Description

Technical Field

[0001] This invention relates to the field of mold inspection technology, and specifically to a mold visual inspection device and its inspection method. Background Technology

[0002] After production, the mold needs to be inspected to ensure that there are no defects such as cracks, scratches, or deformation on the surface of the mold cavity, so as to guarantee the quality of the finished product during use.

[0003] Chinese patent CN222273287U discloses a device for detecting surface defects in plastic injection molds, including a device body containing a detector. A conveyor belt runs through the inner side of the detector. A detection head is located inside the detector and above the conveyor belt. A base is located at the lower end of the conveyor belt, and a first cylinder is mounted at the center of the base. A fixed plate is located at the upper end of the first cylinder. A gear shaft is rotatably mounted on the upper end of the fixed plate, and a movable plate is fixed to the upper end of the gear shaft. A rack is located on one side of the gear shaft, and a second cylinder is connected to one end of the rack. Third cylinders are located on both sides of the conveyor belt. This device enables lifting, raising, clamping, and flipping of the workpiece to be inspected, facilitating defect detection on the bottom surface of the workpiece. It also allows for control of the rotation angle of the workpiece to ensure complete defect detection on each surface. However, this device and existing technologies still have the following problems:

[0004] The mold is heavy, and lifting, clamping and flipping it is not only complicated and inefficient, but also puts a heavy load on the equipment. In addition, the mold needs to be rotated 90 degrees when picking it up and putting it down, which is not convenient for the inspection operation. The mold surface may be covered with dirt and impurities, which will affect the inspection accuracy.

[0005] Based on this, the present invention designs a mold visual inspection device and its inspection method to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mold visual inspection device and inspection method.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A mold visual inspection device includes a base;

[0009] A mold splitting and joining support mechanism is installed on the base. The mold splitting and joining support mechanism includes a moving mold support assembly, a fixed mold support assembly, and a first linear module. The moving mold support assembly and the fixed mold support assembly are used to support and limit the moving mold and the fixed mold, respectively. The moving mold support assembly and the first linear module are fixedly installed on the left and right sides of the base. The moving end of the first linear module is fixedly installed with the fixed mold support assembly.

[0010] The base is also equipped with a uniform mold cavity cleaning mechanism and an all-round detection mechanism, which are located between the moving mold support assembly and the fixed mold support assembly.

[0011] The all-round inspection mechanism includes a third linear module, a vertical moving component, and a multi-angle cooperating inspection component. The third linear module is fixedly installed on the base. The vertical moving component is equipped with a vertical moving component at its moving end. Two sets of multi-angle inspection components are installed at the moving end of the vertical moving component, which are used to inspect the mold cavities of the fixed mold and the moving mold for defects.

[0012] Furthermore, the vertical movement assembly includes a motor, a support frame, a connecting plate, a lead screw, straight rods, and a vertical moving plate. The support frame is fixedly installed at the moving end of the third linear module. The connecting plate is located on the upper side of the support frame, and two straight rods are fixedly installed between the connecting plate and the support frame. The lead screw is located between the two straight rods, and its two ends are rotatably connected to the support frame and the connecting plate, respectively. The motor is fixedly installed at the lower end of the support frame, and the output end of the motor is fixedly connected to the lead screw. The vertical moving plate is threadedly connected to the lead screw through a threaded sleeve, and the vertical moving plate is slidably connected to the straight rods.

[0013] Furthermore, the multi-angle detection component includes a first scanner, a second scanner, and a linkage rotating component. The linkage rotating component is mounted on a vertical moving plate, and the first scanner is fixedly mounted on the moving end of the linkage rotating component. The second scanner is also fixedly mounted on the vertical moving plate.

[0014] Furthermore, the linkage rotating assembly includes a second gear, a second rack, a rotating rod, and a mounting plate. The rotating rod is rotatably connected to the vertical moving plate via a bearing. One end of the rotating rod is fixedly connected to the mounting plate, and the other end of the rotating rod is fixedly connected to the second gear. The second rack is fixedly connected to the straight rod and meshes with the second gear.

[0015] The mounting plate is V-shaped, with the end of the mounting plate away from the rotating rod fixedly connected to the first scanner.

[0016] Furthermore, the uniform cleaning mechanism for the mold cavity includes a second linear module, a lifting and rotating cleaning component, and a dust and impurity collection component. The second linear module is fixedly installed on the base, and the lifting and rotating cleaning component and the dust and impurity collection component are installed on the moving end of the base. The lifting and rotating cleaning component is used to clean the mold cavity of the mold on both sides, and the dust and impurity collection component is used to collect dust and impurities on the lifting and rotating cleaning component.

[0017] Furthermore, the lifting rotary cleaning assembly includes a rotary cleaning assembly and a reciprocating lifting assembly. The rotary cleaning assembly is installed at the moving end of the second linear module, and the reciprocating lifting assembly is installed at the lower end of the rotary cleaning assembly.

[0018] Furthermore, the rotating cleaning assembly includes a rotating shaft, a brush roller, a first gear, and a first rack. The first gear is rotatably mounted on the lower end of the moving end of the second linear module via a bearing. The rotating shaft is connected to the first gear via a key, allowing the rotating shaft to slide along the axial direction of the first gear and rotate synchronously with it. A receiving groove is provided on the base to avoid the rotating shaft. A first rack is fixedly installed on the inner wall of the receiving groove, and the first gear and the first rack are meshed together. A brush roller is fixedly installed on the upper end of the rotating shaft.

[0019] Furthermore, the reciprocating lifting assembly includes a roller and a limiting guide rail. The roller is rotatably mounted on the lower end of the rotating shaft, and the limiting guide rail is fixedly mounted on the lower end of the base. A wave groove is provided on the side of the limiting guide rail to be rotatably connected to the roller.

[0020] Furthermore, the dust and impurity cleaning assembly includes a desorption hood and an air suction pipe. The two desorption hoods are fixedly installed on the moving end of the second linear module and located on the front and rear sides of the brush roller. The air suction pipe is fixedly connected to the desorption hood through a connector and is located on the inner side of the brush roller. The air suction pipe is evenly provided with multiple air suction holes facing the molds on both sides.

[0021] To better achieve the objectives of this invention, this invention also provides a detection method for a mold visual inspection device, comprising the following steps:

[0022] Step 1: Hoist the mold onto the moving mold support assembly and the fixed mold support assembly. Use the first linear module to control the fixed mold support assembly to move away from the moving mold support assembly, thus separating the fixed mold and the moving mold.

[0023] Step 2: The second linear module drives the brush roller to move between the fixed mold and the moving mold. During the process of moving the brush roller, it will move back and forth vertically and rotate at the same time, cleaning the fixed mold and the moving mold simultaneously. Dirt and impurities adhere to the brush roller, and when the brush roller passes through the desorption cover, the dirt on the brush roller is sucked away and collected through the desorption cover.

[0024] Step 3: The third linear module drives the vertical moving component to move between the fixed mold and the moving mold, and then the vertical moving plate moves back and forth vertically. During the movement of the vertical moving plate, the first scanner continuously shakes its head to scan the mold without blind spots, while the second scanner works together to determine whether there are scratches or other defects on the surface of the mold.

[0025] Step 4: Increase the distance between the fixed mold and the moving mold by controlling the first linear module, and apply red lead to both the fixed and moving molds;

[0026] Step 5: Control the fixed mold to impact the moving mold to close the mold using the first linear module, and then observe the coloring of the parting surface of the fixed mold and the moving mold to judge their fit performance. Compared with the prior art, the beneficial effects of this invention are as follows: 1. The mold is hoisted onto the moving mold support assembly and the fixed mold support assembly. The first linear module controls the fixed mold support assembly to move away from the moving mold support assembly, so that the fixed mold and the moving mold are separated. Then, the mold cavity uniform cleaning mechanism is controlled to pass between the fixed mold and the moving mold to clean them, so as to avoid dirt and impurities remaining on the mold surface and interfering with the subsequent test results. After the cleaning operation of the mold cavity uniform cleaning mechanism is completed, the third linear module drives the vertical moving assembly to move between the fixed mold and the moving mold. Then, the vertical moving assembly controls the multi-angle cooperation detection assembly to move vertically, and simultaneously performs defect detection on the fixed mold and the moving mold. After each part is detected, the third linear module drives the vertical moving assembly to advance a part until all parts of the fixed mold and the moving mold are detected, realizing all-round detection of the mold. The entire detection process does not require manual intervention and is suitable for continuous detection of batch molds. The fixed mold and the moving mold can be detected at the same time in one operation, which effectively improves the detection efficiency. It also facilitates the hoisting and transportation of the mold. The mold that passes the inspection can be directly closed and moved away for storage.

[0027] 2. The motor drives the lead screw to rotate, which in turn drives the vertical moving plate to move vertically under the limiting action of the straight rod. During the movement of the vertical moving plate, the second gear and the second rack work together to drive the rotating rod to rotate, which in turn drives the first scanner to rotate through the mounting plate, achieving the head-shaking effect of the first scanner. This allows the first scanner to scan the mold without blind spots, obtaining a realistic model of the mold to ensure the accuracy of the judgment results. At the same time, the second scanner is always perpendicular to the mold to help judge whether there are scratches or other defects on the mold surface.

[0028] 3. While the brush roller rotates, it also moves vertically back and forth, effectively increasing the cleaning efficiency and uniformity of the fixed and moving molds. During the cleaning operation, the suction pipe continuously draws air through the suction hole, causing dirt and impurities to adhere to the brush roller. As the brush roller passes through the desorption cover, the dirt on the brush roller is sucked away and collected, thus preventing the dirt and impurities from falling and contaminating the mold again after cleaning.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0043] In some embodiments, please refer to the accompanying drawings. Figures 1-9 A mold visual inspection device includes a base 1;

[0044] The base 1 is equipped with a mold splitting and joining support mechanism 2. The mold splitting and joining support mechanism 2 includes a moving mold support assembly, a fixed mold support assembly, and a first linear module 24. The moving mold support assembly and the fixed mold support assembly are used to support and limit the moving mold and the fixed mold, respectively. The moving mold support assembly and the first linear module 24 are fixedly installed on the left and right sides of the base 1. The moving end of the first linear module 24 is fixedly installed with the fixed mold support assembly.

[0045] The base 1 is also equipped with a uniform mold cavity cleaning mechanism 3 and an all-round detection mechanism 4, which are located between the moving mold support assembly and the fixed mold support assembly.

[0046] The all-round inspection mechanism 4 includes a third linear module 413, a vertical moving component, and a multi-angle detection component. The third linear module 413 is fixedly installed on the base 1. The vertical moving component is installed at the moving end of the third linear module 413. Two sets of multi-angle detection components are installed at the moving end of the vertical moving component for defect detection of the mold cavity of the fixed mold and the moving mold, respectively.

[0047] In this invention, the mold is first hoisted onto the moving mold support assembly and the fixed mold support assembly. The first linear module 24 controls the fixed mold support assembly to move away from the moving mold support assembly, causing the fixed mold and the moving mold to separate. Then, the mold cavity uniform cleaning mechanism 3 is controlled to pass between the fixed mold and the moving mold to clean them, preventing dirt and impurities from remaining on the mold surface and interfering with subsequent inspection results. After the cleaning operation of the mold cavity uniform cleaning mechanism 3 is completed, the third linear module 413 drives the vertical moving assembly to move between the fixed mold and the moving mold. Then, the vertical moving assembly controls the multi-angle detection assembly to move vertically, simultaneously performing defect detection on the fixed mold and the moving mold. After each part is inspected, the third linear module 413 drives the vertical moving assembly to advance a part until all parts of the fixed mold and the moving mold are inspected, realizing all-round inspection of the mold. The entire inspection process does not require manual intervention and is suitable for continuous inspection of batch molds. The fixed mold and the moving mold can be inspected at the same time in one operation, which effectively improves the inspection efficiency. It also facilitates the hoisting and transportation of the mold. The qualified mold can be directly closed and moved away for storage.

[0048] After defect detection of the mold, the distance between the fixed mold and the moving mold is increased by controlling the first linear module 24. Red lead or blue lead can be applied to the fixed mold or the moving mold manually. Then, the fixed mold and the moving mold are quickly closed by controlling the first linear module 24. The matching performance of the two can be judged by observing the coloring of the parting surface of the fixed mold and the moving mold.

[0049] Please see Figure 8 and Figure 9 The vertical moving assembly includes a motor 41, a support frame 42, a connecting plate 43, a lead screw 44, a straight rod 45, and a vertical moving plate 46. The support frame 42 is fixedly installed at the moving end of the third linear module 413. The connecting plate 43 is located on the upper side of the support frame 42, and two straight rods 45 are fixedly installed between the connecting plate 43 and the support frame 42. The lead screw 44 is located between the two straight rods 45, and its two ends are rotatably connected to the support frame 42 and the connecting plate 43, respectively. The motor 41 is fixedly installed at the lower end of the support frame 42, and the output end of the motor 41 is fixedly connected to the lead screw 44. The vertical moving plate 46 is threadedly connected to the lead screw 44 through a threaded sleeve, and the vertical moving plate 46 is slidably connected to the straight rod 45.

[0050] The multi-angle matching detection component includes a first scanner 411, a second scanner 412, and a linkage rotating component. The linkage rotating component is mounted on the vertical moving plate 46. The first scanner 411 is fixedly mounted on the moving end of the linkage rotating component, and the second scanner 412 is also fixedly mounted on the vertical moving plate 46.

[0051] The linkage rotating assembly includes a second gear 47, a second rack 48, a rotating rod 49, and a mounting plate 410. The rotating rod 49 is rotatably connected to the vertical moving plate 46 via a bearing. One end of the rotating rod 49 is fixedly connected to the mounting plate 410, and the other end of the rotating rod 49 is fixedly connected to the second gear 47. The second rack 48 is fixedly connected to the straight rod 45, and the second rack 48 is meshed with the second gear 47.

[0052] The mounting plate 410 is configured as a V-shape, and the end of the mounting plate 410 away from the rotating rod 49 is fixedly connected to the first scanner 411.

[0053] In this embodiment, the first scanner 411 is a 3D scanner, and the second scanner 412 is a high-definition camera;

[0054] In existing technologies, a common method is to slowly scan the mold cavity with a handheld 3D scanner to quickly model the mold and determine whether the mold is deformed or has dimensional deviations. However, during the handheld process, the 3D scanner needs to be constantly shaken to avoid the four corners and to achieve a complete model of the mold. This method is not only labor-intensive, but also inconvenient for scanning large molds and not conducive to the inspection of batch molds.

[0055] In this invention, the motor 41 drives the lead screw 44 to rotate, which in turn drives the vertical moving plate 46 to move vertically under the limiting action of the straight rod 45. During the movement of the vertical moving plate 46, the second gear 47 and the second rack 48 work together to drive the rotating rod 49 to rotate, which in turn drives the first scanner 411 to rotate through the mounting plate 410, achieving the head-shaking effect of the first scanner 411. This allows the first scanner 411 to scan the mold without blind spots, obtaining a true model of the mold to ensure the accuracy of the judgment results. At the same time, the second scanner 412 is always perpendicular to the mold, working together to judge whether there are scratches or other defects on the surface of the mold.

[0056] Please see Figures 1-7 The uniform cleaning mechanism 3 for the mold cavity includes a second linear module 31, a lifting and rotating cleaning component, and a dust and impurity collection component. The second linear module 31 is fixedly installed on the base 1, and the lifting and rotating cleaning component and the dust and impurity collection component are installed on the moving end of the base 1. The lifting and rotating cleaning component is used to clean the mold cavity of the mold on both sides, and the dust and impurity collection component is used to collect dust and impurities on the lifting and rotating cleaning component.

[0057] The lifting rotary cleaning assembly includes a rotary cleaning assembly and a reciprocating lifting assembly. The rotary cleaning assembly is installed at the moving end of the second linear module 31, and the reciprocating lifting assembly is installed at the lower end of the rotary cleaning assembly.

[0058] The rotating cleaning assembly includes a rotating shaft 32, a brush roller 33, a first gear 34, and a first rack 35. The first gear 34 is rotatably mounted on the lower end of the moving end of the second linear module 31 via a bearing. The rotating shaft 32 is connected to the first gear 34 via a key, allowing the rotating shaft 32 to slide along the axial direction of the first gear 34 and rotate synchronously with the first gear 34. A receiving groove is provided on the base 1 to avoid the rotating shaft 32. The first rack 35 is fixedly installed on the inner wall of the receiving groove, and the first gear 34 and the first rack 35 are meshed together. The brush roller 33 is fixedly installed on the upper end of the rotating shaft 32.

[0059] The reciprocating lifting assembly includes a roller 36 and a limiting guide rail 37. The roller 36 is rotatably mounted on the lower end of the rotating shaft 32, and the limiting guide rail 37 is fixedly mounted on the lower end of the base 1. A wave groove is provided on the side of the limiting guide rail 37 to be tactilely connected with the roller 36.

[0060] The dust and impurity cleaning assembly includes a desorption hood 38 and an air suction pipe 39. The two desorption hoods 38 are fixedly installed on the moving end of the second linear module 31 and located on the front and rear sides of the brush roller 33. The desorption hoods 38 are connected to the air inlet of the external air extraction device (not shown in the figure) through an air passage. The air suction pipe 39 is fixedly connected to the desorption hoods 38 through a connector and is located inside the brush roller 33. The air suction pipe 39 is connected to the air inlet of the external air extraction device (not shown in the figure) through an air passage. The air suction pipe 39 has a plurality of air suction holes 310 evenly opened on it, facing the molds on both sides.

[0061] In this embodiment, the air extraction device is a blower / suction machine.

[0062] In this invention, the second linear module 31 drives the brush roller 33 to advance between the fixed mold and the moving mold. During the advancement of the brush roller 33, the first gear 34 and the first rack 35 cooperate to drive the brush roller 33 to rotate, cleaning the mating surfaces of the fixed mold and the moving mold. At the same time, the roller 36 rolls in the wave groove of the limiting guide rail 37, so that the brush roller 33 rotates while also moving vertically back and forth, effectively increasing the cleaning efficiency and uniformity of the brush roller 33 on the fixed mold and the moving mold. While the brush roller 33 is cleaning, the suction pipe 39 continuously draws air through the suction hole 310, causing dirt and impurities to adhere to the brush roller 33. As the brush roller 33 passes through the desorption cover 38, the dirt on the brush roller 33 is sucked away and collected, thereby preventing the dirt and impurities after cleaning from falling and contaminating the mold again.

[0063] The moving mold support assembly includes a support base plate 21, a support side plate 22, and U-shaped limiting posts 23. The support base plate 21 is fixedly installed on the base 1, and the support side plate 22 is fixedly installed on the support base plate 21. The two U-shaped limiting posts 23 are symmetrically fixedly installed at the front and rear ends of the support base plate 21, and the U-shaped limiting posts 23 are connected to the support side plate 22. The support base plate 21, the support side plate 22, and the U-shaped limiting posts 23 work together to achieve stable support and limiting effect for the mold, control the opening and closing of the fixed mold and the moving mold, and facilitate the lifting operation of the mold.

[0064] The fixed mold support assembly and the moving mold support assembly have the same structure, and the support base plate 21 of the fixed mold support assembly is fixedly installed on the moving end of the first linear module 24.

[0065] In some embodiments, such as Figures 1-9 As shown, in a preferred embodiment of the present invention, a detection method for a mold visual inspection device includes the following steps:

[0066] Step 1: Hoist the mold onto the moving mold support assembly and the fixed mold support assembly. Control the fixed mold support assembly away from the moving mold support assembly through the first linear module 24 to separate the fixed mold and the moving mold.

[0067] Step 2: The second linear module 31 drives the brush roller 33 to move between the fixed mold and the moving mold. During the advance, the brush roller 33 will move back and forth vertically and rotate at the same time, cleaning the fixed mold and the moving mold simultaneously. Dirt and impurities adhere to the brush roller 33, and when the brush roller 33 passes through the desorption cover 38, the dirt on the brush roller 33 is sucked away and collected through the desorption cover 38.

[0068] Step 3: The third linear module 413 drives the vertical moving component to move between the fixed mold and the moving mold, and then the vertical moving plate 46 moves back and forth vertically. During the movement of the vertical moving plate 46, the first scanner 411 continuously shakes its head to scan the mold without dead angles, while the second scanner 412 cooperates to judge whether there are scratches or other defects on the surface of the mold.

[0069] Step 4: Control the distance between the fixed mold and the moving mold to increase through the first linear module 24, and apply red lead to both the fixed and moving molds;

[0070] Step 5: Control the fixed mold to impact the moving mold to close the mold by controlling the first linear module 24, and then observe the coloring of the parting surface of the fixed mold and the moving mold to judge their fit performance.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
