DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 6As shown, this utility model provides a novel online X-ray inspection machine, including a worktable 1, a product transfer device 2 arranged on the worktable 1, an X-ray emitting device 5 arranged on the worktable 1 and located below the product transfer device 2, a fixed frame 4 arranged on the worktable 1, and an X-ray receiving device 3 installed on the fixed frame 4 and located above the product transfer device 2. In one embodiment, it also includes a measuring mechanism 6; the measuring mechanism 6 includes a fixed plate 61 connected to one side of the top of the fixed frame 4, a rotary drive mechanism 62 installed on the fixed plate 61, and a rotating arm 63 connected at one end to the rotary drive mechanism 62; the rotating arm 63 is located above the product transfer device 2, and the other end of the rotating arm 63 is also connected to a connecting plate 64; a detection camera assembly and a height displacement meter are also installed on one side of the connecting plate 64.

[0024] In this embodiment, a fixing plate 61 is connected to one side of the top of the fixing frame 4. A freely rotatable rotating arm 63 is provided on the fixing plate 61. The detection camera assembly and the height displacement meter are mounted on the rotating arm 63. When the detection camera assembly and the height displacement meter are working, the rotating arm 63 can be driven to rotate counterclockwise by the rotation drive mechanism 62 (e.g., Figure 1 As shown, the product transfer device 2 rotates upwards by a certain angle (the rotation angle is preset to 45°, but can be adjusted according to actual use), causing the detection camera assembly and height displacement meter to rotate to the center area of ​​the product transfer device 2. Then, the product transfer device 2 (including the XY axis translation mechanism and the product-carrying platform, which can use existing mechanisms without limitation) moves the platform to cooperate with the detection camera assembly and height displacement meter to complete the measurement. While the x-ray emitting device 5 and x-ray receiving device 3 (including the XY axis translation mechanism and the flat panel detector, which can use existing devices without limitation) are working, the rotation drive mechanism 62 drives the rotating arm 63 to rotate clockwise by a certain angle, causing the rotating arm 63 to rotate to a position parallel to the X direction of the product transfer device 2, forming a clearance (such as...). Figure 1 As shown, this design avoids the movement range of the x-ray receiving device 3 in the XY direction and also prevents it from being directly irradiated by the x-ray emitter 55 below. This increases the service life of the inspection camera assembly and the height displacement meter, reduces costs, and, since the inspection camera assembly and the height displacement meter are mounted on the rotating arm 63, the weight and space occupied by the XY axis translation mechanism head can be reduced, thereby improving inspection speed and making it highly practical.

[0025] In one embodiment, a protective shell 65 is also connected to one side of the connecting plate 64, and the protective shell 65 has a first cavity with an opening at its bottom; the detection camera assembly and the height displacement meter are located in the first cavity; the detection camera assembly includes a first mounting plate 66 connected to the upper part of one side of the connecting plate 64, a CCD camera 67 mounted on the first mounting plate 66, a second mounting plate 68 connected to the lower part of one side of the connecting plate 64, and a ring light source 69 mounted on the second mounting plate 68 and located below the CCD camera 67. The protective shell 65 encloses the detection camera assembly and the height displacement meter, preventing damage from impacts without affecting their normal operation and improving their safety. Meanwhile, the rotary drive mechanism 62 includes a rotary motor, a reducer connected to the rotary motor, and a rotary table connected to the reducer; one end of the rotating arm 63 is connected to the rotary table. The combination of a motor and a reducer improves the rotational stability of the rotating arm 63.

[0026] In one embodiment, the x-ray emitting device 5 includes two first supports 51, a first translation frame 52, a first translation seat 53, a first lifting seat 54, and an x-ray emitter 55; the two first supports 51 are arranged parallel and spaced apart on the worktable 1, and a Y-axis slide rail assembly 511 is installed on the top of each first support 51; a Y-axis translation drive mechanism 512 is installed on one side of each first support 51; the bottom ends of the first translation frame 52 are slidably arranged on a Y-axis slide rail assembly 511, and the two ends of the first translation frame 52 are respectively connected to a Y-axis translation drive mechanism 512; a first sliding groove is formed on the top of the first translation frame 52 along its length direction, and the first translation frame... An X-axis slide rail assembly 521 is arranged on each of the top two sides of the first translation frame 52; a first sliding seat 531 is connected to each of the two sides of the first translation seat 53, and each first sliding seat 531 is slidably arranged on an X-axis slide rail assembly 521; an X-axis translation drive mechanism 532 is installed on each of the two sides of the first translation frame 52, and the two X-axis translation drive mechanisms 532 are respectively connected to a first sliding seat 531; a lifting slide rail assembly is also arranged on the first translation seat 53 along the vertical direction, and a first lifting seat 54 is slidably arranged on the lifting slide rail assembly; the X-ray emitter 55 is installed on the first lifting seat 54, and a lifting drive mechanism 56 connected to the first lifting seat 54 is also installed on the first translation seat 53.

[0027] In this embodiment, the Y-axis translation drive mechanism 512 and the X-axis translation drive mechanism 532 can use existing translation motors, and there are no restrictions on this. The two ends of the first translation frame 52 are respectively arranged on a Y-axis slide rail assembly 511, which can support the bottom ends of the first translation frame 52 with uniform support force, ensuring the stability of the translation of the first translation frame 52. Simultaneously, each of the top ends of each first support 51 is connected to a first limiting block, and a first buffer stop is also installed on one side of the first limiting block, which can limit the movement stroke of the first translation frame 52. Limiting the movement of the first translation seat 53 improves its safety. Each side of the first translation seat 53 is connected to an X-axis slide rail assembly 521 via a first sliding seat 531, which ensures the stability of the translation of the first translation seat 53. At the same time, the two ends of the inner walls on both sides of the first slide groove are equipped with second buffer blocks, which can limit the movement of the first translation seat 53 and improve its safety. The lifting drive mechanism 56 can drive the first lifting seat 54 to rise and fall, thereby adjusting the distance between the x-ray transmitter 55 and the x-ray receiver to achieve detection at different magnifications.

Meanwhile, a reinforcing bracket is connected to each side of the top of the L-shaped horizontal end of the first lifting seat 54, and one end of the reinforcing bracket is connected to one side of the L-shaped vertical end of the first lifting seat 54; the x-ray emitter 55 is located between the two reinforcing brackets. A reinforcing bracket is provided to improve the rigidity of the first lifting seat 54 structure. The lifting drive mechanism 56 includes a lifting drive motor 561 mounted on one side of the first translation seat 53, a drive wheel 562 mounted on the output shaft of the lifting drive motor 561, a lifting screw 563 arranged on the inner wall of one side of the first mounting groove, a driven wheel 564 mounted on one end of the lifting screw 563, and a synchronous belt 565 wound between the drive wheel 562 and the driven wheel 564. A screw nut is also mounted on the lifting screw 563, and the L-shaped vertical end of the first lifting seat 54 is connected to the screw nut. The use of a motor in conjunction with the synchronous wheel, synchronous belt 565, and screw transmission improves the stability of the lifting of the first lifting seat 54.
