[0002] The mobile phone middle frame is generally made of profile aluminum or die-cast aluminum. The production processes of the two are different. For the die-cast aluminum mobile phone middle frame, the die-casting process is generally required. In the die-casting process, due to the excessive gas contained in the metal, the molten metal cannot be perfectly replaced with the gas during the casting process, resulting in some gas remaining inside the casting to form small holes, which are called sand holes.

[0046] An embodiment of the present application provides a middle frame sand hole X-ray detection device for detecting defects such as sand holes inside materials. The materials include but are not limited to castings such as mobile phone middle frames. For details, see Figure 2 as well as Figure 3 In one embodiment, a middle frame sand hole X-ray detection device includes a carrying mechanism 10, a ray generating mechanism 20 and a ray receiving mechanism 30.

[0047] The carrying mechanism 10 includes a carrying platform 11 and a first driving assembly 12 connected to the carrying platform 11 . The carrying platform 11 is used to carry materials, and the first driving assembly 12 is used to drive the carrying platform 11 to move between a loading station and a detection station along a first direction.

[0048] The ray generating mechanism 20 is arranged on one side of the carrying mechanism 10. For example, the ray generating mechanism 20 is arranged below the carrying mechanism 10. It includes a ray source 21 and a second driving component 22 connected to the ray source 21. The second driving component 22 is used to drive the ray source 21 to move along the second direction and / or the third direction. The ray source 21 is used to emit detection rays to the material entering the detection station. For example, the detection rays can be X-rays. The first direction, the second direction and the third direction are arranged to intersect. For example, Figure 2 The Y direction is the first direction, the X direction is the second direction, and the Z direction is the third direction.

[0049] The ray receiving mechanism 30 is arranged on the other side of the carrying mechanism 10. For example, the ray receiving mechanism 30 is arranged above the carrying mechanism 10. The ray receiving mechanism 30 includes a detector 31 and a third driving assembly 32 connected to the detector 31. The third driving assembly 32 is used to drive the detector 31 to move along the second direction and the third direction. The detector 31 is used to receive the detection ray passing through the material to generate a detection image.

[0050] In the above-mentioned middle frame sand hole X-ray detection equipment, the material to be detected is carried on the carrier 11, and then the first drive component 12 drives the carrier 11 to move between the loading station and the detection station, so as to realize the automatic loading and unloading of the material to be detected. When the material enters the detection station, the second drive component 22 drives the ray source 21 to move to one side of the material, and the third drive component 32 drives the detector 31 to move to the other side of the material, so that the ray source 21 and the detector 31 can be aligned with the material from the upper and lower sides of the material respectively to ensure the accuracy of subsequent detection. Finally, the ray source 21 emits detection rays to the material. When there are defects such as sand holes inside the material, due to the different absorption rates of the material at the defective part to the detection rays, after the detection rays pass through the material and are received by the detector 31, the detector 31 can realize real-time imaging of the internal structure of the material. Subsequently, the existing image recognition technology, machine vision or deep learning algorithm technology can be used to automatically determine whether there are defects such as sand holes inside the material and the type and level of the defects. Compared with traditional manual visual inspection or camera appearance inspection, the middle frame sand hole X-ray inspection equipment of the present application can non-destructively detect internal defects of materials, and can realize automatic loading and unloading, with high detection efficiency and accuracy.

[0051] See also Figure 1 Optionally, in one embodiment, the middle frame sand hole X-ray detection device further includes a shielding room 40 capable of isolating the detection rays, and the carrying mechanism 10, the ray generating mechanism 20, and the ray receiving mechanism 30 are all arranged in the shielding room 40. The detection rays can be isolated by the shielding room 40, thereby avoiding radiation damage to the on-site workers caused by the detection rays. Exemplarily, in one embodiment, the shielding room 40 can be a lead room, and the lead material has a good isolation effect on detection rays such as X-rays.

[0052] Furthermore, the shielding room 40 is provided with an entrance and exit 41 for the carrier 11 to enter and exit, and an openable and closable shielding door 42 is provided at the entrance and exit 41, and the loading station is arranged on the outside of the shielding door 42, and the detection station is arranged on the inside of the shielding door 42. In this way, when loading is required, the shielding door 42 is opened, and the first driving component 12 pushes the carrier 11 from the entrance and exit 41 to the loading station. After the material is placed on the carrier 11, the carrier 11 is retracted to the detection station in the shielding room 40, and finally the shielding door 42 is closed, thereby realizing automatic loading. Furthermore, the shielding door 42 is electrically connected to the radiation source mechanism 21. When the shielding door 42 is not in a closed state to close the entrance and exit 41, the radiation source mechanism 21 stops running, thereby preventing radiation from leaking from the entrance and exit 41 and endangering the staff. Exemplarily, the shielding door 42 can be a lifting door.

[0053] Optionally, in one embodiment, a detection grating 44 is further provided at the loading station, and the detection grating 44 is electrically connected to the shielding door 42, and the detection grating 44 is used to detect whether a target object enters the loading station, and to stop the shielding door 42 from moving when the target object enters the loading station. The target object includes but is not limited to foreign bodies such as human hands, rods, and plates, so that the shielding door 42 is prevented from being blocked by foreign objects during movement, and the workers are prevented from being pinched by the shielding door 42.

[0054] Exemplarily, the loading station is provided with a loading platform 43, and the loading platform 43 is provided with a groove 431 for accommodating the supporting platform 11, the groove 431 is connected with the inlet and outlet 41, and the detection grating 44 is arranged on the side wall of the groove 431, so that when a hand or other object enters the groove 431, the detection grating 44 is blocked, and the detection grating 44 can detect that an object has entered the groove 431 and send a stop closing signal. The shielding door 42 stops after receiving the stop closing signal, thereby realizing the anti-pinch function.

[0055] See also Figure 4 as well as Figure 5 In one embodiment, the first driving assembly 12 may include two first linear modules 121, the two first linear modules 121 are arranged at intervals along the second direction, and each linear module extends along the first direction. Both sides of the support platform 11 are connected to the corresponding first linear modules 121 through the first connecting plates 122, so as to realize driving the support platform 11 to move stably along the first direction.

[0056] See also Figure 5Optionally, in one embodiment, the support platform 11 includes a mounting base plate 111 and a support assembly. The mounting base plate 111 is connected to the first drive assembly 12, and the mounting base plate 111 is provided with a hollow opening (not shown). Exemplarily, both sides of the mounting base plate 111 are respectively connected to the first drive assembly 12 through the first connecting plate 122, thereby ensuring the installation stability of the mounting base plate 111 and the first drive assembly 12.

[0057] Furthermore, the bearing assembly includes a bearing plate 112 and a side plate 113. The bearing plate 112 is arranged opposite to the hollow opening, and the bearing plate 112 is used to bear materials and can be penetrated by the detection rays. This ensures that the bearing plate 112 can bear materials while avoiding the bearing plate 112 and the mounting base plate 111 from blocking the detection rays, thereby ensuring the clarity of the imaging. Exemplarily, the bearing plate 112 can be made of carbon fiber material, which has the characteristics of high strength, light weight and good radiation penetration, and can meet the requirements of bearing materials and being penetrated by detection rays.

[0058] Furthermore, the side plate 113 is connected to the side of the carrier plate 112 and is detachably connected to the mounting base plate 111. In this way, the carrier assembly can be removed from the mounting base plate 111 as a whole. When loading materials, multiple materials can be loaded onto the carrier assembly first, and then the carrier assembly can be installed on the mounting base plate 111. Similarly, when unloading materials, multiple materials after inspection can also be removed from the mounting base plate 111 as a whole together with the carrier assembly, thereby improving the efficiency of loading and unloading materials.

[0059] Continue to see Figure 5 Optionally, in one embodiment, the mounting base plate 111 is provided with a first positioning pin 114, and the side plate 113 is provided with a positioning hole (not shown), and the first positioning pin 114 is inserted into the positioning hole, thereby ensuring the stability of the bearing assembly after being installed on the mounting base plate 111, and avoiding displacement and misalignment of the bearing assembly during the movement of the bearing platform 11.

[0060] Optionally, in one embodiment, the mounting base plate 111 is provided with a first magnetic member (not shown), the side plate 113 is provided with a second magnetic member 115, and the first magnetic member and the second magnetic member 115 are arranged to attract each other. This improves the connection stability between the bearing assembly and the mounting base plate 111 on the one hand, and on the other hand, when the first magnetic member and the second magnetic member 115 attract each other, they can give the operator good positive feedback to remind the operator that the bearing assembly has been installed in place.

[0061] Optionally, in one embodiment, the mounting base plate 111 is further provided with a first sensor 116, and the first sensor 116 is used to detect whether there is a bearing assembly on the mounting base plate 111. Specifically, when the bearing assembly is installed in place, the first sensor 116 is blocked by the bearing assembly, thereby sensing that the bearing assembly has been installed in place, thereby triggering the first driving assembly 12, the ray generating mechanism 20, and the ray receiving mechanism 30 to perform subsequent operations.

[0062] See also Figure 5 In one embodiment, a plurality of detection positions for placing materials are provided on the carrier plate 112, so that the carrier plate 112 can carry a plurality of materials at the same time, and a plurality of materials can be transported to the detection positions in one loading operation.

[0063] Furthermore, each detection position is provided with a second positioning pin 117 for fixing the material, so as to prevent the material from being displaced or falling during the detection process. Exemplarily, each detection position is provided with a plurality of second positioning pins 117, and the plurality of second positioning pins 117 are together enclosed to form a limited space for accommodating the material. When loading the material, the material can be placed in the limited space to fix the material.

[0064] Optionally, in one embodiment, each detection position is provided with a second sensor (not shown), and the second sensor is used to detect whether there is material on the detection position. Specifically, when the material is placed at the detection position, the second sensor is blocked and thus senses the presence of the material, thereby ensuring that the material is accurately placed in place.

[0065] See also Figure 6 as well as Figure 7 The second driving component 22 may include a second linear module 221 and a third linear module 222. The second linear module 221 extends along the second direction, and the third linear module 222 extends along the third direction. The third linear module 222 is installed on the second linear module 221 through a second connecting plate 231, and the radiation source 21 is installed on the third linear module 222 through a third connecting plate 232. In this way, the radiation source 21 can be driven to move along the second direction and the third direction through the linkage between the second linear module 221 and the third linear module 222, thereby ensuring that the radiation source 21 is aligned with the material to be detected.

[0066] See also Figure 8 as well as Fig. 9The third driving assembly 32 may include a fourth linear module 321 and a fifth linear module 322. The fourth linear module 321 extends along the second direction, and the fifth linear module 322 extends along the third direction. The fifth linear module 322 is installed on the fourth linear module 321 through the fourth connecting plate 331, and the detector 31 is installed on the fifth linear module 322 through the fifth connecting plate 332. In this way, the detector 31 can be driven to move along the second direction and the third direction through the linkage between the fourth linear module 321 and the fifth linear module 322, thereby ensuring that the detector 31 is aligned with the material to be detected.

[0067] On the other hand, the present application also provides a middle frame sand hole X-ray detection method for detecting defects such as sand holes inside materials. The materials include but are not limited to castings such as mobile phone middle frames. Specifically, the middle frame sand hole X-ray detection method of one embodiment includes the following steps:

[0068] S110: The first driving assembly 12 drives the carrying platform 11 to the loading station so that the carrying platform 11 receives the material to be inspected;

[0069] S120: The first driving assembly 12 drives the carrying platform 11 to the inspection station;

[0070] S130: the second driving assembly 22 moves the radiation source 21 to a side opposite to the material, and emits detection radiation to the material;

[0071] S140: The third driving component 32 moves the detector 31 to be opposite to the other side of the material, and receives the detection rays passing through the material to output a detection image.

[0072] Specifically, after the detection image is output, the existing image recognition technology, machine vision technology or deep learning algorithm technology can be used to automatically determine whether there are defects such as sand holes inside the material and the type and level of the defects. Compared with traditional manual naked eye detection or camera appearance detection, the middle frame sand hole X-ray detection equipment of this application can realize the detection of internal defects of materials without damage, and can realize automatic loading and unloading, with high detection efficiency and accuracy.
