Description

Technical Field

[0001] This invention belongs to the field of X-ray inspection equipment technology, and in particular relates to a multi-station sphere conveying device and X-ray inspection equipment. Background Technology

[0002] The existing small ball inspection process involves the small ball passing through a pipe and a transmission mechanism into a belt conveyor, and then being transported by the belt conveyor to a single-station disc inspection area for inspection. This existing technology has the following drawbacks: 1. The transmission mechanism is relatively complex, with the small ball passing through multiple mechanisms, requiring high stability from each piece of equipment; 2. Because the material density of the overlapping area with the small ball needs to be significantly lower than the density of the small ball during X-ray inspection, and there are also thickness requirements, the design requirements for the mechanism are high, increasing the design difficulty; 3. The single-station inspection mechanism has low inspection efficiency. Summary of the Invention

[0003] In view of this, the present invention aims to propose a multi-station ball conveying device to solve the problem that the existing conveying equipment has a complex structure and can only transmit at a single station, resulting in low work efficiency.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A multi-station ball conveying device includes a conveying pipe and a feed inlet, a counting sensor, a limiting storage mechanism, and multiple detection and limiting mechanisms arranged sequentially from the feed end to the discharge end. The counting sensor, the limiting storage mechanism, and the multiple detection and limiting mechanisms are respectively connected to a controller. The conveying pipe is also provided with a dust suction interface and several pipe blowing interfaces. The dust suction interface, the pipe blowing interfaces, and the conveying pipe form a dust removal channel.

[0006] Furthermore, the detection limiting mechanism includes a rotary cylinder and a limiting plate. The conveying pipe is provided with an arc-shaped groove for placing the limiting plate. The fixed end of the rotary cylinder is fixed to the outside of the conveying pipe, and the rotating shaft is connected to the limiting plate, so that when the rotary cylinder works, it can drive the limiting plate to rotate. When the limiting plate is located in the arc-shaped groove, it can prevent the ball in the conveying pipe from passing through. The rotary cylinder signal is connected to the controller.

[0007] Furthermore, the limiting material storage mechanism includes a dual-axis cylinder and a baffle. The conveying pipe is provided with a groove for inserting the baffle. The dual-axis cylinder is signal-connected to the controller. The fixed end of the dual-axis cylinder is fixedly connected to the conveying pipe, and the movable end is fixedly connected to the baffle, so that when the dual-axis cylinder is working, it can drive the baffle to enter or leave the inside of the conveying pipe.

[0008] Furthermore, the conveying pipe is composed of multiple conveying single pipes connected in sequence and fixedly connected, and the conveying single pipes are straight pipes or bends.

[0009] Furthermore, the feed inlet is funnel-shaped or horn-shaped.

[0010] Compared with existing technologies, the multi-station ball conveying device of the present invention has the following advantages:

[0011] (1) The multi-station ball conveying device of the present invention can convey the ball to the detection position through a relatively simple conveying method, which reduces the design difficulty and cost, while increasing the detection efficiency.

[0012] (2) The multi-station ball conveying device of the present invention uses pipelines for direct conveying, which overcomes the problem that the fixtures for receiving small balls in the original conveying mechanism are easily damaged during use.

[0013] (3) The multi-station ball conveying device of the present invention uses pipeline conveying and is equipped with a simple positioning mechanism to realize the conveying and positioning of small balls. The structure is simplified, the processing is simple, and the cost is greatly reduced. At the same time, there are no too many complex mechanisms, which makes the failure rate of the whole line low and easy to maintain.

[0014] (4) The multi-station ball conveying device of the present invention can realize dual-station detection on a single device by adding a simple positioning mechanism on the pipeline and a set of rotating detection mechanism on the same device, thereby greatly improving the detection efficiency at a low cost.

[0015] Another objective of this invention is to provide an X-ray detection device to solve the problem that existing detection devices can only perform single detections and have low working efficiency.

[0016] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0017] An X-ray inspection device includes a radiation-proof enclosure and a multi-station spherical conveying device, a material discharge sorting mechanism, a pipe support mechanism, and multiple rotating inspection mechanisms disposed within it. The material limited by each inspection limiting mechanism in the multi-station spherical conveying device is within the inspection range of one of the rotating inspection mechanisms. The multi-station spherical conveying device is supported by the pipe support mechanism, and its height gradually decreases from the inlet end to the outlet end. The height and angle of the pipe support mechanism are adjustable. The outlet sorting mechanism is provided at the end of the multi-station spherical conveying device. The multi-station spherical conveying device, the outlet sorting mechanism, and the multiple rotating inspection mechanisms are respectively signal-connected to a controller.

[0018] Furthermore, the pipe support mechanism includes a pipe bracket, a profile is movably installed above the pipe bracket, and a pipe clamp mounting block is fixedly installed above the profile. The pipe clamp mounting block is movably connected to the pipe clamp via a locking shaft.

[0019] Furthermore, elongated holes are made on both sides of the pipe support, and a nut with a screw is placed in the nut groove of the profile. A hexagonal nut is installed at the elongated hole of the pipe support, so that the pipe support and profile can extend and retract vertically.

[0020] Furthermore, the pipe clamp mounting block has a through hole on one side and a threaded hole on the other side. After the pipe clamp is rotated to the required position, the locking shaft is rotated to lock the pipe.

[0021] Furthermore, the feed inlet of the multi-station spherical conveying device is located outside the radiation-proof box.

[0022] The X-ray detection equipment described above has the same advantages over existing technologies as the multi-station sphere conveying device, and will not be repeated here. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 3As shown, a multi-station ball conveying device 3 includes a conveying pipe 31 and a feed inlet 37, a counting sensor 34, a limiting and storing mechanism 35, and multiple detection and limiting mechanisms arranged sequentially from the feed end to the discharge end. The counting sensor 34, the limiting and storing mechanism 35, and the multiple detection and limiting mechanisms are respectively connected to a controller, which can be the main controller of the production line or the controller in the central control room, and the controller can be a PLC. The conveying pipe 31 is also equipped with a dust suction interface 36 and several pipe blowing interfaces 38. The dust suction interface 36, the pipe blowing interfaces 38, and the conveying pipe 31 form a dust removal channel to facilitate dust removal of the balls. The pipe blowing interfaces 38 are connected in series through air pipes and T-joints. Compressed air is used to blow away the dust that falls from the small balls inside the conveying pipe 31, and the dust is sucked away by a dust suction device connected to the dust suction interface 36, thereby achieving the function of cleaning the pipe. This solution has a simple structure, a high degree of automation, good quality components, is not easily damaged, and has a long service life, thereby reducing production costs. Using a pipeline transportation method with a simple positioning mechanism, the transportation and positioning of small balls can be realized. The structure is simplified, the processing is simple, and the cost is greatly reduced. At the same time, without too many complex mechanisms, the failure rate of the entire line is low and maintenance is convenient.

[0037] The feed inlet 37 is funnel-shaped or horn-shaped for easy feeding.

[0038] Preferably, the conveying pipe 31 is composed of multiple sequentially connected conveying single pipes, which can be straight or bent. Therefore, the conveying pipe 31 can be composed of multiple straight pipes, multiple bent pipes, or a mixture of straight and bent pipes, depending on the actual situation. Direct conveying via pipeline overcomes the problem of easy damage to the fixtures that receive small balls in the original conveying mechanism during use.

[0039] In this embodiment, there are two detection limiting mechanisms: a first detection limiting mechanism 32 and a second detection limiting mechanism 33. The first detection limiting mechanism 32 includes a rotary cylinder 321, a mounting plate 322, a connecting shaft 323, and a limiting plate 324. An arc-shaped groove 311 is provided on the conveying pipe 31 for placing the limiting plate 324. The rotary cylinder 321 is fixedly connected to the outside of the conveying pipe 31 via the mounting plate 322. The rotation shaft of the rotary cylinder 321 is fixedly connected to the limiting plate 324 via the connecting shaft 323, so that when the rotary cylinder 321 operates, it can drive the limiting plate 324 to rotate. When the limiting plate 324 is located inside the arc-shaped groove 311, it can prevent the ball inside the conveying pipe 31 from passing through, thus achieving a limiting function. The rotary cylinder 321 is connected to the controller via a signal; any common cylinder that can be connected to the controller is acceptable. The counting sensor 34 is a photoelectric sensor.

[0040] The limiting and storing mechanism 35 includes a dual-axis cylinder 351, a connecting plate 352, and a baffle 353. The conveying pipe 31 is provided with a groove for inserting the baffle 353. The dual-axis cylinder 351 is signal-connected to the controller. The fixed end of the dual-axis cylinder 351 is fixedly connected to the conveying pipe 31, and the movable end is fixedly connected to the connecting plate 352. The other end of the connecting plate 352 is fixedly connected to the baffle 353. The baffle 353 is inserted into the conveying pipe 31, so that when the dual-axis cylinder 351 works, it can drive the baffle 353 into or out of the conveying pipe 31, thereby limiting the ball as needed.

[0041] The working principle of a multi-station ball conveying device 3 is as follows:

[0042] Initially, the limiting and storing mechanism 35 and the first detection limiting mechanism 32 are both in a non-limiting state, while the second detection limiting mechanism 33 is in a limiting state. For ease of understanding, this example assumes that the limiting mechanism requires 3 balls. The first cycle is as follows: the balls enter the conveyor pipe 31 directly from the previous station on the production line through the feed inlet 37. After the counting sensor 34 detects the passage of the first group of 3 balls, it transmits the data to the controller, which then controls the previous station to stop feeding balls. At this time, the first group of 3 balls reaches the second detection limiting mechanism 33, reaching the set time. Then, the controller controls the rotary cylinder 321 of the first detection mechanism 33 to work. The rotary cylinder 321 drives the limit plate 324 into the conveying pipe 31 for limiting. At the same time, the controller controls the previous station to feed. After the three balls in the second group pass the counting sensor 34, the counting sensor 34 transmits the data to the controller, and the controller controls the previous station to stop feeding. At this time, the three balls in the second group reach the first detection limit mechanism 32. After the set time is reached, the controller controls the dual-axis cylinder 351 to work. The dual-axis cylinder 351 drives the baffle 353 to insert. The balls enter the conveying pipe 31, blocking subsequent balls from entering. Simultaneously, the controller controls the previous station to continue feeding. After the three balls in the third group pass the counting sensor 34, the counting sensor 34 transmits data to the controller, which then controls the previous station to stop feeding. At this point, the three balls in the third group reach the limit storage mechanism 35. While the three balls in the third group are feeding, the balls in the first and second groups can perform other processes without waiting, greatly improving work efficiency. When the second cycle begins, the controller receives signals regarding the subsequent working conditions. The dual-axis cylinder of the control limit storage mechanism 35 and the rotary cylinder 321 of the first detection limit mechanism 32 work simultaneously, so that both the limit storage mechanism 35 and the first detection limit mechanism 32 are in a non-limited state. At this time, the three balls of the third group directly enter the second detection limit mechanism 33, and then the steps of the first cycle are repeated. This step allows the material at the limit storage mechanism 35 to directly enter the second limit detection mechanism 33, which greatly saves time compared to the material reaching the second limit detection mechanism 33 from the feed port 37, and at the same time meets the requirements of dual workstations.

[0043] like Figures 4 to 6 As shown, a multi-station X-ray inspection device includes a radiation-proof enclosure 6 and a multi-station spherical conveying device 3, a material discharge and sorting mechanism 4, a pipe support mechanism 5, and multiple rotating inspection mechanisms disposed within it. The material limited by each inspection limiting mechanism in the multi-station spherical conveying device 3 is within the inspection range of one rotating inspection mechanism. The multi-station spherical conveying device 3 is supported by the pipe support mechanism 5, and its height gradually decreases from the inlet end to the outlet end. The height and angle of the pipe support mechanism 5 are adjustable, allowing the sphere to roll along the pipe by gravity, avoiding the use of additional drive equipment and reducing production costs. The outlet and sorting mechanism 4 is located at the end of the multi-station spherical conveying device 3, used to sort the inspected material. The multi-station spherical conveying device 3, the outlet and sorting mechanism 4, and the multiple rotating inspection mechanisms are each signal-connected to a controller. The inlet 37 of the multi-station spherical conveying device 3 is located outside the radiation-proof enclosure 6. By adding a simple positioning mechanism to the pipeline and equipping it with a rotating detection mechanism on the same equipment, dual-station detection can be achieved on a single device, which greatly improves detection efficiency at a relatively low cost.

[0044] In this embodiment, the multi-station ball conveying device 3 has two detection limiting mechanisms, namely detection limiting mechanism 32 and detection limiting mechanism 33. Correspondingly, there are two rotating detection mechanisms, namely rotating detection mechanism 1 and rotating detection mechanism 2. The rotating detection mechanisms can be common non-destructive X-ray inspection machines. The discharge sorting mechanism 4 can be any existing mechanism capable of sorting balls.

[0045] The pipe support mechanism 5 includes a pipe support 51, a profile 52, a pipe clamp mounting block 53, a locking shaft 54, and a pipe clamp 55. The profile 52 is movably installed above the pipe support 51, and the pipe clamp mounting block 53 is fixedly installed above the profile 52. The pipe clamp mounting block 53 is movably connected to the pipe clamp 55 through the locking shaft 54.

[0046] Specifically, the pipe support 51 has elongated holes on both sides. A nut with a screw is placed in the nut groove of the profile 52, and a hexagonal nut is installed at the corresponding elongated hole of the pipe support 51. After adjusting to the required length, the nut is tightened, allowing the pipe support 51 and profile 52 to extend and retract vertically. The pipe clamp mounting block 53 has a through hole on one side and a threaded hole on the other. After the pipe clamp 55 is rotated to the required position, the locking shaft 54 ​​is rotated to lock the pipe clamp 55. This design allows for height adjustment and locking, and the head can be rotated via a shaft. These two degrees of freedom allow for installation and support of the pipe at various positions. The simplified design makes it easier for installers to adjust flexibly according to requirements.

[0047] The assembly principle of a multi-station X-ray inspection device is as follows:

[0048] To make it easier to understand, let's take a two-workstation example:

[0049] The multi-station ball conveying device 3 is supported by multiple pipe support mechanisms 5, and the height and angle of the multiple pipe support mechanisms 5 are adjusted so that the height of the multi-station ball conveying device 3 gradually decreases from the feeding end to the discharging end. The most important thing is to ensure that the vertical plate 11 and the bottom plate 12 of the rotating detection mechanism are installed at an inclination angle, and the inclination angle is the same as the inclination angle of the conveying pipe 31, so that the pipe axis is perpendicular to the vertical plate 11. At the same time, it is ensured that the first detection limiting mechanism 32 of the multi-station ball conveying device 3 is within the range of the first rotating detection mechanism 1, and the second detection limiting mechanism 33 is within the detection range of the second rotating detection mechanism 2.

[0050] The working principle of a multi-station X-ray inspection device is as follows:

[0051] When the first group of materials from the previous station arrives at the second detection limit mechanism 33 through the feed inlet 37, the second rotary detection mechanism 2 detects the first group of materials and feeds the result back to the controller. The controller controls the second detection limit mechanism 33 to release the detected materials based on the detection result, and simultaneously controls the discharge sorting mechanism 4 to sort the detected materials. When the second group of materials arrives at the first detection limit mechanism 32, the first rotary detection mechanism 2 detects the second group of materials and feeds the result back to the controller. The controller controls the first detection limit mechanism 32 to release the detected materials based on the detection result, and simultaneously controls the discharge sorting mechanism 4 to sort the detected materials. During the detection of the second group of materials, the third group of materials has already arrived at the limit storage mechanism 35, and it will not affect the detection of the first and second groups of materials, greatly improving work efficiency. After the second group of materials is detected, the controller will simultaneously control the second detection limit mechanism 32 to switch to the limit state, while the limit storage mechanism 35 and the first detection limit mechanism 32 are both in the non-limit state. The above process can be repeated sequentially.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
