Description

Technical Field

[0001] This application relates to the field of X-ray inspection technology, and in particular to an X-ray inspection machine. Background Technology

[0002] With economic development, X-ray inspection machines have been applied to various industries. These machines can perform online inspections of packaged food, bulk food, packaged pharmaceuticals, and bulk pharmaceuticals, checking for foreign objects, shapes, material composition, and packaging integrity. Compared to manual inspection, this significantly improves inspection efficiency and product qualification rates, saving time and labor costs. However, current X-ray inspection machines have several shortcomings. For example, the X-rays must pass through a belt between the X-ray emitting component and the X-ray detection component, affecting detection accuracy. Furthermore, the unreasonable layout of internal components hinders heat dissipation, affecting component lifespan and increasing maintenance costs. Utility Model Content

[0003] To address the aforementioned problems, this application provides an X-ray inspection machine. This application arranges related components in layers, which facilitates individual heat dissipation for components in each layer and reduces mutual interference between layers. Furthermore, by setting a first preset gap between adjacent ends of two conveyor belts, the X-rays emitted by the X-ray emitting component pass through the first preset gap and are received by the X-ray detection component. This avoids the absorption of X-rays by the conveyor belts and improves detection accuracy. The technical solution adopted in this application is as follows:

[0004] An X-ray inspection machine includes: an inspection machine housing, an industrial control computer assembly, a conveying mechanism, a rejection mechanism, an X-ray detection assembly, an X-ray emission assembly, and a control panel;

[0005] The space inside the housing of the detection machine is physically divided vertically into three layers: upper, middle, and lower. The industrial control computer component is located in the lower layer, the conveying mechanism, the rejection mechanism, and the X-ray detection component are located in the middle layer, and the X-ray emission component and the control screen are located in the upper layer.

[0006] The conveying mechanism includes an input conveyor belt and an output conveyor belt, which are arranged sequentially along a first direction. There is a first preset gap between two adjacent ends of the input conveyor belt and the output conveyor belt. The X-ray emitted by the X-ray emitting component passes through the first preset gap and is received by the X-ray detection component. The detection machine housing has an input port and an output port on two opposite sides perpendicular to the first direction.

[0007] The testing machine housing has a defect rejection port on one side parallel to the first direction; when the defective product moves along the first direction towards the output port on the output conveyor belt, it passes through the rejection mechanism and is driven by the rejection mechanism to be discharged from the defect rejection port.

[0008] By layering the relevant components, individual heat dissipation of components in each layer is facilitated, reducing mutual interference between layers. Furthermore, by setting a first preset gap between adjacent ends of the two conveyor belts, the X-rays emitted by the X-ray emitting component pass through this gap before being received by the X-ray detection component. This avoids absorption of X-rays by the conveyor belts and improves detection accuracy.

[0009] In some embodiments, the testing machine housing is provided with an upper partition, a middle partition, and a lower partition. The space between the lower partition and the middle partition is the lower space, and the space between the middle partition and the upper partition is the middle space. The testing machine housing includes a support frame and an outer shell, with the outer shell supported by the support frame. The support frame includes a vertical support, a lower horizontal support, and a middle horizontal support. The lower partition is installed on the lower horizontal support, the middle partition is installed on the middle horizontal support, and the upper partition is installed at the top of the vertical support.

[0010] The horizontal support has at least two supporting rods that extend along the first direction; the conveying mechanism and the X-ray detection assembly are mounted on the supporting rods.

[0011] By incorporating a support frame, the overall structural strength and stability of the X-ray inspection machine housing are ensured, reducing the risk of deformation and damage during handling, transportation, and use. By supporting the support rod on a mid-level support, the support frame provides stable support for the support rod, ensuring the stability of the conveying mechanism and X-ray detection components mounted on it. Furthermore, the conveying mechanism and X-ray detection components can be assembled onto the support rod outside the inspection machine housing, and then the entire assembly formed by the conveying mechanism, X-ray detection components, and support rod can be installed inside the inspection machine housing. This facilitates the installation of the conveying mechanism and X-ray detection components, improving assembly efficiency.

[0012] In some embodiments, baffles are provided on both sides of the conveying path of the input conveyor belt and the output conveyor belt to prevent products from running out of the conveying path.

[0013] By setting up baffles, products can be prevented from protruding beyond the width of the conveyor belt, thus avoiding the inability to scan the entire product and ensuring that the entire product can be scanned, guaranteeing detection accuracy and ensuring that defective products are not missed.

[0014] In some embodiments, an inclined chute is provided on one side of the output conveyor belt, the inlet of the chute is located on one side of the output conveyor belt, the inlet of the chute is higher than the outlet of the chute, and the chute extends out of the housing of the inspection machine from the defective product rejection port; when the defective product moves along the first direction on the output conveyor belt toward the output port, it passes through the rejection mechanism, and the rejection mechanism drives the defective product to enter the chute from the inlet of the chute and exit from the outlet of the chute.

[0015] By setting up a chute, defective products will automatically slide out from the chute outlet after entering the chute. This reduces the driving force required for the rejection mechanism to drive the defective products, thereby reducing the working power required by the rejection mechanism and saving electricity.

[0016] In some embodiments, height-adjustable support feet are provided at each of the four bottom corners of the X-ray inspection machine housing. By providing height-adjustable support feet, leveling of the entire X-ray inspection machine is facilitated, enabling rapid leveling of the X-ray inspection machine.

[0017] In some embodiments, a double door is provided on one side of the housing of the inspection machine parallel to the first direction. The double door is opposite to the side where the defective product rejection port is provided, and the double door vertically covers the middle space and the lower space.

[0018] By installing double doors, the maintenance of the X-ray inspection machine can be facilitated. In addition, the double doors require little space to open and close, making them particularly suitable for situations with limited space.

[0019] In some embodiments, the rejection mechanism is an air-blowing rejection mechanism, which includes a flat air nozzle with at least one exhaust hole. Each row of exhaust holes is arranged along the first direction. When the defective product moves along the first direction towards the output port on the output conveyor belt, it passes through the air nozzle and is driven by the gas blown out of the exhaust hole to be discharged from the defective product rejection port.

[0020] The rejection mechanism can specifically be a flip-plate rejection mechanism, a push-plate rejection mechanism, a pneumatic rejection mechanism, or an air-blowing rejection mechanism. The air-blowing rejection mechanism uses high-pressure airflow to blow defective products off the conveyor belt. Compared to other types of rejection mechanisms, the air-blowing rejection mechanism has advantages such as requiring no mechanical movement, no contact with the product, and occupying less space, making it particularly suitable for high-speed inspection scenarios.

[0021] In some embodiments, both the input port and the output port are equipped with protective lead curtains.

[0022] By installing protective lead curtains, radiation leakage of X-rays can be prevented, avoiding harm to operators and ensuring the safety of the environment around the X-ray inspection machine.

[0023] In some embodiments, the middle space is provided with a transparent cover along its horizontal periphery, and the vertical height of the transparent cover covers the output port and the input port.

[0024] By installing a transparent cover, it is possible to observe whether any material is falling inside the X-ray inspection machine while it is in operation.

[0025] In some embodiments, a three-color tower light is provided on the top of the outer casing of the testing machine. The three-color tower light is foldable so that it can switch between a vertical and a horizontal state.

[0026] By configuring a three-color tower light, an optical alarm can be triggered when an abnormal situation occurs during the operation of the X-ray inspection machine, thus alerting the operator.

[0027] The X-ray inspection machine provided in this application has at least one of the following beneficial effects:

[0028] 1. The X-ray inspection machine provided in this application, by arranging the relevant components in layers, facilitates individual heat dissipation of the components in each layer and reduces mutual interference between layers. In addition, by setting a first preset gap between the adjacent ends of the two conveyor belts, the X-rays emitted by the X-ray emitting component pass through the first preset gap and are received by the X-ray detection component, which avoids the absorption of X-rays by the conveyor belt and improves the detection accuracy.

[0029] 2. The X-ray inspection machine provided in this application, by setting up a support frame, ensures the overall structural strength and stability of the inspection machine housing, reducing the risk of deformation and damage during handling, transportation, and use. By supporting the support rod on a mid-level support, the support frame provides stable support for the support rod, ensuring the stability of the conveying mechanism and X-ray detection assembly mounted on the support rod. Furthermore, the conveying mechanism and X-ray detection assembly can be assembled onto the support rod outside the inspection machine housing, and then the entire assembly formed by the conveying mechanism, X-ray detection assembly, and support rod can be installed inside the inspection machine housing. This facilitates the installation of the conveying mechanism and X-ray detection assembly, improving assembly efficiency.

[0030] 3. The X-ray inspection machine provided in this application can prevent the product from being exposed outside the conveyor belt along the width direction of the conveyor belt by setting a baffle, thereby avoiding the inability to scan the entire product, ensuring that the entire product can be scanned, guaranteeing the accuracy of the inspection, and ensuring that defective products are not missed.

[0031] 4. The X-ray inspection machine provided in this application has a chute. After the defective product enters the chute, it will automatically slide out from the chute outlet. This reduces the driving force required for the rejection mechanism to drive the defective product, thereby reducing the working power required for the rejection mechanism and saving electricity.

[0034] 7. The X-ray inspection machine provided in this application includes a rejection mechanism that can be a flip-plate rejection mechanism, a push-plate rejection mechanism, a pneumatic rejection mechanism, or an air-blowing rejection mechanism. The air-blowing rejection mechanism uses high-pressure airflow to blow non-conforming products away from the conveyor belt. Compared with other types of rejection mechanisms, the air-blowing rejection mechanism has advantages such as no mechanical movement, no contact with the product, and small space occupation, making it particularly suitable for high-speed inspection scenarios.

[0035] 8. The X-ray inspection machine provided in this application can prevent X-ray radiation leakage by setting a protective lead curtain, avoid harm to operators, and ensure the safety of the environment around the X-ray inspection machine.

[0036] 9. By setting a transparent cover, it is possible to observe whether there is any material falling inside the X-ray inspection machine while it is working.

[0037] 10. The X-ray inspection machine provided in this application, by being equipped with a three-color tower lamp, can issue a photoelectric alarm when an abnormal situation occurs during the operation of the X-ray inspection machine, so as to remind the operator. Attached Figure Description

[0052] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0053] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0054] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0055] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] refer to Figures 1-5 , Figures 8-10 This application provides an X-ray inspection machine, including: an inspection machine housing 1, an industrial control computer assembly 2, a conveying mechanism 3, a rejection mechanism 4, an X-ray detection assembly 5, an X-ray emission assembly 6, and a control screen 7;

[0058] The space inside the housing 1 of the inspection machine is physically divided into three layers vertically: upper, middle and lower. The industrial control computer component 2 is located in the lower space C, the conveying mechanism 3, the rejection mechanism 4 and the X-ray detection component 5 are located in the middle space B, and the X-ray emission component 6 and the control panel 7 are located in the upper space A.

[0059] The conveying mechanism 3 includes an input conveyor belt 31 and an output conveyor belt 32, which are arranged sequentially along the first direction. There is a first preset gap 33 between two adjacent ends of the input conveyor belt 31 and the output conveyor belt 32. The X-ray emitted by the X-ray emitting component 6 is received by the X-ray detection component 5 after passing through the first preset gap 33. The detection machine housing 1 has an input port 11 and an output port 12 on two opposite sides perpendicular to the first direction.

[0060] The housing 1 of the testing machine is provided with a defective product rejection port 13 on one side parallel to the first direction; when the defective product moves along the first direction to the output port 12 on the output conveyor belt 32, it passes through the rejection mechanism 4 and is driven by the rejection mechanism 4 to be discharged from the defective product rejection port 13.

[0061] The X-ray inspection machine of this application has a reasonable and compact internal component arrangement, resulting in a small overall size. By layering the relevant components, this application facilitates individual heat dissipation for each component in each layer, reducing mutual interference between layers. Furthermore, by setting a first preset gap 33 between the adjacent ends of the two conveyor belts, the X-rays emitted by the X-ray emitting component 6 pass through the first preset gap 33 and are then received by the X-ray detection component 5. This avoids the absorption of X-rays by the conveyor belts and improves the detection accuracy.

[0062] refer to Figures 3-10 In one embodiment, the testing machine housing 1 is provided with an upper partition A1, a middle partition B1 and a lower partition C1. The space between the lower partition C1 and the middle partition B1 is the lower space C, and the space between the middle partition B1 and the upper partition A1 is the middle space B. The testing machine housing 1 includes a support frame 14 and an outer shell 15, and the outer shell 15 is supported by the support frame 14. The support frame 14 includes a vertical support 141, a lower horizontal support 142 and a middle horizontal support 143. The lower partition C1 is installed on the lower horizontal support 142, the middle partition B1 is installed on the middle horizontal support 143, and the upper partition A1 is installed at the top of the vertical support 141.

[0063] At least two support rods 8 are supported on the horizontal support 143, and the support rods 8 extend along the first direction; the conveying mechanism 3 and the X-ray detection component 5 are mounted on the support rods 8.

[0064] Understandably, by setting up the support frame 14, the overall structural strength and stability of the X-ray inspection machine housing 1 are ensured, reducing the risk of deformation and damage during handling, transportation, and use. By supporting the support rod 8 on the intermediate horizontal support 143, the support frame 14 provides stable support for the support rod 8, ensuring the stability of the conveying mechanism 3 and the X-ray detection component 5 mounted on the support rod 8. Furthermore, the conveying mechanism 3 and the X-ray detection component 5 can be assembled onto the support rod 8 outside the inspection machine housing 1, and then the entire assembly formed by the conveying mechanism 3, the X-ray detection component 5, and the support rod 8 can be installed inside the inspection machine housing 1. This facilitates the installation of the conveying mechanism 3 and the X-ray detection component 5 and improves assembly efficiency.

[0065] refer to Figure 3 , Figure 4 , Figures 8-10 In one embodiment, baffles 34 are provided on both sides of the conveying paths of the input conveyor belt 31 and the output conveyor belt 32 to prevent products from running out of the conveying path.

[0066] It is understandable that by setting baffle 34, the product can be prevented from being exposed outside the conveyor belt along the width direction of the conveyor belt, thus avoiding the inability to scan the entire product, ensuring that the entire product can be scanned, guaranteeing detection accuracy, and ensuring that defective products are not missed.

[0067] It is worth noting that, reference Figure 1 , Figure 3 , Figure 5 , Figures 8-10 In one embodiment, an inclined chute 41 is provided on one side of the output conveyor belt 32. The inlet of the chute 41 is located on one side of the output conveyor belt 32, and the inlet of the chute 41 is higher than the outlet of the chute 41. The chute 41 extends out of the inspection machine housing 1 through the defective product rejection port 13. When the defective product moves along the first direction towards the output port 12 on the output conveyor belt 32, it passes through the rejection mechanism 4, and the rejection mechanism 4 drives the defective product to enter the chute 41 through the inlet of the chute 41 and exit from the outlet of the chute 41.

[0068] Understandably, by setting up the chute 41, defective products will automatically slide out of the chute 41 outlet after entering the chute 41. This reduces the driving force required by the rejection mechanism 4 to drive the defective products, thereby reducing the working power required by the rejection mechanism 4 and saving electricity.

[0069] refer to Figures 1-5 In one embodiment, height-adjustable support feet 16 are provided at each of the four bottom corners of the X-ray inspection machine housing 1. By providing height-adjustable support feet 16, the leveling of the entire X-ray inspection machine is facilitated, enabling rapid leveling of the X-ray inspection machine.

[0070] refer to Figure 2 , Figure 5 In one embodiment, a double door 17 is provided on one side of the X-ray inspection machine housing 1 parallel to the first direction. The double door 17 is opposite to the side with the defective product rejection port 13. The double door 17 vertically covers the middle space B and the lower space C. By providing the double door 17, the maintenance work of the X-ray inspection machine can be facilitated. In addition, the double door 17 requires little space to open and close, making it particularly suitable for situations with limited space.

[0071] refer to Figures 8-11 In one embodiment, the rejection mechanism 4 is an air-blowing rejection mechanism, which includes a flat air nozzle 42. The air nozzle 42 is provided with at least one exhaust hole 421, and each exhaust hole 421 is arranged along a first direction. When the defective product moves along the first direction to the output port 12 on the output conveyor belt 32, it passes through the air nozzle 42, and the gas blown out by the exhaust hole 421 drives the defective product to be discharged from the defective product rejection port 13.

[0072] It is understood that the rejection mechanism 4 can specifically be a flip-plate rejection mechanism, a push-plate rejection mechanism, a pneumatic rejection mechanism, or an air-blowing rejection mechanism. This application preferably uses an air-blowing rejection mechanism, which uses high-pressure airflow to blow non-conforming products off the conveyor belt. Compared to other types of rejection mechanisms, the air-blowing rejection mechanism has advantages such as requiring no mechanical movement, no contact with the product, and occupying less space, making it particularly suitable for high-speed inspection scenarios.

[0073] refer to Figures 1-5 In one embodiment, both the input port 11 and the output port 12 are provided with protective lead curtains 18.

[0074] It is easy to understand that by setting up the protective lead curtain 18, radiation leakage of X-rays can be avoided, harm to operators can be prevented, and the safety of the environment around the X-ray inspection machine can be ensured.

[0075] refer to Figures 1-5 In one embodiment, the middle space B is provided with a transparent cover 19 along the outer periphery in the horizontal direction, and the vertical height of the transparent cover 19 covers the output port 12 and the input port 11.

[0076] It is easy to understand that by setting up a transparent cover 19, it is possible to observe whether there is any material falling inside when the X-ray inspection machine is working.

[0077] refer to Figures 1-4 In one embodiment, a tri-color tower light 9 is provided on the top of the X-ray inspection machine housing 1. The tri-color tower light 9 is foldable, allowing it to switch between a vertical and a horizontal position. By configuring the tri-color tower light 9, an photoelectric alarm can be issued to alert the operator in case of abnormalities during the operation of the X-ray inspection machine. The foldable nature of the tri-color tower light 9 reduces the vertical space occupied during transportation.

[0078] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
