Description

Technical Field

[0001] This invention relates to the field of brass rod testing technology, specifically to an intelligent testing and screening device for brass rod production and its usage method. Background Technology

[0002] Brass bars are processed rods with copper-zinc alloy as the main component. They are classified into three categories according to processing technology: hot-forged, cold-forged, and galvanized brass bars. They contain 56%-68% copper, have a melting point of 934-967℃, and possess electrical conductivity, wear resistance, and corrosion resistance. They are widely used in instrument parts, ship components, automotive synchronizer gear rings, and other fields. Material grades include H59, H62, C3604, and others. Production processes cover extrusion, continuous casting, rolling, and stretching. Extrusion processes are divided into forward, reverse, and special extrusion types.

[0003] Existing technologies require testing after processing before they can be put into use. The traditional testing method involves manual measurement of parts using handheld testing tools, which is inefficient and cannot meet normal production needs.

[0004] To address the aforementioned problems, existing technologies offer a solution. For example, patent publication number CN114472220B provides an intelligent inspection device for forged fork-shaped parts and its usage method, relating to the field of workpiece inspection technology. The device includes a sorting mechanism comprising a first movable rod penetrating a disc, with a second movable rod symmetrically arranged on the disc. A lifting mechanical claw electrically connected to a controller is fixedly connected to the bottom of the first movable rod. During inspection, if the fork-shaped part being inspected is a defective product, it cannot pass through the inspection fixture and push the fixture to move. At this time, the sensor cannot detect the position of the inspection fixture and transmits a signal to the controller. The controller then transmits the signal to the conveyor... The first servo motor (61) is started and drives the disc to rotate, so that the lifting mechanical claw grabs the unqualified fork-shaped parts, so that the unqualified products are screened out and transported out with the operation of the conveyor. The intelligent replaces the manual and increases the work efficiency. After the brass rod is processed, the size needs to be inspected to prevent the brass rods that do not meet the usage size from being mixed into the qualified brass rods. However, the existing device usually directly separates the qualified and unqualified brass rods after the inspection. During the separation process, the brass rods are directly pushed to both sides, and then the brass rods will roll down in various postures. This can easily cause the brass rods to collide when rolling, which can easily cause the brass rods to be damaged.

[0005] Therefore, an intelligent detection and screening device for brass rod production and its usage method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent detection and screening device for brass rod production and its usage method, thereby solving the above-mentioned problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An intelligent inspection and screening device for brass rod production includes a conveyor line, an inspection device, and a material collection platform. It also includes a mounting base, a cylinder, a conveying mechanism, a main gripper, a connecting mechanism, a secondary gripper, and a drive rack. The mounting base is fixedly connected to the conveyor line, the cylinder is fixedly connected to the mounting base, the conveying mechanism is connected to the cylinder, the main gripper is connected to the conveying mechanism, the connecting mechanism is connected to the main gripper, and the secondary gripper, drive rack, and connecting rack are all connected to the connecting mechanism. After inspecting the brass rod, the inspection device controls the cylinder to start based on the inspection result and controls the main gripper and secondary gripper to clamp the brass rod through the conveying mechanism. After the brass rod is clamped, the connecting mechanism operates under the action of the drive rack and controls the secondary gripper to move out of position to guide the brass rod to fall onto the material collection platform.

[0008] Optionally, after the inspection is completed, the brass rod can be directly pushed off the conveyor line by a pusher plate, or it can be removed from the conveyor line by handling. If the brass rod is pushed off directly, the distance the brass rod moves during unloading will be increased, which may easily cause the brass rod to collide and thus damage its surface. However, if the brass rod is removed from the conveyor line by clamping and handling, it can be ensured that the brass rod is unloaded in a stable posture, which can avoid collisions caused by the rolling of the brass rod during unloading. Therefore, the method of directly pushing the brass rod off the conveyor line is not used.

[0009] Preferably, the conveying mechanism includes a servo motor, a lead screw, a threaded block, a mounting plate, a guide block, a guide rod, and a clamping unit. The servo motor is fixedly mounted on one end of the mounting base. The detection device and the cylinder are electrically connected to the servo motor. The lead screw is fixedly mounted on the output end of the servo motor. The threaded block is threadedly connected to the lead screw. The mounting plate is fixedly mounted on the top of the threaded block. The cylinder is fixedly mounted on the top of the mounting plate. The guide block is fixedly mounted on the bottom end of the mounting plate. The guide rod is slidably connected to the guide block. The clamping unit is connected to the threaded block and the guide block respectively.

[0010] Preferably, the mounting base is provided with a threaded groove, a through groove and a guide groove, the threaded groove and the guide groove are symmetrically arranged with the through groove as the center, the lead screw and the threaded block are both installed in the threaded groove, the guide block and the guide rod are both installed in the guide groove, the length of the threaded groove, the through groove and the guide groove are the same, and the length of the threaded groove, the through groove and the guide groove is greater than the width of the conveyor line.

[0011] Preferably, the clamping unit includes a fixed base, a connecting rod, a limiting block, a limiting rod, a spring, and a connecting plate. The fixed base is fixedly installed at the bottom end of the threaded block and the guide block. The connecting rod is hinged to the fixed base. The limiting block is hinged to one end of the connecting rod. The limiting rod is slidably connected to the limiting block. The connecting plate is fixedly connected to the limiting rod. The spring is fixedly installed between the limiting block and the connecting plate. The main gripper is fixedly connected to the limiting block.

[0012] Preferably, the connecting plate has two sets of symmetrically arranged limiting grooves inside, and each set of limiting grooves has two symmetrically arranged around the center line of the connecting plate. The limiting block, limiting rod and spring are all installed in the limiting groove.

[0013] Optionally, a guiding device can be installed on the material collection platform. The guiding device has an opening to guide the brass rod falling onto the material collection platform, preventing the brass rod from being deflected and damaged when it slides off the platform. When transferring the brass rod to the material collection platform, it can be pushed directly onto the platform or transferred by clamping. If the pushing method cannot guarantee the posture of the brass rod on the material collection platform, it cannot guarantee that the brass rod will fall accurately into the guiding device on the platform. This can easily lead to damage due to collision between the brass rod and the guiding device. The clamping method can accurately align the brass rod with the guiding device, thus ensuring the posture of the brass rod when entering the guiding device and avoiding excessive friction and collision between the brass rod and the guiding device. Therefore, the clamping method is used to move the brass rod onto the material collection platform.

[0014] Preferably, the connecting mechanism includes a drive gear, a vertical rod, a screw, a vertical rack, a limiting plate, a connecting gear, a helical rack, a connecting block, and a connecting rod. The drive gear meshes with the drive rack, the vertical rod is fixedly installed at the bottom end of the drive gear, the screw is slidably connected to the vertical rod, the vertical rack is threadedly connected to the screw, the limiting plate is fixedly installed at one end of the vertical rack, the connecting gear meshes with the vertical rack, the helical rack meshes with the connecting gear, the connecting block is fixedly installed at one end of the helical rack, and the connecting rod is slidably connected to the connecting block.

[0015] Preferably, the vertical rod includes a connecting part and a limiting part, the connecting part is fixedly connected to the drive gear, and the screw has a limiting hole inside that cooperates with the limiting part.

[0016] Preferably, the main gripper has two sets of symmetrical connecting grooves inside, and the connecting block and connecting rod are both installed in the connecting grooves. The connecting groove has a T-shaped cross-section and is open on both sides.

[0017] Preferably, when the cylinder is not started, the axis of the drive gear coincides with the center line of the drive rack. The drive rack is provided in two sets, and each set of the drive rack has two racks. Each set of the drive rack is centrally symmetrical about the center line of the mounting base.

[0018] A method for using an intelligent detection and screening device for brass rod production includes the following steps: S1: When the detection device detects the brass rods on the conveyor line, it sequentially starts the cylinder and servo motor according to the detection results. The cylinder drives the mounting plate to descend. When the mounting plate descends, it drives the limit block to descend synchronously and slide synchronously on the limit rod. When the mounting plate descends, the vertical rod slides in the screw. When the limit block slides and squeezes the spring, it drives the two sets of main jaws and auxiliary jaws to descend to below the axis of the brass rod. Then the two sets of main jaws and auxiliary jaws move towards each other to grab the brass rod. S2: After the main gripper and the auxiliary gripper grasp the brass bar, the servo motor starts immediately. When the servo motor starts, it drives the lead screw to rotate. When the lead screw rotates, it drives the cylinder, main gripper, auxiliary gripper and brass bar to move horizontally through the mounting plate. When the mounting plate moves horizontally, the drive gear meshes with the drive rack. When the drive gear rotates, it drives the screw to rotate through the vertical rod. When the screw rotates, the two sets of drive gears rotate in opposite directions and mesh with the drive rack to drive the screw to rotate. S3: When the screw rotates, it drives one set of vertical racks to rise and the other set of vertical racks to fall. When the vertical racks move, they drive the connecting gear to rotate. When the connecting gear rotates, it drives one of the two helical racks to move obliquely upward and the other obliquely downward. When the helical racks move, they drive the connecting block to slide on the connecting rod. At the same time, they drive the secondary grippers to move synchronously. The two secondary grippers move obliquely upward and downward, and are misaligned to facilitate the unloading of the brass rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The main gripper and the auxiliary gripper are controlled by the cylinder to descend synchronously to the lower part of the axis on both sides of the brass rod. Then they move towards each other to control the auxiliary gripper to fit tightly with the brass rod. Under pressure, the brass rod is squeezed upward to separate the brass rod from the conveyor line, thus achieving the initial clamping of the brass rod.

[0020] 2. The main jaw, secondary jaw, and brass rod are moved horizontally by the servo motor driving the lead screw. When moving, one set of secondary jaws moves obliquely upward while the other set moves obliquely downward, thereby achieving the misalignment of the two sets of secondary jaws to increase the gap at the bottom of the two sets of secondary jaws, thus facilitating the unloading of the brass rod.

[0021] 3. The contact surface between the secondary grippers and the brass rod is made of rubber. When the two sets of secondary grippers move in opposite directions, friction is generated between them and the brass rod. Under the action of the reverse friction force, the brass rod is controlled to produce a slight vibration, thereby adjusting the posture of the brass rod between the two secondary grippers and ensuring that the brass rod is fed in a stable posture.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. However, the embodiments described below are only some embodiments of the present invention, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present invention.

[0025] Reference Figures 1 to 8 A smart inspection and screening device for brass rod production includes a conveyor line 1, an inspection device 2, and a material collection platform 3. It also includes a mounting base 4, a cylinder 5, a conveying mechanism 6, a main gripper 7, a connecting mechanism 8, a secondary gripper 9, and a drive rack 10. The mounting base 4 is fixedly connected to the conveyor line 1, the cylinder 5 is fixedly connected to the mounting base 4, the conveying mechanism 6 is connected to the cylinder 5, the main gripper 7 is connected to the conveying mechanism 6, the connecting mechanism 8 is connected to the main gripper 7, and the secondary gripper 9, the drive rack 10, and the connecting rack are all connected to the connecting mechanism 8. The surface of the secondary gripper 9 is made of rubber. Made of a material that increases the friction between the secondary gripper 9 and the brass rod, it not only prevents the brass rod from falling quickly, but also generates a slight vibration when the two secondary grippers 9 move in opposite directions, thereby adjusting the posture of the brass rod. After the detection device 2 detects the brass rod, it controls the cylinder 5 to start according to the detection result and controls the main gripper 7 and the secondary gripper 9 to cooperate in clamping the brass rod through the conveying mechanism 6. After the brass rod is clamped, the connecting mechanism 8 runs under the action of the drive rack 10 and controls the secondary gripper 9 to move in a misaligned manner to guide the brass rod to fall to the guide collection table 3.

[0026] As one embodiment of the present invention, refer to Figure 2 , Figure 3 , Figure 4 and Figure 6The conveying mechanism 6 includes a servo motor 61, a lead screw 62, a threaded block 63, a mounting plate 64, a guide block 65, a guide rod 66, and a clamping unit 67. The servo motor 61 is fixedly mounted on one end of the mounting base 4. The detection device 2 and the cylinder 5 are electrically connected to the servo motor 61. The lead screw 62 is fixedly mounted on the output end of the servo motor 61. The threaded block 63 is threadedly connected to the lead screw 62. The mounting plate 64 is fixedly mounted on the top of the threaded block 63. The cylinder 5 is fixedly mounted on the top of the mounting plate 64. The guide block 65 is fixedly mounted on the bottom of the mounting plate 64. The guide rod 66 is slidably connected to the guide block 65. The clamping unit 67 is connected to the threaded block 63 and the guide block 65 respectively. The mounting base 4 is provided with a threaded groove 68, a through groove 69, and a guide groove 610. The threaded groove 68 and the guide groove 610 are symmetrically arranged with the through groove 69 as the center. Through the above arrangement, the movement of the threaded block 63 and the guide block 65 is kept balanced. This design prevents the threaded block 63 and guide block 65 from causing the mounting plate 64 to skew, thus maintaining the stability of the device. The screw 62 and threaded block 63 are both installed in the threaded groove 68, which provides space for their movement. The guide block 65 and guide rod 66 are both installed in the guide groove 610, which provides space for their movement. The threaded groove 68, through groove 69, and guide groove 610 have the same length, ensuring that the threaded block 63, guide block 65, and cylinder 5 move the same distance. The length of the threaded groove 68, through groove 69, and guide groove 610 is greater than the width of the conveyor line 1. This design allows the main gripper 7 and secondary gripper 9 to control the brass rod to move to the outside of the conveyor line 1, facilitating its movement above the material guiding device on the material collecting platform 3.

[0027] As one embodiment of the present invention, refer to Figures 4 to 7The clamping unit 67 includes a fixed base 671, a connecting rod 672, a limiting block 673, a limiting rod 674, a spring 675, and a connecting plate 676. The fixed base 671 is fixedly installed on the bottom of the threaded block 63 and the guide block 65. The connecting rod 672 is hinged to the fixed base 671. The limiting block 673 is hinged to one end of the connecting rod 672. The limiting rod 674 is slidably connected to the limiting block 673. The connecting plate 676 is fixedly connected to the limiting rod 674. The spring 675 is fixedly installed between the limiting block 673 and the connecting plate 676. Through the setting of the spring 675, the main gripper can be driven by the limiting block 673. When the main gripper 7 moves towards the secondary gripper 9, it acts as a buffer. At the same time, it provides power when the brass rod is transferred to the guide collection table 3 and then resets. The main gripper 7 is fixedly connected to the limiting block 673. The connecting plate 676 has two sets of limiting grooves 677 symmetrically arranged inside. Each set of limiting grooves 677 has two symmetrically arranged around the center line of the connecting plate 676. Through the above arrangement, the movement of the limiting block 673 can be kept balanced. The limiting block 673, the limiting rod 674 and the spring 675 are all installed in the limiting groove 677. The setting of the limiting groove 677 provides space for the movement of the limiting block 673.

[0028] As one embodiment of the present invention, refer to Figures 5 to 8The connecting mechanism 8 includes a drive gear 81, a vertical rod 82, a screw 83, a vertical rack 84, a limiting plate 85, a connecting gear 86, a helical rack 87, a connecting block 88, and a connecting rod 89. The drive gear 81 meshes with the drive rack 10. The vertical rod 82 is fixedly installed at the bottom end of the drive gear 81. The screw 83 is slidably connected to the vertical rod 82. The vertical rack 84 is threadedly connected to the screw 83. The limiting plate 85 is fixedly installed at one end of the vertical rack 84. The connecting gear 86 meshes with the vertical rack 84. The helical rack 87 meshes with the connecting gear 86. The connecting block 88 is fixedly installed at one end of the helical rack 87. The connecting rod 89 slides with the connecting block 88. The vertical rod 82 includes a connecting part 821 and a limiting part 822. The connecting part 821 is fixedly connected to the drive gear 81. The connecting part 821 guides the vertical rack 84 during the lifting and lowering of the connecting plate 676. The screw 83 has a limiting hole inside that mates with the limiting part 822. This limiting hole controls the limiting part 822 to only lift and lower, thus causing the screw 83 to rotate simultaneously with the drive gear 81 driving the vertical rod 82. The main gripper 7 has two symmetrically arranged connecting grooves 810 inside. The connecting block 88 and the connecting rod 89 are both installed in the connecting grooves 810. The connecting groove 810 provides space for the movement of the connecting block 88. The connecting groove 810 has a T-shaped cross-section and is open on both sides. This design allows the connecting block 88 to simultaneously connect the helical rack 87 and the secondary gripper 9. When the cylinder 5 is not activated, the axis of the drive gear 81 coincides with the center line of the drive rack 10. This design ensures that the drive gear 81 can rotate regardless of whether the brass rod's inspection result is satisfactory. When the drive gear 81 moves outward from the mounting base 4 and then inward from the mounting base 4, the vertical rack 84 can be adjusted in height. The drive rack 10 has two sets of components for this movement. Each set of drive racks 10 has two racks, and each set of drive racks 10 is centrally symmetrical about the center line of the mounting base 4. Through the above arrangement, the two sets of drive gears 81 can be controlled to rotate in opposite directions, thereby controlling the two sets of connecting mechanisms 8 to move in opposite directions. This, in turn, controls the two sets of secondary grippers 9 to move one obliquely upward and the other obliquely downward, so as to control the misaligned movement of the two sets of secondary grippers 9 to control the brass rod to be unloaded while generating slight vibration. This achieves fine adjustment of the posture of the brass rod, so as to ensure that the brass rod falls accurately into the guiding device of the guiding collection platform 3 with a stable posture, thereby avoiding the collision between the brass rod and the guiding collection platform 3 due to unstable posture.

[0029] A stamping method for an intelligent inspection and screening device used in the production of brass bars includes the following steps: S1: When the detection device 2 detects the brass rod on the conveyor line 1, it sequentially starts the cylinder 5 and the servo motor 61 according to the detection result. The cylinder 5 drives the mounting plate 64 to descend. When the mounting plate 64 descends, it drives the limit block 673 to slide synchronously on the limit rod 674 while descending synchronously. When the mounting plate 64 descends, the vertical rod 82 slides in the screw 83. When the limit block 673 slides and squeezes the spring 675, it drives the two sets of main grippers 7 and secondary grippers 9 to descend to below the axis of the brass rod. Then the two sets of main grippers 7 and secondary grippers 9 move towards each other to grab the brass rod. S2: After the main gripper 7 and the secondary gripper 9 grip the brass rod, the servo motor 61 starts immediately. When the servo motor 61 starts, it drives the lead screw 62 to rotate. When the lead screw 62 rotates, it drives the cylinder 5, the main gripper 7, the secondary gripper 9 and the brass rod to move horizontally through the mounting plate 64. When the mounting plate 64 moves horizontally, the drive gear 81 meshes with the drive rack 10. When the drive gear 81 rotates, it drives the screw 83 to rotate through the vertical rod 82. When the screw 83 rotates, the two sets of drive gears 81 rotate in opposite directions and mesh with the drive rack 10 to drive the screw 83 to rotate. S3: When the screw 83 rotates, it drives one set of vertical racks 84 to rise and the other set of vertical racks 84 to fall. When the vertical racks 84 move, they drive the connecting gear 86 to rotate. When the connecting gear 86 rotates, it drives one of the two helical racks 87 to move obliquely upward and the other obliquely downward. When the helical racks 87 move, they drive the connecting block 88 to slide on the connecting rod 89. At the same time, they drive the secondary grippers 9 to move synchronously. The two secondary grippers 9 move obliquely upward and downward, and are misaligned to facilitate the unloading of the brass rod.

The connecting part (821) is fixedly connected to the drive gear (81). The screw (83) has a limiting hole inside that cooperates with the limiting part (822).

8. The intelligent detection and screening equipment for brass rod production according to claim 7, characterized in that: The main gripper (7) has two sets of symmetrical connecting grooves (810) inside. The connecting block (88) and the connecting rod (89) are both installed in the connecting grooves (810). The connecting groove (810) has a T-shaped cross section and is open on both sides.

9. The intelligent detection and screening equipment for brass rod production according to claim 8, characterized in that: When the cylinder (5) is not started, the axis of the drive gear (81) coincides with the center line of the drive rack (10). There are two sets of drive racks (10), and each set of drive racks (10) has two racks. Each set of drive racks (10) is centrally symmetrical about the center line of the mounting base (4).

10. A method of using the intelligent detection and screening equipment for the production of brass rods according to any one of claims 1-9, characterized in that, Includes the following steps: S1: When the detection device (2) detects the brass rod on the conveyor line (1), it starts the cylinder (5) and the servo motor (61) in sequence according to the detection result. The cylinder (5) drives the mounting plate (64) to descend. When the mounting plate (64) descends, it drives the limit block (673) to descend synchronously and slide synchronously on the limit rod (674). When the mounting plate (64) descends, the vertical rod (82) slides in the screw (83). When the limit block (673) slides and squeezes the spring (675), it drives the two sets of main jaws (7) and secondary jaws (9) to descend to below the axis of the brass rod. Then the two sets of main jaws (7) and secondary jaws (9) move towards each other to grab the brass rod. S2: After the main gripper (7) and the secondary gripper (9) grip the brass rod, the servo motor (61) starts immediately. When the servo motor (61) starts, it drives the lead screw (62) to rotate. When the lead screw (62) rotates, it drives the cylinder (5), the main gripper (7), the secondary gripper (9) and the brass rod to move horizontally through the mounting plate (64). When the mounting plate (64) moves horizontally, the drive gear (81) meshes with the drive rack (10). When the drive gear (81) rotates, it drives the screw (83) to rotate through the vertical rod (82). When the screw (83) rotates, the two sets of drive gears (81) rotate in opposite directions and mesh with the drive rack (10) to drive the screw (83) to rotate. S3: When the screw (83) rotates, it drives one set of vertical racks (84) to rise and the other set of vertical racks (84) to fall. When the vertical racks (84) move, they drive the connecting gear (86) to rotate. When the connecting gear (86) rotates, it drives one of the two helical racks (87) to move obliquely upward and the other obliquely downward. When the helical racks (87) move, they drive the connecting block (88) to slide on the connecting rod (89). At the same time, they drive the secondary grippers (9) to move synchronously. The two secondary grippers (9) move obliquely upward and downward, and form a misalignment to facilitate the unloading of the brass rod.
