Description
Technical Field
[0001] The utility model relates to a manipulator, in particular to a side-mounted garbage collection and transportation manipulator. Background Art
[0002] Domestic garbage bin collection and transportation work is done by either sanitation workers manually loading and unloading them onto garbage trucks or by robotic arms gripping them.
[0003] Among them, manual operation has high work intensity, harsh working environment and slow loading and unloading speed.
[0004] The gripping operation of the manipulator is generally performed by a side-mounted garbage collection and transportation vehicle, which is equipped with a garbage collection manipulator to locate, grab, retract, dump and reset the garbage bins in the garbage collection area. For example, a side-mounted compression dump truck disclosed in Chinese patent CN215556298U has a two-finger gripping structure in its gripping part, which cannot adjust the gripping posture according to the posture of the garbage bin for precise gripping, which easily causes damage to the garbage bin.
[0005] In comparison, the utility model can adjust the gripping posture of the gripper according to the placement of the garbage can, achieve precise grasping of the garbage can, and cooperate with the sensor on the end gripper to provide real-time feedback on the force applied, effectively preventing damage to the garbage can. Utility Model Content
[0006] The technical problem to be solved by the utility model is to provide a side-mounted garbage collection and transportation robot, which can adjust the gripping posture of the gripper according to the placement of the garbage can, so as to achieve precise grasping of the garbage can, and cooperate with the sensor on the end gripper to provide real-time feedback on the force applied, so as to effectively prevent the garbage can from being damaged; at the same time, the position adjustment in the lifting and horizontal directions is more convenient and accurate.
[0007] In order to solve the above technical problems, the utility model adopts the following technical means:
[0008] A side-mounted garbage collection and transportation manipulator consists of a grasping mechanism, a lifting mechanism, a lateral position adjustment mechanism, a telescopic mechanism, a visual auxiliary operation mechanism, and a control mechanism.
[0009] The gripping mechanism grabs or releases the bin.
[0010] The grasping mechanism consists of a single-finger gripper, a double-finger gripper, a horn frame, a servo hydraulic connecting rod, a rotating shaft, a rotating shaft bearing one, a fastening bolt, a mechanical sensor, a sensor mounting bracket, a horn frame fixing plate, a gripper rotating shaft, a rotating shaft bearing two, a secondary rotating shaft, a secondary rotating shaft bearing, and a servo hydraulic rod fulcrum two. The grasping mechanism is used to grasp the target trash can.
[0011] The servo hydraulic connecting rod is provided with a primary servo hydraulic connecting rod and a secondary servo hydraulic connecting rod.
[0012] The left and right sides of the grabbing mechanism are respectively a single-finger clamp and a double-finger clamp hinged to the horn rack fixing plate. The single-finger clamp and the double-finger clamp are complementary structures. The single-finger clamp is located in the gap between the double-finger clamp. When clamping the trash can, the trash can can be better fixed to prevent it from falling off and uneven force.
[0013] Both the single-finger clamp and the double-finger clamp are composed of a starting clamp and a terminal clamp. One end of the starting clamp is hingedly connected to the connecting end of the horn frame. A first-level servo hydraulic connecting rod is provided between the starting clamp and the fixing plate of the horn frame. The first-level servo hydraulic connecting rod drives the starting clamp to rotate and adjust the clamping angle; the other end of the starting clamp is hingedly connected to the middle part of the terminal clamp, and the end of the terminal clamp close to the starting clamp is hingedly connected to the two ends of the second-level servo hydraulic connecting rod with the starting clamp respectively. The second-level servo hydraulic connecting rod drives the terminal clamp to rotate around the end of the starting clamp to adjust the clamping angle.
[0014] The first-level servo hydraulic connecting rod rotates around the rotating shaft through the rotating shaft and the rotating shaft bearing 1, and the starting clamping jaw moves through the feeding. The second-level servo hydraulic connecting rod rotates around the second fixed axis of the servo hydraulic rod fulcrum through the second-level rotating shaft and the second-level rotating shaft bearing, and the end clamping jaw moves through the feeding. The servo hydraulic connecting rod realizes the linkage of the starting clamping jaw and the end clamping jaw through the second-level joint push, so that the clamping jaw can adjust the clamping posture according to the placement posture of the trash can, so as to realize the precise grasping of the trash can.
[0015] The starting jaw and the end jaw are driven to adjust the clamping angle through the first-level servo hydraulic connecting rod and the second-level servo hydraulic connecting rod respectively, so that the starting jaw and the end jaw can adjust the clamping angle individually or simultaneously, so that there are more holding postures when clamping, and the holding posture can be adaptively adjusted according to the different placement postures of the trash can.
[0016] The clamping claw at the start end is hingedly connected with the horn frame through the rotating shaft and the rotating shaft bearing 1. The horn frame is fixed on the outer shell of the control mechanism through fastening bolts to ensure the stability of the entire clamping mechanism.
[0017] The mechanical sensor is installed at the sensor mounting bracket at the end of the end gripper. When the end gripper contacts the trash can, the mechanical sensor feedbacks the magnitude of the applied force, senses the surface pressure to indicate the force of the clamping, and senses the surface friction to indicate the degree of clamping. Through the feedback signal, the control mechanism takes the above signal to accurately control the grasping mechanism to respond.
[0018] The lifting mechanism drives the grabbing mechanism and the lateral position adjustment mechanism to lift and lower, and the garbage bin on the grabbing mechanism is turned over and dumped during the lifting process;
[0019] The lateral position adjustment mechanism is used to adjust the position of the grabbing mechanism in the lateral direction, that is, in the direction perpendicular to the lifting direction;
[0020] The telescopic mechanism is connected to the supporting lifting mechanism to drive the supporting lifting mechanism to extend or retract, thereby adjusting its working position;
[0021] A visual auxiliary operation mechanism is arranged at the control mechanism, acquires an image on one side of the grasping mechanism, and transmits the image to the control mechanism;
[0022] The control mechanism is connected and arranged on the lateral position adjustment mechanism, and is provided with a controller for controlling the operation of other components.
[0023] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:
[0024] First: In the horizontal direction, the single-finger gripper of the utility model is located in the gap in the middle of the double-finger gripper, so that the single-finger gripper and the double-finger gripper cooperate with each other to form a three-finger gripping structure. A mechanical sensor is provided on the sensor mounting support of the end gripper to feedback the gripping force and gripping torque of the end, and to control the opening and closing of the gripping mechanism to prevent the trash can from being clamped or falling off during the gripping process.
[0025] Second: By setting the lifting mechanism and the lateral position adjustment mechanism, the height and the clamping position in the horizontal direction can be easily adjusted. By setting the telescopic mechanism, it can be easily extended or retracted, making the lifting or horizontal adjustment more precise.
[0026] As a further improvement to this technical solution:

[0028] The lifting mechanism is driven by an electric motor and has a rapid response. When encountering an emergency, the reaction action can be taken quickly. The lifting drive motor is installed on both sides of the output shaft. The two are connected by a key to realize the driving of the lifting drive motor to the output shaft, so that the output shaft can rotate through the transmission bearing. The rotation of the output shaft drives the rotation of the driving sprocket. The roller chain cooperates with the driving sprocket to achieve rolling. The rolling of the roller chain drives the driven sprocket and the driven shaft to rotate through the transmission bearing. The roller chain is connected to the lateral position adjustment mechanism to drive the lateral position adjustment mechanism to rise and fall. A hydraulic push rod is arranged under the lateral position adjustment mechanism. In the initial stage when the lateral position adjustment mechanism is pulled up, the hydraulic push rod supports and pushes the lateral position adjustment mechanism upward for a distance. In the final stage of the descent of the lateral position adjustment mechanism, the hydraulic push rod supports the hydraulic push rod to retract synchronously and supports the lateral position adjustment mechanism to reset. The hydraulic push rod makes the lateral position adjustment mechanism more balanced in the initial stage and the reset stage of being pulled up, reduces the vibration of the components of the lateral position adjustment mechanism, and improves the stability of the movement. When the roller chain drives the lateral position adjustment mechanism to move to the top of the rib plate and flips to the other side, the lateral position adjustment mechanism also flips accordingly to complete the dumping action.

A small driving motor is arranged at the end of the lateral position adjustment slider module; the transmission shaft on the small driving motor is concentrically matched with the hole of the slider module screw, and the internal thread of the slider is matched with the slider module screw; the small driving motor rotates to drive the slider module screw to rotate, and the rotation of the slider module screw drives the movement of the slider. The circular holes at both ends of the slide are equipped with slide bearings, and the slider module lead screw cooperates with the slide bearings. The compensation function of the module is used to compensate for the position adjustment of the clamping in the lateral direction of the car body to achieve precise clamping. The servo motor is used to control the slider module lead screw transmission, which has smooth control and can effectively reduce the resonance problem of the robot during the compensation process of clamping the trash can along the car body.
[0031] After the dumping is completed, the roller chain reverses and drives the slide to reset. When the slide reaches the starting position of the flip, the hydraulic push rod and the roller chain drive the slide down at the same speed and direction.

[0081] The first-level servo hydraulic connecting rod 1041 rotates around the rotating shaft 105 through the rotating shaft 105 and the rotating shaft bearing 1 106, and the starting clamp 1001 is moved by feeding. The second-level servo hydraulic connecting rod 1042 rotates around the servo hydraulic rod fulcrum 2 115 through the second-level rotating shaft 113 and the second-level rotating shaft bearing 114, and the end clamp 1002 is moved by feeding. The servo hydraulic connecting rod 104 realizes the linkage of the starting clamp 1001 and the end clamp 1002 through the second-level joint push, so that the clamp can adjust the clamping posture of the clamp according to the placement posture of the trash can, thereby realizing accurate grasping of the trash can.
[0082] The starting clamp 1001 and the ending clamp 1002 are driven to adjust the clamping angle by the primary servo hydraulic connecting rod 1041 and the secondary servo hydraulic connecting rod 1042 respectively, so that the starting clamp 1001 and the ending clamp 1002 can adjust the clamping angle individually or simultaneously, so that there are more holding postures when clamping, and the holding posture can be adaptively adjusted according to the different placement postures of the trash can.
[0083] The starting clamping jaw 1001 is hingedly connected to the horn frame 103 through the rotating shaft 105 and the rotating shaft bearing 106.

[0084] The mechanical sensor 108 is installed at the position of the sensor mounting bracket 109 at the end of the end clamp 1002. When the end clamp 1002 contacts the trash can, the mechanical sensor 108 feedbacks the size of the force applied, senses the surface pressure to indicate the clamping force, and senses the surface friction to indicate the degree of clamping. Through the feedback signal, the control mechanism 600 adopts the above signal to accurately control the grasping mechanism 100 to respond.

[0086] Specifically, the roller chain 201 is connected to the driving sprocket 203 and the driven sprocket 204.

The output shaft 206 and the driven shaft 207 cooperate with the transmission bearing 208. The transmission bearing 208 is located in the bearing hole of the rib plate 209. The rib plate 209 is located on both sides of the sprocket and is symmetrical about the sprocket. There is a maximum lifting displacement limit on the rib plate 209, which limits the tipping displacement, prevents the garbage can and the grabbing mechanism from colliding with the vehicle body during the whole process, and prevents the grabbing mechanism from leaving the lifting track.
[0087] The lifting mechanism 200 is driven by a motor and has a quick response. When encountering an emergency, a response action can be taken quickly.

The two are connected by a key to realize the driving of the lifting drive motor 205 on the output shaft 206, so that the output shaft 206 can rotate through the transmission bearing 208. The rotation of the output shaft 206 drives the rotation of the driving sprocket 203. The roller chain 201 cooperates with the driving sprocket 203 to achieve rolling. The rolling of the roller chain 201 drives the driven sprocket 204 to rotate with the driven shaft 207 through the transmission bearing 208.

The hydraulic push rod 202 makes the force of the lateral position adjustment mechanism 300 in the initial stage and the reset stage when it is pulled up more balanced, reduces the vibration of the components of the lateral position adjustment mechanism 300, and improves the stability of the movement.

The circular holes at both ends of the slide 309 are equipped with slide bearings 310, and the slider module screw 308 cooperates with the slide bearing 310. The compensation function of the module is utilized to compensate for the position adjustment of the clamping in the lateral direction of the vehicle body to achieve precise clamping.

[0100] The working process of the side-mounted garbage collection and transportation manipulator of the utility model is as follows:
[0101] Step 1
[0102] First, the driver of the vehicle parks the vehicle within the working range of the manipulator through the image information fed back by the visual auxiliary operation mechanism 500. The camera 513 will locate the center of the trash can and feed back the coordinate information of the trash can to the central controller 602 of the control mechanism 600. After processing the feedback signal, the central controller 602 calculates the gripping center of the gripping mechanism 100 and the distance from the center of the trash can in the direction perpendicular to the ground, and calculates the angle that the motor should rotate through the distance parameter combined with the specific working parameters of the lifting drive motor 205. The movement of the lifting drive motor 205 drives the output shaft 206 to rotate, the output shaft 206 drives the driving sprocket 203 to rotate, the driving sprocket 203 drives the roller chain 201 to move, the roller chain 201 drives the driven sprocket 204 to move, and the driven sprocket 204 drives the driven shaft 207 to move, so that the entire sprocket moves. Through the image feedback of the visual-assisted operating mechanism 500, the lateral position adjustment mechanism 300 connected to the roller chain 201 pin moves. The movement of the lateral position adjustment mechanism 300 drives the control mechanism 600 fixed on the I-shaped sliding shaft 301 at the rear part of the control mechanism housing 601 to move, and drives the grasping mechanism 100 connected to the control housing 601 to move in a direction perpendicular to the ground. Finally, the grasping center of the grasping mechanism 100 is on the same horizontal plane as the center of the trash can. The central controller 602 calculates the distance between the center of the trash can and the center of the grabbing mechanism 100 in the direction of the vehicle body, and drives the lateral position adjustment mechanism 300 to move, thereby compensating for the distance between the center of the trash can and the center of the grabbing mechanism 100 in the direction of the vehicle body. The small drive motor 307 of the lateral position adjustment slider module 304 rotates, driving the slider module lead screw 308 connected to it to rotate. The rotation of the slider module lead screw 308 drives the slider 306 to move, thereby driving the I-shaped sliding shaft 301 connected to the slider 306 to move horizontally in the slide groove of the slideway 302, driving the control mechanism 600 fixed at the rear on the I-shaped sliding shaft 301 to move, and then driving the grabbing mechanism 100 connected to the control housing 601 to move in a direction parallel to the ground. Finally, the grabbing center of the grabbing mechanism 100 and the center of the trash can are in a straight line in a direction perpendicular to the vehicle body.The central controller 602 calculates the distance between the center of the trash can and the center of the grabbing mechanism 100 in the direction perpendicular to the vehicle body, and then drives the telescopic mechanism 400 to move. The driving motor No. 1 414 drives the secondary left lead screw 408 to rotate, and the secondary left lead screw 408 drives the secondary left slider 409 to move. The driving motor No. 2 415 drives the secondary middle lead screw 410 to rotate, and the secondary middle lead screw 410 drives the secondary middle slider 411 to move. The driving motor No. 3 416 drives the secondary right lead screw 412 to rotate, and the secondary right lead screw 412 rotates to drive the secondary right slider 413 to move. The driving motor No. 4 417 drives the primary middle lead screw 420, and the primary middle lead screw 420 drives the inner bracket 421 to move. The motors rotate synchronously at the same time. The sliders of the telescopic mechanism 400 are staggered and connected to the push rod 403, driving the push rod 403 to move close to the trash can. Before approaching the trash can, the central controller 602 controls the pumping out of the hydraulic oil of the servo hydraulic cylinder 604 to shrink the servo hydraulic connecting rod 104 and drive the opening of the clamp. After reaching the grasping position, the central controller 602 controls the servo hydraulic cylinder 604 to pump out the hydraulic oil, so that the servo hydraulic connecting rod 104 is fed forward, thereby clamping the trash can. The mechanical sensor 108 provides real-time feedback on the force applied, and the surface pressure sensed indicates the force of the clamping. The central controller 602 sends a signal to control the servo hydraulic cylinder 604 to pump out the hydraulic oil, change the clamping posture of the clamp, and implement precise clamping.
[0103] Step 2
[0104] After the trash can is grabbed, the motor of the telescopic mechanism 400 drives the lead screw to rotate, thereby driving the grabbing mechanism 100 and the trash can to retract in the opposite direction of the extension direction. Then, the lifting drive motor 205 drives the entire grabbing mechanism 100 and the trash can to rise and then flip to the other side for dumping. The lifting drive motor 205 stops at the dumping position. When the data fed back by the mechanical sensor 108 at the end does not change, it means that the dumping action is completed.
[0105] Step 3
[0106] After the dumping action is completed, the central controller 602 issues a reset command, and the lifting drive motor 205 drives the entire grabbing mechanism 100 and the trash can to descend. When the trash can descends to the same horizontal position as the initial position, the lifting drive motor 205 stops. The telescopic mechanism 400 resets the trash can according to the command at the time of grabbing. After reaching the initial position, the central controller 602 controls the servo hydraulic cylinder 604 to pump out the hydraulic oil and controls the servo hydraulic connecting rod 104 to retract, so that the clamp releases the trash can. The telescopic mechanism 400 retracts, the lateral position adjustment mechanism 300 resets, and the clamp is retracted to a safe position. Finally, the driver on board drives the garbage truck away.
