribution trough 31 and a hinge seat 32. The hinge seat 32 is firmly installed on the side frame of the belt conveyor 1. The top of the hinge seat 32 is rotatably connected to a rigid material distribution plate 33 through a vertical rotating shaft. A servo motor 34 is fixed at the bottom or side of the hinge seat 32. The power output shaft of the servo motor 34 is directly connected to the rotating shaft of the material distribution plate 33, so that the material distribution plate 33 can be controlled to swing laterally above the belt. The material distribution trough 31 is arranged close to the guide side of the material distribution plate 33 and is used to receive metal parts blocked by the material distribution plate 33.

[0023] Each group of material distribution mechanism 3 has a sorting mechanism 6 connected to the end of the material distribution trough 31; the sorting mechanism 6 has an independent mounting base 61; the top of the mounting base 61 is fixed with a guide plate 62 at an inclination, and the higher feeding end of the guide plate 62 is smoothly connected to the bottom discharge end of the material distribution trough 31.

[0024] Side push assembly: A mounting arm A63 is fixed on one side of the guide plate 62, and a cylinder B64 is mounted horizontally (perpendicular to the material sliding direction) on the mounting arm A63; the telescopic end of the cylinder B64 is connected to a push plate 65, and the bottom edge of the push plate 65 maintains a slight gap or fits against the upper surface of the guide plate 62.

[0025] Visual inspection component: An L-shaped or gate-shaped mounting arm B67 is fixed on the other side of the mounting base 61. A CCD vision system 66 is vertically mounted on the top of the cantilever of the mounting arm B67. The inspection lens of the CCD vision system 66 faces the upper middle part of the guide plate 62, covering the necessary path for the accessory to slide down.

[0026] End release assembly: A baffle plate 68 that can slide up and down is provided in front of the lower discharge end of the guide plate 62; the bottom of the baffle plate 68 is connected to a vertically upward cylinder C69, and the cylinder C69 is fixed on the crossbeam below the mounting base 61.

[0027] Item collection: Several storage platforms 7 are distributed below the sorting mechanism 6 and around the sides of the pusher plate 65. A collection box 8 is placed on the top of the storage platform 7. Among them, a collection box 8 is placed directly below the end of the guide plate 62 to collect normally released accessories. Another collection box 8 is placed at the end of the side push track of the pusher plate 65 to collect rejected accessories.

[0028] The workflow of this device in an actual production line is as follows: Step 1: Quantitative feeding and buffering The automotive metal parts processed in the previous process are uniformly transported to the unloading mold 23 of the screening mechanism 2; the external control logic periodically controls the cylinder A25 to extend and retract, driving the baffle plate 24 to reciprocate within the unloading mold 23, thereby periodically opening and closing the material channel below; the metal parts are quantitatively and intermittently released through the unloading port 26 onto the continuously running belt conveyor 1 below; this mechanical action effectively disperses the dense parts and prevents heavy metal parts from piling up and clogging on the belt.

[0029] Step 2: Forced Physical Interception and Traffic Diversion As the metal parts move forward with the belt conveyor 1, when they reach a specific workstation that requires diversion, the servo motor 34 receives a trigger signal and starts, driving the material distribution plate 33 to rotate and span over the conveyor belt of the belt conveyor 1, forming a rigid physical interception surface. The metal parts are rigidly blocked here, and under the combined action of the friction of the conveyor belt and the inclined surface of the material distribution plate 33, their movement trajectory is changed accordingly, and they are forcibly guided to slide into the material distribution trough 31 on the side.

[0030] Step 3: Visual Recognition and Rapid Pneumatic Sorting Metal parts sliding out of the sorting trough 31 enter the sorting mechanism 6 and slide down along the inclined guide plate 62 under the action of gravity; when sliding directly under the CCD vision system 66, the vision system quickly captures the appearance outline image of the parts for feature verification.

[0031] Lateral rejection action: If the CCD vision system 66 identifies the part as a specification or defective product that needs to be rejected, the system will immediately output a switch signal to trigger the cylinder B64 to act; the cylinder B64 extends quickly, driving the pusher plate 65 to physically push the sliding part out from the side of the guide plate 62, and the part falls into the collection box 8 on the side.

[0032] End-of-line release and interception actions: If the CCD vision system 66 determines that the accessory is qualified and belongs to the target category, the side push action is not triggered, and the cylinder B64 remains in the retracted state; the accessory continues to slide down along the guide plate 62 to the end; at this time, if the accessory needs to be directly put into the box, the cylinder C69 is in the retracted state, the baffle plate 68 is lowered, and the accessory naturally slides into the collection box 8 directly below the end; if it is necessary to intercept or temporarily store qualified accessories, the cylinder C69 extends and lifts the baffle plate 68 to block the accessory's downward path.

[0033] Step 4: Waste material collection The remaining metal parts that are not intercepted by any of the grouping plates 33 on the production line eventually run to the end with the belt conveyor 1 and slide down and are discharged through the discharge chute 4, completing the sorting and conveying process of the entire production line.
