[0035] Currently, when producing cup products, packaging materials such as PP (Polypropylene) prefabricated cups, PE (Polyethylene) prefabricated cups, and PET (Polyethylene terephthalate) prefabricated cups are required. Among them, the quality inspection of the toughness and impact resistance of the cup lids is particularly important. Through impact detection, the risk of the product being squeezed and cracked during market sales can be effectively reduced. In the prior art, the visual method is usually used to detect the drop performance of the cup lids. The detection process usually requires using an auxiliary sample to fasten the cup lid, then picking up the cup body upside down and dropping it vertically so that the specimen impacts on a flat hard ground, and observing whether the cup lid is broken to detect the quality of the cup lid. However, this detection method is not only time-consuming and laborious, but the non-uniformity of manual operation will affect the detection results. Therefore, how to achieve mechanized detection, avoid artificial interference in the determination of detection results, and save time and effort, and effectively improve the detection efficiency is a problem that needs to be solved by those skilled in the art currently.

[0036] The technical solution of this embodiment will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0037] As Figures 1-4As shown in the figure, this embodiment provides a product lid cracking impact detection device for performing impact detection on the product cup lid 100. The product lid cracking impact detection device includes a stage 10, a three-axis adjustment system, an impact component 50, and a vision system 60. A number of weights 200 of different models are placed on the stage 10, and multiple product cup lids 100 can be placed on the stage 10. The stage 10 is fixed to the bottom of the three-axis adjustment system. The impact component 50 is arranged on the three-axis adjustment system and can move along the X-axis, Y-axis, and Z-axis directions respectively under the adjustment of the three-axis adjustment system. The impact component 50 can magnetically attract a single weight 200 and release the weight 200 to make it fall freely and then impact the product cup lid 100. The vision system 60 is fixed to the impact component 50 and is communicatively connected to the three-axis adjustment system. The vision system 60 can identify and position the product cup lids 100 and weights 200 placed on the stage 10 and transmit the data to the three-axis adjustment system.

[0038] Specifically, in this embodiment, the stage 10 can provide stable support for the product cup lid 100, and the impact component 50 can magnetically attract the weight 200 placed on the stage 10 and release the weight 200 to make it fall freely and then impact the product cup lid 100 to complete the impact detection. This technical means is safer and more labor-saving compared to the prior art method of using manual labor to vertically drop the product cup lid 100, and further ensures that the acting force applied to the product cup lid 100 can be evenly distributed. Further, the accuracy of the detection structure can also be ensured by the impact detection with weights 200 of different models. Specifically, in this embodiment, the impact component 50 is arranged on the three-axis adjustment system and can move along the X-axis, Y-axis, and Z-axis directions respectively under the adjustment of the three-axis adjustment system, so that the impact component 50 can move automatically and ensure accurate grasping. At the same time, a vision system 60 is also arranged on the impact component 50, and the vision system 60 is communicatively connected to the three-axis adjustment system. Then, through the vision system 60, the product cup lids 100 and weights 200 placed on the stage 10 can be identified and positioned, and the data can be transmitted to the three-axis adjustment system. While improving the accuracy of grasping the weight 200, it can also accurately align the weight 200 above the product cup lid 100 to realize the mechanized operation of the detection process, effectively avoiding the interference of human factors on the determination of the detection result, saving time and effort and improving the detection efficiency.

[0039] The following describes the specific structure of the product lid cracking impact detection device in this embodiment.

[0040] As Figure 1As shown in the figure, in this embodiment, the product lid impact detection device is mainly used for the impact detection of the product cup lid 100. It replaces the manual operation in the prior art with an automated device, and replaces the vertical drop of the product cup lid 100 with the technical means of a weight free-falling to impact the product cup lid 100, so as to improve the detection efficiency and accuracy. Specifically, the product lid impact detection device includes a stage 10, a three-axis adjustment system, an impact component 50 and a vision system 60. Different models of weights 200 are used to conduct impact tests on the product cup lid 100 at different heights, which can effectively ensure the accuracy and effectiveness of the detection results. Optionally, in this embodiment, several different models of weights 200 are placed on the stage 10, so that different models of weights 200 can be used to cause different degrees of impact effects on the product cup lid 100, effectively avoiding the vertical drop operation process of the product cup lid 100 in the prior art, thereby improving the test efficiency and ensuring the accuracy of the detection results. Further, multiple product cup lids 100 can also be placed on the stage 10, so as to avoid the process of repeatedly placing the product cup lid 100 and thus achieve batch detection, improving the test efficiency.

[0041] Optionally, the stage 10 is fixed to the bottom of the three-axis adjustment system to ensure the stable placement of the product cup lid 100 and the weight 200, and the impact component 50 is arranged on the three-axis adjustment system. Further, the impact component 50 can move along the X-axis, Y-axis and Z-axis directions respectively under the adjustment of the three-axis adjustment system, and the impact component 50 can electromagnetically attract a single weight 200. Thus, under the control of the three-axis adjustment system, the impact component 50 can quickly find the weight 200 for impact on the stage 10 and attract it, and then align it with the product cup lid 100 and lift it to a preset height to be away from the product cup lid 100. Specifically, the impact component 50 can release the weight 200 to make it perform a free-fall motion after reaching the preset detection height, and then impact on the product cup lid 100 to achieve the effect of impact detection. Exemplarily, in this embodiment, the vision system 60 is fixed on the impact component 50, so that the vision system 60 can move synchronously with the impact component 50. Optionally, the vision system 60 is communicatively connected to the three-axis adjustment system, and can identify and locate the product bottle lid 100 and the weight 200 placed on the stage 10, and transmit the measured data to the three-axis adjustment system. Thus, the three-axis adjustment system can adjust the position of the impact component 50 according to the identified data, so that the impact component 50 can reach the position where the weight 200 is located for electromagnetic attraction, and then align with the product cup lid 100 to achieve the precise impact of the weight 200 on the product cup lid 100. Therefore, with the cooperation of the vision system 60 and the three-axis adjustment system, the standardization, automation and precision of impact detection can be achieved.

[0042] As Figures 1-3As shown, specifically, in this embodiment, the three-axis adjustment system includes a Y-axis displacement component 20, an X-axis displacement component 30, and a Z-axis displacement component 40. The Y-axis displacement component 20 includes a support base 21, a Y-axis ball screw 22, a Y-axis guide rod 23, and a Y-axis motor 24. The X-axis displacement component 30 includes a first moving base 31, an X-axis ball screw 32, an X-axis guide rod 33, and an X-axis motor 34. The Z-axis displacement component 40 includes a second moving base 41, a Z-axis ball screw 42, a Z-axis guide rod 43, a Z-axis motor 44, and a third moving base 45. Optionally, in this embodiment, the stage 10 is fixedly arranged on the Y-axis displacement component 20, the X-axis displacement component 30 is slidably arranged on the Y-axis displacement component 20, the Z-axis displacement component 40 is slidably arranged on the X-axis displacement component 30, and the impact component 50 is slidably arranged on the Z-axis displacement component 40. In this embodiment, the Y-axis displacement component 20, the X-axis displacement component 30, and the Z-axis displacement component 40 are perpendicular to each other in pairs, so that the impact component 50 can be adjusted in the X-axis, Y-axis, and Z-axis directions, enabling the impact component 50 to stay at any coordinate position on the stage 10 and move according to the specific coordinate values given by the three-axis adjustment system, achieving the effects of automation and precise positioning. Exemplarily, in this embodiment, the Y-axis motor 24 is used to drive the X-axis displacement component 30 to move on the Y-axis displacement component 20, the X-axis motor 34 is used to drive the Z-axis displacement component 40 to move on the X-axis displacement component 30, and the Z-axis motor 44 is used to drive the impact component 50 to move on the Z-axis displacement component 40, thus ensuring the power source for the movement of the impact component 50 in the X-axis, Y-axis, and Z-axis directions.

[0043] As Figure 2 and Figure 3 shown, in this embodiment, the stage 10 is arranged above the support base 21. The Y-axis ball screw 22 is rotatably connected to the support base 21. The output end of the Y-axis motor 24 is connected to the Y-axis ball screw 22, and the X-axis displacement component 30 is connected to the Y-axis ball screw 22. Specifically, a first transmission block is arranged on the Y-axis ball screw 22. When the Y-axis motor 24 drives the Y-axis ball screw 22 to rotate, the first transmission block can move along the axis direction of the Y-axis ball screw 22. Specifically, the X-axis displacement component 30 is arranged on the first transmission block, thereby realizing the movement of the X-axis displacement component 30 along the Y-axis direction on the support base 21. Further, in this embodiment, there are two Y-axis guide rods 23, and the two Y-axis guide rods 23 are fixed on both sides of the support base 21, and the Y-axis ball screw 22 is located between the two Y-axis guide rods 23. Specifically, the two Y-axis guide rods 23 are both arranged in parallel and spaced apart from the Y-axis ball screw 22, and the X-axis displacement component 30 is also slidably arranged on the Y-axis guide rods 23, thereby being able to guide the X-axis displacement component 30 when it moves along the Y-axis on the Y-axis ball screw 22, ensuring the stability during the movement and further improving the accuracy of the subsequent impact detection test. AsFigure 3 As shown, exemplarily, in this embodiment, the stage 10 is formed by juxtaposing a plurality of square tubes 101, and the square tubes 101 are fastened above the support base 21 by screws. The Y-axis ball screw 22 and the Y-axis guide rod 23 are located below the stage 10. Thus, the stage 10 can provide good support for the product cup cover 100 and the weight 200, and can also shield the upper part of the Y-axis ball screw 22 and the Y-axis guide rod 23 to ensure their good transmission effect.

[0044] As Figure 1 and Figure 2 shown, similarly, in this embodiment, the first moving seat 31 is connected to the first drive block on the Y-axis ball screw 22 and is slidably disposed on the Y-axis guide rod 23, thereby realizing the connection between the X-axis displacement assembly 30 and the Y-axis displacement assembly 20. Exemplarily, the first moving seat 31 is provided with a transmission space. The stage 10 and the Y-axis displacement assembly 20 are both located in the transmission space, while the X-axis ball screw 32, the X-axis guide rod 33, and the X-axis motor 34 are all located above the transmission space. Thus, when the X-axis displacement assembly 30 moves on the Y-axis displacement assembly 20, interference between them can be avoided. Specifically, the X-axis ball screw 32 is rotatably connected to the first moving seat 31, the output end of the X-axis motor 34 is connected to the X-axis ball screw 32, and the Z-axis displacement assembly 40 is connected to the X-axis ball screw 32. Specifically, a second drive block is provided on the X-axis ball screw 32. When the X-axis motor 34 drives the X-axis ball screw 32 to rotate, the second drive block can move along the axis direction of the X-axis ball screw 32. Specifically, the Z-axis displacement assembly 40 is disposed on the second drive block, thereby realizing the movement of the Z-axis displacement assembly 40 along the X-axis direction on the first moving seat 31. Further, in this embodiment, two X-axis guide rods 33 are provided, and the two X-axis guide rods 33 are fixed on both sides of the first moving seat 31, and the X-axis ball screw 32 is located between the two X-axis guide rods 33. Specifically, the two X-axis guide rods 33 are both arranged in parallel and spaced apart from the X-axis ball screw 32, and the Z-axis displacement assembly 40 is also slidably disposed on the X-axis guide rods 33. Thus, it can guide the Z-axis displacement assembly 40 when it moves along the X-axis on the X-axis ball screw 32, ensure the stability during the movement, and further improve the accuracy of the subsequent impact detection test.

[0045] As Figure 2As shown, similarly, in this embodiment, the second moving seat 41 is connected to the second transmission block on the X-axis ball screw 32 and is slidably disposed on the X-axis guide rod 33, thereby realizing the connection between the Z-axis displacement component 40 and the X-axis displacement component 30. Specifically, the Z-axis ball screw 42 is rotatably connected to the second moving seat 41, the output end of the Z-axis motor 44 is connected to the Z-axis ball screw 42, and the impact component 50 is connected to the Z-axis ball screw 42. Specifically, the third moving seat 45 is disposed on the Z-axis ball screw 42, and the Z-axis ball screw 42 is connected to the third moving seat 45. Thus, when the Z-axis motor 44 drives the Z-axis ball screw 42 to rotate, the third moving seat 45 can move along the axial direction of the Z-axis ball screw 42, and further the impact component 50 realizes the movement along the Z-axis direction on the second moving seat 41. Further, in this embodiment, two Z-axis guide rods 43 are provided, and the two Z-axis guide rods 43 are fixed on both sides of the second moving seat 41, and the Z-axis ball screw 42 is located between the two Z-axis guide rods 43. Specifically, the two Z-axis guide rods 43 are both arranged in parallel and spaced apart from the Z-axis ball screw 42, and the impact component 50 is also slidably disposed on the Z-axis guide rods 43. Thus, it can guide the impact component 50 when it moves along the Z-axis on the Z-axis ball screw 42, ensure the stability during the movement, and further improve the accuracy of the subsequent impact detection test.

[0046] Thus, through the Y-axis displacement component 20, the X-axis displacement component 30 and the Z-axis displacement component 40 in the three-axis adjustment system, the height and position of the impact of the weight 200 can be adjusted. Further, when batch testing the product cup cover 100, there is no need to move the position of the product cup cover 100. Only need to use the three-axis adjustment system to adjust the position of the impact component 50, and it can complete the impact detection by switching between the test points, making the test process more flexible and convenient.

[0047] Combined with Figure 2 and Figure 4As shown, in this embodiment, the impact component 50 includes a fixed seat 51 and an electromagnet 52. Optionally, the fixed seat 51 is connected to the third moving seat 45 of the Z-axis displacement component 40 in the three-axis adjustment system to achieve stable installation of the impact component 50 on the Z-axis displacement component 40. Further, one end of the electromagnet 52 is fixed below the fixed seat 51, and the other end can magnetically attract or release the weight 200, so as to grab the weight 200, and after lifting the product cup lid 100 to a preset height, release the weight 200 to make it fall freely, and then conduct an impact detection test on the product cup lid 100. Exemplarily, in this embodiment, the electromagnet 52 has magnetism after being powered on to attract the weight 200, and the magnetism disappears after being powered off to release the weight 200, and the power-on connection method and control method of the impact component 50 can be set as needed. Further, a corresponding clamping device can be provided below the electromagnet 52 to tightly clamp the weight 200 after attracting it, and open it when releasing the weight 200 to avoid interfering with its free-fall motion. Specifically, during the falling process of the weight 200, it is not interfered by any external force, and weights 200 of different models can be used as needed to achieve multiple detections.

[0048] Further, in this embodiment, the vision system 60 includes a connecting plate 61, an industrial camera 62 and a vision light source 63, and the connecting plate 61 is fixedly connected to the fixed seat 51. The industrial camera 62 and the vision light source 63 are both connected to the connecting plate 61, and the vision light source 63 is located below the industrial camera 62, so as to take pictures and identify the product cup lid 100 and the weight 200 on the stage 10, and locate their positions, and transmit the corresponding position data to the three-axis adjustment system through communication connection, so as to drive the motors corresponding to the X-axis, Y-axis and Z-axis directions to adjust the position of the impact component 50. Specifically, in this embodiment, the bottom surface of the vision system 60, that is, the bottom surface of the vision light source 63, is greater than or equal to the distance of the bottom surface of the impact component 50, that is, the bottom surface of the electromagnet 52, relative to the stage 10. Thus, when the electromagnet 52 approaches the weight 200 to attract and grab it, the vision system 60 will not interfere with it, and at the same time, the vision system 60 can be protected to avoid damage and affect the subsequent measurement effect.

[0049] Exemplarily, in this embodiment, the vision light source 63 can position the weight 200 and the product cup cover 100, and can accurately measure the distance between the two. The industrial camera 62 is the most crucial part of the vision system 60. The industrial camera 62 can convert the light source signal into an ordered electrical signal, thereby directly collecting the image positions of the product cup cover 100 and the weight 200. Further, a lens is provided on the vision system 60 to adjust the angle of the light entering the industrial camera 62 and focus it to obtain a clear image. The vision system 60 is also provided with a processor, which can process and analyze the images transmitted by the industrial camera 62 to achieve the functions of target detection and measurement analysis. The vision system 60 is also provided with an interface, through which the vision system 60 can be communicatively connected to a computer or a three-axis adjustment system. Thus, by using the function of the vision system 60 in this embodiment to lock and analyze the position information of the photographed images, the positions of the weight 200 or the product cup cover 100 can be accurately grasped.

[0050] Working process: First, both the product cup cover 100 and the weight 200 are placed on the stage 10, and the industrial camera 62 and the vision light source 63 are used to automatically photograph them; then, a command is input, and the three-axis adjustment system is made to receive the command and adjust the position of the impact component 50 until it can magnetically attract and grasp the weight 200; then, the three-axis adjustment system is used again to adjust the impact component 50 with the weight 200 above the product cup cover 100 and lift it to a preset height; finally, the electromagnet 52 is powered off, so that the weight 200 falls freely towards the product cup cover 100 until it hits above it. Thus, an integrated, automated, and intelligent detection operation is achieved. Batch detection can be realized without moving the product cup cover 100, and visual positioning can be performed to accurately obtain the position of the product cup cover 100. The impact height can be adjusted by using the three-axis adjustment system and different types of weights 200 can be grasped, so that the impact force can be evenly applied to the product cup cover 100.
