Description

Technical Field

[0001] The invention relates to a lawn mower blade production device, in particular to a lawn mower blade leveling system. Background Art

[0002] The blade leveling process is an important step in the production process of lawn mower blades. Its purpose is to adjust the flatness of the blade to prevent the blade from hitting the ground during operation, causing damage to the blade and injury to personnel. At present, the blade leveling process is mainly achieved by hammering the blade with a heavy hammer. However, since the bending degree of each blade is different, the position of the hammer hitting the blade is also different. Therefore, it is difficult to meet the manufacturing requirements by using a mechanical hammer to hammer. Most companies still rely on manual operation of the hammer to hit the blade. This not only places high demands on workers, but also slows down the production speed and makes it difficult to ensure uniform production quality. At the same time, the noise generated by the hammering is also very likely to cause occupational diseases among workers. Summary of the invention

[0045] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0046] like Figure 1 As shown, the blade leveling system includes a frame, a conveying device, a clamping device, a leveling device, a visual inspection device, a discharging device, and a controller. The conveying device is used to transport the blade, the clamping device is used to fix the blade on the conveying device, the leveling device is used to adjust the flatness of the blade fixed in the clamping device, the visual inspection device is used to check the flatness of the blade, and the controller is used to control the above mechanisms.

[0047] The frame, conveying device, pressing device, leveling device, visual inspection device, discharging device and controller are all fixed on the frame. The frame includes a first base 31, a second base 32, a support 33, a top frame 34 and a column 35. The first base is fixed to the second base, the two supports are vertically fixed on the first base, the top frame is horizontally fixed on the top of the two supports, and the column is fixed on the second base.

[0048] The conveying device includes a conveyor 1 and a conveyor plate 2. The conveyor is fixed to the first base through a conveyor mounting plate 36. A plurality of conveyor plates 2 are fixed on the bearing surface of the conveyor. A blade is placed on each conveyor plate. The conveyor drives the blade to move horizontally through the conveyor plate ( Figure 3 The arrow in the figure indicates the moving direction). The conveyor is a chain conveyor, which is powered by a conveying motor 1.1 and a reducer 1.2. A conveying plate is fixed on the chain of the chain conveyor. A sensor 22 for detecting the conveying plate is also provided on the side of the chain. The sensor is fixed to the chain conveyor through a sensor mounting plate 23.

[0049] The top surface of the conveying plate is provided with a positioning shaft 2.1, which passes through the center hole of the blade. The top surface of the conveying plate is also provided with stoppers 2.2 symmetrically arranged on both sides of the positioning shaft, and the spacing between the stoppers is suitable for the width of the blade. Fig.28 As shown, the blade is placed between the stops on both sides. Fig.26 As shown, the conveyor plate is long and narrow, and the width of the conveyor plate matches the width of the conveyor chain. Two blocks are arranged on each side of the positioning shaft. Fig. 27 As shown, horizontally extending wing plates 2.3 are provided on both sides of the conveying plate, the width of the wing plates is greater than the width of the conveyor chain, and a stopper is arranged on each side of the positioning shaft.

[0050] The clamping device comprises a support platform, a clamping block 4, a clamping cylinder 5, and a locking mechanism.

[0051] like Fig.17 As shown, the support platform includes two support plates 3, which are arranged in parallel and respectively set on both sides of the conveyor chain. The top surface 3.1 of the support plate is arranged horizontally and located above the moving track of the blade. The support plate is also provided with two lifting surfaces 3.2 connected to the top surface and arranged obliquely, one of which is arranged on the side of the support plate facing the feed port of the conveyor ( Figure 3 The left side of the pallet is the feed port), and the other lifting surface is set on the side of the pallet facing the conveyor discharge port ( Figure 3 The right side of the support plate is a discharge port). The top surface of the support plate is also provided with a retaining edge 3.3. The support plate is fixed to the first base through a bracket 3.4.

[0052] If the conveying device adopts Fig.26 When the blade passes the pallet, it slides upward along the lifting surface to the top surface of the pallet (the positioning axis of the conveyor plate still passes through the center hole of the blade). After passing the top surface, the blade slides downward along the lifting surface and falls completely onto the conveyor plate. Fig. 27 The blade is transported by the conveyor plate. When the blade passes through the support table, the conveyor plate drives the blade to slide upward along the lifting surface to the top surface of the support plate, and then drives the blade to slide downward along the lifting surface through the top surface.

[0053] The clamping cylinder is fixed to the top frame, and the piston rod of the clamping cylinder is arranged vertically downward. A clamping block bracket 37 is provided on the bottom surface of the top frame, and the clamping cylinder is fixed in the clamping block bracket. The clamping block is arranged above the support and below the clamping block bracket. The clamping block can also be vertically slidably positioned on the clamping block bracket through a guide rod 4.3, and the clamping block is fixed to the piston rod of the clamping cylinder. Two pressure strips 4.1 are provided on the bottom surface of the clamping block. The two pressure strips are arranged in parallel and are respectively arranged on both sides of the conveyor plate chain. The pressure strips also correspond to the upper and lower pallets (a pressure strip is arranged above the top surface of each pallet). When the piston rod of the clamping cylinder is extended, the clamping block moves downward, and the clamping block clamps and fixes the blade on the pallet through the pressure strips.

[0054] The two locking mechanisms are arranged symmetrically to the pressing block, and are respectively arranged on both sides of the pressing block facing the feed port and the discharge port of the conveyor. The locking mechanism includes a locking block 12 and a locking cylinder 13. The locking cylinder is fixed to the side of the pressing block bracket through a locking cylinder bracket 38. The piston rod of the locking cylinder is arranged horizontally. The locking block is wedge-shaped and fixed to the piston rod of the locking cylinder. The locking cylinder is used to drive the locking block to move horizontally. The top surface of the support plate is provided with a lifting surface 4.2 that cooperates with the locking blocks on both sides and is arranged obliquely.

[0055] When the clamping block presses and fixes the blade on the support plate, the two locking mechanisms are started at the same time. The locking blocks move toward each other under the drive of the locking cylinder and are horizontally inserted between the clamping block and the clamping block bracket. The clamping block is locked in the vertical direction through the cooperation of the locking block and the lifting surface. The locking cylinder continues to work while the blade is fixed, ensuring that the blade is tightly fixed to avoid shaking of the blade when the leveling device is working.

[0056] The leveling device includes a connecting frame 6, an upper correction plate, a lower correction plate, and a lifting mechanism. There are two connecting frames, which are respectively arranged on both sides of the conveyor chain. Each connecting frame is vertically slidably positioned on a support of the frame. Each support is provided with a vertically arranged slide rail 33.1 and a slide table 33.2 slidably matched with the slide rail. The connecting frame is fixed to the slide table.

[0057] The connecting frame is C-shaped, and each connecting frame is provided with an upper correction plate and a lower correction plate, which are arranged up and down. The upper correction plate is arranged on the bottom surface of the upper frame body 6.1 of the connecting frame, and the lower correction plate is arranged on the top surface of the lower frame body 6.2 of the connecting frame.

[0058] The upper correction plate comprises an upper fixing plate 7.1 fixed to the upper frame, a connecting block 7.2 rotatably positioned on the upper fixing plate, an upper pressing plate 7.3 rotatably positioned on the connecting block (for pushing the blade), and a pair of upper balancing springs (omitted in the figure). The rotation axis between the upper fixing plate and the connecting block is parallel to the moving direction of the blade ( Figure 3 The arrow in the figure indicates the moving direction), the rotation axis between the upper fixed plate and the connecting block is perpendicular to the rotation axis between the upper pressure plate and the connecting block, and the two upper balance springs are respectively arranged on both sides of the rotation axis between the upper pressure plate and the connecting block, and the two ends of the upper balance spring are respectively fixed to the upper fixed plate and the upper pressure plate. The upper balance spring can keep the upper pressure plate in a centered state to prevent the upper pressure plate from crushing the blade when the connecting frame moves.

[0059] The lower correction plate includes a lower fixed plate 8.1 fixed to the lower frame, an upper pressure plate 8.2 rotatably positioned on the lower fixed plate (for pushing the blade), and a pair of lower balance springs (omitted in the figure). The rotation axis between the upper fixed plate and the connecting block is perpendicular to the rotation axis between the lower pressure plate and the lower fixed plate. The two lower balance springs are respectively arranged on both sides of the rotation axis between the lower pressure plate and the lower fixed plate. The two ends of the lower balance spring are respectively fixed to the lower fixed plate and the lower pressure plate. The lower balance spring can keep the lower pressure plate in a centered state to prevent the lower pressure plate from crushing the blade when the connecting frame moves. A strip protrusion 8.3 is also provided on the inner side of the top surface of the lower pressure plate (the side close to the conveyor), and the strip protrusion is used to push the blade.

[0060] Each connecting frame is equipped with a lifting mechanism. The lifting mechanism includes a lifting motor 9 fixed to the first base, a screw rod 10 rotatably positioned on the support around a vertical axis, and a nut 11 meshed with the screw rod and fixed to the connecting frame. When the blade is fixed to the clamping block and the support plate, the two sides of the blade are just located between the lower correction plate and the lower correction plate; if the lifting mechanism drives the connecting frame to rise, the lower correction plate pushes the inner side of the blade (the part close to the center hole) upward through the strip-shaped protrusion, and the swingable lower pressure plate makes the strip-shaped protrusion close to the surface of the blade to prevent the blade from being damaged due to uneven force; if the lifting mechanism drives the connecting frame to descend, the upper correction plate pushes the blade downward through the upper pressure plate, and the swingable upper pressure plate close to the surface of the blade to prevent the blade from being damaged due to uneven force.

[0061] The visual inspection device is used to check the flatness of the blade. The visual inspection device includes two cameras 14, which are respectively fixed to the supports on both sides of the conveyor through camera brackets 39, and the two cameras are respectively aimed at the blade located between the upper correction plate and the upper correction plate on both sides.

[0062] The discharging device is used to take out the leveled blade from the conveying mechanism. The discharging device includes a clamp, a discharging lifting mechanism 15, and a discharging translation mechanism 16. The clamp is used to grab the blade from the conveying plate of the conveying mechanism, the discharging lifting mechanism is used to drive the clamp to move vertically, and the material translation mechanism is used to drive the discharging lifting mechanism to move horizontally. The discharging translation mechanism and the discharging lifting mechanism are both linear slide modules. The discharging translation mechanism is fixed to the column, the discharging lifting mechanism is fixed to the slider of the discharging translation mechanism, and the clamp is fixed to the slider of the discharging lifting mechanism.

[0063] The clamping jaws include a rotary motor 17, a bidirectional cylinder 18, a clamping arm 19, and a telescopic sleeve. The rotary motor is fixed to the slider of the discharging lifting mechanism, the rotating shaft of the rotary motor is arranged vertically downward, the bidirectional cylinder is fixed to the rotating shaft of the rotary motor, the telescopic rod of the bidirectional cylinder is arranged horizontally, the clamping arm is fixed to the piston rod of the bidirectional cylinder, an L-shaped hook 19.1 for grabbing the blade is provided at the bottom of the clamping arm, the outer shell 20 of the telescopic sleeve is fixed to the bottom of the bidirectional cylinder, the inner cylinder 21 of the telescopic sleeve can slide downward along the vertical direction, and the inner cavity of the telescopic sleeve is also provided with a telescopic spring (omitted in the figure) for pushing the inner cylinder downward.

[0064] The steps of grabbing the blade by the discharging device are as follows: the discharging translation mechanism drives the clamping claw to move horizontally to above the conveying plate; the discharging lifting mechanism drives the blade to descend, and the inner cylinder of the telescopic sleeve supports the surface of the blade (the positioning axis of the conveying plate extends into the inner cavity of the inner cylinder); the two-way cylinder drives the clamping arm to contract so that the hook moves to below the blade; the discharging lifting mechanism drives the clamping claw to rise and take the blade out of the conveying plate, at which time the blade is tightly fixed by the inner cylinder of the telescopic sleeve and the hook; the discharging lifting mechanism drives the clamping claw to move horizontally above the specified position; the rotary motor rotates a certain angle, and at the same time the discharging lifting mechanism drives the clamping claw to descend, and the clamping claw releases the blade to the specified position, and the blade is stacked in a spiral shape.

[0065] The controller is electrically connected to the conveyor, sensor, clamping cylinder, locking cylinder, lifting motor, camera, discharging translation mechanism, discharging lifting mechanism, rotating motor, and bidirectional cylinder. The controller is a PLC controller. All components of the present invention can be purchased from outside.

[0066] The working steps of the present invention are as follows:

[0067] 1. The worker stands at the feed port of the conveyor and places the blade on the conveyor plate (the blade can also be placed using external equipment), with the front of the blade facing downward (the side of the blade that faces upward when mowing is the front), the blade perpendicular to the conveyor chain, and the two ends of the blade extending horizontally to both sides of the conveyor;

[0068] 2. The controller sends a start signal to the conveyor, and the conveyor drives the blade to move horizontally. When passing through the clamping device, the blade will rise along the lifting surface to the top surface of the pallet, or the conveyor plate will drive the blade to rise along the lifting surface to the top surface of the pallet. At this time, the leveled blade just passes through the sensor. When the sensor detects the conveyor plate, it sends a signal to the controller. The controller sends a stop signal to the conveyor, the conveyor stops working, and the blade stays in the clamping device.

[0069] 3. The controller sends a start signal to the clamping cylinder, which drives the clamping plate to move downward to press the blade tightly against the pallet (or press the blade and the conveying plate tightly against the pallet). The controller sends a start signal to the locking cylinder, which pushes the locking block horizontally between the clamping block and the clamping block bracket to keep the blade in a clamped state.

[0070] 4. The camera obtains images of both sides of the blade, and the controller determines the flatness of both sides of the blade based on the image signal. If the flatness does not meet the requirements, it proceeds to step 5; if the flatness meets the requirements, it proceeds to step 6;

[0071] 5. According to the bending degree of the blade, the controller sends a start signal to the corresponding lifting motor, and the lifting motor drives the connecting frame to move upward or downward to adjust the blade. After the adjustment is completed, return to step 4;

[0072] 6. The controller sends a start signal to the conveyor, and the conveyor drives the blade to continue to move horizontally. When the blade moves below the discharge device, the discharge device takes out the blade from the conveyor.
