Description

Technical Field

[0001] This invention belongs to the field of garden blade testing technology, specifically relating to a garden blade testing system and testing method. Background Technology

[0002] Garden blades are the core working components of outdoor plant trimming devices. They are characterized by high hardness, good wear resistance, and relatively low price. Their quality and performance directly determine the work efficiency, effect, and safety. Defects on the blade, such as cracks and cuts, may propagate under shearing forces during use, leading to breakage. Therefore, a quality inspection system is needed to inspect the blades before production to ensure the safety of the final product. Existing garden blade inspection devices have simple clamping structures, making it impossible to inspect the fixed clamped areas. Adjusting the clamping position for secondary clamping requires repositioning the blade, affecting inspection efficiency. At the same time, oil and other impurities remaining on the blade before inspection can cover the blade body, affecting the visual camera's ability to capture microscopic defects. Therefore, it is necessary to design a garden blade inspection system and method. Summary of the Invention

A connecting gear is fixedly sleeved on both the first pillar and the second pillar, and the two connecting gears mesh with each other. A clamping motor is fixedly connected to the bottom of the flip shell. The output end of the clamping motor is fixedly connected to the input end of the reduction gearbox, and the reduction gearbox is fixed on the flip shell.

[0007] As a further optimization of the present invention, a transmission gear is fixed on the third support column, and a transmission rack is symmetrically meshed on both sides of the transmission gear. The transmission rack is fixed on the sliding table, the sliding table is slidably connected in the sliding frame, the sliding frame is fixed in the flip shell, and support grooves are symmetrically opened on both sides of the flip shell.

[0008] As a further optimization of the present invention, a spring is provided on the sliding platform, one end of the spring is fixed to the top pressure platform, and a guide rod is provided on the top pressure platform, the guide rod being slidably connected to the sliding platform.

[0009] As a further optimization of the present invention, the top pressure table is rotatably connected to the clamping frame, the clamping frame is symmetrically provided with clamping pads, the clamping frame is fixed with a lower support, the lower support is provided with a limiting post, the limiting post is slidably connected in a limiting groove, and the limiting groove is opened on the sliding frame.

[0010] As a further optimization of the present invention, the pretreatment mechanism includes cylinder brackets symmetrically arranged at the bottom of the detection plate, a push cylinder is fixed on the cylinder bracket, a cleaning frame is fixedly connected to the output end of the push cylinder, a sealing shell is provided on the cleaning frame, a cleaning motor is symmetrically arranged inside the sealing shell, and a cleaning brush is fixedly connected to the output end of the cleaning motor.

[0011] As a further optimization of the present invention, the visual inspection mechanism includes an upper support fixed on the system platform, an adjustment platform slidably connected to the upper support, a mounting frame provided at the bottom of the adjustment platform, and inspection cameras evenly arranged on the mounting frame.

[0012] As a further optimization of the present invention, a lead screw motor is fixed on the upper support, and a transmission lead screw is fixedly connected to the output end of the lead screw motor. The transmission lead screw is rotatably connected to the upper support and is connected to an adjustment table.

[0013] A method for testing garden blades includes the following steps: Step 1, Blade Fixing: First, pull the pull bar along the support groove to both sides. The pull bar pushes the clamping frame to move to both sides, causing the clamping frames on both sides to separate. Place the blade to be tested between the clamping frames, release the pull bar, and the clamping frames on both sides will move towards the center under the elastic force of the spring. Then, under the elastic force of the spring, the blade is fixed and clamped by the clamping frames on both sides. Step Two, Pre-testing Process: The flipping motor drives the flipping shell to rotate 180 degrees around the axis of the support sleeve, placing the fixed blade inside the system platform. The clamping motor drives the first support column to rotate. During the rotation of the first support column, the meshing of the connecting gears causes the first and second support columns to rotate synchronously in opposite directions. Combined with the cooperation of the transmission wheel, transmission belt, and driven wheel, this causes the third support columns on both sides to rotate synchronously in opposite directions. During rotation, the meshing of the transmission gear and transmission rack causes one set of sliding platforms to move closer together, while the other symmetrically distributed set of sliding platforms moves away from each other. The closer sliding platform presses against the pressure platform via a spring, increasing the clamping force of the clamping frame on one end of the blade. Simultaneously, the sliding platforms moving away from each other cause the springs to gradually return to their original length. Once back to their original length, the springs begin to pull the clamping frame away from the sides of the blade. At this point, the limiting posts on both sides of the lower support, under the action of the limiting grooves, pull the clamping frame to rotate around the rotation axis of the pressure platform and the clamping frame, completely exposing both sides of one end of the blade. At this time, the push cylinder near the blade pushes the cleaning frame closer to the blade, while the cleaning motor drives the cleaning brush to rotate and clean both sides of the blade, removing residue. The oil and impurities left on the blade surface improve the accuracy of subsequent inspections; impurities that fall during cleaning will fall into the drop groove on the collection shell under gravity, avoiding direct cleaning that would cause impurities to fall onto the inspection plate, facilitating centralized processing later; after one end of the blade is cleaned, the clamping motor drives the first support to rotate in the opposite direction, causing the clamping frames on both sides, which were in a flipped state, to gradually reset and press against both sides of the blade again. The clamping motor drives the first support to continue rotating until the spring compression is completely uniform, after which the clamping motor drives the first support to continue rotating in the opposite direction. As one set of sliding platforms approaches each other, the other set moves away from each other. The sliding platforms that approach each other will press against the pressure plate via springs, increasing the clamping force of the clamping frame on one end of the blade. At the same time, the sliding platforms that move away from each other will cause the springs to gradually return to their original length. After returning to their original length, the springs will start to pull the clamping frame away from both sides of the blade. At this time, the limiting posts on both sides of the lower support will pull the clamping frame to rotate around the rotation axis of the pressure plate and the clamping frame under the action of the limiting groove, completely exposing both sides of the other end of the blade. Then, the pre-treatment mechanism will be used to completely clean both sides of the other end of the blade. Step 3, Data Acquisition and Inspection: The flipping motor drives the flipping shell to rotate 180 degrees around the axis of the support sleeve, flipping the fixed and cleaned blade back onto the inspection plate. The lead screw motor drives the transmission lead screw to rotate. Through the cooperation of the transmission lead screw and the adjustment table, the mounting bracket with the inspection camera moves along the axis of the transmission lead screw. During the process, the inspection camera acquires images of both sides and the cutting edge of the blade. During the movement of the inspection camera, the clamping position on the blade is changed by the adjustable clamping mechanism. The inspection camera can completely inspect both sides of the blade surface without secondary clamping, which improves the inspection efficiency. The acquired images are sent to the control module in the control cabinet. The control module combines the acquired images to detect the shape and size of the blade and the microscopic defects on the blade surface.

[0014] The beneficial effects of this invention are as follows: This invention uses a clamping motor to drive the first support column to rotate. When the first support column rotates, the meshing of connecting gears causes the first and second supports to rotate synchronously in opposite directions. Combined with the cooperation of a transmission wheel, transmission belt, and driven wheel, this causes the third supports on both sides to rotate synchronously in opposite directions. During rotation, the meshing of the transmission gear and transmission rack causes one set of sliding platforms to move closer together, while the other set of symmetrically distributed sliding platforms moves further apart. The sliding platforms that move closer together press against the pressure plate via springs, increasing the clamping force of the clamping frame on one end of the blade. Simultaneously, the sliding platforms that move further apart cause the springs to gradually return to their original length. After returning to their original length, the springs begin to pull the clamping frame away from both sides of the blade. At this point, the limiting posts on both sides of the lower support, under the action of the limiting grooves, can pull the clamping frame to rotate around the rotation axis of the pressure plate and the clamping frame, completely exposing both sides of one end of the blade. Then, the clamping motor drives the first support column to rotate in the opposite direction, completely exposing both sides of the other end of the blade. This eliminates the need for secondary clamping, allowing for complete inspection of both surfaces of the blade using a detection camera, thus improving inspection efficiency.

[0015] Before testing, this invention pushes a cylinder to bring a cleaning frame close to the blade, while a cleaning motor drives a cleaning brush to rotate and clean both sides of the blade, removing residual oil and impurities from the blade surface, thus improving the accuracy of subsequent testing.

[0016] Before cleaning both sides of the blade using the pre-treatment mechanism, the present invention uses a flipping motor to rotate the flipping shell 180 degrees around the axis of the support sleeve. After the flipping, the fixed blade is located inside the system platform. Impurities that fall during the cleaning process will fall into the drop groove on the collection shell under the action of gravity, avoiding the direct cleaning that causes impurities to fall onto the detection plate, which facilitates centralized processing later.

[0021] Please see Figure 1-4 The visual inspection mechanism 8 includes an upper support 81 fixed on the system platform 1. A slider on an adjustment platform 82 is slidably connected to a guide rail in the upper support 81. A mounting bracket 83 for supporting inspection cameras 84 is provided at the bottom of the adjustment platform 82. Three inspection cameras 84 are evenly installed on the inner wall of the mounting bracket 83, which can simultaneously perform visual inspection on the blade edge and both sides of the blade. A lead screw motor 85 is fixed on the upper support 81. A transmission lead screw 86 is fixedly connected to the output end of the lead screw motor 85. The transmission lead screw 86 is rotatably connected to the upper support 81 through a bearing. The adjustment platform 82 is connected to the transmission lead screw 86 through an internally embedded ball nut. The lead screw motor 85 drives the transmission lead screw 86 to move the adjustment platform 82 along the guide rail in the upper support 81.

[0022] Please see Figure 1-4 The flipping mechanism 3 includes a flipping motor 31 fixedly installed on the detection plate 2. The output end of the flipping motor 31 is fixedly connected to one side of the flipping shell 32, and a support shaft is provided on the other side of the flipping shell 32. The support shaft is rotatably connected to the support sleeve 33 through a bearing, and the support sleeve 33 is fixed on the detection plate 2.

[0023] Please see Figure 4-7The adjustable clamping mechanism 4 includes a first support column 41 and a second support column 42 rotatably connected to the tilting shell 32 via bearings. Connecting gears 43 are fixedly sleeved on both the first support column 41 and the second support column 42, and the two connecting gears 43 mesh with each other. A clamping motor 44 is fixedly connected to the bottom of the tilting shell 32. The output end of the clamping motor 44 is fixedly connected to the input end of a reduction gearbox, which is fixed to the tilting shell 32. The output end of the reduction gearbox is fixedly connected to the first support column 41. During the operation of the reduction gearbox driven by the clamping motor 44, the first support column 41 can be driven... The rotation of column 41, in conjunction with the meshing connecting gears 43 on the first and second columns 41, allows the second column 42 to rotate synchronously in the opposite direction relative to the first column 41. Both the first and second columns 41 are fixedly mounted with transmission wheels 45, around which a transmission belt 46 is wound. The transmission belt 46 is wound around a driven wheel 47, which is fixedly sleeved on the third column 48. The bottom end of the third column 48 is rotatably connected to the flipping shell 32 via a bearing. A transmission gear 49 is fixed on the third column 48. A transmission rack 50 is symmetrically meshed on the gear 49. The transmission rack 50 is fixed on the sliding table 51. The sliding table 51 is slidably connected to the sliding frame 52. The sliding frame 52 is symmetrically fixed in the flip shell 32. Support grooves 61 are symmetrically opened on both sides of the flip shell 32. Pull bars 62 are slidably connected in the support grooves 61. A spring 53 is provided on the sliding table 51. One end of the spring 53 is fixed to the top pressure table 54. A guide rod 55 is fixed on the top pressure table 54. The guide rod 55 is slidably connected to the sliding table 51. The top pressure table 54 is rotatably connected to the clamping frame 5. On the 6, the clamping frame 56 corresponds to the position of the pull bar 62. The clamping frame 56 is symmetrically provided with clamping pads 57. Pulling the pull bar 62 along the support groove 61 to both sides can cause the clamping pads 57 to move away from each other. The clamping frame 56 is fixed with a lower support 58. The lower support 58 is symmetrically provided with limit posts 59. The limit posts 59 are slidably connected in the limit groove 60. The limit groove 60 is opened on the sliding frame 52. After the clamping frame 56 follows the top pressure table 54 to separate from the blade surface, the limit posts 59 will pull the clamping frame 56 to flip under the action of the limit groove 60.

[0024] Please see Figure 2 The pretreatment mechanism 7 includes cylinder brackets 71 symmetrically arranged at the bottom of the detection plate 2. The cylinder brackets 71 are used to support the push cylinder 72. The output end of the push cylinder 72 is fixedly connected to a cleaning frame 73. A sealing shell 74 is provided on the cleaning frame 73. A cleaning motor 75 is symmetrically arranged inside the sealing shell 74. The sealing shell 74 is used to seal and protect the cleaning motor 75. A cleaning brush 76 is fixedly connected to the output end of the cleaning motor 75. During the process of the cleaning motor 75 driving the cleaning brush 76 to rotate, the cleaning brush 76 can clean the oil and impurities adhering to the blade surface.

[0025] Please see Figure 8A method for testing garden blades includes the following steps: Step 1, Blade Fixing: First, pull the pull bar 62 to both sides along the support groove 61. The pressure of the pull bar 62 on the clamping frame 56 causes the clamping frames 56 on both sides to separate. Place the blade to be tested between the clamping frames 56. Release the pull bar 62. The clamping frames 56 on both sides will move towards the center under the elastic force of the spring 53. Then, under the elastic force of the spring 53, the blade will be fixed by the clamping frames 56 on both sides. Step 2, Pre-testing: The flipping motor 31 drives the flipping shell 32 to rotate 180 degrees around the axis of the support sleeve 33. After flipping, the fixed blade is inside the system platform 1. The clamping motor 44 drives the first support column 41 to rotate. When the first support column 41 rotates, the meshing of the connecting gear 43 causes the first support column 41 and the second support column 42 to rotate synchronously in opposite directions. With the cooperation of the transmission wheel 45, the transmission belt 46 and the driven wheel 47, the third support columns 48 on both sides rotate synchronously in opposite directions. During the rotation, the meshing of the transmission gear 49 and the transmission rack 50 causes one set of sliding tables 51 to move closer to each other, while the other set of symmetrically distributed sliding tables 51 move closer to each other. As the sliding tables 51 move away from each other and move closer together, the spring 53 presses against the pressure table 54, increasing the clamping force of the clamping frame 56 on one end of the blade. Simultaneously, the moving sliding tables 51 gradually restore the spring 53 to its original length. After returning to its original length, the spring 53 begins to pull the clamping frame 56 away from both sides of the blade. At this time, the limiting posts 59 on both sides of the lower support 58, under the action of the limiting grooves 60, pull the clamping frame 56 to rotate around the rotation axis of the pressure table 54 and the clamping frame 56, completely exposing both sides of one end of the blade. At this point, the pushing cylinder 72 near the blade pushes the cleaning frame 73 closer to the blade, while the cleaning motor 75 drives the cleaning brush 76 to rotate and clean the blade. Both sides are cleaned to remove residual oil and impurities from the blade surface, improving subsequent detection accuracy. Impurities falling during cleaning will fall into the drop groove 6 on the collection shell 5 under gravity, preventing them from falling onto the detection plate 2 during direct cleaning and facilitating centralized processing later. After one end of the blade is cleaned, the clamping motor 44 drives the first support column 41 to rotate in the opposite direction, causing the clamping frames 56, which were in a flipped state on both sides, to gradually reset and press against both sides of the blade again. The clamping motor 44 drives the first support column 41 to continue rotating until the compression of the spring 53 is completely uniform. Then, the clamping motor 44 drives the first support column 41 to continue rotating in the opposite direction, forming a set of sliding... As the moving platforms 51 move closer together, another set of sliding platforms 51 move further apart. The sliding platforms 51 that move closer together will press against the pressing platform 54 through the spring 53, increasing the clamping force of the clamping frame 56 on one end of the blade. At the same time, the sliding platforms 51 that move further apart will cause the spring 53 to gradually return to its original length. After returning to its original length, the spring 53 will start to pull the clamping frame 56 away from both sides of the blade. At this time, the limiting posts 59 on both sides of the lower support 58 will pull the clamping frame 56 around the rotation axis of the pressing platform 54 and the clamping frame 56 under the action of the limiting groove 60, so that both sides of the other end of the blade are completely exposed. Then, the pre-processing mechanism 7 will be used to completely clean both sides of the other end of the blade. Step 3, Data Acquisition and Inspection: The flipping motor 31 drives the flipping shell 32 to continue flipping 180 degrees around the axis of the support sleeve 33, flipping the fixed and cleaned blade back above the inspection plate 2. The lead screw motor 85 drives the transmission lead screw 86 to rotate. Through the cooperation of the transmission lead screw 86 and the adjustment table 82, the mounting bracket 83 with the inspection camera 84 moves along the axis of the transmission lead screw 86. During the process, the inspection camera 84 acquires images of both sides and the cutting edge of the blade. During the movement of the inspection camera 84, the clamping position on the blade is changed by the adjustable clamping mechanism 4. The inspection camera 84 can completely inspect both sides of the blade without secondary clamping, which improves the inspection efficiency. The acquired images are sent to the control module in the control cabinet 9. The control module combines the acquired images to detect the shape and size of the blade and the micro-defects on the blade surface.

[0026] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.

The pull bar pushes the clamping frame to move to both sides, causing the clamping frames on both sides to separate. Place the blade to be tested between the clamping frames, release the pull bar, and the clamping frames on both sides will move towards the center under the elastic force of the spring. Then, under the elastic force of the spring, the blade is fixed and clamped by the clamping frames on both sides. Step Two, Pre-testing Process: The flipping motor drives the flipping shell to rotate 180 degrees around the axis of the support sleeve, placing the fixed blade inside the system platform. The clamping motor drives the first support column to rotate. During the rotation of the first support column, the meshing of the connecting gears causes the first and second support columns to rotate synchronously in opposite directions. Combined with the cooperation of the transmission wheel, transmission belt, and driven wheel, this causes the third support columns on both sides to rotate synchronously in opposite directions. During rotation, the meshing of the transmission gear and transmission rack causes one set of sliding platforms to move closer together, while the other symmetrically distributed set of sliding platforms moves away from each other. The closer sliding platform presses against the pressure platform via a spring, increasing the clamping force of the clamping frame on one end of the blade. Simultaneously, the sliding platforms moving away from each other cause the springs to gradually return to their original length. Once back to their original length, the springs begin to pull the clamping frame away from the sides of the blade. At this point, the limiting posts on both sides of the lower support, under the action of the limiting grooves, pull the clamping frame to rotate around the rotation axis of the pressure platform and the clamping frame, completely exposing both sides of one end of the blade. At this time, the push cylinder near the blade pushes the cleaning frame closer to the blade, while the cleaning motor drives the cleaning brush to rotate and clean both sides of the blade, removing residue. The oil and impurities left on the blade surface improve the accuracy of subsequent inspections; impurities that fall during cleaning will fall into the drop groove on the collection shell under gravity, avoiding direct cleaning that would cause impurities to fall onto the inspection plate, facilitating centralized processing later; after one end of the blade is cleaned, the clamping motor drives the first support to rotate in the opposite direction, causing the clamping frames on both sides, which were in a flipped state, to gradually reset and press against both sides of the blade again. The clamping motor drives the first support to continue rotating until the spring compression is completely uniform, after which the clamping motor drives the first support to continue rotating in the opposite direction. As one set of sliding platforms approaches each other, the other set moves away from each other. The sliding platforms that approach each other will press against the pressure plate via springs, increasing the clamping force of the clamping frame on one end of the blade. At the same time, the sliding platforms that move away from each other will cause the springs to gradually return to their original length. After returning to their original length, the springs will start to pull the clamping frame away from both sides of the blade. At this time, the limiting posts on both sides of the lower support will pull the clamping frame to rotate around the rotation axis of the pressure plate and the clamping frame under the action of the limiting groove, completely exposing both sides of the other end of the blade. Then, the pre-treatment mechanism will be used to completely clean both sides of the other end of the blade. Step 3, Data Acquisition and Inspection: The flipping motor drives the flipping shell to rotate 180 degrees around the axis of the support sleeve, flipping the fixed and cleaned blade back onto the inspection plate. The lead screw motor drives the transmission lead screw to rotate. Through the cooperation of the transmission lead screw and the adjustment table, the mounting bracket with the inspection camera moves along the axis of the transmission lead screw. During the process, the inspection camera acquires images of both sides and the cutting edge of the blade. During the movement of the inspection camera, the clamping position on the blade is changed by the adjustable clamping mechanism. The inspection camera can completely inspect both sides of the blade surface without secondary clamping, which improves the inspection efficiency. The acquired images are sent to the control module in the control cabinet. The control module combines the acquired images to detect the shape and size of the blade and the microscopic defects on the blade surface.
