Description

Technical Field

[0001] The utility model relates to the technical field of X-ray detection, in particular to a rotation detection device for X-ray equipment. Background Art

[0002] X-ray inspection equipment can be used for non-destructive testing of internal defects in electronic components and chips. It can view the wafers, gold wires, and welding conditions inside electronic components and chips through X-ray perspective, and analyze internal fault points in a timely manner.

[0003] Currently, most X-ray inspection equipment does not have a multi-angle rotation function, which limits the fluoroscopic operation. During the inspection process, the device needs to be shut down and adjusted back and forth to adjust the angle of the electronic components and chips before it can be turned on to continue the fluoroscopic inspection. Frequent starting and stopping of the X-ray tube of the X-ray inspection equipment can easily affect its service life, and each angle adjustment is time-consuming and labor-intensive. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an X-ray equipment rotation detection device, which automatically rotates the angle of the material plate to achieve adjustment of various angles of chips and components on the material plate. There is no need to manually stop the machine to adjust the angles of chips and electronic components back and forth, which saves time and effort and solves the problem of frequent start and stop of X-ray equipment affecting its service life.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a rotation detection device for X-ray equipment, comprising a first driving member, a second driving member and a support arm, the second driving member and a material plate are installed on the support arm, the second driving member is connected to the material plate, the first driving member is connected to the support arm, the rotation axis of the support arm and the rotation axis of the material plate are perpendicular to each other, and the first driving member and the second driving member are respectively connected to a PLC controller.

[0006] Furthermore, the material plate is provided with at least one of a negative pressure adsorption plate, a sponge area and a foam area.

[0007] On the one hand, the support arm fixes the material plate, and on the other hand, it rotates around the first axis under the driving action of the first driving member, thereby driving the material plate to rotate. The material plate is placed and fixed with materials such as chips and electronic components to be tested. The material plate is driven to rotate around the second axis by controlling the second driving member. The rotation axis of the support arm is perpendicular to the rotation axis of the material plate, that is, the first axis direction is perpendicular to the second axis direction, exemplified by the X-axis and Y-axis. Therefore, after the X-ray equipment is started, it can realize perspective detection of chips and components at various angles.

[0008] As a further improvement of the present invention: the first driving component is a servo motor, and the second driving component is a stepping motor.

[0009] As a further improvement of the utility model: it also includes a mobile structure, and the mobile structure is equipped with a material taking mechanism and a camera.

[0010] As a further improvement of the utility model: it also includes a material storage platform, and the material storage platform includes a storage slot area and a negative pressure adsorption area.

[0011] The storage slot area is provided with a plurality of storage card slots for placing chips and electronic components to be tested. Generally, the storage card slots are used for placing chips and electronic components with pins. The chips and electronic components with pins are fixed by using the recessed limit of the card slots, with the pins placed toward the inside of the storage card slots, and the relatively flat side of the chips and electronic components facing the movable structure.

[0012] The negative pressure adsorption area has multiple adsorption ports, and adopts the negative pressure adsorption principle to fix chips and electronic components. Generally, the negative pressure adsorption area is used to place pinless chips and electronic components, and the adsorption and fixation stability is good.

[0013] Of course, chips and electronic components with pins can also be placed in the negative pressure adsorption area for limit fixing. Due to the pin characteristics, the negative pressure adsorption effect is inferior to the recessed limit effect of the storage slot.

[0014] As a further improvement of the utility model: it also includes a remote controller, the camera and the PLC controller are respectively connected to the remote controller for communication, and the remote controller is provided with a display screen and control buttons.

[0015] The remote controller may be a remote wireless controller, which generally includes a wireless signal transceiver, a remote processing computer, a display screen, etc. The wireless signal transceiver may be an antenna, a Bluetooth component, a wireless Wifi component, etc. The control button may be a key-type button or a virtual key-type button. For example, a touch button is provided on the display screen.

[0016] As a further improvement of the present utility model: the material storage platform is installed on a fixing frame, and a limiting mechanism is provided on the fixing frame, and the limiting mechanism is used to fix the material storage platform.

[0017] A limit area is provided on the material storage platform, and the limit mechanism is provided with a cylinder and a limit block. The telescopic rod of the cylinder is fixedly connected to the limit block. The limit block is extended and fixed in the limit area by utilizing the telescopic action of the cylinder to limit and fix the material storage platform. After the test is completed, the limit block is retracted and separated from the material storage platform. The operator removes the material storage platform and re-places new chips and electronic components to be tested.

[0018] As a further improvement of the present invention: An angle measuring device is installed on both the first driving member and the second driving member, and the angle measuring device is connected to the PLC controller.

[0019] As a further improvement of the present invention: the angle measuring device is an angle sensor or an angle encoder.

[0020] The angle measuring device is used to measure the rotation angles of the first driving member and the second driving member, and the angular coordinates of the chips and electronic components on the material board are correspondingly determined. In conjunction with the perspective image of the X-ray equipment, the PLC controller automatically records the perspective images corresponding to different angle coordinate positions, which is convenient for product traceability analysis.

[0021] As a further improvement of the utility model: the material taking mechanism is any one of a suction cup, a clamping claw, and a manipulator.

[0022] As a further improvement of the present invention: the mobile structure is a robot or a three-coordinate operating mechanism, and the three-coordinate operating mechanism includes an X-axis mobile module, a Y-axis mobile module and a Z-axis mobile module.

[0023] When the X-gate equipment tests chips and electronic components on site, the material to be tested is moved to the material plate for fixing, and the placement coordinates and placement images of the material to be tested are recorded;

[0024] Start the X-ray tube of the X-ray device, control the first driving member and the second driving member to start, and adjust the angle of the material plate and the material to be tested thereon;

[0025] Automatically obtain perspective images of the material to be tested from multiple angles;

[0026] Determine whether the material to be tested is qualified based on perspective images from multiple angles;

[0027] If it fails, the angle coordinates of the failed material will be automatically recorded.

[0028] As a further improvement of the utility model: it also includes:

[0029] Obtaining an initial image and a first coordinate position of the material, wherein the initial image is not an image after being viewed through an X-ray device, but an image taken by a camera when the material is placed on a material storage platform;

[0030] Determining a placement area for a material according to the initial image;

[0031] The placement area of ​​the material on the material board is manually determined based on the initial image or the system automatically determines that there are pinned chips and electronic components and there are no pinned chips and electronic components.

[0032] The system can determine the type of material based on the material shape in the initial image. The material types are mainly divided into pinned chips, electronic components and pinless chips, electronic components. The system can also determine the type of material based on the first coordinate position of the initial image or the storage area on the material storage receipt. There is a clear difference between the images of the storage slot area and the negative pressure adsorption area, which can achieve simple and quick judgment.

[0033] After the material is moved to the material board, the camera automatically captures the placement image of the material and synchronizes the corresponding coordinate position data according to the moving structure. At the same time, the remaining coordinate positions on the material board are automatically updated. Therefore, after determining the material placement area, the second coordinate position of the material is also automatically determined.

[0034] Compared with the prior art, the beneficial effects of the utility model are:

[0035] The utility model sets the angle of the first driving member to rotate the support arm, the material plate is installed on the support arm, and the angle of the second driving member to rotate the material plate is set, so that the rotation axis of the support arm and the rotation axis of the material plate are perpendicular to each other, thereby realizing multi-angle rotation of the material plate and the material placed on the material plate, automatically recording the perspective images of the chip at different angles, and there is no need to manually start and stop the X-ray equipment to adjust the perspective angle of the chip, thus saving time and effort and avoiding frequent starting and stopping of the X-ray light tube to affect the service life.

[0044] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] In order to solve the technical problems that the X-ray detection equipment in the prior art has its own fixed stage, the angles of chips and electronic components need to be manually adjusted during the detection process, which is time-consuming and labor-intensive, and the frequent start and stop of the X-ray tube seriously affects the service life, the utility model is further described in combination with the accompanying drawings and embodiments:

[0046] like Figure 1-Figure 6 As shown, the utility model discloses a rotation detection device for an X-ray device 1, comprising a first driving member 2, a second driving member 3 and a support arm 4, the second driving member 3 and a material plate 5 are mounted on the support arm 4, the second driving member 3 is connected to the material plate 5, the first driving member 2 is connected to the support arm 4, and the rotation axis of the support arm 4 and the rotation axis of the material plate 5 are perpendicular to each other.

[0047] The first driving member 2 and the second driving member 3 function to provide driving force. The first driving member 2 drives the support arm 4 to rotate, and the second driving member 3 drives the material plate 5 to rotate. The material plate 5 is installed on the support arm 4, and the material placed on the material plate 5 can be rotated at multiple angles, and cooperated with the X-ray equipment 1 to complete multiple-angle perspective detection of the material.

[0048] As a preferred embodiment, the first driving member 2 and the second driving member 3 are both installed with an angle measuring device, and the angle measuring device, the first driving member 2 and the second driving member 3 are respectively connected to the PLC controller 6 .

[0049] like Figure 4As shown, the rotating detection device of the X-ray equipment 1 is installed inside the X-ray equipment 1. Specifically, the rotating device composed of the first driving member 2, the second driving member 3, the support arm 4 and the material plate 5 is located in the irradiation area of ​​the X-ray tube of the X-ray equipment 1, so that the X-ray detection of chips and electronic components on the material plate 5 can be realized.

[0050] Since the X-ray device 1 has a large radiation, the operating table is generally far away from the device, and it is troublesome to manually adjust the angle back and forth. Through the mutual cooperation between the first drive member 2, the second drive member 3 and the support arm 4, there is no need to manually adjust the angle of the chip and electronic components back and forth, nor is there any need to frequently start and stop the X-ray device 1, which avoids affecting the service life and saves time and effort.

[0051] In addition, the rotation angles of the first driving member 2 and the second driving member 3 are measured by an angle measuring device, and the PLC controller 6 receives the angle data of the angle measuring device to determine the angular coordinate positions of the material board 5 and the chips and electronic components thereon. The X-ray device 1 operates to take perspective images of chips and electronic components at various angles, and simultaneously uploads them to the remote controller 11 or other terminals that can display and view them. The perspective images are automatically associated with the bound angular coordinate information to facilitate subsequent traceability analysis of the tested product.

[0052] As a preferred embodiment, the first driving member 2 and the second driving member 3 can be motors, the output shaft of the first driving member 2 is connected to the support arm 4 , and the output shaft of the second driving member 3 is connected to the material plate 5 .

[0053] Regarding the selection of motor type, the second driving member 3 is installed on the support arm 4 and only drives the material plate 5 to rotate. You can consider selecting a stepper motor with general overload capacity and a small torque range; the first driving member 2 drives the support arm 4, material plate 5 and second driving member 3 and other structures to rotate together. You can consider selecting a servo motor with strong overload capacity, good acceleration performance and smooth operation.

[0054] The first drive member 2 and the second drive member 3 may also both use servo motors, monitor the feedback signal in real time to adjust the error, achieve high-precision position, speed and torque control, and improve the stability of the rotation process of the support arm 4 and the material plate 5. The first drive member 2 and the second drive member 3 may also both use stepper motors, and the overall control performance is not as good as that of using servo motors.

[0055] As a preferred embodiment, a mounting frame 51 is installed on the support arm 4 , and the mounting frame 51 fixes the material plate 5 , and the second driving member 3 is connected to the mounting frame 51 to ensure that the material plate 5 rotates smoothly under the drive of the second driving member 3 .

[0056] More preferably, the material plate 5, the support arm 4 and the mounting frame 51 are all made of plastic material, which will not affect the X-ray.

[0057] More preferably, one side of the mounting frame 51 is connected to the second driving member 3, a bearing 52 hole is opened on the support arm 4, a bearing 52 is installed in the bearing 52 hole, and the other side of the mounting frame 51 is connected to the bearing 52, ensuring that when the mounting frame 51 is driven by the second driving member 3, the material board 5 and the chips and electronic components thereon rotate smoothly.

[0058] As a preferred embodiment, it also includes a mobile structure 7 and a material storage platform 8. The mobile structure 7 is equipped with a material taking mechanism and a camera 9. The material storage platform 8 includes a storage slot area 81 and a negative pressure adsorption area 82.

[0059] The material storage platform 8 is used to temporarily store chips and components to be tested. There is no specific restriction on the quantity and type of chips and components. The camera 9 is used to photograph the chips and electronic components on the material storage platform 8 for subsequent operations.

[0060] The mobile structure 7 cooperates with the material picking mechanism, and the material picking mechanism takes away the chips and components on the material storage platform 8. The mobile structure 7 drives the material picking mechanism to move, and the chips and components on the material storage platform 8 are placed on the material plate 5 and fixed. The mobile structure 7 then resets to the origin and waits for the X-ray equipment 1 to complete the perspective detection work.

[0061] The utility model utilizes the mobile structure 7 to complete multiple material handling, which is convenient for the subsequent X-ray device 1 to detect the internal conditions of the materials and improves the testing efficiency.

[0062] After the operator puts the chips and components into the material storage platform 8, the material storage platform 8 is placed inside the X-ray device 1, the safety door 101 of the X-ray device 1 is closed, and the operator moves to the safety control area. The camera 9 takes images of all chips and electronic components, selects one or more images, controls the moving structure 7 and the material taking mechanism, moves the chips and electronic components corresponding to the selected images to the corresponding area of ​​the material board 5 for fixing, and finally cooperates with the rotation of the first driving member 2, the second driving member 3, the material board 5 and the support arm 4 to achieve multi-angle perspective detection of various chips and components.

[0063] Therefore, the X-ray device 1 can complete the X-ray detection of multiple chips and components by starting it once, reducing the number of starts and stops of the X-ray tube of the X-ray device 1, which will not seriously affect the service life of the equipment, and the number of round trips of the operator is reduced, thereby correspondingly improving the detection efficiency.

[0064] As a preferred embodiment, Figure 5As shown, the storage slot area 81 is provided with a plurality of storage slots, and the recessed depth, shape and size of the storage slots are specifically designed according to the shapes of chips and electronic components.

[0065] For example, when a chip or electronic component with pins is placed in the storage slot, the pins of the electronic component or chip are placed in the recessed area of ​​the storage slot so that the relatively flat side faces upward, which plays a certain role in limiting and fixing, making placement simple and fast and easy to operate.

[0066] For example, when a chip or electronic component without pins is placed in the storage slot, the recessed area of ​​the storage slot is arranged to be stepped, and the inner side of the storage slot extends along the circumferential direction to form a fixed step. The fixed step and the upper opening of the storage slot form a limiting space, and the fixed step plays a role in receiving and positioning the chip or component without pins.

[0067] As a preferred embodiment, the negative pressure adsorption area 82 is provided with a plurality of adsorption ports, which are connected to the negative pressure generator 14 via a connecting tube, and the negative pressure adsorption principle is utilized to complete the adsorption and fixation of chips and electronic components. It should be noted that the connection between the connecting tube, the adsorption port and the negative pressure generator 14 is a prior art and will not be elaborated in detail in the present utility model.

[0068] In the above example, the negative pressure adsorption area 82 can be used to adsorb and fix chips without pins and electronic components, and can also be used to adsorb and fix chips with pins and electronic components. Generally, the negative pressure adsorption area 82 is more effective in fixing chips without pins and electronic components.

[0069] In addition, in addition to using the storage slot area 81 and the negative pressure adsorption area 82 to fix chips and electronic components, the material storage platform 8 can also be provided with other fixing structures. For example, chips and electronic components with pins can be fixed by using structures such as sponges and foams, and the pin parts can be inserted into the sponges and foams to achieve the positioning of the chips and electronic components.

[0070] The storage slot area 81 and the negative pressure adsorption area 82 provided in the present invention can realize universal design and are suitable for testing chips and electronic components of different specifications and types.

[0071] As a preferred embodiment, Figure 6 As shown, a remote controller 11 is also included. The camera 9 and the PLC controller 6 are respectively connected to the remote controller 11 for communication. The remote controller 11 is provided with a display screen 111 and a control button 112. The remote controller 11 is also connected to the X-ray device 1 for communication.

[0072] The display screen 111 is used to display the placement images of chips and electronic components taken by the camera 9, and is also used to display the perspective images of chips and electronic components taken by the X-ray device 1. The control buttons 112 include buttons with the function of selecting the images of chips and electronic components in the display screen 111, buttons with the function of controlling the rotation of the first driving member 2 and the second driving member 3, buttons with the function of controlling the start and stop of the X-ray device 1, upload and save buttons, confirmation buttons, etc.

[0073] The remote controller 11 includes a controller using a remote wireless transmission mode, a Bluetooth transmission mode, or a wireless Wifi transmission mode. Specifically, the remote control mode is a prior art. The remote controller 11 may be a remote wireless controller. The remote controller 11 generally includes a wireless signal transceiver, a remote processing computer, a display screen 111, and other structures. The wireless signal transceiver may select an antenna 13, a Bluetooth component, a wireless Wifi component, and the like.

[0074] The remote controller 11 of the utility model communicates with the PLC controller 6 in real time, remotely controls the actions of the first driving member 2 and the second driving member 3, thereby adjusting the angle of the material plate 5 and the chips and electronic components thereon, replacing manual adjustment of the material angle, and cooperating with the angle measurer to record the angle in real time. The remote controller 11 also communicates with the X-ray device 1 in real time, reads the shooting data of the X-ray device 1, and records the perspective images of the chips and electronic components at different angle coordinate positions in real time.

[0075] In addition, the perspective image and angle coordinate data can be bound and uploaded to the MES platform for later material analysis, product traceability testing, and angular coordinates corresponding to defects in chips and components.

[0076] As a preferred embodiment, the material plate 5 is provided with at least one of a negative pressure adsorption plate 501 , a sponge area and a foam area 502 .

[0077] The negative pressure adsorption plate 501 adopts the negative pressure adsorption principle, and its main structure includes a negative pressure generator 14, a connecting pipe and adsorption holes, etc. The structures of the negative pressure adsorption plate 501 and the negative pressure adsorption area 82 on the material storage platform 8 are not much different.

[0078] The sponge area refers to an area formed by setting a sponge material on the material plate 5 . Similarly, the foam area 502 refers to an area formed by setting a foam material on the material plate 5 .

[0079] For example, the sponge area uses EPE, also known as pearl sponge. Polyethylene foam is a non-cross-linked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene resin. It overcomes the shortcomings of ordinary foam rubber, such as fragility, deformation, and poor resilience. It has many advantages such as waterproof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance. The chip pin can be directly inserted into the pearl sponge to achieve fixation.

[0080] During actual testing, a suitable placement area is selected from the negative pressure adsorption plate 501, the foam area 502 and the sponge area according to the structural characteristics of the chip or electronic components to be tested.

[0081] For example, only a negative pressure adsorption plate 501 is provided on the material plate 5, which is suitable for testing chips with and without pins, and electronic components, and realizes the versatility of rapid placement of materials. However, the stability of chips with pins and electronic components using negative pressure adsorption is poor, and the fixing effect is better using a sponge area or a foam area 502.

[0082] For example, only a sponge area is provided on the material plate 5, or only a foam area 502 is provided, or both the sponge area and the foam area 502 are provided. This is only used for testing chips and electronic components with pins. The pin part is inserted into the sponge or the foam to fix the chips and electronic components, ensuring that during the process of the first driving member 2 and the second driving member 3 rotating the material plate 5, the chips and electronic components are firmly placed on the material plate 5 and do not fall off.

[0083] For example, the negative pressure adsorption plate 501, the sponge area and the foam area 502 are simultaneously arranged on the material plate 5. The X-ray device 1 can simultaneously test chips and electronic components of various specifications, thereby improving the detection efficiency.

[0084] As a preferred embodiment, the material storage platform 8 is installed on a fixing frame, and a limiting mechanism 12 is provided on the fixing frame. The limiting mechanism 12 is used to fix the material storage platform 8 .

[0085] More preferably, the limiting mechanism 12 is provided with a cylinder 121 and a limiting block 122, the telescopic rod of the cylinder 121 is connected to the limiting block 122, a limiting area is provided on the material storage platform 8, and the limiting block 122 is fixedly connected to the limiting area to fix the material storage platform 8.

[0086] For example, at least two limiting mechanisms 12 are provided on the periphery of the material storage platform 8, and the two limiting mechanisms 12 are symmetrically arranged. Alternatively, a positioning bar is provided on one side of the fixing frame, one side of the material storage platform 8 is fixed to the positioning bar, and a limiting mechanism 12 is provided on the other side of the fixing frame to fix the other side of the material storage platform 8.

[0087] The limiting mechanisms 12 are four in sequence arranged along the four sides of the material storage platform 8 .

[0088] During the operation of the moving structure 7 and taking materials from the material storage platform 8, the material storage platform 8 moves, causing the placed chips and electronic components to shift, which affects the material taking action of the material taking mechanism. The utility model fixes the material storage platform 8 through the limiting mechanism 12 for precise limiting to prevent material shifting during operation.

[0089] As a preferred embodiment, the angle measuring device is an angle sensor or an angle encoder. The angle of rotation of the first driving member 2 and the second driving member 3 is monitored in real time by the angle sensor or the angle encoder, and the angle coordinate position of the material plate 5 is determined by the rotation angle data of the two.

[0090] For example, when the first driving component 2 is a servo motor and the second driving component 3 is a stepping motor, an angle sensor or an angle encoder is installed on the output shaft of the servo motor and the output shaft of the stepping motor to automatically detect the rotation angle of the two output shafts.

[0091] As a preferred embodiment, the material taking mechanism is any one of the suction cup 10, the clamping claw, and the manipulator.

[0092] The suction cup 10 in the utility model is designed based on the vacuum adsorption principle. After the chips and electronic components on the material storage platform 8 are adsorbed by negative pressure, they are transferred to the material plate 5 in cooperation with the mobile structure 7. The clamping claws are flexible based on the characteristics of the chip to avoid damage to the chip. The specific structure and gripping force of the flexible clamping claws and the manipulator belong to the prior art.

[0093] As a preferred embodiment, the mobile structure 7 is a robot or a three-coordinate operating mechanism, and the three-coordinate operating mechanism includes an X-axis moving module, a Y-axis moving module and a Z-axis moving module.

[0094] The robot is a prior art, which can realize the functions of moving and carrying materials. It will not be described in detail in the present invention.

[0095] The three-coordinate operation mechanism drives the material picking mechanism and the material to move along the X-axis direction by setting the X-axis moving module, drives the material picking mechanism and the material to move along the Y-axis direction by setting the Y-axis moving module, and drives the material picking mechanism and the material to move along the Z-axis direction by setting the Z-axis moving module. The X-axis moving module includes an X-axis driving member, a moving table, a slider, a photoelectric switch and other structures, and the Y-axis moving module and the Z-axis moving module are substantially the same as the X-axis moving module, which is the prior art.

[0096] The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other. The X-axis moving module, the Y-axis moving module and the Z-axis moving module cooperate with each other to move the chips and electronic components to the material board 5 through lifting and translation. At the same time, they cooperate with the material picking mechanism to fix the chips and electronic components in the corresponding placement area on the material board 5.

[0097] A test procedure for using a rotation detection device of an X-ray device 1 includes:

[0098] Move the material to be tested to the material plate 5 and fix it, and record the placement coordinates and placement image of the material to be tested;

[0099] Start the X-ray tube of the X-ray device 1, control the first driving member 2 and the second driving member 3 to start, and adjust the angle of the material plate 5 and the material to be tested thereon;

[0100] Automatically obtain perspective images of the material to be measured at multiple angles, and determine the rotation angles of the first driving member 2 and the second driving member 3 according to the measurement data of the angle measuring device;

[0101] The angle coordinates corresponding to the perspective images at different angles are recorded, and the perspective image, angle coordinates, placement coordinates and placement image of the material to be measured are associated and saved.

[0102] During the on-site test, the operator places the chips and electronic components on the material storage platform 8, puts the material storage platform 8 into the fixed frame for fixing, closes the safety door 101 of the X-ray device 1, moves to the safety control area, generally moves to 15 meters away, and starts the X-ray device 1. Then the operator sets the running program through the remote controller 11, debugs the communication data transmission between the mobile structure 7, the material taking mechanism, the first driving member 2, the second driving member 3, the remote controller 11, and the X-ray device 1, and the device automatically resets to the initial position.

[0103] The control moving structure 7 drives the camera 9 and the material taking mechanism to move to the top of the material storage platform 8, and then the camera 9 takes images of all chips, electronic components and other materials on the material storage platform 8, and records the material shape and coordinates, and synchronizes the data and material placement image to the remote control and displays it on the display screen 111, wherein the coordinate data is defined in advance according to the storage card slot, negative pressure adsorption area 82 and the like of the material storage platform 8, and the corresponding coordinates are automatically determined according to the corresponding area of ​​the image after the material image is taken. The coordinate definition principle is the prior art. Automatically obtaining the coordinate data facilitates the subsequent rapid and accurate control of the moving structure 7 to the location of the corresponding chips and electronic components, so that the material taking mechanism can take away the materials.

[0104] The operator selects the image corresponding to the chip or electronic component to be tested through the control button 112 or the touch display screen 111. He can select only one image or multiple material images. After selecting multiple images to be tested, the mobile structure 7 can move all the selected chips and electronic components to the material board 5 at one time, or it can move one selected chip or electronic component and wait for the X-ray equipment 1 to complete the test before moving it again.

[0105] Furthermore, the detection system determines whether the material is a chip or electronic component with or without pins based on the material image, and then moves the material to different placement areas on the material board 5 to subdivide the material placement method.

[0106] For example, when the material is determined to be a chip with pins or electronic components, the moving structure 7 and the material picking mechanism are controlled to move the material to the sponge area or foam area 502. When the material is determined to be a chip without pins or electronic components, the moving structure 7 and the material picking mechanism are controlled to move the material to the negative pressure adsorption area 82.

[0107] After the selected chips and electronic components are moved to the material board 5, the camera 9 is controlled to capture the placement image of the materials on the material board 5, and the displacement coordinates of the moving structure 7 are automatically recorded. The displacement structure is reset to the initial position, the X-ray tube of the X-ray device 1 is started, and the first drive and the second drive 3 are controlled to operate. The angle of the material board 5 is rotated to start the perspective test, and the perspective images of chips and electronic components at different angles are automatically obtained. The angular coordinate data corresponding to the rotation angle of the first drive 2 and the second drive 3 are determined. The placement image and the perspective image on the material board 5 are automatically associated and bound with the corresponding angular coordinate data, which is convenient for subsequent testing and traceability of the tested products.

[0108] Further testing steps for determining material eligibility include:

[0109] Determine whether the material to be tested is qualified based on perspective images from multiple angles;

[0110] If it fails, the angle coordinates of the failed material will be automatically recorded.

[0111] The utility model can automatically determine whether there are defects in the perspective images of chips and electronic components at different angles through the material qualification determination system, and then determine whether they are qualified.

[0112] Of course, the first driving member 2 and the second driving member 3 are running to adjust the angles of the chips and electronic components, and the X-ray device 1 sees through the chips and electronic components, and synchronizes the perspective images of the chips and electronic components at different angles to the remote controller 11 in real time, and displays them on the display screen 111, manually determining whether the material to be tested has defects, confirming the existence of defects inside the material, and recording the angle coordinate data and perspective images corresponding to the defects, and uploading them to the MES system for storage after the test is completed.

[0113] The above description is only a specific embodiment of the utility model, so that those skilled in the art can understand or implement the utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features applied herein.
