Description

Technical Field

[0001] The invention relates to the technical field of turnover and blanking manipulators, and in particular to a turnover and blanking manipulator for powder metallurgy parts. Background Art

[0002] Powder metallurgy is a process for producing metal materials, composite materials and various types of products by using metal powder or a mixture of metal powder and non-metallic powder as raw materials through forming and sintering. After the powder is made into powder metallurgy parts in the forming machine, a push rod is usually used to push the powder metallurgy parts to a conveyor belt, which then transports the powder metallurgy parts away.

[0003] Some existing powder metallurgy parts have raised structures. In the sintering process after molding, they need to be stacked on the bracket. The raised structure must be located at the top. However, during molding in the molding machine, the raised structure is at the bottom. Therefore, workers must flip the blanks on the conveyor belt and stack them on the bracket. On the one hand, the push rod is prone to bumping and colliding when pushing the powder metallurgy parts away from the molding machine, and the powder metallurgy parts are prone to cracking before sintering, resulting in waste. On the other hand, manual flipping of powder metallurgy parts is also prone to falling and bumping other powder metallurgy parts, resulting in chipped corners of the powder metallurgy parts and waste. When a robot is used to flip and unload the parts, vibration often occurs when the telescopic parts are started. Long-term vibration can easily cause the robot to loosen, which is not conducive to clamping. At the same time, the shapes and sizes of the parts are different, and different clamping methods and angles should be used for clamping. In addition, when the parts are placed on the conveyor belt surface, they are prone to sliding due to inertia, causing collisions between parts. To avoid the above situation, we have proposed a powder metallurgy parts flipping and unloading robot. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a powder metallurgy parts turning and unloading robot, comprising a bottom plate, a frame fixedly connected to the top of the bottom plate, a top plate fixedly connected to the top of the frame, a unloading mechanism provided inside the frame, and a conveying mechanism provided at the interval between the unloading mechanism and the bottom plate;

[0005] A material discharge mechanism is provided inside the frame, the material discharge mechanism has a slide, both ends of the slide are slidably connected to the inner wall of the frame, the side of the slide away from the top plate is fixedly connected to the box, the inner wall of the box is penetrated by a connecting arm, the outer surface of the connecting arm is slidably connected to the inner wall of the box, and the number of the connecting arms is symmetrically provided with two, a first telescopic rod is provided at the interval between the two connecting arms, and the first telescopic rod is fixedly connected to the outer surface of the box;

[0006] Also includes:

[0007] CCD detector, which is arranged at the interval between the two connecting arms, and the CCD detector is fixedly connected to the end of the first telescopic rod away from the box body, and the CCD detector is used to detect the grasping, flipping angle and placement of the parts. The CCD detector takes pictures and compares the parts grasped by the blanking mechanism, so as to adjust the grasping position through the blanking mechanism, and similarly adjust the flipping angle and the putting down position to avoid slipping caused by poor grasping position, bumping caused by too much or too little flipping angle, and falling of parts caused by uncertain putting down position, thereby avoiding damage to parts and producing waste. At the same time, other parts on the two connecting arms cooperate with each other to grasp the two parts separately. The CCD detector is arranged at the interval between them, and can detect the two parts on both sides, thereby reducing the manufacturing cost of the flipping and blanking manipulator;

[0008] A control panel is fixedly connected to one side of the frame, the output end of the control panel is electrically connected to the blanking mechanism, and the control panel controls the flipping and blanking operation of the blanking mechanism. The input end of the control panel is electrically connected to the CCD detector, and the control panel controls the blanking mechanism to grab parts, flip parts, and put down parts.

[0009] Furthermore, the control panel includes a signal receiving module, a signal processing module, a storage module and a control module. The output end of the signal receiving module is electrically connected to the input end of the signal processing module, the output end of the signal processing module is electrically connected to the input end of the control module, the storage module is electrically connected to the control module, the signal receiving module is used to receive the electrical signal transmitted from the CCD detector to the inside of the control panel, the signal processing module is used to convert and process the electrical signal received inside the signal receiving module, the control module is used to compare the signal inside the signal processing module with the signal inside the storage module, and control the flipping and unloading operation of the unloading mechanism, the storage module is used to store the position information of grabbing, flipping and placing multiple groups of parts, and provide it to the control module for comparison, and the control module can control the signal processing module The signal inside the block is compared with any set of position information, and the control panel controls the unloading mechanism to grab, flip and place the parts. At the same time, the first telescopic rod follows the grabbing, flipping and placement of a part, and performs shooting detection before the time node of the next operation, records the final situation of the part being grabbed, flipped and placed, and transmits the detected three sets of position information to the signal receiving module in the control panel. The signal receiving module passes the received three sets of position information to the signal processing module for conversion and processing, and then controls the processed signal through the control module to compare with the three sets of position information set inside the storage module. When the processed signal matches the position information set inside the storage module, the control module controls the unloading mechanism to stop adjusting the grabbing position, stop flipping, and stop adjusting the placement position.

[0010] Furthermore, the unloading mechanism also includes a longitudinal robotic arm, which is rotatably connected to the end of the connecting arm away from the box body through a rotating rod, and the end of the longitudinal robotic arm away from the connecting arm is rotatably connected to a transverse robotic arm through a rotating rod, and the end of the transverse robotic arm away from the longitudinal robotic arm is fixedly connected to a circumferential rotating seat, and a ball is limited and rotated on the inner wall of the circumferential rotating seat, and the side of the ball away from the circumferential rotating seat is rotatably connected to a mechanical claw through a rotating rod. The longitudinal robotic arm, the transverse robotic arm, the circumferential rotating seat and the mechanical claw are all driven by a driver. The longitudinal robotic arm rotates around the connecting arm to adjust the vertical gripping angle, and the transverse robotic arm rotates around the longitudinal robotic arm to adjust the horizontal gripping angle, and cooperates with the clamping of the mechanical claw to achieve multi-angle clamping of the part. The formed part needs to be flipped. When flipping, the part is inside the mold. If you want to take it out, you need to find a suitable angle so that it will not slip and fall and cause waste. At the same time, the two different transverse robotic arms rotate to adjust the spacing between the two mechanical claws to be the same as the spacing between the parts, thereby achieving flipping and unloading of the two parts.

[0011] Furthermore, a telescopic platform is fixedly connected to the side of the slide away from the box body, and the side of the telescopic platform away from the slide is fixedly connected to the side of the top plate close to the frame body. The telescopic platform is extended and retracted to drive the slide to rise and fall, thereby adjusting the height between the parts and the conveying mechanism to avoid the parts being placed too high, causing the assembly to collide, thereby avoiding the collision caused by the collision and causing waste parts.

[0012] Furthermore, a sliding rod is symmetrically provided at the corners of the slide, the sliding rod is fixedly connected to a side of the slide close to the telescopic platform, and one end of the sliding rod away from the slide passes through the top plate, and the outer surface of the sliding rod is slidably connected to the inner wall of the top plate, the outer sleeve of the sliding rod is provided with a shock-absorbing spring, and the two ends of the shock-absorbing spring are respectively fixedly connected to the side where the top plate and the slide are close to each other, and a limit plate is symmetrically provided inside the frame body, and the limit plate is fixedly connected to the inner wall of the frame body, and the limit plate is provided on the side of the slide away from the top plate. The slide is raised and lowered, driving the sliding rod to slide on the inner wall of the top plate, thereby playing a limiting role, avoiding the long-term use of the slide, causing stagnation and vibration during sliding, and avoiding affecting the stability of the parts placement position. At the same time, the shock-absorbing spring further performs buffering to achieve a shock-absorbing effect, further ensuring the stability of the placement position.

[0013] Furthermore, rubber blocks are symmetrically arranged on the side where the mechanical claws are close to each other, and the rubber blocks are arranged on the side of the mechanical claws away from the ball. The rubber blocks are fixedly connected to the outer surface of the end of the mechanical claws, and the rubber blocks are arranged in a semi-cylindrical shape. When the mechanical claws clamp smaller parts, the smaller parts have higher precision, resulting in lower pressure they can withstand. The rubber blocks can increase the friction with the parts without changing the clamping force of the mechanical claws, thereby avoiding slipping of the parts due to insufficient clamping force during movement and flipping, and further avoiding waste parts.

[0014] Furthermore, an arc-shaped plate is provided inside the mechanical claw, and the two ends of the arc-shaped plate are respectively fixedly connected to the side where the two claws of the mechanical claw are close to each other, and an arc-shaped groove is provided on the outer surface of the arc-shaped plate. When the mechanical claw clamps a larger part, the larger part has a larger volume and needs to be clamped into the interior of the mechanical claw. The two claws of the mechanical claw approach each other, driving the arc-shaped plate to deform. The arc-shaped plate deforms and presses the part against and fixes it on the side not clamped by the mechanical claw, and the other side of the part presses against the surface of the rubber block. The cylindrical rubber block limits the other side of the part, thereby further preventing the part from slipping and causing waste parts. At the same time, the arc-shaped groove can make the arc-shaped plate easier to deform, thereby achieving abutment and fixation of the part, and when abutting against the part, the abutting position is also more likely to be concave, fitting the shape of the part, achieving wrapping of the part, and preventing special-shaped parts from being damaged by being squeezed by the arc-shaped plate, thereby further avoiding waste parts.

[0015] The cam is connected to the second link by a spring, and the two ends of the cam are connected to each other with a spring, and the two ends of the cam are connected with each other with a spring, and the two ends of the cam are connected with each other with a spring, and the two ends of the cam are connected with each other with a spring. Drive the sleeve plate to move, thereby driving another second telescopic rod to move synchronously, the second telescopic rod moves, drives the connecting arm to move, drives the longitudinal mechanical arm to move, drives the transverse mechanical arm to move, drives the circumferential rotating seat to move, drives the ball to move, drives the mechanical claw to move, and the two mechanical claws synchronously reach the predetermined optimal clamping position, and then drive the two mechanical claws to clamp the part, thereby saving the cost of a second telescopic rod. When the second telescopic rod is started, vibration is inevitable. The vibration of the second telescopic rod will drive other parts to vibrate, which may easily cause the connecting parts of the parts to loosen, resulting in the mechanical claw being unable to accurately clamp the parts. The second telescopic rod vibrates when it starts, driving the mounting seat to move irregularly, and the mounting seat rotates around the sliding column and rubs to consume the vibration in this direction. The mounting seat moves, driving the sliding column to move inside the sleeve, thereby driving the buffer spring to deform, further consuming the vibration, and avoiding vibration-induced loosening of the parts of this device to ensure the clamping effect of the mechanical claw.

[0016] Furthermore, the conveying mechanism includes a motor, the outer surface of the motor is fixedly connected to a fixing frame, and the side of the fixing frame away from the motor is fixedly connected to the outer surface of the frame, the end of the motor is fixedly connected to a driving shaft, and the end of the driving shaft away from the motor is rotatably connected to the frame, the outer surface of the driving shaft is fixedly connected to a driving roller, the outer surface of the driving roller is sleeved with a transmission belt, the inner wall of the transmission belt is transmission-connected to a driven roller, and the driven roller is arranged on the side of the frame away from the driving roller, the inner wall of the driven roller is fixedly connected to a driven shaft, and the two ends of the driven shaft are respectively rotatably connected to the frame, the outer surface of the transmission belt is provided with a V-shaped groove, and a plurality of V-shaped grooves are evenly provided on the surface of the transmission belt, and the direction of the V-shaped grooves In the opposite direction of the conveyor belt's movement, the mechanical claw grabs the part, flips the direction and places it in the middle of the conveyor belt surface. The conveyor belt drives the part to move until it reaches the subsequent processing. By opening a V-shaped groove, the friction on the conveyor belt surface is increased, thereby preventing the part from sliding on the conveyor belt surface due to inertia, avoiding affecting the spacing between multiple parts, and even collisions between parts, avoiding scrap caused by collisions between parts. At the same time, the direction of the V-shaped groove is opposite to the movement direction of the conveyor belt. When the part is placed in the middle of the conveyor belt, the part rests on both sides of the V-shaped groove and is subjected to pressure from the part. The symmetrical sides of the V-shaped groove can provide symmetrical reaction forces to the part, thereby maintaining the position of the part and preventing the part from deflecting, thereby ensuring the stability of the part's position on the conveyor belt.

[0017] Furthermore, an H-frame is fixedly connected to the side of the bottom plate close to the frame body, and a baffle is fixedly connected to the side of the H-frame away from the bottom plate, and the H-frame is provided with several members at the interval between the bottom plate and the baffle, and both sides of the baffle are inclined toward the side away from each other, and the baffle does not contact the conveyor belt. By setting the baffle, the parts can be shielded when the parts are placed incorrectly to prevent the parts from falling off the conveyor belt, causing the parts to fall and cause waste parts. The two sides of the baffle are inclined toward the side away from each other, which can increase the protection range and further prevent parts from falling and causing waste parts. At the same time, the baffle does not contact the conveyor belt, thereby avoiding friction between the inner wall of the conveyor belt and the baffle, thereby reducing power loss and achieving the purpose of saving energy.

[0018] The present invention has the beneficial effects:

[0019] 1. The present invention sets a CCD detector, which takes pictures and compares the parts grasped by the blanking mechanism, so that the grasping position is adjusted by the blanking mechanism. Similarly, the flipping angle and the lowering position are adjusted to avoid slipping caused by poor grasping position, bumping caused by too much or too little flipping angle, and falling of parts caused by uncertain lowering position, thereby avoiding damage to parts and generating waste. At the same time, other parts on the two connecting arms cooperate with each other to grasp the two parts separately. The CCD detector is set at the interval between them, which can detect the two parts on both sides, reducing the manufacturing cost of the flipping and blanking robot.

[0020] 2. The present invention sets a blanking mechanism. The longitudinal robotic arm rotates around the connecting arm to adjust the vertical grasping angle. The transverse robotic arm rotates around the longitudinal robotic arm to adjust the horizontal grasping angle. Cooperating with the clamping of the mechanical claws, multi-angle clamping of the parts is achieved. The formed parts need to be flipped. When flipping, the parts are located inside the mold. If you want to take them out, you need to find a suitable angle to prevent them from slipping and falling and causing waste. At the same time, the two different transverse robotic arms rotate to adjust the distance between the two mechanical claws to the same as the distance between the parts, thereby achieving flipping and blanking of the two parts.

[0021] 3. The present invention provides a mechanical claw. When the mechanical claw clamps smaller parts, the smaller parts have higher precision, resulting in lower pressure that the parts can withstand. The rubber block can increase the friction with the parts without changing the clamping force of the mechanical claw, thereby preventing the parts from slipping during movement and flipping due to insufficient holding force, further avoiding waste. When the mechanical claw clamps larger parts, the larger parts have a larger volume and need to be clamped inside the mechanical claw. The two claws of the mechanical claw approach each other, causing the arc plate to deform. The arc plate deforms and presses the part against the side not clamped by the mechanical claw, thereby fixing it. The other side of the part abuts against the surface of the rubber block. The cylindrical rubber block limits the other side of the part, thereby further preventing the part from slipping and avoiding waste. At the same time, the arc groove can make the arc plate easier to deform, thereby achieving abutment and fixation of the part. When abutting against the part, the abutting position is also more likely to be concave, fitting the shape of the part, achieving wrapping of the part, and preventing special-shaped parts from being damaged by the arc plate, thereby further avoiding waste.

[0022] 4. The present invention sets a sleeve plate, and a second telescopic rod is extended and retracted to drive the sleeve plate to move, thereby driving the other second telescopic rod to move synchronously, and the two mechanical claws reach the predetermined optimal clamping position synchronously, thereby saving the cost of a second telescopic rod. When the second telescopic rod is started, it will inevitably vibrate. The vibration of the second telescopic rod will drive other parts to vibrate, which may easily cause the connecting parts of the parts to loosen, thereby causing the mechanical claws to be unable to accurately clamp the parts.

[0023] 5. The present invention increases the friction force on the surface of the conveyor belt by arranging V-shaped grooves, thereby preventing parts from sliding on the surface of the conveyor belt due to inertia, avoiding affecting the spacing between multiple parts, and even colliding between parts, avoiding scrap caused by collisions between parts. At the same time, the direction of the V-shaped groove is opposite to the movement direction of the conveyor belt. When the parts are placed in the middle of the conveyor belt, the parts rest against both sides of the V-shaped groove and are subjected to pressure from the parts. Therefore, the symmetrical sides of the V-shaped groove can provide symmetrical reaction forces to the parts, thereby maintaining the position of the parts and preventing the parts from deflecting, thereby ensuring the stability of the parts' placement on the conveyor belt.

[0035] Example 1

[0036] See also Figures 1-9 The present invention is a powder metallurgy parts turning and unloading robot, comprising a bottom plate 1, a frame 2 fixedly connected to the top of the bottom plate 1, a top plate 3 fixedly connected to the top of the frame 2, a unloading mechanism 4 provided inside the frame 2, and a conveying mechanism 5 provided at the interval between the unloading mechanism 4 and the bottom plate 1;

[0037] The unloading mechanism 4 is arranged inside the frame 2 and has a slide 41. Both ends of the slide 41 are slidably connected to the inner wall of the frame 2. The side of the slide 41 away from the top plate 3 is fixedly connected to the box 43. The inner wall of the box 43 is penetrated by a connecting arm 44. The outer surface of the connecting arm 44 is slidably connected to the inner wall of the box 43. There are two connecting arms 44 symmetrically provided. A first telescopic rod 410 is provided at the interval between the two connecting arms 44, and the first telescopic rod 410 is fixedly connected to the outer surface of the box 43.

[0038] Also includes:

[0039] The CCD detector 6 is arranged at the interval between the two connecting arms 44, and the CCD detector 6 is fixedly connected to the end of the first telescopic rod 410 away from the box 43. The CCD detector 6 is used to detect the grasping, flipping angle and placement of the parts. The CCD detector 6 takes pictures and compares the parts grasped by the blanking mechanism 4, so as to adjust the grasping position through the blanking mechanism 4. Similarly, the flipping angle and the lowering position are adjusted to avoid slipping caused by poor grasping position, bumping caused by too much or too little flipping angle, and falling of parts caused by uncertain lowering position, thereby avoiding damage to parts and producing waste. At the same time, other parts on the two connecting arms 44 cooperate with each other to grasp the two parts separately. The CCD detector 6 is arranged at the interval between them and can detect the two parts on both sides, thereby reducing the manufacturing cost of the flipping and blanking manipulator;

[0040] The control panel 7 is fixedly connected to one side of the frame 2. The output end of the control panel 7 is electrically connected to the blanking mechanism 4. The control panel 7 controls the flipping and blanking operation of the blanking mechanism 4. The input end of the control panel 7 is electrically connected to the CCD detector 6.

The signal receiving module transmits the received three sets of position information to the signal processing module for conversion and processing, and then controls the processed signal through the control module to compare with the three sets of position information set in the storage module. When the processed signal matches the position information set in the storage module, the control module controls the unloading mechanism 4 to stop adjusting the grabbing position, stop flipping, and stop adjusting the placement position.

[0042] Example 2

[0043] See also Figures 1-6The unloading mechanism 4 also includes a longitudinal robotic arm 45, which is rotatably connected to the end of the connecting arm 44 away from the box 43 through a rotating rod. The end of the longitudinal robotic arm 45 away from the connecting arm 44 is rotatably connected to a transverse robotic arm 46 through a rotating rod. The end of the transverse robotic arm 46 away from the longitudinal robotic arm 45 is fixedly connected to a circumferential rotating seat 47. The inner wall of the circumferential rotating seat 47 is limited and rotated with a ball 48. The side of the ball 48 away from the circumferential rotating seat 47 is rotatably connected to a mechanical claw 49 through a rotating rod. The longitudinal robotic arm 45, the transverse robotic arm 46, the circumferential rotating seat 47 and the mechanical claw 49 are all driven by a driver. The robotic arm 45 rotates around the connecting arm 44 to adjust the vertical gripping angle. The transverse robotic arm 46 rotates around the longitudinal robotic arm 45 to adjust the horizontal gripping angle. Cooperating with the clamping of the mechanical claw 49, multi-angle clamping of the parts is achieved. The formed parts need to be flipped. When flipping, the parts are located inside the mold. If you want to take them out, you need to find a suitable angle to prevent them from slipping and falling and causing waste. At the same time, the two different transverse robotic arms 46 rotate to adjust the spacing between the two mechanical claws 49 to the same as the spacing between the parts, thereby achieving flipping and unloading of the two parts.

[0044] The side of the slide 41 away from the box body 43 is fixedly connected to the telescopic platform 42, and the side of the telescopic platform 42 away from the slide 41 is fixedly connected to the side of the top plate 3 close to the frame body 2. The telescopic platform 42 is extended and retracted to drive the slide 41 to rise and fall, thereby adjusting the height between the parts and the conveying mechanism 5 to avoid the parts being placed too high, causing the assembly to collide, thereby avoiding the collision caused by the collision and causing waste parts.

[0045] The sliding rod 420 is symmetrically provided at the corner of the slide plate 41, and the sliding rod 420 is fixedly connected to the side of the slide plate 41 close to the telescopic platform 42, and the end of the sliding rod 420 away from the slide plate 41 passes through the top plate 3, and the outer surface of the sliding rod 420 is slidably connected to the inner wall of the top plate 3. The outer sleeve of the sliding rod 420 is provided with a shock-absorbing spring 421, and the two ends of the shock-absorbing spring 421 are respectively fixedly connected to the side where the top plate 3 and the slide plate 41 are close to each other. The inner part of the frame body 2 is symmetrically provided with a limit plate 422, and the limit plate 422 is fixedly connected to the inner wall of the frame body 2. The limit plate 422 is set on the side of the slide plate 41 away from the top plate 3. The slide plate 41 is raised and lowered, driving the sliding rod 420 to slide on the inner wall of the top plate 3, thereby playing a limiting role, avoiding the slide plate 41 from being used for a long time, causing stagnation and vibration during sliding, and avoiding affecting the stability of the parts placement position. At the same time, the shock-absorbing spring 421 further buffers to achieve a shock-absorbing effect, further ensuring the stability of the placement position.

[0046] Rubber blocks 417 are symmetrically arranged on the side where the mechanical claws 49 are close to each other, and the rubber block 417 is arranged on the side of the mechanical claw 49 away from the ball 48. The rubber block 417 is fixedly connected to the outer surface of the end of the mechanical claw 49, and the rubber block 417 is arranged in a semi-cylindrical shape. When the mechanical claw 49 clamps smaller parts, the smaller parts have higher precision, resulting in lower pressure they can withstand. The rubber block 417 can increase the friction with the parts without changing the clamping force of the mechanical claw 49, thereby avoiding slipping of the parts due to insufficient holding force during movement and flipping, and further avoiding waste parts.

[0047] The interior of the mechanical claw 49 is provided with an arc plate 418, and the two ends of the arc plate 418 are fixedly connected to the side where the two claws of the mechanical claw 49 are close to each other, and the outer surface of the arc plate 418 is provided with an arc groove 419. When the mechanical claw 49 clamps a larger part, the larger part has a larger volume and needs to be clamped into the interior of the mechanical claw 49. The two claws of the mechanical claw 49 approach each other, driving the arc plate 418 to deform, and the arc plate 418 deforms to press the part against the mechanical claw 49, so that the part can be clamped when the mechanical claw 49 is not clamped. The other side of the part abuts against the surface of the rubber block 417. The cylindrical rubber block 417 limits the other side of the part, thereby further preventing the part from slipping and causing waste. At the same time, the arc groove 419 can make the arc plate 418 more easily deformed, thereby achieving the abutment and fixation of the part, and when abutting against the part, the abutting position is also more likely to be concave, fitting the shape of the part, achieving the wrapping of the part, and preventing the special-shaped parts from being squeezed by the arc plate 418 and causing damage, thereby further avoiding waste.

[0048] One end of the two connecting arms 44 located inside the box body 43 is fixedly connected to the second telescopic rod 411, and only one of the second telescopic rods 411 is driven by the main force, and the other second telescopic rod 411 only has a telescopic function. The end of the second telescopic rod 411 away from the connecting arm 44 is fixedly connected to the inner wall of the box body 43, and a sleeve plate 412 is provided on the side of the second telescopic rod 411 close to the connecting arm 44, and the inner wall of the sleeve plate 412 is fixedly connected to the outer surface of the two second telescopic rods 411 respectively, and the sleeve plate 412 is fixedly connected to the mounting seat 413 on the side away from the connecting arm 44. The side of the mounting seat 413 away from the sleeve 412 is rotatably connected to the sliding post 414 through a rotating rod. The side of the sliding post 414 away from the mounting seat 413 is provided with a sleeve 415. The side of the sleeve 415 away from the sliding post 414 is fixedly connected to the inner wall of the box body 43, and the outer surface of the sliding post 414 is slidably connected to the inner wall of the sleeve 415. A buffer spring 416 is provided inside the sleeve 415, and the two ends of the buffer spring 416 are respectively fixedly connected to the bottom of the inner wall of the sleeve 415 and the end of the sliding post 414 located inside the sleeve 415. A second telescopic rod 411 is extended The second telescopic rod 411 moves synchronously, and the second telescopic rod 411 moves, which drives the connecting arm 44 to move, drives the longitudinal mechanical arm 45 to move, drives the transverse mechanical arm 46 to move, drives the circumferential rotating seat 47 to move, drives the ball 48 to move, drives the mechanical claw 49 to move, and the two mechanical claws 49 synchronously reach the predetermined optimal clamping position, and then drive the two mechanical claws 49 to clamp the parts, thereby saving the cost of a second telescopic rod 411. When the second telescopic rod 411 is started, it is inevitable that vibration will occur. The vibration of the second telescopic rod 411 will cause other parts to vibrate, which may easily cause the connecting parts of the parts to loosen, thereby causing the mechanical claw 49 to be unable to accurately clamp the parts. The second telescopic rod 411 vibrates when it starts, causing the mounting seat 413 to move irregularly. The mounting seat 413 rotates around the sliding column 414 and rubs to consume the vibration in this direction. The mounting seat 413 moves, driving the sliding column 414 to move inside the sleeve 415, thereby driving the buffer spring 416 to deform, further consuming the vibration, and avoiding the parts of the device from loosening due to vibration, so as to ensure the clamping effect of the mechanical claw 49.

[0049] Example 3

[0050] See also Figure 7-Figure 8The conveying mechanism 5 includes a motor 51, the outer surface of the motor 51 is fixedly connected to a fixing frame 52, and the side of the fixing frame 52 away from the motor 51 is fixedly connected to the outer surface of the frame 2, the end of the motor 51 is fixedly connected to a driving shaft 53, and the end of the driving shaft 53 away from the motor 51 is rotatably connected to the frame 2, the outer surface of the driving shaft 53 is fixedly connected to a driving roller 54, the outer surface of the driving roller 54 is sleeved with a transmission belt 55, the inner wall of the transmission belt 55 is transmission-connected with a driven roller 56, and the driven roller 56 is arranged on the side of the frame 2 away from the driving roller 54, the inner wall of the driven roller 56 is fixedly connected to a driven shaft 57, and the two ends of the driven shaft 57 are respectively rotatably connected to the frame 2, the outer surface of the transmission belt 55 is provided with a V-shaped groove 510, and a plurality of V-shaped grooves 510 are evenly provided on the surface of the transmission belt 55, and the direction of the V-shaped grooves 510 is consistent with the transmission belt 55. The movement direction of the conveyor belt 55 is opposite. The mechanical claw 49 grabs the part, flips the direction and places it in the middle of the surface of the conveyor belt 55. The conveyor belt 55 drives the part to move until it reaches the subsequent processing. By opening the V-shaped groove 510, the friction on the surface of the conveyor belt 55 is increased, thereby preventing the parts from sliding on the surface of the conveyor belt 55 due to inertia, avoiding affecting the spacing between multiple parts, and even collisions between parts, avoiding collisions between parts and causing waste. At the same time, the direction of the V-shaped groove 510 is opposite to the movement direction of the conveyor belt 55. When the part is placed in the middle of the conveyor belt 55, the part rests on both sides of the V-shaped groove 510 and is subjected to the pressure of the part. Therefore, the symmetrical sides of the V-shaped groove 510 can provide symmetrical reaction forces to the part, thereby maintaining the position of the part and preventing the part from deflecting, thereby ensuring the stability of the part's placement on the conveyor belt 55.

[0051] An H-frame 58 is fixedly connected to the side of the base plate 1 close to the frame body 2, and a baffle 59 is fixedly connected to the side of the H-frame 58 away from the base plate 1, and several H-frames 58 are provided at the interval between the base plate 1 and the baffle 59. The two sides of the baffle 59 are inclined to the side away from each other, and the baffle 59 does not contact the conveyor belt 55. By setting the baffle 59, the parts can be blocked when the parts are placed incorrectly to prevent the parts from detaching from the conveyor belt 55, causing the parts to fall and cause waste parts. The two sides of the baffle 59 are inclined to the side away from each other, which can increase the protection range and further prevent parts from falling and causing waste parts. At the same time, the baffle 59 does not contact the conveyor belt 55, thereby avoiding friction between the inner wall of the conveyor belt 55 and the baffle 59, thereby reducing power loss and achieving the purpose of saving energy.

[0052] During use, the control panel 7 controls the blanking mechanism 4 to grab, flip and place the parts. At the same time, the first telescopic rod 410 follows the grabbing, flipping and placement of a part, and performs shooting detection before the time node of the next operation, records the final situation of the part being grabbed, flipped and placed, and transmits the three sets of position information detected to the signal receiving module in the control panel 7. The signal receiving module transmits the received three sets of position information to the signal processing module for conversion processing, and then controls the processed signal through the control module to compare with the three sets of position information set in the storage module. When the processed signal matches the position information set in the storage module, the control module controls the blanking mechanism 4 to stop adjusting the grabbing position, stop flipping, and stop adjusting the placement position.

[0053] During the flipping and unloading process, the telescopic platform 42 is extended and retracted, driving the slide plate 41 to rise and fall, thereby adjusting the height between the part and the conveying mechanism 5. The two different transverse mechanical arms 46 rotate to adjust the spacing between the two mechanical claws 49 to the same spacing as the parts. A second telescopic rod 411 is extended and retracted, driving the sleeve plate 412 to move, thereby driving the other second telescopic rod 411 to move synchronously. The second telescopic rod 411 moves, driving the connecting arm 44 to move, driving the longitudinal mechanical arm 45 to move, driving the transverse mechanical arm 46 to move, driving the circumferential rotating seat 47 to move, driving the ball 48 to move, and driving the mechanical claw 49 to move. The two mechanical claws 49 synchronously reach the predetermined optimal clamping position, and then drive the two mechanical claws 49 to clamp the part. At the same time, the first telescopic rod 410 is extended and retracted following the part, so that the CCD detector 6 always maintains a relatively stationary movement with the clamped part. Subsequently, under the control of the control panel 7, the ball 48 rotates inside the circumferential rotating seat 47, and the mechanical claw 49 also rotates, completing the flipping process. Finally, under the control of the control panel 7, the part is stably placed on the surface of the conveyor belt 55.

[0054] During part transmission, the mechanical claw 49 grabs the part, flips it and places it in the middle of the surface of the conveyor belt 55. The conveyor belt 55 drives the part to move until it reaches the subsequent processing.
