Description

Technical Field

[0001] This invention relates to the field of automotive parts screening technology, specifically to a powder metallurgy automotive parts finished product screening equipment. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, followed by forming and sintering, to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy shares similarities with ceramic production, both belonging to powder sintering technology. Powder metallurgy planetary gears are widely used in automotive parts, primarily for functioning as the reduction mechanism in starters. Compared to machined and cold-extruded gears, powder metallurgy gears offer higher precision and lower cost. With technological advancements and the continuous upgrading of high-tech products, defect detection is necessary to prevent substandard products from reaching the market. A search revealed Chinese patent application number "CN202220093181.7," which discloses a gear defect detection device, including a base, clamping components, a detection camera, and a controller. A clamping component is mounted on a base to hold the gear. A detection camera is also mounted on the base and connected to a controller. The camera captures images of the gear and sends the captured images to the controller, which processes and analyzes the images to output gear defect information. Compared to existing technologies, the gear defect detection device provided by this invention utilizes a clamping component mounted on a base and a controller connected to the detection camera.

[0003] However, existing technologies have the following problems during use: During use, only one part can be inspected at a time, and each part needs to be manually placed on the clamp after inspection. After the inspection is completed, the part is removed from the clamp, which is time-consuming and labor-intensive, reducing work efficiency.

[0004] Therefore, the present invention urgently needs to solve the problem of providing a powder metallurgy automotive parts screening equipment that can automatically feed materials and automatically classify and collect defective and non-defective finished parts during use, and can continuously perform online inspection of the parts to reduce inspection errors, saving time and effort and improving work efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, the purpose of this invention is to overcome the limitations of existing technologies, which only allow for the inspection of one component at a time. Furthermore, each component requires manual placement onto a clamping device, followed by removal after inspection, resulting in time-consuming, labor-intensive, and inefficient work.

The interior of the feeding box is divided into a feeding chamber and a discharging chamber by a partition. The material box is vertically fixed through the discharging chamber, and a discharge port for use with the parts is opened on the partition facing the upper open end of the material box. A liftable lifting plate is horizontally and through the interior of the feeding box. A guide plate inclined towards the discharge port is provided on the top of the lifting plate. The top part of the guide plate is recessed inward to form a limiting groove for use with the parts.

[0008] Preferably, the upper end of the support base opposite the bottom opening of the material box has a material discharge opening.

The movable plate is provided with a material discharge port that cooperates with the material discharge opening and the bottom opening of the material box. The side wall of the material box has a clearance window that communicates with the interior of the second component at the bottom. A top plate that can pass through the clearance window and abut against the component is horizontally fixed on the movable plate by a tensioning member.

[0009] Preferably, a guide trough with its end portion extending from the side wall of the cabinet and reaching the upper end of the rotary table is horizontally fixed below the support base located at the material discharge opening, and a belt conveyor mechanism is horizontally provided on the inner wall of the guide trough.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] like Figure 1-9 As shown, the present invention provides a powder metallurgy automotive parts finished product screening equipment, including a base 1, a cabinet 2 vertically fixed on the upper end of the base 1, a rotating disk 3 made of transparent glass and horizontally rotatable inside the cabinet 2, a feeding mechanism 13 located beside the rotating disk 3 and capable of uniformly feeding materials to its upper end, a visual inspection component located along the rotation direction of the rotating disk 3 and respectively located on the upper and lower sides of the rotating disk 3 and capable of visually inspecting the upper, lower, and side parts of the parts on the rotating disk 3, and a recycling component located at the unloading end of the rotating disk 3 and classifying and collecting defective and good products after visual inspection.

[0022] In the above scheme, the feeding mechanism 13 intermittently feeds parts (gears) to the upper end of the rotating disk 3. During rotation, each part fed by the feeding mechanism 13 passes sequentially through the vision inspection component, which detects defects in each part. After inspection, the gear, under the rotation of the rotating disk 3, passes through the recycling component, which sorts and collects defective and non-defective parts. The entire process requires no manual operation, saving manpower and improving work efficiency.

[0023] In a preferred embodiment of the present invention, the feeding mechanism 13 includes: a first feeding mechanism 1301 and a second feeding mechanism 1302. The first feeding mechanism 1301 includes: a feeding box 130101, a lifting plate 130102, and a guide plate 130103; the second feeding mechanism 1302 includes: a material box 130201, a moving plate 130202, and a top plate 130203, wherein... A support base 16 is vertically fixed at the upper end of the base 1. A feeding box 130101 is vertically fixed above the support base 16. The interior of the feeding box 130101 is divided into a feeding chamber and a discharging chamber by a partition. A material box 130201 is vertically fixed through the discharging chamber. A discharge port 17 for use with parts is provided on the partition facing the upper open end of the material box 130201. A liftable lifting plate 130102 is horizontally and through the interior of the feeding box 130101. A guide plate 130103 inclined towards the discharge port 17 is provided on the top of the lifting plate 130102. The top part of the guide plate 130103 is recessed inward to form a limiting groove for use with parts.

[0024] In the above scheme, during use, an appropriate number of gears are placed into the upper opening of the feeding box 130101. Then, the lifting plate 130102 is driven to reciprocate vertically within the feeding box 130101, thereby causing the guide plate 130103 at its top to rise and fall. During the rising and falling process, the gears in the feeding box 130101 fall into the limiting groove at the top of the guide plate 130103, thus grabbing the gears in the feeding box 130101. The guide plate 130103 rises to its bottom end and is aligned with the bottom of the discharge port 17 on the partition. When the gears are aligned, the limiting grooves grip the gears inside the feeding box 130101. The gears roll along the inclined limiting grooves through the discharge port 17 into the discharge chamber and fall into the material box 130201. The inner length of the material box 130201 is equal to the diameter of the gears, and its inner width is equal to the thickness of the gears. Therefore, the first feeding mechanism 1302 can automatically feed multiple gears into the material box 130201 in sequence and stack them neatly inside the material box 130201, so that the second feeding mechanism 1302 can intermittently transport the gears inside to the rotating disk 3 one by one.

[0025] Therefore, the first feeding mechanism 1301 sequentially feeds the parts to the second feeding mechanism 1302, so that the parts are arranged on the second feeding mechanism 1302. The second feeding mechanism 1302 then intermittently feeds the parts to the rotating disk 3, so that the rotating disk 3 passes each part sequentially through the visual inspection component and the recycling component during rotation, so as to classify and collect defective parts and non-defective parts.

[0026] In summary, the feeding mechanism 13 can arrange the parts in an orderly manner and then transport the arranged parts to the rotating disk 3 in sequence. The rotating disk will then pass each part through the vision inspection component and the recycling component to classify and collect the parts with defects and the parts without defects. This not only realizes the function of automatic feeding but also the function of continuous inspection, thus improving work efficiency.

[0027] In addition, a reduction motor for driving the rotating disk 3 to rotate is vertically fixed on the base 1, and the output shaft of the reduction motor is fixed at the center position of the bottom of the rotating disk 3.

[0028] In a preferred embodiment of the present invention, a material discharge opening is provided at the upper end of the support base 16 facing the bottom opening of the material box 130201. A horizontally movable movable plate 130202, capable of sealing the material discharge opening of the support base 16 and the bottom opening of the material box 130201, is provided between the material box 130201 and the support base 16. The movable plate 130202 is provided with a material discharge port 18 that cooperates with the material discharge opening and the bottom opening of the material box 130201. A clearance window 19 communicating with the interior of the material box 130201 is provided on the side wall of the material box 130201 at the position of the second component at its bottom. A top plate 130203, capable of passing through the clearance window 19 and abutting against the component, is horizontally fixed on the movable plate 130202 by a tensioning member.

[0029] In the above scheme, when using it, such as Figure 8 and 9 As shown, when the material discharge port 18 of the moving plate 130202 is located beside the material box 130201, the moving plate 130202 blocks the bottom opening of the material box 130201 and the material discharge opening at the top of the support base 16. At the same time, the top plate 130203 is also located beside the material box 130201. At this time, the state of the second feeding mechanism 1302 is as follows. Figure 8As shown. When the moving plate 130202 drives the top plate 130203 toward the material box 130201, so that the material drop port 18 on the moving plate 130202 moves to be aligned in the longitudinal direction with the bottom window of the material box 130201 and the material drop opening at the top of the support base 16, the bottom opening of the material box 130201 is opened. Under its own weight, the gear located at the lowest point of the material box 130201 passes through the bottom opening of the material box 130201, the material drop port 18 on the moving plate 130202, and the material drop opening on the support base 16 in sequence, falling into the guide groove 14. The gear is then transported to the rotating disk 3 by the belt conveyor mechanism 15 in the guide groove 14, so that the rotating disk 3 passes through the vision inspection component and the recycling component in sequence during rotation. Before the top plate 130203 moves horizontally with the moving plate 130202 to align with the bottom window of the material box 130201 and the upper opening of the support base 16 in the longitudinal direction, the moving plate 130202 drives the top plate 130203 to move towards the material box 130201 and abut against the gear inside it. As the moving plate 130202 continues to move forward until the bottom window 18 is aligned with the bottom window of the material box 130201 and the upper opening of the support base 16 in the longitudinal direction, the moving plate 130202 always abuts against the second gear from bottom to top in the material box 130201, and the tensioning member is gradually compressed to be in a compressed state. Under the action of the compressed tensioning member, the top plate 130203 always abuts against the corresponding gear inside the material box 130201. Figure 9 As shown, this is to prevent the corresponding gear and other gears stacked on top of it from falling out of the bottom opening of the material box 130201, thereby achieving an intermittent, one-to-one feeding function.

[0030] Therefore, the moving plate 130202 is moved back and forth in the manner described above to achieve the function of intermittent, sequential feeding.

[0031] In a preferred embodiment of the present invention, a guide trough 14 is horizontally fixed below the support base 16 located at the material discharge opening, with its end portion passing through the side wall of the cabinet 2 and extending to the upper end of the rotating disk 3, and a belt conveyor mechanism 15 is horizontally arranged on the inner wall of the guide trough 14.

[0032] In the above scheme, the belt conveyor mechanism 15 can sequentially transport the gears that fall into the guide trough 14 to their ends and fall onto the rotating disk 3, thereby playing a conveying role.

[0033] The belt conveyor mechanism 15 includes a belt and belt rollers. Two belt rollers are horizontally and rotatably arranged at both ends of the guide trough 14, and a belt is sleeved between them. The end of any one belt roller passes through the inside of the guide trough 14 and is coaxially connected to a servo motor that is horizontally fixed on the outer wall of the guide trough 14 through a coupling.

[0034] In a preferred embodiment of the present invention, the tensioning element includes: a tension spring and a push rod; wherein, A push rod is horizontally and movably installed on the movable plate 130202, and a top plate 130203 is fixedly installed at the end of the push rod. A tension spring is sleeved on the push rod located between the top plate 130203 and the movable plate 130202, and the two ends of the tension spring are respectively fixed on the top plate 130203 and the movable plate 130202. An electric telescopic rod for driving the lifting plate 130102 to rise and the movable plate 130202 to move horizontally is also fixedly installed at the upper end of the support base 16.

[0035] In the above scheme, the electric telescopic rod can be a pneumatic cylinder, a hydraulic cylinder, or a servo electric cylinder.

[0036] In use, two electric telescopic rods are used to drive the moving plate 130202 on the support plate 16 to move linearly in the horizontal direction and to drive the lifting plate 130102 to move vertically in the vertical direction, thus providing power for both.

[0037] In addition, the movable plate 130202 is also provided with a guide hole for the push rod to pass through, so that the push rod and the guide hole of the movable plate 130202 play a guiding role, so that the top plate 130203 moves back and forth in a straight line in the horizontal direction with the movable plate 130202. When the movable plate 130202 drives the top plate 130203 to move towards the material box 130201 and abut against the gear inside it, when the movable plate 130202 continues to move forward, the movable plate 130202 pushes the tension spring on the push rod to compress it. Under the action of the compressed tension spring, the top plate 130203 always abuts against the corresponding gear inside the material box 130201, so as to prevent the corresponding gear and other gears stacked on it from falling out of the bottom opening of the material box 130201, thereby realizing the intermittent one-to-one feeding function.

[0038] The top plate 130203 is also horizontally fixed with a pin that can pass through the through hole in the middle of the gear. The pin can be a frustum-shaped cylinder with a gradually increasing diameter, so as to further support the corresponding gear and other gears stacked on it.

[0039] In addition, at least two guide rails are fixedly and horizontally at intervals at the top of the support base 16, and the bottom of the movable plate 130202 is recessed inward at intervals to form two guide grooves that cooperate with the two guide rails. The movable plate 130202 is horizontally and slidably mounted on the two guide rails through these two guide grooves. This serves as a guide, allowing the movable plate 130202 to move linearly back and forth on the support base 16.

[0040] In a preferred embodiment of the present invention, the visual detection component includes: a first camera 4, a second camera 5, and a third camera; wherein, A first bracket and a second bracket are vertically fixed and spaced apart between the feeding mechanism 13 and the recycling component, along the rotation direction of the rotating disk 3. A first camera 4 capable of visually inspecting the side of the component is horizontally fixed on the first bracket, which is located on the rotating disk 3. A second camera 5 and a third camera capable of visually inspecting the top and bottom surfaces of the component are vertically fixed on the second brackets located on the upper and lower sides of the rotating disk 3, respectively.

[0041] In the above scheme, the cabinet 1 is also equipped with a display screen and a controller that are electrically connected to the first camera 4, the second camera 5 and the third camera. The display screen is used to display the outline of the gear, and the controller is used to process and analyze the image information to output the defect information of the gear and control the electrical components of the entire device to work together.

[0042] In use, the first camera 4, the second camera 5, and the third camera can respectively capture images of the tooth surface and both end faces of each gear passing through, and send the captured image information to the controller. The controller processes and analyzes the image information to output the defect information of the gear. This allows a visual inspection component to determine whether the gear has defects.

[0043] Therefore, the detection component enables continuous online inspection of parts, saving time and effort and improving work efficiency.

[0044] In a preferred embodiment of the present invention, the recycling assembly includes: a recycler 7, a feed hopper 8, a pneumatic nozzle 9, and a baffle 10; wherein, A hollow-structured recycler 7 is vertically fixed to the base 1 located next to the first bracket. An inlet communicating with the interior of the recycler 7 is opened on the upper surface of the rotating disk 3. A pneumatic nozzle 9 is provided above the rotating disk 3, inclined towards the inlet, to blow parts from the upper end of the rotating disk 3 into the recycler 7. A feed hopper 8 with an open opening facing upward is vertically fixed below the rotating disk 3 located next to the recycler 7. A baffle 10 capable of guiding parts into the feed hopper 8 is horizontally fixed to the upper end of the rotating disk 3 located next to the feed hopper 8.

[0045] In the above scheme, before use, the pneumatic nozzle 9 is connected to an external pneumatic actuator, and the pneumatic actuator sprays gas through the starting nozzle 9. Another method is to connect the pneumatic nozzle 9 to a gas storage tank containing compressed gas through an air pipe, and a solenoid valve is installed on the air pipe. The solenoid valve controls the connection between the pneumatic nozzle 9 and the gas storage tank, thereby controlling whether the pneumatic nozzle 9 sprays gas.

[0046] In use, as the rotating disk 3 rotates slowly (counterclockwise), the gears that fall onto the rotating disk 3 from the feeding mechanism 13 pass through the vision inspection component to visually inspect each gear to detect whether there are any defects. After the defective gear is detected by the camera of the vision inspection component, when the defective gear passes through the recycling unit 7, the start nozzle 9 blows air into the defective gear, i.e., the defective product, to blow it into the recycling unit 7. The defective product, which is a good product, continues to be rotated by the rotating disk 3 until it meets the baffle 10. It is blocked by the baffle 10 and, under the action of the centrifugal force of the rotating disk 3, slides along the baffle 10 towards the feed hopper 8 and falls into the feed hopper 8, thereby completing the automatic separation and recycling function, picking out the defective products and the good products for recycling.

[0047] In a preferred embodiment of the present invention, the bottom ends of the recycler 7 and the feed hopper 8 are respectively connected and fixedly provided with a first discharge pipe 11 and a second discharge pipe 12 extending from the inside of the base 1.

[0048] In the above scheme, receiving frames corresponding to the first discharge pipe 11 and the second discharge pipe 12 can be placed horizontally on both sides of the base 1 to receive defective products and good products discharged from both sides respectively.

[0049] The first discharge pipe 11 and the second discharge pipe 12 can be corrugated hoses.

[0050] In summary, the powder metallurgy automotive parts screening equipment provided by this invention overcomes the problems of existing technologies that can only inspect one part at a time, and that each part needs to be manually placed on the clamping device and removed from the clamping device after inspection, which is time-consuming, labor-intensive, and reduces work efficiency.
