Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts production, and in particular relates to a conveying system for a lightweight production line of automobile parts. Background Art

[0002] Automobile lightweighting is a complete concept, which means that the weight of the automobile is reduced in a targeted manner while maintaining the original performance of driving safety, crash resistance, shock resistance and comfort, and without increasing the cost of the automobile itself, so as to improve the power of the automobile, reduce fuel consumption and reduce exhaust pollution.

[0003] At present, lightweight production lines for automotive parts are used in most automotive parts production plants. Conveyor belts are generally configured on the production lines to transport parts. In the existing technology, the following problems exist in the transportation of parts:

[0004] 1. Due to the light weight of parts, lightweight parts are easily moved due to human error or external machine interference during transportation on the conveyor belt, resulting in the problem of part position deviation;

[0005] 2. When the conveyor belt accelerates or decelerates, lighter parts are prone to rolling on the conveyor belt due to inertia, resulting in improper placement, which is not conducive to subsequent processing operations. In the existing technology, most of the parts are manually straightened by staff, which is complicated and inefficient. Some parts are straightened by robots, which has the problem of high operating and maintenance costs.

[0006] 3. Due to the poor environment in the processing workshop, there will inevitably be dust, water stains and other stains on the conveyor belt. When parts deviate or roll on the conveyor belt, their surface will be contaminated with dust and water stains, causing pollution. If they are not cleaned, the product quality will be reduced. Summary of the Invention

[0007] The purpose of the present invention is to provide a conveying system for a lightweight production line of automotive parts to address the problems of low efficiency in straightening parts after deviation or rolling and easy staining of their surfaces raised in the above background technology.

[0008] To achieve the above-mentioned object, the present invention adopts the following technical solutions: a conveying system for a lightweight production line of automobile parts, comprising a workbench, a support frame fixedly connected to the workbench, a hydraulic cylinder fixedly mounted on the support frame, a C-shaped plate fixed to the output end of the hydraulic cylinder, two side plates fixed to the workbench, a conveyor belt provided between the two side plates, a camera assembly for monitoring the position of parts mounted on the C-shaped plate, a turning mechanism for straightening the parts disposed at the lower end of the C-shaped plate, and a cleaning mechanism for removing dust from the surface of the parts disposed on the side walls of the C-shaped plate;

[0009] The flip mechanism includes two sleeves fixedly connected to the lower end of the C-shaped plate, a flip rod is rotatably connected in the sleeve, a positioning assembly is provided on the end of the flip rod close to the conveyor belt, and a ratchet is fixed on the end of the flip rod away from the conveyor belt. A vertically arranged fixing plate is fixedly connected to the side wall of the support frame, and ratchet teeth are provided on the surface of the fixing plate to match the ratchet;

[0010] The cleaning mechanism includes an air collecting box rotatably connected to a C-shaped plate, a plurality of exhaust pipes are connected to the circumferential side walls of the air collecting box, and the plurality of exhaust pipes all adopt an L-shaped structure and are arranged in a circular array. A pressure valve is installed at the connection between the exhaust pipe and the air collecting box, and two sliding rods are slidably connected through the side walls of the air collecting box. A cleaning brush is fixed to one end of the sliding rod located outside the air collecting box, and a positioning plate is fixed to one end of the sliding rod located inside the air collecting box, and the positioning plate is connected to the inner wall of the air collecting box by a first spring;

[0011] An air supply assembly is fixed on the side wall of the C-shaped plate, and the air supply assembly is used to input air into the air collecting box. When the air pressure in the air collecting box reaches the critical value of the pressure valve, the air is discharged from the exhaust pipe to clean the parts.

[0012] Furthermore, the positioning assembly includes a positioning plate fixedly connected to the flip rod, an electric telescopic rod is installed on the side wall of the positioning plate, and an output end of the electric telescopic rod is connected to a pressure plate.

[0013] Furthermore, a groove is provided in the pressing plate, a shielding box is fixed in the groove, the shielding box is provided with an opening on one side close to the conveyor belt, and a spiral coil is provided in the shielding box.

[0014] Furthermore, a self-locking switch is installed on the side panel, and the spiral coil is connected in parallel with the electric telescopic rod through conduction, and is electrically connected to the power supply through the self-locking switch.

[0015] Furthermore, the air supply assembly includes a sealing cylinder fixedly connected to the side wall of the C-shaped plate, the output end of the sealing cylinder is connected to the air collecting box through a connecting pipe, and a one-way valve is installed at the connection between the connecting pipe and the sealing cylinder, and a piston plate is sealingly and slidingly fitted in the sealing cylinder, and the piston plate is connected to the inner wall of the sealing cylinder through a second spring.

[0016] Furthermore, the air supply assembly also includes an electromagnet fixedly connected to the inner bottom surface of the sealing cylinder, the side of the piston plate close to the electromagnet is made of magnetic material, and the piston plate and the electromagnet have the same poles facing each other.

[0017] Furthermore, a conductive block is fixedly connected to the side wall of the flip rod, and a power connection plate is fixedly connected to the inner wall of the sleeve. Both the conductive block and the power connection plate adopt an arc structure. The conductive block is electrically connected to an external power supply, and the power connection plate is electrically connected to the electromagnet. When the conductive block and the power connection plate are in contact, the electromagnet is energized.

[0018] Furthermore, damping rings are fixed at the openings at both ends of the sleeve, and the damping rings are rotatably sleeved on the flip rod.

[0019] Furthermore, the output end direction of the exhaust pipe is parallel to the tangential direction of the gas collecting box, and the angle between the output end direction of the exhaust pipe and the horizontal plane is 45°.

[0020] The present invention has the following advantages:

[0021] 1. The present invention is provided with a positioning assembly and a self-locking switch. When the parts on the conveyor belt deviate from the working position, the hydraulic cylinder drives the C-shaped plate to move downward, so that the two sets of positioning assemblies are located on both sides of the parts. At this time, the sleeve contacts the self-locking switch, automatically controlling the electric telescopic rod to open, pushing the two pressure plates closer to each other, pushing the parts to straighten, and avoiding affecting subsequent processing.

[0022] 2. The present invention sets a flipping mechanism. After the two pressure plates press and straighten the parts, the hydraulic cylinder drives the C-shaped plate to move up, and drives the ratchet to rotate through the ratchet teeth, thereby flipping the parts. Since the parts move up synchronously with the C-shaped plate, they will not collide or interfere with the conveyor belt during flipping. After the parts are flipped to face the front side upward, the hydraulic cylinder drives the C-shaped plate downward again. In this direction, the ratchet does not rotate, and the parts can be put flat on the conveyor belt again, and the straightening and flipping reset of the parts can be achieved synchronously. Compared with the manual straightening and robot operation methods in the prior art, the work efficiency is improved and the operation and maintenance costs are reduced.

[0023] 3. The present invention sets an air supply assembly and uses the flip rod as the driving force to drive the conductive block to rotate in the sleeve, so that the conductive block is in intermittent contact with the power plate, thereby realizing intermittent power supply to the electromagnet. During the flipping process of the parts, air is continuously filled into the air collecting box through the sealing cylinder, so that the various mechanisms cooperate closely and operate in a coordinated and synchronous manner.

[0024] 4. The present invention is provided with a cleaning mechanism. When the air pressure in the air collecting box reaches the critical value of the pressure valve, the air is discharged from the exhaust pipe and blown obliquely downward to the surface of the component, so as to blow away the dust and water stains attached to the surface. As the component is turned over, all surfaces of the component are fully cleaned.

[0025] Moreover, under the reaction force of the airflow, the air collecting box is pushed to rotate, and then the surface of the parts is cleaned by the cleaning brush, further improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] like Figure 1-6As shown, a conveying system for a lightweight production line of automotive parts includes a workbench 1, a support frame 2 is fixedly connected to the workbench 1, a hydraulic cylinder 3 is fixedly installed on the support frame 2, a C-shaped plate 4 is fixed to the output end of the hydraulic cylinder 3, two side plates 5 are fixed on the workbench 1, a conveyor belt 6 is arranged between the two side plates 5, and a camera component 7 for monitoring the position of parts is installed on the C-shaped plate 4. The camera component 7 adopts a monitoring camera, which can monitor and shoot the parts on the conveyor belt 6 in real time. The monitoring camera is connected to the hydraulic cylinder 3 through a controller via an electrical signal. When the part is offset or flipped, the hydraulic cylinder 3 can be controlled to start running. The monitoring camera and the controller are both existing technologies in this field and are not described in detail here. The lower end of the C-shaped plate 4 is provided with a flipping mechanism 8 for straightening the part, and the side wall of the C-shaped plate 4 is provided with a cleaning mechanism 9 for removing dust from the surface of the part.

[0034] The flip mechanism 8 includes two sleeves 10 fixedly connected to the lower end of the C-shaped plate 4, a flip rod 11 is rotatably connected in the sleeve 10, a positioning assembly 12 is provided at the end of the flip rod 11 close to the conveyor belt 6, a ratchet 13 is fixed at the end of the flip rod 11 away from the conveyor belt 6, a vertically arranged fixed plate 14 is fixedly connected to the side wall of the support frame 2, and a ratchet 15 matching the ratchet 13 is provided on the surface of the fixed plate 14. When the hydraulic cylinder 3 drives the C-shaped plate 4 to move downward, the flip rod 11 is driven to move downward synchronously through the sleeve 10. In this direction , the ratchet 13 does not rotate. When the hydraulic cylinder 3 drives the C-shaped plate 4 to move upward, in this direction, the ratchet 15 engages with the ratchet 13, so that the ratchet 13 rotates synchronously during the upward movement. Since the parts move upward synchronously with the C-shaped plate 4, they will not collide or interfere with the conveyor belt 6 when flipping. After the parts are flipped to the front side facing up, the hydraulic cylinder 3 drives the C-shaped plate 4 to move downward and place the parts on the conveyor belt 6 again. Compared with the manual straightening and robot operation methods in the prior art, this improves work efficiency and reduces operation and maintenance costs.

[0035] The cleaning mechanism 9 includes an air collecting box 16 rotatably connected to the C-shaped plate 4, and a plurality of exhaust pipes 17 are connected to the circumferential side walls of the air collecting box 16. The plurality of exhaust pipes 17 all adopt an L-shaped structure and are arranged in a circular array. A pressure valve is installed at the connection between the exhaust pipe 17 and the air collecting box 16. The output end direction of the exhaust pipe 17 is parallel to the tangential direction of the air collecting box 16, and the output end direction of the exhaust pipe 17 is at an angle of 45° to the horizontal plane. Two sliding rods 18 are slidably connected through the side wall of the air collecting box 16, and a cleaning brush 19 is fixed to one end of the sliding rod 18 located outside the air collecting box 16, and a positioning plate 20 is fixed to one end of the sliding rod 18 located inside the air collecting box 16. The positioning plate 20 is connected to the inner wall of the air collecting box 16 through a first spring 21;

[0036] When the air pressure in the air collecting box 16 reaches the critical value of the pressure valve, the air is discharged from the exhaust pipe 17 and blown obliquely downward to the surface of the component, so as to blow away the dust and water stains attached to the surface. As the component flips, all surfaces of the component are fully cleaned. Moreover, under the reaction force of the airflow, the air collecting box 16 is pushed to rotate, and then the surface of the component is cleaned by the cleaning brush 19, further improving the cleaning effect.

[0037] An air supply assembly 22 is fixed on the side wall of the C-shaped plate 4. The air supply assembly 22 is used to input air into the air collecting box 16. When the air pressure in the air collecting box 16 reaches the critical value of the pressure valve, the air is discharged from the exhaust pipe 17 to clean the parts.

[0038] The positioning assembly 12 includes a positioning plate 20 fixedly connected to the flip rod 11, an electric telescopic rod 23 is installed on the side wall of the positioning plate 20, and the output end of the electric telescopic rod 23 is connected to a pressure plate 24;

[0039] A groove is formed in the pressing plate 24, in which a shielding box 25 is fixed. The shielding box 25 is opened on one side close to the conveyor belt 6, and a spiral coil 26 is provided in the shielding box 25.

[0040] A self-locking switch 27 is installed on the side panel 5. The self-locking switch 27 will close after being pressed once, making the circuit conductive, and will be disconnected after being pressed again. This is the existing technology. The spiral coil 26 is connected in parallel with the electric telescopic rod 23 through electrical conductivity, and is electrically connected to the power supply through the self-locking switch 27. When the parts on the conveyor belt 6 deviate from the working position, the hydraulic cylinder 3 drives the C-shaped plate 4 to move downward, so that the two sets of positioning components 12 are located on both sides of the parts. At this time, the sleeve 10 contacts the self-locking switch 27, automatically controlling the electric telescopic rod 23 to open, pushing the two pressure plates 24 closer to each other, pushing the parts to straighten them, and avoiding affecting subsequent processing. When the spiral coil 26 is energized, a magnetic field is generated around it, which can generate magnetic attraction on parts made of iron materials, making the pressure plate 24 clamp the parts more firmly, preventing the parts from falling when flipping. The shielding box 25 makes the magnetic field of the spiral coil 26 more directional, thereby increasing the magnetic attraction force on the parts.

[0041] The air supply assembly 22 includes a sealing cylinder 28 fixedly connected to the side wall of the C-shaped plate 4. The output end of the sealing cylinder 28 is connected to the air collecting box 16 through a connecting pipe 29, and a one-way valve is installed at the connection between the connecting pipe 29 and the sealing cylinder 28. The one-way valve only allows the air in the sealing cylinder 28 to enter the air collecting box 16. The sealing cylinder 28 is sealed and slidingly fitted with a piston plate 30, and the piston plate 30 is connected to the inner wall of the sealing cylinder 28 through a second spring 31.

[0042] The air supply assembly 22 further includes an electromagnet 32 ​​fixedly connected to the inner bottom surface of the sealing cylinder 28 . The side of the piston plate 30 close to the electromagnet 32 ​​is made of magnetic material, and the piston plate 30 and the electromagnet 32 ​​have the same poles facing each other.

[0043] A conductive block 33 is fixedly connected to the side wall of the flip rod 11, and a power connection piece 34 is fixedly connected to the inner wall of the sleeve 10. Both the conductive block 33 and the power connection piece 34 adopt an arc structure. The conductive block 33 is electrically connected to the external power supply, and the power connection piece 34 is electrically connected to the electromagnet 32. When the conductive block 33 contacts the power connection piece 34, the electromagnet 32 ​​is energized. During operation, the flip rod 11 is used as the driving force to drive the conductive block 33 to rotate in the sleeve 10, so that the conductive block 33 and the power connection piece 34 are intermittently in contact, thereby realizing intermittent energization of the electromagnet 32, and then pushing the piston to reciprocate in the sealing cylinder 28. During the flipping process of the parts, air is continuously filled into the air collecting box 16 through the sealing cylinder 28, so that the various mechanisms cooperate closely and operate in a coordinated and synchronous manner.

[0044] Damping rings 35 are fixed at the openings at both ends of the sleeve 10. The damping ring 35 is rotatably sleeved on the flip rod 11. The damping ring 35 is used to increase the friction force of the flip rod 11 rotating in the sleeve 10 to avoid deflection caused by the offset of the center of gravity of the components.

[0045] When the present invention is in use, the parts are transported by the conveyor belt 6. When the part that is offset or flipped moves to the bottom of the camera assembly 7, the conveyor belt 6 stops running, the hydraulic cylinder 3 is started, and the C-shaped plate 4 is driven downward, so that the two sets of positioning assemblies 12 are located on both sides of the part. At this time, the sleeve 10 contacts the self-locking switch 27, automatically controlling the electric telescopic rod 23 to open, pushing the two pressing plates 24 closer to each other, pushing the part to straighten it, avoiding affecting subsequent processing, and pressing and fixing the part;

[0046] After the two pressing plates 24 press and straighten the parts, the hydraulic cylinder 3 drives the C-shaped plate 4 to move upward, and drives the ratchet 13 to rotate through the ratchet 15, thereby flipping the parts. Since the parts move upward synchronously with the C-shaped plate 4, they will not collide with the conveyor belt 6 during flipping. After the camera assembly 7 observes that the parts are flipped to the front side upward, the hydraulic cylinder 3 drives the C-shaped plate 4 to move downward again. In this direction, the ratchet 13 does not rotate. After the sleeve 10 contacts the self-locking switch 27 again, the electric telescopic rod 23 is powered off and reset, and the parts can be put flat on the conveyor belt 6 again, and the straightening and flipping reset of the parts can be achieved synchronously. Compared with the manual straightening and robot operation methods in the prior art, the work efficiency is improved and the operation and maintenance costs are reduced.

[0047] During the rotation of the flip rod 11, the conductive block 33 is driven to rotate in the sleeve 10, so that the conductive block 33 and the power strip 34 are intermittently contacted, thereby achieving intermittent power supply to the electromagnet 32. During the flipping process of the component, air is continuously filled into the air collecting box 16 through the sealing cylinder 28, so that all mechanisms cooperate closely and operate in a coordinated and synchronous manner.

[0048] When the air pressure in the air collecting box 16 reaches the critical value of the pressure valve, the air is discharged from the exhaust pipe 17 and blown obliquely downward to the surface of the component, so as to blow away the dust and water stains attached to the surface. As the component flips, all surfaces of the component are fully cleaned. Moreover, under the reaction force of the airflow, the air collecting box 16 is pushed to rotate, and then the surface of the component is cleaned by the cleaning brush 19, further improving the cleaning effect. Since the air pressure in the air collecting box 16 decreases as the air is gradually discharged, the rotation speed of the air collecting box 16 decreases, and the centrifugal force of the cleaning brush 19 during rotation gradually decreases, and under the elastic force of the first spring 21, it is in a horizontal position, further ensuring that the surface of the component is fully cleaned.
