DETAILED DESCRIPTION

[0022] ​Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Referring to Figures 1 to 5 The present embodiment provides a laser cleaning device, which comprises a laser cleaning device 10, and a storage mechanism is arranged on one side of the laser cleaning device. The storage mechanism comprises a storage bin 201, and a feeding port 206 and a discharging port 205 are arranged on the storage bin 201 respectively. A conveying part for conveying materials 208 is symmetrically arranged in the storage bin 201. Adjustment parts are symmetrically arranged on both sides of the storage bin 201 close to the feeding port 206. A material collecting mechanism is arranged on the outer side of the storage bin 201 close to the discharging port 205. The material collecting mechanism comprises slide rails 501 symmetrically arranged on the outer side of the storage bin 201. A sliding seat 502 is slidably connected to the slide rails 501. A lifting mechanism is fixedly connected to the sliding seat 502. A cleaning seat 701 is fixedly connected to the top surface of the lifting mechanism. A limiting mechanism is fixedly connected to the cleaning seat 701.

[0025] The adjustment parts arranged on the conveying part close to the feeding port 206 can align the postures of the materials 208 and reduce the falling impact of the materials 208. The slide rails, the lifting mechanism and the limiting mechanism can realize accurate receiving and flexible fixing of the materials 208. The angle adjustment mechanism can ensure the laser irradiation angle. The present application can realize the collaborative operation of the storage, material pushing, material collecting and fixing links, and improve the overall efficiency.

[0026] Further optimization scheme, the storage bin 201 is fixedly connected with a layer plate 204, the conveying part comprises a conveying belt 202 installed below the layer plate 204, the conveying belt 202 is provided with partition plates 203 at equal intervals, a partition groove 207 is formed between adjacent two partition plates 203, the partition groove 207 is used for placing the materials 208, and the adjustment part is located below the conveying belt 202. Since the present application adopts the integrated design of storage and material pushing, the conveying belt 202 with the partition plates 203 is arranged in the storage bin 201, so that each material 208 is independently contained in the partition groove 207, thereby fundamentally avoiding the stacking and mutual interference of the materials in the storage bin and eliminating the material jamming phenomenon caused by the disordered arrangement of the materials in the traditional separate storage and material pushing mechanism.

[0027] The layer plate 204 is located in the middle of the storage bin 201, and divides the storage bin 201 into two layers, the conveying belt 202 is arranged in the x direction, and the material 208 is stored in the storage bin 201 in the y direction. The conveying belt 202 is located in the lower layer of the storage bin 201, and the partition plate 203 is provided with a plurality of partition plates 203, and the plurality of partition plates 203 are respectively connected to the conveying belt 202 of the conveying belt 202. A plurality of grooves 207 are formed on the conveying belt 202, and each groove 207 can place the material 208. The top surface of one side of the storage bin 201 is provided with a feeding port 206, and the side surface of the other side of the storage bin 201 is provided with a discharging port 205. One end of the conveying belt 202 abuts against the discharging port 205, so that when the conveying belt 202 is driven, the material 208 abutting against the discharging port 205 can be pushed from the groove 207 on the conveying belt 202 to the discharging port 205. At the same time, the next groove 207 pushes the material 208 to the position abutting against the discharging port 205.

[0028] The conveying belt 202 comprises the following mechanisms:

[0029] The driving unit

[0030] The driving unit comprises a servo motor (power is adapted to the weight of the material 208, such as 0.5-1.5kW), a planetary reducer and a shaft coupling. The output shaft of the servo motor is connected to the input end of the reducer through the shaft coupling, and the output end of the reducer is connected to the driving sprocket. By controlling the motor speed, the speed of the conveying belt 202 can be adjusted (such as 0.1-0.5m / s), and the pushing rhythm of different materials 208 can be adapted.

[0031] The conveying belt 202 body

[0032] A double-row roller chain (the chain type is selected according to the weight of the material 208, such as 16A or 20A) is adopted, and the two rows of chains are arranged in parallel and at intervals (the interval is slightly smaller than the length of the material 208, so that the material 208 can be pushed by the partition plate 203 on the chain at both ends). The chain pitch is uniform (such as 25.4mm), which ensures smooth transmission.

[0033] The partition plate 203 assembly

[0034] The partition plate 203 is a rectangular metal plate (made of 45 steel, with a thickness of 3-5mm), which is vertically welded or fixed on the chain links of the two rows of chains (one partition plate 203 is installed every 3-5 chain links, and the interval distance is slightly larger than the diameter of the material 208, forming an independent groove 207). The height of the partition plate 203 is 50-100mm (higher than the diameter of the material 208 by 1 / 2, to prevent the material 208 from falling during transmission), and the edges of the partition plate 203 are rounded (to avoid scratching the material 208).

[0035] The support and guide unit

[0036] It includes a rack, a guide rail and a driven sprocket. The rack is a profile steel welded structure (such as angle steel or square steel), which is fixed to the bottom surface of the lower layer of the storage bin 201 and is used to bear the entire conveying belt 202 mechanism; the guide rail is a wear-resistant steel plate (such as Q235), which is laid under the two rows of chains and is in contact with the chain rollers, plays a supporting and guiding role, and prevents the chains from sagging due to bearing; the driven sprocket is installed at the end of the rack away from the driving unit, is the same height as the driving sprocket, is fixed through a bearing seat, and ensures that the chain remains horizontal when transmitting.

[0037] Tensioning device

[0038] A screw adjusting type tensioning structure is adopted and is installed at the bearing seat of the driven sprocket. The bearing seat is moved along the length direction (x direction) of the rack by rotating the screw to adjust the tension of the chain (to avoid transmission slip or jam caused by relaxation), and the tensioning amount can be visually adjusted through the scale mark.

[0039] Auxiliary assembly

[0040] Limit detection unit

[0041] An optical sensor (such as a diffuse reflection type photoelectric switch) is installed on the rack near the discharge port 205 and is used to detect whether the baffle 203 with the material 208 reaches the position of the discharge port 205. When the sensor detects the material 208, a feedback signal is fed back to the control system to trigger the conveying belt 202 to slow down or temporarily stop, so as to ensure that the material 208 is accurately pushed into the discharge port 205.

[0042] Protection assembly

[0043] A dustproof shield (made of aluminum alloy or plastic) is additionally installed on the outside of the chain to prevent dust and debris in the storage bin 201 from entering the meshing part of the chain; an observation window (transparent acrylic plate) is provided on the shield to facilitate observation of the internal transmission state.

[0044] Working principle of the conveying belt 202

[0045] The servo motor drives the driving sprocket to rotate through the reducer, drives the double-row roller chain to transmit along the x direction, and the baffle 203 on the chain moves synchronously with the chain. When the material 208 falls into the gap 207 (between two adjacent baffles 203), the baffle 203 pushes the material 208 to move along the chain towards the discharge port 205; when the material 208 is pushed to abut against the discharge port 205, the baffle 203 continues to move and pushes the material 208 from the gap 207 into the discharge port 205; at the same time, the subsequent baffle 203 drives the next material 208 to enter the pushing position, realizing continuous and orderly transmission of the material 208.

[0046] The conveying belt 202 can be a chain type conveying belt 202, so that the baffles 203 can be conveniently installed.

[0047] The further optimization scheme adjusting part includes the bottom plate 403 arranged on both sides in the storage bin 201, the bottom plate 403 is located below the feeding port 206, the outer side of the bottom plate 403 is fixedly connected with the alignment plate 301, the bottom surface of the bottom plate is fixedly connected with the buffer spring 401 in a symmetrical mode, the oil damper 402 is arranged between the two buffer springs 401, the oil damper 402 is fixedly connected with the bottom surface of the bottom plate 403, and the bottom of the oil damper 402 is fixedly connected with the bottom surface of the storage bin 201. Since the alignment mechanism and the slow descending mechanism are innovatively integrated, the alignment plate 301 forcibly guides and aligns the falling material; meanwhile, the buffer spring 401 in the slow descending mechanism provides initial buffering, and in particular, the oil damper 402 changes the falling of the material from free fall to uniform slow descending through the throttling action of the piston damping hole, so that the material can stably fall into the trough of the conveying belt in a correct and consistent posture, and the pain points of the traditional equipment, such as disordered material and easy damage, are solved.

[0048] The alignment plate 301 has an included angle of less than 90 degrees with the layer plate 204, the alignment plate 301 is arranged at both ends of the storage bin 201, when the material 208 falls into the trough 207 after entering the feeding port 206, the two ends of the material 208 are in contact with and slide on the alignment plate 301, and when the material 208 falls to the alignment plate 301 opposite to the feeding port 206, the material 208 is aligned.

[0049] The two buffer springs 401 are installed at the bottom of the bottom plate 403 and connected to the lower bottom surface of the storage bin 201, the height of the bottom plate 403 is arranged at the feeding port 206 through the buffer spring 401, the layer plate 204 is provided with an opening for the buffer spring 401 and the bottom plate 403 to pass through, when the buffer spring 401 bears the material 208, the weight of the material 208 can compress the buffer spring 401 to the lower layer of the storage bin 201, so that the bottom plate 403 is flush with or lower than the height of the layer plate 204. The oil damper 402 is connected to the bottom of the bottom plate 403 and also connected to the bottom surface of the storage bin 201. The conveying belt 202 also includes two, which are arranged at both ends of the storage bin 201 and used for pushing the two ends of the material 208. The material 208 is placed on the bottom plate 403, and the material 208 slowly falls into the trough 207 through the oil damper 402.

[0050] The oil damper 402 is a single-rod hydraulic damping structure, mainly including a cylinder body, a piston rod, a piston, oil, a sealing assembly and a connecting part, and is in a columnar shape, which is suitable for the installation space (the length is designed according to the slow descending stroke, and is usually 100-150 mm) of the lower layer of the storage bin 201.

[0051] Cylinder: Made of seamless steel pipe (material 45 steel), the inside is a cylindrical cavity, the cavity is filled with hydraulic oil (such as anti-wear hydraulic oil L-HM46, suitable for -10~60℃ working environment), the bottom of the cylinder is provided with a mounting flange, which is fixed on the bottom surface of the lower layer of the storage bin 201 by bolts.

[0052] Piston rod: solid steel rod (diameter 10-15mm), the top end is connected to the bottom of the bottom plate 403 through a ball hinge (the ball hinge design can adapt to the slight inclination of the bottom plate 403, avoiding the force bias of the piston rod), and the lower part of the rod body extends into the cavity of the cylinder and is rigidly connected with the piston (such as welding or threaded fastening).

[0053] Piston: a circular metal disc (diameter slightly smaller than the inner diameter of the cylinder, gap ≤0.1mm), coaxially fixed with the piston rod, 3-4 damping holes (hole diameter 1-2mm) are evenly arranged on the circumference of the piston, and a one-way valve plate (composed of a spring and a valve flap) is arranged in the hole. The one-way valve plate only allows the oil to flow from the upper chamber (close to the top end of the piston rod) to the lower chamber (close to the bottom of the cylinder) to open, and closes when flowing in the opposite direction.

[0054] When the material 208 is placed on the bottom plate 403, the gravity of the material 208 overcomes the spring force, pushes the bottom plate 403 to move downward, at this time the piston rod moves downward synchronously with the bottom plate 403, and drives the piston to compress the oil in the cylinder:

[0055] When the piston moves downward, the oil in the upper chamber flows into the lower chamber through the damping hole on the piston. Because the diameter of the damping hole is small, the oil flow generates resistance, forming damping force to slow down the downward speed of the piston;

[0056] The one-way valve plate is in a closed state at this time (it opens when the oil flows from the lower chamber to the upper chamber), which ensures that the damping force stably acts on the piston, avoiding the rapid falling of the bottom plate 403;

[0057] When the material 208 is pushed away from the bottom plate 403 by the conveyor belt 202 mechanism, the spring force resets, pushes the bottom plate 403 to move upward, at this time the piston moves upward, the oil in the lower chamber pushes open the one-way valve plate to flow into the upper chamber (the resistance is very small when the one-way valve opens), which ensures that the bottom plate 403 quickly rises to the initial position (below the feeding port 206) and waits for the next placement of the material 208.

[0058] The track is arranged on one side of the storage bin 201 and corresponds to the discharge port 205. The track is arranged along the x direction. The lifting mechanism is installed on the track and can move to a cleaning position in the x direction along the track. The laser cleaning equipment 10 is arranged at a position opposite to the cleaning position. The lifting mechanism can be lifted. The limiting mechanism is installed on the lifting mechanism. The sliding seat is movably connected with the sliding rail. The track includes two tracks which are arranged at intervals.

[0059] The sliding seat includes:

[0060] Slide body

[0061] Welded with Q23 steel plate (thickness 8-10mm), rectangular frame structure (length 300-400mm, width 150-200mm, height 100-150mm), top welded horizontal mounting plate (roughness Ra3.2), used for fixing the lifting seat mechanism by bolts; bottom reserved wheel set installation slot, axle bracket welded in the slot (steel plate bending piece, thickness 10mm).

[0062] Rolling wheel assembly

[0063] There are 4 groups of rolling wheels (2 groups on the front side and 2 groups on the back side, symmetrically arranged along the x direction), each group including a wheel body, an axle, a deep groove ball bearing and a bearing seat.

[0064] Wheel body: polyurethane coated wheel (outer layer polyurethane hardness 85 Shore A, inner layer steel core thickness 5mm), diameter 80-100mm, width 30-40mm, with wear resistance (service life ≥50,000 hours) and shock absorption (reducing vibration when moving); V-shaped groove (groove angle 90°) is set in the middle of the wheel surface, which cooperates with the V-shaped top surface of the slide rail (to prevent lateral deviation of the slide).

[0065] Axle: 45 steel quenching and tempering treatment (diameter 20-25mm), fixed on the axle bracket of the slide body through the bearing seat (cast iron material) at both ends, connected between the axle and the wheel body through the deep groove ball bearing (model 6205), ensuring flexible rotation of the wheel body (rotation resistance ≤3N).

[0066] Lateral guide wheel assembly

[0067] To limit the deviation of the slide along the y direction, 2 groups of lateral guide wheels (4 groups in total) are arranged on both sides of the slide body.

[0068] Guide wheel: nylon material (wear-resistant and quiet), diameter 30-40mm, wheel surface is a plane, which is in contact with the side surface of the slide rail (vertical to the x direction), gap ≤0.5mm.

[0069] Mounting structure: the guide wheel is fixed on the side bracket of the slide body through a short shaft (diameter 10mm), and the short shaft can adjust the gap between the guide wheel and the side surface of the slide rail through eccentric bolts (to ensure close contact but no jamming).

[0070] Drive connection assembly

[0071] The middle part of the sliding base body is welded with a driving connecting plate (steel plate with thickness of 12 mm), a waist-shaped hole is formed in the plate (adapted to the connecting position of different driving mechanisms), and the plate is fixed with the connecting piece of the driving chain / synchronous belt through bolts. If the chain drive is adopted, the connecting piece is a chain joint (hinged with a chain pin shaft); if the synchronous belt drive is adopted, the connecting piece is a synchronous belt clamping plate (clamping the synchronous belt body), and the driving force is transmitted to the sliding base through the connecting plate to drive the sliding base to move along the x direction.

[0072] Further optimization scheme, the lifting mechanism includes a lifting motor 601 symmetrically fixed on the top surface of the sliding base, a lifting bearing seat 602 is fixed on the driving end of the lifting motor 601, and a cleaning seat 701 is fixed on the lifting bearing seat 602.

[0073] The driving end of the lifting motor 601 is connected with the lifting bearing seat 602, which is used to drive the lifting bearing seat 602 to move up and down.

[0074] Further optimization scheme, the two sides of the cleaning seat 701 are respectively provided with two side grooves, the lifting pieces 702 are fixed in the side grooves, the top of the lifting piece 702 is fixed with a U-shaped frame 703, the U-shaped frame 703 is slidably connected with the side groove, the opening of the U-shaped frame 703 faces the discharge port 205, and the opening side of the U-shaped frame 703 is provided with a closing part.

[0075] The cleaning seat 701 is arranged along the y direction, the two ends of the cleaning seat 701 are respectively connected to the two lifting bearing seats 602, and the cleaning seat 701 is used to carry the material 208.

[0076] Further optimization scheme, the closing part includes a driving motor 707 fixed on the top surface of the U-shaped frame 703, a gear set is in transmission connection with the output shaft of the driving motor 707, a closing plate 706 is hinged on the top of the opening of the U-shaped frame 703, and the closing plate 706 is in transmission connection with the gear set.

[0077] Further optimization scheme, the opening bottom of the U-shaped frame 703 is fixed with an extension piece 705.

[0078] The lifting member 702 is installed at the bottom of the cleaning seat 701, and is lifted up and down by the side slot on the cleaning seat 701, and can be lifted above the cleaning seat 701. The U-shaped frame 703 is connected to the lifting member 702, the side slot is matched with the U-shaped frame 703, the U-shaped frame 703 can be threaded in the side slot, and the U-shaped frame 703 can be lifted above the side slot and can be retracted into the side slot. The opening of the U-shaped frame 703 faces the discharge port 205, and the heights are matched. The closure is connected to the outside of the side wall above the U-shaped frame 703, and the closure includes a driving motor 707, a driving gear set, and a closure plate 706, the closure plate 706 is hinged to the side wall on the upper side of the U-shaped frame 703, the driving motor 707 drives the closure plate 706 to rotate the U-shaped frame 703 through the driving gear set, and the hinge shaft of the closure plate 706 is arranged in the y direction. The extension member 705 is installed on the bottom side wall of the U-shaped frame 703 and extends outward from the opening of the U-shaped frame 703.

[0079] When the material 208 is discharged from the discharge port 205, the sliding seat drives the structure installed thereon to move to the material receiving position corresponding to the discharge port 205 in advance, the lifting member 702 is lifted, and the height of the U-shaped frame 703 is adjusted to correspond to the discharge port 205. At this time, the extension member 705 abuts against the discharge port 205. After the material 208 is discharged, it enters the extension member 705 and finally enters the U-shaped frame 703. The closure plate 706 is driven by the driving motor 707 to rotate towards the inside of the U-shaped frame 703, and abuts against both sides of the material 208. Then, the lifting member 702 moves downward, and the U-shaped frame 703 is retracted into the side slot, so that the upper side of the material 208 is abutted against the upper side wall of the U-shaped frame 703, and the bottom of the material 208 is abutted against the cleaning seat 701, forming a fixation of the material 208.

[0080] Further optimization scheme, the lifting bearing seat 602 is provided with an angle adjusting mechanism, the lifting bearing seat 602 is provided with a groove 804, the angle adjusting mechanism includes a bottom member 803 fixedly connected to the bottom plate of the cleaning seat 701, two sides of the bottom member 803 are symmetrically fixedly connected with a lateral spring 801, the lateral spring 801 abuts against the inner wall of the groove 804, and the side of the lifting bearing seat 602 away from the discharge port 205 is provided with a lateral motor 802, the output shaft of the lateral motor 802 extends into the groove 804 and is fixedly connected with the bottom member 803.

[0081] The lifting carrier 602 has a groove 804, the bottom member 803 is installed at the bottom of the cleaning seat 701 and extends into the groove 804 of the lifting carrier 602, the lateral spring 801 is installed on the two side walls of the bottom member 803 and is connected to the inner wall of the groove 804 respectively, and the lateral motor 802 is connected to the side of the lifting carrier 602 away from the discharge port 205 and the driving end penetrates into the groove 804 and is connected to the side of the bottom member 803 away from the discharge port 205. At the same time, the lateral motor 802 includes one, which is installed on the side of one lifting carrier 602 close to the laser cleaning equipment 10. For the other lifting carrier 602 away from the laser cleaning equipment 10, no lateral motor 802 is arranged. For the other lifting carrier 602 away from the laser cleaning equipment 10, the cleaning seat 701 and the lifting carrier 602 are provided with a vertical rotating shaft, which rotatably connects the lifting carrier 602 and the cleaning seat 701 in the middle of the end away from the laser cleaning equipment 10. For the end of the cleaning seat 701 close to the laser cleaning equipment 10, it is previously deviated by 10-30 degrees away from the discharge port 205, and the lateral motor 802 abuts against the bottom member 803 at the bottom of the cleaning seat 701. In this way, only one lateral motor 802 needs to be arranged to complete the angle calibration of the material 208 in the horizontal direction after being installed on the cleaning seat 701. At the same time, the arrangement of one lateral motor 802 does not interfere with other structures. Laser ranging sensors and the like are arranged at the corresponding positions of the cleaning seat 701 for measuring the angle of the material 208.

[0082] Working principle

[0083] The material 208 is poured from the feeding port 206 at the top surface of the storage bin 201, and contacts the alignment plate 301 at both ends of the storage bin 201 during falling, and is aligned in the x direction by sliding (both ends are attached to the alignment plate 301), so as to realize preliminary posture calibration.

[0084] The calibrated material 208 falls on the bottom plate 403 below the feeding port 206, the bottom plate 403 is compressed under the gravity of the material 208, and the oil damper 402 changes the falling of the material 208 from free fall to uniform and slow descent through the throttling effect of the piston damping hole, so that the material 208 falls stably into the partition groove 207 of the lower conveying belt 202, avoiding surface damage or posture skew caused by impact.

[0085] The transmission belt 202 starts, and the partition plate 203 of the transmission belt 202 drives the material 208 in the partition groove 207 to move along the x direction. When the material 208 is pushed to the position abutting against the discharge port 205, the transmission belt 202 continues to drive, pushes the material 208 from the partition groove 207 into the discharge port 205 and discharges it; at the same time, the material 208 in the next partition groove 207 is moved to the position abutting against the discharge port 205 along with the transmission belt 202, and waits for the next pushing, which fundamentally avoids the stacking and mutual interference of the materials in the storage bin, and realizes the continuous, non-stuck and orderly pushing of the materials.

[0086] The sliding seat of the material receiving and fixing integrated mechanism moves along the track to the position corresponding to the discharge port 205, the lifting mechanism drives the cleaning seat 701 to lift, the opening of the U-shaped frame of the limiting mechanism is aligned with the height of the discharge port 205, at this time, the extension piece 705 abuts against the discharge port 205, forming a transition channel for the transmission of the material 208.

[0087] After the material 208 is discharged from the discharge port 205, it slides into the U-shaped frame through the extension piece 705. The driving motor 707 of the closing mechanism drives the closing plate 706 to rotate towards the inside of the U-shaped frame through the driving gear set, and abuts against the material 208 from both sides; then the lifting piece 702 drives the U-shaped frame 703 to shrink into the side groove of the cleaning seat 701, so that the upper side of the material 208 is pressed tightly by the upper side wall of the U-shaped frame 703, and the bottom is abutted with the cleaning seat 701, realizing the stable fixing of the materials 208 with different sizes and shapes.

[0088] The laser ranging sensor detects the current angle of the material 208, and feeds back a signal to the angle adjusting mechanism: the lateral motor 802 close to the laser cleaning equipment 10 starts, pushes the bottom component 803 at the bottom of the cleaning seat 701, so that the cleaning seat 701 rotates around the pivot away from the laser end as the fulcrum, and the lateral spring 801 buffers the rotation process to avoid impact; through the adjustment, the angle of the material 208 is calibrated to the best position of the vertical irradiation of the laser.

[0089] After the angle is calibrated, the sliding seat drives the cleaning seat 701 and the fixed material 208 to move to the cleaning position along the track, and the laser cleaning equipment 10 starts to clean the cavity wall of the material 208; after the cleaning is completed, each mechanism is reset, and the next cycle is prepared.

[0090] The conveying belt 202 continuously pushes the stack-avoiding, eliminates the risk of material jam caused by the separation of storage and pushing, and improves the continuity of feeding. The adjusting part forces the material 208 to align along the x direction through the inclined plate, ensures the uniformity of the posture, reduces the falling impact through the buffer spring 401 and oil damping, avoids surface damage, prevents the material 208 from being skewed again, and provides a basis for subsequent positioning. The U-shaped frame 703 and the closed plate 706 can adapt to different sizes and shapes of the material 208, the lifting and shrinking design realizes multi-direction clamping, and solves the problem of poor adaptability of the traditional mechanism. The unilateral motor driving + angle adjustment structure of the shaft support point can accurately calibrate the angle of the material 208, ensure that the laser vertically irradiates the cavity wall, and improve the uniformity of cleaning.
